The National Weather Service’s Boston office is forecasting 6 to 8 inches of snow across Massachusetts from Saturday night into Sunday. Some spots may even see close to a foot of snow.

The snow will arrive Saturday between 10 p.m. and midnight. Once it arrives, it will hit the ground running. The majority of the snow accumulation will occur between midnight and 7 a.m. on Sunday. There will be some light snow and flurries between 7 a.m. and noon but very little additional accumulation.

A winter storm heading toward Massachusetts is expected to bring widespread snow and make travel very difficult.
