Latest Forecast

A trough, or dip in the Jet Stream, over the Northeast will promote partly-to-mostly sunny skies, low humidity and pleasant conditions across the Lower Susquehanna Valley today. High temperatures will be several degrees below normal this afternoon, and the weather will be perfect for sleeping with the windows open again tonight! An area of high pressure will then settle into the mid-Atlantic States on Wednesday, and a light, southerly breeze should usher warmer and more seasonable air back into the Commonwealth. Humidity will increase dramatically Wednesday night, and scattered showers and thunderstorms are then expected to erupt on Thursday well in advance of a cold front. The worst storms will likely occur Thursday afternoon and produce frequent lightning, blinding downpours and wind gusts up to 50 mph.
