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

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.
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.
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.
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.
1     In 1904...northwest winds were sustained to 51 mph with
        gusts to 60 mph.  The chinook winds warmed the
        temperature to a high of 55 degrees.
      In 1907...west winds sustained to 42 mph warmed the
        temperature to a high of 59 degrees.
      In 1932...the temperature rose from a low of 8 degrees
        at 7:00 AM to the high of 58 degrees at 2:30 PM.  The
        biggest jump occurred from 16 degrees at 8:00 AM to
        42 degrees at 9:10 AM.
      In 1951...the lowest recorded temperature in February...25
        degrees below zero...occurred.  The same temperature was
        also reached on February 8...1936.
      In 1963...west-southwest winds gusted to 66 mph at Stapleton
        Airport where the strong chinook winds warmed the
        temperature to a maximum of 70 degrees.
      In 1970...snowfall of 0.3 inch contained only 0.01 inch of
        melted snow.  This was the only measurable snow and
        precipitation for the month...making it the driest and
        least snowiest February on record.  Snowfall also was
        only 0.3 inch on February 22-23...1992...equaling the
        least snowiest February.
      In 1980...high winds occurred in the foothills.  Wind gusts
        to 75 mph were reported at Wondervu.  Northwest winds
        gusted to 32 mph at Stapleton International Airport.
      In 1995...a short blast of early morning winds near the
        foothills produced a gust to 64 mph at Rocky Flats in
        northern Jefferson County.  Winds gusting to 59 mph in
        Lakewood downed a few tree branches in residential areas.
        West winds gusted to 37 mph at Stapleton International
        Airport where the warm winds kept the temperature from
        falling below 43 degrees...setting a new record high
        minimum for the date.  The temperature climbed to a
        non-record high of 63 degrees.
1-2   In 1934...light chinook winds warmed temperatures to record
        levels on both days.  Record maximum temperatures
        reached 73 degrees on the 1st and 74 degrees on the 2nd.
        West winds were sustained to 18 mph on the 1st.
1-3   In 1996...cold Arctic air plunged temperatures below zero
        for more than 35 consecutive hours from late on the 1st
        until sunrise on the 3rd.  The temperature warmed to only
        1 degree below zero on the 2nd after a record low of
        16 degrees below zero.
1-4   In 2011...a frigid arctic airmass settled into Front Range
        Urban Corridor.  At Denver International Airport...
        overnight low temperatures...from the 1st to the 3rd...
        were 13 below zero...17 below zero and zero respectively.
        The icy temperatures caused pipes to crack and burst
        following the freeze.  In Loveland...firefighters
        responded to more than a dozen water pipe breaks...most
        in fire sprinkler systems at and
        assisted care facilities.  At CU Earth Science Library
        in Boulder...more than 1000 books and several costumes
        for an upcoming production were damaged.  At the county
        courts administration building in Jefferson County...a
        steady stream of water from a crack on the 5th floor...
        went unnoticed on the 3rd and flooded all the floors of
        the administration wing overnight.  As a result...much of
        the office and carpet sustained
        water damage.  A burst sprinkler line caused minor
        damage at the Platte Valley Medical Center in Brighton.
        The icy temperatures forced to closure of several school
        districts as well.
1-5   In 1985...the most bitter cold spell of the winter season
        brought sub-zero temperatures to metro Denver.  Daily low
        temperature records were broken at Denver.  The usual cold
        weather problems struck including stalled vehicles...jammed
        traffic lights...and frozen water and sewer lines.  At
        Stapleton International Airport...the high temperature
        was only 2 degrees above zero on the 1st...setting a record
        low maximum for the date.  Low temperatures reached 13 below
        zero on the 1st...12 below on the third...and 14 below on the
1-6   In of the century`s worst doses of winter weather
        ravaged the entire state.  Bitterly frigid weather moved
        into metro Denver on the 1st as snow buried many sections
        of the state.  In metro Denver where 3 to 6 inches of snow
        fell...blowing snow and resultant poor visibilities caused
        a 46-car pile-up on I-25 in the middle of the city on the
        4th.  During the period...2 to 3 hour delays were common at
        Stapleton International Airport where snowfall from the
        storm totaled 4.3 inches and northeast winds gusted to 30
        mph on the 1st.  Intense cold accompanied the storm.
        Temperatures in Denver stayed below zero continuously for
        the best part of 3 days (3rd...4th...5th)...for a total of 69
        hours.  This is the fourth longest sub-zero period on
        record.  Wind chill temperatures reached 50 degrees below
        zero.  The mercury dipped to 24 degrees below zero on the
        5th...setting a record for the date.  This was the city`s
        coldest temperature in over 26 years.  Low temperatures
        dipped below zero on 8 consecutive days (2nd-9th).  High
        temperature of 9 degrees below zero on the 4th was a record
        low maximum for the was the high of 5 degrees on
        the 5th.  Extensive damage occurred when pipes and water
        lines froze and broke.  Thousands of cars failed to start.
        On the 3rd...a 57-year-old woman died of hypothermia in an
        Arvada park.  Eighteen high school students were treated
        for hypothermia after a 2-hour ride through Jefferson
        County in an unheated bus.  At least 2 cases of frostbite
        were reported; there were undoubtedly many more.
1-9   In 1883...a protracted cold period occurred when low
        temperatures dipped below zero for 9 consecutive days.
        Low temperatures ranged from 22 degrees below zero on
        the 4th to 2 degrees below zero on the 1st and 6th.  High
        temperatures ranged from 10 below zero on the 3rd to
        23 on the 9th.  Several temperature records were set
        that still stand today.  Record lows of 18 below and
        22 below zero occurred on the 3rd and 4th.  Record low
        maximum readings of 2 below and 10 below zero occurred on
        the 2nd and 3rd.  The high of only 10 below zero on the
        3rd is the coldest maximum temperature ever recorded in
