On an average day — the vast majority of days, actually — air temperature gets cooler as you go higher in the atmosphere. Put very simply, the ground is warm and the sky is not.
That's why clouds form in the sky. If moist air rises up from ground-level, it cools in the sky and the moisture condenses into clouds, much like the condensation on a cold glass of lemonade during a hot summer afternoon. Water vapour in the air condenses on the glass.
In rare circumstances, the opposite happens — cold air is at the ground and warm air is above it. The atmosphere flips over and all of a sudden the clouds are at your feet.

The Electric Universe model is clearly explained, with a lot more relevant information, in the book Earth Changes and the Human Cosmic Connection by Pierre Lescaudron and Laura Knight-Jadczyk.
