... Today in Metro Denver weather history...

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.
19-21 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
        fell heavily during past night. At 5:43 am it was snowing
        light and continued until 8 am. Wind during snow storm
        gentle and a little west of south... and continued there
        during the remainder of the day. Sky clear after 8 am.
        Very cold weather prevailed all day and night. Thermometer
        at 9:43 PM 14 degrees. Rain gauge and self-registering
        thermometer not in position owing to severe storm last
        week. Barometer falling during the morning and rising
        rapidly at night."
      In 1894... northwest Chinook winds sustained to 40 mph with
        gusts to 45 mph warmed the temperature to a high of 58
        degrees in the city.
      In 1909... steady and very strong winds in Boulder caused
        3 thousand dollars in damage.
      In 1915... Post-frontal northeast winds sustained to 40 mph
        with gusts as high as 42 mph produced only a trace of
        snow. It was windy most of the day.
      In 1923... west winds were sustained to 42 mph with gusts
        to 44 mph before daybreak. The strong winds persisted
        in the city for only about 3 hours.
      In 1993... a wind gust to 72 mph was recorded at Table Mesa in
        southwest Boulder.
      In 1994... winds gusted to 77 mph atop Squaw Mountain west
        of Denver. West winds gusted to 40 mph at Stapleton
        International Airport.
20-21 in 1898... snowfall totaled 4.0 inches in downtown Denver.
        Northeast winds were sustained to 48 mph with gusts as
        high as 60 mph behind an apparent cold front on the 20th...
        when temperatures plunged from a high of 66 degrees to a
        low of 9 degrees. On the 21st the high was only 24 degrees
        and the low was 2 degrees.
      In 1970... a wind gust to 94 mph was recorded at Gold Hill in
        the foothills west of Boulder. Strong winds also swept
        across Metro Denver. Wind gusts reached 59 mph in downtown
        Boulder... while at Stapleton International Airport west-
        northwest winds gusted to 43 mph on the 21st. Damage was
        minor.
      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
        very moist air aloft produced heavy snow across the entire
        state. Snowfall totaled 6.3 inches at Stapleton
        International Airport... where north winds gusted to 23 mph
        on the 20th. Snow was heavier in the foothills... with 14
        inches at Wondervu... 13 inches at Aspen Springs... Conifer...
        Boulder... and Gross Reservoir... 8 inches at Rollinsville...
        and 10 inches at Golden Gate Canyon and Morrison.
      In 2007... a storm system brought moderate to heavy snowfall
        to portions of the urban corridor. Storm totals included:
        7 inches... 3 miles south-southeast of Fort Collins... with 6
        inches in Boulder and at horsetooth Inlet Bay. Elsewhere...
        storm totals ranged from 2 to 5 inches. Snowfall
        totaled 2.0 inches at the site of the former Stapleton
        International Airport.
