   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.
