... Today in Metro Denver weather history...
18-20 in 1966... sub-freezing temperatures caused thousands of
dollars in damage to fruit trees across Metro Denver.
Minimum temperatures were in the teens each morning and
failed to reach above freezing on the 19th. The low
temperature of 13 on the 20th set a new record minimum for
the date. Snowfall totaled 5.7 inches at Stapleton
International Airport during the period.
19-20 in 1892... rain on the 18th changed to snow on the 19th and
totaled 6.0 inches over downtown Denver into the 20th.
Total precipitation was 1.56 inches. North winds were
sustained to 26 mph on the 19th.
In 1907... a major storm dumped 18.0 inches of snowfall in
downtown Denver. Much of the heavy wet snow melted as
it fell. The most snow on the ground was 7.0 inches at
6:00 PM on the 19th. North to northeast winds were
sustained to 42 mph on the 19th and to 21 mph on the
20th. High temperatures were in the low to mid 30's
with low readings around 20.
19-21 in 1984... a large snowstorm buried most of Colorado under a
thick mantle of wet snow. Total snow amounts ranged from
10 to 20 inches across Metro Denver and a whopping 20 to
40 inches in the adjacent foothills. The snow closed roads
and damaged electrical transformers... causing numerous power
outages. Nearly 14 inches (13.6) of snow fell at Stapleton
International Airport where the combination of snow and
wind closed all but one runway... resulting in the cancellation
of many flights. Both I-70 and I-76 were closed to the east
19-22 in 1933... a major storm dumped 16.8 inches of snowfall over
downtown Denver when rain changed to snow during the early
morning of the 20th and continued through midday of the
22nd. Most of the snow fell on the 21st. Due to melting...
the most snow on the ground was 10.5 inches at 6:00 PM on the
21st. Before the snow started... a strong cold front on the
evening of the 19th produced north winds sustained to 35 mph
with gusts to 37 mph. The strong winds deposited a thin
layer of dust on the city. North to northwest winds were
sustained to 31 mph with gusts to 35 mph on the 20th and to
29 mph with gusts to 32 mph on the 21st.
20 in 1874... light snow fell for most of the day... but melted almost
as fast as it fell. The flakes... as large as 1 1/2 inches in
diameter during the afternoon... resembled white feathers.
Precipitation from melted snow was only 0.21 inch in the
city. Snowfall was much heavier in the mountain Parks
where snow depths were reported between 3 and 5 feet from
the storms of the 15th and 20th. The heavy snow resulted
in the deaths of hundreds of cattle and sheep.
In 1875... the city was enveloped in a severe wind and sand
storm. For nearly 30 minutes before the storm... it could
be seen moving toward the city from the northwest as a black
wall of clouds extending only 10 degrees above the horizon.
At 5:30 PM... the sand was sweeping past in such clouds that
objects at a distance of only 10 yards were not visible.
The streets were entirely deserted. The greatest velocity
of wind during the storm was 36 mph from the north-northwest.
The storm diminished by 7:00 PM. Swarms of grasshoppers were
seen today and were reported in all parts of the territory.
In 1897... southwest winds were sustained to 46 mph with gusts
to 50 mph. The apparent Chinook winds warmed the
temperature to a high of 76 degrees.
In 1905... apparent Post-frontal north winds were sustained to
In 1912... west winds were sustained to 42 mph with an extreme
velocity of 48 mph.
In 1958... strong Chinook winds gusted to 52 mph at Stapleton
In 1981... 3/4 inch hail fell in Lakewood with up to one half
inch of rain in a few minutes across northern sections of
of the city of Denver. Thunderstorm rainfall totaled
0.39 inches at Stapleton International Airport... where
1/4 inch hail was also measured.
In 1987... 6 to 12 inches of heavy snow fell in the foothills.
Only 2.5 inches of snow fell at Stapleton International
Airport where the usual flight delays occurred.
In 2005... severe thunderstorms produced large hail across
Metro Denver. Hail as large as 1 3/4 inches in diameter
fell at Denver International Airport. Hail to 3/4 inch
in diameter fell in and near Golden and near Hudson...
Keenesburg... Barr Lake... and Bennett.
In 2013... an avalanche pushed a group of six snow boarders
into the sheep creek Gully of Loveland Pass. This is
near but outside the Loveland ski area boundary. Five of
the six members of the group died as they were completely
buried. The avalanche is the deadliest in Colorado since
1962 when seven people were killed when a slide buried
residents at Twin Lakes near Independence Pass.
20-22 in 1957... strong and gusty south to southeast winds raked
Metro Denver each day. The strongest wind gust of 55 mph
occurred on the 21st when blowing dust briefly reduced the
visibility to 3/4 mile at Stapleton Airport.
20-23 in 1989... unusually warm weather resulted in several daily
temperature records being broken in Denver. The high
temperature of 89 degrees on the 21st exceeded the record
maximum for the month at that time. Daily record high
temperatures were either exceeded or equaled with 83
degrees on the 20th... 88 degrees on the 22nd... and 85
degrees on the 23rd. The low temperature of 55 degrees
on the 22nd equaled the record high minimum for the date.
