...THERE IS A MARGINAL RISK FOR EXCESSIVE RAINFALL FOR PORTIONS OF
THE CAROLINAS, VIRGINIA AND WEST VIRGINIA...
...Mid-Atlantic...
The low and surface front will be increasingly more progressive
through this period as it lifts north and east through the
Mid-Atlantic region to the Great Lakes. Showers and thunderstorms
will continue to accompany the surface front, producing another 1
to 2 inches. The Marginal Risk area that was already effect was
adjusted to reflect the latest trend in WPC QPF, which entailed
trimming the south and east bounds of the area. Very localized
areas of runoff and flash flooding will be possible during this
period.
