    Areas affected...Southern New Hampshire and northern Massachusetts

    Concerning...Severe Thunderstorm Watch 549...

    Valid 162314Z - 170115Z

    The severe weather threat for Severe Thunderstorm Watch 549
    continues.

    SUMMARY...The severe wind threat across WW 549 will mostly remain
    focused across southern New Hampshire and northern Massachusetts for
    the next 2 hours before a line of storms moves off shore. Wind gusts
    upwards of 55 to 65 mph appear possible based on environmental
    conditions and recent observations.

    DISCUSSION...A well-organized MCS continues to push east across the
    New England region with a recent wind report of 66 mph noted in
    Berkshire county, MA within the last hour. Temperatures are falling
    into the low to mid 70s in the wake of the line, indicating that a
    deep cold pool remains in place and should help maintain MCS
    intensity for the near-term with wind gusts up to 55-65 mph
    possible. This assertion is supported by recent velocity imagery
    from KENX, which shows at least two focused corridors of stronger
    winds within the line. Immediately downstream of the MCS, a plume of
    relatively higher theta-e is noted in recent surface
    observations/analyses as low 70s dewpoints continue to advect
    northward. This local corridor of better buoyancy should also help
    maintain MCS intensity as it translates eastward towards the New
    England coast. Latest timing estimates suggest the gust front should
    reach the coast roughly around 01 UTC, though the severe wind threat
    may persist after 01 UTC for far southern Maine.
