    Mesoscale Discussion 0469

    Areas affected...portions of northern Pennsylvania into southwestern
    New York

    Concerning...Severe potential...Watch possible=20

    Valid 162057Z - 162200Z

    Probability of Watch Issuance...40 percent

    SUMMARY...A couple of damaging gusts are possible over the next
    couple of hours. However, the environment downstream of the ongoing
    storms does not appear particularly favorable for severe. Convective
    trends are being monitored for the need of a WW issuance.

    DISCUSSION...Semi-discrete convection has failed to materialize
    across NY up to this point, possibly due to a boundary layer that is
    too dry to support convective initiation. A line of low-topped
    thunderstorms along a surface trough has organized along the PA/OH
    border, and is quickly progressing east-northeast. A few damaging
    gust reports have been received within the past hour in northwest
    PA. However, the ongoing line of storms is approaching an even drier
    airmass, characterized by upper 40s to lower 50s F surface
    dewpoints. As such, confidence in sustenance of the ongoing storms
    is not overly high. Nonetheless, convective trends will continue to
    be monitored for the need of a WW issuance should the storms
    maintain their intensity.
