    Mesoscale Discussion 1034
    NWS Storm Prediction Center Norman OK
    0322 PM CDT Tue Jul 10 2018

    Areas affected...East-central New York...central New England

    Concerning...Severe potential...Watch unlikely

    Valid 102022Z - 102245Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated severe possible with scattered storms developing
    across the area. Marginally severe hail and wind gusts are the main
    threats. A WW issuance is not expected at this time.

    DISCUSSION...Scattered storms continue to develop well ahead of a
    cold front in a broadly confluent low-level airmass across a large
    portion of New England this afternoon, with additional storm
    development possible within the next few hours. Storms will likely
    persist through the rest of the afternoon in association with
    maximum diurnal heating and associated buoyancy (MLCAPE of around
    1000 J/kg).

    The ambient kinematic environment is characterized by deep layer
    unidirectional flow, with appreciable speed shear contributing to
    bulk effective shear values of 30-40 knots. A few of the stronger
    storms may become organized enough to pose a threat for isolated,
    marginally severe hail and wind gusts through the remainder of the
    diurnal heating cycle. The sparse nature of the severe threat
    suggests that a WW issuance is not warranted at this time.
