Christmas Day is normally a relatively quiet day in terms of the weather as we recently discussed but the week between it and New Year’s can be quite eventful. Among the highlights are a prolonged period of sub-zero temperatures that lasted nearly five days. Just five years ago a blizzard struck the region that snarled holiday travel on the air and the ground.

Looking back at Denver weather history, it is readily apparent that the week leading up to Christmas has historically been a very eventful one. There are certainly many of the snow and wind events we would expect to see. Most notable however are the major winter storms like the pre-Christmas storm of 2006 and of course what is arguably Denver’s most famous winter storm, the Christmas Eve Blizzard of 1982.

• For more on the Christmas Eve Blizzard of 1982, read our complete recap with photos here.

From the National Weather Service:

17-24

In 1924…a prolonged cold spell occurred after mild temperatures during the first half of the month. Most low temperatures dipped below zero with the coldest reading of 15 degrees below zero occurring on the 24th. The high temperature of only 5 degrees on the 18th was a record low maximum for the date.

18

In 1901…north winds were sustained to 52 mph with gusts to 58 mph behind an apparent cold front.

In 1973…a brief blizzard dumped heavy snow across metro Denver. Snowfall totaled 9.2 inches at Stapleton International Airport where north winds gusting to 53 mph produced much blowing snow. The storm forced many schools and businesses to close.

In 1996…a homeless man in Denver was found unconscious in his car suffering from exposure. The man’s body temperature was only 85 degrees when he was discovered. He died several hours later. Early morning temperatures had dipped to 9 degrees below zero.

Winds gusted to 72 mph in Golden Gate Canyon and to 71 mph at the National Center for Atmospheric Research in the foothills southwest of Boulder. West winds gusted to only 39 mph at Denver International Airport where the temperature warmed to a high of 53 degrees.

In 2002…only a trace of snow fell at the site of the former Stapleton International Airport. This…along with the trace of snow on the 5th…was the only snow of the month…ranking the month the 2nd least snowiest on record.

18-19 In 2012…a storm system brought moderate to heavy snow to the mountains and foothills west of metropolitan Denver and blizzard conditions to plains east of Denver metro area. The combination of snow and wind reportedly reduced visibility to just a few hundred feet at times…and resulted in several road closures including Interstate 70 east of Aurora. East of Denver gusty northerly winds ranged from 35 to 55 mph produced extensive blowing and drifting snow…ranging from 1 to 4 feet in depth. Storm totals ranged from 3 to 5 inches. In the mountain and foothills…the heaviest snowfall occurred along and north of I-70 and included: 12 inches at Genesee…9 inches near Eldorado Springs; 8.5 inches at Coal Creek Canyon…8 inches near Evergreen… with 6 inches at Eldora Ski Area…Idaho Springs… Gross Reservoir and Nederland. At Denver International Airport…1.7 inches of snowfall was observed. In addition…a peak wind gust to 35 mph was observed from the north on the 19th.

18-21

In 2010…a winter storm produced a 4-day period of moderate to heavy snow in the mountains. The combination of strong wind and heavy snow forced the closure of several mountain passes due to the threat of avalanches. The Amtrak train route… Which runs from Denver to California…was rerouted through Wyoming when Union Pacific closed its tracks along Interstate 70. Numerous accidents forced the closure of I-70 at times. The wind gusted to 60 mph over the higher mountain passes. Storm totals in the ski areas west of Denver ranged from 16 to 32 inches.

18-24

In 1998…a vigorous cold front with north winds gusting as high as 38 mph at Denver International Airport on the 18th dropped temperatures from a high of 51 degrees to a low of just 6 degrees before midnight. The arctic air mass that settled over metro Denver produced intermittent light snow and a week-long protracted cold spell that caused low temperatures to plunge well below zero for 6 consecutive nights. The coldest temperature was 19 degrees below zero on the morning of the 22nd. High temperatures climbed only into the single digits on 4 consecutive days…from the 19th through the 22nd. At least 15 people…mostly homeless… Were treated for hypothermia at area hospitals. The bitter cold weather was responsible…either directly or indirectly… For at least 5 fatalities. Three of the victims died directly from exposure. The cold weather also caused intermittent power outages. Following the cold snap… Thawing water pipes cracked and burst in several homes and businesses…causing extensive damage. Only one temperature record was set.

19-23

In 1990…a surge of very cold arctic air invaded metro Denver. Many temperature records were broken as the mercury remained at or below zero for 85.5 hours at Stapleton International Airport…making it the third longest period of subzero readings in 118 years of record keeping. On the morning of the 22nd…the mercury plunged to 25 degrees below zero…which equaled the all time record low temperature for the month set on December 24…1876. In the foothills southwest of Denver at tiny town…the mercury plunged to 33 degrees below zero on the morning of the 21st. On the same morning at Castle Rock the temperature dipped to 26 degrees below zero. During the period…other daily temperature records were set at Denver…including: record low maximum of 3 degrees below zero on the 20th and a record low of 17 degrees below zero on the 23rd.

Southwest winds gusted to only 24 mph at Denver International Airport.

In 2004…strong downslope winds developed over the eastern mountain slopes and spread over metro Denver. Peak wind gusts approached 100 mph along the foothills of Boulder County. In Superior…a 1200-square-foot section of roof was peeled off the gymnasium at Monarch High School. Two semi-trailers were toppled on Colorado highway 58 at McIntyre Street and another at c-470 and west Bowles Avenue. Two airplanes were damaged by wind-blown debris at Jefferson County Airport. The high winds forced the closure of State Highway 93 between Golden and Boulder for approximately two hours. Insurance agents estimated 650 to 850 homes suffered wind damage in the Boulder and Louisville areas. In addition…downed trees and power lines left about 1000 residents…mainly in the Boulder area…without electricity. At least three people suffered minor injuries in the storm.

20-21

In 1969…high winds caused widespread…but mostly minor damage to roofs…windows…and power lines and overturned some house trailers in areas along and just east of the foothills. Wind gusts of 60 to 70 mph were reported in Boulder and south of Boulder at Rocky Flats. A wind gust to 115 mph was measured in Boulder at the National Center for Atmospheric Research. At Stapleton International Airport…west winds gusted to 44 mph on the 20th and to 45 mph on the 21st. The warm Chinook winds warmed the high temperature to 56 degrees on the 20th and to 65 degrees on the 21st.

In 2006…a major blizzard buried greater metro Denver and the adjacent foothills in deep snow. A slow moving upper level low pressure center produced deep moist upslope flow over the high plains and against the eastern slopes of the mountains…allowing heavy snowfall to persist for 34 hours across metro Denver. Total snow accumulations ranged from 1 to 2 1/2 feet across the city and from 2 to nearly 4 feet in the foothills. Adding to the misery… Strong north winds sustained at 20 to 35 mph with gusts from 45 to nearly 60 mph produced much blowing snow and piled the snow into drifts from 6 to 12 feet high…closing businesses and bringing all transportation to a halt. The storm forced the closure of Denver International Airport for a total of 45 hours which snarled the nation’s air traffic system. This was the longest closure in the airport’s 12 year history. The closure stranded nearly 5000 travelers when 2000 flights were canceled. Many inbound flights were diverted to other airports…stranding even more passengers. Many of the stranded travelers failed to reach their final destinations until days after the airport re-opened due to fully booked flights during the holiday season. Police and national guardsmen rescued hundreds of commuters stuck in their cars…and sent them to temporary shelters set up by the Red Cross. All interstates and other major highways in and out of Denver were closed. Greyhound was forced to cancel all bus trips from Denver. Mail delivery was suspended. The Regional Transportation District suspended all metro Denver bus service for the first time since the March 2003 blizzard. The roof of a discount store in Aurora collapsed under the weight of the heavy snow. In Lakewood…a power outage left 5600 residents without electricity for a brief time. Metro Denver snowfall amounts included: 34 inches 10 miles southeast of Buckley AFB…32 inches in Littleton…30 inches in Thornton and near Castle Rock…29.5 inches near Parker…28 inches in Wheat Ridge…25.5 inches at centennial airport…25 inches at Niwot…24 inches in Aurora…22.5 inches at Greenwood Village… 22 inches in Arvada…21.5 inches in Lakewood…20 inches in Longmont…and 15.5 inches in Boulder. Snowfall measured 20.7 inches officially in the Denver Stapleton area. This ranked the snowfall as the 7th greatest in the city since 1946. North winds were sustained to 37 mph with gusts to 55 mph at Denver International Airport. In the foothills snowfall totaled: 42 inches at Conifer and 11 miles southwest of Boulder…40 inches at Evergreen…39 inches at Aspen Springs… 37.5 inches 8 miles north of Blackhawk…33 inches near Nederland…31 inches at Intercanyon and near Tiny Town…30.5 inches atop Buckhorn Mountain…30 inches near Indian Hills… 29 inches at Rollinsville…24 inches near Gross Reservoir and Ralston Reservoir…22.4 inches atop Crow Hill…and 20 inches near Georgetown. Snowpacked and rutted streets and parking lots persisted for a month or more after the storm and subsequent storms. The heavy snowfall created a snow removal controversy when many citizens complained that residential streets were not cleared in a timely manner in the city and in some suburban areas. This was in spite of the fact that tens of millions of dollars were spent on snow removal. In the city of Denver…snow cover of an inch or more from this storm and subsequent storms persisted for 61 consecutive days…through February 19…2007. This is the second longest period of snow cover on record in the city. Many homeowners who had extensive Christmas lights and decorations in their yards were not able to remove the lights because the wires were buried in deep snow and ice until the end of February or later.
