If the November runs show the exact same forcing then things will be interesting
-
It’s also been showing region 1+2 going into a La Niña since March

IMO the forcing moves east by December but that’s a wait and see obviously. And if I’m a betting man, the CANSIPS and UKMET show a super El Nino on the next updates like the Euro, JMA, POAMA already do. The CFS is also warming
-
The current strong WWB forming in the EPAC, which is going to initiate another DWKW and subsurface warming, the atmosphere finally (solidly) going into Nino “mode”, the projected -SOI round coming up and the start of an uptick in OHC again. The +IOD taking shape. The current OISST has a starting point of +1.25C in 3.4 before the new warming even begins, 1+2 at over +3.4C and 3 at over +1.8C
-
Yes. Agreed. The evidence is growing by the day that we are going to see a super trimonthly peak, most likely in the NDJ time frame. I’m still thinking the peak is in the +2.1C - +2.5C range
-
Right…..That’s why there’s this huge WWB right now #Clueless [emoji23][emoji23][emoji23] https://x.com/tylerjstanfield/status/1690786693232603136?s=46&t=NChJQK9_PUjA1K7D2SMojw

The OHC is coming back up. This MJO constructive interference should lead to a WWB/DWKW which will warm the subsurface and surface further. Also, looks like another -SOI round with substantial central PAC trade wind weakening is coming up. The models show the atmosphere clearly going into El Niño mode and strengthening over the next month. https://x.com/yellow_evan/status/1690429944969699329?s=46&t=NChJQK9_PUjA1K7D2SMojw https://x.com/yellow_evan/status/1690429944969699329?s=46&t=NChJQK9_PUjA1K7D2SMojw

This is going to trigger a new period of ENSO warming:
-

Nothing is impossible, all we can do is watch and wait. If I’m a betting man, the forcing moves east by December, given the factors I mentioned, plus the possible super El Niño and the record, extreme warmth in regions 1+2 and 3 but I guess stranger things have happened. There are no guarantees in weather….
-
I’m speaking of the Eastern Pacific El Niño evolution itself not the atmospheric forcing. The current forcing is almost certain to move east, as has been stated, once the ongoing Monsoon ends and the +IOD forms and strengthens. The current forcing is extremely likely not to just stagnant and be in the same place come December and thereafter given the changes about to take place
-
Nice write up and yes, as Paul Roundy has been stating, this El Niño is developing like the east-based/EP Nino’s prior to 1980. We are not accustomed to seeing a Nino develop in this way over the last 43+ years. I know some people aren’t going to want to hear it but it is extremely unlikely that the forcing is still in the same spot it’s in right now come December. The seasonal models are seeing the current forcing and just assuming that it’s going to stay right there for the next 7 months. The Monsoon ending is going to shift the forcing east as is the +IOD that’s currently taking shape and will be strengthening over the next few months. As far as the eastern regions (3 and 1+2), that warming is just reinforcing itself at this point through positive (Bjerknes) feedback. IOD:

I think one of the big factors back in the 15-16 winter was the insanely positive PDO, the GOA and western North American coast were on fire, IMO that lead to the temporary bouts of strong -EPO blocking we saw at times during that winter, which caused the cross-polar flow and arctic outbreaks
-
It goes without saying that there is a real heightened chance of a KU snow bomb in a super El Niño with the raging STJ. You just have to get lucky and time/thread the needle with an arctic outbreak and a phase (i.e., 83, 16). The pattern back in 1/16 was blatantly primed, you had the unmodified arctic outbreak with a banana high in SE Canada, -NAO/-AO, 50-50 vortex and it timed perfectly with the temporary -EPO (++PDO driven), -WPO and +PNA ridge pops out west. A snow bomb in an overall sea of warmth from the ++ENSO
-
In your hypothetical scenario yes, it would make things interesting possibly even with a super El Niño in place. However, I’m not so sure the WPAC will look exactly like it does now by December. Once the +IOD forcing really gets going I think the whole complexion changes out that way. All we can do is watch. That said, if we do in fact see a trimonthly ONI of +2.3C for NDJ, I still would not go with a cold winter, gotta agree with Griteater there
-
Let’s assume for a minute, hypothetically, the Euro is right, this Niño goes super, +2.3C ONI for NDJ, region 1+2 stays around +3.0C and region 3 is at +2.7C come December….Are you going with a cold and snowy east coast winter? I can see the argument that yes, we may thread the needle and get lucky with a KU snow bomb up the coast (i.e. 1983, 2016). As far as it being a cold winter with multiple snowstorms up the coast (i.e. 02-03, 09-10)? Color me very, very skeptical in that scenario. Sorry, but that would be a very hard sell for me
-
That’s not the CFS that’s the C3S. Given the new JMA, we are starting to see a consensus to a super El Nino
-
Here’s the new JMA, showing a super El Niño
-
The new C3S run is out
-
You don’t think ENSO events are easier to predict than forcing? While not an exact science, aside from the ultimate peak, it’s a lot easier to predict Nina’s and Nino’s months ahead
-
Once again, it is not even worth looking at model projected forcing 4+ months from now. This has been said ad nauseam. I don’t care what it shows for forcing, east-based, west-based, central-based. Once again, let’s see where the forcing is in November. Remember the great forcing the models were showing at this point in time for the 19-20 winter???
