   Areas affected...Extreme northwest Texas and southwest Oklahoma

   Concerning...Severe Thunderstorm Watch 393...396...

   Valid 260354Z - 260500Z

   The severe weather threat for Severe Thunderstorm Watch 393, 396
   continues.

   SUMMARY...Isolated severe gusts will be possible through about 05z
   across far northwest Texas and southwest Oklahoma.  WW #393 will be
   allowed to expire at 04z.

   DISCUSSION...The primary threat for severe storms with 60+ mph
   outflow gusts is now confined to far southwest OK and northwest TX,
   where outflow interactions are occurring.  Storm/outflow mergers
   will lead to temporary strengthening of updrafts and subsequent
   downdrafts in an environment of lingering moderate buoyancy and
   steep lapse rates.  However, the longer term trend should be for
   gradual storm weakening and a reduction in the severe threat by and
   after about 05z.
