Areas affected...eastern Colorado into western Kansas

Concerning...Severe Thunderstorm Watch 587...

Valid 170146Z - 170345Z

The severe weather threat for Severe Thunderstorm Watch 587
continues.

SUMMARY...Damaging wind potential may extend downstream of WW587.

DISCUSSION...A loosely organized cluster continues to drift
southeastward out of eastern Colorado this evening. There is some
uncertainty to the maintenance of this cluster downstream into
Kansas. Temperatures across western Kansas remain warm in the upper
70s to 80s with dew points in the low to mid 60s. 00z RAOB from DDC
sampled MLCAPE around 1100 J/kg but also fairly warm air around 700
mb. It is possible that with the loss of daytime heating, storms may
struggle with eastward extent given the warmer air aloft. This area
will be monitored but downstream watch issuance remains low
confidence at this time. Local watch extension of WW587 may be
needed.
