New England's light snow event will continue through much of the day today, bringing most an inch or two of snow as a clipper system fails to merge with a stronger coastal storm passing well to the south. A warm-up back to seasonable temperatures will continue through about midweek next week. Another clipper will likely scoot through the region Tuesday and Tuesday night, bringing more snow showers and a return to colder temperatures for later next week.
Widespread snow showers will continue through the morning for much of New England, pushing into central and eastern Maine by this afternoon. Snow will gradually taper off and become more scattered through the afternoon from west to east. Scattered snow showers will likely continue for eastern Massachusetts, New Hampshire and Maine through the evening hours, however, the bulk of what limited snow will fall will come through the early afternoon.

When the snow stops flying, most of New England will likely have seen a dusting to two inches of snow. The best chance to see three inches will come across northeast Massachusetts, southeast New Hampshire and southwest Maine. This will come as moisture will be slightly increased in these areas, leading to a more persistent snow that will last a bit longer.
This will be a light and fluffy snow with ratios around 15:1. This type of snow accumulates quickly, so the bump in moisture makes a difference for the coastal plain (mainly Boston to Portland) when it comes to accumulations as it will make it easier to see a bit more snow in this corridor. Overall, both moisture and lift will still remain on the meager side, keeping snowfall minimal across the board.
After this system, the break in the colder-than-average temperatures will likely last through the weekend and into Monday. Temperatures during this time will be more on the seasonable side rather than above average. High pressure builds in, keeping conditions calm and pleasant by mid-January standards.
Another weak clipper system will scoot by northern New England around Monday night to Tuesday night with some snow showers. This system doesn't look to be very organized. This is likely to result in scattered snow showers with minimal (if any) accumulations. The better chance for a bit of accumulation will be across the northern third of New England. The system may intensify in the Gulf of Maine, resulting in a shot of accumulating snow across Downeast Maine.
This system will swing the door back open for another shot of cold air heading into the middle part of next week as it creates a deep and strong northwesterly flow once again on its backside. Overall, next week's cold shot doesn't look as cold or windy this past week. It is also unlikely to last as long, either. There will likely be widespread highs in the 20s to low 30s around the middle to latter part of next week.

Heading toward next weekend, there are some signals of a modest warm-up, especially compared to how January has played out thus far. After being dominated by a northwest flow, a switch to a more southwest flow may develop. Any warm-up that does occur doesn't look to be major and guidance remains split on just how next weekend shakes out. This warm-up could be accompanied by some unsettled weather, but any details on that front are vague right now.
