26-1  In 1888...a protracted warm spell lasted a week.  Maximum
        temperatures ranged from 62 degrees on the 29th to an
        all time record high for the month of 76 degrees on the
        27th.  Daily record high temperatures of 76...69...and 71
        occurred on the 27th...28th...and 30th respectively.
        Record high minimum temperatures of 47 and 34 occurred
        on the 26th and 27th.
27-31 In 1951...a major storm dumped 10.1 inches of snowfall at
        Stapleton Airport.  Most of the snow...8.3 inches...fell on
        the 29th.  Cold Arctic air accompanied the snow.  Several
        temperature records were set...including record low maximum
        temperatures of 4 on the 28th and 4 below zero on the 29th
        and record low temperatures of 12 below zero on the 29th
        and 24 below zero on the 31st.  Temperatures were below
        zero for 45 consecutive hours.
29-31 In 1883...a major winter storm dumped 19.3 inches of snow on
        downtown Denver.  Most of the snow...12.2 inches...fell
        on the 31st.  This was the heaviest snowfall to hit the
        city in years.  Temperatures plunged from a high of 52
        degrees on the 29th to a low of 13 degrees on the 31st.
        Precipitation from the storm totaled 2.23 inches.  The
        1.22 inches of precipitation on the 31st was the greatest
        calendar day and 24 hour precipitation ever recorded in
        the city during the month of January.
30-31 In 1908...an apparent strong cold front plunged temperatures
        45 degrees in 24 hours from 47 degrees at noon on the 30th
        to only 2 degrees at noon on the 31st.  North winds were
        sustained to 30 mph on the 30th.  Snowfall was only 0.8
        inch on the 31st.
      In 1965...a major storm dumped 10.4 inches of snow over
        metro Denver.  After 5 inches of snow fell in Boulder...
        strong chinook winds developed...warming the temperature
        25 degrees in 90 minutes.  Wind gusts to 97 mph were
        recorded on Table Mountain in Boulder.  Winds gusts to
        53 mph were measured in downtown Boulder where some
        damage occurred.  Minor wind damage also occurred in
        western suburbs of Denver.  West winds gusted to 51 mph
        at Stapleton International Airport on the 31st.
      In 2005...a winter storm brought heavy snow to the Front
        Range foothills.  Storm totals included:  17 inches at
        Aspen Springs...13 inches 7 miles southwest of Boulder
        and at Lake Eldora...12.5 inches near Blackhawk...11.5

        near Evergreen and Golden and at Gross Reservoir...and
        10 inches at Cabin Creek.  Lesser amounts of snow fell
        over the city.  Only 1.9 inches of snow were measured
        overnight at Denver Stapleton.  North winds gusted to
        30 mph at Denver International Airport...where freezing
        fog during the early morning of the 30th reduced the
        surface visibility to as low as 1/8 mile.  Light rainfall...
        rare in January...totaled 0.06 inch at Denver Stapleton on
        the early morning of the 30th.
30-7  In 1985...a cold front on the 29th produced a protracted cold
        spell as Arctic air remained entrenched across metro Denver.
        While the only daily temperature record set was a low
        maximum reading of 2 degrees on February 3rd...minimum
        temperatures plunged well below zero on 9 consecutive days.
        The coldest readings were 15 degrees below zero on January
        31st and 14 degrees below zero on February 5th.

        Boulder.
      In 1951...the low temperature plunged to 24 degrees below
        zero.
      In 1933...snowfall was 0.2 inch in downtown Denver.  This was
        the only measurable snowfall of the month and resulted in
        0.01 inch of melted snow...the only measurable precipitation
        of the month.
      In 1964...high winds blew down a sidewalk cover where a
        building was under construction...injuring a young woman.
        Three men were injured when a brick wall at a construction
        site toppled on them.  All were treated for face...leg and
        neck injuries.  A west-northwest wind gust to 47 mph was
        recorded at Stapleton International Airport.
      In 1969...high winds struck Boulder with gusts to 115 mph
        recorded at the National Center for Atmospheric Research
        and 83 mph in downtown Boulder.  Schools were closed
        because of danger from flying debris.  Some damage and
        minor injuries occurred.  Northwest winds gusted to 35 mph
        at Stapleton International Airport.
      In 1985...bitterly cold weather froze pipes and cars and
        forced some schools to close across metro Denver.  Minimum
        temperatures dipped to as low as 15 below to 20 below zero
        across metro Denver.  The low temperature was 15 below
        zero at Stapleton International Airport.
31-1  In 1963...high winds struck metro Denver.  The strong
        chinook winds reached 101 mph in Littleton...80 mph in
        Denver...and 90 mph at Rocky Flats.  Among the hardest hit
        areas were Boulder where buildings under construction were
        blown down...porches and roofs blown off buildings...and
        power lines damaged.  Damage totaled 100 thousand dollars
        in Boulder alone.  In other areas...utility lines were
        damaged and many signs...antennas...and road markers were
        blown down.  At Stapleton Airport...west winds gusted to
        44 mph on the 31st and 66 mph on the 1st.  The chinook
        winds warmed maximum temperatures to 65 degrees on the
        31st and to 70 degrees on the 1st.
      In 2015...a concentrated band of heavy snowfall developed
        over the Urban Corridor...during the late evening hours
        of the 31st...and carried over into the early morning hours
        of the 1st. The band extended from northwest of Lyons...
        through northwest Denver and into Aurora...Parker...and
        Elizabeth. Snowfall rates of 2 to 4 inches per hour were
        observed under the most intense part of the band. Storm
        totals included: 9.2 inches near Westminster; 9 inches...
        5 miles east of Boulder; 8 inches in Federal Heights and
        4 miles northwest of Parker; 7.5 inches near Aurora and

        snowfall was observed.
31-8  In 1963...warm weather that began with the strong chinook
        winds on the 31st and 1st continued through the 8th.
        Maximum temperatures through the period ranged from 52
        degrees on the 2nd to 76 degrees on the 5th...which was
        a new record high for that date.
31-12 In 1899...a protracted cold spell lasted almost two weeks.
        Low temperatures plunged below zero on all days but
        February 9th with a reading of 6 degrees.  The coldest
        low temperature of 22 degrees below zero on February 6th
        was a record low for the date.  Low temperatures of 20
        degrees below zero occurred on both February 11th and 12th...
        but only the 11th remains as the record minimum for the
        date.  High temperature of only 5 degrees below zero on
        February 11th was a record low maximum for the date.  High
        temperatures climbed to only zero degrees on both February
        2nd and 3rd...but were not records.  Intermittent light snow
        or flurries fell during the period.  The most snowfall...2.0
        inches...occurred on February 2nd.
