...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
AN UPPER LEVEL TROUGH WILL DE-AMPLIFY AS IT MOVES FROM THE SRN
PLAINS INTO THE MID/LOWER MS VALLEY REGION ON SAT. WEAK LOW PRESSURE
WILL DEVELOP AT THE SURFACE OVER THE N-CENTRAL GULF OF MEXICO AND
MOVE ACROSS THE FL PANHANDLE/SRN GA LATE IN THE PERIOD. A WARM
FRONTAL BOUNDARY WILL LIFT NWD ACROSS NRN FL AND INTO THE COASTAL
CAROLINAS AS A COLD FRONT TRAILING SWD FROM THE SFC LOW MOVES EWD
INTO THE FL PANHANDLE. ELSEWHERE ACROSS THE CONUS...A GENERALLY
DRY/STABLE AIR MASS WILL REMAIN IN PLACE.

...NRN FL/SRN GA...
INCREASING SE-SLY LOW-LEVEL FLOW WILL RESULT IN MID-UPPER 60S SFC
DEW POINTS SPREADING AS FAR N AS NRN FL/SRN GA SAT. A CORRIDOR OF
MODEST DESTABILIZATION /MLCAPES OF 500 TO LOCALLY 1000 J/KG/ WILL
LIKELY DEVELOP IN THIS AREA. CONCURRENT STRENGTHENING OF LOW-MID
LEVEL WIND FIELDS WILL YIELD AN ENVIRONMENT THAT MAY SUPPORT AN
ISOLATED SVR WIND THREAT WITH TSTMS WITHIN THE WARM SECTOR. THE
PRIMARY LIMITING FACTOR PRECLUDING HIGHER SVR PROBS IS THE EXPECTED
DEGREE OF DESTABILIZATION.
