Yeah we were tossing those NAM solutions with lots of confidence at 72-84 hours. It was well beyond what even the most amped globals had. I think the most surprising aspect is how little the euro has moved. If anything it moved south until finally ticking back north a little at 18z. I kind of expect a pretty even compromise between it and GFS now which will end up as the common 70/30 from a couple days ago. 

Your area is probably the most interesting of anyone on the forum.  That southern Middlesex County zone has been consistently modeled as the battle ground on all guidance.  Like could certainly be 8-12" of paste, or like 2-4" of 4:1 slop.

Looks like qpf is getting reduced on the NAM (no suprise) and ICON.  At least in Maine. Alas.

These early runs have a been a little flaccid on dynamics. But some of these mesos were also pretty bonkers to begin with. The massive 1-1.5 QPf getting well inland never looked that realistic.

I’m hedging on the lower end here at the moment. I’m not convinced of some of these rates but we’ll see. If we can get a temporary bombing low scenario which isn’t impossible for a few hours, then we might be able to rip if we stay on the cold side. 
 

Id feel a lot better on winter hill, lol

Sane and realistic.

Elevation at that same latitude would certainly be favored.  What a legendary snow spot Winter Hill is… decades of wins in winter events (proven on the forums) compared to surrounding areas.

Hopefully it can go isothermal paste for your current spot.  How many times is “the Pike” the boundary zone over the years?  Could be another one.

Ahhhhh from Totally Screwing RI to…. Totally Screwing RI?  Ya.  Same Picture to me.

It's amazing how the two E to W  highways (Pike and RT2) are often viable dividing lines wrt frozen precip in winter storms with marginal temp profiles.

This area is pretty often on the correct side of the “495 gradient” despite being a little inside 495. But so many times I’ve seen huge gradients like 2 towns east. But you do get these events sometimes where it’s really more like ORH is the line…the lower part of the city even might be on the warm side of the gradient. This happened during the ice storm in 2008. Also during the March 2023 Firehose event. Lower elevations literally had 5” of slop and it was like 15” on winter hill and then 2 feet another 5 miles NW. granted, that was the most extreme I’ve seen.

GFS looks just a smidge colder near here than 18z but at this point it’s noise unless it does it again another couple of cycles.

NOP usually means rain in the lowlands up to Rt 2

Just rots over 495.

495 does seem to be the cutoff for many storms. Growing up a mile from the ocean in Peabody, we were often on the wet side of storms, but I couldn't tell you how many storms were mainly white in Lowell (including the 2008 ice storm) where it was just rain only a few miles SE of here. Once again, it seems like 495 will be where the R/S line is. I think Ray will do much better in Methuen than his old place in Wilmington.

ggem is warm, too. 0c h85 is north of here

Oh' I know...

Some of the locals seem to be all in on the dynamics being close enough to the coast to ignore the ocean temps?

A large area of light snow across the north... with a narrow zone of heavy snow near the gradient.  That feels like the right outcome.  It's crazy that gradient remains in question and will have such a big effect on sensible impacts.

yeah I agree, probably not far from the truth.  I'd feel better with a closed ml low traveling over the south coast, but this whole thing looks like a mess - which lends me to believe ml's will act accodingly, including precip shield- with more warming than some of these isothermal to 128 depictions we saw.

The 2nd deform zone will be the wild card for some decent totals in SNE/CNE.  Hoping for warning snows into downtown Greenfield but somewhere between the Berkshires and Worcester, there will be a narrow band where a few towns get smoked.
