The NBC Boston Early Warning Weather team has issued an Early Warning Weather Alert through Wednesday morning at 8 a.m.
Snow is expected to develop from southwest to northeast across Southern New England Tuesday midday through afternoon, reaching Connecticut during the late morning, Central Massachusetts and Cape Cod around midday and Boston to the Merrimack Valley during the early afternoon.
Some schools in Massachusetts and Connecticut have already announced early dismissals on Tuesday due to the approaching storm.
As of 1 p.m., snow was already beginning to fall in southwestern Massachusetts, spreading north for the evening commute.
Though intensity will mostly be light to moderate, snow falling onto subfreezing road surfaces this evening likely will make for some slick spots – particularly away from any chemically pretreated interstates.
Police in some Massachusetts communities - including Ashland, Wellesley and Worcester - are already responding to crashes as the roads start to ice up. Rhode Island State Police said they handled 55 accidents between 1 and 7 p.m. No serious injuries were reported.
The Massachusetts Department of Transportation is urging motorists to use caution, reduce speeds and stay a safe distance away from plows, especially seeing as 13 state plows have been struck by vehicles already this winter.
With the upcoming weather, it’s important to remember that safety is the greatest priority and we advise all travelers to minimize distractions, give themselves extra time and space, and don’t crowd the plow," MassDOT Highway Administrator Thomas J. Tinlin said.
Snow continues overnight Tuesday night, slowly drifiting northward overnight Tuesday night, tapering early Wednesday morning in most of Southern New England.
Bursts of snow will continue in Northern New England on Wednesday, likely heaviest near Penobscot Bay in Maine.
By the time all is said and done, about four inches falls in much of Southern New England with locally higher amounts in Southern Worcester County, near Cape Ann in Eastern Massachusetts, along the Berkshires and Green Mountains, and near Penobscot Bay in Maine.
