Yes, we have gone to Easterlies twice so far . Two days ago, as psu stated, we were a a record negative for the date . Yesterday was close I believe by 1
Recovery questionable

The GEFS 35-day shows the point of uncertainty (abrupt spread growth) in the 10 hPa evolution around Jan 25-30. Some members continue to recover the vortex toward average, while others decelerate or even go for another U reversal. I think this is a point to keep eyes on!

This goes along with the above post regarding the GFS NH polar vortex ellipse profile animation .
Judah's animation matches the animation form stratobserve.com
Lastly, another huge change from what was forecasted the last 14 days . Movement towards Northern NA versus Siberia. This starts near hour 240 and speeding up from there.

Another significant change in the long range , a rather broad vortex in a N S elongated fashion is predicted versus what was forecasted a few days ago as a solidified , more organized tighter vortex, mostly over Eurasia.
As psu used this image in a previous post, but wanted to point out this is an improvement from a couple days ago.
Basically the - NAM states not deteriorating .

Recent EPS runs have trended stronger with Greenland blocking in the 5-10 day range again - now a 3 sigma event. There are also hints that a northern stream disturbance will be forced underneath it Days 7-10. If correct, would open door to a Mid Atlantic/Northeast winter storm.

And I stand firm that now you need a cooperative Pac to get a decent SECS in the Mid Atlantic. New England doesn't require that.
You want a more severe snow storm? Then you need some NAO help to raise the bar.
