Number of Forecasted Days
I was able to get ten days of Windyty forecast previous to upgrading to Windows 10. Now that I am on Windows 10, all of my browsers only allow me to see five days of Windyty forecast.
we switched the default model to ECMWF which has only 6 day forecast. If you choose GFS model from the option (just above the overlays), you will have 10 days forecast.
