   NWS STORM PREDICTION CENTER NORMAN OK
   1140 PM CST FRI MAR 02 2012
   
   AREAS AFFECTED...NRN GA THROUGH WRN SC AND SWRN NC
   
   CONCERNING...TORNADO WATCH 65...
   
   VALID 030540Z - 030715Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 65 CONTINUES.
   
   THE THREAT FOR PRIMARILY DAMAGING WIND AND ISOLATED TORNADOES WILL
   PERSIST THROUGH THE EARLY MORNING FROM NRN GA INTO WRN SC. A MORE
   LIMITED THREAT EXISTS IN WRN NC. SEVERE THREAT MAY BEGIN TO INCREASE
   EAST OF WW 65 INTO SCNTRL THROUGH ECNTRL NC AFTER 07Z.
   
   WEDGE FRONT PERSISTS FROM E-CNTRL NC SWWD TO NEAR THE NC-SC BORDER
   BEFORE CURVING BACK NORTHWARD INTO THE SRN APPALACHIANS. THE SEVERE
   THREAT WILL PERSIST ALONG AND SOUTH OF THIS BOUNDARY WHERE A 60 KT
   SLY LLJ HAS TRANSPORTED 60F DEWPOINTS INTO WARM SECTOR. MLCAPE HAS
   DECREASED TO LESS THAN 500 J/KG DUE TO A GRADUAL STABILIZATION OF
   THE BOUNDARY LAYER...BUT INFLOW PARCELS REMAIN CLOSE ENOUGH TO THE
   SURFACE FOR A DAMAGING WIND AND TORNADO THREAT. HODOGRAPHS ARE VERY
   LARGE OVER NRN GA AND INTO UPSTATE SC WHERE THE STRENGTHENING LLJ
   INTERSECTS THE BOUNDARY. THIS ENVIRONMENT WILL CONTINUE TO POSE A
   THREAT FOR DAMAGING WIND AND ISOLATED TORNADOES AS STORMS DEVELOP
   EWD. SEVERE THREAT OVER WRN NC APPEARS LIMITED WHERE THE BOUNDARY
   LAYER IS STABLE NORTH OF THE WEDGE FRONT. THIS FEATURE WILL PROBABLY
   NOT MOVE MUCH DURING THE NEXT COUPLE HOURS.
   
   THE SEVERE THREAT MAY BEGIN TO SPREAD EAST OF WW 65...ESPECIALLY
   AFTER 07Z AND WFO GREENVILLE-SPARTANBURG CAN LOCALLY EXTEND AS
   NECESSARY. HOWEVER ANOTHER WW MAY EVENTUALLY BE NEEDED LATER THIS
   MORNING FARTHER EAST INTO SCNTRL NC AND CNTRL SC.
