   MESOSCALE DISCUSSION 0144
   NWS STORM PREDICTION CENTER NORMAN OK
   1143 AM CST FRI FEB 21 2014

   AREAS AFFECTED...SRN SC...SERN GA...NRN FL PENINSULA

   CONCERNING...SEVERE THUNDERSTORM WATCH 22...

   VALID 211743Z - 211845Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 22
   CONTINUES.

   SUMMARY...STRONG WINDS REMAIN POSSIBLE ALONG/AHEAD OF ADVANCING
   SQUALL LINE AS IT SURGES TOWARD COASTAL SC...AND ACROSS THE NRN FL
   PENINSULA.

   DISCUSSION...DISJOINTED SQUALL LINE IS ADVANCING STEADILY TOWARD
   COASTAL SC WITH NEW PRE-FRONTAL LINE SEGMENT MATURING OVER
   GEORGETOWN COUNTY SC.  THIS ACTIVITY WILL QUICKLY MOVE OFFSHORE OR
   EXPAND NWD INTO ERN PORTIONS OF NC.

   FARTHER SOUTH...LARGE SCALE SUPPORT WANES ACROSS THE NRN FL
   PENINSULA AND THIS APPEARS PARTLY RESPONSIBLE FOR BROADENING/SLOWING
   CORRIDOR OF CONVECTION THAT EXTENDS SWWD INTO THE NERN GULF BASIN. 
   WHILE THE MAIN BAND OF STRONG STORMS STRETCHES FROM SE OF JAX...SWWD
   TO SOUTH OF CTY...NUMEROUS WARM SECTOR SHOWERS HAVE RECENTLY
   DEVELOPED WELL AHEAD OF THIS LINE AS FAR SOUTH AS MLB.  DEEP LAYER
   FLOW WOULD SEEM SUPPORTIVE OF STORM ROTATION AND A FEW WEAK
   SUPERCELLS MAY ULTIMATELY EVOLVE ACROSS THIS REGION.  EVEN SO...IT
   APPEARS THE PRIMARY SEVERE THREAT SHOULD BE LOCALLY DAMAGING WINDS
   AND PERHAPS SOME LARGE HAIL.

   WILL CONTINUE TO MONITOR AREAS JUST SOUTH OF WW22 FOR POTENTIAL
   SEVERE THUNDERSTORM DEVELOPMENT.
