    Concerning...Severe Thunderstorm Watch 218...

    Valid 031932Z - 032100Z

    The severe weather threat for Severe Thunderstorm Watch 218
    continues.

    SUMMARY...A strong to isolated severe threat, mainly in the form of
    damaging winds, should persist for a few more hours. These threats
    will diminish by early evening.

    DISCUSSION...Earlier discrete to semi-discrete cells have largely
    congealed into an emerging linear cluster from western CT into far
    southern NH. The linear segment will offer the best potential for
    damaging winds over the next couple hours across northern CT and MA,
    where surface temperatures in the low to mid 80s are prevalent.
    Marine-layer influence from Long Island Sound will curtail the
    southern extent of the severe potential, as well as earlier
    convection/marine influence near the coastal NH/ME portion of the
    watch. This suggests the severe-storm threat will diminish in the
    early evening.
