Even if we never see a true +PNA, don’t you think the blocking up north can still get the job done? It’s been so long since we’ve seen that type of a -NAO with plenty of cold air available in Canada to work with

Snow in Florida with thatHa, that's what happens when the flow gets blocked....things start backing up and causing trouble, lol. GFS started out slow, but ended with a bang
18z GEFS pushing this to day 10-12 finally 
Been noticing time to time hints that ensembles like that PNW/pac cutoff - ridging in the C US and the block in place with backed up flow and energy stuck under the block, almost KU esque in some ways

18z GEFS not bad here...cold air fans out west to east out of western Canada under the block, then sags south to Cozumel
I like how the block migrates to Wisconsin. ?Ha, that's what happens when the flow gets blocked....things start backing up and causing trouble, lol. GFS started out slow, but ended with a bang
We need a few cutters to set the table and lay down the snowpack up here! A few clippers as well!12z Euro Ensemble member cluster analysis for days 11 to 15. Not a ton of difference though the weakest cluster on the far right has more ridging along the east coast and the top cluster on the far left is tucking low pressure underneath the block and rolling it through the Great Lakes at Day 11 and into the Northeast at Day 15 with a stronger low pressure. This would be an ideal progression as getting low pressure to strengthen and slow down as it moves into the Northeast and off the Northeast coast would set the stage for the next waves in the flow arriving from the west to slow down, head south, and deepen the eastern trough, a key component to driving colder air and the storm track farther south

The only thing I can say about December is that I don’t see how this disastrous “fall” could get any worse. November here has been so awful it would be a poor October.

Snow Cover Now At 56 Year High In The Northern Hemisphere - Just In Weather
November 28 2022 Does it even seem possible that our planet may have the most snow cover to date on modern record? We will be looking at the Northern Hemisphere as a whole and areas with any snow cover. So that epic Lake Effect Snow Storm last week was impressive, but only covers about 1% […]

Interesting article here. Could possibly have some implications going foward for us if we're able to get some of that blocking to push cold air our direction, we might be able to get some of it without too much modification. In other words, good snow buildup so far. ?
That Euro tho???
What is this showing?
Well that's fairly dazzling

You saw the same thing I did. It was about to go boom.Euro Control run shows the tantalizing possibilities
Verbatim, there’s too much low pressure over the northeast, so it would probably shear out by the time it got to the SE, but still a good configuration.

Man this was lining up for a serious snowstorm.
