   Areas affected...southeastern Wyoming into western Nebraska
   Panhandle

   Concerning...Severe Thunderstorm Watch 289...

   Valid 082339Z - 090045Z

   The severe weather threat for Severe Thunderstorm Watch 289
   continues.

   SUMMARY...Severe threat continues within WW289.

   DISCUSSION...A line of thunderstorm activity continues across
   southeastern Wyoming, with occasional stronger cores with potential
   for large hail and strong to severe wind. Local enhancement of
   surface vorticity near a diffuse boundary across northern Laramie
   County may promote some increase in landspout potential in the short
   term. Storms should eventually move downstream in western Nebraska
   Panhandle this evening, with potential for damaging wind.
