the euro is pretty darn warm, fwiw. more than 12z was too. it now has the 0C 850 line to MA/NH border by 12z tom. 

 

I just looked at the 0z Euro and was shocked to see the QPF for 12z Sunday and then just looked at 925mb temps and there is quite the temperature gradient.  There are going to be some very impressive snowfall rates tomorrow across portions of central MA into southern NH.

scoots could get more than you depending on how quickly the low levels warm near BOS. if they hold, cold...it wouldn't surprise me.

 

I'm thinking I get similar amounts to him. Maybe an inch or two either way.  It wouldn't surprise me if BOS gets a hair more than him. Obviously temps are different. Hoping for 5-7" here.

The Euro at least keeps it cold before the torch at 850... and 6z it's still like -4c at 850mb while the 00z GFS is near 0.

 

That shortwave looks great on water vapor... almost have to think that it's not done trending northwest.

I agree and it seems like models have been starting to pick up on that

Was just looking at some of the NAM soundings and they definitely are quite intriguing.  The question at play is how warm do the low levels get?  Pretty much on the line of sleet vs. freezing rain but it definitely needs to be watched.  

 

I'm thinking you have ip, but not zr.  Maybe a little as the dryslot moves in, but that would be it.

 

You'll may be in the weenie sweet spot for this one.  We're good to go on this one.

 

I'm not worried about much at this point, though I'll take a look at the upcoming models regardless.  The trend to warm is worrisome--glad it's 8 hours out and not 2 days with that trend.

 

Um the .01 increments on the models are producing some good rates

 

You should have seen what we managed up here with extremely light amounts.

I don't think the trend to warm has any affect on you at your location at all lol

Exactly what I was trying to point out earlier when I was digging into the models. It appeared to me that the warm air  push aloft is a bit stronger in CT and south of the MA pike with a significant latitudinal gradient so it's possible the pingers are a bigger problem south than some are anticipating. For BOS the 850s hold out a bit longer but the battle is against the onshore flow at the surface.

Given the pretty recent uniform move, I don't see reason to expect that it has.  We'll know soon enough though....a couple more hours and just sit back and enjoy what happens.
