Latest Forecast

A warm front lifting northeastward through the Commonwealth will be the focal point for a few showers this afternoon. However, most areas should remain dry with high temperatures in the low-to-mid 80s and dewpoints around 70°F. Behind the warm front, west-southwesterly winds will usher unseasonably hot and even muggier air into northern MD and southeastern PA on Tuesday. High temperatures will be in the low-to-mid 90s with dewpoints in the low 70s. As a result, heat indices will peak around 100°F Tuesday afternoon. Drink plenty of non-alcoholic beverages and take frequent breaks in an air-conditioned room or building to stay hydrated and cool. A pair of disturbances diving southeastward from the eastern Great Lakes region through northern PA and southern New England may trigger isolated showers and thunderstorms from Tuesday afternoon through Wednesday, but most of the activity should remain north of the Lower Susquehanna Valley. However, any storms that do reach south-central PA will produce locally damaging wind gusts, torrential downpours, hail and frequent lightning.
