DAYS 1-5 (JULY 22-26)

Wet pattern: Gone. Frequently high humidity: Gone (for now). Wildfire smoke: Mostly gone. The pattern change we’ve talked about is well-underway, and essentially complete. This new pattern won’t last forever either, but it will be with us long enough to dry out nicely in the days ahead, despite the fact that we still have to deal with a couple disturbances and shower chances. But first, high pressure from Canada brings us our nicest day in quite some time today. You’ll notice the sky a deeper shade of blue as the smoke plume that was passing through has moved off to the southeast, and the next area of smoke stays well to the west, at least through Friday before we may have to deal with some of it once again at some point over the weekend. A disturbance will pass through the region Friday and combined with daytime heating will likely generate diurnal showers, which look like they will be only isolated in coverage, but could produce brief localized downpours in some locations, but this is still an improvement over what we’ve had. This will be followed by another Canadian high pressure area and more great weather Saturday. Our west northwesterly air flow will bring the next disturbance toward the region for Sunday into Monday, a warm front / cold front combo. The warm front will move across the region Sunday with a lot of clouds and a round or two of showers, though that day will be far from a “rainy day” as there will be dry times too. The cold front moves through sometime during the first half of Monday based on current timing, and may bring a few showers and thunderstorms, but again this looks like a much lower coverage event than many we had seen before. Higher humidity will accompany the unsettled weather Sunday-Monday, but not looking for oppressive conditions.

TODAY: Sunny start, then a sun/cloud mix. Highs 76-83. Dew point ranging from middle 50s to lower 60s north to south may lower a little more during the day. Wind NW 5-15 MPH.

TONIGHT: Partly cloudy. Fog patches forming interior lower elevations. Lows 56-63. Dew point lower to middle 50s. Wind NW under 10 MPH shifting to W.

FRIDAY: Partly sunny. Isolated showers and a slight chance of a thunderstorm in the afternoon. Highs 74-81. Dew point middle to upper 50s. Wind W 5-15 MPH shifting to NW.

FRIDAY NIGHT: Mostly clear. Patchy ground fog lower elevation areas. Lows 55-62. Dew point middle 50s. Wind NW up to 10 MPH.

SATURDAY: Mostly sunny. Highs 76-83. Dew point upper 50s. Wind W 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Lower elevation fog patches. Lows 57-64. Dew point upper 50s. Wind W under 10 MPH.

SUNDAY: Variably cloudy. Chance of showers. Highs 76-83. Dew point lower 60s. Wind W 5-15 MPH.

SUNDAY NIGHT: Mostly cloudy. Chance of showers and possibly a thunderstorm. Patchy fog. Lows 62-69. Dew point lower to middle 60s.

MONDAY: Partly sunny. Chance of showers and possibly a thunderstorm, favoring the morning-midday hours. Highs 78-85. Dew point lower 60s. Wind W 5-15 MPH shifting to NW.

DAYS 6-10 (JULY 27-31)

A west to northwest air flow pattern will feature drier than average conditions and near to below normal temperatures, often seeing air coming from Canada. Best chance for an interrupting disturbance with showers around July 28-29.

DAYS 11-15 (AUGUST 1-5)

Overall pattern of west to northwesterly air flow, with no major heat, temperatures near to slightly below normal, and a drier overall regime with limited shower chances.

  1. Good morning and thankvyou TK.

    Missed all activity last evening, but was really close to the one that got downtown and the harbor.. I’ll bet Logan got closer to the July record.

    1. Nope, looks like Logan missed as well. It went through the city and into the Harbor between my location and Logan. 🙂

      I’ll bet Joshua got some of it.

  3. Thanks TK. Entire forecast looks great for those trying to dry out and for rivers to lower. Refreshing out there this morning, compared to the higher humidity that seems like it’s been here for weeks. Makes us appreciate more those nice Canadian air masses we had back in some parts of May and a couple of small stretches in June!

  5. Thanks TK
    My kind of summer weather the next three days to get out and enjoy open the windows and save a few bucks on the electric bill not having to run the AC.

  7. Thanks, TK.

    No rain here in Back Bay last night. So the blob of rain must have somehow missed me. Did get a shower late yesterday afternoon, but nothing more than a trace.

  8. It was one month ago today, June 22nd, I believe, that we had a really comfortable day like today. We were camping then, like today. We’ve been plopped on our site all morning and it’s been awesome to feel this comfortable breeze and breathe in the fresh air.

    1. I loved your positive approach last month but am so happy for you to have this perfect weather this month

  9. Last night’s convection was very narrow in city limits then expanded out over the water…

  10. SSK, I was thinking.

    I’m addition to TK’s excellent forecasts, if your still trying to make a decision on Hampton, check out WMUR

    WMUR, ch 9 out of Manchester is very good. It’s the sister station of ch 5 Boston and especially during summer, part of the forecast is focused on Hampton Beach.

    1. Oh I’m definitely going Tom I already paid for the condo . We usually go Saturday- Saturday I was able to pay an extra $100 & get in tomorrow . The plan is to arrive by 3:00 . I do need to leave the beach for the day Wednesday for a funeral in Quincy. How’s it looking Tom , thanks buddy

      1. Sorry to hear about the funeral you are attending Wednesday.

        Looking at TK’s forecast and the models, I think Saturday, Monday, Tuesday look really good ! Tomorrow is good too, but may have a brief afternoon shower and Sunday may not have a ton of sun, but the humidity will have it feeling like summer. Have a great time !!

  12. Stepped outside just now and got a few raindrops on my head, similar to yesterday afternoon. Cloud formation above Back Bay is beautiful. Every kind of cloud is up there, including a rather massive, dark, rain-filled cloud.

    1. It’s now raining. Not just droplets. I’ve counted 2 days this month that were totally rain-free.

  13. Some short range guidance actually had these showers today. Most did not. I chose the optimistic route in the forecast. Eh…

    At least they’re isolated.

    1. As long as they are sprinkles. I sprayed pesticide outside today, since it needed to be mostly dry. Have had these annoying harmless things called springtails making into the house mostly on windowsills. Never had heard of them before but hate anything making it into the house :).

        1. Those are blown up pictures, lol. They are really tiny and don’t harm anything, annoying nonetheless.

  15. I was not expecting a rain delay in the Yankees Red Sox game tonight. It is July 2021 so should we be surprised it is raining

    1. Yes, when it `wants’ to rain it will rain. Rain appears to have stopped, but that was quite a shower. The question is, will the 1921 record stand in Boston? Based on medium and long-term guidance, it would appear the record will not be broken. But, with 9 days to go, one never knows.

  17. From NWS discussion: “Unsettled pattern returns Sunday with chances for showers and thunderstorms each afternoon.”

    Just how many afternoons is Sunday planning on having? 😉

      1. Nope. It was a typo or a “oops forgot to change something when editing an older version”. I just thought it was funny to read. 🙂
