Sioux Falls, South Dakota – South Dakota is moving into a quieter but increasingly variable weather pattern late January into early February, with noticeable temperature swings expected statewide while precipitation chances remain low.
According to the National Weather Service Climate Prediction Center, the Jan. 24–Feb. 6 outlook places South Dakota in an equal-chance category for both temperature and precipitation. This points to a transition period, with a nearby cold front allowing alternating pushes of colder and milder air without the moisture needed to support snow or rain.
Eastern South Dakota, including Sioux Falls, Brookings, and Yankton, could see pronounced day-to-day changes, with cold mornings followed by milder afternoons before temperatures dip again. These swings may be driven by shifting winds as the cold front wobbles across the region.
Central South Dakota, including Pierre, may experience similar variability, while western South Dakota and the Black Hills could see sharper overnight cool-downs when colder air briefly settles south. Despite the temperature changes, skies are expected to remain mostly dry, limiting travel or infrastructure concerns.
The primary impacts will involve adjusting to fluctuating temperatures rather than storm-related hazards. Residents are encouraged to dress in layers, remain mindful of colder mornings and evenings, and monitor daily forecasts for rapid changes.
This pattern of temperature variability is expected to persist into early February. While conditions remain quiet for now, updated outlooks may be issued if the cold front shifts position or becomes more active.
