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

19-30 In 1875...grasshoppers appeared in great numbers at 10:00 AM
        on the 19th and continued through the 30th.  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.
24-26 In 1910...the lowest temperature ever recorded in August...40
        degrees...occurred on the 24th...25th and 26th...as well as 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.
26    In 1944...one of the most destructive hailstorms in the city
        in a decade caused damage estimated at nearly one million
        dollars.  The storm occurred within a period of 10 to 30
        minutes...between 2:00 PM and 3:00 PM.  The hail varied in
        size from very small to as large as 1 1/2 inches in
        diameter.  Hail covered the ground to a depth of 5 to 6
        inches in some sections of the city.  Several people were
        cut by broken glass.  The hail and heavy rain flooded
        underpasses to a depth of 6 feet...and the occupants of
        stalled autos had to be rescued.  Sewers were unable to
        handle the sudden amount of water and water backed up
        and flooded a number of basements.  A few first floors of
        buildings were flooded.  The Water Department had a busy
        time replacing manhole covers that had been displaced by
        the water pressure.  Trees were stripped...one was severely
        broken...and telephone lines were downed.  Roofs...windows...
        automobiles...awnings...and gardens were severely damaged.
        Flowers and gardens in some sections of the city were a
        total loss.  Greenhouses were extensively broken with an
        estimated 20 carloads of glass shattered.  Vegetable and
        truck crops in and around the city were severely shredded.
        The next day the American Red Cross was designated by the
        War Agency to grant any and all priorities needed to obtain
        materials and supplies to replace and repair the damage.
        In downtown Denver...the thunderstorm produced 0.95 inch of
        rain and heavy hail along with sustained northwest winds to
        25 mph.
      In 1961...strong winds blew in the walls of a warehouse under
        construction in Denver.  Two workmen suffered a fractured
        foot and body bruises.
      In 2014...two men in central Denver were struck by lightning as
        they sat under a tree to avoid a heavy downpour. One of the
        men was unconscious and had no pulse when emergency
        responders arrived. He was immediately taken to Denver
        Health was listed in critical condition. The other victim
        suffered less severe injuries. He was treated at the scene
        and hospitalized...then released a few hours later.
26-27 In 1980...overnight from the 26th to the 27th...two strong
        thunderstorms hit Arvada and Westminster...dumping up to 1.50
        inches of rain in less than an hour.  At least two streets
        were washed out and a number of homes and cars were damaged
        when a creek flooded.  Three homes in Arvada sustained minor
        lightning damage.
