   AREAS AFFECTED...WESTERN KS
   
   CONCERNING...SEVERE THUNDERSTORM WATCH 187...
   
   VALID 190400Z - 190530Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 187
   CONTINUES.
   
   SEVERE TSTM WATCH 187 CONTINUES UNTIL 05Z...WITH DAMAGING
   WINDS/SEVERE HAIL THE PRIMARY CONCERNS. GIVEN THE SCHEDULED 05Z
   EXPIRATION OF WW 187...CURRENT THINKING IS THAT A REPLACEMENT WATCH
   AND/OR WFO EXTENSION WILL BE NEEDED WITHIN THE HOUR.
   
   A MIXED SEVERE CONVECTIVE MODE WILL LIKELY CONTINUE OVER THE NEXT
   COUPLE OF HOURS ACROSS WEST CENTRAL/SOUTHWEST KS. QUASI-DISCRETE
   SUPERCELLS...WITH A LARGE HAIL AND NON-ZERO TORNADO RISK...WILL
   CONTINUE MAINLY ACROSS SOUTHWEST KS AHEAD OF AN UPSCALE GROWING
   MCS/BOW ACROSS WEST CENTRAL KS. AIDED BY AN INCREASING
   SOUTH-SOUTHEASTERLY LOW LEVEL JET...CELL MERGERS SHOULD YIELD
   CONTINUED UPSCALE GROWTH/FORWARD PROPAGATION ESE-WARD ACROSS WEST
   CENTRAL/SOUTHWEST KS. WHILE THIS MCS WILL ENCOUNTER A MORE
   CONVECTIVE-HOSTILE BOUNDARY LAYER INTO CENTRAL KS...UPSCALE
   GROWTH/FORWARD PROPAGATION AND A SOUTHERLY LOW LEVEL INSTABILITY
   FEED INVOF RETREATING FRONTAL ZONE WILL SUPPORT DAMAGING WIND
   POTENTIAL.
