MESOSCALE DISCUSSION 0789
   NWS STORM PREDICTION CENTER NORMAN OK
   0505 PM CDT SAT MAY 14 2011
   
   AREAS AFFECTED...PORTIONS OF THE NRN FL PANHANDLE AND SERN GA
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 142205Z - 142300Z
   
   STORMS WITH ISOLATED WIND DAMAGE OR MARGINALLY SEVERE HAIL ARE
   POSSIBLE THE NEXT HOUR OR SO ACROSS PORTIONS OF THE NRN FL PANHANDLE
   AND SERN GA...THOUGH COVERAGE IS EXPECTED TO BE TOO LIMITED FOR A WW
   ISSUANCE.
   
   AT 2200Z...STRONG STORMS EXTENDED FROM NEAR VDI TO SOUTH OF VLD. 
   THESE STORMS ARE LOCATED JUST AHEAD OF AN EWD MOVING COLD FRONT. 
   VISIBLE SATELLITE IMAGERY SHOWS A RELATIVE MOIST PLUME OF MOISTURE
   FEEDING THIS CONVECTION FROM THE NERN GULF. THIS MOISTURE AND
   TEMPERATURES IN THE 80S WERE RESULTING IN MLCAPES UP TO 2000 J/KG.
   THIS INSTABILITY AND DEEP LAYER SHEAR AT 30 TO 40 KT IS SUPPORTIVE
   OF A FEW SEVERE MULTICELL STORMS. HOWEVER...THE AIR MASS EAST OF A
   30 SSE VDI TO EAST OF GNV LINE STILL REMAINS RELATIVELY COOL AND
   STABLE FROM EARLIER CONVECTION. THEREFORE AS STORMS MOVE INTO THIS
   MORE STABLE AIR MASS...STORMS ARE EXPECTED TO WEAKEN MOSTLY BELOW
   SEVERE CRITERIA.
