DAYS 1-5 (DECEMBER 3-7)

Today’s caution is to watch for icy untreated surfaces in areas where temperatures are near or below freezing at the surface. This will ease up as it climbs above freezing and much drier air and a gusty breeze is present today, resulting in melting / sublimation. Patchy clouds (from departing upper low) and fair weather (from approaching high pressure) will be around today. Thursday’s weather will be mainly fair, but watch for a line or cluster or two of snow showers and potential heavier snow squalls between mid afternoon and early evening – northwest to southeast – associated with an arctic cold front passing through the region. Any heavier snow showers / squalls can rapidly but briefly reduce visibility and produce a quick coating of snow that can lead to hazardous travel. This front ushers in a very cold air mass for Thursday night and Friday, but it doesn’t hang around too long as the core passes quickly. Low pressure passes well south of our region Friday night and Saturday morning with a shot at a little light snowfall, but this looks rather insignificant. A small high pressure builds in with fair weather Saturday afternoon into Sunday, before yet another strong cold front brings a snow shower chance later Sunday.

TODAY: Partly to mostly sunny. Highs 35-42. Wind NW 5-15 MPH, higher gusts.

TONIGHT: Mostly clear. Lows 23-30. Wind SW 5-15 MPH.

THURSDAY: Partly sunny. A late-day snow shower or snow squall potential north and west of Boston. Highs 37-44. Wind SW 10-20 MPH.

THURSDAY NIGHT: Partly cloudy early with an evening snow shower potential Boston area south. Clearing after. Lows 8-15. Wind NW 5-15 MPH, higher gusts. Wind chill approaches 0.

FRIDAY: Mostly sunny. Highs 23-30. Wind NW 5-15 MPH, higher gusts. Wind chill often below 20.

FRIDAY NIGHT: Mostly cloudy. Chance of light snow. Lows 15-22 evening, but may rise slightly overnight. Wind variable under 10 MPH.

SATURDAY: Variably cloudy. Chance of light snow in the morning. Highs 34-41. Wind variable up to 10 MPH becoming W.

SATURDAY NIGHT: Mostly clear. Lows 18-25. Wind W up to 10 MPH becoming calm.

SUNDAY: Partly cloudy. Chance of late-day snow showers. Highs 35-42. Wind SW 5-15 MPH.

DAYS 6-10 (DECEMBER 8-12)

Trend is fairly dry with below normal temps overall. A minor system can bring some precipitation mid period, but looks like a brief and insignificant event.

DAYS 11-15 (DECEMBER 13-17)

One or two precipitation threats in this period with a little more up-and-down temp swings, can include a brief but notable warm-up.

  1. Good morning and thank you TK.

    32 now and low for the night.

    Ocean: 49

    Light dusting of snow after changeover around 11:15 last night.

    Wordle: FAIL
    4 letters, 3 in correct position after 3rd guess led to a guess fest guesses 4, 5 and 6 with all valid words, but not to Wordle”s liking. The correct word was the one I didn’t choose. The other 3 came to mind first.

  2. Thanks TK !

    JpDave, I noticed Logan reported a few hrs of light snow overnight, though the visibilities were down to 4 miles only, but hopefully enough that you got a little something.

    Back on the wordle train: 3

    3. Ground dusted white here this morning. 🙂

      TOOK FOREVER for the changeover last night. By the time it changed, there wasn’t much left, that’s for sure!!!

  4. Full moon tomorrow night.

    Its got the king tides, especially the day-time high tides.

    I can see on some webcams, a very high tide already with an hour to go and, while no surge, there are some large waves left over from last night’s storm, so there will be some splash over, I would think.

  6. So, it was an interesting Wordle experience for me.

    My 1st guess netted me 3 letters all in the wrong spot.

    But based on what the letters were, I used my 2nd guess to try to uncover what I thought might be 1 or 2 of the other letters without using the 3 letters I got in guess 1 and luckily, it uncovered the other 2, in the wrong spot. So, I had all 5 letters discovered, in the wrong spot, after 2 guesses and got lucky to unscramble them correctly on the 3rd guess.

  7. Thank you TK. 28 now a high of 34 yesterday and a good part of early am.

    Have to go out at 10 and hoping it’s not too icy to walk.

    1. You can clearly see where it snowed and where it didnt on that image. And can see the wedge of colder air that held tight in the CT River valley down to Hartford. I mentioned last night that it is pretty rare to have accumulating snow and ice in Downtown Hartford and then head 15 miles east to my house in Coventry at 750′ elevation and have all rain.

  14. Thanks TK. Yesterday morning the BZ radio anchor said a slight shift in the polar vortex was allowing for rain in Boston…..

  15. Thank you TK!

    Wordle: 4 – I am gladly joining Vicki in the lounge car. I hope we can drink hot chocolate and watch Hallmark Christmas movies.

  16. Thanks, TK.

    Happy to see some nice snow totals in places that have seen healthy snow amounts over the past few years, such as parts of Northern Massachusetts and New Hampshire.

    Never got to 32F here overnight and it is definitely not cold outside today, not by December standards. Looking ahead, I don’t see much real cold (again, by December standards; don’t compare it to other non-winter months).

    Looking back in history, we’ve had a lot of Decembers that featured cold periods. One of the more memorable ones was December 1980. After a mild start and one or two very brief mild spurts, it produced some very cold weather in Boston; sustained, too, despite some of the usual volatility.

    Were people talking about SSWs and polar vortices? Or “Decembers to Remember?” I doubt it, though perhaps they were. I know my father and mother remembered. They both talked a lot about the frozen and burst pipes that month.

    In any case, if I read about a “Polar Vortex” again or an SSW, I think I’ll vomit.

    1. Joshua – this ain’t Nuuk 🙂 Normal high for Boston yesterday was 46 and low 33.

      The projected NWS low for Boston is 10F tomorrow night and high Friday is 26F. Over the weekend, highs both days in the mid 30’s and lows in the 20’s. The stretch ahead is definitely below normal for this time of year. And that looks to continue next week as well.

    1. These things are NEVER modeled very well. At any location they will see a snow shower/squall or they won’t simple as that.
      I think we’ll now more tomorrow AM.

  18. Southern stream system WAY to the south next Monday. Its precip shield simulated to be hundreds of miles away.

    Polar/arctic airmass pouring into New England.

    High approaching from the west. Wouldn’t think to expect that scenario to produce ocean effect, yet here’s the 850 mb map.

    Wind from the NNE in eastern most and southeastern most Mass. Maybe too dry in the boundary layer ?? I may follow this.

    Reply

      2. 850 mb winds NNE, which is a great wind for Boston, however, surface winds are N to NNW. If surface winds were NNE
        as well, we might be in business. Still, something to watch.

        thank you for pointing it out.

        oh and yes, temperature differential between 850MB and surface and most especially the ocean temperature is plenty good enough.

  23. Yesterday’s storm in SNE on paper worked out well, but sometime the forecast can be right for the wrong reasons. I did not see the lack of gradient that held the cold air in the valleys. Particularly near me. (Snow was actually relatively fluffy until the freezing rain and rain came in about 3:30pm) Some of the least favorable snow accumulation areas in SNE (except the immediate coast) did comparatively well. There was a strip in southern Hampden county that was 3-6″ and I would have thought it they would all be 3″ max, if not less. Overall, the 0-1, 1-3, 3-6 (with spot higher amounts worked fine, but man, I did not see that cold air hangin’ tough on the block…

    Also, hello from London, where it was sunny and 50 today.

  24. Always interesting to read about those shoveling the snow and walking carefully on ice while I pour out the 1.2 inches of water out of my rain gauge this morning with bright green grass here along Buzzards Bay. I may need to even mow my backyard again Friday!

      1. Agreed. I am making a dedicated point to enjoy this holiday season more than in recent years and this pattern will help set the mood.

        The snowfall won’t amount to the total on rhe 10:1 ECMWF output, but it will be nice to have some cold dry air and some occasional light snowfall.

        On a separate note, I believe the online propagation of the 10:1 snow maps (particularly the ECMWF) and young mets, broadcast and otherwise,!over reliance on that model contributed to the hype and disappointment for some regarding the 12/2 event. Remember as a late as 00z 11/30 the ECMWF was depicting a 6-10″ snowfall Providence to Boston.

        1. This is our first holiday season without mom, so there will be a difficult aspect, but we are leaning into the celebrating of mom’s life and carrying on all the great holiday feelings that she (and my dad) established in the time they were with us. My son and I are doing all the usual things and mom’s place is decorated happy and bright as ever. We’ll be spending time there listening to music and playing games and all of that. We’ll have a Christmas Eve dinner and Christmas Day late lunch in her memory.

          Also, my son has declared 2027 (2 years from now) “The Year of Christmas” so we have time to make the ultimate playlists, movie & special line-up that will be spread across the year, and refine the decorating process for the season itself. It has to do with an album he’s releasing that year. 🙂

          1. Lost my dad at 58, 33 years ago. My mom somehow keeps living, but sadly this is the first year she will 100% not know it is Christmas. I have decided no matter what end of the spectrum I am on, I will no longer take Thanksgiving through New Years for granted.

            I think 2027 is an excellent year! Spare nothing for it.

            Reply

          2. Yeah, my mom’s been gone 14 years now. It’s always there, but no doubt that first year is an extra something to cope with.

            Good luck to your son with his album release down the road.

            And your right, JMA, it’s taken me longer than it should have, to really appreciate what you have in the moment.

    1. Hi. I apologize if I’m mistaken ….my memory is old…..but I don’t recognize your name. Wishing you a warm Welcome.

      1. We most certainly can since in much of SNE it happens less than 50% of the time. 😉

        I have never cared what the weather was, whether we had snow on the ground or not, etc. Christmas has ALWAYS been Christmas to me. It’s so much more than the weather. 🙂

      2. I can have Christmas every day of the year. Although it wouldn’t be special then, it sure would help this world

  32. Does anyone know what the WINDEX is for tomorrow?
    Curious because so far, not impressed with the Hi-Res models regarding possible snow squalls for tomorrow.

    Windex for snow squalls refers to “WINDEX,”
    a meteorological forecasting tool, not the cleaning product. WINDEX stands for the Wintertime Instability Index and is used by forecasters to assess the potential for snow squalls along cold fronts by analyzing atmospheric conditions like relative humidity, instability, and lift.
    What WINDEX is

    A forecasting method: WINDEX is a specific technique used to forecast the possibility of snow squalls, which are sudden, intense bursts of snow with high winds.
    Based on atmospheric data: It uses data from weather models to examine several key factors:
    Moisture: The amount of moisture in the lower atmosphere (boundary layer relative humidity, or R1).
    Instability: The difference in temperature between layers of the atmosphere, which indicates how much potential for rising air exists.
    Lift: The change in the “lifted index” over a 12-hour period, which indicates the potential for upward motion in the atmosphere.

    How it works

    Forecasters input these variables into a system, and if they meet certain criteria, the index indicates a higher probability of snow squalls forming.
    This helps differentiate between a forecast of scattered flurries and a more significant event with the potential for dangerous, whiteout conditions.

    Why it’s important

    Improves safety: WINDEX helps forecasters provide better warnings for hazardous conditions like whiteouts and icy roads, which can lead to accidents.
    Addresses limitations: Snow squalls can be small and difficult to forecast, so tools like WINDEX are crucial for providing the most accurate information possible.

    1. From the latest NWS discussion, no WINDEX Value, but they do discuss some of the necessary parameters.

      An arctic cold front will be crossing the region Thursday afternoon.
      A mixture of clouds and sunshine ahead of this front should result
      in highs mainly between 35 and 40…which is still below normal for
      this time of year. As the front crosses the region…shortwave
      energy coupled with 0-2 KM ThetaE lapse dropping below zero along
      with a touch of MUCape are favorable for a few brief snow showers
      and perhaps a localized snow squall or two. The one thing we are
      lacking is low level moisture…so this may keep the snow squall
      threat rather localized but something we still need to watch.

      Looks like the lack of low level moisture could be a major limiting factor.

      1. Not to mention that the Berkshires suck up much of any available moisture. Leaves us in central and eastern sections with a lousy flurry at best.

        Reply

        1. This isn’t a Lake Effect event. It’s an arctic front. Big difference. We cannot just assume the mountains will prevent snow squalls in eastern areas. Today’s front (and Sunday’s front) are both quite capable of producing them.

  34. The full moon is straight up so I don’t get to see it from my chair. But it’s pretty with the clouds. I can’t see rhe seven sisters tho although understand only six may be visible with the naked eye
