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

10-11 In 1986...from the 10th to the 11th...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...from the 10th to the 12th...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
        gust.
      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 1901...an 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 on the 12th.  This was the first snowfall of the
        season. Total precipitation was 0.32 inch.
11-13 In 1892...from the 11th to the 13th...apparent post-frontal
        rainfall totaled 3.33 inches in downtown Denver over the
        3-day period.  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.
