Storms are projected to commence late Tuesday afternoon, peaking between 4 p.m. and 8 p.m. As the cold front moves in, it will usher cooler air and increase atmospheric instability, triggering scattered thunderstorms.

End of Heatwave: Cooler Weather Expected Midweek
Following several days of oppressive heat, the Philadelphia area is set to experience a significant weather shift. The incoming storm system on Tuesday afternoon will bring scattered thunderstorms and showers, effectively breaking the recent heatwave that saw temperatures soar above 90°F for much of the past week. While these storms may cause temporary inconveniences such as brief power interruptions and localized flooding, they are a welcome change for many.
After the storm passes, a weakening high-pressure system will allow cooler air to flow in from the north, dropping temperatures by approximately 10 degrees by midweek. This shift will usher in more comfortable conditions for the remainder of the week. Here’s a snapshot of the upcoming weather:
- Tuesday: Scattered thunderstorms, highs near 88°F

| Thursday | 75 | 10% | Sunny and Cooler |
