Latest Forecast

A vigorous disturbance will track northeastward through the Commonwealth and Delmarva Region tonight into Sunday morning, bringing periods of rain and thunderstorms to the region. Most areas will receive 0.50-1.00" of rain from the system, with locally higher amounts up to 2". The heavy rainfall may result in localized flooding and ponding on roadways this evening into tonight. Behind the disturbance, skies will gradually clear during the late-morning to midday hours on Sunday, however, warm and muggy conditions will persist Sunday afternoon with high temperatures around 5 degrees above normal, and dewpoints in the upper 60s. A cold front will sweep through northern MD and southeastern PA Sunday night into Monday morning, bringing a chance for a few passing showers. In its wake, northernly winds of 10-20 mph will usher much cooler and drier air into the Lower Susquehanna Valley. As a result, Monday will turn out mostly sunny and breezy with highs in the mid-to-upper 70s. An area of high pressure will approach the region on Tuesday, which will continue pleasant and seasonable conditions across the area.
