Weather Authority: Overnight temperatures cool down in wake of strong storms

PHILADELPHIA - Cooler temperatures will follow in the wake of powerful thunderstorms that brought strong winds and heavy downpours to the region Monday. 

Forecasters warned of strong thunderstorms on Monday with wind gusts upwards of 70 MPH that some feared could spin up an isolated tornado. The National Weather Service issued a region-wide Severe Thunderstorm Watch that was upgraded to a warning in some areas of Pennsylvania. 

The brunt of the storms rolled across the Lehigh Valley in the early evening and continued into New York and parts of New England. The severe weather threat across the Delaware Valley expired at 9 p.m.

As the storms continue northeast and offshore, FOX 29's Kathy Orr says colder air with drop temperatures into the upper 50s overnight. Sunshine will return Tuesday, but gusty winds will remain with highs hovering around the 70s. 

An unseasonably cold Wednesday will be followed by a meaningful rise in temperature that will continue into the weekend. Temperatures will climb into the mid-80s on Friday and reach into the 90s over the weekend.
