30.8/26 steady zr

33/22...hoping for zr instead of ip.

My gut says your mainly ip, but well see. Warm layer seems to wash out a bit up there by 4-5z

Down to 32/23 on an east wind. Definetely an odd temp map

2008 was less of an elevation around here in SE NH closer to the source region. It helped but damage was widespread and even extended parts of Haverhill near the border

It's pretty suprising how cold the GFS is at the surface. Basically keeps BOS near 32F through 9-10z Thirsday morning

Pretty wild in Andover when that ripped through. Super wind blown but somewhere around a half inch the best I can tell

1.5" 23F

GFS looks pretty good tonight

00z NAM is slashes that QPF.

Pretty solid 3km run for NH. Colder south of MHT

6.8" light sleet w/ snow grains

30.1 and pouring ZR.

Congrats 

6". Peltfest at 12F.

I don't see anything to stop it really...esp in NE MA and SE NH. if anything, we're only more likely to get a mesolow forming out to the east of MA to strengthen the CAD. Outside of being on the wrong side of the CF, the only warming mechanism I can see is latent heat...but once in the barrier jet, it is going to easily offset that I think. The biggest question for me is how far SW that secondary push of cold air gets.

 

Should be getting to Ray soon.

Just passed through here just north of the border. 24 to 21F in about 10 min

We'll see how far south that gets but I think anyone who gets into that core of the Arctic air wth teens is lights out for any shot at liquid...won't see freezing in the event. I don't see any mechanism to remove it. If it can filter down into E MA, then they are in dip doodoo for lots of icing. As that will give them the necessary buffer needed for latent heat warming before the mesolow cools them again later morning. 

Its definitely pressing at the moment. Passing through MHT now and south of 101 on the meso sites

PSM 24F to 18F last hour. Definitely starting to get some NEerly drain from SW ME

I hear ya. Anyone getting substantial ZR is keeping it for a few days. You wouldn’t need that wedge to overperform much to keep the IP going longer down there. Hopefully the warm nose ticks a bit cooler to keep the hydrometeors from completely melting so we can make the transition back to frozen in the cold layer easier. 

Generally along my thinking too. Probably more in the way of sleet after it flips in S NH. Probably get some zr but hopefully not damaging.

Looks like half of my 1.4” QPF on the NAM is sleet. So maybe 8-12” snow and 2” of sleet on top.

I'm really hoping we waste enough qpf as snow/sleet down here before we flip to ZR.

Congrats dendrite that run. 

ML fronto ftw

Its warmest layer at MHT 12z Sunday is the sfc. Complete garbage 

Flipping over to sleet with a few flakes mixed in. 0.8" 

Flipped to all sn 

Definitely starting to wash out a bit on CC 

Starting to mix in some flakes with the sleet once the heavier echoes moved in

00z NAM soundings show that pesky H8 layer lingering at MHT/ASH through 3z. All snow aloft even down to LWM by midnight (6z).

3km is similar. Pretty close here around 3z. Well see

Mix of sleet/rain. 34F. Atleast southeast of MHT, well need to wait til after 3z if its gonna happen
