As WAR expands, do our snow chances increase? First wave may produce a middling event-solid advisory and possible low end warning for MLK Weekend

It is that trend which is leading me to believe the NAM is not going to be correct but like I mentioned, we have seem several events over the past few years where we saw the NAM starting to cave towards other guidance and then all of a sudden other guidance started caving in the other direction. The direction I am leaning in right now is majority receive several inches of snow...that's how I felt yesterday morning when I posted in the main thread that I think this surprises...but I want to keep an open mind right now and understand we have seen some wild shifts inside 48-72 hours in recent years. 

The NAM had a massive shift on the 12Z run for 12/20 giving warning snowfall for CT and adv level snow back to NYC...in 0-6HR range. Which was obviously wrong and didn't happen. But inside of 6 hours was something i've never seen before. I don't trust that model at any range for any storm pretty much ever. 

That said im pretty much in line with what Will said. GEM settling east and EC coming NW, a track inside the BM to ACK

The 12z ICON evolution offers an outstanding compromise, either because it's doing a good job, or dumb luck - either way, that solution doesn't look terrible if you throw everything into a blender and pour a cup of forecast

I think I saw dendrite talking about this shortwave energy in one of the pages I was catching up on from overnight/this morning but maybe the NAM is being a bit too aggressive with it...too much influence from convection (though convection doesn't look like a big deal). But I guess there are two ways to look a this:

1) The NAM is totally off its rocker

2) It's a feasible reality and something that shouldn't be discounted, especially at this range. 

We all know the NAM isn't the greatest synoptically, however, it's not like it's presented output here is something that is outlandish or unlikely. It basically just continues indicating there is alot of spread. I'd be nervous putting snow maps out right now, especially if on the aggressive side.

Seeing this particular depiction by the NAM makes me think of the Messenger shuffle.

I was expecting Canadian suite to come east a bit like 06z did….someone is going to be quite incorrect inside of 60 hours. 

yeah, unless 12z is the suite we see an adjustment from the globals

Some GEFS members almost as far west as Reggie but not quite

And furthest west EPS member still tracks just east of CHH while OP RGEM tracks into interior SE MA.
