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

28-31 In 1929...rain changed to snow on the afternoon of the 28th
        and continued until midday on the 30th followed by
        intermittent light snow which continued through the 31st.
        Snowfall over the four days totaled 16.2 inches in the
        city.  Most of the snow...8.5 inches...fell on the 29th
        with 6.1 inches on the 30th.  Temperatures hovered in
        20`s during most of the storm.
29-31 In 1889...the first snowfall of the season totaled 14.0 inches
        over the three days in downtown Denver.  Snowfall was 8.0
        inches on the 29th and 5.0 inches on the 31st.  North to
        northeast winds gusted to 30 mph on the 29th.
      In 1950...a warm spell resulted in five daily temperature
        records.  Record highs of 84...80...and 79 degrees occurred
        on the 29th...30th...and 31st...respectively.  Low temperature
        of 49 degrees on the 30th was the record high minimum for
        the date.
      In 1991...the second surge of cold Arctic air in a matter of
        days plunged metro Denver into the deep freeze.  While
        low temperatures remained above zero...high temperatures
        were only in the 20`s.  Three temperature records were set:
        record lows of 7 degrees on the 30th and 10 degrees on the
        31st and a record low maximum of only 21 degrees on the
        30th.  Snowfall was light with only 1.9 inches recorded at
        Stapleton International Airport where east winds gusted
        to 23 mph.
      In 2002...snowfall totaled 4.3 inches at the site of the former
        Stapleton International Airport.  North winds gusted to 32
        mph on the 29th behind a cold front...which plunged
        temperatures well below seasonal normals.  High temperatures
        of 18 degrees on the 30th and 19 degrees on the 31st were
        record low maximums for each date.  Low temperatures dipped
        to 12 degrees on the 30th and 15 degrees on the 31st.
29-1  In 1972...heavy snowfall totaled 15.5 inches at Stapleton
        International Airport.  However...the heaviest snow occurred
        on Halloween night when 7 inches fell on trick-or-treaters
        during a short 3-hour period.  I-25 was closed south of
        Denver.  North winds gusting to 29 mph caused some blowing
        snow on the 1st.  The snow started late on the 29th and
        ended during the mid afternoon on the 1st.  The greatest
        snow depth on the ground at Stapleton International Airport
        was 13 inches on the 1st.
31    In 1997...high winds buffeted the foothills and adjacent
        areas of metro Denver.  West winds gusted to 70 mph in
        Broomfield and to 40 mph at Denver International Airport.
        The strongest winds occurred in the mountains west of
        Denver and in the foothills north of Denver.
      In 2001...high winds developed in the foothills.  Peak wind
        gusts were measured to 74 mph at the National Center for
        Atmospheric Research on the mesa in Boulder and to 72 mph
        near Rollinsville.  West winds gusting as high as 53 mph
        warmed the temperature to a high of 71 degrees at Denver
        International Airport.
31-1  In 1951...6.4 inches of snowfall were measured at Stapleton
      In 1989...a Halloween storm dropped 3 to 6 inches of snow on
        metro Denver with the adjacent foothills receiving 5 to
        10 inches.  Snowfall totaled 4.5 inches at Stapleton
        International Airport...where north winds gusted to 31 mph
        on the 31st.  Most of the snow fell on the evening of the
        31st...but the storm left icy streets throughout metro Denver
        on the morning of the 1st...making it a "spooky" commute for
        many motorists.
      In 2004...heavy snow fell in and near the foothills of Jefferson
        and Douglas counties.  Storm total snowfall included:  14.5
        inches in Aspen Park...10 inches at Roxborough State Park and
        and near Sedalia...8 inches near Bergen Park...and 7 inches in
        Highlands Ranch.  Snowfall totaled only 3.2 inches in the
        Denver Stapleton area.  Post-frontal northeast winds gusted
        to 41 mph at Denver International Airport.
