After dawning with sub-zero temperatures in some parts of New England, Sunday will end with snow.
Clouds will increase during the day, but it takes until after dinner for the first snow showers to break out in our area.
The snow will become more widespread and steadier after 9 or 10 p.m. in particular, with accumulation continuing overnight.
As early as midnight, however, slightly milder will begin creeping up from the south. That will switch the precipitation over to rain in coastal Connecticut, Southern Rhode Island, and on the South Coast of Massachusetts along with the Cape and Islands.
According to officials in the Massachusetts Department of Transportation (MassDOT), the timing of the storm will make Monday morning’s commute difficult.
In a weather advisory statement released today MassDOT advises travelers to, “plan ahead for the Monday morning commute because of snow moving into the state this afternoon and continuing in some areas into mid-day tomorrow.”
And it's not just drivers that will be affected. Boston Logan Airport has been experienceing weather related flight delays and is advising all passengers to check in with airlines for updates.
By 4-6 a.m. the rain snow line will continue to work northward, reaching the Massachusetts Turnpike. At that point areas south of the Pike will see primarily rain with snow and a bit of an icy mix to the north.
That trend continues into the 9 a.m. hour, with mostly rain in Southern New England, excluding in the highest terrain of Western Massachusetts where snow and a mix persists. Parts of far Northern Worcester County may also hold on to a mix a bit longer. It will be wintry in Vermont and away from the coast in both New Hampshire and Maine as well.
The precipitation will wind down during the afternoon, but it will be windy at the coast. Gusts will exceed 40 mph at times.
Final accumulations, before the switch to rain, still look to be a dusting-1” for the Connecticut coast, Southern Rhode Island, and far Southeastern Massachusetts.
More like an inch or two can be expected from Central Connecticut right up into the Boston area. That includes the South Shore, North Shore, and the immediate coast in New Hampshire and Southern Maine.
2-4” is expected in Northwestern Connecticut, much of Central Massachusetts, Metro-West, the Merrimack Valley, and much of the Maine coast.
4-6” will fall from Northern Worcester County into parts of the hilly terrain in Western Massachusetts, as well as in much of New Hampshire away from the coast.
6-8” amounts are likely in a swath from Central New Hampshire into Central Maine.
“Everyone’s trip to work, school and other destinations will be longer tomorrow morning,” said Highway Administrator Thomas J. Tinlin. "If people can stay home they should. If they have to go out, they should build more time into their commute; consider using mass transit or else travel later in the morning when temperatures rise and wet snow turns to rain. As always, this winter weather should be taken seriously so people can stay safe and avoid situations that place themselves at risk.”
