...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.
5-7   In 1978...a major storm dumped heavy snow across metro Denver.
        At Stapleton International Airport...snowfall totaled 8.5
        inches...northeast winds gusted to 46 mph...and temperatures
        plunged from a high of 49 degrees on the 5th to a low of
        only 6 degrees on the 6th.  Maximum temperature of 6 degrees
        on the 7th was a new daily record low maximum reading.  Most
        of the snow...6.7 inches...fell on the 5th.
5-8   In 1983...high winds occurred in and near the foothills each
        day.  Wind gusts to 63 mph were registered in Golden Gate

        gusts to 80 mph occurred on Lookout Mountain.  In Denver
        winds gusted to 65 mph.  Damage in Boulder totaled 15
        hundred dollars.
7     In 1897...west winds were sustained to 53 mph with gusts to
        66 mph.  The chinook winds warmed the temperature to a
        high of 62 degrees...the warmest day of the month.
      In 1957...a vigorous cold front produced a dust storm as it
        moved south across metro Denver.  West-northwest wind gusts
        to 59 mph were recorded at Stapleton Airport where the
        surface visibility was briefly reduced to 1/2 mile in
        blowing dust.  Light snowfall of only 0.8 inch followed
        the passage of a secondary Canadian cold front.
      In 1958...the worst wind storm in several years caused 10
        thousand dollars damage in Boulder where wind gusts were

        two-hour flight delays.  Northeast winds gusted to 25 mph.
      In 2005...a brief cold snap resulted in record breaking
        temperatures.  The low temperature of 13 degrees below zero
        was a record minimum for the date.  The high temperature of
        only 3 degrees was a record low maximum for the date.  The
        cold temperatures were accompanied by 1.4 inches of light
        snow that was measured at Denver Stapleton overnight on the
        6th and 7th.
7-9   In 1919...an apparent Arctic cold front brought extreme cold
        and light snow to the city.  Snowfall totaled only 2.5
        inches on the 7th and 8th.  Temperatures dipped to lows
        of 14 degrees below zero on the 8th and to 20 degrees below

        near Bergen Park in the foothills west of Denver.  Gusts
        were estimated to 70 mph.  Northwest winds gusted to
        33 mph at Stapleton International Airport.
8-9   In 1943...4.5 inches of snow fell in downtown Denver.  This
        was the only measurable snow of the month.  North winds
        were sustained to 26 mph on the 8th.
      In 2003...snowfall totaled 3 to 6 inches across metro Denver.
        Snowfall was heavier in and near the foothills with
        8.0 inches measured in Boulder and 10 miles southwest of
        Sedalia.  Snowfall was 3.9 inches at the site of the
        former Stapleton International Airport.  Most of the snow
        fell on the 8th...as the snow ended shortly after midnight.
        North winds gusted to 29 mph at Denver International
        Airport.
      In 2008...an upslope snowstorm produced heavy snow in and near
        the foothills of Boulder...Jefferson and Douglas Counties...
        and along the Palmer Divide south of Denver.  Storm totals
        in the foothills ranged from 8 to 15 inches.  In Boulder
        and in areas west and south of Denver...storm totals ranged
        from 6 to 13 inches.  The snowfall measurement at Denver
        International Airport was 3.9 inches.
     In 2023...a storm system produce a period of moderate to heavy

        foothills and Palmer Divide. Storm totals ranged from 6 to
        14 inches in the mountains and foothills...with 4 to 7 inches
        over Boulder as well as western and southern portions of
        metro Denver. Interstate 70 closed was closed for a few
        hours west of Denver due to heavy snow as well as vehicle
        spinouts. Several accidents were also reported around the
        Denver metro area...with highest impacts on the west side of
        the city and in Boulder. Officially...just 0.4 inch of
        snowfall occurred at Denver International Airport while
        6.5 inches of snowfall was measured at the National Weather
        Service in Boulder.
8-10 In 1985 a slow moving storm dumped 10 to 20 inches of snow
        over the northeast plains...closing schools and businesses
        in many areas along the Front Range north of Denver.  At
        Stapleton International Airport...snowfall totaled 9.9 inches
        with a maximum snow depth of 7 inches on the ground.  North
        winds gusted to 24 mph.  The snow caused long air traffic
        delays at Stapleton International Airport on the 9th.
      In 1997...persistent light to moderate snowfall combined
        with strong and gusty northerly winds to produce much
        blowing and drifting snow across metro Denver.  The
        hardest hit areas were south of Denver where north winds
        at speeds of 20 to 35 mph with gusts to 45 mph caused near
        whiteout conditions.  The strong winds produced drifts
        2 to 4 feet deep and dropped wind chill temperatures
        well below zero.  Sections of both I-25 and I-70 and other
        roads were closed as travel became impossible due to
        blowing snow.  Numerous traffic accidents were reported and
        a handful of people were stranded during the snowstorm.

        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     In 1898...the very cold air mass that settled over the
        city behind an apparent cold front on the 7th plunged
        temperatures to a low of 20 degrees below zero.  The
        high temperature climbed to only 5 degrees.
      In 1910...chinook west winds sustained to 46 mph warmed
        the temperature to 60 degrees...the warmest reading
        of the month that year.

         east of Denver with gusts to 50 mph.
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
        record high minimums for the dates.  West winds were
        sustained to 38 mph on the 12th and to 25 mph on the
        13th.
13    In 1955...strong winds raked the foothills.  A wind gust to 72

        to speeds of 23 mph at Stapleton Airport.
      In 1988...high winds again occurred in Boulder where winds
        were clocked to 66 mph.  West winds gusted to 43 mph at
        Stapleton International Airport.
13-14 In 1902...heavy snowfall totaled 6.4 inches in the city
        overnight.  North winds were sustained to 18 mph with

      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
        Denver were generally 35 to 50 mph.  Northwest winds gusted
        to 48 mph at Stapleton International Airport on the 13th.
