   SUMMARY...A band of severe thunderstorms initially over Oklahoma

   the watch area this evening into tonight.  Severe downdraft winds
   will be a distinct hazard, with isolated gusts near hurricane force

   parts of north Texas.  A line-embedded tornado or two cannot be
   ruled out as well.

   The severe thunderstorm watch area is approximately along and 105
   statute miles either side of a line from 55 miles southwest of
   Stephenville TX to 45 miles east southeast of Texarkana AR. For a
   complete depiction of the watch see the associated watch outline
   update (WOUS64 KWNS WOU4).
