Through 6 AM, the overnight minimum at the Salt Lake City airport was 58˚F, with temperatures likely falling below that prior to sunrise. At my place, it was 55˚F when I awoke, with cool air pouring through the windows. Relief! Simply spectacular sleeping weather.
Yesterday's high at the airport reached only 89˚F. It was the first day we did not reach 90 or higher since July 22nd. That 38 day run is the 4th longest on record, tied with four other such periods. #1 is a 50-day run ending on September 5, 1967.
Yesterday's low was 63 and that marked the end of a run of 51 consecutive days with a minimum of 64˚F or higher at 51, the 2nd longest all time behind a 75-day run ending on August 8, 2013.
One brute-force measure of the demand for energy to cool buildings is cooling degree days. Through yesterday, this August sits at 566, ahead of 2013 with 554.
