   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 246 CONTINUES.
   
   TORNADO THREAT CONTINUES ACROSS MUCH OF SC/NC...WITH ADDITIONAL
   THREATS OF HAIL/DMGG WINDS.
   
   SMALL SUPERCELLS CONTINUE TO DEVELOP S OF A QUASI-STATIONARY
   FRONT...NOW ORIENTED ROUGHLY NEAR VIRGINIA BEACH AND EXTENDING WSWWD
   THROUGH GREENVILLE-SPARTANBURG. DESPITE DIURNAL COOLING...THE AREA
   REMAINS MODERATELY UNSTABLE...WHILE 40 TO 50 KT 0-6 KM BULK SHEAR
   AND FAVORABLE CURVATURE IN LOW LEVEL WIND PROFILES CONTINUE TO
   SUPPORT SUPERCELL DEVELOPMENT. SEVERAL CELLS HAVE QUICKLY BECOME
   TORNADIC NEAR THE FRONT...ALTHOUGH OUTFLOW UNDERCUTTING THE STORMS
   HAS SOMEWHAT LIMITED THE LENGTH OF TIME TORNADOES CAN
   PERSIST...WHILE THOSE THAT CROSS INTO THE COOLER AIRMASS N OF THE
   FRONT QUICKLY DIMINISH IN INTENSITY. HOWEVER...A TORNADO THREAT WILL
   LIKELY CONTINUE OVER THE NEXT FEW HOURS...ESPECIALLY AS STORMS
   ENCOUNTER GREATER BUOYANCY NEAR THE FRONT.
