Early 2014 North American cold wave
The 2014 North American cold wave was an extreme weather event extending from January to April 2014, and was also part of an unusually cold winter affecting parts of Canada and the Eastern United States. The event occurred in early 2014 and was caused by a southward shift of the North Polar Vortex. Record low temperatures also extended well into March.On January 2, an Arctic cold front initially associated with a nor'easter tracked across Canada and the United States, resulting in heavy snowfall. Temperatures fell to unprecedented levels, and low temperature records were broken across the United States. Business, school, and road closures were common, as well as mass flight cancellations. Altogether, more than 200 million people were affected, in an area ranging from the Rocky Mountains to the Atlantic Ocean and extending south to include roughly 187 million residents of the Continental United States.
