Regional Weather Summary
National Weather Service State College PA
1055 PM EDT Mon Jun 29 2026

Heat and humidity will build over western Pennsylvania on Tuesday
and expand throughout much of the Commonwealth by Wednesday. This
heat and humidity will peak on Thursday and Friday across the 
Commonwealth with heat index values over 100 degrees across much 
of the area. A corridor of heat index values exceeding 105 degrees
will be possible across portions of eastern Pennsylvania, where 
an Extreme Heat Watch is in effect. Low temperatures in this 
timeframe will allow for little relief from this heat later this 
week, with temperatures beginning to downtrend by the second half 
of the weekend.

Showers and thunderstorms will be possible on Tuesday, especially
across the northern tier of Pennsylvania along with higher 
elevation locations where a stray shower could pop up. Dry 
conditions are expected for most on Wednesday and Thursday, with 
the next chance for more widespread showers and thunderstorms 
possible on Friday and continuing into the weekend.

Stay informed and take steps to protect yourself from heat 
related illness. Drink plenty of fluids and refrain from doing any
strenuous activity in the sun during the peak heat of the day.
