I've seen lenticular clouds before, but never, ever like this. When I left work today (Friday), I couldn't take my eyes off this scene, which was constantly in my line of sight all the way from Tacoma to Bonney Lake. I called Brian and asked him to get my camera and zoom lens ready for me. I whipped into the driveway, flew into the house to grab the camera, and took off to find a good vantage point. I was darting in and out of streets till I finally found an unobstructed view with no wires and no houses.
They are called "lenticular" because they are shaped like a lens. The appearance of them means a change in the weather, and rain is moving in tomorrow. Don't be alarmed, the size of them does not determine the strength of a storm. lol If it was, based on these clouds, we'd be battening down the hatches!! They form near very large mountains, like our Cascade volcanos, Mt. Fuji, etc. I'd never seen or heard of them till we moved here. We've seen much smaller ones, sometimes those sit right on the mountain top like a hat.
