   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 269
   CONTINUES.
   
   ISOLATED SEVERE THUNDERSTORMS HAVE DEVELOPED ACROSS PARTS OF
   WW269...PRIMARILY ALONG THE NC/SC BORDER.  THIS ACTIVITY HAS EVOLVED
   WITHIN A MODERATELY UNSTABLE AIRMASS THAT IS MORE THAN ENOUGH
   SHEARED TO SUPPORT ORGANIZED ROTATING UPDRAFTS.  ONE OR MORE MINOR
   DISTURBANCES MAY BE EMBEDDED WITHIN DEEP NWLY FLOW FROM THE OH
   VALLEY INTO THE CAROLINAS...HOWEVER WEAK WARM ADVECTION MAY
   PARTIALLY EXPLAIN THE ELONGATED ZONE OF CONVECTION THAT STRETCHES
   NW-SE ALONG THE FRONT SIDE OF RIDGE AXIS.  GIVEN THE BROADER ZONE OF
   WARM ADVECTION AND MOIST/BUOYANT NWLY INFLOW...IT APPEARS NEW
   CONVECTION MAY EVOLVE UPSTREAM WELL INTO THE EVENING HOURS.
