   CU FIELD IS EXPANDING/DEEPENING OVER THE HIGHER TERRAIN OF WRN VA
   AND WV.  THIS LIKELY IS A REFLECTION OF STEEPER LAPSE RATE
   ENVIRONMENT THAT HAS DEVELOPED DUE TO INTENSE HEATING AND SBCAPE
   VALUES NOW REFLECT VALUES ON THE ORDER OF 1500-3000 J/KG BENEATH
   MODESTLY STRONG SWLY DEEP LAYER FLOW.  UPSTREAM...CONVECTION IS
   GRADUALLY INTENSIFYING ACROSS PARS OF KY/ERN TN AND WILL SOON SPREAD
   INTO THE REGION MENTIONED.  GIVEN THIS EVOLUTION IT WOULD APPEAR
   THAT DAMAGING WINDS COULD CERTAINLY BE NOTED WITH STRONGER LINE
   SEGMENTS OR BOW-TYPE STRUCTURES.  WW WILL LIKELY BE ISSUED.
