Wednesday Forecast

48 Comments

7:32AM

DAYS 1-5 (MAY 10-14)
Upper level low pressure continues to spin over the region but starts to elongate and eventually slips off to the east through Friday. Another upper low and associated surface system will impact the weather this weekend. There is some question as to how far north the resulting storm will come and that will determine timing, duration, and magnitude of rainfall, something to fine-tune in the next 2 days.
TODAY: Partly sunny to mostly cloudy. Isolated showers mainly afternoon. Highs 56-63. Wind N 5-15 MPH.
TONIGHT: Variably cloudy. Lows 39-45. Wind N 5-15 MPH.
THURSDAY: Mostly cloudy. Isolated showers possible. Highs 56-63. Wind N to NE 5-15 MPH.
FRIDAY: Variably cloudy. Isolated to scattered showers mainly AM. Lows 40-47. Highs 56-63.
SATURDAY: AM sun, PM clouds, chance of rain late. Lows 42-49. Highs 56-63.
SUNDAY – MOTHERS DAY: Cloudy. Rain likely. Lows 38-45. Highs 45-52.

DAYS 6-10 (MAY 15-19)
Lingering cool air and a risk of showers May 15 as upper level low pressure hangs on, then a transition to warmer and mainly dry weather follows as the pattern becomes more progressive.

DAYS 11-15 (MAY 20-24)
Starting out dry and seasonable to warm, then wet weather returning later in the period.

    1. Hehe – now you posted three times and I agree. We are triply fortunate to have TK, his expertise and this blog……as well as all the WHW family.

  4. Thank you, TK!

    So Saturday AM looks as if it is the window to go to a nursery and start picking flowers for planters and the yard!

      1. I wasn’t referring to the here and now.

        Just more Upper lows and clouds and Rain on the horizon.

  6. It is now May 10th and the water temperature off our coast is still in the Brutal category.

    The latest from Boston Buoy, 16 NM due East of Boston:

    Water Temperature (WTMP): 48.2 °F

      1. Interesting.

        For completeness that Boston Buoy posted there is not Station 44013 (LLNR 420) – BOSTON 16 NM East of Boston, MA

        It is buoy Station BHBM3 – 8443970 – Boston, MA located well within Boston Harbor.

        But, Boston Buoy could be an outlier as well.

        We have to go by something. 😀

  7. I must say that the SKY today is as BLUE as I have seen it in a while.
    Very nice inded.

    1. We must be playing opposite day. I have a fair amount of puffy white clouds with more dark clouds. 🙂

  8. A little chilly, but overall not too bad out there today. Looking like a real soaker on the way for the weekend. Overall, I agree with TK’s forecast. I’ve been eyeing around 5/20 for a pattern change to warmer, and it looks like we’ll get some warmth by later next week. I’m not sure, though, whether it’s a short term change or if it will represent the beginning of more sustained summer-like warmth. We may just end up in a more consistently progressive pattern, with much faster weather transitions than we’ve been seeing lately.

  9. I also wanted to link the spring edition of the “Prevailing Winds” newsletter from NWS Taunton that just came out last night. Always lots of interesting stuff in there. Among other topics, this edition has write-ups on the Conway tornado and the surprise freezing rain event on 2/8. Also, changes to the Heat Advisory criteria, which will likely lead to more such advisories in the future.

    I made it into this edition as well, page 13, talking about my internship experience last summer and the project I was working on. I’ll be starting up on my new project at the office in just a few weeks… Looking forward to that, and to getting my final exams over with early next week!

    2. Nice article Jon! I will have to look out for future editions of that newsletter from the NWS. Never seen it before. Lots of interesting stuff in there.

  12. Thank you TK. Hope we see the sun a little bit on Saturday since I will be on the Vineyard all weekend. I can deal with one rainy day but not two!

  13. Both the 12Z GFS and 12Z EURO are advertising “around” 2 inches of RAIN overnight Saturday into Sunday. YUCK.

    1. At least you were forewarned months in advance about the wet May 2017. 😉

      Actually this system is looking more and more progressive to me even though it cuts off. Kind of a progressive cut-off.

      1. Yup and I see it is kind of moving.

        We have dinner reservations at 4:30 on Sunday.
        Would be nice if the rain stops by then. Looks like a chance. 😀

  16. 18Z NAM would keep it dry here on Saturday until at least 8PM, if not later than that.

  18. What a juiced up noreaster for the weekend. GFS drops 2-3″ of rain across CT with a perfect track to our south and east, and the NAM looks loaded as well. We’d be talking 20-30″ of snow if this occurred a few months ago! It does indeed look more progressive with an early Sat PM start in CT and the rain out of here by Sun PM. Start and end times a few hours later across eastern MA.

  20. I heard about this earlier today. What a sad story.
    An indication by the GFS that it will turn warmer the past two runs showing enough instability for thunderstorms next Thursday past couple of runs.

  22. New England at its best. Tom’s 10 day 🙂 🙂 🙂
