MESOSCALE DISCUSSION 1711
   NWS STORM PREDICTION CENTER NORMAN OK
   0313 PM CDT TUE AUG 13 2013

   AREAS AFFECTED...SRN AND CNTRL GA...SRN SC...NRN FL

   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 

   VALID 132013Z - 132145Z

   PROBABILITY OF WATCH ISSUANCE...5 PERCENT

   SUMMARY...A MARGINAL WIND DAMAGE THREAT MAY DEVELOP ACROSS SRN AND
   CNTRL GA OVER THE NEXT FEW HOURS. THE THREAT SHOULD REMAIN TOO
   ISOLATED TO WARRANT WW ISSUANCE.

   DISCUSSION...THUNDERSTORMS ARE CURRENTLY INCREASING IN COVERAGE
   ACROSS SRN GA ALONG THE WRN EDGE OF A CORRIDOR OF MODERATE
   INSTABILITY. INSTABILITY IS MAXIMIZED ACROSS SERN GA WHERE
   MESOANALYSIS IS ESTIMATING MLCAPE IN THE 2000 TO 3000 J/KG RANGE. IN
   ADDITION...0-3 KM LAPSE RATES ACROSS SE GA ARE AROUND 8.0 C/KM. THIS
   COMBINED WITH SFC DEWPOINTS IN THE LOWER 70S F MAY BE ENOUGH FOR
   MARGINALLY SEVERE DAMAGING WIND GUSTS WITH THE STRONGER CELLS. THE
   THREAT MAY BE GREATEST NEAR THE GA COAST WHERE SFC TEMPS ARE IN THE
   MID 90S F.
