DAYS 1-5 (APRIL 18-22)

Upper level low pressure will cross the Northeast today into Wednesday while surface low pressure departs via eastern Canada today and high pressure builds toward the region via the Great Lakes during Wednesday. Both days will feature diurnal stratocumulus and cumulus clouds, but they will be most extensive today when there is also the chance of a few showers. High pressure slips off to the east later this week and a trough of low pressure will start to approach from the west. A surface low will travel through the Great Lakes initially on Thursday, and a warm front extending from it will try to move through our region, but may struggle to do so, and wait for another push from a second wave of low pressure into the Great Lakes later Friday or Saturday. It remains to be seen if that front will get all the way through here either, and as we enter late week, clouds will start to dominate again, and eventually there can be some light rain or drizzle too, though right now it looks more like cloudiness than much of any wet weather.

TODAY: Clouds most numerous southwestern NH and north central MA as well as Cape Cod early in the day with sun elsewhere, then lots of clouds all areas by midday on with a chance of a few passing showers, some of which can mix with graupel or sleet. Highs 56-63. Wind SW 10-20 MPH.

TONIGHT: Partly cloudy. Lows 36-43. Wind WSW 5-15 MPH.

WEDNESDAY: Mostly sunny to partly cloudy. Highs 53-60. Wind WNW 5-15 MPH, higher gusts.

WEDNESDAY NIGHT: Partly cloudy. Lows 38-45. Wind NW up to 10 MPH.

THURSDAY: Filtered sun – high clouds. Highs 58-65. Wind variable becoming S 5-15 MPH.

THURSDAY NIGHT: Mostly cloudy. Lows 50-57. Wind SW 5-15 MPH.

FRIDAY: Mostly cloudy. Highs 55-62 coast, 63-69 inland. Wind S-SE 5-15 MPH.

FRIDAY NIGHT: Mostly cloudy. Lows 50-57. Wind SE 5-15 MPH.

SATURDAY: Mostly cloudy. Highs 55-62 South Coast / Cape Cod, 62-69 elsewhere. Wind S 5-15 MPH.

DAYS 6-10 (APRIL 23-27)

Frontal boundary will still be in the region on April 23 with showers likely. Lower confidence that additional low pressure may bring additional rain to the region for a portion of early next week before a cooler and drier trend.

DAYS 11-15 (APRIL 28 – MAY 2)

The most reliable medium range guidance continues a theme of near to below normal temperatures and a couple rounds of unsettled weather for the final days of April and first couple days of May. As for details and timing – too soon to say.

  6. I like this quote from the Danish physicist Niels Bohr: “Prediction is very difficult, especially if it’s about the future.”

  10. Negative NAO and AO, positive PNA.

    Generalities : Blocky, amplified pattern, in which some sort of ridge exists somewhere towards the western US.

  12. Three years ago this area had roughly 3-4 inches of snow. Seems to be a fair number of snows in the not too distance Aprils of old

  13. Thanks TK
    Thank you Vicki and Tom for the birthday wishes. Vicki I do remember what you mentioned about it snowing three years ago. It was the second time in my life it snowed on my birthday. The other time was 1997.

    1. Other than a good old thunderstorm, I can’t think of any weather event more special for my birthday for snow

      TK…I had a thought. Can you work on that for mine this year too 😉

  14. I have never had a thunderstorm on my birthday. I have had on my birthday rain snow sunny cloudy heat but never a thunderstorm.

    1. Happy Birthday, JJ.

      Some day you’ll get a thunderstorm, maybe even thundersnow, on your birthday.

    1. I wonder if there will be anyone celebrating that special day? 🙂

      A former coworker and I used to go crazy over dates like this. The early years of the millennium were a heyday!

      1. One of my children was born on 12201991. If only he could have help out for a few more hours.

  17. Hey JJ, Happy Birthday!!
    I guess I didn’t realize that we share the same birthday, gotta love those Aries weather nuts.

  19. A few showers may mix with graupel and/or sleet this afternoon, especially inland hills.

    1. Some spotty showers here. Just dropped granddaughter at her riding lesson. No indoor. It is Raw. But then much easier than HHH

  21. Always a fun post-marathon day in Boston. In Back Bay and the Copley Square area you see so many folks who’ve run the marathon. And they’re from all over the world. They’re wearing their gear (including the medal for finishers) and sightseeing.

  24. Happy Birthday JJ!

    Note to Jimmy B. … I approved your comment from earlier that ended up with that mysterious + on your username (happened to 3 different people now) that throws it into moderation. Not sure what WP was doing with that. Bizarre site.

    Weather thoughts… Well, no real changes to the forecast I wrote. I guess the real question to answer is when the trough from the west impacts us most. Looks pretty late in the weekend / early next week in terms of rainfall threats. May see more cloudiness before that but limited or non-existent rain chances through Saturday.

  27. Thank you for the birthday wishes everyone, no worries Vicki at this point I try to forget lol .

    2. Hahaha. I did the the same for a while and think…just maybe…I’m at the point where each one is celebrated. Especially since TK promised snow for mine this year.

      I hope you have and have had a very special day

  28. What a strange but wonderful win for the Red Sox. It looks like the RF for the Twins gave up on a high fly ball by Verdugo near the Pesky pole, perhaps thinking it will go foul. Well, it didn’t. It hit the wall and rolled away from the fielder driving in the winning run.

    Another precious moment in the game was when a duck couple landed on the field. https://twitter.com/wegoticezo/status/1648475886008807429?

    1. Awwww. Mr and Mrs mallard Looking for a new home for their brood Jack, Kack, Lack, Mack, Nack, Ouack, Pack, and Quack
