Yeah, 65 here too. It feels glorious, ngl.

Then the gfs spits this out after I said that of course. Clown range here, but the interesting thing about this, the eps has a couple clusters that show something similar to this too. May be nothing, but worth a mention I think.

Just starting today and going ahead, the ssw will now be included in the initial conditions on modeling. So it will be interesting to see what changes, if anything, as that becomes the case now. There's evidence available that suggests this makes a noticeable difference with predictability of how they play out. I'm not saying to expect anything crazy, just that this is a point where potential changes could occur on modeling. Or not lol.

Yeah, I've been saying it's not really impressive looking.... The latest gfs cross sections suggest this is not making much progress downward. Best to wait until it's underway and then see what models are doing, though. But it just looks uninspiring to me so far.

Toss that MJO idea to the moon. Not happening. It's not going to be effective....

Weaker walker circulation is just not good, maybe. We want some amplitude, but too much isn't good either. It's interesting to think about.

I like a weak to moderate modoki el nino next year. We're following EOF2 from the following paper fairly well. Which leads to that. I agree neutral isn't off the table just yet. Whatever it is, it is not similar to EOF1. Which leads to the east based classic events. Leading modes of tropical Pacific subsurface ocean temperature and associations with two types of El Nino https://www.nature.com/articles/srep42371

Yes, this is usually my rule of thumb with that. It's funny too, I thought this winter would suck back in August. Then the blocking became a possibility and I reconsidered everything lol. Because blocking is what you look for in la Nina if it's going to be any good. That was an interesting development. It failed, sometimes they do. Is what it is. Swap neutral and moderate la nina with each other and I agree. Neutral sucks, too strong in either direction does too. Just a very basic guideline. Many other variables to consider.

It does look like the ssw is going to actually go off. Meeting the technical wind reversal definition. In addition to the eps, the GEFS is now 100% for the past few runs now. Will be interesting to see how/if it works with the troposphere following this. Be curious to see some cross sections on what is happening once this gets underway. Never can be certain with these things but worth keeping tabs on. It's something to watch at least. Hope everyone enjoys this very nice mild Friday on tap.

Well, it can't get much worse I don't hate la nina. Some of them can be good. This one just has it all wrong lol. Tired of it though, I welcome a change.

Here's a great example of why extreme caution is always needed with those charts. If we look at what is actually occurring on the model. We can see the MJO wave moving right along. However, we can also see the warm pool convection associated with la nina never fades away enough as this is occurring. This renders the whole thing less effective. This is the destructive interference we sometimes mention. We'd really want something strong enough to fully disrupt that in order for more meaningful changes. Something we just haven't seen much this year. So that forecast crashing into the COD is really trying to say it's retaining its dominance in spite of the MJO. Which is a problem for us this year. That positioning right there is the anchor for a western trough. So we end up stuck with that as much as we are. Now, let's shift that thing closer to the central Pacific next year hopefully. Then you get a western ridge instead.

Not sold yet on a technical ssw even occurring. Some warming, sure, but the gefs seems to have backed down on wind reversal today at 00z. Plus, the 06z run now only has 60% of the members on board with it. So it's still possible it doesn't even occur this time either. I realize the eps weeklies were bullish yesterday. However, I'd prefer to see total agreement. Not going the other direction. Especially as we're getting inside of day 10 now. You'd really want to see a strong event too in hopes of impacting where it matters. This is just uninspiring so far IMO. I also agree with the sentiment that even if one should occur, it doesn't necessarily have to matter for us. This is always the case and should be baked into any thinking about this topic any year.

The purpose of the long range pattern discussions is not to identify any individual storm systems. I personally think it's a misinterpretation to think of it in that way. You can get snow events in a bad pattern. Nobody has said that can't happen. I certainly haven't. The thing is, favorable longwave patterns offer an easier path to accomplish the certain combinations of synoptic features we're all in search of. That is the reason why they are often discussed. Not to identify anything specific. At least it shouldn't be. It's simply an attempt to identify windows where it's easier to find something specific. It's really two separate things, in my view.

0F IMBY currently. That's impressive here on CAA. Usually that happens with rad cooling here. Yesterdays hrrr did alright locally here. Euro too.
