Snowfall should begin Tuesday evening in Boston and taper by early afternoon Wednesday.

Blizzard-like conditions are expected in the southeast part of the state Tuesday night into Wednesday and arctic temperatures will grip much of the coastal area as another winter storm passes through the region, forecasters said.

Snowfall is expected to be the heaviest along the southern coastline, bringing 8 to 12 inches of snow and a blizzard watch to Cape Cod and coastal Plymouth areas, according to National Weather Service meteorologist Stephanie Dunten.

A winter warning has been issued for Eastern Massachusetts.

“For the Boston area, we’re looking at 6 to 10 inches,” said Dunten. The amount of snowfall could change as the storm continues to form and its path becomes clearer, she said.

Snowfall should begin Tuesday evening in Boston and taper by early afternoon Wednesday, though some light flurries could continue through the evening.

On Wednesday, the Cape and coastal Plymouth areas could see more snow than other regions.

“The other big concern is the strong wind gusts for that area,” Dunten said. The winds “will probably be between 30 to 40 miles per hour and could be even higher.”

With the intense gusts and blowing snow, visibility could be reduced to a quarter mile or less in the southern coastal region, she said.

Temperatures in the Cape region are expected to be in the high teens Tuesday night and then plunge Wednesday night, with a low of 9 degrees.

Boston will experience severe cold as well, with Tuesday’s temperatures expected to drop as low as 10 degrees, forecasters said. Highs are predicted to be about 18 degrees.

On the bright side, the snow is expected to be light in nature.

“It’s going to be powder,” Dunten said. “Not good snowman-making snow.”
