Overview
A northeastward moving Quasi-linear Convective System, or QLCS Squall Line, developed in northeast South Dakota and tracked across portions of extreme southeast North Dakota, west-central Minnesota, and into southern portions of northwest Minnesota from mid-afternoon into the evening hours.
The system produced a variety of downburst winds, surface squalls, and several occurrences of vertically elongated squalls which were sustained as brief tornadoes. Rainfall was also notable, with several locations receiving more than one inch.
