DAYS 1-5 (MAY 9-13)

Over the next few days we’ll see a break-down of the omega block pattern that’s been in control of the weather. But to get there, we have to go through another bout of wet weather. This started somewhat last evening especially north and west of Boston with a band of rain and thunderstorms, that later on lifted northward and away, but today, low pressure approaching from the southwest brings the rain back during the course of the day, especially midday and afternoon, into evening. Tonight it becomes more showery, lasting into early Saturday as the low pressure area cuts right across our region from southwest to northeast. Ahead of it blows a genearlly easterly wind, keeping us cool today. The wind goes variable as the low crosses the region. On the back-side of the low we get into a westerly flow Saturday, but wrap-around moisture can still cause scattered showers for a part of the day, and complete clearing won’t take place until Saturday night. This does set up a splendid Sunday (Mother’s Day) with sunshine and pleasant air as low pressure pulls away through eastern Canada and high pressure builds our way from the west. This high will sink to our south early next week with continued fair weather and a warm-up.

TODAY: Cloudy. Areas of fog and a few patches of drizzle during the morning. Rain arrives southwest to northeast midday on. Highs 50-57. Wind NE to E 5-15 mph.

TONIGHT: Cloudy. Rain evening. Numerous to scattered showers overnight. Areas of fog. Lows 46-53. Wind E to SE 5-15 MPH, becoming variable.

SATURDAY: Areas of fog until mid morning. Mostly cloudy to partly sunny. Scattered to isolated showers. Highs 57-64. Wind variable to W 5-15 MPH.

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

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

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

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

MONDAY NIGHT: Mostly clear. Lows 48-55. Wind WSW 5-15 MPH.

TUESDAY: Mostly sunny. Highs 70-77, cooler South Coast. Wind SW 5-15 MPH.

DAYS 6-10 (MAY 14-18)

A hybrid blocking / partially progressive pattern is expected at mid month. This period should see the return of some unsettled weather, but timing and details are TBD. Temperatures near to slightly above normal.

DAYS 11-15 (MAY 19-23)

Transition from the hybrid pattern mentioned above to a more progressive pattern with a drier trend – brief unsettled episodes – and variable temperatures but no extremes expected.

  5. Thanks TK

    I must have misunderstood as I thought the rain was coming early today and lasting all day.

    1. For the serious part of the rain, I’m figuring 1 PM start time today and an end time of 10 AM tomorrow.

  6. Thank you TK.

    Easterlies will in play for me so I am putting the over / under at 53F.

  7. Thank you TK.

    Easterlies will in play for me so I am putting the over / under at 52F.

  19. 51. And as I duck, I’ll add that I don’t mind this weather at all. There is a kind of comfort about bundling up a bit.

  20. NWS forecasts roughly an inch of rain (between a half inch and an inch and a half) outside of the high terrain spots. Also predicts that much of the rain will be offshore by midnight. Hopefully we can get some quality outside time tomorrow.

  23. We’re at 48 here. Still UGHHHHHHHHHHHHHHHH!()@#*!(@#*()!@*#()*!@()#*(!)@*#()!*@#)(*!@)(#*()!@*#()!@*#()

  25. No Pillip yet today. I hope his Dr appointment went well yesterday..or maybe it’s today which would explain the silence.

  27. Watch out next 3-5 or 6 hrs.

    2 areas of rain that look impressive.

    Potential for localized, quick impact street flooding.

  29. Thanks TK.

    49F and pouring here in Coventry CT. Approaching 0.75” so far this afternoon and 4.10” for the first 9 days of May.

      1. They probably should hoist a flood advisory which brief flash flooding from Worcester to Boston as that next blob looks headed there.

  32. I do wonder if we are at least “sort of” in a somewhat similar pattern like May 9, 1977?

    I would say if this were February or even early March, the radars would be a very nice shade of “blue” to say the least. Oh well. ❄️

    1. If this were mid winter, this would likely be a rain event for most areas east of Worcester, mixed for the hills, and snow for the mountains.

      This is not the same pattern that we had for the May 9-10 1977 event, although cold upper level low pressure was involved.

    1. Glad it worked out. Despite the damp start, I’m optimistic for most of tomorrow. Wet ground early. Can’t rule out a few lingering showers early and a few more passing ones in the afternoon. But I think down your way, the vast majority of the day is dry.

    1. I must say I was surprised to see only 0.36 in the bucket when I got home. The rain seemed heavier.

      1. Yup. What was once totally abstract, my retirement on June 20 is now very real to me. I uploaded my last progress report notes before I left school for the weekend. They posted for my position last week! That was very weird! 🙂

          1. You don’t know how much I am going to miss interacting with the kids.

        2. Oh my. I sincerely apologize. I somehow missed that you will be retiring. You, I absolutely know, will be very missed. I wish for you many happy years ahead full of one adventure after another .

          1. Thanks so much, Vicki. It’s been 42 years. I owe it to Mrs. Fantastic who is a retired Reading teacher. There are other adventures ahead for us.

  39. What a drenching in SE Mass ! Thick heavy rain in the last 4 hrs dropping 1-1.5 inches.

    Very much needed, but hopefully slow transition to better tomorrow and then a beautiful Sunday.

  41. Rain dying down now on north shore. Might try a walk along the shore, but it is chilly. 46F.

  42. Strengthening 500 mb low passing overhead this morning.

    North of it and it’s the conveyer belt right off the Atlantic.

    It will be interesting to see what pivots SE the next few hrs.

    1. Light rain now. Waiting for the wrap around! Might keep coming through the late morning to noon or so.

  44. Good morning!

    Just 50 here. 1.65″ rain for the event with more to come???

    My phone indicated that we had some lightning strikes to our northeast earlier this morning.

    1. A little bit left to go, but we’re heading down the homes stretch.

      There were thunderstorms offshore to the east earlier.
