The National Weather Service has confirmed that four weak tornadoes touched down in the Twin Cities area Wednesday, bringing winds between 70 mph and 85 mph.
The weather service damage assessment teams finished their work by Thursday evening, and confirmed three F0 tornadoes and a slightly stronger F1 tornado touched down in the storm.
One F0 touched down in south Minneapolis then moved into downtown. Another hit about 40 miles north of St. Paul, in North Branch near the middle school. The third was just outside Hudson, Wis., and it downed several large trees.
A slightly stronger F1 tornado touched town on state Highway 61 in Cottage Grove, uprooting or shearing off several trees 2 feet to 3 feet in diameter.
The weather service ranks tornadoes on a scale of F0 to F5, the most powerful.
