    Mesoscale Discussion 0153
    NWS Storm Prediction Center Norman OK
    0441 PM CST Sun Mar 03 2019

    Areas affected...Northern Maryland and Delaware northeastward into
    southeast New York...and southern Connecticut

    Concerning...Heavy snow

    Valid 032241Z - 040245Z

    SUMMARY...Moderate snow is falling across much of northern Maryland
    and Delaware, southeast Pennsylvania, and New Jersey at this time.
    Snowfall rates are expected to increase through the evening with
    snowfall rates in excess of 2 inches per hour in the New York City
    metro area later this evening as the heaviest snow shifts
    northeastward.

    DISCUSSION...A 1005mb surface low is analyzed in northeast Georgia
    at 22Z with an expanding precipitation field to its north. Light to
    moderate snow is currently falling across northern Maryland and
    Delaware, southeast Pennsylvania, and New Jersey. Precipitation
    rates are expected to increase this evening as the surface low
    continues to deepen and moves off the North Carolina coast by 04 to
    05Z. The rain/snow line is expected to move slightly southeast over
    the next hour as precipitation rates increase (especially over New
    Jersey), but then move slightly northwest through the evening.
    However, overall the rain/snow line is expected to stay within 25
    miles of its current location. The heaviest snowfall is expected
    just northwest of this rain/snow line later this evening. This will
    most likely be near the New York City metro area between 03Z and 06Z
    where snowfall rates could exceed 2 inches per hour in some
    locations.
