That's a great photo sequence. The cloud is a lenticular cloud, the are not often to see. When stable moist air flows over a large eddie like those caused by a mountain, a series of standing waves form on the leeward side of the mountain. If the temperature at the crest of the wave drops below the dew point moisture condensation may form a lenticular cloud.
