...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.
2     In 1938...heavy cloudbursts in the foothills near the top of
        Genesee Mountain caused flash flooding on Bear Creek at
        Morrison.  Nearly 8 inches of rain fell just north
        of Morrison in 6 hours and drowned 6 people in a car
        between Morrison and Kittredge.  Damage was estimated at
        nearly a half million dollars.  Flash flooding also
        occurred on South Boulder Creek in Eldorado Springs.
        Rainfall totaled 4.42 inches in Eldorado Springs...and
        rainfall was estimated to more than 6 inches in the
        foothills west of the town.  Many buildings and residences
        were damaged in Eldorado Springs...and bridges were swept
        away.  The high waters forced residents from their homes
        as far downstream as Erie.  This was the flood of record
        on South Boulder Creek.
      In 1973...hail to 3/4 inch diameter was reported in Boulder.
      In 1987...lightning struck two men who were standing under a
        tree in downtown Denver.  Both were seriously injured and
        hospitalized.
      In 1996...lightning sparked a brush fire in the south buffer
        zone of the Rocky Flats Environmental Test Facility.  No
        structures were damaged...but the fire burned about 100
        acres of grassland before being contained.
      In 2019...the record high temperature of 100 degrees was set
        in Denver...shattering the previous daily record of 95
        established in 1983.  Not only was the daily record set...
        it also set the all time monthly record for September.
        The previous record for the month was 98 degrees...which
        was set the previous day.  In addition...it was the latest
        100+ degree day ever reached during the calendar year in
        Denver`s climate record...breaking the previous mark by 17
        days.  The previous record occurred on August 16th...2002.
        Lastly...it was the hottest Labor Day on record.
2-3   In 1892...there was a trace of rainfall each day.  This...
        together with a trace of rain on both the 7th and 8th...was
        the only rainfall of the month...making the month the driest
        on record.  The monthly record was equaled in 1944.
