Yes.

Well stated.

Right - best laid plans ... LOL

In this business, if 'laid' means how we take it after having implemented the most lucid rational, objective route?  Sure.

No, but ... yes, if I was forecasting February, I'd slope pretty significantly warmer and dryer than normal ..roughly the 10th - 20th...25th ( perhaps the rest of the way).   But, I would put my probability at say, 70% ?  

I don't have a formal arithmetic in that number - it's more a super duper amazing sciency approach of how I 'feel' about this stuff at this time. However, I did elucidate some pretty damning reasoning ( above) so it's valid conceptually based upon that foundation.

I am pretty happy with how my December thoughts played out, dearth of snowfall be damned...and think I am on the right track for Feb. Unfortunately, all I got right in January was the active storm track....problem is it was like +8 instead of normal. Of course.....the shit part works out.

Great-

This may only have symbolic value - not sure... - but something I've noticed in the past.

When there is an advent of some extreme, ...if you are looking for it, you may notice either in aggregate or all at once, there is compensating event(s) that takes place within weeks, short weeks sometimes, that follow the dramatic departure advent. 

In a pure bean counter perspective that makes sense.  The climate is not representative of the extreme. Something has to atone.

( otherwise ... you're climate is changing - haha)

If we knife in a -3SD knuckle stinger, but it's back over 30 just 24 hours later, heading ( probably ) for a week of sustained 40s - cloud and cat paws permitting - the cold is atoned for by the following Thursday or something. 

It reminds me of that.

Man, we have really just rolled snake eyes this year....uber NAO block in December....that interacts with the PV in such a manner that all of the energy phases west.

+PNA January....that is biased west and off of the coast, so that a semi-permanent trough remains anchored along the west coast.

-AO January.....that teams with a +NAO to focus all of the cold in Siberia like Jan 2002.

Now Feb begins with a historic arctic blast that squashes the storm track, until it lifts out in time to rain.

"Just a bit ironic....don't ya think"

I think the tropics have dictated that you take the under on amplification when the MJO is in the wheelhouse phases for eastern weenies, and the over when in the milder phases.

That is the gist of my next blog.

I know SE ridging is always a risk in Ninas, but I didn’t think it would make it all the way up to us especially with the look we had in early December. It’s strange how despite the Nina being borderline moderate, it’s acting like a very strong one with no blocking (post December). Looking at the SSTs it looks like the Nina transitioned from east leaning basin wide to a more west based Nina. I know that isn’t good for us, but I’m curious about what the warning signs were that the Nina would shift west and influence our pattern in a way that resulted in a mild winter with below normal snow. I do agree with you that we got unlucky, but especially post December the longwave pattern has been awful.

Human kind's throught process is still far too linear for seasonal forecasting....too many generic relationships, indexes and correlations are over simplified, which leads us astray.

Whereas, though I do not formally publish my season thoughts ... I do in snark sometimes proffer some obnoxious, borderline troll - but not specifically because I like to engage in that practice, just that by default, my position ( partially rooted in how I really feel) may oppose the consensus.

In this case, I didn't see how this winter would be 'better' than last.   I really didn't.  Come hell or high water, I figured it for a forced affair with a larger clearly physically outclassing prison associate, when it comes to winter enthusiasm. 

People have their ways and means... but, I do admit to believing the folding/block tendency of the autumn and spring is a real aspect that is reproducible, and in between those, we have been also repeating fast flow that rips at the standard cyclone model ( in the means ) - all this as strongly motivating tendency, by all factors in mind, to recur.  Ranging from those are conventional, to those that are in research.  

I don't bother to put this down on proverbial paper and post seasonal outlooks.   I observe too much vitriol between those that advance these outlooks - it seems like doing so is allegorical to raising your hand at all on Vieques Island - a.k.a ('Lord of The Flies').   There's a petty kind of celebrity seeking competition in that space that's not really ever even going to have a very positive return - nothing anyone does in here or in social media, in the space of season forecasting is going to seat one next to a 'star' of Meteorology or in general. 

Ahgh... don't mind me.  I'm leaning more and more into existential nihilism with age.

You should put something out next year...you have a ton to offer, John.

I mentioned this last week regarding the MJO. This year, the cold phases were phases 3-5. The warmer phases that torched us, especially regarding the PAC jet, were the typical cold phases. 8-2. Nor sure why, but pattern recognition was important to help identify cold shots. 

I'll admit this is something that I need to pay more attention to in season....when the winter goes the unsavory route, I tend to check out and not pay much attention, aside from brieg blog update cameos.

I definitely agreed with you Scott, when you did - I recall you're statement.  In fact, dig it up - don't be surprised if I pinged you back the appropriate emoji ...

It's just that I guess it was like reading the recipe and thinking that sounds like the right kind of meal, but now one can really smell it cooking and it's very palatable - haha

Oh yeah...wasn't trying to beat my chest or anything, just something I noticed and I saw come up with some energy Mets. It's interesting for sure.

 

But, I don't think it explains why we have been absolutely bent over from a temp and snow point of view this season. This is quite an enigma to me.

Pretty nice high building down into the system in la la land on the op gfs. Shows how it can be done atleast with cold lurking over the border

I know ...

As though in great homage to the 'best laid plans' conversation Ray and I were just having... the 11th comes back in the GFS.  It's 270 so it's more for the comedy for now but this is tooth-aching sweet looking

There’s been a lot of scooter highs in clown range the past few runs. It kind of fits the pattern though…I know it’s popular in here right now to forecast non-stop warmth for February but it’s really hard to get all-out furnaces when you still have some cross polar flow into Canada. Its the type of pattern that will be mild in the mean, but there could be bouts of colder intrusion. 
 

We’ll see though….maybe the cross polar flow shuts off and if it does, then it could torch more without interruption.

Man UKMET kind of says fuck 50s and 60s, eat some 20s and 30s......

Does it help I will be turning 60 ( god that's a scary thought!)  on the 11th?  Ha Ha, maybe a birthday surprise!

I believe MJO is still showing up according to its phases but it’s with a background that is ++AN. It’s therefore muting the cold aspect, and making it harder to notice relative to climo. But it’s there.

We saw signs of this for 1 week in mid December (phase 1/8), ~5 days in Jan (phase 8), which was topped off by the weird (978mb coastal) that backed into Maine.

And now with the MJO in phase 4 we’re seeing it again, with 4 days BN, topped off by PV arctic blast. But this goes right back to ++AN.

MJO is loud noise; not a signal of pattern change.
