Is that all snow along the South Coast?  Pit1 must be obliterated.

SN+ at Pit2.

Sleet is just inland

Where you at ?

North of white plains NY - like to the left of Stamford/greenwich.  If we can do it so can you.

[Typhoon Tip]

Too much energy expended in the semantics of the "SWFE"  when the term never should have been invented in the first place.  Meteorology already defines this type of precipitation cause by isentropic lift.  That's all it is.  SWFE is just overrunning, because the warm air outpaces the retreat of cold air, and thus... is forced over it.   

The other thing is that it is not that uncommon for isentropic events to morph into coastals.   Sometimes there's a lull as the IB moves off, then the coastal gets going. Sometimes the transition is smoother... it's all kind of variant.   

We'll see what happens tomorrow but it looks on the PP layout like a coastal that is moving too fast to really clip on the way out. So we end up with a cough CCB decay ...

Yea but what I’m saying tomorrow is a different vibe.  
 

It’s not SWFE. 

Tomorrow isn’t but it’s not going to be enough to reach the upper totals

[SouthCoastMA]

the flakes have been smallish all day. hoping to get 12" before any mixing 

[bobbutts]

8"

Nice . What do you have now.. 18”?

Kinda stalled on 16.  Light sleet right now.  If we can flip back we’ll grab a couple more.  

[dendrite]

Whatever…it’s a term Will and Ekster coined 2 decades ago with SW flow aloft. Overrunning, SWFE, isentropic lift…same diff.

what do you have

[ineedsnow]

surprised Eric Fisher has us in one of the best spots for 2ft.. but he thinks its possible with the added snow tomorrow

[Damage In Tolland]

Do we have posters in the Keene, NH area? It looks on radar like they’ve kind of gotten screwed

I am right at 16.  Compacting now with sleet.

I don’t mean there. There was reports of sleet into Vernon which is near me 

Either maybe something convective went through and it was heavily rimed flakes/graupel or maybe nucleation is getting poor at times and you’re getting supercooled droplets in the cloud layer freezing in the cold dome.

In the end it just comes down to a number. The liquid equiv will be what it is. By the end of the week the pack will look the same whether it started as big dendrites or little plates and needles. 

Yup, models will be close to correct on QPF totals give or take a tenth or two. 
Maybe not a lot of 18” totals but plenty of meat in the pack. 

[ineedsnow]

snow growth getting much much better here now

[tavwtby]

pics are 1.5 hours apart and 4" different...12 hr measure at ~14" now still at 10°, wind gonna make it tough for final measurements tomorrow morning.

Oh is it? I didn’t know that 

[scoob40]

CEF reporting 13" per Western Ma News. Not bad for this usual snow hole.

[MuddyWx]

7PM Update:

11.1" (2.0" new last hour with the CF coming through)

22F

[Baroclinic Zone]

Spiked up to 23F.

[HIPPYVALLEY]

Even with the less than ideal snow growth it just has not let up all day.  
Good stuff.

Yup. I was concerned about ratios. 

1st core is 5.6”/0.44” here

13:1 is still solid

That’s pretty good.
