   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 384
   CONTINUES.
   
   SEVERE TSTM WATCH 384 CONTINUES UNTIL 10Z ACROSS PORTIONS OF
   SOUTHWEST KS. PRIMARY POTENTIAL CONTINUES TO BE LARGE HAIL...WITH
   DAMAGING WINDS AND PERHAPS A BRIEF TORNADO POSSIBLE AS WELL.
   
   LONG LIVED SUPERCELL WITH HISTORY OF LARGE HAIL CONTINUES TO
   STEADILY PROGRESS EAST-SOUTHEASTWARD ACROSS STANTON/HAMILTON
   COUNTIES KS AS OF 04Z. LOW LEVEL SOUTHEASTERLY FLOW IN THE LOWEST 1
   KM HAS NOTABLY INCREASED AHEAD OF THIS SUPERCELL OVER THE PAST 1-2
   HOURS PER TRENDS IN DODGE CITY WSR-88D VWP DATA. RATHER FAVORABLE
   WIND PROFILES WITH 50+ KT OF EFFECTIVE SHEAR AND AMPLE LOW LEVEL
   HELICITY WILL CONTINUE TO SUPPORT UPDRAFT ROTATION/SUPERCELL
   MAINTENENCE...WITH LARGE HAIL AS THE PRIMARY THREAT. IN SPITE OF
   RATHER FAVORABLE WIND PROFILES FOR LOW LEVEL ROTATION...A
   CONTINUALLY COOLING NOCTURNAL BOUNDARY LAYER AND AMPLE SURFACE BASED
   CINH SHOULD KEEP ANY TORNADO THREAT BRIEF IN NATURE.
