   AREAS AFFECTED...ERN/SRN WV...SWRN/WRN VA...WRN CAROLINAS AND NRN GA
   
   CONCERNING...SEVERE POTENTIAL...WATCH LIKELY 
   
   VALID 141750Z - 141845Z
   
   TSTMS WILL CONTINUE TO DEVELOP AND INCREASE IN COVERAGE/INTENSITY
   ALONG AND IN ADVANCE OF A COLD FRONT...NOW MOVING INTO THE CENTRAL
   AND SRN APPALACHIANS.  A SEVERE TSTM WATCH MAY BE NEEDED IN LEE OF
   THE MOUNTAINS FROM WRN/CENTRAL VA SWWD THROUGH THE WRN CAROLINAS TO
   PART OF NERN GA.
   
   EARLY AFTERNOON SURFACE ANALYSIS SHOWED AN AREA OF LOW PRESSURE
   CENTERED OVER NERN OH WITH A COLD FRONT TRAILING SWWD THROUGH WRN
   WV...ERN KY...ERN TN TO CENTRAL AL.  AIR MASS ALONG AND E OF THE
   FRONT HAS BECOME MODERATELY UNSTABLE...WITH REGIONAL RADAR IMAGERY
   INDICATING CONVECTION/STORMS DEVELOPING ALONG THE COLD FRONT AND
   ADDITIONAL STORMS INCREASING IN INTENSITY AS THEY MOVE OFF THE
   HIGHER TERRAIN INTO STRONGER INSTABILITY OVER NERN GA/WRN SC. 
   OBJECTIVE ANALYSES INDICATED STRONGER WINDS ROUNDING THE BASE OF THE
   MID/UPPER LEVEL TROUGH INTO THE SRN APPALACHIANS REGION RESULTING IN
   AN INCREASE IN DEEP LAYER SHEAR OF 30-35 KT /SUPPORTIVE OF
   MULTICELLS AND LINE SEGMENTS/.
   
   TSTMS SHOULD INCREASE IN COVERAGE AS THE COLD FRONT CRESTS AND MOVES
   IN LEE OF THE HIGHER TERRAIN FROM WRN VA TO NERN GA.  FURTHER
   DESTABILIZATION AND SUFFICIENT DEEP LAYER SHEAR SUPPORT A THREAT FOR
   ADDITIONAL STRONGER TO SEVERE STORMS THIS AFTERNOON.
