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

8-13  In 1875...clouds of grasshoppers were seen flying through
        the air on the prevailing winds during each day.
11    In 1872...fog was very dense until about 8:00 AM.  There was
        water dripping from the roofs of houses as if it had rained.
        The rain gage showed 0.01 inch of moisture...even though
        there had been no rainfall.
      In apparent dry microburst produced only a trace
        of rain and brief northwest winds sustained to 34 mph
        with gusts to 44 mph.
      In 1980...hail up to golf ball size caused some roof and car
        damage in the southern part of Aurora.
      In 1990...lightning ignited a storage tank filled with 10
        thousand gallons of crude oil in a farmer`s field near
        Dacono...25 miles north of Denver.  Flames shot to 40 feet
        high for nearly 2 hours before being extinguished.  A
        lightning bolt also struck 21 miles north of Denver at an
        Erie fire station...causing extensive damage to the gas meter
        and electrical system.  The sudden power surge blew out the
        station`s television set...a refrigerator...and a pop
        machine.  Small fires spread throughout the structure...
        totally destroying the building`s electrical wiring.  The
        fires were quickly extinguished by the in-resident fire
        fighters.  Golf ball size hail was reported in Denver near
        the intersection of Santa Fe Drive and I-25.
      In 2012...a severe thunderstorm produced a wind gust to 60
        mph at Rocky Mountain Metropolitan Airport.
      In 1992...dime size hail fell in Westminster.
      In 1994...strong thunderstorms produced large hail across
        northwest and north metro Denver.  One inch diameter hail
        fell in Brighton with 3/4 inch hail reported in Westminster
        and at Indian Hills in the foothills west of Denver.
        Lightning struck a house in Arvada.  The resulting
        fire destroyed one-third of the house.  Funnel clouds were
        sighted over Westminster.
      In 1997...large hail...strong winds...and torrential rains
        hammered portions of Lakewood and south Denver.  Nearly
        1 inch of rain fell in the span of 10 minutes in south
        Denver with a storm total of 1.81 inches.  Street flooding
        was extensive as gutters and other drainage systems in the
        area were clogged by hail...piled several inches deep...and
        other debris.  Strong thunderstorm winds to 50 mph and
        large hail accompanied by heavy rain caused extensive
        damage to businesses.  Several trees were
        downed by the strong winds...and trees were stripped of
        their leaves by hail.  A water lily exhibition on display
        at the Denver Botanic Gardens was heavily damaged.  Final
        estimates of the damage included 60 million dollars to
        automobiles and an additional 68 million dollars to homes
        and businesses.  Hail to 1 1/2 inches in diameter fell in
        south Denver with 3/4 to 1 inch hail in Lakewood.  A man
        received minor injuries in Aurora when he was struck by
        lightning while talking on the telephone.
      In 2003...hail to 3/4 inch in diameter was measured in Aurora
        near Cherry Creek.
