...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

      In 1957...a vigorous cold front produced a dust storm as it
        moved south across metro Denver.  West-northwest wind gusts
        to 59 mph were recorded at Stapleton Airport where the
        surface visibility was briefly reduced to 1/2 mile in
        blowing dust.  Light snowfall of only 0.8 inch followed
        the passage of a secondary Canadian cold front.

        gusts of 70 to 80 mph were common in Boulder.
      In 1988...4 to 8 inches of snow fell across metro Denver and
        caused traffic gridlock conditions on area highways.  The

        two-hour flight delays.  Northeast winds gusted to 25 mph.
      In 2005...a brief cold snap resulted in record breaking
        temperatures.  The low temperature of 13 degrees below zero
        was a record minimum for the date.  The high temperature of
        only 3 degrees was a record low maximum for the date.  The
