Moved this here, and expanded on it fwiw.

I am also waiting to see if a wound-up system happens in Nov, which historically has been a great sign for our region in La Nina years. Here's a list for the Lwr. Lakes:

How do the great November storms correlate with La Nina ENSO?

Nov 1950 (Great Appalachian Storm): La Nina

Nov 1966 (985 mb): possibly neutral

Nov 1975 (Edmund Fitzgerald): La Nina

Nov 1998 (Fitzgerald storm 2.0): La Nina

Oct/Nov 2010 (Octo-bomb): La Nina

Nov 2013 (TOR outbreak but non-snowstorm): La Nina

4 out of 6 on that list featured a full-fledged blizzard the following winter!, and iirc the other 2 were pretty snowy winters as well, at least for certain parts of the Lakes. 

Edit- If you take into account the Nov '50 storm was itself a blizzard for a large portion hardest hit, you actually have a fabulous 5 of 6 years producing blizzards!

My local office's regional zoom-in and disco/forecast for our first year La Nina winter. I like it!

And IF the blocking ends up being a bit more dominant than they are calling for, this could certainly go bigger.

@Tom

So, is this an east-based Nina? And were certain outlets expecting more of a west-based that would/could explain WxBell's early call to bottle the cold more NW?

I don't believe they were anticipating a west-based La Nina.  And yes, this is certainly trending towards a moderate east-based La Nina.  In fact, the recent runs off the CFSv2 are categorically getting colder, esp during the heart of Winter right around the New Year.  Pretty wild stuff.

You can tell the modeling is on the right track based on the subsurface anomalies which showcase a divided PAC ocean and all the colder waters on the eastern side.

Alright, alright, alright...I promised to post the latest run off the IRI-Multi Model ensemble and like last month, for comparisons and trend purposes, I'll show the current run and compare it with the previous run.

 

NDJ...cooler and wetter trends across the heartland and OHV while the southern tier and SW/W coast remains warm and dry...

vs previous run...

DJF...same trends continue and notice the warmth over the Arctic regions and Greenland...this is why I believe some of the climate models are not potentially seeing the Greenland Block in the longer range...

Current run...colder across the OHV/MW that may suggest a snowier pattern???

What say the Euro Weeklies from yesterday???  After a very cold finish to October, the pattern relaxes a bit during the opening of November through about the 15th or so allowing "Indian Summer Part 3"...possibly???  It does appear that the west coast ridge will try to poke east into the central Plains during this period but there remains a lot of Blocking over eastern Canada/Greenland that may negate any significant (more normal temps) warming over the eastern Sub. 

Moving forward, for the 3rd run in a row, the model is continuing to show the pattern flip to what we are experiencing now and that is a west coast ridge along with blocking over the top from the 15th onward.  Almost a perfect scenario because it would allow all of us to finish up any yard work that needs to be attended to during the opening days of November and then nature can lay down the snow right around the beginning of the holiday season.  Check out this Snow mean forecast and you can clearly see the suppression of the cold that comes later in November.  Hope to see this trend continue.

Thats still no snow to Dec 1 for me and what would be a western trough to get that much snow. 

I think November brings snow as far south as I-40 before Thanksgiving in NE Oklahoma so I have to disregard that map.

Guess I'm in disagreement. The pattern is already set in stone, imo.

Here's a detailed write-up by Ben Noll that goes into a lot of details for this upcoming winter season.  He focuses on the northeastern U.S., specifically Hudson Valley, but you can use this as guidance for your local region as well. Some of the analogs he's using are catching my attn as I'm sure they will for you also.

Out-pacing just about every year in the pack at this point on the calendar, eh? (for N Amer). Too many lines of similar color to parse exact years like comparing 2013 for instance. Be nice if you could toggle certain years on/off for easy comparing.

https%3A%2F%2Fbucketeer-e05bbc84-baa3-43

Wisconsin State Climatology office has 13-14, as above average, and 07-08 as the snowiest winter of all time with 08-09 with the snowiest December on record. 10-11 is a good one too though it's more backloaded.

17-18, and 99-00 were both below average. Those analog years are a good sign but they aren't a promise. What was happening in 17-18 and 99-00 to make these the same and why was the snowfall output so much lower in the Midwest? Looking at these analogs, at face value it looks like we're far more likely to do well with snow than not.

I'm getting quite excited, I did some epoxy repairs to my board and went out on the lake yesterday in the wind. Suffice to say there was probably 2-3 foot chop out there and I was on a little stand up jet ski, I got my butt handed to me, haha. I'm about ready for some snow, only three to six weeks left for snowboarding. Really need a hard shot of cold early in November to get temps below 28 for a few days so they can open up.

The short answer is "there are duds in every ENSO state". 99-00 was bad across the board iirc. 17-18 was actually AN but for a different region (i.e. mby and eastward were AN).

I certainly agree that our "odds" based on his analog list look promising. It is ofc, just an educated hunch and nothing's been following the analog lists lately, so we just won't know until we know. It could dud, or equally, it could over-perform.

Thanks Tom. I really enjoyed his write-up and his style/approach. I like his set of analogs too for the most part. But wow at those snow maps off the Euro/Ukie, how disappointing that would be. Basically a 3rd straight winter of blah for the Lwr Lakes/OHV. Seriously hoping that those are not taking into account blocking that we've seen develop often so far. Thoughts?

Thanks Tom. I really enjoyed his write-up and his style/approach. I like his set of analogs too for the most part. But wow at those snow maps off the Euro/Ukie, how disappointing that would be. Basically a 3rd straight winter of blah for the Lwr Lakes/OHV. Seriously hoping that those are not taking into account blocking that we've seen develop often so far. Thoughts?

The scary thing about this is, both of these models have done well together in recent years, esp the Ukie which nailed the 500mb forecast last year and I think the year prior.  This year, however, I've seen how badly the models have done with the AO/NAO forecasts.  That's not to say they will bust again this year.  I just feel that how this pattern is setting up, while still early in the game, will pose a threat for high lat blocking in the winter months.  I'm sure there will be episodes where the blocking wanes when the PV strengthens or positions itself near Greenland.

For instance, the Euro op run below shows this transpiring later next week...this is when I believe we'll see exhibits of this LRC illustrate "cross polar flow".

I'm not an expert when it come to the MJO but I believe phases 8 and 1 are cold for the US which looks to be the direction it's heading.

Saw this tweet by Judah Cohen as he posted a chart comparing recent La Nina winters...

Quote

La Niña is thought to favor a mild #winter in the Eastern US but recent La Niñas feature many large #polarvortex disruptions which is often followed by severe winter weather not only in the Eastern US but elsewhere across the Hemisphere

I'm seeing signs that the QBO is heading out of the westerly phase and into the easterly phase by the end of the calendar year.  Could this aid in negating a chance of a warm winter?  I'm curious to see what the PV did back in 05/06 which is one of the analogs this season that ended up becoming a warm winter.  This season could be a lot different if the PV ends up being weaker.

Brett Anderson came out with his 2020/21 winter guess. While his guess is for Canada for those of us living in Michigan, Wisconsin, Minnesota and the Dakotas  there is enough of a over lap that his guess get into our area.  His guess is pointing towards a warm winter with less snow for much of our area.  Here is his summery for the winter season.
“Overall, in terms of temperatures, the core of the Arctic air is expected to hang out across northern BC and the Yukon Territory, though there certainly can be brief spells of bitterly cold air through the Prairies and into eastern Canada. However, the winter as a whole is expected to be dominated by more mild spells from the Great Lakes to Atlantic Canada.
The lack of sustained cold is expected to reduce the number of lake-effect snowfall events downwind of the Great Lakes this season. Ice cover on the Great Lakes is also expected to average below normal this season.”


Remember that is Brett Anderson’s guess and not mine.

I remember we had thunderstorms in the beginning and at the end of January 2006 and plenty of warm temps.

IIRC, the soils that winter around here never really froze hard enough and people could continue with dirt work like tiling, etc!

@Niko- Looks like a sliver of SEMI gets into the "worst of winter" zone. Hoping that zone is back west a bit too, lol

Now that makes much more sense, lol. Seriously tho, when's the last time you can remember the map I posted actually happening? Like, never. It crossed too many wx zones in all the wrong and non-typical ways to make sense. I think this new one actually welcomes Clinton into the "WOW" zone as well.

Here's a chart that will define the reason why I believe the models are right about the Scandinavian Block playing an important role this Winter.  Sadly, Siberian Ice extent is shattering record lows in 2020...open waters in this region during the winter will aid in high lat blocking.

LOL this NW flow won't allow this to happen for me.  Lots of time for a pattern change sill.

To me, the WoW zone is the region where S Stream systems criss-cross with the primary Clipper track. What he's showing would be the S Stream hit zone ala GHD-1 bliz and to some extent the PV bliz of 13-14. So for the WoW zone to extend that far SW to include W MO, those would have to out-number the clippers and I've never seen that kind of season tbh. I do 100% agree that the most likely region for big systems is just SE of where the arctic air masses come down. This should be fun if we can hold onto what's underway right now.

During the most crucial time of year, when the LRC is developing, the MJO is forecast to rotate through the colder phases of 7/8/1 as we close out October and head into November.  Question is, does it continue rotating through the warmer phases later in Nov or does it fall into the "null" phase???  What do we know so far???  We do know that there will be a SER influence this cold season as we've had a persistent -PNA pattern.  Is there a part of the LRC where the SER is not present??

 

The Euro Weeklies suggest November to have a general +PNA pattern...

Ensemble Mean PNA Outlooks

 

MJO Forecasts show the ensembles heading towards 7/8 and maybe phase 1...amplification, or rather, the influence doesn't seem to be that great.  There is also JMA support that we indeed head into phases 7/8/1 and 2 as we head into Nov.

The Euro Weeklies of late, have been advertising a steady trend for the second half of November.  The past several runs it has been showing a more winter-like pattern for a lot of the Sub.  What about the Thanksgiving holiday period??  Well, this 500mb pattern is a great way to start off the holidays.
