Sioux Falls, South Dakota – Light snow and pockets of freezing drizzle are expected to impact the Tri-State region beginning Saturday afternoon and continuing into Sunday morning, with travel impacts possible along Interstate 29 and surrounding roadways, according to the National Weather Service in Sioux Falls.
Snow is forecast to move from west to east across eastern South Dakota, southwest Minnesota, and northwest Iowa. Most areas can expect a dusting to around one inch of snow, though isolated pockets may receive up to two inches, especially west of I-29. While snowfall amounts will generally be light, even small accumulations may lead to slick roads and reduced visibility, particularly during peak travel periods.
In addition to snow, light freezing drizzle is possible Saturday evening as temperatures hover near freezing. This may result in a light glaze of ice—up to two-hundredths of an inch—mainly west of I-29, increasing the risk for slippery roadways, sidewalks, and bridges. Areas with higher elevations in east-central South Dakota and southwest Minnesota may see brief icing during the evening hours.
Southerly winds will increase Saturday afternoon, with gusts between 25 and 30 mph, leading to blowing and drifting snow in open areas and brief reductions in visibility. Winds may gust higher at times, further complicating travel conditions along I-29, I-90, and nearby highways.
Peak impacts from snowfall are expected Saturday afternoon through late evening, while ice-related concerns peak Saturday evening into early overnight hours. Conditions are expected to gradually improve by Sunday morning as precipitation tapers off.
Motorists are urged to monitor road conditions before traveling, allow extra time, and adjust plans if necessary. Forecast details may change as the system evolves, and travelers should stay updated through the National Weather Service and local transportation agencies.
