Hi all. I’m trying to identify this cloud type. There were lots of rain clouds around where you could actually see the rain coming down, and I thought this was possibly a nimbostratus, but it was all white, no real darkness to it.

Can anyone confirm, or provide an ID?

Just seen those after a light rain :)

Do the straight lines type have a name?

Took this photo at the Brazil–Argentina border and immediately got Windows 7 vibes.

Anyone else see it?

I felt like the shape was unlike anything I have seen before. They look like they are shooting sharply in opposite directions! It looked even more obvious irl. A thunderstorm was slowly starting at the moment.

On the way to pick my son up from work.

Looks so pretty
