Looked at the 12z GFS very quickly.
The primary makes it to around Albany before transferring to the coast. Seems like a classic late developing miller B.
Coastal develops so late that really only Central and Northern New England cash in.
The ice threat looks minimal as unlike the last storm, temperatures are warming at the surface.
You do have that 1036mb high over SE Canada but it's retreating and not far enough South. We would have wanted it over Northern New England.
850mb freezing line moves well North after 12z Friday.
Anyone North of the 0c line on this frame is good for about a 6 hour period of Snow changing to sleet and then some freezing rain before everyone flips over to plain rain. South of this is mostly sleet/ice changing to plain rain.
Even over Rockland sounding show the surface around 30 which won't be cold enough to cause significant icing issues, especially since it will be short lived.
If you look at the trend for the last four runs, it did actually hang onto the cold air longer after trending warmer the last two runs.
Still time to go but we're a long way away from a big snow storm South of I-84.
