caption_attribution_description: English: A map of the United States on January 21, 1985, detailing unusually cold temperatures for various cities as the January 1985 Arctic outbreak was in full effect. Numbers on the top depict the day's high temperatures in degrees Fahrenheit, while the numbers on the bottom denote the lowest.
context_page_description: The 1985 North America cold wave was a meteorological event, the result of the shifting of the polar vortex farther south than is normally seen. Blocked from its normal movement, polar air from the north pushed into nearly every section of the central and eastern half of the United States and Canada, shattering record lows in a number of areas. The event was preceded by unusually warm weather in the eastern U.S. in December 1984, suggesting that there was a build-up of cold air that was suddenly released from the Arctic, a meteorological event known as a mobile polar high, a weather process identified by Professor Marcel Leroux.
