Sioux Falls, South Dakota – South Dakota residents can expect a mix of wind, light rain, and early fall warmth this weekend before clearer skies return by Columbus Day. The changing weather will bring breezy conditions and scattered showers, especially for travelers along Interstate 29 and U.S. Highway 18, where gusts could reach up to 35 mph.
According to the National Weather Service in Sioux Falls, a 40% chance of showers develops Saturday night, with the potential for isolated thunderstorms by Sunday afternoon. Winds will pick up from the south at 15 to 25 mph, gusting as high as 30 mph, creating travel challenges for high-profile vehicles and outdoor events. Drivers heading to pumpkin patches or leaf-viewing spots should secure decorations and plan for slippery roads during heavier showers.
By Monday, cooler air slides in behind the system, but conditions turn dry and sunny — ideal for Columbus Day events and outdoor cleanup. Temperatures will rebound to near 60 degrees by Tuesday, marking a pleasant mid-October pattern for most of eastern South Dakota.
Residents are encouraged to stay weather-aware through Sunday afternoon, as additional wind advisories could be issued if gusts strengthen.
