Latest Forecast

An area of high pressure over the central Appalachians and mid-Atlantic States will promote mostly sunny skies, light winds and seasonably warm conditions this afternoon. The high pressure system will shift into the western Atlantic on Saturday, and southerly winds on its backside will boost high temperatures into the upper 80s to perhaps 90 degrees Saturday afternoon. Skies will then turn mostly cloudy Saturday night into Sunday ahead of a slow-moving storm system, but showers and thunderstorms should not reach northern MD and southeastern PA until Sunday evening. The southerly flow will also strengthen on Sunday and pump more humid air into the Lower Susquehanna Valley with dewpoints back in the upper 60s.
