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

1-5   In 1995...record breaking heat occurred on the first 5 days
        of the month when the temperature climbed into the 90`s
        on each day.  Record high temperatures of 97 degrees on
        both the 1st and 4th equaled the all-time record maximum
        for the month.  High temperature of 95 degrees on the 3rd
        was a record for the date.  High temperatures of 94 degrees
        on both the 2nd and the 5th were not records.  The low
        temperature of 64 degrees on the 4th equaled the record
        high minimum for the date.
1-7   In 1978...the temperature reached 90 degrees or more on seven
        consecutive days with the highest temperature...94 degrees...
        recorded on both the 4th and 6th.
1-30  In 2020...a worsening drought that started in the spring and
        continued through September. Outside of an early season
        snow on the 8th...the month of September was another
        unseasonably warm and dry period. The combination
        of hot...mostly dry conditions...and critically dry fuels...
        resulted in a continuation and rapid expansion of several
        massive wildfires. The Cameron Peak fire...which became the
        largest in the state`s history started on August 13th...and
        continued through September. As a result...very poor air
        quality continued to impact Denver and the entire Front
        Range.  Denver recorded the most days ever with a high
        temperature of 90 degrees or better; 75 days.  The last
        of which was 91 degrees on the 24th.  The previous
        record was 73 days set in 2012.
3-6   In 1909...rainfall for the 4 days accumulated to 3.97 inches
        in Boulder...while in Denver rainfall totaled 2.45 inches
        on the 4th...5th...and 6th.
4     In 1909...apparent post-frontal heavy rainfall totaled 1.94
        inches in downtown Denver.  North winds were sustained
        to 19 mph.
      In 1944...a trace of rain fell.  This together with a trace
        of rain on the 9th...10th...and 30th was the only
        precipitation for the month.  The total of a trace of
        precipitation for the month equaled the driest September
        on record first set in 1892.
      In 1960...the highest recorded temperature in September...97
        degrees...occurred.  The same temperature also occurred on
        September 5...1899...September 1...1995...and September 4...
        1995.
      In 1989...a strong thunderstorm wind gust flipped a plane
        taxiing on a private runway in Adams County east of Denver.
        Two people were slightly injured and the plane was heavily
        damaged.
      In 1992...strong winds developed across metro Denver behind a
        Pacific cold front.  Sustained winds above 40 mph with gusts
        as high as 60 mph were recorded mainly in and near the
        foothills.  Pre-frontal south winds gusted to 37 mph at
        Stapleton International Airport.
      In 1995...two people were injured when lightning struck their
        home in Lakewood.  The lightning entered the attic where it
        started a small fire.  It then traveled through the walls...
        exploding a mirror and spraying glass on the residents.
        Lightning also sparked small grass fires near Aurora...Denver
        International Airport...and Bennett.  The highest recorded
        temperature in September...97 degrees...occurred.  The same
        temperature also occurred on September 5...1899...September
        4...1960...and September 1...1995.
      In 2000...thunderstorm winds gusted to 64 mph in Castle Rock.
