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.
