Well I wouldn't bet against King Euro, so early congrats ORD/DVN south and east, especially LAF.  The Euro is not always right, but it wasn't far off last event, and its wetness proved closer to correct than many models, the fact that it's a drier model in general this time around is a red flag to not expect as much.

yep, weaker ULL on Euro causing further south track. NAM/GFS had H5 low at 72hr near 532dm, Euro has it at 540dm.

It's all about the strength of the ULL. Further south makes sense if it's weaker. But maybe all the energy hasn't been sampled yet:

Nonetheless, -37 at H5 is already a pretty strong wave. Pretty much American vs. foreign guidance tonight.

Based on this i would say the 00z runs missed a bit of it. 4hrs ago ( 02z ) it was still pretty much off shore.

Agreed, so I'd say we have to wait til the 12z cycle for a clearer picture on this this. Still some pretty big differences on the guidance tonight. Hopefully tomorrow answers whether it's a bigger show for I-80 and north or I-80 and south. Maybe we'll start to see some trends with the 06z runs though.

Yeah the 06z may be a good starting point for sure. That image i posted is valid 06z so yeah i think they may have a bit of a clearer picture and if not the 12z for sure.

 

This system sorta reminds me of the Feb ( 9-10th i think? ) 2010 storm which brought a massive dumping to the DC/Baltimore/Philly region and even a nice dumping out this way in the GL/MW..

Agree with both of you and you can tell by looping WV it wasn't fully or even half sampled at 0z.

 

I should be up for the 6z NAM.

from NARR regarding the Feb 8-10th 2010 storm that Harry mentioned..it dropped around 5" here but over a foot at ORD due to lake enhancement/lake effect.

Dropped a foot here as well. Only storm i know of to do that AND dump massive amounts in the Mid Atlantic. Usually if this area gets hit like that  then New England gets it if anyone along the coast. Like this though that as well had a -NAO.

The GFS ensembles are similar to the op but a bit more spread out with the QPF toward the South, I would disagree with the lack of a strong Southern cutoff as this will probably have one. Beyond that they like the op are much further North compared to the 18z and 12z runs with respect to the Northern edge of the precipitation.

6z NAM coming even further north. Talk about a diffence between it and the 0z Euro.

Still think there's a limit to how north, unless the block is weaker than it's been modeled, though there is good ensemble support for keeping it strong through the time of the event.
