Areas affected...Much of central/western Kansas...Oklahoma Panhandle
Concerning...Severe Thunderstorm Watch 192...
Valid 200233Z - 200430Z
The severe weather threat for Severe Thunderstorm Watch 192
continues.
SUMMARY...Severe threat continues across much of Severe Thunderstorm
Watch 0192. An additional Severe Thunderstorm Watch may be needed
downstream within the hour.
DISCUSSION...Earlier multicell clusters/transient supercells have
grown upscale into an MCS with two primary linear segments. One
segment is currently propagating east into northeast Kansas, with
the other segment moving southeast across southwest Kansas. Within
the last two hours, multiple reports of marginal severe wind gusts
have been received in association with both linear segments,
suggesting that damaging winds have become the predominant threat.
With effective bulk shear vectors oriented roughly perpendicular to
the linear segments, the MCS is expected to remain organized, with a
damaging wind threat continuing.
Large hail remains a concern for a supercell located in Texas
County, Oklahoma. Given adequate effective bulk shear/buoyancy and
0-3km helicity greater than 250 m2/s2, the severe hail threat may
continue for at least a few more hours.
As such, an additional Severe Thunderstorm Watch may be needed
downstream within the next hour.
