    Areas affected...Central to northern Wyoming

    Concerning...Snow Squall=20

    Valid 150043Z - 150445Z

    SUMMARY...Rapidly falling temperatures, strong winds, and moderate
    snowfall behind a sharp cold front are yielding brief
    blizzard/snow-squall conditions across north-central Wyoming. These
    conditions may persist and spread into central and eastern Wyoming
    over the next few hours.

    DISCUSSION...Recent radar mosaics show a cold front rapidly pushing
    southward to the west of the Big Horn mountains in north-central WY.
    Surface observations behind the front have reported temperatures
    falling from the low 50s and upper 40s to below freezing within an
    hour. Concurrently, strong low-level cold advection (coupled with
    strong background gradient winds) is yielding frequent post-frontal
    wind gusts of 30-50 mph. This combination of rapidly falling
    temperatures, strong wind gusts, and the development of light to
    moderate snow showers within the frontal zone is yielding periods of
    visibility reductions between 1/2 to 1/4 mile based on regional
    ASOS/AWOS reports and web cams.=20

    The cold front is expected to continue pushing south/southeast over
    the next several hours as a cyclone continues to intensify to the
    east over the High Plains. Light to moderate snow showers will also
    spread to the southeast, which may result in a rapid onset of
    flash-freeze conditions and sudden visibility reductions under the
    heavier snow showers across central to east-central WY where
    temperatures are currently above freezing.
