EAST BOSTON, Mass. –

We have two more chances for more snow and several very cold days before Santa arrives in Massachusetts.

The storm, which brought up to 5 inches of snow to some parts of Massachusetts on Friday and challenged travelers, will hang over Halifax on Saturday morning. Behind it, StormTeam 5 meteorologist Mike Wankum said cold air will move into our area.

Saturday will be partly cloudy with a chance of temporary thunderstorms. Temperatures will be just a few degrees below freezing, so some melting will occur.

“The cold really sets in on Sunday and Monday,” said Wankum. “Even if we recover, it will take a while to get back to average, which should be around 40 degrees this time of year.”

Sunday morning also brings gusty winds. Wankum said wind chills will be below zero in most of the region.

From Monday these winds will subside and temperatures will slowly begin to rise again.

“There’s a system out here in the West that’s coming in and bringing some milder air with it. And depending on what time this comes through, we could actually see a little bit of snow on Christmas Eve,” Wankum said.

With this storm, timing will determine whether precipitation falls as snow or a wintry mix.

“If it comes through at 6 a.m., it’s cold enough to snow. If it slows down and comes in later, it will warm up too much and it will become more of a wintry mix and everything else,” Wankum said.

According to Wankum, if the timing works out, we could expect one to two centimeters of snow in large parts of the region.
