Well, I was doing research on clouds at work, so I've aquired a lot of knowledge
about them :) For example: my image shows a fair weather cumulus, formed on a
sunny day by moisture rising in a thermal.

Should be quite possible. The cloud's isosurface formula is partly based on
blobs, so I can move them around to acheive the desired form. Though a true
cumulo nimbus ("anvil" cloud) would probably take a lot of blobs, and a looong
time to render!
