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

29-2  In 1990...almost a year to date after the record breaking heat
        in early July 1989...the third longest heat wave in Denver
        history started.  From June 29th through July 2nd the
        temperature reached 100 degrees or more on four consecutive
        days.  The highest reading of 102 degrees occurred on the
        29th...30th...and 1st.  Combined with the 102 degree reading
        on June 27th this would have been the longest heat wave on
        record...but the temperature climbed to only 98 degrees on
        June 28th.
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.
30    In 1879...dense smoke from mountain forest fires covered the
        city and obscured the sun as it set behind the mountains.
      In 1900...a thunderstorm produced northwest winds to 44 mph
        with gusts to 58 mph...but only a trace of rain.
      In 1917...north winds were sustained to 47 mph with gusts to
        52 mph.
      In 1942...a strong thunderstorm produced hail and heavy rainfall
        in south Denver.  Leaves were stripped from trees and heavy
        rain caused street flooding which halted traffic.  Hail of
        unknown size reached a depth of 9 inches on the ground.
      In 1965...funnel clouds were observed to the south of Stapleton
        International Airport and in Jefferson County...15 miles
        southwest of the airport.  Later...a tornado touched down
        briefly 1 mile east of Littleton...causing only minor damage.
        Another tornado was observed 12 miles southwest of Stapleton
        International Airport in Jefferson County.  Hail to 3/4 inch
        in diameter fell in the Bear Valley area...12 miles south-
        southwest of Stapleton International Airport.  Yet another
        tornado was sighted 10 miles northwest of the airport.
        Cloudbursts accompanied by hail battered areas of Arapahoe
        and Adams counties east of Denver...damaging ripening grain
        fields.  At Lafayette...3.50 inches of rain fell in 30
        minutes...causing some flooding.
      In 1982...numerous funnel clouds were observed over southwest
        metro Denver.  Only one funnel touched down near the
        intersection of Jewell and Kipling.  The tornado was on the
        ground for about 5 minutes and caused no damage except for
        uprooting some trees.  In addition...thunderstorms produced
        heavy rain and hail in the foothills west of Denver.  Over
        an inch of rain fell in a short time near Idaho Springs...
        causing Clear Creek to overflow its banks and flood a few
        low lying areas of the town.  A few people were evacuated...
        and water and mud entered several stores.  The heavy rain
        also washed out several roads.  Hail piled up to a depth of
        3 to 4 inches near Idaho Springs.   Hail to 3/4 inch was
        reported at many places across metro Denver including
        Stapleton International Airport.  Lightning struck a
        chemistry building on the University of Colorado campus in
        Boulder and started a small fire.  Thunderstorm wind gusts
        to 60 mph were reported near Brighton.
      In 1984...heavy rain caused some street and basement flooding
        in Littleton.  One location received 1.56 inches of rain in
        75 minutes.
      In 1987...a weak tornado near Watkins stayed on the ground for
        5 minutes.
      In 1990...a small twister touched down in an open field just
        north of the Rocky Mountain Arsenal.  No damage was
        reported.
      In 1998...hail as large as 1 inch in diameter fell near
        Evergreen.
      In 2005...a severe thunderstorm produced hail as large as
        3/4 inch near Roggen.  The hail destroyed a wheat field.
      In 2006...the temperature reached a high of 98 degrees at
        Denver International Airport.  This marked the 19th day
        in June with a maximum temperature of 90 degrees or more
        setting a new all-time record for the month.
      In 2011...very strong thunderstorm winds were also observed
        across portions of the Urban Corridor. A peak wind gust to
        65 mph was recorded...2 miles northeast of Boulder with a
        gust to 63 mph at Front Range Airport at Watkins and
        7 miles southeast of Denver International Airport.  The
        peak wind gust measured at Denver International Airport
        itself was 45 mph.  A severe thunderstorm also produced
        one inch in diameter hail 2 miles south-southeast of
        Parker. In addition...a lightning strike destroyed a home
        in north Denver.
      In 2012...it was the hottest June in Denver since weather
        records began back in 1872. The average temperature for
        the month was 75.0 degrees which was 7.6 degrees above
        normal.  There were a total of seventeen 90 degree days in
        the month of June. The highlight of record setting month
        was a stretch of five consecutive 100 degree days from the
        22nd to the 26th. This was only the third time in Denver
        weather history in which this happened. Two of the high
        temperatures during the stretch peaked at 105 degrees...
        which set the all time record for the month of June and
        tied the all-time maximum temperature for Denver.
      In 2019...eight hikers were injured by a nearby lightning
        strike at the Devil Head Lookout...west of Perry Park in
        Douglas County. Five hikers were able to walk out
        unassisted...while two other required assistance. Most
        complained of having tingling sensations...while two suffered
        from minor burns. The eighth victim suffered critical
        injuries and had to be carried out by stretcher and taken to
        a nearby hospital.
      In 2023...a total of 5.35 inches of rain fell through the
        month of June...establishing the all time record for Denver.
        The previous record was 4.96 inches set 141 years earlier in
        1882.
30-1  In 1873...heavy rainfall overnight...from the 30th to the 1st...
        totaled 1.42 inches. Mountain peaks to the southwest of the
        city were covered with fresh snow on the morning of the 1st.
