DAYS 1-5 (NOVEMBER 6-10)
High pressure provides a nice early November day today. A cold front approaches Thursday with clouds and eventually wet weather, though that may hold off until very late in the day. The front slides through at night as a wave of low pressure develops on it and moves across the region, intensifying after it moves away. As cold air is pulled in, it becomes cold enough to start supporting snow instead of rain north and west of Boston but this will also take place as drier air moves in and the precipitation ends, so brief snow is really all that possible in those areas, so a “worst case” scenario would only produce a minor accumulation at higher elevations of north central MA and southwestern NH that would melt shortly after it fell as the ground is still on the warmer side for holding onto any snow. However, Friday itself will be a windy and cold day, feeling more like early winter. The chill will continue through Saturday but with less wind, so other than a very cold morning, the daytime will feel less cold than Friday. A little more temperature moderation will occur Sunday with a southwesterly air flow ahead of another approaching cold front, but initially this front will be moisture-starved, so only a few clouds are expected to move in during Sunday.

DAYS 6-10 (NOVEMBER 11-15)
A front will be nearby, probably just to the south, November 11 (Veterans Day) so expect some cloudiness and cool conditions. From the night of November 11 into November 13 waves of low pressure will travel along that boundary south of the region with cloud cover and occasional precipitation in the form of rain and/or snow, depending on location. Not looking for a large winter storm type event, however. Drier weather arrives thereafter as high pressure pushes in but a disturbance may bring a rain shower risk around November 15 with milder air briefly.
DAYS 11-15 (NOVEMBER 16-20)
We may eventually need to watch a boundary to the south for the threat of unsettled weather but for now looking for high pressure to be dominant with mainly dry weather during this period, starting colder than average then moderating.
