As I mentioned in the other post; you can see what I mean on the snow maps for the gfs. The little regeneration and lingering snow late bumps from like you down to like Foxboro over a foot.

Yea, there is a shot for the transfer coupled with the easterly fetch to do that, but I wasn't going there on Sunday, when I issued that first map.

Why do you broach that issue with me like every day? lol Its pretty robust, I get it....I don't rip and read it. Its the best algorithm for determining precip type, but its still just a tool. Also, its only as good as the data that the model is spitting out, so if the modeled QPF is overdone, so will its snow output. I'll still sell widespread amounts over a foot.

Just for clarification purposes. You said Kuchera was good for banding what is Narcan best at. You posted NAM can you post the globals as well?

NARCAN is good with thermals away from the immediate coast, and banding....it can be too stingy near the ocean. If it is still that robust come Thursday, I will def consider it more strongly.

meh.. has to be right as the sun is setting with the massive last February sun angle scorching everything.. unless its like 40 to 20 in 30 min

It was around dusk here. I mean it would freeze stuff up quick here because that’s basically the cstl front coming through after getting into low 30s with what probably will be some slushy mess too.

ya just looked that's extremely impressive for you guys. here it's more gradual but would still turn everything to concrete.

Very nice looking bent back WF in the mid-levels on these runs. That is indicative of a very strong thump. Same sig as 2/5/14....that's how you can manage 10-12" of dense snow from these. You want to be just north of that mid-level WF where it's slowing down to prolong the enhancement.

Caveat being that big deform bands are poorly modeled, so even the NARCAN maps will not fully capture it....again, only as good as the model output.

Snow maps are overdone.

I don’t really know how to read those super well but it looks like to my untrained eye that everything is below freezing. I’m not so sure it is overdone, that reach around signal is on all guidance. Features like that wouldnt the mesoscale models be able to pick up on better? If anything, I would think it’s being underdone by the global models.

Possibly. I’ll be honest with you though. As long as the morning is crappy enough to get me a day off, I could care less what happens after that 

Oh yea. Not arguing against that. I'm not going anywhere Friday. I'm only debating the big clown map totals which are counting the backend reach around as some high ratio fluff bomb.

Yeah big time.

Yeah I remember being initially skeptical of 12"+ amounts in 2/5/14 but we were discussing the bent back WF and how it was just going nuts on the north side of it...and then it verified that morning. We were getting like 2-3" per hour rates even with snow growth not that great. Like a quasi-stationary band near the pike in that and maybe 10-20 miles either side. The QPF was big....BOS and ORH ASOS both had over an inch of QPF in that.

Not saying we can lock that in yet on this one, but if the model guidance doesn't change significantly, then it's going to happen somewhere in a 20-30 mile wide zone.
