Yeah, it's not as easily baked into the price as you would think. They do a lot of year-to-year consistency. If next year there is a -8 SLP over the Arctic June - August and Natural gas is $2.50, it would be good to go long the position for the Winter.

Natural Gas Futures are up near $5, making one heck of a run since August! I've been watching to see if it goes up, record low 500mb in the N. Hemisphere in August, low 500mb at different times in the Summer and Fall - all that is pretty strong in preceding a cold Winter. Since 2012, negative SLP 60-90N in the warm season correlates to Winter -AO at a high rate. I didn't trade the Futures, but I should have - they are trending toward the colder Winter idea (although $5.00 is about the middle mark - >$5 -NAO, <$5 +NAO)

Doesn't make sense - they have 2" for Bel Air, then 43% of getting 1"+ 1" is much more realistic around here - the 12z GFS looks like ~1", less SE

This isn't a real strong Stratosphere warming so far

That model is too cold.. it has me >30% of having 3"+.. it's going to be rain here. There is a storm around 12-6 though, and maybe another later on.

It may just be a brief pattern though, like a few days. I think 36 hours ago the ensemble mean had the coldest anomalies over the PNW, where it's now Alaska so it's been moving around a little bit. A +EPO can overwhelm +PNA/-NAO.. btw, NAO is SLP between ~Iceland and the Azores. That's +NAO being shown, but -AO (High pressure over the arctic circle). Not really a strong anomaly pattern coming up.. hard to make a forecast in all that neutrality. I do like the overall cold 500mb in the N. Hemisphere though.

I'm liking the cold tendency (-AO tendency) this cold season. Something like 97-98 and 01-02 are the farthest thing from right now. Notice how the modeled 500mb maps have more cold than warm anomalies in the N. Hemisphere.. we haven't seen that in like 10 years. When I researched snowfall in Winter the N. Hemisphere negative 500mb (general) was the strongest thing preceding. I'm trepidacious about an above average snowfall Winter down here, but we do have a better pattern coming compared to the last 10 years imo. Anyway, good job on your analog outlook.

The +EPO and cold probably isn't going to happen like that.. it's going to be one or another. If the negative 500mb over Alaska holds in the next few days, models will probably trend warmer in the CONUS. CPC yesterday put out a cold 3-4 week forecast though, with above average precip

You going to get 3"? Glad I didn't bet you. The strong -PNA/+NAO being modeled didn't really happen.

Honestly if Lamar is injured they should have been upfront with it, and left Huntley in. He played great in our biggest win of the season, against the 8-3 Bears. Lamar has 0TD in the last 3 games.

Yeah but they fumbled at the 1 one yard line which is a turnover although the defense never maintains possession (stupid rule - it should be offenses ball at the 20), and a kind of stupid offensive pass interference.. or it's 21 points in the 1st half.

I think we may need something else to happen. Strong El Nino's don't actually have a very high correlation with the PDO. You would think that ENSO would be more correlated to the PDO, since PNA is a main effect that comes to mind, but it only has 0.3-4 correlation. The two aren't actually as interchangeable as you would think. ^That's the 6 strongest El Nino's since 1950. ENSO more effects the actual North Pacific High, where the Pacific currents associated with the PDO are west of that.

90E being +6c anomalies at -130m may definitely precede an El Nino in the next 1-3 years. A few strong Kelvin waves would probably warm the entire ENSO subsurface pretty good.

At this time of the year cold air is the most important variable. -EPO is the best pattern for this. This is what the ideal pattern looks like at 500mb: The 12z GFS kind of has the -EPO pattern, although it's a little SW, which may ultimately create a little more of a SE ridge and a little more mixing or rain where the model currently has snow. Pretty close though.

Wow, Pacific pattern is completely different.

I think that's because there's a -EPO a few days before. It takes the US pattern a few days to change after the Pacific changes, but that pattern is going warm. I guess the N. Pacific ridge heading a little polar could keep it cool enough near the Great Lakes. The longer that storm takes to get here, the more likely it is for rain. We want it early while there's still a -EPO in place pushing down a strong High pressure.

We've gotten snow when there is +300dm over the Aleutian islands and -250dm just south of Greenland on Dec 5.. like never. I look at that map and say the opposite is what we want. Look how there's even 4 cold waves around the N. Pacific RNA (established).

12z GFS brough back the -EPO for early Dec Nice High pressure location.. but this is just one run

I mean if that MJO forecast verifies, it will be a weird Pacific H5 for what the MJO is. Something to watch to see if that happens: MJO amped in 7-8 and a -PNA/+AO pattern

CFS runs 4x a day, and sometimes it will have the whole US below at 12z then the whole US above at 18z. Running more helps tracking scores to improve for more data.. but 2-4 week models haven't proven much more accurate than seasonal models to this point. I personally like the 384hr map on the ensemble means, seeing what the NAO, PNA, AO patterns look like.. that is pretty accurate. There is a pretty big model drop off after Day 15. Maybe they will continue to upgrade the Euro ensembles, but they have had some big misses since coming into inception several years ago.

Remember how bad they were in 23-24? The 2-4 week period still has lot of work to do for more predictable models. There was a time in August when the weeklies had +5 around the Great Lakes and Upper Midwest for a 2-week period, and it ended up being like -5. Also, for all talk Strong Nino's get about having warm December's, you rarely hear about La Nina's and cold December's, but they do go hand-in-hand. But like I said a few days ago, when the -EPO ridge retrogrades and models want to significantly cool Alaska and NW Canada thereafter, that is a warmer pattern coming.

CPC said last Winter was the most +PNA Winter or record for a non-El Nino. Fwiw, there was a pretty -PNA period Jan 15 - Feb 10 that they were calling +PNA, but on these correlation maps what they say the index is what's used for correlations. I found it interesting that one year after most +PNA Winter's there isn't a +PNA signal the following Winter.. actually there is +NOI (+North Pacific High - the high pressure off the west coast), and that indicates more of a La Nina pattern... it was slightly predicting a la nina this winter. 1 December after last Dec +PNA... Fwiw, Jan +1 year doesn't reverse like December usually does

Dec 2021 was one of the strongest -PNA's.. what I see on models right now is a "moderate -PNA event" in early Dec. I also don't know that it sustains beyond like a week. We'll see. If it lasts into mid-December that would be a little different from what we have seen this year (where -PNA's last 7-10 days then go away).

I'm not going to bet you money, maybe another time, but I will bump this on Dec 14. I don't think you're going to get that snow.

I see +NAO/-PNA
