    Areas affected...portions of central and eastern New York into
    southern Vermont

    Concerning...Heavy snow=20

    Valid 230413Z - 230915Z

    SUMMARY...Periods of heavy snow are likely over the next several
    hours. 1+ inch/hr snowfall rates and reduced visibility are possible
    in the heaviest snow bands.

    DISCUSSION...925-850 mb warm-air advection continues to transport
    moisture into a sub-freezing troposphere amid a gradually amplifying
    mid-level trough approaching from the west. A shield of widespread
    moderate snow is already overspreading much of central and southern
    NY, with a couple instances of heavy snow already reported via
    surface observations. Increasing magnitudes and coverage of heavier
    snowfall rates (i.e. 1+ inches/hr) are expected to continue through
    the night as the approaching mid-level trough further amplifies and
    low-level warm-air advection persists.
