   SPORADIC POCKETS OF WIND DAMAGE WILL PERSIST INTO THE EVENING HOURS
   ACROSS THE CAROLINA PIEDMONT AND SERN VA.  LOOSE LINEAR CONGLOMERATE

   LOOSE CONGLOMERATE OF STORMS ACROSS THE CAROLINA PIEDMONT AND
   S-CNTRL VA FROM RIC TO THE UPSTATE OF SC.  THERE WAS A RECENT
   MEASURED GUST OF 43 KTS AT KSFQ /SUFFOLK VA/.  STRONG SURFACE
   HEATING E OF THE LINEAR STORM CLUSTER HAS RESULTED IN TEMPS RISING
   WELL INTO THE 90S IN MOST LOCATIONS WITH SURFACE T/TD SPREADS AROUND
   30 DEG F AND A STEEP LOW LEVEL LAPSE RATE ENVIRONMENT.  KRAX VAD
   SHOWS WEAK WLY TROPOSPHERIC FLOW FAVORING AN EWD STORM MOTION OF
   AROUND 15 KTS.  THE CONSOLIDATED EWD MOVING COLD POOL WITH THE
   LINEAR STORM CONGLOMERATE WILL LIKELY CONTINUE TO POSE A
   STRONG-PERHAPS SEVERE DOWNDRAFT RISK...WITH POCKETS OF SPORADIC WIND
   DAMAGE THE RESULT.  AS SUCH...A LOCAL EXTENSION-IN-AREA MAY BE
   WARRANTED FOR PORTIONS OF THE NC PIEDMONT/COASTAL PLAIN OR A NEW WW
