Areas affected...Southwest Kansas

Concerning...Severe Thunderstorm Watch 250...

Valid 310148Z - 310245Z

The severe weather threat for Severe Thunderstorm Watch 250
continues.

SUMMARY...A local corridor of greater severe wind gusts potential
has developed near Scott City. This activity will continue to the
southeast over the next couple hours. SPC has coordinated with WFO
DDC to extend WW 250 southeastward.

DISCUSSION...A mesoscale circulation has develop as convection along
a boundary in northwest Kansas has merged with convection moving
east out of Colorado. Recent severe wind gusts of 65-70 mph have
been measured in Scott County with this activity. The 00Z observed
DDC sounding did show steep mid-level lapse rates, but also some
MLCIN. With some boundary-layer cooling having already occurred,
there is at least some uncertainty how far southeastward this
complex will progress. Given the MCV and strong cold pool (Scott
City ASOS showed drop from 82 to 66 as the storms passed), it seems
plausible that severe wind gusts will continue for some distance
downstream.
