   DAY 1 CONVECTIVE OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1117 AM CDT FRI MAR 27 2015

   VALID 271630Z - 281200Z

   ...THERE IS A MRGL RISK OF SVR TSTMS OVER PARTS OF FL AND COASTAL
   GA/SC...

   ...SUMMARY...
   ISOLATED STRONG/DAMAGING THUNDERSTORM WINDS ARE POSSIBLE TODAY
   ACROSS THE SOUTHERN AND EASTERN FLORIDA PENINSULA...AND COASTAL
   AREAS OF GEORGIA AND SOUTH CAROLINA.

   ...FL/GA/SC...
   WATER VAPOR LOOPS SHOW A LARGE UPPER TROUGH MOVING ACROSS THE
   EASTERN STATES. AT THE SURFACE...A LOW IS ANALYZED OVER SC...WITH A
   COLD FRONT STRETCHING SOUTHWESTWARD INTO SOUTHERN GA AND THE FL
   PANHANDLE. A RELATIVELY WARM/MOIST AND MARGINALLY UNSTABLE AIR MASS
   IS PRESENT AHEAD OF THE FRONT ACROSS MUCH OF FL AND COASTAL
   GA/SC...WITH SUFFICIENT BREAKS IN THE CLOUDS TO PROVIDE MODEST
   DIURNAL AFTERNOON HEATING. THUNDERSTORMS ARE EXPECTED TO INTENSIFY
   ALONG/AHEAD OF THE FRONT AND AFFECT THESE REGIONS THROUGH THE
   AFTERNOON. LOW LEVEL SHEAR IS RATHER WEAK...BUT DEEP LAYER EFFECTIVE
   SHEAR VALUES OF 40-50 KNOTS WILL BE SUFFICIENT FOR SOME CONVECTIVE
   ORGANIZATION. ISOLATED THUNDERSTORMS IN THIS REGION MAY ROTATE WITH
   A RISK OF LOCALLY DAMAGING GUSTS. AT THIS TIME...THE OVERALL THREAT
   OF SEVERE STORMS APPEARS MARGINAL.
