   Areas affected...far northeast CO...northwest KS...southwest NE

   Concerning...Severe Thunderstorm Watch 366...

   Valid 132341Z - 140145Z

   The severe weather threat for Severe Thunderstorm Watch 366

   SUMMARY...Severe gusts ranging from 60-80 mph and large hail are
   possible through 02 UTC.

   DISCUSSION...A broken band of primarily discrete thunderstorms is
   developing across the eastern-most tier of counties in northeast CO
   and into southwest NE early this evening.  Surface analysis
   indicates a gradual increase in low-level moisture with farther east
   extent and 23 UTC observations show upper 50s dewpoints near the
   storms whereas McCook, NE dewpoints are in the middle to upper 60s. 
   Ample high-level flow will aid in maintaining storm
   venting/organization as the thunderstorm activity gradually
   encounters a more moisture-rich boundary layer and larger CAPE
   during the 01-03 UTC period.  Expecting additional storm development
   and upscale growth to occur over the next few hours with storms
   generally reaching a Colby to McCook line near 02 UTC.  Severe gusts
   will become the primary hazard once storms grow upscale but large
   hail will be possible prior to this convective mode transition
