Philadelphia, PA – Scattered thunderstorms may disrupt Saturday plans in eastern Pennsylvania, as humid air and afternoon instability trigger downpours after 2 p.m.
According to the National Weather Service, a slight chance of showers and storms begins late morning, increasing to likely storms by mid-afternoon. Rainfall may total less than a tenth of an inch, but higher amounts are possible in stronger thunderstorms, especially in the I-76 corridor and central Philadelphia.
Conditions will remain muggy with highs near 90°F, and calm morning winds will shift from the south around 5 mph. Drivers should expect reduced visibility during heavier cells and slowdowns on regional roadways like I-95 and the Schuylkill Expressway. If thunder roars, move indoors — lightning is a primary hazard.
Skies clear by Saturday night, setting up a sunny and less humid Sunday with highs around 90°F. Monday brings a renewed storm risk, with a 50% chance of afternoon thunderstorms. Temperatures will remain in the upper 80s and low 90s through early next week.
Stay weather-aware this weekend by enabling alerts and checking local radar. The next weather update is expected early Sunday morning.
