   Concerning...Severe Thunderstorm Watch 353...

   Valid 110000Z - 110100Z

   The severe weather threat for Severe Thunderstorm Watch 353
   continues.

   SUMMARY...The ongoing small cluster of severe storms across southern
   portions of WW353 will likely exit the watch within the next 60
   minutes. Additional local extensions may be needed given the
   possibility for severe wind gusts for the next few hours.

   DISCUSSION...The small cluster of storms over southern Nebraska has
   produced several reports of wind damage and severe wind gusts over
   the last several hours. Most recently, a Nebraska mesonet station
   near Kearney recorded a gust to 61 mph at 2320 UTC. These storms are
   ongoing in an environment characterized by 2000-3000 J/kg of MUCAPE
   and 40-50 kt of effective shear which will likely continue to
   support updraft development and organization. Downstream of the
   ongoing storms, buoyancy is weaker from earlier convection, which
   suggests some uncertainty on storm longevity later this evening.
   However, it appears likely that these storms will continue to pose a
   threat for severe wind gusts for at least a few more hours as they
   move into portions of north/central Kansas. Additional local
   extensions, and or a downstream watch maybe needed depending on
   convective trends.
