@willottevanger Hi, you mentioned cumuls clouds - we do not have forecast of cumulus clouds. In meteogram you can see two clouds predictions. First is the cloud base according to ECMWF parameter with the same name. Second is the grayscale visualisation in the bottom part of meteogram. It is based on relative humidity in various altitudes, so you can estimate clouds thickness and their vertical distribution. These clouds parameters consider only large scale convective clouds, not small cumuli.
Satellite images are not in certain altitude. They are images from 36.000 km.
WV sat. images show the real time structure of WV in the atmosphere. They're not forecast products.
Windytv depicts forecast fields of clouds, rain, wind, rel. hum etc
Also take a look at
try different runs and you'll see totaly different forecasts for next Sunday.
