    Areas affected...Northeast KS

    Concerning...Severe Thunderstorm Watch 213...

    Valid 270717Z - 270815Z

    The severe weather threat for Severe Thunderstorm Watch 213

    SUMMARY...Strong wind gusts appear likely across northeast KS over
    the next two hours.

    DISCUSSION...Convective evolution over the past half hour suggests
    the cluster across north-central KS has transitioned to an
    organized, forward-propagating convective line. Storm motion within
    the northern portion of this line (now entering Washington and Clay
    counties) has increased to around 40 kt. A 56 kt gust was measured
    at Concordia KS as this portion of the line moved through. Air mass
    due east of this line is currently modestly unstable, but a corridor
    of upper 60s dewpoints continues to advect northward. Dewpoint at
    TOP and LWC recently increased to 68 and 70 deg F, respectively.
    This increasing low-level moisture will likely only result in a
    minimum increase in overall buoyancy, but should result in a
    lessening of the convective inhibition. These thermodynamic
    conditions, coupled with moderate westerly flow aloft and the
    persist strong, moist inflow, are expected to support storm
    maintenance. Organized character of the line suggests the threat for
    strong wind gusts will continue. Some hail may also occur,
    particularly if any storm mergers occur.
