Latest Forecast

South-southwesterly winds of 8-16 mph on the backside of a high pressure system will usher warmer and more humid air into northern MD and southeastern PA today. Under mostly sunny skies, high temperatures will soar into the low-to-mid 80s with dewpoints in the mid 60s. The unseasonably warm and humid air mass will remain in place on Wednesday, and the October 14th record high temperature of 84 degrees from 1975 at Millersville University may be challenged or tied. A weak cold front will sag southward through the Commonwealth Wednesday afternoon into Wednesday night and spark isolated showers across the Lower Susquehanna Valley. Most areas should remain dry, but the heaviest showers could produce brief downpours and a rumble of thunder. Behind the front, northeasterly winds will usher much cooler and drier air into the region on Thursday. High temperatures should be around 15 degrees lower than Wednesday and back down around average under partly-to-mostly cloudy skies.
