DAYS 1-5 (JUNE 9-13)

This is the final day of the early-season heat wave, and when we break it, the heat won’t be returning any time soon, as the cooling trend that takes place the next few days is a representation of the overall trend for a while. However, we focus in this section on the next 5 days, and it starts with one more hot and humid day today for most of the region, of course still somewhat cooler as it has been daily along the South Coast and over Cape Cod where the wind flow has been at least partially off cooler ocean water. Some lingering moisture at mid levels of the atmosphere, left over from yesterday’s convective activity around the Northeast, has been enough to drop some light rain on parts of the region overnight through the first couple hours of daylight. In fact, the sun shining low in the eastern sky through a break in the clouds resulted in a fairly rare morning rainbow visible in some areas, including here at the WHW headquarters in Woburn. I’ll share a link to a photo of it a bit later. Those very light showers will exit in short order, and we’ll be left with a sun/cloud mix as it heats up again. But this time, a real change is on the way, in the form of a fairly strong cold front coming down from the north northeast and sweeping across the region this afternoon and evening. Despite the significant change in air mass, there is not a great deal of support for widespread shower and thunderstorm activity with this front, so I’m just expecting isolated to scattered activity to pop up ahead of and along the front starting around midday in southern NH and progressing southward so that the activity exits via the South Coast early this evening. Behind this comes a lowering of temperature and dew point to much more comfortable levels for Thursday with a north to northeasterly air flow, and maybe even feeling a bit on the chilly side by Friday morning as the wind blows from the east. That will be the coolest day of the next 5, though Saturday will show very little recovery in temperature after a disturbance passes by with perhaps a morning shower then drying out but with a continued easterly air flow. The wind will turn more southerly on Sunday ahead of an approaching trough and disturbance from the west, so it will warm up a bit, and the humidity will come up a tad but not really to “noticeable” levels. That disturbance may have some bite to it so we’ll have to be on the watch for showers and potentially some heavier thunderstorms by Sunday afternoon and evening. But that is day 5 so there is plenty of time to study the details for that one… One more reminder: The sun will rise partially eclipsed just after 5:00 a.m. Thursday, peaking just after 5:30 a.m. with more than half of it moon-covered, and then the spectacle ends a bit after 6:00 a.m. I do expect the sky to be mostly clear for this across the region but there may be a few clouds. USE EYE PROTECTION if you plan to view this. Even a partially blocked sun low on the horizon can still damage your eyes if you look at it directly.

TODAY: Considerably cloudy with light showers exiting eastern areas early. Sun/cloud mix remainder of day – isolated to scattered showers and thunderstorms southern NH and northern MA midday through mid afternoon and southern MA as well as eastern CT & RI mid afternoon through early evening, with brief but heavy downpours possible in some. Highs 85-92, cooler South Coast / Cape Cod. Very humid – dew point near 70. Wind W 5-15 MPH, but can be variable and gusty near any showers/storms.

TONIGHT: Partly cloudy. Areas of ground fog especially in lower elevations. Lows 57-64. Lowering humidity – dew point falling through 60s into the 50s. Wind N up to 10 MPH.

THURSDAY: Sun and passing clouds. Highs 75-82, coolest eastern coastal areas through Cape Cod. Drier – dew point falling to the 40s. Wind NE 5-15 MPH.

THURSDAY NIGHT: Clear inland, coastal clouds possible. Lows 50-57. Dry – dew point middle 40s. Wind NE to E up to 10 MPH.

FRIDAY: Partly sunny. Highs 65-72, coolest coast. Dry – dew point upper 40s to lower 50s. Wind E 5-15 MPH.

FRIDAY NIGHT: Variably cloudy. Patches of fog forming interior lower elevations. Lows 52-59. Dew point lower 50s. Wind E under 10 MPH.

SATURDAY: Partly cloudy. Chance of a few showers early morning. Highs 67-74, coolest coast. Dew point lower 50s. Wind E 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Areas of fog especially lower elevations. Lows 52-59. Dew point lower 50s. Wind SE under 10 MPH.

SUNDAY: Partly sunny. Chance of showers and thunderstorms afternoon and evening. Highs 72-79. Wind S 5-15 MPH.

DAYS 6-10 (JUNE 14-18)

Upper level low pressure crosses the region early next week sending a couple disturbances through with a couple rounds of showers/t-storms possible, then the flow flattens to more westerly but still a weak trough in the region with mostly dry but seasonable to slightly below normal temperatures expected into late week. Approaching disturbance at the very end of the period may help up-tick the warmth and humidity by June 18.

DAYS 11-15 (JUNE 19-23)

As we transition from the end of spring to the start of summer (solstice late on June 20) the general pattern is expected to feature an overall west to east flow and still a tendency for a little troughing in the northeastern US. This pattern would produce temperatures not far from normal, maybe a touch below normal overall, and a weak disturbance or two providing a shower threat with overall dry weather.

  1. Thanks TK.

    And thanks for your response early this morning.

    I am liking the upcoming temps. Glad that they will be sticking around for awhile! 🙂

  2. Thank you, TK.

    Tom and SSK and maybe Dr Stupid since he is moving north, I see you have a new wandering neighbor named Boo Boo. I love that the authorities are not intervening at this point. Hopefully, Boo Boo will find Yogi further north

    2. He or she is a mover making its way through the south shore towns & has passed trough pembroke . Folks have managed to get a few pictures . I’m hearing he or she has caused no issues at all and folks were told to leave it alone & no one will be trying to capture this animal as he or she finds there way home hopefully. It’s a cool story , but I feel bad .

      1. Booboo was in cohasset yesterday and sure is a healthy looking bear. I feel badly also since he seems to be lost. But then he got there somehow

    1. What catches my eye is the surface analysis picture.

      Activity was dangerous that day on the warm front.

    2. Believe it or not, I still remember that day.
      Fortunately, I didn’t live anywhere near Worcester.

      1. I was almost four and do recall my mom saying a house on one side of the street was demolished and a rocking chair on a porch on the opposite side was not touched.

  7. Does anyone have memories of that Worcester tornado? Reading the description the tornado was on the ground for 84 minutes which is rare to have a tornado here in New England on the ground for that long.

    1. I was 6 years old and living in Norwood, MA.
      It was cloudy and cool there as we were just on the other
      side of the warm front.

      I was too young to know what was really going on.

    2. I’ve said before that Todd Gross held a luncheon for his weather watcher group not long before he was asked to leave whdh. The guest speaker has a book on the 1953 tornado and was working hard to have it reclassified. His PowerPoint was amazing. I cannot recall his name but he may be familiar to weather folks on this blog

  8. If this happened today with radar technology I am sure we would have seen a debris ball signature with this tornado. This tornado just reading about sent debris flying for miles.

    1. I have a recollection of pieces of roof shingles falling from the sky in Norwood, about 30+ miles or so from Worcester.

  10. Bangor, ME : North wind at 13, dp down to 56F.

    Burlington, VT: North wind at 12, dp down to 60F.

    Its coming …….

    1. Indeed! Will it trigger any activity? I am thinking not much.
      I do NOT expect a drop at my house, but we shall see. 🙂

  12. There is always a chance something could fire at the last minute, but it looks like this will be a dry frontal passage. Too much
    like a Back Door Cold Front, which often comes through dry.

  14. Ran 6 miles this morning. Still warm, but not as brutal as Sunday. I can actually remember the last mile or 2 of my jog, and my bp isn’t crazy low. Maybe that’s just the amphibian in me, adjusting to the outside temperature.

  16. The 12z Euro projects Boston´s dp to drop from 73F at 8pm tonight to 53F at 2 am and to 50F at 8am tomorrow morning.

  17. 3 cells out there, one up around Wells, ME, another around Keene, NH and one NW of Springfield, MA

    They are moving SSE

  19. Looks like a refreshing night and early morning coming. I can open up the windows and let the air in.

    One heat wave down, and another ??? to go this season. We’ll see. Can’t do much about the weather. Just enjoy the seasonality and be grateful we don’t live in San Diego. I’m guessing they do not have a WHW equivalent in the San Diego area. If they do, it’s probably a VERY quiet blog.

    I can picture it now, the conversation that takes place on La Jolla Weather (LJW):

    La Jolla: Well, we might get down to 74F today (a degree or 2 less than it’s been the past 6 weeks), and a few clouds might come in from the Pacific. Will share some pictures later today.

    Gas Light District: Felt a cool breeze blowing through last night – must have been at least 9mph. Got down to 61F last night. Had to grab a blanket. And today I think I see one of the clouds you’re referring to.

  20. dp 63 at Manchester NH. I think the front has just past that area.
    It’s only about 60 miles or so away. It’s coming!!

  21. Clouds to my south must be spreading out from the cell Tom mentioned that just moved into CT. They are spectacular

  23. First day of 2021 to watch for thunderstorms on Sunday??? Tweet from Ryan Hanrahan and TK any further thoughts from you on this one.
    Definitely an interesting looking severe weather threat on Sunday. Both the Euro and GFS show some instability and significant low level wind shear. We’ll be keeping an eye on things.

    1. Well I don’t agree that it’s the first day of 2021 to watch for thunderstorms since I’ve already chased a couple of times.

      However I do agree it is a day to keep an eye on. There is definitely some severe weather potential, but still a few days away so really can’t elaborate yet.

  24. Small cell just popped just North of Worcester.

    Vicki, perhaps you’ll be in line for this one. Keep an eye on it.

  25. There is a warned area over Hartford. Not Coventry and darned if I can recall where you are when at work, Mark.

      2. It sure did. It produced so little rain that I stayed on deck. No thunder and sun is blazing hot again. That got me to go indoors.

        1. It also has me laughing out loud because it fizzled again literally as it moved past me

  31. So we are at the end of a 5-day heatwave for Boston which was actually a 3-day heatwave since their high temperatures on Saturday and today we’re actually under 90 even though they were recorded on their thermometer as being 90 or higher.

      1. 87 or 88.
        The point is that thermometer is off by two or three degrees. Therefore the data is incorrect. That skews a lot of things. It’s just disappointing that where we are right now a problem like this is not relatively small and taken care of immediately. Money gets in the way of so many things that does not need to get in the way of and this is just one of them. But this particular one has a significant impact on climate data. If we want to track what happens with our climate we start with accurate data, not taking readings from things that are not giving us correct readings.

        The last time Boston had a 5-day heatwave this early in the season was 1925. “On paper” that was just equal today. In reality, The last time Boston had a 5-day heatwave this early in the season is still 1925.

          1. Not at Logan. It was at one of several locations in the city pre-1936.

            That still doesn’t change the fact that the thermometer is off by 2 or 3 degrees now though.

              1. They are better. Still need to be checked for calibration but you’d find they don’t suddenly go off like this “high tech” stuff does.

  32. Thanks TK.

    Vicki, I work in Manchester, CT. We got a direct hit from that warned storm earlier but really didn’t have much more than a heavy downpour and some thunder. Not much in the way of wind and definitely not severe.

    Back home we somehow managed to pick up virtually nothing in the rain gauge between yesterday and today. At one point yesterday it looked like a wall of rain was moving at us from the west and it just fizzled as it moved east.

    1. Thank you, Mark. Crazy that you didn’t get much in Coventry.

      Mac and his brother had two ping pong tables of Marklin model trains. Well, Macs dad really has them 😉 He gave to my son and the only place we could find Marklin trains was in Manchester. So we traveled there fairly often.

  33. Disappointed in the Bruins. They just didn’t show up tonight. I did not expect that. Tip of the cap to the Islanders. A better team, better coached, and more mentally prepared for this series.

    1. Islanders played with a lot of heart. They have no real superstars, just four solid lines top to bottom and they win by committee. Bruins are a bit more top heavy with the perfection line. The injuries on the Bruins defense and Rask clearly not playing at 100% were factors as well.

      Islanders will have their hands full again this year with TB. They are going to be heavy underdogs but hey, you never know.

      1. My goodness I hope they get by Tampa…..
        I’m now behind my 2nd favorite team 100%.

    2. Game started bad by starting Rask as he had no business In net tonight . I’m pretty confident they will go a different route next season in net as I honestly believe Rask is gone . He’s not the reason you lost but was a part of it .

  34. What an awesome and gutsy performance by the Islanders tonight and in this series as a whole. They wore down a very good team in the Bruins who have a lot of similarities to themselves. Cassidy will be hearing those “New York Saints” chants in his sleep tonight!

    1. I think TB is going to be a very tough series for you guys and would have been for Boston as well .
