Officials warned of almost instant frostbite while temperatures in the region fell below freezing Wednesday. Some state offices are closed and postal workers do not deliver mail in 10 states. Thousands of flights have been canceled as well as dozens of train services, most to and from Chicago.
About 212 million people, 72% of the continental population of the United States, will see their temperatures drop below zero in the next few days. And more than 83 million Americans – about 25% of the US population – will experience subzero temperatures between Wednesday and Monday.
With at least five deaths related to the extreme conditions observed this week, authorities are urging people to rank, stay indoors and watch the elderly and vulnerable in what the experts describe as "the coldest air of a whole generation".
While most parts of the Midwest will experience freezing temperatures, Chicago will be the "epicenter" of extreme cold, "said CNN meteorologist Dave Hennen.
Chicago could reach a record-breaking temperature of 27 below zero by Thursday morning It is expected that on Wednesday it will reach 15 below zero
The Chicago National Weather Service tweeted Tuesday night that temperatures had already begun to drop.
"Chicago officially fell below freezing before 6 pm at O & # 39; Hare and may not return to zero until Thursday night, "he said.
It will be so cold that people in the Chicago area have an interest in warming up in parts of Antarctica. Priestley, in Antarctica, will have a maximum temperature Wednesday of 6 degrees Fahrenheit and a minimum of 7 below zero.
According to FlightAware.com, more than 2,700 flights involving US airports are canceled for Tuesday and Wednesday, including approximately 1,550 flights to and from Chicago airports.
Amtrak also canceled all services to and from Chicago Wednesday due to weather conditions, including short-distance trains and long-distance night trains. He said he usually operates 55 trains a day to and from the Chicago hub.
Mail delivery will also be canceled in Illinois, Iowa, Minnesota, North Dakota, South Dakota, Wisconsin and parts of Kansas, Missouri, Montana, and Nebraska. .
In Minnesota, frostbite can strike in minutes
Freezing temperatures are not the only concern. In Minnesota, a strong wind could cause wind chill near 70. In Ponsford, the wind chill was 66, said CNN meteorologist Michael Guy.
"These are VERY HAZARDOUS conditions that can cause frostbite on exposed skin in just five minutes and where wind chill values are below -50", tweeted the National Weather Service. "The best thing to do is to limit your time to the outside."
Hennen describes it as "the coldest air of a whole generation". Temperatures will dip 20 to 40 degrees below zero between Tuesday and Thursday in the Upper Midwest, Hennen said. In northern Minnesota, wind chill was expected to fall to 65-70 degrees below zero, which would be comparable to the coldest cooling ever recorded in the state (71 below) in 1982.
