Default Why no Scandinavian high influences?

Is there a reason why, despite the apparent change to colder winters in
the last three years, we rarely see any direct influence of the
Scandinavian HP, which in itself seems less inclined to form?

Yes!
In my opinion warmer arctic oceans decrease the Atlantic baroclinicity thus
reducing the opportunities for warm air to be thrown northwards as deep
depressions turn north which would aid anticyclonic development over
Scandinavia. Instead we have more opportunities for mid-Atlantic blocking as
depressions leaving the US eastern seaboard lose vigour turn and throw warm
air up east of Greenland. That is probably a gross over-simplification
though as I have not considered the northern hemispheric circulation with
that.
