DAYS 1-5 (MAY 1-5)

On this first day of May we find ourselves still under some influence of low pressure which continues to move away from the region via the Maritime Provinces of Canada. One more lobe of energy had to come around the back side of it last night, producing rainfall for a few hours, and maybe even some snow mixed in at higher elevations (though I have not seen any reports of this as of yet). Some cloudiness and even a few sprinkles have been around eastern areas early this morning but that is all on its way out now. There may be a few pop up cumulus due to land heating and chilly air above, but as the day goes on any of these that should pop up will dissipate as it warms aloft. But this warming aloft will bring in patches of higher cloudiness from the west, and they may dominate the sky by tonight. This will be that frontal boundary that we’ve all become well-acquainted with (and some of us rather annoyed with) coming back as a warm front. But you may feel a little better about what that boundary does for your Sunday weather. While there may still be a fair amount of cloudiness around at times, it turns into a much milder day for a good portion of the region as a southwesterly air flow gets established, however briefly. As always, a few coastal areas where a southwest wind comes across ocean water first will be cooler. Don’t get used to that warm-up because “the boundary” slips back to the south again by Monday, and a day that had “80” on it in forecast icons too far in advance to be that accurately specific, it’s going to be up to and more than 20 degrees cooler than that in some locations, and certainly significantly cooler than Sunday will be. Also, cloudiness will re-thicken and probably lead to some rainfall at least by Monday evening. And as low pressure comes along the boundary, right now Tuesday looks like a fairly overcast, showery, and somewhat cool day, as the actual front will probably stay mostly to the south (though some uncertainty on that at this point). Are you tired of this pattern yet? Well, we’re far from done with it. Next round of unsettled weather doesn’t wait as the front stays in the region and another disturbance comes along on Wednesday.

TODAY: Early clouds eastern MA/NH/RI, sunshine & passing fair weather clouds for a while, a sunnier interlude, then partly cloudy again later day. Highs 57-64. Wind NW 10-20 MPH gusting up to 30 MPH in the morning, shifting to W diminishing to 5-15 MPH gusting up to 20 MPH afternoon.

TONIGHT: Variably cloudy. Lows 45-52. Wind W to SW 5-15 MPH

SUNDAY: Variably cloudy. Highs 66-73, except 58-65 in some coastal areas. Wind SW 5-15 MPH, gusting 20-25 MPH

SUNDAY NIGHT: Variably cloudy. Lows 47-54. Wind shifting to N 5-15 MPH.

MONDAY: Mostly cloudy. Chance of light rain by late-day favoring areas south and west of Boston. Highs 55-62 southern NH and northeastern MA, 63-70 elsewhere. Wind shifting to E 5-15 MPH.

MONDAY NIGHT: Mostly cloudy. Periods of rain. Patches of fog. Lows 48-55. Wind E 5-15 MPH.

TUESDAY: Mostly cloudy. Periods of rain. Areas of fog. Highs 55-62. Wind E to variable 5-15 MPH.

TUESDAY NIGHT: Mostly cloudy. Chance of rain. Areas of fog. Lows 48-55. Wind variable 5-15 MPH.

WEDNESDAY: Mostly cloudy. Chance of rain or showers. Highs 57-64. Wind variable 5-15 MPH.

DAYS 6-10 (MAY 6-10)

No big changes to the pattern. Greatest chance of direct impact from low pressure with resultant rainfall looks like it will be around mid period, but this is very low confidence.

DAYS 11-15 (MAY 11-15)

May finally transition out of this into a more distinctive high pressure / low pressure cycle with a west-to-east flow, but again very low confidence on anything out this far.

  6. Thank you, TK. Do you have your picks for the day?

    My win is obvious. Mac’s first name was Charles and as everyone knows we were married Dec 9. So #9 Hot Rod Charlie it is for the win. Gotta figure out place and show now.

    1. Awesome news re Mrs OS. And love love this song. You can’t help but smile as you listen. Thank you

        1. I did watch a handful of episodes and it is good.

          I was just in the mood for the NFL Draft, Red Sox and Celtics last night. 🙂 🙂 🙂

  10. 4 Keepmeinmind
    9 Hot Rod Charlie
    19 Soup and Sandwich

    Those are my top 3. Not sure what order yet. Gut feeling is 9, 19, 4 for 1st, 2nd, 3rd…

    Keep an eye on..
    17 Highly Motivated
    15 Rock Your World

    1. I like rock your world and known agenda also

      19 is interesting. I don’t recall seeing a lot of greys in the derby. And 19 is another favorite number. My method of picking horses is similar to my method of picking everything else as you can see.

  12. Thanks TK!

    I keep asking what happened to spring? Then I remembered that it’s “New England”. The only region where spring “starts and stops”. 😉

    And yet, in fall it’s where summer never wants to end. Go figure. 🙂

    1. Always been this way. Location, location, location. 🙂

      A friend of mine on social media posted about being very chilly at their child’s soccer game and I remember those days very well. It was almost always colder during the spring games than the fall ones. There were very few exceptions, maybe some of the end-of-season games would go the opposite way.

      1. Chilly and rainy. We have a ton of photos somewhere of Mac holding Kim’s very wet large pony while we tried to dry Kim off.

  13. Just curious. Did anyone here at WHW from the distant interior locations of MA see any snowflakes mix with the rain overnight?

      1. Killington still with 10 trails open but down to just the superstar lift now. They will be open weekends only moving forward and should be skiing the superstar trail for at least a few more weeks. The goal each year is Memorial Day and June 1 if possible.

        Jay Peak made it to May as well but today is their last day.

      2. Killington makes it into May many years. Over the last 2 decades their average “last ski” date is about May 25.

        1. I’ve said many times. Massachusetts weekend on Tuckerman was always Memorial Day weekend
