    Areas affected...New York City Vicinity into southern New England

    Concerning...Blizzard=20

    Valid 230545Z - 231045Z

    SUMMARY...Moderate to heavy snowfall will continue from the NYC
    Metro vicinity into southern New England. Snowfall rates of 1-2
    inches per hour are likely with localized 2+ inches per hour
    possible. Greater rates will spread north with time. Blizzard
    conditions will also become more prevalent, particularly near the
    coast.

    DISCUSSION...Over the past 5 hours, the surface cyclone off the
    Mid-Atlantic coast has deepened approximately 9 mb per objective
    analysis. Bands of moderate to heavy snow continue to pivot into the
    NYC metro vicinity as well as southern New England. Moderate snow
    observations are beginning to occur into Massachusetts. As the upper
    trough continues to intensify and become more negatively tilted, the
    surface cyclone will deepen further into Monday morning. A long
    duration of at least moderate snowfall can be expected. Closer to
    4-7 AM EST, a zone of very favorable ascent is expected to set up
    over southern New England. Snowfall rates of 1-2 inches per hour are
    likely along with the potential for localized 2+ inches per hour.
    Greater snowfall rates will also gradually shift northward as the
    system slowly lifts northeastward.

    Beyond significant snowfall rates, surface winds have already begun
    to increase from the Mid-Atlantic into southern New England. Current observations show winds gusting into the mid 30s to low 40s kts in
    Long Island. This trend should continue over the next several hours.
    Blizzard conditions will remain more likely near the coast, but
    inland areas will become increasingly impacted by strong winds and
    reduced visibility later this morning.
