0927 AM CDT MON SEP 27 2004

AREAS AFFECTED...ERN GA/SC

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 271427Z - 271630Z

AN ISOLATED TORNADO THREAT WILL LIKELY INCREASE AS MINI-SUPERCELLS
TRACK NWWD ACROSS ERN GA AND PARTS OF SC. A TORNADO WATCH WILL BE
ISSUED SOON.

THE CENTER OF TROPICAL DEPRESSION JEANNE IS CURRENTLY LOCATED ACROSS
SRN GA. NARROW RAINBANDS EXTEND SEWD AROUND THE NRN PART OF JEANNES
CIRCULATION. SEVERAL MINI-SUPERCELLS ARE ONGOING IN THE OUTER
RAINBANDS ACROSS NRN AND ERN SC WHERE FORECAST SOUNDINGS SHOW STRONG
VEERING WIND PROFILES AT THE LOW TO MID-LEVELS. THE SHEAR BECOMES
EVEN STRONGER FARTHER SOUTHWEST ACROSS ERN GA AND THIS WILL FAVOR AN
ISOLATED TORNADO THREAT WITH ROTATING CELLS THAT TRACK NWWD ACROSS
THE REGION. IN ADDITION...SFC ANALYSIS SHOWS A MOIST TONGUE ACROSS
SRN SC AND ERN GA WHERE DEWPOINTS ARE IN THE MID TO UPPER 70S F.
THIS MOIST TONGUE WILL MOVE NWD INTO NC ALLOWING LCL HEIGHTS TO
DROP. THIS COMBINED WITH DESTABILIZATION OF THE BOUNDARY LAYER AND
THE STRONG WIND PROFILES ALREADY IN PLACE WILL INCREASE THE TORNADO
THREAT BY EARLY AFTERNOON.
