The National Weather Service office in Norton issued a revised forecast model Friday with some snowy news for Boston and Providence.
On Thursday, the Weather Service had reported that up to a foot of snow could fall over Western and Central Massachusetts.
The Weather Service on Friday said that Boston and Providence, while not slated to get a foot, could still receive “heavy snow” over the weekend.
“Latest trends suggest heavy snow may also fall in Boston to Providence corridor and possibly southeast MA,” the National Weather Service’s Norton office wrote in a post to X, formerly known as Twitter.
Dashed lines surrounding the Connecticut, Rhode Island and Massachusetts coasts and encompassing New Haven, Providence, Boston and much of southeastern Massachusetts outside the Cape and Islands indicated the area the Weather Service said it was most uncertain about.
The vast majority of Massachusetts — from the Berkshires as far east as Lawrence and Waltham — is slated for a solid 8 to 12 inches of snow, the Weather Service predicts.
A winter storm watch remains in effect for much of Massachusetts, Rhode Island and Connecticut from Saturday afternoon through late Sunday night.
The storm watch covers the areas surrounding the municipalities of Hartford, Windsor Locks, Union, Vernon, Putnam, Willimantic in Connecticut; Charlemont, Greenfield, Orange, Barre, Fitchburg, Framingham, Lowell, Lawrence, Gloucester, Chesterfield, Blandford, Amherst, Northampton, Springfield, Milford, Worcester, Foxborough, Norwood, Cambridge, Ayer in Massachusetts and Foster, Smithfield, Coventry, and West Greenwich in Rhode Island.
The Weather Service predicts total snow accumulations of between 6 and 12 inches in those areas and wind gusts of up to 40 mph.
“Travel could be very difficult,” the storm watch said. “Snow loading from heavy wet snow may lead to power outages.”
The Weather Service added that there was still uncertainty in aspects of the forecast and that some changes may be expected.
