The polar vortex is extensive coverage of low pressure and cold air surrounding Earth’s poles. When the vortex is strong and stable, the polar jet stream shifts northward, keeping the cold air ...
Starting in late December as a result of the southward shift of the polar vortex, extremely cold conditions froze the eastern United States in the last few days of 2017 as well as into the new year. Following a brief respite in mid-January, cold temperatures swung back into the eastern U.S. shortly afterwards.
A snowstorm on February 3–4 brought 0.5 to 4 inches (1.3 to 10.2 cm) of snow to parts of Western Washington, including the Puget Sound region, after a winter without measurable snowfall. It was caused by cold air arriving from the north alongside a low-pressure system, dropping temperatures to the 30s and 40s.
The term polar vortex can be used to describe two distinct phenomena; the stratospheric polar vortex, and the tropospheric polar vortex. The stratospheric and tropospheric polar vortices both rotate in the direction of the Earth's spin, but they are distinct phenomena that have different sizes, structures, seasonal cycles, and impacts on weather.

Prior to the events of January 2014, several studies on the connection between extreme weather and the polar vortex were published suggesting a link between climate change and increasingly extreme temperatures experienced by mid-latitudes (e.g., central North America). [89]
