The severe storms that developed in southwest Minnesota on Thursday produced three tornadoes, according to a report from the National Weather Service.
"Preliminary results from damage surveys identified three tornadoes. An EF-1 tornado occurred in Redwood county between Redwood Falls and Wabasso. An EF-0 tornado occurred in Brown County two miles south of Leavenworth. An EF-0 tornado occurred in far northern Watonwan County about a half mile southeast of Godahl. There were also several reports of wind damage and large hail."
Storms were not forecast to reach severe levels on Thursday, but the weather service notes in the official storm report that conditions became favorable and there was just enough turning of the winds for thunderstorms to produce tornadoes.
Here's a radar replay. The two screens show radar reflectivity (heavy rain, hail) and storm velocity (wind direction).
Fortunately, the tornadoes struck in rural areas and didn't go through any towns, although at least a couple of farm sites just south of Redwood Falls were significantly damaged, according to WCCO.
The Storm Prediction Center out of Oklahoma is watching for isolated strong to severe storms in parts of southern Minnesota on Saturday, with more frequent bouts of strong storms possible after a quieter period from Sunday to Wednesday.
