    Areas affected...South-central Nebraska into far north-central
    Kansas

    Concerning...Severe Thunderstorm Watch 529...

    Valid 200005Z - 200130Z

    The severe weather threat for Severe Thunderstorm Watch 529
    continues.

    SUMMARY...A narrow window for a locally greater tornado threat will
    exist with supercells in south-central Nebraska. An additional risk
    of severe/damaging winds is also possible as this activity grows
    upscale.

    DISCUSSION...Two supercells continue to move southeastward into
    south-central Nebraska early this evening. With low-level hodographs
    from KUEX showing an increase in low-level SRH over the last hour,
    these storms will have some potential to produce a tornado. However,
    that window of opportunity may be relative confined in time given
    the ongoing signs of upscale growth on local radar. When this
    occurs, a greater threat for severe/damaging wind gusts would exist.
    Large hail remains possible, but MRMS MESH estimates have come down
    as storm interaction has steadily increased.
