Tuesday August 18 2026 Forecast (7:19AM)

DAYS 1-5 (AUGUST 18-22)

Low clouds and areas of fog are dominant as we start today with low level moisture trapped under an inversion in the lower atmosphere, and not enough wind to mix the air efficiently at first. This will change as weak low pressure to our east pulls away and the sun works on the atmosphere from above, eventually transforming our sky into a sun / cloud mix, although the colder air with upper low pressure just to our east can be enough to trigger a pop-up shower this afternoon, particularly from the I-95 belt eastward. Tranquil weather takes over tonight and Wednesday with plenty of sun and a warm-up during Wednesday as high pressure slides overhead then offshore. A southwesterly breeze will pick up later Wednesday as a cold front approaches our region from the northwest, but this front will not be in a grand rush to get by us, and will take most of the day Thursday to do so. This triggers a shower and thunderstorm chance that day, but I’m not expecting widespread coverage, nor am I expecting any severe weather. The front ambles offshore, barely, and slows to a crawl, or stalls completely, as we move through Friday into Saturday. Currently, I am still anticipating this front to be just far enough to the southeast so that high pressure can get close enough to give us fair weather those days. The forecast gets tricky here. We’ll also have to watch an initial low pressure wave moving along the front on Saturday that I do expect to stay offshore.

TODAY: Abundant low clouds and areas of fog give way to a mix of sun and clouds. A pop-up shower possible this afternoon, especially southeastern NH, eastern MA, and RI, but only isolated coverage. Highs 75-82. Dew point lowers to sub-60. Wind N to E up to 10 MPH.

TONIGHT: Partly cloudy. Patchy fog. Lows 58-65. Dew point upper 50s. Wind variable under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 80-87 except 73-80 Cape Cod. Dew point increases to lower 60s. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Patchy fog. Lows 62-69. Dew point 60+. Wind SW up to 10 MPH.

THURSDAY: Variably cloudy. Probable showers. Chance of thunderstorms. Highs 77-84. Dew point in 60s. Wind SW 5-15 MPH.

THURSDAY NIGHT: Partly cloudy. Lows 61-68. Dew point falls just under 60. Wind W up to 10 MPH.

FRIDAY: Partly sunny. Highs 75-82. Dew point sub-60. Wind variable up to 10 MPH.

FRIDAY NIGHT: Partly cloudy. Fog patches late night. Lows 60-67. Dew point near 60. Wind variable under 10 MPH.

SATURDAY: Partly sunny. Highs 76-83. Dew point near 60. Wind variable up to 10 MPH.

DAYS 6-10 (AUGUST 23-27)

August 23-25 are vulnerable to unsettled weather based on a front just to our south and a trough moving in from the west. I’m cautiously optimistic we finish most of the weekend on August 23 without rainfall and that it’s focused more on the two days that follow, but will monitor the evolution of the pattern here. Trend to fair and seasonable weather later in the period is the current expectation.

DAYS 11-15 (AUGUST 28 – SEPTEMBER 1)

A stretch of mainly fair weather and seasonable temperatures anticipated for the final days of August and the very start of September.

    1. Excellent 3. Mine will register as a 3 but it’s really a 4

      I forgot I use my phone and started with word one on my iPad. I switched to my phone since they don’t sync but already knew a letter from guess 1

      Wordle 4

      1. Nice 4,
        I got ZILCH with my fist guess, a word I thought of last night that I thought would serve me well. I guess Not.
        I was good to still get it in 3. 🙂

    2. I’m joining you in the 3 car today. Had 1 letter in first choice, but 2 in correct position on 2nd with a 3rd out of order.

  1. My Son reported that the high temperature in Scottsdale, QZ yesterday was 112!!!

    YIKES!!

  2. I have to laugh when it is summer and people on X are already cancelling winter. As I said the other day I have low expectations for this winter and I will be happy with one big Nor’easter which did happen in 82-83 which had a strong El Nino and 15-16 where we just missed out on a big snowstorm while the Mid Atlantic got crushed.

  3. Wordle 2 today! First guess had first two letters plus one more out of place, lucky 2nd guess. Would be surprised to see someone else in the 2 car…

    1. Does mine count as a 2 given that I didn’t get any letters with the 1st guess? 🙂 🙂 🙂

    1. You never heard of an eephus pitch? You must be fairly young.
      We used to screw around with that playing pick up baseball games in High School. I never used it in a real league game. 🙂

    2. Never heard the term either which surprises me with all the baseball talk I did hear. Thank you!!

        1. I’m surprised too. But suspect were I listening from a pitcher’s perspective I would know the term . But I was listening to a batters perspective

          1. If you ever played in a slow pitch softball league, you know exactly what an eephus pitch is like. 🙂
            Only difference is in Softball you know what is coming and with baseball, it could be a 95 mph fastball OR an
            eephus pitch. One has to make adjustments in a hurry or else the results could be a disaster.

        1. I saw Ted Williams play and hit home runs, but I never witnessed an EEPHUS pitch live at a game.

  4. Thanks, TK!

    Bill Lee, a left-handed pitcher for the Red Sox in the 1970s and one of my all-time favorite players, used to throw a “Leephus.” He threw a Leephus to the Cardinals’ Tony Perez in the sixth inning of Game 7 of the 1975 World Series. Perez hit it for a two-run homer over everything above the Green Monster. That home run ball still may be in orbit. 🙂

    1. Oops…Tony Perez played for the Cincinnati Reds in 1975. I got the ’75 World Series confused with 1967.

  5. Thank you TK!

    Wordle: Nice job to the 3’s out there. I will be joining the 4 car today and see I have very good company!

  6. 81/68. I’ve been making onion soup which can take hours (not active time. It’s just a matter of getting up and down and stirring things.). But I have to leave the windows open so the house doesn’t smell like onions. It’s all set and just simmering on the stove and the AC is on for at least a little bit of time.

  7. 78/67 here. Waiting to see IF a shower pops. It feels like a sauna out there. It is like swimming through the air!!!

  8. All the talk about Field of Dreams and now you have me
    watching the movie, AGAIN!! for about the 10th time!!!

    LOVE that movie. Sure, pure fantasy, but that is ok to watch now and then.

  9. Another beautiful weather day for visitor’s day at Exceptional Citizens Week.

    Shaking my head a bit.

    I became aware of this week, when I was dating my wife.

    Then, after marriage came our daughters and my wife took a handful of years off.

    Then, all the visitor’s days with my daughters.

    And now, somehow, they are both counselors who each have a camper to care for, for the week.

    Time is magical, but so so fast.

  10. Good afternoon all!

    Expected weather is what we got. Still waiting on any pop-up showers. The chance is there, and there are certainly some solid cumulus along some sea breeze boundaries, but nothing has pushed vertically enough to really get going, other than a brief sprinkle around 2:15 p.m. in Reading MA from one of the darker cloud bases. Classic August weather today. High humidity, but heat not that high. Do not see any lengthy hot spells at the moment., In fact, I don’t really see any short-lived ones either. 😉

    As far as my ongoing forecast, no real changes. I remain optimistic about the weekend (yeah, I know it’s only Tuesday), with a slower-evolving set-up that brings rain to our region early next week (focused on Monday). Weather eyes watching!

    I could say a whole lot of stuff on media’s handling of the Mauna Kea snow event, but I think you all know where I’d go with that, so I’ll spare you today. 😉

    That’s gonna do it for now!

    1. In Pembroke and seeing what you described above.

      Sea breeze boundary, as you mentioned is right around Pembroke (locally), with some taller cumulus towards the southwestern quadrant of the horizon, while it’s completely clear looking east towards the coastline.

  11. P.S.

    Rest in peace, Frank Beard, drummer of ZZ Top.

    Beard, ironically the only member of ZZ Top not to have a beard, had been off the road and out of the studio for a while with declining health, and was on hospice care at his home when he passed away yesterday (August 17) at the age of 77.

    Frank had a backbeat blues & rock drumming style that I, as a drummer, admired quite a bit. During his career he did suffer a period of addiction to drugs and alcohol, but decided enough was enough and left the rock scene with the band supporting him by going on hiatus for nearly 3 years, prior to their most popular period of time, to get clean and sober, and he did, and stayed that way.

    I’ve been a big fan of the band for many years and will always admire the contributions of Mr. Beard. The only original member still with us is Billy Gibbons. Bassist Dusty Hill passed away a few years ago, and knowing he was dying, recommended Elwood Francis to take his place. Francis and Gibbons will continue, with a drummer they have been playing with in Frank’s absence, after a break to mourn his passing.

    1. Oh, I’m sorry to hear of this.

      I saw the other day in the news he wasn’t well.

      I still love 80s music and there’s plenty ZZ Top hits I still enjoy. I think they had some of the better MTV music videos.

    2. So sad to see so many of the rockers from past days dying off.

      Of all people, Keith Richards is still with us. May he live to 100.

        1. Could very well.

          Rolling stones were my favorite band of all time. Saw them at the old Boston Garden in 1965!!
          My friends liked the Beatles, but I liked the Stones.

        2. Mick and Keith, they may both make 100 🙂

          Neat that you saw the Stones at the Garden in 1965.

          My goodness, Bill Russell and co were in the middle of their dynasty then.

          1. Mick Jagger underwent an aortic valve replacement surgery in 2019 and made a complete recovery. I think that event gave him a renewed love for living and celebrating life.

    3. This is indeed sad.

      I remember seeing a double bill of ZZ Top and The Black Crowes in Worcester in the late 80’s. It was wonderful!

  12. Thanks TK.

    It still feels VERY sticky to me outside. This is the part of summer that drags on and on and on. I know it’s not hot. And the dewpoints aren’t that high. But I just feel so uncomfortable outside. Sweaty all the time and really not liking it. Today’s run was brutal. Yesterday was okay.

    1. They are running mid-upper 60s in easternmost MA, so you are correct, it is quite humid there.

  13. Back in June, the Red Sox were 12-25 at home and now they are 31-31.

    TK – How did you figure they would comeback to .500+ early on? During their streak, they had no additions and no hope.

    If I’m not mistaken, that home record was the WORST in MLB.

    1. Simple. I knew enough about the team to know their capabilities, and also have faith and patience.

      They’ve always had hope. It was just a matter of playing better and more consistently, and that often comes with time.
