...Today in metro Denver weather history...
9-10 In 2005...a major winter storm brought heavy...wet snowfall
to the Front Range Mountains...eastern foothills...portions
of metro Denver...and the Palmer Divide. Snow accumulations
ranged from 8 to 26 inches with drifts from 3 to 4 feet
in places. The heaviest snow occurred to the east and
southeast of the city...closing most major highways in
that area...including I-70 from Denver to Limon. The Red
Cross opened four shelters for people who were stranded
along I-70 in eastern Colorado. Since many trees had not
yet shed their leaves...the storm caused significant tree
damage. One woman in Denver was killed when a tree branch...
8 to 10 inches in diameter...snapped under the weight of the
heavy...wet snow and struck her as she was shoveling her
driveway. Xcel Energy reported power outages to about 35
thousand customers. Several incoming flights were delayed
at Denver International Airport. Snow totals included: 16
inches in the foothills near Boulder...12 inches at Genesee
and near Golden...22 inches near Watkins...19 inches near
Bennett...17 inches southeast of Aurora...14 inches near
Parker...13 inches near Castle Rock...12 inches in Centennial...
11 inches in Parker...and 10 inches at Denver International
Airport and in Littleton. While many areas of metro Denver
received heavy snow...others experienced almost entirely rain.
This included west and northwest metro Denver...Boulder...and
Longmont. Rainfall amounts were significant as storm totals
ranged between 1.50 and 2.50 inches. The steady rainfall
triggered 3 rockslides in foothills canyons. Two of the
slides occurred on State Highway 119 in Boulder Canyon and
the longest slide...7 feet in length...on State Highway 74 in
Bear Creek Canyon at Idledale. North winds were sustained
to around 23 mph with gusts to 31 mph at Denver International
Airport on the 9th. The high temperature of only 34 degrees
on the 10th was a record low maximum for the date. The low
temperature on both days was 32 degrees.
10 In 1901...an evening thunderstorm produced east winds to
43 mph with gusts to 48 mph.
In 1949...strong winds believed to be the worst in Boulder`s
history at the time caused over 100 thousand dollars
damage in the city. Peak winds were estimated to 85 mph
at Valmont...just east of Boulder. High winds also
occurred over most of metro Denver and caused damage to
trees...window glass...and utility lines. The damage was
most pronounced over the northwest metro area...including
north Denver and Lakewood. Falling tree branches caused
damage to parked autos and houses. Wind gusts to 70 mph
were recorded at Stapleton Airport.
In 1964...lightning struck and killed a 13-year-old boy...while
he was riding his bicycle along a tree-lined residential
street in south Denver. Apparent microburst winds gusted
to 54 mph at Stapleton International Airport.
10-11 In 1986...the first significant snowstorm of the season
produced 2 to 5 inches of snow over metro Denver with 5
to 10 inches in the foothills west of Denver. Wondervu
recorded the most snow from the storm...13 inches. The
heavy wet snow caused numerous power outages. The storm
was accompanied by strong north winds with gusts to 41 mph
recorded on the 10th. The first snowfall of the season
totaled 3.1 inches at Stapleton International Airport with
only one inch on the ground due to melting. The strong
cold front accompanying the storm cooled the temperature
from a high of 73 degrees on the 10th to a high of only
33 degrees on the 11th...which was a record low maximum
for the date.
10-12 In 1969...the second heavy snowstorm in less than a week
dumped nearly a foot of snow across metro Denver and
plunged the area into extremely cold temperatures for so
early in the season. Snowfall totaled 11.0 inches at
Stapleton International Airport. North winds gusting to
26 mph produced drifts up to 2 feet deep. Temperatures
dipped from a high of 52 degrees on the 10th to a record
low for the date of 10 degrees on the 12th. There was
additional damage to trees and power and telephone lines
from heavy snow accumulations and icing. Travel was
restricted or blocked by drifting snow in both the
mountains and on the plains east of Denver.
