    Areas affected...Portions of Northwest/north-central Kansas

    Concerning...Severe Thunderstorm Watch 200...

    Valid 242339Z - 250015Z

    The severe weather threat for Severe Thunderstorm Watch 200
    continues.

    SUMMARY...The potential for a tornado will continue from along the Sheridan/Decatur County line into the Norton/Graham County line.
    Downstream backing winds and temperature/dewpoint increases are
    supportive.

    DISCUSSION...A tornado has been confirmed near Selden, KS with a
    supercell that has had relatively persistent 50-60 kt rotational
    velocity on KGLD 0.5 degree velocity. The environment ahead of the
    storm is expected to continue to support tornadic potential as winds
    at Hill City and Norton have backed to east-southeast and
    strengthened. Temperatures and dewpoints have also risen slightly. A complicating factor could be developing convection in the inflow
    region of the storm, now evident in Graham County. This could
    potentially reduce tornado potential quicker than expected.
