... Today in Metro Denver weather history...
2-17 in 1939... more than 2 weeks of unseasonably warm weather
made the month the 3rd warmest on record. Seven daily
temperature records were set... including the all time
record high temperature for the month of 79 degrees on
the 5th. Daytime highs were balmy with 14 days in the
60's and 70's. Low temperatures dipped to freezing or
below on only 5 days. The period was dry with only a
trace of snow on the 12th.
3-15 in 1972... a protracted cold spell held an icy grip on Metro
Denver when maximum temperatures never reached above
freezing for 10 consecutive days from the 3rd through
the 12th and minimum temperatures dipped below zero on
eleven consecutive days from the 5th through the 15th.
Daily low temperature records were set with 15 degrees
below zero on the 5th... 17 degrees below zero on the 6th...
and 18 degrees below zero on the 10th. Daily record low
maximum readings were set with 3 degrees on the 6th and
6 degrees on the 9th. The very cold temperatures were
caused by 3 to 5 inches of snow cover and a Canadian air
8-10 in 1985 a slow moving storm dumped 10 to 20 inches of snow
over the northeast plains... closing schools and businesses
in many areas along the Front Range north of Denver. At
Stapleton International Airport... snowfall totaled 9.9 inches
with a maximum snow depth of 7 inches on the ground. North
winds gusted to 24 mph. The snow caused long air traffic
delays at Stapleton International Airport on the 9th.
In 1997... persistent light to moderate snowfall combined
with strong and gusty northerly winds to produce much
blowing and drifting snow across Metro Denver. The
hardest hit areas were south of Denver where north winds
at speeds of 20 to 35 mph with gusts to 45 mph caused near
whiteout conditions. The strong winds produced drifts
2 to 4 feet deep and dropped wind chill temperatures
well below zero. Sections of both I-25 and I-70 and other
roads were closed as travel became impossible due to
blowing snow. Numerous traffic accidents were reported and
a handful of people were stranded during the snowstorm.
Snowfall totals included: 22 inches at Conifer... 13 inches
at Castle Rock... 12 inches at Parker... and 8 inches in
southeast Aurora. Snowfall totaled 5.5 inches at the
site of the former Stapleton International Airport.
North winds gusted to 36 mph at Denver International
Airport on the 10th.
8-12 in 1932... the second longest sub-zero period on record in
Denver occurred. The temperature fell below zero shortly
after 1:00 PM on the 8th and remained below zero for 92
hours until 9:00 am on the 12th. The lowest temperature
recorded during this period was 13 degrees below zero on
both the 9th and 11th. That temperature on the 11th was
a record low for the date. High temperatures of 4 on the
8th... 5 below zero on the 9th... 1 below zero on the 10th...
and 6 below zero on the 11th were record low maximum
temperatures for those dates. Light north winds at 5 to
10 mph were accompanied by occasional light snow... which
totaled only 2.2 inches.
9-13 in 1961... cold Arctic air produced a protracted cold period.
The temperature plunged to 16 degrees below zero on the
10th... establishing a new record for the date and the
coldest reading since 25 degrees below zero on February 1...
1951. Low temperatures dipped below zero on 5 consecutive
days with 9 degrees below zero on the 9th... 16 below on the
10th... 10 below on the 11th... and 12 below on both the 12th
and 13th. High temperatures reached only 3 degrees on the
10th and 6 degrees on the 11th.
10 in 1953... snowfall totaled 3.8 inches at Stapleton Airport
where northeast winds were sustained at speeds to 47 mph
and gusted to 60 mph behind a cold front.
In 1969... sustained winds of 30 mph with gusts to 55 mph in
downtown Boulder caused minor damage. Northwest winds
gusted to 39 mph at Stapleton International Airport.
In 1980... winds to 60 mph whistled through Boulder.
In 1987... strong winds in the foothills spread over northern
portions of Metro Denver. Wind gusts of 60 to 75 mph were
common in Boulder and southwestern Weld counties. However...
the highest reported wind gust... 94 mph... occurred near
Rollinsville. A northwest wind gust to 36 mph was recorded
at Stapleton International Airport.
10-11 in 1933... downslope winds produced warm temperatures... resulting
in record high minimums of 46 degrees on the 10th and 44
degrees on the 11th. High temperatures of 66 degrees on the
10th and 62 degrees on the 11th were not records. Southwest
winds were sustained to 16 mph on the 10th.
In 1939... high temperatures of 70 degrees on the 10th and 74
degrees on the 11th were record maximums for the dates.
The low temperatures of 39 degrees on the 10th and 41
degrees on the 11th were not records.
In 1948... high winds in Boulder and Louisville caused 1750
dollars in damage. Wind gusts in excess of 70 mph were
reported at Valmont and Boulder Airport. Chinook wind
gusts to 60 mph briefly reduced the visibility to 1/4 mile
in blowing dust at Stapleton Airport.
In 1989... the season's greatest snowfall to date hit Metro
Denver with 6 to 12 inches of snow. Flight delays at
Stapleton International Airport reached 2 hours. Multiple
wrecks snarled traffic on I-25 both north and south of the
city. Snowfall totaled 7.0 inches at Stapleton
International Airport where north winds gusted to 25 mph
on the 10th.
