DEDHAM, Mass. — A new snow map issued Friday by the Boston 25 Weather team shows the possibility for up to a half-foot of snow, with higher isolated totals, in parts of Massachusetts this weekend.

After some possible coastal flurries on Friday, the winter storm arrives with snow filling in after midnight across the region and continuing throughout most of Saturday.

A winter storm watch and winter weather advisory have been issued due to the approaching snow.

“Around midday and afternoon, it does look like some of the steadiest, heaviest snow is probably going to be along the immediate coastline,” Boston 25 Meteorologist Shiri Spear said in her morning forecast. “The whole thing ends by the evening. So by 6 or 7 p.m., the snow is over in Boston. It takes a little bit longer to shut off on Saturday night on the Cape. ”

At least a few inches of snow widespread are expected.

Higher amounts of snow are likely in central parts of the region and coastal areas, too. A few isolated spots could even get up to 10 inches of snow.

Boston 25 Meteorologist Tucker Antico says that the incoming storm is the “trickiest forecast of the season.”

Parts of southern New Hampshire also fall in the band that could bring up 5 inches of snow.

On the heels of the fresh snowfall, extreme cold will flow in Saturday night with subzero wind chills. That blustery, brutal air will last all day Sunday, with the risk of frostbite

“Feels-like” temperatures in parts of Massachusetts could be as low as -20 degrees on Sunday morning.
