The first "bread, milk and eggs alert" of the winter could be blared across the Bay State later this week.

Forecasters are tracking a nor'easter that could dump several inches of snow across the state from Thursday night into Friday.

Boston's initial forecast for snow totals is 4 to 6 inches, but that could definitely change over the next few days.

"There's still a lot of uncertainty in the exact track of the system," said Bill Leatham, meteorologist at the National Weather Service's Boston office.

The forecasters are trying to determine how far west the system will track, which will impact the specific snowfall amounts for the region.

"In New England, we're no strangers to getting wintry weather, but folks will want to stay tuned to the forecast if they're traveling," Leatham said. "It could be a slick commute on Friday.

"We'll get a better idea on how much snow we'll get as we get closer to Thursday," he added.

Forecasters expect a low-pressure system to develop off of the mid-Atlantic coast on Thursday.

"This coastal low will track northeastward toward southern New England Thursday night into Friday bringing the potential for significant snowfall," states the National Weather Service forecast discussion. "There is still considerable uncertainty with respect to the track of this storm, thus there is also uncertainty in which areas will see snow (or potentially rain) and how much snow will accumulate."

One forecast model shows that the "bullseye" of the storm's highest accumulations would be over the Interstate 95 corridor.

Another forecast model has the system tracking a bit further north and west, placing the heaviest snowfall over western Massachusetts and southern New Hampshire.
