Boston area could see 6 to 10 inches of snow

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 southern New England.

“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.

On Wednesday, the Cape and coastal Plymouth areas could see more snow than other areas “due to ocean enhancement,” said Dunten.

“The other big concern is the strong wind gusts for that area,” she said. “[The winds] will probably be between 30 to 40 mph and could be even higher.”

With the intense gales and blowing snow, visibility could be reduced to a quarter mile or less in the southern coastal region, Dunten 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.”

The snow should taper by early afternoon in Boston Wednesday, though some light flurries could continue through the evening. Skies will be mostly sunny with highs near 17 degrees. Clouds will move in overnight as temperatures sink to 5 degrees.

A wind chill advisory could be issued Wednesday night as a combination of blustery winds and cold air will make the wind chill drop to minus 15 to minus 20 degrees before Thursday morning.

“The coldest temperatures will probably be Wednesday and Thursday morning, but Friday morning we start moderating slightly,” said Bill Simpson, a meteorologist for the National Weather Service.

Skies should be sunny and dry Thursday, with highs in the upper teens. Clouds should move in during the evening as temperatures drop to 5 degrees.

Friday will be similar, with sunny skies and highs near 20 degrees. The evening should become cloudy as temperatures drop to 13 degrees.
