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

29-15 In 2000...the 29th marked the beginning of a near record hot
        streak for metro Denver.  The high temperatures...as recorded
        at Denver International Airport...exceeded the 90 degree mark
        for 17 consecutive days from June 29th through July 15th.
        The record of 24 consecutive 90 degree or above days was
        set from July 13th through August 5th...2008.
1-18  In 1874...a streak of 18 consecutive days of 90 degrees...from
        the 1st to the 18th...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.
6-23  In 1901...from the 6th to the 23rd...a streak of 18 consecutive
        days of 90 degrees tied for second with another streak set
        in the summer of 1874. The record of 24 consecutive days was
        established in the summer of 2008.
7-25  In 1934...a streak of 15 consecutive days of 90 degrees...from the
        7th to the 25th...ranked 5th on the list of hot streaks.  The
        record of 24 consecutive days was established in the summer of
        2008.
9     In 1872...a very brisk wind between 2:00 PM and 3:00 PM
        spread a cloud of dust and sand into the city.
      In 1874...northeast winds at sustained speeds up to 36 mph
        blew immense clouds of dust from the prairie through the
        streets of the city around mid-morning.  The houses
        across the street from the weather station were not
        visible at the peak of the storm.
      In 1875...heavy thunderstorm rains caused stream flooding...
        which damaged nearly all railroads into the city.  Rainfall
        in the city was only 0.14 inch.
      In 1953...heavy thunderstorm rains caused an estimated
        2 million dollars damage from flooded stores and basements
        across metro Denver.  The flood waters reached a depth of
        3 feet on streets in some sections of the city...damaging
        streets and automobiles.  The heavy rainfall at Lowry Air
        Force Base totaled 3.90 inches.  At Stapleton Airport where
        the heavy rain briefly reduced the surface visibility to
        1/2 mile...only 1.05 inches of rain were measured.  North
        winds gusting to 52 mph caused some damage in east Denver.
      In 1982...two small tornadoes were spotted east of Rocky Flats...
        and a tornado touched down briefly 5 miles east of Brighton.
        No damage was reported.

        Denver.  Rainfall totaled 1.50 inches in just 15 minutes
        between Littleton and Sedalia.
      In 1987...a thunderstorm microburst produced a wind gust of 58
        mph at Erie north of Denver.
      In 1988...hail to 3/4 inch in diameter piled up 2 to 4 inches
        deep in Idaho Springs.  Some basements were flooded and
        several thousand gallons of fuel were contaminated when
        water flooded a gasoline storage tank.  A tornado sighted
        near Manilla 5 miles west of Bennett remained on the
        ground for 9 minutes.  No damage was reported.
      In 1990...a severe thunderstorm produced a tornado and heavy
        rain over northeast metro Denver.  As much as 4 inches of
        rain fell in just 20 minutes in Commerce City...causing the
        South Platte River to rise quickly and flood lowland areas.
        The raging flood waters caused extensive damage to a 30-foot
        stretch of railroad track embankment...destroyed a railroad
        trestle and a nearby garage...and washed away a vintage
        1960`s show car near east 58th Avenue and York Street.  The
        car was found a couple of miles downstream in a pool of deep
        mud and murky water.  Rainfall totaled 1.34 inches at
        Stapleton International Airport where 1/2 inch diameter hail
        fell.  The same thunderstorm produced a brief tornado in a
        vacant field near 64th Avenue and Tower Road just east of
        the Rocky Mountain Arsenal.  No damage was reported from the
        twister.  Lightning from the storm caused power outages to
        as many as 7 thousand homes and businesses.
      In 1996...a tornado (F0) was reported 5 miles south of Hudson.
        No damage was reported.  Twin weak tornadoes (F0) formed
        for a short time near the northeast runways at Denver
        International Airport.  Less than 15 minutes later...a weak
        tornado (F0) touched down in the employee parking lot at
        DIA.  Several car windows were blown out...and a few vehicles
        sustained minor body damage from flying debris.  Several
        signs were also blown down.  Later...twin weak tornadoes (F0)
        touched down again in open country between DIA and Watkins.
      In 2004...severe thunderstorms produced hail to 3/4 inch in
        diameter near Tiny Town and wind gusts to 66 mph in Bennett.
        A thunderstorm wind gust to 56 mph was measured at Denver
        International Airport.

        large hail over parts of Adams...Arapahoe...and Weld counties.
        The hail generally ranged from 1 to 1 3/4 inches.  The
        largest reports included 2 inch hail in Watkins...with 2 1/2
        inch hail...11 miles east of Arapahoe Park.  Near Brighton
        and Henderson...thunderstorm wind gusts up to 60 mph caused
        minor tree damage.  At Denver International Airport...a peak
        wind gust to 36 mph was observed from the northwest.  In
        addition...0.03 inches of rainfall was reported.
9-10  In 1980...from the 9th to the 10th...a series of severe
        thunderstorms hit metro Denver...dumping heavy rain and
        producing a spectacular lightning display lasting for several
        hours.  A number of homes were damaged by lightning.  Winds
        gusted to 60 mph at Stapleton International Airport where
        about half an inch of rain fell in just 10 minutes along with
        1/4 inch diameter hail.  The evening thunderstorms continued
        into the early morning hours with total rainfall of 1.35
        inches at Stapleton International Airport.
