The front that moved through our area on Wednesday June 9th maintained its identity and began to move north as a warm front during the afternoon of the 13th. The first cell of the day became a long-lived supercell. This storm moved through the Midland and Bay City areas, over the south end of Saginaw Bay, and into Huron county before moving out over the open waters of Lake Huron. Later in the afternoon and during the evening a nearly solid line of storms developed along a north-south surface trough over western lower Michigan. These storms developed bowing characteristics as they moved into southeast Michigan and generated some straight-line wind damage. The Midland Fire Department called out two extra crews to answer about 30 storm-related calls of downed wires, broken utility poles and fallen trees. At least two trees crashed into homes.
