South Dakota wakes to crisp, biting air this morning as a fresh pulse of arctic cold pushes across the Northern Plains, tightening its grip through Sunday. Light flakes may drift again at times, but the real concern today is the rapid cooling and increasingly slick pavement as melting snow refreezes across highways and neighborhood streets.
According to the National Weather Service, another round of accumulating snow is on track to build from the Northern Plains into the Upper Mississippi Valley through the weekend. Sioux Falls and surrounding counties could see 2 to 4 inches by Sunday as heavier bands redevelop along the advancing cold front. Drivers should plan for slushy-to-icy transitions during the afternoon and evening, especially on I-29 and rural east–west routes.
Winds strengthen today and Saturday, producing low visibility at times and stirring patchy blowing snow across open fields. Gusts near 30 mph will make the already-cold day feel far worse, with “feels-like” values dipping below zero. Meteorologists now track a sharper cold push for late Saturday into Sunday, raising the chance for a “winter tease” pattern—quick bursts of snow, rapid freeze-ups, and scattered slick spots before sunrise Sunday.
Residents heading out for early holiday errands should keep gloves, coats, and emergency blankets in their vehicles. Plan extra time for any Sunday morning travel as conditions may deteriorate quickly once the next snow band arrives.
