Friday Storms Likely Start To Cooler, Wet Weekend In PA

Severe thunderstorms could rattle the Philadelphia region this weekend, beginning on Friday evening. The National Weather Service has issued a hazardous weather outlook for some of Eastern Pennsylvania, saying there is a chance for severe thunderstorms Friday evening and into the night.

AccuWeather is warning of damaging thunderstorms and gusty winds across the region. Meteorologists with that network say the system will "speed through the Northeast" on Friday evening.

The storms will bring some cooler air to the region, and could also result in high winds, forecasters predict. Damage to trees and power lines is possible, as well as hail, according to AccuWeather.

According to the NWS, the northeast should brace for storms that will be followed by a cold front. On Friday, temperatures across the area are as much as 25 degreeshigher than average. By Saturday, due to the cold front, temperatures will be closer to average for early May, the NWS said.

Here is the National Weather Service's map showing where a hazardous weather outlook is currently in place:

The risk of flash flooding will be limited to a localized level given the quick-moving nature of the overall storm system. “The severity of the thunderstorms is expected to lessen prior to reaching the I-95 corridor,” AccuWeather Senior Meteorologist Kristina Pydynowski said in a news release.
