I would also like to see this incorporated if possible as it has piqued my interest in weather forecasting! And yes, Google does claim it to be the most accurate in the world for 5-10 days. That combined with their 24-hour models represent the best forecasting in the world.
Granted, every media organization cites 5 studies proclaiming their own forecasting as the most accurate. So maybe it should all be taken with a grain of salt.
