...Today 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...from the 18th to the 19th...heavy snowfall totaled
        8.4 inches over downtown Denver.  Northeast winds were
        sustained to 17 mph.
      In 1993...from the 18th to the 19th...sporadic high winds
        occurred across metro Denver. Peak 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 damaged 3 homes under
        construction in Broomfield.  Northwest winds gusted to 55
        mph at Stapleton International Airport.
      In 1995...from the 18th to the 19th...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...from the 18th to the 20th...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

        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.
      In 2021...moderate to heavy snow occurred in and near the
        Front Range Foothills...with the heaviest amounts in and
        near the foothills of Boulder and northern Jefferson
        counties. Storm totals ranged from 8 to 16 inches in
        those areas...with 2 to 7 inches across the rest of the
        I-25 Corridor.  The National Weather Service Office in
        Boulder measured 8.9 inches...with a measurement of 3.1
        inches of snowfall at Denver International Airport.
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.
