...This week in metro Denver weather history...

29-2  In 1990...almost a year to date after the record breaking heat
        in early July 1989...the third longest heat wave in Denver
        history started.  From June 29th through July 2nd the
        temperature reached 100 degrees or more on four consecutive
        days.  The highest reading of 102 degrees occurred on the
        29th...30th...and 1st.  Combined with the 102 degree reading
        on June 27th this would have been the longest heat wave on
        record...but the temperature climbed to only 98 degrees on
        June 28th.
29-15 In 2000...the 29th marked the beginning of a near record hot
        streak for metro Denver.  The high recorded
        at Denver International Airport...exceeded the 90 degree mark
        for 17 consecutive days from June 29th through July 15th.

        set from July 13th through August 5th...2008.
1-18  In 1874...a streak of 18 consecutive days of 90 degrees
        tied for second with another streak that was later set
        in the summer of 1901. The record of 24 consecutive days
        was established in the summer of 2008.
1-31  In was the hottest July on record in Denver since
        weather records began in 1872.  The average temperature for
        the month was 78.9 degrees which was 4.7 degrees above
        normal. There were 27 days in which the high temperature
        equaled or exceeded 90 degrees...which established a new
        record.  There were also 7 days in which the temperature
        equaled or exceeded 100 degrees which tied the record
        set in 2005.
2     In 1879...a severe hail storm produced considerable damage
        in the vicinity of Arvada.  Some of the stones were
        unusually large...measuring 6.5 inches in circumference
        (2 inches in diameter) with an average weight of 1 ounce.
        The stones were uniformly large with one side concave.
        The greatest damage was to early wheat...cabbage...and vines.
        A tree just to the south of the weather station in downtown
        Denver was struck by lightning.  Residents in the house
        15 feet away were affected by the strike.

        recorded at Stapleton Airport where the brief strong wind
        reduced the visibility to zero in blowing dust.
      In 1965...hail...up to 2 inches in diameter...struck southwest
        Adams and northeast Denver counties...damaging
        and foliage.  Hail accumulated up to a foot deep.  Wind
        gusts to 48 mph and hail to 1 inch in diameter fell at
        Stapleton International Airport where the large hail broke
        three storm windows and shredded shrubs at the U.S. Weather
        Bureau upper air building.

        County about 30 miles east of Denver.
      In 1987...a large tornado touched down 10 miles northeast of
        Stapleton International Airport.  The tornado was vertical
        and thick and kicked up a large dust and debris cloud. developed a sinuous rope-like shape as it slowly
        dissipated.  The tornado was visible for 15 minutes.  The
        twister occurred in open country and did only minor damage
        to a metal shed...porch...and mailbox.  A man was killed by
        lightning in southwest Aurora.  He was in his backyard and

        minimum for the date.
      In 2006...lightning struck a teenager in Castle Rock as he
        was mowing his lawn and listening to an iPod.  The teen
        suffered burns to his hands and feet...and had blood

        eardrums were ruptured...which damaged his hearing.
        Lightning also struck a house in Castle Rock causing
        extensive damage to the roof and side of the home.
        Heavy rains caused flash flooding at Castlewood Canyon
        State Park near Franktown.  The floodwaters destroyed
        four footbridges along the high trail.  A culvert and
        several roads were washed out in the area.  In addition...
        two driveways crossing Cherry Creek were washed out near
        Prairie Canyon Ranch.  Heavy rainfall also caused minor
        flooding on Murphy and Sand Creeks...just east of Buckley
        AFB.  Gun Club Road was closed between Alameda and
        Mississippi Avenues...north of the Murphy Creek Golf
        Course...where 3 feet of standing water reportedly covered

        driven hail as large as golf balls and heavy rain which
        caused flooding.  Winds were estimated at 60 to 70 mph.
        Rainfall was estimated at 2 to 3 inches.  Hail accumulated
        3 to 4 inches deep in some sections.  Hail carried by flood
        waters drifted 3 to 4 feet deep.  An Englewood policeman was
        injured when hail broke the windshield of his car.  One inch
        of rain in 10 minutes...and heavy hail damage were reported in
        Parker.  At some places the hail from the storm was still on
        the ground the next morning.
      In 1967...large hail stones from 1 3/4 to 2 1/2 inches in
        diameter damaged cars and buildings in southwest Denver and
        Littleton where hail drifted to depths of 3 to 4 feet.  The
        hail caused a great deal of damage...and streets were flooded
        by heavy rain over many sections of west metro Denver.  At
        Centennial Race Track near Littleton...a few hail stones
        were as large as tennis balls.  Large hail broke the

        reportable damage.
      In 1993...high winds developed behind a strong cold front along
        portions of the Front Range.  While the strongest winds were
        reported north of metro Denver...the winds blew out a half
        inch thick pane of glass from a vacant 9-story building.

        forest access roads as well...generally to the east of a line
        extending from Signal Butte to Deckers.
      In 2010...intense thunderstorms produced torrential rainfall...
        in excess of 5 inches in one hour...and caused flash flooding
        in the vicinity of Elizabeth.  Numerous county roads were
        washed out.  The combination of heavy rain and hail made it
        necessary to run snow plows through town.  Extensive
        basement flooding was also reported.  Severe thunderstorms
        produced large hail from Aurora south to Elizabeth and
        Larkspur.  The hail size ranged from 1 to 2 inches in
        diameter.  A wet microburst produced 1.84 inches of rainfall
        at Denver International Airport.  A peak wind gust to 48 mph

        on 5 consecutive days.  The city had previously never
        recorded more than 2 straight 100-degree days since records
        began in 1872.  Water and electricity usage reached all time
        highs.  The heat wave created extremely dry weather
        conditions...which contributed to a major forest fire in
        Boulder Canyon on July 9th.  The temperature reached 103
        degrees on the 8th...and the mercury climbed to 101 degrees
        on both the 4th and 5th...and to 102 degrees on both the

        on Bear Creek resulting in 7 deaths.  Flooding in Morrison
        was compounded when a wall of water as high as 15 feet
        swept down Mount Vernon Creek.  The flooding caused
        extensive damage to the Bear Creek Canyon highway.
      In 1959...wind gusts to 45 mph at Stapleton Airport...but higher

        buildings were flooded by the heavy run-off.  Hail in some
        areas contributed to flooding by blocking storm drains.
        Water accumulated 12 to 14 feet deep in several underpasses
        and some street intersections.  A young woman drowned when
        she tried to cross a flooded street and was swept off her

        southwest metro Denver...100 to 150 homes were flooded.
        Hail caused damage in other areas of Denver and in Aurora.
        Wind toppled trees in several areas.  Snowplows were called
        out to clear hail from some highways and runways at
        Stapleton International Airport.  Lightning damaged trees
        and power lines and started a fire...which extensively
