Sioux Falls, SD — Mixed precipitation across parts of Iowa, Minnesota, and South Dakota could create slippery travel overnight into Saturday morning.
According to the National Weather Service in Sioux Falls, a Winter Weather Advisory remains in effect until 9 a.m. CST Saturday for portions of northwest Iowa, southwest Minnesota, and southeast South Dakota.
Forecasters say the system may produce up to 1 inch of snow and as much as 0.20 inches of ice, with freezing precipitation expected to develop Friday evening and continue overnight before tapering off Saturday morning.
Communities included in the advisory stretch across the tri-state region, including Sioux Falls, Yankton, Vermillion, Worthington, Spencer, Sheldon, Orange City, and Rock Rapids, along with dozens of surrounding towns.
The primary concern is ice accumulation, which can coat roadways, bridges, and untreated surfaces. Even small amounts of freezing rain can quickly lead to hazardous driving conditions, particularly during overnight and early morning hours when temperatures remain below freezing.
Transportation officials warn that untreated roads may become slick, especially on rural highways, bridges, and elevated road surfaces. Drivers are encouraged to slow down and allow extra stopping distance.
Road conditions in affected states can be checked by dialing 511, which provides real-time travel updates.
Overnight icing events like this can affect early-morning commuters and students heading to school Saturday activities if untreated roads remain slick.
Officials recommend allowing extra travel time and using caution if driving during the advisory period.
