   Areas affected...eastern Colorado/Wyoming into western Kansas

   Concerning...Severe Thunderstorm Watch 584...

   Valid 152308Z - 160115Z

   The severe weather threat for Severe Thunderstorm Watch 584
   continues.

   SUMMARY...Severe threat continues within WW584.

   DISCUSSION...Several clusters of storms and a few more isolated
   supercells continue within WW584. A supercell near Denver had
   reports of 64 mph winds and hail up to 1.75 inches in diameter.
   Large hail and damaging wind will continue to be possible with
   supercells through the early evening, given moderate instability and
   35-45 kts of effective shear. With cell interactions, mode is
   gradually shifting to become more clustered/multi-cell this evening.
   Guidance suggests that one or more clusters may evolve eastward into
   western Kansas through the evening. 

   Downstream across western Kansas, steep low to mid-level lapse
   rates, temperatures in the mid 80s to low 90s F, and dew points in
   the upper 60s to 70s are supporting moderate to strong instability,
   though lingering inhibition remains. Should a cluster be able to
   organize along a cold pool and shift eastward, damaging wind
   potential may increase into the evening. A downstream watch will
   probably be needed into western Kansas later this evening.
