When Will Rain Stop? Here's The Latest On Cross-Country Storm Drenching PA

EASTERN PA — Heavy rain and thunderstorms will hit the greater Philadelphia area over the coming days, potentially bringing damaging winds and flooding to parts of the region, according to forecasters.

It's part of the remnants of a severe cross-country storm bearing potential tornadoes and 80 mile an hour wind gusts across the midwest, Accuweather says. The greater Philadelphia area, however, along with much of the east coast, is likely to only see less severe effects.

Still, the accumulated rainfall could cause travel delays, and a coastal flood advisory has been issued for parts of the Delaware River watershed, including in Philadelphia, lower Bucks, and Delaware counties.

As for timing, forecasters say that intermittent rain and thunder will continue from Wednesday afternoon through Saturday night, before the front finally clears on Sunday. While showers may be heavy at times, they're also expected to be scattered. Several hours of rainfall could be frequently punctuated by several hours of dry and still conditions.

"The old storm (from the midwest) will still trigger a band of steady rain from the upper mid-Atlantic to southwestern New England into Wednesday evening, with New York City at the center of the wet conditions," Accuweather says. "Enough rain can fall to lead to flash urban flooding and slow travel due to ponding on some roads."

Accumulated rainfall totals are forecasted to be about a tenth of an inch on Wednesday, Thursday, and Friday, with higher amounts expected in the midst of thunderstorms.

"At this level, flooding begins on the most vulnerable roads along tidal waterways. Some partial or full road closures are possible," the National Weather Service said. "Minor coastal flooding is forecast with the overnight high tides Thursday night and Friday night as well, especially along the upper reaches of the tidal Delaware River."

Temperatures will remain summer-like through much of the storm, with highs in the low 80s and upper 70s for most of the week and into the weekend. The expected pauses in the storm could bring a tropical feeling to the air, with the heat combined with lingering humidity.
