May 24 Landspout Spirals Over Cheyenne

A landspout - a type of tornado that is "smaller and weaker than tornadoes produced by supercells" appeared within city limits on May 24, 2023, shocking residents. The spout was visible over Dell Range Blvd. In response to the spout, F.E. Warren Air Force Base issued a warning on the base urging occupants to seek shelter.

Several Cheyenne residents captured the landspout on camera. Did you see the would-be twister appear over Cheyenne?
