    Areas affected...Maine...Northern Vermont and New Hampshire and far
    northeast New York

    Concerning...Severe Thunderstorm Watch 360...

    Valid 292216Z - 292345Z

    The severe weather threat for Severe Thunderstorm Watch 360
    continues.

    SUMMARY...An isolated damaging wind threat continues across severe
    thunderstorm watch 360. The greatest threat for severe storms will
    be in Maine.

    DISCUSSION...Storms have have formed ahead of a cold front in Maine,
    Vermont and New Hampshire. The strongest storms have been in Maine
    thus far where mid-level temperatures are slightly cooler and
    effective shear is stronger. Further south, a warmer nose between
    700 and 500 mb has limited mid-level lapse rates to around 5 to 5.5
    C/km. This is likely why storms in this area have struggled more
    than the storms further north. Expect the corridor of greatest risk
    to remain in Maine due to the aforementioned reasons, but cannot
    rule out occasional stronger storms further south along the line.

    In addition, the warm front has now lifted north of the deeper
    convection, and boundary layer flow has veered somewhat. Therefore,
    while an isolated tornado cannot be ruled out given around 30 knots
    of flow around 1 km, the overall tornado threat has lowered.
