Two feet of snow could hit Massachusetts by early Tuesday

Ricardo Hernandez shoveled snow from the sidewalk along Boylston Street in Boston this past week. Another storm on tap could leave Mass. with up to two feet of snow by Tuesday.

Massachusetts is about to see a lot more snow — as much as two feet over the next two days — as a slow-moving storm front hangs over the state until early Tuesday morning, according to the National Weather Service in Taunton.“The storm is prolonged, rather than a classic nor’easter,” said meteorologist Bill Simpson of the weather service.  Two to 4 inches of snow fell Saturday night and is expected to be followed by an additional 4 to 8 inches Sunday. But during pre-dawn hours on Monday even more snow will fall, Simpson said. Heavy snow is expected to fall throughout the day, “unfortunately for both commutes,” Simpson said. By the time it ends, the on-again, off-again storm could leave 18 to 24 inches of snow from Boston up the North Shore and into the Merrimack Valley, according to the weather service. Much of the MetroWest area and Central Massachusetts could get 14 to 18 inches. The Cape and Islands could see some mixed snow continue into Tuesday. The storm is expected to leave the area by the early morning hours Tuesday. Coastal flooding in not expected to be a concern, Simpson said. A winter storm warning is in effect until 1 a.m. Tuesday. “At least this one’s just snow. [We’re] not looking really for wind damage or any coastal flooding this time,” he said. Temperatures could rise to about 30 degrees during the day on Monday and on Tuesday, though they are expected to drop to about 20 degrees Monday night, Dellicarpini said. Very cold air will hit the region on Thursday, with temperatures dropping into the single digits, Dellicarpini said. On Friday, the high temperature is expected to be around 15 degrees, dropping to zero in Boston and below zero in the suburbs on Friday night, he said. Those going outside should be sure to bundle up and keep all of their skin covered in the blistering cold, Simpson said. There is also a chance for more snowfall on Thursday, but that system could pass south of Greater Boston, Dellicarpini said. At Logan Airport, crews plan to work through the storm to keep runways open, unless the weather makes snow-removal unsafe, Massport announced Saturday afternoon. The agency encouraged passengers to contact their airlines to get updated information on the status of their flights. If conditions get bad enough, Massport said, the airport will work with airlines to provide cots to stranded passengers. Out on the streets, fire officials are asking residents to make sure the areas around their closest hydrants are clear of snow. While members of local fire departments will clear out the hydrants after and possibly during the storm, “if you’re physically able, don’t wait for us,” said Chelsea Fire Department Deputy Chief Robert Zalewski. Early Saturday morning, firefighters rescued a woman from a fire in her bedroom at the top of a three-story house in Chelsea, Zalewski said. The hydrants near the house were all cleared, and the home had working smoke detectors, so the fire was knocked down in about 30 minutes. More
