    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.
