    Mesoscale Discussion 1272

    Areas affected...eastern Illinois into western Ohio

    Concerning...Severe potential...Watch unlikely

    Valid 102148Z - 102345Z

    Probability of Watch Issuance...5 percent

    SUMMARY...A few storms may be capable of marginally severe wind
    gusts through early evening.

    DISCUSSION...Storms have gradually developed along a weak cold front
    across east-central Illinois, and over northern Indiana where a
    surface low was noted at 21Z. Farther east, an outflow boundary was
    analyzed from northeastern Indiana into central Ohio. Ahead of these boundaries, moderate instability has developed with MLCAPE of
    2500-3000 J/kg. As storms have only recently developed over Illinois
    and Indiana coincident with peak heating, they are expected to
    persist or increase a bit in coverage through early evening. Weak
    wind profiles should generally preclude much organization, but small
    clusters of storms may yield strong outflow winds.
