DAYS 1-5 (DECEMBER 25-29)

A Christmas Day travel hazard due to freezing rain (except the South Shore of MA and South Coast region where the temperature is already and will remain above freezing. As the rain moves in early this morning from the west, it will freeze on untreated surfaces where temperatures are at or below 32F. We won’t see enough icing for tree damage and power outages, but we will see enough for hazardous driving and walking on untreated surfaces until such a time that the temperature rises sufficiently to stop the process and melt the ice on these surfaces. This may take much of the day to happen especially over interior areas to the west and north of Boston. With low pressure pulling away and intensifying through Sunday, other than the possibility of a few snow flurries from an upper level disturbance, we will be dry and not too cold, so most icy spots will melt away / dry up and walking conditions will improve. High pressure brings fair weather Monday into Tuesday. The next low pressure area is due Wednesday with another round of unsettled weather, early leaning toward rain over snow.

TODAY (CHRISTMAS DAY): Cloudy. Rain arriving from west to east early. Icing conditions away from the coast, gradually diminishing from southeast to northwest later in the day. Highs 33-40. Wind E to N up to 10 MPH.

TONIGHT: Mostly cloudy. Chance of mix/snow showers. Lows 26-33. Wind N 5-15 MPH.

SUNDAY: Variably cloudy. Chance of snow showers. Highs 35-42. Wind N-NW 10-20 MPH and gusty.

SUNDAY NIGHT: Clearing. Lows 17-24. Wind NW 10-20 MPH, diminishing.

MONDAY: Sunny to partly cloudy. Highs 33-40. Wind W 5-15 MPH.

MONDAY NIGHT: Variably cloudy. Lows 23-30. Wind variable up to 10 MPH.

TUESDAY: Variably cloudy. Highs 35-42. Wind variable up to 10 MPH.

TUESDAY NIGHT: Mostly cloudy. Lows 28-35. Wind SE under 10 MPH.

WEDNESDAY: Cloudy. Mix/rain likely. Highs 38-45. Wind SE 5-15 MPH.

DAYS 6-10 (DECEMBER 30 – JANUARY 3)

Two disturbance may bring episodes of precipitation during this period. Neither look like major events. Temperatures near to slightly below normal.

DAYS 11-15 (JANUARY 4-8)

Variable temperatures, averaging close to normal. One or two disturbances bring precipitation threats. Timing / details not possible this far in advance.

  1. Thank you, TK.

    Good morning and a very Merry Christmas to everyone in the WHW family …..both those who post and those who read!

    1. 30 here and still drizzle. I think the roads are ok as they have been treating, but My son in law in Uxbridge will pick me up since I no longer drive in iffy weather.

  18. Busiest Christmas I’ve worked in a while. Models really underestimated the amount of precip, which is what is causing all sorts of problems. Had one DPW tell me that they’d been out treating all morning, but had to start putting sand down with the salt because the rain was just washing the salt away.

    Route 3 in Nashua was shut down at Exit 5 for nearly 3 hours this morning due to a 15-car accident. I-95 was closed between Seabrook and Portsmouth due to a 50-car accident.

    1. Well we know about the guidance…

      Either way the icing was known yet people continue to try to drive like it’s not icy.

  19. Happy Holidays All!

    “I’m dreaming of a cold rainy Christmas, just like the ones I used to know.”

    Icicles on my deck banister. A couple more hours of this I think.

    1. We’ve had more rainy Christmases in SNE than snowy ones. The notion of it always having snowed in the past is false and incorrect.

      Memory is interesting in that it will pick out a “favorite” or two and apply them to most. Cold hard statistics will show otherwise. That’s what we go by around here – stats. Real numbers don’t lie. 🙂

      I was thinking about Christmas 1978 where we had a quick inch of snow in the early morning followed by a soaking rain. Or Christmas 1982 where we had a pouring rain with temperatures in the 50s all through Christmas Eve into Christmas morning.

      Two of the coldest Christmas Days were in the early 80s (1980 & 1983), otherwise we had a lot of mild ones that decade.

      But this idea that Christmas was always white around here – nope.

      I’ve known this before I even had access to the stats – at least locally – from the stories my older brothers told me.

      You have to go a distance N & W of the Boston area before your chances of a white Christmas go up significantly.

      1. Agree. I do not remember all that many white Xmas days. I sort of look at the idea of a white Xmas as a Longshot.

        1. This is why the Boston (Logan) odds are around 15% and it climbs to only 25% on the western side of the city.

      2. 78 was when we had about a foot on December 9. Often it gone before Christmas arrives. It was last year also

  22. In reference to the links JPDave posted – not a lock, but watch for a couple inches of sneaky snow metro Boston and North Shore tonight… inverted trough setup, always tricky.

    1. I meant to mention that it looked like an inverted trough to me. We shall see.

      Of course what little snow that fell yesterday, all sublimated during the day yesterday and overnight.

  23. Thanks TK and Merry Christmas everyone! It was officially a white one here after the 2”+ of snow yesterday and while the rain has cut that down a bit, still 100 percent snow cover at this hour. Kids had shoveled the driveway yesterday so it was pretty much a skating rink this morning when we got up. Things improved by late am and we are sitting at 33 degrees now.

    1. Indeed.

      Nice to see that the Mountains of Utah, Colorado, New Mexica and Arizona share in the mother load!!!

    2. Mother nature sending them all the snow that they have been lacking the last several years. Might help with the summer/fall fire season.
