   Concerning...Severe Thunderstorm Watch 372...

   Valid 220821Z - 221015Z

   The severe weather threat for Severe Thunderstorm Watch 372
   continues.

   SUMMARY...Damaging thunderstorm winds will remain possible as a
   well-developed bowing complex of severe storms continues to move
   east/southeast. The severe risk will likely extend beyond WW 372
   after 09-10z, and a downstream watch will be needed.

   DISCUSSION...A long-lived and mature bow echo continues to move
   east/southeast at around 45 mph across southern/eastern OK as of
   0820z. Numerous reports of severe wind gusts have been received
   during the early morning across OK, with the most recent reports
   generally in the 60 to 70 mph range. Aided by a well-developed cold
   pool, evidenced by a 7 mb pressure rise at the Norman mesonet as the
   system moved through central Oklahoma, severe wind gusts in the 60
   to 70 mph range, with isolated higher gusts, will remain likely as
   the leading edge approaches the southern/eastern edges of WW 372 in
   the 09-10z time frame. Given the well-organized structure of the MCS
   and a favorable downstream thermodynamic environment (MUCAPE
   averaging 3000 J/kg), the severe wind risk is expected to move into
   western AR/northeast TX, and a downstream Severe Thunderstorm Watch
   will be coordinated.
