AREAS AFFECTED...ERN MS...WRN AL

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 231832Z - 231930Z

THUNDERSTORMS ACROSS ERN MS AND WRN AL MAY HAVE A POTENTIAL FOR
STRONG GUSTY WINDS LATE THIS AFTERNOON. THE WIND DAMAGE POTENTIAL
WILL REMAIN VERY MARGINAL AND A WW IS NOT ANTICIPATED ACROSS THE
REGION.

THE LATEST SFC ANALYSIS SHOWS AN INVERTED SFC TROUGH LOCATED ACROSS
SRN AND CNTRL MS WITH A MOIST AXIS LOCATED JUST EAST OF THE TROUGH
WHERE DEWPOINTS ARE IN THE LOWER 70S F. TEMPERATURES WILL CONTINUE
TO INCREASE WITH MODERATE TO STRONG INSTABILITY REMAINING IN PLACE
ALONG THE MOIST AXIS FROM COLUMBUS MS SWD TO NEAR MOBILE AL.
ALTHOUGH WSR-88D VWPS SHOW VERTICAL SHEAR PROFILES GENERALLY BELOW
20 KT...THE INSTABILITY SHOULD BE SUFFICIENT FOR STRONG PULSE
THUNDERSTORMS. AS LOW-LEVEL LAPSE RATES STEEPEN OVER THE NEXT FEW
HOURS...STRONG GUSTY WINDS AND VERY HEAVY RAIN WILL BE POSSIBLE WITH
THE MORE INTENSE PULSE STORMS. THE GREATEST POTENTIAL FOR GUSTY
WINDS WILL LIKELY BE BETWEEN 20Z AND 22Z ACROSS THE REGION.
