On May 21st, 2024, a violent tornado would tear through the town of Greenfield, Iowa. This highly documented tornado would yield the fastest tornadic wind speeds ever observed with radar, but despite this, would earn an EF4 rating based on the damage alone. This is a forensics engineering-based damage analysis of the Greenfield EF4 Tornado.
