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

1-2   In 2002...unusually very warm weather for so early in June
        resulted in two temperature records.  Maximum temperatures
        of 96 degrees on the 1st and 93 degrees on the 2nd were
        record highs for each date...respectively.
1-4   In 1977...unusually warm weather for this early in June
        resulted in 3 maximum temperature records being equaled
        at the time:  88 degrees on the 1st...90 degrees on the 2nd...
        and 93 degrees on the 4th.  Maximum of 91 degrees on the
        3rd was not a record.
2    In 1914...flooding occurred on Boulder Creek when heavy rains
        added to heavy snowmelt runoff.  Flooding damaged the water
        supply system from the mountains into Boulder and destroyed
        roads and bridges in the canyons above Boulder.  The
        flooding in central Boulder was described as the worst
        since the tragic flood of May 29th through June 3rd in
        1894.  However...there was no reported loss of life.  The
        flood waters also inundated pasture land to the east of
        the town.
      In 1951...the lowest recorded temperature in June...30 degrees...
        occurred. The unusually cold weather was accompanied by
        0.3 inch of snowfall.  Precipitation...both rain and
        melted snow...totaled 0.30 inch.
      In 1966...microburst winds gusted to 51 mph at Stapleton
        International Airport.
      In 1981...a severe thunderstorm roared through metro Denver...
        dumping 2.00 inches of rain in as little as 20 minutes and
        bombing many areas with hail to 1 3/4 inches in diameter.
        The heavy rain caused local flooding with up to 3 feet of
        water in some streets in northwest metro Denver.  Part
        of a street was washed out in Thornton.  Lightning strikes
        started a fire and caused a power outage just north of
        Denver.  Lightning also struck a barn which burned to the
        ground in Brighton.  Numerous cars sustained minor hail
        damage.  A tornado was spotted 4 miles northeast of the
        Rocky Mountain Arsenal...but caused no damage.
      In 1982...severe thunderstorms produced large hail across
        metro Denver.  Hail to 3/4 inch in diameter was reported in
        Louisville and northeast Denver.  Golf ball size hail fell
        near Strasburg where two tornadoes were also sighted.
      In 1983...a tornado touched down 5 miles south of Bennett.  It
        destroyed an outbuilding and did extensive damage to
        greyhound dog shelters.  Golf ball size hail fell near the
        tornado...destroying some hay.
      In 1985...3/4 inch hail fell in southwest metro Denver.
      In 1989...large hail fell over eastern and central Denver.  A
        few stones were as large as baseballs...and many ranged from
        3/4 inch to golf ball size.  The hail piled up 2 to 4 inches
        deep in some areas.  Hail to 3/4 inch fell at Buckley Field
        in Aurora...and 7/8 inch hail fell just east of Aurora.  A
        home in Louisville was struck by lightning and was 30
        percent destroyed by the ensuing fire.
      In 1991...strong thunderstorm winds in Arapahoe County...14
        miles southeast of Stapleton International Airport...damaged
        the roof of a home and a radio antenna.  A funnel cloud...
        4 miles northeast of Stapleton International Airport...was
        sighted for 11 minutes by National Weather Service
        observers.
      In 1993...a tornado touched down briefly in south Denver...
        destroying the 4-inch thick concrete roof of a building and
        causing about 20 thousand dollars in damage.  The twister
        also picked up a trash dumpster and dropped it onto a car
        30 feet away...causing an estimated 3 thousand dollars in
        damage.  Hail up to an inch in diameter fell in Aurora...
        Conifer...and Bennett.  Two funnel clouds were spotted near
        Deckers.  A funnel cloud was sighted for 19 minutes by
        National Weather Service observers to the southwest of
        Stapleton International Airport.
      In 1994...lightning struck two homes in Denver...starting
        fires which caused considerable damage to both.  Hail to
        3/4 inch in diameter fell in Golden.
      In 1995...lightning struck a house in Nederland...causing a
        fire that was doused by subsequent rainfall.  A portion
        of the roof and wall was damaged.  The storm also left
        most of Nederland without power for two hours.  Lightning
        also struck a high chimney of an elementary school in west
        Denver.  The jolt sprayed bricks around the school yard and
        parking lot.  Twenty students and teachers were in the
        school building at the time...but all escaped without
        injury.  A funnel cloud was sighted over Fort Lupton...and
        3/4 inch hail fell in Lafayette.
      In 2003...severe thunderstorms produced strong winds and
        large hail.  Hail as large as 1 1/2 inches in diameter fell
        near Parker.  Estimated wind gusts to 70 mph occurred
        near Parker and near Denver International Airport where
        thunderstorm wind gusts to 52 mph were recorded.  Wind
        gusts to 60 mph were estimated near Bennett.
      In 2005...a severe thunderstorm produced hail as large as
        1 inch in diameter in the City of Denver.  A tornado
        was sighted near Bennett along with 3/4 inch hail.
      In 2008...severe thunderstorms produced large hail over
        western Arapahoe...northern Denver and southern Weld
        Counties.  Hail...2 inches in diameter...was observed near

        61 mph at Buckley Field...60 mph near Byers and southwest
        Denver...58 mph near Watkins and 52 mph at Denver
        International Airport.  The microburst winds caused
        extensive tree and roof damage.  In addition...hail up to
        1 inch in diameter was reported 3 miles east-southeast of
        Parker.
       In 2019...lightning struck a home in Broomield.  Minor
        damage to the roof was observed.
2-4   In 1989...from the 2nd to the 4th...heavy rain drenched metro
        Denver with the greatest amounts recorded on the 3rd.
        Total rainfall ranged from 1 1/2 to 3 inches.  Roads were
        washed out in Boulder County...and flooded basements caused
        water damage to houses in the Gunbarrel section of Boulder.
        In suburban Denver...heavy rain caused minor flooding along
        Lena Gulch in Jefferson County where two mobile home parks
        were evacuated. Rainfall totaled 1.66 inches at Stapleton
        International Airport.
2-7   In 1921...heavy rainfall for nearly a week...from the 2nd to
        the 7th...on top of streams already swollen by mountain
        snowmelt...produced widespread flooding over the South
        Platte River basin...including the tributaries through the
        canyons to the west and southwest of Denver.  Heavy
        rainfall over the 6-day period totaled 3.36 inches in
        Boulder...4.98 inches in Morrison...4.27 inches
        in Castle Rock...and 2.94 inches in the City of Denver.
        Rainfall amounts in the foothills were estimated between
        3 and 6 inches.  The narrow-gage tracks of the Colorado and
        Southern Railroad were destroyed in the Platte canyon.  From
        the mouth of the canyon through the city to near Brighton...
        the river spread from 1/2 to nearly 1 1/2 miles wide...
        flooding farm and pasture land and destroying or damaging
        many bridges.  In the city...many businesses along with as
        many as 500 homes were inundated...forcing their evacuation.
        Bridges were swept away.  The high waters flooded the rail
        yards and stock yards in lower downtown...closing three
        adjacent packing houses.  The heavy rains also caused
        flooding on Boulder Creek in Boulder on the 6th.
