    Areas affected...parts of New England and eastern NY

    Concerning...Heavy snow=20

    Valid 090301Z - 090700Z

    SUMMARY...Multiple bands of heavy snow with rates of 1-2 inches per
    hour should persist into the early morning across eastern New York
    into parts of New England.

    DISCUSSION...Radar imagery and surface observations, along with
    recent reports, indicate multiple swaths of heavy snow are ongoing
    across parts of the Northeast. The most probable area for the
    highest rates should exist over southern New England, just to the east-northeast of the occluding transition zone between snow and
    sleet. OKX dual-pol radar has sampled enhanced KDP below the
    dendritic growth zone, indicative of heavy snow. 21Z SREF and 00Z
    HREF guidance support potential for 2 in/hr bursts across parts of
    CT/MA/RI, until enough warming near 700 mb occurs for sleet and/or
    mid-level drying advects into the dendritic growth layer during the
    early morning.=20

    Farther north, a more west/east-oriented deformation zone from Lake
    Ontario to the Capital District should pivot east during the next
    several hours. Snowfall rates in this band should more steadily hold
    around 1 in/hr as it spreads across southern parts of VT/NH/ME.
