...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
16-17 In 1886...a brief cold spell resulted in two temperature
records. High temperatures of zero degrees on the 16th
and 2 degrees below zero on the 17th were both record
low maximums for the dates. Low temperatures of
8 degrees below zero on the 16th and 16 degrees below
zero on the 17th were not records.
In 1930...temperatures plunging well below zero resulted
in two records. Low temperatures of 19 degrees below
zero on the 16th and 20 degrees below zero on the 17th
were record low temperatures for the dates. High
temperatures were 4 degrees on the 16th and 15 degrees
on the 17th. Light snowfall totaled 4.0 inches. North
winds were sustained to 18 mph on the 16th.
In 1964...high winds struck the eastern foothills. Gale
velocity winds were recorded in Boulder with gusts to 83

Roofs...walls...and parts of buildings were blown away at
various locations. Power poles and trees were blown over.

This was the only measurable snow of the month. North
winds were sustained to 20 mph on the 16th.
In 2011...very strong winds associated with an upper level
jetstream over Colorado produced blizzard conditions in
the mountains above timberline. Peak wind gusts
included: 99 mph atop Loveland Pass...94 mph...2 miles
southwest of Mary Jane...80 mph atop Berthoud Pass and
79 mph atop Niwot Ridge. Storm totals in the ski areas
west of Denver ranged from 8 to 14 inches.
17 In 1872...light snow fell during the morning and continued
into the afternoon until 3:30 PM. The sky commenced to
clear a little before 2:00 PM...but snow fell thickly for
at least half an hour even though the sky was perfectly
clear overhead. Melted snow totaled 0.33 inches.
In 1888...northwest winds were sustained to 46 mph in the city.
In 1905...intermittent rain...unusual in January...occurred
during the day. The rain changed to snow during the late

Precipitation totaled 0.62 inch. The temperature ranged
from a high of 44 degrees to a low of 32 degrees.
In 1950...wind gusts to 62 mph caused some blowing dust at
In 1982...one of the worst wind storms in many years hit the
Front Range foothills. The strongest winds occurred in
Boulder where at 2:30 AM a wind gust to 147 mph was recorded
at the National Center for Atmospheric Research...on the mesa
in southwest Boulder. At this location 20 wind gusts over
120 mph were clocked between 1:00 AM and 9:00 AM. An
estimated 40 percent of all buildings in Boulder received
at least minor wind damage. About 50 homes were damaged
enough to be uninhabitable. At least 15 homes in the Table
Mesa area of Boulder lost roofs. Twenty small airplanes
were destroyed at the Boulder airport. Utility poles were
snapped in two...and about one-seventh of the buildings in
the area were without power. Insured damage totaled 20
million dollars making the wind storm the most costly
on record in Colorado at the time.
In 1989...high winds were recorded along the eastern foothills
with gusts to 90 mph recorded at Rollinsville. North of
Denver on I-25...the wind injured two men when their tractor
trailer was blown off the road and rolled. West winds
gusted to 48 mph at Stapleton International Airport.
In 1990...an intense but localized snow storm caught many
people by surprise when it dumped 3 to 6 inches of snow
during a 3-hour period across portions of Boulder County.
The storm swath approximately 20 to 30 miles wide stretched
northeast from Boulder to just east of Longmont. Only
light snow fell over the remainder of metro Denver with
