It’s not over yet, and this time Boston is in for it. Sort of.
The long-duration storm that arrived on Sunday churned over Massachusetts on Monday, and won’t be gone until midday Tuesday, the National Weather Service has projected.
The storm Sunday night left a foot or more of snow in some areas of Massachusetts, particularly in northern and western parts. Methuen saw 13 inches, while the northwest corner of the state saw as much as 16 inches. MetroWest towns like Hopkinton and Wayland saw between 8 and 9 inches, while much of the eastern coast — including Boston — didn’t see much in terms of accumulation, according to snow totals from the National Weather Service.
However, Eastern Massachusetts could be in for a doozy Tuesday morning. While a messy wintry mix fell on Monday, the second wave of snowfall is expected to begin around 4 a.m. Tuesday and end sometime in the early afternoon, with the heaviest snow expected to fall 4 a.m. to 10 a.m. in the eastern part of the state, including Boston.
There is some uncertainty on the storm track, forecasters said — if it tracks father offshore, then the snow totals will be lower; if it tracks closer, then there will be higher totals. Either way, forecasters say there is the potential for a “significant impact” to the morning commute.

The storm is expected to drop 4-6 inches of snow on Boston by Tuesday afternoon, forecasters predicted Monday evening. However, some of the southern parts of the state, including the Cape and Islands, are likely to see only 1 to 2 inches of accumulation — or even none at all.
When the expected accumulation is broken down by range, Boston is expected to see 6 to 8 inches.
On the high end of the spectrum, there is a slight chance that Boston could receive 10 inches of snow, according to Monday evening projections of the storm.
However, on the low end of the range, there is also a slight chance Boston could see just 3 inches of snow.
But those who hate to shovel shouldn’t get their hopes too high: There’s a 67 percent chance that Boston could see 4 inches or more of the cold white stuff.
But for those rooting for piles of snow in the city, just be warned: There’s only a 3 percent chance that Boston will see 8 inches or more.
The weather service also has compiled a handy chart to show how many inches are expected in each area, and the percent chance for those totals.
Much of Eastern Massachusetts is under a winter storm warning until noon Tuesday — including communities like Boston, Quincy, Gloucester, Foxborough, and Framingham — meaning that travel will likely become very difficult, according to the weather service. Much of the rest of Massachusetts is under a winter weather advisory.
“Plan on slippery road conditions. The hazardous conditions will likely impact the evening and morning commutes,” forecasters said.
North of Massachusetts, much of Sunday’s snowfall accumulated near the border with the Bay State.
“Many locations haven’t seen accumulations yet,” forecasters in Gray, Maine, said Monday. “The second round is expected to bring significant snowfall from the midcoast area south into New Hampshire overnight and into tomorrow morning.”
Gusty winds, resulting in reduced visibility, could accompany snow along the coast on Tuesday morning, forecasters said in a separate tweet.
