DAYS 1-5 (JULY 20-24)

High pressure will have weak control of our weather during the weekend. What do I mean by weak control? Well, where yesterday was just a straight up fair weather day with dry air, abundant sun, a few fair-weather clouds, and a nice sea breeze with high pressure in firm control, we have other things to contend with this weekend. The high center weakens a little and slides off to the southeast of New England today, allowing a weak warm front to lift northeastward toward the region. While some diurnal fair weather clouds can pop up still, above this we’ll have considerable high level cloudiness and some patchy mid level clouds fanning in from the west southwest and filtering to dimming the sun. During the day today the dew point that was in the 50s yesterday will edge back up to the lower 60s, but this is still fairly comfortable, especially in comparison to the high humidity that preceded this drier air for many days. There may be just enough mid level moisture passing through tonight to generate some very light rainfall in areas mainly to the south of I-90, but this will exit the region by dawn Sunday, and the day will be pretty nice overall, with just some patchy clouds and low to moderate humidity. A weak cold front will drift down from the north but isn’t really expected to have any impact of note, other than adding some clouds to the sky. What’s left of this front washes out over the region Sunday night into the early part of the coming week. As we get into next week, Monday-Wednesday, expect the pattern to feature an increase in humidity and shower chances with a more established southwesterly air flow returning. The difference this time is that we’ll do this without the return of major heat, just more seasonable warmth.

TODAY: Partly sunny. Highs 81-88 except cooler in some coastal locations. Dew point rising from middle and upper 50s to lower 60s by day’s end. Wind variable to S up to 10 MPH.

TONIGHT: Variably cloudy. Sprinkles of very light rain possible south of I-90 and patchy fog possible over interior lower elevations. Lows 60-67, coolest over inland valleys. Dew point lower 60s. Wind W to SW up to 10 MPH.

SUNDAY: Partly cloudy. Highs 82-89. Dew point lower to middle 60s. Wind SW 5-15 MPH.

SUNDAY NIGHT: Partly cloudy. Patchy fog. Lows 61-68. Dew point lower 60s. Wind variable up to 10 MPH.

MONDAY: Partly sunny. An isolated shower or thunderstorm possible, especially south of I-90. Highs 79-86, coolest coast. Dew point lower 60s. Wind variable to SE up to 10 MPH.

MONDAY NIGHT: Partly cloudy. Patchy fog. Lows 61-68. Dew point 60+. Wind SW up to 10 MPH.

TUESDAY: Variably cloudy. Showers and thunderstorms become more likely. Highs 78-85. Dew point middle to upper 60s. Wind SW 5-15 MPH.

TUESDAY NIGHT: Mostly cloudy. Scattered to numerous showers and possible thunderstorms. Patchy fog. Lows 65-72. Dew point 65+. Wind SW to variable up to 10 MPH.

WEDNESDAY: Partly sunny. Showers and thunderstorms possible, but may favor the morning hours. Highs 79-86, cooler in some coastal areas. Wind variable up to 10 MPH.

DAYS 6-10 (JULY 25-29)

Higher humidity and shower chances in the July 25-26 period before drier arrives for the weekend and higher humidity makes a comeback at the very end of the period. No prolonged major heat, but temperatures may be notably above normal again by late period.

DAYS 11-15 (JULY 30 – AUGUST 3)

Moderate to higher humidity returns along with a few shower and thunderstorm chances, but not an excessively wet pattern. Temperatures near to mostly above normal.

  1. Good morning and thank you TK

    Made 81 yesterday with an overnight low last night of 65

    Currently 74 with dew point 61

    Ocean temperature: 62.2 (Boston buoy)
    That temperature just refuses to go up despite the warm weather.

    1. I spent yesterday at the beach (Hampton NH) and the water was very, very chilly. Lots of upwelling takes place when we have a lot of southwest air flow, which we did over the last few weeks, so it’s become a quite established chill along the coast.

      And even though we’ve been pretty warm, it hasn’t really been excessively hot (just very humid). I mean, how many records have we challenged, never mind broken, this summer, for high temps? Example, our hot stretch last week included 2 highs of 95 at Logan. The records for those days were 98 and 99. Hot? Yup. Record heat? Nope. 🙂

      1. Agree on the heat, but it has been above average in the temperature department none-the-less.

        South of RI, which would take the brunt of the south westerlies, the water remains warm in the 73-75 range.
        I don’t understand that.

        It just baffles me that our water here on July 20th ISN’T any warmer than it was on June 2nd or 3rd. Amazing.

        1. The ocean is an interesting “atmosphere” all its own. And while there is solid interaction with the air above it, it’s quite the established system itself.

          If nothing else, this is a good example of how non-linear things are in weather and nature.

          Society (and media) tries to oversimplify things to the point there’s very little learning to be done, and so focused on a couple things that so many things get left out. That’s a shame.

          1. It certainly is. I monitor that water temperature daily.
            It certainly goes up in the lighter wind days. 🙂
            But comes right back down with wind.

            I just wonder if we have a little Southern extension
            of the Labrador current going on as well?

            1. That’s possible. “Pieces” of main currents can break off and visit areas outside of their typical pathways.

    1. Sounds special. I had to look to see where Mt Major is. Around the Alton Bay Area?? Views of the lakes with mountain backdrops must be spectacular

      Enjoy!

  10. Not sure if annyone has views to share. And it may be a busy Saturday but I’m curious about views. I did ask TK if it is all right to post here.

    NOAA was created by Nixon in 1970 and is under the Commerce Department. There is current discussion of moving NOAA to its own agency. It was first mentioned a bit over a year ago but seems to be back in the news. I think we can discuss without pointing to one party or the other as there seems to be pros and cons on both sides.

    I tried to find links that represent different views.

  11. There’s a new Progressive insurance ad that features the guy who tells us “Progressive can’t keep you from becoming your parents.” This one depicts people who are into meteorology, checking weather apps, looking outdoors at different types of clouds, talking dewpoint and percentage chances of precipitation. I’m clearly one of those people. Just as I am one of the people in the other Progressive ads that are constantly being mocked. Am I offended? No.

    1. I’m not familiar with progressive ads. The only reason I saw this one is because a weather person I follow shared it. Can’t recall who that person was. It could have even been on whw. I’m not offended either. It was kind of clever.

    Has it been more humid than normal this July or is it “just summer”?

    It’s been more humid than normal for about 70% of the U.S. so far this July.

    The most unusually humid conditions have been found from Washington D.C. northward into New England, where average dew points have been more than 5˚F above average in parts

    For some, this has been one of the most humid stretches on record, such as by consecutive days with a maximum dew point above 70˚F.

    If it’s not very humid where you live right now, such as in the Northeast, enjoy it, because it will be back next week…

  17. Yesterday was the first day since July 3rd dew points were in the 50s where I am. Today dew points mid 60s which does not feel too bad considering where the dew points have been the past couple weeks.

    1. I don’t know if we got to 50s but we were in the lower 60s today till I just looked. We are 67 with a temp of 79

      It’s darker here but northern part of the cell /line that we might get is fizzling ….what else is new.

  20. Fewest amount of named tropical cyclones (6) in the entire northern hemisphere to date (July 18) since 1969.
