Updated snow map, due to current short range models and radar, there is also some geography/geology that goes into my snow maps.
In terms of snowfall, the 10+ area expanded southwestward do to banding as well as westward up in Maine. This area will be heavily influenced by banding. Some areas will barely make the 10 inch mark while others go well over around 18 inches. Some areas of Maine could be measuring up to two feet depending on exact track. the track of the storm of this strength does a little dance of the wobbles.
Basically all areas have seen an increase except the outer cape where 1-3 inches is anticipated.
The best chance for Blizzard criteria of 3 hours of sustained winds or gusts of 35+, white out conditions all being met is Coastal Maine, Coastal NH, Coastal southeast Mass portions of the cape depending on how long it takes for it to change to snow.
Blizzard conditions are possible as far west as the yellow line, especially with the heavier snow bands.
coastal concerns are of great concern.
Please stay off the road especially in Eastern New England today.
