A pair of storm systems will impact our weather over the next few days, but mostly with rain, not snow.
High pressure will slide off to the east tonight, with winds shifting into the southwest, bringing some milder air in. Friday will be relatively mild (by January standards), but clouds will be streaming in ahead of a low pressure system headed for the Great Lakes. As that system moves into Quebec some showers are likely ahead of it Friday evening before a cold front moves through overnight. That front will stall out south of New England allowing some cooler air to move back in. Meanwhile, another low pressure system will head towards the Great Lakes, trying to bring that front back northward as a warm front. As that system moves into Ontario, a secondary low pressure system will develop off the Mid-Atlantic coastline., preventing that warm front from moving in, and giving the new low pressure area a path eastward. This will bring more substantial and widespread rain in for late Saturday into Sunday morning. However, with the cold air in place, precipitation may start as some sleet or freezing rain well north and west of Boston, mainly interior southern New Hampshire and northern Worcester County, as the rain moves in later Saturday. A few additional rain or snow showers in the afternoon as an upper-level low pressure area crosses the Northeast, then high pressure builds in for Monday with cooler and drier conditions. For the Patriots game Sunday evening, it should be mostly cloudy at kickoff, winds out of the northwest at 5-10 mph, with a game time temperature around 37, dropping into the lower 30s by the end of the game.
Thursday night: Becoming partly to mostly cloudy. Low 22-29.
Friday: More clouds than sun, becoming breezy in the afternoon, showers possible towards evening. High 41-48.
Friday night: Cloudy with showers likely, mainly before midnight. Temperatures continue to rise until midnight, then drop to 33-40 by daybreak.
Saturday: Mostly cloudy with rain developing from southwest to northeast, possibly starting as some sleet or freezing rain well north and west of Boston. High 40-47.
Saturday night: Any mixed precipitation changes to all well rain north and west of Boston, periods of rain elsewhere. Low 33-40.
Sunday: Rain ends by midday, mostly cloudy with a few more rain or snow showers possible late in the day. High 38-45.
Sunday night: Gradual clearing, breezy. Low 23-30.
Monday: Partly to mostly sunny, breezy. High 32-39.
