Public Information Statement

Statement as of 6:45 PM MDT on April 18, 2015


... This week in Metro Denver weather history...

17-19 in 1920... snow fell across the city continuously for 57 hours...
        from the early morning of the 17th until 11:40 am on the
        19th. The heavy wet snowfall totaled 18.2 inches with the
        greatest accumulation on the ground of 12 inches. Winds
        during the storm were strong with sustained speeds in
        excess of 27 mph for over 40 consecutive hours... which
        created near-blizzard conditions. The highest recorded
        wind speeds were 44 mph with gusts to 50 mph from the
        north on the 17th and 39 mph with gusts to 48 mph from
        the northwest on the 18th. The strong winds piled the
        snow into high drifts which stopped all Denver traffic.
        Railroads were blocked with only one train entering the
        city on the 19th. All interurban trains were blocked... as
        were the 13 trolley lines. Thus... many workers were unable
        to get home at night and filled all of the downtown hotels
        to capacity. No grocery or fuel deliveries were possible...
        except milk and Coal to hospitals and to families with
        babies. No lives were lost in the city... but several people
        perished in surrounding districts. Stock losses were heavy
        on the plains. Temperatures during the storm were in the
        20's.
18-19 in 1884... a major storm dumped 13.8 inches of snowfall on
        downtown Denver. Most of the snow... 10.0 inches... fell on
        the 18th. Light rain on the early morning of the 18th
        changed to heavy snow at 8:00 am and became light after
        2:00 PM but continued until 4:00 am on the 19th. The
        snow melted nearly as fast as it fell. There were only
        3 inches on the ground early on the morning of the 19th.
      In 1941... heavy snowfall totaled 8.4 inches over downtown
        Denver. Northeast winds were sustained to 17 mph.
      In 1993... sporadic high winds occurred across Metro Denver.
        Significant wind gusts included 97 mph at Rollinsville...
        80 mph in southwest Boulder... and 55 mph at Stapleton
        International Airport. The strong winds snapped a Pine
        Tree top... about 15 feet long and 8 inches in diameter... which
        crashed through the roof of a church in Evergreen... causing
        one thousand dollars in damage. Wind gusts of 50 to 60 mph
        caused structural damage to 3 homes under construction in
        Broomfield. Northwest winds gusted to 55 mph at Stapleton
        International Airport.
      In 1995... the second Spring storm of the month dumped heavy
        snow in the foothills. The upslope flow along with areas of
        thunder snow dropped 6 to 12 inches of snow in the foothills
        west of Denver and Boulder. Snowfall totaled 4.6 inches at
        the site of the former Stapleton International Airport... but
        most of the snow melted as it fell. East winds gusted to
        29 mph at Denver International Airport on the 18th.
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 in 1899... northwest winds were sustained to 48 mph with
        gusts as high as 60 mph in the city.
      In 1941... the last snow of the season... 0.4 inch... occurred...
        marking the end of the shortest snow season... 167 days.
        The first snow of the season... a trace... occurred on
        November 4... 1940.
      In 1954... strong gusty winds raked Metro Denver for most of
        the day producing some blowing dust. At midday... a severe
        dust devil was sighted in the Westwood area of southwest
        Denver.
      In 1955... cold west winds at 52 mph with gusts as high as 69
        mph were recorded at Stapleton Airport where blowing dust
        reduced the visibility to 1/2 mile.
      In 1960... the second wind storm in 3 days produced sustained
        west winds up to 44 mph with gusts as high as 58 mph at
        Stapleton Airport. Winds were strong and gusty most of
        the day... but no damage was reported.
      In 1963... the second windy day in a row produced west-
        northwest wind gusts to 52 mph at Stapleton Airport.
      In 1971... a tornado occurred in the southwest corner of Weld
        County about 10 miles west-northwest of Brighton. The
        storm moved through a farm yard damaging equipment and
        structures. The strong tornadic winds lifted a stock tank
        over 2 fences into a Corral 150 feet away. Later... a
        tornado touched down briefly west-southwest of Buckley
        field... 8 miles southeast of Stapleton International
        Airport. No damage was reported.
      In 1985... high winds occurred in the foothills. Winds gusted
        to 97 mph atop Squaw Mountain in the foothills west of
        Denver. West winds gusted to 37 mph at Stapleton
        International Airport.
      In 1987... a powerful cold front produced high winds and
        engulfed Metro Denver in huge clouds of blowing dust that
        lowered the visibility to as little as 100 yards. The cold
        front generated winds as high as 72 mph at Brighton... 67 mph
        in Thornton... and 54 mph at Stapleton International Airport.
        Winds of 50 to 70 mph were common along the Front Range from
        Denver north. The high wind gusts flipped a light plane
        taxiing at Stapleton International Airport... slightly
        injuring two people on board. The cold front dropped the
        temperature from a high of 80 degrees at 3:00 PM to a low of
        33 degrees at midnight. Nearly an inch of snow... 0.8 inch...
        fell at Stapleton International Airport before midnight.
      In 1988... a tornado touched down in Fort Lupton... following a
        path 50 to 75 yards wide for 2 1/2 blocks. The twister
        damaged roofs on 2 schools and broke numerous windows;
        about 10 houses were damaged and several cars had windows
        blown out. Several trees were downed.
      In 1989... winds were clocked to 68 mph in Wheat Ridge.
        Microburst winds gusted to 35 mph at Stapleton International
        Airport.
      In 1996... high winds gusting from 70 to near 100 mph developed
        in the Front Range foothills and adjacent plains. Numerous
        power outages were reported as power lines and poles were
        downed. The high winds blew the chimney off the roof of a
        house in Westminster. Numerous homes received minor shingle
        damage. Some of the stronger wind gusts included: 98 mph
        at Jefferson County Airport in Broomfield... 91 mph atop Squaw
        Mountain west of Denver... and 75 mph atop Table Mesa near
        Boulder. West northwest winds gusted to 45 mph at Denver
        International Airport.
      In 2001... westerly Chinook winds... gusting as high as 40 mph at
        Denver International Airport... prevented the low temperature
        from dropping below 51 degrees... setting a new record high
        minimum for the date. The high temperature of 77 degrees
        was not a record.
      In 2005... severe thunderstorms produced large hail across
        Metro Denver. Hail as large as 1 1/4 inches in diameter
        was measured in Arvada. Hail to 1 inch in diameter fell in
        Westminster... Northglenn... and Thornton. Hail to 7/8 inch
        was reported near Brighton... Barr Lake... and Castle Rock.
        Hail to 3/4 inch fell in Elizabeth and Broomfield and near
        Golden... Brighton... and Fort Lupton.
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
        of Denver.
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
        43 mph.
      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
        Airport.
      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.
21 in 1885... rain changed to snow during the early morning and
        was the heaviest snow of the season. Total snowfall was
        estimated at 8.0 inches over downtown Denver... but the
        snow melted rapidly on the ground as it fell. However...
        the weight of the snow... as well as northwest winds
        sustained to 29 mph downed Telegraph and telephone wires.
        Several large branches of trees were also broken by the
        weight of the snow. Precipitation totaled 1.01 inches
        from the storm.
      In 1887... west winds were sustained to 47 mph.
      In 1932... the temperature dipped to a low of only 60 degrees...
        the all-time record high minimum for the month.
      In 1988... a small tornado was observed by National Weather
        Service employees about 3 miles northwest of Thornton. It
        was on the ground for about 2 minutes. No damage was
        reported. Later... lightning struck two 14-year-old girls on
        a softball field in Westminster. One was killed... while the
        other suffered moderate injuries. Northwest winds gusted
        to 44 mph at Stapleton International Airport behind a
        cold front.
      In 2010... severe thunderstorms produced large hail... strong
        winds and a tornado across parts of Adams... Arapahoe...
        Elbert... and Weld counties. The hail... up to 1.50 inches
        in diameter... came down so heavy along parts of I-70
        and I-76 that snowplows had to be called out to remove
        it. Numerous vehicles were damaged by hail. In Weld
        County... very heavy rain and hail accompanied
        thunderstorm winds up to 75 mph. Hail up to 1.50 inches
        was reported near bennett; 1.25 inches... 5.3 miles east
        of englewood; 1.0 inch size hail near Buckley field; with
        0.88 inch size hail near Boulder. A weak tornado touched
        down briefly in Elbert County... about 9 miles southwest of
        Deer Trail... but did no damage. Several minor accidents
        were reported with snowpacked and slick Road conditions
        along with very low visibilities. Minor street flooding
        was reported in southeast Aurora. Denver International
        Airport recorded 0.30 inches of rainfall. Also... a peak
        wind gust to 36 mph from the southeast was observed at
        the Airport.
21-22 in 1910... north winds were sustained to 45 mph behind a cold
        front. Rainfall totaled 0.63 inch.
      In 1923... snowfall of 2.0 inches in the city was the only
        snow of the month and the last measurable snow of the
        season. Northwest winds were sustained to 25 mph on
        the 21st.
      In 1952... heavy snowfall totaled 7.6 inches at Stapleton
        Airport. The storm was accompanied by north winds gusting
        to 33 mph.
      In 2001... the second major snow storm in 11 days moved into
        Metro Denver with blizzard conditions developing again
        across the plains to the northeast of Denver. Snowfall
        amounts ranged up to 9 inches in Metro Denver with up to
        23 inches in the foothills. Northwest winds were sustained
        at 20 to 30 mph with gusts as high as 36 mph at Denver
        International Airport which was again shut down for nearly
        an hour by power outages on the 22nd. The outages affected
        lighting in the concourses... train operations... de-icing and
        refueling operations... flight information displays... and
        security screenings. Navigational aids were also affected...
        resulting in the cancellation of 58 arriving and departing
        flights which stranded about 5000 passengers. Across Metro
        Denver storm totals included: 9 inches at Eldorado springs;
        7 inches in boulder; 6 inches at ken caryl... Northglenn and
        near sedalia; and 5 inches in Arvada and Morrison. Only

        Denver and in the foothills. Nearly 3 feet of snow fell
        in the foothills with over a foot in the city. The heavy
        wet snow downed power lines in Douglas and Elbert counties.
        Scattered outages were reported at Parker... Franktown...
        Sedalia... and Castle Rock. Some residents were without
        electricity for as long as 20 hours. The inclement weather
        was blamed... at least in part... for several traffic accidents
        along the I-25 corridor between Denver and Castle Rock.
        Snowfall totals included: 32 inches at Idaho springs; 31
        inches on crowhill; 29 inches near evergreen; 26 inches at

        to 46 mph warmed the temperature to a high of 76 degrees.
      In 1958... west-northwest winds gusted to 48 mph at Stapleton
