...Today in metro Denver weather history...
2-3 In 1974...heavy snowfall totaled 6.1 inches at Stapleton
International Airport where north winds gusted to 23 mph
on the 3rd. Most of the snow fell on the 3rd. Maximum
snow depth on the ground was 5 inches.
In 1990...a winter storm dumped 3 to 8 inches of heavy wet
snow across metro Denver. In the foothills snow amounts
ranged from 4 to 10 inches. Slushy snow and ice-covered
roads snarled traffic. The snow...ice...and poor visibilities
were blamed for numerous traffic accidents. Low clouds...
fog...and snow delayed air traffic at Stapleton International
Airport for at least 90 minutes on the afternoon of the 2nd.
Snowfall totaled 5.4 inches at Stapleton International
Airport where north winds gusted to 21 mph.
In 2018...a powerful and moist Pacific jet stream brought a
period of moderate to heavy snow and blowing snow to the
mountains west of Denver with up to a foot of snow.
A strong gust front generated from dissipating showers
near the foothills of southeast Larimer and eastern
Boulder counties pushed across the I-25 corridor and
adjacent plains. As the gust front swept across Denver
International Airport...a peak wind gust to 58 mph was
observed from the west-northwest.
2-5 In 1946...a major snow storm dumped 30.4 inches of heavy
snowfall downtown and 31.0 inches at Stapleton Airport.
The winter storm closed schools and disrupted all forms of
transportation in the city. The greatest depth of snow on
the ground was 28 inches at the airport. The duration of
the snowfall...from 4:22 AM on the 2nd to 3:08 AM on the 5th...
a total of 70 hours and 46 minutes...is the second longest
period of continuous precipitation on record and the second
heaviest snowfall of record at the time in Denver. The 17.7
inches of snowfall on the 2nd and 3rd was the greatest 24-
hour snowfall ever recorded during the month of November.
Buses and street cars had a difficult time...and many cars
were abandoned along roadsides and streets for several days.
Secondary roads in rural areas were blocked for 2 to 3
weeks. Several buildings in the city collapsed or were
damaged from the weight of the heavy snow. Football games
were canceled. Livestock losses were high over eastern
Colorado. The precipitation from this storm alone exceeded
the greatest amount ever recorded in Denver during the
entire month of November previously. The precipitation
recorded downtown was 2.03 inches...and the previous record
for the entire month of November was 1.95 inches in 1922.
North winds were sustained to 26 mph on the 2nd.
3 In 1940...the longest period without snow...200 days...ended on
this date with the first snow of the season...a trace...on
November 4...1940. The last snow of the previous season...
also a trace...occurred on April 17...1940.
In 1959...a rare thunderstorm in November occurred around
sunrise. Rainfall measured only 0.02 inch at Stapleton
Airport.
In 1993...periodic high winds buffeted the foothills west
of Denver. Wind gusts to 90 mph were recorded at
Rollinsville in the foothills southwest of Boulder...while
gusts to 85 mph were observed atop Squaw Mountain near
Idaho Springs. West winds gusted to 37 mph at Stapleton
International Airport.
In 1996...a rare November thunderstorm during the early
evening produced 0.10 inch of rain at Denver International
Airport and only 0.06 inch of rain at the site of the former
Stapleton International Airport.
In 2005...strong winds developed over the Urban Corridor.
While the damaging winds were in the Fort Collins area...
high winds also developed to the south of Denver in
Douglas County. Peak wind reports included 70 mph at
Franktown...65 mph in Castle Rock...and 61 mph in Sedalia.
West winds gusting as high as 47 mph warmed the temperature
to a high of 69 degrees at Denver International Airport.
Winds were strong and gusty for most of the daytime hours
across metro Denver.
3-4 In 1994...a fast moving snow storm dumped 8 to 9 inches of
snow on Boulder...Broomfield...and Lafayette. Snowfall
totaled only 1.8 inches at Stapleton International Airport
where on the 3rd east winds gusted to 20 mph and some
freezing drizzle fell.
In 2022...a massive crash occurred as freezing temperatures and
icy conditions followed the first snowfall of the season...
most of which fell the previous evening. Hazardous conditions
developed in Denver along an elevated portion of 6th Avenue
during the early morning commute. The crash involved
approximately 100 vehicles. There were no serious injuries...
although one driver had to be extricated from a vehicle. The
accidents occurred between Kalamath Street and Federal Boulevard.
Numerous tow trucks took damaged or inoperable vehicles to a
parking lot outside Empower Field at Mile High. The icy road
conditions made it impossible for drivers to prevent from
slamming into each other. A major cleanup had to take place
before 6th was reopened later in the morning. The closure
lasted approximately 5 hours. Several crashes occurred along
Interstates 25 and 70...and included a multi-vehicle accident
on the onramp from US 36 to I-25. Storm totals in the
mountains and foothills generally ranged from 4 to 12 inches.
At the National Weather Service in Boulder...6.6 inches of
snowfall was observed. At Denver International Airport...4.5
inches was observed.
