I hope everyone is ready for a large snowfall. Every meteorologist seems to be predicting the same amount for us. They are all on board for 12-18 inches of snow.
The snow will start to fall just before the morning commute and then continue all day into the night.
The low is traveling a little faster than first expected so the snow should stop over night Tuesday not linger into the day Wednesday, but then there is the big clean up for Wednesday. There will be times on Tuesday that the snow is falling at 2 inches per hour.
The other problem will be the wind. You should prepare for some power outages.
There is a chance for blizzard conditions. The National Weather Service defines a blizzard as a storm which contains large amounts of snow OR blowing snow, with winds in excess of 35 mph and visibility of less than 1/4 mile. These conditions have to exist for a minimum of 3 straight hours to be called a blizzard.
Here are all the different snow total maps that I found

this one from channel 5 in Boston
If anything changes I will post an update.
Enjoy your snow day
