VALID 241828Z - 242100Z
ISOLATED SEVERE ACTIVITY IS ANTICIPATED BY LATE AFTERNOON WITH A
THREAT OF DAMAGING WIND GUSTS.
SURFACE ANALYSIS SHOWS A WEAK LOW PRESSURE TROUGH FROM SERN LA INTO
THE FL PANHANDLE. CU FIELDS WERE INCREASING ACROSS THE AREA...WITH
ISOLATED STORMS SLOWLY DEVELOPING OVER SRN AL AND THE WRN FL
PANHANDLE. OTHER STORMS ARE EXPECTED TO FORM WWD ACROSS SRN MS AND
SERN LA LATER TODAY WHERE THE ATMOSPHERE CONTINUES TO DESTABILIZE.
MODERATE TO STRONG LEVELS OF DCAPE EXIST DUE TO DRY AIR ALOFT AS
WELL AS STEEP LOW LEVEL LAPSE RATES. THUS ANY STORMS THAT DEVELOP
WILL HAVE THE POTENTIAL FOR DAMAGING WIND GUSTS. WIND THREAT WILL
INCREASE IF STORMS CAN BOTH FORM/MERGE INTO SMALL CLUSTERS AND
FORWARD PROPAGATE SWWD WITH A 30KT DEEP LAYER MEAN WIND.
