Love The Clouds Contest #53 - UFOs Anyone?!

This is my entry to @tobetada´s edition of Love The Clouds Contest #53. These clouds often appear in our town and because of our proximity to the Sierra Nevada range of mountains, they are formed because of the precipitations in the atmosphere..... these types are called lenticular clouds. Below is Wikipedia´s description:

Lenticular clouds (Latin: Lenticularis lentil-shaped, from lenticula lentil) are stationary clouds that form mostly in the troposphere, typically in perpendicular alignment to the wind direction. They are often comparable in appearance to a lens or saucer. Source
