Latest Forecast
A storm system tracking from the Great Lakes region into southeastern Canada will bring showers or intermittent, light rain to northern MD and southeastern PA between 1-8 PM. The mid-Atlantic States will be deep within the system's warm sector, so high temperatures should be 10-15 degrees above average this afternoon despite extensive cloud cover. A cold front trailing southward from the system will sweep through the Commonwealth tonight and usher cooler air into the region by Saturday morning. After a lull in the wet weather Friday night, a second storm system will track northeastward along the spine of the Appalachians on Saturday and bring steadier, soaking rain to the Lower Susquehanna Valley. Rain should overspread the region from south-to-north between ~7-11 AM, fall heavily at times during the afternoon hours and then taper off Saturday evening. A general 0.50-1.00" of rain is expected from this afternoon through Saturday night with locally higher amounts along the I-95 corridor. Due to the ongoing drought, the rain will be largely beneficial. Behind the system, skies will partially clear late Saturday night into Sunday morning, and westerly winds of 12-25 mph with gusts up to 45 mph will then buffet the region Sunday afternoon and evening. In addition, temperatures over the weekend will be much closer to average with highs in the low-to-mid 40s both Saturday and Sunday.
