...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected on Thursday.

...Florida...

A shortwave upper trough within the area of broader eastern CONUS
troughing will be oriented from the Carolinas to the northeast Gulf
of Mexico Thursday morning. This system will shift east across FL
and offshore the Atlantic coast through 00z. At the surface, a cold
front located over north FL early in the day will develop southward
across the Peninsula. Low-level flow will be veered/northerly ahead
of the front, resulting in little low-level convergence.
Additionally, stronger large-scale ascent will remain well north of
the Peninsula. While weak destabilization is forecast (500-1000 J/kg
MLCAPE), mainly over the southern Peninsula, poor lapse rates and
warm midlevel temperatures will preclude severe thunderstorm
potential. Most CAMs and calibrated thunder guidance also indicate
little thunderstorm activity. Will maintain 10 percent general
thunder probabilities for the southeast FL coast, but even that may
be generous.
