Areas affected...portions of southwestern Kansas...Oklahoma and
Texas Panhandles...northwestern Oklahoma

Concerning...Severe Thunderstorm Watch 367...368...371...

Valid 220336Z - 220430Z

The severe weather threat for Severe Thunderstorm Watch 367, 368,
371 continues.

SUMMARY...Numerous additional 50+ kt convective gusts are expected
with an approaching MCS over the next few hours. A few gusts could
exceed 75 mph.

DISCUSSION...A cold-pool-driven MCS, with a history of numerous
measured 50+ kt gusts, continues to propagate southeast into a
highly unstable/sheared airmass. KVNX inbound velocity data depicts
a descending rear-inflow jet at the apex of a bowing structure
embedded within the MCS, which should serve as the impetus for
numerous additional 50+ kt gusts over the next few hours,
particularly over northwestern OK. Given the highly organized MCS
structure interacting with such a favorably destabilized/sheared
environment, a few gusts may exceed 75 mph.
