...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
A few thunderstorms remain possible through tonight from northern
Florida into southern Georgia, but severe weather is not expected.

...Discussion...
A cold front currently extends from southeast GA into northern FL,
and will continue to drift south though tonight. South of the
boundary, daytime head has led to around 1000 J/kg MUCAPE.

Strong southwest winds aloft will persist through the period, with
subtle height falls late as an upper trough moves across the lower
MS Valley. As the night progresses, SBCAPE is expected to weaken,
though elevated instability will remain near and south of the
sagging front. While lingering showers and a few thunderstorms
remain possible from northern FL into southwest GA, severe storms
are not expected due to limited instability and weak overall lift.
