South Dakota – Cold rain taps windshields and visibility drops fast across Sioux Falls, where temperatures hover near 36°F and roads remain wet with conditions set to deteriorate within hours.
According to the National Weather Service in Sioux Falls, steady rainfall will continue through the day with totals between 0.50 and 0.75 inches, especially east of Interstate 29. Colder air moves in by Friday morning, bringing a transition to freezing rain and a wintry mix that could create icy stretches, particularly along I-90 .
Across Minnehaha County and into northwest Iowa, drivers should prepare for rapidly changing road conditions. Rain may briefly intensify before temperatures slip toward freezing. Bridges and overpasses will ice first. Plan extra time and reduce speed.
By Friday, precipitation becomes more complex. Freezing rain mixes with snow before shifting back to rain at times. A few thunderstorms may even develop in nearby areas, adding bursts of heavier precipitation and reduced visibility.
Looking into early Saturday, light snow accumulation remains possible north of Sioux Falls, though icing remains the bigger concern region-wide. Winds will pick up, adding a biting edge and making travel more difficult in open areas.
The first weekend of April improves gradually. Sunshine returns Sunday with highs climbing into the low 50s, offering a break from the messy pattern. A broader warming trend develops into next week, with temperatures moderating closer to seasonal levels.
