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

10-11 In 1986...the first significant snowstorm of the season
        produced 2 to 5 inches of snow over metro Denver with 5
        to 10 inches in the foothills west of Denver.  Wondervu
        recorded the most snow from the storm...13 inches.  The
        heavy wet snow caused numerous power outages.  The storm
        was accompanied by strong north winds with gusts to 41 mph
        recorded on the 10th.  The first snowfall of the season
        totaled 3.1 inches at Stapleton International Airport with
        only one inch on the ground due to melting.  The strong
        cold front accompanying the storm cooled the temperature
        from a high of 73 degrees on the 10th to a high of only
        33 degrees on the 11th...which was a record low maximum
        for the date.
10-12 In 1969...the second heavy snowstorm in less than a week
        dumped nearly a foot of snow across metro Denver and
        plunged the area into extremely cold temperatures for so
        early in the season.  Snowfall totaled 11.0 inches at
        Stapleton International Airport.  North winds gusting to
        26 mph produced drifts up to 2 feet deep.  Temperatures
        dipped from a high of 52 degrees on the 10th to a record
        low for the date of 10 degrees on the 12th.  There was
        additional damage to trees and power and telephone lines
        from heavy snow accumulations and icing.  Travel was
        restricted or blocked by drifting snow in both the
        mountains and on the plains east of Denver.
11    In 1997...damaging winds ahead of an approaching storm system
        developed in the foothills and spread across metro Denver.
        Winds gusted to 88 mph at Conifer...71 mph at the National
        Center for Atmospheric Research on the mesa in Boulder...
        and 53 mph at Denver International Airport.  Several
        trees and street signs were blown down with scattered
        power outages reported throughout metro Denver.  In
        Arvada...a car window was blown out by a strong wind
      In 2013...high winds occurred in and near the Front Range
        Foothills. Peak gusts included: 85 mph at Rooney Road...
        84 mph...2 miles south of Marshall; 82 mph at Rocky Flats
        National Wind Technology Center and Wondervu; 79 mph at
        the Mesa Lab at NCAR and 75 mph...3 miles south-southwest
        of Boulder; 73 mph in Superior and 68 mph in Golden. The
        wind downed trees and power lines. As a result...scattered
        electrical outages affected 20000 Xcel Energy customers
        through the morning hours. The main outages affected the
        cities of Boulder...Golden and Lakewood. Smaller outages
        were reported in areas of Gold Hill...Ward...Westminster
        and Wheat Ridge.
11-12 In apparent cold front produced northeast winds
        sustained to 42 mph with gusts to 48 mph on the 11th.
        General rain changed to snow overnight and totaled 2.0
        inches.  This was the first snowfall of the season.
        Total precipitation was 0.32 inch.
11-13 In 1892...apparent post-frontal rainfall totaled 3.33
        inches in downtown Denver over the 3 days.  A trace
        of snow on the 12th melted as it fell.  Rainfall of
        2.58 inches on the 12th into the 13th was the greatest
        24-hour precipitation ever recorded during the month of
        October.  Northwest winds were sustained to 48 mph with
        gusts as high as 55 mph on the 12th.
