It should be clear for all - longer term calculations is lower probability. Can you consider to show probability of accuracy for particular date and model selected?

For example - GFS is terribly bad accuracy for long term calculations, afaik 5 day calculations is less than 50% accuracy, in most cases, it provides nonsense results, at least at summer time in central Europe.

It colud be nice to know what is calculations accuracy, it's known isn't it? Can you also show that value on map?
