Unless this data is wrong, then you are incorrect. 1983-84 winter was a -QBO winter.
-
I am not sure why most are not hopeful for this winter when you simply look at -ENSO winters, with -QBO, & early strat warming (1981, 1983, 1995, 2000, 2017, 2021). On average, longer winters than the +QBO years by far. All those years had good DEC (although +QBO DEC were better) but JAN was the coldest on average in the east. FEB dealt with -EPO & SER combo but yielded to good blocky, colder MAR on average. FEB warmest anomaly wise.

14 day forecast verification for PNA is pretty bad, more positive of the 14 day forecast...take note moving forward
-
PNA forecast staying closer to neutral now & not as deeply negative & trends positive in later: And, PNA for the most part keeps verifying above forecasts: FWIW

Hmmm....

https://www.meteonetwork.it/models/mjo/ I recommend Paul Roundy's site as well. You can look at the MJO in different portions of each month based off research. Both phases 7 & 8 have their best responses in weeks 3&4 of DEC https://www.atmos.albany.edu/facstaff/roundy/waves/rmmcyc/index200reg.html

BOM agrees...almost identical
-
Even the European model as well. Today 0z verses the 17th 0z. Am I saying we will not have massive SER problems? Nope but I am not saying we definitely will either.
-
For that reason, the climatology factor built into models is a factor in the low accuracy for now even in the medium range. GFS for 11/28 from the 14th model runs to today. Clearly, it is the expected to the observation:
-
Again, yea. Maybe you did not read my post closely. Last year was a La Nina. There was a deep -PDO. I predicted a -PNA dominated winter & a very warm, low snow east & several did. Despite that, the winter defied the odds & was dominated by +PNA. All I am saying is that its weather....not always just simple. So a little humility is needed.
-
Nearly a guidance is going more amped through 7 & then moving into 8 now. Canadian output is the lone exception
-
So what was your guess last year during a La Nina dominated by +PNA? PDO was even more negative at this point last year. Could it be more -PNA? Yes! Is it a given? No!
-
Can't you see how terrible that looks?? Its gotta be wrong until there's a run that has a deep trough in Cali & raging ridge in the East....then it's gospel. But do not worry, it is all objective with no subjectiveness at all. BTW, the posters I am messing with (you know who you are) I mean it all in total fun. You guys are actually really good posters!!

Locked & loaded

Phase 7 in DEC is usually a decent phase though??
-
-
Look at Region 1 & 2
-
Good ol Nina
-
15 day change
-
Phase 6-8 in DEC are not bad at all. 6 turns bad in JAN/FEB. A lot of misconceptions about MJO phases. Use Roundy's RMM: https://www.atmos.albany.edu/facstaff/roundy/waves/rmmcyc/index200reg.html
-
Temporarily that has relaxed. But when you have politicians start saying the world will end in 12 years, just 4 years ago, that usually generates the crazies.

0z GFS, end of month PAC to Atlantic HLT blocking
-
Also, I would add Weeklies is based on 0z data. There were noticeable 12z changes on EPS, GEFS, GEPS. Ridge not ridge gone on GEPS & less prevalent on EPS & GEFS than it was on 0z for the 11-15 day. It will be interesting to see the early period on tomorrow's Weeklies update.
