    Concerning...Winter mixed precipitation=20

    Valid 241453Z - 242000Z

    SUMMARY...Moderate to heavy freezing rain and sleet are expected to
    persist across the Ark-La-Tex to Ark-La-Miss regions into early
    afternoon. Liquid-equivalent precipitation rates of a tenth to
    quarter-inch per hour should be common, locally up to a half-inch
    per hour.

    DISCUSSION...A swath of moderate to heavy mixed precipitation is
    ongoing across east TX and the Ark-La-Tex. Surface observations
    confirm hourly precipitation rates of .10-.25 in/hr are common, up
    to around .50 in/hr. 12Z guidance is rather consistent in indicating
    this swath of precip persisting through at least early afternoon,
    gradually shifting east-northeast amid rather pronounced low-level
    warm theta-e advection. A classic freezing rain to sleet sounding
    was sampled at 12Z in SHV. This type of thermodynamic profile should
    continue to steadily push southward in northern LA. Farther east,
    the surface freezing line should only drift to nearly stall across
    western MS into the early afternoon.
