DAYS 1-5 (DECEMBER 10-14)

Today is our “in-between” day after last night’s slug of rain (and some snow well to the northwest) and the upcoming wind and rain event for tomorrow. Weak low pressure just to the east slowly drifts away but low level moisture will remain trapped over the region today so we’ll be under an overcast and there can be periods of drizzle. Low level cold air dominates, and the air temps are near to just below freezing early this morning from the immediate north and northwest suburbs of Boston northward into southern NH and northwestern into north central MA. Watch for black ice in these locations, and any drizzle that falls can also freeze on surfaces until the temperature goes above freezing. There will be only a very modest temperature rise during the day today as the cold air remains trapped near the surface. Warmer air will finally invade the region from south to north tonight in response to a stronger southerly air flow ahead of an approaching front, driven by a low pressure trough moving in from the west. Low pressure waves ride up this front and we get waves of numerous to widespread rain showers and potential embedded thunderstorms Wednesday. Heavy rain can cause some ponding and road flooding, and watch for some strong wind gusts that can result in tree damage and some resultant power outages. If you have any holiday decorations vulnerable to wind, take steps to secure (or temporarily remove) them if possible. Out goes the rain, and in comes the dry and cold weather for late this week, accompanied by plenty of wind Thursday into Friday, which settles down by Saturday as high pressure builds in. The door is open for a few stray snow showers in our area Thursday and/or Friday, but these are not expected to be heavy enough to cause any travel issues.

TODAY: Overcast. Areas of fog / drizzle. Watch for black ice north and west of Boston along with some freezing drizzle. Highs 33-40 north and west of Boston, coldest southwestern NH and north central MA, 41-48 elsewhere, mildest South Coast. Wind N under 10 MPH north and west of Boston, E up to 10 MPH elsewhere.

TONIGHT: Overcast. Areas of fog / drizzle. Temperatures steady or slowly rising. Wind SE up to 10 MPH.

  3. Well, last year, we had December 19th cancelled as a school day because of down trees and a good part of Marshfield without power. I hope we don’t lose this Thursday to tree removal/power outage restoration.

      1. I remember that, Tom. We have conferences tomorrow night from 5:30-7:30. I will not risk my life for a handful of families!

    1. It’s ripping right above us, get it to mix down and it will be powerful. I am betting some 70-80 gusts will be present.

  9. Logan showing 0.41 inch for yesterday’s RAIN.

    Logan now showing 32. That may be a round, but still it is creepy low for the wet weather.

    1. Total for the event? I just changed batteries, recalibrated my ambient and it’s if great. Drained the solar panel energy etc. mine was for yesterday and overnight into today. Surprised it’s that much of a difference.

  17. Per the Mt Washington Auto Road webpage

    Its 24.3F at 1,600 ft (base)

    Its 37.6F at 4,000 ft

    and 30.5F at the summit

    1. 18Z HRRR forecast wind gusts in KNOTS for 7PM tomorrow

      https://ibb.co/NpL6gWR

      40 knots = 46.0312
      45 knots = 51.7851
      50 knots = 57.539
      55 knots = 63.2929
      60 knots = 69.0468
      65 knots = 74.8007
      70 knots = 80.5546

      So across the area we’re looking at basically 50-75 mph wind
      gusts. I excluded the lowest and highest.

      Interesting. Will it happen?

      1. I was living in Millis and it was a powder blizzard. nice drifts all over. and it was still snowing Monday AM and we had no school! yay!!!!

    2. I also remember also. I would have been 11 and remember making snow forts with my brother in the piles of snow at the end of our driveway.

  23. I don’t think we’re going to dislodge the low level cold west of I-95 until late morning tomorrow.

  24. Crossed the warm front this morning dropping my wife off at the airport.

    Left the airport, it was 39F, back to Marshfield, its 55F and all the windows fogged up.

    It feels nice and warm.
