Sioux Falls, South Dakota — Wind chills dropping well below zero overnight could create hazardous conditions for Monday morning travel.
According to the National Weather Service in Sioux Falls, snow and wind are expected to gradually diminish Sunday evening, but colder temperatures will move into the region overnight.
Forecast wind chill values across southeastern South Dakota, including Sioux Falls and surrounding communities, are expected to fall into the negative teens to near -20 degrees by early Monday morning. Areas farther west and north in the forecast region could experience similar or slightly colder apparent temperatures.
The cold arrives after periods of snow and gusty winds that affected the region earlier Sunday. As precipitation ends, lingering snow and reduced visibility may still leave some roads slick or snow-covered, particularly before sunrise Monday.
Forecasters advised residents to dress in warm layers and plan for potentially slower travel during the morning commute.
Cold wind chills can increase the risk of frostbite during prolonged outdoor exposure, especially in windy conditions. Officials recommend covering exposed skin and limiting time outdoors during the coldest overnight hours.
The advisory also serves as a reminder for drivers to check road conditions and allow extra time for travel Monday morning.
The conditions may be especially relevant for students and early-shift workers heading out before sunrise, when wind chills are expected to be at their lowest.
Additional updates and local forecasts are available through the National Weather Service Sioux Falls office, which continues to monitor conditions across the region.
