System To Bring Severe Storms, Hail And Even Snow To PA

>>>Updated Forecast, Timeline For Wednesday Storms In PA

PENNSYLVANIA — The possibility of severe weather is in the forecast Wednesday ahead of a cold snap that could bring near-record lows and even some snow to parts of Pennsylvania.

Severe thunderstorms are in the forecast for Eastern Pennsylvania in the afternoon and early evening Wednesday. AccuWeather reports the storm's most significant threat to the region is dangerous lightning and damaging wind gusts.

Some of the storms could bring small hail, as well as torrential downpours that could lead to ponding on roadways and in areas with poor drainage.

"The collision with the warm air lingering along the East Coast early on Wednesday and the fresh push of cold Arctic air, will help create an unstable enough environment for thunderstorms on Wednesday," said AccuWeather Senior Meteorologist Paul Walker.

Some parts of northwestern Pennsylvania could even get some snow Wednesday, according to forecasters. Accumulation is not expected to be significant. About 1 to 3 inches is predicted in Erie, The National Weather Service said.

Once the storms move through, expect chillier conditions.

Temperatures are expected to be between 10 and 20 degrees below normal from Wednesday to Friday, AccuWeather said.
