Two days in a row Denver has set or tied record low temperatures.
On Friday at 5:55am the temperature at Denver International Airport dropped to 26 degrees easily setting a new low temperature record for October 2nd. The previous record of 30 degrees was set in 1999 and also in 1959. This was the first freeze of the season. Thornton however remained above the freezing mark with a low of 33.1 degrees.
Following on yesterday’s record setting cold, the Mile High City tied a 109 year old low temperature record this morning. The temperature at Denver International Airport dipped to 31 degrees tying the record low for this date last set in 1900. Unlike yesterday, Thornton was actually cooler than the official Denver temperature having recorded a low of 28.2.
The average date of Denver’s first freeze is October 7th so we are a bit ahead on timing. The earliest date Denver has received freezing temperatures is September 8th which occurred in 1962. The latest date was in 1944 when the mercury didn’t dip to freezing until November 15th.
