So you have to extrapolate this forward knowing there are already warm SSTs present across the WPAC along with a +IOD/+SIOD and +PMM, all of which, together, favors WPAC/dateline convection and future WWB activity. So it’s hard to deny (IMO) that a trend towards +ENSO is heavily favored on the spectrum of probabilities.

Phil Posted September 8, 2019 Report Share Posted September 8, 2019 But the Indo-Pacific (~120E) waters certainly have been “drained” of OHC over the last decade, where most years have below average SSTs/OHC there. FWIW, this is a signal that also shows up in the paleo data preceding every NH cold event since deglaciation, usually by a few decades. Pretty much a mandatory precursor signal.

Yep, shoot me.Well I wouldn’t say niño yet (for this winter). But I suppose a weak west based/modoki type niño is a possibility. Key is that warm subsurface waters will (probably) be building in the WPAC in the O/N/D period..and since we didn’t progress into a mod/strong niño this year, it will probably happen next year (Solar driven IPWP cycle tied to ENSO/MM tendencies). Which would make 2021/22 the start of the next multiyear La Niña/-PDO/-PMM cycle.

Or as its calculated, the Modoki scale, I guess. Hence likely the cause for the negative SOI. The temp profile (contrast between 1.2 and 3 3.4 and 4) shows like a too far west-based Niño unless that eastern side warms and mellows the contrast down a tad. The waters warming so rapidly southwest of Mexico are an indicator, also, that it's going to be hard to keep a weak-mod Niño off the table for long. In blunt English, it looks pretty sh!tty for anyone but the NE, Great Lakes and N. Central states unless we get the west coast ridge to stand up and teleconnect. If that happens, though, the west coast gets screwed. 1 Quote Link to comment Share on other sites More sharing options...

I can assure you that all of our coldest and snowiest winters on record had lots of cold rain as well. And I’m ok with that, because its part of the winter package around here, even during the greats. Plus it’s fun to be able to visit feet of powder just an hour away in the mountains even when there’s nothing in the lowlands. I don’t think anyone said they would prefer rain to snow when given the choice, though. 1 Quote Link to comment Share on other sites More sharing options...

BhamMe Posted September 12, 2019 Report Share Posted September 12, 2019 The weather folks at KOMO 4 in Seattle, posted this today. https://komonews.com/weather/scotts-weather-blog/noaa-odds-of-el-nino-less-winter-increase NOAA: Odds of El Niño-less winter increase SEATTLE -- 2019's version of El Niño officially died last month, and now forecasters say the odds of it potentially coming back for this fall and/or winter are even less than they were then.The Climate Prediction Center now gives a 75% chance that we will stay in neutral conditions -- essentially meaning near-normal water temperatures in the tropical Pacific Ocean -- through the fall, with around a 55-60% chance we'll stay that way through the winter.El Niño now has just under a 30% chance of returning, with odds of a flip to the cooler La Niña conditions hanging around 13-14%.Neutral winters are challenging in the sense that they don't present any steady historical patterns of which to base a good long range forecast like El Niño (warm/dry) and La Niña (cool/wet).Historically speaking, neutral years tend to bring more frequent strong flooding events. Neutral years have a good news/bad news relationship with windstorms as strong wind events tend to be most frequent in La Niña years for most spots, but neutral years tend to have the strongest storms.For those eager to hear about lowland snow, neutral years don't really provide much of a clue as past neutral winters have run the gamut. If the new Blob sticks around, that would hurt snow chances but the Old Farmer's Almanac says look out, snow. So... lots of ways that could go. Mountain snowpack also tends to range quite a bit but we would expect it to be within 20 percent either above or below normal. Quote Link to comment Share on other sites More sharing options...
