...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
8-12  In 1932...the second longest sub-zero period on record in
        Denver occurred.  The temperature fell below zero shortly
        after 1:00 PM on the 8th and remained below zero for 92
        hours until 9:00 AM on the 12th.  The lowest temperature
        recorded during this period was 13 degrees below zero on
        both the 9th and 11th.  That temperature on the 11th was
        a record low for the date.  High temperatures of 4 on the
        8th...5 below zero on the 9th...1 below zero on the 10th...
        and 6 below zero on the 11th were record low maximum
        temperatures for those dates.  Light north winds at 5 to
        10 mph were accompanied by occasional light snow...which
        totaled only 2.2 inches.
9-13  In 1961...cold arctic air produced a protracted cold period.
        The temperature plunged to 16 degrees below zero on the
        10th...establishing a new record for the date and the
        coldest reading since 25 degrees below zero on February 1...
        1951.  Low temperatures dipped below zero on 5 consecutive
        days with 9 degrees below zero on the 9th...16 below on the
        10th...10 below on the 11th...and 12 below on both the 12th
        and 13th.  High temperatures reached only 3 degrees on the
        10th and 6 degrees on the 11th.
11-12 In 1903...a sharp cold front on the 11th plunged temperatures
        from a high of 59 degrees to a low of 15 degrees...produced
        northeast winds sustained to 42 mph along with gusts as
        high as 60 mph...and produced 1.3 inches of snow overnight.
        The high temperature on the 12th was only 25 degrees.
      In 1968...strong winds buffeted the eastern foothills and
        plains and caused light...but widespread property damage.

        gusted to 52 mph at Stapleton International Airport.
11-13 In 1940...5.4 inches of snow fell across downtown Denver.
        This was the only snowfall of the month.  Temperatures
        were quite cold on the 13th with a high of 6 degrees and
        a low of 2 degrees below zero.
      In 1984...up to 6 inches of new snow fell over metro Denver...
        hampering flight operations at Stapleton International
        Airport where snowfall totaled 3.8 inches and east winds
        gusted to 25 mph on the 11th.
12    In 1937...a thunderstorm...rare in December...produced 0.09
        inch of rain in advance of a cold front.
      In 1973...high winds occurred across all of metro Denver
        with the foothills area being hit the hardest.  A wind gust
        to 120 mph was recorded in Boulder where damage to homes...fences...and buildings totaled 100
        thousand dollars.  A northwest wind gust to 66 mph occurred
        at Stapleton International Airport.
      In 1988...strong winds were recorded in Boulder.  Peak wind
        gusts reached 70 mph at Table Mesa and 61 mph in east
        Boulder.  West winds gusted to 31 mph at Stapleton
        International Airport.
12-13 In 1916...snowfall totaled 5.7 inches in downtown Denver.
        Northeast winds were sustained to 27 mph with gusts to
        28 mph on the 12th.
      In upslope snowstorm whitened metro Denver.  While
        snowfall totaled only 4.1 inches at Stapleton International
        Airport...7 inches of new snow fell in Morrison...with 12
        inches measured in Castle Rock.  North winds gusted to
        23 mph at Stapleton International Airport on the 13th.
      In 1995...strong winds gusting to nearly 100 mph whipped
        across the foothills west of Denver.  The strongest wind
        gusts included 98 mph atop Squaw Mountain and 75 mph at
        the Eldora Ski Area.  West-northwest winds gusted to 41
        mph at Denver International Airport on the 13th.
12-15 In 1921...downslope chinook winds produced warm temperatures
        in the city...which resulted in 4 temperature records.
        High temperatures of 72 degrees on the 13th and 68 degrees
        on the 15th were record maximums for the dates.  Low
        temperatures of 47 degrees on both the 12th and 13th were
        record high minimums for the dates.  West winds were
        sustained to 38 mph on the 12th and to 25 mph on the
