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

7-9   In 1913...from the 7th to the 9th...heavy snowfall totaled 10.9
        inches in downtown Denver behind a cold front.  Most of the
        snow fell on the 8th. Northeast winds were sustained to 35 mph
        with gusts to 38 mph on the 9th.
      In 1935...moderate dust blew into the city around 9:00 PM on
        the 7th and persisted until early afternoon on the 9th.
        Southeast winds were sustained to around 20 mph on the 7th
        and 8th.  Winds shifting to the west at sustained speeds
        to 20 mph cleared the dust from the air on the 9th.
7-12  In 1959...snow falling over a 5-day period totaled 20 to 30
        inches just east of the mountains...while over the plains
        blizzard conditions closed schools and blocked highways.
        The second big storm in two weeks dumped 16.4 inches of
        snowfall on Stapleton Airport with the most...11.6 inches...
        occurring on the 8th.  East winds gusted to 37 mph on the
        9th.  Temperatures dipped into the single digits on the
        mornings of the 7th and 12th when 7 degrees were
        registered.  The cold temperatures caused streets to
        glaze with ice...resulting in the death of a pedestrian
        who was struck by a car in Denver.  Three people died from
        heart attacks while shoveling the heavy...wet snow.
8-9   In 2013...from the 8th to the 9th...heavy snow developed in
        and near the Front Range Foothills and Palmer Divide as an
        upper level trough made its way across southern Colorado.
        Snowfall was enhanced locally with the presence of an upper
        level jet.  Storm totals included: 23 inches near Eldorado
        Springs...18 inches just west of Boulder...16.5 inches near
        Orodell...15 inches...4 miles west-northwest of Boulder; 13
        inches at Gold Hill; 12 inches at the National Weather
        Service Office in Boulder...11 inches in Ken Caryl; 8.5
        inches near Morrison; 8 inches at Genesee and Roxborough Park;
         7.5 inches near Arapahoe Park; with 6.5 inches at Denver
        International Airport.
8-10  In 1999...from the 8th to the 10th...a windstorm caused 20
        million dollars in damage along the Front Range Urban
        Corridor from Fort Collins south to Pueblo and to the east
        over the plains...making the storm equal to the costliest
        windstorm ever...which occurred in Boulder on January 17...1982.
        In metro Denver...several homes were damaged as shingles were
        blown off roofs.  Large pieces of a roof torn off a strip
        mall in Lakewood damaged several cars in a parking lot.  Most
        of the damage to homes consisted of broken fences...awnings...
        doors...and windows.  Scores of automobiles suffered broken
        or cracked windshields and paint damage from flying debris.
        Multiple accidents were triggered as several tractor-trailer
        rigs were blown on their sides by the strong cross-winds.
        Blowing dust and dirt caused near zero visibilities at
        times.  Both I-25 and I-76 were closed north and northeast
        of Denver.  State Highway 93 was closed between Golden and
        Boulder.  Several trees...power poles...and power lines were
        downed...causing a number of outages as well as sparking a
        few small grass fires.  Highest wind gusts reached 112 mph
        atop Niwot Ridge near the Continental Divide west of
        Boulder...102 mph at Wondervu...100 mph at the National Center
        for Atmospheric Research Mesa Lab in Boulder...98 mph at the
        National Wind Technology Center near Broomfield...96 mph on
        Rocky Flats...92 mph at Jefferson County Airport near
        Broomfield and on the University of Colorado campus in
        Boulder...and 90 mph at Highlands Ranch in southwest metro
        Denver.  Winds gusted to 48 mph at Denver International
        Airport.
9     In 1950...strong southwest winds gusting to 58 mph reduced the
        visibility to 1 mile in blowing dust at Stapleton Airport.
        Scattered minor wind damage...consisting of falling tree
        branches and damage to signs...occurred across metro Denver.
      In 1989...6 to 12 inches of snow fell at many locations in the
        Front Range foothills.  Boulder received 6 to 8 inches.
        Five inches (5.0 inches) of snow fell at Stapleton
        International Airport...causing 2 hour flight delays.
        I-25 south of Denver was closed for 4 hours due to a 100-
        car traffic pileup.  North winds gusted to 33 mph at
        Stapleton International Airport where the maximum snow
        depth on the ground was only 3 inches due to melting.
9-10  In 1900...rain changed to heavy snow and totaled 6.8 inches
        in downtown Denver overnight.  A thunderstorm occurred on
        the 9th.  North winds were sustained to 32 mph with

        winds were sustained to 21 mph with gusts to 22 mph on
         the 9th.
      In 1944...from the 9th to the 10th...7.0 inches of snow fell
        on downtown Denver. Northeast winds were sustained to 24
        mph on the 9th.
      In 1977...the two warmest days of the month resulted in two
        temperature records being set.  High temperature of 81
        degrees on the 9th set a new record maximum for the date.
        High temperature of 80 degrees on the 10th equaled the
        record maximum for the date.  The unusually warm weather
        for so early in April produced a late afternoon
        thunderstorm on the 10th.
      In 1993...from the 9th to the 10th...strong downslope winds
        occurred along the Front Range.  While the strongest winds

        Broomfield.  Northwest winds gusted to 39 mph at Stapleton
        International Airport.
      In 2004...from the 9th to the 10th...a spring storm brought

      In 2008...from the 9th to the 10th...a very moist storm brought
        heavy snow to parts of the Front Range Foothills.  Storm
        totals included: 12.5 inches at Aspen Springs...11 inches
        just southwest of Conifer; with 10.5 inches near Central
        City and 6 miles southwest of Evergreen.  Lesser amounts of
        5 to 9 inches were observed elsewhere.  North winds

        to the Kansas border.  Rain changed to snow on the 9th...and
        snow continued through the 11th.  Snowfall totaled 5.7
        inches at Stapleton International Airport...but maximum
        snow depth on the ground was only 3 inches on the 10th due
        to melting.  East winds gusted to 26 mph on the 9th.
      In 1995...a major spring storm dumped 8 to 16 inches of snow
        in the foothills west of Denver.  Snowfall totaled 8.3
        inches at the site of the former Stapleton International
        Airport...but most of the snow melted as it fell with the
        maximum snow depth on the ground of only 2 inches.  Five-to
        6-inch snow accumulations occurred over southern portions
        of metro Denver and eastward onto the plains.  Northeast
        winds gusted to 36 mph at Denver International Airport on
