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.
