This output data shows cloud cover in percentages. Cloud patterns are very difficult to predict. The calculations also include forecasts for high cloud cover. 100% cloud cover signifies an overcast sky. If, however, the sky is overcast with cloud cover that is thin and the sun is shining through, it is still considered overcast, even though it may seem like a sunny day at first glance.
