      In 2014...damaging hail...from 1 to 2 inches in diameter...
        caused extensive damage to homes and automobiles over parts
        of Arapahoe and Douglas Counties including areas in and
        near:  Aurora-Cherry Creek...Buckley Air Force Base...Denver
        International Airport and Parker.  Officially...0.06 inches
        of rain fell at Denver International Airport...with a peak
        wind gust of 33 mph from the southeast.
      In 2015...two colliding outflow boundaries merged over east
        Denver and northwest Aurora at the height of rush hour. The
        collision quickly spawned a severe thunderstorm that
        produced an EF1 tornado...damaging hail...torrential rain and
        flash flooding. The tornado touched down in east Denver and
        west Aurora. The tornado first touched down near Quebec and
        6th Avenue. It then moved east northeast across the Lowry
        Campus into the west part of Aurora. The tornado then lifted
        near Mount Nebo Memorial Park. Some homes had minor roof
        damage with one former apartment building on the Lowry
        Campus had more significant roof damage. The tornado and
        intense thunderstorm winds uprooted trees...damaging vehicles
        and blocking roads. The storm produced torrential rain...2.0
        to 2.5 inches...much of which fell in less than 30 minutes and
        resulted in flooded intersections and power outages. Flash
        flooding forced the evacuation of a theater at the Cherry
        Creek Shopping Center...where drifts of hail formed in the
        parking lot...and flooding set off alarms at the University
        of Denver`s Ritchie Center. Numerous water rescues were
        reported as vehicles stalled flooded intersections. Many
        stoplights were knocked out. The water was reportedly 3
        feet deep on the South Broadway ramp to Interstate 25. The
        bike path along Cherry Creek was inundated with several feet
        of water at the height of the storm. Ironically...it was
        "Bike to Work Day"...which made for a long commute home
        for many.  The South Platte River crested above flood stage
        for one hour. Employees still at work were urged to stay
        inside but others waded across flooded intersections
        downtown. About 30 flights had to be diverted from Denver
        International Airport.  At Denver International Airport...
        only 0.05 inches of rain fell.  A peak wind gust to 47
        mph was observed from the southeast.
25    In 1873...forest fires produced a great deal of smoke in the
        mountains to the southwest of the city.
      In 1958...an unusually cold day for summer set two temperature
        records for the date.  Under cloudy skies with occasional
        drizzle...a record low maximum temperature of 55 degrees was
        established along with a record minimum temperature of 42
        degrees.

        inches fell in Louisville.  A brief funnel cloud was
        sighted by National Weather Service personnel 4 miles east
        of Stapleton International Airport.
      In 1982...a bolt of lightning struck a cabin in the foothills
        west of Denver.  The resulting fire totally destroyed the
        cabin.

        A 25-year-old man was killed...and a 21-year-old man
        suffered extensive injuries.  Thunderstorm winds knocked
        over two elm trees near downtown Denver.  One fell on a
        house destroying most of it.  A nearby building was
        unroofed...and two cars were damaged.  A truck that had been
        severely damaged by one of the Denver tornadoes 10 days
        before was hit again.  Thunderstorm wind gusts to 51 mph
        were recorded at Stapleton International Airport.

        inches in diameter. At Denver International Airport...just
        a trace of rainfall was observed.  A peak wind gust of 31
        mph was also observed from the east.
25-26 In 1969...from the 25th into the 26th...high winds raked Boulder
        causing one fatality and some injuries.  One man was injured
        by a falling tree limb. At the National Center for
        Atmospheric Research in Boulder...sustained winds of 55 to 60
        mph with wind gusts to 123 mph were recorded.  In downtown
        Boulder...winds averaged 30 to 40 mph with gusts to 70 mph.
        Widespread minor damage occurred...especially in the Table
        Mesa area of south Boulder.  Much tree damage occurred in
        the older areas of Boulder where several trees were uprooted.
        A mobile home was overturned by the winds.  At Stapleton
        Airport...west winds gusted to 43 mph on the 25th and 37 mph

      In 1983...from the 25th into the 26th...heavy rain fell in the
        foothills west of Denver with 1.50 inches in 30 minutes at
        Intercanyon.  Heavy rain continued over metro Denver on the
        26th with two-day storm totals at many locations ranging

        airmass was unusually cold for the season...and snow fell in
        the foothills above 8 thousand feet.  The high temperature
        of only 63 degrees on the 26th equaled the record low
        maximum reading for the date.
      In 2012...Denver broke the all-time record temperature for the
        month of June on the 25th when it reached 105 degrees. This
        also tied the all-time record maximum temperature in Denver.
        The maximum temperature of 105 degrees was then matched once
        more on the 26th. Sandwiched in between these records...the
        minimum temperature of 71 on the morning of the 26th...

        the city.  New and extensive fires were continually started
        from south to northwest along the ridge line.  Carelessness
        of tourists was the apparent cause of the fires.  Large and
        valuable tracts of timber had already been destroyed.
      In 1890...the only thunderstorm of the month produced a trace
        of rain.  A trace of rain also fell on 7 other days.  This

        International Airport.
      In 2002...heavy rain...up to 3/4 inch...fell across sections of
        the Hayman burn area near Cheeseman Reservoir.  Several
        forest service roads were washed out and many culverts were
        plugged by debris.
      In 2004...heavy rain producing thunderstorms caused rock and
        mud slides across the Overland Fire burn area in Jamestown.
        An estimated 50 tons of sand...dirt...rock...and ash slid into
        town...filling a culvert under Main Street.  The slide covered
        150 to 225 feet of Main Street.  The flood was produced by
        half an inch of rain in 30 minutes.  A deluge of very heavy
        rainfall from nearly stationary thunderstorms caused flooding
        and flash flooding problems over parts of Jefferson and
        Douglas counties.  An automated rain gage in Golden measured
        3.60 inches of rainfall in one hour.  Numerous homes were
        flooded in Golden...including one that was 146 years old.
        The home was listed as a complete loss.  State Highway 93
        had to be closed from the Pine Ridge subdivision to the
        Golden Gate Canyon Road.   At the height of the storm...about
        4 feet of water covered State Highway 93 through Golden...
        forcing its temporary closure.  Several intersections were
        also flooded and impassable.  Rock and mud slides were
        reported in Golden Gate Canyon State Park.  At the Deer
        Creek Golf Course at Colorado 470 and Kipling...the greens

      In 1997...strong microburst winds of unknown speed downed
        several trees...signs...and at least one light pole in the
        Fort Lupton area.  Two trees knocked over by the storm
        downed power lines causing scattered outages.
      In 2002...a thunderstorm wind gust to 60 mph was recorded in
        Parker.
      In 2005...severe thunderstorms produced wind gusts to 66 mph
        near Longmont and to 60 mph near Niwot.  No damage was

        were transported from the trailhead...and three of those
        were taken to Denver-area hospitals. One was in serious
        condition...the other two had non-life threatening injuries.
        The strike also killed a dog. Severe thunderstorms produced

        Byers...and 1 1/4 inches in diameter...13 miles north of
        Elizabeth.
      In 2016...severe thunderstorms produced hail...from quarter
        to ping ball size...over northwest...west and southwest
        parts of Denver.  In addition hail up to quarter size was
        also reported just southeast of Denver International
        Airport. Officially only a trace of rainfall was measured
        at the airport...with a peak wind gust of 35 mph from the
        west.
29    In 1874...eight different fires in mountain forests were
        visible from the city.  All of the fires were extensive...
        and the volume of smoke from each was immense.  Three of
        these fires had been burning from the 18th with varied
        intensity.
      In 1911...an apparent dry microburst produced sustained winds
        to 45 mph.
      In 1960...a strong gust of wind blew a small foreign sedan off
        the highway near Brighton...injuring the driver.  East winds

        occurred over southeast Denver.  No significant damage was
        reported.
      In 1962...heavy rain and small hail caused some flooding in
        southwest Denver.
      In 1995...upslope cloudiness with rain and fog cooled
        temperatures to record levels.  Low temperature of 47
        degrees equaled the record for the date.  High temperature
        of only 54 degrees set a new record low maximum for the
        date.  Rainfall totaled 0.90 inch at Denver International
        Airport and 0.41 inch at the site of the former Stapleton
        International Airport.

        intense microburst with a peak wind gust of 74 mph east
        of Centennial near Smoky Hill.  At Denver International
        Airport...a peak gust to 34 mph was observed from the
        northwest.  Blowing dust briefly reduced the visibility to
        one half of a mile...along with 0.05 inch rainfall.
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 temperatures...as recorded
