stranded. Over 3000 families were without power.
Livestock losses were high. Metro Denver escaped the
main brunt of this storm. At Stapleton International

7 inches at Aspen Springs...Crow Hill...Intercanyon...and
Lake George. In metro Denver snowfall totals included:

snow producer. Snowfall totaled 10.7 inches in downtown
Denver with 9.5 inches recorded at Stapleton Airport. North
winds were sustained to 21 mph on the 1st; otherwise winds
were not strong. The air mass was very cold for April.

a record low maximum for the month. Warm weather following
the storm quickly melted the snow.

where 8.7 inches were measured. Snow began late on the 1st
and continued through early morning on the 3rd. Thunder

In 1957...a heavy snow storm dumped 17.3 inches of snow at
Stapleton Airport. Strong gusty north winds to 31 mph
reduced visibilities to 1/8 mile at times and created
blizzard conditions. The 24-hour snowfall had been
exceeded only twice in previous records...and the 24 hour
precipitation of 2.05 inches was the third heaviest of
previous record during April.
In 1959...a cold front produced strong gusty winds across
metro Denver. North winds gusting to 50 and 60 mph caused
some minor damage to power lines and signs and caused dust
storms on the plains east of Denver. A wind gust to 49 mph
was recorded at Stapleton Airport.
In 1966...northwest winds gusting to 52 mph produced blowing
dust...which briefly reduced the visibility to 1 mile at
Stapleton International Airport.
In 1975...the all-time lowest recorded temperature in April...
2 degrees below zero...occurred. This is also the latest
below zero reading for the season.

causing minor damage. Wind gusts to 127 mph were recorded
at Rocky Flats south of Boulder...116 mph at Wondervu...100
mph at Jefferson County Airport in Broomfield...and 56 mph at

2-3 In 1955...strong west to southwest winds raked metro Denver on
both days. Sustained winds as high as 37 mph with gusts to
60 mph were recorded at Stapleton Airport where the
visibility was reduced to 1/4 mile in blowing dust.
In 1974...a heavy snowfall of 6.7 inches was accompanied by
northeast wind gusts to 33 mph which produced some blowing
snow across metro Denver. Over eastern Colorado many
highways and schools were closed due to near-blizzard
conditions from the storm.
In 1986...the worst snow storm of the season blasted metro
Denver. Heavy snow and high winds combined to close roads...
schools...and airports. Portions of all interstate highways
out of Denver were closed at times. The snow came after an
exceptionally mild late winter and early spring; trees and
bushes had already bloomed and leafed out. The snow and
wind snapped many of these...causing power outages. Total
snowfall amounts in metro Denver ranged from 1 to 2 feet
with 2 to 3 feet in the foothills. Snowfall totaled 12.6
inches at Stapleton International Airport where north winds
gusting to 39 mph reduced the visibility to 1/8 mile in snow
and blowing snow. Most of the snow fell on the 3rd when
temperatures hovered around 30 degrees for most of the day.
The heavy snow halted traffic and closed businesses. A 59-
year-old man was found dead from exposure in northwest
Denver. The roof of a toy store in Northglenn collapsed.
A 100 thousand square foot section of a greenhouse roof
collapsed in Golden...destroying over a million dollars worth

and on Floyd Hill; 11 inches near Blackhawk...Morrison...and
