    Areas affected...far southern Indiana into central Kentucky

    Concerning...Severe Thunderstorm Watch 580...

    Valid 311947Z - 312145Z

    The severe weather threat for Severe Thunderstorm Watch 580
    continues.

    SUMMARY...The damaging/severe wind threat should remain focused
    across southern Indiana into central Kentucky for the next few hours
    as a consolidated cold pool becomes established.

    DISCUSSION...A consolidating cold pool is becoming evident in recent
    KLVX velocity imagery roughly along the OH River. This may be the
    start of a somewhat more organized MCS that will pose a relatively
    focused wind threat to areas downstream - namely central KY. To the
    southeast of the developing MCS, a more broken,
    meridionally-oriented, line of disorganized convection is
    delineating the western edge of a residual cold pool from prior
    convection where temperatures remain in the 70s and stable billow
    clouds are noted in visible imagery. As such, the developing MCS
    will likely continue to propagate south/southeast where buoyancy
    remains very favorable for convective maintenance (MLCAPE values in
    the 2000-3000 J/kg range). Limited line-orthogonal deep-layer wind
    shear may be a modulating factor to overall convective intensity
    given west/northwest deep-layer wind shear vectors, but the
    high-CAPE environment and surging cold pool should continue to
    support a damaging/severe wind threat for the next few hours.
