And the net result? High and low temperatures yesterday at the Salt Lake City airport of 91 and 70 (close to the averages of 93 and 65), some afternoon clouds, and a thunderstorm here or there. Ho hum. And the NWS forecast through the end of the work week? Fairly seasonal.
Really, this weather is just splendid. These are tolerable temperatures for July.
