Sioux Falls drivers may face reduced visibility early Sunday as patchy fog forms across parts of eastern South Dakota. Motorists along I-29, Highway 75, and rural routes near rivers and lakes should prepare for sudden low-visibility conditions, with travel delays possible.
According to the National Weather Service in Sioux Falls, fog could lower visibility to less than one mile in spots Sunday morning before skies clear. Conditions improve by midday, bringing sunshine and a comfortable high near 71. Winds remain light but could gust to 20 mph.
The fog risk stretches across southeast South Dakota into southwest Minnesota, northeast Nebraska, and northwest Iowa. Travelers leaving Sioux Falls before 10 a.m. Sunday should allow extra time and use headlights in fog-prone areas. Residents near the Big Sioux River may see the thickest patches of fog.
After Sunday’s morning slowdown, the week trends calm and clear. Highs remain steady in the low to mid-70s with mostly sunny skies. Nights will stay cool, with lows dipping into the mid-40s and 50s. Winds taper off by Monday, creating several quiet days for outdoor plans, farming activity, or late-August travel.
