Brown Dwarf Clouds

I have a little weird question about these elusive objects we call "brown dwarfs". It is ascertained that they retain various chemical species and molecules, from methane to water, but is it possible for large white water vapour clouds to form in a rather cold (<<1000 K) brown dwarf atmosphere? If it is, could these appear as white as in Earth's atmosphere or rather diaphanous? What would a late T-type brown dwarf's atmosphere look like?  

Eventual answers should take into account that I mean a brown dwarf orbiting a star (possibly Sun-like) and within its Habitable Zone, hence the question.
