Only two weeks ago, Badgers gathered in Camp Randall on a sunny 70-degree game day, but come Sunday, they’ll see a second round of polar vortex temperatures that became all too familiar last winter.

Meteorologists are predicting the Midwest will experience the most severe effects of the frigid weather pattern from Nov. 9 until Nov. 14, according to an AccuWeather report.

As defined by AccuWeather, a polar vortex is “a large pocket of very cold air” located in the polar region of the Northern Hemisphere, but sometimes it makes a southward shift, causing icy temperatures in Canada and the United States.

Accompanied by forceful winds, temperatures will feel closer to single degree or low teen digits. This will heighten the risk of hypothermia and frostbite in the North, according to the report.

Last winter, the polar vortex froze over Madison, leading to videos like this one from U.S. Rep. Mark Pocan, D-Madison, below.

The Badger Herald offered tips last year to those hoping to stay warm.
