   Areas affected...north-central Kansas and south-central Nebraska

   Concerning...Severe Thunderstorm Watch 343...

   Valid 090143Z - 090315Z

   The severe weather threat for Severe Thunderstorm Watch 343
   continues.

   SUMMARY...Severe thunderstorms persist across portions of northwest
   Kansas into south-central Nebraska. These thunderstorms will
   continue into the evening, and may eventually move out of the
   current Severe Thunderstorm Watch. As such, portions of Severe
   Thunderstorm Watch #343 may need to be replaced by a new watch, with
   additional watches farther south later this evening.

   DISCUSSION...Thunderstorms continue to develop along and near a
   south-ward moving surface-cold front across portions of central
   Nebraska. Additional thunderstorms are ongoing across portions of
   northwest Kansas, where an isolated supercell thunderstorm remains
   nearly stationary as it backbuilds along the front. 

   Large-scale environment across northwest Kansas into south-central
   Nebraska remains conducive for severe thunderstorms this evening as
   mixed-layer CAPE remains in excess of 2000 J/kg and deep-layer shear
   remains greater than 30 knots. As such, thunderstorms should
   continue past the expiration of Severe Thunderstorm Watch #343.
   Additionally a thunderstorm cluster across far south-central
   Nebraska may also exit the watch. Thus, northern portions of this
   Severe Thunderstorm watch will likely be replaced by a new watch
   soon, with additional watches possible farther south across portions
   of southwest Kansas later this evening.
