DAYS 1-5 (DECEMBER 25-29)
A cold front passes through today and brings the chance of a few snow showers (rain or snow showers south of Boston where temperatures are more marginal). A colder air mass arrives behind this for Friday and Saturday. A clipper low will come along and deliver a minor snow event late Friday to midday Saturday, with the best chance of accumulation snow to the southwest of Boston. This will be followed by a break, before the next low pressure area tracks north of our area and brings a mix to rain event Sunday night into Monday. There may be some icing involved in that system but details need to be worked out.
TODAY (CHRISTMAS DAY): Variably cloudy. Chance of a passing snow shower in the morning except mix/rain shower Cape Cod midday. An additional passing snow flurry is possible in the afternoon mainly north of I-90. Highs 35-42. W to NW 10-20 MPH.
TONIGHT: Clouds decrease. Lows 12-19. Wind NW 5-15 MPH.
FRIDAY: Clouds increase. Highs 22-29. Wind N 5-15 MPH.
FRIDAY NIGHT: Cloudy. Light snow develops. Lows 15-22 evening, rising slowly overnight. Wind variable to NE under 10 MPH.
SATURDAY: Cloudy with some light snow in the morning, favoring Boston south and west. Partial clearing afternoon. Highs 24-31. Wind NE up to 10 MPH.
SATURDAY NIGHT: Clearing. Lows 16-23. Wind variable up to 10 MPH.
SUNDAY: Increasing clouds. Highs 32-39. Wind variable up to 10 MPH.
SUNDAY NIGHT: Cloudy. Snow/mix/rain potential. Lows 30-37 then a slow temperature rise. Wind SE 5-15 MPH.
MONDAY: Cloudy with a chance of rain in the morning. Breaking clouds in the afternoon. Highs 38-45. Wind variable to SW 5-15 MPH becoming W 10-20 MPH with higher gusts in the afternoon.
DAYS 6-10 (DECEMBER 30 โ JANUARY 3)
A snow shower threat December 31. A light snow or mix threat January 1 or 2. Otherwise, a mainly dry and cold pattern to end 2025 and start 2026.
DAYS 11-15 (JANUARY 4-8)
Variable but overall near normal temperatures with a couple disturbances to bring some unsettled weather, but no indication of major storms at this time.

Thanks, TK.
TK and to everyone else, Merry Christmas!
So yes, contrary to what was mentioned on the previous post comments section…
Saturday is not a miss. It’s not a major snow event. It was never expected to be. There will be areas that see very little snowfall from it. This is the nature of a system in a dry environment that has a low center passing to the south. There is NO REASON WHATSOEVER that it’s a “miss, because it would have been snow”. That is just simply NOT the case. I have said this now so many times…
The idea of snow missing and rain hitting on a routine basis is a false notion.
Thanks TK !

Hopefully the trends hold for my area of CT for a nice solid 4-8 inch snowfall.

I was hopelessly lost on this one. Lucky to get it on 5.
Hopefully you get into more of the action.
For laughs 12z NAM. This has the narrow heavy band north of NYC. 12z HRRR had that coming into NYC

Snow amounts for Saturday:
BOS = C-1โ ๐
NYC = 6-10โ
The NYC amount I saw on GMA (ABC)
This is the gloomiest Christmas Day I can remember. After I returned from breakfast I decided to turn my indoor candles back on.
If only we had a nice snow cover to take the edge off. ๐
It is very dark here as well!
Anyone seeing any flakes? Radar says it’s snowing , but NOTHING is reaching the ground, not here anyway.
If itโs not snowing up there in JP itโs certainly not snowing down here in Quincy.
Not even close to gloomy here. We had a nice period of mood snow, now a sun/cloud mix.
I think many cloudy, wet ones we had when I was a child were far more “gloomy” than today. Today is beautiful.

Very light snow falling in Reading MA.
I’ll be back in Woburn at noon.
we have HEAVY NOTHING falling here. ๐ ๐ ๐
Another issue with me is when I see C-1โ I used to think on the positive side that maybe close to 0.5โ or at least .25โ. ๐
It seems nowadays Boston canโt even get the coating! Like yesterday it never sticks. ๐
It does snow in Boston and it does stick there. Don’t use recent history as “always”. It’s not even close to correct.
Interesting observation.
Where I live in JP the altitude is about 71 feet. I went to Brookline to pick up Chinese Food last night. There was nothing but spotty coatings left here and there down here. The path to Brookline took my by Larz Andersen Hill, altitude 290 feet.
So the road I was on was perhaps 150 feet altitude and maybe 1/2 mile from my house. There was a SOLID coating covering all non-paved surfaces. It was pretty amazing to see that difference over a very short distance and a little more than double the altitude. Pretty cool.
Hope yours was better , my food was horrible last night , North End Italian food here in my home today .
Oh, it was AWESOME!!!!

Thanks TK and Merry Christmas all!
Thanks TK! I had a wonderful Christmas morning sunrise run along Buzzards Bay. I have four young adults – including 23 year old triplets – and they are all out of town this Christmas. So it is much more quiet than 15 years ago. This morningโs peace felt like
A gift
Sun is out now. Yay! ๐
Up to 37 here.
First Winter Storm Warning of the season for my area!
Good for you Jimmy. Enjoy your Saturday snow! ๐ โ๏ธ
I donโt believe Boston has even been in a Winter Storm Watch or Advisory so far.

Going into December, the trend was “cold & dry”.
So far this month in Boston: cold & dry.
I do think Boston has a shot to reach about half the month’s long term average for snowfall depending on how things play out the next several days.
Made it to 40F a while ago.
Winds picking up. I could see a 20 pt drop in temps by midnight.
Made 39 here, now 38

Winds blowing hard. Temp down 6 degrees from todayโs high.
Down 8 degrees to 32F.
Today’s 18z 12km NAM is a good case for what that model should have been retired months ago.
