...Today in metro Denver weather history...
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.
31-8 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.
1-6 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
4-6 In 1986...10 inches of snow fell in Boulder...in the foothill
town of Wondervu southwest of Boulder...and at Evergreen
west of Denver. Snowfall totaled 2.4 inches at Stapleton
International Airport...where north winds gusted to 20 mph
on the 6th.
5-6 In 2003...heavy snow fell in the foothills. Snowfall totals
included: 17 inches at Genesee; 16 inches at Lookout
Mountain; 11 inches at Chief Hosa near Indian Hills...and
7 miles southwest of Boulder; 10.5 inches atop Gold Hill;
and 10 inches at Intercanyon and near Conifer. Only 2.2
inches of snowfall were measured in the city at the site
of the former Stapleton International Airport.
5-11 In 1978...the 5th marked the start of a record 7 consecutive
days of dense fog at Stapleton International Airport. The
heavy fog reduced the visibility to 1/4 mile or less for a
period of time on each of these days. Light snow and/or
freezing drizzle occurred on most days. Fog reducing
visibility to less than 7 miles was recorded at Stapleton
International Airport on 11 consecutive days through the
15th. During the period 5-14...the cold thick fog deposited
heavy rime ice up to 5 inches thick on power lines and poles
over a wide area of eastern Colorado...causing a major
electrical power outage disaster.
6 In 1899...the temperature dipped to a low of 22 degrees below
6-7 In 1929...5.0 inches of snow fell in downtown Denver behind
a Canadian cold front. Temperatures plunged...but no records
were set. Low readings dipped to 3 degrees below zero on
the 6th and 9 degrees below zero on the 7th. Highs climbed
to 5 degrees on the 6th and to only 1 degree below zero on
In 1933...post-frontal light snowfall totaled 3.0 inches over
downtown Denver. Northeast winds were sustained to 28 mph
with gusts to 32 mph on the 6th. The very cold air mass
plunged temperatures from a high of 60 degrees on the 5th
to lows of 10 degrees below zero on the 6th and 16 degrees
below on the 7th. High temperature of only 4 degrees below
zero on the 7th was a record low maximum for the date.
6-10 In 1933...3:00 PM on the 6th marked the start of a protracted
cold period through 8:00 AM on the 10th when the temperature
was below zero for 86 out of 88 hours. The cold period was
interrupted on the 8th at 9:00 AM when the temperature was
1 degree above zero and at 10:00 AM when the temperature was
8 degrees above zero. Four temperature records were set.
High temperatures of 4 degrees below zero on the 7th...8
degrees on the 8th...and 5 degrees below zero on the 9th were
record low maximums for those dates. The only record low
temperature record was 14 degrees below zero on the 10th.
The lowest temperature reached during the period was 16
degrees below zero on both the 7th and 8th...which were not
