Amid the so-called “polar vortex” that’s affecting the Midwest, some have noted that Chicago will be colder than Antarctica this week, namely on Wednesday.
It comes as about 250 million people will face temperatures below freezing this week, and about 90 million of those people will endure temperatures below zero degrees Fahrenheit.
Another 25 million could experience temperatures of 20 degrees below zero, said meteorologist Ryan Maue of Weathermodels.com.
With wind chills factored in, temperatures will feel like 40, 50, or even 60 degrees below zero in some places around the United States, but namely in the Midwest.
“From Tuesday through Thursday, expect frigid temperatures and bitterly cold wind chills, likely leading to widespread record lows and low maximum temperatures,” said the website.
For much of the Midwest, including Chicago, Detroit, Minneapolis, Milwaukee, and Des Moines, a wind chill warning was in effect.
The forecasts have prompted reports saying that Chicago will be “colder than Mount Everest” and “Antarctica” on Wednesday. The expected high temperature will be about 12 degrees below zero on Wednesday morning and a low of 20 below zero during the night.
Hundreds of Michigan schools were closed Tuesday, including in Detroit, while Chicago Public Schools canceled Wednesday classes because of the anticipated cold snap. “You’re talking about frostbite and hypothermia issues very quickly, like in a matter of minutes, maybe seconds,” said Brian Hurley, a meteorologist with the Weather Prediction Center.
The unusually frigid weather is attributed to a sudden warming far above the North Pole. A blast of warm air from misplaced Moroccan heat last month made the normally super chilly air temperatures above the North Pole rapidly increase. That split the polar vortex into pieces, which then started to wander, said Judah Cohen, a winter storm expert for Atmospheric Environmental Research.
