Areas affected...Eastern KS...Western/Central MO...Northeast OK

Concerning...Severe Thunderstorm Watch 89...91...

Valid 150015Z - 150145Z

The severe weather threat for Severe Thunderstorm Watch 89, 91
continues.

SUMMARY...The risk for scattered severe thunderstorms continues
across WW 89. Some threat may extend outside of the watch into
northeast OK and southwest MO.

DISCUSSION...Scattered severe thunderstorms continue across portions
of eastern KS and western MO at 00Z. The strongest storm is
affecting Cowley County KS, with very large hail and at least one
tornado reported within the last hour. This storm is beginning to
move southeastward into northern OK, and the severe threat will
likely spread into the far northeast part of WW 91, and also into
Osage County OK, where no watch is in effect. Given the isolated
nature of the storm and its relatively slow movement, downstream
watch issuance is not anticipated in the short term across northeast
OK. 

Further east, a couple of small bowing segments have developed over
western/central MO, one northwest of Springfield and the other west
of Columbia. Some damaging wind threat will exist in the short term
with these bowing segments, though a weakening trend is expected
this evening, given relatively weak midlevel flow/effective shear
(as noted on 00Z SGF sounding) and increasing SB CINH. 

Elsewhere across WW 89, storms will likely continue into at least
mid-evening, with redevelopment possible on various outflows across
the region, though a gradual decreasing trend is expected as diurnal
cooling commences.
