DAYS 1-5 (JUNE 7-11)

Seven days into June, but after the last few days you’d think it was late June or July, as we are in the midst of an early-season heatwave. But the end is in sight! So far, the humidity has been kept in check, with dew point temperatures staying several degrees below the oppressive threshold. That will continue today, however today will probably be the hottest day, temperature-wise, as we have the maximum amount of sunshine and the peak upper level ridging, with surface high pressure to the south pumping in the heat. There will be a weak surface trough sneaking into western portions of the WHW forecast area this afternoon and evening extending from a disturbance moving into the Great Lakes, and this may trigger a couple isolated showers or brief thunderstorms later today but that is a fairly remote chance. Tuesday, the heat may come down a couple notches on the thermometer in general, but you won’t notice it, because the dew point will climb a few, so it will essentially feel as hot and maybe even more uncomfortable to those sensitive to higher humidity. There will be an ever-so-slight shift of the upper ridge to the west while the surface high keeps sending in the heat and humidity. The surface trough will hang around extending from the disturbance lifting from the Great Lakes to the St. Lawrence Valley, while increased moisture arrives from the southwest, having traveled all the way from the southern Plains with a weak upper level disturbance cutting through the high pressure ridge. This subtle increase in moisture and lowering of temperatures aloft, combined with solar heating, will lead to a slightly better chance of showers and thunderstorms, which will be isolated to scattered across more of the region Tuesday afternoon and early evening. Again though, there will probably be many locations that are missed by this activity, so don’t count on one of these to water your garden for you because it may not happen. If it does, it won’t hang around too long and any activity will fade away with sunset, leaving us with a very warm and sticky night as dew points reach their maximum for this stretch of summer weather. The high humidity will continue into Wednesday ahead of an approaching cold front, which will be moving southward out of eastern Canada. As previously mentioned, the timing of this front is the primary determining factor in how hot we get Wednesday. While some increased cloud cover will help limit us from reaching the maximum potential temperature for the air mass, the frontal boundary will probably not make it into the region until late afternoon or evening at the earliest, so it will still be a very warm to hot and humid day. Showers and thunderstorms are most likely on this day of the next three for any given location. A few air mass showers and storms can pop up ahead of the front, but the front itself may help to organize a broken to possibly solid line of convective activity as it pushes through later in the day or at night. Will have to monitor closely that day for detailed timing and impact of activity, but not expecting any widespread severe weather due to lack of parameters for it. And then a big change comes! Behind the front, high pressure builds out of Canada for Thursday with a northeasterly air flow of cooler air with lower dew points, so it will feel much more comfortable. I’d love to tell you that we’re going to see two days like this, but Friday’s forecast is not that clear-cut. The front, after it comes through, is going to put its breaks on just south of New England and sit there, and a disturbance coming eastward from the Midwest may initiate a wave of low pressure on it. With high pressure to the north, and a low pressure wave moving eastward along a nearby front, I can’t rule out a period of rain at some point on Friday. This is not currently the scenario shown by all guidance, so there is some doubt, but for now I am going to lean toward this scenario, not quite like Memorial Day Weekend, but clouds, cool air, and some wet weather in the forecast, with the distinct possibility of having to tweak that outlook. Also of note, the sun will rise partially eclipsed on Thursday morning (June 10), so if the sky is clear enough we’ll be able to see that celestial spectacle. Updates to come…

TODAY: Sunny morning – any low clouds near South Coast dissipating. Sun/cloud mix afternoon/evening – slight chance of an isolated shower or brief thunderstorm southwestern NH, central MA, and northeastern CT. Highs 90-97 except cooler South Coast and Cape Cod. Moderate humidity – dew point middle 60s. Wind SW 5-15 MPH, a few gusts around 20 MPH.

TONIGHT: Variably cloudy evening. Mostly clear overnight except areas of low clouds and fog redeveloping near the South Coast. Lows 67-74. Higher humidity – dew point upper 60s. Wind SW up to 10 MPH.

TUESDAY: South Coast low clouds and fog diminishing during the morning, otherwise a sun/cloud mix. Isolated to scattered showers and thunderstorms possible mainly mid to afternoon to about sunset, with any of these possibly producing torrential downpours and quick localized street flooding. Highs 88-95 except cooler South Coast and Cape Cod. Very humid – dew point near 70. Wind SW 5-15 MPH, can be briefly variable and gusty around any showers/storms.

TUESDAY NIGHT: Partly cloudy. Areas of fog especially South Coast and interior lower elevations. Lows 68-75. Very humid – dew point near 70. Wind WSW under 10 MPH.

WEDNESDAY: Partly sunny. Chance of showers and thunderstorms in the afternoon and evening. Highs 85-92, cooler South Coast / Cape Cod. Very humid – dew point near 70. Wind WSW 5-15 MPH, a few higher gusts possible.

WEDNESDAY NIGHT: Mostly cloudy with a chance of showers/thunderstorms early, then clearing. Patches of ground fog forming. Lows 60-67. Lowering humidity – dew point falling through 60s. Wind shifting to N 5-15 MPH then diminishing.

THURSDAY: Sun and passing clouds. Highs 75-82, coolest eastern coastal areas through Cape Cod. Drier – dew point falling through 50s. Wind NE 5-15 MPH.

THURSDAY NIGHT: Clear inland, coastal clouds possible. Lows 51-58. Dry – dew point upper 40s. Wind NE to E up to 10 MPH.

FRIDAY: Clouding over. Chance of rain in the afternoon. Highs 65-72 but may turn cooler late-day. Wind E 5-15 MPH.

DAYS 6-10 (JUNE 12-16)

Another push of high pressure from eastern Canada should bring dry weather and cooler than normal temperatures for June 12 to start the weekend, followed by a warm-up June 13 to end the weekend, with the possibility of the arrival of some rain showers with a system from the west. Generally west-to-east flow expected to evolve thereafter with dry/mild weather June 14, a warm front bringing clouds and showers June 15, and a cold front bringing the risk of showers/thunderstorms June 16 based on current medium range timing, but of course tweaks and changes are possible to this early outlook for mid June.

DAYS 11-15 (JUNE 17-21)

Continuation of zonal flow pattern with variable temperatures not overly far from seasonal normals, and a couple chances for showers/t-storms with passing disturbances as we head toward the summer solstice (which occurs late at night on June 20).

  4. I´m trying to recall, having looked a bit ago, I think both the 00z NAM and EURO project Boston´s dp at 74F at one point Wednesday.

    I´ve been reading school communications about working to get through Monday and Tuesday. And I keep thinking, I know it might be 10F cooler Wednesday, but the humidity is going to be oppressive and Wednesday might be more uncomfortable than these hot days with relatively lower dewpoints.

    1. Are schools in your area releasing early? Sutton did not but I think the higher grades have AC. I have not seen any schools switch to remote but may well have missed them.

      1. No they aren´t, but our Superintendent is great and he´s been communicating with all the Principals to extend and increase mask breaks, to utilize parts of buildings that have A/C for breaks, etc.

        Marshfield High´s school is fine because its brand new and has central cooling.

        I still feel for any school that has the window units, because that means the school doesn´t have central cooling, thus the halls get hot and stuffy and of course, every time the door to your classroom opens and closes, invariable the heat from the hallway, from the sun pounding on usually old buildings and from all the people in the room for multiple hours, I have found, usually overwhelms a window unit by noon.

        1. Thanks, Tom. Awesome that the superintendent is hands on. I believe some of the schools have agreements with regard to temp. I wonder if this similar to Captains wet bulb reading for sports.

          1. Yes, there´s a room temp agreement over a period of time in Marshfield. If that is met, than the school´s leadership team is asked to find a cooler location for that classroom.

            Its just another challenge, in a year of incredible challenges, that students and staff have been presented with. I can´t remember a sustained warm period like this in recent Junes. I just feel for all, they didn´t need this particular challenge, this particular year.

  9. 9am dew-points running 66F to 68F in eastern sections, 64F to 66F in central and western Mass

  10. Aging myself here, too bad we don’t have the old Boston Garden for tonight’s hockey game …. fog anyone ? 🙂 🙂 🙂

    1. Ha Ha HA

      Loved those 3 or 4 foot long stalactites (of who knows what composition, mostly filthy dust) hanging from the
      ceiling. Most digustingly viewed from the 2nd balcony.

      1. Watched Bobby Orr’s first season from the 2nd balcony. We’d go day of game and get those tickets for $2.50. Those seats were way up there!!!!!

    2. Since I’m going to the game tonight, I much prefer the new building in this weather. I don’t feel like sweating all night long due to the weather (or the product on the ice).

      I went to a playoff game in St. Louis in 1998 against the Red Wings (Brett Hull’s last game as a St. Louis Blue). It was in the mid 90s that day, and walking to the Kiel Center from Union Station in a hockey jersey was brutal.

  11. With regarding the partial eclipse at sunrise on Thursday, does anyone here know how/where to purchase special glasses for safe viewing? I believe it won’t last all that long.

  12. Logan’s wind has gone to light South wind at 7 mph.
    Is a SEA BREEZE in the works? or just a temporary change?

    I see winds very light all over Eastern MA. Not much of a gradient.

    Today would be a GOOD day for a SEA BREEZE!!!!

      1. I did a lot of checking when I saw first one to be sure. But I could tell DP was climbing when I headed inside almost immediately from my coffee on the deck

  15. Logan 91
    Norwood 90
    Bedford 90
    Fitchburg 90

    My equipment is reading 91, but it is now in partial sun and entering the part of the day where it will read a little high.

    Probably 90 here.

  18. Ugh, Logan’s thermometer…

    They registered a high of 91 on Saturday and it was actually 89. So today we will have a heat wave there that is not actually a heat wave…yet.

    1. That is cool that it has lightening detector.
      Nice display.

      Davis Instruments are excellent, albeit more expensive.

      Best of luck.

      1. Thank you. I’ll call Davis first. I do like the lightning detector but I get warnings through radar scope or is it radar pro

  21. Maybe because I’m reading my email and watching the juggling act going on to change from hot rooms to cooler rooms …..

    Cancel tomorrow and Wednesday, bring the kids back Thursday and let them finish out into next week. With face masks, it’s too hot. The kids and staff have some miracle work this year and we’ll get them caught up in the years to come, but this is too much until it really cools off Thursday.

    Just my 2 cents.

    1. I agree. Uxbridge has an earth release tomorrow. Overall, I guarantee absolutely nothing is being accomplished. Even my remote kids are having trouble holding a WiFi connection

    1. So odd how snow and freezing temps do not keep me inside but HHH does. Once sun sets behind the trees on hill to my west, I’ll head on out. The evenings have been lovely…….so far

  24. 95 … NOT! haha what a joke.

    Dew points are running 60 to 65 across most of Eastern Mass, ignoring Marshfield’s very bogus reading. When you get to the South Coast it is a little more humid down there but temperatures are a little bit cooler.

  25. Today’s high temperatures are slightly underachieving across the region based on expectation. Dew points are generally right where they were expected to be.

  26. 92 with 69 DP ….DPs have been in mid to high 60s around these parts all day. Maybe anywhere west of metro west 🙂

  27. The visible SAT loop has been awesome today. The marine layer (visible by stratus) smashing into the land and islands has been awesome to watch.

  28. Thanks, TK!

    All sports at our high school were cancelled this afternoon. There is a night playoff softball game under the lights tonight.

    The regional track meet has been postponed to Thursday when it will be much nicer for a meet.

    Montreal looks to close out and sweep the Jets tonight to win the North Division crown. Les Canadien have won six straight games and Carey Price is hotter than our weather! 🙂

    The NHL and the Canadian government have reached an agreement for the home semi-final games in the Great White North.

    There is a slim chance that the Bruins and Canadiens could play for the Stanley Cup. The four division finalists will be reseeded based on their regular season points. Boston and Montreal, because they are currently in the same conference, haven’t played for the Cup in the finals since 1978!

    NHL playoff hockey is the best!

  29. Dave, how’s Mrs. OS doing?
    I always think of her in these tough days. Any issues with her second dose?

    The AC in our brand new building only half works. Guess what floor? The World Language Department! Our wonderful principal moved my class to the first floor where the AC does work. Very comfortable. The HVAC is working on it. They think it’s a malfunctioning compressor pump.

    1. I’m hearing that it is not unusual for the AC systems to struggle. I’m so sorry to hear this.

      Take care the next couple of days

  30. Hey hey hey. Not weather related but my buttons are really bursting. Sutton HS principal Ted McCarthy was named Massachusetts principal of the year. Last year was Mike Rubin HS principal from Uxbridge. I’ve watched both on school committee meetings for well over a year and they are amazing.

  31. Islanders of 2021 remind me of the Blues of 2019. I liked the Blues in 2019 (even though they beat the Bruins) and I like the Islanders (even though they’re beating the Bruins). No player jumps out at you. Yet, it has character. Less style and talent than the Bruins, but I think the Islanders are better thus far as a team. The series isn’t over, but it’s going to be very hard to win in the Coliseum.

    1. Believe me I want the Bruins to win this series, but since the Isles have been my #2 team for decades, if they take out the B’s I’m behind them to win the whole thing.
