The wind will diminish under clear skies Saturday night, and the temperature will tumble through the teens into the mid to upper single digits by dawn on Sunday. After a sunny start, clouds will increase on Sunday. There will be a light wind and it will stay cold, with highs in the mid to upper 20s.
Clouds will thicken Sunday evening, and snow will develop shortly after midnight. Snow is likely for the rest of the night, and a few inches could accumulate by the end of the morning commute. Snowfall rates of 1″ per hour are possible during the morning commute. The temperature will be in the teens when the snow starts, then rise into the 20s by dawn.
The exact track of the storm is questionable, and that track will make a huge difference between receiving a half-foot of snow and closer to a foot of snow. The trend on Saturday was for the storm to track closer to the coast, pushing the higher snow totals inland, with some mixed precipitation likely near the coast. There is still time for the track to wiggle north or south, and the heavy snow could be pushed farther inland or dragged closer to the coast. We think the best chance of getting buried is in Northern RI and Central MA. Snow, mixed precipitation, and possibly some rain at the immediate coast will continue through Monday, ending as snow Monday mid to late in the evening.
It will be breezy to windy near the coast, but damaging wind gusts are not expected. The winds will increase as the storm departs, and the temperature will plummet Monday night. It will be in the single digits near the coast, and below zero inland by dawn. Wind chills may be -10 to -20.
The weather looks fairly quiet, and cold, in the middle of next week. A few snow showers are possible Wednesday and/or Thursday, and highs will be in the 20s to 30s.
