First heat wave of 2024 looking likely 🌡️
The heat keeps building this workweek with highs in the low 90s Tuesday and feeling like to mid 90s or hotter.
The high on Wednesday gets into the low 90s, but not as humid. It will be feeling like the mid 90s Thursday. The National Weather service issued a heat advisory for the next few days.

Then changes come in a big way heading into the weekend as heat and humidity ramp up Friday, Saturday and Sunday with feels-like temps of 99 to 104 degrees. Temps could near records (or even break them) this weekend as an excessive heat watch is in effect through the weekend.
Feels-like temps on Saturday will push near or past triple digits in many neighborhoods.

Sunday is then shaping up to be the steamiest day with brutal feels-like temps approaching 105 degrees. The high on Sunday in Philadelphia is expected to be 98, which would break a record that dates back to the 1880s.
The only places where you will get relief from the heat (besides being in air conditioned space) is at the Jersey Shore.
Isolated storms are possible later on Friday, Saturday and Sunday, but aren't expected to break the heat.

High temps must hit 90 degrees or higher for three straight days for a heat wave to be declared.

The 90s are expected to continue well into the following week. Should the temp get to 90 on Monday, June 24, the heat wave should extend through all of next workweek.

Tips for dealing with heat, noticing signs of heat-related illness
The expected heat wave may last for the entire week and could lead to dangerous health conditions with little relief offered. Be sure to limit time exerting yourself outside, especially during the hottest parts of the day.
Ready.gov shares these heat tips:
- Never leave people or pets in a closed car on a warm day.
- If air conditioning is not available in your home go to a cooling center.
- Take cool showers or baths.
- Wear loose, lightweight, light-colored clothing.
- Use your oven less to help reduce the temperature in your home.
- If you’re outside, find shade. Wear a hat wide enough to protect your face.
- Drink plenty of fluids to stay hydrated.
- Avoid high-energy activities or work outdoors during midday heat, if possible.
- Check on family members, older adults and neighbors.
- Watch for heat cramps, heat exhaustion and heat stroke.
- Consider pet safety. If they are outside, make sure they have plenty of cool water and access to comfortable shade. Asphalt and dark pavement can be very hot on your pet’s feet.

Also, be aware of the signs of heat-related illnesses. A body temperature of 103 degrees or higher; red, hot and dry skin without sweat; a rapid, strong pulse; and dizziness, confusion or unconsciousness can all be signs of heat stroke.
Should you or a loved one have any of these symptoms, call 911 or go to the hospital immediately.
