THE SEVERE WEATHER THREAT FOR TORNADO WATCH 47 CONTINUES.
DMGG WIND THREAT MAY BE LOCALLY MAXIMIZED ACROSS S-CNTRL GA DURING
THE NEXT FEW HOURS AS BOWING SEGMENT OF LARGER SCALE QLCS CONTINUES
EWD AROUND 35 KTS.
RECENT SURFACE ANALYSIS PLACES A MARINE WARM FRONT LIFTING NWD INTO
SWRN GA AHEAD OF AN APPROACHING SW-NE ORIENTED QLCS. S OF THIS
BOUNDARY...A MOIST/DESTABILIZING LOW LEVEL AIRMASS IS CHARACTERIZED
BY TEMPS WARMING INTO THE MID 70S WITH DEWPOINTS RISING INTO THE
LOWER 60S. REGIONAL RADAR MOSAIC SHOWS A MORE N-S ORIENTATION OF
QLCS ACROSS SWRN GA...THAT IS COINCIDENT WITH A WELL DEVELOPED REAR
INFLOW JET SIGNATURE--EVIDENT VIA TIME HEIGHT DISPLAY VIA KEOX THE
PAST FEW HOURS /50+ KTS AT 2 KM/. IN ADDITION TO THE LOCALIZED
MAXIMUM DMGG WIND POTENTIAL E OF THE QLCS ACROSS S-CNTRL GA...ISOLD
BRIEF TORNADO POTENTIAL SEEMS TO EXIST...ESPECIALLY WITH ANY
LONG-LIVED MESOVORTEX THAT MAY DEVELOP. FARTHER SW ACROSS THE FL
PANHANDLE...DOWNWARD MOMENTUM TRANSFER MAY BE LESSENED TO A CERTAIN
EXTENT AS TSTM MEAN MOTION GENERALLY MOVES ATOP EXISTING COLD POOL
IN A TRAINING-LIKE FASHION.
