    Areas affected...Northern Vermont...Northern New
    Hampshire...portions of Western and Central Maine

    Concerning...Freezing rain=20

    Valid 250100Z - 250500Z

    SUMMARY...Freezing rain accumulations around 0.01-0.03 per per hour
    likely through the evening.

    DISCUSSION...Freezing rain accumulations of 0.01-0.03" have been
    reported across upstate New York over the last hour, with freezing
    rain being reported at several stations across portions of Vermont
    and New Hampshire. This threat will likely shift eastward into
    western Maine over the next few hours. The observed 00z sounding
    from GYX shows the profile is largely below zero from the surface to
    just above 850 mb. Strong warm air advection is ongoing in low to
    mid-level west to southwesterly flow from 850-500 mb. This is
    further supported in RAP forecast soundings indicating warming above
    the surface should support the downstream threat of freezing rain as
    the heavier precipitation arrives northeastward. Areas across the
    higher terrain of the White Mountains will likely see snow, with the
    best potential for freezing rain accumulations located across the
    lower valleys.
