   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.
