Next week’s pre-winter arctic plunge might be a sign of things to come for the Eastern U.S., as several key weather patterns will converge to bring early bone-chilling cold and potentially more snowstorms to the region.
According to the FOX Forecast Center, two weather patterns, La Niña and an easterly Quasi-Biennial Oscillation, will allow more rounds of arctic air that is typically trapped high above the North Pole to spill into the lower levels of the atmosphere and south into the Eastern U.S.
This frigid air is known as the “Polar Vortex.”
Air in the polar vortex sits in the stratosphere, some 10 to 30 miles above the Earth’s poles and intensifies during the winter, when a lack of sunlight cools air at this height to below -70 degrees Celcius.
The polar vortex typically remains locked over the North Pole and Northern Canada as well as up in the stratosphere, separated from warmer air in the lower level of the atmosphere, the troposphere—that makes up the weather we experience.
While the El Niño–Southern Oscillation (ENSO) is typically the driver of most weather, another lesser-known climate pattern, the Quasi-Biennial Oscillation (QBO) will play a big role early this winter.
The QBO refers to the direction winds are blowing in the stratosphere around the equator, which in turn will influence the strength of the Polar Vortex.

Well, it all started back in the day when those flying machines started getting popular and creating all of their jet streams that now run amuck all over the place.
As the almost defunct Farmer’s Almanac would say, “Winter is on the way”
And Christmas songs also noted it with lyrics like, “Jack Frost nipping at your nose”....
Polar Vortex can be wicked in 1981 maybe 1982 I was in Michigan it was heavy snow storms lake Michigan froze over the waves were froze to about 8 feet high and the wind chill index was 58 below zero.
I demand Trump rename them to The Boy and The Girl.
Why aren’t wokesters demanding it is renamed Xl Ninx and Lx Ninx?
