Talking about ECMWF forecast products
I don't think that any of the above mentioned parameters are available
(EXEPT soundings).
In the latest newsletter (No. 156, page 37)
https://community.windy.com/topic/6333/ecmwf-newsletter-summer-2018
is mentioned that soundings are available.
Hope some day windy will add these diagrams.
