...Today in metro Denver weather history...
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
18-19 In 1980...a slow moving storm deposited 4 to 10 inches of
snow across metro Denver with the greatest amounts in the
foothills. Flights were delayed 30 to 40 minutes at
Stapleton International Airport where snowfall totaled
5.5 inches and north winds gusted to 22 mph.
In 1988...a blizzard produced strong winds and heavy snow
across eastern Colorado. Ten-foot drifts were common and
many roads were closed including I-70...I-76...and I-25.
In the Denver area...4.0 inches of snow fell at Stapleton
International Airport where north winds gusting to 40 mph
reduced the visibility to 1/2 mile at times.
18-20 In 1958...snowfall totaled 6.9 inches at Stapleton Airport
where east-northeast winds gusted to 26 mph on the 18th.
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.
19 In 1883...the low temperature dropped to 20 degrees below
zero...and the high temperature of only 9 degrees below
zero was the record low maximum for January...which
was equaled on January 11...1963.
In 1887...west winds sustained to 48 mph warmed the
temperature in the city to a high of 67 degrees...which
was the highest temperature of the month that year.
In 1890...northwest winds were sustained to 42 mph with
gusts to 45 mph in the city.
In 1903...northwest winds were sustained to 40 mph with an
extreme velocity of 44 mph.
In 1911...west chinook winds sustained to 42 mph warmed
the temperature to a high of 66 degrees.
In 1916...sleet (grains of ice) fell for 15 minutes. This
is a rare occurrence in Denver.
In 1990...7 to 10 inches of snow fell across metro Denver.
Strong winds...drifting snow...and poor visibility caused
the closure of I-70 from Denver east to the Kansas border.
However...at Stapleton International Airport north winds
gusted to only 17 mph. Several schools and businesses
were forced to close. Weather-related delays of up to
90 minutes hampered aircraft operations at Stapleton
International Airport where snowfall from the storm
totaled 7.5 inches.
In 2002...high winds occurred over portions of the northern
mountains and eastern foothills. Wind reports included:
74 mph at the National Center for Atmospheric Research
atop the mesa in Boulder and 71 mph at the Eldora Ski
Resort west of Boulder.
In 2003...a wind gust to 75 mph was recorded at the
National Wind Technology Center atop Rocky Flats
to the northwest of Denver. West winds gusted to
36 mph at Denver International Airport.
19-20 In 1935...snowfall of only 0.8 inch during the evening of
the 19th was the only measurable snowfall of the month.
The light snow developed behind an Arctic cold front as
temperatures plunged to a low of 13 degrees below zero
on the 20th. High temperature of only 2 degrees on the
20th was a record low maximum for the date. Northeast
winds were sustained to 16 mph on the 19th.
In 1986...chinook winds gusting to 39 mph at Stapleton
International Airport provided record breaking warmth.
The warmest temperature of the month...68 degrees on the
19th...was also a record high for the date. The low
temperature of 41 degrees on the 20th equaled the record
high minimum for the date.
In 1991...a strong cold front moved south across metro Denver.
Upslope conditions produced 3 to 6 inches of snow along the
Front Range with 5 inches in Westminster and 4 inches in
Thornton. Snowfall measured 4.9 inches at Stapleton
International Airport where north winds gusted to 31 mph.
