    Mesoscale Discussion 0518

    Areas affected...Parts of lower MI...eastern/central IN...and
    western OH

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

    Valid 241822Z - 242045Z

    Probability of Watch Issuance...5 percent

    SUMMARY...A few strong storms capable of producing locally damaging
    wind gusts are possible through the afternoon.

    DISCUSSION...A broken band of thunderstorms is moving eastward
    across parts of central lower MI, where subtle midlevel height falls
    are occurring ahead of a midlevel trough approaching from the west.
    While poor midlevel lapse rates and modest boundary-layer moisture
    (middle 50s dewpoints) are limiting buoyancy ahead of these storms,
    around 35 kt of midlevel south-southwesterly flow preceding the
    trough and steepening low-level lapse rates could support a couple strong/loosely organized cells/clusters capable of locally damaging
    wind gusts. While large-scale forcing for ascent decreases with
    southward extent, a similar environment may support a couple strong
    storms with an attendant risk of locally damaging gusts across
    central/eastern IN into western OH as well.
