        inch hail measured in Brighton.  Thunderstorm winds gusted
        to 69 mph at Bennett.  The strong winds were responsible
        for flipping three semi-trailer trucks onto their sides
        along I-70...3 miles east of Bennett.  A few cars were also
        overturned.
      In 2001...heavy thunderstorm rain caused flash flooding over
        south metro Denver.  Three inches of rain reportedly fell
        near the Greenwood Village Police Department in the span
        of 15 minutes.  The heavy rain caused Toll Gate Creek to
        overflow...flooding low lying areas along Parker Road.
        Heavy rainfall also caused local flooding along streets
        near the Denver Technology Center.  A severe thunderstorm
        dumped hail to 1 3/4 inches in diameter near Castle Rock.
      In 2003...maximum temperature of 100 degrees was a record high
        for the date.
      In 2009...severe thunderstorms produced wind gusts to 70 mph
        near Parker and Strasburg.  At Denver International
        Airport...west-northwest winds gusted to 40 mph.
      In 2011...severe thunderstorms produced extensive damage as
        they moved across the Urban Corridor. At Denver
        International Airport alone...large hail up to 1 3/4 inches
        in diameter...very heavy rain and wind gusts to 59 mph caused
        substantial damage to 40 planes and stranded approximately
        1500 passengers overnight. Frontier and United Airlines
        were hardest hit as dozens of planes were taken out of
        service for repairs; forcing the cancellation of at least
        220 flights over the next several days. Damage to the
        aircrafts alone was nearly five million dollars. In
        addition...83 cars in airport parking lots were damaged...
        along with some police cars and maintenance vehicles. In
        Watkins...two people suffered minor injuries and 35 to 40
        homes were damaged. As many as two hundred residents in a
        mobile home park were left homeless by the storm...forcing
        the Red Cross to open a shelter at Bennett High School.
        The trailer park contained 52 mobile homes...14 recreational
        vehicles...3 houses and a commercial building. Hailstones
        the size of softballs cratered the north sides of the
        mobile homes. Some farmers in the area said they lost as
        much as 85 percent of their total wheat crop. Power lines
        were also damaged which affected about 1200 customers in
        Watkins. The strong winds also flipped over a tractor-
        trailer rig on I-70 near Watkins Road. Insurance claims for
        the Watkins...Bennett and Brighton areas was estimated to be
        seventeen million dollars. The total damage estimate across
        the entire Urban Corridor...was near one hundred sixty five
        million dollars...and included 17200 automobile claims and
        12600 homeowner claims. In addition...thunderstorms
        producing very heavy rainfall...caused flash flooding in the
        Four Mile Canyon burn scar west of Boulder. Three homes
        reportedly had water up to the windows with water flowing
        into structures at Fourmile Canyon Road and Gold Run Road.
        The heavy rain caused a 4-ft surge along Fourmile Creek
        through Orodell and into the entry of Boulder Creek.
        Several roads were affected which restricted access to the
        area. Roads were closed due to water and debris. Private
        bridges and drives were washed out and several residents
        were stranded and later rescued. Numerous cars were damaged
        in debris flows and several structures suffered flood
        damage but were not destroyed.
      In 2019...a severe thunderstorm produced hail up to 1.0 inch
        in diameter in Broomfield...with 7/8 inch size hail reported
        in Arapahoe County near Buckely AFB.
13-5  In 2008...a streak of 24 consecutive days of 90 degrees...from
        July 13th to August 5th...shattered the previous record of 18
        consecutive days established in 1901 and 1874. Ironically...
        no new single day record high temperatures were set in the
        month of July. In August however...a record of 104 degrees
        was set on the 1st...and another record of 103 degrees was
        set on the 2nd. In addition...a record low min of 70 degrees
        was set on August 2nd.
