    Mesoscale Discussion 0755
    NWS Storm Prediction Center Norman OK

    Areas affected...Portions of Ohio

    Concerning...Severe potential...Watch unlikely

    Valid 162052Z - 162145Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Isolated damaging gusts will remain possible into this
    evening. Watch issuance is not expected though.

    DISCUSSION...A few strong/severe storms have developed along a
    theta-e ridge near weak surface confluence over Ohio this afternoon.
    KILN VWP data sampled relatively weak/disorganized tropospheric flow
    and storm cell evolution in western Ohio seems largely driven by
    propagation along radially expanding outflow. Farther east, modestly
    stronger 700mb flow (noted in KPBZ VWP data) is yielding slightly
    more organization. In both cases, locally damaging winds will be the
    primary threat, aided by warm/moist boundary layer conditions. This
    threat will diminish this evening, as cells drift into weakening
    instability with southward extent.
