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

11-13 In 1892...apparent post-frontal rainfall totaled 3.33
        inches in downtown Denver over the 3 days.  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 peak wind gusts to 82 mph and 70 mph
        were measured atop Niwot Ridge and Squaw Mountain...
12-14 In 1969...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...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
        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
