DAYS 1-5 (JUNE 23-27)

A strong high pressure ridge brings the heat to our region today and Tuesday, though the coast is quite vulnerable to a sea breeze today and will end up cooler than inland areas. One thing we’ll need to watch for are some coastal areas to experience a late-day temperature jump if then sea breeze collapses. Tuesday, if there are any sea breezes, they will be feeble and right at the beaches / shore roads, although some areas of Cape Cod will have a direct ocean breeze due to the prevailing wind, so that area will be cooler by default. There is also some thin high altitude wildfire smoke about, and that will give the sky a hazy look during the next couple of days. Wednesday, a back-door cold front will ease its way across the region from northeast to southwest, and a few 90+ high temps are still possible over inland areas, especially southwest of Boston. It is also this region that stands the greatest chance of a pop up shower or thunderstorm associated with the advancing frontal boundary. Thursday and Friday, our weather will be quite different, with the front sitting off to our southwest. High pressure in eastern Canada will provide a broad scale northeasterly to easterly air flow with a cooler maritime air mass. Disturbances moving along the frontal boundary to our south will bring a lot of clouds and the threat of occasional showers – so an overall unsettled, cooler set-up.

TODAY: Patchy clouds in the hills of southwestern NH and central MA early, otherwise hazy sunshine. Highs 74-81 Cape Cod, 82-89 other coastal locations (some of these may occur late-day), 90-97 inland. Dew point 65+. Wind variable up to 10 MPH with coastal sea breezes, then SW up to 10 MPH by day’s end.

TONIGHT: Clear / hazy. Lows 68-75. Dew point 65+. Wind SW up to 10 MPH.

TUESDAY: Hazy sunshine. Highs 92-99 except cooler a few immediate coastal areas and especially Cape Cod. Dew point 65+. Wind W 5-15 MPH, may switch at times to a weak sea breeze along the immediate coastline.

TUESDAY NIGHT: Mostly clear. Lows 71-78. Dew point 65+. Wind W up to 10 MPH.

WEDNESDAY: Partly sunny. An isolated shower or thunderstorm inland areas mainly southwest of Boston in the afternoon. Highs 78-85 coast, 86-93 inland, but a cooling trend from northeast to southwest by midday on. Dew point 65+. Wind shifting to NE 5-15 MPH from northeast to southwest.

WEDNESDAY NIGHT: Partly cloudy. Lows 63-70. Dew point 60+. Wind NE up to 10 MPH.

THURSDAY: Variably cloudy. Scattered showers. Highs 72-79, coolest coast. Dew point 60+. Wind NE to E up to 10 MPH.

THURSDAY NIGHT: Mostly cloudy. Patchy fog. Chance of a shower. Lows 61-68. Dew point 60+. Wind E up to 10 MPH.

FRIDAY: Mostly cloudy. Chance of showers. Highs 68-75, coolest coast. Dew point 60+. Wind E up to 10 MPH.

DAYS 6-10 (JUNE 28 – JULY 2)

The maritime air mass pattern weakens during the June 28-29 weekend with a reduction in shower chances and slightly warmer weather returning, but still coolest along the coast. A more seasonably warm pattern for the final day of June and first couple days of July, but one front to watch that can bring a shower and thunderstorm chance – most likely July 1.

DAYS 11-15 (JULY 3-7)

High pressure looks like it will dominate with fair and seasonably warm weather around the Independence Day time period, with higher humidity and unsettled weather returning later in the period.

  4. Logsn is at 82 with dp 70.
    About to go to a sea breeze. How high will they get today. Will a late day switch to land breeze bring them to 90? We shall see by day’s end.

    1. We walked this morning from 6:30 to 7:30. For some reason I used “humid” to start Wordle. I got it in four tries.

      1. good job. I didn’t think I would be good at this game. Does not play to my strength. I contimue to play because i think it i good for me. 🙂

    2. I went back to my standard first two words and got a three.

      I also like it because it’s good brain exercise but it’s fun too.

  8. Logsn down to 81 as it has already gone to a SE seabreeze at 6 mph. We’ll see how strong it gets or relaxes or what.

    Meanwhile the whole area is 79-82 and inland areas expected to be in the mid 90s. Here in JP, depends upon how strong and how far the sea breeze penetrates. Today, I am NOT expected much in the way of a sea breeze here. I am expecting low to mid 90s here. Ler’s see how wrong I am.

  11. Up to 78 from a low of 68. 75 DP. My two closest nws stations are eight degrees off of each other again.

  12. Logan is down to 79 while Norwood is up to 88. Pretty much as expected. We’ll see how the whole day shakes out.

  13. Already approaching 90 here at the StormHQ World Headquarters Compound. Had a Dr. Appt first thing this morning and it was 81 when I left the house at 7:45 and 86 when I got back at 8:45.

  14. https://ibb.co/fPCDXbZ

    Was up at the “mini” sea wall once you past through Brant Rock Village and head up towards the Inn and eventually at the end of the road, a campground.

    Anyway, very hazy over the ocean and a light seabreeze causing some small ripples.

      1. Saturday’s was very tolerable, when there was a seabreeze.

        Yesterday, it was frigid with that land breeze.

        Word is green harbor beach (Burke’s beach) is having a seaweed issue (smell), but I haven’t seen that at Avon St beach, which they replenished with an amazing amount of sand that has made it a different beach in that all of it doesn’t submerge at high tide, for now.

  15. Bunch of 90 degree readings in S. NY and NJ.
    Back from the coast going to be a STINKER!!!

    Logan crept back up to 81.
    Norwood 88

  16. Thanks, TK.

    Not thrilled about this weather (well, that’s an understatement as I detest this stuff; everything about it). But it is what it is. Just have to endure it.

    1. Fanuiel Hall area in Boston likely to hit 90F.

      Now, I’m craving walking through there to choose from all the various foods. 🙂 🙂 🙂

  20. Poor inland today.

    Can see the dps rising now into the low 70s inland and I wouldn’t be surprised if they rise into the mid 70s.

    All the evaporated water is just going to hang in the boundary layer inland with little column mixing.

    Ironically, the coast may have, reasonably speaking, the lower dps today in the upper 60s.

      1. Yes, the absolute warmest air aloft passes by about 1, maybe 2pm, so I think that’s why the temp steadies close to 100F just after noon time and then holding there for a few hours.

  23. “Outdoor fun” is often a theme for summer. It’s in advertisements. The media often uses the phrase. It’s hard for me to understand, at least not in hot and humid places. To me, being outdoors – and I LOVE the outdoors – is just not fun on days like today. It’s gross, the air is heavy, it’s impossible to exercise or work out in. Kind of inhospitable.

  25. I heard this morning on WEEI radio that SF is 15-2 in day games at HOME.

    So the Red Sox never had a chance in the previous 2 games. The schedule makers have already spoken. At least they got the opener at night.

    Still, they better get their defense in order!

  26. My early morning run was brutal. The humidity had me sweating within the first ten minutes. Just atrocious.

  27. 81 at the airport with dp 70, wind ESE at 12 mph
    meanwhile it is 91 at Norwood with dp 72

    Pretty thick out there.

    Boston Buoy water temperature: 64.9 reflecting effects of sea breeze.

    1. We’ll have earned a much cooler Thursday after today, tomorrow and a still toasty Wednesday for most.

  32. Dps in central and western mass 73-76F with very little wind and temps a little either side of 90F.

  34. Living the life of luxury at the coast, low 80s and upper 60s dps, it’s like the trade winds in Hawaii.

    Not too far inland, it’s like Miami, Fl

    1. Only maybe a handful of times if that in our years at Humarock did temp stay high. It was heavenly having wind off of water on both sides of the houses.

  36. The media needs to stop inventing scare tactic terms for clicks.

    “Extereme Heat Dome Warning! Millions in Danger!”

    No.

    There is NO SUCH THING as an extreme heat dome warning . Like they seriously need to cut the shit and stop undermining the information from the actual experts. Like now.

  41. Crickets from the media on the cold snap and snow on the west. That’s actually more unusual than the eastern heat.

    Pay attention. Cover it all. This isn’t a cherry tree. 😉

    Yes I’m extra grumpy at media today. 100% warranted. 🙂

  42. Mid afternoon. 80s coast. Lower 90s inland. Some 70s Cape. No surprises.

    And very ordinary hot weather for June.

    Tomorrow’s a bit more intense, but it’s definitely not the “worst ever”. 😉

  44. 84 at the airport,
    90 here
    97 at Norwood
    97 at Manchester, NH
    95 at Concord , NH
    and
    99 at Westfield, MA

    I thinks we can say it is hot,

  45. Looking at the latest 17Z HRRR, it looks to me like there is a good
    chance the sea breeze relaxes or quits allowing Logan’s temperature to rise to 90 or above. Frankly, I think it happens.
    We shall see. Only has to rise 6 degrees from current reading,

    1. something happening here. I think the sea breeze has backed off here and the W to SW wind is creeping in and elevating the temperature. Up to 92 here with Dew Point now 77!!

      Heat index 106

      3 ACs cranking out maximum cooling. (20,000 btus total) 1/2 the house is very comfortable while the other 1/2 is a steamy sauna!!!!

  50. When did the phrase “Heat Dome” start being bandied about?

    Is there any meteorological basis to it?

    Are some heatwaves related to a Hemispherical Atmospheric Structure ( HAS, just made it up 🙂 ) and others not?

    I know I should just ignore it, but I had to search Google news:
    https://ibb.co/39j10qYz

    2. I’m going to guess.

      I think it’s a 3 dimensional view of this very strong ridge, which is accurate.

      When I post and talk about those 500 dm heights being at 594 – 597 dm, it’s identifying the height at which that pressure is being measured.

      So, a strong heat wave, the notorious ones are found near, close by and under a dome of really really really warm air that is quite high into the atmosphere and is shaped as a dome.

      In today’s case, the tallest part of the dome is southwest of us, but we are fitting in nicely into its northeast corner.

    3. The phrase was used among meteorologists in discussing certain aspects of the weather back in the 1990s.

      As is usual, the media gets a hold of our phrases and repurposes them for drama.

      This has now gone on for decades.

      “Heat dome” has become a big one since media has now been told to focus on heat while downplaying cold.

  51. 63F atop mt Washington and 92F at 1,000 ft Worcester and the temps above continue to increase just a bit more.

  52. it is now 93 here, and my dew point sensor is ready 78.
    It has been extremely accurate, but I don’t think this reading is quite correct. Probably 74 or 75. THe sensor is a little too close to the exhaust of a nearby Air conditioner. But then again, the temperature is just fine. So I dunno. Really freakin humid!!!!!

    1. Yes.

      That seabreeze boundary isn’t just a savior from 95F, it’s a savior from incredibly oppressive humidity and unfortunately, you are now on the brutal side of it.

      Watch when Logan switches over later, it’s DP will climb to 75F.

  54. It’s 96F with a 76F DP in Montreal.

    This is bad. I hope people without AC or those who are vulnerable to heat are ok. Anyone at the immediate coast might be like, what ?? But, it’s about as tough as it can get in the northeast inland, mid 90s, mid 70s dps.

    And, as one can imagine, it’s going to struggle to cool down later on.

    2. yup, a real heat dome. Heat domes are real, Heat dome warnings are not.
      I REALLY fear for tomorrow. I think it is almost certain to reach 100 or more. I can feel it!!

      2. A heat dome is a nickname that meteorologists crafted a few decades ago. Mainstream media turned it into a drama tool.

        I was actually one of the first meteorologists to use the term among my colleagues.

        1. It is a nice term and very appropriate. I didn’t care for the media issuing a “heat dome” warning! PATHETIC!!!

  55. How can the seabreeze move away from my area and at the same time intensify at Logan? Logan down to 82 with EAST wind at 20 mph. That is a really stiff sea breeze. I’m surprised logan is that high. Meanwhile We’re at 93.5 just a mere 6 miles away.

    1. Now I am beginning to think Logan’s wind will not shift or at least
      not in time for them to jump to 90. We shall see. There are always surprises.

  60. 45% of the lower 48 sees high temps of 90+ today, June 23 2025.

    On June 23 1988, 62% of the lower 48 was 90+. 1988 “heat dome” for the win. 😉

    Ironically if you take the entire lower 48 today, with the cold out West, the nation’s average temp is about 3°F below normal for the date. Gotta look beyond the back yard for the whole story, which I will continue to do so long as our news sources continue to ignore certain aspects of our weather. 🙂 I did not enter the profession with the intention of half-assing anything. I’ll be the scientist I was trained to be and always strive to be, and that’s what it’s all about. 🙂 Nothing at all wrong with that!

    1. You won’t find this broader and accurate perspective in any mainstream media outlet and very few “new” media sources.

      1. And it’s sad. Why ignore what’s there, and noteworthy?

        Because hot weather “sells” in the summer. Who wants to hear about below normal temperatures and snowfall – that’s for WINTER! But sorry, that’s not how it works. Weather is weather, and that includes anomalous cold and snow as well as summer heat. It’s interesting though that during the winter, they will kind of focus on the coldest of the cold, but still tend to drive harder on anything that constitutes anomalous winter warmth.

  62. Temps currently range from 73 (Nantucket) to 96 (Fitchburg) across the WHW forecast area. Dew points sit in the upper 60s to middle 70s, with a few upper 70s south of I-90. Nice hot, muggy early summer day!

    On this day in 1988, much of the country was BAKING, far more areal coverage than today. However, Boston’s high on 6/23/1988 was a modest 86 (a little warmer than today’s – so far). But they had already hit or exceed 90 degrees SIX times in June 1988, including a scorching high of 98 on June 15 1988 (still spring, prior to summer solstice!) as part of a 4-day heatwave (94 on the 13th & 14th, 98 on the 15th, and 92 on the 16th).

    2. Yes I do remember 1988 summer and it was a HOT one indeed! Far less media hype back then.

      I also don’t recall the Boston Mayor issuing heat warnings/advisories. Maybe he did. Was it Flynn or Menino?

      1. That’s the thing .. far less media hype and no internet. Listen, I’m all for INFORMING about hot weather and its potential effects. Nobody needs to misunderstand me. What I am not for is hyper-focus to the point of MISSING the point, losing the viewers’ ability to get the actual information, and wording stuff in an unrealistic, unnecessary way.

        We have excellent tools now. The use of them leaves much to be desired.

    1. so, it begins. what about dear ole Logan? They’ll keep a sea breeze tille midnight, 🙂

    2. Went to coffee break in Wollaston today Philip as they have the best Ice coffee around

  66. Looks like the sea breeze is about to quit at Logan. Temp back up to 81 and sea breeze has dropped off to 8mph. If it stops soon, Logan will jumpt to 90 or more.

  68. There’s a SW wind push coming up in southeast Mass.

    The 90F line is pushing north and east too.

    It’s at the end of rte 24, where it dumps onto 495.

    Will the breeze switch at Logan before a bit of indirect cooling from the south coast keeps them from 90F. It’s going to be close.

    2. The breeze has picked up here. How long will it take to get to Logan?
      Running out of time for Logan to jump to 90. Can still do it, but needs to happen fairly soon. Still close to 94 here.

      1. At this time of year, about 7PM is the absolute cut-off for Logan to reach 90 from where they are now, unless you really have a good gradient wind and some downsloping. If the wind goes light southerly there by 6PM, they have a shot at 90.

        1. 7PM, ok. I was thinking more 6PM. Fun watching just the same. There “should” be enough push with this SW wind to do the job, but then again Logan can be notorious for holding onto a sea breeze.

    1. what the hay. Airport just dropped back to 79 and dp dropped to 67, THe airport can’t make up its mind. 🙂 🙂 🙂
      funny funny place!!

    1. And it has now dropped to 88.

      What’s with the SOUTH wind all across Eastern SNE?
      If that holds tomorrow, 90 would be about tops.
      Interesting…..

  73. Today is warm and tomorrow hot. Not unusual of course, but listening to the media you would think it’s Armageddon.

    Plan on walking the shore in the AM. Figuring 69-72F for the walk.

  74. People are wigging out about this heat , it’s summer & it should be hot !! Oh my tomorrow is hottter it’s the end of everything !! The only folks I worry for are folks like old salty’s wife ( hope she is ok ) today was nothing !!

      1. I sincerely feel for her & others old salty that have a tough time dealing with this . Growing up on the beach in Marshfield I lived for these days all year long & it’s just my makeup .

    2. And folks wig out about snow. Unfortunately, a lot of proper struggle physically with heat.

  75. So the seabreeze shut off and Boston jumped to 90 at 6pm. I feel like yesterday I read about the possibility of that happening….

    1. I do recall. I think the person posting has a username that begins with capital S and ends with a capital K.

  76. If, in fact, Logan did get to 90 at the last minute, Boston “should” achieve heat wave status this week. It would be the first of the season.

  82. I experienced something cool (or should I say cool to hot) earlier.

    Went to Hampton Beach late afternoon / early evening to feel the sea breeze and look at the sand sculptures – before they get taken down tomorrow.

    The temp there was 77 when I left. I drove down 1A to 286 west toward I-95. Just before I got to 95 I crossed the sea breeze boundary and you could literally feel the temperature jump up 8 degrees over a span of about 100 yard (to 85). By the time I got home, it was 88 here.

    I love days like this. They fascinate me.

    Now we’ll see how many places reach 100 tomorrow (I don’t think many). It will really be the only record heat kind of day of this stretch. Otherwise, it’s fairly ordinary as far as heat spells go.

    Meanwhile the western US remains COLD. I saw a lot of really inaccurate headlines talking about a record heatwave across the country. This is incorrect. I don’t accept incorrect information and am on a renewed quest to call it out any time I see it, and spread the word around social media in an effort to help people smarten up when seeking weather information.

    We deserve to be heard. The folks spreading misinformation do not.

    1. Interesting that it’s high 70s to low 80s in and around Boston and low to mid 70s west of that area. We are 73

  84. Still 82 at the airport. Been that way for about an hour. No rise while other stations are beginning to rise rapidly. Hmmmm
    Not sure what to make of that.

    82 with WEST wind at 12 mph and dew point 73

    How high will it go? Even NWS is saying high 90s to low 100s.

    It is stinken hot in this house. Have to turn ACs on early today to keep up with this heat. HOPE like hell there is no loss of power today!!!!

  86. Logan now up to 84
    All latest models show 96-102 as range of high temps for
    Boston. My money is on 100 or perhaps a tad more.
    I think Boston reaches the century mark. IF not, it will be really close. 97 or 98 is plenty hot enough!!!
