DAYS 1-5 (JANUARY 11-15)
I joked on the Woods Hill Weather Facebook page yesterday that it would be a “back to the 60s weekend”, referring to 2 days of high temperatures reaching or exceeding 60 degrees, and that indeed will be the case. I was concerned that a frontal boundary would slip down the coast from the northeast and change things up for some areas on Sunday, but that front will remain to the north and the boundary from the west will be charging east, eventually putting an end to the 2-day warm-up. Today will be a rain-free day, although you probably already have noticed damp surfaces starting yesterday and continuing today. This is due to the warmer, relatively humid air making contact with colder surfaces and the moisture condensing there. It’s the same process you see when you get water condensation on the outside of a cold glass of the beverage of your choice. So any wet ground today is not due to rain, but due to that. The only real rain threat comes in the form of numerous showers and possible thunderstorms Sunday morning, from west to east, as the cold front sweeps through. We’ll have to keep a close eye on this activity as winds not too far above the ground will be very strong, and any convective shower or thunderstorm activity can bring some of these winds down to the surface, potentially producing damaging gusts. It will remain breezy behind the front as it clears out rapidly by Sunday afternoon, and the temperature will go down, though this is not an arctic air mass invading so we won’t have one of those temperature nose-dives this time. After this goes by, high pressure shifts eastward through the Maritime Provinces of Canada and as a result a little weak easterly flow sets up here and may produce enough low level moisture for a few rain/snow showers on the Capes (Cod & Ann). The active pattern continues as then we will be impacted by 2 low pressure systems before this 5-day period is over, the first being a disjointed system with energy passing by both to the north and to the south of southeastern New England, setting up a risk of rain showers late-day and evening on Tuesday. The second system looks slightly more potent and should have a stronger low pressure area heading from the Ohio Valley and Great Lakes toward northern New England by Wednesday night, returning a chance of rain to the region.

DAYS 6-10 (JANUARY 16-20)
The storm system that arrives late Wednesday will exit at the start of this period with a rain shower risk early January 16 followed by wind and falling temperatures. Fair, colder January 17 setting up the potential for a winter storm of snow/mix/rain during the January 18-19 weekend, timing and details to be determined, followed by clearing and colder weather to end the period.
DAYS 11-15 (JANUARY 21-25)
The active weather pattern will continue with one or two precipitation threats and colder air around, so additional snow/mix will likely be involved with these threats.
