Mid to long range discussion- 2025

Looks like the cold is going to center in the rockies/northwest first and we have a big ridge until the end of the month

Yep. MJO taking control of the Bus. Blocking may mitigate the Heat in the East by squashing the SER. Hopefully that western trough doesn't dig too deep and help the SER hook up with the -NAO. Models are not showing that but after seeing that happen the last several Years it makes it a possibility.

Exactly. That's my main concern and it's incredibly hard to get rid of

Long range continues to look generally warm on ops and ensembles. When does it flip?

Doesn’t need to flip until December, at the earliest. No sense wasting all the good teleconnections in November, when most of us can’t get snow anyway, despite the upper air patterns.

Agreed.  I'll take it in late December/all of January.

Honestly a transition the first of December would be best climatologically speaking.

Eww

[wncsnow]

I agree that a perfect pattern now would likely mean no snow outside the mountains but patterns repeat themselves and the one the next few weeks looks very Nina ish

Interesting development in the North Atlantic. SST'S becoming favorable for a -NAO this Winter.

Worried about SER this winter. I’ve seen this tune before it gets going and PNA continues to screw us until a one week post frontal cold snap in January especially in a La Niña year. This setup is tough to burn in the SE especially when it’s already rearing its head. Could flip, but color me concerned with PNA trending negative. At least it’s mid November not mid December heading into a screwball pattern but winters where the SER gets going and Pacific trends to hell tend to have repeat performances through the season and being a Nina year It doesn’t feel great seeing this pattern show up
