    Areas affected...Portions of western New York

    Concerning...Severe potential...Watch unlikely

    Valid 091915Z - 092115Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Strong to marginally severe wind gusts are possible along
    and near the southern Lake Ontario shoreline. A watch is not
    expected given the limited spatial extent of the threat.

    DISCUSSION...A organized linear segment is ongoing near Toronto
    driven by ascent from a shortwave trough. While the airmass near the
    Lake Ontario shore is slightly cooler than surrounding areas, the
    organization of the linear segment will likely allow it to propagate
    some distance along the shoreline with aid from the lake breeze
    boundary. The spatial extent of the threat is not expected to reach
    farther inland than a county or two. Strong to marginally severe
    wind gusts, particularly along the more exposed lake shore, are
    possible.
