SIOUX FALLS, S.D. – Fall winds are kicking up across eastern South Dakota today as a weak disturbance brings gusty conditions, patchy fog, and a few scattered showers before sunshine and mild air take hold for the weekend. Visibility may briefly drop early north of I-90, and drivers are urged to use caution through midmorning.
According to the National Weather Service in Sioux Falls, a 30 percent chance of light rain lingers Thursday as south winds gust up to 35 mph. The system moves east by Friday morning, leaving behind clear skies and more comfortable conditions. Friday will be the week’s standout—bright, breezy, and warm with highs near 70°F.
Saturday keeps the mild trend going, with sunshine early and just a slight chance of a passing shower by afternoon. Winds ease and temperatures hover near 60°F, making it ideal for fall yardwork, pumpkin patch visits, or outdoor sports. Sunday looks even better—sunny, calm, and seasonably cool around 63°F.
Those traveling across southeastern South Dakota this weekend can expect dry pavement and great visibility on I-90 and U.S. 81.
