A First Alert for Monday as we undergo big changes in the next few days.
Take a look at the surface map from the Weather Prediction Center. The front will bring periods of rain, high winds, and a change in high temperatures. Let’s break down the timeline
Monday temperatures will still be warmer than average, in the low- to mid-70s during the afternoon. Mostly cloudy conditions will prevail, and isolated showers are possible. The shower potential is low, and mostly focused over north and west neighborhoods. Humidity will be higher, too.
For those going to the Eagles game Monday night, temperatures will sit in the upper 60s by the 8:30 p.m. kickoff. Winds will be breezy to windy, with gusts between 25 and 30 mph. Spotty showers are possible by the second half of the game.
The cold front will approach the region early Tuesday. By 2 a.m., some steadier rain may begin to fall, extending west to east.
During the morning commute Tuesday, some pockets of heavier rain and isolated thunderstorms are possible leading to the First Alert.
This trend continues into the afternoon: periods of heavy rain with some thunderstorm developing.
By late afternoon and into the early evening, the front will begin to exit the region. Some rain and thunderstorms may linger against the shoreline overnight and even into Wednesday morning.
There is a “slight” chance of severe storm development Tuesday. This means while it isn’t likely to be widespread, an isolated to scattered thunderstorm may become dangerous. These storms have the potential to pack damaging winds, lightning or hail. They can even spur a small tornado.
Periods of heavy rain are likely. Totals will range between 0.75 inches and 1.5 inches. Here’s a look at one computer model called the GFS (the American Model). Many models are similar in projected totals.
Wind gusts will kick up with the system. Beginning Monday night through Tuesday evening, the winds will knock the region. The strongest gusts will hit during the day Tuesday. Gusts will pick up between 35 and 45 mph. Pull in anything from the back or front yard that may blow around.
Another concern? Localized flooding is possible thanks to leaves that can clog storm drains. Check your neighborhood drains Monday evening to be sure roads near you don’t collect rain water. Leaves can also be slippery when wet, leading to a walking hazard Tuesday.
Once the front passes, temperatures will sink. Wednesday afternoon the forecasted high is only 65 degrees. The region will begin to clear out late Wednesday as well. More sun is likely Thursday and Friday. The highs remain in the 60s through the weekend, when another round of rain is possible. More updates on that in the days to come!
