I was able to capture, in time lapse, this interesting atmospheric condition.
It seems that a layer of cooler air had trapped moist, warm, air beneath it.
This is called an "inversion".
This was all happening at the base of a small mountain range with the cooler breeze racing overhead.
As the warm air gained enough momentum upwards, shown by the clouds boiling beneath, it eventually broke through the layer above to disperse clouds in the breeze.
A most interesting phenomenon, and one I hope you enjoy viewing.
