    Mesoscale Discussion 0126
    NWS Storm Prediction Center Norman OK
    0529 AM CST Mon Mar 02 2026

    Areas affected...Eastern Indiana...central and southern Ohio...and
    northern Kentucky.

    Concerning...Winter mixed precipitation=20

    Valid 021129Z - 021400Z

    SUMMARY...Moderate snow and light to moderate freezing rain/sleet
    will continue this morning.

    DISCUSSION...Moderate isentropic ascent ahead of a weak mid-level
    shortwave trough has resulted in a broad region of light to moderate precipitation within the Ohio Valley. On the northern extent of this precipitation shield, some frontogenetical banding (centered around
    700mb) has resulted in moderate snow across portions of eastern
    Indiana into central Ohio. South of this snow band, warmer
    temperatures aloft have resulted in a combination of sleet and
    freezing rain. The wet-bulb zero line is centered near I-64 this
    morning and will likely delineate the area to the south with mostly
    rain and the area to the north which could see some ice accretion
    (up to 0.05 inches per hour) for a few hours this morning.

    This combination of moderate snow across central Ohio and mixed
    precipitation across southeast Indiana, southern Ohio, and northern
    Kentucky will continue through mid morning, before temperatures warm
    above freezing and it changes to all rain across most of the region
    by late morning.
