Sioux Falls, South Dakota – Residents across central and eastern South Dakota should brace for scattered severe thunderstorms Tuesday afternoon through early Wednesday, with the greatest risk of hail, damaging winds, and isolated tornadoes in the central third of the state.
According to the National Weather Service in Sioux Falls, a Level 2 (Slight Risk) alert covers much of the region late Tuesday. The main hazards include hail up to the size of half dollars and wind gusts reaching 70 mph, particularly in areas along I-90 and south toward Nebraska. Storms could persist into the early hours of Wednesday, potentially causing rapid changes in weather conditions.
Key cities such as Mitchell, Huron, Brookings, and Yankton may experience downed tree limbs, power outages, and hazardous travel conditions. Tornado potential is low but not zero, so residents are urged to review safety plans. If driving, be prepared for sudden hail or debris on highways like US-81, and consider delaying non-essential travel during warnings.
Preparedness is crucial: charge electronic devices, secure outdoor items, and have multiple ways to receive alerts, including NOAA Weather Radio and mobile apps. If outside, identify the nearest sturdy shelter and move there quickly if a warning is issued.
Severe thunderstorm warnings remain possible through Tuesday night, and further advisories could follow as storms move south toward Nebraska.
