DAYS 1-5 (AUGUST 23-27)

Our unsettled weekend rolls on, but this is a weekend where clouds dominate much more than rainfall. Yes, there were areas of drizzle and showers yesterday while the bulk of steadier, heavier rainfall stayed offshore to our southeast. This morning, a batch of rain and embedded thunder is moving through southwestern New England as of sunrise and will slowly start to shrink as it moves northeastward into and across the WHW forecast area this morning and midday. Behind this area we see some partial clearing which can fuel the atmosphere for some isolated to scattered showers and thunderstorms later in the day. While coverage will be limited, we do have to watch for isolated occurrences of stronger to possibly severe storms before activity diminishes with the setting sun. A broad trough of low pressure, as previously mentioned, still needs to make its way across our region from west to east through Tuesday. This keeps the chance of a shower or thunderstorm in the forecast for Monday afternoon and an additional shower chance Tuesday, with activity both of those days more likely west and north of Boston. High pressure builds in with wonderful summer weather Wednesday into Thursday, but we need to watch for the potential for a shower or thunderstorm by later Thursday, at least in western areas, with the approach of our next trough / disturbance.

TODAY: Generally cloudy morning with showers and a possible thunderstorm moving southwest to northeast across the region, diminishing in coverage with time. Clouds break for partial sun this afternoon including the chance for an additional shower or thunderstorm later in the day. Highs 71-78. Dew point 60+. Wind variable up to 10 MPH becoming S.

TONIGHT: Partly to mostly cloudy. Patchy fog. A shower possible. Lows 62-69. Dew point 60+. Wind SW under 10 MPH.

MONDAY: Variably cloudy. Scattered afternoon showers and thunderstorms possible, mainly west and north of Boston. Highs 76-83. Dew point in 60s. Wind SW 5-15 MPH.

MONDAY NIGHT: Variably cloudy. Chance of a shower. Lows 61-68. Dew point near 60. Wind W up to 10 MPH.

TUESDAY: Partly sunny. Chance of a shower, mainly north and west of Boston later in the day. Highs 77-84. Dew point near to below 60. Wind W 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 60-67. Dew point falls to 50s,. Wind W 5-15 MPH.

WEDNESDAY: Mostly sunny. Highs 80-87. Dew point 50s. Wind W 5-15 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 60-67. Dew point 50s. Wind W under 10 MPH.

THURSDAY: Sunny to partly cloudy. A late-day shower or thunderstorm possible mainly western areas. Highs 81-88. Dew point around 60. Wind SW 5-15 MPH.

DAYS 6-10 (AUGUST 28 – SEPTEMBER 1)

Shower and thunderstorm chances early August 28 and around August 30 or 31, otherwise a mainly rain-free pattern. Temperatures near to above normal.

DAYS 11-15 (SEPTEMBER 2-6)

A couple disturbances may induce shower chances, but fair weather the vast majority of the time. Temperatures near to slightly above normal.

  5. Nice amount of rain, SClarke, and super 3

    I thought we were low with 0.03 yesterday and 0.02 so far today. You have me beat JPD

    We had 0.12 Thurs and 0.14 Fri

    And 5 years ago we had TS Henry. What was the one before Henry? She poked a hole in our foundation and poured into our basement. We been down in the basement because of a tornado warning, which turned out to be a good thing we never would’ve seen the leak. I believe it was 4 inches. We had in a very short time.

    1. Something I collect (besides photos of vanity plates, and bottles caps, and music) includes really bad disaster movies. My son and I like to “MST3K” the movies while we watch them occasionally as part of our media sessions. Once in a while we’re pleasantly surprised by a “better” one that sneaks in there, but most of the time it’s just having a grand old time picking them apart. 🙂

  9. My nephew is in Yuma, AZ for work. Yesterday was 115 F with DPs in the upper 60s. It’ll be like that for the coming week at least.

  10. I can’t begin to imagine 115 and high DPs. Yuk

    And I think you sent your rain here. It’s a lovely soft rain and up to 0.21 and gaining. Lightning to my west.

  14. While the temperature is down the dewpoint most definitely is not. Still very sweaty out there on my run. 68F and a dewpoint around 50F would be better.

    1. Definitely didn’t expect dry air to accompany a southerly flow from the subtropical regions. That’s ours today. Tomorrow, we begin a 3-day dry-out on a (mostly) westerly wind. 🙂

  16. We have a pretty solid muggy & warmer feel upcoming mid to late afternoon as we start to bring intervals of sunshine into the picture. This is when we will have to watch for the development of thunderstorms, possibly strong, but not widespread, as noted in today’s discussion.

    This morning’s rainfall behaving about as expected. Slow eastward movement of area, more rapid northward movement on elements (merged convective cells and spread). Net motion is northeast. The area lifts out to the north more than it departs to the east, and this is followed by the partial clearing. Sox game will get in today, but we do have to watch for the aforementioned shower or t-storm later, depending on if/when/where formation occurs.

  17. The Colorado River Decision

    I have been following this off and on since last summer.

    The river serves 7 states and something like 40 million people. The current usage agreement was expiring and the 7 states couldn’t agree on a thing among themselves.

    The Feds stepped in and sort of got a 2-year agreement. The so called 3 Lower Basin states … Arizona, California, and Nevada … agreed to cut usage by 1.25 million acre feet of water per year for 2027 & 2028. The Upper Basin states … Colorado, New Mexico, Utah, and Wyoming … are spared mandatory cuts for some reason.

    Meanwhile Lake Mead, a reservoir along the Colorado River which can hold 9+ trillion gallons of H2O, is somewhere around 25-30% of capacity. Not good!

    Arizona got walloped with a reduction of 750,000 acre feet of water for each of the next 2 years.

  19. From Pete.

    Have you heard dire warnings about the impending Super El Niño forming in the Pacific this year? Here’s what the science says about whether this rule-breaking pattern is all hype or if we’re in for a crazy fall and winter, and just what El Niño is anyway. https://on.nbcboston.com/uMgzV6V

    1. Thank you. Nice job Pete.
      We shall see as there are other factors that govern our Winter Weather and we are not all that far from the cold.
      Could be interesting.

  22. This morning had our first 6:00 am sunrise. 🙁

    The mornings only get darker from here and with the now year-round DST, real morning light won’t occur until mid-morning times once we get into the depths of winter.

    As inconvenient as it is changing clocks twice a year, I’m going to miss that ritual, especially in the fall.

      1. Current Status of the LegislationThe U.S. House of Representatives passed the Sunshine Protection Act, which would make Daylight Saving Time permanent nationwide.The bill requires approval from the U.S. Senate and the signature of the President before it can become law.The Senate has not yet scheduled a vote on the measure.

        1. It’s not happening anytime soon. I don’t know why everybody seems to think it’s a done deal. It’s not. And even if it is, in the future, it won’t last, once they see the same results (or worse) than what happened in 1974.

          Not sure why the collective memory lapse here (in general, not WHW) about how badly that went when we did it before. I think we are well aware of how it went last time unless we were not around for it. 😉

          1. I definitely remember how detested it was ….by a large enough number of people to have it changed.

            I was also curious to know if it was going to go into effect, I never thought it was a done deal. Im smart enough to know that whatever this administration wants is what’s gonna happen regardless of whether it’s done so legally?

            1. Exactly. I’m not sure why there seems to be a pretty widespread belief that it’s already set in stone. I think it was how the headlines were presented on social media – for clicks and shares, of course. 🙂

          2. Replying to my own comment to finish the rant…

            The fact we actually make such a big deal out of this is comical. We live on a nearly spherical object, that wobbles while orbiting another nearly spherical object at exactly the right distance so we can actually exist. It provides us everything we need here to survive. Yes, it can result in destruction, but it also results in creation, and sustenance. Depending on where you are on the earth will determine, without any control from us, how much light and dark you experience. That’s just a fact. What we do with that time is our choice. How we measure it is also our collective choice, obviously not going to be agreed on by all, but that’s just how it is.

            We know all of the impacts, mentally, physically, and otherwise, that too much or not enough can result in. And it’s up to us to adapt. That said, there are things we can choose to do or not do in the shorter term that we know will have benefit, or lack thereof. And that should be our focus in the “now”, while we live as we do.

            Do I think a sunset at 5:11 p.m. on December 15 after a 8:30 a.m. sunrise is better than a 4:11 p.m. sunset after a 7:30 a.m. sunrise? Absolutely not. Not for what we do as a society, especially regarding our children’s school times.

            Yes, we could change the school hours during the year to accommodate, but how different is that than just keeping the twice a year time change we have now? Yeah…

            Best bet: Keep it as it is now.
            Next best bet: Standard time year-round.
            Worst bet: Daylight saving time year-round.

            And the third one of those may be the most likely to be our next step. Why am I not surprised? 😉

  26. We had a BBQ planned for 2:00 today and the weather cooperated just as expected!

    We ended up with 0.59″ over two days.

  27. When I was a graduate student, I worked with a visiting mathematician from Czechoslovakia. He refused to change his timepieces during DST. Instead, he shifted the times that he did things by one hour so that he was in agreement with everyone else. 🙂
