   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 460
   CONTINUES.

   SUMMARY...THREAT FOR DMGG WINDS AND LARGE HAIL WILL REMAIN MAXIMIZED
   IN A W-E ORIENTED BAND APPROACHING I-70 IN CNTRL KS. ADDITIONAL TSTM
   DEVELOPMENT/INTENSIFICATION REMAINS POSSIBLE FARTHER S INTO SERN KS
   OVER THE NEXT COUPLE HRS.

   DISCUSSION...LATEST RADAR TRENDS SHOW A NEARLY CONTINUOUS LINE OF
   STORMS EXTENDING FROM NESS COUNTY ESEWD INTO HARVEY COUNTY KS. THIS
   ACTIVITY IS LIKELY JUXTAPOSED WITH THE NOSE OF A 25-30 KT
   LLJ...WHICH IS SLOWLY LIFTING NWD TOWARDS I-70. FORECAST MODEL
   GUIDANCE INDICATES NWD PROGRESSION OF CONVECTION SHOULD SLOW IN THE
   NEXT FEW HRS...AND EVENTUALLY SPREAD EWD TOWARDS PORTIONS OF E-CNTRL
   KS. VERY MOIST BOUNDARY LAYER CONDITIONS /E.G. MID-70S DEWPOINTS F/
   WILL MAINTAIN THE POTENTIAL FOR DMGG WIND GUSTS AND LARGE HAIL...AS
   WELL AS VERY HEAVY RAINFALL. FARTHER S...CONVECTION IS LESS VIGOROUS
   GIVEN WEAKER FORCING FOR ASCENT...BUT AS AN ASSOCIATED OUTFLOW
   BOUNDARY CONTINUES TO SPREAD EWD INTO SERN KS AND MOIST ELY
   LOW-LEVEL INFLOW IS MAINTAINED...THE POTENTIAL FOR INTENSIFICATION
   WILL STILL EXIST.
