Guys, it is all the timing and strength of the southern vort. On the GFS it is a little stronger overall, therefore it rounds the bend in Texas more as it 'feels' the influence of the northern branch. It is also a little bit quicker, therefore the trough captures the vort as oppose to squashing it, as happens on the European.

The set ups overall are actually quite similar, it's just small scale differences are making huge tangible weather differences at this time between the models.

So the major difference is their handling of the pacific shortwave, which won't be onshore for another 36-48 hours. So we could conceivably be in the dark until then, I suppose?

In addition, the Euro is dropping the northern stream low/trough into the upper midwest faster and farther south, crushing our wave...but yeah, small differences here have a huge impact.

Sow hat do you do when those small differences make the outcome so different? Just wait until one starts caving to the other?

Somebody said that, but that was not what Bastardi actually said at all. He said that his concern was growing for the first accumulating snow of the season from DC to New York City Sunday night into Monday. This of course was referring to this storm.

JB also said yesterdsy he thought this may be the storm to get all started but did not elaborate too much

Yes! Yes! Yes! Exactly. Why worry about the details now is my question

Isn't the UKMET the model that handles Southern energy well along with potential phasing?

 

Has anyone been able to get a look with the interaction on it?  Maybe that is the model to be focusing on this time around.

 

I've been leaning in the direction of the UKMET being a more likely outcome, but who knows. EURO (or GFS) could very well be right.

 

I remember there was a winterstorm either February 2014 or February 2015 one where around this same range the EURO started following in UKMET's lead, however I've seen the vice versa happen too. I feel a little relieved that the 12z UKMET stayed steady as she goes, had it gone more south/suppressed like the EURO I would be a lot more concerned.

 

EDIT: FWIW, I believe 72 hrs and under is UKMET's wheelhouse when it comes to situations like this.

I see some say that the EURO is no longer "King". When did this happen or is it just because it doesn't show what all of us wants? Serious question.

I would say the separation between the GFS and the EURO isn't what it used to be but the EURO is still superior.  I will be utterly shocked to see the GFS right after seeing what the EURO just showed.  I've been on these forums since 2004 and have seen this situation too many times.  The GFS will likely cave and we will be left high and dry.  I hope I'm wrong.

European is still the best model for the medium range. However, that doesn't mean it will win every single battle every single time. It just wins most of them. Haha

Unfortunately I have to agree with you.

That never happened. Euro is still verifying better than the para GFS.

I have to say it is intriguing to see them so far apart this close (relatively) to the storm.  I really am excited to see how it turns out.  It reminds me of a college football game where a huge underdog gets up on a national powerhouse early.  Then the second half comes and that 14-0 lead goes to 55-14 deficit.  I have a feeling that's how its going to be.

I know the Euro used to have the tendency to hold the s/w in the Southwest too long. Anyone know if that is still the case? If so I think that is one of the issues with the Euro.... the s/w moves slower allowing the energy diving in the from the north to press to far south before the s/w is ejected east. This causes the s/w to be suppressed and not able to round the corner and bomb out.

The NAM being so flat continues to lead me to believe the GFS is wrong for now. The NAM is rarely flat at 84 hours vs the GFS

Made a Facebook post with 3 different time stamps btwn the 12z runs of the EURO And GFS today.  Its a long post, but I won't charge ya...LOL   I actually think the GFS could *dare I say* be a little better right now with this...Why?...well, its a progressive model, and we are def. in a progressive flow, EURO may be holding on that energy a bit long from kicking it out.  Honestly, if the DOC would kick that energy out a bit quicker...the EURO would likely** have a different solution.

Anyone want to venture a guess on what the EPS is going to show?  I'm thinking it will be similar to the UKMET. Flatter and south of the GFS but not taking a side trip to Cuba.

 

I'd say south of the GFS, and the GFS will make the south trend in the next few runs. Maybe we can meet in the middle and get token flakes.

 

EDIT: typo

There is no way the Euro ensembles will be south of the Op, it's virtually impossible based on what the Op run does to the shortwave. They may not be a whole lot north of it though

Yea 9 times out of 10 NAM is amps these up into a superstorms. EPS is running so if it shows the same thing it's going to be hard to take the GFS too serious...but given climo and the storm just before it, it kind of makes me think the GFS may be on to something. I just have a hard time buying the big suppression scenario. Last week the Euro showed the same thing while the GFS was hitting the brakes with the big arctic push.
