Along with a few days of summer-like heat, nighttime temperatures stayed quite warm for this time of year as well. In fact, they were extraordinarily warm today.

As measured at Denver International Airport, the Mile High City’s low temperature today was only 55 degrees. This sets a new record warm minimum for the date, breaking the old record of 53 degrees set inn 1932.

Thornton stayed even warmer with a low of 59 degrees soon after sunrise.
