Could you add charts for high temp ensemble / trend forecast like in the following examples (the shaded area shows the uncertainty of the ensemble forecasts):

The long range radar (lower resolution) should not be used instead of the short range radar (higher resolution) but additional to it in the areas not covered by the short range one!

@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.

@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?

@tomber42
Yeah, you are totally right. Ideally, it should be done by all the weather services. Now I wrote to DWD and asked whether the numerical prediction models for radar shift trends themselves are also freely available. Maybe we, windy, or some university can compute the trends for other countries by ourselves then.

Re: Which model used for currents/ waves and what resolution?
The German Weather Service / Deutscher Wetterdienst (DWD) offers free wave models on global, European und German scale:

Maybe this can be added as another model option?

@emsdude54
In fact the German weather service / Deutscher Wetterdienst (DWD) offers exactly this as open data (called "radar shift trend" internally): Together with the radar data for past hours, it includes a numerical prediction for the next two hours in 5 minutes steps on a 1km x 1km grid based on the past radar data. It would be great if windy could include this ultra-short-term prediction based on radar data, too!

@gkikas-lgpz
Well, you are right, but I was thinking of a free radar composite, which can directly be used for windy. I edited my comment and included "free".

Yeah, it's really beautiful! It's a shame that there is no official, free, comprehensive radar composite by the EU (at least for all the countries that offer free radar data). You are doing amazing work! 👍

A first step could be to show the ensemble results of one model as uncertainty area. See the following example (of the DWD WarnWetter app) for the temperature:
