MESOSCALE DISCUSSION 2528
   NWS STORM PREDICTION CENTER NORMAN OK
   1107 PM CST THU DEC 09 2004
   
   AREAS AFFECTED...W-CNTRL GA INTO CNTRL SC
   
   CONCERNING...TORNADO WATCH 918...
   
   VALID 100507Z - 100630Z
   
   THROUGH 06Z...GREATEST POTENTIAL FOR ISOLATED TORNADOES APPEARS TO
   BE FROM AROUND MCN NEWD INTO UPSTATE SC /N OF AGS/.
   
   AS OF 0450Z...REGIONAL RADAR IMAGERY SHOWS MAJORITY OF INITIAL
   CONVECTIVE ACTIVITY ALONG/N OF WARM FRONT FROM NERN GA INTO NWRN SC
   AND INTO CNTRL NC. HOWEVER...ADDITIONAL CLUSTERS OF STORMS HAVE
   INCREASED IN COVERAGE AND INTENSITY FROM NE OF MCN SWWD INTO SWRN
   GA. LATEST MESOANALYSIS AND RUC DIAGNOSTIC FIELDS INDICATE THAT
   THESE STORMS ARE FORMING WITHIN LOW-LEVEL MOISTURE AXIS /I.E.
   DEWPOINTS IN THE UPPER 60S TO LOWER 70S/ WHERE MLCAPES REMAIN AROUND
    1000 J/KG. CURRENT VWP FROM CNTRL GA CONTINUES TO INDICATE VERY
   FAVORABLE SHEAR PROFILES FOR SUPERCELLS AND ISOLATED TORNADOES WITH
   0-6 KM SHEAR OF 50-60 KTS AND 0-1 KM SRH OF 200-250 M2/S2. 
   
   GIVEN THIS COMBINATION OF MODERATE INSTABILITY AND STRONG SHEAR...IT
   APPEARS THAT THE GREATEST POTENTIAL FOR ISOLATED TORNADOES THROUGH
   06Z WILL BE IN A CORRIDOR FROM MCN NEWD TO NW OR N OF AGS.
   ELSEWHERE...POTENTIAL FOR AN ISOLATED TORNADO WILL EXIST WITH STORMS
   INTERACTING WITH WARM FRONT OVER NWRN SC. HOWEVER...ORIENTATION OF
   WARM FRONT TO OBSERVED STORM MOTIONS SUGGEST THAT RESIDENCE TIME
   WITHIN FAVORABLE REGION OF FRONTAL ZONE WILL REMAIN SHORT.
