January 17 to January 23: This week in Denver weather history
Chinook winds in January oftentimes bring welcome warmth to the Front Range. They can however be more of a curse than a blessing as at times they can reach hurricane strength and do extensive damage. Looking back at this week in Denver weather history, we see many such occurrences.
From the National Weather Service:
14-21
In 1930…a protracted cold spell occurred when low temperatures plunged below zero on 8 consecutive days. The coldest low temperatures of 20 degrees below zero on the 17th and 19 degrees below zero on the 16th were record minimums for the dates. 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.
15-23
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.
16-17
In 1886…a brief cold spell resulted in two temperature records. High temperatures of zero degrees on the 16th and 2 degrees below zero on the 17th were both record low maximums for the dates. Low temperatures of 8 degrees below zero on the 16th and 16 degrees below zero on the 17th were not records.
In 1930…temperatures plunging well below zero resulted in two records. Low temperatures of 19 degrees below zero on the 16th and 20 degrees below zero on the 17th were record low temperatures for the dates. High temperatures were 4 degrees on the 16th and 15 degrees on the 17th. Light snowfall totaled 4.0 inches. North winds were sustained to 18 mph on the 16th.
In 1964…high winds struck the eastern foothills. Gale velocity winds were recorded in Boulder with gusts to 83 mph measured at Rocky Flats. Several airplanes were damaged at the Jefferson County Airport in Broomfield. Roofs…walls…and parts of buildings were blown away at various locations. Power poles and trees were blown over.
16-18
In 1943…light snowfall totaled 3.2 inches over the 3 days. This was the only measurable snow of the month. North winds were sustained to 20 mph on the 16th.
In 2011…very strong winds associated with an upper level jetstream over Colorado produced blizzard conditions in the mountains above timberline. Peak wind gusts included: 99 mph atop Loveland pass…94 mph… 2 miles southwest of Mary Jane…80 mph atop Berthoud Pass and 79 mph atop Niwot Ridge. Storm totals in the ski areas west of Denver ranged from 8 to 14 inches.
17
In 1872…light snow fell during the morning and continued into the afternoon until 3:30 pm. The sky commenced to clear a little before 2:00 pm…but snow fell thickly for at least half an hour even though the sky was perfectly clear overhead. Melted snow totaled 0.33 inches.
In 1888…northwest winds were sustained to 46 mph in the city.
In 1905…intermittent rain…unusual in January…occurred during the day. The rain changed to snow during the late evening…but ended before midnight. Snowfall was 2.0 inches. Precipitation totaled 0.62 inch. The temperature ranged from a high of 44 degrees to a low of 32 degrees.
In 1950…wind gusts to 62 mph caused some blowing dust at Stapleton Airport.
In 1982…one of the worst wind storms in many years hit the Front Range foothills. The strongest winds occurred in Boulder where at 2:30 am a wind gust to 147 mph was recorded at the National Center for Atmospheric Research…on the mesa in southwest Boulder. At this location 20 wind gusts over 120 mph were clocked between 1:00 am and 9:00 am. An estimated 40 percent of all buildings in Boulder received at least minor wind damage. About 50 homes were damaged enough to be uninhabitable. At least 15 homes in the Table Mesa area of Boulder lost roofs. Twenty small airplanes were destroyed at the Boulder airport. Utility poles were snapped in two…and about one-seventh of the buildings in the area were without power. Insured damage totaled 20 million dollars making the wind storm the most costly on record in Colorado at the time.
In 1989…high winds were recorded along the eastern foothills with gusts to 90 mph recorded at Rollinsville. North of Denver on I-25…the wind injured two men when their tractor trailer was blown off the road and rolled. West winds gusted to 48 mph at Stapleton International Airport.
In 1990…an intense but localized snow storm caught many people by surprise when it dumped 3 to 6 inches of snow during a 3-hour period across portions of Boulder County. The storm swath approximately 20 to 30 miles wide stretched northeast from Boulder to just east of Longmont. Only light snow fell over the remainder of metro Denver with 0.2 inch of snowfall measured at Stapleton International Airport where northeast winds gusted to 30 mph.
In 1998…strong winds in the foothills spread over the plains mainly north of metro Denver. Winds gusted to 75 mph at Golden Gate Canyon. West winds gusted to 34 mph at Denver International Airport.
17-18
In 1974…rare overnight January rainfall totaled 0.12 inch on the 17th and 0.26 inch on the 18th when it was briefly mixed with snow.
In 2012…damaging winds developed in and near the Front Range. In Boulder…the high winds knocked down several trees… Power poles and electrical lines. Some of the fallen trees damaged homes and automobiles. A semi-trailer was blown on its side along State Highway 93 near Marshall. Peak wind gusts included: 104 mph in south Boulder; 98 mph…3 miles southwest of Pinecliffe; 95 mph…2 miles northwest of Rocky Flats; 92 mph…at State Highway 93 near Marshall; 87 mph at Berthoud Pass and in Boulder Canyon; 80 mph…5 miles west- northwest of Boulder; 83 mph at NCAR Mesa Lab; 78 mph…8 miles northeast of Four Corners; 79 mph at the National Wind Technology Center; 76 mph at Wondervu; 75 mph atop Loveland Pass and the NCAR foothills lab in Boulder; 74 mph at Blue Mountain…Boulder Municipal Airport… 1 mile northwest of Lyons; 73 mph…4 miles east-northeast of Nederland; 72 mph at the junction of State Highways 72 and 93; 62 mph in Superior; and 61 mph at Erie Municipal Airport. A peak wind gust of 38 mph from the northwest was observed at Denver International Airport.

Hurricane Alex becomes first January hurricane since 1938
From the National Hurricane Center:
Remarkably, Alex has undergone the transformation into a hurricane. It’s the first hurricane to form in the month of January since 1938, and the first hurricane to be present in this month since Alice of 1955. (Alice formed in late December 1954 and carried over into January 1955.) Alex’s maximum sustained winds are near 85 mph (140 km/h) with higher gusts – a Category 1 hurricane on the Saffir-Simpson Hurricane Wind Scale. Little change in strength through Friday is forecast.
At 1100 a.m. AST (1500 UTC), the center of Hurricane Alex was located about 490 miles south of Faial Island in the Central Azores, moving toward the north-northeast near 20 mph (31 km/h). A turn toward the north with an increase in forward speed is expected over the next day or two. On the forecast track, the center of Alex will move near or over portions of the Azores Friday morning.
The Azores Meteorological Service has issued a Hurricane Warning for the islands of Faial, Pico, Sao Jorge, Graciosa, and Terceira in the central Azores, and a Tropical Storm Warning for the islands of Sao Miguel and Santa Maria in the eastern Azores.
Tropical-storm-force winds are expected to begin over portions of the Azores tonight. Hurricane conditions are expected to spread over the central Azores by early Friday. Wind speeds atop and on the windward sides of hills and mountains are often up to 30 percent stronger than the near-surface winds indicated in this advisory, and in some elevated locations could be even greater.
Alex is expected to produce total rain accumulations of 3 to 5 inches over the Azores through Friday, with possible isolated maximum amounts of 7 inches. These rains could produce life-threatening flash floods and mudslides. A dangerous storm surge is expected to produce significant coastal flooding near and to the east of the center of Alex. Near the coast, the surge will be accompanied by large and destructive waves.

January 10 to January 16: This week in Denver weather history
January weather is like the weather of any other month in Denver in that you can see just about any type of condition possible. However, three conditions are dominant during the month – wind, snow and cold. All three make many appearances in our look back at this week in Denver weather history.
From the National Weather Service:
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.
8-10
In 1983…winds of 70 to 90 mph howled through Boulder. A wind gust to 100 mph was recorded on Fritz Peak near Rollinsville. A tree blown down by the wind damaged a house in eastern Boulder County. The strong winds developed behind a cold front late on the 8th and continued through the 10th. At Stapleton International Airport…west to northwest winds gusted to 49 mph on the 8th…to 45 mph on the 9th…and to 48 mph on the 10th.
9-10
In 1962…the low temperature plunged to 24 degrees below zero on both days.
In 1972…a west wind gust to 60 mph was recorded at Stapleton International Airport…while in Boulder a wind gust to 86 mph was recorded at the National Bureau of Standards. The roof of a house was blown off…and trees were blown down in Boulder. The high winds contributed to the damage from a building fire in Boulder.
In 2000…heavy snow and strong winds in the mountains spilled into the Front Range foothills. Ward…northwest of Boulder…received 9 inches of new snow. Wind gusts to 91 mph were measured in Golden Gate Canyon…with gusts to 77 mph at Loveland Ski Area and to 73 mph along State Highway 93 north of Golden. West winds gusted to 44 mph at Denver International Airport on the 9th.
In 2011…a winter storm brought moderate to heavy snowfall to areas in and near the Front Range foothills and Palmer Divide. Storm totals included: 13 inches…3 miles south of Golden; 11.5 inches near Eldorado Springs…10.5 inches… 2 miles southwest of Boulder; 10 inches…3 miles southwest of Roxbourough State Park; 9 inches at Genessee…8.5 inches in Arvada…4 miles south-southeast of Bennett and greenwood village…8 inches… 8 miles south of Elizabeth; 7 inches at Commerce City and 6.5 inches near Louisville and at Denver International Airport. Gusty winds produced snow drifts up to 2 feet deep over the Palmer Divide.
10
In 1893…strong west winds in Boulder and the adjacent foothills caused only minor damage.
In Denver…northwest winds were sustained to 48 mph with gusts as high as 60 mph. The Chinook winds warmed the temperature to a high of 64 degrees and a low of only 40 degrees…which was a record high minimum for the date.
In 1911…southwest Chinook winds sustained to 44 mph warmed the temperature to a high of 60 degrees.
In 1932…the first thunderstorm ever officially recorded in Denver during January occurred in the early morning. The assistant observer heard two prolonged peals of thunder between 4:20 am and 4:25 am. Another off-duty observer was awakened by the thunder. Other people reported both thunder and lightning. Light snow was falling at the time. Pellets of graupel or hail were reported from some parts of the city. Snowfall totaled only 1.8 inches. Northwest winds gusted to 30 mph.
In 1962…as the temperature dipped to a frigid 24 degrees below zero…setting a new record minimum for the date… The pressure adjusted to sea level reached the highest ever recorded in Denver…31.24 inches (1057.8 mb). The altimeter setting reached 30.70 inches…and the actual station pressure recorded was 25.260 inches.
In 1988…strong winds occurred throughout the day in and near the foothills. Peak gusts to 85 mph were recorded at Rollinsville…84 mph at Echo Lake…and 64 mph in Boulder.
In 1990…a third consecutive day of 50 to 85 mph wind gusts occurred in and along the eastern foothills. A 5 mile portion of the Denver-Boulder turnpike was closed after clouds of blowing dust and gravel caused several multicar accidents near Broomfield. One 59-year-old woman was killed and two others injured. A wind gust to 81 mph was recorded at the nearby Jefferson County Airport.
In Boulder…wind gusts to 85 mph were blamed for ripping off a portion of a roof on a house…as well as blowing out the large picture window. West winds gusted to 41 mph at Stapleton International Airport. The warm Chinook winds set a record high temperature of 71 degrees in Denver for the date.
In 1996…strong northwest winds developed behind a pacific cold front that moved rapidly across northeast Colorado. A peak wind gust to 64 mph was recorded at the Rocky Flats Environmental Test Facility in Jefferson County. North- northeast winds gusted to 38 mph at Denver International Airport.
10-11
In 1948…strong winds were reported in Boulder and Lakewood. Winds of 50 to 60 mph were reported at Valmont…just east of Boulder. Only minor damage was reported.
In 1980…strong winds of 60 to 95 mph howled across metro Denver…causing some brief power outages and some broken windows. A wind gust to 111 mph was recorded at Wondervu. Northwest winds gusted to 40 mph at Stapleton International Airport on the 10th.
In 1999…high winds gusting to 100 mph blasted the foothills. Peak wind gusts included: 100 mph at central city…98 mph at Wondervu…82 mph at Aspen Springs and Golden Gate Canyon… 81 mph at the NCAR Mesa Lab in Boulder and near Nederland… 78 mph atop Blue Mountain near Coal Creek Canyon…and 72 mph at the Rocky Flats Environmental Test Facility. West winds gusted to 38 mph and warmed the temperature to a high of 63 degrees at Denver International Airport on the 11th.
10-12
In 1997…heavy snow fell over the Front Range foothills. A foot of new snow was measured at Blackhawk with 7 inches recorded in Coal Creek Canyon. Only 3.3 inches of snow fell at the site of the former Stapleton International Airport. East-northeast winds gusted to 18 mph at Denver International Airport on the 11th.
10-13
In 1963…a arctic cold wave plunged temperatures well below zero across metro Denver. Temperatures were below zero for a total of 64 consecutive hours. Low temperatures reached 25 degrees below zero on both the 11th and 12th. The high temperature of 9 degrees below zero on the 11th was the coldest ever recorded at Stapleton Airport and equaled the record low maximum for the month first set on January 19…1883…in downtown Denver. The high temperature on the 12th reached only 1 degree below zero. On the 12th…an 18-year-old youth died of exposure from the extreme cold in Denver. There were many losses and damage to property from frozen water systems…stalled cars…and over-burdened heating systems. Light snow accompanied the arctic blast. At Stapleton Airport…2.3 inches of snow fell on the 10th and 11th.

We can’t blame El Niño for all the world’s weather problems
|
LIMA, Peru — As 2015 drew to a close, South America saw almost unprecedented flooding. More than 100,000 people were evacuated from their homes in Paraguay, northern Argentina and southern Brazil as a result of unseasonal torrential rain. International media widely attributed the freaky weather to El Niño. Yet the whole truth is probably more complex.… Continue reading We can’t blame El Niño for all the world’s weather problems |
