This has turned out to be a powerful 'clairslide', which is a 'landslide' of very cold air, and acts like an independent entity.
It's big enough to actually split on the Great Lakes. At this time of year, no clairslide can cross those lakes, because they have too much heat energy. However, that heat is extracted and turned into lake-effect snow.
Because it has drained all the cold air for the time being, the rest of the world is free to be warm, and fully in the embrace of clange.
You can see that Europe is happy.
