I found this interesting. Someone that actually looks at historical data rather than depending on models.

Don't be surprised if the coming winter ends up becoming particularly brutal. This is not a winter forecast. I will post my thoughts in November when we have more known factors at hand. Even then, seasonal forecasts are only right about 70% of the time. With that said, we do have a good idea on how two big factors will influence the winter and I wanted to share what we are seeing behind the scenes.
The biggest is the El Nino Southern Oscillation. It is likely that this winter will be a neutral season (La Nada), and if it isn't then it would be a very low end La Nina. A neutral season or very weak El Nino or La Nina tends to promote a colder than normal winter for the Great Lakes region. A strong El Nino is typically very warm and dry. A strong La Nina is typically very warm and wet. A neutral season is colder with near normal precipitation assuming all other factors are equal. The other major player is the Polar Vortex. This is more unpredictable especially this far out. However, we are in an easterly QBO (Quasi-biennial Oscillation) phase right now. This has to do with winds near the equator very high in the atmosphere, but it can promote a weak polar vortex when it is in an easterly phase and lead to a colder than normal winter in the eastern 2/3rds of the atmosphere. Odds are the QBO will stay easterly through the winter, but we don't know for sure and there are other factors that can heavily influence the polar vortex that are unknown at the moment. With that said, the very early factors point toward a normal or even colder than normal winter with average to above average snowfall.
Speaking of snowfall, a normal winter would be a rude awakening at this point. We average 37.6" of snow each winter in Toledo. In the past 3 years, we have only had 36.8" combined. We have never recorded a snow total that low on record over 3 consecutive years. I have met a lot of people that tell me this is the new normal with climate change. I strongly disagree, because the data suggests otherwise. Despite the lack of snow the past 3 winters, the long term snowfall trend is consistent since at least the 1950s. While winter temperatures are increasing, winter precipitation is also increasing, and snowfall totals are about the same. In a nutshell, our historic data set suggests the pendulum will swing the other way towards more snow. When it does, it is going to surprise a lot of people. I don't know if the winter of 2025-26 is the season it all flips, but if it does, you will easily be able to trace the warning signs back to the summer of 2025 months before it happened.
The map below shows the temperatures in the previous “La Nada” winters over the last 25 years. The southeast and southwest were near normal temperature wise with the coldest weather compared to normal in the northern plains and Great Lakes.
