    Areas affected...portions of central Vermont and New Hampshire into
    central Maine

    Concerning...Heavy snow=20

    Valid 232310Z - 240415Z

    SUMMARY...Heavy snow should continue across northern parts of New
    England into the evening hours. 1-2 inch/hr snowfall rates and
    periods of reduced visibility are possible, especially after 00Z (8
    PM EDT).

    DISCUSSION...Heavy snow is ongoing to the north of a strong
    low-level cyclone that is currently traversing the Atlantic
    Coastline. Regional dual-polarimetric radar data depicts the
    transition line between all snow and mixed wintry precipitation to
    be established from roughly the MA/VT border to central Penobscot
    County, ME, and the latest high-resolution model guidance suggests
    that this transition line should remain roughly stationary into the
    evening hours. 700 mb frontogenesis is increasing along the
    international border in tandem with increasing low-level WAA, and
    this should encourage increased snowfall rates as moisture and lift
    are boosted within the dendritic growth zone. 1-2 inch/hr snowfall
    rates are possible, especially later this evening (i.e. the 00-05Z
    time frame).
