January 29 to February 4 – This Week in Denver Weather History
You just never know what you are going to get with the weather in Denver and we see that in our look back at the Denver weather history books. From cold and snow to damaging winds and spring-like temperatures, we can and do see it all.
From the National Weather Service:
26-1
In 1888…a protracted warm spell lasted a week. Maximum temperatures ranged from 62 degrees on the 29th to an all time record high for the month of 76 degrees on the 27th.

27-31
In 1951…a major storm dumped 10.1 inches of snowfall at Stapleton Airport. Most of the snow…8.3 inches…fell on the 29th. Cold arctic air accompanied the snow. Several temperature records were set…including record low maximum temperatures of 4 on the 28th and 4 below zero on the 29th and record low temperatures of 12 below zero on the 29th and 24 below zero on the 31st. Temperatures were below zero for 45 consecutive hours.
28-29
In 1956…snowfall totaled 5.5 inches at Stapleton Airport where east winds gusted to 32 mph on the 28th.
In 1972…cold west winds buffeted Boulder. A wind gust to 92 mph was recorded at the National Bureau of Standards…while a gust to 76 mph was measured in downtown Boulder. Two mobile homes were overturned in Boulder. Other damage was minor. Northwest winds gusted to 40 mph at Stapleton International Airport on the 28th.
In 1987…strong winds buffeted the Front Range foothills and spread east over the plains. The highest wind recorded was 99 mph on the 29th at both the National Center for Atmospheric Research in Boulder and the Rocky Flats plant south of Boulder. Wind gusts in excess of 80 mph were common. A northwest wind gust to 54 mph was recorded at Stapleton International Airport on the 28th with a gust to 41 mph on the 29th. Planes were damaged at both the Boulder and Jefferson County Airports. Hangars were also damaged at Jefferson County Airport. Many windows were broken…signs toppled…and trees downed. A brick wall was blown onto parked cars in Lakewood. A couple of houses in Lakewood were unroofed…while falling trees damaged others. Two people were injured by flying debris in Lakewood and Golden. Total insured damage along the Front Range was 10 million dollars making the wind storm the second most costly on record in Colorado at the time.
In 1995…deepening upslope winds along the eastern foothills on the 28th gave way to periods of heavy snow during the night and early morning hours of the 29th. Snow fell to a depth of 8 inches in both Golden and Boulder with up to a foot in the foothills. Only 1.9 inches of snow fell at Stapleton International Airport…where east winds gusted to 22 mph on the 28th.

Snowfall totaled 6.0 inches at the site of the former Stapleton International Airport.
28-30
In 1887…winds were strong and gusty for three days in the city. West and northwest winds were sustained to 56 mph on both the 28th and 29th and to 44 mph on the 30th. Temperatures warmed to a high of 57 degrees on the 29th.
29

NASA’s newest climate and weather satellite captures stunning ‘blue marble’
When NASA launched the National Polar-orbiting Operational Environmental Satellite System Preparatory Project, or NPP, in October, it ushered in a new generation of climate and weather satellites. The school bus size spacecraft is now securely in polar orbit making 14 passes over the Earth each day.
The five main instruments are critical to enhancing not only short term weather forecasting but also in aiding long term climate modeling. NASA has performing an initial checkout of the craft and its instruments, a process which will take several more weeks before it begins its regular science mission.
This week NASA released an astounding ‘blue marble’ image captured by its Visible Infrared Imaging Radiometer Suite (VIIRS). The image is a composite from multiple orbits of the spacecraft on January 4, 2012 showing much of North and Central America.

January 22 to January 28 – This Week in Denver Weather History
Protracted cold spells, damaging and injuring winds and heavy snowfall mark our look back at this week in Denver weather history.
From the National Weather Service:
15-23
In 1962…a protracted cold spell kept metro Denver in the deep freeze for more than a week. From the 15th thru the 23rd…low temperatures were zero or below for 9 consecutive days…but a daily record low was set only on the 22nd when the temperature dipped to 14 degrees below zero. A record low maximum for the date was also set on the 22nd when the temperature climbed to only 11 degrees. The coldest high temperature was 3 degrees above zero on the 21st…which did not break the record. The protracted cold was broken for only a few hours on the afternoon of the 20th when Chinook winds warmed the temperature to a high of 38 degrees before another surge of cold arctic air plunged temperatures back into the deep freeze that evening. The severe cold caused much damage to water systems. A woman was frozen to death at Morrison. There were other deaths attributable to the weather…including traffic deaths and heart attacks from overexertion.
18-24
In 2005…a week of mid-winter unseasonably warm weather pushed high temperatures into the 60’s or more on all but one day. During the period…the highest temperature of 70 degrees on the 20th was a new record maximum for the date. Low temperatures remained above freezing on 4 of the days.
20-22
In 1937…a second incursion of cold arctic in less than two weeks kept temperatures in the deep freeze for three days… Even though only one temperature record was set during the period. Temperatures were below zero for an estimated 53 consecutive hours. The below zero period would have been longer had the temperatures on the 20th not climbed to a high of 1 degree after a low of 8 degrees below zero. On the 21st…the high temperature of 1 degree below zero was a record low maximum for the date. Low readings on both the 21st and 22nd were 9 degrees below zero.
In 1971…high winds raked Boulder. Wind gusts to 77 mph were recorded at the National Center for Atmospheric Research. Winds gusted to 83 mph in south Boulder and to 68 mph in downtown Boulder. Minor personal injuries occurred…and reported damage to structures totaled 15 thousand dollars. On the 21st…northwest winds gusted to 44 mph at Stapleton International Airport. The Chinook winds warmed the temperature to a high of 69 degrees on the 20th…which equaled the record for the date.
In 1993…sporadic high winds along the east slopes of the Front Range during the early morning hours of the 20th moved onto the foothills and plains by the 22nd. Wind gusts of 55 to 65 mph were common. Some significant wind reports included 82 mph at Rollinsville and atop Squaw Mountain west of Denver…and 75 mph on Rocky Flats. At Stapleton International Airport…west winds gusted to 35 mph on the 20th…44 mph on the 21st…and 55 mph on the 22nd.
21-22
In 1972…wind gusts to 74 mph were recorded at the National Bureau of Standards in Boulder…while in downtown Boulder wind gusts to 56 mph were measured. The strong winds overturned a plane at the Arapahoe County airport. A motorcyclist died of injuries when he was blown off a Boulder County road. Northwest winds gusted to 39 mph at Stapleton International Airport on the 21st.
In 1999…heavy snow developed across portions of metro Denver and in the foothills. Snowfall totals included: 8 inches in Golden Gate Canyon…Intercanyon…Rollinsville… And Parker; 7 inches at Aspen Springs…Gross Reservoir… Pine Junction…and 5 miles south of Sedalia; 6 inches at Highlands Ranch; and 5 inches at Eaglecrest…Eldorado Springs…and Louisville. Snowfall totaled 2.6 inches at the site of the former Stapleton International Airport. On the 21st…north-northwest winds gusted to 31 mph at Denver International Airport.
22
In 1899…a cold front produced northeast sustained winds to 50 mph with gusts to 60 mph in the city.
In 1951…a heavy windstorm struck Boulder. Minor damage was reported. Strong post-frontal east winds gusted to 45 mph at Stapleton Airport.
In 1990…strong winds of 50 to 90 mph buffeted the foothills. No significant damage was reported. West winds gusted to 37 mph at Stapleton International Airport.
In 1992…strong winds raked the eastern foothills with a wind gust to 58 mph recorded at Rocky Flats just northwest of Denver. West winds gusted to only 25 mph at Stapleton International Airport.
In 2003…only a trace of snow fell at the site of the former Stapleton International Airport. This along with a trace of snow on the 1st was the only snow of the month…which equaled the record for the least snowiest January first set in 1934.

ThorntonWeather.com News to participate in Internet ‘blackout’ on January 18
Senator Patrick Leahy (D-VT) is sponsoring PIPA in the Senate and Congressman Lamar Smith (R-TX) is carrying SOPA in the House of Representatives. The bills are backed by Hollywood and big media ostensibly as a way to stop online piracy and protect copyrights. They are however bad ideas that could lead to the censorship of websites like ThorntonWeather.com.
These ineffective and shortsighted bills would place undue burdens on websites and Internet providers. Any company with an intellectual copyright claim could for example force Google to remove links to an accused site, prevent credit card companies from processing payments to the accused site, and much more. This could all be done without any legal proceedings at all.
ThorntonWeather.com takes great care to respect and honor other’s property in written, audio or visual form and we are proud of our efforts to never take liberty with someone else’s hard work. However, under SOPA / PIPA, our site could be brought down simply if someone posted a comment that contained copyrighted text or linked to a site that hosted copyrighted material.
This simply is unacceptable. ThorntonWeather.com will be joining other sites like Wikipedia, Tucows, and Reddit in the blackout to take place tomorrow.
Please watch the video below for more information and contact your Senators and Congressman and urge them to vote against SOPA / PIPA. You can also learn more about the dangers of SOPA / PIPA via this infographic and at the links below the video.

January 15 to January 21 – This Week in Denver Weather History
January’s reputation of being dry and windy is evidenced in our look back at this week in Denver weather history. While there are some notable events involving snow, high winds have been the most frequent event worthy of mention.
From the National Weather Service:
13-16
In 1888…a cold air mass settled over the city and caused temperatures to plunge well below zero on four consecutive days…but only one temperature record was set. Minimum temperatures dipped to 4 degrees below zero on the 13th… 19 degrees below zero on the 14th…20 degrees below zero on the 15th…and 11 degrees below zero on the 16th.

In 1992…snow spread from the mountains across metro Denver. The heaviest snow was across the northern portion of the area where 7 inches fell at Thornton. At Stapleton International Airport…only 3.4 inches of snowfall were recorded and northeast winds gusting to 37 mph caused some blowing snow on the 14th.
In 1999…high winds howled across metro Denver. In Commerce City…strong winds toppled 3 utility poles resulting in a power outage to 600 homes. High wind reports included: 108 mph at Wondervu…80 mph at the Hiwan Golf Course in Evergreen…76 mph at Aspen Springs…75 mph at the Jefferson County Airport near Broomfield…74 mph in Boulder…and 70 mph at Georgetown. West to northwest winds gusted to 48 mph…the highest wind gust of the month…and warmed the temperature to a high of 60 degrees at Denver International Airport on the 15th.
14-21
In 1930…a protracted cold spell occurred when low temperatures plunged below zero on 8 consecutive days.

High temperatures during the period ranged from 18 on the 18th to zero on the 20th. Two degrees on the 15th was a record low maximum temperature for the date.
15
In 1875…the wind backed from the southwest to the northeast before noon. The temperature fell 48 degrees in one hour… From a high of 52 degrees to only 4 degrees between 11:30 am and 12:30 pm…as cold arctic air surged back over the city.

January 8 to January 14 – This Week in Denver Weather History
January in Colorado is known for two main weather conditions – cold and wind. Our look back at this week in Denver weather history shows why this reputation is well earned.
From the National Weather Service:
7-8
In 1911…gale force winds occurred in Boulder causing minor injuries.
In 1937…cold arctic air plunged temperatures below zero for an estimated 56 consecutive hours. Two temperature records were set. High temperatures of 8 degrees below zero on the 7th and 3 degrees on the 8th were record low maximum readings for those dates. Low temperatures plunged to 12 degrees below zero on the 7th and 11 degrees below zero on the 8th. Snowfall was 1.4 inches in downtown Denver.
In 1969…a violent evening windstorm struck Boulder and the adjacent foothills. A wind gust to 130 mph was recorded at the National Center for Atmospheric Research. Winds reached 96 mph in downtown Boulder. The Boulder airport wind recorder was blown away after measuring a wind gust to 80 mph. The windstorm caused over one million dollars in damage and one fatality in Boulder. About 25 homes in south Boulder had roofs blown off or were severely damaged. Roofs were blown off buildings housing scientific laboratories and offices of the Environmental Science Services Administration…now NOAA…in Boulder…and installations of several scientific measuring sites near Boulder received heavy damage. Grass fires driven by the high winds endangered many areas…but were controlled by volunteer firemen. One man died from injuries received when he was blown from a fire truck. One man was killed and another injured when the truck camper in which they were riding was blown off I-25 about 10 miles north of Denver. In the same area a mobile home and a truck trailer were blown off the highway and demolished. At least 20 people in the Boulder area received light to serious injuries from flying debris or from being blown into obstructions. Power lines and trees were downed over a wide area. Damage was relatively light in the city of Denver…where northwest winds gusted to 62 mph at Stapleton International Airport on the 8th. Many windows were broken in Arvada…Englewood…and Littleton. A 27-year-old fire lookout tower on Squaw Mountain…west of Denver…was blown away…and several radio relay towers at that location were toppled. Trucks were overturned near Georgetown. Mobile homes were overturned in several areas with occupants receiving injuries in some cases. The strong Chinook winds also brought warm weather. The maximum temperature of 69 degrees on the 7th broke the old record of 65 degrees set in 1948. The temperature also reached 65 degrees on the 8th…but was not a record.
In 1992…an intense blizzard buried eastern parts of metro Denver. At times snow fell at rates of 2 to 3 inches an hour. Winds increased from the north at speeds of 25 to 45 mph. Drifts of 4 to 8 feet were common. I-70 was closed east of Denver…and I-25 was closed from Denver south. Snowfall totals ranged from a couple of inches in the foothills west of Denver to as much as 2 feet on the east side of metro Denver. The heaviest snow fell on the 7th in a band from the northern suburbs of Westminster and Thornton through Aurora and east Denver to southeast of Parker. Snowfall totals included: 22 inches in southeast Aurora…14.8 inches at Stapleton International Airport…13 inches in Northglenn…10 inches in Parker…and 9 inches in Westminster. The 14.5 inches of snowfall measured on the 7th into the 8th is the greatest 24 hour snowfall ever recorded in the city during the month of January. North winds gusting to 46 mph caused much blowing snow at Stapleton International Airport.
In 2000…high winds developed in and near the Front Range foothills. The strongest winds were generally confined to foothills areas north of I-70. A wind gust to 76 mph was reported in Golden Gate Canyon. West winds gusted to 37 mph at Denver International Airport on the 8th.
7-10
In 1962…a major winter storm dumped 13.5 inches of snow on metro Denver. A foot of the snow fell on the 8th when northeast winds gusted to 30 mph. The storm was followed by an intense blast of very cold arctic air. Minimum temperature readings of 24 degrees below zero occurred on both the 9th and 10th. The temperature never reached above zero on the 9th when a maximum reading of 1 degree below zero was recorded. Temperatures were below zero for 37 consecutive hours.
8
In 1912…northwest winds were sustained to 40 mph with gusts to 45 mph in downtown Denver.
In 1971…wind gusts to 52 mph were recorded in downtown Boulder. Northwest winds gusted to 28 mph at Stapleton International Airport.
In 1990…high winds gusting from 50 to 90 mph along the Front Range produced much damage from blowing dust and gravel throughout the day. Wind gusts to 92 mph were recorded in the Table Mesa area of southwest Boulder. The winds caused sporadic power outages. Clouds of dust and gravel whipped by 70 to 90 mph gusts blinded commuters on the Denver-Boulder Turnpike near Broomfield during the morning rush hour. Flying gravel shattered windows on 50 vehicles parked near a Boulder high school. High winds were also blamed for partially dismantling a house under construction in Boulder…as well as toppling a number of fences…billboards…signs…and power poles. The strong cross-winds jack-knifed and overturned semi-tractor trailers on I-70 near Golden and just south of Boulder on State Highway 93. Several county airports were closed due to strong winds and blowing dust reducing visibilities. Wind delays up to 30 minutes occurred at Stapleton International Airport where west winds gusted to 48 mph. Eighty mph winds in Georgetown…Empire…and Idaho Springs were blamed for power and telephone outages. Windows were blown out of a sheriff’s car along I-70 east of Georgetown. The strong Chinook winds warmed the temperature to a high of 60 degrees in Denver.
In 2007…strong winds associated with an intense upper level jet…and a very strong surface pressure gradient…developed in and near the Front Range foothills. Peak wind gusts ranged from 77 mph to 115 mph. The strong winds coupled with freshly fallen snow resulted in whiteout conditions and several highway closures due to blowing and drifting snow. Road closures included: State Highway 93 between Golden and Boulder; State Highway 128 from Wadsworth Boulevard to State Highway 93; U.S. Highway 36…the Denver Boulder Turnpike from Broomfield to South Boulder Road; and State Highway 74 near Evergreen…between County Road 65 and Lewis Ridge Road. More than 100 people were stranded in their cars between Golden and Boulder as blowing and drifting snow made the highway impassable. Snow drifts along State Highway 93 were over 6 feet in depth. As a result… The American Red Cross opened a shelter at Arvada West High School for the stranded commuters. Up to twenty cars were also abandoned along the Diagonal Highway…between Boulder and Longmont. Thirty vehicles were stranded along State Highway 128. The high winds also caused intermittent power outages in Boulder. West winds gusted to 40 mph at Denver International Airport
