| March 2026 | Tornado (EF0) | Ahern | - | An anticyclonic satellite tornado occurred north of Hopkins Park. High-resolution satellite imagery depicted swirl marks across multiple fields in the general vicinity of Baseline, S 13000E, and N 13500E Roads in a counter-clockwise looping path. Based on radar imagery and swirl patterns, the tornado appeared to be a anticyclonic tornado that initially moved north, stalled, and then turned southward before ending just north of a residence on S 13000 E Road, less than 300 yards southwest of the start location. There is no known damage that was caused by the tornado. |
