... This week in Metro Denver weather history...

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.
31-8 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.
1-9 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
        Denver.
5-11 in 1978... the 5th marked the start of a record 7 consecutive
        days of dense fog at Stapleton International Airport. The
        heavy fog reduced the visibility to 1/4 mile or less for a
        period of time on each of these days. Light snow and/or
        freezing drizzle occurred on most days. Fog reducing
        visibility to less than 7 miles was recorded at Stapleton
        International Airport on 11 consecutive days through the
        15th. During the period 5-14... the cold thick fog deposited
        heavy rime ice up to 5 inches thick on power lines and poles
        over a wide area of eastern Colorado... causing a major
        electrical power outage disaster.
6-7 in 1929... 5.0 inches of snow fell in downtown Denver behind
        a Canadian cold front. Temperatures plunged... but no records
        were set. Low readings dipped to 3 degrees below zero on
        the 6th and 9 degrees below zero on the 7th. Highs climbed
        to 5 degrees on the 6th and to only 1 degree below zero on
        the 7th.
      In 1933... Post-frontal light snowfall totaled 3.0 inches over
        downtown Denver. Northeast winds were sustained to 28 mph
        with gusts to 32 mph on the 6th. The very cold air mass
        plunged temperatures from a high of 60 degrees on the 5th
        to lows of 10 degrees below zero on the 6th and 16 degrees
        below on the 7th. High temperature of only 4 degrees below
        zero on the 7th was a record low maximum for the date.
6-10 in 1933... 3:00 PM on the 6th marked the start of a protracted
        cold period through 8:00 am on the 10th when the temperature
        was below zero for 86 out of 88 hours. The cold period was
        interrupted on the 8th at 9:00 am when the temperature was
        1 degree above zero and at 10:00 am when the temperature was
        8 degrees above zero. Four temperature records were set.
        High temperatures of 4 degrees below zero on the 7th... 8
        degrees on the 8th... and 5 degrees below zero on the 9th were
        record low maximums for those dates. The only record low
        temperature record was 14 degrees below zero on the 10th.
