Latest Forecast
A deep trough, or dip in the Jet Stream, over the Northeast will promote unseasonably cold conditions across the Lower Susquehanna Valley early this week. High temperatures this afternoon will be around 15 degrees below average, and wind chills will be stuck in the single digits and teens due to northwesterly winds of 10-20 mph. An area of high pressure will settle into the Carolinas and southern mid-Atlantic States from tonight into Tuesday and cause winds to subside. However, temperatures will remain around 10 degrees below average Tuesday afternoon despite mostly sunny skies. Dress in layers and bundle up before heading outside early this week! The high pressure system will then shift into the western Atlantic on Wednesday. On its backside, southwesterly winds will finally usher milder and more seasonable air into northern MD and southeastern PA.
