It’s only one bad run of the Euro and EPS but they are the models you want on your side for a snow chance... we are getting inside 144 hours which is the Euro bread and butter range. Key for me is the ensemble support, you want better eps support than what we have right now to feel good about this. Still plenty of time for things to change but we took a step back last night with the Euro.

I see the back and forth dance and flip flopping with the models has begun. This is typical. We see this all the time when we have a winter storm threat. Yesterday the Euro was the first to show the storm, while the GFS and GEFS showed nothing, and the last run of the Euro showed less, while the GEFS jumped on board last time and shows a storm. Very rarely do we have a storm show up on the models and stay there the whole way, and very rarely does a storm show up on the models at the same time this far out. The back and forth and flip flopping at this time is a good thing in my opinion. It happens more often than not when we have a legit threat for a winter storm here. It is hard to get a storm here, and it is hard for the models to get a hold of one this far out. Heck, sometimes they do this dance until we get inside 48 hours. As long as at least one of them shows something this far out we still have a threat. Just have to wait and see how things go and how they sort things out now. Sometimes they have to get through all the noise to show what eventually will really happen.

The op GFS was the first one to find the storm, not the euro. The euro found in a full day or so later. Then the GFS IMMEDIATELY backtracked with the next run and said the ULL would be left out west and the NS energy will be too progressive. Then the Euro continued to show a nice solution, with no ULL. Until 12z yesterday, some separation started to occur, and with 00z today was even more.

The euro is clearly trending toward the GFS and they’re actually in more agreement today than they were yesterday.

Just because the euro Op has “something” this run doesn’t mean it will at 12z...the trend is obvious unless this is a big goof by the euro.

We have had big storms show up and stay on the modeling, I don’t think Dec 2018 gave us too much trouble and kept showing up solidly on the means.

But I agree with you about the noise. It could be just too much for the models to hone in on, but it seems they are moving toward a shared solution that leaves the SE out of a nice system.

Bottom line if Euro doesn’t trend better today. That won’t be a good sign. The chances of it getting squashed are high.

I’d rather see that at this point and take my chances instead of a big jump north cause that would be a lock.

I'd like to see some actual consistency with the models for at least two days to consider anything a trend. And even then they could change again. There is plenty of time for more back and forth with what the models show.

Like I said yesterday, consistency and agreement are what's needed and right now both are shaky. That was euro run #3 only 13 or so more to go.

Regarding the 12Z GEFS that I just posted, the main reason I’m giving it a decent chance to come close to verifying for a change is the +AAM that still looks like it is on the way starting around 2/20 (see image below) along with the prediction I made last month for the coldest wx of the winter/2-3 week long cold domination in the SE somewhere between 2/20 and 3/20, which I’m certainly sticking with. A +AAM has a good correlation to a +PNA and El Niño like patterns:

What the heck, time again to post still another weenie CFS map since it fits in with the trend, has been showing up on many runs, and is only 16-20 days out rather than late in the run:

Edit: more 6Z CFS day 16-20 maps:

Ground hog will be wrong imo for the SE at least based on my earlier post with other than some days next week spring being over til further notice. Also, I might as well add some more teles, which look so much better than most of this winter and actually look pretty darn good:

MJO GEFS:

MJO Euro monthly:

AO: sharp dive late month!
1581706782071.png

NAO: drop late month

PNA: can work with this slight +PNA:

Don’t shoot the messenger! You’ve been right from long range so far about late February turning favorable 🙏🏼

I cannot count how many times in the past GaWx has nailed these long range predictions. Either through analogs, or a tele he picks up on during the winter that he interprets as favorable for wintry in the south, he knows his stuff. He is the EF Hutton of the weather board, whenGaWx talks, I listen

Thanks for the nice comments above! Even with the late Feb threat and cold period, I won't claim credit for a correct prediction unless BN dominates for a 2-3 week period between 2/20 and 3/20. But I remain optimistic for sure!

PS: Credit needs to go to Maxar for their valuable guidance, too, especially on AAM that I knew virtually nothing about til 2 months ago.

AO dives over 6 levels and is still positive. I mean, think about that for a second. SMH
