A strong blast of arctic air from Canada is expected to hit the eastern United States this week, beginning a week of extreme temperatures across the region that will hit to 100 million Americans with the coldest air of the winter season.
Arctic winds, often referred to as the polar vortex, occur when rotating air from Earth’s polar regions becomes unstable and moves into midlatitude areas. It is from here that these extreme temperatures escape the parameters of the polar areas and make their way to North America, resulting in atypically cold temperatures in certain regions. Areas of low atmospheric pressure face dangerous cold snaps and higher occurrences of snow.
According to reports by FOX Weather, New York, Washington D.C., and Pittsburgh are likely to be hit with the coldest of the winter thus far on Monday and Tuesday. The fervent freeze, elevated by hazardous wind chills, will make for ultra-harsh conditions for cities already facing sub-zero temperatures this January.
