'High risk' severe weather days aren't reserved for Tornado Alley: Minnesota can get them, too
Violent, long-track tornadoes are possible Monday in Texas and Oklahoma, with the threat so severe that the Storm Prediction Center has issued a rare "high risk" for damaging storms.
It's the first high risk issued for anywhere in the country in two years. There were four such days in 2017 but none in 2015 or 2016. Bottom line: These days don't come around often, but when they do they have a tendency to live up to the hype.
And they're not just reserved for Tornado Alley. They can happen in Minnesota, although they're so rare that meteorologists with the Twin Cities office of the National Weather Service asked around and said: "Nobody here can remember the last one."
So, we turned to Wikipedia for information and found that there have been seven high risk days in Minnesota in the last 30 years, most recently in 2008.

As you can see in the severe risk outlook for that day, parts of southern Minnesota was under a high risk for major storms. But it was tornadoes the morning of June 6 that did the most damage.

There isn't an image to show precisely where the high risk area was, but the date produced the destructive Chandler-Lake Wilson F5 tornado in southwest Minnesota. According to the National Weather Service, the tornado destroyed more than 75 homes and caused more than $50 million damage. Forty people were injured and one person was killed.
The tornado produced estimated wind speeds in excess of 260 mph.
