   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 100028Z - 100200Z
   
   DIURNALLY ENHANCED CONVERGENCE ALONG THE DRYLINE HAS AIDED RECENT
   CONVECTION AND ISOLATED HIGH-BASED THUNDERSTORMS OVER SWRN KS.  THIS
   ACTIVITY HAS DEVELOPED WITHIN A VERY STEEP LAPSE RATE
   ENVIRONMENT...BUT PWAT VALUES ARE NOT PARTICULARLY IMPRESSIVE WITH
   ROUGHLY .75 INCHES NOTED ACROSS THIS REGION.  WITH LLJ EXPECTED TO
   INCREASE ACROSS THE SRN PLAINS THESE UPDRAFTS MAY LINGER FOR THE
   NEXT FEW HOURS BUT OVERALL COVERAGE/INTENSITY DO NOT SUGGEST A WATCH
   WILL BE NEEDED AT THIS TIME.
