        front...which produced only 0.2 inch of snowfall at
        Stapleton International Airport.
7     In 1958...a strong cold front produced northeast wind gusts
        to 52 mph at Stapleton Airport where some blowing dust
        was observed.
      In 1980...chinook winds at sustained speeds of 40 mph were
        recorded with a peak gust to 71 mph measured at Wondervu
        southwest of Boulder.  West winds gusted to 25 mph at
        Stapleton International Airport.
      In 1989...strong winds buffeted many foothills areas.  Wind

        Longmont.  Northwest winds gusted to 43 mph at Stapleton
        International Airport.
      In 1996...wind gusts to 75 mph were recorded at Golden Gate
        Canyon and at the Rocky Flats Environmental Test Facility
        northwest of Denver.  Northwest winds gusted to 40 mph at
        Denver International Airport.
      In 1998...upslope conditions...coupled with a moist and
        unstable air mass...allowed heavy snow to develop
        in the foothills west of Denver.  Snowfall generally
        ranged from 4 to 6 inches...but 7 inches were measured
        4 miles south of Evergreen.  Only 1.2 inches of snow
        fell at the site of the former Stapleton International

        minor damage.
8     In 1896...southwest chinook winds sustained to 42 mph with
        gusts as high as 46 mph warmed the temperature to a high
        of 53 degrees.
      In 1977 near-blizzard conditions in blowing snow caused the
        closure of I-70 to the west of Denver in Clear Creek Canyon
        and east of Denver to Limon.  Northeast wind gusts to 46 mph
        were recorded at Stapleton International Airport where
        snowfall totaled only 1.1 inches.

        northwest winds gusted to 32 mph at Denver International
        Airport.
      In 2006...the temperature in Denver climbed to a high of 80
        degrees.  This was the first time the temperature had ever
        exceeded the 70`s in November since records began in 1872.
        This new all-time record maximum temperature for the month
        of November was also a new daily record and the highest
        temperature ever recorded so late in the season.
8-9   In 1897...west winds were sustained to 45 mph with gusts
        as high as 50 mph in the city.

        the 8th.
      In 1975...heavy snowfall hit metro Denver.  Snowfall at
        Stapleton International Airport totaled 8.0 inches and
        east winds gusted to 21 mph.  Power outages caused by the
        storm affected over 10 thousand people in metro Denver.  In
        the foothills west of Denver...10 to 15 inches of snow fell.
        The storm produced the greatest 24-hour precipitation...1.29
        inches...ever recorded during the month of November in the
        city.
      In 1983...metro Denver received 4 to 8 inches of snow with the
        heaviest amounts near the foothills.  It was the first
        measurable snow of the season in Denver.  Only 1.8 inches of
        snow fell at Stapleton International Airport where north
        winds gusted to 20 mph.
      In 1989...strong winds hit the Front Range.  On the 9th...the

        central Jefferson County where 14 inches were measured
        8 miles west of Conifer.  Other snowfall totals included:
        10 inches at Evergreen and 9 miles northwest of Bergen
        Park; 9 inches at Genesee...Nederland...and near the Chief
        Hosa exit on I-70; and 8 inches in Coal Creek Canyon.  On
        the 9th...snowfall was 2.6 inches at the site of the former
        Stapleton International Airport.  North-northeast winds
        gusted to 30 mph at Denver International Airport on the 9th.
8-10  In 1985...Indian summer came to an abrupt end when a winter
        storm dumped 10 to 18 inches of snow in the Front Range
        foothills and 6 to 10 inches across metro Denver...snarling
        traffic and causing flight delays of up to 3 hours at
        Stapleton International Airport.  The temperature plunged
        from a high of 66 degrees on the 8th to a low of only 13
        degrees on the 9th...after the passage of a vigorous cold
        front with northeast winds gusting to 32 mph.  The
        temperature climbed to only 19 degrees on the 10th...setting
        a record low maximum for the date.  Snowfall totaled 7.3
        inches at Stapleton International Airport with most of the
        snow...7.1 inches...falling on the 9th.
9     In 1939...a trace of snow fell over downtown Denver.  This
        snow...along with a trace of snow on the 2nd...was the only
        snow of the month...ranking it...along with other months...the
        second least snowiest November on record.  Precipitation of
        0.01 inch was the only precipitation of the month...making
        this the second driest November on record.
      In 1944...the first killing frost of the season occurred in
        the city when the low temperature dipped to 35 degrees.
        This is the latest date for a killing frost ever recorded
        in Denver.
      In 1946...heavy snowfall totaled 7.7 inches over downtown
        Denver.  This was the second heavy snowfall in less than
        a week.  Northwest winds were sustained to 26 mph.
      In 1995...strong downslope winds gusted between 50 and 57 mph
        at Erie and Boulder.  West wind gusts to 44 mph were
        recorded at Denver International Airport.
      In 2014...a record high min of 45 degrees...broke the previous
        record of 43 degrees set in 1934...and preceded several days
        of record cold temperatures from the 11th through the 13th.
 10    In 1897...west chinook winds sustained to 51 mph with gusts
        to 60 mph warmed the temperature to a high of 64 degrees.

        Boulder where some damage occurred.
      In 1995...snowfall totaled 6 to 9 inches in the foothills
        west of Denver...while only 2.2 inches of snow fell
        at the site of the former Stapleton International Airport.
        North-northeast winds gusted to 31 mph at Denver
        International Airport.
      In 1998...strong bora winds gusting from 70 to 92 mph coupled
        with blowing snow created whiteout and slick black ice
        conditions at the base of the foothills west of Denver.
        State Highway 93 between Golden and Boulder and C-470...
        near the Morrison interchange were closed for several
        hours due to multiple car accidents.  Dozens of motorists
        were stranded until weather conditions improved.  A small
        motor home was a total loss when it caught fire after
        being blown on its side by strong crosswinds.  A man was
        injured when he was blown off a vehicle while attempting
        to rescue the occupants.  Wind gusts included:  92 mph atop
        Blue Mountain near Coal Creek Canyon...83 mph atop Fritz
        Peak near Rollinsville...and 77 mph at Jefferson County
        Airport near Broomfield.  West winds gusted to 36 mph at
        Denver International Airport.
      In 2000...freezing drizzle was widespread across northeastern
        Colorado with the heaviest amounts near the foothills in
        the evening.  The freezing drizzle made many highways icy
        and slick...which contributed to a number of traffic
        accidents.  Some highways across metro Denver were closed
        at times...including portions of State Highway 119 between
        Boulder and Longmont and U.S. 36 between Westminster and
        Boulder.  State Highway 93 between Boulder and Golden atop
        Rocky Flats became nearly impassable due to a coating of
        ice by late evening.
10-11 In 1911...a strong cold front produced snow and a cold wave.
        The temperature dropped 68 degrees from a high of 66 degrees
        at 12:40 PM on the 10th to a low of 2 degrees below zero at
        7:15 AM on the 11th.  The low temperature of 23 degrees at
        midnight on the 10th was also the high temperature on the
        11th.  Northeast winds were sustained to 42 mph with gusts
        to 51 mph.  Snowfall was only 2.5 inches.
      In 1982...up to 4 inches of snow fell over the higher terrain
        between Denver and Colorado Springs.  Winds gusted to 50
        mph along the foothills.  Rainfall totaled 0.27 inch
        with only 0.1 inch of snow on the 11th at Stapleton
        International Airport where north winds gusted to 39 mph.
        Dense fog with visibilities as low as zero persisted all day
        on the 10th.
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    In 1901...a trace of rain fell in the morning...and a trace of
        snow fell in the afternoon.  This was the only snowfall and
        precipitation for the month...ranking it the driest November
        on record...along with November of 1899 and 1949.  The month
        also ranks as the second least snowiest November...along with
        Novembers in other years.

        gusts to 29 mph.
      In 1919...light snow fell from an apparent clear sky during the
        early afternoon.  The first snow was observed at about 12:40
        PM and continued at least 30 minutes before clouds could be
        seen forming...followed by the sky becoming totally cloudy.
        During this time the temperature fell from 50 degrees at
        noon to only 18 degrees at 100 PM and plunged to 6 degrees
        at 5:45 PM.  A low temperature of 2 degrees was recorded
        overnight.  Northeast winds were sustained to 33 mph with
        gusts to 36 mph between noon and 1:00 PM behind an apparent
