Realistic Clouds?

[Redroach]

I, for my part, was pretty satisfied when I went from the RAF campaing (total lack of any overcast afair) to the first axis mission. The clouds there looked reasonably good, even in the game's current alpha state; cockpit icing looks good, too and the "thunderstorm" effects were quite convincing when flying right through it.

I've yet to encounter actual rain, darkened sky and so on, however.
