DAYS 1-5 ( JULY 24-28)

Despite an active pattern in the last few weeks with frequent episodes of showers and thunderstorms, we have managed to find ourselves in a basically unchanged “abnormally dry” to “moderate drought” status according to the latest Drought Monitor data. There are exceptions – a portion of southeastern MA, eastern CT, and Nantucket, that are not showing any significant dryness at this time. However with no switch to a pattern that is going to provide a series of widespread, beneficial rainfall, I don’t expect much to change over the next few weeks, and we may yet seen an expansion of dryness in the longer term. We will revisit this, but now to focus back on the regional weather in the shorter term, i.e., the next 5 days. The cold front that brought another round of thunderstorms to a good portion of the region yesterday sits just offshore this morning. Some higher level moisture is still streaming northeastward and will be responsible for a fair amount of high and some mid level cloudiness for a while today, though we will see it move out eventually. In addition, the lower level air flow only being weakly from the north will allow for some sea breeze development during the afternoon, and these may provide enough convergence to pop a few showers mainly across RI, eastern CT, and adjacent areas of southern MA, so I cannot make today a totally dry forecast for the southeastern New England region. I can do that tomorrow though, as a dry and stable air mass will be in place as high pressure centered over the Great Lakes extends itself into southern New England. This keeps winds light enough so that we may again see some sea breezes, but not enough moisture for any showers. Want more summer heat? Regardless of your answer, it’s coming back Sunday and lasting into early next week. This will come along with an increase in humidity once again as high pressure moves to the south of New England. A series of troughs approaching from the north will provide an increasing risk of mainly afternoon and evening showers and thunderstorms Monday through Tuesday, though that risk may come down a little bit on Wednesday as slightly drier air sneaks in behind one of them. That’s a detail I’m not confident of yet.

FRIDAY: Lots of clouds with limited sun morning. Fewer clouds with more sun afternoon, but isolated showers possible eastern CT, RI, and nearby southern MA. Less humid. Highs 78-85, coolest coastal areas. Wind N up to 10 MPH except coastal sea breezes developing.

TONIGHT: Partly cloudy southern MA southward with a slight risk of a shower early, otherwise mostly clear. Patchy fog forming in lower elevation areas (valleys, swamps, riverbeds, bogs). Lows 56-63. Wind variable under 10 MPH.

SATURDAY: Mostly sunny. Highs 82-89, cooler in some coastal areas. Wind variable up to 10 MPH except some coastal sea breezes developing.

SATURDAY NIGHT: Mostly clear. Patchy fog interior lower elevations. Lows 60-67. Wind variable up to 10 MPH.

SUNDAY: Mostly sunny. More humid. Highs 86-93, cooler Cape Cod. Wind W 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Humid. Lows 66-73. Wind W up to 10 MPH.

MONDAY: Sunny to partly cloudy. Slight risk of isolated thunderstorms late in the day. Humid. Highs 90-97 except cooler South Coast and Cape Cod. Wind WSW 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Slight risk of a shower or thunderstorm early. Humid. Lows 68-75. Wind SW up to 10 MPH.

TUESDAY: Partly sunny. Scattered showers and thunderstorms, mainly afternoon and evening. Humid. Highs 88-95 except cooler South Coast and Cape Cod. Wind SW 5-15 MPH.

DAYS 6-10 (JULY 29 – AUGUST 2)

Warm to hot with a risk of showers and thunderstorms July 29 then a push of drier air is possible by July 30. Still uncertainty but cannot rule out a cooler/unsettled final day of July if we get low pressure south and high pressure north to set-up. Improvement would follow for the August 1-2 weekend. Still a lot of tweaking potential with this part of the forecast.

DAYS 11-15 (AUGUST 3-7)

Mostly zonal flow, seasonably warm to hot weather and a couple shower and thunderstorm opportunities.

  3. Good morning and thank you TK.

    All I can say is UGH!!!!!!!!!!!!!!!!!!!!

    Bring on September and the sooner the better.

  4. So TK, you were parked in the Meditech parking lot in Canton yesterday. That brought back some terrible memories. I spent
    much time in that building.

    On a somewhat related weather note:

    That building came with a sophisticated Energy Management System. When we purchased and took over the building from the Codex Corporation, we found that the EMS (energy management system) was not fully utilized. For cooling the building our facilities staff would have to manually turn on
    the chiller (a sophisticated cooling system where the unit
    chills incoming water and pumps out cold water which is used
    to cool the building). There were many valves that had to be opened and closed in this process to make it all work.

    I sat down and wrote a computer program to automatically
    close and open values and turn on and off the chiller. The system had access to various temperature readings throughout the building, so I built in decisions in the program to turn the system on and off based on temperature readings. Once that
    was fined tuned, I enhanced it by setting thermostat settings
    based on how humid it was.

    For example if it was warm, but dry. I would set the building
    to lets say 74. next level of humidity I would set it at 73
    and for the most humid conditions, I would set it at 72. I don’t remember the exact settings, but you get the idea.

    Believe it or not, it worked like a champ.

    That’s what you get for dredging up memories.

    1. Dave …
      The folks at that building I was at were nasty to my son. Before the storm, be was under the entry awning to test his high quality recording device and when the lightning core got close I advised him to stay undercover there until it passed and I could safely pull up to get him.

      Well, some lady id’ing herself as a “CEO” ordered him to leave and when he said his father asked him to wait out the lightning and that he would vacate the moment he felt it was safe, she called someone else down to assist in the order. They forced him out into the open. Thankfully he was able to get a text to me and I got up as close as possible.

      That solidified my dislike for that place. They have received a pair of one star reviews on Google as a result.

      1. That sounds like them. I loath that place.
        Sorry you had to see that. I have been too far removed from there, so I have no idea who that lady was. The CEO is a man. The COO is a woman, Michelle O’Connor. Never knew her.

        1. Maybe that’s who it was. She spoke nastily to my son, who was very polite to her. Heartless dipcraps. Whatever happened to just being nice? Everywhere you go now, somebody is waiting to be a jerk to you or throw you out of somewhere. Anyway, that place will never get a favorable word said about them from me after that and the other stories I’ve heard.

          1. I’d love to hear the other stories. Perhaps you could email me as I am sure you don’t want to do that
            in this forum.

      2. Tell Nate not to feel bad as in general, the management
        of that company isn’t very nice at all. I am not surprised
        in the slightest.

        1. Sadly I don’t know all that many “managers” that are nice these days. As soon as they get that position they suddenly feel superior to the rest of humanity.

  5. I never thought I would ever say this but I’m actually looking forward to the cooler/unsettled July 31st.

    1. Thanks North. Not really. I have been coding computers
      since I was 19 and that with some weather knowledge
      it made the task relatively simple. 🙂

  11. NE wind at the airport.
    North Wind inland. Enough for some convergence as per
    TK’s post? Time will tell.

  13. Not sure I said thank you and I’m sorry. It’s been one of those days

    THANK YOU VERY MUCH!

  14. Tropical storm Hanna could become a hurricane before making landfall in southcentral coast of Texas tomorrow. Rather impressive how large this system is.

  16. Keep an eye on that wave in the eastern Atlantic. Not saying it’s going to do anything at all, but there’s enough of a signal on the Ensembles, especially the ECMWF Ensemble that it *could* be a threat to parts of the US in about 9-10 days. I’m not buying it completely yet, but it definitely has my attention.

  17. This morning’s sunrise was 5:30, a loss of 23 minutes since the earliest sunrise (5:07). Not “too” noticeable just yet.
