A warm front, drifting northward from the Carolinas across the lower Mid-Atlantic, triggered scattered thunderstorms with heavy rain.  Strong heating during the afternoon supported surface-based CAPE values rising into the 2,000 to 2,500 J/Kg range, while precipitable water values ranged from around 1.5 inches along the Blue Ridge to in excess of 1.8 inches across the central Piedmont of Virginia and North Carolina.  Wind speeds through 700 mb were generally around 10 knots, supporting slow cell movement that would contribute to prolonged heavy rainfall over some locations. Many of the storms produced rainfall at 3 to 5 inch per hour rates, which resulted in flash flooding of small streams in the local area.
