DAYS 1-5 (MAY 20-24)

High pressure both at the surface and aloft dominate today with fair weather. The axis of the ridge aloft is far enough west to allow a north to northwest flow of air above us, and this has been carrying some smoke across the region at high altitude as a result of some wild fires in Canada. We’ll continue to see some of this today and possibly through Friday too. A series of disturbances will also come out of Canada Friday through Sunday. Friday’s may bring a shower into areas mostly north and west of Boston by late in the day. Saturday’s brings more clouds and a better shot at showers, but still not even close to a wash-out of a day. Sunday’s will be in the form of a strong cold front, probably timed for late-day or early evening, and this will bring a better chance of showers and possible thunderstorms to the region from north to south, but again much of that day will be rain-free. Another high pressure area comes out of Canada with refreshing air Monday after a weekend that will feature noticeably higher humidity.

TODAY: Smoke-filtered sun and also some actual high clouds dimming it more at times. Highs 69-76 coast, 77-84 inland, but turning cooler at least coastal areas afternoon. Wind variable to SE 5-15 MPH.

TONIGHT: Variably cloudy including smoke aloft. Lows 55-62. Wind SE to S up to 10 MPH.

FRIDAY: Partial hazy sun with continued smoke aloft. Chance of a late-day shower mainly north central MA and southern NH. Highs 68-75 South Coast, 76-83 elsewhere. Wind S 5-15 MPH.

FRIDAY NIGHT: Variably cloudy. Possible showers. Lows 53-60. Wind variable 5-15 MPH.

SATURDAY: Variably cloudy. Possible showers. More humid with dew point approaching 60. Highs 65-72, coolest coast. Wind variable 5-15 MPH.

SATURDAY NIGHT: Mostly cloudy. Chance of showers. Areas of fog forming. Lows 55-62. Dew point middle to upper 50s. Wind variable up to 10 MPH.

SUNDAY: Partly sunny. Chance of showers and thunderstorms, especially afternoon/evening. Moderately humid with dew point lower 60s. Highs 75-82. Wind SW 5-15 MPH, higher gusts, may shift to NW late.

SUNDAY NIGHT: Clearing. Lows 48-55. Wind NW to N 10-20 MPH.

MONDAY: Sunshine and passing clouds. Highs 62-69, coolest coast. Wind N to NE 10-20 MPH, diminishing late.

DAYS 6-10 (MAY 25-29)

High pressure retreats to the south and southeast with a warm-up May 25-26 along with an increased chance of showers with warm air moving back in May 25 and a chance of shower/thunderstorms as a cold front approaches from the northwest May 26. High pressure brings dry/cooler weather May 27 then settles over the region with fair/warmer weather May 28-29.

DAYS 11-15 (MAY 30 – JUNE 3)

Low confidence forecast. High pressure may keep the region dry through May 31 followed by an increase in humidity and shower chances sometime in the first few days of June.

  2. Good morning and thank you TK.

    Another year older, eh? Happy birthday.

    Doing anything Special, like Hampton Beach?

    1. Thanks Dave! Well, today I’m working then probably not too much other than some of my favorite music & maybe I’ll take a nice walk and even finish that with an ice cream. 🙂 Hampton soon though! I have to go up before May is over!

  6. 63 here, 63 at Logan.

    Boston Buoy, 16 NM East of Boston, water temperature
    is sitting at 55 F.

    Not bad for this date, about 4.3 degrees above average. 🙂

  11. I have a story that has nothing to do with weather but everything to do with how amazing nature is.

    When I was having my morning coffee on the deck yesterday, I noticed a bird hanging on the chicken wire inside our veggie garden. It kept flapping its wings but didn’t fly. Eventually it moved a few feet. By then I wondered if it was a baby from the bluebird house right behind the garden and started to worry. The male bluebird and the juvenile from the last brood that had been helping feed the new babies were clearly stressed.

    Eventually, the baby flew to a tree nearby. My youngest got some photos. She doesn’t like the quality but I love the story they tell.

    She said the juvenile from last years brood fed the baby once as you can see. When it tried to feed it a second time, the baby wouldn’t open its mouth. The juvenile even pecked on the babies head trying to get it to take the food. It didn’t work. But the dad came along and then the baby happily accepted the food from him.

    It amazes me that not only the parents, but the older siblings help raise the new babies.

      1. Haha for sure…never miss with dad. I can’t believe the juvenile from the last brood returns to help with the hatchlings.

  16. Happy Birthday TK! 🙂

    My own birthday will be in 6 months. Time flies! It will be here before I know it.

  17. The NHC is watching an upper level feature it thinks might transition to a hybrid system north of Bermuda.

    The Bay of Campeche has a lot of thunderstorms today. See if they can persist for a bit.

      1. I’m nervous for the Elsa storm. Probably a hurricane with widespread softball size hail. 🙂 🙂 🙂 Yes, I have 2 daughters.

  19. Several models showing the potential for 90-degree temperatures across the interior on Sunday (and possibly Saturday as well). Given the fact that the models have underestimated the temperatures for the past several days, I wouldn’t be against us seeing some low 90s this weekend.

  21. 90F !!!!

    As of 3 pm !!!!

    ……… in Burlington, VT.

    Lots of Ben & Jerry´s being served up there today.

    1. They are right where we get off of 89 onto VT-100 to go to Mac’s uncles cabin just past Stowe. I love that area.

  22. In terms of the Low to the north of Bermuda, It wont be tropical but sub-tropical which are named. Does not need to be fully tropical which it wont be.

    my attention in recent days have turned to the decaying MCV in the western GOM which could develop into something. EURo has a TD hitting the Texas coast tomorrow evening.

  24. Thank you, TK.

    Hit 90F in DC today. First of MANY 90F plus days in our nation’s capital. Love the city, but dislike the weather there from May through September. Not much wind, lots of humidity, and a tremendous amount of oppressive heat. The Brits used to give diplomats stationed in DC hazard pay. This was prior to air conditioning.

  25. Thank you and Happy Birthday TK!!
    I have a question, has anyone noticed a lack of bumblebees in the area this year, or is it just me? My lilacs around my house are usually loaded with them around time of bloom along with the other flowers in my garden, but this year they are very scarce.

    1. I don’t think we have here, but I will ask my daughter who is in the garden more than I am. That would be concerning.

    2. I’ve seen quite a few in my area, so it may be a regional issue. That can happen from time to time depending on a set of specific conditions.

      1. I don’t mind bumble bees and honey bees, but I detest yellow jackets, hornets and wasps!

        1. Me too !

          In fact, I just had a long battle with one in the basement of the house. It was a huge yellow jacket, agitated. It had stealth capabilities, disappearing for minutes at a time and not buzzing.

          Finally, it lost its patience, came out and the raid for flies and bugs seemed to work. It disoriented it enough for me to squash it.

          Now my eldest daughter will return to her room in the basement. 🙂 🙂 🙂 🙂

          1. For my coop job while attending Northeastern, I worked at a weather radar site and for one summer, I had to work in an old quanset hut and there was always a yellow jacket or 2 flying around inside the place. I used to have a tape strip and whenever I found one of those suckers I would smash them with my bar hands (either a fast clap if they were in the air or a palm smash to the wall or desk etc. and stick them to the tape strip. After awhile, the tape strip began to look pretty impressive. I hated those sobs! HATED them!!!

  27. Ok well that’s good to know other people have not noticed a decrease. You maybe right TK it could be a hyper local occurrence. We need those guys around , as much as they may dive bomb us from time to time and startle the crap out of us. Our whole eco system is highly dependent on them. The bees go, we go.

    1. Totally agree!
      I like the bumble bees and honey bees. They don’t startle me and frankly, they don’t bother me at all. The only time I was ever stung by one of those was by stepping on a honey bee on the grass and clover. They generally mind their own business.

      The wasps and hornets on the other hand, we’ll you know what they’re all about.
