…Locally Heavy Rainfall Expected Through Friday…

.The combination of a weak stalled frontal boundary across West
Virginia and Virginia, and an area of low pressure laden with
tropical Gulf Moisture moving northward from the southern
Appalachians, will bring periods of heavy rain showers and a few
thunderstorms with torrential downpours to the central Mid-
Atlantic States. The Highlands of Virginia and West Virginia, and
into the High Country of North Carolina will be most susceptible
to rapid runoff of this rainfall due to the steep terrain.
Expected rainfall of 2 to 4 inches is possible through Friday,
some of this rain occurring in a very short period of time. If
this occurs, streams will rise rapidly and may quickly lead to
flash flooding.
