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 low temperature records in a number of areas. This 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. Mount Mitchell, in North Carolina recorded an all time record low of -34 °F °C. Meteorological synopsis From Sunday, January 20, 1985, until Tuesday, January 22, 1985, the polar vortex, coupled with a large ridge of high pressure, moved polar air into the United States as far south as Arizona, Texas, and northern Florida. Unlike with cold-air systems, a pattern of self-modification did not immediately occur, and seasonable temperatures were absent for a number of days, a rarity in forecasting. The Arctic air mass started moving into the United States on the evening of January 19 and into the morning of January 20, 1985. In Chicago, Illinois, a record low of -27 °F °C combined with 25 mph km/h winds, to produce a wind chill of -60 °F °C.http://www.crh.noaa.gov/lot/?n=Jan_wx_trivia Chicago, IL St. Louis, Missouri saw a low of -18 °F °C, and Pittsburgh, Pennsylvania had a low of -18 °F °C, the coldest morning since 1899.NWA Pittsburgh statistics In Cincinnati, Ohio, the morning temperature of -21 °F °C tied for the fourth-lowest minimum temperature in the city's history, outdone by a cold mass the year before and a blizzard in 1977.RECORDS FOR CINCINNATI Cleveland, Ohio fell to -18 °F °C, which was at the time a record low.Cleveland Normals and Records for January Memphis, Tennessee recorded a low of -4 °F °C, setting a record low for that day.

New York City's Central Park recorded a low of -2 °F °C, breaking that date's record.CENTRAL PARK NEW YORK CITY RECORDS 1869-2008 Washington National Airport recorded a low of -4 °F °C and Washington Dulles Airport a low of -6 °F °C on the morning of January 21.DAILY NORMALS AND RECORDS FOR THE MONTH OF JANUARY FOR WASHINGTON DC Farther south, Roanoke, Virginia, set a record low of -11 °F °C. Nashville, Tennessee dropped to -17 °F °C, and Knoxville, Tennessee recorded a record low of -24 °F °C. All-time low temperature records were also set well into interior sections of the deep South, such as in Charlotte, North Carolina, where temperatures were recorded as low as -5 °F °C; Macon, Georgia, with a record low of -6 °F °C; and Jacksonville, Florida with a record low of 7 °F °C. Gainesville, Florida, with a low temperature of 10 °F °Chttp://www.srh.noaa.gov/jax/?n=extremes_gnv extremes gnv was its coldest temperature since the Great Blizzard of 1899 (when it had reached a low of 6 °F °C). Atlanta, Georgia saw a low of -8 °F °C, setting a record for the month of January as well as for the 20th century, and was only one degree shy of its all-time record (since 1878) set in February 1899.Average Weather for Atlanta, GA Miami, Florida, whose average low in late January is 61 °F °C, recorded a record low of 37 °F °C on January 21, 1985, and 34 °F °C on January 22, 1985.
