We are following the trend on a group of computer models. If only one of them said this, once, then you would be correct to throw it away. As it is, several models have shown this for a substantial period of time.

consistency and agreement with other models is key in any event iMO

Models love to extend storm duration.

I mean every single model is showing the same thing except the GFS. Ensembles are as well. I mean there's really not much more you could ask for?

true and the GFS ensembles disagree with its OP

I consider the GFS solution unlikely  as of now because of little support from other model guidance and the history of this model showing extreme solutions at this range in the past

I'm happy it's the GFS showing the miss and not the CMC, ECMWF, or UK. But big snowstorms are uncommon - everything has to go right and usually doesn't. So it's reasonable to be on guard for what might go wrong. Any signs of trending towards the GFS should be concerning if you want a big snow event.

We’re 5 days out so you really think what you’re seeing now holds true on Sunday?

Big potential when all the models show basically the same thing and the pattern supports it.

Not a major system but wouldn’t matter given how cold the airmass is.   We could see a foot even with .75 QPF.

Yeah it was a sloppy phase and we still get a foot.

[Franklin0529]

The Euro is about a foot in the city more south. Onto happy hr

Yup, not a clean phase. It trended towards the GFS with regards to handling the SW energy.

[eduggs]

The 12z ECMWF is a step back from 6z and 0z. The phase is not as clean. It's still a great storm as depicted, just not as favorable as the past 2 runs.

Hopefully a blip and not a trend towards burying that energy.

What was 0Z and 6z euro?  I thought it  barely showed snow past the mason dixon.
