That's not a metaphor. The polar vortex has descended upon Chicago, promising temperatures below -17°C tomorrow and Friday in the coldest December in years:
While the deep chill will be powered by the infamous polar vortex — the circulation of air around the Arctic Circle — meteorologists don't believe we're headed for anything like the winter of 2013-14 when Chicago suffered through its coldest four-month period ever. The polar bear at the Lincoln Park Zoo wouldn't even venture outdoors.
But Tom Skilling, WGN-TV's meteorologist, said people should not jump to conclusions from this week, when the high Thursday will be in the single digits. Friday will be warmer, but there will be snow and maybe freezing rain over the weekend.
"This week is going to have the coldest air most of us have felt in 11 months," Skilling said. "It's going to be brutally cold for the Bears game on Sunday. But there's no reason to believe that, because we’re in a current cold spell, that this by any means sets the tone for the rest of the winter."
So the winter might be like Donald Trump? Objectively bad, but maybe not as bad as Hitler?
