...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE SOUTHEAST AND EASTERN CAROLINAS...

...SUMMARY...
Thunderstorms associated with marginally severe wind gusts will be
possible on Saturday from parts of the eastern Gulf Coast to the
southern Atlantic Seaboard.

...Eastern Gulf Coast/Southern Atlantic Seaboard...
An upper-level low is forecast to move northeastward across the
Ozarks on Saturday as southwest mid-level flow remains from the
Southeast into the Carolinas. At the surface, a cold front is
forecast to become quasi-stationary on Saturday from the Florida
Panhandle northeastward into far eastern North Carolina. Ahead of
the front, surface dewpoints in the lower to mid 60s F will allow
for weak destabilization by afternoon. Thunderstorm development will
be possible along the axis of instability as low-level convergence
increases during the day. The presence of strong deep-layer shear
may be enough for an isolated wind damage threat, with the threat
maximizing across the northwestern edge of the moist sector from the
Florida Panhandle to eastern South Carolina.  The threat may also
affect far eastern North Carolina during the evening as a low-level
jet translates northeastward.
