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

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
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.
2-3   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 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
      In 1887...west winds were sustained to 44 mph in the city.
      In 1913...northwest chinook winds sustained to 42 mph with
        gusts to 52 mph warmed the temperature to a high of 58
        degrees.  The low temperature was only 40 degrees.
      In 1951...northwest winds gusted to 56 mph at Stapleton
      In 1967...a strong chinook wind reached 90 mph at the National
        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.
      In 1986...winds gusted to 63 mph at Jefferson County 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
        to 99 mph were recorded on Squaw Mountain...south of Idaho
        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.
        Three people were injured in separate incidents.  One man
        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
        several signs were toppled from buildings.  Some of the
        strongest wind gusts included:  104 mph at Boulder Municipal
        Airport...98 mph in south Boulder...96 mph at Jefferson
        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
        International Airport.  More snow fell in the foothills
        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
        Boulder caused a few power failures.  West winds gusted
        to only 32 mph at Stapleton International Airport.
      In 2000...high winds buffeted the foothills of Boulder County.
        Wind gusts were reported to 91 mph at Nederland and 81 mph
        at the National Center for Atmospheric Research on the mesa
        southwest of Boulder.  Southwest winds gusted to only 31 mph
