5 tornadoes confirmed in Friday’s outbreak in southeastern Minnesota

The National Weather Service confirmed that at least five tornadoes touched down in southeastern Minnesota on Friday, including four that hit Olmsted County. At least another three twisters were confirmed in southwestern Wisconsin.

The NWS was still analyzing data and other information to determine if more tornadoes occurred in the area.

The storms started Friday afternoon, with the first tornado touching down north of Sargeant in Mower County around 1:45 p.m. The short-lived EF0, with top wind speeds of 80 mph, traveled about 3 miles northeast into rural Dodge County near the unincorporated town of Oslo. It lasted for about five minutes in total, the weather service says, and caused minor damage to a grain silo before dissipating.

A new tornado formed a few minutes later, less than a mile away south of Oslo. The storm was also considered an EF0, with wind speeds around 80 mph. Lasting less than 10 minutes, it traveled 4 miles into Olmsted County, causing light damage to farm outbuildings and trees.

The line of storms seemed to pick up intensity as it entered Olmsted County.

Around 2:17 p.m., the EF2 tornado that would later hit Marion Township first touched down just northeast of Stewartville. The weather service estimates that the twister had wind speeds of about 130 mph and traveled nearly 10 miles northeast, before dissipating around 2:31 p.m. Multiple homes were severely damaged with roof removal and partially collapsed exterior walls.

An EF1 tornado was also confirmed to have hit near Potsdam around 2:30 p.m.

The first portion of the tornado was weak, the weather service said, with mainly EF0 damage. On the second portion of the 12-mile track, the tornado intensified to produce approximately 100 mph winds with tree and farm outbuilding damage. It lifted around 2:54 p.m.

A second EF2 tornado was confirmed in Olmsted County around 2:46 p.m. about 5 miles east-northeast of Viola and traveled about 7.5 miles, ending in Wabasha County, a few miles south of Plainview, around 3 p.m. Maximum wind speeds were around 125 mph. The storm affected mainly rural areas and damaged trees and outbuildings. One farmhouse lost a roof and a garage roof, the weather service said.

No injuries were reported in the Minnesota-Wisconsin outbreak.

Friday was a historic day for the NWS La Crosse office, which issued 26 tornado warnings – the most for any one day since the office opened in 1995.
