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

19-30 In 1875...grasshoppers appeared in great numbers at 10:00 AM
        on the 19th.  Thousands landed on the ground.  The streets
        were literally covered with them.  Swarms of grasshoppers
        were seen on each day.  All gardens in the city were
        devastated...and in the countryside the grasshoppers were
        very destructive to ripened grain.  On the 30th the
        grasshoppers were so numerous as to almost darken the sun.
22-24 In 1987...some locations in metro Denver had a total 3-day
        rainfall of 2 to 4 inches.  Rainfall totaled 0.96 inch
        at Stapleton International Airport.
24    In 1880...a thunderstorm produced vivid lightning and heavy
        rainfall...which caused flooding over the eastern part of
        the city including the brick yards.  There was no rainfall
        recorded in downtown Denver.
      In apparent dry cold front caused a remarkable drop
        in temperature.  From 3:00 PM until midnight the temperature
        fell from a high of 93 degrees to a low of 40 degrees.
        Northeast winds were sustained to 44 mph during the late
      In 1946...heavy rain near Idledale caused flooding on Bear
        Creek at Morrison...which resulted in one death when a
        woman was swept from her stranded car and drowned.
      In 1973...strong winds blew down a few power lines and hail up
        to 3/4 inch diameter fell in southeast Aurora.
      In 1984...heavy rain hit the south Denver area.  Over an inch
        fell in less than an hour at both Castle Rock and Sedalia.
      In 1992...heavy rains caused flash flooding across parts of
        metro Denver.  Rainfall amounts of 1 to 3 inches fell with
        the hardest hit areas being the southwest and central parts
        of metro Denver.  Bear Creek rose above bankfull near
        Idledale with flood waters moving into southwest metro
        Denver.  Mud and rock slides along Colorado Highway 74 west
        of Morrison were reported.  The confluence of Cherry Creek
        and the South Platte River in downtown Denver also went out
        of its banks...flooding bike paths.  Rainfall totaled 1.98
        inches at Stapleton International Airport where light to
        moderate rain fell most of the day.  Heavy rain and fog
        briefly reduced the surface visibility to 1 1/2 miles.  The
        temperature climbed to a high of only 58 degrees...which was
        a record low maximum for the date.
      In 2002...hail to 7/8 inch in diameter was measured in
        southwest Denver.
      In 2008...several landspout tornadoes developed along a boundary
        to the southeast of the Denver metropolitan area during the
        Democratic National Convention.  In northwest Elbert County...
        minor damage was reported.  The damage consisted of downed
        power lines...broken windows and an out building.  Severe
        thunderstorms also produced very heavy rain and large hail...
        up to one inch in diameter.  In southwest Douglas County...
        heavy rain caused flash flooding near the town of Westcreek.
        A mudslide closed State Highway 67.  The road in the YMCA Camp
        Shady Brook was also washed out and some bridges were damaged.
24-26 In 1910...the lowest temperature ever recorded in August...40
        degrees...occurred on each of these days and on August 22...
        1904.  The unusually cold weather for so early in the
        season brought sub-freezing minimum temperatures to much
        of the Colorado northeastern plains.
