   AREAS AFFECTED...SERN AL/FAR SWRN GA/NRN FL PANHANDLE
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 231932Z - 232030Z
   
   OCCURRENCE OF ROTATION IN ISOLD STORMS HAS INCREASED SOMEWHAT OVER
   THE PAST HOUR...AND THIS TREND WILL CONTINUE OVER THE NEXT FEW HOURS
   IN A NARROW CORRIDOR...PRIMARILY NEAR THE SERN AL/SWRN GA/NRN FL
   PANHANDLE BORDERS. DUE TO ISOLD AND BRIEF NATURE OF ROTATION...A WW
   IS NOT ANTICIPATED.
   
   GULF SURFACE LOW IS CURRENTLY ANALYZED IN FAR SRN MS...WITH ELY
   SURFACE WINDS PREDOMINANT TO THE E OF THE LOW ACROSS PORTIONS OF
   AL/GA/FL. WINDS VEER SHARPLY FROM ELY TO SLY FROM 0 TO 3000
   FT...ROUGHLY IN THE LOWEST 1 KM...AS REFLECTED ON RECENT VAD WIND
   PROFILE DATA IN E CNTRL AL. ENHANCED SRH IN THE LOWEST 1 KM WILL
   CONTINUE TO ALLOW BRIEF ROTATION AND PERHAPS AN ISOLD TORNADO IN A
   VERY MOIST/BUOYANT ENVIRONMENT. ALTHOUGH INSTABILITY IS
   WEAK...RECENT RADAR TRENDS SHOW DISCRETE CELLS AND SMALL CLUSTERS OF
   STORMS DEVELOPING ON THE ERN PERIPHERY OF EARLIER HEAVY RAINFALL.
   STORMS THAT DEVELOP IN THESE AREAS MAY BE ABLE TO PERSIST LONGER
   THAN AREAS TO THE NORTHWEST DUE TO GREATER INSTABILITY. THIS HAS
   BEEN SUPPORTED BY LIGHTNING TRENDS...AS AREAS TO THE NORTH AND WEST
   OF THE DISCRETE CELLS/SMALL CLUSTERS HAVE BEEN UNABLE TO PRODUCE
   LIGHTNING GIVEN WEAK UPDRAFTS. REGARDLESS...ANY ROTATION WILL LIKELY
   BE BRIEF...AND A WW IS NOT ANTICIPATED.
