   AREAS AFFECTED...SRN SC...SRN GA...NRN FL...SERN AL
   
   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 
   
   VALID 111815Z - 112015Z
   
   STORMS WILL CONTINUE TO DEVELOP WITH A FEW PRODUCING DAMAGING WINDS.
   A WW IS NOT ANTICIPATED AT THIS TIME.
   
   A VERY UNSTABLE AIR MASS HAS DEVELOPED ALONG AND E OF A WEAK SURFACE
   TROUGH AXIS...FROM CNTRL SC INTO S CNTRL GA...NRN FL AND SERN AL.
   WIND FIELDS ALOFT ARE QUITE WEAK...THUS STORM MODE WILL BE MAINLY
   PULSE WITH REGENERATION ALONG OUTFLOW. STRONG HEATING WILL CONTINUE
   TO STEEPEN LOW LEVEL LAPSE RATES AND WILL FAVOR STRONG OUTFLOW
   WINDS. STORM MOTIONS WILL INITIALLY BE VERY SLOW AND WILL RESULT IN
   EXTREMELY HEAVY RAIN RATES. INITIALLY...STORM MOTIONS WILL BE SLOW
   WITH LOCALIZED WIND THREAT. HOWEVER...4KM WRF MODELS SUGGEST THAT
   STORM/OUTFLOW MERGERS MAY EVENTUALLY RESULT IN A FORWARD PROPAGATING
   SYSTEM WHICH WOULD MOVE INTO SERN GA/NRN FL LATER THIS AFTERNOON. A
   WW COULD BE REQUIRED IF AN ORGANIZED MCS DEVELOPS LATER TODAY.
