   northwest Kansas

   Concerning...Severe Thunderstorm Watch 262...

   Valid 020023Z - 020200Z

   The severe weather threat for Severe Thunderstorm Watch 262
   continues.

   SUMMARY...Severe thunderstorms will continue moving east across the
   area this evening. A new watch will likely be needed east of Severe
   Thunderstorm Watch #262.

   DISCUSSION...Multiple clusters of severe thunderstorms continue
   across Severe Thunderstorm Watch #262 this evening. One such cluster
   is moving east across the Nebraska panhandle. This cluster has a
   history of producing hail around 1" and a brief tornado. To the
   south, another cluster of storms is moving east across northeast
   Colorado into northwest Kansas. This cluster also has a history of
   producing severe reports, with a 1" hail report noted near Yuma, CO.
   These storms are ongoing within a favorable environment for severe
   storms, with MUCAPE around 500-1000 J/kg (increasing to greater than
   1500 J/kg ahead of the storms) and effective-layer shear on the
   order of 40-50 knots. 

   These storms should continue moving east and may eventually grow
   upscale and merge into a linear system as it moves east out of the
   Severe Thunderstorm Watch. As such, a new watch will likely be
   needed east of Watch #262.
