Concerning...Severe Thunderstorm Watch 361...362...



Valid 210736Z - 210930Z



The severe weather threat for Severe Thunderstorm Watch 361, 362

continues.



SUMMARY...An isolated threat severe wind gusts and hail may continue

across parts of southern and eastern Kansas early this morning. The

threat may also impact far northern Oklahoma and far western

Missouri.



DISCUSSION...An MCS is ongoing across much of Kansas, along the

northern edge of a moist and unstable airmass. Moderate instability

is analyzed ahead of and to the south of the MCS with the RAP

showing MLCAPE from 1000 J/kg in eastern Kansas to 2500 J/kg in

north-central Oklahoma. The instability, along with large-scale

ascent associated with a mid-level shortwave trough over the 

central Plains, will continue to support the MCS for much of the

morning. Regional WSR-88D VWPs in northeast Oklahoma and

south-central Kansas have 0-6 km shear in the 35 to 40 knot range

suggesting that the stronger embedded cells could be supercellular

and have some severe potential. Hail will be possible with

supercells. Severe wind gusts will likely be concentrated along

short bowing line segments. Recently, the MCS has become less

organized. This trend could continue as inhibition increases,

resulting in a more isolated and marginal severe threat with time.
