The site this screenshot comes from, SpotWx, is actually really awesome for looking at weather forecasts in detail. (Most of their models are only for North America, sorry Europeans).

I actually am. :) In my experience the cloud cover models are usually decently accurate to a couple days in the future, especially when the predicted cloud cover is near the upper or lower extremes and all the models agree. It’s pretty uncommon for it to be completely wrong and get overcast conditions when a clear sky was predicted, or vice versa. (Though it does happen; I remember checking the predictions a day ahead and seeing clear skies, only for it to be overcast and raining the next day).
