Here is the timeline of the nor’easter and how it’s forecast to unfold in Southern New England and in Northern New England, including its arrival and length, according to the new models.
• Sunday morning to 2 p.m. — You should be able to enjoy Sunday morning if you have plans. Afternoon highs will reach the low 60s before the clouds build and cap off the heating for the day.
• Sunday, 2 p.m. to 7 p.m. — A few scattered, leading-edge showers push into Southern New England from the south. A couple of heavier showers begin to push into portions of Massachusetts, Rhode Island, and Connecticut later in this timeframe. Winds from the northeast between 10 and 20 mph and gusts as high as 40 mph, especially on the Cape, South Coast of Massachusetts, and coastal Rhode Island.
• Sunday night to Monday, 12 noon — As of immediately, this is when the heaviest of the rain will occur. Multiple pockets of steady to heavy rain will push into the region from the south. Boston, Providence, Worcester, and as far west as Springfield and Hartford could see heavy rain during this stretch. The heaviest bands of rain could spread across Southeastern Mass. and the Cape. Winds will continue to about 15 and 20 mph during this stretch, with gusts reaching as high as 40 to 60 mph, especially along the immediate coast.
• Monday afternoon to evening — Steady, widespread rain shifts to more broken pockets of precipitation. Some storm cells may release a heavy downpour at times, but this stretch sees some breaks in between the rainfall. By immediately, there will likely be near or more than 2 inches of rain for many folks east and south of Boston and Worcester. Expect broken showers to persist through Monday night as the storm stalls and weakens just to the south of New England. During this stretch, gusty winds continue with gusts reaching 30 to 50 mph.
• Tuesday — The stalled nor’easter breaks down and dissipates, but not before leaving some lingering scattered showers. The weather much improves as the low falls apart, but scattered showers will be light. Winds relax to 10 to 15 mph with some gusts reaching 20 mph. The storm wraps up by the end of the afternoon.

Most of New Hampshire, Vermont, and Maine will avoid the intensity of this nor’easter.
• Sunday 2 p.m. to 7 p.m. — Staying dry for the most part, even though skies turn mostly cloudy to completely overcast during this time. A few sprinkles may reach southern Vermont, New Hampshire, and Maine by the latter portion of this window. Wind speeds pick up, reaching 10 to 15 mph, with a few gusts near 20 to 25 mph.
• Sunday night to Monday at noon — Scattered showers progress north across the Northern New England states with some steady rain mixing in. By early Monday morning, a few pockets of heavier rain will progress into the region, but rain intensity won’t be as strong as what Southern New England will see. Wind gusts will reach 30 mph, especially near the coast.
• Monday afternoon to evening — Same as areas to the south, rainfall turns to more broken and scattered showers, but don’t be fooled, some pockets of rain will still hold heavy downpours. Windy conditions persist with a breeze of 10 to 15 mph and a few gusts reaching 30.
• Tuesday — The storm spins out of energy and dissipates rather quickly on Tuesday. Mostly cloudy skies with a breeze of about 10 to 15 mph, with a couple of light showers possible across each of the states.
