AREAS AFFECTED...SERN AL/WRN FL PANHANDLE/SWRN
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 261912Z - 262015Z
..THERE IS SOME POTENTIAL THIS AFTN FOR ISOLD SVR TSTMS THIS AFTN.
THE MAIN THREATS ARE STRONG/SVR WIND GUSTS OR BRIEF TORNADOES...
DEEPLY SHEARED ENVIRONMENT CONTINUES TO BE FAVORABLE FOR
STRONG/ROTATING UPDRAFTS AS NOTED ON AREA RADARS. OF PARTICULAR
INTEREST WAS A STORM JUST NORTHEAST OF TOI EXITING NRN BULLOCK CO
ALABAMA. THIS CELL HAD EXHIBITED A PERSISTENT LOW LEVEL
ROTATION...AND EARLIER HAD A REPORT OF FUNNEL CLOUD. ANOTHER
POTENTIAL CELL IS JUST WEST OF TOI...AT THE NRN BREAK IN THE
CONVECTIVE LINE SEGMENT. AREA VAD WIND DATA FROM MONTGOMERY AL AND
ATLANTA IS SUPPORTIVE OF ROTATING CELLS...AND THE MAIN ISSUE THUS
FAR HAS BEEN THE INSTABILITY. SFC DEWPOINTS DROP OFF INTO 40S/50S IN
CNTRL/SRN GA...AND APPEARS THE GREATEST THREAT WILL REMAIN ACROSS
SERN AL AND THE WRN FL PANHANDLE...WHERE DEWPOINTS ARE IN THE
MID/UPPER 60S.
WATCH MAY BE POSSIBLE FOR AREAS WHICH HAVE HEATED UP AHEAD OF THIS
CONVECTIVE LINE NOW EXTENDING INTO THE WRN FL PANHANDLE.
