   Areas affected...southeast Colorado and portions of western Kansas

   Concerning...Severe Thunderstorm Watch 674...

   Valid 210724Z - 210830Z

   The severe weather threat for Severe Thunderstorm Watch 674
   continues.

   SUMMARY...The threat for severe weather is diminishing and the
   remaining valid portions of the watch may be cancelled prior to the
   09Z expiration.

   DISCUSSION...Recent trends in volumetric radar data indicate
   decreasing echo tops and updraft intensities owing to the presence
   of considerable convective inhibition and the resultant disruption
   of previous supercell structures. Ongoing storms over portions of
   Otero, Bent, and Prowers Counties in southeast CO may remain capable
   of locally gusty winds and sub-severe hail for the next hour or so.
   However, in general, the threat for organized severe weather appears
   to have ended.
