DAYS 1-5 (JUNE 5-9)

Today we will have our first taste of the heat / humidity combo as much of the region away from the South Coast makes a run at 90 with dew point readings in the 60s – not oppressive and high end heat, but early in the season these conditions are more impactful than mid summer due to high sun angle and the “not-used-to-it” effect for many people. So if you are outside today, protect yourself from direct sun when possible and stay hydrated! Lingering smoke from Canadian wildfires will add to the hazy look of the day. I’m looking for dry weather other than the small chance for isolated showers and thunderstorms mainly 2 regions: 1) North of I-90 / west of I-95 due to a little help from lifting of air over hilly terrain. 2) South of I-90 close to a sea breeze boundary separating marine air from the hotter air mass over land. While the chance is very low in any one spot, any location that does get one could experience a brief very heavy downpour. Any of this activity will diminish and dissipate this evening and a fair, warm, humid night is on tap. Clouds become more dominant heading into Friday with more substantial moisture heading into the region, and this will likely lead to the development of showers and thunderstorms in what I expect to be up to a couple clusters – the first that may form in the morning to midday, the second sometime in the afternoon to very early evening. Activity Friday will favor areas near and west of I-95, and near to north of I-90 in MA, as well as into southern NH later in the day into evening, based on current expectations. These storms’ main impact will be heavy rain with local flooding, but I cannot rule out a severe storm with isolated wind damage. This activity lifts to the north for a quiet evening on Friday, but as a cold front comes into and slowly across the region Saturday, an additional opportunity for showers exists. I think the thunderstorm threat Saturday is limited to eliminated due to a more stable atmosphere overall. Part of this will be due to a small wave of low pressure passing by just to our southeast, putting a southeasterly air flow over much of the region, injecting a more stable layer of marine air, and more abundant cloud cover also making solar heating more limited. The timing of the showers Saturday is still TBD, but I do think there will be many rain-free hours in any given location. Sunday’s weather looks quite nice as the front pulls offshore and a drier air mass arrives. This will persist into Monday as high pressure builds across the region, promoting fair weather.

TODAY: Hazy sun much of the day, eventually some clouds pop up later. Isolated showers and thunderstorms possible mid afternoon to sunset. Highs 85-92 except 77-84 most of South Coast and 70-77 Cape Cod. Dew point 60+. Wind SW 5-15 MPH.

TONIGHT: Variably cloudy. Patchy fog. Lows 60-67. Dew point 60+. Wind SW to variable up to 10 MPH.

FRIDAY: Variably cloudy. Chance of showers and thunderstorms, favoring areas near to north of I-90 and near to west of I-95 midday to late afternoon. Highs 78-85 except 70-77 South Coast. Dew point 60+. Wind SW to variable 5-15 MPH.

FRIDAY NIGHT: Variably cloudy. Areas of fog. Lows 62-69. Dew point 60+. Wind variable to SW up to 10 MPH.

SATURDAY: Mostly cloudy. A few episodes of showers. Highs 68-75 coast, 75-82 inland. Wind variable, mainly SE to S up to 10 MPH.

SATURDAY NIGHT: Variably cloudy with a chance of showers and thunderstorms early, then partly cloudy. Lows 55-62. Wind shifting to NW 5-15 MPH.

SUNDAY: Sun/cloud mix. Highs 72-79. Wind NW 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 53-60. Wind NW up to 10 MPH.

MONDAY: Mostly sunny. Highs 72-79 except cooler coast. Wind N up to 10 MPH with coastal sea breezes.

DAYS 6-10 (JUNE 10-14)

Next trough and frontal system brings unsettled weather June 10 into June 11 then fair weather returns with high pressure returning. Temperatures variable, no extremes.

DAYS 11-15 (JUNE 15-19)

Indications are for fair weather early period / unsettled later period. No major temperature extremes indicated.

    1. The evening before it was the opposite. Looked like a deck of clouds approaching, but it was a deck of smoke.

      1. Yes !!

        I’ve been taking rides the last few evenings starting around 7:30 pm. Parked near the seawall in Marshfield and watched the sun set. Exactly as you described.

  2. Good morning and thank you TK.

    Made 84 here yesterday and last night’s overnight low was 62.
    Currently 71 with dp 61. Getting YUUUUCKY

    Latest HRRR still hints at a feable sea breeze along the immediate coast, “possibly” limiting Logan to highs in the upper 80s. We shall see. Tom mentioned this last evening.

    I am thinking 90 or 91 here at my location. We’ll know later today.

  3. Logan is up to 77 with West wind at 8 mph. Will that be enough to hold off a sea breeze? I doubt it, Unless that West to Southwest wind picks up.

    77 here with DP 64. Getting YUCKIER by the second!!!!

  6. Logan 81, dp 63 Wind West at 6 mph. Pretty light. Is a sea breeze looming????

    Here: 80, dp 65

    Yuckier still

    1. I don’t know what the exact numbers are for that area, but sounds about right to me.

      1. Logan 84, dp 63 WNW wind at 9 mph. That has increased, so If Logan does NOT go to a sea breeze, then they’ll make 90, else NOPE.

    1. The NAM constantly, in my opinion, overshoots dps.

      They have 71F dps in this area, which seems higher than every other model which has mid 60s and that alone can jack up the parameters. But, I still thought it was interesting to post.

  25. Captain F, thanks for posting more from the 1981 Stones concert. That was indeed the one in VA. It was a fabulous tour. I was living in Europe at the time and had tickets to see the Stones in 1982 in Rotterdam with a Dutch music journalist who had just interviewed Mick Jagger. Alas, I broke my foot playing soccer 2 days before the concert. Couldn’t go to the concert and ended my chances of becoming the next Lionel Messi before there even was a Messi. There was a Diego Maradonna, though.

    1. Glad you enjoyed it. Hope it made you feel better.

      In my lifetime, I have been blessed to see Pelé, Maradona, Beckenbauer, Ronaldinho and Messi play. Lamine Yamal from FC Barcelona is my current favorite. I believe he just got his driver’s license and still wears braces on his teeth! What a young talent!

      I hope to see at least one WC game (out of 7) at Gillette next summer.

  26. 90 here with dp 64

    86 at the airport with dp 64 and ESE wind at 12

    TOM NAILED that one.

    1. All the credit goes to the HRRR last night on its 00z run. I just reported what it showed. 🙂 🙂 🙂

    1. Yes, with what the 12z models have, I think they had to.

      I see its for hail and wind.

  28. 91 here with dp 63.
    With that dew point, the fans are effective. Add 10 to the dp and the fans become useless. 🙂 🙂

    Elected not to install an AC for one day, even though I lugged one down from the attic. It’s tolerable.

  30. Ocean has responded to this light Easterly wind and the water temperature at Boston Buoy is up to 58.3.

    1. I am guilty of forgetting that its early June when it gets hot, like this.

      The ocean is still rather chilly, relatively speaking.

  31. …Portions of southern New England…

    A weak surface boundary will be draped across portions of New
    England into central OH Friday afternoon. Ahead of this boundary,
    rich low-level moisture (mid 60s to low 70s F) dewpoints will be
    focused in a corridor from eastern PA into MA/CT and southern
    VT/NH/ME. Strong heating within this corridor will result in a
    narrow corridor of moderate destabilization (MLCAPE greater than
    2000 J/kg). Steepened low-level lapse rates also will foster DCAPE
    near 1000 J/kg. Vertical shear will remain modest, around 20-25 kt
    effective shear magnitudes, but strong instability will support
    strong to severe storms capable of damaging gusts through the
    afternoon.

    Here is the SPC’s northeast discussion for tomorrow.

  34. A lot of guidance today is trending toward different ideas about the days ahead .. not sure yet if it’s garbage or there’s a lot of truth to it.

    Summary…
    -May have to expand rain coverage both Friday and Saturday.
    -May have to add shower / t-storm potential to Sunday’s forecast.
    -May have to add rain chance to Monday’s forecast.
    -May have to expand the Tuesday / Wednesday unsettled weather chance to something a little more widespread.
    -May have to reassess the medium range pattern into mid month to something that looks a little more like May.

    I’ve typed “May” so many times, it feels like May all over again.

    More later……….

  36. Bit of a jolt getting back to 90+ temps. Glad it looks to be a one day stand. I am another person who is become weary of hazy, hot and humid in my old age.0

    1. I love this … but that should come as ZERO surprise to anyone who reads this blog regularly. 🙂

  37. made 92 here a little while ago.
    dp 67. yuck.
    I had to install 1 AC. more when it is hotter, longer.

  38. Tidbits…

    Medium Range
    CPC hints at near to above normal temps and near to below normal precipitation over the next few weeks.

    Longer Range
    Euro guidance is warmish & wettish for summer.
    CANSIPS & CFS are warmish (not overly hot) but dry for summer.

    Again, guidance / forecasts … not guarantees, but these are the leanings based on the aforementioned tools.

    Beware of highly spun headlines for clicks that take a CPC 3-month forecast (June-August) which shows a “whatever precent” chance of above normal temps and turn it into things that say like “Relentless heatwaves, unprecedented temps, summer scorcher from one end to the other, etc., etc.” … Social media has become polluted with sensationalism & in many cases alarmist wording JUST to get clicks and shares. It’s so the wrong way to use the medium, and it’s really disappointing.

    Lost in all that bullshit somewhere are the real stories. This is one place you can get them. Good luck in your quest for others. Gotta know where to look – at least many here do. 🙂

  39. Judging from your comment above, TK, for expanding rain Saturday, dinner outside at 5:00 might not work? Son, DIL and grandson and I have dinner reservations in this area. They are for inside so far and I’m thinking we should leave it indoors.

    1. Remains to be seen. I’m not totally going for this – just looking over some information and sorting. The 5:00PM outside dinner may still very well work out.

      I’m watching to see if an offshore low “steals” some of the moisture from the front. We’ve seen that before. 🙂

  42. 00z HRRR projecting lows of 70-71F across most of the area tonight along with a possible shower or storm northwest of Boston.

  43. Tomorrow will be cooler on the thermometer, but it’s going to feel like deep, tropical summer with upper 60 dps, still warm temps, not much wind and a high sun angle.

    1. The immediate shoreline may be the exception, as the HRRR has it 70F at Logan on the runway 🙂

  45. 21z it has Logan at 62F and Gloucester or thereabouts at 58F vs steamy inland.

    Severe weather possible inland to the northwest.

    Lots of moving parts to watch tomorrow.

    2. Looks all north of here now. Earlier north CT and my area was in severe bubble. Has that changed??

    1. The effects of the understaffing of NWS offices continues. That has to be a severe thunderstorm that needs a warning.
