Short but heavy rainstorms passed through Philadelphia and most of the surrounding area Thursday afternoon, but that was just the first wave from a weather system expected to impact the region Thursday night and into Friday morning.
The National Weather Service's office in Mt. Holly, New Jersey, has issued a severe thunderstorm watch for Philadelphia, Delaware, Chester, Montgomery and Berks counties in Pennsylvania. The watch remains in effect until midnight Friday.
A similar storm watch has been issued in New Jersey for all South Jersey and Jersey Shore counties.
At about 2:15 p.m. Thursday, the National Weather Service's office in Mt. Holly, New Jersey, had issued a severe thunderstorm warning for Philadelphia; portions of Delaware County in Pennsylvania; and portions of Camden, Burlington and Gloucester counties in South Jersey.
NWS meteorologists forecast "torrential" rain, impacting much of the region that may lead to flash flooding.
In addition to the NWS's severe thunder storm watch, a flash flood watch is in effect until Friday morning in northern Delaware; South Jersey and the Jersey Shore; and Chester, Delaware, Bucks, Montgomery, Berks and Philadelphia counties in Pennsylvania.
The rain will end a string of 90-plus-degree days across the Delaware Valley. Friday's high temperature is expected to be near 84 degrees.
