   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 133 CONTINUES.
   
   SEVERE/TORNADO THREAT HAS DIMINISHED ACROSS WW 133.  
   
   LATEST RADAR IMAGERY SHOWS AN INITIAL AREA OF RAIN/THUNDERSTORMS NOW
   MOVING ACROSS THE APPALACHIANS...LEAVING A RELATIVELY COOL/STABLE
   LOW-LEVEL AIRMASS IN ITS WAKE.  WHILE COLD AIR/STEEP LAPSE RATES
   ALOFT CONTINUE SPREADING ACROSS THIS REGION IN CONJUNCTION WITH THE
   UPPER CIRCULATION...ATTEMPTS AT CONVECTIVE REDEVELOPMENT BACK CLOSER
   TO THE COLD POOL HAVE BEEN WEAK -- LIMITED BY THE OVERALL LACK OF
   INSTABILITY.  EXPECT ANY REMAINING SEVERE POTENTIAL OVER VALID
   PORTIONS OF WW TO BE QUITE LIMITED.
