    Mesoscale Discussion 0035

    0253 PM CST Wed Jan 05 2022

    Areas affected...portions of far southeast Wyoming...far northeast Colorado...southwestern Nebraska...far northwest Kansas

    Concerning...Heavy snow=20

    Valid 052053Z - 060000Z

    SUMMARY...A couple hours of heavy snow are likely, with up to 1-2
    inch/hour rates possible with the heavier snow bands.

    DISCUSSION...MRMS mosaic radar data depicts two primary heavy snow
    bands in progress. The first band is situated across far southeast
    WY/northeast CO, with the second overspreading the CO/KS/NE border
    area. The mid-level impulse serving as the impetus for the heavy
    snow event is now traversing the CO/NE border and is expected to
    continue propagating southeast, away from sub-freezing low-level
    temperatures. As such, the heavier snow ongoing across far southeast
    WY into extreme northwest KS may only last for a few more hours, as
    also suggested by high-resolution guidance consensus. In the
    meantime though, focused 700 mb warm-air/moisture advection oriented
    roughly perpendicular to intense surface-700 mb frontogenesis should
    still support localized but strong deep-layer ascent across portions
    of the central High Plains, with 1-2 inch/hr snowfall rates likely
    in several locales.
