A storm will move through eastern Canada on Tuesday, so the southern edge of the precipitation will make a swipe at northern portions of the Northeast. Rain showers are forecast across central and upstate New York, as well as in northern Vermont and New Hampshire. In the higher elevations of these areas, it will be a light snow that falls due to the colder air. In northern Maine, there will also be widespread light snow throughout the day Tuesday. Some of this rain will work south and east into parts of Massachusetts and Maine during the evening hours before winding down overnight as the storm over Canada moves farther east.
Behind this system will be the return of colder air, and therefore the chance for some lake-effect snow on Wednesday. The threat isn’t looking too significant, so snowfall totals will be light for the most part. Snow showers may also develop in northern Vermont and New Hampshire.
