    Areas affected...portions of central and eastern NY

    Concerning...Severe Thunderstorm Watch 631...

    Valid 272022Z - 272215Z

    The severe weather threat for Severe Thunderstorm Watch 631
    continues.

    SUMMARY...Through 22-23Z, the greatest severe weather threat is
    expected to spread east from the eastern Finger Lakes and vicinity
    toward the Hudson Valley/Capital District. Damaging winds will
    remain the primary hazard, with marginally severe hail and a brief
    tornado or two also possible.

    DISCUSSION...Despite considerable cloudiness, which has slowed more
    robust air mass destabilization, broken bands of semi-discrete
    storms have evolved over portions of central NY, with the most
    intense storms extending from north of Binghamton to northeast of
    Utica as of 2015Z. That activity is occurring within a kinematic
    environment featuring 30-35 kt of deep-layer shear, per current KBGM
    VWP.

    Latest model guidance suggests that storms will continue to
    intensify over the next 1-3 hours while progressing toward the
    Hudson Valley/Capital District. However, visible satellite imagery
    shows the presence of wave-type clouds over the Catskills, which are
    indicative of some degree of stability. On the condition that
    sufficient instability exists, locally backed surface winds and
    resultant stronger low-level shear evident in the KENX VWP (compared
    to KBGM) may support an increased supercell risk late this
    afternoon. Damaging wind gusts will remain the predominant hazard,
    though marginally severe hail and a brief tornado or two are also
    possible.
