...Today in metro Denver weather history...
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.
6-7 In 1873...from the 6th to the 7th...snowfall totaled 8.9 inches
in downtown Denver. Most of the snow fell on the 6th.
7 In 1904...west winds were sustained to 48 mph with gusts to
60 mph. A shower produced 0.16 inch of rain.
In 1953...a microburst caused a brief wind gust to 58 mph at
Stapleton Airport.
In 1958...3/4 inch diameter hail fell over south metro Denver...
10 miles southwest of Stapleton Airport.
In 1977...baseball size hail damaged windows in Wheat Ridge.
Hail was 4 inches deep on the ground in Arvada. Hail 3/4
to 1 inch diameter fell in Westminster and Kittredge.
In 1990...a fast moving cold front produced wind gusts of 40
to 60 mph. Brighton reported a wind gust to 57 mph...while
north wind gusts to 44 mph were measured at Stapleton
International Airport.
In 1995...severe thunderstorms struck Aurora. Hail piled 4 to
5 inches deep in the vicinity of Quincy Reservoir in south
Aurora. Lightning struck an Aurora Police communications
tower causing significant malfunction to the primary
system. Minor damage was sustained when lightning struck
an apartment building. Hail...up to 1 1/4 inches in
diameter...while soft and slushy...accumulated up to 6 inches
deep in 15 minutes. Many streets were closed for an hour
or more due to flooding caused by heavy rain and melting
hail stones. Some trees were stripped of their leaves.
Hail as large as 1/2 inch diameter was measured at Denver
International Airport where a funnel cloud was sighted.
In 2003...a tornado touched down briefly near Bennett...but
did no reported damage.
In 2005...severe thunderstorms produced 3/4 inch hail near
Brighton and a thunderstorm wind gust to 60 mph near
Fort Lupton.
In 2014...severe thunderstorms produced large hail...from 1 to
1 1/2 inches in diameter...across parts of Arvada...Broomfield...
Dacono...Northglenn and Thornton.
In 2015...a severe thunderstorm produced hail...up to walnut
size...in Elbert County. A weak tornado touched down briefly
near Ft. Lupton.
In 2017...a 37-year-old woman and her horse were killed near
Sedalia after lightning hit a nearby tree. A teenage girl was
also seriously injured. Damaging microburst winds downed
trees and power poles across parts of Adams...Arapahoe...Denver
and Douglas Counties. Electrical lines and branches were also
snapped causing scattered power outages.
7-8 In 1958...rainfall from the 7th to the 8th...totaled 2.50 inches
at Stapleton Airport.

Public Information Statement

259 AM MDT WED MAY 8 2024
...Today in metro Denver weather history...
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.
7-8 In 1958...rainfall from the 7th to the 8th...totaled 2.50 inches
at Stapleton Airport.
8 In 1873...a very light rain fell until 5:00 AM...when it
turned into light snow and sleet and was accompanied by
brisk northeast winds. The snow froze as it fell...
breaking the telegraph lines in many places.
Precipitation totaled only 0.14 inch in the city.
In 1883...a severe rain and hailstorm struck the city. In
25 minutes the hail was 5 inches deep in the vicinity of
the weather office in downtown Denver and reported as
deep as 10 to 12 inches in other parts of the city.
Gutters were blocked by the hail...and many cellars were
flooded. Precipitation from the storm was 1.90 inches
with the total for the day recorded at 2.02 inches. The
size of the hail was not recorded.
In 1988...a wind gust to 68 mph was recorded at Echo Lake.
Northwest winds gusted to 35 mph at Stapleton Airport.
In 1995...high winds of unknown strength blew a camper shell
from the back of a pickup truck near Fort Lupton. North
winds gusted to 49 mph at Denver International Airport.
In 1996...1 to 2 inch diameter hail was measured in
Lochbuie northeast of Denver. Bean size hail fell in
Brighton. The large hail fell from severe thunderstorms
to the northeast of metro Denver.
In 2003...tornadoes touched down briefly near Brighton...
Watkins...and Strasburg...but did no reported damage.
Hail to 3/4 inch in diameter was measured near Hudson.
In 2017...severe thunderstorms broke out across Denver and
the surrounding metro area and produced large damaging
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 Colorado’s 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
closed for several months. In Lakewood...the loss in sales
tax was projected to be about $350000 per month...which was
3 to 4 percent of the city's monthly budget. Prestige
Imports in Lakewood...estimated 250 to 300 Audis and Porches
were damaged by the storm. Some of those vehicles were
valued at nearly $200000 each. Significant damage was
reported at Lutheran Medical Center after the hailstorm tore
through Wheat Ridge. The hospital building and some of the
medical office buildings sustained broken windows. The storm
also hit the office of the Colorado Bureau of Investigation
in Lakewood. The offices were flooded...several cubicles
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
caused flash flooding on Toll Gate Creek in Aurora
where 3 people were killed in a car. Up to 4 inches of
rain fell in 5 hours in the Toll Gate Creek basin.
The rain also caused flash flooding on Sand Creek in
Aurora and Denver. Rainfall totaled 3.29 inches
at Stapleton Airport with most of the rain...2.34 inches...
occurring on the 9th.
8-10 In 1979...from the 8th to the 10th...4.3 inches of snow
fell at Stapleton International Airport where northwest
winds gusted to 30 mph on the 8th. Most of the snowfall...
2.3 inches...occurred on the 9th. High temperature of only
35 degrees on the 9th equaled the record low maximum for
the date.

...Live NOAA Weather Radio Test with Larimer Emergency Telephone
Authority...
On Monday, May 13th at 6 PM Mountain Daylight Time, the National
Weather Service Forecast Office in Boulder, Colorado will conduct
a live NOAA Weather Radio test in coordination with the Larimer
Emergency Telephone Authority (LETA). The test message will
originate with LETA using the ‘Demonstration’ (DMO) code which
will not trigger the Emergency Alert System (EAS) and will not
activate older NWR receivers with the 1050 Hz Warning Alarm Tone.
The test message will be broadcast one time only on NWR stations
WXJ45, KEC76, WXM92, WXM50, and WXM51. NOAA Weather Radios
equipped with Specific Area Message Encoding (SAME) and programmed
for Larimer County (location code 008069) will generally default
to silence for this test message; this means the receiver will not
activate with a warning tone, although your radio device will
still visibly light up to highlight that a test message was
received.
When you use our homepage, www.weather.gov/bou, you will also see
Larimer County highlighted for the DMO test message.
In the event severe weather is forecast or occurring on May 13th,
the test will not be conducted and will be postponed to another
day and preceded by another Public Information Statement.
