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

15-23 In 1962...a protracted cold spell kept metro Denver in the
        deep freeze for more than a week.  From the 15th thru the
        23rd...low temperatures were zero or below for 9 consecutive
        days...but a daily record low was set only on the 22nd when
        the temperature dipped to 14 degrees below zero.  A record
        low maximum for the date was also set on the 22nd when the
        temperature climbed to only 11 degrees.  The coldest high
        temperature was 3 degrees above zero on the 21st...which did
        not break the record.  The protracted cold was broken for
        only a few hours on the afternoon of the 20th when chinook
        winds warmed the temperature to a high of 38 degrees before
        another surge of cold Arctic air plunged temperatures
        back into the deep freeze that evening.  The severe cold
        caused much damage to water systems.  A woman was frozen to
        death at Morrison.  There were other deaths attributable to
        the weather...including traffic deaths and heart attacks
        from overexertion.
18-24 In 2005...a week of mid-winter unseasonably warm weather
        pushed high temperatures into the 60`s or more on all
        but one day.  During the period...the highest temperature
        of 70 degrees on the 20th was a new record maximum for
        the date.  Low temperatures remained above freezing on
        4 of the days.
22-23 In 1982...wind gusts up to 101 mph were clocked at Wondervu.
        Wind gusts of 60 to 80 mph were common along the Front
        Range foothills from Boulder north.
22-26 In 1948...the longest period of snowfall on record (92 hours
        and 3 minutes) occurred in downtown Denver where a total of
        13.6 inches of snow fell.  At Stapleton Airport...19.0 inches
        of snow fell...making it the heaviest snow in January and the
        5th heaviest snow of record at that time.  North winds were
        sustained to a velocity of 23 mph on the 25th...but generally
        the winds were light throughout the storm.  The snow
        disrupted traffic...but street clearing was begun soon after
        it became apparent that the snow would be heavy.  Over the
        5 days...temperatures ranged from a high of 48 degrees on
        the 22nd to a low of 1 degree on the 26th.  Most readings
        were in the teens and 20`s during the storm.
23    In 1872...a brisk northerly wind set in about noon...blew
        almost a gale about 6:00 PM...and continued brisk until
        night.  A light snow commenced during the late afternoon
        and continued all night.
      In 1886...northwest winds were sustained to 40 mph in the city
        around sunrise.  A cold wave accompanied the strong winds.
      In 1897...a vigorous cold front produced northeast winds
        sustained to 45 mph with gusts to 50 mph.  Temperatures
        plunged from a high of 59 degrees to a low of 11 degrees
        in the evening.  The very cold temperatures persisted
        through the 28th.
      In 1934...the date marked the last day of the longest period
        of consecutive days without measurable precipitation in the
        city.  The 52 day period began on December 3...1933.
      In of the strongest windstorms in several years
        pounded the Front Range foothills from Colorado Springs
        north to the Wyoming border.  The highest wind gust at
        lower elevations was 105 mph recorded at Table Mesa in
        Boulder.  Other sections of Boulder recorded wind gusts of
        80 to 90 mph.  In Boulder...the high winds broke windows and
        damaged power lines and transformers.  Power outages were
        widespread and traffic lights were downed.  The winds blew
        down a partially constructed viaduct in east Boulder.  Nine
        unanchored concrete girders...each weighing 45 tons...were
        blown off their supports.  Cars were blown off I-70 near
        Morrison...and a tractor trailer and a mobile home were
        knocked over.  In electric company crewman was
        burned while replacing a power line.  Wind gusts to 92 mph
        were clocked at Jefferson County Airport in Broomfield
        before the site anemometer was blown down by the wind.
        The strong winds spread over all the metro area with a
        northwest wind gust to 52 mph recorded at Stapleton
        International Airport.
      In 1992...high winds buffeted the eastern foothills.  A wind
        gust to 63 mph was recorded at Rocky Flats northwest of
        Denver.  West winds gusted to 40 mph at Stapleton
        International Airport.
      In 2002...low level upslope flow combined with an upper level
        jet stream created bands of heavy snow over portions of
        the Front Range foothills and metro Denver.  The areas
        hardest hit were the foothills of Jefferson and Douglas
        counties and the I-25 corridor from the southern suburbs
        of Denver to around Castle Rock.  Snow totals included:
        9 inches at Intercanyon...Roxborough State Park...and near
        Sedalia; 8.5 inches atop Crow Hill and near Tiny Town;
        8 inches at Ken Caryl and near Castle Rock; 7 inches in
        Lakewood; 6.5 inches at Littleton; and 6 inches in Castle
        Rock.  Only 3.6 inches of snow were measured at the site
        of the former Stapleton International Airport.
23-24 In 1921...heavy snowfall in downtown Denver totaled 8.0
        inches overnight.  Northwest winds were sustained to
        22 mph with gusts to 25 mph on the 24th.
