...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 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
        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.
4-5   In 1875...nearly every railroad running into the city was
        damaged by heavy thunderstorm rains.  The heavy rains
        washed out wooden bridges over normally dry creeks.
        Some trains were entirely suspended.  In the city...heavy
        thunderstorm rain totaled 1.05 inches on the 4th...but
        only 0.28 inch on the 5th.
4-8   In 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.
5     In 1908...a late evening thunderstorm produced sustained north
        winds to 40 mph...hail...and 0.45 inch of precipitation.
      In 1949...a dust devil...possibly a small tornado...was observed
        3 miles to the northwest of Stapleton Airport.
      In 1973...the temperature reached 100 degrees at Stapleton
        International Airport.
      In 1974...strong thunderstorm winds damaged a mobile home...a
        barn...two houses...and several sheds near Watkins.
      In 1975...a thunderstorm wind gust to 53 mph was recorded at
        Stapleton International Airport.  Hail up to 3/4 inch in
        diameter fell over the northwest suburbs and in northwest
      In 1977 three houses in Denver were struck by lightning.
        Some heavy damage and fire occurred.
      In 1990...lightning caused minor damage to houses in Castle
        Rock...Louviers...and Littleton.
      In 1996...lightning caused only minor damage when it struck
        a home in Evergreen.  Lightning from a fast moving
        thunderstorm blasted a large hole in the side of a house
        in Lakewood.  Lightning triggered a minor power outage in
        the Boulder area.  About 200 homes were affected.
      In 2001...severe thunderstorm winds gusted to 60 mph at Denver
        International Airport and to 70 mph...7 miles southwest of
        the airport.
      In 2008...microburst winds downed a large tree and some power
        lines near a Denver apartment complex.  Several of the
        tenants` vehicles were damaged.
      In 2009...a wet microburst produced very strong winds in and
        just east of Denver.  A peak wind gust of 69 mph was
        measured 1.5 miles east of Denver.  In addition...1.50
        inches of rain fell in 30 minutes.  A peak wind gust to
        68 mph was also observed near Byers.  Southwest winds
        gusted to 31 mph at Denver International Airport.  The
        airport also recieved 0.30 inches of rainfall.
