DAYS 1-5 (NOVEMBER 28 – DECEMBER 2)

We’ll be impacted by a couple minor low pressure systems over this period, but no major storms will occur. Today, in moves the first, more quickly than originally anticipated, resulting in more clouds than I originally had forecast, but the daylight hours will be mainly dry until the very end of the day when spotty light snow (north and west) and rain (southeast) arrives. While a secondary low will develop south of New England tonight, exiting Monday via the Gulf of Maine on its way to southeastern Canada, we’re not looking at rapid intensification and any lingering rain/snow won’t be heavy. Any accumulation of snow will be minor and quite temporary. Behind this system will come a reinforcing shot of cold air for the remainder of Monday and into Tuesday. On Tuesday, a weakening clipper system will approach from the west but it looks as if this system will produce clouds for us, but no precipitation. As December arrives, we see fair and milder weather Wednesday as high pressure dominates, and the next low pressure area, rather small and fast-moving, will drag a warm front / cold front combo through the area with only some rain shower activity possible Thursday.

TODAY: Mostly cloudy. Spotty light snow central MA / northern RI / eastern CT and spotty light rain southeastern MA by late-day. Highs 37-44. Wind W to variable up to 10 MPH.

TONIGHT: Cloudy. Spotty light rain Cape Cod / South Coast, mix/snow elsewhere. Minor snowfall accumulation (coatings) possible. Lows 28-35. Wind variable to N up to 10 MPH.

MONDAY: Cloudy start with a chance of light mix/snow favoring southern and eastern areas, then partly sunny. Highs 38-45. Wind N to NW 5-15 MPH, higher gusts.

MONDAY NIGHT: Partly cloudy. Lows 18-25. Wind NW 5-15 MPH, higher gusts.

TUESDAY: Variably cloudy. Highs 37-44. Wind variable up to 10 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 23-30. Wind W up to 10 MPH.

WEDNESDAY: Partly cloudy. Highs 40-47. Wind variable up to 10 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Lows 30-37. Wind S up to 10 MPH.

THURSDAY: Variably cloudy. Chance of rain showers. Highs 46-53. Wind SW 10-20 MPH.

DAYS 6-10 (DECEMBER 3-7)

Fair, breezy, colder weather is back behind a departing cold front December 3. Fast-moving low pressure brings clouds and a precipitation chance (rain favored over snow) December 4, followed by a period of fair weather. Next low pressure system threatens with precipitation later in the period. This is the previously-mentioned active pattern but without big storms. Temperatures near to slightly below normal.

DAYS 11-15 (DECEMBER 8-12)

Active pattern expected with at least a couple low pressure systems to contend with. Temperatures variable but near normal overall. It’s too early to try to guess timing and precipitation types on disturbances.

  3. Thank you, TK.

    Sure is a snow sky. Youngest said it has a snow feel also

    We still have a light coating of snow on the deck from Friday night. I do love the smell of snow.

  17. Wishing all who celebrate a beautiful season of Hanukkah which begins in a matter of minutes.

    Enjoy a special First Night with family and friends!

  18. Way to go Pats!

    Nice to see some festive flakes for the game.

    18Z NAMS have BACKED off completely for snow tomorrow.

    There’s a big surprise.

    1. Thanks.

      I like it when Hanukkah is early. In my case, it means 8 days of lights (candles) from late November through early December. Then, around St. Nick’s birthday – December 6th – put up a Christmas tree with lights. Makes for a long festive season.

  20. Wow am I seeing a lot of disappointed people around social media tonight. Apparently they had been expecting a large snow event. This is what happens when people see one run of a poorly performing model and decide that because that’s the one that shows the most snow then that is what has to happen. Of course a lot of the weather weenie run Facebook pages had them believing it all along.

    They are not learning. Now I think I can just start laughing at them from here on… 😉

  22. Interesting temp contrast depicted on 00z GFS setting up over next week with chilly/cold southern Canada and mild Ohio valley and mid Atlantic.

    Little wave on around Dec 6th. Maybe high bridging to the north with warm advection precip nosing into New England ??

    Let’s see if this shows any consistency.

      1. I think there’s some hope for a setup like this.

        It’s northern stream dependent mostly, with the initial temp contrast set up by said jet stream and the wave is a weak southern impulse riding that temp contrast.

        Fits with La Niña.

  23. So now we know that the GFS cannot handle the current pattern. The inconsistency and ridiculousness showing up between operational runs is laughable. I’d advise not paying any attention whatsoever to the 06z run, which is SO FAR OFF its previous ideas I thought they uploaded the wrong model run at first…

    2. 0Z CMC and 0Z Euro have this feature, albeit not the same and much more rain and mix instead of all snow. But the feature is there. So there must be a possibility of at least something
      in that time frame. Not saying it will be a block buster
      snow storm, just something to watch. 🙂
