DAYS 1-5 (AUGUST 9-13)

A frontal boundary and area of low pressure just to the south of New England will combine to make today fairly cloudy and on the cooler side of normal. Showers extending from parts of RI across parts of the MA South Coast including Martha’s Vineyard as of 7 a.m. will linger there and also expand eastward across much of Cape Cod including Nantucket before diminishing. A few more showers may pop up a little further north with the heating of the day, but these will be limited. The frontal boundary to the south will lift northeastward across the region as a warm front Tuesday with some cloudiness and perhaps an isolated shower, otherwise it will introduce warmer and more humid air again. Then the classic Bermuda High heat hump will set up shop from Wednesday through Friday with very warm to hot and humid weather. Each of those afternoons will carry the chance of isolated to scattered shower and thunderstorm activity, with a gradual increase in chances and coverage each afternoon as it looks now.

TODAY: Mostly cloudy. Showers likely from RI to far southeastern MA into mid morning then diminishing. Isolated showers anywhere this afternoon. Areas of fog early. Highs 75-82, coolest in coastal areas. Wind NE to E 5-15 MPH.

TONIGHT: Mostly cloudy. Patchy fog. Lows 62-69. Dew point lower to middle 60s. Wind SE under 10 MPH.

TUESDAY: Variably cloudy. A shower possible, mostly during the morning. Highs 77-84, coolest coast. Dew point middle to upper 60s. Wind SE up to 10 MPH shifting to S.

TUESDAY NIGHT: Partly cloudy. Patchy fog. Lows 66-73. Dew point middle to upper 60s. Wind SW up to 10 MPH.

WEDNESDAY: Partly cloudy. Isolated afternoon thunderstorms. Highs 86-93. Dew point upper 60s to lower 70s. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Patchy fog. Lows 67-74. Dew point upper 60s to lower 70s. Wind SW under 10 MPH.

THURSDAY: Partly cloudy. Isolated to scattered afternoon thunderstorms. Highs 87-94. Dew point lower 70s. Wind SW 5-15 MPH.

THURSDAY NIGHT: Partly cloudy. Patchy fog. Lows 68-75. Dew point upper 60s to lower 70s. Wind SW under 10 MPH.

FRIDAY: Partly sunny. Scattered afternoon thunderstorms. Highs 88-95. Dew point lower 70s. Wind SW 5-15 MPH.

DAYS 6-10 (AUGUST 14-18)

A cold front comes through the region most likely morning and midday Saturday (Aug 14) with a chance of showers/thunderstorm favoring eastern and southern areas before drier and slightly cooler air arrives. High pressure builds in with pleasantly dry weather Sunday (Aug 15). High pressure may sit over the region with continued fair weather and a gradual warming trend for the balance of the period. Possibility that some moisture approaches from the south by the end of the period.

DAYS 11-15 (AUGUST 19-23)

High pressure should sink to the south opening the door to more humidity and better chances for shower activity again during this period. Also need to keep an eye out for tropical activity to the south mid to late period, pending potential development in the Atlantic Basin.

  6. For those interested the IPCC report for group 1 has come out. I am going to be more interested in group 2 and 3 when their stuff comes out but this is just as important for people to see. Cool interactive maps go along with the report. https://www.ipcc.ch/report/ar6/wg1/#FullReport https://www.ipcc.ch/report/ar6/wg1/downloads/factsheets/IPCC_AR6_WGI_Regional_Fact_Sheet_North_and_Central_America.pdf
    Overall increasing moisture unfortunatly decreasing snowfall based on these models. Which is a change from early 2000s for our area. https://interactive-atlas.ipcc.ch/regional-information#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

    1. Excellent, Matt. I played with some. Will look more later today. I will share with a couple of friends if I may.

  8. Thanks, TK.

    Rain stopped. Sun is out (though rain is coming again) and it’s 20C (around 70F). Time for the beach.

  12. Rain’s back – pouring again. Temp dropped to 59F. The nice thing is, I’m enjoying sitting with my daughter in a cafe. W e have a window seat with lots of ventilation.

    1. That is so cool that you are able to spend time with your daughter. Wish the weather was a little nicer for you.

  13. Do you have any insights on Saturday? Thought the heat was going to break but notice a few stations now have high temp at 90. Trying to make some plans as we start our vacation. Thanks.

    3. It’s a cute 2016 photoshop, well known around the net, often believed as real, but very not. 😉

  15. Thanks, JPD. I really don’t mind the weather. I lived here and in Holland, so I’m accustomed to it. It’s kind of exciting, too. That rain shower – which was a downpour – has gone and the sun is trying to peek through again. Back up to 18C (~66F; I’m guessing). Computer says “rain is coming” though.

    Robert Frost should have lived here. He might have written some great poems about changeable weather.

    2. It’s no wonder the pilgrims set sail on the Mayflower, just for the climate alone. I had no idea their summers were so lousy. I may even consider scaling back my opinion on our late week temps and humidity levels. 😉

    2. With our luck this year, one of these systems will make it up the coast and nail us. If so, let us hope it is TS or no more than a minimal hurricane.

  18. Hi Vicki,

    Thanks for asking! Healing slowly but steadily which is good. Can’t get back to hiking for another 2-3 weeks at least.

  19. This NE breeze feels great down here today. We didn’t have much wind yesterday and it was quite uncomfortable.

  20. Longshot, glad to know you’re healing. Take care.

    So, in essence it rained all day today, as it has all 4 days of my trip. Yes, there were brief glimpses of sun today, almost as if to tease Londoners. The heavens really opened up this afternoon. Torrents of rain. I got completely soaked to the skin, after a lorry went through an enormous puddle at blazing speed and splashed me and my daughter. It was like a wave of water. Went into my face and all over me. I got the brunt of the tidal wave. My daughter just the edge, thankfully. The monsoon rain itself was unbelievable, especially during a 2 to 3 hour span. I’ve never seen so much rain, even in Boston last month when we had heavy rain. The rest of the day it was mostly light to moderate rain. Now it’s quieted down, but it says “rain coming” on my computer. Still 61F. Should warm up tomorrow and dry out, but we’ll see.

      1. It’s been 68-70 down here. The only day we noticed it was yesterday. Otherwise, the ocean breeze has masked the humidity pretty well.

        We can see the humidity though, literally on the canper’s screens. The side facing the wind has beads of small water droplets forming on it all over.

        Kinda glad we’ll be home for the Wednesday thru Friday stretch.

  23. This heat coming to me will be like what we had the first few days of June and last few days of June. Hopefully this will be the last of the big time and heat and humidity for summer 2021.

  25. Seems like a bit of an enigma for this Saturday. Eric has a high in the low 90s while Harvey is looking at 83 as tops.

  26. Seems like I could be seeing a tropical storm in my area tomorrow. Wasnt really thinking this thing was going to develop into a tropical storm but they are saying its a possibility.

      1. im more prone to Wind as I am about a thousand feet up on a rather steep slope. What ever they call for wind add about 10 to 20 mph to it and thats more likely what I will experience at my apartment. rain flows around the left side of the house towards the gut (temporary streams). My area is looking at 2 or 3 inches of rain. It will fill up the cistern 🙂
