    Mesoscale Discussion 1509
    NWS Storm Prediction Center Norman OK
    1020 PM CDT Thu Aug 12 2021

    Areas affected...Northeast KS...Northwest MO...Southeast NE

    Concerning...Severe potential...Watch unlikely=20

    Valid 130320Z - 130545Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Sporadic intense thunderstorm development may continue
    overnight, with a threat of isolated severe hail and wind.

    DISCUSSION...Periodic intense thunderstorm development has been
    noted for much of the evening across northeast KS and northwest MO,
    with a few reports of severe hail since 00Z. This activity is being
    supported by strong elevated buoyancy, as observed in the 00Z TOP
    sounding. While generally weak vertical shear will continue to limit
    storm organization, a modest low-level warm advection regime will
    continue to support occasional strong thunderstorm development
    overnight, with the strongest cells capable of hail and isolated
    strong wind gusts.
