Regional Weather Summary
National Weather Service State College PA
455 PM EDT Mon May 18 2026

Scattered showers and thunderstorms will remain possible this 
evening, mainly across south-central Pennsylvania. Some of these 
storms could become strong-to-severe and produce damaging wind 
gusts before weakening a couple of hours after sunset. Most of the
Commonwealth will remain dry overnight after shower/storm 
activity diminishes with any precipitation limited to the 
northwestern corner of the state closer to daybreak on Tuesday. 
Low temperatures overnight will range from the mid-60s across the 
northern tier to near 70 across far southeastern Pennsylvania. 

Another day of potentially record heat is on tap for Tuesday, 
with high temperatures ranging from the lower 80s across higher 
elevations of northern Pennsylvania to the upper 90s in the 
Philadelphia metro area. Morning shower activity will be limited 
to northwestern Pennsylvania with showers and storms expected to 
expand across the western half of the Commonwealth by the evening 
hours. Some strong-to-severe thunderstorms will be possible 
tomorrow evening, especially across northwestern Pennsylvania, 
with damaging winds being the main hazard.

A strong cold front will bring showers and scattered storms on 
Wednesday, some of which could be severe in the afternoon and 
early evening across the southeastern half of the state. Cooler, 
more seasonable conditions will follow for the end of the week and
into Memorial Day weekend.
