January 2026 Medium/Long Range Discussion

[SomeguyfromTakomaPark]

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

Got to get something done soon. Damn sun angle season is right around the corner.

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. 

[Stormchaserchuck1]

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.

9z Srefs like the idea of rain ending as snow too.

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?

Yeah, the lack of STJ in a nina.

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.

That can you just kicked is going to hit JI in the face lol

This way out there and low skill (unlike the precision of the Euro ), but the Cfs2 has been hammering for weeks a well AN precip March as reflected in the attached map. Looks Niño to me. But IF correct and we can get it falling at the start of the month with the most favorable temps, we might have a shot at some measurable March snows which have disappeared since 2018. I know, I know,...snows in general have disappeared as well, but after a decent string of March snows starting in 2014, they have generally been MIA since 2018; arguably, 2019 did have an event that was small at all airports and IAD had a few inches in 2022, but they were not area wide.

I've been consistently saying that the tropical forcing in MJO 8-1-2 and death of La Nina will help with a more canonical Nino response into February and March.

12z ICON has a worse outcome than the 00z ICON for our area on Sunday but the system looks a lot more like an actual storm now. Imagine it trended better at h5 but it's the ICON so not that interested in digging in lol
