   Areas affected...The High Plains of Colorado and the Nebraska
   Panhandle

   Concerning...Severe Thunderstorm Watch 350...

   Valid 292255Z - 300100Z

   The severe weather threat for Severe Thunderstorm Watch 350
   continues.

   SUMMARY...Scattered strong to severe thunderstorms will continue to
   pose a threat of severe damaging wind gusts, marginally severe hail,
   and possibly a land spout or two.

   DISCUSSION...A few clusters of robust updrafts continue to slowly
   progress eastward off the higher terrain of the NE Panhandle and
   eastern CO plains. These thunderstorms developed within a lee
   surface trough/dryline, within an environment characterized by very
   steep mid and low-level lapse rates, relatively weak deep layer
   shear, and enhanced surface vorticity. The latter, and localized
   pockets of enhanced stretching, will continue to support non-zero
   probabilities for landspouts. In addition, as the evening
   progresses, continued cell mergers combined with inverted V
   soundings/large downdraft CAPE could promote severe wind gusts via
   wet downbursts. Before then, isolated hail stones up to 1-1.75" in
   diameter will remain possible.
