Shit....I forgot I was in the Sept. thread...my bad. I early hunch on how the unprecedented magnitude of ENSO will factor in is one word...VOLATILITY. When you have those type of anomalies throughout the basin, it's going to introduce a myriad of different forcing schemes along with a very prominent and loaded STJ.....line it all up nicely, and the sky is the limit....but don't blink, or it will melt and you'll miss it.

It looks like someone smashed someones Lego’s?

The size of the +28C to +29C water temperatures within the Tropical Pacific is ridiculous. Even +20C off Mexico and into the Baja.

Adding on to my reply to Scott in your winter thread about the ridiculous graphic from the annoying guy and how some of the stuff he says doesn't seem to make sense. He is favoring increased winter threats in the deep South because the jet will be shifted south. I don't think that is totally true but I do know alot of generic stuff out there on EL Nino mentions this. I think there seems to be confusion out there on the different branches of the jet stream. The cooler/wetter patterns which plague the southern states during EL Nino I think is related a a stronger jet (which we all know) but its a stronger sub-tropical jet stream which can have the tendency to be displaced a bit further NORTH and its the cooler/more active track which plays a bigger role in the temperature anomalies. But its the stronger jet which is more critical versus the displacement. The polar jet also tends to be displaced further north, hence the lack of Arctic cold outbreaks penetrating south.

Those posts in the Sept thread probably should be on here lol.

It feels great outside to me. Nice breeze and since it is just 80, the dews don't feel bad at all. Looking forward to logging off work in an hour to enjoy the long weekend.

Maybe it is as simple as that, who knows. But it’s such a huge expanse of warm water. Just a little hesitant in applying that thinking.

I was thinking like some sort of tropical-thingy zipping NW. AKA October 2021.

Given the pace of the tropical season, there isn't much to catch up on. Three blogs, though the last two are very deep.

Agreed. The prospects for anything seem super slim...would need something to probably form along a stalled front...no waves are going to make it that far west, especially considering the shear should only continue strengthening through the MDR

My feeling is that more often than not, we are going to struggle with precip type, but the region still may very well score climo snowfall from the couple of events in which we do not have that issue.

For CT at least, July 4th was a pretty big widespread severe event day. Otherwise, pretty much crickets. It's not that it's quiet, it's that north south and west of us have had big years. Hell, even the fish have seen better storms than some of us. Going to need a lot more than warm SSTs for something off the coast. Tropical waves can't get to the western Atlantic because shear is absolutely obliterating them. Dolly formed, ran into a buzzsaw, and even when it found a favorable environment off the SE coast it couldn't do anything because there was nothing left. Going to need either a well-timed wave to make it through the gauntlet into the Bahamas late September or a CAG system yanked north in October. Anything popping off a stalled front is just going to pass well OTS. 20-30 years of a quiet(er) Atlantic...

Get out of my head.

That is exactly what I am grappling with. If your thinking is fixed firmly within the box with respect to seasonal forecasting, then your final forecast product is likely to suffer a large degree of error.

I will say that @Typhoon Tipwere musing just yesterday about a theoretical "unicorn-scenario" in which the residual cool ENSO residue retards the development of said GOA low in such a manner as to allow for that. Said impact would need to be both more subtle than 2023 and more apparent than 2015.

I know some people will say well it will just supercharge whatever we had for a strong or super Niño. I’m not sure you can apply that linear logic.

Great stuff. I am curious as to what influence the northern Pacific will have on the Arctic domain this winter. Obviously the are backing off the vast -PDO regime we had been in, with help to the developing EL Nino but we are in unique territory regarding the state of the PDO. This is a situation where I don't think a raw numerical values tells the entire story here. Clearly we're heading towards more in the way of a +PDO structure but those absurdly warm anomalies from Japan across the north Pacific IMO still reflect which is by large a -PDO. Based on how the EL Nino has developed, combined with the state of the Pacific, my anticipation would be an significantly far north sub tropical jet this winter and once that is very juiced. Now, that is something that could bode well for us if the cards align but we'd also be talking about a raging jet and it may be very difficult to get surges of Arctic air to displace southwards. I would have to think we would need to see a -NAO/AO of historic territory to give any shot. Even if we did get a -NAO during the winter, it may not be much help and if anything could increase potential for warmth if its structured in a way where the above average heights connect with the jet and propels it even further north.

I am usually lethal with ENSO forecasting, but I will say that the unparalleled magnitude of this El Nino is really posing a challenge for me with respect to any forecast precision beyond the blanket "super-El Nino designation. I am someone who exhaustively parses data to come up with analogs to inform future intensity forecasts and it makes it difficult given that this one is in a class of one. Def. take my exact numbers with a grain of salt this year.

If you could tell me that the GOA low will be just west enough or perhaps not as strong as some are anticipating so that if we do get a negative NAO, there’s a little bit of a cold source in Canada, I would definitely have a change in attitude. We obviously do not need Canada to be an icebox, I think we all agree on that. But what I worry about is that we have this split flow totally void of any money in the bank in Canada and raging STJ that basically combines up with any negative NAO ridging. if I would make a call, I would have BN snowfall, but I’m not anticipating a massive skunk in terms of snowfall. Especially the interior.

Long loss of power means refrigerators and food may not be kept cold. Not every school has UPS/back up generators. It's cautionary to mitigation food borne illness.

True, that is how I feel.

Well it’s also based on previous types of ninos. I did say I’m not opposed to near normal snowfall, but I’m not optimistic on AN snow. That’s different than Kevin claiming how every winter will suck. I’m not going by emotion.

Presto: 30 Day change:
