... Today in Metro Denver weather history...

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.

        records began back in 1872. The average temperature for
        the month was 75.0 degrees which was 7.6 degrees above
        normal. There were a total of seventeen 90 degree days in
        the month of June. The highlight of record setting month
        was a stretch of five consecutive 100 degree days from the
        22nd to the 26th. This was only the third time in Denver
        weather history in which this happened. Two of the high
        temperatures during the stretch peaked at 105 degrees...
        which set the all time record for the month of June and
        tied the all time maximum temperature for Denver.
2-4 in 1989... 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
2-7 in 1921... heavy rainfall for nearly a week... 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

        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.

      In 1961... torrential rains fell 10 to 30 miles north of

        sending a 5-foot wall of water into the town... flooding
        homes and damaging sewer lines... roads... and streets.
        Golf Ball size hail fell in Derby... west Denver... and
        Lakewood... causing more than one million dollars in damage.
      In 1981... severe thunderstorms produced tornadoes over Metro
        Denver. The first tornado touched down at the intersection

        along Sheridan Blvd... .damaging businesses... apartment
        buildings... homes... and vehicles. Over ten homes were
        unroofed. The roof of one landed in the middle of a
        Neighborhood Park. At least 10 Mobile homes were wrecked.
        The tornado curved to the northeast into northwest Denver...
        hopping up and down in several places. Very strong winds
        outside the actual funnel caused 20 to 30 thousand dollars
        in damage in downtown Denver. The third floor of one old
        building was demolished. No major injuries were reported
        from the tornado... although several people were Hurt
        slightly in traffic accidents on Sheridan Blvd. In the
        confusion caused by the storm. Damage in Lakewood alone
        was estimated at 200 thousand dollars. At the same time...
        the worst tornado to ever hit Metro Denver struck Thornton.
        Coming from the same thunderstorm that spawned the Denver
        twister... the Thornton tornado tore a swath through The
        Heart of the city. 87 homes were destroyed... 110 others
        damaged at least moderately. In all... 600 homes in a 100
        block area sustained some damage. The twister also hit
        shopping centers... several restaurants... and other buildings.

        was strong enough to snap lamp posts in half and drive a 6-
        inch slab of wood 2 feet into the ground. Damage was
        estimated at up to 50 million dollars. The same storm that

        touched down in the northwest section of Fort Lupton. This
        twister damaged 16 homes and numerous cars and campers.
        Two children were slightly injured when the car they were
        in was knocked about and its windows shattered by the

        damage was estimated at 500 thousand dollars. The
        thunderstorm complex that produced 3 damaging tornadoes
        also dropped large hail which damaged many cars over
        northwest Denver. One to 2 inches of rain fell in less
