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.
