   AREAS AFFECTED...SERN MS...SRN AL...WRN FL PANHANDLE
   
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL 
   
   VALID 271630Z - 271830Z
   
   ...STRONG WINDS MAY ACCOMPANY SQUALL LINE AS IT MOVES EWD INTO SRN
   AL/WRN FL PANHANDLE...
   
   TRAILING PORTIONS OF WEAK UPPER SHORTWAVE TROUGH MAY BE INFLUENCING
   RECENT INCREASE IN EXPANDING CLUSTER OF THUNDERSTORMS OVER SRN MS. 
   THIS ACTIVITY MAY CONTINUE TO EVOLVE AND SURGE EWD ACROSS SRN
   PORTIONS OF AL AND WRN PORTIONS OF THE FL PANHANDLE...ESPECIALLY
   GIVEN THE INCREASINGLY WLY COMPONENT THROUGH A DEEP LAYER.  STRONG
   BOUNDARY LAYER HEATING AND HIGH INSTABILITY SUGGEST LEADING EDGE OF
   COMPLEX MAY PRODUCE STRONG WIND GUSTS. WW MAY BE REQUIRED
   DOWNSTREAM IF THIS UPWARD TREND CONTINUES.
