Drivers across eastern South Dakota and parts of northwest Iowa are urged to use caution this morning as light to moderate snowfall continues, with hazardous travel conditions expected before snow tapers off around midday.
According to the National Weather Service in Sioux Falls, snowfall will gradually end from the north and west later this morning, with the heaviest additional accumulation south of the Huron–Sioux Falls–Spencer, Iowa line. Forecasters expect an additional 1 to 2 inches of snow in those areas before precipitation comes to an end.
Cities including Sioux Falls, Yankton, Mitchell, Brookings, Storm Lake, Spencer, and Worthington may experience periods of reduced visibility, especially during the morning hours. Untreated roads, bridges, and ramps are expected to remain slick, particularly during early travel.
The NWS notes that while snowfall rates are not expected to be intense, steady accumulation combined with lingering cold temperatures will continue to impact driving conditions. Travel impacts are most likely through the late morning hours, with conditions improving as snow exits the region.
Motorists are advised to slow down, increase following distance, and allow extra travel time. Those traveling along major routes such as Interstate 29, I-90, and Highway 81 should remain alert for sudden changes in visibility.
Snow is expected to fully taper off by around noon Saturday, though spotty slick conditions may persist into the afternoon, especially in shaded and rural areas.
