DAYS 1-5 (DECEMBER 31 – JANUARY 4)

The final day of 2025 will be less windy than the penultimate day of the year was, but it will be a cold one, with dry conditions. Expect some cloudiness to interrupt the sun at times with an approaching trough. This evening as we get set to welcome 2026, we’ll have clouds increasing as a clipper system rounds the bend of a trough moving in and somewhere toward and mainly after midnight, snow will break out across the region, resulting in some accumulation (least northwest, more to the southeast), but not a major event. This tapers off to snow showers as low pressure starts to redevelop just offshore and moves away prior to noon on New Year’s Day. From Thursday afternoon through the coming weekend, the story will be cold and dry weather as high pressure moves in and delivers an abundance of polar air. A storm system is likely to pass well south of our area on Sunday with a shield of high clouds filtering the sun.

TODAY: Variably cloudy. Highs 27-34. Wind W 5-15 MPH, gusts around 20 MPH.

TONIGHT: Becoming cloudy. Snow late evening / overnight – a coating to 2 inches except 2 to 4 inches southeastern MA and southern RI. Lows 14-21. Wind variable up to 10 MPH.

THURSDAY (NEW YEAR’S DAY): Partly sunny. Morning snow showers possible. Highs 24-31. Wind W to NW 10-20 MPH.

THURSDAY NIGHT: Partly cloudy. Lows 11-18. Wind NW 5-15 MPH, higher gusts.

FRIDAY: Partly cloudy. Highs 22-29. Wind NW 5-15 MPH, higher gusts.

FRIDAY NIGHT: Partly cloudy. Lows 11-18. Wind W 5-15 MPH.

SATURDAY: Mostly sunny. Highs 25-32. Wind W 5-15 MPH.

SATURDAY NIGHT: Mostly clear. Lows 11-18. Wind NW up to 10 MPH.

SUNDAY: Sun and high clouds. Highs 25-32. Wind NW up to 10 MPH.

DAYS 6-10 (JANUARY 5-9)

Watching January 5-6 for a clipper low potential. Later-period threat has trended to less of a threat with some uncertainty in the overall set-up. Temperatures mostly below normal, but may moderate late-period.

DAYS 11-15 (JANUARY 10-14)

Variable temperatures averaging around normal. While the pattern looks a little more active for precipitation, there are no strong indications of major storminess at this point.

  3. Thanks TK
    A little snow to ring in the New Year!
    Snowfall Standings on last day of the year
    NY 7.2
    BOS 4.3
    A chance for BOS to close the gap a little bit with the system tonight. This could change but it looks like NY will stay in the lead till mid January.

  4. Thank you TK!

    My thank you extends beyond your forecast for just today. It is really the thinking and work you put into the daily forecast for each day of the year. I have learned a lot from you about the weather. (Not excluding others who have contributed to my learnings.)

    Thank you again, Longshot.

  9. Thanks, TK.

    It’s quite the streak that Philip reminds us of every day. The periodic light snow events – reminiscent a bit of last year – remind us that it can snow. But the weather gods thus far won’t allow for heavy snow in Boston. It’s not a curse. It’s simply the way things have played out meteorologically.

    I do like the cold and sunny days, though.
