all time record high for the month of 76 degrees on the
27th. Daily record high temperatures of 76... 69... and 71
occurred on the 27th... 28th... and 30th respectively.
Record high minimum temperatures of 47 and 34 occurred
on the 26th and 27th.
30-7 in 1985... a cold front on the 29th produced a protracted cold
spell as Arctic air remained entrenched across Metro Denver.
While the only daily temperature record set was a low
maximum reading of 2 degrees on February 3rd... minimum
temperatures plunged well below zero on 9 consecutive days.
The coldest readings were 15 degrees below zero on January
31st and 14 degrees below zero on February 5th.
31-1 in 1963... high winds struck Metro Denver. The strong
Chinook winds reached 101 mph in Littleton... 80 mph in
Denver... and 90 mph at Rocky Flats. Among the hardest hit
areas were Boulder where buildings under construction were
blown down... porches and roofs blown off buildings... and
power lines damaged. Damage totaled 100 thousand dollars
in Boulder alone. In other areas... utility lines were
damaged and many signs... antennas... and Road markers were
blown down. At Stapleton Airport... west winds gusted to
44 mph on the 31st and 66 mph on the 1st. The Chinook
winds warmed maximum temperatures to 65 degrees on the
31st and to 70 degrees on the 1st.
31-8 in 1963... warm weather that began with the strong Chinook
winds on the 31st and 1st continued through the 8th.
Maximum temperatures through the period ranged from 52
degrees on the 2nd to 76 degrees on the 5th... which was
a new record high for that date.
31-12 in 1899... a protracted cold spell lasted almost two weeks.
Low temperatures plunged below zero on all days but
February 9th with a reading of 6 degrees. The coldest
low temperature of 22 degrees below zero on February 6th
was a record low for the date. Low temperatures of 20
degrees below zero occurred on both February 11th and 12th...
but only the 11th remains as the record minimum for the
date. High temperature of only 5 degrees below zero on
February 11th was a record low maximum for the date. High
temperatures climbed to only zero degrees on both February
2nd and 3rd... but were not records. Intermittent light snow
or flurries fell during the period. The most snowfall... 2.0
inches... occurred on February 2nd.
1 in 1904... northwest winds were sustained to 51 mph with
gusts to 60 mph. The Chinook winds warmed the
temperature to a high of 55 degrees.
In 1907... west winds sustained to 42 mph warmed the
temperature to a high of 59 degrees.
In 1932... the temperature rose from a low of 8 degrees
at 7:00 am to the high of 58 degrees at 2:30 PM. The
biggest jump occurred from 16 degrees at 8:00 am to
42 degrees at 9:10 am.
In 1951... the lowest recorded temperature in February... 25
degrees below zero... occurred. The same temperature was
also reached on February 8... 1936.
In 1963... west-southwest winds gusted to 66 mph at Stapleton
Airport where the strong Chinook winds warmed the
temperature to a maximum of 70 degrees.
In 1970... snowfall of 0.3 inch contained only 0.01 inch of
melted snow. This was the only measurable snow and
precipitation for the month... making it the driest and
least snowiest February on record. Snowfall also was
only 0.3 inch on February 22-23... 1992... equaling the
least snowiest February.
In 1980... high winds occurred in the foothills. Wind gusts
to 75 mph were reported at Wondervu. Northwest winds
gusted to 32 mph at Stapleton International Airport.
In 1995... a short blast of early morning winds near the
foothills produced a gust to 64 mph at Rocky Flats in
northern Jefferson County. Winds gusting to 59 mph in
Lakewood downed a few tree branches in residential areas.
West winds gusted to 37 mph at Stapleton International
Airport where the warm winds kept the temperature from
falling below 43 degrees... setting a new record high
minimum for the date. The temperature climbed to a
non-record high of 63 degrees.
1-2 in 1934... light Chinook winds warmed temperatures to record
levels on both days. Record maximum temperatures
reached 73 degrees on the 1st and 74 degrees on the 2nd.
West winds were sustained to 18 mph on the 1st.
1-3 in 1996... cold Arctic air plunged temperatures below zero
for more than 35 consecutive hours from late on the 1st
until sunrise on the 3rd. The temperature warmed to only
1 degree below zero on the 2nd after a record low of
16 degrees below zero.
1-4 in 2011... a frigid Arctic airmass settled into Front Range
urban corridor. At Denver International Airport...
overnight low temperatures... from the 1st to the 3rd...
were 13 below zero... 17 below zero and zero respectively.
The icy temperatures caused pipes to crack and burst
following the freeze. In Loveland... firefighters
responded to more than a dozen Water Pipe breaks... most
in fire sprinkler systems at businesses... apartments and
assisted care facilities. At cu Earth science Library
in Boulder... more than 1000 books and several costumes
for an upcoming production were damaged. At the County
courts administration building in Jefferson County... a
steady stream of water from a crack on the 5th floor...
went unnoticed on the 3rd and flooded all the floors of
the administration Wing overnight. As a result... much of
the office equipment... furniture and carpet sustained
water damage. A burst sprinkler line caused minor
damage at the Platte valley medical center in Brighton.
The icy temperatures forced to closure of several school
districts as well.
1-5 in 1985... the most bitter cold spell of the winter season
brought sub-zero temperatures to Metro Denver. Daily low
temperature records were broken at Denver. The usual cold
weather problems struck including stalled vehicles... jammed
traffic lights... and frozen water and sewer lines. At
Stapleton International Airport... the high temperature
was only 2 degrees above zero on the 1st... setting a record
low maximum for the date. Low temperatures reached 13 below
zero on the 1st... 12 below on the third... and 14 below on the
1-6 in 1989... one of the century's worst doses of winter weather
ravaged the entire state. Bitterly frigid weather moved
into Metro Denver on the 1st as snow buried many sections
of the state. In Metro Denver where 3 to 6 inches of snow
fell... blowing snow and resultant poor visibilities caused
a 46-car pile-up on I-25 in the middle of the city on the
4th. During the period... 2 to 3 hour delays were common at
Stapleton International Airport where snowfall from the
storm totaled 4.3 inches and northeast winds gusted to 30
mph on the 1st. Intense cold accompanied the storm.
Temperatures in Denver stayed below zero continuously for
the best part of 3 days (3rd... 4th... 5th)... for a total of 69
hours. This is the fourth longest sub-zero period on
record. Wind chill temperatures reached 50 degrees below
zero. The Mercury dipped to 24 degrees below zero on the
5th... setting a record for the date. This was the city's
coldest temperature in over 26 years. Low temperatures
dipped below zero on 8 consecutive days (2nd-9th). High
temperature of 9 degrees below zero on the 4th was a record
low maximum for the date... as was the high of 5 degrees on
the 5th. Extensive damage occurred when pipes and water
lines froze and broke. Thousands of cars failed to start.
On the 3rd... a 57-year-Old Woman died of hypothermia in an
Arvada park. Eighteen High School students were treated
for hypothermia after a 2-hour ride through Jefferson
County in an unheated bus. At least 2 cases of frostbite
were reported; there were undoubtedly many more.
1-9 in 1883... a protracted cold period occurred when low
temperatures dipped below zero for 9 consecutive days.
Low temperatures ranged from 22 degrees below zero on
the 4th to 2 degrees below zero on the 1st and 6th. High
temperatures ranged from 10 below zero on the 3rd to
23 on the 9th. Several temperature records were set
that still stand today. Record lows of 18 below and
22 below zero occurred on the 3rd and 4th. Record low
maximum readings of 2 below and 10 below zero occurred on
the 2nd and 3rd. The high of only 10 below zero on the
3rd is the coldest maximum temperature ever recorded in
2 in 1890... west winds were sustained to 44 mph with an
extreme velocity of 45 mph. The Chinook winds warmed
the temperature to a high of 66 degrees.
In 1970... high winds caused scattered damage along the
foothills from Golden north. A garage in Boulder was
demolished. Broken windows and roof damage were reported
in Golden. Wind gusts from 60 to 100 mph were recorded in
In 1990... a narrow band of heavy snow fell in the foothills
southwest of Denver. Up to 6 inches piled up at Waterton
canyon with 5 inches around the town of Deermont... both
along the South Platte river in Jefferson County. Snowfall
was only 1.6 inches at Stapleton International Airport
where north winds gusted to 30 mph.
In 1995... the second morning in a row of strong winds raged
in the foothills and adjacent lower elevations. Winds
gusted between 70 and 85 mph in the foothills and 45 to
50 mph on the plains. A tree was blown onto high voltage
power lines in a west Denver suburb. The fence that the
wire landed on caught fire... but did no damage to the
surrounding structures. A southwest Denver man was
injured when a wind gust blew him and the front door he
was holding off a porch. West winds gusted to 45 mph at
Stapleton International Airport. The strongest winds
occurred in Georgetown where a gust to 100 mph overturned
a pick-up truck Camper on I-70. The driver sustained only
In 2001... high winds developed briefly in the Front Range
foothills. A spotter at Georgetown Lake measured a
peak wind gust to 90 mph.
In 2008... lightning struck a home in Englewood during an
electrically charged snowstorm. A gas meter at the home
was hit by lightning and burst into flames. The unusual
thunderstorm produced a combination of snow and graupel.
The graupel was up to one half inch in diameter. Total
snow accumulations ranged from 1 to 4 inches across the
southern Denver suburbs. Snowfall was only 0.6 inch at
the former Stapleton International Airport.
2-3 in 1894... 6.2 inches of heavy snowfall were measured over
downtown Denver. East winds gusted to 25 mph on the 2nd.
In 1999... a powerful Chinook windstorm struck the foothills
and adjacent plains. Several locations registered wind
gusts in excess of 100 mph... including: 127 mph atop
Sugarloaf Mountain... 120 mph at Lafayette... 119 mph at
Wondervu... 104 mph at Coal Creek... 103 mph at the Rocky
Flats environmental test facility and 100 mph in
Louisville. The damage associated with the windstorm was
extensive. Thirty 70-foot-tall power poles were damaged...
including several that supported high voltage lines
transmitting electricity directly from generating plants.
The combination of downed power poles... power lines... and
trees resulted in outages for about 10 thousand residents.
In Lafayette... power poles were sheared off for a mile
and a quarter. The power outages primarily affected
residents in Boulder... Broomfield... Lafayette... Louisville...
and Fort Lupton. In addition to the outages... high winds
ripped apart several roofs in Boulder... including the roof
of the Boulder County jail. At Jefferson County Airport...
several planes were overturned and some hangars damaged or
destroyed. Damage to the Airport alone was estimated at
100 thousand dollars. In southern Jefferson County...
localized ground blizzards reduced visibilities in blowing
snow to less than 20 feet along U.S. Highway 285... resulting
in several accidents. In Pine Junction a downed tree
damaged a nearby residence... when it crashed onto the roof.
In Bailey... a downed tree crushed a vehicle parked in the
resident's driveway. Total damage estimates for the
windstorm reached 3 million dollars... making it the fourth
costliest on record at the time in Colorado. Other peak
wind gusts include: 97 mph at Boulder... 93 mph at the
National center for atmospheric research Mesa lab in Boulder...
88 mph at Nederland... 86 mph at Aspen Springs... and 83 mph at
Blue Mountain near Coal Creek Canyon. West to northwest
winds gusted as high as 46 mph at Denver International
2-4 in 2012... a slow moving and powerful storm system brought heavy
snow to areas in and near the Front Range foothills and Palmer
Divide... with blizzard conditions over the northeast plains of
Colorado. In the Front Range foothills... the snow piled up to
over 4 feet in some areas. Across the Palmer Divide... the
combination of snow and gusty winds resulted in Road closures
with snow drifts ranging from 2 to 5 feet in depth. Northerly
winds 15 to 25 mph were common with gusts to 40 mph. Several
snowfall records were also set in Denver. At Denver
International Airport... 12.5 inches of snow feet on the 3rd
shattered the previous record of 7.5 inches for the date. It
also set a new daily record for the entire month of February.
A new 3-day record was also established for Denver. The 3-day
storm total from February 2nd to the 4th was 15.9 inches...
which broke the previous record of 14.1 inches in 1912.
Denver International Airport canceled more than six hundred
flights. In addition... snow and blowing snow produced near zero
visibilities... forcing officials to close the westbound lanes of
Interstate 70... between the Kansas state line and Denver... as
well as the eastbound lanes from Denver to Limon. Other Road
closures included State Highway 86... between Kiowa and I-70.
