MESOSCALE DISCUSSION 0495
   NWS STORM PREDICTION CENTER NORMAN OK
   1209 PM CDT SAT MAR 29 2008
   
   AREAS AFFECTED...PARTS OF CNTRL GA INTO SOUTHERN SOUTH CAROLINA
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 291709Z - 291915Z
   
   STORM COVERAGE WILL CONTINUE TO INCREASE THROUGH 21-22Z.  SEVERE
   POTENTIAL APPEARS GENERALLY LOW...BUT TRENDS WILL BE MONITORED.
   
   SURFACE FRONT ASSOCIATED WITH A COLD INTRUSION TO THE LEE OF THE
   CENTRAL/SOUTHERN APPALACHIANS IS EXPECTED TO CONTINUE A GRADUAL
   SOUTHWESTWARD ADVANCEMENT THIS AFTERNOON.  AND...FORCING IN
   CONFLUENT LOW-LEVEL FLOW NEAR THIS BOUNDARY LIKELY WILL SUPPORT
   INCREASING THUNDERSTORM ACTIVITY...ROUGHLY ALONG AN AXIS FROM
   NEAR/SOUTH OF ATLANTA INTO AREAS SOUTH/WEST OF CHARLESTON SC. 
   DEEPENING CONVECTIVE DEVELOPMENT IS ALREADY UNDERWAY ACROSS THIS
   REGION...WHERE RELATIVELY STRONG HEATING IS CONTRIBUTING TO
   STEEPENING LOW-LEVEL LAPSE RATES.  BOUNDARY LAYER MOISTURE APPEARS A
   BIT MARGINAL FOR VIGOROUS UPDRAFTS...ESPECIALLY CONSIDERING THE
   RELATIVELY WEAKNESS OF MID-LEVEL LAPSE RATES.  AND...WEAK DEEP LAYER
   FLOW/SHEAR IS EXPECTED TO MINIMIZE THE SEVERE THREAT.  BUT...20-30
   KT EAST SOUTHEASTERLY STORM MOTIONS...AND THE POTENTIAL FOR
   SIGNIFICANT EVAPORATIVE COOLING ASSOCIATED WITH SIZABLE SUB-CLOUD
   BASE TEMPERATURE/DEW POINTS SPREADS...COULD CONTRIBUTE TO LOCALLY
   STRONG WIND GUSTS.
