Sioux Falls, South Dakota – A biting northwest wind is cutting across eastern South Dakota this morning, sweeping powdery snow over roads and parking lots as temperatures hover near 20 degrees. The air feels raw — that early November kind that warns winter is close. Drivers along I-29 and I-90 may find slick bridges and refreeze spots where yesterday’s melting snow turned to ice before dawn.
According to the National Weather Service in Sioux Falls, patchy blowing snow and light refreeze hazards will persist through the morning before calmer air settles in later today. Wind chills are dipping into the single digits, and by early Monday, a few areas west of the Big Sioux River could briefly touch zero. These conditions make travel slow on rural routes and overpasses, where drifting snow tends to linger.
Residents are urged to bundle up, give themselves extra driving time, and keep vehicles fueled in case of delays. Clearing skies this afternoon will allow temperatures to rebound slightly, but the chill will hold through Monday before milder air arrives.
By Veterans Day, highs will climb back near 50 under mostly sunny skies — a welcome break for parades and outdoor ceremonies. Late-week trends suggest steady warming, with mid-50s to near 60 by Thursday and Friday. However, forecasters are watching another northern system forming over Montana and the Dakotas late next weekend that could bring the next round of cold air — a possible Thanksgiving preview of deeper winter ahead.
