| Episode Narrative | An unstable warm sector with MUCAPE up to 2000-2500 J/kg developed during the afternoon between an advancing cold front across southeast South Dakota, and a gangly warm front extending into southwest Minnesota. An approaching weak impulse spurred rapid development of multiple rounds of storms near the warm front, initially discrete, with upscale growth into short bowing segments. Secondary development occurred during the evening along the cold front, which evolved into a slow-moving linear system with hail, wind, and heavy rainfall with shear vectors increasingly parallel to the boundary. |
| Event Narrative | Another brief tornado spun up 4 miles east-northeast of Dovray, around one-third mile southeast of the intersection of 151st Street and 290th Avenue. The tornado traveled north over open fields causing damage to crops, and dissipated just south of 171st Street, 5 miles northeast of Dovray. From Sentinel satellite imagery, the average path width was found to be 20 yards. |
