Latest Forecast

Broad, southwesterly flow will continue to pump very hot and humid air into the Lower Susquehanna Valley through Tuesday. High temperatures both this afternoon and tomorrow will reach the low-to- mid 90s with heat indices as high as 103°F in urban areas. Drink plenty of non-alcoholic beverages, take frequent breaks from the heat in an air-conditioned room or building, and wear lightweight clothing if you have prolonged outdoor plans. A cold front sagging slowly southward through the Commonwealth will cause scattered showers and thunderstorms to erupt Tuesday afternoon and evening. The cold front will temporarily stall out near the Mason-Dixon Line on Wednesday, triggering a second round of showers and storms. Although severe weather is not anticipated, the storms will produce locally heavy downpours and frequent lightning.
