DAYS 1-5 (MAY 5-9)

We’re heading back to the cooler side of normal for the next several days, and you’ll really notice it by the end of this 5-day forecast period. Of these 5 days, today is probably the nicest of them all as high pressure controls the weather. It’s a cooler Canadian high but will provide dry weather, although the day starts out breezy before winds subside. Low pressure makes a run at the region later Wednesday, passing southeast of New England with the slug of rain, most of it falling Wednesday night, though clouds hang around Thursday as that low departs and a trough approaches from the west, perhaps triggering an additional rain shower. The next low pressure area will already be on the approach Friday so don’t expect much clearing for that day either, and this system will be a bit more potent as it passes, but once again it looks like the bulk of the steadiest precipitation will occur in the nighttime hours Friday to very early Saturday. This time, enough cold air will be involved so that some mixing or even a chance to snow is possible across the interior higher elevations. As the system pulls away on Saturday it will be blustery and unseasonably chilly for May with showers of rain and even mixed rain/snow across the interior hills continuing…
TODAY: Mostly sunny. Highs 53-60. Wind N 10-20 MPH then diminishing.
TONIGHT: Partly cloudy. Lows 36-43. Wind variable up to 10 MPH.
WEDNESDAY: Increasing clouds. Highs 53-60, coolest coast. Wind variable up to 10 MPH with sea breezes.
WEDNESDAY NIGHT: Cloudy. Rain developing. Lows 42-49. Wind NE 10-20 MPH, strongest near the coast with gusts around or above 30 MPH Cape Cod.
THURSDAY: Mostly cloudy. Risk of rain showers. Highs 50-57. Wind NE 5-15 MPH early becoming variable.

THURSDAY NIGHT: Lots of clouds. A possible rain shower. Lows 37-44. Wind N 5-15 MPH.
FRIDAY: Mostly cloudy. Highs 50-57, coolest Cape Cod. Wind N 5-15 MPH.

FRIDAY NIGHT: Cloudy. Rain likely, may mix with or turn to snow across interior higher elevations of northern MA and southwestern NH. Lows 33-40. Wind NE 10-20 MPH, higher gusts especially coastal areas.

SATURDAY: Mostly cloudy. Showers of rain, possibly rain/snow mix higher elevations interior northern MA and southwestern NH. Highs 42-49. Wind NW 15-25 MPH.

DAYS 6-10 (MAY 10-14)

Fair, very cool May 10. Temperatures continue below normal overall but not quite as chilly with 1 or 2 minor systems with rain shower threats between May 11 and May 14.

DAYS 11-15 (MAY 15-19)

Temperatures trend a little closer to normal with a mid period risk of rain showers.

  4. Thank you, TK.

    Beautiful day outside. I do like this weather. It’s kind of like mid to late October. The cooler air has `refrigerated’ the flowers. They’ve stayed longer in bloom.

    My mother’s birthday is May 10th. In spite of her passing, my siblings and I will celebrate it with a Zoomtails hour on Sunday. I’m not religious, yet I find myself looking skyward occasionally during my jogs along withe Charles. “What would you have thought of all this, Mom,” I ask. “And, how do you like my face mask bandana?”

    1. This is just lovely. No mater what, I am sure your mom is smiling down with love and pride

  7. Good timing, JJ

    I was about to post about overnight, tomorrow night.

    That low isn’t too far offshore and if it can throw back some precip into interior southeast Mass tomorrow night that has some intensity, I think some rain could briefly switch over to wet snow.

  8. I forgot to mention the 12z GFS snowfall I posted was overnight Friday into Saturday morning.

  10. It’s not often were watching a snow threat in May. Will see what the rest of the 12z runs show.

    1. That will depend on mean ridge position, but that’s one valid possibility. We may end up with a ridge axis too far west to really deliver the “goods” (if you like NW flow storms) into New England, but Midwest would be more vulnerable. Will be monitoring this.

      I still feel our upcoming summer will be one much more “average” than, say, the tropical saunabath we were going through 2 years ago.

      I am, with time, becoming a little more concerned about the potential hyperactivity of the tropics as we get on into summer and autumn.

      1. hyperactivity of the tropics
        As if we need that on top of everything else. Geez, does it ever end???

        1. Well, sometimes conditions come together for above average activity. That may happen this season. But if we have the pattern I think we may have over North America, it’s going to be very difficult for a lot of those storms to get that close.

        1. Ah, but there can be perturbations in the flow that
          still could allow a system or 2 up here. If there is much activity, it will have to monitored carefully.

  12. I like the ease of the chill the EURO is projecting at days 9 and 10 of its 12z run.

    I can do 8 more days of chill and occasionally bouts of chilly rain, with interior wet snow.

  14. If you see a weird post published.. I’m just running some tests. They will be deleted at some point. Don’t bother commenting on any of them. 🙂

  15. JP Dave would probably state that it was the president talking coherently Sorry for commenting when told not to

  16. Vicky , I was just joking around . It was only based on the test post above. Sorry if it was taken differently

    1. That’s a tough one, because we can forecast what type of season we think it could be, #-wise, but to pin point one area is pretty much impossible. Statistically your odds would go up if there are more storms than average, because there are more chances than average to have something form or track nearby.

      My early feeling on this is that a lot of jet stream is going to protect the East Coast but areas to the south would have a typical to above average shot, just as a generality. We’ll have to track it storm by storm once we get into the season.
