DAYS 1-5 (AUGUST 7-11)

A small area of high pressure keeps the region mainly dry today, but a weak trough approaching from the north may be enough to trigger a few isolated shower or thunderstorms in southern NH and maybe north central MA by late afternoon into evening before they fade away with the setting sun, which will otherwise be filtered today by a combination of high clouds and some high altitude smoke that we’ve seen several times so far this summer. As we get to tonight and Sunday, we’ll be in between an approaching front from the north and a weak area of low pressure to the south of New England. The front will help trigger a few isolated to scattered showers and thunderstorms during the day Sunday, especially in southern NH and northern MA, while the low to the south may send a few showers into the South Coast region a few times during Sunday. This system will still be sitting there but drifting slowly northeastward during Monday while the front will have pushed southward across the region and high pressure builds over eastern Canada. This combination may result in a few lingering showers into early Monday mainly over RI and eastern MA, otherwise a cooler maritime air flow will dominate the region during Monday. This gradually shifts to a more southeast to southerly air flow during Tuesday as the front that had gone by from the north later Sunday will be coming back northeastward as a warm front, and this will bring some clouds and possibly a shower to a few areas Tuesday but otherwise expect dry weather. The feel of summer is back for Wednesday with high pressure building off the US East Coast and increasing heat and humidity in our region as a result.

TODAY: Filtered sunshine. A pop up shower or thunderstorm possible southern NH late-day. Highs 83-90, cooler South Coast. Dew point 60s. Wind SW 5-15 MPH.

TONIGHT: Mostly cloudy. Patchy fog. Lows 63-70. Dew point 60s. Wind SW up to 10 MPH.

SUNDAY: Variably cloudy. Isolated to scattered mainly afternoon showers and thunderstorms favoring southern NH and northern MA. A few showers possible near the RI and MA South Coast. Highs 82-89, cooler South Coast. Dew point 60s. Wind variable up to 10 MPH.

SUNDAY NIGHT: Variably cloudy. Chance of showers mainly RI and southeastern MA. Patchy fog. Lows 58-65. Dew point near 60. Wind variable up to 10 MPH shifting to NE.

MONDAY: Variably cloudy morning with a chance of showers RI and eastern MA. Mostly sunny afternoon. Highs 76-83, coolest coast. Dew point near 60. Wind E 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Patchy fog. Lows 59-64. Dew point upper 50s to lower 60s. Wind E under 10 MPH.

TUESDAY: Variably cloudy. A shower possible. Highs 77-84, coolest coast. Dew point lower 60s. Wind SE up to 10 MPH.

TUESDAY NIGHT: Variably cloudy. A shower possible early. Lows 65-72. Dew point lower to middle 60s. Wind S up to 10 MPH.

WEDNESDAY: Partly cloudy. Highs 85-92. Dew point middle to upper 60s. Wind SW 5-15 MPH.

DAYS 6-10 (AUGUST 12-16)

High pressure remains off the East Coast while a frontal boundary slowly approaches from the northwest increasing the chance of showers and thunderstorms during August 12-13. Drier air should arrive with Canadian high pressure moving in during the August 14-15 weekend continuing through the end of the period.

DAYS 11-15 (AUGUST 17-21)

Overall pattern looks dry with high pressure in control, but high pressure should sink to the south with time allowing it to become more humid again with an eventual increase in the shower and thunderstorm chance. We may also need to keep an eye on potential tropical activity in the Atlantic off the US East Coast by this time, at least by later in the period.

  2. Thank you, TK. Lovely weekend we are having. Birthday daughter and family were in Humarock yesterday. Should I know what is causing the larger waves?

      1. 🙂 🙂 🙂

        We saw huge swells Thurs and yesterday down here. I think they were generated by that system that gave all the rain to SE Mass. They have definitely dropped off as of this morning.

        1. Thank you. Kids said they’d carved a ledge in the ocean. Also an area toward 4th cliff is all sand.

          1. They were powerful swells. There’s a sandy beach here with a rocky climb off the beach. The big swells Thursday and last night at high tide reached half way up the rocks and pulled some of them down, so now, the sandy beach starts a little further out. The rocks are the size of a hand or a little bigger.

            Hopefully, they had a great day, it was a super beach day !!

  7. It’s beautiful down here at the western edge to the entrance to Buzzards Bay.

    On our 4th or 5th day now, I’ve lost track …….. within a couple miles of the water, they are so susceptible to a southerly storm surge. At high tide, I’m not sure a large area is more than 2-3 vertical feet above that water line.

    We did see a house raised about as high as I’ve seen a house raised before, I’m guessing 10 ft or more. I keep thinking that home owner lived the surge of Hurricane Bob. We saw other houses raised, but not quite as much as this particular one.

    1. Lots of farm land just away from the ocean and ton of farm stands, selling everything. We had delicious corn the other night, off the grill. We’ve been driving around the area of little Compton, RI to Dartmouth, MA

    2. If I had a house on the south shore…sighhhhhh….id sure get it as high as safe.

      A house next to the one we rented on hum for years is for sale. It is raised only a minimal amount. It won’t be there long. The house on the other side was purchased a few years ago for an obscene amount, another obscene amount was added for gutting and remodeling but it wasn’t raised. The house we stay in is a whole lot larger now than it was when it washed into the river during the no name storm. Oddly, though I don’t think the oldest house in the peninsula is raised.

  10. Heavy rain a few times today in London, albeit brief spells, some off and on light rain showers, too, clouds of all kinds in the sky with small patches of blue, and several cameo appearances of the sun, with temps mostly in the upper 50s until they `spiked’ this evening to 64F. A repeat looks to be in store tomorrow and Monday.

  11. Hello, everyone, been a while since I posted. So many distasters going on. Talk about extreme weather made worst by anthropogenic climate change. Our planet is screaming at us yet many people in power are doing nothing about it in terms of actual action. climate crisis is here, its not in the future need to start acting like it is. ON a nicer note I am going to be heading back to Massachusetts for December/Early January. I looked at some of the climate models just for giggles, they look good for early winter 😛 Also I seriously hope the GFS weather models is wrong and the EURO is correct in the Caribbean. The models are not handling that monsoon trough and the spin that well.

      1. thats my hope so I can go skiing, last season I was only able to do 3 hours of skiing because of Covid19 and that I went back to the VI for an internship.

  12. Western Atlantic part of the basin will need to pay attention to things soon.

    Been pretty quiet in the Atlantic this season (actually the tropics in general have been fairly quiet in the N Hem). Atlantic wakes up a bit now.
