    Mesoscale Discussion 1295
    NWS Storm Prediction Center Norman OK
    0204 PM CDT Wed Aug 15 2018

    Areas affected...Northern NY...Northern VT

    Concerning...Severe potential...Watch unlikely

    Valid 151904Z - 152130Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Thunderstorms will remain possible for the next several
    hours. A few of these storms may produce isolated damaging wind
    gusts and/or hail.

    DISCUSSION...Strong heating amidst the moist airmass across the
    region is contributing to moderate instability ahead of a shortwave
    trough and associated cold front. Continued forcing for ascent along
    the boundary and attendant to the shortwave trough will provide the
    impetus for additional thunderstorms, although overall coverage is
    not expected to be particularly widespread. At the same time,
    enhanced mid-level flow attendant to the shortwave trough will
    spread eastward into the region, resulting in an increase in
    vertical shear. This increase in vertical shear supports the
    potential for more organized updrafts and a resultant threat for
    damaging wind gusts and/or hail. Limited severe coverage is expected
    to temper the need for a watch.
