   Areas affected...Part of eastern KS and western MO

   Concerning...Severe Thunderstorm Watch 109...

   Valid 200041Z - 200215Z

   The severe weather threat for Severe Thunderstorm Watch 109
   continues.

   SUMMARY...A stabilizing environment across the remaining portion of
   WW 109 (south of I-70) should result in additional counties being
   canceled from the watch or an overall early cancellation of the rest
   of WW 109 are possible.

   DISCUSSION...An extensive cirrus shield that expanded poleward from
   the complex of storms that spread from southeast KS into southwest
   and central MO late afternoon and early evening has stabilized much
   of the environment across WW 109.  Although pockets of instability
   remain near the cold front, which extended from eastern IA through
   northwest MO and northeast KS to northwest OK, increasing
   surface-based inhibition should continue to limit the development of
   strong updrafts.  Meanwhile, a cluster of storms located over
   central MO at 0030Z will advance further away from the southeast
   portion of WW 109, precluding a severe-weather threat in this part
   of the watch.
