The heat wave is finally over! We’ve had so much hot weather building up over the past week, we were destined for some severe weather and that’s exactly what we got Thursday night.

That severe weather was a bit different than what we usually see with summer storms. The main difference is the storms moved slower than normal (at 15-20 mph) as opposed to the traditional 35-40 mph or the 60 mph that we’ve seen in the past few months. The slower storms reduced the damaging wind risk but also created flash flooding in areas with poor drainage. A Flash Flood Watch is in effect for most of the region through Friday morning.

Some areas saw 2-3 inches of rain in a very short period of time due to the storms.

Storms moved in around 2:30 p.m. and primarily impacted the PA Suburbs, Philadelphia, Delaware and South Jersey. In Chester County there were reports of hail, flooding, lightning and downed trees as well as power lines.

More storms moved in between 11 p.m. and 4 a.m. Our models are indicating these may be the strongest of the night south of Philadelphia, especially in Delaware and the Jersey Shore. If you’re in those areas, you should expect to be awoken by thunder during the night if you’re a light sleeper.

We're in for more rain and isolated storms Friday morning before things clear during the afternoon. However, more storms are expected over the weekend.

Severe thunderstorms slammed the region causing heavy rain and flooding Monday. A Flash Flood Warning was in effect in Philadelphia and the surrounding suburbs until 11:15 p.m. A Flood Advisory was also in effect for Philadelphia, Montgomery and Burlington counties until 9 p.m.

Many areas in the Philly region dealt with heavy, slow moving rain and flooding. I-76 eastbound was closed at the Gladwyne exit in Montgomery County due to flooding. One eastbound lane is now currently getting by.

There was also flash flooding on MLK Drive in Philadelphia.

[[388211972, C]]

    A SEPTA bus and car were also trapped in flood waters underneath a bridge on Station and Railroad avenues in Bensalem Township. Crews managed to safely get passengers off the bus.

    [[388204172, C]]

    The storms caused chaos for both the media and demonstrators during the first day of the Democratic National Convention in Philadelphia.

    [[388206012, C]]

    Storm clouds turned the skies black over Franklin Delano Roosevelt Park as hundreds of activists readied to listen to Green Party candidate Jill Stein. Some people made their way out of the park as lightning lit up the skies but others stayed to hear the speech.

    The storm quickly turned torrential Monday evening with sheets of rain blowing sideways down south Broad Street. The severe storm didn't deter a group of protesters from chanting, "Feel the Bern" up against a metal fence at Broad and Pattison however.

    Police, media, delegates and convention volunteers sought refuge from the storm at SEPTA's AT&T station near the Wells Fargo Center. Some conventioneers braved the rain however, even without umbrellas, leaving them soaked in tailored suits and summer dresses.

    Journalists were also evacuated from the DNC press center. The Democratic National Committee recommended journalists leave the media compound because there was no protection against a direct lightning strike. They were directed to Lincoln Financial Field. 

    Before the storms, residents across Pennsylvania, Delaware and New Jersey dealt with sweltering heat. By Monday afternoon we hit the midpoint of our heat wave and the hottest temperatures, too -- reaching 98 degrees. However, it felt way worse. The heat index ranged between 105 and 110 degrees.

    The dangerous heat felt far more oppressive than what we’ve seen so far. The heat also fueled the storms Monday afternoon and evening leading to lightning, heavy rain, strong wind and flooding.

    This same pattern continues for Tuesday, Wednesday and Thursday. The temperatures decrease very gradually and the humidity comes down a bit as well. The next active storm day will be Thursday where a 92 degree forecast will be coupled with muggy conditions, and feel like 100. There will also be strong afternoon storms.

    If you’re coming to our city for the convention, welcome. We’ll keep you posted right here as the weather changes. If you’re from around here, I’m sure you’ve been thinking about heading to the Shore if you haven’t already. It’s going to be 5-10 degrees cooler there, so burn some of that extra vacation time and beat the heat (and the crowds).

    [[388061082, C]]

    A number of local municipalities are taking measures to help people stay cool and protect residents from serious health problems excessive heat can cause. Allentown reduced fees at its public pools, allowing residents to swim for free through the heat wave.

    In Philadelphia, the Heat Line is up and running at 215-765-9040, and in Montgomery County, officials issued a code red through 6 p.m. on Tuesday for excessive heat.

    A woman is recovering after violent storms caused a tree to fall on top of her car in Magnolia, New Jersey Saturday afternoon.

    [[388039272, C]]

    The tree crashed onto a car on Lincoln Avenue, trapping a woman inside. Responding firefighters managed to get the woman out. A woman who witnessed the rescue told NBC10 the victim appeared to be conscious and alert as she was brought out. Officials have not yet revealed her condition however.

    [[388036972, C]]

    Magnolia was just one of the countless areas in the region that was hit by severe storms. The storms ripped through the region Saturday bringing heavy rain, 60 mph wind gusts, lightning and hail. A Severe Thunderstorm Warning was in effect for most of the area until 6:15 p.m.

    The storms caused thousands of power outages across the region. As of 9 p.m. PECO reported 1,606 outages, with the majority in Montgomery County, Atlantic City Electric reported 4,538, with the majority in Camden County, and PSE&G reported 6,371.

    The storms also caused a transformer fire in Hi-Nella, Camden County. The witness claimed lightning struck the pole.

      <![CDATA[Extreme Heat Wave: Smashing Records This Week/end]]> Sat, 23 Jul 2016 23:59:17 -0400 http://media.nbcphiladelphia.com/images/213*120/GettyImages-81502754_ola+de+calor.jpg


      We hit 94 in Philadelphia on Friday. 94 is a kind of been there, done that type of heat. We’ve gotten to 94 four times in the past ten days. However, Saturday’s high of 98 is a different story. We haven’t gotten to 98 since July of 2013.

      [[388038212, C]]

      It’s all thanks to a massive dome of heat prompted by a giant dome of high pressure bringing in wind from the West Southwest. If you’re wondering why we’re hitting 92 on the beach at the shore, it’s because of that wind (and yes, we’re hitting the 90s on the sand at the shore, sorry.) Needless to say, the burn time is an exceptionally quick 10 minutes, so sunscreen is a must, as is lots and lots of water.

      [[388006882, C]]

      Saturday is our Clear The Shelters day here at NBC10, so whether you’re adopting a pet or have had one for a while, we cannot stress the importance of not leaving your pet (or your kids) in a closed car, even with the windows cracked. It takes just 60 minutes for your closed up car to hit 140 degrees in our weather, which is the temperature you cook steak to, so make sure you pay extra attention to this.

      Sunday will be slightly cooler, 97 in Philadelphia and 90 at the Shore. We’ll be within a degree of Philadelphia’s record on Sunday. The humidity will creep up a bit on Sunday, as well. That means the 97 will feel somewhere around 102-104.

      The high 90s roll right through to Monday, when we top out at 99, a new record for the day and a feat we haven’t accomplished on any day in the calendar in over four years.

      On top of that 99, it will be very humid, so that 99 will feel close to 110 degrees. A heat that high combined with bad air quality means you shouldn’t be doing any physical activity outside (we give you permission to take the day off) and you should stay indoors as much as possible. There are also some storms rolling through for Monday.


      We’re looking at an eight day heat wave here, as temperatures head to the mid-90s for Tuesday and Wednesday and then the sweet, sweet relief of low-90s for Thursday and Friday (not sure 90 counts as relief, but hey…we’ll take what we can get.)

      <![CDATA[Dangerous Heat for the DNC]]> Thu, 21 Jul 2016 01:20:15 -0400 http://media.nbcphiladelphia.com/images/191*120/WFCamp.JPG


      There’s no easy way to put this…this weekend is going to be a scorcher. We’re forecasting a high of 97 degrees, which is the warmest we’ve been since July 18, 2013, over three years ago. If you can escape to the beaches, it will be a little cooler (somewhere around 90) but the sea breeze won’t be as potent as usual. That’s because our sea surface temperatures are running at least 5 degrees above average. If you’re just coming in to town for the convention, think about a day trip to the Jersey Shore until convention activities get started on Monday. Sightseeing in Philadelphia will be exceptionally hot. The good news for Saturday is that humidity will be low, so at least it’s a dry heat. Some places in our area will likely hit 100, though.[[387685871,C]]

      Sunday will have the same outdoor air temperature but the humidity will already start to creep up a bit. That same 97 will feel like 101 or 102. Things get even worse on Monday, when the dew points move firmly into the oppressive category. The heat index will range between 105 and 110 degrees. This is very dangerous heat. Because of the moisture in the atmosphere, your sweat won’t actually cool you down all that much and it is very easy to get dehydrated. If you’re out protesting, the pavement will absorb the heat and hold on to it long after the sun goes down, in something called the “urban heat island effect.” We will hit the 90s before noon and stay there through 7 PM. Even the night won’t provide much relief, as we’re forecasting a low in the upper 70s. It’s also important to note that Monday has the best chance of thunderstorms. You’ll want to keep an eye to the sky and make sure you have some place to go through if one of them rolls through. Our NBC10 app will send a push alert when storms are 30 minutes away, which will give you ample time to get indoors somewhere. Lightning and damaging wind is possible, so it’s not a good idea to wait these out outdoors.

      The weather story is a bit of a broken record. This same pattern continues for Tuesday, Wednesday and Thursday. The temperatures decrease very gradually and the humidity comes down a bit as well, but we keep the storm threat in there for every day that week. They’ll be much more isolated but it will still be important to be weather aware. The heat index for the rest of the week will be around 100, as well.

      We’re the only ones in town with a 10 day forecast…our “10 day on 10.” Here’s the relevant days for the convention:[[387680451, C]]

      If you’re coming to our city for the convention, welcome. We’ll keep you posted right here as the weather changes. If you’re from around here and have some vacation time, I have two words for you…Shore Week. Seriously.

      A woman was killed when she made contact with a live storm-downed wire while trying to get out of her car in New Jersey Monday, police say. 

      The wire came down on the car at Midway Avenue and Ginder Place in Fanwood as storms swept through in the late afternoon, according to Fanwood Police Chief Richard Trigo. 

      The 26-year-old driver tried to get out through the passenger side and made contact with the downed wire and died, Trigo said.

      The unidentified woman was the only person in the car, Trigo said.

      A woman driving home with her 12-year-old daughter witnessed the electrocution. They said the rain was pouring when a tree branch snapped, taking down electrical wires. One of the cables fell on top of the victim's car in front of them.

      "The wire fell on this side of the car and she went through the other door, and that's when she put her elbow on one of the wires. And that's when she fell," said the daughter, Camila Chacha.

      Her mother, Eliberia Delgadillo, said she began panicking as they watched the horror unfold.

      "She said, 'Mom, relax,' I can't, I can't, I saw her when she burned," said Delgadillo, who returned to the scene with her daughter later in the evening to leave flowers. 

      "We just called 911, and we couldn't do anything right there -- we couldn't get out of the car or back up, we just had to look at her," said Camila. 

      "It was so scary, and I never want to go through anything like that ever again," she said in tears. 

      Utility companies often remind customers to stay in their cars if a live wire falls on it, especially because tires are electrical conductors -- not insulators, as many mistakenly believe. 

      "It is true that you are safe in your vehicle when a live wire falls on it. But that's because electricity always seeks the easiest path to the ground," PSE&G says. "If you remain in the vehicle, the path of the electricity will be on the outside of the vehicle, through the tires, and into the ground."

      "As long as we do not provide a path to the ground through our body the electricity will not enter it. So when an electrical wire falls on your vehicle, stay in your vehicle until help arrives and the power is shut off," PSE&G says. 

      If you must get out because of a fire or other danger, jump clear out with both feet together, making sure not to touch any other part of the car as the feet hit the ground. Then keep both feet together and hop or shuffle at least 30 feet away.

      Severe storms with lightning, heavy rain, high winds and hail ripped through the region Monday afternoon causing widespread outages and damage. A Severe Thunderstorm Watch was in effect for almost the entire region until 8 p.m.

      The FAA also issued a ground stop for flights departing to Philadelphia due to the weather. The ground stop was later canceled however.

      The storm also slammed the Lehigh Valley, leaving 16,717 PPL customers in the area without power at its peak. The weather also caused a roof to partially collapse into the first floor of a home on the 1900 block of Ronald Drive in Whitehall Township.

      "You could see the front door start shaking so bad," said Samira Salim, who was inside the house during the partial collapse. "I ran downstairs and my mom is yelling because the roof is flying. A lot of stuff. Debris is flying all over."

      Officials have not yet revealed if anyone was injured. Storms also caused widespread damage to homes and businesses in Havertown, Delaware County, including the Swiss Farms at 820 N. Eagle Road.

      "Next thing you know we had another big lightning bolt," said Dawn Gallo, the manager of Swiss Farms. "We heard this big thud."

      Scott Simon, the store's president and CEO, told NBC10 the store's 40-year-old silo collapsed in roughly 20 seconds.

      "Thank God no car was inside and no one got hurt," Simon said. "That's the most important thing. Everything else can be repaired."

      Simon told NBC10 the storm caused $100,000 in damage. They plan to rebuild the silo.

      Conditions will clear overnight and we're in for a partly sunny and less humid Tuesday with a high of 89.

      The National Weather Service has confirmed a tornado touched down in Warren County, New Jersey during Thursday's storms. 

      The EF-0 tornado touched down near White Township and skipped along a path nearly 3 miles long, damaging a barn and a home, and shearing the tops of trees.

      The owner of the barn, Tom Smith, told NBC 4 New York he saw the black funnel cloud spiral toward his 20-acre farm Thursday afternoon.

      "The first minute is silent. And they say it sounds like a freight train -- it doesn't, it sounds like 10 freight trains," said Smith. 

      Smith was out in the field with his two dogs, cutting hay, when the force of the wind picked up his 150-pound St. Bernard, who survived with just a scratch. Then the storm turned toward the barn, tearing it to pieces. 

      "I watched the whole barn disappear," he said.

      The stalks of corn across the acres of farmland were flattened, and a tractor-trailer tipped over, along with a hay wagon and 40-pound bales. 

      "I am lucky to be alive," he said. "For anyone who is watching, it's no joke."

      More than 350 people remained without power Sunday morning after strong storms swept through South Jersey on Saturday, leaving flooding and power outages in their wake.

      Atlantic City Electric's website said that 375 customers remained without power about 7:15 a.m. Sunday, the bulk of whom are in Camden County.

      The storms that blew through the area initially left about 2,000 people in the dark, an AC Electric spokesperson said, but the company restored power to most of them by morning. Other counties still seeing the most outages Sunday morning were Burlington, Cumberland and Gloucester, although AC Electric reported fewer than 100 customers with power in each of those counties.

      There was no time estimate for when power may be restored to those still in the dark.

      Nearly 2,000 people were left in the dark Saturday following severe storms in South Jersey.

      The storms brought down wires and damaged trees due to high winds, heavy rain and lightning. A spokesperson for Atlantic City Electric said that nearly 2,000 customers were without power during the peak of the storm. As of 10:30 p.m., over 1800 AC Electric customers were without power.

      The storms also caused flooding in parts of South Jersey, including Winslow Township and Atco.  Lightning also struck two women at Point Pleasant Beach, Ocean County. Both women suffered minor injuries.

      Two women are in the hospital after they were struck by lightning in Ocean County, New Jersey, Saturday afternoon.

      Police say a 63-year-old woman was at Point Pleasant Beach at the foot of New Jersey Avenue at 2:53 p.m. when she was struck by lightning. She required CPR at the scene but was alert when she was taken to the Ocean Medical Center in Brick, New Jersey, officials said.

      A 54-year-old woman who was about a half a mile away from the first woman was also struck by lightning at 3:01 p.m. while she was sitting in a vehicle in a parking lot at 300 Ocean Avenue. She was also alert while being transported to the Ocean Medical Center.

      Officials say both women suffered minor injuries and should be released from the hospital Saturday night. Both women told officials they were in the process of leaving the beach because of incoming storms before they were struck by lightning. No other injuries have been reported.

      A Severe Thunderstorm Warning is in effect for Ocean, Camden and Burlington counties in New Jersey while a Flood Advisory is also in effect for Burlington and Ocean counties.

      With temperatures expected to hit the 90s, excessive heat warnings and heat advisories were issued for much of the region for Thursday and Friday.
      The Excessive Heat Warning will be in effect for parts or all of the following counties from noon Thursday until 8 p.m. Friday:

      • Burlington, NJ
      • Camden, NJ
      • Chester, PA
      • Delaware, PA
      • Gloucester, NJ
      • Mercer, NJ
      • Montgomery, PA
      • New Castle, DE
      • Philadelphia, PA

      The Heat Advisory will be in effect for the rest of the Philadelphia region Thursday from noon to 8 p.m.

      Montgomery County declared a Cod Red Hot Weather Health Warning from noon Thursday to 6 p.m. Friday due to the heat. Philadelphia also issued a heat warning for Thursday and Friday. Philadelphia’s Heatline will be open Thursday from noon until midnight as well as Friday from 8:30 a.m. to 8 p.m. You can call the Heatline at 215-765-9040.

      “We strongly urge the public to visit older friends, relatives and neighbors to ensure that air conditioners or fans are working and homes are adequately ventilated,” said Philadelphia Health Commissioner Thomas Farley. “In a heat wave, the majority of the victims are older people and those with pre-existing medical conditions.”

      Besides the elderly, other groups at risk during extreme heat include people with chronic medical conditions, pregnant women, small children, people who work in a high heat environment and people engaged in strenuous physical activity. Residents who don’t have air conditioning in their homes are also advised to go to shopping malls, movie theaters, senior centers and other public spaces with AC for at least some part of the day.

      The Department of Health also provided the following tips to avoid heat-related illness:

      • Avoid, as much as possible, working or playing in the hot sun or other hot areas.  If you must be out in the sun, wear a head covering.  A wide brimmed hat or visor will not only protect your head from intense rays of the sun, it will also provide a shield for your eyes.
      • Use air conditioners and fans.  Open windows to release trapped hot air.
      • Those taking regular medication should consult with their physician.  Some medications cause an adverse reaction in hot weather.
      • Wear lightweight clothing.
      • Drink plenty of non-alcoholic liquids, warm or cool.  Because the body loses fluids in the heat, drinking lots of liquid helps to prevent dehydration.
      • Maintain a normal diet.
      • Shower or bathe in water that is near skin temperature.
      • Do not leave older people, children, or pets alone in cars.

      Early symptoms of heat stress include decreased energy, slight loss of appetite, faintness, light-headedness and nausea. If you experience any of these symptoms go to a cool environment, drink fluids, remove excess clothing and rest.

      Serious signs of heat stress include unconsciousness, rapid heartbeat, throbbing headache, dry skin, chest pain, mental confusion, irritability, vomiting, diarrhea, muscle cramps, staggering and difficulty breathing. If you experience any of these symptoms get medical attention immediately. CLICK HERE for more information on excessive heat.

      <![CDATA[Severe Storms Slam Region ]]> Sun, 10 Jul 2016 00:06:45 -0400 http://media.nbcphiladelphia.com/images/213*120/Lightning-Generic2.jpg

      Severe storms moved into the region Saturday leading to a ground stop, flood advisory and a severe thunderstorm warning.

      Severe thunderstorms moved into parts of the area Saturday afternoon. A Flood Advisory was in effect for Salem, New Castle, Gloucester, Delaware and Chester counties until 8:15 p.m. A Severe Thunderstorm Warning was also in effect for Delaware County, Pennsylvania, Gloucester County, New Jersey, New Castle County, Delaware and Salem County, New Jersey but later expired.

      A ground stop was in effect for flights departing to Philadelphia International Airport Saturday due to severe weather conditions. The airport announced the FAA ground stop around 4:30 p.m. and advised travelers to check the flight status of their carrier. The ground stop was later lifted around 5:45 p.m.

      The storms should clear overnight leading to sunny conditions Sunday.

      Yes, They're The Same Thing

      First things first: hurricanes and typhoons are different names for the same thing. They are both Tropical Cyclones, which also happens to be what they’re called in the Indian Ocean and the Southern Hemisphere. Here’s a map of what they’re called in different parts of the world…

      And here is a beautiful map showing tracks and intensities of all tropical storms, courtesy of NASA…

      A few things immediately stick out from looking at the map:

      1. There are more storms in the Western Pacific than any other area-by FAR.

      2. There are virtually NO storms off the west coast of the U.S.

      3. There are virtually NO storms in the South Atlantic, or in the Eastern South Pacific

      4. There are virtually NO storms close to the equator (this is because it takes the Coriolis Effect to lead to enough spin to get storms started).

      Super-Typhoon vs. Major Hurricane

      The most destructive storms on earth often look alike, but are defined differently. A "Major Hurricane" has sustained winds of at least 111 mph, which makes it a Category 3 on the Saffir-Simpson scale. A Category 4 has winds of at least 130 mph. Category 5 is greater than 156 mph. Meanwhile, a "Super-Typhoon" has sustained winds of at least 150 mph. That’s about the equivalent of a Category 5.

      The increase in winds doesn’t do justice to the huge difference in destruction from a "minimal" hurricane, with 74 mph winds to a major hurricane.

      The "potential damage" of a Category 3 is about 50 TIMES as much as a Category 1. A category 4 has about 250 TIMES the damage. And a Category 5 has about 500 TIMES the damage. You can see how important the difference is, even among major hurricanes. This is why any increase in numbers of storms of Category 4and 5 (or Super-typhoons) is a REALLY BIG DEAL. And yes, it’s happening.

      Click here to read the article the graphic is based on.

      The evidence had become obvious nearly ten years ago.

      The Superstorms Of The Past Few Years

      It has become obvious that the odds of a hurricane becoming "Major" has increased in the past decade or so. And the frequency of typhoons becoming "Super” has increased as well. This is very bad news.

      Super-typhoon Nepartak is the latest (max sustained winds 175 mph)

      2016 -- Cyclone Fantala (Indian Ocean)
      Max sustained winds: 175 mph[386060141,600,466]]

      Notice anything about Fantala? It looks backward. That’s because it is. Fantala tracked through the SOUTHERN Indian Ocean, and storms rotate in the opposite direction there. A storm this strong was unheard of in this part of the world-until recently.

      Storms as strong as SuperTyphoons and Category 5 Hurricanes should be rare, too. But it seems that more and more of them have formed in the past couple of years.

      2015 -- Soudelor (180 mph)

      2015 --Noul (160 mph)

      2015 --Maysak (160 mph)

      These are just a few of the record 22 hurricanes or typhoons that reached Category 4 or 5 in the Northern Hemisphere in 2015!

      2015 -- Patricia (East Pacific)
      Max Winds: 215 mph (world record)

      2014 -- Vongfong (180 mph)

      2013 -- Haiyan (195 mph)

      Haiyan seemed to start this recent trend of numerous, extreme storms. It was one of the strongest tropical cyclones ever recorded (and the strongest ever recorded at landfall anywhere in the world). Sustained winds reached 195 mph. Tragically, it made landfall in parts of the Philippines at near maximum strength, killing thousands and making 4 million people homeless.

      Amazingly, Haiyan’s winds were topped just 2 years later, when Patricia had sustained winds of 215 mph.

      So Why Is This Happening?

      The main answer is simple and obvious: Warmer Ocean temperatures allow any given hurricane or typhoon to become stronger. Hurricanes feed off of warm water. And if the warm ocean waters extended to a significant depth, there is an even greater chance of an intense storm.

      Several studies have shown a general increase of percentage of intense cyclones in recent years, combined with a general decrease in total number of tropical cyclones. The graphic below from noted hurricane/climate change researcher Dr. Kerry Emanuel, shows a strong connection between ocean temperatures (SST) and overall "power" of tropical cyclones (he calls it "PDI"-Power Dissipation Index):

      So, oceans are warming due to climate change, which then causes any given hurricane or typhoon to get stronger than it would be if there hadn’t been any warming. Right? Well, it’s not as simple as that.

      Is Something Else Causing Oceans To Warm?

      To be fair, I must mention a theory held by a significant number of meteorologists (but not so many climate scientists). There’s a natural cycle in Pacific Ocean temperatures called the PDO-Pacific Decadal Oscillation. It’s not important why it exists-it just does.

      So, when noted climate skeptic Dr. Ryan Maue tweeted this graphic, it raised some eyebrows of more than a few meteorologists:

      This shows how another measure of tropical cyclone "power"; called "ACE" (the blue line) correlates with the PDO. That’s pretty impressive. It also shows the El Nino/La Nina factor (ENSO). That’s also pretty impressive. After all, we just had a record strong El Nino, which warms a lot of the Pacific. We did expect the 2015 typhoon season in the Western Pacific and the 2015 hurricane season in the Eastern Pacific to be very active.

      So, could this super-typhoon trend of recent years just be temporary? If Maue is right, it is. If the intensity trend continues, though, it will become clearer that global warming is the main driver of the catastrophic super-typhoon and major hurricane trend of the past few years.

      What Does This Mean For Us?

      Last year was a record El Nino last year, which led to an inactive Atlantic hurricane season. We are now switching to a La Nina, which will help make this Atlantic hurricane season a very active one. Whether the East Coast gets hit with one will be determined by the overall weather pattern at the time they form.

      But warmer than normal ocean temperatures would:

      1. Allow any storm that forms in the Atlantic to be stronger than it would with normal ocean temperatures

      2. Allow any storm that closes in on the East Coast to weaken more slowly

      Current ocean temperatures in the Atlantic, Caribbean, and Gulf of Mexico are all above normal. And the waters along our part of the coastline and off New England are especially warm compared to normal. Here’s the map:

      With temperatures expected to feel like triple digits for the rest of the week, the NBC10 First Alert Weather Team issued a First Alert for Philadelphia and the immediate suburbs through Friday afternoon.

      People should plan on limiting outdoor activity as temps push into the upper 90s Thursday and Friday afternoon as the area enters a heat wave (three straight days of highs of 90 degrees or more).

      Poor air quality and humidity could cause difficulties for people with respiratory problems as the heat index hits 100 degrees or more (highs are expected to hit 97 both days with a feel-like temp of 104). The Excessive Heat warning covers Philadelphia, Wilmington and Trenton as well as parts of South Jersey, Delaware County, Montgomery County, Chester County and Bucks County. [[52883697, C]]

      "Temperatures will be running around 10 degrees above normal, and it’s this hot humid weather pattern that’s causing poor air quality," said NBC10 First Alert Weather meteorologist Sheena Parveen.

      Besides the hot, hazy conditions, a thunderstorm could strike both Thursday and Friday.

      After another day in the 90s Saturday, temps finally cool off Sunday as temps will only reach the 80s.

      Here Comes the Heat
      We certainly haven’t seen much heat so far this summer season. Since Memorial Day, we’ve only had five days of 90-plus-degree temperatures in Philadelphia. And the 4th of July only hit 80 degrees (after only 78 on the 3rd). The highest temperature has only been 92 degrees, so there’s been nothing close to extreme heat.

      We certainly can get mighty hot this early in summer-our record for the 4th was 103 degrees in 1966! But here it comes….

      Building Heat

      Temperatures on the 4th of July were far below normal from the Mid-Atlantic States all the way west to Kansas (in the blue and purple areas) [[385667161, C]]

      The heat really starts to build Wednesday, as the blue colors turn to orange and red. Now we’re talking about temperatures well above normal, even for July:[[385667311, C]]

      And, the heat will build even more. By Friday, temperatures will be in the 90s (at least) from Maine to Florida. Since the humidity will be high as well, we’ll be having "feels like" temperatures well above 100 degrees. So, watch out for likely heat advisories later in the week. [[385667761, C]]

      The heat should last through Saturday. We expect to be back down into the 80s by Sunday and Monday.

      If you or someone you know needs help dealing with the heat, contact the City of Philadelphia's heat line at 215-765-9040.

      Once the rain cleared Tuesday morning, things began heating up.

      Higher up in the atmosphere an area of high pressure will form, which in turn will heat up our air allowing for temperatures to warm into the 90s.

      We’re looking at a stretch of 90-degree temps possibly starting Tuesday afternoon, then Wednesday through Saturday.

      Highs will mainly be in the mid-90s Wednesday to Saturday with the possibility of afternoon thunderstorms.

      Dew points should stay fairly high, around 70 degrees, which makes the air more humid. So expect a hot, humid rest of the week with afternoon storms starting Thursday.

      Widespread rain hit the area late Monday night, with the heaviest rainfall coming after midnight. A second burst of heavy rain will follow into Tuesday morning's commute that led to a Flash Flood Watch for much of the Philadelphia region.

      NBC10 issued a First Alert from 3 a.m. until 9 a.m. for Tuesday across the viewing area, except for Lehigh and Berks counties. That's due to a Flash Flood threat, NBC10 First Alert Weather chief meteorologist Glenn "Hurricane" Schwartz explained.

      By 5:30 a.m. Tuesday, the National Weather Service had trimmed the Flash Flood Watch to South Jersey and Delaware.

      Once the rain moves out the heat moves in with humidity.

      Glenn says we're in for the hottest week of the summer.

      Schwartz predicts temperatures to soar past 90 degrees Wednesday through Saturday. Shore temps stay above 80.

      If you’re heading out to a barbecue Monday or to other Independence Day festivities make sure you bring your umbrella and maybe plan on getting an early start. Widespread rain could put a damper on the July 4th holiday.

      "If you're interested in barbecuing I recommend the earliest start you can get away with," said NBC10 First Alert Weather chief meteorologist Glenn "Hurricane" Schwartz. "Everyone is going to have a rainy night."

      A Flash Flood Watch was put into effect for much of the Philadelphia region as clouds built Monday afternoon. Rain began moving in from southwest to northeast by later Monday afternoon into evening as temps push toward 80.

      Showers moved into southern Delaware by early afternoon and could spread into Philadelphia as well as south and east of the city by 4 p.m.

      The NBC10 Weather Team recommends that anyone heading outdoors for a barbecue or another event in Philly or south and east of the city be prepared to possibly get wet.

      "You should have the umbrella ready to go," NBC10 meteorologist Erika Martin.

      With conditions soupy, heavy thunderstorms could strike Delaware and other parts of the region by early evening but overall this should be a mostly rain event.

      "Every hour that goes by after, let's say 5 o'clock, the chance of rain gets higher, the chance of more significant rain gets higher," said Glenn. "We're not talking about downpours but it's going to be a whole lot nicer at 4 o'clock than it will be around 8 o'clock."

      With the potential for embedded thunderstorms Monday evening/night, there is the concern for thunder and lightning.

      "Everybody will see rain, it will probably get heavier in Delaware than it does elsewhere," said Glenn.

      The threat of rain caused some municipalities to postpone fireworks for Monday night.

      The Wawa Welcome America July 4th fireworks on the Benjamin Franklin Parkway remain scheduled for 10 p.m. Organizers have a strict protocol in place in case of lightning. If there is a lightning strike within 10 miles of the venue, stage technicians will be placed on alert. If there is a lightning strike within eight miles, rigging, lighting and camera tower staff will be moved to ground level and performances will be temporarily halted. A Public Safety Policy Group will then gather to discuss a possible Parkway evacuation depending on the severity of the storm.

      The event also has a high wind policy. If winds reach higher than 40 mph, all show operations will cease and the stage area will be evacuated. If they reach higher than 50 mph the entire venue will be evacuated.

      For those attending the concert, you're allowed to bring umbrellas as long as they're not beach umbrellas or have a sharp or pointy top. Tents, canopies and camping equipment are also not allowed.

      The showers will continue on and off overnight into Tuesday morning -- with the potential for severe storms between 4 to 7 a.m. -- before the system finally moves out Tuesday afternoon. After the rain the next issue will be the heat.

      "We could have some of the hottest, most excessive heat we’ve seen Wednesday through Saturday," meteorologist Karen Thomas said.

      Wednesday’s high is expected to push toward 90. More 90s are expected through Saturday. Stay with NBC10.com for the latest updates on 4th of July weather.

      A man recorded video of a possible funnel cloud in Millville, New Jersey Friday afternoon as severe storms moved through the region. Joe Lacivita said he spotted it near Route 49 and Sugarman Avenue around 4:30 p.m.

      Officials have not yet confirmed whether a funnel cloud actually touched down in the area. NBC10 First Alert Weather chief meteorologist Glenn Schwartz says it’s possible however given the conditions Friday.

      “In that area we did detect some rotation in the clouds on the Doppler Radar so it is possible,” Glenn said. “It was over a field so we don’t have any damage to investigate.”

      The possible funnel cloud was spotted amid a stormy day in South Jersey in which several areas, including Vineland, dealt with flash flooding.

      There hasn’t been a lot of rain this month, but when there has been some rain around, it’s been heavy at times, and with gusty thunderstorms, too. Friday should be one of those days. But don’t let it give you the idea that the whole holiday weekend will be wet and stormy.

      Here are the computer model maps for Friday at 8 a.m. and 8 p.m.:

      [[385107151, C]]

      [[385107381, C]]

      The top map shows locally heavy showers and storms at the Jersey Shore and the Delaware beaches. The bottom one shows a separate area that will develop west of our area and move in late in the day.

      The best weather of the weekend will come Saturday and into at least a part of Sunday. HIGH pressure will build in behind the Friday night storms, giving us a lot of sunshine and lower humidity. Then things get interesting. (When a meteorologist uses the word “interesting,” chances are you’re not going to like what comes after that word.

      For Sunday, the question is how much sunshine different parts of our area will see. In general, one area of moisture will be sitting just south of the area Sunday morning (see below):

      [[385107441, C]]

      The colors represent clouds (the brighter the color, the thicker the clouds). Notice a band of clouds in southern Delaware. That’s pretty close to the beaches. Obviously, the farther north you go, the greater the chance of full sunshine Sunday.

      Here’s the same map for Monday at 8am:

      [[385109731, C]]

      We still see the band of clouds just south of the Philadelphia area, but it’s clear that a big area of clouds is approaching from the west. By 8 p.m., those clouds have overspread the area:

      [[385109821, C]]

      So, the conclusion is that we’re predicting increasing cloudiness Monday, with a chance of rain by Monday night, especially in areas south of Philadelphia. The rain chances continue into Tuesday.

      So, if you want a day with full sunshine, Saturday is the best bet, and Monday is the day most likely to be cloudy. We could still manage to stay dry from Saturday morning all the way through Monday evening, but it may be a close call. More tomorrow with the latest data.

      Tuesday wasn't exactly the best day. It was overcast outside for much of the area, and the humidity was pretty nasty. Tuesday night, the Lehigh Valley, Berks County and the Pennsylvania suburbs all saw storms with heavy rain.


      The biggest threat from these storms was damaging wind, gusting to 50 miles per hour or more. There was also frequent lightning strikes. Because those storms came during evening rush hours, heavy rain and some roadway flooding was a concern. They didn't really move very fast. You almost never see thunderstorms move at 25 miles per hour (usually they’re moving at 40 miles per hour or more), so the concern was about roadway flooding as the rain sat over places longer than it normally does.


      Some storms moved into Philly, Delaware and South Jersey late Tuesday night but they had weakened by the time they moved in. The rain moved out around midnight.

      Wednesday will be mostly sunny with a high of 86 while Thursday will also be sunny with a high of 88. The next chance of rain we'll see is for Friday afternoon.

      <![CDATA[July 4th Weekend Forecast]]> Fri, 24 Jun 2016 21:55:20 -0400 http://media.nbcphiladelphia.com/images/213*120/Philly+Hot+Sun_19898880.jpg


      We’ve already seen some great weather on weekends this summer. The past two weekends have been near perfect (although a bit on the hot side). No rain; lots of sunshine; low humidity for summer. And the upcoming weekend will make it 3 in a row. Not a drop of rain. 

      The pattern is straight-forward. Upper-air maps for Sunday morning show a strong ridge of high pressure from Mississippi to New England. Higher pressures than average are colored in red. 

      This leads to high pressure dominating the Eastern U.S. at the surface:

      Once again, the red areas have pressures above normal. The reddest colors are right over our area, indicating HIGH pressure practically overhead. That means not much wind, lots of sunshine, and low humidity. So this weekend is a “slam dunk” (in honor of the Sixers new, future star). 



      SATURDAY 86 76 (Ocean 65 degrees)

      SUNDAY 87 76

      Onshore breezes each day 


      It may not turn out to be bad, but next weekend is not likely to be a repeat of this one. We’re talking about days 8, 9, and 10 of our 10-Day Forecast, so it’s still pretty far out. But there are some general clues emerging. 

      Any longer-range forecast has to start with a look at the upper levels of the atmosphere. Computer models do a much better job with them than any kind of surface forecast. Sometimes, the models show a high level of confidence in a certain type of overall pattern. That pattern doesn’t look very much like the one for this weekend. 

      Here is an upper-air map, similar to the one at the beginning of this blog. See if you notice the clear differences: 

      This is the same computer model, predicting pressures at “500mb” (about 18,000 feet up), which is the standard level meteorologists use for this type of forecasting. Instead of that HIGH pressure ridge in the Eastern U.S., it is now centered over the Rockies. Lower pressures are in the East. 

      This is an “ensemble” forecast map, meaning it’s the average of many separate runs of the same model. It tends to smooth things out, especially farther out it time. But for a forecast 9 days out, it’s a pretty obvious solution. Other computer model “ensembles”, including the world’s leading European model agree on this basic pattern. 


      It’s obviously too far out in time for a clear-cut, detailed forecast for 4th of July weekend. But……. 

      1. It will not be a “super-hot” weekend. Highs in the 90s are unlikely

      2. It will not be a “super-sunny” weekend. At least one of the days (Saturday, Sunday, Monday) should have more clouds than sun

      3. There should be at least some rain during that period.

      4. It’s unlikely to be a cool, “washout” weekend with a persistent east wind

      5. Any tropical system that develops in the Atlantic during the week would NOT be able to come up the East Coast. 

      It’s too early to get confidently more specific. That will come as we get closer to next weekend.

      <![CDATA[So, It Wasn't a Tsunami Off Jersey Shore, Delaware]]> Thu, 23 Jun 2016 13:20:04 -0400 http://media.nbcphiladelphia.com/images/192*120/Meteotsunami+Cape+May.JPG

      What the National Weather Service initially called a weather-related meteotsunami off the coast of the Jersey Shore and Delaware during severe storms Tuesday afternoon actually wasn't a tsunami after all because it didn't go far enough.

      "A meteotsunami, like all tsunamis, is a propagating wave train," said said U.S. NWS Pacific Tsunami Warning Center in a Facebook update. "While the sea-level anomaly shown in the figure did show up on other nearby tide gauges, it did not advance far beyond the mouth of Delaware Bay. In particular, it did not reflect from the shelf edge to come back to threaten the coast in the manner of the meteotsunami of June 2013. Since it did not propagate far, we cannot call the event a meteotsunami." [[383978851, C]]

      The peak of the event occurred right around 3:15 p.m. Eastern Standard Time and caused water levels to drop to around 0.5 meters, said the Honolulu, Hawaii-based Tsunami Warning Center.

      So what’s a meteotsunami?

      "A meteotsunami is generated when a high-speed straight-line windstorm (usually called a de recho) passes over shallow water," wrote the Tsunami Warning Center on Facebook. "The speed of a tsunami in deep water is hundreds of km per hour, but in shallow water it's much slower. If the water depth is 20 meters (as it is off the mouth of Delaware Bay), the tsunami speed is only 50 km/h. A low-pressure atmospheric system traveling at 50 km/h (or sustained winds of 50 km/h) can therefore kick up a "tsunami" (the process is called Proudman Resonance). So you can get a tsunami-like phenomenon generated not by an earthquake but by weather. We call these things meteotsunamis."

      A similar meteotsunami along the Jersey Coast in 2013 impacted coastlines up and down the East Coast.

      This time the incident, which the National Weather Service said was part of an "interesting" weather day, didn't make significant landfall.

      "The waveform in the figure may simply be the result of wind piling up water down Delaware Bay," said the NWS. "It clearly was a weather-induced long-wavelength phenomenon, but, unlike 2013, those waves were not the result of Proudman Resonance across the continental shelf (the atmospheric pressure record from Cape May shows a broad pressure pulse coincident with the waves rather than what was seen in 2013: a pressure pulse preceding the waves by more than an hour). The source area of this event appears to have been too small to sustain a tsunami; the waves rapidly dissipated."

      <![CDATA[Lesser Threat of Thunderstorms]]> Thu, 23 Jun 2016 07:43:05 -0400 http://media.nbcphiladelphia.com/images/213*120/Generic+Rain+Generic+Umbrella+Generic+Rainy.jpg

      After a sunny Wednesday the stormy weather returned Thursday but the worst of the storms will likely stay south of the Philadelphia region.

      "The further north you go the less likely these storms will be," said NBC10 First Alert Weather meteorologist Bill Henley. "This system has been trending to the southeast as high pressure moved in from the north."

      The rain moved into Philadelphia, the immediate suburbs, Delaware and South Jersey after 7 a.m.

      "This afternoon there's a chance for some scattered showers, there's a chance we'll see an evening thunderstorm but that's looking less likely now," said Bill.

      The threat for widespread hazardous weather was low, said the National Weather Service.

      Any heavy rain and thunderstorms will remain mainly south of the Philadelphia area during the morning commute.

      High temperatures will struggle to get into the low 80s for most of the area Thursday.

      Once the rain moves out, we’re in for lovely weather again with a sunny and dry Friday with highs in the mid-80s. Temperatures will rise over the weekend with highs in the 90s and sunny and dry conditions once again.

      "We're looking good through the weekend," Bill said. "Nice at the shore" with temps in the 70s Friday before pushing into the 80s Saturday and Sunday.

      <![CDATA[Possible Tornado, Severe Storms Slam NJ, Del. ]]> Wed, 22 Jun 2016 12:10:42 -0400 http://media.nbcphiladelphia.com/images/213*120/WildwoodStorm.jpg

      Severe storms, lightning, wind and a possible tornado slammed South Jersey and Delaware Tuesday, toppling trees, damaging buildings and leaving thousands in the dark.

      The National Weather Service issued a Tornado Warning for Cape May County, New Jersey Tuesday afternoon. At 3:39 p.m., a severe thunderstorm capable of producing a tornado was located over Green Creek, about eight miles north of Cape May, and moved east at 45 mph. The storm moved into Stone Harbor around 3:45 p.m. and Avalon around 3:50 p.m. The Warning was canceled shortly after 4 p.m.

      The storms caused widespread power outages, nearing 39,000 at one point. As of midday Wednesday, about 5,000 customers remained without power in Cape May County. Officials say the most impacted areas by the storm were Lower Township, southern Middle Township and parts of Wildwood. They also said about a dozen homes were damaged.

      The powerful winds tore off the roof of the public works building in Wildwood, New Jersey during the storm. Several trees also fell in the parking lot of a Home Depot on Indian Trail Road in Middle Township.

      "[It was] very loud," said Kristin Jost, the store manager. "Some crashing. Outside the window you could see some lightning."

      The winds knocked three heating and AC units out of place on the roof of the store, causing water to leak through. All of the customers got out safely and the store closed early.

      "[We] gave them some water and really just worked on calming everybody down," Jost said. 

      A large tree also crashed through the Middle Township home of Chris Vasser during the storm. Vasser, who wasn't home at the time, was relieved to find out his two cats were safe.

      "That's all I need," Vasser said. "Thank you Lord."

      Vasser's neighbor, Bonnie Marks, told NBC10 she was there when the violent storm rolled through.

      "It was like a tornado was coming down the street," Marks said. "A big wssssh! I was literally standing there shaking."

      NBC10 First Alert Weather producer David Parkinson said a tornado may have touched down in Middle Township's Burleigh community though it has not yet been confirmed.

      Despite all the damage, no injuries were reported.

      Prior to the Tornado Warning, the NBC10 First Alert Weather Team issued a First Alert Weather Day due to severe thunderstorms that slammed Delaware and South Jersey with winds near 70 mph, lightning, heavy rain and hail.

      Another line of storms moved into parts of Bucks, Mercer, Sussex and Kent counties Tuesday night. A Severe Thunderstorm Watch was in effect for all of Delaware as well as Cumberland, Salem and Cape May counties but was later canceled around 10 p.m.

      Conditions should clear overnight leading to a sunny and warm Wednesday with highs in the upper 80s.

      <![CDATA[Summer Brings Second Heat Wave]]> Mon, 20 Jun 2016 20:14:50 -0400 http://media.nbcphiladelphia.com/images/213*120/Philly+Hot+Sun_19898880.jpg


      Summer officially begins at 6:34 PM on Monday. Tuesday will be the longest day of the year with a glorious 15 hours and 1 minute of daylight. Tuesday also kicks off a two week stretch of the latest sunsets of the year, at 8:33 PM. The sun will start setting earlier after July 6th. 

      It certainly feels like summer out. Monday is the second straight day above 90 degrees in Philadelphia. One more makes it a heat wave, which is defined as three straight days of 90 degrees or more. We should get there on Tuesday. We’re forecasting 90 in Philadelphia. 


      Better than 2/3 of the country is roasting in sweltering temperatures now. Phoenix hit 118 degrees on Sunday, and our sister station in Los Angeles is forecasting 110 degrees in Burbank on Monday. It’s all thanks to a giant High Pressure system located in Utah and a giant ridge in the jet stream that is bringing hot air all the way up to Canada. Fortunately, those ridges can’t live very long and we’ll start cooling down thanks to a backdoor front on Wednesday.

      [[383679491, C]]


      As we summer begins, don’t forget we’ve already had a heat wave in Philadelphia. That heat wave happened in May! Unfortunately, we’re looking at a hot summer this year. The Climate Prediction Center is giving us a 50% chance for an above average July, August and September, so make sure you’ve got good air-conditioning set up for the summer.
