Latest Forecast

A sprawling high pressure system over the Northeast will promote mostly sunny skies, low humidity, and pleasantly warm conditions this afternoon. The high will then shift into the western Atlantic on Friday night and Saturday. On its backside, southerly winds will draw warmer and more humid air back into the mid-Atlantic States. Dewpoints will surge into the 70s Saturday afternoon with high temperatures in the mid-to-upper 80s despite significant cloud cover. Additionally, isolated showers and thunderstorms should return late Saturday afternoon well in advance of the next cold front. The storms will become more widespread Saturday night and produce locally heavy downpours. Damaging wind gusts up to 60 mph are also possible in spots, mainly north/west of I-81. The cold front will traverse northern MD, southeastern PA, and the Lower Susquehanna Valley from west-to-east on Sunday and trigger another round of showers and storms. Severe weather should be confined to areas near and south/east of the I-95 corridor. Ahead of the front, another hot and humid day is expected with highs in the low 90s and heat indices in the mid-to-upper 90s.
