    Areas affected...portions of central and southern Vermont and New
    Hampshire to the South Coast of Maine.

    Concerning...Severe Thunderstorm Watch 397...

    Valid 262016Z - 262215Z

    The severe weather threat for Severe Thunderstorm Watch 397
    continues.

    SUMMARY...The threat for large hail up to 1.5" and locally severe
    wind gusts of 60-65 kt continues across the watch area.

    DISCUSSION...An earlier cluster of thunderstorms with embedded
    supercell structures that produced wind damage and some small hail
    in central Rutland County, VT has recently weakened. However, the
    lingering convection is in the vicinity of a diffuse warm front that
    extends southeast through southeastern NH. That boundary along with
    orographic ascent along favored terrain in the Green and White
    Mountains may aid in additional storm formation late this afternoon
    into early evening. Given the presence of 1000 J/kg MLCAPE and 35-45
    kt of effective bulk shear, the environment is expected to remain
    supportive of additional severe storms capable of hail up to 1.5"
    and damaging wind gusts for the next few hours.
