Yep, this would bust forecasts hard in S NH

I ran a couple skew-t's for my hood and it showed what might be a flirtation with sleet, but it was only razor thin and only briefly.  So much for all the excitement of the NAM runs last night.  Hopefully the GFS and EC will hold.

That map looks too low for S NH. AFN/ASH are all snow through 12z with over an inch of liquid equivalent.

Looking at soundings, that'd be roughly 6 hours of sleet. Still gonna get a foot on that run given the snow-to-liquid ratio, but not sure we'll hit NWS forecast of 18" in this scenario. Probably wouldn't be a major bust then.

Everything has trended warmer in the boundary layer. Even the RPM is bringing the surface 0c isotherm to Hartford for a while in the morning Sunday. Not sure if that's overdone but it is notable that everything has come north some this evening. 

Last night it was all south so you upped amounts lol if HFD is above 32 I will be 35

Here's probably a more accurate clown map (though prob a little too light near coast). Yeah, 18" is in trouble there I think on most guidance....but I'd expect you'll crack double digits pretty easily

I honestly think Kevin's big ice call might be correct even here.. but we'll  see

I see no way out from about RI / Mass border on SSW line to DXR. I think Ginx, me, anybody up into Union to Putnam down to Ryan to Iceberg to Spanks to Hoth are in deep doo doo. Euro ain’t gonna be wrong this close in. It’s prep time

Further south in CT, yeah maybe....for you though:

Those totals ramp up pretty quickly over a few miles in SNE.  I'll take my 14" and run.

So the freezing rain can stay north of me? That would be great. Kevin can have it lol

Remember the pdfamily temp map?  I'm thinking of that from Rocktober any how few pws reports were showing up.  Maybe this could be similar, though not as wide geographically.

Define particularly

Could there be a narrow zone of 1/2" of ice accretion? Sure. But I'm not that confident in it.

Southern areas may battle a more easterly component to the wind for a bit and warm about 0c at the surface. Central/Northern areas lose to much QPF to sleet and snow.
