Saturday Forecast

120 Comments

7:56AM

DAYS 1-5 (JULY 6-10)
Typical summertime pattern for New England. Heat and humidity today, add an approaching cold front and create a threat of thunderstorms, some of which could be strong. Will be monitoring radar through the day. Threat diminishes northwest to southeast as the front passes this evening. The front will still be close enough for early clouds and a South Coast shower threat Sunday but the trend will be to clear as we will then have an air mass much cooler and drier than the one we’re in now. High pressure brings great summer weather Monday to Wednesday, starting out pleasantly warm and dry then turning a little hotter but only slightly more humid toward midweek.
Forecast details…
TODAY: Partly sunny. Isolated to scattered thunderstorms after 3PM west and north of Boston, mostly after 5PM to the south. Humid. Highs 81-88 Cape Cod and immediate South Coast, 88-95 elsewhere. Wind SW 5-15 MPH, higher gusts.
TONIGHT: Variably cloudy. Scattered to numerous showers and thunderstorms with the threat diminishing from northwest to southeast. Any storms may be strong. Patchy fog overnight. Humid. Lows 66-73. Wind variable 5-15 MPH, higher gusts near storms, shifting to N.
SUNDAY: Mostly cloudy to partly sunny morning with a risk of a shower South Coast. Clearing midday-afternoon. Less humid. Highs 75-82. Wind N to NE 5-15 MPH with higher gusts.

DAYS 6-10 (JULY 11-15)
Overall west to east jet stream pattern. More humid with a risk of mainly afternoon showers/thunderstorms July 11 with an approaching cold front.

  2. 6:30 pm Phish snow at Fenway tonight….hoping thunderstorms have passed by then…I’m on the field so no cover…last night the shade covered my portion of the field right before showtime…was perfect.

      1. My oldest has a July birthday and says the same thing. Maybe it’s a July kind of thing.

  5. Barry has a 91 for Logan today.

    Amazing no talk of persistent heat so far. If this is going to be the general theme of this summer, I’ll take it! It could be so much worse, like last summer was, for instance.

    I would be curious if many buildings in Alaska have A/C. I wouldn’t want to sit inside a movie theater for 2+ hours up there right now. From what I understand, they are lucky to get to the 60s during the summer.

    1. Actually 70s and lower 80s are fairly common there in the summer. So that statement is quite inaccurate.

      1. As usual the National media (radio, tv etc.) continues to misinform the public. Thanks TK!

        Also global warming was mentioned as a factor as well.

        1. I wish sources were posted when the media is blamed. I have not heard anything like that. But I absolutely do not think warming can be ruled out. We are setting high temp records worldwide on a yearly basis.

          A person can say this or that caused one specific areas record. It is difficult to use that same reasoning for worldwide records. 2018 was 4th hottest in record. And

          “The average global temperature during 2018 was 1.42 degrees F above the 20th-century average. This marks the 42nd consecutive year (since 1977) with an above-average global temperature. Nine of the 10 warmest years have occurred since 2005, with the last five years comprising the five hottest.Feb 6, 2019” NOAA

  7. I see Barry tweeted this morning he’s predicting another (15) 90F days at Logan going forward.

    With it being July 6th already, that’s quite a bit more in the remaining time left in the summer season. (60 days to sept 4), (78 days to sept 22)

  8. Thanks, TK…

    Happy, Happy, SSK!

    Thinking about Mrs. OS this morning. Hope she’s okay.

  9. Matt mentioned a tropical cyclone in the Gulf next weekend. The latest ECMWF has it back again after going poof. I believe the model has it into Gulfport and Biloxi next Saturday, but I defer to our experts!!! 🙂

  12. Thanks TK!

    I’d expect fairly widespread showers and storms this afternoon. A few strong to severe with a damaging wind threat, but mostly “garden variety”. Somewhat of a flash flood threat also, but SNE has been pretty dry lately so it’ll mainly just be urban/poor drainage areas to watch. Sure is a humid air mass though. Really good stretch of weather coming behind the front, still warm but a lot drier.

    1. We will see regarding my basement. Last rain event quite a bit of water came in but fortunately away from my oil burner.

  16. My Acurite equipement sitting in the sun reads:

    93 with dp 81

    My dew point sensor seems to be on the fritz. DP is high, but not that high.

    2. I read 94 in sun with 75 DP. Other nearby stations except one at 101 are in high 80s. The DP does seem to be correct.

      I don’t know if it bothers you as much as it does me, OS; but I detest when it isn’t accurate.

  17. Lots of lines west of us as JPD said. I’m hoping for a good storm; but having gone through it last week, hope it doesn’t interfere with celebrations. Not everyone is lucky enough to have TK.

  18. Happy Birthday, SSK. If I could be you and handle (and like) the heat and humidity, I would be a happy person. Unfortunately, that’s not the case. I’m wilting and feeling quite ill. This has been a rough week. I’ll head to a local Starbucks soon for some AC.

    BB mentioned the possibility of 15 more 90 plus days. Goodness. I don’t know. Maybe moving to Nunavut is a possibility. Land and homes are cheap. I work from home anyway, and could simply work from home there. The diet is probably better than what I’m having here. I’d miss Boston and the trees, certainly. But, I would not miss the heat at all.

    1. I feel bad for the folks who dislike the heat & get ill from it . For me growing up in Marshfield on the beach it’s just my makeup .

      1. That’s a good thing, SSK. You’re a strong person.

        I’m a wimp in the hot and humid air. I admit it.

      2. I feel badly for anyone that the weather makes ill.

        I spent most of my time in the mountains and snow growing up. Maybe that’s why I like cold. But then I don’t mind this either. It’s actually not bad. We have an active breeze

    2. Not liking the possibility of 15 more days of this. I can probably handle 1-2 days at a time but not strung out of several days in a row.

      1. It is usually the BIG one first then smaller thereafter. Our planet makes no sense anymore.

  20. The dewpoint is high. I would pay the weather gods lots of money for a dewpoint in the 40s tonight. My willingness to pay point is really, really high. Unfortunately, such a dewpoint ain’t going to happen. I know.

  21. Out and about. car thermometer reada g 94.
    pretty damn hot and the humidity, well it sucks.

    I’m ok. Wife is pretty miserable. we are thankful for the acs. new ultra quiets are truly a gogsend. they are awesome and very quiet.

  22. quite a bit of lightning with the approaching storms. we’ll see what haapens near the coast.

    1. Wish your wife well. Let her know that a member of the fellowship of the 3-H miserable (me) commiserates.

      1. Thank you Joshua. Pretty rough day for her. She is sitting at her computer right next to the AC.

  24. These storms could be pulsing. There was a severe thunderstorm warning for lower Fairfield in CT then it weakened below severe criteria before the time it was suppose to expire. A good amount of instability but the wind shear is very weak for a bigger severe weather event.

    1. I think you may be correct.
      Nice write in the NWS technical discussion. PLENTY of instability and lifted index is juicy, but just not enough shear for a severe event.

  25. Man, is it digusting out there!! Just came in. Car was reading 95
    Accurite is reading 98 with dp 81
    Yes, I know the dp is wrong, but I am sure it is 72 or 73, disgusting enough!!
    The house is like a sauna. It is 87 in my office where the computer is.

    The temps in the room where the acs are running is 76. They are fighting hard, but tough
    to maintain temperature when it is this hot and humid. Plus rooms may be a tad too big for the 6150 btu units we have.

  26. Thank you Joshua. Pretty rough day for her. She is sitting at her computer right next to the AC.

  29. JJ thank you for the pulsing comment. I do not completely understand how that works. I will have to read.

    I do see the warning box in northern MA has expanded.

    1. I am getting notifications of lightning 15 miles from me but then that can mean something or nothing

  30. With pulsing thunderstorms there is nothing there and all of a sudden the thunderstorm strengthens and could reach severe criteria. As quickly as it does that the thunderstorm weakens and can’t sustain the intensity for a long period of time.

    1. Thank you JJ. And you are right. What appeared to be weakening is now warned. I see towering clouds to my NW

  31. AccuWeather Trivia Quiz

    The lowest temperature ever recorded on Earth was during the month of …
    A. January
    B. April
    C, July
    D. October

    Answer later tonight.

  33. Wind is picking up. Hadi, I had to look up Oakham.

    Lightning strike one mile of here. But storm further away. Shows how far lightning can be out from the storm??

  34. I hear thunder. 1st rumbles and I am sitting by an open window waiting to shut.

    btw. accurite has dropped to 87 from 98 with some down draft winds that felt really nice. 🙂

  43. I heard thunder but dead quiet now. But i hear wind and thunder in other parts of Sutton and I am south.

  46. Flash Flood Warning where the severe thunderstorm warning was. The atmosphere loaded with moisture today and not a surprise were seeing a flash flooding warning posted for the Worcester area. I got drenched walking to my car when I finished golfing earlier and very much like Florida in the summer when you get a downpour it does not cool down.

  47. You can thank those high dew points in the 70s for those downpours. I was surprised to see out of the Mt. Holly, NJ office which covers southern Jersey and eastern parts of PA they have issued so far two tornado warnings. I was not expecting that today.

  50. Vicki I got sunshine out right now. Will see what happens. I did experience a downpour earlier. Currently these thunderstorms here a producing very heavy rain and nothing reach severe criteria at the moment.

    1. Seems to be same for here. Although we just had ONE vivid flash and immediate loud clap of thunder.

  51. TK what is outflow dominant? And we have suddenly had two major lightning bolts and house shaking thunder. From out of the blue…or light grey

  52. There have been plenty of days in just over the past two months including today where we have seen numerous severe weather warnings in NJ and PA. It has been a busy severe weather season in these places.

  53. Here in SNE during May and June we were on the cooler stable side of the fronts where areas to our south were in that moist unstable air which thunderstorms love.

      1. Still raining here, though not cats and dogs, more like mice and bunnies.

        Today was an oppressive 95F due to the high dewpoint.

  57. On flight on our way back from Miami. Cruise was great this past week…we had three days at sea in the Caribbean as well as stops in St Martin, Puerto Rico, and Labadee Haiti and it did not rain once. Only days we saw rain were in Miami leaving last Saturday and again today upon our return. It seems the showers and storms in Florida are quite widespread this time of year so it surprised me how good the weather was once we got out over the Caribbean.

    Ironically with all the clouds and showers in Miami today, the high temp and heat index were about 5-7 degrees cooler than Hartford and Boston.

      1. But I bet the dewpoint temps were 5-7 degrees HIGHER than Hartford and Boston. Not much of a trade-off imo. 😉

  58. Answer to the AccuWeather Trivia Quiz

    The lowest temperature ever recorded on Earth was during the month of …
    A. January
    B. April
    C, July
    D. October

    The correct answer is C. This occurred in the early 1980’s in Antarctica. I think i was either 119 or 129 below zero.

  59. I had to laugh when I said “South Coast shower threat” for 3 or 4 days running regarding this morning and there is one isolated shower on the coast near the CT/RI border as of 7AM. Well I guess that verified. 😉
