And if that is the case it might be a late spring (temp wise)

Not sure if it’s been mentioned r not . But system early next week holds some severe wx. Potential for parts south... depending if a healthy warm sector can develop
It seems that warm winters tend to bring cold springs. At least from my memory. Also if this pattern (with southern storm track) was to persist into spring, it would provide a cold outcome (average wise); which I think you're alluding to.

I agree with you . He always finds a way to show some ensemble run to validate his cold screaming . What’s funny is what he showed wasnt the latest eps run . I wonder why ......

This will be my last response to this, as I don't wish to derail this thread any further. I read all of his words. But he still manged to insert a reference to an historic storm, and then he gave the qualifying statement. It seems to me to be a nice way to have it both ways. I freely admit I could be wrong.
Yeah if we had any assistance in the north Atlantic we might be able to block that up enough to be good for us but right now it's a texas,oklahoma, tn, ms, ark, ky look

He did post the last one, which was 0Z. he actually posted 12 Z yesterday and 0Z today and it came out early this morning. I only posted one of the two he showed.

Agreed that’s why I said western areas . Truth be told come verification time it will be good for TX ,OK , MO

Sadly, we want the high sitting over New England to funnel the cold into CAD region. 1022 mb also isn't that strong enough for wintertime Arctic high either.
No caa on the back of the initial system means no chance
True but it's 8-10 days out and has time for the hp's and lp's to move into more favorable/unfavorable places and time for things trend stronger/weaker.

Forgive me for not feeling more optimistic haha.
"GLAAM Trends Contributing To Forecast Pattern
Negative trends in the GLAAM contribute to the forecast pattern over the next 15 days. GLAAM refers to Globally Averaged Angular Momentum and is a measure of winds relative to Earth’s rotation. It has been in its positive phases since mid-January and is forecast to return to neutral early next week. After that, an increasingly negative signal evolves, and trends from the Euro EN are additionally more negative in the longer range since its projections from yesterday. The GLAAM can be categorized by the Global Wind Oscillation (GWO), which contains eight phases depending on positive or negative state and trend. The next 15 days sees the measure progressing through GWO phases 8, 1 and 2, and historical composites for those phases at the 500mb level are shown below. The evolution is associated with a buildup in ridging over the eastern Pacific this time of year; although, the ridge is most often focused south of Alaska and thus lacks a clear connection to more significant colder source regions. Still, a trough is often seen over the Mid-Continent, which is reflected in the models." from Maxar

So basically, the GOA ridge we all love

And the WAR we are seeing.
Indeed! And here's part 2 from the same release:
"Mid-Range Pattern Reflecting +TNH and +AO
In the story above, the trends in the GLAAM were discussed as contributing to the forecast pattern, particularly with the placement of a ridge over the eastern Pacific and a trough over the Mid-Continent. Those features are associated with a pattern of +TNH characteristics. Another contributor to the pattern is in the high latitudes, where strengthened winds reflect a +AO state. These winds help to lock Arctic air in the polar region and is a warm signal across the middle latitudes this time of year. In the 6-10 Day period, the pattern continues to direct Pacific flow into the U.S., thanks to continued troughing near Alaska (i.e. +EPO). A pattern including the +TNH, +AO and +EPO resembles the forecast in the 6-10 day period, as historically the combination supports variability from the West to Central (insignificant correlation to temperatures) and warmer air in the Eastern Half. The +EPO signal weakens in the 11-15 Day (still +TNH and +AO), which could increase colder opportunities in the North as the South stays warm." from Maxar
Euro looks different altogether at HR 216 compared to 00z.
This winter in a broken nutshell, look at that little bit of ridging that was on AK fade away as those lower heights take control and we get this look, that +AO gots to go 
Well meh still too weak with the cold air push
