Sioux Falls, South Dakota – A milder late-winter pattern is setting up across South Dakota and Nebraska in the Feb. 21–27 window, increasing the likelihood of above-normal temperatures and shifting precipitation toward rain or a rain-sleet mix.
According to the National Weather Service Climate Prediction Center, both states fall within a 33% to 50% probability zone for above-normal temperatures during the 8- to 14-day outlook. That points to afternoon highs running several degrees above late-February averages, especially across southeastern South Dakota and eastern Nebraska.
While the warmer trend reduces the risk for widespread heavy snow, passing systems could still bring mixed precipitation. In central and western South Dakota, including Rapid City and Pierre, colder air may linger long enough to support brief periods of sleet or light snow, particularly overnight. Across eastern Nebraska, including Omaha and Lincoln, rain appears more likely during daylight hours, with sleet possible if surface temperatures dip near freezing before sunrise.
Drivers should stay alert for slick bridges and untreated rural highways, including stretches of I-29, I-90 and I-80, where brief refreezing can occur after sunset.
The broader setup favors active weather rather than a prolonged dry stretch. Additional updates from the National Weather Service may refine precipitation type and timing as late February approaches.
