   VALID 080058Z - 080200Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 29
   CONTINUES.

   SUMMARY...THE SEVERE THREAT ACROSS WW 29 IS DECREASING. THE WATCH
   MAY BE ABLE TO BE CANCELED EARLY IF CURRENT RADAR TRENDS CONTINUE.

   DISCUSSION...AS THE LINE OF THUNDERSTORMS THAT PRODUCED PERIODIC
   BOUTS OF DAMAGING WINDS ACROSS CNTRL KY MOVES EWD INTO ERN KY...IT
   IS ENCOUNTERING AN INCREASINGLY HOSTILE THERMODYNAMIC ENVIRONMENT AS
   SFC TEMPERATURES COOL AND LOW-LEVEL MOISTURE BECOMES MORE LIMITED. A
   CORRESPONDING DECREASE IN REFLECTIVITY SIGNATURES AND ECHO TOPS FROM
   AREA RADARS CONFIRMS THIS WEAKENING TREND. A SUPERCELL THUNDERSTORM
   THAT HAD FORMED AHEAD OF THE LINE HAS BECOME ABSORBED INTO A LARGE
   AREA OF STRATIFORM RAIN...AND HAS RECENTLY LOST ITS SUPERCELL
   CHARACTERISTICS. A MARGINAL DAMAGING WIND THREAT PERSISTS ACROSS SRN
   PORTIONS OF WW 29 AS A SMALL BOW ECHO WITH EMBEDDED ROTATION MOVES
   EWD NEAR THE KY/TN BORDER. IF CURRENT RADAR TRENDS CONTINUE OVER THE
   NEXT HOUR...WW 29 MAY BE CANCELED EARLY.
