Weather Authority: Storms with heavy downpours, strong winds set to move across the region Tuesday night

PHILADELPHIA - A stretch of late-summer heat will be thwarted on Tuesday night when a cold front will push strong storms across the Delaware Valley, according to forecasters. 

The chance for rain is expected to increase after 5 p.m. Tuesday. 

The storms are set to include severe conditions, including heavy downpours, thunderstorms and strong winds. 

Temperatures are set to drop Wednesday after the storms before they return to the 90s by Saturday. 

Looking ahead, FOX 29's Sue Serio has the forecast for this weekend's Made In America Festival. She says conditions will be hot and humid with some late storms expected Sunday night.
