    Areas affected...Far Southwest OH...Central/Eastern KY

    Concerning...Severe potential...Watch likely=20

    Valid 270159Z - 270300Z

    Probability of Watch Issuance...80 percent

    SUMMARY...The threat for severe gust and QLCS circulations will
    likely continue into far southwest Ohio and central/eastern
    Kentucky, and a Tornado Watch will likely be needed across the
    region to address this potential.

    DISCUSSION...Well-organized convective line continues to move
    eastward across southwest IN, southern IL, and far southwest KY at
    around 50 to 55 kt. This storm motion takes the line to the edge of
    Tornado Watch 324 at 0330Z to 0400Z. The airmass over the region is
    only weakly buoyant right now, but increasing low to mid-level
    moisture ahead of the line should promote the development of modest
    buoyancy. This buoyancy will be aided by strong low-level shear.
    Recent 00Z BNA sounding sampled strong low-level flow veering with
    height, with 0-1 km storm-relative helicity over 330 m2/s2. Recent
    JKL VAD sampled this increasing low-level flow as well, with 0-1
    storm-relative helicity over 400 m2/s2.=20

    Given the favorable kinematics and organized character to the
    ongoing line, the expectation is that the threat for severe gusts
    and QLCS tornado circulations will continue into the region. A
    Tornado Watch will likely be needed across the region to address
    this potential.
