This is such a hard forecast for Boston and NYC. A month from now it's kind of a slam dunk big snow but methinks we're a tad too early at least in Boston.

 

Agree. Ryan summarized it excellently on his blog.

 

Would feel more confident if we even had the antecedent artic cold that we had earlier in Nov.

 

With a toasty boundary layer + questionable snow growth, I could see us snowing for hours with little accumulation to show for it in metro Boston. At least as depicted on EC/GFS now.

 

Hoping for more northerly flow as depicted on 18Z NAM / hi-res NAM / RGEM... maybe we can get a more NE-SW (vs. N-S) orientation of the coastal front that would favor our area.

I feel my chances are better in Princeton and I convinced my wife of the dire circumstances requiring us to travel tomorrow night...lol.

I still think snow growth won't be that terrible. It's not classic dendrites, but I feel that strong UVM and a relatively warm, moist profile will produce some big aggregates and heavy snow where the atmosphere is near and below 32 at the surface. It's really the boundary layer near BOS. NAM and RGEM would be a flip and then cool to 32F snow. I actually feel semi-decent for the western hoods of BOS.

Funny Brett brought up Dec 2012. I actually have a vision of a classic Milton to Taunton CF..almost due N-S for part of the time anyways. At least I could see that in this case.

Yeah, obviously way to early to talk exact locations, but whoever is on the west side of that might be in for a big surprise.

A 50mi shift E and a lot of people will be wtf'ing the forecasters.

It kind of sucks for everyone that's it's coming on a huge travel day.

That's actually a huge commercial delivery day too. Lots of trucks on the streets. Gonna' be wild if it thumps snow to the coast, even just a few quick inches.

I sure hope power loss isn't an issue. Can you imagine millions of thawed turkeys with no place to go? Oh, the horror.

First map of the season.  Ranges are a little broad.  Will tighten them up tomorrow when I feel more confident about the push of warm air and where it lines up.

Thanks for putting out a map--good luck with it.

I don't think there's any scenario that would have that as a problem. 

 

Good for folks that the SREF is colder.

I need 8.5" to make my 2nd snowiest Novie on record, which is doable...maybe like a 40% shot.

I need 10.7" for my snowiest, which is probably about a 15% shot....long shot.

Need H7 low to trend east to have a real shot at the latter.

My official call is 8" (6-10").

I think the cf made it 1/4 mile west of me. So fukking close...

 

Good memories lol... we could have walked to the other side of that front.

Family coming up from Philly Tuesday for Thanksgiving. I'm hoping this storm will impress. 

 

 

2012 broke many Boston weenies.

I hope you're right, Coastal... I like to flush out all the potential flies in the ointment (in addition to the obvious that we're up against climo!).

I don't understand why he is saying snow growth is so bad. I generally think that gets over emphasized anyway, but it certainly looks decent with this. The issue that I think may hold amounts down in the lower spots is temps at 34 at least until sun goes down
