DAYS 1-5 (MAY 31 – JUNE 4)

Today we wrap May up with a much less stormy day than we had yesterday, however we remain under upper level low pressure on the eastern side of an omega block configuration, and that leaves us vulnerable to additional unsettled weather. The next disturbance drops into this trough via eastern Canada later today and lingers into Monday, bringing us a couple additional rounds of showers, the first later this afternoon into this evening, and the second early Monday. We can still see pop-up showers from diurnal heating Monday and Tuesday afternoons, but those should be rather isolated. High pressure brings more sunshine without a shower chance Wednesday. By Thursday I still expect dry weather but we may see more cloudiness again from a combination of a disturbance to our north and west and another offshore to our south.

TODAY: Sun then quite a few clouds. Mid to late afternoon shower threat develops from north to south including a slight chance of thunderstorms. Highs 62-69. Wind NW 5-15 MPH.

TONIGHT: Variably cloudy with showers possible in the evening then partly cloudy overnight. Lows 50-57. Wind NW 5-15 MPH.

MONDAY: Partly sunny. Isolated showers. Highs 65-72. Wind NW 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Lows 50-57. Wind NW 5-15 MPH.

TUESDAY: Partly cloudy. An isolated shower possible. Highs 66-73. Wind W 5-15 MPH.

TUESDAY NIGHT: Clearing. Lows 50-57. Wind W up to 10 MPH.

WEDNESDAY: Mostly sunny. Highs 67-74. Wind W up to 10 MPH but coastal sea breezes possible.

WEDNESDAY NIGHT: Mostly clear. Lows 50-57. Wind variable up to 10 MPH.

THURSDAY: Partly sunny. Highs 65-72, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (JUNE 5-9)

The omega blocking pattern starts to weaken gradually including de-amplifying for a more northwest to southeast flow. Watching a cold front that can bring a shower and thunderstorm chance on June 6 and some lingering cloudiness as the front may be slow to depart on June 7. That’s about the only bump in the road I can see right now in an otherwise fairly benign pattern that lacks a lot of rain as well as any sustained warmth.

DAYS 11-15 (JUNE 10-14)

Borderline block to zonal .. transition toward more zonal continues as far as I can tell, but quick reversal to temporary blocking again is not completely out of the question. Overall looking at limited rain chances and somewhat variable temperatures not straying too far from seasonal “typicals”.

  1. Good morning and thank you TK,

    Up to 60 from low of 42

    Ocean: 51

    That storm brought the ocean temperature down with a combination of upwelling and Colder surface water being transported by the wind from the Gulf of Maine. At least that is what I think happened.

    Wordle: 3 Interesting word. I just tried it on guess 3 and it was the word.

    1. A water mixing is probably what drove the temp down a bit. Not straight upwelling but a “turbulence” as the temperature is pretty chilly not too far underneath the slightly warmer surface water.

  2. Thank you, TK. Up to 53 from a low of 36 with brilliant sunshine. Hoping the clouds will stay away tonight so we can see the blue micromoon and planet alignment

  3. Excellent 3 JPD. After guess 2, I had four letters with one in correct position. After trying a bunch of combinations, I did the same thing you did. And was surprised.

    Wordle 3

  4. Thanks TK !

    Wordle: 6 (a new word for me)

    We lost power for about 3 hrs yesterday, got it back just before headed to a graduation party for our youngest daughter’s long time friend.

      1. Yes, came on after about 3 hrs out, we were out from about 11am – 2pm. But, we were headed out the door right when it came back on. But, it was nice to leave knowing it was going to be on when we got back later on.

        1. Awesome. I remember a time I enjoyed outages. Not sure what happened to that Vicki

  6. Entering today, May 31st at Logan, 18 of the first 30 days of the month have had temperature departures (both ways) of 5F or more

    Of those 18, 5 have been 10F or more (both ways) and if those 5, three of them have been 15F or more (above avg).

    So, there’s not been a ton of close to average this month, it’s been either really, really warm, or to a slightly lesser extent, really, really cool. But the last 2 really, really cool days have occurred last Sunday and yesterday, Saturday. The timing is what it is.

    2. Looking again, the first 7-10 days of the month ran closest to avg, but it’s been the last 3 weeks that have had a bunch of anomolous warm/hot days and cool days with less centered around the average.

    3. Thanks Tom. This gives some support of the idea I posted as a reply to TK’s penultimate post on yesterday’s forecast:

      “I have a guess as to why people think this is an unusual spring. I don’t know this for a fact, but I have a feeling that the standard deviation of the temperature is greater than usual. It’s those outliers that get people’s attention.”

  9. Thing about spring…of the 4 seasons it’s the least likely to have a day where the temperature is close to average. In other words, as I frequently say, it’s the most volatile of the 4 seasons. It always has been. 🙂

    1. Makes sense.

      The cold source regions are plenty cold and easy to overwhelm the strong sun.

      Conversely, when you get a ridge and all the air is coming off the continental US, combine in that 60-70 degree sun angle and it can zoom to very warm or hot real fast.

        1. 45-55 in eastern areas was not a surprise to me. It was rather short-duration, which was expected too given the small size of the system and its area of tightest PG.

  11. Lots of turbulence coming up from Sarasota last night. Flight attendants had to buckle up for the last 30 minutes of the flight. ✈️ I had to turn on the heat to warm up my residence. Now back to reality. Have the best day everyone.

  12. I don’t buy the tweaked version of the RRFS depiction of Monday.

    Something is still amiss there.

    I think the version they left alone combined with the current version (somewhere half way between) is the best version so far.

  13. Considering such a vigorous storm yesterday, Logan received a very paltry 0.35 inch. It’s no wonder we’re still in a moderate drought.

    1. No surprise. As I mentioned a couple days ago, the core of the heavier precipitation was expected to stay to the north and also be rather narrow.

  16. First Wordle 2 in quite some time! Had the 2 and 5 after 1 and just kept all the options and eventually the answer was the only thing I came up with…

    1. Excellent!!

      I was wondering how it was going to work out with all today’s 3s running the train. You saved us – sobriety is no longer required for the 3s. 🙂

  18. The visible satellite loop is fascinating this morning. 🙂

    High cloud shield from NNW battling dry air initially.
    Mid level clouds with orograhic initiation to our NNW, slowly moving this way.

    All that’s left are the lower based cumuliform clouds to help perk some showers later as that next disturbance moves through the trough over the region.

  19. News today is that some of that meteor may have made it to the surface (Cape Cod Bay) and may be in about 100 feet of water out there. It’s not highly unusual for a rock of that size to partially survive to the surface when most of it has burned up prior to reaching the surface.

    We’ll see what comes of it, if anything.

  20. FYI: There’s a post going around social media, AI generated, that is misrepresenting what happened with yesterday’s meteor event.

    It shows the wrong track on the generated map, and it also has a couple different versions where AI-generated quotes mention that the sky was “clear” in the Boston area during the event (some mention specific towns). The sky was not clear in the Boston area. It was overcast with rain in the region at the time of the event in the Boston area.

    If you come across such posts, best to report them as false information to Facebook or whatever platform you see them on.

  22. For hockey fans, Stanley Cup Finals begin on Tuesday.
    Carolina Hurricanes vs. Vegas Golden Knights.
    Games 1, 2, 5 if necessary, and 7 if necessary are in Carolina.
    Games 3, 4, and 6 if necessary are in Vegas.
    All games start at 8 p.m. Eastern and are scheduled for June 2, 4, 6, 9, 11, 14, & 17.
    Prediction: Carolina in 6.

    For basketball fans, the NBA finals are the San Antonio Spurs vs. the NY Knicks.
    San Antonio hosts games 1 & 2, NY hosts games 3 & 4, and then they go back and forth with 5 through 7 if necessary. Same format as NHL’s best-of-7.
    The games are all 8:30 p.m Eastern and the schedule is June 3, 5, 8, 10, 13, 16, & 19.
    Prediction: Knicks in 6.

    As you can see, the schedules are set so that there are no NHL / NBA overlaps. This of course maximizes potential from commercials sold as they count on hardcore sports fans who want to see both not having to just choose one on any overlap night. Instead, they’ll tune in a maximum of up to 14 nights if both series should go the distance. 😉

    1. I root against any “New York” team involving a championship. It’s that “Boston vs. NY” rivalry that must be kept intact! 😉

      You’re probably right though, those Knicks seem destined, unfortunately.

      1. I’m not rooting for Texas. NY over them every time. 🙂

        The only exception might be Rangers vs. Yankees.

        The NY Jets don’t count. They’re from New Jersey and just don’t want to admit it. 😉

  25. The short range guidance trend today has been for a pretty potent spin to come through here tonight & first thing tomorrow. The showers and embedded t-storms in the area now are part of it.

    The trend has also been for fewer diurnal showers on Monday, but still a very slight chance, and a very slightly better chance of them on Tuesday while we still have a cool pool overhead.

  27. It’s getting dark here and I just heard thunder.

    Are we going to have a bunch of those “rainy” weekends again like last year?

    Raining now as well.

      1. We didn’t have 14 rainy weekends in a row. We had 14 weekends in a row in which rain fell at Boston for part of at least one day. In some cases, it was a matter of minutes. About 0.5% of a a 48 hour period with raindrops falling is most definitely NOT a rainy weekend. The media overly-dramatized and over-stretched the meaning on that to the point of it being completely ridiculous.

        Also keep in mind that on average, 1 out of 3 days will see at least some precipitation at any given location in our area.

        There is NOTHING special about Saturday and Sunday. Nature doesn’t “know” that we have days of the week and concentrate 2 of them as a “weekend”. We completely made that up and we like to look for things that ruin them, even though most things don’t ruin them. It’s a very odd side of human nature that many (not all) of us have, and media exploits the ever living crap out of it, much to my annoyance.

        I’m done with that rant, but my goodness did it feel nice to do that one. 🙂

  28. I have to say after an extended period down in Sarasota I’m actually feeling a bit chilly . The Sarasota area is great place to visit if one is into golf and going to the beach. ️. There are top notch restaurants and entertainment venues.
    Siesta Key Beach always rated in the top ten best beaches in the country.
    I will dare to go in the water Thursday if the weather cooperates.
    I’m hoping for sixty degree water temps so I can at least go in the water up to my knees. We do have some great beaches here on the Rhode Island south coast.
    Have a great week everyone.

    1. Limited view at first, better later. Maybe a shot at seeing it prior to sunrise as well, but I’m not too keen on completely clearing.

  30. Thanks TK! Regarding my rant last night – Here is the problem with this spring the way I am experiencing it. The timing of the bad weather. It seems to be falling on the times I am out of office and outside.

    For instance in addition to Today where I am shivering in the rain at a lacrosse game (currently halftime)here is a sample of my bad weather days the last several weeks:

    Golfing in rain and chilly breeze a few times.
    Left a fundraiser on a Saturday evening in early May as it was pouring – got soaked – drove home in rain.
    Two of my long runs in a chilly drizzle.
    Pre prom pictures – it rained (although it did recover later in evening
    Beginning of spring break – rainy and cool.

    It’s the timing. Many of my long days in the office have been brilliant spring days. This is why I believe many are saying it’s below normal or rainy because it happens when they are off.

    Thursday is graduation – it is trending to be a splendid day. I promise to celebrate if that is the case!

  31. May in Boston: Warm (+3F) and dry (significantly below normal precipitation).
