Ties one other date for the earliest freeze on record going back nearly 150 years.
Denver’s temperature plunged from 93 degrees on Monday to 32 degrees on Tuesday. It’s a tie with September 8, 1962, for the earliest freeze on record going back nearly 150 years.
The National Weather Service has recorded six other days since 1872 where the temperature dropped by 60 degrees or more in Denver, but they were all during the winter.
