DAYS 1-5 (MAY 4-8)

Low pressure moving along a frontal boundary just to the south of New England brought in another round of rainfall overnight, which will exit today. We may see slight improvement in the weather later today in the form of breaks in the clouds as a bit of dry air tries to move in from the north, but the next low pressure is not far behind and will thicken the clouds back up tonight. This low is destined to take a track further north, passing north of the region during Wednesday while a secondary low tries to form near or just south of the region before the entire system pushes offshore at night. This will allow high pressure to build in with nice weather on Thursday after additional unsettled weather during Wednesday. I’ve been eyeing the situation for late week with the potential for impact from yet another storm system. The guidance has been fairly consistent over several runs in trending this system weaker and further southeast – something we have seen a lot of over the last couple months with guidance forecasts of a system as we get closer to it. Most of the time this has worked out and I see no reason to turn my back on it this time. So while I do think we will be somewhat unsettled again Friday, I don’t expect a significant storm system. This low will start to intensify as it pulls away Saturday, which should be a mostly dry but rather blustery and cool spring day as it stands now…

TODAY: Overcast with periods of rain and areas of fog in the morning. Cloudy with areas of drizzle and fog early-mid afternoon. Breaking clouds late afternoon. Highs 48-55. Wind NE 5-15 MPH.

TONIGHT: Mostly cloudy evening. Cloudy with numerous to widespread rain showers and a chance of thunderstorms overnight. Areas of fog overnight. Temperatures steady 48-55. Wind N 5-15 MPH early evening, variable up to 10 MPH late evening, SE 5-15 MPH overnight.

WEDNESDAY: Mainly cloudy with periodic rain showers and a slight chance of thunderstorms through early afternoon. Variably cloudy with an additional passing rain shower possible mid to late afternoon. Highs 58-65, coolest South Coast / Cape Cod. Wind S 10-20 MPH shifting to SW.

WEDNESDAY NIGHT: Clearing. Lows 41-48. Wind SW 5-15 MPH shifting to NW.

THURSDAY: Sunny to partly cloudy. Highs 61-68. Wind NW 5-15 MPH becoming variable.

THURSDAY NIGHT: Increasing clouds. Lows 43-50. Wind NE up to 10 MPH.

FRIDAY: Mostly cloudy. Light rain and areas of drizzle possible, favoring southern areas in the afternoon. Highs 51-58. Wind E 5-15 MPH.

FRIDAY NIGHT: Cloudy. Chance of rain showers. Lows 42-49. Wind NE 5-15 MPH.

SATURDAY: Partly sunny. chance of rain showers. Highs 55-62. Wind N 10-20 MPH.

DAYS 6-10 (MAY 9-13)

A small area of high pressure is expected to bring fair weather during the day May 9 before the next disturbance arrives from the west with additional rounds of unsettled weather May 10-12, before improvement later in the period. Temperatures near to below normal.

DAYS 11-15 (MAY 14-18)

Weak to moderate zonal flow with mean trough in the northeastern US seems the most likely pattern with a couple episodes of showers otherwise mostly dry weather and temperatures near to below normal.

  3. Thank you, TK.

    We had 1.04 overnight. Finally more than the 0.02’s and 0,08’s we have been getting. I sure appreciate your adding in when there is a chance of a thunderstorm overnight. 🙂

  5. If this was winter some places could of have had some decent snow. If patterns hold we could have more snow than this previous winter. Just a guess on my part.

    1. So what do you have in store for us tomorrow?
      After all, it will be Cinco De Mayo!

  7. Thanks TK!

    I heard on the local news this morning that today is “Teachers Appreciation Day”!

    To all you Teachers…

    THANK YOU!!! 🙂

      1. It’s actually the sauce that forced me to give it up years ago. I liked it but it just didn’t agree with my stomach going back to my college years. Oh well.

        1. Haven’t had McDonald’s anything in a long time since
          my wife developed allergies to the shit they put in everything!

    2. Good stuff ….. some possible titles ….

      A new block
      The gloom strikes back
      Return of the east wind
      The under 60 Menace
      Attack through the back door
      Revenge of the mist
      The chill awakens
      The last (and only) warm day
      Rise of the heating bills
      Rogue 1, a random sunny day

        2. Not too long.

          I had to call up all the titles on wikipedia and the New England April and May weather features came pretty easy.

          I figured out yesterday, usually the April and May weather doesn´t bother me as bad because I´ve been in a classroom teaching and thankful that it is cool. But, having this April and May off and actually seeing what the weather is like all day long, it really is, a cool location in spring.

          2. I think Marshfield is a cool location in any season.

            We have a friend who lives in Marshfield on Constitution Road.

  12. 48 degrees with a brisk wind at this hour.
    .80″ of rain during this last event. Nearly 2″ in the last week!

    I might consider combining Teacher Appreciation Day and Cinco de Mayo eve with a couple of Coronas tonight. We do have fajitas on the menu.

    Still doing remote/hybrid work as I have since September 15. Still no word on the date we go back fully in-person. Kids’ last day is Friday, June 18.

  13. Joshua…the woman who is helping me virtually with getting in shape was in Boston visiting this past weekend. She ran around the garden and common and said the tulips are spectacular. She said it was very crowded also and was a bit surprised at lack of masks. I am convinced our tulips and daffodils are lasting longer than usually here

    1. Yes, the flowers are lasting a long time. We haven’t had any heat. That helps.

      And yes the downtown area is very crowded. I even hear foreign languages; mostly Spanish. I assume these are tourists from South America, which is a bit concerning given the prevalence of P.1. I know they’re not from Europe as we still do now allow visitors from Europe.

      Many more people are now maskless than just a few weeks ago.

  15. Glad I stuck with the drying air and potential breaks in the clouds. Actually a good deal of sun at least for the time being near the MA/NH border. Thinning clouds, breaks, and partial sun in many other places.

      1. Clouds coming back now but they were expected to do so this evening anyway. It’s really nice outside either way. 🙂 Even our “unfair weather” days turn out to have nice parts to them. We’ve had almost no complete wash-outs in months.

        1. Still on deck. Grilled and am now simply enjoying the night. I did not start fire bowl because it’s supposed to rain so could not safely cover but don’t even need a jacket.

            2. NWS discussion mentions substantial rainfall but then later mentions .75 to 1.0 total amounts,. Should that really be considered substantial? I would think of 3 inches to be substantial.

              1. 0.75 to 1.00 inch for this area at this time of year, definitely not “substantial” by the definition most of us know. 😉
