Severe Thunderstorms, Fierce Winds, Hail Possible In PA: See Forecast

PENNSYLVANIA - Thunderstorms, heavy rain, gusty winds and hot temperatures are all in store for Pennsylvanians ahead of the long Memorial Day weekend, forecasters said.

Though Wednesday will begin with sunny skies and temperatures in the mid-80s, isolated to scattered showers and thunderstorms could develop as early as late Wednesday afternoon and evening, the National Weather Service said. Locally gusty winds and small hail possible as temperatures drop to the mid-60s overnight.

Though a few showers and thunder is possible Thursday morning, “more numerous” thunderstorms and heavy rain are set to develop later Thursday as temperatures approach the mid-80s again, the weather service added. The early evening storms will prove to be the strongest, with gusty winds and more hail in the forecast.

Flooding isn’t off the table for regions with poor drainage, AccuWeather noted.
