   Areas affected...northwest Kansas...far east Colorado...and
   south-central Nebraska

   Concerning...Severe Thunderstorm Watch 343...

   Valid 082251Z - 082345Z

   The severe weather threat for Severe Thunderstorm Watch 343

   SUMMARY...The severe thunderstorm threat will continue.
   Thunderstorms are developing/continuing along a surface cold front
   across Nebraska. Additional thunderstorms have developed farther
   south in parts of northwest Kansas. The large-scale environment will
   continue to support a severe potential into the evening.

   DISCUSSION...A surface-cold front continues to move south and east
   this evening. Convergence along this front has allowed for the
   development and maintenance of several severe thunderstorms across
   southern Nebraska, with additional thunderstorms along a myriad of
   surface boundaries in northwest Kansas. Mixed-layer CAPE around 3000
   J/kg and deep-layer shear around 30-40 knots along and ahead of
   these storms will maintain an environment supportive of severe
   thunderstorms capable of producing gusty winds and large hail.
   Additionally, sufficient combination of 0-3km CAPE values and
   surface vorticity in the region will support the potential for a
   landspout or two with any vigorous updraft that persists atop any
   surface boundary. Additionally as thunderstorms from the northern
   cluster (Lincoln County, NE) interact with thunderstorms from the
   southern cluster (Hayes County, NE) an increase in the potential for
   all severe modes may briefly occur.
