    Mesoscale Discussion 1976
    NWS Storm Prediction Center Norman OK
    0910 AM CST Fri Dec 10 2021

    Areas affected...Far North-Central NE...South-Central into Southeast/East-Central SD

    Concerning...Heavy snow=20

    Valid 101510Z - 101915Z

    SUMMARY...Increasing snowfall rates are expected from north-central
    NE into east-central SD over the next few hours.

    DISCUSSION...Regional radar imagery currently depicts a band of
    moderate snow from north-central NE/south-central SD northeastward
    into portions of east-central SD. This snow band is expected to
    become a bit more organized over the next few hours as both the
    surface low (over the central High Plains) and associated
    low/mid-level low move northeastward. At the same time, warm-air
    advection throughout the northeastward periphery of the surface low
    will strengthen, with the associated ascent contributing to
    increased snowfall rates. Predominantly moderate snowfall is
    anticipated over the next few hours, with rates occasionally
    exceeding 1" per hour.
