Although Monday is a breather with bright and brisk conditions, save for Cape Cod where stubborn clouds linger on the north side of an ocean storm missing New England to the south, the weather pattern is about to turn more active and changeable.
As soon as overnight Monday night into Tuesday morning, an onshore flow develops, meaning a wind off the ocean, adding moisture to a cold airmass, which often can produce ocean-effect snow showers and likely will again this time around.
The result of ocean-effect snow showers into Tuesday morning will be at least some slick spots developing for the Tuesday morning commute before the impact of daylight and slowly rising temperatures, along with a slowly northward-moving and diminishing area of flurries, brings an end to slick conditions.

Later Tuesday, our next storm approaches from the west, triggering snow showers in Northern and Western New England first, then expanding east Tuesday evening and night, with a rain/snow line somewhere near the Route 495 corridor in Eastern Massachusetts.
For Western and Northern New England, snow Tuesday night into very early Wednesday morning will add up to 6 to 12 inches, but amounts will be far less within 30 to 50 miles of the coast, with very little accumulation at all in Southeastern New England.
The storm quickly departs, for most by Wednesday dawn, and although sun breaks out for much of the day, an afternoon arctic front will trigger some snow squalls on the leading edge of a cold blast that will send temperatures and wind chill values below zero Wednesday night, and hold wind chills below zero on Thursday.
Our exclusive First Alert 10-day forecast shows us rebounding from the cold pretty quickly through the weekend, with exceptionally mild air possible next week.
