...This week in metro Denver weather history...
7-12 In 1959...snow falling over a 5-day period totaled 20 to 30
inches just east of the mountains...while over the plains
blizzard conditions closed schools and blocked highways.
The second big storm in two weeks dumped 16.4 inches of
snowfall on Stapleton Airport with the most...11.6 inches...
occurring on the 8th. East winds gusted to 37 mph on the
9th. Temperatures dipped into the single digits on the
mornings of the 7th and 12th when 7 degrees were
registered. The cold temperatures caused streets to
glaze with ice...resulting in the death of a pedestrian
who was struck by a car in Denver. Three people died from
heart attacks while shoveling the heavy...wet snow.
8-10 In 1999...a windstorm caused 20 million dollars in damage
along the Front Range Urban Corridor from Fort Collins
south to Pueblo and to the east over the plains...making
the storm equal to the costliest windstorm ever...which
occurred in Boulder on January 17...1982. In metro Denver...
several homes were damaged as shingles were blown off roofs.
Large pieces of a roof torn off a strip mall in Lakewood
damaged several cars in a parking lot. Most of the damage
to homes consisted of broken fences...awnings...doors...and
windows. Scores of automobiles suffered broken or cracked
windshields and paint damage from flying debris. Multiple
accidents were triggered as several tractor-trailer rigs
were blown on their sides by the strong cross-winds.
Blowing dust and dirt caused near zero visibilities at
times. Both I-25 and I-76 were closed north and northeast
of Denver. State Highway 93 was closed between Golden and
Boulder. Several trees...power poles...and power lines were
downed...causing a number of outages as well as sparking a
few small grass fires. Highest wind gusts reached 112 mph
atop Niwot Ridge near the Continental Divide west of
Boulder...102 mph at Wondervu...100 mph at the National Center
for Atmospheric Research Mesa Lab in Boulder...98 mph at the

temperature records being set. High temperature of 81
degrees on the 9th set a new record maximum for the date.
High temperature of 80 degrees on the 10th equaled the
record maximum for the date. The unusually warm weather
for so early in April produced a late afternoon
thunderstorm on the 10th.

Range. While the strongest winds were in the foothills
north of Denver...wind gusts to 69 mph were recorded at
Jefferson County Airport in Broomfield. Northwest winds

of 40 to 50 mph with gusts as high as 60 mph piled the
snow into drifts of 3 to 6 feet deep. I-25 southbound was
closed at Lincoln Avenue. I-70 to the east was closed at
Gun Club Road. The combination of heavy wet snow and
damaging winds resulted in widespread electrical outages.
Denver International Airport was completely shut down for
the first time in its brief 6-year history. Power surges
and outages crippled the airport`s massive computer systems.
The airport was closed at 5:00 AM and did not re-open until
mid-afternoon on the 11th. The power outages resulted in
businesses and schools closing. Over all of northeastern

blizzard conditions across metro Denver. The combination
of heavy snow and strong winds forced the closure of Denver
International Airport...stranding thousands of travelers.
Long stretches of I-25...I-70...and I-76 were also closed
due to extensive blowing and drifting snow. Snow amounts
ranged from 1 to 2.5 feet in and near the eastern foothills
and over the Palmer Divide. Drifts were 2 to 5 feet in
depth. Downed power lines caused scattered electrical
outages. Storm total snowfall amounts in and near the
foothills included: 31 inches near Conifer; 27.5 inches in

continued as such into the evening. North winds were
sustained to only 13 mph on the 15th.
In 1999...a spring storm dumped heavy snow over portions of
metro Denver. Nearly 2 feet of snow fell in the foothills
with half a foot to a foot over western and southern
suburbs. The heavy snow alleviated drought conditions
and associated high fire danger that prevailed during much
of the winter season. Snowfall totals included: 22 inches
in Coal Creek Canyon...20 inches at Wondervu...19 inches at
Genesee...17 inches near Evergreen and Nederland and at Idaho
Springs and Tiny Town...14 inches at Georgetown...13 inches at

reduced to 1/2 mile in blowing dust at Stapleton Airport.
In 1998...another spring storm brought heavy snow to the
foothills. Thirty to 40 vehicles were involved in
accidents along I-70 near Georgetown. The combination
of poor visibilities...slick roads...and careless drivers
led to the multi-car pileups. Only minor injuries were
reported. The accidents forced the closure of all of
I-70`s eastbound lanes. Snowfall totals included 12
inches at Genesee and 10 inches at Aspen Springs...Chief
Hosa...Georgetown...near Morrison...and on North Turkey
Creek. Only 0.1 inch of snow fell at the site of the
former Stapleton International Airport. East winds
gusted to 30 mph at Denver International Airport.
In 2002...unseasonable warm weather resulted in two records

16 In 1960...a wind storm struck all of metro Denver. Estimated
wind gusts up to 80 mph were registered in Boulder. At
Stapleton Airport sustained west-northwest winds over
50 mph with gusts as high as 70 mph produced some blowing
dust. The high winds damaged buildings...power and telephone
lines...and signs. Five people were injured in metro Denver
as a result of the wind storm. Blowing dust reduced
visibility at times. The winds were strong and gusty for
most of the day.
