A multi-cell severe weather event was forecast for Jefferson and Saline counties in southeast Nebraska. At 7:40pm, a tornado warning was issued for a tornadic thunderstorm located over Swanton - about 17 miles north of Fairbury, NE. The storm birthed a nearly stationary supercell, which rotated and recycled over the corridor for multiple hours.

A disturbance moved across the Northern Plains, clearing over Wyoming and the Black Hills which allowed storms to redevelop along a boundary across southern South Dakota. Several became supercells, with one producing a rain-wrapped EF-1 in Tripp County near Ideal, SD. The tornado had a max width of 436 yards and stayed on the ground for 24 minutes, tracking a distance of approximately 10.3 miles with winds reaching 100mph.

A severe weather forecast was issued for Walton County, Florida in anticipation of a progressive squall line moving in from the northeast. The squall produced two tornado-warned segments (with at least one brief tornado), waterspouts, and localized straight-line winds downing several power lines and trees.
