...This week 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
        mass.
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.
10-11 In 1933...downslope winds produced warm temperatures...resulting
        in record high minimums of 46 degrees on the 10th and 44
        degrees on the 11th.  High temperatures of 66 degrees on the
        10th and 62 degrees on the 11th were not records.  Southwest
        winds were sustained to 16 mph on the 10th.
      In 1939...high temperatures of 70 degrees on the 10th and 74
        degrees on the 11th were record maximums for the dates.
        The low temperatures of 39 degrees on the 10th and 41
        degrees on the 11th were not records.
      In 1948...high winds in Boulder and Louisville caused 1750
        dollars in damage.  Wind gusts in excess of 70 mph were
        reported at Valmont and Boulder Airport.  Chinook wind
        gusts to 60 mph briefly reduced the visibility to 1/4 mile
        in blowing dust at Stapleton Airport.
      In 1989...the season`s greatest snowfall to date hit metro
        Denver with 6 to 12 inches of snow.  Flight delays at
        Stapleton International Airport reached 2 hours.  Multiple
        wrecks snarled traffic on I-25 both north and south of the
        city.  Snowfall totaled 7.0 inches at Stapleton
        International Airport where north winds gusted to 25 mph
        on the 10th.

        Northwest winds gusted to 31 mph at Stapleton International
        Airport.
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.

      In 1992...an 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

      In 1951...heavy snowfall totaled 5.9 inches at Stapleton
        Airport.
      In 1987...a snowstorm dropped 2 to 8 inches of snow along the
        Front Range foothills.  Eight to 12 inches fell just south
        of Denver.  Icy streets and highways contributed to many
        traffic accidents across metro Denver and flights were
        delayed at Stapleton International Airport where 2.7
        inches of snow fell and northeast winds gusted to 17 mph.
      In 1991...high winds pummeled metro Denver.  Wind gusts to 93
        mph were recorded at Rollinsville.  Wind speeds across metro

        to 48 mph at Stapleton International Airport on the 13th.
14    In 1926...an intrusion of cold air resulted in temperatures
        remaining below zero.  The high temperature of one degree
        below zero was a record low maximum for the date.  The low

      In 1985...a wind gust to 61 mph was recorded at Table Mesa in
        Boulder.
      In 1996...high winds gusting from 60 to nearly 80 mph moved
        off the Front Range foothills and over the northeast
        Colorado plains in the wake of a fast moving cold front.
        The strongest wind gusts included 79 mph at Golden Gate
        Canyon and 70 mph near Table Mesa in southwest Boulder.
        At Denver International Airport...west-northwest winds

        Snowfall along the Front Range was in the 6 to 12 inch
        range.  Snowfall totaled 5.8 inches at Stapleton
        International Airport where north winds gusted to 38 mph.
      In 1990...high winds howled across metro Denver behind a
        strong Pacific cold front.  Boulder was hardest hit by the
        high winds.  A wind gust to 120 mph was recorded in south
        Boulder where winds stripped the roof off a garage...a
        vacant gas station...and a house under construction.
        Elsewhere in Boulder...several trees were blown down.  In
        Boulder Canyon...the winds toppled two cinder block walls on
        a house under construction.  Four Boulder County women were
        treated for injuries caused by the wind.  The injuries were
        confined to a broken wrist...a mild concussion...bruises...and
        facial cuts.  Two semi-tractor trailers were blown over by
        the fierce winds south of Boulder.  Another truck rollover
        occurred southeast of Golden.  Drivers of all three trucks
        suffered only cuts and bruises.  Several vehicles were
        trapped in a blinding dust storm on the Denver-Boulder
        Turnpike near Broomfield.  Drivers were forced to stop
        along the highway for several minutes during the storm and
        witness their vehicles being pelted with sand and gravel.
        A wind gust to 97 mph was recorded in Golden.  High winds
        were also reported in Arvada...Boulder...and Lakewood.  Winds
        toppled a number of utility poles and wooden fences...blew
        out windows...and caused structural damage to a large
        apartment complex on the west side of Golden.  Wind gusts
        of 70 to 100 mph caused considerable damage to several
        large billboards north of Golden...as well as damaging the
        paint...trim...and glass on numerous vehicles in the area.
        A west wind gust to 51 mph was recorded at Stapleton
        International Airport.
15    In 1999...high winds developed in and near the foothills as
        a strong upper level jet moved into the area.  Although
        most wind gusts were in the 70 to 80 mph range...a weather
        spotter located 1 mile south of Fritz Peak near
        Rollinsville measured a peak wind gust to 124 mph.  Other
        wind reports included wind gusts to 77 mph at the National
        Center for Atmospheric Research in Boulder and atop Blue
        Mountain and 70 mph at the National Wind Technology Center
        on Rocky Flats south of Boulder.  West winds gusted to only
        32 mph at Denver International Airport.
      In 2000...high winds developed in the foothills of Boulder
        County...but winds were strong across all of metro Denver.
        Winds gusted as high as 72 mph at the National Center for
        Atmospheric Research on the mesa just southwest of Boulder.
        West winds gusted to 44 mph at Denver International Airport.
15-16 In 1964...high winds raked metro Denver...causing considerable
        damage.  Wind gusts to 81 mph were recorded at Rocky Flats
        northwest of Denver...94 mph at Jefferson County Airport
        near Broomfield...48 mph in downtown Boulder...and 70 mph
        in Littleton.  West wind gusts to 67 mph were recorded
        at Stapleton International Airport.  A man working on
        construction in downtown Denver died from injuries after
        being struck by a 5-foot by 8-foot section of plank runway
        blown by the strong winds.  Several people were blown down
        by the strong winds or hit by flying objects.  Buildings...
        roads...trees...and power equipment were damaged.  Roads were
        closed east of Denver due to blowing dust.
      In 1981...wind gusts to 60 mph were common in the foothills
        northwest of Denver.  West wind gusts to 47 mph were
        recorded at Stapleton International Airport where the
        visibility was briefly reduced to 3 miles in blowing dust.
      In 1996...strong pre-frontal winds developed in the foothills
        of Boulder County ahead of an Arctic cold front that moved
        into northeastern Colorado late on the morning of the 16th.
        Wind gusts of 70 to 75 mph were clocked at Table Mesa in
        southwest Boulder.
16    In 1912...northwest winds were sustained to 44 mph with an
        extreme velocity of 45 mph.
      In 1921...north winds were sustained to 46 mph with gusts to
        50 mph behind a vigorous cold front.  Only a trace of snow
        fell.
      In 1954...a vigorous cold front produced sustained north winds
        to 45 mph with gusts as high 54 mph.  Visibility was
        reduced to 1 mile in blowing dust at Stapleton Airport.
      In 1955...sustained west winds to 44 mph with gusts as high as
        58 mph were recorded at Stapleton Airport.
      In 1994...a wind gust to 108 mph was recorded atop Squaw
        Mountain west of Denver with a gust to 92 mph in
        Rollinsville southwest of Boulder.  West winds gusted
        to 48 mph at Stapleton International Airport.
      In 1996...a vigorous Arctic cold front moved across metro
        Denver.  Heavy snow and strong winds accompanied the
        front as near whiteout conditions in snow and blowing
        snow developed suddenly.  Northerly winds gusted from
        40 to 60 mph behind the front.  Dozens of accidents
        occurred as roads and highways quickly turned to a glaze
        of ice.  Snowfall amounts ranged from 4 to 6 inches across
        metro Denver and in the foothills.  The exception was at
        Eldorado Springs south of Boulder where 8 inches of new
        snow were measured.  Snowfall totaled only 1.8 inches at
        the site of the former Stapleton International Airport.
        Officially...this was the only measurable snow of the month
        in Denver.  At Denver International Airport...north winds
        gusted to 34 mph.
      In 1999...another brief round of high winds developed in and
        near the foothills of Boulder County.  Peak wind gusts
        included 83 mph at the National Center for Atmospheric
        Research near Boulder and 74 mph atop Niwot Ridge and
        at the National Wind Technology Center on Rocky Flats
        south of Boulder.  West winds gusted to only 33 mph at
        Denver International Airport where the temperature warmed
        to a high of 54 degrees.
      In 2000...high winds in the mountains spread into the
        foothills west of Denver.  Winds gusted to 87 mph at
        Georgetown Lake and at the National Center for
        Atmospheric Research in Boulder.  Winds gusted to
        72 mph at the National Wind Technology Center south
        of Boulder.
16-17 In 1908...heavy snowfall totaled 7.9 inches in downtown
        Denver where north winds were sustained to 20 mph on
        the 17th.  Temperatures were in the teens and 20`s.
      In 1939...low temperatures of 49 degrees on the 16th and
        43 degrees on the 17th were record high minimums for
        the dates.  High temperatures of 65 on the 16th and 72
        on the 17th were not records.
      In 1980...chinook winds blew through the night in Boulder with
        a peak reported gust to 75 mph.  Northwest winds gusted to
        30 mph at Stapleton International Airport on the 17th.
        The strong chinook winds warmed temperatures to record
        daily highs of 70 degrees on the 16th and 73 degrees on
        the 17th.
17    In 2000...high winds gusting from 60 to 74 mph howled across
        the northeast plains of Colorado.  In Parker where winds
        gusted to 60 mph...a 20-foot by 40-foot piece of roof was
        ripped from a building.  West winds gusted to 53 mph at
        Denver International Airport.  This was the highest wind
        gust of the month at the airport.  An intense...but very
        localized wind gust to 112 mph was measured near
        Georgetown Lake in the foothills west of Denver.
17-24 In 1924...a prolonged cold spell occurred after mild
        temperatures during the first half of the month.  Most
        low temperatures dipped below zero with the coldest
        reading of 15 degrees below zero occurring on the 24th.
        The high temperature of only 5 degrees on the 18th was
        a record low maximum for the date.
