DAYS 1-5 (DECEMBER 27-31)

High pressure hangs on with fair weather today. Three unsettled days follow. A warm front approaches Saturday bringing clouds and a period of light rain during the morning to midday hours. However, with temperatures below freezing in many inland locations, especially north of I-90 and west of the I-95 belt, there will be patches of icing as a result. The warm front itself may take until sometime Sunday to pass through the region, and while any additional precipitation will be limited, some drizzle can occur, and this will be with inland temperatures still near to slightly below freezing for a while. Eventually all areas rise above freezing by sometime Sunday and thus the icing threat ends, but some additional rain can occur under a cloudy sky. Another ribbon of rain will move through the region Sunday night into Monday morning with the passage of a cold front, trailing low pressure passing to our north. Drier air arrives during Monday afternoon with improving weather, which will last into New Year’s Eve on Tuesday with a weak area of high pressure moving in for the final day of 2024.

TODAY: Sunshine. Highs 35-42. Wind variable under 10 MPH.

TONIGHT: Clouds increase. Lows 24-31. Wind variable under 10 MPH.

SATURDAY: Cloudy. A period of light rain with icing inland locations morning to midday. Patchy drizzle with freezing drizzle inland thereafter. Highs 30-37, coldest interior locations north of I-90 and west of I-95. Wind calm through midday then SE up to 10 MPH.

SATURDAY NIGHT / SUNDAY: Cloudy. Periodic rain and drizzle. Additional icing at first inland locations mainly well northwest of Boston. Areas of fog. Temperatures slowly rise to 40-47. Wind SE 5-15 MPH.

SUNDAY NIGHT: Overcast. Areas of fog. Rain likely. Temperatures rise slightly to 46-53. Wind SE 5-15 MPH with higher gusts.

MONDAY: Overcast with areas of fog and rain likely morning-midday. Breaking clouds later in the day. Highs 48-55. Wind SE 5-15 MPH with higher gusts, shifting to SW.

MONDAY NIGHT: Partly cloudy. Lows 31-38. Wind W 5-15 MPH.

TUESDAY: Partly sunny. Highs 41-48. Wind W 5-15 MPH.

DAYS 6-10 (JANUARY 1-5)

Low pressure brings a rain chance for the first day of 2025 (may be some inland mix with borderline temps). Drier, colder weather follows.

DAYS 11-15 (JANUARY 6-10)

Winter storm potential early in the period, followed by fair weather. Overall pattern is colder.

  4. Both the GFS and EURO are now advertising some decent snows
    down the road. TOO EARLY to post maps. Just something to keep and eye on. 🙂

  5. Thanks, TK.

    Dense fog this morning. I heard an English woman tell her child “it’s very foggy,” which of course is an understatement. Visibility was down to around 50 feet early this morning. It’s now perhaps at 125 feet. I could not see across the width of the football pitch on my 10am jog.

    As always, relatively `mild,’ but because of the dampness it feels raw everywhere, including indoors. No frost in sight, though. My daughter says they’ve had two nights in which it dipped below freezing, to 31F. Other than that, it’s been a steady diet of 48F for a high and 42F for a low, overcast skies and lots of nothingness. The British Met Office calls this “settled” weather. Indeed, it’s about as settled as it can be. Nothing is happening.

    The fields and paths are very muddy. There’s no sun to dry out anything. Plus, the black, clay-like soil is dense and not porous like ours. Any moisture, whether rain or simply from the low-lying clouds, just sits on top of the ground and doesn’t go anywhere.

      1. It’s awful, I lived there for 4 years and the winters were simply miserable.

        FYI still looking at a get together in Jan/Feb, let me know if you are interested, shoot me an email at hkasrawi@gmail.com

  7. By far, the thickest frost of the season.

    In spots the sun hasn’t hit yet, it looks like a feather dusting of snow.

  11. From nws

    [Light Icing Saturday] A light freezing rain event moves in for Saturday AM in interior Southern New England. Hazardous travel conditions due to icy roads are possible Saturday AM into early PM. Winter Weather Advisories are now posted for areas north and west of I-95:

  14. Thanks TK.

    Incredible temperature inversion on Mt Washington this morning. Don’t think I’ve ever seen anything so extreme. Look at the temp change over just 2400′ between Pinkham Notch and the elevation of Tuckerman’s Ravine!

      1. Canadian is further SE though as well with the secondary low on 1/1 now tracking SE of us. This is at least good news for the ski areas as this should lock in the colder air up north and keep this a snow event after the warm system on 12/29-30. They should recover from that just fine.

        Unfortunately we are heading up to my mother’s in Upstate NY on Sunday and have a two day window to get some cross country and/or downhill skiing in on Monday and Tuesday. I am afraid the rain Sunday night is going to do a number on the snow conditions although it should be in and out quickly. Just bad timing.

    1. The 1/1 event will be mainly rain in the majority of the WHW forecast area.

      The pattern improves after that.

  17. 12z Euro coastal redevelopment too late to even save NNE on 1/1…

    But has this absolute bomb for 1/7:

    Verbatim snow to rain for SNE on that run with 1-2+ feet in CNE/NNE. But ensemble mean is SE of the operational.

    That ~1/7-1/9 timeframe is really going to be a period to watch. Great overall setup on all the models in that timeframe.

  20. Thanks, TK!

    My Vanderbilt Commodores play Georgia Tech in the Birmingham Bowl starting in about 10 minutes. This is only the 10th time in school history that Vandy has gone to a bowl game and the Commodores have only won four of those bowl games.

    Go ‘Dores! Anchor Down!

  21. 17 out of 26 days (so far) in December have had a negative temperature departure at Boston. For the month-to-date, they’re at -2.4F for a departure from long term average.

    With a slight moderation as we head through the last few days of the month, they’ll probably land around -1.5F or -2.0F departure, as I had discussed about a week or so ago. No changes to that thinking.

    1. I’m going to root for a weaker, more progressive system. My son is driving back from NJ that day.
