Wednesday December 17 2025 Forecast (7:30AM)

DAYS 1-5 (DECEMBER 17-21)

High pressure sits to the south today with a low pressure trough approaching from the west. The moisture-starved trough will do nothing but help the breeze stay active and gusty today into tonight, and shift the wind a bit before the high pressure area noses in and diminishes the wind on Thursday, which will continue a trend to less chilly air. A stronger, larger low pressure area cutting through the Great Lakes Thursday night into Friday, then heading down the St. Lawrence Valley later Friday, will produce a stronger southerly wind, and with the help of a sharp cold front moving into the region, a solid band of rainfall, which will largely wipe out any snow and ice on the ground. As the front moves through, the rain shuts off, the wind shifts to west, and we see a return of dry, colder air Friday night through Saturday, though not as cold as the recent cold air mass we experienced. A weaker low will be passing north of our region on Sunday, and its warm front / cold front combo can produce brief precipitation around here, mainly northern areas, but this should be minor at best. Mainly noticed will be the mix of sun and clouds and breezy weather for Sunday. The winter solstice occurs on Sunday at 10:03 a.m. EST.

TODAY: Sunshine and high clouds. Highs 37-44. Wind SW 5-15 MPH with higher gusts.

TONIGHT: Partly cloudy. Lows 24-31. Wind SW 5-15 MPH shifting to NW with higher gusts.

FRIDAY: Overcast with widespread rain showers including the slight chance of thunder during the morning. Showers end west to east with a sun / cloud mix developing during the afternoon. Highs 55-62 in the morning, falling through the 50s into the 40s from west to east during the afternoon. Wind S 10-20 MPH except 20-30 MPH South Coast, gusts as high as 45-55 MPH, strongest coastal areas and higher elevations, shifting to W from west to east midday on.

    1. Yikes. 2 is superb. We don’t see a lot of 2s.

      I’m in the caboose with 5. 3 and 4 were words that fit but had wrong first letter.

      1. Thank you. You got it, so that is good.

        I tried a new starting word and picked up 1 letter in position and one letter out of position. So I started trying words in my head and was having trouble getting any to fit. Then it just came to me. Try this word and I figured perhaps I’d catch another letter or 2, BUT it WAS the WORD.

        I have played 178 games and only got it 2 guesses 4 times.

          1. Thank you. Crazy game.
            Sometimes we’re all over it and sometimes we are totally lost.

            There are many here that are totally on it more often than not.

  1. Thanks, TK!

    The Wayback Machine today stops at December 18, 2023, two years ago tomorrow, when a period of strong winds (60+ mph) and heavy rain blew through the area.

    Much of Middleborough lost power that morning. We had an unexpected dismissal during lunch period.

    Vicki posted this radar image on 12-18-23 around noon as the most intense weather crossed the region:

    I wonder if we will have a similar set-up this Thursday night and Friday. A High Wind Watch has already been hoisted for the Cape and the Islands.

  2. Yesterday felt MUCH warmer during my run than today. Despite the colder temperature, sun yesterday felt warm, frankly. Today’s lack of sun makes a big difference.

    I don’t know the physics of it or biology, but I do believe that for long distance running the sun may be more of a determinant of body adjustment than the outside temperature: In both good ways and bad. In summer, the sun is my enemy on a long run. I hate it. In winter, on the other hand, the sun is my friend. I like it.

    1. I coached track and cross country. Long-distance runners are the most dedicated athletes to their sport. No matter the weather, they put in the roadwork.
