A potent frontal system will deliver rain and snow across New England Sunday evening and last through at least Monday morning. With a warm front moving east from the system, Boston will stick to rain through Sunday night, while widespread accumulating snow is expected across Northern New England, prompting winter weather alerts for that region. Folks up north will be forced to break out the shovels and snowblowers for hopefully one last time.
But by the time we start heading out the door on Monday, the rain-snow line will have sunk farther south and bring some snowfall into most of Massachusetts, including Greater Boston, along the Mass Pike, and west through the Berkshires. The South Shore and coast should stick to a light wintry mix or rain.
All in all, it looks like Boston could pick up about an inch of snow, mainly during the predawn hours of Monday. If Logan Airport ends up with an inch, it would be the latest date in the season since 2007. Folks across northern Worcester and Berkshire counties may see 1 or 2 inches, while the jackpot totals for this storm are held to extreme Northern New England. Roads will be wet early Monday, so take it slow during the morning commute.
Monday afternoon: Blustery, scattered snow showers
Scattered snow showers will linger over most of New England on Monday after the bulk of the precipitation moves offshore by late morning, keeping the day pretty unsettled under mostly cloudy skies.
Monday will remain blustery with the storm strengthening as it pulls away from New England. Wind gusts will hover around 20 mph throughout most of the day, not enough for power outage concerns, but enough to feel the wind push through your jacket.
With cold air settling in behind the passing system, Monday’s highs will be held to the 30s across most of New England. But when you pair the breeze with the cold air, most of the day will feel subfreezing, with wind chills in the 20s from sunrise to sunset.
The sun sets at 7 p.m., Monday as our days get longer.
