    Areas affected...southern OH

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

    Valid 300623Z - 300800Z

    Probability of Watch Issuance...5 percent

    SUMMARY...A brief tornado and localized damaging wind threat may
    persist for a another hour or two with a cluster moving
    east-southeast across a portion of southern Ohio. Overall threat is
    expected to subside before dawn.

    DISCUSSION...A cluster intensified last hour over southwest OH with
    at least one TDS noted just southwest of the ILN radar into Clinton
    County. A surge in IR cloud top cooling occurred just before this
    TDS and has since warmed, but transient mesovortices remain possible
    along the leading edge of the gust front. While there is adequate
    low-level shear in the ILN VWP data, weaker flow with minimal change
    in direction has persisted above 1 km AGL, suggesting long-term
    organizational potential will be limited. Downstream buoyancy is
    increasingly meager with eastern extent (below 500 J/kg) as this
    cluster progresses east-southeast at around 35 kts. As such, the
    brief tornado/localized damaging wind threat will probably diminish
    after about 08Z.
