Which model is most accurate for Europe?
However NEMS is much more accurate in mountainous region, in particular for temperature forecast, where other models fail.
You can do your own observation: Select « Reported temp. » or « Reported wind » and choose a weather station close to your location. Then you can compare which model show the closest values.
I know comparison of ECMWF model with few models including GFS in north extra tropical hemisphere, but not with ICON nor NEMS.
ECMWF is better in forecasting rain and wind (but overestimates wind gusts).
ICON (because of better resolution) forecasts better the temperature, low cloud cover and wind gusts.
For further reading:
Looking at the temperature forecast for now at my location (Prague), the observed temperature is 20 °C, EMCWF shows 26 °C, the other models 23 °C.
And looking at the peak Snežka (1602 m), EMCWF shows 20 °C, observed temperature is 10 °C. GFS shows 23 °C (lol).
Weather.com is almost spot on for both locations, I wonder what model they use.
@fh Weather.com uses a combination of weather models that make it more accurate. Which is the ideal way to forecast weather. The more models you have to compare, the more accurate the forecast will be.
It would make sense because in one cell of a 9 km grid, the elevation and therefore ground temperature can vary wildly.
BTW, I found that Weather Underground (owned by owners of weather.com) use their own model for US locations with hourly updates: https://www.wunderground.com/about/data. Dark Sky also use custom model: https://status.darksky.net/2017/06/14/hourly-updates.html.

@theradarguy The German Meteorological Office (Deutscher Wetterdienst - DWD) offers such statistically optimized point forecasts for about 5400 locations around the world as open data called MOSMIX. (Forecasting time step and update interval is one hour and the maximum forecasting time is 240h - https://www.dwd.de/EN/ourservices/met_application_mosmix/met_application_mosmix.html) The ICON model and ECMWF model are used as input.
Any idea how windy could visualize these point forecasts?
Maybe it could be added as additional model to the city weather details?
windy have available altitude data for any location.
Also model's surface height for any grid point.
The method described here:

@gkikas-lgpz Thank you for the information. These spot forecasts / city details seem to be the perfect place to also include MOSMIX. MOSMIX does not only adjust for altitude but takes into account a bunch of other statistical corrections and combines ICON and ECMWF, i.e., statistically the best of both worlds.
