Hi @dchouinard, METAR is predominantly used by aircraft pilots and it shows info about airports. Data are provided by airports.
If you want to see weather forecast for this location, you can just check Meteograms :)
Hello @fsiljelof right now we are focusing on global weather models. Right we have models AROME and ICON which are more regional. We don't allow uploading your own data at the moment but thank you for your suggestion!
Implementing audio should be of course doable technically, while it would be pretty boring in practice (e.g. for i18n reasons).
At least on PC, left/right keyboard keys allows you blindly navigating within the time bar range (one key press for one time step), while keeping your attention focused on the area of interest on the map; the latest can be also moved (zoom in/out, drag&drop), in order to get it just above/near the time bar.
