   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 
   
   VALID 282044Z - 282145Z
   
   THE POTENTIAL FOR A FEW SEVERE TSTMS CAPABLE OF ISOLATED DAMAGING
   WINDS MAY CONTINUE INTO THIS EVENING ACROSS DISCUSSION AREA. 
   CONVECTIVE TRENDS ARE BEING MONITORED FOR A POSSIBLE WW.
   
   A SHORT BAND OF TSTMS HAS RECENTLY DEVELOPED ALONG COLD FRONT FROM N
   OF DAN TO SW OF GSO.  AMBIENT AIR MASS OVER THE PIEDMONT IS RATHER
   WARM AND MOIST...BUT POOR MIDLEVEL LAPSE RATES ARE EFFECTIVELY
   LIMITING MLCAPE TO LESS THAN 500-700 J/KG.  WHILE WIND FIELD BELOW 1
   KM IS GENERALLY LESS THAN 20-25 KT...NOTABLE STRENGTHENING TO 40-50
   KT IS CURRENTLY BEING OBSERVED AROUND 2 KM...PER AREA VWPS.  GIVEN
   THE RELATIVELY STEEP LOW-LEVEL LAPSE RATES IN PLACE...SOME POTENTIAL
   FOR STRONG WIND GUSTS WILL EXIST WITH THE MORE INTENSE STORMS.  THIS
   THREAT SHOULD BEGIN TO DIMINISH LATER THIS EVENING AS THE BOUNDARY
   LAYER STARTS TO COOL/STABILIZE.
