Pipeline filled with all kinds of goodies. 

Snow is serious business, NOT!

I have to go back to school. Way off my game of years ago. Life kind of got in the way. Word choice and learn to chill. Its a friggin forum.

Just being in the game is a bonus. Just the threat of double digit amounts ftw.

I can't even buy a flake!

It will not go more north, where is the evidence. Gefs were se of the op... though precip was more nw.

My whole thing is I feel like I'm acting in double-standard if I continue to condone bigger snow amounts... 

My biggest contention was the data assimilation issue but that seems atoned for now more completely and ... much to chagrins it really hasn't mattered to the GFS and in fact, the other models are trying to collapse toward it -

That's not refutable... Having said that, the only thing that holds out for me is that the wind max at 500 mb is running right up and over the edge of that polar/arctic air mass vertical slope and that's likely to draw a pretty significant up glide flow of air into it, because the restoring mass cannot come from the cold side as easily - path of least resistance... warm/theta-e air climbs the slope and that's pretty much why you see the deep navy blue band in the models that have more in the way of impact - I mean there's a logic to those solutions that I think the GFS could be missing here...

As far as the other guidance collapsing ..that can be explained by the dampening of the over all wave ... causing a weaker low which would mean S track...fine as a correction considering the dampening motif is sort of late to the part the last day .. day and half of runs.  Be that as it may, all models including the GFS run a 70 kt 500 mb jet core right over the polar dome and that simply has to cause isentropic lift and a snow burst I think -

What a cluster f!!!!!     god damn I'll be glad when this headache over and we "get to" start worrying about this one ...

You cannot pick and choose ensemble members, there is a reason it is called a MEAN.

Median would be more accurate.  That’s why the eps mean is less skewed by members.  Eps has 51 members vs 15 for gfs.  So eps mean can’t be tugged as hard by one outlandish member in any direction

Skewed mean. Couple rouge way se members while everything else is nw of it.

It's a stretched low as shown on all the OP runs, so those ones just have the "lowest" low already out east. But I'm sure those members are elongated/double barrel

We are being invaded in our thread by new yorkers.

Well when I was living in Des Moines, I needed to interact with the Great Lakes board for relevant interaction. even tho I am closer to the plains and that board technically was where I belonged, it just didn’t work that way hmm

This analog was circulating yesterday. Reality will look something much more like this.

Where the gradient really sets up is difficult to know, but my best guess is right around I-90.

Shift this roughly 50 miles north...

Harvey has me in 2-6”. 

I’ll take pics of my overcast.

It’s all good. I’ve weighted the gfs 30% percent so I’m obv not discounting it but some are putting their weenies on the line on the only piece practically missing our region while negating that it’s ticked nw past several runs. GL with that.

If you can bring reasonable analysis i don't care who comes in and post, But they did sub forums years back for a reason....................:)

I’m rated the FV3 a 0%. It’s not factored

There’s obviously a huge reason yes.... which is why I think it’s weird that it turns out needing to mix like it does. As in, I don’t think there is much solution and it just rolls that way. I feel like maybe back then, and maybe it’s still this way, the plains states board was too huge of an area and Included places like New Mexico and was sparsely used?
