    Areas affected...Southern Nebraska...northern KS

    Concerning...Severe Thunderstorm Watch 541...

    Valid 222253Z - 230030Z

    The severe weather threat for Severe Thunderstorm Watch 541
    continues.

    SUMMARY...Scattered severe thunderstorms will continue across the
    watch area with a risk for damaging gusts and large/isolated very
    large hail.

    DISCUSSION...Severe thunderstorms, which earlier initiated in the
    vicinity of a northeast-southwest surface trough, continue moving south/southeast across southern NE/northern KS at 2250z. These
    storms have a history of large/isolated very large hail up to 2.50
    inches in diameter and damaging gusts. In the short term, storms
    are expected to continue to pose a severe threat within a moderately
    unstable air mass and 35-40 kts of northwesterly shear. This should
    support a continuation of supercell storm structures through early
    evening posing a risk for damaging gusts and large/isolated very
    large hail.

    Farther southwest across western KS/eastern CO, severe thunderstorm
    coverage remains rather isolated, but a continued severe risk is
    expected for a few more hours as instability/shear profiles remain
    similar to farther east.
