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

23-24 In 1887...the first measurable snowfall of the season totaled
        3.1 inches.  North winds to 20 mph were recorded on the
        23rd.  This was the only measurable snow of the month.
      In snowfall from the late evening of the
        23rd continued through the late afternoon of the 24th and
        totaled 6.2 inches.  Southeast winds were sustained to 25
        mph with gusts to 26 mph on the 23rd.  Temperatures cooled
        from a high of 68 degrees on the 23rd to a low of 25
        degrees on the 24th...the coldest reading of the month that
        year.  Many trees that had not shed their leaves became
        heavily laden by the wet snow.  Many branches were broken...
        and a few trees toppled under the weight of the snow.  The
        landscape became one of rare beauty.
24    In 1956...southwest winds gusted to 56 mph and produced some
        blowing dust at Stapleton Airport.  A cold front produced
        a thunderstorm with 1/8 inch hail.  Rain later changed to
        snow.  Precipitation totaled only 0.11 inch and snowfall
        only 0.3 inch.
      In 1973...strong winds raked the eastern foothills...causing
        damage in Boulder and Jefferson counties.  The heaviest
        damage occurred in the Boulder area where 20 to 25 mobile
        homes were hit...some power and telephone lines were blown
        down...and a store was damaged.  A wind gust to 76 mph was
        recorded in Boulder at the National Bureau of Standards.
        Northwest winds gusted to 46 mph at Stapleton International
24-25 In 1921...rainfall totaled 0.35 inch overnight behind an
        apparent cold front.  North winds were sustained to 40 mph
        with gusts to 46 mph on the 25th.  Temperatures plunged
        from a high of 73 degrees on the 24th to a low of 39
        degrees on the 25th.
      In 1923...rain overnight changed to snow during the morning.
        The heavy snowfall accumulated to 12.0 inches before ending
        on the morning of the 25th.  Post-frontal north winds were
        sustained to 22 mph with gusts to 23 mph on the 24th.
      In of the worst and deadliest blizzards of the
        decade developed over eastern Colorado as deep east to
        northeast flow associated with a vigorous upper level low
        pressure system over the Four Corners...combined with a
        strong Arctic air mass over the central Great Plains.
        Snowfall totals across metro Denver ranged from 14 to 31
        inches.  The heaviest snowfall occurred in the foothills
        west and southwest of Denver where 2 to 4 feet of snow
        were measured.  Sustained winds to 40 mph with gusts as
        high as 60 mph produced zero visibilities and extremely
        cold wind chill temperatures from 25 below to 40 below
        zero.  Winds whipped the snow into drifts 4 to 10 feet
        deep.  Several major and interstate highways were closed
        as travel became impossible.  Red Cross shelters were set
        up for hundreds of travelers who became stranded when
        they had to abandon their vehicles.  Four people died in
        northeastern Colorado as a result of the blizzard.  None of
        the deaths were in metro Denver.  At Denver International
        Airport...4 thousand travelers were stranded when the airport
        was forced to shut down.  At least 120 cars were abandoned
        along Pena Blvd....the only arterial leading into and out
        of DIA.  The blizzard cost air carriers at least 20 million
        dollars.  Thousands of cattle died in the storm over
        northeastern Colorado...resulting in losses totaling 1.5
        million dollars.  Some of the more impressive snowfall
        totals included:  51 inches at Coal Creek Canyon; 48
        inches at Silver Spruce Ranch...near Ward; 42 inches at the foothills southwest of Denver; 37 inches
        at Sedalia; 35 inches at Aspen Springs and Conifer in the
        foothills west of Denver; 31 inches at Eldorado Springs...
        southeast Aurora...and Englewood; and 30 inches on Table Mesa
        in Boulder.  Snowfall totaled 21.9 inches at the site of
        the former Stapleton International Airport...setting a new
        24-hour snowfall record of 19.1 inches for the month.
        Snowfall totaled only 14 inches at Denver International
        Airport where north winds gusted to 39 mph on the 24th.
        High temperature of only 21 degrees on the 25th equaled
        the record low maximum for the date first set in 1873.
        Low temperature of only 3 degrees on the 26th set a new
        record minimum for the date.
