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

16-19 In 1979...heavy thunderstorm rains on each of 4 consecutive
        days...the 16th through the 19th...dumped a total of 2.62
        inches of rain on Stapleton International Airport.  The
        heaviest rain...1.05 inches...on the 19th was accompanied by
        1/4 inch diameter hail.
18-19 In 1875...nearly 0.75 inch of rainfall in the city overnight...
        from the 18th to the 19th...possibly assisted by heavier
        rainfall upstream...produced a decided and rapid rise in
        Cherry Creek...which washed out some bridges.  Other small
        creeks and streams were filled to overflowing.
19    In 1983...heavy rain fell across the northern metro Denver
        suburbs with 1.50 to 1.80 inches of rain in Broomfield...
        Arvada...and Thornton.
      In 1989...lightning killed a 31-year-old man and injured his
        10 year old nephew when it hit a tree they were walking
        under in the foothills about 5 miles west of Boulder.  The
        boy received mouth to mouth resuscitation on the scene and
        recovered after being hospitalized overnight.  Three other
        people were knocked to the ground by the bolt...but were
        uninjured.
      In 1990...3/4 inch diameter hail was reported in Wheat Ridge.
        A thunderstorm over west Denver dumped an inch of rain in
        20 minutes...causing minor street flooding.  One inch
        diameter hail was reported over east Denver.  Ping pong to
        golf ball size hail was reported 14 miles northeast of
        Denver at the intersection of 122nd Ave. and Brighton Blvd.
        The hail stones knocked out windows and did an unspecified
        amount of damage to the roof of a house.  Close by...heavy
        thunderstorm rains caused gullies...irrigation ditches...and
        small streams to overflow their banks near the intersection
        of 120th Avenue and Riverdale Road.  Flood waters 1 to 2
        feet deep covered the river bottom land along the South
        Platte River.  However...no structures were threatened by
        the flood waters.
      In 1999...heavy rain...up to 5 inches in two hours...caused
        East Tollgate Creek to jump its banks.  The bike path
        adjacent to the creek was underwater at several locations.
        Several underpasses were also flooded...halting traffic.
        In addition...an unfinished playground at a local elementary
        school was completely flooded.  Lightning struck a vehicle
        at East Evans Avenue and Tower Road.  The woman inside the
        vehicle was not injured.
      In 2016...a severe thunderstorm produced a wind gust to 64 mph
        near Commerce City.
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.
