Other then some north tics and some south tics, I think the areas that have been pegged last several cycles do well, And i'm talking about front end snows, Reach around is a wildcard.

Yes I think we are narrowed in and locked for 6-10, but I think 8-12 is very much on the table.  Look at that radar man.

That's what the reggie has but i'll believe it when other models have it, GFS is pretty far south and right now, Its the southern outlier so lets see if it moves NW at 12z.

Yeah looks like it. Definitely a little colder than the nam on the front side 

Reggie is really good for those who stay mostly snow. Big hits there to ORH. But southeast where they are relying on Monday’s changeover it was kind of weak. Prob like 1-3” of slop finish.

Okay ... in this lecture, ladies and gentlemen, we target Great Snow 1717 for migraine headache.  See if you can identify the exact moment the temple sends a shard of pain behind the eye sockets -

 

Here is the NAM's FOUS grid for Logan off the 12z run ( on right is Laguardia, but ignore that block for the purposes of this pain administration - )

The data fields I bold'ed above are associated to Phase II, tomorrow into tomorrow evening, and these numeric values are important.   The "25" and "46" on the left, are QPF...  That is .71" liquid equivalence occurring as of 36 hours from 12z this morning, the time of the NAM run cycle.  The fields on the far right, ex "0000098" are the temperatures in C at 980, 900, and 800 mb levels.  00 = 0C.   98 = -2 C.  So you can see... the next interval is 009793, which correspond to 0C, -3C, and -7C at those respective levels.  

I think this is in process of still modulating in the guidance however.. .The reason I suggest that is because of those middle values, "35" and "31" - those correspond to wind direction.  35 = 350 deg around the dial starting from N ( 0 deg/360 deg). And so 31 = 310 deg and so on.   Here's the thing, typically you don't get bigger QPF numbers on wind directions that have backed that far into a W direction. 

When you see a NW wind with QPF, that is part of the notorious ANA fake-out effect.  And, I can tell you from experience, the NAM has no compunctions about lying big numbers with drying flow ( :arrowhead:).  However, since this entire solution is more so trending toward more reliable guidance types ( Euro and ..whatever, they're all better than this model at handling synoptic anything), I would not be surprised if the next cycle has more of a 01 of 02... offering NNE trajectory that fit matters better. 

So, this immediate abv paragraph is just offering some reasoning why we may not want to shed the NAM's .7" snow burst tomorrow.

I also like the fact that at 18 hours ... .32 has fallen with a +4, +4, 0C column.  Once you get NW of the city... that could be +1, +1, -1 say FIT -ASH... that's your bust axis for Phase 1

Dude you’re going to get good snows. Take an edible. 

I'm high on snow.  The scene is so great up here now.  Long walks in the woods, up to ridge tops, and in parts of the woods that I don't go at other times due to moisture, ticks, mosquitos.  It is so awesome around here, and the thought of a thicker cover, and pack that could last a few weeks has me all fired up lol.  You really should up to the Lakes area this week.  Take the kids snow hiking, or just beg your wife for a day to drive up and chill.

Well there’s work and school lol. 
 

Hopefully we can salvage something down here.
