...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PORTIONS OF
CENTRAL AND NORTHERN FLORIDA THIS AFTERNOON THROUGH TONIGHT....

...SUMMARY...
Isolated severe thunderstorms capable of producing strong to
damaging winds, a tornado, and some hail may impact parts of the
Florida Peninsula today into tonight.

...Central/Southeast FL this afternoon...
Only minor changes have been made to the ongoing forecast.  A
low-amplitude progressive shortwave trough is noted this morning
over the central Gulf of Mexico moving rapidly eastward toward FL. 
Ahead of this system, southerly low level winds are increasing over
FL, aiding in the slow northward progression of a weak surface warm
front.  Broken clouds and partial daytime heating is occurring south
of the front, which combined with dewpoints in the lower 70s, will
yield afternoon MLCAPE values of 1000-1500 J/kg.  Morning CAM
solutions suggest a few thunderstorms may develop during the
early-mid afternoon over the central peninsula and track toward the
east-central coast.  These storms would be near the retreating warm
front, and in a vertical shear profiles sufficient for updraft
rotation.  These storms could pose a threat of large hail and
gusty/damaging winds.

...Central/Northern FL after dark...
The main cluster of convection associated with the aforementioned
shortwave trough is expected to move into the FL Big Bend region
after dark.  Model solutions are in general agreement that these
storms will track east-northeastward along the retreating warm front
through the overnight period.  Relatively strong wind fields and
lift in this region suggest a risk of a supercell structures,
capable of damaging wind, hail, and perhaps a tornado or two.
