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. 2-3 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. 3 In 1901...a thunderstorm produced rain...hail of unknown size... and south winds sustained to 40 mph with gusts to 43 mph. In 1961...the Labor Day weekend snow storm is the earliest date of the first snow...trace and measurable...of the season. The heavy wet snow broke many limbs from trees that were still in full foliage. The storm produced 4.2 inches of snowfall at Stapleton Airport with nearly a foot of snow in western suburbs and in the foothills. Minimum temperature of 33 degrees was a record for the date and the coldest ever recorded so early in the season. In 1999...severe thunderstorms dumped large hail across metro Denver. Hail as large as 1 inch in diameter was measured near Cherry Creek in Aurora and near Bennett. Hail to 3/4 inch in diameter fell in the City of Denver. In 2002...a thunderstorm produced a wind gust to 51 mph at Denver International Airport. In 2003...very heavy thunderstorm rain washed out parts of the Virginia Canyon Road above Idaho Springs. Up to 4 feet of mud reportedly washed down the road during the storm. Several vehicles were trapped on the road. In Idaho Springs...several streets...including the main street... were also buried in mud and gravel. Some buildings in town experienced minor flooding...including the basement of the town library and the police station. 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. $$
