...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
CENTRAL AND NORTHERN FLORIDA...

...SUMMARY...
Isolated severe thunderstorms will be possible across the
western/north-central Florida Peninsula through the afternoon and
evening, and possibly across southeastern Georgia and the coastal
Carolinas tonight. Locally damaging winds should be the main threat.

...Florida...
Only a minor adjustment was made to northern portions of the risk
area to account for stabilization from extensive precipitation and
current squall line position. For more information see mesoscale
discussion 1710.

.PREV DISCUSSION... /ISSUED 1013 AM CST Fri Dec 14 2018/

...FL...
No changes have been made to the ongoing forecast.  Morning radar
loop shows widespread showers and thunderstorms affecting the west
coast of the FL Peninsula, with activity spreading eastward across
the SLGT risk region.  This will significantly limit
heating/destabilization.  Nevertheless, forecast soundings show weak
but sufficient CAPE values and strong deep-layer shear today into
tonight.  This may result in a few organized cells within the
broader precipitation shield.  Rotating/bowing segments capable of
damaging winds, or perhaps a tornado spinup are the main concerns
today.  The threat should end from west to east across the FL
Peninsula this afternoon and evening.

..Carolina Coast...
Strong surface pressure-falls are forecast over the eastern
Carolinas later today.  This will result in strengthening southerly
low level winds and rapid destabilization along the immediate coast.
Model solutions suggest multiple clusters of thunderstorms offshore
this evening and tonight.  If a few of these stronger storms can
spread inland, a marginal risk of damaging winds would be present.
