What the National Weather Service wrote

A storm chaser shared a video evidence of multiple brief touch downs of suction vortices. The chaser video shows three distinct tornado locations along this path. No reports of damage have been received. The touch downs were very sporadic along a path of 8 miles.

The wider storm

A strong storm system and its attendant surface low moved across the area during the late afternoon and evening hours. This led to a tornado briefly touching down multiple times as a storm moved eastward near the town of La Harpe. The tornado was rated EF-U as there were no visible signs of damage.

Began near Durham (40.5776, -91.0899).
