Incoming Storms Prompt Hazardous Weather Outlook For Eastern PA

PHILADELPHIA, PA — Stormy weather is headed to the Philadelphia region to finish out the week. This next round of storms could lead to flash flooding after the Memorial Day Weekend weather left the ground saturated, forecasters say.

The National Weather Service has issued a Hazardous Weather Outlook for the region in advance of the incoming storms.

Forecasters predict Thursday could start off with showers. There's a chance of thunderstorms in the afternoon into the evening.

"Some of the storms could produce heavy rainfall," the National Weather Service said. The chance of precipitation Thursday is 70 percent. New rainfall amounts of between a quarter and a half inch are possible that day.

The chance of thunderstorms continues overnight Thursday into Friday. Again during this timeframe, some of the storms could produce heavy rainfall. There is a 90 percent chance of precipitation Thursday night, with new rainfall amounts between a quarter and half inch possible.

The rain is expected to continue Friday, with thunderstorms also possible after 2 p.m.

Scattered showers and thunderstorms could linger up until around 8 p.m. Friday, then isolated showers are possible between 8 p.m. and 2 a.m.

The two-day wet streak could bring a flash flooding risk.

"The risk of flash flooding is a bit higher than average at this point for the parts of the central Appalachians, mid-Atlantic and southern New England, where the bulk of the rain from last weekend's storm occurred," AccuWeather Senior Meteorologist Dave Dombek said.

AccuWeather predicts Thursday will be the wettest day overall. "Motorists should expect slowdowns on the highways due to the downpours," forecasters said in a news release.

Things should clear by Saturday. Sunny skies and temperatures in the upper 80s are predicted to start off the weekend.
