... Today 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.
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.
        Snowfall totals included: 22 inches at Conifer... 13 inches
        at Castle Rock... 12 inches at Parker... and 8 inches in
        southeast Aurora. Snowfall totaled 5.5 inches at the
        site of the former Stapleton International Airport.
        North winds gusted to 36 mph at Denver International
        Airport on the 10th.
8-12 in 1932... the second longest sub-zero period on record in
        Denver occurred. The temperature fell below zero shortly
        after 1:00 PM on the 8th and remained below zero for 92
        hours until 9:00 am on the 12th. The lowest temperature
        recorded during this period was 13 degrees below zero on
        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.
9-13 in 1961... cold Arctic air produced a protracted cold period.
        The temperature plunged to 16 degrees below zero on the
        10th... establishing a new record for the date and the
        coldest reading since 25 degrees below zero on February 1...
        1951. Low temperatures dipped below zero on 5 consecutive
        days with 9 degrees below zero on the 9th... 16 below on the
        10th... 10 below on the 11th... and 12 below on both the 12th
        and 13th. High temperatures reached only 3 degrees on the
        10th and 6 degrees on the 11th.
10 in 1953... snowfall totaled 3.8 inches at Stapleton Airport
        where northeast winds were sustained at speeds to 47 mph
        and gusted to 60 mph behind a cold front.
      In 1969... sustained winds of 30 mph with gusts to 55 mph in
        downtown Boulder caused minor damage. Northwest winds
        gusted to 39 mph at Stapleton International Airport.
      In 1980... winds to 60 mph whistled through Boulder.
      In 1987... strong winds in the foothills spread over northern
        portions of Metro Denver. Wind gusts of 60 to 75 mph were
        common in Boulder and southwestern Weld counties. However...
        the highest reported wind gust... 94 mph... occurred near
        Rollinsville. A northwest wind gust to 36 mph was recorded
        at Stapleton International Airport.
10-11 in 1933... downslope winds produced warm temperatures... resulting
        in record high minimums of 46 degrees on the 10th and 44
        degrees on the 11th. High temperatures of 66 degrees on the
        10th and 62 degrees on the 11th were not records. Southwest
        winds were sustained to 16 mph on the 10th.
      In 1939... high temperatures of 70 degrees on the 10th and 74
        degrees on the 11th were record maximums for the dates.
        The low temperatures of 39 degrees on the 10th and 41
        degrees on the 11th were not records.
      In 1948... high winds in Boulder and Louisville caused 1750
        dollars in damage. Wind gusts in excess of 70 mph were
        reported at Valmont and Boulder Airport. Chinook wind
        gusts to 60 mph briefly reduced the visibility to 1/4 mile
        in blowing dust at Stapleton Airport.
      In 1989... the season's greatest snowfall to date hit Metro
        Denver with 6 to 12 inches of snow. Flight delays at
        Stapleton International Airport reached 2 hours. Multiple
        wrecks snarled traffic on I-25 both north and south of the
        city. Snowfall totaled 7.0 inches at Stapleton
        International Airport where north winds gusted to 25 mph
        on the 10th.
