...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.
4-8   In 1989...one of the most intense heat waves on record roasted
        metro Denver.  The temperature reached 100 degrees or more
        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
        6th and 7th.  The low temperature of 68 degrees on the 8th
        equaled the record high minimum for the date.
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.
8     In 1905...a thunderstorm produced 0.82 inch of rainfall and
        northeast winds sustained to 48 mph.
      In 1977...strong winds turned over 2 light aircraft at Arapahoe
        County Airport...now Centennial Airport.
      In 1987...a weak tornado was observed near Bennett.
      In 1988...three separate tornadoes were sighted near Bennett.
        No damage was reported.  One inch diameter hail was also
        reported.
      In 1991...lightning started three house fires in Castle Rock.
        Damage totaled 13 thousand dollars.  No injuries were
        reported.
      In 1993...a dry thunderstorm microburst wind gust to 55 mph
        briefly reduced the surface visibility to 3 miles at
        Stapleton International Airport.
      In 1997...one construction worker was killed and two others
        injured when a strong thunderstorm wind gust caused the
        scaffolding they were standing on to collapse near Parker.
        A dry microburst produced a wind gust to 54 mph at Denver
        International Airport.
      In 1998...heavy thunderstorm rain forced the closure of
        Hampden Avenue between I-25 and Havana Street in southeast
        Denver.  The high water made 2 or 3 lanes of the street
        impassable.
      In 2001...severe thunderstorms produced large hail...damaging
        winds...and heavy rain across south metro Denver.  Two
        people received minor injuries when a severe thunderstorm
        wind gust to 58 mph blew over several tents at the Cherry
        Creek Arts Festival.  The same storm caused the roof of a
        hardware store in Tamarac Square to collapse.  One employee
        received minor injuries when she was struck in the head by
        falling debris.  The combination of intense rain and wind
        downed trees and power lines.  Electrical power outages
        affected 35 thousand homes and businesses.  At least 50
        trees in city parks across south Denver were damaged.  Up
        to 4.50 inches of thunderstorm rain fell across portions of
        southeast metro Denver.  The underpass at I-25 and Parker
        Road was inundated with 5 feet of water.  Several other
        streets and underpasses in Aurora were also closed due to
        high water.  Heavy rain caused extensive damage to several
        exhibits at the Cherry Creek Arts Festival.  Flash flooding
        occurred when heavy thunderstorm rainfall caused Toll Gate
        Creek to jump its banks.  Several underpasses across south
        Denver had to be closed due to high water.  A man received
        minor injuries when lightning struck a nearby tree at the
        Wellshire Golf Course.  Hail as large as 1 1/4 inches in
        diameter fell in Englewood with 1 inch hail in the City of
        Denver...and 3/4 inch hail in Littleton.  Thunderstorm winds
        gusted to 63 mph at Denver International Airport and to 62
        mph in Englewood.
      In 2005...a tornado touched down briefly near Brighton...but
        caused no damage.
      In 2011...severe thunderstorms produced hail...up to 1 inch
        in diameter...and wind gusts to 60 mph across parts of
        Adams...Broomfield and Denver Counties.  At Denver
        International Airport...a peak wind gust to 59 mph from the
        west.
