Latest Forecast

A trough, or dip in the Jet Stream, over the Eastern United States will promote unseasonably cold weather through the end of the week. A Canadian high pressure system over the Ohio Valley will bring mostly sunny and dry conditions to the Lower Susquehanna Valley through Thursday. Despite the sunshine, temperatures will be around 5-10 degrees below average both days. After a partly cloudy and cold Thursday night, a clipper system and its associated Arctic cold front will bring snow showers or intermittent, light snow to the Commonwealth on Friday. Snow accumulations of a coating to 2" are expected across northern MD and southeastern PA. Pre-treated and primary roads will generally be wet during the Friday afternoon commute with high temperatures near 30°F. There may be a few slick/slushy spots on secondary roads, but impacts to travel should be minimal. In the wake of the system, winds will pickup Friday evening and continue into Saturday with sustained winds of 20-30mph and some gusts over 40mph. Accompanying the wind, Saturday will bring mostly sunny and unseasonably cold conditions.
