Severe storms are predicted to hit the area this afternoon, followed by Philadelphia’s first heat wave of the summer.
The National Weather Service issued a heat advisory for Thursday, June 19, until 8 p.m. in Philadelphia and Delaware counties.
According to The Weather Channel, Philadelphia is forecasted to experience temperatures upwards of 85 degrees over the next seven days.
The hottest day is expected to be Tuesday, June 24, with a high of 101 degrees and a low of 80 degrees. This would mark the hottest day of 2025 so far. The highest temperature Philadelphia has reached this year as of June 19, was a 92 degrees on June 12, according to the National Weather Service.
Philadelphia’s extreme heat is due to the warm front approaching the city as people prepare for the weekend.
Warm fronts typically move from the southwest region of the United States to the northeast bringing warm, moist air to the region replacing cooler air. Heat brought by warm fronts creates a high possibility of thunderstorms as the less dense, warm air near the ground rises, water vapor condenses and it builds onto existing clouds.
There is a moderate risk for damaging winds and severe storms to continue to develop as the heat progresses. While tornadoes are not expected, they “cannot be ruled out,” the Weather Channel said.
The city reminds Philadelphians to visit cooling centers, pools, or spraygrounds. Local cooling centers stay open later during excessive heat. In the event of heat emergencies, mobile heat health teams may be dispatched and shut offs of residential utility stop.
During a heat health emergency, call the Heatline at 215-765-9040. Nurses will answer questions about health and heat-related illnesses through the Heatline.
