Still have some time...that was 75 miles more amped and further west with the height field. I like what I see.

I agree and think at the least guidance should hone in and be more consistent with each runs forecast. We have better data now and the first shortwave system will be leaving the field later as well. While O doubt we'll see a significant event NYC south to NJ, I think a moderate event remains in the cards and LI/SNE are in great shape.

Does anyone remember exactly when the models began to catch on to the low being so far northwest with the event in the Great Lakes last week?

I know it's a completely different situation, but maybe, just maybe, we'll see that happen the trend. All I can say is, I'd much rather have the Euro on my side than the GFS.

Heck of a lot better than 6z....at this point places sw of NYC are really out of the game, SNE is going to get hit big time and NYC is on the fence.

The NAM looks very similar to the euro: big hit for Boston, close to a hit for NYC

50-100 mile shift west and most of NJ is in the game.

NAM appears to be a total miss for NYC and a scrape for far eastern SNE. Not sure what model you are looking at.

Use caution, just because the Euro jumped on board remember its only one run and the models have been anything but consistent. Hopefully we get status quo or better with the 12Z Euro run but I wouldn't be suprised if it went OTS again considering that the 00Z ensemble mean was way east of the op. Next two runs are very critical.

I'm really having a difficult time seeing the differences between the 6z and 12z runs when I flip between T+78 at 12z and T+84 at 6z. The deformation zone is a bit better at 12z, but otherwise, nothing to significant to my eyes.

it might just be a coincidence that it LOOKS further west because of the better developed deform zone but I agree except for the low being slightly stronger and further north at the same longitude (maybe 50 miles) not much of a shift in track west, but 500mb looked better earlier on so who knows.

"Look up, my friend." I agree with you as far as the surface depiction goes. However, look aloft. Both the 300mb and 500mb seem to have shifted west, the 500mb vortex seems to have trended more amplified and further west. The 200mb jet streak is certainly more favorable for the 12z than the 6z; a more negative tilt.

Nope, I mean at the surface and 500mb. It doesn't have that weird kink over the Delmarva in the 12z run, which is helping the better deformation zone, but otherwise is basically the same.

From what I've read (not sure who posted it), doesn't the NAM tend to under do precip in the NW quadrant? Or is this just some garbage that I picked up last night that needs to brought the curb now?

It does to an extent, its usually more that its too compacted with the precip fields on the NW side...sometimes this is correct like the 2/6 event last winter....but often it is wrong if you don't have a huge arctic high with dry air in place or major confluence north or NW of the storm.

unless the 12z GFS comes 300 miles west, the 0z euro was probably a blip.

It needs to show some sort of significant movement...last year when the 12Z Euro suddenly came west on the 17th, the 12Z NAM and GFS before it were a big miss, but the ensuing 18Z GFS and then the 00Z quickly became a hit.

What happened, now that the euro shows a big shift west it's all of a sudden not the king anymore? Now it's wrong? Wait at least till the 12z run of the euro is out before downplaying it.

sundog the problem is that as good as the euro is, it sometimes has these "blip" runs we've been talking about where it has one solution for a long time, and then all the sudden has something completely different, only to switch back right after. Could it be onto something? Of course, but until it shows consistency the prudent move is to assume it was a blip.
