    Areas affected...Southern Nebraska...northern and western Kansas

    Concerning...Severe Thunderstorm Watch 192...

    Valid 192312Z - 200115Z

    The severe weather threat for Severe Thunderstorm Watch 192
    continues.

    SUMMARY...Severe threat continues across Severe Thunderstorm Watch
    0192. Large hail will likely be the main threat along with isolated
    damaging wind gusts.

    DISCUSSION...Multicell clusters are in progress across much of the
    area under Severe Thunderstorm Watch 0192. Stronger effective bulk
    shear values are present in western Kansas, where occasional
    supercell structures have been observed. Deep-layer and low-level
    shear decrease with eastward extent, suggesting that storms will
    remain multicellular and outflow dominant in eastern portions of the
    watch and perhaps points east.

    CAPE of 500+ J/Kg in the -10 to -30 C layer suggests that large hail
    will remain a concern, while a relatively well-mixed boundary layer
    should promote strong evaporative cooling with an associated risk
    for isolated damaging wind gusts with the more intense storms.
