It's the new gfs so I don't trust it. Also, I've seen 18z runs this year really try to show weenie solutions only to completely eat itself one run later. Call me skeptical.

Probably best to be skeptical in a thread the needle situation at day 5 haha.

And yeah I keep forgetting it's the new GFS. I wasn't impressed with its performance as the Para GFS so far this winter.

Did anyone even do verification score for it before it was official/love?

 

Yes, they hindcasted like 3 years and it scored better than the regular GFS consistently. Now, we will see how it handles east coast cyclogenesis...the old GFS was desperately terrible on that front.

 I don't think it was running on all parameters on the super computer when it was the Para

Closer to the Euro solution from 12z, though maybe not quite as far west. That solution will be sure to grind up the clipper as the MLK system sits and spins north of Maine acting as a shredder.

Beyond the potential to grind up the mid week clipper is there any other collateral damage that this system can inflict on our improving chances of snow events?

Clipper s/w was vigorous on this GFS run that was able to fight some of the confluence and still produce like an inch or two for SNE. Pretty impressive givne the hideous location of the MLK event stalling like that.

This is eerily similar to January 2005 evolution. The pattern flipped and we spent the first week chasing crap. Then the NAO and PNA worked in tandem and we went to the promised land. Kind of an archambault signal during the 1/25-2/2 time frame to me.

It can actually help us some...it assaults the Greenland vortex region. Part of the NAO drop we see on the progs is the transient ridge downstream of that system. Anything to help weaken the zombie vortex could help....as it may try and set up a more permanent -NAO after the 25th.

 

I think shredding the clipper is the only real negative.

There is definitely potential for an Archambault system in there...esp with the uncertainty (but seemingly tending negative) of the NAO phase now.

Thanks Will, that's actually very informative from a learning perspective.

This is really the first storm in a while modeled to sit in the GOM so I can see what you are saying about affecting the Greenland region.

Yea, with some luck.....similar evolution wouldn't shock me, as that season was not a bad analog going in.

Just tough to shake the "boy who cried wolf" syndrome, and maintain some semblance of dispassion.

Clipper s/w was vigorous on this GFS run...enough so that was able to fight some of the confluence and still produce like an inch or two for SNE. Pretty impressive givne the hideous location of the MLK event stalling like that.

 

I've seen worse positions, maybe its different for me down here but I think that vortex is far enough north for something to happen with the clipper.

This GFS run has a large signal for a Miller A.... ridiculous deepening of 53mb in 27 hrs from hrs 207 to 234

 

The spread for that thing is still massive...you can argue everything from out to sea to a raging Chicago blizzard...there is definitely northern energy which is always trouble and could cause it to phase too early.  The NavGEM is hinting at that at the end of its run, right now the Euro and GFS are definitely siding on the out to sea end of the idea.
