Anyone managed Overcast weather in FMB?
 

(In objects/local weather, I select overcast or overcast with breaks and save them it, but they just shows up as patchy clouds.
Is there a secret way to get overcast weather?

I've been wondering where the overcast conditions are too. There is certainly a lot of lovely, clear days compared to 'real' Britain / France.

Maybe it's been disabled initially due to performance issues?
