   CONCERNING...SEVERE THUNDERSTORM WATCH 68...
   
   VALID 271949Z - 272045Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 68
   CONTINUES.
   
   MIX OF DISCRETE SUPERCELLS AND SEMI-ORGANIZED BANDS OF STORMS WILL
   CONTINUE TO POSE VERY LARGE HAIL...DAMAGING WIND AND ISOLATED
   TORNADO THREATS.  STRONGEST RISKS WILL SHIFT ACROSS SRN GA AND THE
   CNTRL FL PANHANDLE THROUGH EARLY EVENING.  CURRENT SEVERE
   THUNDERSTORM WATCH 68 EXPIRES AT 21Z...BUT WILL EITHER BE LOCALLY
   EXTENDED OR REPLACED WITH ANOTHER WATCH BY THEN.  
   
   WEAK MID-LEVEL WAVE CONTINUES TO SKIRT ACROSS ERN AL/NRN GA AT
   MID-AFTERNOON WITH GENERALLY UNIDIRECTIONAL WSW DEEP-LAYER FLOW
   ALONG IT/S SRN FLANK.  MAINTENANCE OF 7+ DEG C PER KM H5-H7 LAPSE
   RATES AND SUBSTANTIAL CAPE IN THAT LAYER WERE CONTRIBUTING TO ROBUST
   UPDRAFTS AND VERY LARGE HAIL IN DISCRETE SUPERCELLS. EXPECT ZONE OF
   STRONGER STORMS TO SHIFT SLOWLY ESE THROUGH SRN GA AND INTO THE FL
   PANHANDLE THROUGH THE EARLY EVENING.  PRESENCE OF 50 KTS OF
   DEEP-LAYER SHEAR WILL CONTINUE TO BE FAVORABLE FOR SUPERCELLS. 
   WHILE THE TORNADO THREAT IS NOT PARTICULARLY HIGH...STORM BOUNDARY
   INTERACTIONS MAY AUGMENT LOW-LEVEL HELICITY FOR A BRIEF SPIN-UP.
