LakePaste25 Posted 2 hours ago Share Posted 2 hours ago The Nina is still there. But this indo-pacific warm pool analysis is intriguing to me. Compared to this time in 2023, the warm pool is expanded much further east. Not quite Feb 2015 levels, but it’s close. If we do regress back to a -PNA, I could see the cold dumping into the mountain west or the high plains. I don’t think it’ll be as far west as 2023. If you factor in the blocking that keeps showing up, it might make things interesting. Link to comment Share on other sites More sharing options...

It's still a bit west of 2015 IMHO...it does look like we may finally be seeing a light at the end of the tunnel, but not enough for this season IMHO. Next year could be great. 5 Link to comment Share on other sites More sharing options...

The blocking will also help if it persists. 1 Link to comment Share on other sites More sharing options...

The deep cold and persistent snowpack has been nice, but I also wouldn’t mind getting back in on the action here on the I-90 great lakes corridor. We’ll see how it goes.

schoeppeya Posted 1 hour ago Share Posted 1 hour ago Pretty incredible PV split the GFS is trying to show: Link to comment Share on other sites More sharing options...
BlizzardWx Posted 1 hour ago Share Posted 1 hour ago Interesting on some guidance, like last nights ECMWF, how quickly the mid level heights across higher latitudes increase after the PV split. Could be coincidence but I hope we can get this going in February rather than waiting till March to see impacts. Link to comment Share on other sites More sharing options...

That's fair, but other ensemble guidance is mostly headed that way too. Will it verify? That is another story but in my mind you usually see hints showing up before it happens, so I am at least glad to see it starting to show up. 1 Link to comment Share on other sites More sharing options...

Oh...I misunderstood your post...I thought you were saying heights in the mid latitudes. Yes, since we are already in deep -NAO/-AO, there should be much of a lag. I mentioned that in my update on Wednesday. My bad...agree. Link to comment Share on other sites More sharing options...
40/70 Benchmark Posted 46 minutes ago Author Share Posted 46 minutes ago Last fall, I assumed that the strong PV accompanying the +TNH would be more coupled with the troposphere, so I thought we would have +NAO, that is why I originally forecast the blocking to redevelop for early March. I missed the late January -NAO accompanying the +TNH, which is why it was colder than even I had thought. 1 Link to comment Share on other sites More sharing options...
SnowGoose69 Posted 2 minutes ago Share Posted 2 minutes ago Indications the QBO may be more E next winter, if that happens and the El Nino is over 1.5 may not be as good as we had been hoping. Might be glad in the future we did well this winter. Link to comment Share on other sites More sharing options...
