While in general I agree with the 'no bad weather' thing, I will hold onto my opinion that acid rain is the exception. Even soot-type weather is only inconvenient, acid rain is outright hostile. Hail is dangerous, much like lightning, but both can be beneficial.

I don't think I've ever heard nice things about acid rain beyond 'it wasn't as bad as it could have been' which is a depressing outlook honestly.
