When was the most recent polar vortex?
January–February 2019 North American cold wave. In late January 2019, a severe cold wave caused by a weakened jet stream around the Arctic polar vortex hit the Midwestern United States and Eastern Canada, killing at least 22 people.
When was the polar vortex in the Midwest?
January 2019
In January 2019, temperatures in the upper midwest plummeted—and we’re talking mercury dropping down into the -60 degrees Fahrenheit range—thanks to a polar vortex. Conditions deteriorated so quickly that the U.S. Postal Service suspended service in 10 states.

What is a polar vortex 2020?
The Arctic polar vortex is a band of strong westerly winds that forms in the stratosphere between about 10 and 30 miles above the North Pole every winter. The winds enclose a large pool of extremely cold air. (There is an even stronger polar vortex in the Southern Hemisphere stratosphere in its winter.)
Is a polar vortex coming 2021?
Stratospheric Polar Vortex returns for Winter 2021/2022, together with a strong easterly wind anomaly high above the Equator, impacting the Winter season. A new stratospheric Polar Vortex has now emerged over the North Pole and will continue to strengthen well into the Winter of 2021/2022.
How long does a polar vortex last?
Those individual vortices can persist for more than a month. Volcanic eruptions in the tropics can lead to a stronger polar vortex during winter for as long as two years afterwards.
How cold can a polar vortex get?
They blow from west to east with sustained speeds easily exceeding 100 mph (160 kph). In the darkness of the winter polar night, temperatures within the polar vortex can easily get lower than minus 110 F (minus 79 C). Fortunately for everyone, the stratospheric polar vortex itself won’t appear outside your front door.
What’s the hottest it’s ever been in Missouri?

Winter will be warmer and drier than normal, with below-normal snowfall. The coldest period will be from late December into early January, with the snowiest periods in late November, late December, and early January. April and May will have near-normal temperatures and be rainier than normal.
Will we have a polar vortex in 2022?
A new stratospheric Polar Vortex is emerging over the North Pole, powering up for #Winter 2021/2022. It will combine its strength with a negative wind anomaly high above the Equator (QBO) and the La Nina, making an energetic mix of weather dynamics.
Will the polar vortex return in 2020?
Colder air is coming to the U.S. thanks to the polar vortex. Late in 2020 and early in 2021, AccuWeather meteorologists warned that a weakening of the polar vortex was coming and a major southward discharge of cold air would follow during the second half of January.
What states will be affected by the polar vortex?
Freezing temperatures will hit states ranging from Texas to Washington, D.C. Icy rain and snowfall are expected to affect about 50 million people this week. Southern states warn that such severe weather may impair travel and power.
