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

2-17  In 1939...more than 2 weeks of unseasonably warm weather
        made the month the 3rd warmest on record.  Seven daily
        temperature records were set...including the all time
        record high temperature for the month of 79 degrees on
        the 5th.  Daytime highs were balmy with 14 days in the
        60`s and 70`s.  Low temperatures dipped to freezing or
        below on only 5 days.  The period was dry with only a
        trace of snow on the 12th.
3-15  In 1972...a protracted cold spell held an icy grip on metro
        Denver when maximum temperatures never reached above
        freezing for 10 consecutive days from the 3rd through
        the 12th and minimum temperatures dipped below zero on
        eleven consecutive days from the 5th through the 15th.
        Daily low temperature records were set with 15 degrees
        below zero on the 5th...17 degrees below zero on the 6th...
        and 18 degrees below zero on the 10th.  Daily record low
        maximum readings were set with 3 degrees on the 6th and
        6 degrees on the 9th.  The very cold temperatures were
        caused by 3 to 5 inches of snow cover and a Canadian air
        mass.
4-6   In 1960...heavy snowfall totaled 12.0 inches over the 3 days
        with 5.1 inches on the 4th...5.2 inches on the 5th...and
        1.7 inches on the 6th.  Rain changed to snow early on the
        4th and ended by early afternoon.  Snow started again early
        on the 5th and continued through midday on the 6th.  West
        northwest winds gusted to 30 mph on the 4th.  Post cold
        frontal temperatures cooled from a high of 38 degrees on
        the 4th to a low of 7 degrees below zero on the 6th.
5-6   In 1883...a major snow storm hit the city.  Heavy snow fell
        from 10:00 AM on the 5th to 7:30 AM on the 6th.  The amount
        of snowfall was not recorded...but precipitation from melted
        snow totaled 1.75 inches...which would give an estimated
        snowfall of nearly 18 inches.  Temperatures during the
        storm were in the 30`s...so some of the snow may have melted
        as it fell.  However...railroads were blocked and telegraph
        lines were downed in all directions.  Telephone wires and
        poles were nearly all broken down.  The company manager
        estimated the damage at 30 thousand dollars.  Northeast
        winds were sustained to 24 mph in the city.
      In 1892...heavy snow totaled 6.2 inches in downtown Denver.
        Most of the snow...6.0 inches...fell on the 6th.
      In 2001...high winds developed in the foothills northwest of
        Denver.  Winds gusted to 74 mph at Aspen Springs.  West-
        northwest winds gusted to 35 mph at Denver International
        Airport...where the temperature warmed to a high of 55
        degrees on the 6th.
5-7   In 1978...a major storm dumped heavy snow across metro Denver.
        At Stapleton International Airport...snowfall totaled 8.5
        inches...northeast winds gusted to 46 mph...and temperatures
        plunged from a high of 49 degrees on the 5th to a low of
        only 6 degrees on the 6th.  Maximum temperature of 6 degrees
        on the 7th was a new daily record low maximum reading.  Most
        of the snow...6.7 inches...fell on the 5th.
5-8   In 1983...high winds occurred in and near the foothills each
        day.  Wind gusts to 63 mph were registered in Golden Gate
        Canyon on the evening of the 5th.  On the evening of the
        6th...winds knocked down trees...snapped power lines...and blew
        out windows across metro Denver.  Gusts were clocked to 102
        mph in southwest metro Denver...while wind gusts to 38 mph
        were recorded at Stapleton International Airport.  On the
        7th...winds overturned a tractor trailer near Castle Rock.
        After midnight on the 8th...gusts to 97 mph were reported in
        southeast Boulder.  Wind speeds of 60 to 70 mph were
        reported in other parts of metro Denver.
6     In 1939...high temperature of 73 degrees was a record maximum
        for the date.  Low temperature of 44 degrees was a record
        high minimum for the date.
      In 1967...strong west winds produced blowing dust at Stapleton
        International Airport where a wind gust to 55 mph was
        recorded.  A heavy windstorm caused minor damage in Boulder.
        In Denver...some structural panels were blown from a building...
        and the screen of an outdoor theater was severely damaged.
        There were unofficial reports of wind gusts to 75 mph in
        metro Denver.
      In 1977...wind gusting to 85 mph raked the foothills from
        Boulder to Morrison.  A few houses under construction
        were blown down.  Northwest winds gusted to 39 mph at
        Stapleton International Airport.
      In 1991...high in the atmosphere...a volcanic ash cloud was
        clearly visible in the direction of the sun during the
        late morning and early afternoon.
6-7   In 1953...high winds buffeted the eastern foothills.  Wind
        gusts to 80 mph occurred on Lookout Mountain.  In Denver
        winds gusted to 65 mph.  Damage in Boulder totaled 15
        hundred dollars.
