    Areas affected...parts of the Northeast and southern New England

    Concerning...Heavy snow=20

    Valid 082321Z - 090315Z

    SUMMARY...Leading corridor of winter storm across the Northeast will
    produce a heavy snow band before transitioning to sleet/freezing
    rain from the southwest. Heavy snowfall rates of 1-2 inches per hour
    are likely.

    DISCUSSION...A fast-moving swath of winter mixed precip will spread
    across the Northeast and southern New England states through the
    rest of this evening. Strengthening low to mid-level ascent will
    yield a band of heavy snow along the leading periphery of this
    precip plume where the thermodynamic profile remains entirely below
    freezing. The initial swath should emanate out of the north-central PA/southwest NY vicinity, where heavy snow has been observed, and
    should expand east-southeastward along the NY to PA/NJ border area
    over the next few hours. A longer-lasting deformation zone within
    the cold-conveyor region should develop east from the Lake Erie
    vicinity and move across much of southern NY during the next several
    hours. A highly consistent signal persists across daytime guidance
    with snowfall rates of 1-2 in/hr. The southern portion of the heavy
    snow swath to about the Upper DE and Lower Hudson Valleys should mix with/transition to sleet/freezing rain later in the evening.
