Valid 090100Z - 091200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Organized severe thunderstorms are not forecast tonight across the
contiguous United States.
...Synopsis...
The remnants of Tropical Cyclone Nate will continue to shear
north-northeast from TN-KY into the upper OH Valley tonight. A very
moist boundary layer will extend from the Carolina coast into the
Mid-Atlantic states. Weak buoyancy/ascent will promote isolated
thunderstorms across the NC/VA region during the evening. Weak
tropospheric lapse rates will limit updraft vigor and the risk for a
severe thunderstorm. A low probability (10%) for widely-spaced
thunderstorms will seemingly exist from the northeast Gulf Coast to
southern New England during the overnight.
