   Areas affected...northern and western Oklahoma and northwest Texas

   Concerning...Severe Thunderstorm Watch 165...

   Valid 302347Z - 010045Z

   The severe weather threat for Severe Thunderstorm Watch 165
   continues.

   SUMMARY...Severe threat continues within WW165.

   DISCUSSION...Thunderstorm activity continues near the surface
   dryline across northern and western Oklahoma into northwestern
   Texas, with periodic reports of large hail (up to 3 in) and a report
   of a tornado in southwestern Oklahoma. The dryline has receded
   westward in the last hour. Additional storm development will be
   possible over the next hour. The threat should gradually diminish by
   mid evening, though a few isolated supercells with a threat of very
   large hail, damaging winds, and a tornado are possible prior to this
   expected weakening. The tornado threat will be dependent on storm
   scale evolution of mergers and boundaries where surface vorticity
   can be maximized.
