We got lucky! Incredible!!! Photo is a photo from the back of my camera. Good luck all!

Wow, you even captured the diamond ring effect!

Yet another deck incoming, when just a few minutes ago everything looked clear.  Pretty sure it’ll stay thin enough. 35% coverage

Scattered clouds over the immediate DC metro... go away!

Think this cloud deck went over me before you,  but i could still see the sun through, so its mostly fine

now clearing up here (ashburn)

Skies appear to be opening up. Game on!

20% coverage now

lol blech. Almost overcast with 20 mins to go.

Thicker layer of clouds incoming 

First contact made. 5% of sun clipped off

can see through the thin layer of clouds

Breaks in clouds, growing more confident that I’ll see a partial eclipse with special sunglasses at around 3-3:30 pm

Latest NMME has a -PDO in Dec (no surprise). I see no reason to not remain firm at least as of now on a -PDO next winter.

Zero signs that the Japanese marine heat wave is ending. Looks like a carbon copy of 2022-23

Low of 34, but frost everywhere. 

Just graded my 23-24 winter outlook:

Grading my 23-24 winter outlook vs actual results

Temperatures: Decent match spatially, but off on the magnitude of the warmth. It's not just us being really warm, it's everywhere. Including Canada. Grade: B-

Precipitation: Good match spatially and magnitude, a little bit off on the precip maxes though both midwest and east coast. I was highly confident of a wet winter, and that did happen. Grade: A-

Snowfall: Truth is, I had at least one big storm baked into my snowfall outlook even through I cited only a 15-30% chance of a HECS. Well, that didn't happen obviously, so my snowfall guess was shot to hell. Grade: F

Overall: I think my methodology and use of MEI led to an OK outlook, but was a little overconfident on blocking. We did get blocking, but each episode was either too brief, or occurred in the wrong places. Unfortunately, the MEI is no more, and I will have to either use RONI or a different method altogether for next year's outlook. Overall grade: C

Nothing went wrong. Only thing that was wrong were the humans trying to predict the future. Totally normal winter and probably better then the past few. 

Yeah, I’d have to compare my conus temp/precip maps in my outlook vs actual, should be a decent match. What went wrong was my snowfall outlook had baked in at least one big storm. Which didn’t happen.

Low of 27

Low of 29. No frost because its so dry

Smoke in ashburn. Where are the fires?

There are already signs that La Niña is developing, the subsurface is currently -0.6 C and ENSO regions 1.2 and 3 are plummeting. Does the Niña developing this early give us some information about the likely strength next winter? 

Early peak and decay may give us a modoki nina, worst case scenario for the east if you like cold and snow. 

Repeat of last years canada wildfires?

Yes, it's happened in 1973, 1988, 1998, and 2010 - the four years that transitioned from a strong or super el nino into a strong la nina.

Thanks, that gives me a clue to which analogs would make a good starting set and add others based on QBO and PDO (and of course, adjust each warmer by a couple degrees...)

Latest CPC ENSO Probability: 

Quite the turnaround. >60% nino to >60% nina within 3 months. Has such a transition happened that quickly before?

If we could end up with a +2 next winter, it would feel like living in the Arctic compared to these past two winters. 

Still a warm signal. Even if only +2 based on older analogs (pre 2016 super nino), one would need to adjust to today’s climate. Like +4 or something like that.

LOL. Now we are.......two weeks away! And out to March 26!! If we just keep going long enough, we can get back to December!

That’s not wrong

This development is disappointing. I'm not sure why the MEI can't be reconstructed using the JRA-3Q dataset (the successor of the discontinued JRA-55). Of course, if the new dataset excludes one or more variables used in the calculation, that's a different matter.

Yeah, I was disappointed as well. Even though I busted way too high on my snowfall outlook, looking back at how I based my CONUS temp and precip maps on the MEI, I think it actually proved an useful tool that led to fairly successful verification at least with the distribution of temp/precip anomalies. Enough to make me think that I can use it again in future outlooks... then they take it away.

Well MEI data will no longer be updated...

https://psl.noaa.gov/enso/mei/

Wow, that is news. I guess I won't be using the MEI for future outlooks then. Might have to go with RONI or use my own custom dataset or something.

That escalated quickly.

Bring it on. 

I'm not expecting a winter next year imby, so might as well go ape with this nina and hopefully the strong trades push those cooler waters all the way into the maritime content / west pacific warm pool while we're at it.

Saw a few flurries yesterday afternoon and lots of wind this morning

Next winter the sfc temp anomaly may look pretty much like this map if the pacific doesn't change and we get a +qbo nina. Could be historically warm and snowless for the immediate east coast up to coastal SNE. 

At some point, we've gotta get a dip that breaks the climo trend. Don't know when that's gonna be.
