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

14-18 In 1964...the first measurable snowfall of the season
        totaled 6.0 inches at Stapleton International Airport
        where northeast winds gusted to 32 mph on the 14th.
        Most of the snow...4.2 inches...fell on the 14th.  This
        was the only measurable snow of the month.
15-17 In 1991...a strong winter storm dumped heavy snow over metro
        Denver.  Snowfall amounts totaled 15 inches at Castle Rock
        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.
16-17 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
        wind gusts included:  68 mph atop Niwot Ridge...62 mph at
        Loveland Pass...55 mph near Blackhawk and 52 mph at Berthoud
        Pass.
16-18 In 1921...heavy snowfall totaled 6.5 inches over downtown
        Denver.  This was the only measurable snow of the month.
        East winds were sustained to 14 mph on the 17th.
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
        Rocky Flats south of Boulder.  West winds gusted to 49 mph
        at Stapleton International Airport.
      In 2000...snow fell in the foothills west of Denver...mainly
        south of the I-70 corridor.  Snowfall totals included:
        8.5 inches...7 miles south of Tiny Town; 6 inches at
        Genesee; and 5 inches...11 miles southwest of Morrison.
        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
        of Evergreen; 7.5 inches near Conifer...with 4 to 7 inches
        elsewhere. At Denver International Airport...1.7 inches of
        snowfall was observed.
17-18 In 1869...the heaviest wind storm in 5 or 6 years raked the
        eastern foothills including Boulder...Denver...Georgetown...
        and Golden.  Some hundreds of dollars in damage occurred
        in Boulder.
      In 2022...heavy snow developed in and near the foothills of
        Boulder and northern Jefferson counties...where storm totals
        ranged from 6 to 12 inches of snowfall. Periods of light to
        moderate snowfall occurred elsewhere.  In Denver and the
        surrounding suburbs...storm totals included:  12 inches near
        Golden and west Boulder...10.9 inches...3.5 miles west-northwest
        of Arvada; 8 inches in Lakewood...6 inches at Ken Caryl and Wheat
        Ridge...with 3.8 inches at Denver International Airport.
