What are the potential effects of a high solar flux given the current background states? I really haven’t read too much into the solar aspects

Judah…..lmfaooooo hahahahaha What do JB and Henry Margusity say? Lol

No, you really don’t lol and 10-11 was a 1st year Niña coming off a Niño and it was +QBO lol

Once again, courtesy of the WAR, the cold can only progress so far east. Deja Vu of the last few years….the models are way too cold in the extended only to correct warmer the closer we get

You have no idea what you’re even talking about, literally none. 11-12 was -QBO also

Those SSTs along and off the east coast aren’t just warm, they are record warm. They are going to feedback into the WAR and SE ridge. Also, unlike last year, we have a very well coupled and strengthening La Niña, along with a strong -PDO and -PMM. Any +PNA is not going to sustain itself like last year, any PNA spike is going to be transient

@bluewaveOnce again, the models are correcting to the WAR as we get closer to the beginning of November. What once appeared “cold” in the long range isn’t so cold anymore

This is exactly why I would be hesitant to predict a cold November in the east. The SE ridge/WAR are feeding off those record super warm SSTs along and off the east coast, a positive feedback loop is in place. I also do not think you are going to sustain +PNA this time around, you have a coupled, strengthening La Niña, a very strong -PDO and a -PMM, any +PNA isn’t gong to be around very long

The problem is that some folks on Twitter are advertising that November is going to be a deep arctic freeze. That couldn’t be further from reality. It goes from insanely above normal to normal, maybe slightly below. You need to seed Canada with cold and that will take awhile. When we start November, all the air is still PAC maritime origin, not arctic or Siberian origin

It’s going to be PAC origin air until Canada gets seeded with cold, which is going to take awhile. You are going to need extended -EPO to do that. Transient -EPO won’t get it done

Some on twitter are in panic mode right now that this event may go moderate and also be a late peak

Those super warm SSTs are positively feeding back into the SE ridge/WAR. Given the La Niña/-PDO and those SSTs off the east coast, I think the SE ridge is going to be a big player this winter

Mike Masco is Joe Bastardi Jr lol

I read that paper, good stuff. The questions now become, 1, after the upcoming recovery, how strong does the vortex become by the end of November/beginning of December and 2, are there more warmings coming down the road?

Great post. I’m seeing tweets from amateurs proclaiming that it’s going to get cold, all they see is a +PNA and -NAO and think that means cold….not when all you’re doing is trapping PAC maritime air with the blocks….cooler? Yes. Cold? Not with that setup, the EPO is still +

You don’t believe that if it wasn’t for the SSW, that would have been a horrible winter? It saved February

The only thing that saved last winter from being a wall to wall dumpster fire was the SSWE in January that gave us 3 weeks of winter in February (2/1-2/22). It was a 3 week winter, the one lone snowstorm in mid-December that was melted down to nothing in less a week, 60’s on Christmas Eve. Nothing at all in January, nothing at all in March. Had it not been for that SSW, it would have been one of the worst winters of all time, right up there with 97-98, 01-02 and 11-12

I never made a winter forecast last year lol

If it gets colder later next month it will come from a PAC reshuffle with the tropical convective forcing, not from some crazy SSW and super weak SPV like Joe Bastardi has been hyping to no end for the last 2 months. His wishcast of a major SSW/super weak SPV causing an uber cold November - January looks to be an epic fail incoming

Evidence is mounting for a rebound and strengthening of the SPV next month:

Yep, we’ve been hearing that the +PNA/-EPO pattern has been coming since September 1st…..eventually it will get here….

If he’s correct and a AK/GOA vortex is a persistent, semi-permanent feature this winter, we are in a lot of trouble. An AK/GOA vortex is a mega torch pattern for the CONUS and Canada

Yea, I would definitely not be comfortable forecasting a cold and or snowy November in the east right now, after weakening initially early in November, the SPV looks to completely recover and strengthen by month’s end. Also, you have a coupled, strengthening La Niña, strong -PDO, -PMM and the SSTs along and off the east coast are blazing right now, they are going to help feedback into the WAR/SE ridge. The PAC has wanted to stay -PNA/+EPO/+SOI since the beginning of September, it’s been a very persistent, stagnant pattern there. Also, unlike last year’s east-based event, this Niña is definitely more central-based:

There are actually signs now that after an initial weakening of the SPV in early November, that it recovers and becomes strong and the stratosphere goes cold by the end of the month:

Not necessarily, there have been warmer than normal October and November in the past that lead to cold/snowy winters. The problem is when all 3 months (September, October, November) are warmer than normal, that it almost always leads to a bad outcome
