ICON meteogram, is there a bug?
Look at this situation with overcast high level clouds and no medium and low clouds.
When in ECMWF (also in GFS), the clouds in meteogram seems to be OK.
.... when I try to make the same with ICON, no clouds in meteogram
although the high and medium cloud maps show overcast.
I can confirm it. It seems that high clouds are omitted in the ICON detailed forecast.
