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

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.

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

winds on the 31st and 1st continued through the 8th.

degrees on the 2nd to 76 degrees on the 5th... which was
a new record high for that date.

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

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
