On June 3–4, 1958, a destructive tornado outbreak, also known as the Chippewa Valley Tornado Outbreak, affected the Upper Midwestern United States. It was the deadliest tornado outbreak in the U.S. state of Wisconsin since records began in 1950. The outbreak, which initiated in Central Minnesota, killed at least 28 people, all of whom perished in Northwestern Wisconsin. The outbreak generated a long-lived tornado family that produced four intense tornadoes across the Lower Chippewa Valley, primarily along and near the Chippewa and Eau Claire rivers. The deadliest tornado of the outbreak was a destructive F5 that killed at least 21 people and injured 110 others in and near Colfax, Wisconsin.
