Sorry for taking this thread off course but it is not fair to say that the Yahoo weather app is "GFS-fed". The forecast for the App is generated by us at the Weather Channel and in recent years it often uses more ECMWF than GFS as we have a choice as to which model to use. It is also edited by forecasters such as myself, although granted we don't always get it right.
We pay a considerable sum of money to the ECMWF for full access to their model data, just as Meteogroup do.
Thanks, John
