Blame a Sudden Heat Spike for the Arctic Temperatures in the Midwest

"....Around Jan. 2, part of the stratosphere experienced a rapid rise in temperature of 50 degrees Fahrenheit in just a few days, NOAA says. The process—called a sudden stratospheric warming—split the unstable polar vortex.
When part of the polar vortex broke off, pockets of arctic air moved south, which is what is causing the current cold snap, meteorologists say.
Some climate scientists believe that warming in the Arctic due to climate change may be destabilizing the polar vortex, according to a 2017 study in the Bulletin of the American Meteorological Society, creating more extreme weather events. Cold temperature extremes, however, have become less severe and less frequent overall in recent decades, while extreme heat events are now more severe and more frequent."..."
