SIOUX FALLS, S.D. – Fall winds sweep across eastern South Dakota this Saturday, setting up a mix of showers, breezes, and big weekend temperature swings ahead of a sunny Columbus Day. Travelers along I-29 and I-90 should prepare for gusty crosswinds and scattered rain through late Sunday before calmer skies move in.
According to the National Weather Service in Sioux Falls, a 40–50% chance of showers will persist through Sunday morning, with winds gusting as high as 35 mph from the south and southwest. Highs near 69°F Saturday will rise into the lower 80s Sunday before cooler, drier air settles in by the holiday. Drivers and outdoor planners should secure decorations, delay leaf-viewing drives until Monday, and use caution on bridges and open highways where strong gusts may affect high-profile vehicles.
By Columbus Day, sunshine dominates the region with light northwest winds and highs near 63°F—ideal for pumpkin patch visits and local fall festivals. The mild stretch continues into midweek with partly sunny skies and highs climbing back toward the 70s by Thursday. Cooler mornings may bring patchy fog in low-lying areas, but no frost or freeze concerns are expected at this time.
Residents should stay alert for changing wind conditions and minor travel delays through Sunday evening, then enjoy calm, sunny weather for the holiday ahead.
