On May 28, 2025, the Tempest Tours team captured what some are calling “The storm of the century.” The supercell thunderstorm tracked near Slapout, Oklahoma, in the evening and was captured on video by senior tour director Bill Reid. What makes the storm special is the exceptional “structure” it exhibits. This type of storm is called a “mothership supercell” since its circular shape mimics the look of an alien flying saucer. The shape is caused by wind shear, which causes the entire storm to spin counterclockwise.
