January 2026 Medium/Long Range Discussion

Def a good pattern for SWFE shaping up for end of January.  Hopefully we can cash in a big qpf one that hammers the whole forum.

I spy a little -PNA the last week of Jan. I hope models are still biased too low on PNA

I see it briefly at 264hr. The 360hr 0z EPS has a favorable look

Thats what I’m hoping for, a temporary transient -pna as an incoming wave undercuts across the sw towards here. 

[bncho]

That's a massive signal considering it's 330 hours out.

It shifted south from 0z, so quit complaining.

That is like telling water to be dry.

Just saw the Euro weeklies, good trends up until mid-February. Think we may be able to extend our window until then if it holds!

[Heisy]

The day 5-6 event is growing some legs

there’s a couple decent members in there. Depends on the angle of the shortwave. Wouldn’t take much for this to get juicier

Yeah, since early Dec this season has been a slow bleed through time even though not “torchy”. Hoping we cash in during our most favorable climo.

Real nice -AO showing up at the end of 6z GFS ensembles

Correlation with temps (default is positive so -ao is opposite)

It's been a Nina STJ.. too bad because we are having our 2nd below average temp Winter in a row. Last -PDO decadal cycle was also cold and dry.

It seems like the cold hasn't been the issue at all this year. No real torch. We just don't do coastal storms anymore for some reason?

I do like the timeframe after Jan 25. Not sure about the Jan 22-25 window, any storm there looks like it wants to cut. But hope we can get a follow up after.
