DAYS 1-5 (MAY 8-12)

The easternmost upper low of an omega block still controls our weather, but this pattern will be gradually breaking down and shifting during the coming several days. Initially, we have a surface low to our east today and we’ll be in a light north to northwest air flow with somewhat drier air for several hours. As the day goes on and we approach evening, we’ll start to see the air flow shift to easterly as a boundary settles just to our south and we begin to feel the effect of developing low pressure to our southwest. Rain chances go up as we reach evening but first in the form of isolated to scattered showers. As we move through the nighttime hours and into Friday, a steadier rainfall is likely. The movement of the new low pressure area will determine how quickly we break out of the steadier rain and see improvement. Right now, I lean toward a slightly quicker scenario in which the steadiest rain exits the region around or prior to dawn on Saturday, with the daytime hours just having the chance of additional passing showers as the low pulls away via the Gulf of Maine. High pressure then builds in with a stretch of fair weather for Sunday (Mother’s Day) and Monday, including a warming trend.

TODAY: Sun/cloud mix, then clouds overtaking the sky toward evening. Isolated to scattered showers by evening. Highs 65-72. Wind NW up to 10 MPH shifting to NE late-day.

TONIGHT: Cloudy. An episode of more numerous showers in the evening including some thunderstorms, especially in central MA. Patchy drizzle and scattered showers overnight including areas of fog. Lows 50-57. Wind NE 5-15 MPH.

FRIDAY: Cloudy. Periodic rain. Areas of fog and drizzle. Temperatures steady 51-58. Wind NE to E 5-15 MPH.

FRIDAY NIGHT: Cloudy. Chance of rain. Lows 45-52. Wind NE 5-15 MPH.

SATURDAY: Mostly cloudy to partly sunny. Chance of showers. Highs 57-64. Wind NE to NW 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 48-55. Wind NW up to 10 MPH.

SUNDAY: Partly sunny. Highs 65-72. Wind NW up to 10 MPH.

SUNDAY NIGHT: Clearing. Lows 46-53. Wind NW 5-15 MPH.

MONDAY: Mostly sunny. Highs 68-75. Wind W 5-15 MPH.

DAYS 6-10 (MAY 13-17)

A gradual shift in the wind flow from westerly to southerly early to mid period with fair weather to start then a chance of showers as moisture increases. The unsettled weather may continue into late period as some additional blocking is indicated with low pressure nearby.

DAYS 11-15 (MAY 18-22)

A hybrid pattern – partially blocking / partially progressive. Hard to pick up dominant weather systems but the overall trend is for less rain and near to slightly above normal temperatures.

  2. Philip, I believe you have a Dr appointment for your knee. I’m hoping it goes very well and that you are having less pain.

  9. There is a lot of variation in TV met forecasts for the arrival and departure of rain. I saw one where the forecast is for the rain to stick around til early evening Saturday.

    1. Last week was a little better than the week before. This week as you said shows improvement and next week should be a just little better. There is a real lag effect between rainy periods and drought relief.

  13. White smoke from the Vatican.
    I guess we’ll know really soon.
    I have my suspicions……

  14. I have a golf game at 3 in Natick. Do you think rain or t storms will throw us a curve?

    1. just mt 2 cents “possibly”
      watch the skies.

      btw where is there a golf course in Natick. I used to play a 9 hole course where currenty sits some sort of range/learning center

  15. Over under tomorrow into Saturday AM 1.4 inches here in JP? Should help or with drought for sure. Plenty of rain this spring.

    1. Thanks! Yeah I was feeling more optimistic, which is probably not the best route to take in spring in New England. 😉

  17. The cooling that started last year in the southern part of the North Atlantic Ocean has expanded and the Atlantic is now the coolest it’s been this century so far. This will likely have a notable impact on the upcoming hurricane season.

    1. And yet, April 2025 was the warmest April since 2024. Our planet is still warming overall, no matter what the oceans do.

      1. I was actually just talking about the Atlantic ocean temps and their probable impact on the tropical season.

        And there is a relationship between what the oceans do and the long term climate, and vice-versa. That would be like dismissing the impact of a large volcanic eruption. Can’t do it. Science is inclusive. 🙂

        Also, April 2024 vs. April 2025 is a very small sample in itself, and not really one to use when assessing the potential impact of SST’s on the tropical season. There’s also a fairly plausible theory out there that a warmer planet will not necessarily yield more tropical cyclone activity, but somewhat less. I’ll get into this soon with some info from legit sources. A colleague of mine is working on that. Additionally, there’s some new info coming out about the impact of Hunga Tonga, initially dismissed by many scientists as not a big deal. It was a bigger deal than they thought. Look for posts on that not long from now.

        When the AMO went positive it took a long time to start seeing the impacts of it. It’s now getting ready to head toward its negative phase (longer term, not just this short-term downward spike). The same will also be true there.

        Weather / Climate has so many things to consider. The relationship between the two is so complex.

  18. New Pope Leo XIV…an American!

    I am not Catholic so I have no opinion one way or the other.

    69 years old.

    1. I’m reading pope Francis had hoped for him to be chosen. He spoke out against Trump and Vance a week ish ago. Makes him very ok in my book.

  19. The South Coast sea breeze looks awesome on the visible satellite loop. 🙂

  20. RRFS, HRRR, and NAM leave me with some continued optimism for Saturday.

    1. Doesn’t make it all the way east and offshore. It gets into the area, stops, then moves more north with time, eventually even north northwest later tonight.

  22. Am I seeing some lightning down your way JimmyJames? Or maybe it’s north of you. ?

    1. There was a couple flashes of lightning and rumbles of thunder just before six this evening

  24. That should be it for the severe warnings, but now there’s a flash flood issue in that area due to the quasi-stationary batch of heavy rain.

    Eventually, as noted earlier, this will mush out into a general rain area and lessen in intensity before lifting to the north northwest out of the area later tonight.

  25. On and off heavy rain for over an hour now in Pepperell. Hope someone records a measure of it.

  26. Thanks, TK!

    Flash Flood Warning for…
    Central Worcester County in central Massachusetts…
    Eastern Hampshire County in western Massachusetts…

  27. We just drove home from Devens to Lunenburg. There was heavy rain and lots of lightning the whole way, and it’s continuing now.

  28. I almost chased to central MA, but I didn’t. Should have though…

    1. I thought you’d said north of 90 but then I read two hours before I was supposed to be awake

  29. On the eastern lobe, a cluster of CG’s off the North Shore (east of Lynn & Salem).

  30. Somehow just missed the bulk of that big slug of rain and thunderstorms that passed through central CT into east/central MA. On the fringe with only 0.07” here while BDL has reported 0.7” so far. Looks like some big totals will be coming out of Worcester County and the main event isn’t till tomorrow!

    1. 3.37” here since May 1/last Thursday now by the way. Likely will be up over 5” by Saturday.

  32. Killington calling it quits after Saturday. Lost a lot of snow this week with all the rain and high dew points. Jay Peak planning on going to Sunday.

      1. This will be the earliest they closed in years but not really a good comparison since they aren’t doing spring skiing on the Superstar trail this year. Normally they load Superstar up with 30 feet of snow but this year they are replacing the superstar quad lift with a six person lift so had to divert their late season skiing to the Canyon area so they could start construction early. It’s higher elevation in the Canyon but requires a long connection from the top of the gondola to access and then a long runout at the bottom to the base. Too long of a distance to maintain that deep of a snowpack in a warm rainy spring like this.
