Latest Forecast

An area of high pressure over the central Appalachians and southern mid-Atlantic states will promote mainly clear and cold conditions across the Lower Susquehanna Valley tonight with low temperatures in the low-to-mid 20s. A cold front will then sweep through the Commonwealth on Thursday, but only a few stray flurries will accompany its passage. Behind the front, northwesterly winds of 12-25 mph with gusts up to 35 mph will usher a reinforcing shot of Arctic air into the region Thursday night. Under mainly clear skies, temperatures will plummet into the low-to-mid teens early Friday morning. Skies will then turn mostly cloudy on Friday, and light snow may graze northern MD and southeastern PA Friday afternoon as a weak storm system zips through the Carolinas. However, the snow could just as easily stay south of the region. The weekend will start on a partly sunny and cold note with highs near 40.
