The more east trend of the storm peaked last night and has since returned some precip to areas of western New England. Here, I think it will be an all snow event, but you will not get into the heavy duty precip like areas further east. Here I am expecting a good 1-2" with isolated spots getting around 3", especially Putman, CT, may see up to 3".
Further east we get to Worcester. From Worcester to just inside Route 128, this is where the "jackpot" for this storm will be. Precip will blossom on this area and snowfall could get locally heavy just in time for the morning commute. All said and done, a gloppy, 2-4" is likely, again with an isolated spot picking up 5". Someone N&W of Portsmouth, NH may wind up with closer to 6" of snow.
East of the "jackpot" zone, this is where it is tricky. I have moved it a tad to the east, but am still keeping the city of Boston on the line between the mix and the mostly rain to the SE. Here, you will likely start as snow, quickly turn to rain and may quickly turn back to snow just in time to get the last moderate to heavy band to go through with perhaps a coating to an inch. All said and done here, I put a general 1-2" of snow, but most of it will be washed away. SE of here, you don't have to worry about this one. All rain in the green area. Sorry.
The true "jackpot" with this storm will be northeast Maine, Downeast Maine, with perhaps as much as 10-18" of white gold. Much of Maine at this time from just inland of Portland to Caribou, including Bangor is under a Winter Storm Watch for possibly 6"+. Some will get much more than that and see near Blizzard conditions at the height of the storm. Enjoy it.
Bottom line, the snow moves in overnight in SNE around 1-3AM. It only lasts about six hours, but it could be an intense snow for about 2-3 of those hours, so stay tuned. Further north into NH and ME, expect the storm to move in late morning to early afternoon from south to north, but in northern Maine, the snow may continue into Saturday morning with near Blizzard conditions Friday night. Ski areas will do great with this one. I would not be surprised if one of the resorts picks up a quick 20" of powder out of this one. Again, enjoy it. I will.
More on the extended forecast, which stays extremely wintery with more chances of snow later.
