DAYS 1-5 (JANUARY 7-11)
A small, fast-moving, but intensifying low pressure area forming in the Mid Atlantic will track off the coast and pass just southeast of New England tonight and early Wednesday, producing a mini snowstorm for southeastern New England before exiting. In its wake, a shot of cold air will arrive, perhaps with some additional snow showers Wednesday, and it will be quite cold for Thursday. Although as has been the characteristic of early winter, this cold shot will be short-lived, and moderating temperatures will already be felt by Friday, leading to a rather warm Saturday as low pressure tracks through the Great Lakes to the St. Lawrence Valley and we end up in a moderate to strong southwesterly air flow. We may see a touch of light rain and sleet early Friday as a warm front passes, and then our warmer air arrives. A cold front will try to approach on Saturday but will be held at bay initially by strong high pressure offshore, and that may also keep rain chances down as well, keeping the wet weather mostly west and north of the region to start the weekend.
TODAY: Sunshine followed by increasing clouds. Highs 33-40. Wind W up to 10 MPH.
TONIGHT: Cloudy. Snow arrives late evening from southwest to northeast but may start as rain/mix Cape Cod, steadiest overnight I-95 southeastward. Lows 25-32. Wind E 5-15 MPH near the South Coast, variable under 10 MPH elsewhere.
WEDNESDAY: Cloudy with snow early morning, especially I-95 southeast, ending mid morning with accumulation a coating to 1 inch NW of I-95 and 1-3 inches from near I-95 southeastward. Clearing late morning. Sunny afternoon. Highs 32-39. Wind NW increasing to 15-25 MPH with gusts 30-40 MPH.
WEDNESDAY NIGHT: Clear. Lows 15-22. Wind NW 10-20 MPH with higher gusts, diminishing overnight.
THURSDAY: Sunshine and high clouds. Highs 25-32. Wind variable up to 10 MPH.
THURSDAY NIGHT: Increasing clouds. Lows 18-25 evening, rising slowly overnight. Wind SE under 10 MPH.
FRIDAY: Mostly cloudy. Scattered light rain, possibly some sleet interior areas, favoring the morning hours. Highs 40-47. Wind SE under 10 MPH shifting to SW up to 10 MPH.
FRIDAY NIGHT: Mostly cloudy. Temperatures steady 40-47 evening, rising to 50-57 overnight. Wind SW 5-15 MPH, higher gusts.
SATURDAY: Variably cloudy. Risk of a passing rain shower. Highs 55-62. Wind SW 10-20 MPH, higher gusts.
DAYS 6-10 (JANUARY 12-16)
January 12 starts mild with rain then turns sharply colder with rain possibly ending as sleet and/or snow in some locations as the cold front held to the northwest earlier in the weekend moves through. Brief dry, colder weather January 13 then 1 or 2 additional low pressure areas may impact the region middle to end of this period with more unsettled weather.
DAYS 11-15 (JANUARY 17-21)
Still looking at a similar pattern of active weather, probably needing to watch 1 or 2 additional low pressure systems bringing precipitation threats. Far too soon for detail.
