   SEVERE THUNDERSTORMS PRIMARILY CAPABLE OF PRODUCING LARGE HAIL AND
   LOCALLY DMGG WINDS ARE GRADUALLY PROGRESSING SEWD INTO N CNTRL
   NC...AND MAY CONTINUE OVER THE NEXT FEW HOURS. HOWEVER...GIVEN
   SOMEWHAT ISOLATED COVERAGE...A WW MAY NOT BECOME NECESSARY.
   
   WEDGE FRONT HAS REMAINED NEARLY STATIONARY OVER NERN NC WWD THROUGH
   MUCH OF CNTRL NC. A WEAK UPPER WAVE OBSERVED ON WV IMAGERY OVER WV
   SWD THROUGH NRN AL HAS ALLOWED A SUBTLE WARM ADVECTION REGIME TO
   MAINTAIN THE SEVERITY OF CONVECTION N OF THE WEDGE FRONT...DESPITE
   THE ONSET OF RADIATIONAL COOLING. 00Z GSO SOUNDING INDICATES WEAK
   INSTABILITY EAST OF THE APPALACHIANS...WHICH MAY IMPEDE STRONGER AND
   MORE WIDESPREAD DEVELOPMENT. HOWEVER...STRONG WLY WINDS HAVE ALLOWED
   AN EML TO SPREAD TO THE CAROLINAS...WITH STEEP MID LEVEL LAPSE RATES
   AND STRONG DEEP-LAYER WIND PROFILES SUPPORTING LARGE HAIL IN ANY
   ELEVATED STORMS THAT CAN DEVELOP. AN ISOLATED TORNADO CANNOT BE
   RULED OUT IN CLOSER PROXIMITY TO THE WEDGE FRONT.
