Whats Ur Gut say

Cumberland crippler

Lights out Lincoln

Guts says the banana and OJ I had this morning were not enough. Honestly IDK. Tricky Dicky situation as all phase capture storms are. If it does phase and slow near the coast its Katy bar the door. Full moon goons are the best.  Green flag GEFS have not changed in days with -Sds, Red Flag Euro Op and a bunch of EPS members, buckle up

The 00z suite still has the bulk (even more than 12z yesterday) of the variance explained by a north/south dipole off the New England coast. So much of the ensemble differences are between north/south positioning not east/west or strength.

The upper air pattern that supports that is somewhat convoluted, but does show that there was some sensitivity to initialization. Namely the wave dropping down the West Coast. Mean modeled heights were lower than observed (opposite of the sensitivity pattern) so some corrections SE may happen today. But the northern stream modeled heights are actually higher than observed, so maybe not. It's not a strong pattern, so strong moves one way or another shouldn't be expected.

Thanks.  Convoluted to say the least than.  12z suite will definitely give some answers though.

Rolling it forward to the 12z raobs, the 00z Euro is actually closest to observed. 

Euro sensitivity matches the GEFS too (the majority is explained by a north/south positioning difference). I think we really want to see heights falling below forecast just downstream of the wave later today, with higher heights through the Upper Midwest/Great Lakes late today into tomorrow. That's a pattern that seems to produce what the weenies want to see.

I'm going to get Dec 92'ed again, aren't I?

We will know soon enough, I haven't had a real good feeling for this, Just don't like the way the whole precip field  and H5 low gets squeezed out under the block in a NW-SE trajectory, That is why i want to see the primary get as far north and west before that all takes place.

At this point are we in or out of the game up this way?  Do we need a few more ticks north to get into the good stuff?

We definitely need several more ticks to get in on anything worthwhile. It could really be a sharp northerly cutoff too. EEN to PSM is probably closer enough to still have some hope, but north of that needs help.

Yeah, I was thinking we will see some sort of compromise in between the OP GFS/EUro runs at 12z today.

The fuzzy clustering has two good groups (out of 5) for New England (but about half the members because a lot are clustered around the ensemble mean which is good). 

What those two groups have in common are faster and stronger primary low development, and deeper/faster 500 mb trough development with the northern stream and weaker NAO ridging.

The faster stronger development is key, That's what we want to see, The sooner the better.
