...This week in metro Denver weather history...

25-31 In 1980...temperatures were unusually warm during the week
        between Christmas and New Year`s.  High temperatures for
        the week ranged from the mid-50`s to the mid-70`s.  Four
        temperature records were set.  Record highs occurred on
        the 26th with 68 degrees...the 27th with 75 degrees...and
        the 30th with 71 degrees.  A record high minimum
        temperature of 41 degrees occurred on the 27th.
30-31 In 1887...heavy snow totaled 6.5 inches in downtown Denver.
        Most of the snow...4.5 inches...fell on the 31st.  North
        winds were sustained to 18 mph.
      In 1928...snowfall of 0.6 inch was the only measurable snow
        of the month in the city.
      In 1947...post-frontal heavy snow totaled 6.3 inches over
        downtown Denver.  Most of the snow fell on the 30th.
        North winds were sustained to 17 mph on the 30th.
      In 1995...the foothills west of Denver received 5 to 9 inches
        of new snow...except for Bailey where 11 inches of snow were
        measured.  No snow fell at the site of the former Stapleton
        International Airport.
31    In 1890...northeast winds were sustained to 46 mph with gusts
        as high as 60 mph behind an apparent cold front.  A trace
        of sleet fell.
      In 1899...northwest winds were sustained to 44 mph with gusts
        as high as 48 mph.  The chinook winds warmed the temperature
        to a high of 49 degrees.
      In 1927...the temperature was below zero all day.  The high
        temperature of 3 degrees below zero was a record low
        maximum for the date.  The low temperature was 11 degrees
        below zero.
      In 1970...warm chinook winds whistled through Boulder.  A wind
        gust to 92 mph was recorded at the National Center for
        Atmospheric Research...while at the National Bureau of
        Standards...winds peaked to 70 mph.  Northwest winds gusting
        to 30 mph warmed the temperature to a high of 60 degrees at
        Stapleton International Airport.
      In 1993...occasional high winds occurred northwest of Denver
        and in the foothills.  A wind gust to 85 mph was recorded
        at Jefferson County Airport in Broomfield.  Wind gusts to
        86 mph occurred on Squaw Mountain with 75 mph recorded at
        Rollinsville.  West winds gusted to 46 mph at Stapleton
        International Airport.
      In 2011...an intense and fast moving storm system...produced a
        powerful windstorm across the Front Range. In the
        mountains and foothills...several locations recorded wind
        gusts in excess of 100 mph. Numerous trees were knocked
        down throughout Arapahoe National Forest. One man was
        killed when he was impaled by a falling tree limb while
        driving along U.S. Highway 36...north of Boulder. The
        strong winds produced extensive damage to fences and roofs...
        and also knocked down trees which resulted in power
        outages that affected 19 thousand residents along the
        Front Range.  In the mountains and foothills...peak wind
        gusts included: 111 mph...3 miles south-southeast of
        Pinecliffe; 101 mph...1 mile west of Lyons; 94 mph atop
        Berthoud Pass; 86 mph...3 miles south of Golden; 84 mph...
        4 miles northwest of Boulder; 81 mph in Boulder; 79 mph
        at Kenosha Pass...NCAR Mesa Lab and the junction of U.S.
        Highways 72 and 93; 77 mph at the National Wind Technology
        Center; and 76 mph...3 miles north-northwest of Morrison.
        Peak wind gusts for the Urban Corridor included: 80 mph...3
        mile east of Cedar Point; 77 mph in north Longmont; 67

        Watkins; 59 mph at Denver International Airport and Deer
        Trail; 58 mph at Rocky Mountain Regional Airport in
        Broomfield and 2 miles north-northwest of Louisville.
31-1  In 1900...low temperatures dipped to 19 degrees below zero on
        both days to establish daily record minimum temperatures.
      In 1975...only 4.2 inches of snow fell at Stapleton
        International Airport...while north of Denver a major
        blizzard raged.  All roads north of Denver into Wyoming
        were closed when strong winds whipped snow into 5 to 6
        foot drifts.  North winds gusted to 43 mph at Stapleton
        International Airport on the 31st...causing some blowing
        snow.  Freezing drizzle also fell on the 31st.
      In 1984...heavy snow fell in the foothills with 8 inches at
        Boulder and 6 inches in southern and western metro Denver.
        Only 1.5 inches of snow fell overnight at Stapleton
        International Airport.
      In 1991...a New Year`s Eve snow storm dumped 2 to 8 inches of
        snow across northeastern Colorado.  Snowfall totaled 3.4
        inches at Stapleton International Airport.  The 1.9 inches
        of snow that fell on the 31st was the only measurable
        snowfall of the month.
      In 2008...another brief period of high winds occurred in and
        near the foothills of Boulder and Jefferson Counties.  In
        Nederland...the strong wind snapped a blue spruce which
        landed on a nearby propane tank.  Some roofs in the
        immediate area were damaged and power lines were downed;
        which left 126 residences without electricity for six
        hours.  Peak wind gusts included 90 mph at the National
        Wind Technology Center...and 89 mph; 6 miles northwest of
        Boulder.  At Denver International Airport...a peak wind gust
        of 23 mph was measured from the southwest.
31-6  In 1973...the 31st marked the start of a protracted cold spell
        that extended into January of 1974 when temperatures
        dipped below zero on 7 consecutive days.  Record daily
        minimum readings occurred on the 3rd and 5th when the
        temperature plunged to 17 degrees below zero on both days.
        A record low daily maximum temperature of only 4 degrees
        occurred on the 5th.
31-7  In 1941...a protracted cold spell through January 7...1942...
        produced below zero low temperatures on 7 of the 8 days.
        A low temperature of 2 degrees on the 3rd prevented a
        string of 8 days below zero.  The coldest days during the
        period were the 1st with a high of 2 degrees and
        a low of 9 degrees below zero...the 4th with a high of 2
        degrees and a low of 11 degrees below zero...and the 5th
        with a high of 26 degrees and a low of 12 degrees below
        zero.
1     In 1875...the temperature fell 27 degrees between 3:00 PM and
        5:00 PM.  The high for the day was 43 degrees...and the low
        was 8 degrees.  Occasional snow flurries fell during the
        day...but not enough to cover the ground.
      In 1885...dense smoke choked the skies over downtown Denver
        until midday.
      In 1910...a rare trace of light rain fell during the morning.
      In 1911...post-frontal northeast winds were sustained to 40 mph.
        Only a trace of snow fell in downtown Denver.
      In 1952...snowfall of 0.03 inch was the only measurable snowfall
        of the month and resulted in 0.01 inch of melted snow...the
        only precipitation of the month.
      In 1956...west-northwest winds gusted to 52 mph at Stapleton
        Airport.
      In 1996...the first snow storm of the New Year dumped more
        than a foot of snow in the Front Range foothills with 4 to
        9 inches across the western and southern sections of metro
        Denver.  Snow totals included: 14 inches at Conifer; 11
        inches at Evergreen; and 10 inches at Eldora Ski Resort...
        west of Boulder.  Snowfall totaled only 1.2 inches at the
        site of the former Stapleton International Airport.  North-
        northeast winds gusted to 30 mph at Denver International
        Airport.
      In 2003...only a trace of snow fell at the site of the former
        Stapleton International Airport.  This...along with a trace
        of snow on the 22nd...was the only snow of the month...which
        equaled the 1934 record for the least snowiest January.
1-2   In 1896...warm chinook winds on the 1st became cold bora winds
        on the 2nd.  Southwest winds sustained to 60 mph with gusts
        as high as 66 mph warmed the temperature to a high of 55
        degrees on the 1st.  Northwest winds sustained to 54 mph
        with gusts to 60 mph resulted in snowfall of 0.3 inch and
        a high temperature of only 31 degrees on the 2nd.
1-5   In 1940...the first days of the month were characterized by a
        mixture of drizzle...light snow...and fog.  Fog occurred on
        each day.  On the 4th and 5th considerable glazing resulted
        from freezing drizzle.  All objects were coated with a
        glaze on the windward side.  This resulted in very slippery
        streets...which caused several minor traffic accidents.  The
        glaze was not heavy enough to damage wires and cables.
2     In 1972...strong northwest chinook winds in advance of a cold
        front gusted to 51 mph at Stapleton International Airport and
        caused temperatures to warm to a high of 55 degrees.
      In 1986...high winds occurred along the Front Range foothills.
        The strongest recorded gust was 82 mph in the Table Mesa
        area of Boulder.  Other places in Boulder reported gusts
        from 68 to 80 mph.  West winds gusted to 43 mph at
        Stapleton International Airport.
      In 1989...high winds between 60 and 70 mph were recorded in
        Boulder and along the eastern foothills.  No damage was
        reported.  West winds gusted to 49 mph at Stapleton
        International Airport.
2-3   In 1971...a major storm dumped a total of 8.4 inches of snow
        at Stapleton International Airport where north winds gusted
        to 23 mph.
      In 1972...a strong cold front late on the 2nd produced north
        wind gusts to 35 mph at Stapleton International Airport.
        Snow...heavy at times on the 3rd...totaled 6.4 inches as
        temperatures hovered only in the single digits.
      In 2000...heavy snow fell over the higher terrain of the Palmer
        Divide to the south of metro Denver.  Snowfall totaled 7
        inches 5 miles southwest of Sedalia.  Only 1.5 inches of
        snowfall were measured at the site of the former Stapleton
        International Airport.
2-4   In 1949...the worst blizzard in many years struck metro
        Denver and all of northern Colorado.  The storm produced
        blizzard conditions with wind gusts of 40 to 50 mph all
        day on the 3rd when temperatures were only in the single
        digits.  This resulted in extremely cold wind chill
        temperatures of 40 to 55 degrees below zero.  Stapleton
        Airport received 13.3 inches of snow from the storm...
        while downtown Denver received 11.8 inches.  The snow
        fell for 51 consecutive hours downtown.  Numerous lives
        were lost...and livestock losses were high across the
        northeastern plains of Colorado where extensive airlift
        operations were needed to bring supplies and food to
        isolated communities.
2-5   In 1959...very cold temperatures...to near zero and
        below...caused power and gas lines...water pipes...and
        automatic sprinkler systems to break.  In Boulder...
        merchandise and furnishings were water damaged when pipes
        burst in a department store...flooding three floors.  The
        temperature was below zero for 38 consecutive hours at
        Stapleton Airport on the 2nd...3rd...and 4th and plunged to
        a low of 13 degrees below zero on the 4th.
3     In 1874...heavy snowfall totaled 6 inches with 5 inches
        falling in 3 hours.  Melted snow totaled 0.40 inches
        of precipitation.  Northeast winds were sustained to 24
        mph.

        Center for Atmospheric Research in Boulder.  In downtown
        Boulder winds only gusted to 35 mph.  Northwest winds
        gusting to 49 mph produced some blowing dust at Stapleton
        International Airport.

        near Broomfield and reached 73 mph at Echo Lake in the
        foothills west of Denver.  West winds gusted to 46 mph at
        Stapleton International Airport.
      In 1994...high winds raked the eastern foothills.  Wind gusts

        Springs...and gusts to 85 mph occurred at the Rocky Flats
        Facility in northwest Jefferson County.  Northwest winds
        gusted to 41 mph at Stapleton International Airport.  No
        significant damage was reported.
      In 1996...very strong chinook winds gusting to 104 mph blasted
        the Front Range foothills and portions of metro Denver.

        was injured when strong crosswinds toppled his moving van
        into oncoming traffic along Colorado 93 south of Boulder.
        Two other people received minor injuries from flying debris.
        At the Rocky Flats Environmental Test Facility...eleven
        hazardous waste storage facilities received at least 100
        thousand dollars in damage.  In addition...several power
        lines were downed leaving 3 thousand homes and stores
        without power.  Hundreds of car windows were shattered...and

        County Airport...94 mph at the National Center for
        Atmospheric Research southwest of Boulder...91 mph at
        the Rocky Flats Environmental Test Facility...and 90 mph
        at Wondervu southwest of Boulder.  West-northwest winds
        gusted to only 39 mph at Denver International Airport
        where the chinook winds warmed the temperature to a high
        of 52 degrees.
      In 2004...bands of heavy snow fell across metro Denver.
        Snowfall totals included 6.5 inches in Broomfield and
        6 inches in Westminster...Arvada...and near Hudson.  Only
        0.5 inch of snow fell at the site of the former Stapleton

        with 9 inches recorded near Jamestown.  Southeast winds
        gusted to 25 mph at Denver International Airport.
      In 2006...locally high winds developed in northern
        Jefferson County over and near Rocky Flats.  Peak wind
        gusts from 75 to 91 mph were recorded during the
        afternoon.  A semi-trailer truck was blown onto its side
        on State Highway 93 atop Rocky Flats.  Strong winds also
        spread across metro Denver.  West winds gusted to 44 mph
        at Denver International Airport.
3-4   In 1982...wind gusting to 85 mph in the Table Mesa area of

        highest minimum temperature ever recorded in January.   The
        high temperature was 64 degrees.  The spring-like weather
        was the result of northwest chinook winds sustained to
        20 mph with gusts as high as 38 mph.
4-5   In 1996...snow began falling across the Front Range foothills
        and portions of metro Denver on the 4th.  Most snowfall
        amounts ranged from 4 to 6 inches.  Icy roads and blowing
        snow caused a 22 car accident on I-25 north of Denver...
        resulting in an 8-mile traffic back-up for several hours.
        Snowfall totaled 3.2 inches at the site of the former
        Stapleton International Airport.  North-northeast winds

        Boulder at the National Bureau of Standards and to 60 mph
        at Jefferson County Airport near Broomfield.  The high
        winds caused severe blowing snow in and near the foothills...
        completely blocking traffic in some areas...closing schools
        and industrial plants.  Houses under construction were
        damaged...and falling trees damaged cars in Boulder.  An

        Stapleton International Airport.
      In 1980 high winds in and near the foothills shattered
        windows...tore roofs from buildings...and caused many power
        outages.  Much of the damage was in Boulder...where winds
        gusted to at least 82 mph.  Wind gusts of 80 to 100 mph
        were common in the foothills.  West winds gusted to only

        the site of the former Stapleton International Airport.
6     In 1903...northwest winds were sustained to 45 mph with an
        extreme velocity of 48 mph.  The chinook winds warmed
        the temperature to a high of 66 degrees...which was a
        record maximum for the date.  The low temperature dipped
        to only 35 degrees.
      In 1962...strong winds caused nearly 14 hundred dollars in
        damage 2 miles north of Boulder.  West-northwest chinook
        winds gusted to 33 mph at Stapleton Airport in advance of
        a cold front that produced northeast wind gusts to 43 mph
        along with some blowing dust and 0.1 inch of snow.
      In 1972...a wind gust to 69 mph was recorded at the National
        Bureau of Standards in Boulder.  Only minor damage
        occurred.  Northwest winds gusted to 33 mph at Stapleton
        International Airport.
      In 2007...a large avalanche swept two vehicles off U.S.
        Highway 40...near Berthoud Pass...and partially buried them.
        The slide covered all three lanes of the highway.  Eight
        people were in the vehicles...but only one person was
        seriously injured.  He suffered several broken ribs.  The
        slide was approximately 200 feet wide and 15 feet deep.
6-7   In 1908...furious high winds were noted in Boulder but
        caused only minor damage and injury.
      In 1913...a very cold Arctic air mass caused temperatures to
        plunge to record levels.  The low temperature fell to 21
        degrees below zero on the 6th and to 18 degrees below
        zero on the 7th...both records.  The high temperature of
        only 8 degrees below zero on the 6th was a record low
        maximum for the date.
      In 1920...post-frontal heavy snowfall totaled 7.0 inches in
        downtown Denver.  North winds were sustained at 24 mph
        with gusts to 30 mph on the 6th.
      In 1923...warm chinook winds resulted in two temperature
        records.  Low temperatures of 37 degrees on the 6th
        and 42 degrees on the 7th equaled the record high
        minimums for the dates.  West winds were sustained to
        30 mph with gusts to 33 mph on the 6th.  Southwest
        winds were sustained to 47 mph with gusts to 52 mph
        on the 7th.  High temperatures were 53 degrees on the
        6th and 56 degrees on the 7th.
      In 1986...2 to 4 inches of snow fell over metro Denver...
        with 5 to 8 inches in the foothills west of the city.
        The 2.4 inches of snowfall recorded at Stapleton
        International Airport was the only snowfall of the
        month.  Northwest winds gusted to 24 mph at the
        airport.
      In 2006...a brief warm spell resulted in two temperature
        records.  High temperatures of 66 degrees on the 6th
        and 69 degrees on the 7th equaled the record daily
        maximum temperatures for each of those days.  Low
        temperatures remained above freezing and were within
        1 or 2 degrees of the record daily high minimums.
