...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
4-6   In 1960...heavy snowfall totaled 12.0 inches over the 3 days
        with 5.1 inches on the 4th...5.2 inches on the 5th...and
        1.7 inches on the 6th.  Rain changed to snow early on the

        on the 5th and continued through midday on the 6th.  West
        northwest winds gusted to 30 mph on the 4th.  Post cold

        of snowfall was not recorded...but precipitation from melted
        snow totaled 1.75 inches...which would give an estimated
        snowfall of nearly 18 inches.  Temperatures during the
        storm were in the 30` some of the snow may have melted
        as it fell.  However...railroads were blocked and telegraph
        lines were downed in all directions.  Telephone wires and
