   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 66
   CONTINUES.
   
   SUMMARY...LOCALIZED/MARGINAL SEVERE HAIL/WIND THREAT WILL PERSIST
   WITH A SEWD-SAGGING TSTM CLUSTER ALONG THE SERN KS/SWRN MO BORDER.
   PROSPECT FOR ADDITIONAL TSTM DEVELOPMENT FARTHER W/NW WITHIN THE WW
   PRIOR TO 03Z EXPIRATION APPEARS SLIM.
   
   DISCUSSION...RECOVERY/DESTABILIZATION HAS BEEN OCCURRING IN THE WAKE
   OF EARLY DAY CONVECTION ACROSS THE OZARK PLATEAU. CONVERGENCE ALONG
   THE CONVECTIVE OUTFLOW SHOULD SUPPORT CONTINUED REGENERATION ALONG
   THE SRN/WRN FLANK OF THE CLUSTER WITHIN A BROADER SEWD MOVEMENT.
   GIVEN THE CONVECTIVE MODE AND ENVIRONMENT...THE INTENSITY/COVERAGE
   OF EITHER HAIL/WIND SHOULD REMAIN MARGINAL. FARTHER TO THE
   W/NW...CONVERGENCE ALONG THE SURFACE TROUGH APPEARS WEAK WITH
   PREDOMINATELY N/NWLY SURFACE WINDS EXISTING AHEAD OF THE COLD FRONT
   APPROACHING FROM ALONG THE KS/NEB BORDER. RELATIVELY FLAT CU FIELD
   AND LACK OF STRONGER LARGE-SCALE ASCENT SUGGESTS ADDITIONAL TSTM
   DEVELOPMENT AWAY FROM THE CLUSTER IS UNLIKELY.
