Bostonians can expect between 4 to 6 inches of snow, with higher totals of between 6 to 8 inches in areas just northwest of the city. Southeastern areas, including the South Shore and Cape Cod, will see lower totals due to a delayed arrival of colder air.

After days of balmy weather, City is slated to get buried in snow and then hit with an arctic blast expected to unleash a potentially life-threatening chill.

Showers today then snow moves in early Sunday and lasts into evening. The coldest air in years arrives Monday.

M.L.K. Day will look beautiful, with plenty of sunshine and dry conditions. However, it will be the start of our Arctic blast.

Colder air is already arriving and will continue to funnel in through the day. This will provide frigid temperatures for our mornings to start the week and also help to keep temperatures below freezing through the afternoons.
