Sioux Falls, SD – Thunderstorms have developed over west-central South Dakota and are expected to progress eastward, bringing the potential for severe weather across the region tonight.
According to the US National Weather Service Sioux Falls South Dakota, the strongest storms and heaviest rainfall are anticipated along and south of Highway 18.
