Clouds & Stealth Contrails

I am getting out of touch with which kind of cloud this was, but it made for a beautiful sunset.

These contrails caught my eye as I was beginning a hike. as it turns out they were three stealth B2 bombers on closer examination

These clouds are desperately trying to become mammatus clouds and made for a beautiful sunrise.

These clouds are trying their hardest to become the rare Kelvin-Helmoltz clouds.

These clouds are trying very hard to imitate lenticular clouds.
