    Areas affected...parts of the Northeast and southern New England

    Concerning...Severe potential...Watch possible=20

    Valid 011628Z - 011830Z

    Probability of Watch Issuance...40 percent

    SUMMARY...An isolated damaging wind threat from strong gusts is
    anticipated this afternoon across parts of the Northeast into
    southern New England. Severe Thunderstorm Watch issuance is possible
    if a more concentrated corridor of damaging winds becomes apparent.

    DISCUSSION...To the north of the favored region for scattered
    damaging winds across southern PA/NJ this afternoon, a more isolated
    and lower intensity threat is anticipated. With somewhat cooler
    surface temperatures, outside of the Lower Hudson Valley, amid
    similarly weak mid-level lapse rates, MLCAPE is expected to be more
    muted. But moderate to strong mid/upper-level speed shear will favor
    potential for semi-discrete convection and transient mid-level
    rotation, capable of small hail and generally isolated damaging
    winds. Bulk of morning guidance suggests a combination of lesser
    storm coverage and instability should modulate the overall wind
    threat. It is possible though that an uptick in convective intensity
    might occur if a cluster can approach the Lower Hudson Valley to
    southwest New England vicinity later this afternoon.
