VALID 102000Z - 111200Z

THERE IS A SLGT RISK OF SVR TSTMS TO THE RIGHT OF A LINE FROM 30 ENE
CHS 30 SE FAY GSB 45 WSW ECG 25 NE ECG.

GEN TSTMS ARE FCST TO THE RIGHT OF A LINE FROM 35 ENE AQQ 35 N ABY
20 ESE TYS 50 NW HTS 25 NW ZZV 15 ESE YNG DUJ 35 N CXY ACY.

GEN TSTMS ARE FCST TO THE RIGHT OF A LINE FROM 20 N OTH 15 WSW MFR
55 NNE SAC 25 NE SCK 35 W MER 10 S MRY.

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PORTIONS OF ERN NC AND
FAR ERN SC...

...ERN NC/FAR ERN SC...
A COLD FRONT IS CURRENTLY LOCATED ACROSS FAR WRN SC AND ERN GA. A
LINE OF CONVECTION IS CURRENTLY ONGOING ALONG AND JUST AHEAD OF THE
BOUNDARY. FARTHER EAST...OBJECTIVE ANALYSIS SHOWS A DESTABILIZING
AIR MASS OFF THE COAST OF SC WITH LI VALUES AT -6. ALTHOUGH A LARGE
AREA OF RAIN IS ABOUT TO MOVE INTO THE SLIGHT RISK AREA...THE
UNSTABLE MARINE AIR WILL LIKELY ADVECT NWD BEHIND IT. THIS WOULD
ALLOW THE AIRMASS TO RECOVER QUICKLY. IN ADDITION...DEEP LAYER SHEAR
IS EXPECTED TO INCREASE FROM 35 TO 40 KT INTO THE 50 TO 55 KT RANGE
ACROSS THE INSTABILITY AXIS AHEAD OF A SHARP UPPER-TROUGH MOVING
INTO THE APPALACHIAN MTNS. AS A RESULT...AN ISOLATED WIND DAMAGE
POTENTIAL WILL BE LIKELY WITH NEW CELLS THAT DEVELOP AHEAD OF THE
LINE OR WITH STRONG CELLS IN THE LINE THAT MOVE INTO THE INSTABILITY
AXIS. IN ADDITION...THE BACKED LOW-LEVEL ACROSS THE SLIGHT RISK AREA
WOULD MAKE A TORNADO POSSIBLE WITH ISOLATED STRONGER CELLS AHEAD OF
THE LINE LATER THIS AFTERNOON.

...NERN FL/SERN GA...
A LINE OF CONVECTION MOVING ACROSS NRN FL AND SERN GA WILL CONTINUE
TO MOVE EWD INTO THE ATLANTIC COASTAL AREAS OVER THE NEXT FEW HOURS.
SOME SFC HEATING HAS OCCURRED IN THE JAX VICINITY WITH SFC TEMPS IN
THE MID 70S F. THIS IS RESULTING IN WEAK INSTABILITY. THIS COMBINED
WITH 55 TO 60 KT OF 0-6 KM SHEAR WILL MAINTAIN A THREAT FOR A
DAMAGING WIND GUST OR TWO BEFORE THE LINE MOVES OFFSHORE.
