    Mesoscale Discussion 0115
    NWS Storm Prediction Center Norman OK
    1233 PM CST Tue Feb 18 2025

    Areas affected...East-central Oklahoma into central Arkansas

    Concerning...Winter mixed precipitation=20

    Valid 181833Z - 182230Z

    SUMMARY...Freezing rain and sleet are possible from east-central
    Oklahoma into portions of central Arkansas. Deeper cold air will
    push into the region by this evening and a transition to primarily
    snow is expected at that time.

    DISCUSSION...A band of precipitation driven by warm advection
    continues to increase along and near a low-level boundary. The 18Z
    observed LZK sounding showed a small increase in the strength of the
    warm nose near 800 mb as compared to the observed 12Z sounding. Some
    low-level dry air remains, but this should saturate with time. Given
    the depth of the cold air, some mix of sleet and freezing rain
    appear possible. Sleet will be more likely with any more convective
    elements as steeper mid-level lapse rates were noted on the observed
    soundings. Into southeast Oklahoma into southern Arkansas,
    temperatures are above freezing currently. Some locations could see temperatures at or below freezing as precipitation starts and
    diabatically cools the profile. By evening, colder air should push
    into the region and a transition to primarily snow will likely
    occur.
