PHILADELPHIA - Cooler temperatures will follow in the wake of a powerful storm system that plowed across the Delaware Valley Thursday night, bringing severe weather advisories and a brief isolated tornado warning.
Thursday night was a preview of what normally happens during the warm summer months. Daytime highs reached into the 70s that helped make the conditions right for an incoming cold front that pushed a line of storms across the area.
The National Weather Service first issued a region wide Severe Thunderstorm Watch which was later upgraded to a warning in parts of the region.
Winds that gusted up to 60 MPH helped spin up a brief Tornado Warning in central Bucks County. Forecasters said the storm system weakened as it moved across New Jersey towards the shore to help end the severe weather threat.
