AREAS AFFECTED...CNTRL/SERN AL...SWRN GA AND WRN/CNTRL FL PNHDL

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 151452Z - 151645Z

ISOLD TORNADO/DAMAGING WIND THREATS APPEAR TO BE INCREASING ACROSS
PORTIONS OF CNTRL/SERN AL...SWRN GA AND WRN FL PNHDL.  AREA WILL BE
UPGRADED TO A CATEGORICAL SLIGHT RISK.

BANDS OF TSTMS CONTINUE TO FEED NWD AROUND ERN PERIPHERY OF AN UPPER
LOW LOCATED OVER ERN TX.  TSTMS ARE DEVELOPING IN AN AIR MASS THAT
IS VERY MOIST AND UNSTABLE WITH BOUNDARY LAYER DEW POINTS IN THE
MID-UPPER 70S. MESOANALYSIS DEPICTS STRONGEST SURFACE FLOW WAS
LOCATED ACROSS THE ERN GULF OF MEXICO INTO THE WRN FL PNHDL AND SERN
AL.  STREAMLINES DEPICT A BOUNDARY SITUATED NW-SE ACROSS CNTRL MS
INTO SRN AL.  VWPS VCNTY THIS BOUNDARY SUGGEST THAT 0-1KM SHEAR IS
INCREASING WITHIN THE LOW LCL ENVIRONMENT INDICATIVE OF AN ISOLD
TORNADO THREAT.  MAIN LIMITING FACTOR WILL BE MINIMAL INSOLATION. 
BUT...TSTMS THAT DEVELOP OVER THE GULF WILL MOVE NWD INTO THE ZONE
OF ENHANCED LOW LEVEL HELICITY AND MAY BEGIN TO EXHIBIT LOW LEVEL
ROTATION ACROSS CNTRL/SERN AL...SWRN GA AND THE WRN/CNTRL FL PNHDL.
