    Areas affected...Lower Ohio Valley

    Concerning...Severe potential...Watch possible

    Valid 091742Z - 091945Z

    Probability of Watch Issuance...40 percent

    SUMMARY...A risk for damaging winds will evolve from eastward moving
    outflow in the lower Ohio Valley. The coverage of strong/severe
    storms is not clear, but a watch is possible this afternoon. Trends
    will be monitored.

    DISCUSSION...Outflow from convection associated with an MCV
    northwest of St. Louis is moving eastward into the lower Ohio
    Valley. As this boundary moves into an increasingly unstable airmass
    with strong heating and mid/upper 70s F dewpoints, some
    intensification is possible. The main risk for damaging winds will
    likely occur south of the cirrus plume from the MCV. With the MCV
    displaced to the northwest, shear/forcing enhancement will be
    minimal. The degree of damaging wind threat will be tied to how
    organized convection along the outflow boundary becomes. A watch is
    possible if convective trends warrant.
