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

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.
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

        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...

        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...

        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.
16    In 1960...a wind storm struck all of metro Denver.  Estimated
        wind gusts up to 80 mph were registered in Boulder.  At
        Stapleton Airport sustained west-northwest winds over
        50 mph with gusts as high as 70 mph produced some blowing
        dust.  The high winds damaged buildings...power and telephone
        lines...and signs.  Five people were injured in metro Denver
        as a result of the wind storm.  Blowing dust reduced
        visibility at times.  The winds were strong and gusty for
        most of the day.
16-17 In 1944...from the 16th to the 17th...heavy snowfall totaled

        sustained to 18 mph on the 16th.
16-18 In 2009...from the 16th to the 18th...a potent spring storm
        brought heavy snow to locations in and near the Front Range
        Foothills.  A deep easterly upslope produced nearly 5 feet
        of snow in parts of the foothills.  The heavy snow resulted
        in the closure of Interstate 70...from Golden west to Vail...
        for approximately 16 hours.  The heavy snow snapped power
        lines in Evergreen and Nederland.  The ensuing outages
        affected 14200 residents.  In the Front Range Foothills...
