1. Good morning and thank you TK. My wife and I could both
   feel the humidity increasing over the course of last evening.

   I would like to place an order of dry weather please with High dew points NEVER to return. Thank you.

   This Summer was the first time ever that the high Dew Points made me ill.

   1. Second that order for low dew points. We’ll rejoice one crisp September day. It’s around the corner at this point.

      I used to love heat and humidity, but that was a loooooong time ago. My body no longer tolerates it. I feel physically ill when the dew point is high.

      1. You sound just like my wife. She gets physically ill as soon as
         the dew point crosses 60 and when it’s in the 70s she’s forget about it. Just brutal!! Luckily we have a couple
         of rooms with AC, so that only allows her to survive.
         I am certain without AC this weather would kill her.

         I never experienced illness from it until last week when the DP was 75.

         Let us hope this crap is done with us really soon.

         Hope you feel better as well.

         I think we need to move to London.

         1. According to Dave Epstein this morning, there are no “average” temperatures in sight. His exact words btw. We are going to be in the HH air for the long haul.

            As for London, I thought I heard just yesterday or the other day on the radio that much of Europe is very HOT right now.

            Maybe Joshua can verify?

2. Thank you, TK!

3. Thanks TK
   5.1 magnitude earthquake in North Carolina this morning.
   https://www.wxii12.com/article/51-magnitude-quake-rocks-north-carolina/33555174#

   1. Yikes. Thanks JJ.

      1. For this part of the country that is an impressive earthquake. The last big earthquake I remember in the eastern U.S. was back in 2011 which was 5.8 which was felt in parts of CT with the epicenter in northern VA.

         1. It tied the largest they have had….5.1 in 1918…from what I can see. They are not regular in NC but most are in the mountains which makes sense and also where this one seems to be

            https://www.wbtv.com/2020/08/09/did-you-feel-it-magnitude-earthquake-reported-near-sparta/

         2. Was that the one around DC? If so it was felt in Boston and very clearly in the house we were in on Humarock.

            1. It sure was felt in Boston! I was at work and my desk
               was rocking!

4. Thank you, TK

5. Yes the 2011 Earthquake was around D.C. If I remember correctly the Washington Monument had to be shut down for a while is damage occurred with that earthquake.

6. Philip, you are correct. It is hot in London and much of Europe. Been that way for a few days and that will continue for a couple more.

   1. Sure once in a while it gets hot in London, but for the most
      part it is very temperate. Much much much better than
      here!

7. It’s funny though for such a hot summer it hasn’t actually been that hot. We’ve had a lot of very warm days and lower 90s days. We’ve had very few extreme heat days.

   And we also continue to get a lot of east wind keeping the coast modified. The main reason why the water temperatures are so warm this season. I will finally get to enjoy some of that myself a little later this month. 🙂

   As far as the earthquake, we have very different types of fault lines in the East as compared to what you find at the Pacific Coast. although fairly infrequent there can be some pretty significant shakes especially in the Appalachians.

   1. Sure the coast, but I am 5-6 miles from Logan and it is
      totally different here. Days were Logan tops out at 78 or 79,
      we’re 90-92. And even though there haven’t been many
      upper 90s days, the humidity has been out of control.

      1. Humidity has been up there at times, for sure, but my goodness I’m not sure if anything will compare to the relentlessness of 2018’s.

         1. That may be, but for my wife and I and most especially my wife, the humidity is getting worse as we get older.

            1. I mean the effects are getting worse.

               1. Same thing happens with my mom as well. I still have to remind her to take AC breaks. She tries to do her usual routine day after day, the same way she did it when she was raising 5 kids. 😉

                  1. Yup. My wife finally learned that she cannot
                     do her usual routine during this type of weather.
                     I try to help out with the laundry and preparing
                     meals etc.

                     Hope your Mom is hanging in there ok.

   2. Tk it’s been a humid summer translation it’s been a hot summer without extreme hot days . Between wearing a mask outside at work in the city & the humidity I’m struggling a lot this sunset & that is very , very rare for me

      1. This summer

8. Thanks TK !

9. Providence @ +4.7F for August, Worcester @ +4.8F, Hartford @ +3.8F, Logan @ +2.9F

   I think, this warm season, the post frontal air-masses have been warm themselves, with the difference being temporary drops in the humidity. The post-frontal airmasses have been accompanied by light winds, which has initiated a lot of seabreezes or outright onshore flow days.

   1. Because the mean high pressure location when delivering the air masses has been far eastern Canada, so we’re getting very modified maritime polar air that has travelled over ocean water that is warmer than average this season. It would be a different story if the mean location of high pressure for delivery was in the Upper Great Lakes. That would be giving us frequent refreshing air masses. Just not the way the pattern set-up this time.

      1. Agreed !

10. I think age doesn’t help with humidity. I never used to feel sick and we never had AC. But now ion does make me feel yuk after a while.

    For earthquakes, I have not heard NC mentioned so read. As I said above, most are in mountains and most very mild. This was large for NC. There are Faults but they are old and none are active. I’ll give Macs cousins a call later. They are in Charlotte

    This is a good read if interested

    1. For me, personally, heat started getting to me as soon as I hit my 20’s. Go figure.

11. We will have at least 3 days (minimum) of 90’s this upcoming week and as many as five. It seems the summer polar air has been bottled up in Canada since the season began. Even since late May?

    Is there a persistent SE ridge much like what happens in winter?

    1. I don’t think it’s been the SE Ridge.

       I think a mostly zonal pattern, with the jet stream along the us/Canadian border, which is a consistently above average warm, but not baking hot pattern. Occasional dips in the Great Lakes have helped to increase the humidity in waves in the northeast.

12. Couple tornadoes on this day in weather history including one in Wallingford, CT.
    https://twitter.com/NWSBoston/status/1292445528811139072

13. Lots of cumulus here in JP and with some vertical growth on
    a percentage of them. Will a shower/storm pop? Perhaps as there are some pop corn type convection here and there.

    1. Pretty nice cell down by Brockton, although my lightning app
       does not show any lightning with it.

14. Thanks, TK…

    1.01″ here in the rain gauge in the last 31 days (July 10-August 9)

    1. I am at 2.11 inch since July 1st.

15. JJ you posted the tweet about tornadoes on this date.

    Well, one of the ones mentioned was Brookline, MA August 9, 1972. I witnessed that tornado with my own eyes!
    Amazing sight to see, I have to tell you.

    Here is a write up about that storm by Meteorologist
    Michael J. Kraus. I worked with him and I have actually
    operated the dopplar radar equipment mentioned in
    this paper. (Not on this date as I hadn’t worked there in 2 years)

    Here is a link to the paper.

16. About ready to hit 90 again.

    My conservative thermometer sensor seems to be running a couple of degrees too high in the last couple of weeks.

    The radiation shield is mounted on the deck facing my side lot which is burnt to a crisp. I was wondering if the lack of green grass and the rock-hard soil is radiating heat and making the sensor warmer than the actual temperature.

    1. It has hit 90 here in JP and at Logan, Norwood, Bedford and Lowell.

17. The isolated showers are popping as expected. So far none of these have grown enough to produce any lightning, and it will be a struggle for them to do so, but I can’t rule it out. it’s especially important to know that it is possible since it is a weekend and more people are outside. The lightning threat is very minimal, but “non-zero” (I have an absolute love-hate relationship with that expression).

18. Mark posted a report on Friday that Isaías spun the first Connecticut tornado to occur during a New England tropical storm.

    I did some quick research using the Tornado History Project and a Wikipedia (the font of all truth!!! 🙂 ) article about landfalling New England tropical storms and found:
    For Massachusetts:

    An F1 tornado in Worcester and Middlesex counties and the town of Princeton in an outer band of Tropical Storm Allison, June 17, 2001.

    An F1 tornado in Holliston MA (Middlesex County) during Hurricane Gloria, September 27, 1985.

    I think that’s it for Massachusetts.

    None for Rhode Island.

    Feel free to add to the list if missed any!

    1. Don’t know if it ever touched down, but I personally witness a funnel cloud pass right past north campus of ULowell during Bob in 1991. It was documented in the Lowell Sun article written about myself and the other student who manned the lab with me all day.

19. The highest temp at Logan from what I can tell was 89. Did it get to 90?

    It has now dropped there to 81.

    Day #1 of a heat wave? Or wait until tomorrow?

    1. According to MesoWest data , it hit 90, however, there can
       be rounding issues with that, so it is possible that 89 was the high so far today.

       MesoWest says Logan is 91 now, so that seals it! It HAS reached 90.

       Here is the 2PM (1:54) Logan Obs with an EAST wind. Gee there’s a surprise!!!

       1. Thanks JPD.

          Day #1 of a 4-5 day heat wave. Today was the only uncertainty. The rest of the week is assured.

          1. Actually none of those days are really certainties for Logan. While not highly likely, both Monday & Tuesday can fall short if we have a good enough sea breeze cell set up. Wednesday is more likely as I think we’ll have a bit more gradient southwest wind there.

20. Bruins lose yet again.

21. TK, you have MAIL.

22. What minimal pop-up shower activity there was out there, has now appeared to have gone poof!

       https://forecast.weather.gov/wwamap/wwatxtget.php?cwa=box&wwa=heat%20advisory

    2. Or until further notice… 🙁

25. It’s not out the question that today can end up having been warmer at Logan than either or both Monday & Tuesday can be. The gradient will be weak enough that a sea breeze can occur, and if the sea breeze cell is strong enough, it can prevent at 90. It’s not likely, but it’s possible.

    I think Wednesday’s wind (based on current ideas) will be a bit stronger southwest and should prevent a sea breeze. But the next 2 days are not guaranteed 90+ at the airport.

26. Who said the tropics were quiet? Three active storms in the Western Pacific and another one in the Eastern Pacific. Plus, there are 2 suspect areas in the Eastern Pacific and another in the Atlantic.

    Right on schedule.

    1. The Atlantic wave has a 40-60% chance of development according to the NHC.

    2. I remember back in the “Colonial House office” days that we’d be monitoring the tropics, everything quiet, and suddenly seemingly overnight they would come to life just like that. And then looking at the big array of difax satellite pictures hanging up behind Mike P.’s desk to trace the development. Fun stuff.

27. Classic Boston Harbor downpour in progress. Localized collision of boundaries is responsible.

    We see stuff like that happen on Long Island, although more frequently.

    1. My son was returning from George’s Island and got caught in that. It was hailing and he sent me a video to prove it.

       1. Here is shot of rainbow he caught.

          https://imgur.com/a/i1QownB

          1. I buy it. It had a very brief hail signature, and very brief rotation.

28. Agree, TK. We haven’t had extreme heat. And, it’s not 2018 or 1983. It’s been a steady diet of warm to hot and quite humid. Not an all out blitz.

    I drove through a pop-up shower south of Foxboro today. It rained fairly hard for about 3 minutes.

    Speaking of earthquakes and natural disasters, who remembers the April Fool’s prank about Blue Hill erupting.

    On April 1, 1980, folks in Canton and Milton had settled down after a long day to watch the 6 o’clock news on channel 7. At the very end of the newscast an art-card flashed on the screen proclaiming a “News Bulletin.” People took notice of bulletins; after all, it was rare to break into a newscast. In what has been described as “shock and awe,” images of Great Blue Hill flashed onto the screen having been superimposed with flames and lava. Films of the recently active Mount St. Helens volcano in Washington state were used, dubbed with audio that was apparently warnings from President Carter proclaiming his “concern” and Governor King calling the situation “serious.”
    John Henning and Mary Richardson introduced the now infamous Blue Hill volcano segment but were unaware of the graphic nature of the prank.

    This prank had a further scent of authenticity when the report suggested that the eruption was triggered by the recent eruption of Mount St. Helens. The report touted “geological disturbances across the country, including tidal waves in the Great Lakes and erupting volcanoes in Massachusetts.” The reporter, Jan Harrison, gave the story such a ring of authenticity that before her report could end, the damage was underway.

    The civil defense system received urgent phone calls. The phones at the State Police barracks in Milton at the foot of the “eruption” rang off the hook with panicked inquiries. More than 300 calls were logged in, and in one case a man, believing his house was about to be engulfed by lava, had carried his sick wife outside to escape the certain destruction. Because people had panicked so early in the report, they failed to see the crudely drawn sign held up at the end of the segment, which read “April Fool.”

    1. Ha. I do not recall. That is quite funny…although maybe didn’t seem so at the time. I know Mt St Helens was in may and cannot recall but assume she started to “act out” before that. I’m assuming someone(s) got a time out.

29. Hartford’s 2020 (so far) precipitation deficit is nearly 9 inches. Generally 4-7 inches for the deficit over the remainder of SNE.

30. New weather post is up…
