Significant flooding will continue to hamper much of the eastern United States over the next couple of days due to a stalling weather pattern, continuously pumping in rich, Atlantic moisture.
On Wednesday the Weather Prediction Center issued an uncommon “high risk” for excessive rainfall for western North Carolina and adjacent regions. Similar to the risk scale of the Storm Prediction Center, but with fewer categorical options, the scale assesses the risk potential for flash flooding. This is valid through Wednesday night.
Stalled upper-level low pressure over the Tennessee Valley combined with dominant high pressure over New England has resulted in heavy bands of rain and thunderstorms to move across the same areas of South & North Carolina, Virginia & West Virginia.
Two to four *more* inches of rain is forecast across interior Virginia and North Carolina with locally higher totals possible. This is in addition to previous heavy rainfall so far this week.
This, of course, comes on the heels of a serious rain event across the Great Lakes and Midwest in recent days, including significant flooding around Chicago.
Part of the issue is the long-term nature of this week’s rainfall. Drier weather and improved conditions aren’t expected until the weekend, setting up the potential for multiple days of heavy rainfall over already water-logged areas.
