The return of winter pattern disco


Damage In Tolland

Recommended Posts

DGEX (from the 84 hour Bob posted) is going to be divine in the 96 and beyond range. As Scott says...strap in and wait. We should have much better consensus in 48 hours. Expecting a model burying you 5-6 days out to verify is asking alot..but we all do it.

He posted the Eta though...not the NAM. The 84hr NAM looks interesting too though.

exactly. that is the big difference between it and the other models. It may be that it is right and leading the way. But at least according to Tip the teleconnections suggest digging. So now I think we need to start to look for closer in signs as to whether factors are setting up to suggest more digging or less digging (or no digging). What data can we start to see that will help us track that?

alright so in this vein, if the Euro is the only model not digging the PV much or fast enough, then lets see what the next runs of the other models do:

18Z NAM is digging yes?

next up is 18Z GFS

I like to have one thing to focus on in the upcoming runs.

1 point being missed, the Euro generally has the best 5h verification scores even if it's botched the surface a few times. Disconcerting but I'm not a card carrying member of the Euro fan club so NBD.

NAM does look nice at hr 84...for whatever that's worth.

Yeah that looks like it would be major. SREF agrees with it too though obviously a little more dulled down and smoothed...but its def. dropping that bottom half of the lobe pretty far south.

What did you think of the ec ensembles?

Well the spaghetti plots looked like the OP was the slowest. The mean looked like a mess with a storm trying to redevelop back toward the BM, but then the center being way east...but a ton of spread west. It basically looked like there was a ton of uncertainty...at least to me.

I'm betting against the 12z EURO......all my antagonists who taunt me chants of "negativea" can take that, sit on it and rotate.

I call BS on the EURO.

I agree. Let's face it, it is an outlier and while scoring well on NHEM H5, it is unlike any other guidance.

It looked like it would make a run for the BM at hr 108 with a fairly large spread, but then tightened up and jumped ene. That's why I was saying it was sort of a head scratcher. But look at 500mb. It does not want to do much with the trough.

It looks like some members want to bring it south of sne, but I was surprised it didn't look at least similar to the Canadian.

Amazingly the Euro has had the least continuity over the past 36h of any OP model. The ensemble mean can only tell us so much sometimes...when you look at the spaghetti plots at 5h by 108-120h, you can see how the OP has become the outlier. The spread gives us a level of confidence in that ensemble mean (I know you know this, but just saying for those who are learning).

I certainly wouldn't trust any solution right now. The GFS ensemble had a lot of spread too. Some solutions gave us a HECS and others gave us very little snow at all.

Which Euro?

Here's Euro h5

0z Euro digs to the mid atlantic

12z barely any digging til way late

Depends on which euro you like for best verification cause one of those two is going to fail horribly.

Definitely agree with that. I guess the one thing that is nice to see, is that all models at least give something around D5, and there seems to be some events shaping up over the next 2+ weeks.
