The SPC Database lists 3 tornadoes on October 22, 1972. We look at one of those in this summary. It was given a rating of F3. Thomas Grazulis in Significant Tornadoes believes the damage was more in the F2 range. That was just one discrepancy with this event.
As with some past events, I had to put on my Sherlock Holmes hat with this one and do some sleuthing to figure out what exactly happened. The SPC has one tornado listed on August 3, 1963 and this is it: An F3 with a path length of 0.1 miles in Allegheny County, PA. There are several discrepancies that expand across our different sources.
It is considered the most destructive tornado in Wyoming’s history. An F3 crossed through the northern parts of the Cheyenne housing and airport areas. Thomas Grazulis in Significant Tornadoes states this could have been a “minimal F4” tornado. And the NWS in Cheyenne originally believed that was an appropriate rating. Explore the history!
