Some freezing rain and sleet occurred over Nuckolls and Thayer counties on this Thanksgiving Day. A large swath of precipitation developed from the Texas Panhandle northeast into Iowa, shortly after daybreak. This precipitation expanded and progressively filled during the morning hours. A mixture of light wintry precipitation developed over south central Nebraska. The precipitation was steadiest between 8 am and 12 pm CST. Thereafter, the freezing rain and sleet came through periodically, ending by 9 pm CST. This resulted in a minor glaze of ice. Roads became ice covered and treacherous for drivers.
A cold front had crossed south central Nebraska the day before, allowing an unseasonably cold Canadian air mass to seep southward into the region. Arctic high pressure was 1041 mb over Montana. In the upper-levels, a positively tilted trough extended from Hudson Bay southwest into the western United States, with a low over Utah and Nevada. Southwest flow extended from the Desert Southwest all the way into eastern Canada. A ridge was over the Gulf of Mexico.
