...This week in metro Denver weather history...
1-5 In 1898...from the 1st to the 5th...snowfall totaled 15.5
inches in downtown Denver. Most of the snow...6.2 inches...
fell on the 3rd. Most of the snow melted as it fell.
The greatest snow depth on the ground was only 2.5 inches
on the 3rd at 8:00 PM. This was the only snowfall during
the month. Northeast winds were sustained to 22 mph on
the 1st.
2-5 In 2001...from the 2nd to the 5th...a very slow moving Pacific
storm system became parked near the Four Corners region...
which allowed heavy snow to develop above 6500 feet in the
foothills with a mix of rain and snow over lower elevations
of metro Denver. Snowfall totals included: 21 inches atop
Crow Hill and at Idaho Springs; 19 inches near Blackhawk;
and 18 inches in Coal Creek Canyon...Genesee...and 11 miles
southwest of Morrison. Snowfall totaled 6.2 inches at the
site of the former Stapleton International Airport.
Precipitation (rain and melted snow) totaled 2.09 inches at
Denver International Airport where north winds gusted to 30
mph on the 2nd.
3-5 In 1908...rain changed to snow on the evening of the 3rd
and continued through the early evening of the 5th.
Snowfall totaled 10.0 inches over downtown Denver.
This was the last measurable snow of the season.
Precipitation totaled 1.51 inches. North winds were
sustained to 23 mph on the 3rd...33 mph on the 4th...and
21 mph on the 5th. Three temperature records were set.
High temperatures of 30 degrees on the 4th and 38 degrees
on the 5th were record low maximum temperatures for the
dates. The reading on the 4th was also the all-time
record low maximum for the month of May.
In 2007...a slow moving Pacific storm system...from the
Desert Southwest...brought a period of unsettled weather
to the region. During the 3-day period...locally heavy
snow was reported over parts of the Front Range Foothills.
Storm totals included: 15 inches near Conifer...14.5
inches west of Jamestown...13.5 inches; 6 miles southwest
of Evergreen...and 12.5 inches at Pine Junction. Severe
thunderstorms...producing large hail...up to one inch in
diameter were observed in the vicinity of Boulder and
Hudson. Lightning struck a residence in Jefferson County.
The roof was hit...causing the attic to catch fire.
At Denver International Airport...lightning struck a
United Airlines jet as it was pushing away from
the gate. The passengers were taken off the jet and put
on another plane.
4-5 In 1986...the 4th to the 5th...high winds buffeted the
foothills. Wind speeds of 60 to 75 mph were recorded in
Boulder. At Stapleton International Airport...west winds
gusted to 45 mph on the 4th and to 40 mph on the 5th.
In 2000...a brief warm spell resulted in setting two daily
high temperature records. The temperature climbed to
highs of 87 degrees on the 4th and 89 degrees on the 5th.
4-8 In 1969...from the 4th to the 8th...heavy rains caused
flooding on Boulder Creek in Boulder...which resulted in
one death on the 7th. Flooding also occurred on Bear
Creek in Sheridan and on the South Platte River in Denver.
Rain over most of the eastern foothills started late on
the 4th and continued with only brief interruptions in
many areas until the morning of the 8th. Very high rates
of rainfall occurred on the 6th and 7th with the greatest
intensities in a band along the foothills from about 25
miles southwest of Denver northward to Estes Park. Storm
totals by both official and unofficial measurements
exceeded 10 inches over much of this area and were over 12
inches in some localities. Heavy snow fell in the higher
mountains and in the foothills later in the period. The
saturation of the soil resulted in numerous rock and land
slides...and the heavy run-off caused severe damage along
many streams and flooding on the South Platte River. Many
foothill communities were isolated as highways were blocked
and communications disrupted. Roads were severely damaged
over a wide area...and a large number of bridges washed out.
Many roads were closed due to the danger from falling
rocks. A building in Georgetown collapsed from the weight
of heavy wet snow. In Boulder...a man drowned when caught
by the flooding waters of Boulder Creek...and a patrolman was
injured. Rainfall totaled 7.60 inches in Boulder with
9.34 inches recorded at the Public Service Company electric
plant in Boulder Canyon. In Morrison...rainfall totaled
11.27 inches in 4 days. Heavy rainfall totaled 4.68 inches
at Stapleton International Airport over 3 days from the 5th
through the 7th. Rainfall of 3.14 inches was recorded in 24
hours on the 6th and 7th. Downstream flooding continued
along the South Platte River until the 12th when the flood
crest reached the Nebraska line.

the night into the 6th...and totaled 3.50 inches. Northeast
winds were sustained to 15 mph on the 5th.
In 1917...post-frontal rain changed to heavy snow...from the
5th to the 6th...and totaled 12.5 inches over downtown Denver.
Most of the snow...12.0 inches...fell on the 5th and this was
the greatest 24-hour snowfall ever measured during the month
of May. This was also the only measurable snow of the month
that year. Low temperatures of 27 degrees on the 5th and 23
degrees on the 6th were record minimums for the dates.

the Front Range. The greatest flash flooding occurred in
metro Denver where rainfall totaled 3.56 inches at Stapleton
International Airport. Flooding in metro Denver occurred
on Clear Creek and the South Platte River...already swollen
from heavy snowmelt. Numerous basements were flooded...
roads and streets were washed out...a bridge was demolished...
and miscellaneous other damage was reported. North winds
gusted to 39 mph at Stapleton International Airport during

along the South Platte River all the way to the Nebraska
border during the next two weeks. One person died and
total damage was estimated at around 120 million dollars.
In 1978...from the 5th to the 6th...heavy wet snow of around

hail...strong winds...heavy rain and flash flooding. Hail
up to baseball size...caused extensive property damage to
cars...homes and businesses across a large part of Denver
and the western suburbs including Arvada...Lakewood and
Wheat Ridge. According to the Rocky Mountain Insurance
Agency Association...the storm was Colorados most
expensive insured catastrophe...around $2.3 billion...and
the second costliest hailstorm in the United States.
The group estimated more than 150000 auto insurance
claims and 50000 homeowner insurance claims would be
filed. Businesses and homes sustained holes in siding
along with broken windows and torn screens. A severe
thunderstorm producing large hail...strong winds and heavy
rain impacted areas around Greeley as well. The high cost
incurred from the storm was due to a number of factors
including: the size of the hail...the densely populated
area...the time of day...the escalating costs to repair
high-tech cars...and more expensive homes. Colorado Mills
Mall in Lakewood was severely damaged after hail busted
skylights and caused flooding inside stores. The common
areas and tenant spaces suffered substantial water damage.
Extensive damage to electrical systems...mechanical systems...
including HVAC and lighting...were expected to keep the mall

destroyed...and even some ceiling tiles fell off. The storm
damage prompted school officials to close all thirteen Adams
12 Five Star schools in Commerce City and Beach Court
Elementary school in Denver. Most of the schools in the
Adams 12 Five Star District were at least 50 years old and
sustained flood damage. Large hail damaged an apartment
building near Regis University...shattered windows and
punctured the siding on the west-facing side of the building.
Hail and heavy rain clogged drains and caused flash flooding
throughout Greeley. Up to three feet of water covered the
roadway near U.S. 34 and U.S. 85. Greeley firefighters helped
several residents get out of garden level apartments that had
flooded. Several other businesses and buildings suffered
flood damage...including Greeley City Hall and an apartment
complex in Evans. The Greeley Mall was extensively damaged
when water poured into the mall from the roof and debris
inundated the main floor.
8-9 In 1957...from the 8th to the 9th...intense heavy rain

cloud or dust roll estimated 3 miles behind. Thick dust
followed with heavy gusts of wind. The temperature fell
15 degrees in 10 minutes following the twister. The mild
tornado did little damage except to unprotected frame
structures. Winds were sustained to 50 mph with the
passing of the tornado at Stapleton Airport. It was
visible to observers for 10 minutes and was lost from
sight as it traveled east into huge rolls of dust. Hail
and rain followed with a few hailstones as large as 1/2
inch in diameter downtown. No damage was reported from
the hail. Thunderstorm winds sustained to 31 mph produced
blowing dust downtown. Precipitation was only 0.07 inch.
