Since in BW the weather is the same /everywhere/ that wouldn't work, but 
AW has had parameters to dial that in the advanced options dialog for 
ages (I think it's called persistence or so).

There's two parameters - one dials how often the current cloud config 
will be changed, the other how often the system will switch to a 
different tile type.

If persistence is high, you'll get the same conditions over hundreds of 
kilometers, if low what you see will be different in every tile.

Sounds like what you're looking for, no?
