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

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.
15-16 In 1928...a thunderstorm produced hail shortly after midnight
        on the 15th.  Rain changed to snow by evening.  Through the
        afternoon of the 16th...the heavy snowfall totaled 7.3 inches
        in the city.  North winds were sustained to 23 mph on the
        15th.
      In 1984...the heaviest October snowstorm in several years hit
        eastern Colorado with a vengeance.  The storm was known as
        the "Bronco Blizzard" since it occurred during a nationally
        televised Monday night football game in Denver; they held
        on and defeat Green Bay by a score of 17-14.  One to two
        feet of snow fell near the foothills in west metro Denver
        with 2 to 3 feet in the foothills.  Wind gusts up to
        55 mph whipped the snow into drifts as high as 4 feet.
        The storm closed schools...roads...and airports.  I-70
        was closed both east and west of Denver.  I-25 was closed
        south to Colorado Springs.  Flights were delayed for
        several hours at Stapleton International Airport.  Power
        outages were widespread.  Snowfall totaled 9.2 inches at
        Stapleton International Airport where north winds gusting
        as high as 40 mph caused frequent surface visibilities of
        1/4 to 1/2 mile in moderate to heavy snow and blowing snow
        overnight.  The high temperature of only 35 degrees on the
        15th was a record low maximum for the date.
15-17 In 1989...the 15th to the 17th...an autumn snowstorm hit metro
        Denver with 2 to 6 inches of snow.  Snowfall totaled 4.4
        inches at Stapleton International Airport where the
        maximum snow depth on the ground was only 3 inches due to
        melting and north winds gusted to 25 mph on the 15th.  The
        heavy wet snow caused leafy branches to sag onto power
        lines...resulting in a number of power outages.  Five
        thousand homes were blacked out in Boulder on the 16th.
        Up to a foot of snow fell in the higher foothills with 19
        inches recorded at Echo Lake.
16    In 1878...high winds reached sustained speeds of 60 mph.
      In 1998...one of the costliest hail storms to ever hit metro
        Denver caused an estimated total of 87.8 million dollars in
        damage to homes...commercial buildings...and motor vehicles.
        At the time the storm was ranked as the 7th costliest ever.
        The hailstorm...rare for so late in the season...began over
        portions of Arvada...Wheat Ridge...and northwest Denver
        where mostly pea sized hail accumulated up to a depth of
        6 inches near I-70.  Several accidents were attributed...
        at least in part...to the hailstorm.  Snowplows had to be
        called out to clear several city streets.  The storm
        intensified as it moved to the east...into the Denver and
        Aurora areas.  Large hail...up to 2.00 inches in diameter
        pounded east and southeast metro Denver.  Two inch diameter
        hail fell in the City of Denver and at Buckley Field.  Hail
        as large as 1 1/2 inches was measured in south Denver with
        1 inch diameter hail in northern Aurora.
      In 1999...upslope conditions produced snow across metro Denver
        with heavy amounts in the nearby foothills.  Snowfall totals
        included:  9 inches at Eldorado Springs; 8 inches at Genesee...
        Golden Gate Canyon...Littleton and near Morrison; 7 inches
        near Nederland; and 6 inches in Louisville.  Snowfall
        totaled 3.6 inches at the site of the former Stapleton
        International Airport.
16-17 In 1990...strong downslope winds raked the eastern foothills.
        Wind gusts from 60 to 75 mph were common.  Strong winds in
        metro Denver resulted in wave damage to a dock used to moor
        several private sail boats at Cherry Creek Reservoir.
        Damage was confined to the dock and two anchor cables.
        A northwest wind gust to 43 mph was recorded at Stapleton
        International Airport.
