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.
