January 4th Snowstorm: 1st Call Snow Map
Here is a stab at a snow map with this very tough and complex system. I will issue a final map tomorrow. At the moment, it seems like the storm will have to battle dry air and subsidence which is why the cut-off's are as dramatic as they are. Can't win them all but let's see what tomorrow brings.

This (Franks map) actually is in line with what I was thinking this morning. After all sorts of ups and downs today I feel this brings me back to where I started the day in expectations. Maybe sometimes things simply are what they appear to be.

Re: January 4th Snowstorm: 1st Call Snow Map
Great map, Frank!! It definitely represents consensus well right now, given recent trends. In your opinion, if you *HAD* to adjust, do you foresee yourself changing this in any one direction, higher or lower, based on what you are currently seeing? I'm just curious lol What does your gut say? aha

Higher. I am still wrapping my mind around a deepening cyclone near the 40/70 BM delivering minor accumulations to most of the region. But digesting facts from Mets, including you, is slowly making me realize we're probably not set-up as such. It's possible snow amounts increase for those in the purple and blue but stay as is for the rest of us simply because of dry air but better forcing getting into some of the banding.

Re: January 4th Snowstorm: 1st Call Snow Map
I am looking forward to some sort of post mortem once this thing is done and gone. After all of the model waffling and endless possibilities...I am looking forward to finding out what actually ended up transpiring when all is said and done.

One thing to note is with a rapidly deepening LP, we will likely see a strong Deformation band form. To either side of that their could be some subsidence and therefore low totals. Similar situation happened with Nemo in Feb 2013, deform band went through CCT, CLI/ELI and WLI and NYC suffered a bit.

Yeah, it really is counter intuitive. I can't honestly believe it either, even with the trajectory it's just odd to me. What really is grinding my gears, though, is the "jump". I can see the argument for the surface low as it follows the thermal gradient in the ocean, but the upper levels.....I don't know why that third piece kicks it instead of just seamlessly phasing in. I don't get it. That said, the continuous representation of the precipitation field by modeling is disconcerting for sure, and to bet against that would be tough, even for me lol Lastly, I hope you didn't let me influence YOUR forecast aha that would defeat the purpose of making one!! haha I won't lie though, I'm not too upset that I chose to largely sit this winter out, mainly because of this storm lmao

In eight hours, our second piece of energy has traveled from the ND/SD border and is now in southeastern NE. THAT'S HAULING.

No Hyde I think he may be right big cutoff and dry air looks to win out.

HRDPS looks healthier with the western edge of the precipitation shield so far....

I still think its conservative but they always go low because they could raise totals tomorrow. I would go 3-5 NYC, 6-8 Jersey shore.

According to SPC Meso-analysis our surface low has actually retrograded toward the Gulf and is now due south of the central Keys lol

Re: January 4th Snowstorm: 1st Call Snow Map
Anyone have the latest run of the SAM? It's the only model I will trust with this storm.
Thanks for all the hard work boys and girls, to be continued in some form in the am, maybe.

CMC is out to lunch. Low totals and I don't think west of Red Sox Suck is only going to get 4-5 inches, sorry.
