DAYS 1-5 (JULY 25-29)

The biggest forecast focus in the short term is today’s heat and thunderstorm threat. The set-up is the classic high pressure offshore / cold front approaching and moving in from the northwest. No records are likely to fall in the heat department today but it’ll be pretty hot nonetheless, with high humidity, but not unlimited sun as already high and mid level clouds associated with the upper trough driving the frontal system into our region are already moving in as I write this. So expect some sun limitation from those. What we really need to watch for are developing cumulus / cumulonimbus clouds which will be a sign of the thunderstorms. Initially, I think a few isolated storms will pop in southern NH and perhaps north central MA, with eventually these increasing in number while the area moves southeastward, eventually forming a broken to solid line as it moves through the I-95 / I-90 belt and southeastward from there. The area with the best chance for the greatest coverage is southeast of the I-95 / I-90 region. Regardless, any storm can be strong to severe, so keep a close eye on the sky / radar especially if you have outdoor plans. I’m eyeing the possibility of a few more showers and storms, maybe even a small line, that can develop later in the afternoon and impact parts of southeastern NH and northeastern MA, which has been indicated by some reliable short range guidance. By tonight, the front sweeps through and the threat ends. High pressure builds in for Saturday which will be quite a nice day, but you’ll already notice some high clouds streaming across the sky during the day ahead of the next disturbance, which is set to bring more cloudiness back along with the chance for showers and thunderstorms at some point Sunday. Guidance varies on the timing of the shower / storm threat from this, but I’m leaning toward a dry morning and afternoon / evening unsettled weather. I’ll tweak and detail this on my weekend blog posts. Early next week, fair weather returns along with some July heat to go along with it as there’s no real delivery of Canadian air behind Sunday’s system. Later Tuesday, the next disturbance / front may be close enough to trigger late-day showers and storms to the west.

TODAY: Partly sunny. Isolated to scattered showers and thunderstorms develop north and west of Boston 1:00 p.m. to 3:00 p.m. time window, increasing in coverage while moving through Metro Boston, central to southeastern MA, eastern CT, and RI mid through late afternoon. Additional showers / storms possible southeastern NH and northeastern MA late-day. Any thunderstorms can produce frequent lightning, small hail, and strong (potentially damaging) wind gusts. Highs 88-95 except cooler South Coast / Cape Cod. Dew point near 70. Wind SW 10-20 MPH, but can be variable, strong, and gusty near any storms.

TONIGHT: Clearing. Lows 66-73. Dew point falls below 65. Wind NW 5-15 MPH.

SATURDAY: Mostly sunny. Highs 78-85, coolest coast. Dew point near 60. Wind N to E up to 10 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 62-69. Dew point near 60. Wind SE under 10 MPH.

SUNDAY: Sun followed by clouds with a chance of afternoon showers, possibly a thunderstorm. Highs 78-85, coolest coast. Dew point in 60s. Wind SE to S 5-15 MPH.

SUNDAY NIGHT: Mostly cloudy with a chance of showers in the evening. Clearing overnight. Patchy fog. Lows 61-68. Dew point falls to near 60. Wind W up to 10 MPH.

MONDAY: Mostly sunny. Highs 84-91, but turning cooler in some coastal areas. Dew point 60+. Wind NW up to 10 MPH except developing coastal sea breezes.

MONDAY NIGHT: Partly cloudy. Lows 63-70. Dew point 60+. Wind S up to 10 MPH.

TUESDAY: Partly sunny. Late-day showers / thunderstorms possible, mainly western areas. Highs 85-92. Dew point in 60s. Wind SW 5-15 MPH.

DAYS 6-10 (JULY 30 – AUGUST 3)

Overall pattern is dry with a slight cooling trend with dominant northwesterly flow from Canada. Disturbance bringing shower threat is most likely to pass by sometime July 31.

DAYS 11-15 (AUGUST 4-8)

Overall pattern features near to below normal temperatures but also mostly dry weather with a continued dominant northwesterly air flow.

  6. With the latest update SPC has more of SNE in a level two out of five risk for severe weather today with strong wind gusts the main threat.

    1. New update around 9AM

      I am beginning to really feel the humidity.
      I may have to move to AC soon. 🙂

  7. Logan 79, dp 70

    Here we’re at: 80, 70

    Way ahead of yesterday’s temperature rise.

  10. I always look at those overnight lows in the summer months. When those lows are in the mid 60s or higher it is going to be a sticky day. When the lows are in the 50s to low 60s a comfortable day is ahead.

    1. SPC discussion for our area

      …Northeast States…
      Morning water vapor imagery shows a fast-moving shortwave trough
      progressing eastward across Ontario. The associated cold front will
      move through the St Lawrence Valley this morning and southward
      across New England this afternoon. Relatively hot/humid conditions
      ahead of the front will lead to widely scattered afternoon
      thunderstorms across southern New England and eastern NY/PA. These
      storms will track southeastward toward the coast through the early
      evening. Coverage of intense storms is uncertain, but conditions
      will be favorable for gusty/damaging winds in the cells that form.

    1. Well done.

      I didn’t get it. So far, 37% have not solved it, which is very high.

      I’m not convinced that’s really a word. 🙂

    2. 4 for me too. I’ve looked it up three times and am still not convinced. SClarke, out of four I share with on FB, three have failed. The fourth hasn’t posted yet.

      I got very lucky with my first three guesses so that eliminated most of the many other choices.

        1. Love these stats!!
          I had the last 3 letters in order after 3 guesses. No word was making sense to me, so I just started plugging in letters when I plugged the correct 2 first letters, I said to myself is that even a word and then there it was, the solution!!!
          I was pronouncing it incorrectly so it made no sense to me. Didn’t even see what it really was until I looked it up.
          Even looking it up, I was not convinced that it was a real word.

          Most interesting little mind game!!!

  16. 86/72 here. I guess that would suffice for sufficient thunderstorm fuel!

    Likely surpassing 90 today.

    I guess Logan officially made 90 yesterday. We did not here as we only made 88.

  20. Many more members of the Ensembles are showing the potential for an East Coast threat about a week into August. The wave responsible for it has not even moved off of Africa yet, so plenty of time to watch.

    Historically, this would be very early for a threat up here, but not unreasonably so. Of the 18 hurricanes that made landfall in New England or Long Island since 1851, 15 of them have done so between August 19 and September 27. The earliest one to ever make landfall up this way was Hurricane Belle, which slammed into Long Island as a minimal hurricane with 75 mph winds on August 9, 1976.

    2. Great information. Thanks. I was wondering yesterday about timing for up this way. Gloria was late sept?? The 28th?? That’s a guess

  28. 88-95 range is nailed.

    Storm development a tiny bit early otherwise no surprises.

  29. Severe Thunderstorm Watch up. Radar seems to be jumping in Central and Western part of the region. Heading towards you, Vicki?

    2. Yes sir. Heading this way. We will see if it falls Apart. A friend in Sutton Center was hearing thunder

    1. Some impressive towering clouds Tomy south. Although storms are coming from the NW. I love skies like these

  33. Speaking of a seven-second delay, I am so happy, TK, to read that Mom seems to be improving! Prayers continue!

    Also, congratulations to you, WxWeather, your beloved and your families on your upcoming wedding. I think I remember reading it’s this weekend. I am not sure.

    My best wishes for a wonderful day and a beautiful life together! 🙂

    Wanted to get that out there before the weather started jumping here.

    And now for something completely different…

  37. Thanks, TK.

    We’re getting some wind and rain here in Sudbury with some loud crashes of thunder. Skies aren’t that dark to the west – seems like a fast moving storm. We’ll see.

  40. Just got a severe thunderstorm warning, BUT imho, it is going North of me09()@*!(#)&)(!@*&#()!*@)#(&!)@(#*)(!@*#)(*!@)(#$*!)(@*#$)(!*@#)(*!)(*()*

  42. We are now on the northwest side of Cape Breton in a coastal town/village called Chéticamp. French spoken much more frequently here.

    Weatherwise, in one of the windiest places I have been often, the wind is calm and with dps in the mid-high 60s and temps in the low 80s, it feels rather hot by Cape Breton’s standards.

    Cold front tonight with winds tomorrow off the Northumberland Straight. Should feel more like Chéticamp.

  43. We’re in a warned area now with very dark clouds to the northwest. A couple of claps of thunder.

  44. Watching an impressive line of clouds approach us in Padanaram Village – big thunderheads behind them. Sun still out with a fresh seabreeze – will the ocean shield deflate storms again?

  46. All’s clear here in Quincy. It got dark briefly but that’s about all. Little if any drops fell from what I can see. I do believe that Boston/Logan got slammed based on the radar from my very untrained eye.

    Any confirmation on Boston itself?

  47. Some thunder in pembroke , minimal lightning & just a drizzle . Nothing impressive at all as of now

  49. @JPDave – looks like that solid line deveining around Providence Fall River and Taunton as TK predicted – heavier east of I95

  51. Might be a wrap here as looks like sun coming back out , not even a puddle

  52. RRFS / HRRR were good today, but not “perfect”.

    HRRR had better timing. RRFS had better placement of cells / line. A cross between the two gave you your best convection forecast. Still, miles ahead of where we were forecasting thunderstorms with computer guidance just 5 and 10 years ago.

  53. Logan made 95,
    Taunton made 95
    Plymouth made 97

    We here in JP with tons of trees around only made 92.

    1. Trees make a big difference as noted through the years. Open sunshine and adjacent asphalt does as well. 😉

      No record at Logan!

  55. I double checked and, yup, we hit 98. The sensor to my trusty Oregon Scientific is in a solar radiation shield and that thermometer has been very accurate throughout the years.

    I can see and hear the storms down Swansea way.

  56. I was so jealous when I saw Vicki’s lightning tracker post on FB earlier (and then she deflated my elatement for her by saying the storms missed her entirely). I don’t think we’re going to get a single drop of rain, nor any thunder here in the Lowell/Nashua area. I’m so disappointed. My garden seriously needs rain, and I need a good storm to watch (the toddler would disagree, and prefers to hide under the dining room table with my iPad during a storm.)

    1. Sweet. We do have a tiny little lone something that looks to be making a beeline for me.

  58. Thanks, TK.

    We got an enthusiastic little blip of rain from the thing that took a ride down Route 2. Entertaining, though not productive!

  59. Front just came through here – quite impressive on the wind. Dark clouds about but no rain here – a few pop-ups around. The big stuff was definitely with the pre-frontal trough, as is often the case.

  60. I pulled out all the stops and grilled our dinner, but still nothing but interesting clouds.

  61. Lots of below normal temps upcoming for the Plains, Midwest, and Northeast starting middle of next week through about day 14.

    Meanwhile, mainstream media still hyping unrelenting heat for the same areas. Very out of touch with reality. #FollowTheScript … It’s summer, we gotta hype heat!
    How about this idea: Report realistically. What a concept!

    1. Speaking of 14, that’s the number of 90 degree days for Boston so far to date.

      Hope this doesn’t occur but is there 14 more in Boston’s future? Eric predicts 20+ before summer ends.

      1. Probably not. The # has always been wildly variable.

        I mean, look up the stats for 1983, and then look up last year. The last 2 summers have been below normal.

        Sometimes you have a summer that presents several patterns where the temp will bust 90 more often, and sometimes you have a summer where it struggles to ever get there. It’s just the nature of where Boston is.

        There is absolutely no definitive trend in 90+ days for Boston.

  62. For those who watch Jeopardy, a major upset tonight on the season finale! Wow! 😉

    See you in September Ken! 🙂

    Vicki, aren’t you a regular watcher?

    1. Yep. Hopefully everyone has seen the show. I’ll miss seeing new shows till sept.

    2. I just remembered. The now “former” Jeopardy champ streak ended at…14 days.

  65. Thanks TK.

    Lovely out now as the DP have dropped. Dog is killing me with the early mornings. Start work August 4th so hoping she’s sleeping in by then lol

    1. My dog is 13 and started with the early mornings about a year ago. It’s been killing me too. Nice to be up early but not when you go to bed late. Congratulations on your new job!

    2. Indeed, congratulations on the new job. I wish you all the success in the world!!
