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

11-14 In 1997...cold Arctic air plunged temperatures below zero
        across metro Denver.  The temperature was below zero for
        60 consecutive hours from the afternoon on the 11th to
        around daybreak on the 14th.  The high temperature of only
        1 degree below zero on the 12th equaled the record low
        maximum for the date last set in 1963.  The low temperature
        dipped to 14 degrees below zero on the 12th.
13-14 In 1960...snowfall totaled only 4.4 inches and northeast winds
        gusted to 28 mph at Stapleton Airport...while over southeast
        Colorado a near blizzard closed roads with drifts 3 to 6
        feet deep.
13-16 In 1888...a cold air mass settled over the city and caused
        temperatures to plunge well below zero on four consecutive
        days...but only one temperature record was set.  Minimum
        temperatures dipped to 4 degrees below zero on the 13th...
        19 degrees below zero on the 14th...20 degrees below zero
        on the 15th...and 11 degrees below zero on the 16th.  The
        maximum temperature of only 4 degrees below zero on the
        14th was a record low maximum for the date.  North winds
        were sustained to 30 mph on the 13th.
14    In 1873...winds were brisk all day.  After sunset...northeast
        sustained winds produced a perfect gale...behind an
        apparent cold front.
      In 1875...the temperature remained below zero all day with
        a general northeast wind.  At 9:00 PM the temperature was
        1 degree above zero which was the official high for the
        day.  The wind suddenly veered to the southwest and the
        temperature climbed 19 degrees in 15 minutes...7 more
        degrees in the next 5 minutes...and by 9:30 PM had risen
        to 36 degrees.  By 9:35 PM the temperature had reached 40
        degrees...a rise of 48 degrees in one hour and 39 degrees
        in half an hour.  The sudden rise in temperature could be
        attributed to a receding Arctic air mass and downsloping
        surface winds.
      In 1906...the temperature climbed to a high of 56 degrees
        before an apparent cold front produced northeast winds
        sustained to 40 mph and a trace of snow in the afternoon.
      In 1921...west winds were sustained to 44 mph with gusts to
        46 mph.  The downslope winds warmed the temperature to a
        high of 49 degrees.
      In 1967...3.7 inches of snow fell at Stapleton International
        Airport with 7.7 inches measured in Boulder.
      In 1982...strong chinook winds buffeted Boulder...tearing the
        roof off a small apartment building.  A gust to 88 mph was
        measured in Lakewood.  Wind gusts of 60 to 80 mph were
        common along the foothills from Denver north to Fort
        Collins.  Four people sustained minor injuries...mostly from
        flying glass.  At least one person was knocked down by the
        winds.  Several tractor trailer rigs were blown off I-70
        near Golden...and numerous camper shells were blown off
        pick-up trucks.
14-15 In 1908...heavy post-frontal snowfall totaled 6.5 inches
        overnight.  North winds were sustained to 32 mph.  The
        temperature dropped 41 degrees in 24 hours from a reading
        of 48 degrees at 8:00 PM on the 14th to only 7 degrees at
        8:00 PM on the 15th.
      In 1950...strong winds occurred in Boulder and Louisville.
        Winds in excess of 60 mph were recorded at Valmont.  Minor
        damage was reported.  Southwest winds gusted to 50 mph
        at Stapleton Airport.
      In 1959...a total of 5.5 inches of snow fell at Stapleton
      In 1992...snow spread from the mountains across metro Denver.
        The heaviest snow was across the northern portion of the
        area where 7 inches fell at Thornton.  At Stapleton
        International Airport...only 3.4 inches of snowfall were
        recorded and northeast winds gusting to 37 mph caused
        some blowing snow on the 14th.
      In 1999...high winds howled across metro Denver.  In Commerce
        City...strong winds toppled 3 utility poles resulting in a
        power outage to 600 homes.  High wind reports included:
        108 mph at Wondervu...80 mph at the Hiwan Golf Course in
        Evergreen...76 mph at Aspen Springs...75 mph at the Jefferson
        County Airport near Broomfield...74 mph in Boulder...and 70
        mph at Georgetown.  West to northwest winds gusted to 48
        mph...the highest wind gust of the month...and warmed the
        temperature to a high of 60 degrees at Denver International
        Airport on the 15th.
14-21 In 1930...a protracted cold spell occurred when low temperatures
        plunged below zero on 8 consecutive days.  The coldest low
        temperatures of 20 degrees below zero on the 17th and 19
        degrees below zero on the 16th were record minimums for
        the dates.  High temperatures during the period ranged from
        18 on the 18th to zero on the 20th.  Two degrees on the
        15th was a record low maximum temperature for the date.
