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.
