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

7-9   In 1913...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...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

        inches near Arapahoe Park; with 6.5 inches at Denver
        International Airport.
8-10  In 1999...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

        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
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.

        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...strong downslope winds occurred along the Front
        Range.  While the strongest winds were in the foothills

        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
