...Today in metro Denver weather history...
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
18-24 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.
22-23 In 1982...wind gusts up to 101 mph were clocked at Wondervu.
Wind gusts of 60 to 80 mph were common along the Front
Range foothills from Boulder north.
22-26 In 1948...the longest period of snowfall on record (92 hours
and 3 minutes) occurred in downtown Denver where a total of
13.6 inches of snow fell. At Stapleton Airport...19.0 inches
of snow fell...making it the heaviest snow in January and the
5th heaviest snow of record at that time. North winds were
sustained to a velocity of 23 mph on the 25th...but generally
the winds were light throughout the storm. The snow
disrupted traffic...but street clearing was begun soon after
it became apparent that the snow would be heavy. Over the
5 days...temperatures ranged from a high of 48 degrees on
the 22nd to a low of 1 degree on the 26th. Most readings
were in the teens and 20`s during the storm.
23 In 1872...a brisk northerly wind set in about noon...blew
almost a gale about 6:00 PM...and continued brisk until
night. A light snow commenced during the late afternoon
and continued all night.
In 1886...northwest winds were sustained to 40 mph in the city
around sunrise. A cold wave accompanied the strong winds.
In 1897...a vigorous cold front produced northeast winds
sustained to 45 mph with gusts to 50 mph. Temperatures
plunged from a high of 59 degrees to a low of 11 degrees
in the evening. The very cold temperatures persisted
through the 28th.
In 1934...the date marked the last day of the longest period
of consecutive days without measurable precipitation in the
city. The 52 day period began on December 3...1933.
In 1988...one of the strongest windstorms in several years
pounded the Front Range foothills from Colorado Springs
north to the Wyoming border. The highest wind gust at
lower elevations was 105 mph recorded at Table Mesa in
Boulder. Other sections of Boulder recorded wind gusts of
80 to 90 mph. In Boulder...the high winds broke windows and
damaged power lines and transformers. Power outages were
widespread and traffic lights were downed. The winds blew
down a partially constructed viaduct in east Boulder. Nine
unanchored concrete girders...each weighing 45 tons...were
blown off their supports. Cars were blown off I-70 near
Morrison...and a tractor trailer and a mobile home were
knocked over. In Lakewood...an electric company crewman was
burned while replacing a power line. Wind gusts to 92 mph
were clocked at Jefferson County Airport in Broomfield
before the site anemometer was blown down by the wind.
The strong winds spread over all the metro area with a
northwest wind gust to 52 mph recorded at Stapleton
In 1992...high winds buffeted the eastern foothills. A wind
gust to 63 mph was recorded at Rocky Flats northwest of
Denver. West winds gusted to 40 mph at Stapleton
In 2002...low level upslope flow combined with an upper level
jet stream created bands of heavy snow over portions of
the Front Range foothills and metro Denver. The areas
hardest hit were the foothills of Jefferson and Douglas
counties and the I-25 corridor from the southern suburbs
of Denver to around Castle Rock. Snow totals included:
9 inches at Intercanyon...Roxborough State Park...and near
Sedalia; 8.5 inches atop Crow Hill and near Tiny Town;
8 inches at Ken Caryl and near Castle Rock; 7 inches in
Lakewood; 6.5 inches at Littleton; and 6 inches in Castle
Rock. Only 3.6 inches of snow were measured at the site
of the former Stapleton International Airport.
23-24 In 1921...heavy snowfall in downtown Denver totaled 8.0
inches overnight. Northwest winds were sustained to
22 mph with gusts to 25 mph on the 24th.
