Where did you get that?  Hasn’t updated on my source yet. 

I think this stuff is what spooked Don S.

Moving back to seven from eight. 

I admit it has been a bizzare winter.  I mean the hell with how much snow falls,  from a modeling and association point of view,  this has to be the worse winter ever for results that go against what you would normally expect.  I think certain long range forecasters have stopped posting out of the boy who cried wolf saying.  

For all I know a  blizzard could strike in March but damn these models are having the hardest time.

You know there have been 4 accumulating snow events in the last month for many in our sub. With a chance of another 2-3 in the next week. Some in the forum could very well hit climo by next Tuesday. But if you read the long range threads over the last month you’d think we haven’t gotten an inch and the winter has been a total fail.

It's funny all of the debbing all winter long yet a good chunk of the posters in this subforum are slowly getting closer to avg seasonal snowfall if not already slightly ahead. By the time winter is over several will be scratching their heads saying to themselves "wow, I dont remember that winter and all of the snow....it looked terrible on guidance the entire season".

the trend in this case is models having no clue wtf mjo is going to do

I'm disappointed in you...I've been teaching you all winter how to respond to people without directly responding to them. You were doing so well...no dessert for you

GFS MJO index forecast phase diagram

 

GFS ENSEMBLES - The MJO has been all over the map the past week.  From off the chart to diving to the center to now a loop back..  whats next?  made famous.

The thing is, that look around phase 8 should be a good thing.  Yea it retrogrades back into 7 but not until VERY late and I wouldn't put any stock into it.  The GEFS has been doing that for a long time and wrong.  Look at where we would be right now according to the last 15 day GEFS forecast vs now...

Even as recently as 48 hours ago the GEFS thought we would be looping around 6/7 right now and we are now into 8 just like the EPS showed.  I expect the GEFS to continue to correct.  Also...the statitical guidance based on analogs suggest progress into 8 and perhaps 1 is likely.  The constructed analog CA has been doing the best lately so maybe a loop in 8 is the right idea but it doesn't regress to 7 and looks to be progressing again at the end.  Besides...a loop in 8 is WHAT WE WANT!

statphase_full.gif.1b358f1cfd01c35e43037037c6386239.gif

But unfortunately that does not ensure results.  The EPS has been progressing the mjo through 8/1 and it has the trough stuck in the west also.  Maybe the euro does that due to bias, and the gfs does that because of mjo error.  I suppose... but I keep expecting the adjustment to the expected soi/mjo phase and it's going the other way right now honestly.  Either way the SOI has already tanked and stays that way for the next 10+ days.  There is subsidence all over the maritime continent, and the forcing is out near or east of the dateline on most guidance.  The problem here is not the mjo imo.  If we fail its something else.  It's possible that there is something else pumping the ridge in the east and that is shifting the pattern upstream vs us looking at the PAC and expecting changes downstream.  I honestly don't know.  I've seen recently others seem equally confused, some chalking it up to chaos, I've yet to see a good theory as to why we might not get the expected reaction to the soi/mjo.  Even Furtado hasn't mentioned any causality, simply an observed effect.

Trying to catch up. Did we recancel winter last night? And is the recancel before or after the 3 snow events in the next 6 days? Asking for a friend!

2 of those 3 are in the other thread.  The one in this thread is kind of approaching the near range edge of what I consider "long range".  But I hope people don't mistake the conversation and speculation I am having regarding the "long range" days 7-15 as having anything to do with our chances of snow from the 3 threats before that now entering the medium range.  

But at the same time... it is impossible to ignore the degradation of the pattern look week 2 right now.  Especially when I expected and predicted it would evolve towards more +PNA -NAO and eastern trough and it is going the exact opposite way right now on all guidance.   

Question... do you have any thoughts/opinions what might be driving the SE ridge?  With the SOI tanked and the MJO into 8 it's obviously not derived from the PAC tropical forcing.  Is it the downstream effect of the north PAC blocking ridge forcing the trough into the west...and if so why is that stuck there despite favorable pac forcing?  OR...is the SE ridge being caused by another forcing source and is blocking up the flow upstream and forcing the trough/ridge alignment out west to be where it is?  Any thoughts?

I'm at 55%, with 90% of the winter gone.

I don't think I've had a single Winter Storm Warning since 2016.

I have no idea why the SE ridge is so persistent in the ensembles. This has been a weird year. The 500mb height anomalies for the winter to date look fairly Ninoish as I recall, but there’s been a whole lot of Nina looks as well. I think maybe this winter will go down as a warm neutral with some Nina hangover, but it has a lot of unique elements to it. Adding in the early SSW just complicates it all. Regardless, it’s worked out fairly well for us and even barring the unicorn HECS we’re hunting, it looks like our region will probably end up 75-125% of normal snowfall.

NYC didn’t have a winter storm watch once from March 96 til December 2000.   The events were that putrid that even at 48-60 hours not one warranted a watch.  They never had a watch in January 2000 because they went right to a warning.

There are a few we know will DEB every year unless it’s 2003, 2010, or 2014. Basically that once every 7 years kind of anomaly where we get 200% snowfall is all that can keep them happy. The other 85% of the time they will be miserable. 

But this year there are still pockets of mediocrity around our region and some of the debbing is from them. CAPE has every right to be frustrated for instance.

As for me I go with the flow. When the pattern looks good and I think we have a good chance of snow I’m saying it looks good.  Go back to last year, I was getting complaints that I was being too positive sometimes.  I wasn’t debbing in early December.  I thought that pattern was legit we just missed.  And I didn’t deb the early January storm, I was one of the few that saw more upside than a weak waa wave from a few days away.  Just wish the northern edge had been 25 miles north of where it was! 

But when I see things I don’t like I say that too.  If you need a safe space and don’t like the honest truth both good AND BAD then put me on ignore.  But I don’t think saying things look bad when they actually do look bad is debbing. That’s being honest. Debbing are the people that put a negative spin on everything or are never satisfied unless it’s a HECS. 

Btw I’m not jumping off yet. We had a bad run. It could flip back. And we have legit snow threats before the crap look.  But what are we supposed to do when a crap run of guidance comes it?  Just ignore it and don’t talk about it so people can be blissfully ignorant?  I don’t get the complaining about “talking about bad runs”.

Agree on the retrospective, but with the soi mostly neutral to positive and the mjo cycling around 4-7 all winter the non nino features infecting the pattern made sense. I’m more confused to see a -soi mjo phase 8 and still not get the typical pattern response.

Your posts are well balanced psu.  I think you have to present the good and the bad.  

Just because I mention a negative does not mean I am cancelling winter threats out there in the long range.  But, discounting bad runs, or trends and sugar coating things is not cool, then you are biased. 

I think the purpose of this thread is the long range and the good and bad.  It is also a platform to ask questions about the long range, learn from one another and seek answers to things that are relevant regarding the weather patterns and drivers that guide the long range forecats for our forum.

I am going to bring over to this thread some good insights about the PAC and the evolution of the SSWE,  It seems to touch on some things you were talking about.  Does not answer everything but touches on some good theories.  I am going to look around today about the SE ridge you brought up a little while ago.

I think it is the poor performance in the long range and also the expectations for the winter that have combined to sour people.  I really do think that whatever happens the rest of the winter is unknown.  I wouldn't be surprised if it was a gangbusters end and also wouldn't be surprised to see an early spring.  Extremes are really becoming the norm, IMO.

the question isn't whether i'll remember the snow, it's whether i'll remember the snow or rain MORE

the next few weeks will determine that

this is where i'm at.  we got one good snowstorm.  aside from that, there's been a lot of snow left on the table because of all the rainers.  let's see if the next couple weeks can turn the tide.  if not, then just bring on spring...at least there's a good chance it'll be lush.
