Latest Forecast

A storm system moving eastward through the mid-Atlantic States will trigger scattered strong-to-severe thunderstorms across northern MD, southeastern PA and the Lower Susquehanna Valley between 2-8 PM. Damaging wind gusts up to 65 mph, frequent lightning and torrential downpours will be the main threats from the storms, but an isolated tornado or two cannot be ruled out. Have multiple ways to receive severe weather alerts this afternoon, and seek shelter in an interior room or basement if a warning is issued for your location. Downed trees and power lines, as well as isolated power outages and roof damage, are all expected in the hardest-hit areas. Storms should push south/east of the I-95 corridor during the mid-to-late evening hours, but mostly cloudy skies and a few showers may linger overnight into Tuesday morning. Behind the system, north-northwesterly winds of 10-20 mph will usher cooler and drier air into the region Tuesday afternoon. As a result, skies should gradually clear, and the air will turn less humid with dewpoints back down in the upper 50s. An area of high pressure will then settle into the Commonwealth from Tuesday night into Wednesday and promote mainly clear skies, low humidity and comfortable conditions.
