      Is there an overall accuracy for the cloud coverage predictions with Windy? And if so, are there different quoted accuracies for how far into the future the forecast is? Say, the average accuracy for forecasts in 1-hour is 95% and the average accuracy for 14-days is ~30%. Thanks!

        No, it depends on the weather model you look at. Then it depends on the time stamp. For the next day it is quite accurate, after 5 days the accuracy drops down. And there is not a fixed probability for each model and each date. It varies with different weather factors.
        Referring to the ECMWF model, this article may give you more information

        Just as example
