Other things we are seeing in these 8-10 day height anomalies are how there is a strong +PNA. This +PNA appears to be overwhelming the US weather. At the same time, the Alaskan Vortex looks to be shunted westward away from Alaska, where the +PNA ridge may be inclined to propagate towards Alaska. This remains to be seen but appears to be a valid possibility.
There is a -EPO spotted on the long range ECMWF but not really existent on the GFS.
