You want complete overcast. There's not a lot to reflect as it's so soft, but that's when you start bringing in your extra lights (if necessary). Maybe a pocket par?
You don't want one of those peeking through the clouds days where every 5 minutes the sun has changed from a soft source to a hard source or vice versa.
