...Today in metro Denver weather history...

11-13 In 1892...from the 11th to the 13th...apparent post-frontal
        rainfall totaled 3.33 inches in downtown Denver over the
        3-day period.  A trace of snow on the 12th melted as it
        fell.  Rainfall of 2.58 inches on the 12th into the 13th
        was the greatest 24-hour precipitation ever recorded
        during the month of October.  Northwest winds were
        sustained to 48 mph with gusts as high as 55 mph on
        the 12th.
12-13 In 2001...overnight from the 12th to the 13th...peak wind
        gusts to 82 mph and 70 mph were measured atop Niwot
        Ridge and Squaw Mountain...respectively.
12-14 In 1969...from the 12th to the 14th...record breaking
        extremely cold temperatures for so early in the season
        occurred.  The high temperature of 26 degrees on the 13th
        was two degrees lower than the previous record minimum
        temperature of 28 degrees for the date set in 1885.  The
        high temperature of 24 degrees on the 12th exceeded the
        record low temperature (22 degrees set in 1885) for the
        date by only 2 degrees.  In addition...3 new record low
        temperatures for the dates were set.  The low
        temperature dipped to 10 degrees on the 12th breaking
        the old record (22 degrees in 1885) by 12 degrees.  On
        the 13th the mercury plunged to a low of 3 degrees
        breaking the old record (28 degrees in 1885) by 25
        degrees.  On the 14th the temperature reached a minimum
        of 4 degrees breaking the old record (25 degrees in 1966)
        by 21 degrees.
13    In 1990...strong downslope winds stirred up clouds of dust and
        gravel...rattled windows...and stripped autumn-colored leaves
        from trees in Boulder.  A wind gust to 78 mph was clocked
        in southwest Boulder...while a 96 mph gust was recorded in
        northwest Boulder.  West winds gusted to only 36 mph at
        Stapleton International Airport.
13-14 In 1910...the 13th through the 14th...light smoke from nearby
        forest fires drifted over the city.
      In 1966...the first measurable snow of the season caused
        widespread damage to trees and shrubs.  The heavy wet snow
        totaled 6.9 inches at Stapleton International Airport
        where north-northwest winds sustained at 20 to 25 mph and
        gusting to 45 mph caused much blowing and drifting snow.
        South and east of Denver...up to a foot of snow fell.  Heavy
        wet snow accumulations followed by freezing temperatures and
        strong winds resulted in extensive damage to trees...cars...
        and utility lines by falling limbs.  A woman was killed by
        a falling snow laden tree limb in Denver.  Several other
        people received minor injuries from falling tree limbs.
      In 1987...rain drenched metro Denver.  The South Platte Canyon
        area southwest of Denver received the most with 1.11
        inches at Kassler and 1.49 inches upstream at Strontia
        Springs.  At Stapleton International Airport...0.62 inch
        of rain was measured...northwest winds gusted to 29 mph...and
        thunder was heard.
      In 2007...a new 24-hour record of 2.65 inches of precipitation
        was set at Denver International Airport for the month of
        October; breaking the previous record of 2.58 inches set in
        1892.
13-16 In 1873...the 13th through the 16th...smoke from several large
        forest fires in the mountains made the air very hazy in the
        city.
