Every weekend in the run up to New Year, I thought it might be good to take a step back in time and relive some of America and Europe’s very worst, most extreme winters of the last 100+ years.
Thought I would start off with 1985 for the US which saw a record mild December in the East!
January 1985 Record-breaking Cold

Arctic air was pushed southward into the northern Plains and Great Lakes on January 18th by a building ridge of high pressure over northern Canada. The upper level high became unusually strong over Canada, diverting the jet stream on a looping path southward across the United States. The polar vortex dropped into the Great Lakes region on January 19th; this helped accelerate the movement of intensely cold air southward. The arctic cold front reached the Carolinas during the morning of January 20th and by that evening had pushed through all of Florida and into Cuba. Across North and South Carolina the coldest morning of the event was January 21, 1985, a date which shows up in most city’s record books for the lowest temperatures ever observed.

Local impacts from the exceptionally cold weather included record-high electricity usage which exceeded the previous record by 12 percent, burst water pipes in municipal buildings, homes and businesses, and at least one fatality in the town of Teachey, NC due to exposure to the cold temperatures. There were many house fires around the region due to improper use of space heaters. Firefighters faced the unusual problem of their water hoses freezing while attempting to fight fires. Some local school systems operated on delayed schedules while others canceled classes entirely until the weather warmed. The fishing vessel Miss Radford sank in the Pamlico Sound during frigid winds; the three crew members were rescued by the U.S. Coast Guard. In Wilmington the temperature fell to 5 degrees on the morning of January 21, 1985; this tied the all-time record low for Wilmington orginally established on February 13, 1899. The Christmas Snowstorm of 1989 just four years later dropped the temperature to 0 which set a new all-time record low for the Port City.

Winter 1985 cold wave
The Winter 1985 cold wave[1] was a meteorological event, the result of the shifting of the polar vortex further south than is normally seen.[1] Blocked from its normal movement, polar air from the north pushed into nearly every section of the eastern half of the United States and Canada, shattering record lows in a number of areas.[1] 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.[2]

Meteorological synopsis[edit]
From Sunday, January 20, to 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 Florida.[1] Unlike most cold air systems, a pattern of self-modification did not immediately occur, i.e. seasonable temperatures were absent for a number of days, a rarity in forecasting.[1]
The Arctic air mass started moving into the United States on the evening of January 19 and the morning of January 20. An early victim of the air mass was the city of Chicago, which recorded a record low of −27 °F (−33 °C), coupled with 25 miles per hour (40 km/h) winds to produce a wind chill of −77 °F (−61 °C), also never recorded before. The wind chill calculation was adjusted in 2001, which would make the value about −60 °F (−51 °C) on the new scale.[3] St. Louis saw a low of −18 °F (−28 °C). Pittsburgh woke up that morning to find a low of −18 °F (−28 °C), the coldest morning since 1899.[4] In Cincinnati, the morning temperature of −21 °F (−29 °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.[5] Cleveland fell to −18 °F (−28 °C), which was at the time a record.[6] Memphis recorded a low of −4 °F (−20 °C), setting a record low for that day. The coldest temperature in the contiguous states on Jan. 21 was −24 °F (−31 °C), in the unlikely location of Akron, Ohio.[7]
The mass moved east and south during the day on January 20, resulting in frigid air for most of the Eastern Seaboard starting on the morning of January 21. New York City‘s Central Park recorded a low of −2 °F (−19 °C), breaking that date’s record.[8] Washington National Airport set a record of −4 °F (−20 °C) for the morning of January 21 and a record low for the prior date of −2 °F (−19 °C).[9] It was the Southern United States that felt the biggest brunt, unaccustomed as they are to the Northern states’ winter air. Roanoke, Virginia set a record low of −11 °F (−24 °C), and the campus of the University of Tennessee at Knoxville, Tennessee, recorded a record low of −24 °F (−31 °C).[1] Tennessee’s state capital, Nashville, dropped to −17 °F (−27 °C), while all-time records were set well into interior sections of the deep South, such as −5 °F (−21 °C) in Charlotte,[1] −6 °F (−21 °C) in Macon, Georgia,[1] 7 °F (−14 °C) in Jacksonville, Florida,[1] and 10 °F (−12 °C) in Gainesville, Florida[10] (coldest since 6 °F (−14 °C) in 1899). Atlanta saw a low of −8 °F (−22 °C), setting a record for the month of January and for the 20th century, missing by just one degree the all-time record (since 1879) set in February 1899.[11] Even Miami, whose average low in late January is 60 °F (16 °C), recorded a low of 34 °F (1 °C) on the 21st and 30 °F (−1 °C) on the 22nd, both record lows for the date, the latter being one of only 10 times the city has been that cold since 1895.[12][13]
Ferocious cold in February 1985 set two more state record lows in the Mountain West. Utah’s −69 °F (−56 °C) was the second-coldest temperature ever recorded in the “lower 48” states, just above Montana’s record of −70 °F (−57 °C) in 1954. Colorado’s −61 °F (−52 °C) broke the old record of −60 °F (−51 °C), also on February 1.
Impact and aftermath[edit]
The cold wave brought human fatalities, deaths of wild and domesticated animals, crop losses, and infrastructure damage to homes, municipality and industrial sites. At least 126 deaths were blamed on the cold snap.[14] Some 90 percent of the citrus crop in Florida was destroyed in what the state called the “Freeze of the Century.”[15] Florida’s citrus industry suffered $1.2 billion in losses ($2.3 billion in 2009 dollars) as a result of the inclement weather, which killed nearly every citrus tree in central Florida, and forced the industry permanently into southern Florida.[16] The public inauguration of President Ronald Reagan for his second term was held in the Capitol Rotunda instead of outside due to the cold weather, canceling the inaugural parade in the process. (Because Inauguration Day fell on a Sunday, Reagan took a private oath on January 20 and the semi-public oath on January 21.)[17]
