DAYS 1-5 (AUGUST 15-19)

Canadian high pressure moves in today, delivering drier air and fair weather, then hangs around into the start of the weekend before drifting southeastward over the Atlantic waters by Sunday. An approaching warm front will bring patchy clouds Saturday, otherwise that will be a rain-free, comfortable day, before a spike of heat and humidity Sunday, along with a good chance of showers and thunderstorms from an approaching cold front. This will be followed by another Canadian high pressure area with cooler, dry weather early next week.

TODAY: Mostly sunny. Highs 75-82. Dew point 60+ South Coast, 50s elsewhere. Wind NW to N up to 10 MPH.

TONIGHT: Clear. Ground fog patches possible in low elevations areas. Lows 53-60, coolest interior valleys, mildest urban areas. Dew point lower to middle 50s. Wind calm.

SATURDAY: Partly sunny. Highs 80-87, coolest coast. Dew point sub-60. Wind variable up to 10 MPH with coastal sea breezes.

SATURDAY NIGHT: Partly cloudy. Patchy fog overnight Lows 62-69. Dew point rises slow over 60. Wind S up to 10 MPH.

SUNDAY: Partly sunny. Afternoon and evening showers and thunderstorms probable. Highs 85-92 except cooler South Coast. Dew point rises through 60s. Wind SW 5-15 MPH.

SUNDAY NIGHT: Clearing. Lows 57-64. Dew point falls to 50s. Wind N 5-15 MPH.

MONDAY: Sunny to partly cloudy. Highs 73-80. Dew point remains in 50s. Wind NE 5-15 MPH.

MONDAY NIGHT: Mostly clear. Low elevation fog patches. Lows 52-59. Dew point lower 50s. Wind variable under 10 MPH.

TUESDAY: Mostly sunny. Highs 72-79. Dew point in 50s. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (AUGUST 20-24)

A stretch of fair and pleasant weather follows mid to late next week, during which time surf and swells along the coast will increase as Erin passes by between Bermuda and the US East Coast as a formidable hurricane. The August 23-24 weekend presents higher humidity and eventually a shower and thunderstorm chance – details TBD.

DAYS 11-15 (AUGUST 25-29)

Pattern indications are for a more northwesterly air flow in the region. Some up and down temps, but trend for cooler. Shower potential with a frontal passage around August 28.

  1. Thanks, TK.

    Warm day in Muswell Hill (section of London where I’m staying). But I can’t say it’s hot or particularly humid. Locals are complaining. I think people complain about the weather worldwide. It’s universal. Heck, I bet you there are folks in San Diego who moan about the weather.

    1. I always have and always will find it funny that folks complain about the very thing that keeps humanity able to live here.

    2. Agree that weather is a universal topic and everyone wants to talk about it. What’s interesting is that the same person will complain … it’s too hot, too cold, rainy, humid, snowy, windy, etc.

  2. Good morning and thank TK
    Decent thunderstorm yesterday evening. It was really getting going as it passed over head and was a monster South of here.
    Many lightning strikes nearby, a few less than 1,000 feet away.

  3. Invest 98L moves into Texas today. It’s great news as it brings beneficial rain to drought areas!

  4. WBZ radio big booboo.

    They literally just reported that Hurricane Erin is heading for Puerto Rico this weekend and may clip the Dominican Republic.

    No.

      1. I love that phrase JP Dave!! I may use it to describe my NY Mets baseball team these days..

  5. Erin: Been wondering for 2 days whether Erin might hit Newfoundland, but today I am thinking not.

  6. re: Wordle
    5 for me today. A couple of possible correct words that were wrong guesses as there was nothing Weird about today’s word.
    Oh well. My Guess, Sclarke in 3, all others in 4, except for me, of course.

      1. I had high hopes for guess 3 and guess 4. IF I only tried my 5th guess, on guess 3 I would have done it. But, NOPE!
        I had to accept 5. At least I got it. that is something.

        1. Snuck out a 3 today on Wordle. I only had one correct letter on my 2nd guess and somehow guessed the right word. Pure luck!

    3. Awesome job for all. 5 for me too. I’ve been tracking letters used most often since July 25. I tried two new first words based on that. I had nothing for my second word. So much for trying to figure Wordle out. Although I’ll keep tracking for a bit

  11. Now that it’s light out, I can see in my backyard that last night’s storm took down a couple of very large branches. One just missed a shed we have in the backyard, and the other landed about 20 feet away on top of some hydrangeas we planted a few years ago, as well as an area we set up near our pool with a firepit and some chairs.

    1. Pretty impressive central pressure for this latitude!!!

      Too bad the ICON is NOT a reliable hurricane model.

      1. Exactly re: ICON

        The subtropical part of the Atlantic east of central FL north to east of maybe Wilmington, NC has significant positive SST anomolies.

        So, assuming major westerly and northwesterly sheer hasn’t kicked in to cause the significant curve east northeastward, it could be extremely strong pre curve.

        1. Yes indeed and if that re-curvature is delayed for any reason, then North Carolina could be in line for a hit
          or a good graze. Something to watch.

            1. Wow.

              In the one term our oldest went to FAU in Boca, we moved her in, in late August.

              Went to the beach and it was the weirdest feeling ocean water, just so warm. It didn’t offer one bit of cooling.

  23. Other than Erin … which isn’t touching any land … and a disturbance about to bring needed rain to Texas … it’s back to the snooze fest in the tropics for Atlantic & eastern / central Pacific. Oh yeah, also include the ENTIRE western North Pacific and Indian Ocean! Zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz.

  24. A lot of shrinking / disappearing of “above normal” temp forecasts on CPC’s maps heading through the next 4 weeks.

    6-10 & 8-14 are still below normal for our area.

    Interestingly, but not surprisingly (to me), this coincides with an Atlantic Nina, which mimics a -AMO (even though we remain in the long term positive phase overall). I become more and more convinced that the AMO plays a very significant role in long term climate patterns not just here, but globally. Combine this with the ongoing HT Effect (which has many years left in it and is being found to be having even more impact that originally thought), and the countless other things that impact it all … the atmosphere is a complex thing.

  25. I thought I posted this but hmmmmm. I thought our soccer fans here might be interested.

    My nephew just shared some exciting information. His daughter is very active in soccer. My grand niece made the NE Regional team for the Olympic Development program (ODP). She’ll be going to Florida in January to play against the three other regions to potentially make the 2010/U16 National team

  26. 82/61. Ahhhhhhh. For the first time this week I’m not seeing any 90s on the nws map. Doesn’t mean there are not any. But they have dotted the map

    1. There are none. We’re in a very different air mass now. 🙂

      Next 90+ for the region will be Sunday – a one-day stand, then a long stretch of below normal temps follows. 🙂

      1. I figured there were not any but don’t like to guess. Lots of heat waves broken. Fine with me. I’m surprised how much it’s taking out of me.

  29. Thanks, TK.

    A more typical London summer day today: Cloudy with light mist at times, 69F. Will go down into the low to mid 50s tonight.

    It’s going to be very hard to return to Boston. I feel quite empty at the thought.

    1. Depending on when your returning, after Sunday, thanks in part to Hurricane Erin, many days next week will be September like.

    1. For now, a quite compact system but it’s wind field will be expanding in the coming days.

    2. Warmest surface water during its entire existence + much less hostile atmospheric conditions.

  31. The Islands were lucky it did that jump the other day northeast or this would have been a problem.

  32. Tom, I fly back to Boston on Friday, the 22nd. I believe the weekend after I arrive will be warm. But then, per TK’s forecast, it looks like the period after that will be cooler.

    I’ll be fine. It doesn’t take long to adjust to Boston, not just weatherwise. It’s a fine city. A miniature London in some ways. My bigger issue is emotional. My daughter lives in London. I’ve been lucky to see here several times a year, and sometimes for long stretches. But 3,200 miles is a long distance. I’ll also miss being here. It’s the most I’ve ever felt at home, anywhere in the world. And I’ve lives in plenty of places.
