    Mesoscale Discussion 1276

    Areas affected...Central/eastern New York and Pennsylvania

    Concerning...Severe Thunderstorm Watch 375...

    Valid 140112Z - 140245Z

    The severe weather threat for Severe Thunderstorm Watch 375
    continues.

    SUMMARY...An organized line of convection will be capable of
    strong/damaging wind gusts for another hour or two before
    encountering stable air within the Adirondacks and Delaware River
    Valley. No additional watches are expected this evening.

    DISCUSSION...A line of thunderstorms across central New York into
    central Pennsylvania has become somewhat more organized within the
    last 1-2 hours as cold pools have congealed. This has allowed
    portions of the line to surge out, which is most evident in
    north-central Pennsylvania. Occasional wind damage has been reported
    with one measured gust on the NY Mesonet of 78 mph at the Penn Yan
    site at 8:40 PM EDT. There is a narrow corridor of remaining buoyant
    airmass ahead of the line. Strong/damaging winds remain possible
    likely for another hour or two, particularly with any more
    pronounced bowing segments. Storms moving into the Adirondacks and
    Delaware River Valley will encounter much more stable surface
    conditions. Storms will quickly weaken as that occurs. No additional
    watches are expected this evening.
