Here in the Inter Mountain west , we rarely have days that are "HHH" or Hazy, Hot and Humid like the Eastern U.S. While that is a common expression in the Eastern U.S., there is a new phrase that I have drummed up to describe when our temperatures get very cool at night despite the hot days: CCC: Clear, calm and cool.

These CCC nights happen especially when the wind is light, allowing for what is known as radiational cooling. Ironically rural and suburban areas in the valley , more than the benches, get coldest. As an example, on a drive through Sandy last week, I was able to register a 15 degree difference between early morning temps at 4350' compared to about 4800' not far away, the LOWER elevation in this case was coldest.

In the wintertime, that "inversion" gets us in trouble with pollution, but at this time of year, of course, it burns off by day.

There you have it, the Triple C, and Radiational Cooling, they go hand in hand!
