A polar vortex will bring brutally cold temperatures and an arctic blast to much of the U.S. next week
Snow and winds are likely to trigger flight cancellations and cause headaches for people traveling to DC for Inauguration Day.
A polar vortex is coming toward the U.S. Here’s how it will impact Utah
The polar vortex is expected to reach the Utah-Idaho border sometime in the late afternoon and evening Friday as it continues to move south. As it moves through parts of the state, it will produce small snow showers, bringing more snow to the region before drier conditions return.
How climate instability may be disrupting the polar vortex
These severe cold events occur when the polar jet stream – the familiar jet stream of winter that runs along the boundary between Arctic and more temperate air – dips deeply southward, bringing the cold Arctic air to regions that don’t often experience it.
Wind chill temperatures as low as -15 degrees anticipated in central Ohio during next week's polar vortex

What’s the polar vortex and how cold will it be in Metro Detroit next week?
A disruption in the polar vortex is about to send an Arctic air mass from Siberia as far south as Florida. Yes, Siberia—and it’s as dramatic as it sounds. As many as 47 states will experience unseasonably cold temperatures. Some areas will be hit with dangerous wind chills as low as 40 below zero.
Polar vortex to send bitter cold to the U.S. including DC area
The polar vortex is a ring of cold air that typically circles the Arctic. A strong jet stream essentially acts like a fence, keeping it locked there. If there's any weakening in the jet stream (the fence), the frigid air can become unstable and spill out. This sends the normally trapped cold air much farther south.

Arctic blast from polar vortex to send temperatures plunging across the U.S. Here’s how cold it will get.
An arctic blast will send temperatures across the United States plummeting as bitterly cold air that originated in Siberia will arrive from Canada by week’s end, bringing with it dangerously cold wind chills for millions of Americans.
Siberian air is descending on Canada. Here's what to know about the 'polar vortex'
The intense cold snap about to settle over most of Canada and the U.S. has been dubbed a “polar vortex’, but Environment Canada Senior Climatologist David Phillips says it could just as easily be called “Arctic air or Siberian air.
