Agree there pal, on the latest ensembles there has been a very strong +NAO making it difficult for anything to get a foothold in scandi. Can and will change as it's so far out but certainly not great chart viewing.
Who knows, the next runs might hint at the energy just off the eastern board digging south again, allowing ridging to set up as we want it too aka yesterday's 12z
Main point was, if we we did get a true scandi high emerging, I wouldn't be too bothered about the 850s before hand (build it and they will come) as the ridging will pull cold air down from the arctic into Scandinavia as part of the building blocks
All we can do is keep an eye out and hope
