    Areas affected...the Northeast

    Concerning...Severe potential...Severe Thunderstorm Watch likely=20

    Valid 031657Z - 031900Z

    Probability of Watch Issuance...80 percent

    SUMMARY...Isolated to scattered damaging winds and isolated severe
    hail will be possible as initially isolated storms increase across
    parts of the Northeast. A Severe Thunderstorm Watch issuance is
    likely.

    DISCUSSION...Initial sustained storm development is underway across
    southwest NY, with scattered agitated CU over northeast PA and
    southeast NY. A plume of moderate buoyancy will expand eastward from western/central PA and southwest NY, aiding in strengthening
    convective intensity as storms mature. A strong mid-level westerly
    jetlet atop already veered and weak low-level winds will yield
    hodograph elongation. Combined with weak low-level ascent, the setup
    should support generally semi-discrete cells with transient
    mid-level updraft rotation. As such, isolated severe hail will be
    possible and the overall coverage of the convective wind threat
    might be subdued until late-afternoon clustering becomes more
    probable.
