Wider weather episode

Strong thunderstorms developed along a cold front across the Central and Lower Great Lakes during the late evening and overnight hours of August 24-25, 2023. These thunderstorms were in an environment of strong to extreme instability, along with sufficient low-level and deep-layer wind shear for organized and rotating thunderstorms. This allowed storms that developed over Michigan to organize into a fast-moving cluster of thunderstorms that produced extensive wind damage and a number of tornadoes between southern Lower Michigan and southwestern Pennsylvania, and Ohio.
