Emit, this can happen quite a lot. More a case of when an airfield has a high elevation. You're more 'in cloud' than in fog. Especially when the airfield is on a ridge. The uk had two notorious examples...answers on a post card.
Again, I keep it simple. Wind limits for the autoland are exactly that. They are in the limitations section of the FCOM. Therefor, if the wind is out of limits - don't perform autoland. Simples. When or where you make that decision is up to the commander.
