      In 1996...around a foot of new snow fell in the foothills
        west of Denver with 3 to 6 inches at lower elevations
        across metro Denver.  Some of the snowfall totals

        and Conifer...14 inches at Morrison and Parker...12 inches in
        southeast Aurora...and 11.6 inches at Stapleton International
        Airport.  Winds were light with the storm.
16    In 1899...a trace of rain fell in the city.  This...together
        with a trace of precipitation on the 21st and 23rd...was the

16-17 In 2010...the combination of heavy snow and strong winds
        produced dangerous driving conditions in the high country.
        Blizzard conditions forced the closure of U.S. Highway 6 at
        Loveland Pass and U.S. Highway 40 at Berthoud Pass.  Blowing
        and drifting snow forced the closure of a 65-mile stretch of
        Interstate 70...west of Idaho Springs.  Peak wind gusts
        included:  68 mph atop Niwot Ridge...55 mph near Blackhawk
        and Gunsight...and 52 mph at Berthoud Pass.  Storm totals in
        the ski areas west of Denver ranged from 12 to 21 inches.
        Northwest winds gusted to 55 mph at Denver International
        Airport on the 16th.
      In 2010...the combination of snow and strong winds produced
        dangerous driving conditions in the mountains west of
        Denver. Near blizzard conditions forced the closure of U.S.
        Highway 6 at Loveland Pass and U.S. Highway 40 at Berthoud
        Pass. Blowing and drifting snow closed a 65-mile stretch of
        Interstate 70...between Idaho Springs and Vail Pass. Peak

17    In 1948...a dry vigorous cold front accompanied by north winds
        gusting to 60 mph produced extensive blowing dust...which
        briefly reduced the visibility to 1/2 mile at Stapleton
        Airport.
      In 1993...a wind gust to 70 mph was recorded atop Squaw
        Mountain near Idaho Springs.
      In 1994...winds gusted to 66 mph in Boulder and to 63 mph on

        Only a trace of snow was recorded at the site of the
        former Stapleton International Airport.
      In 2016...bands of moderate to heavy snow fell along the
        Interstate 70 Corridor as strong fast moving storm system
        moved across Colorado. Wet roads quickly became icy and
        snowpacked. A 20-vehicle crash involving semis kept both
        directions of I-70 closed near Evergreen for a couple of
        hours. Storm totals included:  11.5 inches...4.5 miles
        south-southeast of Idaho Springs; 8 inches...5 miles west

        Ridge...with 3.8 inches at Denver International Airport.
18    In 1872...fresh west winds contributed to the relative
        humidity dipping to zero at 2:43 PM.  The maximum
        temperature was 54 degrees.
      In 1907...heavy snowfall totaled 6.0 inches over downtown
        Denver.  Snow fell all day.  North winds were sustained
        to 19 mph.
      In 1915...northwest winds were sustained to 42 mph with

        gusted to 41 mph at Denver International Airport.
      In 1999...high winds developed in and near the Front Range
        foothills.  The strong winds downed power lines...which
        sparked several small brush fires.  In Broomfield...
        scaffolding was damaged at the Wadsworth Recreation
        Center...while flying rocks broke several windows at a
        local bank building.  Peak wind gusts included:  91 mph
        atop Blue Mountain near Wondervu...88 mph atop the Gamow
        Tower on the University of Colorado campus in Boulder...
        83 mph at Jefferson County Airport...81 mph at the
        National Center for Atmospheric Research Mesa Lab above
        Boulder...and 80 mph at Wondervu.  West-northwest winds
        gusted to 48 mph at Denver International Airport.
18-19 In 1975...snowfall totaled only 5.5 inches and north winds
        gusted to 35 mph causing some blowing snow at Stapleton
        International Airport...while a major blizzard struck
        southeastern Colorado.
      In 1985...4 to 7 inches of snow fell across metro Denver.
        Snowfall totaled 4.4 inches at Stapleton International
        Airport where north winds gusted to 23 mph.

        Ridge.  This second storm brought the 5 day (15th-19th)
        snowfall total at Stapleton International Airport to
        21.1 inches.  The greatest depth of snow on the ground
        was 13 inches on the morning of the 19th.  The adverse
        effects of the two storms were diminished by the lack
        of significant winds.
18-20 In 1930...a major storm dumped a total of 13.6 inches of
        snowfall over downtown Denver.  Most of the snow...9.4
        inches...fell on the 19th when north winds were sustained
        to 23 mph.  This was the only measurable snow of the
        month.  Temperatures hovered in the 20`s and lower 30`s.
      In 1956...an intense winter storm dumped 12.8 inches of
        snowfall on metro Denver.  Strong north-northeast winds
        gusting to 33 mph at Stapleton Airport frequently reduced
        the visibility to 1/2 mile in snow and blowing snow on the
        19th.  Most of the snowfall...10.7 inches...occurred on the
        19th.
19    In 1931...the first measurable snow of the season totaled
        only 1.0 inch in the city.
      In 1977...near-blizzard conditions caused some traffic
        accident injuries across metro Denver.  Only 1.3 inches
        of snow fell at Stapleton International Airport where
        northeast winds gusted to 28 mph.
19-21 In 1979...a heavy snowstorm buried most of Colorado under at
        least a foot of snow.  Snowfall at Stapleton International
        Airport totaled 17.7 inches...the greatest snow depth since
        1946.  Winds to 60 mph produced 5-foot drifts paralyzing
        the city as temperatures hovered in the 20`s.  While small
        airports closed...Stapleton remained open...but with long
        delays that snarled Thanksgiving holiday traffic.  Schools
        and businesses closed and postal deliveries were delayed.
        Almost all major highways leading out of Denver were closed
        to traffic for periods of time on the 20th and 21st.  Most
        of the snow...13.5 inches...fell on the 20th.  At Stapleton
        International Airport...north winds gusted to 35 mph on the
        20th and to 38 mph on the 21st.
20    In 1871...the first official weather observation in Denver...
        was taken by Henry Fenton...Observer Sergeant of the United
        States Army Signal Service at 5:43 AM.  The office was
        located on the 2nd floor of a building at the corner of
        Larimer and G Streets...now 16th Street.  The daily weather
        journal hand written entry for the day follows:  "Snow

      In 1992...a large Canadian air mass moved into the state at
        the same time an upper level storm system approached from
        the west.  The combination of cold air at the surface and
