Areas affected...central and southwest Kansas into the Texas South
Plains

Concerning...Severe Thunderstorm Watch 202...

Valid 142255Z - 150030Z

The severe weather threat for Severe Thunderstorm Watch 202
continues.

SUMMARY...The potential for 60-75 mph wind gusts is expected to
continue through about 02 or 03z, before the boundary-layer starts
to stabilize.

DISCUSSION...As of 22:50Z, mosaic radar data shows widely scattered
to scattered, high-based thunderstorms ongoing from along and south
of U.S. 54 in southwest KS into the TX South Plains. The majority of
storms are occurring west of a diffuse dryline within a hot and
deeply mixed boundary layer with MUCAPE of 500-1000 J/kg. Area VWPs
indicate relatively weak deep-layer shear of generally less than 30
kt, which should limit the potential for storm
organization/longevity. Nonetheless, active cold pools and the
presence of a short-wave trough moving into western KS are likely to
support continued, multicellular and pulse-type storms capable of
60-75 mph wind gusts.

Overall storm coverage and intensity are expected to diminish by 02
or 03z as the boundary layer starts to cool and stabilize. A
possible exception is east of a Great Bend to Pratt, KS line where
weak, but existent convection is in close proximity to the dryline,
and a stronger capped, but more unstable environment. If storms can
become established east of the dryline, a potentially
longer-duration severe-weather threat could materialize as the
nocturnal low-level jet strengthens.
