    Areas affected...Louisiana into Mississippi and northern Alabama

    Concerning...Winter mixed precipitation=20

    Valid 151717Z - 152115Z

    SUMMARY...A wintry mix of snow, sleet, and freezing rain is expected
    to spread east from southeast Arkansas and northern Louisiana into
    Mississippi and northern Alabama through early afternoon.

    DISCUSSION...Surface observations, LSRs, and MPING reports over the
    past 1-2 hours continue to show a mix of snow, sleet, and freezing
    rain from the ArkLaTex region into northern MS/AL within a broad
    precipitation swath. Isentropic ascent over a 925-850 mb frontal
    zone is forecast to persist through early afternoon as a
    low-amplitude wave, currently over the southern Plains, migrates
    east. Recent sleet LSRs and forecast soundings suggest that a mix of
    snow and sleet will be more likely where surface temperatures are in
    the low 20s or lower. Areas where temperatures are in the mid-20s or
    higher should have too shallow/warm of a sub-freezing layer to
    support much re-freezing of hydrometeors, making a sleet/freezing
    rain mix more probable. Forecast guidance suggests that
    precipitation intensity may gradually wane heading into the
    mid-afternoon hours, but a zone of impactful wintry precipitation
    appears probable prior to this occurring.
