@rene_ser, @Ondřej-Šutera, was this ever resolved. I'm seeing the same one-day error as well when I compare archived data to screenshots previously captured live from windy.com on a given day.
@bapo Hello, yes, the 10-day forecast outlook is now part of the Windy Premium subscription. The 6-day forecast is still available for all our users without Premium.

Yes that's right, the previous INFRA layer has disappeared. Only INFRA+, now called IR in the mobile app, is shown with the colorised low temperatures of high cloud tops.
What does the old infra red layer without color really was bringing?
@TZ
You are right, this is obvious when latitude-longitude grid is shown (see Settings).
The reflection of the sun moves a little more north each day and will disappear before reappearing around September 20 at the time of the equinox.
