Hi,
This has been requested several times before, as late as January of this year. I have been using Windy for years, but I do find the lack of inclusion of the Scandinavian forecasts as a huge drawback. There is a reason why HARMONIE-Arome have been adapted to our region. To quote Müller et al., 2017:
many aspects of weather forecasting in the Nordic region (Norway, Sweden, Finland, and Denmark) benefit from a better description of small-scale phenomena and forcing;
that is, the topography, coastline, and land-use contrasts may steer temperature, wind, and precipitation gradients.
In addition, severe weather, such as polar lows, is more likely to be simulated with kilometer-scale resolution, as a result of the improved representation of the smaller spatial scales of high-latitude dynamics (Kristiansen et al. 2011).
As noted by others, the latest MEPS data is publicly available here:

They also have a USER GUIDE HERE
More information about why an more specialised Arctic adaptation is necessary HERE
The latest AROME-Arctic data is publicly available here:

Any possibility of this being included in you model catalog?
