You seem to want to pick a fight which would be a mistake 

i know what I specifically observe while you share what you feel your model dependency tells you to . 
it doesn’t work to tell someone they “see it wrong”!

You monitor air pressure in Mongolia? Cool.

The party that is confused is you

You are Not the spokesman Nor the self appointed corrector of others. The simple lact of  observation is that for many years that region in the winters has had considerably less strong, very cold high pressure in the winter.

i hope this  cures your confusion and your need to “correct” others observations.  

You're right. It is not as cold there in recent years. Siberian HP is generally weaker. Do you know why?

The “why” is far less important than the reality of observing that so far high pressure is more  prevalent  You are not the board teacher posing questions to your students

The why is definitely important, but this isn't the thread.

I am a teacher actually, so it is a habit I guess. This is a place for weather/climate related discussion. We can all learn from each other.  

Anyway, back to my model dependency.

Time to take a break and go touch grass Howard.  Maybe take a drive out to Garrett County to see some snow.

I think the original question is one of potential interest?  Perhaps there is a correlation between Siberian HP and Eastern Conus weather?  Remember that ABNA index that Webb pulled out of the depths the other day.

The correlation is via the Siberian HP influence on the SPV and the lower level reflection of that, which is the AO. I believe the generally accepted idea is a stronger Siberian HP tends to weaken the SPV and that is associated with a -AO, which allows colder air to move further southward into the midlatitudes.

GEPS was onboard with this before, but 12z is the first I’ve seen GEFS move strongly toward showing the western ridge move off the west coast, allowing the eastern trough axis to shift westward as well. And what happens almost immediately? The gulf opens up and precip starts flowing toward us. This is all after next weekend (7th and after), but I like to see it. Thanksgiving through the 7th or so looks northern stream dominant. After that, small shifts could open us up to more southern stream involvement.

But then does the SER try to build? (at work so stuck working instead of looking at models :( )

Not within the next 16 days at least according to the GEPS and GEFS. A little SER or WAR can be ok to keep the storm track close when we also have cold air established. But in this case, having the whole pattern move a bit west lets the Gulf open up potentially.

I did notice some agreement between the GEFS and EPS on southern stream energy coming out of the SW late in their runs. A small detail late in the run that probably isn't worth mentioning but hoping the idea gains some traction in the coming days.  Lets get the real life version of an epic overrunning event.

EPS seems to be doing the same thing but later by a couple days. We’ll see how it all evolves in time.

That was from the Plains Blizzard of 1949 I think. What a Storm it must have been.

There were 20 ft Drifts in part's of my area during the 93 Blizzard and the Great Appalachian Storm of 1950 but, generally in area's above 2500 feet.

Yeah, that's right. It's listed in the NOAA Archives.The 40's featured a big one as well.

Here's an excerpt from Archives of the '49 One's :

   The Blizzard of 1949 is considered one of the worst on record for the northern Plains. The first storm began January 2 and continued through January 5, with heavy snow, strong winds and cold temperatures. Subsequent storms through mid-February produced enormous snow drifts that paralyzed much of the region.
