Sioux Falls, SD – Pockets of heavy rain and low visibility are impacting Sunday travel across South Dakota as rounds of showers and thunderstorms continue through the morning and into tonight. Lingering smoke and poor air quality are also raising health concerns for sensitive groups.
According to the National Weather Service in Sioux Falls, locally heavy downpours may lead to ponding or brief flooding, especially in low-lying areas. Additional storms are likely Sunday evening with the strongest chances along I-29 and southeast toward Yankton and Brookings. Although the risk for severe weather is low, isolated downpours and gusty winds remain possible.
Air quality is being impacted by surface smoke lingering across the region. Visibility dropped early Sunday in Sioux Falls, and the haze may persist through the afternoon before lifting.
Looking ahead, the next organized thunderstorm threat builds Monday afternoon, with stronger systems possible by Tuesday. Forecast confidence remains low for exact storm strength and placement, but damaging wind or hail can’t be ruled out. Expect drier and sunnier conditions to return by midweek.
Spotter activation is not currently expected, but residents should stay weather-aware as conditions evolve.
