Everytime I fly into LAS in the summer, whether it's windy or not, the approach is always very turbulent from about 14,000 to 2,000. Of course, the flight level varies. Typically, it begins as you break out of the clouds.
It's always a series of quick violent bumps, and seems to have little to do with the wind, although it is worse when it's windy. The turbulence stops as you level on final approach.
Is this the hot air/cooler air colliding?
I'm going to LAS in a few weeks, and have been meaning to ask this question for some time.

I flew out of LAS a couple years ago and the pilot predicted some choppy air. He referred to them as "thermals." As PhilB said, the turbulence is caused by the hot rising air. Since it rises unevenly, there isn't consistent support for the wings. Thus, turbulence.
