   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 214
   CONTINUES.
   
   A MARGINAL/LOCALIZED SVR THREAT CONTINUES ACROSS SVR WW 214. RECENT
   RADAR TRENDS INDICATE ISOLATED STRONG-SVR THUNDERSTORMS ARE ONGOING
   ACROSS PORTIONS ERN WV AND W-CNTRL VA. BOUNDARY LAYER MOISTURE
   REMAINS SUFFICIENT TO SUPPORT MARGINAL-MODERATE INSTABILITY...BUT
   WITH THE LOSS OF DIABATIC HEATING OVER THE NEXT FEW HRS...OVERALL
   THUNDERSTORM COVERAGE/INTENSITY IS EXPECTED TO DIMINISH. ONE
   EXCEPTION MAY BE ACROSS NRN PORTIONS OF THE WW AREA...WHERE A
   STRENGTHENING LLJ WILL LIKELY SUPPORT ADDITIONAL CONVECTION.
   ALTHOUGH NOT CURRENTLY ANTICIPATED...TRENDS WILL CONTINUE TO BE
   MONITORED SHOULD A LOCAL EXTENSION IN TIME OR A NEW WW BE REQUIRED
   ACROSS THIS AREA AFTER 01Z.
