this could easily change, but as modeled right now the one thing we actually have for the first time with any of these systems is some semblance of an E or NE flow at 850 for a time. that would help out coastal peeps further up the coast and maybe a bit further inland as we would actually have a mechanism to transport some moisture westward.

Yeah, if we can make it through this next set of runs without that vanishing...1 or 2 runs with previous systems at least a model or two had some decent NE flow only to lose it...we should be in good shape.

My concern with the GFS is it's overshot left with almost every one of these systems while the Euro and GGEM have tended to be too far right until the end.  I think the last 2 even the Euro eventually overshot left for a run or two.  Much stronger features this time which may be able to offset the flow which wants to move the trough east as it's digging. 

 

If I had to forecast it'd probably be along the lines of the Euro with an eye to a more easterly solution at 3 days out.  Not sure how much I can buy the GFS with the GFS most left, Euro middle, UK a bit right of the Euro and the GGEM flat.   

 

Plenty of time.

I don't believe the GFS is right with the track, it will shift to the southeast a bit and get a bit more in line with the 12z EURO track.  QPF will increase and intensity will as well.

Despite the fact that it is trending NW, and the Euro is trending NW, you expect it to now trend SE and give you a 2ft blizzard?  

 

Well let me just say that I expect it to continue to trend NW, stall for a bit over Ptown, move north into GOM slowly then rot out slowly to the NE.  There will be an initial weenie band of waa snow that should lay down about 6 inches over Dendrite-land.  Then the CCB will slowly rotate over me, stalling and rotting and leaving somewhere close to 2.5 of qpf with high ratios.  This is what I expect to see at 0Z or maybe 12z.

 

So there.
