   MESOSCALE DISCUSSION 0461
   NWS STORM PREDICTION CENTER NORMAN OK
   0619 PM CDT SAT APR 25 2015

   AREAS AFFECTED...NRN FL...SRN/CNTRL GA

   CONCERNING...SEVERE THUNDERSTORM WATCH 114...115...

   VALID 252319Z - 260015Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   114...115...CONTINUES.

   SUMMARY...DMGG WIND GUST THREAT WILL CONTINUE WITH AN EWD MOVING
   QLCS ACROSS SRN/CNTRL GA AND NRN FL. PER COORDINATION WITH WFO
   JACKSONVILLE...WW 114 HAS BEEN EXPANDED SPATIALLY TO INCLUDE ALL OF
   SERN GA.

   DISCUSSION...QLCS WITH A LEWP STRUCTURE CONTINUES TO PROGRESS EWD
   ACROSS SRN GA AND THE FL PANHANDLE. CONVECTION ALONG THE SRN PORTION
   OF THE LINE IS NOT AS ROBUST/WELL-ORGANIZED...WITH THE GREATEST
   RELATIVE THREAT FOR DMGG WINDS LOCATED OVER SRN GA. INITIALLY
   DISCRETE SUPERCELLS N OF THE QLCS ARE UNDERGOING STORM INTERACTIONS
   WITH NEW CONVECTION DEVELOPING ALONG OUTFLOW...AND ARE CONGEALING
   WITH THE NRN PORTION OF THE LINE. HOWEVER...LARGE HAIL WILL REMAIN
   POSSIBLE WITH THESE STORMS FOR THE NEXT HOUR OR TWO. OTHERWISE...THE
   PRIMARY THREAT WILL REMAIN DMGG WIND GUSTS...AND THIS SHOULD EXTEND
   TO THE ATLANTIC COAST INTO THE EVENING AS RICH LOW-LEVEL MOISTURE
   MAINTAINS SUFFICIENT BUOYANCY TO SUSTAIN CONVECTION. EXTRAPOLATION
   OF CURRENT MOTION SUGGESTS THIS LINE WILL REACH THE COAST 02-03Z.
