...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms will be possible across parts of the Gulf
Coast and Southeast, but severe thunderstorm potential is expected
to be low.

...Southeast GA into north FL...

A surface cold front will be located near the South Carolina coast
southwest to western FL Panhandle and northern Gulf of Mexico at
12z. A moist airmass will exist ahead of the front across northern
FL and southeast GA. Modest destabilization, with MLCAPE to 1000
J/kg is forecast. Forecast soundings indicate capping will limit
thunderstorm activity except very near the southeastward-advancing
cold front. Isolated thunderstorms will be possible by early
afternoon. A couple of strong storms with gusty winds are possible,
and possibly hail. However, overall severe potential appears
limited.
