Cmon man give the GFS some love, lol. It was only off by 40 inches in Binghamton and 2 ft in Albany. Such a POS model.- 1,011 replies

I still think it will mix as precip shuts off after intitial burst, then back to some snow later on as low heads east. I don't think anybody in NYC metro sees above 10 inches except maybe Northern Manhattan/Bronx/Yonkers.

I especially wouldn't trust crappy GFS with thermal profiles. I think maybe 3k nam would be best to look at thermals. There will definitely be mixing and/or dry slot NYC metro.

I'm assuming it's similar to it's last few runs where it gives big snows up north to Albany and is warm on the coast just by seeing how tucked the low is.

If you really think it has done a good job with the evolution of this storm to this point then I don't know what to tell ya.

Huh? it's just a bad model and it performed miserably. Euro, CMC, Ukie, all outperformed it. Even Nam and RGEM who were out of their useful range had a better handle on things before GFS.

Yeah ok. Every model picked up on what was happening with the storm for the most part well before the GFS. It caved after 5 days of embarrassing itself.

For 5 days it had the low 100 miles south of all other guidance and it's northern precip field was a joke. It's been a train wreck with this storm until it finally caved earlier today.

You're kidding right? It's been atrocious. 24 hours ago it was giving me 3 inches. It caved to other guidance today and is now on planet earth with the rest of the models. Latest output is now 19 for me.

Not impossible but not likely. I think we get 12-15. Ratios will be 13 or 14:1 also.

Meso's like RGEM and Nam cannot be disregarded at this point but I too would like to see an ever so slight eastward shift.

NWS Albany was talking 14:1 I think by us. I think this map includes ratios.

The most egregious being the GFS. All other models had the low 100 miles north while the GFS was OTL and people kept hugging it. Consistency doesn't mean sh!t when it's obviously wrong. All models IMO can't be trusted beyond 72 hours it seems the GFS is the worst of the lot. Stubborn and stupid. This is the best this country can do? It's embarassing.

Yup. I've been saying it for 5 days. It's garbage with known biases.

And this is why you can't trust the GFS especially when it is on its own. For 5 days it was 100 miles south of practically every other model with the low and then moved it east, and was showing a pathetic and incorrect northern extent of precip. Look at it now. It gives me 18 inches after giving me 2 inches for 5 days. POS.
