    Areas affected...portions of the Northeast

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

    Valid 142020Z - 142215Z

    Probability of Watch Issuance...20 percent

    SUMMARY...A few stronger storms may produce strong to severe gusts
    and marginal hail this afternoon.

    DISCUSSION...Widely scattered shower and thunderstorm activity is
    ongoing across portions of the Northern Adirondacks in New York to
    Kennebec Valley in Maine. Through much of the morning and early
    afternoon, this area has been under mid-level cloud cover which has
    reduced daytime heating. As a result of this and ongoing showery
    activity, very marginal instability is in place. This is observed
    from the 18z ALB and GYX soundings. Though instability remains weak,
    deep layer shear around 40-45 kts may support a few stronger
    updrafts capable of strong to severe wind and marginally severe
    hail. Given the spatially limited nature of this risk, a watch is
    unlikely at this time.
