It’s been a while since a meteorology post and, while waiting for a bus in South Corvallis two days ago, I noticed the most spectacular cirrus clouds I’ve ever seen.

The UK Met Office notes that they form when a warm front is on its way. True, that. (NWS forecast discussion valid at 3:29 a.m., Pacific, June 26th).

You’ll see a contrail in this video from a jet heading north. Wish I’d known then that this can interact with cirrus clouds: I would have had the camera going again as the whole formation twisted and warped from turbulence after the plane passed.

But then the bus came, so there wouldn’t have been much time for it.
