We can have our clipper and eat it, too

 Hard to come up with new titles.  The big A8 Arctic Spill has cut out the first clipper, but more air is coming over the mountains.

Unfortunately, this won't form a standard clipper because a new monster is tromping its way down.

You can just see it up there.  The Alaska flow has been cut off, and we're the only flow in town.

A new Accumulation Vortex has started in the Arctic, so eventually we might get a break.  But the new spill is backed by some serious flow.  Any flow to Europe is mucked.

The regular forecast has stopped with the stop-flow, and shows coming down in full glory.  Since they define 'polar vortex' as cold, they can say that the cold is caused by the polar vortex.  No physics required.  And the jet stream will always sag with the cold, because it is defined as the boundary between the cold and warmth.  They have a great job!
