Not only did the heat impact the daytime, it kept things quite warm in the night and morning setting two records for the date.
As measured at Denver International Airport, the Mile High City’s low temperature for August 21 was 72 degrees. This was easily warmer than the previous record high minimum for the date of 67 degrees set in 1946 and previous years.
