   Areas affected...Eastern OK

   Concerning...Severe Thunderstorm Watch 392...

   Valid 040123Z - 040230Z

   The severe weather threat for Severe Thunderstorm Watch 392
   continues.

   SUMMARY...Downstream of WW 392, an additional severe thunderstorm
   watch will likely be issued as an MCS shifts southeast from central
   OK.

   DISCUSSION...00Z Lamont and Norman soundings sampled large buoyancy
   with MLCAPE of 3000-3500 J/kg ahead of a southeastward moving MCS
   across north-central to west-central OK. With an MCV near Enid and
   composite outflow surging southeast amid modest westerly upper-level
   flow, organized storm structures should persist the rest of the
   evening. A cooler boundary-layer relative to farther west within WW
   392 may limit widespread severe gusts in eastern OK. But the setup
   should yield a risk for strong to isolated severe wind gusts, along
   with embedded severe hail.
