Rain Threatens Philly Area Labor Day Weekend Forecast: See Timeline

EASTERN PA — An at least somewhat rainy Labor Day weekend appears to be on tap for the greater Philadelphia area, with several chances for storms to impact the region, according to forecasters.

However, most of the storm fronts are not anticipated to be severe, and there is also a good chance some of the rain will miss the city and the five county suburban region.

The first chance for rain is Thursday night, with a slight possibility of precipitation and thunderstorms after 2 a.m.

The chance for storms will continue overnight until around 8 a.m., when the thunder will vanish but a slight chance of rain — around 20 percent, the National Weather Service says — will persist until around 2 p.m.

Friday night will be cloudy and without rain, but storms will return Saturday afternoon, with a 30 chance of showers between 2 p.m. and 5 p.m. and a chance of thunderstorms into the evening. Still, only a tenth of an inch of rain is expected.

Saturday night will be the most significant rainfall of the weekend, with showers and thunderstorms likely after 8 p.m. and until around 2 p.m. Up to half an inch of rain could fall.

Rain will peter off by later Sunday morning at the latest and leave the region mostly clear by Sunday night. Monday is forecasted to be early autumn-like, with sunny skies and a high of 81.
