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 days was established in the summer of 2008. 2 In 1879...a severe hail storm produced considerable damage in the vicinity of Arvada. Some of the stones were unusually large...measuring 6.5 inches in circumference (2 inches in diameter) with an average weight of 1 ounce. The stones were uniformly large with one side concave. The greatest damage was to early wheat...cabbage...and vines. A tree just to the south of the weather station in downtown Denver was struck by lightning. Residents in the house 15 feet away were affected by the strike. In 1885...thunderstorm winds were sustained to 50 mph in the city. In 1892...an apparent cold front produced sustained northeast winds to 40 mph with gusts to 45 mph. In 1955...a apparent microburst wind gust to 69 mph was recorded at Stapleton Airport where the brief strong wind reduced the visibility to zero in blowing dust. In 1965...hail...up to 2 inches in diameter...struck southwest Adams and northeast Denver counties...damaging cars...windows... and foliage. Hail accumulated up to a foot deep. Wind gusts to 48 mph and hail to 1 inch in diameter fell at Stapleton International Airport where the large hail broke three storm windows and shredded shrubs at the U.S. Weather Bureau upper air building. In 1968...a pilot reported a tornado 10 miles southeast of Parker. In 1971...one inch diameter hail stones were reported in Adams County about 30 miles east of Denver.

The twister occurred in open country and did only minor damage to a metal shed...porch...and mailbox. A man was killed by lightning in southwest Aurora. He was in his backyard and had a shovel in his hand at the time of the strike. A group of soccer players were hit by lightning on a field in Boulder.
