And on Saturday if it goes as projected there is a very good chance that Dallas will surpass a 117 or even 120 heat index. 120 requires about 36% RH if the 106 is reached.
And that 106F would be coming with a relative humidity below 36%. Because relative humidity declines with temperature, as we've told you before.

No, the changes are ~20 degrees. We're talking about the average high to the average low.

That is of course a given. But how much it is below the average will have to be seen. In general the daily range of humidity in Dallas is not huge. So we shall see.

Virtually never. When very hot it tends to cool well at night. Often down 25-30 degrees from the high.

You've never been obviously.

I'll take a Las Vegas summer night over a Dallas summer night.

Is that due to the fact that hotter air can hold more water? So as the air heats up, the relative humidity goes down?

I've lived in both Dallas and Phoenix and I've felt that Dallas' summers are more tolerable.

Actually, it is, especially during spring and summer. Mornings can start out quite humid, but afternoons can dry out significantly. This is due to dry air mixing from either the dryline (during spring) or from subsidence aloft (summer).

You two are absolutely wrong. Check out the stats using the links below, and you'll see:
National Weather Service Climate
National Weather Service - NWS Phoenix
National Weather Service - NWS Las Vegas

The issue is that people don't understand that not all deserts are the same. The "cool off at night" thing applies only to high-altitude/high latitude deserts, whereas subtropical/tropical lowland deserts are a whole different ball game. You may cool off at night in places like Las Cruces or El Paso, but that ain't gonna work in Phoenix or Dubai.
