Latest Forecast

After a mostly sunny, hot and humid Wednesday morning, clouds will increase early this afternoon in advance of a potent cold front. Scattered showers and thunderstorms will then erupt along and just ahead of the front between 2-10 PM. The most intense storms will produce frequent lightning, torrential downpours, small hail and damaging wind gusts up to 60 mph. Isolated incidents of downed trees and powerlines, as well as some power outages, are expected. Motorists should be alert for areas of reduced visibility, as well as standing water and debris on some roadways, during the PM commute. Prior to the storms' arrival, high temperatures should still reach or exceed the 90-degree mark across most of northern MD and southeastern PA, making this the first official heatwave of 2026. The cold front will briefly stall across the southern mid-Atlantic States later tonight into Thursday, and a weak wave of low pressure moving northeastward along it will bring additional showers and periods of light rain to the Lower Susquehanna Valley on Thursday. Behind the front, north-northeasterly winds will usher much cooler air into the region on Thursday, as well, and high temperatures will actually end up around 10-15°F below average Thursday afternoon under cloudy skies. The rain should taper off from west-to-east Thursday afternoon but, after a mostly cloudy and dry Thursday night and Friday morning, return Friday afternoon as the boundary lifts back northward as a warm front. Due to the clouds and wet weather, high temperatures on Friday will be similar to Thursday.
