Winter 2026-2027. Historic Potential

Looks good to me. It’s looking colder than what models had for 23-24 Nino

Long range models constantly had a 500mb trough over the Mid Atlantic, including the Euro. This held all Summer/Fall then in the Winter the long range Euro weeklies were constantly showing the same pattern, a trough over the Mid Atlantic. It didn't work out - 23-24 was the warmest winter on record for US.

I have enjoyed reading all the thoughts on this thread during the past hour.

I see that J.B. has defaulted to 97-98.   I pray that he is correct.  97-98 averaged +2.20 Nino, the ECMWF is closer to 3.00 for this coming winter.

As most realize, we are in a serious to extreme, drought.  To prevent hardship for many in our society, we need lots of rainfall or melted snow over an extended period of time.

I pray for a repeat of 97 - 98 because it was the wettest winter of any of 9 strong Nino's back to 1950. I received 22.62" of rain and melted snow compared to a normal 8.40" of precip. in DJF.  Regarding snowfall in 97-98, 33 inches was 9 inches above normal for Augusta County.

Regarding NAO or AO for Augusta snowfall ??   The NAO doesn't seem to be really important, but the AO should be firmly negative according to historical observations.  During 97-98 the AO averaged -2.00 and the NAO averaged about -.30".

True.

Gold spun from straw, perhaps.

The thing about a strong El Nino winter is that expectations are always high but reality can sometimes be a disappointment.

72-73 at +2.00 only gave Augusta County 3.0" of snow.  86-87 at +1.60 gave Augusta 52" of snow. 91-92 at +2.30 only gave Augusta 3.3" of snow.  09 - 10 at +1.50 average gave Augusta 63" of snow. The thing about 09-10 is that both the NAO at -2.00 and the AO at -3.50 were strongly negative. I think that was important.

The wait is over. After today, shorter days until late December. 

One thing I'm noticing is, despite chances for AN temps among some models, I'm not seeing any all out furnace runs...not yet at least.

Happy Fathers Day to all the fathers out there.

Looks Modoki, but that's probably a long shot at this point. But it's not alone completely  as Cansips has a more Modoki/central Pacific centered max:

If we can get a +pdo and some semblance of a -amo, we may be in good shape this winter

CanSIPS has a basin wide Nino for the winter months. If that verifies the chances for snow vs mostly rain will largely be determined by the HL pattern. As currently advertised the h5 look(+PNA/-EPO/ possibly -AO/NAO should bring some colder air southward at times to combine with a pronounced STJ and some favorable storm tracks. All speculation at this juncture ofc. I will 100% roll with that idea. Anything but a strong East-based event.

Cansips really shifts the El Nino west. Looks dominant in 3.4. Not sure that's going to happen with the current orientation of the subsurface, and Nino 1+2 currently being +2.8c vs Nino 3.4 +1.3c.  It looks like it actually cools the far eastern Nino regions between now and the Winter. Don't think that's going to happen with the ECMWF Seasonal forecasting the strongest El Nino on record. 

Also we haven't seen that "easy +PNA" over a long term period in the Pacific for a very long time.

Hey Ji, did you do this graphic?  :)

Okay Ji, excellent graphic. But Texas does not want all that cold. Stop the cold and snow at Dallas. Above normal rain and mild south of there,

With the projected strength of this Niño, anything on our side is encouraging at this point!

I think that's a fallacy. There aren't enough examples and NAO/AO has been skewed more positive on Super events (which is a more random point). You have to go back to the physical mechanics of El Nino - Weak vs Moderate vs Strong vs Super is the same. Difference of course being whether it's east or west based, but I think if it was a +3.5c Nino 4-based El Nino people would be saying blowtorch :wacko:

Having CanSIPS and JMA on our side at this point is actually encouraging no matter what ECMWF and Chuck say :P

I don't think it's impossible to have -EPO during El Nino's. Historical analogs are probably too +EPO (further north in latitude is more of a "random point" than like the PNA and NPH). If you look at the reverse of 1895-1948 La Nina's, it's very -EPO/WPO.
