The approaching storm could be the biggest of the season for Boston.
It's a widespread 6-9" for much of Greater Boston, with a bit less right at the coast, and far less in Northern New England.
The heaviest snow is expected to fall during the overnight hours, with almost all of it falling between midnight and dawn.
Snow falling at 1-2” per hour is possible, making it difficult for travel. Expect reduced visibility if you have to be on the roads.
In far southeastern Massachusetts, it will be warm enough for the snow to change to a wintry mix and/or rain overnight. That will cut down on snow totals there.
As of now we’re expecting 1-3” for the South Coast and Cape, with less on the Islands. Three to six inches of wet, pasty snow is likely for the South Shore and areas right around Boston.
From the city just north and west, more like 6-9” is anticipated. Totals will drop off in Northern New England where 1-3 inches of snow is possible.
