   MESOSCALE DISCUSSION 0355
   NWS STORM PREDICTION CENTER NORMAN OK
   0945 PM CDT MON APR 14 2014

   AREAS AFFECTED...SRN AL...FL PANHANDLE...SWRN GA

   CONCERNING...SEVERE THUNDERSTORM WATCH 82...

   VALID 150245Z - 150345Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 82
   CONTINUES.

   SUMMARY...ISOLATED SEVERE THREAT CONTINUES ACROSS WW...ESPECIALLY
   OVER THE FL PANHANDLE.  WW EXTENSION MAY BE REQUIRED DOWNSTREAM TO
   ACCOUNT FOR EWD MOVING MCS.

   DISCUSSION...EXPANSIVE MCS CONTINUES ITS EWD PROGRESSION ALONG THE
   CNTRL GULF COAST WITH FORWARD PROPAGATION OF FRONTAL CONVECTION AT
   ROUGHLY 35-40KT.  AN MCV APPEARS TO BE EVOLVING ALONG THE AL/FL
   BORDER OVER ESCAMBIA COUNTY AL WITHIN THE BROADER PRECIP
   SHIELD...JUST AHEAD OF WEAK SFC LOW.  IN RESPONSE A FAIRLY
   WELL-DEFINED WARM-ADVECTION WING WITH ROBUST EMBEDDED UPDRAFTS HAS
   FORMED OVER THE CNTRL FL PANHANDLE.  THIS CONVECTIVE COMPLEX SHOULD
   CONTINUE EWD ACROSS THE REMAINDER OF FL PANHANDLE INTO SWRN GA OVER
   THE NEXT SEVERAL HOURS.  TRUE MARITIME TROPICAL AIR MASS HAS
   STRUGGLED TO MOVE INLAND BUT IMMEDIATE COASTAL AREAS HAVE RECOVERED
   WITH SFC DEW POINTS NEAR 70.  WHILE ISOLATED SUPERCELLS REMAIN
   POSSIBLE IT APPEARS THE GREATEST SEVERE RISK IS DAMAGING WINDS WITH
   FORWARD PROPAGATING SQUALL LINE.
