Thursday Forecast


Transition day today as a cold front crosses the region. It will still be rather warm and humid especially through early afternoon and the front may trigger a few showers and thunderstorms as it crosses, first to the northwest, then later toward southeastern MA and RI, and by evening you’ll notice a cooling/drying process underway. It will never get bone-dry as the air will be coming from the northeast due to the orientation of high pressure to the north. But in comparison to recent weather, it will be very refreshing and in full effect through Friday. The Labor Day Weekend will feature a slow transition as this high slips to the southeast, starting on the cooler side Saturday and turning out quite warm and more humid by its conclusion. Forecast details…
TODAY: Variably cloudy. Scattered showers/thunderstorms. Humid. Highs 84-92, cooler Cape Cod. Wind NW shifting to NE 5-15 MPH.
TONIGHT: Mostly cloudy. Less humid. Lows 60-67. Wind NE 5-15 MPH.
FRIDAY: Partly sunny. Highs 72-78. Wind NE 5-15 MPH.
FRIDAY NIGHT: Mostly cloudy. Lows 59-64. Wind light NE.
SATURDAY: Mostly cloudy. Highs 68-75, coolest coast. Wind light NE to E.
SUNDAY: Partly sunny. More humid. Lows from the lower to middle 60s. Highs from the middle 70s to lower 80s.
MONDAY – LABOR DAY: Partly cloudy. Humid. Lows in the 60s. Highs in the 80s.

High pressure dominates surface and aloft with mainly dry and warm to hot weather September 4-5 followed by a transition similar to this week to cooler weather during the September 6-8 period.

DAYS 11-15 (SEPTEMBER 9-13)
High pressure dominates and the pattern of above normal temperatures and below normal rainfall is expected to continue.

    TK, thank you again!

  2. Oceanair says:

    Thanks TK.

    Hoping for a better sleeping night tonight (no A/C). The change in air will be most welcome.

  3. Vicki says:

    Thank you, TK. Hope you are feeling much better

  4. JimmyJames says:

    Thanks TK.
    In the something to keep an eye on category. Tweet from meteorologist John Homenuk
    The ECMWF EPS have backed off significantly on the +AAM and retrograding mean ridge anomaly in the USA through Week 2. With potential for tropical activity from AEW’s and perhaps development near the US coast, this synoptic pattern bears close monitoring.

    With that said, while nothing has developed yet, our best ensemble guidance is pointing to a notable increase in tropical activity – so keep a close eye on the forecast if you live in the Caribbean or US Gulf/East Coasts. More info sure to come in the days ahead.

  5. JpDave says:

    What’s with the NW wind all over SNE?

    The front itself appears to be draped across far NNE.

    Front looks like a WIMP!

    And re: forecast for next week? DIGUSTING!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  6. MassBay says:

    Thanks TK.


  7. WxWatcher says:

    Thanks TK.

    I think JPDave said it best: today’s front is a major wimp. It was a very sharp boundary a few days ago, but it’s washing out now. Today’s a hot day, and then we’re looking at two days of tepid relief before a new heat dome starts to build. The beat goes on. Maybe a pattern change mid-September?

  8. JimmyJames says:

    The AC’s will be getting plenty of use the first full week of September.

  9. Marjie says:

    Thanks, TK.

  10. Marjie says:

    Wasn’t there a movie called “The Long Hot Summer?” I believe there was – I think Paul Newman was in it. I also believe a re-make has been made. It’s called the long hot summer of 2018! :)

  11. Tom says:

    Joshua, Philip and all without A/C …. I have an extra appreciation for what you go through in this hot weather.

    We are dry camping. No electric hookup, no AC running.

    It is tough !

    • Coastal says:

      Why don’t they have AC? Is it by choice or a different reason?

      I should have three window AC’s freeing up for next year if anyone is in need?

      • Vicki says:

        I think affordability is a big reason for some. I’m struggling with the monthly cost. Also electric setup. A lot of older homes have older electric systems

        • Coastal says:

          I can see the electrical load being a issue by the newer, smaller ones don’t draw nearly as much and will do the trick in a small bedroom.

          • Vicki says:

            I figure whatever the reason, it is based on sound judgement, which most of the folks here have, and knowledge of their home.

  12. JimmyJames says:

    I would say its been more the humidity this summer than the heat with the amount of hours this summer with 70 or higher dew points. To me we only had two spells where we dealt with the heat and humidity together. First few days of July and the last two days.

  13. JimmyJames says:

    What you said to me Tom is the big story of this summer. Dew points low to mid 60s is not great but is tolerable. When you get into 70 or higher dew points that is a whole different ball game.

  14. JpDave says:

    Logan up to 88, but Dew point is down to 68 with NW wind.
    Another 90 degree day appears to be in the cards.

    Are lower dew points leaking into the area already? If the front it to our
    North, then why are our winds NW? Shouldn’t they be SW ahead of that
    front? Weird.

    • JpDave says:

      This would make 20? I believe.
      A few of them are fake (ie temp was really 88 or 89), however since
      the records are kept at the facata airport, some days the rest of the city
      was 90+ but it never made 90 at the airport, so 20 sounds good.

  15. JpDave says:

    Logan has reached 90. Of course NO other reporting stations have reached 90.
    Interesting, eh?

  16. JpDave says:

    It’s ONLY 64 at Burlington, VT.

    Where is that air??? Being thwarted by the big bully HEAT DOME!

  17. JpDave says:

    Norwood has reached 90.

  18. JpDave says:

    It’s 84 at Lawrence and 79 at Orange, so there is some cooling near by. Let’s get it
    in here!!

  19. Philip says:

    Dewpoint days 70+F to date = 40 (a new record)

    I suspect the 30 days of 90+degree days at Logan (1983) is well within reach unfortunately. They now have 20 so far with many more to come next month.

  20. JpDave says:

    Logan has dropped to 87. It appears the “cooling” has commenced, however
    much that is.

  21. Tom says:

    On weather underground radar loop, can see ….

    1) a boundary inland, sinking south, probably with a wind switch to NNW

    2) just northeast of Boston, a boundary sinking southwest, probably with a wind shift to NNE or NE

    3) down here on Cape Cod and up off the north shore, some showers trying to develop.

  22. vicki says:

    Temperature variations occur everywhere. I can tell you almost to the tenth of a mile, as I drive back roads from my home to Sutton Center, where the temp will drop 2 or 3 degrees, go back up 2 or 3 degrees, and then drop again. FWIW I do not use the car thermometer alone. During the season, it is clear from growth, ice accumulation, etc.

    I can do the same from my daughter’s home in an area of Uxbridge that is at a lower level to a higher area. The temp swing then (between 5-6.5 miles) varies up to 4 degrees.

    As you can see, I find ways to amuse myself while driving…..other than looking at scenery which I’m not support to do while driving anyway.

  23. JpDave says:

    Logan is at 91! !@*#Y*(!@#*(!@&#*(&!@(*#&!(*&

  24. JpDave says:

    As per what Tom predicted, Logan’s wind just shifted to the NorthEast.
    Beverly already down to 82 with NE wind. YEAH!!!!!!!!!!!!!!!!!!!!!

  25. JpDave says:

    Logan now down to 81!! HOORAY~!~!~!~!~!~!~!~!~!~!~!

  26. JimmyJames says:

    I could feel a big difference compared to 24 hours ago.

  27. JpDave says:

    Cooling has arrived at my house. Down to 84.

  28. vicki says:

    Down to 87 here but 76 in York Maine!!

  29. JimmyJames says:

    A couple days of relief to look forward to. Labor Day going to feel like 4th of July and I would imagine if current forecasts hold were going to be seeing early releases for schools next week.

  30. Woods Hill Weather says:

    Very sharp boundary kicked off a lone tstorm near the S Coast. Temp at my friend’s location near the MA/RI border want from 88 to 77 very quickly.

    • Philip says:

      DPs still oppressive though. :-(

      • Woods Hill Weather says:

        Most areas are under that threshold now. Only the South Coast carries dew points near or over 70 at this point. It seems a lot of folks were expecting some big blast of cool/dry air to immediately arrive. This particular front is not that sharp, though it does represent a rather significant change in both dew point and especially temperature, but just taking place over a period of time.

        • Jp Dave says:

          dp still 69 here. yuck!!!

          • Woods Hill Weather says:

            It was never expected to go down that quickly.

            I know I certainly did not indicate a “blast” of dry air. We have to actually wait for the air mass to fully change before it’s significantly noticeable. This process is ongoing now, but it’s a slow one this time because of the orientation and speed of the front.

          • Jp Dave says:

            make that 68

  31. Jp Dave says:

    The last few days have been
    a tale of 2 shities, temperature and dew point.

  32. BlackstoneWx says:

    I guess I’m the only one on here who loves and enjoys this weather and wish it would continue into October.

    • Vicki says:

      I don’t mind it one bit and there are others who do not as well. But then we have AC, etc. You accept the challenge yet?

      I also enjoy the change of seasons. It is all awesome

    • Woods Hill Weather says:

      I enjoy it but I just do that when it happens. I don’t weather wish anything. :)

  33. WxWatcher says:

    This is a good tweet from Eric Fisher from last night. I’m not a fan of certain aspects of his style but I do like how he isn’t shy about discussing climate issues.

    A friendly, periodic reminder that what we’re experiencing today is not normal. I’m not talking about this late season heat wave or the next one on the way next week. That stuff happens now and again. I’m talking about that graphic I linked to, and the fact that the same principle is true for the globe as a whole. Just because we take absolutely absurd statistics like that for granted these days does not make them any less impressive nor alarming. We are in a fundamentally different climate regime than we were 100 or even 50 years ago. Not trying to start a debate here, but like Eric I’m not shy about discussing these issues and presenting the numbers. As a scientist I feel it’s important people see these numbers. What they choose to think or do about it is up to them.

  34. Vicki says:

    Still 82 in Sutton. Darn near on the boundary

  35. Woods Hill Weather says:

    A little perspective. There have been over 40 days this summer in Boston that have registered a 70 or higher dew point. The previous 3 summers, this number was below 20.

    It is very important that this stat NOT, and I repeat, NOT, be automatically attributed to long term climate issues. Those types of things are identified by trends, not spikes. This is more like the persistent pattern of February 2015 that gave frigid temperatures and 4 powder snowstorms for such a large portion of the region. That is a stable weather pattern, or one that persists. If a pattern such as that is attributed to long term change, it has to be identified as a series of events, not one spike.

    And before anybody takes this wrong, it’s not an anti-climate-change argument, it’s a data analysis and interpretation point. This is important. Period.

  36. Woods Hill Weather says:

    This has been the quietest day in the last 2 weeks for discomfort related to my ongoing health issue. This is a good thing.

    Heading to a fireworks display in Dracut. Good evening all.

  37. matt says:

    Past 20 years, Global temperatures have increased and the increase is increasing. Increasing heat in the air means increased ability to hold H2O, its basic science. CLIMATE scientists have seen the correlation. So yeah maybe this one time might not be at this one location but look at the entire picture its as clear as can be if you can not see it your blind and not willing to look at the science. They have done climate depictions of what the climate would be like if there was no human influence. The difference is huge. Heat waves and humidity indeed become less potent and shorter. Extreme cold in the mid latitudes are not so short yet not as extreme. Its of course not one time, but the increase in occurrence, the increase in extreme events. The west being on fire every freaking year to a point that everyone gets smoked. Come on open your eyes.

    Now here is an article that I feel like everyone should look at, pay especially attention to the graphs, and I mean all of them.

    In other news, going to Wachusett to get some skis hopefully tomorrow, as my dad wanted to come with.

  38. Woods Hill Weather says:

    As I said above, my statement was not an argument on climate itself, just how we look at data. That is very important.
