> whereas windy and other sites are combining the data from many weather stations and running forecasting algorithms based on it There may be other sites that are doing this, but I don't think Windy creates any forecasts on its own. Instead, it provides a nice graphical interface to show forecasts that have been made by others. In my US location, they offer the choice of ECMWF 9km (European Centre for Medium-Range Forecasts), GFS 22km (Basic free model provided by NOAA), NAM 5km (Regional mesoscale model run by NCEP), ICON 13km (German DWD), and Meteoblue (Swiss from the University of Basel).
