DAYS 1-5 (JUNE 25-29)

The extreme heat of yesterday will not be repeated today, but don’t let that fool you into thinking we can’t have one more hot day in the stretch. That will be the case because the relief-delivering cold front will take much of the day to traverse the region from north northeast to south southwest – quasi-backdoor style. While some areas reach or exceed 90 again, the record highs of 92 in Worcester, 95 in Hartford, 97 in Boston, and 98 in Providence, all set in 1943, will remain unbroken. A few pop-up showers and thunderstorms can occur today ahead of and along the frontal boundary, but coverage should be fairly low. Any locations that do see them, however, can experience heavy downpours and a pretty solid thunderstorm. The NH Seacoast, southeastern NH, and northeastern MA will be the first to see the temperature rise halted and reversed at some point this afternoon, with that trend then progressing south southwestward with time, so that during the course of this evening everybody is dropping to cooler levels than last night’s low temps. The dew point trend will also be slowly downward into and much of the way through the 60s as the front crosses the region. Our weather pattern is then quite different for the upcoming few days – Thursday through Saturday, dominated by clouds, below normal temperatures, and occasional shower chances, although it will be rain-free far more often than raining in any given location. Shower activity looks like it will favor areas south of I-90 Thursday, be least present Friday, and then another area can progress from northwest to southeast across the region during Saturday. Forecast tweaks upcoming as needed. Sunday’s trend is to see the front to the south lift northward but also lose identity, with a sun/cloud mix here, a warm-up, moderate humidity, but still a shower chance.

TODAY: Starts sunny, then a sun/cloud mix. Isolated to scattered showers and thunderstorms midday and afternoon. Highs 87-94, hottest inland areas, then a cooling trend from northeast to southwest this afternoon. Dew point 65+ but with a slight downward trend from midday on. Wind variable to NW up to 10 MPH, shifting to NE from northeast to southwest by late-day.

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

THURSDAY: Mostly cloudy. Scattered showers. Highs 68-75, 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 a shower. Highs 67-74, coolest coast. Dew point 60+. Wind E up to 10 MPH.

FRIDAY NIGHT: Mostly cloudy. Chance of showers. Fog patches. Lows 60-70. Dew point near 60. Wind SE up to 10 MPH.

SATURDAY: Mostly cloudy. Chance of showers. Highs 70-77. Dew point 60+. Wind SE up to 10 MPH.

SATURDAY NIGHT: Variably cloudy. Chance of a shower. Patchy fog. Lows 60-67. Dew point 60+. Wind SE under 10 MPH.

SUNDAY: Partly sunny. Chance of a shower. Highs 76-83. Dew point 60+. Wind S 5-15 MPH.

DAYS 6-10 (JUNE 30 – JULY 4)

Fair, warmer to finish June. A cold front brings a shower / t-storm chance July 1 with a brief heat spike. High pressure builds in with mainly fair weather July 2-4 with seasonably warm weather.

DAYS 11-15 (JULY 5-9)

Watching a trough and potential unsettled weather at some point early to mid period before fair weather dominates later in the period with high pressure in control. Temperatures near to above normal – no extremes indicated.

  5. Good morning and thank you TK

    8:26 AM and it is already 88 at the airport with dp 70

    I don’t need another day of this CRAP!!!!!!

    1. Totally agree, JPD. I abhor this weather. Can’t wait for the cooldown. Hope you and Mrs. JPD are okay.

      1. I Concur and thank you. The Mrs. was pretty sick yesterday and going 3 1/2 hours without power didn’t help matters.
        I can’t wait for this crap to be gone!!!!!!

  7. Houlton, ME dp 55
    Millenocket, ME dp 52

    So, the dry air is up there. How long will it take to get down here?????????? Answer: TOO LONG!!!!

    1. It could well be.

      One thing that gives me pause though is on the CFS weeklies, Alaska and other northern locations that have been quite warm many of the recent summers seem to show below avg temp outlooks.

      And, to me, I equate that to lower than avg pressure at 60N or higher latitude and thus, under that should be higher than avg heights at 500 mb in the mid latitudes.

      Last August, it was crazy hot in northern Canada at 60N and higher latitude with a Rex block and under that was a suppressed mid latitude jet with all those low 80F days and low humidity. I’m not sure we get a lot of this upside down jet stream this summer. It might be a good old fashioned cold arctic circle, warm to hot mid latitude summer, which would be great for the health of the arctic sea ice.

  10. Summit of Mt Washington down to 54F, it was 59F several hours ago. 1,000 ft Worcester is 82F and temps in general are holding steady or only inching up.

    So, cooling above slowly and that helps a bit.

    Part 2 will help the coast in a few hrs

    And part 3 will be a slow influx of that drier air JpDave noted above.

    Hang in there.

  11. Light at the end of the tunnel. Enjoy the break for a couple days after today.

  13. Nantucket airport with a 90F.

    That NW flow is prevalent today all the way past the south coast and it’s delivering the warmth to Nantucket.

    1. Wow!!! And now Logan is at 90 and Norwood to 91 !!!

      Pretty impressive for 9:19 AM!!!!!!

    1. As you all know, one way for me to stay sane during these hot spells is to read about places where it’s currently cold and snowing. It gives me hope.

      1. I mentioned I’m dreaming of snow yesterday on FB. While I found yesterday fascinating to follow, I didn’t feel well most of the day …heat related and not illness. So I understand exactly where you are coming from

        Christmas BTW is six months from today ❤️

  20. Still feels awful out there to me. I’m going to show up at south shore kid’s house in his pool.

    I registered to run 4.5 miles in hingham’s road race for the 4th of july morning. Here’s hoping it’s not humid. That makes running so terrible.

  22. 12z HRRR, the real change per its simulation happens about or just after midnight.

    At that point it’s mid 70s in southern New England with mid 60s dps.

    4 hrs later, it’s in the mid 60s and the dps are below the mid 50s with some upper 50s showing up.

    And then tomorrow, the temps don’t rise much with onshore flow and 2 layers of clouds above, lots of low clouds and some mid/high clouds above them.

    Midnight tonight temp and dp

    1. The 12z NAM is very similar with warm, humid conditions up to that midnight hr in southern New England and then cooling temps and a dramatic DP drop btwn midnight and sunrise.

      Of course, if one is further NE in NH or ME, all that happens a little bit earlier.

  24. https://ibb.co/WptyNKdw

    Gloucester’s wind is NE, that might be an outflow boundary from the Portland me showers ?

    Anyhow, Marshfield is NNW wind which is an indirect seabreeze off of Massachusetts bay. Logan hanging in there at a NW wind.

  25. How’d everyone do on Wordle? I’m stuck after four. For ages, I was able to complete Wordle two to maybe 10 minutes after midnight. Now I seems to be putting the partially completed game aside till morning or even afternoon

      1. Connections and I have a love hate relationship. Unlike Wordle I often give up after a couple of guesses. I do play boxed occasionally too

        Did you ever try nerdle?

  26. Logan is up to 93. Precisely what an earlier HRRR predicted for
    this time. Interesting….

      1. Oh I know, I was just referencing some accuracy with the HRRR regarding predicted surface temperatures. 🙂 🙂 🙂

  27. Was in Pembroke, 94F on a street bank thermometer by my school campus.

    Can feel a small cooler difference now in our neighborhood and the wind is clearly coming off the ocean.

    I see Logan’s wind went SE and it’s 82F.

  28. Logan has suddenly switched to a SE sea breeze???
    Is this the edge of the back door? Or just a regular sea breeze.

    Their down to 84

  29. Summit of mt Washington has stabilized to 55F and its 88F at 1,000 ft Worcester, so, if not for yesterday, this is still a very warm airmass today.

  30. Vicki, hope you’re feeling a bit better today. The heat will ease soon, quite a bit. It’ll feel a bit like September tomorrow.

    And yes, Christmas is precisely 6 months from today. I never wish time away (it goes by too fast as is), but the holiday period will always be my favorite time of year.

    1. Thank you. I am somewhat improved. But it’s no more than a nuisance. I hope you are also improving

      I agree re wishing time away, but also like you, it is always my favorite time of year.

  31. The air temp at the buoy 16 nautical miles out in Boston Harbor is 77F with a sfc water temp of 67F, so shouldn’t be much more of a drop along the coast below 80F or low 80s this afternoon.

  35. What????? Norwood is up to 97!!!
    While Logan is down to 82
    Last I looked here, we were a bit over 90 like 91.2 or so.

    2. 1,000 ft Worcester airport is 90F, an official heat wave at 1,000 ft

      Mt Washington is 57F

      Except for the coastline, everyone is 90F or a bit higher.

      Sometimes trofs are slower to lift out, sometimes ridges are slower to break down. Even a slight difference can make that transition day a little warmer than expected.

      72 hrs ago, today was not slated to be this warm on most, if any models.

  36. Mefford (sometimes called Medford) has a 103. It looks to be on the Tufts campus when I zoom on.

    1. Hmmmmm That’s is exactly the time the temp went up here. It went up another degree then also to 97

  38. Ok the sensor fell and landed on something hot like cement.

    No way it’s 95F at Logan with a NE wind.

  42. Interesting Logan temp, Tom, at 2:50, 2:54,2:55

    It seems the sensor has been too close to surrounding areas to have a problem. A plane close by?? Or …..

    Also What does the (x100 Ft) header mean?

    https://ibb.co/v4Hg0cLD

    2. On the clouds that means multiply those numbers by 100 to get the cloud heights.

      So 130 scattered for example means scattered clouds at 13,000 ft.

      Yeah, the sensor over there the last few hrs has had some interesting.

      To me, the Logan high is 93F in the 10 o’clock he this morning.

      1. Makes sense as that 10 degree jump looks inaccurate.

        And I know the wind direction influence there as opposed to here is vastly different. The only thing that gives me pause about the earlier jump is that we jumped up two degrees and pretty soon after we dropped back down at basically the exact time Logan did

    1. Nice !

      Happy for anyone who gets rain today.

      Around marshfield, the lawns are now showing majority coverage of stress due to this heat wave.

      We need some rain, preferably gentle rain.

    1. I was notified five minutes ago that heavy rain would start in five minutes. We just had a one minute heavy downpour. No lightning detected yet. It may have weakened just as it reached me. Darn

          2. And now back down to 87. It’s a crazy temp day for sure I know my readings are not inaccurate as I have four sensors telling me the same thing (one is Nws, two kestrel and one accurite).

    1. I hit the like button! The A/C in my car decided to stop working and my mechanic can’t fix it until Monday. It has been rough few days!

  46. Interesting stat from yesterday.
    From Meteorologist Ben Noll
    Baltimore’s Inner Harbor was the hottest location in the Northeast on Tuesday, reaching a gaudy 105.1 degrees.

    It hasn’t dipped below 87 degrees the last two nights — a June record.

    That’s the same as Dubai in the Persian Gulf. Baltimore is currently the Dubai of the Northeast.

    1. Even what happened yesterday in BWI is no comparison to typical conditions in most of the Persian Gulf region. The one cherry picked location is not really representative.

      I used to forecast this region daily when I worked in the private sector. 🙂

      The thing is … the MSM loves to play on this “always hotter in the South” idea, which is simply NOT the case. There are reasons why Tampa, for example, has not hit as high a temp as Boston for all time records. They need to study the earth and its weather / climate a bit better.

      With this particular pattern, it was about the location and magnitude of upper high pressure. My colleague and I were saying ahead of time that this was going to be a very “Northern” hot spell. We can see them coming. And just because it’s “wicked hot” in the North, doesn’t mean it needs to be “wicked hotter” in the South. That’s simply not how it works. 😉

      I wish more of these outlets would use their power for EDUCATION. But, they won’t.

  47. One more stat from Meteorologist Payton Malone of WWL in New Orleans
    Here’s a wild stat. New Orleans has picked up more snow than Philadelphia this year, while Philadelphia along with many other major cities along the East Coast have been hotter than New Orleans. Yikes!

    1. Back to back patterns featuring specific types of blocking can result in such things. It’s easy to find the extreme contrast if you look. All that does is prove that weather is non linear. 🙂

      Just adding the proper perspective that media leaves out for the sake of impact. 🙂

  48. As you mentioned the other day no mention about the cool conditions out west.

    1. Mainstream media is very into cherry picking, more than ever. It’s far too obvious to this seasoned professional. I’ve been around a while. I know all the games. 😉

  49. I was out this afternoon. It felt like BERMUDA and the sky looked just like it as well. Temp was 85-87. Wind appeared to be SE to SSE and pretty decent.

  50. Still loving next week’s weather pattern for summertime activities!

  51. 81F, DP 63F in marshfield

    Out and about on what is a rather comfortable warm summer evening.

  52. DP front just north of Lebanon NH headed southbound. Dps in the mid 60s fall to the mid 50s behind it.
