Areas affected...north-central Oklahoma into southwest Missouri and
northwest Arkansas

Concerning...Severe Thunderstorm Watch 140...

Valid 240450Z - 240645Z

The severe weather threat for Severe Thunderstorm Watch 140
continues.

SUMMARY...A corridor of damaging wind, hail, and brief tornado
potential persists from north-central into northeast Oklahoma, and
eventually into southwest Missouri and northwest Arkansas.

DISCUSSION...Earlier supercells have largely merged into a
linear/bowing structure this evening, with aggregating outflows and
a cold front pushing in from the north. While the surface air mass
has become cooler, substantial instability remains for elevated
parcels feeding into this system. Strong low-level shear exists with
50-60 kt at or above 925 mb, which will continue to feed this
complex.

Deep-layer shear is generally parallel to the orientation of this
line, however, periodic bowing structures may persist across the
area, with mesocyclones still possible. Damaging gusts, areas of
hail, and even a brief tornado cannot be ruled out next several
hours given such strong shear and ample moisture/instability.
