Regional Weather Summary
National Weather Service State College PA
324 AM EDT Tue May 23 2017

High clouds were across much of the Keystone state early 
this morning. Patchy dense fog was across portions of 
eastern Pennsylvania. Early morning temperatures were
mainly in the 50s but in the 40s across the northern 
mountains. 

The fog will quickly burn off shortly after sunrise. 
Much of the day will feature high clouds, with just a 
small chance of some very light rain along the Maryland border 
toward late afternoon. High temperatures will be mainly in the 
lower to mid 70s, but in the upper 60s across the southwest. 

There will still be a slight chance of some light rain this 
evening into early Wednesday morning across the far south. 
Lows tonight will range from the upper 40s across the mountains, 
to the lower to mid 50s across the rest of the Keystone state.

Highs on Wednesday will be similar to today. Rain will 
overspread western sections of central Pennsylvania during
the afternoon hours, as a complex area of low pressure 
forms across the Tennessee Valley. A soaking rain is 
expected across the region Wednesday Night into Friday 
morning. After some near normal temperatures today and 
Wednesday, below normal temperatures are expected to occur 
Thursday into Friday. At this point, it looks like 
temperatures will recover to more normal levels for 
the upcoming holiday weekend.
