The period around the Christmas holiday has historically been a pretty eventful one for the Denver metro area. Our look back at this week in Denver weather history showcases a wide variety of extreme conditions. From powerful, damaging winds to extreme cold to monstrous blizzards, we can and have seen it all.
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.
18-24
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. The high temperature of only 7 degrees on the 19th set a record low maximum for the date.
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.

Two people froze to death in Denver; both were found outside dead of exposure. Numerous cases of frostbite were reported. Hundreds of water pipes broke from the intense cold…water mains and natural gas lines also fractured…and electricity consumption reached record levels. Light snow totaling 5.8 inches fell at times…and holiday traffic was delayed at Stapleton International Airport for several hours. Eight daily temperature records were set at the time. The all-time record low maximum temperature for the month of 8 degrees below zero on the 21st still stands today.

Boulder received 18 to 24 inches of snow. Two feet of snow buried Parker and Sedalia to the south of Denver. Weather conditions during the storm were brutal. Visibility at Stapleton International Airport was reduced to 1/4 mile or less for 17 consecutive hours. Sustained winds of 25 mph or more persisted for 15 consecutive hours. Gusts over 40 mph were recorded during 12 different hours. The highest recorded wind gust was 51 mph. The howling winds blew snow into drifts 4 to 8 feet high…paralyzing all modes of transportation. All highways leading out of Denver were closed. Stapleton International Airport was closed for 33 hours and operated on only a limited schedule for days afterward. Thousands of travelers were stranded and failed to reach their destinations in time for Christmas. Many wayward commuters and shoppers were forced to take refuge in shopping malls… Which remained open when workers themselves became stranded. Mall restaurants served food to the refugees. The storm prevented most people in the area from spending Christmas Day with family and friends. In metro Denver…three people died as a direct result of the blizzard: a 60-year-old man died of hypothermia on his screened in back porch; a 66 year old man froze to death after falling into a drift a few feet from his home; a 34- year-old man froze to death just east of Denver after abandoning his 4-wheel drive vehicle which became stuck in the snow. With the heavy snow and wind chill temperatures of 20 to 30 degrees below zero…there were many injuries from frostbite and falls. Damage from the blizzard was varied and widespread. A number of roofs collapsed under the weight of the heavy snow; greenhouses received the greatest damage when the heavy snow shattered glass roofs… Allowing cold air to freeze the tender plants inside. Total damage to greenhouses and plants alone was estimated at 5 million dollars. The strong winds with the storm damaged many fences and caused numerous power outages. Last minute Christmas shoppers were literally left out in the cold and snow…as the storm made travel increasingly difficult during the day. Merchants lost significant income from the last shopping day before Christmas. Overall…businesses lost an estimated 500 million dollars due to the blizzard. In metro Denver…seven million dollars were spent for snow removal…three million dollars in the city of Denver alone. This expenditure did not prevent a subsequent snow removal controversy. Once the major streets were made passable…cold late December and January temperatures prevented much melting. Icy and snowpacked side streets and parking lots became rutted… Making travel around metro Denver difficult for nearly a month after the storm. In fact…snow cover of an inch or more lasted for 48 consecutive days after the storm… Through February 9…1983. This is the third longest period of snow cover on record in the city. The period would have been longer…but no significant snow fell for more than 2 months after the storm.
In 2016…damaging high winds developed in and near the Front Range Foothills late Christmas morning and continued into the evening. Peak wind gusts in the Front Range Foothills reached 110 mph. In general…wind gusts ranged from 60 to 97 mph. In the Denver area…an estimated fifty thousand Xcel Energy customers lost power at some point…with most of the outages occurring west of Interstate 25. The outages were the result of downed trees and branches which struck power lines.

Heavy snowfall ranged from 1 to 2 1/2 feet in the foothills and from 6 to 18 inches across the city. Another slow moving storm system centered over the Texas panhandle produced deep upslope flow over the high plains and against the Front Range mountains.

The two storms cost the airport 4.6 million dollars in loss concession revenues. United Airlines reported lost revenue of over 25 million dollars from the two storms…while Frontier Airlines lost an estimated 12.1 million dollars.
