The Great Plains region is expected to experience between 0 and 25 fewer days per year with a minimum temperature below 10 degrees Fahrenheit by the middle of the century.

The largest decreases are expected in the northern half of the region. The smallest decrease in cold days is expected in Oklahoma and Texas, where these kinds of cold days rarely occur. Similarly, the region is expected to have up to 32 fewer days with a minimum temperature below 32 degrees by the middle of the century, particularly in western Montana, Wyoming, and the western edges of Nebraska, Kansas, Oklahoma, and Texas.
