South Dakota – Crisp air stings cheeks this morning as Sioux Falls wakes up under clear skies and a biting 24-degree chill. The calm start will not last. Weather conditions shift quickly later today as moisture approaches and winter reminders stack up heading into the weekend.
According to the National Weather Service in Sioux Falls, clouds thicken today with a chance of rain developing late morning, then a switch to snow by late afternoon. Highs reach near 41, but gusty north winds may reach 30 mph, making it feel colder. Wet pavement could turn slushy as temperatures slide late.
Snow chances linger into this evening, though accumulation looks limited for now. Even light snow can reduce visibility and coat roads, especially along I-29 and I-90. Drivers should slow down and watch for slick patches near sunset as temperatures dip toward the mid-20s.
Friday brings a brief break with partial sunshine and highs near 38. The calmer stretch ends quickly. By Saturday, colder air deepens across eastern South Dakota. A slight chance of snow returns early, followed by sunshine but sharp cold. Highs stall near 27, while winds keep it feeling harsher.
Saturday night turns bitter. Lows fall near 10 degrees, setting up a flash-freeze risk where daytime snowmelt refreezes. Side streets, parking lots, and untreated roads may turn icy before sunrise. Bundle up and allow extra travel time.
Sunday stays mostly sunny but cold, with highs near 33. Moderation arrives early next week as highs rebound into the upper 40s, though winter remains firmly in control.
By the end of January, Sioux Falls gains about 40 extra minutes of daylight, a small win during a long winter stretch. Traveling this weekend? Tell us what road conditions look like where you are.
