I'm not sure how many W - E  oriented valleys there are in NE...

Once in NNE, there aren't all that many roads running E-W, much less valleys.

Have planned to drive to Ft.Kent Wed evening, to look at logging in a deeryard in the Allagash. Don't see the snow doing much that far north, but might make for an interesting commute, especially for the 6-hr drive back south Thurs aft/eve. We may need to reconsider (12z gfs dumps about 20" on RUM, 15" on AUG Thurs, lol), but have until Wed aft to make that call.

Thermal profile as advertised on NAM is similar to 3/31-4/1/1997, although the order/direction is a bit different.

 

Snowfall map through 75hr has 6" in DCA, 9" PHL, 10+ NYC, 13ish KTOL and a max around 20 near CT/RI/Mass. tri-state border.

Eh, I don't think that's a very good analog. Very different setup and different temperature structure.

Has any other model matched up with this kind of temp profile so far? I don't think I recall any...

 

Some of the SREF members did, but most of them don't. Even if the NAM did verify, its a ton of snow before it goes to RA- or even some pellets to FZDZ in the interior as 2m temps stay quite cold.

It actually tucks east enough that the winds would probably be more northerly than they were in 1992. Less coastal flooding and less shadowing that way. 

 

Totally agree....in 1992, the low was tucked in over Delaware for a while and high pressure was elongated east-west causing about a 600 mile due east fetch into the coastline.  This doesn't look anything like that, much more northerly component in the wind field

Not a good analog when looking at the big picture, but the alignment of the 850 freezing line during the height is reminiscent. 1997 was rain to pasty snow. This looks like snow to paste/rain, back to snow, assuming current trends are correct.

3-4" QPF in SE NE.  

 

0.5" line by CON.

 

I do not envy the media for this one. Major bust potential.

 

We've been pretty lucky near CON since I've lived here (last 6 years) avoiding these types of sharp qpf drop offs, but it seems to have been pretty common in historical MECS+ events

I don't think rain is a big worry interior . Not with that high and cold 950s

Rain is a huge concern here, always has been.

Good call. You've been harping on that for days.

We'll see if everything keeps pushing NW, but it's still hard for me to believe that the EURO is that far off base 48 hours out. And yes, I know it has busted within that range a few times this winter, so maybe it isn't that much of a stretch.
