When a polar vortex reached its frigid fingers down from the arctic in 2013-14, it gripped the Upper Midwest and caused one of the coldest winters in Minnesota history, sinking the North Star State into several long stretches of sub-zero temperatures.

Minnesotans are accustomed to cold winters, but the winter of 2013-14 was one of the coldest on record.

The state hadn’t seen such long stretches of below-zero weather in more than four decades.

Between December and March, the Twin Cities recorded 53 days on which the minimum temperature was at or below zero.

Farther north, though, things got really serious. International Falls tied its record for the most-ever days at or below zero degrees, with 92.

In addition to the cold air temperatures, Minnesota saw plenty of snowfall - and the wind chills were brutal.

Because of the cold and wind chills, several school districts set pre-pandemic records for the number of school days canceled. In some cases, buses wouldn’t even start.

During the winter of 2013-14, Lake Superior, the world’s largest freshwater lake by surface area, reached 95 percent ice coverage.

At least there’s plenty to do during the winter in Minnesota.
