    Mesoscale Discussion 1076
    NWS Storm Prediction Center Norman OK
    0356 PM CDT Wed Jul 18 2018

    Areas affected...Southeast Kansas...southwest Missouri

    Concerning...Severe potential...Watch unlikely

    Valid 182056Z - 182300Z

    Probability of Watch Issuance...5 percent

    SUMMARY...A few isolated cases of severe wind gusts and hail are
    possible for the next hour or two. A WW is unlikely.

    DISCUSSION...A subtle, weak mid-level wave associated with an MCV is
    moving over an environment with 2000-2500 J/kg MLCAPE. Brief
    instances of a few convective downbursts is the most likely hazard
    with this activity. Isolated hail is also possible with 25-30 kts of
    effective bulk shear, however weak mid-level lapse rates should
    limit hail potential. As storms move slowly to the southeast,
    buoyancy drops off dramatically as earlier convective activity and
    associated cloud debris has limited insolation. A WW is unlikely.
