Most of the time, my weather posts are going to be related to the weather on, you know, Earth. But once upon a time, I was going to be an astronomer and sometimes I still find myself looking checking out space stuff. Well, a while back I saw this, a lovely example of clouds on Mars. They don't last long, and they certainly don't yield precipitation, but it goes to show you that even someplace as dry as Mars, the forecast isn't always as simple as "Sunny and cold."
Incidently, in looking for the link to that video, I found something else. Someone is a smart ass.
