ECMWF ensemble mean trakcs the storm maybe just a hair inside the BM...mid-levels are just a touch warmer than the OP run, they probably bring sleet back up to Kevin's area in N CT or at least a HFD-PVD-GHG line before collapsing back SE.

Sounds an awful lot like Xmas '02...which was an absolute sleet fest here. :axe:

06z NAM looks like a perfect thread the needle weenie run for I-95 M.A. all the way up into SNE for trying to get mostly snow. It actually is a bit on the light side for SNE but good for south of here.

That's an amazing run down there... Earthlight needs more snow... it's been too long since his 30 inch storm. hehe.

But seriously, it's a move in the right direction up here.

Nice shift north on the 6Z NAM. I'd be surprised if it doesn't trend further.

Not sure why the temps depicted are so warm at the surface, but the fact that the 40F line is pegged down by ACK is fine with me. Seems like a slightly cooler profile to me. Maybe winds are a hair more from the ne as depicted.

Temps at 925mb are colder too. The 925mb circulation seems a tad se of 12z, so perhaps the mid level lows are tighter in with the surface low.

I'd expect the NAM to steadily move in the direction of the Euro at this point. This hasn't been a storm where the NAM led the way on where these solutions were going. In the Jan 12th storm it latched onto the idea of a small compact bomb that would track closer than globals were saying and didn't let go of it and others trended toward it. This time, its been all over the map with monster swings.

This is where you probably just hold close to the ensemble mean for now...as its been very close to the steady Euro.

Odd solution on the 6Z NAM with a hard stage right.... barely a flake north of MA-NH border

Agreed, EURO has given most consistent solutions in past 2 days... and it appears other models (GGEM, GFS, NAM) jumping around but trending towards it, with a track 30 miles on either side of the BM

Odd solution on the 6Z ETA with a hard stage right.... barely a flake north of MA-NH border

Agreed, EURO has given most consistent solutions in past 2 days... and it appears other models (GGEM, GFS, ETA) jumping around but trending towards it, with a track 30 miles on either side of the BM

You mean the 6z NAM? I think the ETA is now run as a member of the SREFs at 3/9/15/21z. A lot of those hi-res models are showing a sharp cuttoff to the precip and a turn more eastward with the storm track

Interestingly the RGEM doesn't support the GGEM at all.. the 6z RGEM is 1006mb strung out in southern AL/GA at 48hrs.. while the 00z GGEM is 999mb in far northern GA at 60 hours (6hrs later). Even accounting for the time stamp difference, the RGEM is much farther south, weaker, strong out (sort of that two low look).

I think it's possible that the finer resolution models are picking up on some leading PVA that disrupts the storm formation and causes it to get strung out almost into two lows. The GGEM is pretty coarse if I remember so may not be picking up on this process as well.

Well....messenger, Ray, Bostonwinter08 almost had me convinced to stay up for the Euro...glad I didn't as I might not have slept...

As I mentioned just before going to bed, I expect it to trend slightly E based on the uncle and it did just that. Now we have pretty good consensus on a snowstorm this week. Can't ask for more than that...

Well it's time..I think we will see some amounts near and probably over 20 inches in SNE

If the Euro can hold serve for the most part form here on out, then yes, in the CCB band, there will probably be someone that can break 20"....obviously an area that stays all snow

What does your gut tell you?? Does the sleet make it here?

Yes.

My gut tells me it will try and be a little NW of current ensemble mean of most guidance right now. I might sleet for a time too, not sure. But its probably going to be a very juicy system with a ton of convection coming out of the gulf, so it might try and hug the coast a bit longer before turning right.

Hopefully despite that, it stays cold enough for all snow. The guidance has been keeping it a bit colder in the mid-levels for longer.
