Areas affected...Parts of southeastern Colorado and southwestern
Kansas

Concerning...Severe Thunderstorm Watch 450...

Valid 140213Z - 140345Z

The severe weather threat for Severe Thunderstorm Watch 450
continues.

SUMMARY...Areas of watch 450 to the north of the Texas Panhandle
could be cancelled early.

DISCUSSION...A corridor of moderate to strong potential boundary
layer instability lingers within lee surface troughing across the
region, but inhibition for near surface parcels is increasing with
the loss of daytime heating.  Given the lack substantive low-level
jet strengthening or other obvious forcing for large-scale ascent,
the ongoing cluster of thunderstorms now slowly developing
southeastward near the Colorado/Kansas border (to the southwest of
Goodland) seems unlikely to pose an appreciable severe risk beyond
another hour or so.
