Areas affected...Central and western Kansas into far southeast
Colorado

Concerning...Severe Thunderstorm Watch 357...

Valid 202318Z - 210115Z

The severe weather threat for Severe Thunderstorm Watch 357
continues.

SUMMARY...Large hail remains likely mainly over western Kansas and
into far southeastern Colorado, with isolated damaging wind gusts.
Isolated hail may eventually spread eastward across north central
Kansas.

DISCUSSION...Numerous storms are currently ongoing across western
KS, with several strong to severe also extending southwestward into
southeast CO. Veering winds in the low-levels beneath northwest flow
aloft will continue to support mainly southward-moving cells, with
some supercell potential resulting in large hail and strong wind
gusts. New cell generation has been noted recently over northwest
Kansas, but these cells are unlikely to pose more than a marginal
threat due to outflow to the south.

A few of the storms near Hays/Russell are merging and may post a
wind/hail threat across central KS. However, the far eastern rows of
counties including the I-35 corridor, and south-central KS may not
see much storm activity due to increasing CIN this evening.
Therefore, it is possible that extreme eastern portions of the watch
may be canceled early.
