@dispatchdog said in Winds aloft and clear air turbulence:

Would it be possible to add the winds aloft forecast and clear air turbulence? Another thought would to have an overlay of aeronautical charts as an option.

Have you checked out XC skies? That site specializes in soaring forecasts, including winds aloft, updraft velocity, buoyancy to shear ratio, CAPE, etc. I use it a lot and love it.
Downsides: obviously, it may or may not be what you're looking for; doesn't help you if you really wanted all that in Windy; subscription needed to use all available forecast features (though you can check it out for a month or so for free).
