Yeeeaaah getting storms to "back into" here like that seems like a lower percentage shot in my untrained opinion...(any examples of when that has actually worked? That is, where the models ticked west in the short range and we ended up with a nice hit?)

Maybe not huge hits, but there are plenty of examples of storms that trended NW last minute. Just this month the Dec 8-9 snow, March 13-14 also trended NW (especially with the sleet line), Jan 6-7 2017, and even Jan 22-24 2016 trended NW (especially for NYC). We've seen it before. Either it's the precip shield extending farther West, or it's biases on the models. We've seen it time and time again.

I guess there's a bright side to this mess...usually the most painful winter periods where we get no snow usually include areas within a 3 hour drive getting something decent. That's not the case right now. Nobody for 1,500 miles of coastline has anything exciting to track so there's that at least 

Maybe this will some type of unicorn storm. But I really want to say is that I love the dog in your profile picture.

Usually what happens is the storm is slated to hit us all along but screw NYC and BOS. The storm trends more north and west and they end up getting nailed too. The whole "north trend" and 'snow magnet" is a SNE thing. Usually doesn't work here. You'll learn soon enough.

Right. Instances like January '16 are rare. NYC did very well but BOS ended up with 8.4". NYC does extremely well splitting the difference between DC/BAL climo and Bos's. As does PHL.

EPS members seemed like a positive step. Nothing huge, but it was an improvement over 0z. There are a couple of additional members that now get us into warning criteria snowfalls and a couple of the big members have bigger snows closer than they were last run. We have 5 days to go. There's a ton of time for small shifts, which would make a big difference. I also like that the Ukie is a big snowstorm for us. Maybe it's just one run, but I'd rather have that in my corner than not at this point.

I agree that Boston is sitting pretty and by far in the safest spot, but interestingly Cranky threw something out on Twitter that he thinks this is either a hit for everyone or no one, which I don't agree with because I could easily see Boston getting destroyed and everyone else watching helplessly as it happens, but he knows far more than I ever will so......

Some storms definitely shift west as we draw near, but they shift east as well. There was a storm where NYC was supposed to get like 2 feet and I think they got like 6 inches because it was just a tad east. Think it was a few years ago but not sure.

There's also a former NWS employee on Accuweather forums who has a really good track record of seemingly calling these things and he seems to think there's a good chance this is happening, FWIW.

But why does he say that?  I like to know how my sausage is made.  Yes guidance shifted west but why should it continue.  

I have no idea. Probably just a gut feeling on his part. He's basically flipping a coin, but I believe guidance will keep shifting NW, but that's just my opinion.

Keep hearing this storm will have to back in from the east by quite a bit. I think that is a false assumption. If this plays out the way the models are now suggesting is a possibility, chances are good we see a storm form off the SE coast and ride up North just off the coast.

Yeah, it seems our best chance is for a low to pop along the coast. I'm not sure that we are rooting for the initial low to be too close to the coast. You and others would no better, but my guess is we need some separation.

I just want to know who the he!! Franks Weather is. For all I know he is just some Joe Shmoe that bases his thoughts on wish casting.

I see it now...he is the Weather Mastr....mystery solved. It's coming west folks...I'll alert the media.

Yes, it won't form off the coast and back in; that doesn't happen for us. If this works out it will ride up the coast and look pretty different than current projections.

If you are worrying that the storm might end up too far west where the DC/Balt corridor has issues with precip type I probably wouldn't. Though the shore might have issues the cities are firmly entrenched and deep within the cold. Short of a sneaky warm layer at mid-levels (sleet/fr rain) about the only way I can see at this point where it could possibly become an issue is if we see the low absolutely bomb out and phase just off the VA shore and get drawn inland to our south.

Hey guys I know it’s the Nam but I felt like it was a super good run and continued the trend in the right direction. Better heights in NE. 12z Nam had it around Syracuse Ny and a line from there. 18z Nam has it over western Maine. Also, if you look at the gfs around 90 hrs on the 12z, it has the main bundle of energy wrt the northern stream centered over Green Bay Wisconsin. 18z Nam has it centered around Mason City Iowa. Big difference to allow this thing to dig even more and catch up to the southern s/w. Definitely some signs that this thing wants to throw a surprise.

Canadian ensembles have consolidated into tracks that are more clustered around the op.  About half show snow for DC now around January 4-5, which is a significant bump up from 00z.  Most of them are pretty light on qpf though.  One member goes nuts.  It gives DC 2" of qpf as snow, and then nine days later it drops another 1.5+" of qpf as more snow.

Sounds more like a member of this board than the Canadian ensembles.

I'll take the one nuts member, some brutal cold after it for awhile for a slow thaw, and then winter can be over and we can start to warm up come February.
