I've been tackling on the idea of starting this thread without linking the Winter months and focusing moreso on the Autumn period.  For now, this thread will primarily be geared towards the months of Sep-Nov and leaving out the "Winter Discussion" and/or Outlook at this point in time.  In the months ahead, we may just include them at a later point in time for the sake of compartmentalization.

 

With that being said, there is much to discuss as there are conflicting signals being forecast among the models in terms of the ENSO (which plays a big role in long range forecasting).  I'll just dive right in...

 

For instance, the CFSv2 just about a couple months ago was suggesting a La Nada to develop by late Summer into Autumn.  However, that in turn trended towards a weak/mod over the last month or more of runs. But wait, up until the last week, it's back to a La Nada!  What may be causing this erratic behavior???

 

 

Here is the most recent image of the subsurface SST anomalies across the equatorial PAC which have cooled back off significantly again.  I'm trying to search for reasoning but I'll be honest, I don't have one at the moment.  We'll just have to see how this blob of cooler waters interacts with the warm pool on top.  Will it erode it???  Time will tell.

You know Tom, as Texas reaches its zenith in terms of summer, our week of the Fourth will see temps in the high 80's - low 90's. We also are cloudy and have scattered showers and 7 counties under flash flood warnings. I think we will see an early Fall. Perhaps not as early as the GL area but early for us. My bet is September will be the turn and it will be cooler and rainier than normal.

Next week will be more normal, but this is out of character. Mid to high 90's down here.

Tom, I've been pondering the autumn about every day now a little bit. I've got a pretty firm mindset to think that there's not going to be anything on the southern end this year after about August 15th to stop cold. I've ran every possible scenario out that I can run off the top of my head and the only really bad one that could happen somehow is a thing like 1999. You have a mirror of a summer to this one, shut down growing early and then bake the central US under +4 to +6 all winter. It was one of the worst head fakes I can remember. 2000-01 was the mirror opposite sequence.

We'll have a lot to discuss this year.

This VERY rapid decrease in ENSO with the last few weeks all but eliminates the threat of tropical ridging being too strong or the Pacific overwhelming the nation.

Your statement right there brings up a good point.  I totally missed that and it would make sense to see less ridging across the central CONUS for the month of Sept.  Gosh, what I'm seeing in Sept are some good signals for strong troughs swinging through the central CONUS.  I'm telling ya, I envision some places across the north seeing their first flakes of the season and may break some records when talking "last flake" vs "1st flake".  The shortest summer transition in decades???  There are a lot of variables I'm paying attention to that are coming together.

IMO, the CFSv2 has done a very good job in recent years predicting cold air across the Arctic regions in the Autumn months.  It isn't a surprise to me that we are seeing another forthcoming Autumn with cold air being predicted up across this part of the world and an early build up of snow/ice is likely again.  In fact, I'm going out on a limb here and predicting one of the fastest snow cover build ups across North America during the month of Sept/Oct, which will only enhance our chances of early season snow/cold outbreaks.

 

 

I have long spoken about a climatic shift which is likely occurring across the Archipelago/Arctic regions of N Canada.  During this Autumn, I predict to see our own "home grown" Arctic Air to build up across Canada.  Remember when snow/ice was supposed to be a thing of the "past"???  Nature will yet again show who's boss.  Something big is going to brew up this year.  I sense it.  I believe it.  I see it.

I just read a very interesting stat and one that should raise eyebrows going forward...we will undoubtedly add to that as we progress for the remainder of this year. #lowsolar

Today marks the 68th day of negative North Atlantic Oscillation period. Among with 2011, this is the longest -NAO stretch on record (thread below).


Are we heading towards unprecedented times????

If we do a 2012-13 or a 11-12, I'm going to lose it. I might not ever talk about weather ever again. I'm semi-serious. :lol:

2012... When I think of 2012, I think of a 33.0° rainy Christmas morning. It was supposed to be amazing like 2009. 2012......no, just please no.

I'll quit whining but I hate that year. These probably belong in the complaint thread. :lol:

Ps. 2012 sucks.

No chance we see a repeat scenario of those years in terms of the Winter. The SST’s in the PAC are largely quite different and in some spots the opposite. Your going to do well this coming cold season.

This was the redeeming quality of 2012-13 and it happened right when we though winter had been gone. May 2-4, 2013 was pretty much a May miracle by weather standards here. It was also what served as a "check" or slap in the face that year to look forward. The following was the blitz from start to finish, the winter of 2013-14. That was just a fast-paced, ice-snow-thaw, repeat once a week year. Over and over.

@ OkWx, here is a comparison of the SST's for both of the year's 2011 & 2012 and you will quickly notice how opposite they are when comparing to the current SST pattern the models are forecasting for October.  Things can change, but I don't expect to see abrupt changes.  The only question I have for now is if there will be an El Nino or is the CFSv2 "seeing" a La Nada???

 

2011...clearly, you have a much different scenario across the N PAC.  The warm blob which is being forecast for the Autumn is replaced by a very cold pocket near Alaska which kept the GOA Low locked the entire cold season.  Warm blob NW of Hawaii compared to a cold pocket that's being forecast this year.  This is literally an exact opposite scenario and you have a La Nina on going.

2012...practically the same thing is happening across the N PAC except for a warmer equatorial PAC.

In terms of sensible weather here over eastern Oklahoma and looking at the temp gradients there, they were basically 2 low solar, cold ocean era Niños if contrast is worth anything.

Worst PAC alignment in the satellite era IMO. It was like the global circulation became stuck everywhere but the equator.

I did some reading last night on TSI and dug into some climatologists. I find it interesting that those that were scorned 10 years ago are being vindicated.

The consensus being that we are looking at a century of cold. The sun has a life of its own and we have to live with it. Many of these scientists see temps declining and the time period between 2030 and 2100 will see very cold times. We are in the early years of the cycle. This will be the 2nd fall and winter of the sun beginning to unwind this cooler sun.
We will see more solar maximums but overall we are living with a colder sun. Our job is to adapt.

That said Texas should see a wet cold fall and winter. Much like last fall and winter. I don't know about you, but I'm getting the message.

I sure hope we aren’t heading for very cold times, or I just might have to move to Texas!!

It's not so bad here. You can work on your tan!

Articles have spoken of 31 of the 32 models being tweeted to reveal what the US govt wants it to say, and that the Russian model is more realistic. I've come to not throw all my faith in the govts assessment as it's been shown to be wrong.
So, I do believe we will see colder years ahead. I just hope the severity isn't too bad. I like eating and farmers like to farm.

Consensus amongst scientists? We are not getting colder. Even with Sun lower maximum. It’s just not happening. Weather isn’t Climate.

Alright, now this has me a bit intrigued.  I don't know about you but this has got me thinking about next Autumn quite a bit.  Good bye Nino???  Was the JAMSTEC right all along months ago suggesting a La Nada or weak Nina by this Autumn???  The most recent CFSv2 trends are certainly veering far away from the weak/mod Nino it has been showing for a number of weeks now.  The more I think about this and the developing large subsurface cold pool across the equatorial PAC has got me leaning towards a La Nada or ENSO neutral conditions for the Autumn.

 

 

Those boiling waters up near the Bearing Sea scream SER for next year's LRC cycle.  Let's see if I'm right about that.

glbSSTSeaInd3.gif

 

usPrecSeaInd3.gif

 

What is really abnormal about how much the SST's are cooling across the central/eastern PAC over the last number of weeks is that we have a -SOI.  This alone suggests Nino conditions should be favorable.  The most recent JMA weeklies certainly paint a picture that downward motion will be prevalent across the central PAC over the next 4 weeks but the ocean SST's don't seem to be responding that way.  That's quite interesting.  Nature throwing a curve ball???  Time will tell how this all plays out.

This week, there will be several climate models coming out with their updated seasonal forecasts and some of them are the more pronounced ones which include: ECMWF, JAMSTEC, JMA and also the NMME.

So, I'm hearing that the Euro Seasonal did in fact trend towards the CFSv2 and no longer has a Nino.  Interesting, and something to ponder on as we get closer towards Autumn.  If that holds, I could see a one of the Autumn months being very warm, perhaps a true Indian Summer???  We've seen similar SST patterns set up both in '13-'14 and '14-'15....here were those Autumn temps.

Ive been reading a good deal from climatologists. Yes they disagree but US models have come under scrutiny for being scewed lately. I still think the overall trend is cooler. We will have warm Autumns and hot as hell summers but generally winters will be hard.

Yes, I do know that weather is not climate.

The latest T-depth anomalies across the equatorial PAC certainly paint the picture that the demise of the Nino is en route...gives me credence that we are definitely going to have a different pattern next Autumn.  Meanwhile, on a side note, this jives with my long term ideas that when we combine low solar activity, stochastic events globally,  and a potentially weak Nina that may have legs for 1-2 years...Global Temps should trend lower by 2021-22.

My long term thoughts are for a neutral-to-cool era for the next 12-18 months.

Seeing the PAC disconnect from the equator, in a sense, is kinda wild.

Seasonal are all going to go sketchy in the next month or so I'd imagine.

If I had to throw a warm month in autumn over the heartland, it would maybe be October. Maybe late Sept and 2-3 weeks of Oct.

Big change from the latest NMME ENSO 3.4 forecast from last month as it is now suggesting ENSO neutral conditions to progress through late Summer into the Autumn.  Something the JAMSTEC model was showing for months except for last months run.  I'd imagine the JAMSTEC will go back to what it was showing in previous months.  It certainly is looking likely that we will be experiencing a much different equatorial PAC environment for the 2nd half of this calendar year.

Here is the NMME's global SST configuration...there are several things that stand out to me which will influence the development of next year's LRC cycle.

 

1) Warm Ring in the N PAC

2) Cold waters in the central/eastern PAC 

3) Very warm waters along both U.S. coasts

4) Cold waters around Australia

 

With several of the above points mentioned, I would not be surprised at all that we see another year of an active SER and Split Flow pattern.

2012 really sucked in a lot of places! There was widespread severe drought that year & I think it was the hottest year on record in Iowa & probably many areas!

According to stats during a very questionable era of truth, supposedly the hottest ever globally. Either way, I know it was 2nd hottest here to 1936. Too hot.

This is the best "west-shifted" positive PDO and warm pool combo I have ever seen. If you want a precursor to a cold era, you're not going to find a better example. Incredible. That NP warm pool is epic. Pumping a huge portion of global heat right out of the mid-latitudes. Perfection. I've been waiting to see this literally for years and years. I've read about it and had to use my imagination, but it doesn't get prettier than this.

I was thinking the same thing not long ago.  The oceans are setting up to something I have always wanted to see happen.  Hopefully next cold season is the one that includes all of us in the fun and games.

Here is the most recent Euro seasonal anomaly plume for ENSO 3.4 region....

Meantime, the JAMSTEC came in overnight and it pretty much agrees with the Euro that a La Nada is in the works???

Thinking about winter at the zenith of summer (and vice-versa often), I'm thinking it's been too long since Marshall took a solid hit (8+) from a single storm.

 

The last 8+ event that was a solid Watch-to-Warned event was the 9.1" of Dec. 11/12, 2016!  Which will be 3 full yrs this December.

You have some making up to do buddy!  Let this be your year....La Nada's and weak Nina's are typically good for the GL's region.

I'm on "What is snow?" I hear about it sometimes. Lol. Is it something you eat? What does it do?

I've learned from past experience to carefully watch the trends in SST patterns across the N PAC and Equatorial PAC during the month of Sept as we enter the Autumn season.  It is my own personal opinion, as I believe we are certainly entering a climatic shift and one that resembles historical periods of the past.  The big "flip" in the modeling of a potential neutral ENSO event or La Nada for the Autumn gives me credence that the idea not only the Arctic will rapidly cool off this Autumn/Winter, but moreso, we will see a favorable hemispheric North American Vortex take shape in both Oct/Nov.  The maps below will verify my thoughts that I had earlier in the Summer.

 

As mentioned in the Summer thread, the JMA seasonal has come out and as many of you know, the all important month of October is now in our sights.  With that being said, I'm beginning to have more confidence that by Sept our continent will cool off significantly and lay down the groundwork up north by building a snow pack early and often.  If you look at the 500mb pattern, the alignment of the SST pattern in the N PAC should justify a wavy jet pattern in the early Autumn months (will likely start seeing that in August actually) and continue into October as the new LRC pattern sets up causing a dynamic Split Flow pattern.

I wanted to comment on the JMA's SST forecast for the month of October as one will quickly capture some striking similarities to the possibility of some cold Autumn months in recent years.  Firstly, the "Warm Ring" in the NE PAC raises the stakes of early cold out breaks.  Secondly, the warm pocket of waters east of Hawaii may provide the fuel to develop tropical troubles late in the Hurricane Season and like last year, this may in fact fuel storms coming out of the Baja region.  If you look at the third map above for the month of October, it is advertising "sinking" motion over Mexico and the Baja region.  This is important as it will aid in the development of the new LRC pattern causing fuel to feed storm systems in the SW part of the U.S which then translates into the central CONUS.  Quite an interesting JMA seasonal run overall.

Jaster, Okwx,

Here's your shot of the day of snow.
Fellow said it was " Puking Snow" in Tasmania.

Enjoy!

Same here....hopefully, next year will be our Winter. I'll accept 6"+in a single storm and no questions asked.

Looking at the ECMWF/UKMET seasonal blend for precip anomalies during the Aug-Oct period on a global scale, some interesting factors may come into play early on in Autumn.  Notice the above normal precip across nearly all of Russia/Siberia and east into Alaska/Canada.  Is this a signal that the Snow Advance Index (SAI) will be rather impressive this year???  Fast start to winter in Canada???  Just another possible clue as we move along.

Ahhhhhhh, the Autumn, CF's coming down from Canada bringing w them that chilly, refreshing air and hearing the leaves that have already fallen from the trees fly around, making that sound. OK, back to heat and huimidity. That really cooled me off though for sec.

Based on your research, how far south will this early cool dip?
I'm wondering how soon Texas will see the back of this heat broken ?

Andie, I'm not Tom, but if I had to throw an opinion in the hat, I'd say less than a month.

The problem here is that we may also see it bring a tropical system back towards you and myself in the latter ranges of this. These pattern realignments are tricky sometimes when the pattern becomes disconnected in late summer. This is the period, (Aug-1 through Oct-1) that I struggle with the most.

My opinion is that this cold front is a "leader" of sorts. We'll see.
