DAYS 1-5 (APRIL 30 – MAY 4)

The story’s the same. We’ll be dealing with a frontal boundary in the area for days to some. But today as the third in a series of disturbances in this stretch moves away from the region, it’s going to be intensifying significantly, and resulting in quite a bit of wind. This air coming from the west will dry us out after yesterday’s wet weather. Yesterday’s rainfall amounts were heaviest north of I-90, but this was an area that needed it more than areas along the South Coast, so in general this was quite good. After a milder day today due to the air flow coming from land, a cold front will pass through the region this evening, shifting the wind to northwest, and a secondary trough will follow that, with a band of rain and even some snow showers as it will be getting marginally cold enough at the surface and definitely cold enough aloft to support this. No snow accumulation will occur, but technically there may be some areas that see very early May flakes with this happening after midnight. During the day Saturday it will start out quite windy and chilly with a sun/cloud but the wind will relax. But already by afternoon we’ll be seeing high and mid level clouds racing back in from the west ahead of that frontal boundary which will already be heading back in this direction as a warm front ahead of another low pressure disturbance. This races by Saturday night and pulls the front back south again, maybe with a few showers around, but not cold enough air for any mix/snow this time, and then the front sits right in the area Sunday into early next week, with the last few days of this forecast carrying a fair amount of uncertainty, dependent on the position of the boundary and the timing of disturbances moving along it…

TODAY: Variably cloudy. A passing rain shower possible. Highs 58-65. Wind W increasing to 10-20 MPH but gusting 30-40 MPH at times by afternoon.

TONIGHT: Variably cloudy. A passing rain or snow shower possible overnight. Lows 35-42. Wind NW 15-25 MPH, gusts 35-55 MPH, strongest in highest elevations.

SATURDAY: Partly sunny. Highs 55-62. Wind NW 10-20 MPH, diminishing and shifting to W.

SATURDAY NIGHT: Mostly cloudy. Light rain possible overnight. Lows 44-51. Wind variable 5-15 MPH.

SUNDAY: Mostly cloudy. Slight chance of rain. Highs 57-64. Wind variable 5-15 MPH.

SUNDAY NIGHT: Variably cloudy. Slight chance of rain. Lows 47-54. Wind variable to W 5-15 MPH.

MONDAY: Variably cloudy. Highs 55-62 southern NH and northeastern MA, 63-70 elsewhere. Wind variable 5-15 MPH.

MONDAY NIGHT: Variably cloudy. Chance of rain showers. Lows 48-55. Wind variable 5-15 MPH.

TUESDAY: Mostly cloudy. Chance of rain. Highs 55-62. Wind variable 5-15 MPH.

DAYS 6-10 (MAY 5-9)

For now it looks like a similar pattern with a boundary hanging in the New England area, variable temperatures and episodes of unsettled weather but not possible to time individual rain threats and specific milder or cooler days.

DAYS 11-15 (MAY 10-14)

Overall pattern similar to start then may break down into a more conventional west-to-east moving weather pattern with time.

  4. Thank you, TK. My grandkids have rediscovered their yo-yo’s. I enjoy practicing the tricks I perfected as a child. Your forecast sure reminds me of those.

      1. It was a handful of flakes. We have quite dark clouds overhead and a really strong, cold wind. No idea

      2. Nope. My turn to say I am wrong. It was flowers from the neighborhood flowering pear trees. So sad.

  7. Thanks TK, you’ve had some great discussions lately in what’s been a very challenging period of forecasting 🙂

    Several days ago I mentioned this could be an “interesting” week in the region. I think that highly specific prediction has verified well enough, including what will be a fairly significant wind event over the next 24 hours. Glad to see SNE got some beneficial rain also. Obviously still not a drought buster, but enough to continue keeping any serious concerns on the backburner.

    For what it’s worth, the pattern next week looks a bit interesting also 😉

  8. Mild air now from land breeze, 57-64 across a lot of the area. The cold air won’t be here for about 10 hours. But we’ll know when it arrives.

  9. Wind just picked up in Reading.
    Can tree bud debris be counted as a type of precip? It’s “raining” tree buds with every gust!

  11. Thank you, TK.

    Some accumulating mountain snow on the way – above 3,500 feet – across much of Northern New England.

  12. Vicki, the petals from the cherry blossoms and other trees that are past peak bloom really do look like snow. On my run I saw the petals coming down and then blown around by the wind. Looked like snow.

  13. I wonder if any hype-masters without met degrees got a hold of today’s 00z CFS super long range run that drove enough cold air behind a departing low to produce snow almost all the way to the NH/MA border .. on May 24. 😉

  14. I’m sitting out. The roar of the wind through trees surrounding the neighborhood is awesome. We are gusting into low 40s

  15. Has this been an unusual year for wind? I don’t remember a calm day yet. Hope you all are safe and healthy.

    1. Sure has been. I think the last couple of years also.

      Always nice to see you here. I hope you and your family are well also

    3. Not really. It’s just a windy pattern. We had been in a “less windy that normal” pattern for a while before that.

      Pete’s explanation on air (and Twitter) was good. And sometimes we get clusters of similar events. It’s just the pattern.
