Just a random shower thought:
This whole vort mess that's tangled up and been a pain for models.... is there a road where some of this mess turns into a 50/50 and suppresses a wave past.... let's say 200 hours or so?
I prefer 8->1/2/3 for the MJO, but's just me. I think tropical forcing has the best influence when it goes through 8 and makes a full tour through 1/2/3. I don't think we've seen it do that in a looonngg time.
Looks to me like it is about to blow its load in the west Pac and crash again.
The thing that is particularly frustrating about this weekend, is that there was a run (12z Friday, 1/9, I think) where all 3 globals showed a pretty similar system. If it had just been one model, meh.... but all three?
Speculation post:
If patterns run in cycles, it's been almost exactly 60 days since we had an anomalous shortwave dropdown over the southern Apps and drop some early season snowfall.

Overall NA pattern isn't quite the same, but thus the:

Would be interesting if we got another rerun of this in early March.
But let's also be fair to the GFS, the Euro (on left) also has some weird tropical critter in Pac, but the shortwave mess just ins't oriented in a way to draw from it.
The Euro still has substantial differences from the GFS
I tried to get he loops as close as I could time stamp wise, but it still seems they are out of sync after a few frames.
At least the 6z Euro has a massive clipper dropping in late in its run
Overnight ensembles still have both windows. I'm using the charts for TRI since both systems have looked better for eastern areas:
I was just thinking that we are entering the period where models sometimes lose systems or change them in some way only to come back 72 hours out or so.
Something to do with wonky stakeouts data sometimes in the polar/ N. pac regions maybe?
I also want to add that I’m sorry for what your going through Powell
Does anyone know how to access ensemble H5 vort panels? Tomer Burg used to have that one Polarwx (I think), but can't find those particular panels any longer.
Trend on the EPS is for more vorticity in the base of the trough:
Would should be bale to have the EPS panels to go along with the GFS member panels covering the event by 18 or 0z tonight.
