The May 13, 1980 Kalamazoo Tornado

Five people were killed and 79 were injured when a F3 tornado struck Kalamazoo, Michigan on May 13, 1980. This case study examines large scale synoptic conditions over the United States on May 13th and other data in an attempt to reconstruct the storm environment as accurately as possible. All of this data is tied together with our research findings from developing the Significant Tornado Climatology for Lower Michigan, in an attempt to better understand the environment in which this killer tornado developed.
