Rain showers quickly turned severe Thursday evening in southwest Minnesota.
"The atmosphere wasn't particularly unstable," Borgoff said. "The wind shear was relatively weak as well so you typically don't expect to see violent thunderstorms in that environment."
A turkey barn was flattened in the storm along Highway 60 in St. James. More damage was reported as the storm made its way through Redwood County into Brown and Watonwan Counties.
The tornadoes that hit in those counties were measured as EF0, which have wind speeds of 65 to 85 miles per hour.
"It was just one thunderstorm that became massive very quickly," Borgoff said.
A team is headed down to the impacted areas to investigat the damage. They'll try to determine the tornado's rating during that time.
Severe weather is possible Friday across much of western and southern Minnesota, but it shouldn't be as severe as Thursday night's storms.
