The group of years you picked is pretty terrible for the last full three months. Its completely wrong for the jet stream pattern over Asia for three months, and that determines what will happen for the build up of cold air in the Fall for us in the USA from both Russian and Canadian sources. You can already see the issues with it - because Asia is opposite the correspondence of the 'sin wave' so to speak puts the wrong signature over Greenland. My simple blend had it warm in October, yours is cold. The warmth I had over Northern Canada/Alaska is what will matter for the winter, and I showed it very warm for the period shown. You don't, you have the half degree warm / cold muddled crap that prevents any chance of your outlook getting US temps right later on when cold air is sourced from the North.

This is an exercise aimed at seeing if human subjectivity can be removed with an algorithm selecting analogs with a focus on the North American domain. More broadly, can analog development become an objective exercise. I don't know if that's possible right now. 

As noted in the discussion, I don't like one of the three that the algorithm chose (2011-12). I also include one (2024-25) that the algorithm did not choose. I will periodically post updates on this experiment.

If there is merit in the algorithmic approach, one should see 500 mb patterns come more in line with the composite idea  over 1- and, especially 3-month periods. The focus on this set is fall 2025 and winter 2025-26. That there is some similarity at 500 mb for winter 2025-2026 to the ECMWF forecast suggests that there's consensus on the boundary conditions and how the pattern might turn out. 

I don't believe the winter 500 mb idea from the experimental set precludes some intrusions of cold air into the CONUS during the winter, particularly the central U.S.

Nat gas up +11% (with oil down a little) as of this posting. Have there been any updated cold winter forecasts from any of the respected forecasters to anyone's knowledge?

Having trended substantially colder over the weekend, weather forecasts were in the driver’s seat Monday morning as natural gas futures mounted substantial early gains.

This is referring to colder 2 week forecasts, which is typically what NG reacts mainly to. They don’t normally react in a substantial way to updated winter forecasts.

a little surprised by this because it’s more of a strong-storm induced cooler airmass, not canadian-sourced arctic air
