Regional Weather Summary
National Weather Service State College PA
536 AM EDT Thu Aug 21 2025

A deep east to northeast flow of moisture off the Northern
Atlantic will lead to another unseasonably cool day across the
eastern half of the state with plenty of thick clouds and little
or no sunshine. Expect nothing more than some patchy light
drizzle this morning, with just a light ground wetting possible
in a few spots.

High temperatures this afternoon will once again range from the
upper 60s over the Mountains to the north and east of Williamsport
to around 80 in the Greater Pittsburgh area.

Gradual clearing from north to south will occur later tonight and
early Friday as a ridge of high pressure drifts south toward the
Commonwealth. Lows early Friday morning will vary from the Upper
40s and low 50s across the Northern Tier Counties of Pennsylvania
to the low 60s in the southwest corner of the state.

Warmer conditions with plenty of sunshine and low humidity is
expected Friday and Saturday. A round of showers and potentially
strong thunderstorms will follow on Sunday. A substantial cool
down with fall- like conditions is poised to arrive next week.
