...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.

        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
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

        a low of 2 degrees below zero.
      In 1984...up to 6 inches of new snow fell over metro Denver...

        snowfall totaled only 4.1 inches at Stapleton International
        Airport...7 inches of new snow fell in Morrison...with 12
        inches measured in Castle Rock.  North winds gusted to
        23 mph at Stapleton International Airport on the 13th.
      In 1995...strong winds gusting to nearly 100 mph whipped
        across the foothills west of Denver.  The strongest wind
        gusts included 98 mph atop Squaw Mountain and 75 mph at
        the Eldora Ski Area.  West-northwest winds gusted to 41
        mph at Denver International Airport on the 13th.
12-15 In 1921...downslope chinook winds produced warm temperatures
        in the city...which resulted in 4 temperature records.
        High temperatures of 72 degrees on the 13th and 68 degrees
        on the 15th were record maximums for the dates.  Low
        temperatures of 47 degrees on both the 12th and 13th were
        record high minimums for the dates.  West winds were
        sustained to 38 mph on the 12th and to 25 mph on the
13    In 1955...strong winds raked the foothills.  A wind gust to 72

      In 1987...a snowstorm dropped 2 to 8 inches of snow along the
        Front Range foothills.  Eight to 12 inches fell just south

        traffic accidents across metro Denver and flights were
        delayed at Stapleton International Airport where 2.7
        inches of snow fell and northeast winds gusted to 17 mph.
      In 1991...high winds pummeled metro Denver.  Wind gusts to 93
