Areas affected...portions of western into central Kansas

Concerning...Severe Thunderstorm Watch 359...361...

Valid 210424Z - 210600Z

The severe weather threat for Severe Thunderstorm Watch 359, 361
continues.

SUMMARY...Severe gusts will remain a concern with the ongoing MCS
for at least the next few hours.

DISCUSSION...A mature cold-pool-driven MCS continues to propagate
southeastward across western into central KS, with several recent
measured severe gusts noted. Recent KICT inbound velocity data shows
that a pronounced rear-inflow jet persists with this MCS, as well as
a book-end/line-end mesovortex on its northern flank. Furthermore,
this MCS will continue to progress southeastward amid a highly
sheared and buoyant airmass, characterized by 50 kts of effective
bulk shear (oriented roughly normal to the MCS leading line) and
2000+ J/kg MLCAPE, driven by 8+ C/km mid-level lapse rates. Given
the highly organized storm structure and favorable ambient
supporting environment, severe gusts will likely continue with this
MCS for at least a few more hours.
