   AREAS AFFECTED...ECNTRL/NERN MS...CNTRL/NRN AL...WCNTRL GA
   
   CONCERNING...SEVERE POTENTIAL...TORNADO WATCH LIKELY 
   
   VALID 261625Z - 261800Z
   
   BAND OF CUMULUS OVER CNTRL MS APPEARS TO BE DEEPENING WITHIN A ZONE
   OF WEAKLY CONFLUENT LOW-LEVEL FLOW AND WHERE THE BOUNDARY LAYER WAS
   HEATING INTO THE MID-UPPER 70S.  THIS MAY BE THE START OF AN ACTIVE
   AFTERNOON/EVENING AS THE STORMS GRADUALLY EVOLVE ENE INTO CNTRL/NRN
   AL AND WCNTRL GA.
   
   THE DEEP LAYER FLOW IS GENERALLY UNIDIRECTIONAL WSWLY...THOUGH SPEED
   SHEAR IS MORE THAN SUFFICIENT FOR SUPERCELLS.  MID-LEVEL LAPSE RATES
   IN EXCESS OF 7 DEG C PER KM AND MAGNITUDE OF VERTICAL SHEAR WILL
   YIELD VERY LARGE HAIL WITH ANY STORM.  AS STORMS APPROACH THE BACKED
   LOW-LEVEL FLOW IN VICINITY OF THE WARM/WEDGE FRONT ACROSS CNTRL/NRN
   AL AND WCNTRL GA...CONCERN IS FOR DISCRETE SUPERCELLS TO PRODUCE A
   FEW TORNADOES.  
   
   ALTHOUGH FIRST SIGNS OF INITIATION ARE LIMITED TO MS...EXPECT THAT
   ADDITIONAL DISCRETE STORMS WILL FORM IN THE WARM SECTOR ACROSS
   CNTRL/SRN AL AND WCNTRL GA THROUGH THE AFTERNOON.
