   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
   continues.

   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
   occurring.
