GEFS still has this.. Maybe it's a bias because of how the last 7 years have gone in February? It's had the pattern at Day 13-15 for the last 7 days, and it doesn't seem to stick as the times get closer

You can see the differences between the two models in the Pacific

The gefs is trending towards the EPS and it’s only a few days behind getting to the same place even if it’s right.  At least with respect to the day 15 pattern.

The strongest signal for a MA winter storm has been around the 12th across ens guidance, and that went up a notch on the 0z runs.
Surface depiction on the EPS. GEFS looks similar.

10 days out. Hopefully the trend is a little colder and souther, and not the other direction.

A lot can change in 10 days but the data is as snowy as I’ve seen on the ensembles in years especially in February

Last year at this time…the great looks we had in the ensembles were starting to fade. This year the opposite so far

The AI establishes the monster block by day 10 which is why the more suppressed solutions in the long range.  

Yeah this look is probably a little too soon. Hopefully we get there. That is a pretty nice track though.

@CAPE I felt pretty strongly we would get one more bite at the -AO apple this season but now I’m almost ready to call go time. It’s supported by everything. Analogs. Mjo progression. Recent AO cycle behavior. Scandinavian ridge. Monster poleward EPO ridge. And now the SPV is getting obliterated and split in one of the more sudden strat developments i can remember.

I guess the QBO phase is the one element that doesnt align, but the amount of impact it actually has always seemed a little nebulous to me.

The last couple times we expected it to help it didn’t seem to do squatola. We already had one period of blocking despite the “hostile” QBO
