DAYS 1-5 (JUNE 30 – JULY 4)

Upper high pressure to the west expands to the east to impact our region with hotter weather Wednesday through Friday. The transition day into that set-up is today as a disturbance tracks to our north and its warm front moves across the region later today and tonight. In the evolving northwesterly air flow with this pattern, the disturbance and warm front will generate a thunderstorm cluster that will make a run at our region, but likely be weakening and breaking up as it moves into and across the region this evening / tonight. There is a shower and thunderstorm chance, but I’m not expecting intense storms or severe weather in the WHW forecast area. During the Wednesday through Friday period we see highest heat and humidity in the region, and will also still have to keep an eye upstream for “ridge rider” shower and thunderstorms or their remnants. The overall set-up does produce a rather strong cap in the atmosphere that may limit the ability of storms to survive the trip across our region, or develop around here. However, it’s borderline, and storms cannot be completely ruled out on any of those days / nights. Our transition day out of the hot spell appears to be Saturday, July 4, when there is a better shot at a passing shower or thunderstorm as a cold front drops through the region from north to south. At day 5, the confidence on timing of this front is not high, but I am leaning toward the first half of the day for a frontal passage over later on. This may also limit the ability for storms to be stronger, but could still impact some outdoor plans. Obviously this will be closely monitored. Behind the front I’d expect a wind shift to north or northeast in response to high pressure in eastern Canada, and this would provide heat relief.

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

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

  2. Good morning and thank yiu TK

    70 up from 64. Dpv72

    Ocean: 64

    Wordle: FAIL

    HEAT and HUMIDITY is coming. I hit the DETEST button.

    IF LOgan can stay away from a sea breeze, I would not be surprised if they hit 90. I AM expecting something like 87-89 here. We shall see.

    Will Boston hit 100 Thurs and/or Friday? TK says no, some Mets and nws say yes. Stay tuned and we’ll all find out. Would not surprise me in the slightest. I do not expect 100 here. Too many trees!! I! I suspect we’ll top out at 98 or 99 Here. We shall see.

    Fwiw even the Euro has Boston awfully close to the century mark even for Saturday!!!

    I really hate this kind of weather coming up. Can we fast forward to Sunday please.

    1. I hope your wife will be ok and has been doing ok in this very warm June we’ve been having.

      1. Not so well and she is going into this heat already feeling lousy from the 60-65 dps we’ve had for almost a week already.
        We’re prepared for a power outage. Car is tanked up, We’ll just drive around until the power comes back on. Worse case, we’ll get a hotel room! This should NOT have to happen!!!!!

        it is 2026!!! One would think that a modern power grid could handle this, but NOPE!! Not when the power companies are totally and completely INCOMPETENT!!!!!! Money goes to share holders INSTEAD of proper maintenance. So when does equipment fail? Under instances of strain on the system which 100 degree heat certainly does. Sorry, end of rant!!!

      2. How are you feeling Tom? Hopefully better. Nice to see you here this morning. Feels like old times.

        1. Thanks JpDave !

          A little better, mentally.

          Best night of sleep in a long time.

          Actually looked at climate data and saw Logan is +3.8F for the month of June and looked deeper into the models and saw the 500 mb heights and 850 mb temps through Saturday, so that’s the first time I’ve done that in a couple weeks, so, that’s something I haven’t done in a few weeks. Baby steps 🙂

          1. Nice to see you here Tom . Baby steps one Dat at a time , I hope you have a peaceful day today my friend .

  4. Thanks TK !

    Wordle: 6

    I had the first, second and fifth letters in the correct spots and then used a couple guesses with the wrong variations. Got lucky with the 6th guess that it matched.

    1. Great. I had ZILCH with 1st 2 guesses then got a couple out of position then 3 in position with the 4th guess, but I was not lucky with my guesses and did NOT get the correct word.

  5. Thanks TK.

    At least this “heat dome” has been taking its sweet time getting here…problem is it will take forever to LEAVE!!!

    I have been hearing Monday will be the day of departure.

    1. Hopefully sooner than that. I heard that it purchased a ticket out of here for late Saturday/Early Sunday. 🙂

  9. I’m either joining the 6s or JPD. Feels like a few days ago. I have two letters in correct place after 5 and no clue.

  11. JPD you are right about the grid. It’s more corporate America again. I’ve said before that the company Mac and I worked for for decades had 98% of the electric utilities in North America as clients We produced test sets for monitoring equipment. We worked with all of the utilities on timing for testing and training. We of course kept records that are decades long of the test schedules. Back then the utilities would test regularly. That changed maybe a couple of decades ago. Corporate began to put further and further space between testing and of course, when you don’t test things fail.

    1. So true. I had a boss like that and I was always fighting with him.
      It eventually cost me my job.

      The just do NOT want to spend money that comes out of the bottom line. They simply will NOT allocate proper monies in the budget for true maintenance. They won’t do it.

      Result: unnecessary outages at the worst possible time affecting public health and safety. You think they care?
      NOPE, not in the slightest!

      1. Well said. You’d think they’d realize that in the long run, it costs more money and the loss of clients

  13. The gradient is still rather weak today, so as a result Logan STILL has a light sea breeze. Will it shift on land later? who knows. I suspect it will, but will it be the classic 5 PM shift and will it be enough for them to reach 90. Not looking likely at this point.
    Will monitor throughout the afternoon. 🙂

    75 at logan. 81 at Norwood.
    I am showing 83, but there still might be a bit of a reflection issue for about another 1/2 hour or so, then I should be good.

  14. Thank you TK!

    Tom – so glad to hear you had a good night’s sleep. That is so important for physical and mental health. Hope it continues.

    Wordle: Toss a third line, I busted!

  15. Logan is 70 with a sea breeze. I think it points to how much this air mass is heating up.

    I have 84, dp 67 here!!! YUCKADOODLE!!!!!!

  16. Today the 2025-26 winter (snow) season ends!

    Final total (Boston/Logan) = 62.8” 🙂

    Of course now who knows what El Niño will do this upcoming winter?? Feast or famine?

  17. Early call less snow next winter than last winter. I was not at all disappointed with last winter.

    1. Being off JJ I enjoyed being home for the big storm . With that 30 inch one I had two trees come down out in the pool area that I did not know they fell until springtime , there being removed on Friday ( 2 pines )

    1. 85/67 here and really feeling it. Can’t wait till Thurs and Fri!

      NOT! NOT! NOT!

      We’re chugging towards 90. We shall see if we make it.

      Can you say 5 day heat wave?

      Oh wait, no way Logan gets to 90 today. Not unless the wind shifts soon enough.

  20. Fitchburg is 88 already and Manchester is 86 while Chicopee
    is 87

    Logan is still at 77 with a sea breeze

  21. Our dp dropped from 67 back to 64 only to creep back up to 65.

    We have all 3 ACs cranking.

  22. Logan jumped up to 82 with an ESE sea breeze. Air mass is getting warmer, that’s for sure. Noticeable difference today over yesterday.

    Norwood up to 88. Up to 86 here.

    1. 88s showing up all over the map from MesoWest.
      It certainly looks like a fair number of stations reach 90 or better today. I am literally scared about the next several days!!!

    1. All I know is, sometime during the evening broadcast. I don’t know which one though.

      6 or 11?

    1. 90 at Orange, Fitchburg and Chicopee

      82 at the airport which maintains that sea breeze. It was briefly up to 86 there.

  34. JpDave thanks for posting that. Great satellite view of that thunderstorm complex coming into Upstate NY.

      1. I was being sarcastic when I said I wonder what this could be. 🙂 🙂 🙂 I was very much aware of exactly what it was. 🙂 🙂 🙂

  36. Yes those are those ridge rider thunderstorm complexes that were talked about late last week that go around the heat dome. Will see if it holds together moving to the southeast and if western parts of SNE get impacted by this thunderstorm complex.

  37. Back down to 88 (87.6) and when we were at 89, it was 88.5
    Does NOT look like we make 90 here as there is just too much cloudiness now.

  39. Not for nothing, but there appears to be a bit of a N/S line of storms forming out by Springfield. Check link above.

  41. Wind shifted to the South and Logan jumped to 88!!!

    Will they make 90? Likely not. Just not enough sunshine as there is too much cloudiness out ahead of those storms.

  42. JpDave I am thinking that is why for the outlook for today the SPC extended the marginal risk in case that thunderstorm complex holds together.

    1. Agreed. We shall see what hold together, but then we have action way out ahead of that as well.

  43. You were mentioning about the activity near Springfield new severe thunderstorm warning until 4pm 60 mph wind gusts quarter size hail.

      1. It still has 75-80 miles to go, BUT if it holds together, it still looks to likely pass a bit South of my area. Perhaps I;ll be able to hear some thunder???

  45. The other thing hopefully no loss of power should a thunderstorm hit your area.

  46. Headed up to Ellsworth ME, won’t be quite as hot.

    Wordle 6, similar story, 1, 2, 5. Had two options for last guess and got lucky

    1. I’m under the southern edge of that one. Not home but about one mile east of there at the moment.

    1. Thank you, JPD. I quickly headed to my daughters when I saw storms were starting to pop. I made it back home just ahead of rain. Lightning pro picked up a couple bolts of lightning but nothing I coul hear. 0.22” in 8 minutes still light rain but more on its way.

  50. 84/72 and pouring. Not quite as windy as it was.

    West sutton already lost power. I’m charging everything. Set fridge temps down and making ice

    1. Yikes. And it is Always nice to see you. The second round looks to be falling apart here

  52. Thank you Vicki, I’m very often here lurking.
    In the last 25 minutes I’ve picked up .98” of rain with a max rain rate of 6.22” per hour. Won’t need to water the flowers today.

  53. 85/69 getting darker, but I don’t think anything happens here. Approaching convection is dying. Perhaps something else up stream??

  54. BHO was hit by vandals last evening with many windows broken by rocks. Thankfully, the 141 years of weather information was not damaged, nor was any equipment.

    State Police are investigating and looking for suspects.

    The observatory will be in need of costly repairs and also will be installing a new security camera system, but will need help to pull it off.

    Many of their upcoming events are cancelled or postponed until repairs and upgrades are made.

    1. So sad. What posses someone to do something like that.
      I will never understand it! SCUM OF THE EARTH!!!!!

  55. I was just out to retrieve my recycle bin and I swear I saw
    some mammatus clouds. Not the whole sky, just a small portion of it. Probably making something out of nothing

    1. You’re likely to see some on the anvil canopy of the MCS, even if it’s weakening.

  57. I have to keep track of that daily high temp forecast for Logan I made yesterday and posted to JP Dave.

    Today I went for Logan to top out at 89.
    It looks like their max is going to come in at 88.

  58. Thanks TK! Been on vacation this week and relishing this weather. Fascinating to watch MCS travel all
    The way from midwest only to die along the South Coast! Ha! The heat hypers are alive and well. My gosh.

  59. Storms never made it to Quincy, although it did get fairly dark. Probably just missed and wonder if they made it to Boston-Logan either.

    So far this season (as well as spring) storms always pass just north or south of Boston/Quincy areas. Can’t catch a break during this drought. Oh well.

  60. What an awesome send off for Mike . He was emotional & all of his family was there . He’s just a regular good guy & excellent met . I hate when my people leave ch 5 as I’ve watched so many over the yrs .
