...Today in metro Denver weather history...

12-15 In 1927...snowfall totaled 8.5 inches in downtown Denver.
        Most of the snow fell on the 14th.  Northwest winds
        were sustained to 27 mph during the storm.
13-15 In 1945...heavy snowfall totaled 9.8 inches in downtown
        Denver.  Most of the snow...4.8 inches...fell on the 14th.
        Snow fell for a total of 53 consecutive hours.  This
        was the second big snow in less than 2 weeks.  The air
        mass was very cold for April.  High temperatures of 21
        degrees on the 14th and 32 degrees on the 15th were
        record low maximums for the those dates.
13-17 In 2001...a huge dust storm over southern and inner Mongolia
        during April 3rd through the 6th lifted desert dust into
        the jet stream.  This dust cloud moved over metro Denver
        on the 13th and persisted through the 17th.  The cloud
        created widespread haze...giving the sky a milkish cast
        due to the scattering of incoming solar radiation.
14-15 In 1873...on the 14th and 14th...north winds blew a gale
        during the afternoon on both days.  Winds were brisk
        throughout each day.
      In 1902...from the 14th to the 15th...snowfall totaled 6.0
        inches in downtown Denver. Most of the snow melted as it
        fell.  Northeast winds were sustained to 20 mph.
      In 1910...strong winds occurred on the 14th and 15th.  Northeast
        winds were sustained to 52 mph on the 14th.  North winds
        were sustained to 44 mph on the 15th.
      In 1921...from the 14th to the 15th...heavy snowfall and strong
        winds produced near-blizzard conditions in the city. Snowfall
        totaled 10.0 inches.  Strong north winds sustained to 48 mph
        with gusts to 54 mph on the 15th produced drifts to several
        feet in depth.  The heavy wet snow caused extensive damage
        to trees...utility poles...and buildings.  Precipitation
        from the storm was 1.73 inches.  Very heavy snow also fell
        in the foothills.  At Silver Lake...in the mountains west of
        Boulder...95 inches of snow fell in 32.5 hours on the 14th
        and 15th.
      In 1935...dense dust...apparently behind a dry cold front...
        enveloped the city at 1:00 PM on the 14th and persisted
        through the night.  The dust blew into the city on
        northeast winds sustained to 30 mph with gusts to 32 mph.
        By mid-morning on the 15th...the dust had become light and
        continued as such into the evening.  North winds were
        sustained to only 13 mph on the 15th.
      In 1999...from the 14th to the 15th...a spring storm dumped
        heavy snow over portions of metro Denver.  Nearly 2 feet
        of snow fell in the foothills with half a foot to a foot over
        western and southern suburbs.  The heavy snow alleviated
        drought conditions and associated high fire danger that
        prevailed during much of the winter season.  Snowfall totals
        included:  22 inches in Coal Creek Canyon...20 inches at
        Wondervu...19 inches at Genesee...17 inches near Evergreen and
        Nederland and at Idaho Springs and Tiny Town...14 inches at
        Georgetown...13 inches at Morrison...10 inches near Sedalia...9
        inches in south Boulder...8 inches at Highlands Ranch and
        Wheat Ridge...and 7 inches at Littleton and Parker.  Only 3.4
        inches of snow fell at the site of the former Stapleton
        International Airport.  North-northwest winds gusted to 41
        mph on the 15th at Denver International Airport.
      In 2021...a storm system produced bands of heavier snow in and
        near the Front Range Foothills...where storm totals ranged
        from 8 to nearly 14 inches. Further east...storm totals ranged
        from 3 to 7 inches...including 5.7 inches at Denver
        International Airport.
15    In 1874...light snow developed around daybreak and became
        moderate to heavy by mid-morning and continued into the
        early evening.  While most of the snow melted as it fell...
        total precipitation from the melted snow was 0.95 inch.
        This would make the estimated snowfall nearly 10 inches.
      In 1963...high winds were widespread across metro Denver.
        West winds gusted to 63 mph in Denver at Stapleton Airport
        with sustained winds of 35 mph and gusts to 70 mph in
        downtown Boulder.  The winds caused extensive damage to
        buildings and other property.  Visibility was briefly
        reduced to 1/2 mile in blowing dust at Stapleton Airport.
      In 1998...another spring storm brought heavy snow to the
        foothills.  Thirty to 40 vehicles were involved in
        accidents along I-70 near Georgetown.  The combination
        of poor visibilities...slick roads...and careless drivers
        led to the multi-car pileups.  Only minor injuries were
        reported.  The accidents forced the closure of all of
        I-70`s eastbound lanes.  Snowfall totals included 12
        inches at Genesee and 10 inches at Aspen Springs...Chief
        Hosa...Georgetown...near Morrison...and on North Turkey
        Creek.  Only 0.1 inch of snow fell at the site of the
        former Stapleton International Airport.  East winds
        gusted to 30 mph at Denver International Airport.
      In 2002...unseasonable warm weather resulted in two records
        being broken.  The high temperature of 84 degrees was a
        record maximum for the date.  The low temperature of 57
        degrees was a record high minimum for the date.
15-16 In 1900...from the 15th to the 16th...heavy rainfall totaled
        2.33 inches.  A trace of snow was mixed with the rain at
        times.
      In 1950...from the 15th to the 16th...thunderstorms and heavy
        rain behind a cold front produced 2.13 inches of rain in
        24 hours at Stapleton Airport.
      In 2003...a fast moving Pacific storm system moved across
        Colorado allowing strong winds to develop over the eastern
        foothills and metro Denver from the 15th to the 16th.
        Northwest winds gusted to 59 mph at Denver International
        Airport late in the evening of the 15th.
      In 2016...1.22 inches of precipitation was measured at Denver
        International Airport which was the greatest daily amount
        for the month.
      In 2020...a potent storm system dropped out of the northern
        Rockies and produced moderate to heavy snow over portions
        of the Front Range mountains...foothills and adjacent
        plains. The heaviest snow fell in and near the foothills
        north of I-70.  In the mountains and foothills...storm
        totals included: 30 inches near Jamestown...27 inches
        near Nederland...22 inches near Allenspark...21 inches near
        St Mary`s Glacier...18 inches in Estes Park...16 inches near
        Crescent Village and Deer Ridge...15.5 inches near Aspen
        Springs...and 15 inches near Pinecliffe.  In Boulder...16.9
        inches of snow helped to establish a new seasonal snowfall
        record of 151.2 inches.  The previous seasonal snowfall
        record in Boulder was 142.9 inches in 1908-1909.  Along
        the I-25 corridor...storm totals included: 14.5 inches in
        Niwot...13.5 inches in Frederick...13 inches in Broomfield...
        12 inches in Lafayette and near Longmont...10.5 inches in
        Arvada...10 inches in Erie...Louisville...and Westminster...7
        inches in Brighton...6.5 inches in Edgewater and
        Northglenn...and 5.5 inches in Greeley. Snowfall totaled
        1.9 inches at Denver International Airport.
       In 2021...a storm system produced bands of heavy snow in
        and near the Front Range Foothills.  Storm totals included:
        13.8 inches at St. Mary`s Glacier...12.9 inches at Aspen
        Park...10 inches in Genesee...9.5 inches at Ken Caryl...9
        inches in Crescent Village...8.5 inches in Arvada and
        Westminster...8 inches at Evergreen and Sedalia...with
        3 to 7 inches elsewhere.  At Denver International Airport...
        5.7 inches inches of snowfall was observed.
15-17 In 1922...from the 15th to the 17th...heavy snowfall totaled
        9.0 inches in downtown Denver.  Most of the snow...6.0 inches...
        fell on the 16th.  This was the third major snowstorm in a
        week.  Northwest winds were sustained to 43 mph with gusts
        to 47 mph on the 15th.
      In 2016...a powerful spring snowstorm brought heavy...wet snow
        to areas in and near the Front Range Foothills and Palmer
        Divide.  Storm totals generally ranged from 2 to 4 feet in
        the foothills with 1 to 2 feet in the mountain west of
        Denver and along the Palmer Divide. Along the I-25 Corridor
        storm totals ranged from 6 to 20 inches...with highest
        amounts across the western and southern suburbs. Some of
        those totals included: 16 inches in Aurora and Superior...15
        inches at the National Weather Service Office in Boulder...
        14.5 inches in Broomfield...13.5 inches in Westminster...
        officially 12.1 inches at Denver International Airport...12
        inches in Louisville...11.5 inches in Arvada...11 inches near
        Englewood...and 10.5 inches near Wheat Ridge. At Denver
        International Airport...there were 852 flight cancellations...
        most of which occurred on the 16th. The heavy wet snowfall
        broke trees limbs and caused scattered power outages. Over
        five thousand customers were without power on the 16th...and
        over two thousand on the 17th. Xcel Energy brought in extra
        crews from surrounding states to help restore power and
        minimize outage times through the storm. Numerous but mostly
        temporary road closures from 1 to 5 hours occurred throughout
        the storm. This included portions of I-70 east and west of
        Denver...Highway 103 from Idaho Springs to Evergreen and
        Highway 119 through Black Hawk.
