DAYS 1-5 (JUNE 29 – JULY 3)

We finish up June today and Tuesday with a warming trend as a high pressure ridge builds to our west. Sunshine will be initially limited by fog & stratus in parts of southern MA, RI, and eastern CT early today, but that will dissipate leaving a filtered sunshine by both passing high clouds and high altitude smoke, the latter of which has travelled our way in the jet stream from the western portions of North America. Most of this should be driven to our south by Tuesday with more of a northwesterly air flow on the eastern side of a ridge. One other things we’ll have to watch for in the upper flow is a disturbance riding over the top of the ridge and bringing a batch or two of showers and thunderstorms through our region Tuesday afternoon or night. Forecasting the details of these things is difficult, even sometimes in the short-term, so heading into Tuesday we’ll see a trend toward more cloudiness and we’ll have to eye observations and radar to see how things evolve, which could be anything from a few showers and storms to a more general rain / t-storm area passing by. The upper ridge will build eastward as we begin July, and Wednesday through Friday will be hot days here. The position of the ridge should deflect most “over the top” convection to our north, but we’ll still have to keep an eye out for a stray thunderstorm at times. This heat will also come with higher humidity. Those with outdoor plans, work or leisure, should take note, and use caution. We may have to be a bit more alert for a thunderstorm potential by Friday as a slight retrogression of the upper ridge gets underway. I’ll monitor that during this week.

TODAY: Early-day fog / low cloud patches southern areas, otherwise filtered sun with high clouds and high-altitude smoke. Highs 78-85, coolest coast. Dew point near 60. Wind variable up to 10 MPH with coastal sea breezes.

TONIGHT: Mostly clear. Fog patches in low elevations. Lows 60-67. Dew point near 60. Wind variable to W up to 10 MPH.

TUESDAY: Sunny start, then variably cloudy. A shower or thunderstorm is possible afternoon and evening. Highs 82-89. Dewpoint 60+. Wind W 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. A shower or thunderstorm possible early. Lows 64-71. Dew point 60+. Wind W up to 10 MPH.

WEDNESDAY: Partly cloudy. An isolated thunderstorm possible. Highs 88-95. Dew point 65+ Wind W 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. An isolated shower or thunderstorm possible. Lows 67-74. Dewpoint 65+. Wind W to SW up to 10 MPH.

THURSDAY: Mostly sunny. Highs 91-98 except 80s Cape Cod. Dew point 65+. Wind SW to W 5-15 MPH.

THURSDAY NIGHT: Partly cloudy. Lows 70-77. Dew point 65+. Wind SW to W 5-15 MPH.

FRIDAY: Partly sunny. A thunderstorm possible. Highs 90-97 except 80s Cape Cod. Dew point 65+. Wind SW to W 5-15 MPH.

DAYS 6-10 (JULY 4-8)

Watching for a back-door front to cool down at least eastern areas during the July 4-5 weekend, which will not be without a shower and thunderstorm threat, though the highest chance may shift to the west. Trend to more seasonable temperatures into next week with a few shower and thunderstorm chances.

DAYS 11-15 (JULY 9-13)

Overall pattern features west to east flow with a few passing disturbances bringing shower and t-storm opportunities, but no prolonged unsettled weather. Temperatures slightly variable but averaging near normal overall.

  3. Good morni g and thank yiu TK

    70 up from 65

    Ocean: 63

    Wordle: 5. Almost lost this one.

    Re: heat
    Nws point forecast for my area

    We’d 98
    Thu. 103
    Fri. 102

    I guess the NWS doesn’t even use the ensembles?????

    Last night Jeff Harringto, ch 10 had 94 for wed and 100 for thu and fri. Did he split the difference?? NWS expecting heat indexes of 111.

    No matter, looks like 3 very hot days and Tues may even touch or exceed 90 in spots.

    We will feel the heat starting to build today, save for a sea breeze near the coast.

    Here is hoping there is no loss of power!! Last June when it was 102 we lost power and that was bruta!!!!! If we maintain power we have the acs to get through this.

  4. JpDave you are mentioning loss of power I was thinking if one of these thunderstorm complexes comes through on the strong to severe side that could result in power outages. There is no relief from the heat if that happens.

  6. Thanks TK !

    Hot, hot weather coming up.

    A couple weeks ago, Joshua shared a post about his son. Well, in addition to fighting blood pressure, I’m kind of a mess in my head too. This all has thrown me for a big psychological downer and I notice the symptoms, such as withdrawing from things I like. Anyhow, I have support scheduled with upcoming appointments, but if I’m off the blog at times, that’s what’s going on.

    1. Sorry to here Tom. Please don’t withdraw from here. You are an integral part of this blog! you help make it tick. Please stick around, I think it would be helpful for you. Best of luck!

      btw, very nice 4 on Wordle.

    2. Tom my wife has been dealing with BP issues as well as when she goes from sitting to standing her BP was tanking dangerously but has been on a medication that she takes 3 times a day & has indeed helped her . I am sorry to hear all that you’re dealing with but so happy that you are getting the help . If you would ever want to meet up for a coffee some weekend feel free to message me , take care of yourself my friend .

    3. Hi Tom. Sounds like you’re addressing the health issues which is good! Too many people do not. Hoping all goes well.

    5. Nice 4, Tom. I’ve missed seeing your name here. Please do what is very best for you. Also please remember we can be your support system also. Whw is an excellent outlet when you are struggling. Love and prayers are headed your way.

  7. Thank you, TK and SAK. Great posts.

    Tom, praying for a lasting good answer for you.
    (And also for your son, Joshua.)

  9. Good luck Tom. I’ve known people with similar issues that you are experiencing. PCP have prescribed meds that have helped them snap out of the symptoms that you are experiencing.

  10. Thanks, TK.

    Tom, do take care.

    Physical and mental health are intertwined.

    Even though life can be beautiful and wonderful, it has its difficult moments.

    Milan Kundera wrote: “Life isn’t a walk on a sunny meadow.” He didn’t mean that hardships are a permanent fixture in life. But he reminds the reader that burdens exist and we deal with them as best we can. This sense of realism actually helps me through difficult times more than fairy tales.

  13. Hingham’s power went out last night. 2,000 homes on part of the grid without power. No explanation, just off for an hour and a half until about 2am.

    Some mobile apps showing apocalyptic feels like temps. I present to the class the feels like temps for Hingham via “Foreca” as the source: https://ibb.co/39LFQJkq

  14. Thank you TK!

    Tom – thinking of you as you work through this bump in the road. You are certainly not alone.

  16. Hiking and climbing season is here. People always have to be careful. The heat can take serious toll while climbing. There are those who understand the dangers of heat and dehydration. And those that don’t. Yes, it’s cooler in the mountains but once above the tree line, you are exposed.

    There have already been rescues in the White Mountains though not weather related including one a couple of days ago on the Huntington Ravine Trail, one of the toughest in the Whites.

    The best climbers I know have a common trait… they know when it’s time to turn back. They realize the trail will still be there tomorrow.

  17. Quick question: when do people think the worst time for traffic to the Cape will be this week?

    1. have not been to the Cape in many years, but I used to find
      the Friday late afternoon to Evenings were bad, but even worse used to be Saturday AM!!

      Have no idea what the current traffic patterns are.

      1. If I had to guess, DB, it would be Thursday afternoon and evening. With Independence Day on Saturday, the observed holiday is Friday. Many places will be closed on Friday. Most schools are out, so, I am guessing families left last weekend for a vacation.

        I went to a gathering in Wareham on the Friday of Memorial Day weekend and I sailed down 495 without an issue.

        Hope that helps.

          1. Thanks. We are planning to leave Wednesday around noon while my daughter will be on the road early Thursday morning. Hopefully both will work out.

          2. Thursday is the new Friday for Cape traffic. It is very heaving on route 3 and even the secondary roads from Kingston south on Thursdays now.

            1. Thanks Sue. We will be heading down from Natick and have some back roads that get us to 495 and hopefully clear sailing from there. I will pass your comments on to my daughter who will be in your area.

  19. This is not intended to be political. For me it’s wonderful news. I’ll add a link in a comment

    “Former NOAA employees in the U.S. have resurrected 15 years of public climate data on a new, non-profit website.

    After …the popular Climate. gov domain and laid off its staff, former federal scientists have fought back by launching Climate. us.

    Led by former program manager Rebecca Lindsey, the newly debuted independent nonprofit website resurrects 15 years of weather records, climate indicators, and the Fifth National Climate Assessment. The grassroots effort, reviewed by over 80 volunteer scientists, was made possible by more than 2,500 individual donors who raised approximately $250,000 to keep the critical research online.

  21. Tom, I wish you the best of luck. I have had severe anxiety all my life. It’s been on and off through the years. As a child I used to get sick or get panicky just leaving the house. My parents didn’t do much for me – brought me to doctors and they put me on a low-fat diet. I was skinny then. that was the50s. Moving ahead, managed kind of ok in high school and college – some anxieties at times. Managed to get married; honeymoon and a few years of travel. To make a long story short, my husband and me ran into health and money problems – anxiety grew worse. I have been on medication since the 80’s. Now, we both have medical issues and my anxiety is sky high. We both are still waiting for surgeries. It’s been tough. I will pray for you. Just hang in there.

  23. Joshua, praying for your son, also.

    Hoping if we get any thunderstorms during this week we might get a brief cooling at least.

  24. Quick review of latest info.

    No changes.
    NWS #’s IMO are too high. NBM leads them astray quite regularly. Yes, it’s going to be hot. No, we’re not looking at widespread highs of 100 to 105. Pretty much every incoming hot spell these days is treated as the worst one we’ve ever seen. This will NOT be the worst one we’ve ever seen. It’ll be hot. People will need to use care. And eventually we’ll be beyond it. Like every other time. I wish the sensationalism was checked at the door but that ship sailed a long time ago and folks like myself and some of my level headed colleagues are on an island by ourselves in terms of how we communicate the message. Funny too, people usually understand us pretty well. Wonder why that is. 😉

      1. It’s possible, but I’m skeptical of more than 1 or 2 major stations seeing it. It comes down to wind direction for some, as you know.

        1. I guess we will all find out together. With logan’s sensor issues, they’ll probably come in at 105.

          1. We’ll see. I do think their issue this time is only about half that of the last 2. My colleagues and I all agree that they are 1 degree to the warm side on calibration.

            1. I guess they won’t come in at 105. He he we shall see. What do you give them for thur and fri? Like 96 or 97?

              1. Tue: 89
                Wed: 95
                Thu: 98
                Fri: 94 then sea breeze
                Sat: 86 then back-door
                Sun: 89

                1. 0k, thank you.
                  98 is still plenty hot enough as you suggested.

                  I just wish we could stay 70s and 80s all Summer. No stinken 90s
                  But, hey we ave about 14. 90 degree days, so my wish will likely never happen.

  27. Interesting…
    Looks like the Euro came down about 5 degrees for high temps wed thru Friday. Most interesting.
