Sioux Falls, South Dakota – Snow is set to develop across eastern South Dakota late this morning and ramp up through the afternoon, creating increasingly hazardous travel conditions by the time many drivers head home this evening.
According to the National Weather Service in Sioux Falls, light snow will begin spreading into the region late this morning, with coverage and intensity increasing through midafternoon and into the early evening hours. The most impactful snowfall rates are expected from midafternoon through early evening, when visibility may drop and roads become slick during the peak of the evening commute.
Most locations across eastern South Dakota, southwest Minnesota, and northwest Iowa are expected to see general snowfall totals of 1 to 2 inches through tonight. However, forecasters note there is a better chance for isolated pockets of 2 to 4 inches, especially where heavier snow bands develop. Even modest accumulation could quickly lead to slippery conditions given cold pavement temperatures.
Travel impacts are most likely along major routes including I-29, I-90, and Highway 14, particularly during periods of heavier snowfall. Reduced visibility, snow-covered roads, and slower travel speeds are expected at times.
Drivers are urged to plan ahead, allow extra travel time, and check road conditions before heading out this afternoon and evening. Snow tapers off later tonight, but slick spots may linger into early Wednesday as temperatures remain cold. Additional updates will be issued if snowfall rates or impacts trend higher.
