DAYS 1-5 (JANUARY 6-10)
Lots of weather to track. Let’s get to it. First we have a low pressure area moving across the northern Great Lakes and southern Canada, with a trough extending down into New England today, and this may produce a touch of light snow at times except light rain Cape Cod area where it will be too mild for snow. This will be an insignificant system with no travel impact. A slightly stronger low will track rapidly eastward, passing south of the region late Tuesday and early Wednesday, and may produce a minor snow event mainly south of I-90, most of it occurring Tuesday night. Behind this system on Wednesday may come a few snow showers but more importantly will be colder air and a gusty wind. As high pressure drifts across the region Thursday it will be a cold but more tranquil day. But this high will be offshore by Friday and a warm front will move across the region with more cloudiness and some spotty light rain (and some interior area sleet) possible. Forecast details…
TODAY: Mostly cloudy. Spotty light snow (brief dustings at most) at times except light rain Cape Cod. Highs 30-37. Wind S under 10 MPH.

DAYS 6-10 (JANUARY 11-15)
The weekend of January 11-12 starts very mild and ends much colder, with a transition from one to the other taking place as a frontal boundary and wave of low pressure bring mostly rain, which may end as mix/snow for northern and western areas. Fine tuning to come. Drier/colder interlude will be followed by moderating temperatures and more unsettled weather later in the period.
DAYS 11-15 (JANUARY 16-20)
A similar pattern, active weather, up and down temperatures, currently impossible to detail.
