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

10-13 In 2014...an Arctic cold front associated with a strong storm
        system over the northern Rockies blasted into northeastern
        Colorado.  The temperature in Denver plummeted from the high
        of 64 degrees at 4:37 pm to 34 degrees by 5:53 pm.  The
        temperatures continued to fall and dropped into the teens
        by early evening.  The Arctic airmass remained entrenched
        over the region...with the high temperatures failing to reach
        the teens from the 11th through the 13th.  This was the first
        time since records have been taken in Denver...dating back to
        1872...that there were three consecutive days with the
        maximum temperatures remained below 20 degrees in the month
        of November.  In addition to the frigid temperatures...0.1
        inch of snowfall was observed on 11th at Denver International
        Airport...which marked the first measureable snowfall for the
        season. An additional 2.2 inches of snowfall was measured on
        the 12th.  Several temperature records were broken.  A
        record low max of 16 degrees on the 11th broke the previous
        record of 19 set back in 1916.  A record low max of 6 degrees
        on the 12th broke the previous record of 9 degrees...also set
        in 1916.  The record low of -13 on the 12th...shattered the
        previous record of -4 degrees set back in 1872.  Even more
        impressive...the record low of -14 degrees on the 13th broke
        the previous record of -3 degrees set back in 1916.
11-14 In 1970...heavy snowfall totaled 7.2 inches at Stapleton
        International Airport where northeast winds gusted
        to 22 mph on the 12th and 14th.  Most of the snow...
        4.2 inches...fell on the 12th.
12-13 In 1961...heavy snowfall totaled 5.6 inches at Stapleton
        Airport.  East-northeast winds gusted to only 20 mph.
      In 2011...hurricane force winds...up to 115 mph...downed trees
        in and power lines across the Front Range Mountains and
        Foothills. Scattered outages were reported in Gilpin
        County.  In Boulder...a woman received minor injuries when
        she was struck in the head by a falling tree limb. Three
        women near Georgetown received minor injuries when they
        were pelted by glass shards after a barrage of wind driven
        rocks and dirt shattered their windshield. Peak wind gusts
        included: 109 mph...6 miles north-northwest of Berthoud
        Pass; 101 mph atop Kenosha Pass...100 mph...2 miles south-
        southwest of Loveland Pass; 99 mph...7 miles west-northwest
        of Berthoud; 92 mph at Blackhawk; 90 mph...3 miles south-
        southwest of Boulder; 87 mph...2 miles west-northwest of
        Aspen Springs and at Pickle Gulch; 84 mph at Loveland Pass
        and Lyons; 82 mph at the National Wind Technology Center;
        80 mph at Dumont and 78 mph near Rollinsville and Ward.
        At Denver International Airport...west winds gusted to
        52 mph on the 12th.
12-15 In 1909...light snowfall totaled 6.7 inches in downtown
        Denver over the 4 days.  This was the first measurable
        snowfall of the season.  Northeast winds were sustained
        to 15 mph on the 12th.
13    In 1951...northwest wind gusts to 50 mph were recorded at
        Stapleton Airport.
      In 1983...winds gusted to around 60 mph in and near the
        foothills.  There were scattered power outages and a few
        broken windows across metro Denver.  The strong winds did
        10 thousand dollars in damage to awnings at the Brown Palace
        Hotel in downtown Denver.  West winds gusted to 46 mph at
        Stapleton International Airport.
13-14 In 1925...heavy post-frontal snowfall totaled 6.4 inches

      In 1974...northwest winds gusted to 52 mph at Stapleton
        International Airport...warming the temperature to 60
        degrees shortly after midnight on the 13th.  A cold front
        cooled temperatures into the 20`s by late morning and
        produced snowfall of 3.7 inches.  The low temperature
        dipped to 14 degrees on the 14th.
      In 1993...an upper level low pressure system combined with a
        weak but moist upslope flow to produce heavy snow across
        metro Denver.  Snowfall amounts averaged 6 to 8 inches with
        up to 16 inches in the foothills at the Eldora Ski Area.
        Snowfall totaled 6.0 inches at Stapleton International
        Airport where north winds gusted to only 20 mph on the
        14th.  Most of the snow fell on the 14th.
      In 1994...heavy snow developed rapidly along the Front Range
        urban corridor with the heaviest snow over northwest metro
        Denver.  Sixteen to 18 inches of snow fell in Boulder...
        Lafayette...and Louisville.  This was the second heavy
        snowfall over northwest metro Denver in 10 days.  Eleven
        to 14 inches of snow were measured from Longmont southward
        into Aurora.  Snowfall totaled 12.1 inches at Stapleton
        International Airport where northeast winds gusted to 29
