DAYS 1-6 (MAY 26-31)

A one-day shot of heat and higher humidity today as high pressure sits offshore and a cold front approaches from the west. The timing of this front and its associated moisture means the shower and thunderstorm threat from it will hold off until about 6 p.m. or later for the region. The greatest threat for storms both in coverage and intensity, as far as the WHW forecast area goes, will be southwestern and south central NH and north central MA, or areas that have little or no stabilizing influence from a southwest wind, which at this time of year is passing over relatively cool ocean water on its way into New England. This tends to stabilize the air and make it more difficult to develop storms, or to sustain storms that already exist and are moving into these areas. Where the storms do occur, there is a threat of damaging wind gusts, which includes a very small risk of a small tornado should any of the storms be isolated and take on super cell characteristics. Again, this is a low, but not zero, probability so we should pay attention. Otherwise, the typical threats of brief heavy rain, possible small hail, and lightning will be present with any storms. Again, not a widespread event by any stretch, as most people will see activity far less than the maximum potential. Once we are by this threat, another high pressure area moves in for a nice Thursday, warm but dry. As high pressure builds across eastern Canada Friday, a low pressure disturbance will make a run at New England, the brunt of it passing south of the region Friday night and early Saturday, but close enough to put some rainfall into the region at least for several hours. The high to the north will be strong enough to push this away Saturday, which may start wet in eastern and southern areas but will dry out, and be quite cool. Sunday looks dry with only a tiny bit of temperature moderation as a general easterly air flow will continue off the still-cool Atlantic waters. Since this is also the long Memorial Day Weekend, we’ll look at Monday in this section, and it looks like the high pressure area will continue to hold with fair weather, but the center of the high may slip east enough for a more southerly air flow which will allow a bit more warming.

TODAY: Partly cloudy early, then mostly sunny before clouds return late, however clouds may dominate much of the day along the South Coast. Highs ranging widely from 65-72 South Coast with coolest Cape Cod area to 85-92 most areas with a sharp gradient in between these zones. Dew point rising to the middle 60s. Wind SW 10-20 MPH, higher gusts possible.

TONIGHT: Mostly cloudy with a fair to good chance of showers and thunderstorms north and west of Boston early through mid evening and a fair to slight chance of showers and possibly a thunderstorm Boston southward mid to late evening. Clearing overnight. Lows 52-59. Humid evening, drying overnight with dew point falling from the 60s to the 40s. Wind SW 5-15 MPH shifting to NW but may be variable with locally moderate to strong gusts around any showers/storms.

THURSDAY: Mostly sunny. Highs 77-84. Wind NW 5-15 MPH.

THURSDAY NIGHT: Mostly clear. Lows 51-58. Wind N under 10 MPH.

FRIDAY: Increasing clouds. Chance of rain by late in the day. Highs 62-69. Wind NE up to 10 MPH.

FRIDAY NIGHT: Cloudy. Periods of rain. Lows 48-55. Wind E 5-15 MPH.

SATURDAY: Cloudy with a chance of rain or drizzle to start, then a sun/cloud mix. Highs 55-62. Wind NE 10-20 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 47-54. Wind NE 5-15 MPH.

SUNDAY: Partly cloudy. Highs 60-67, coolest coast. Wind E 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 46-53. Wind SE up to 10 MPH.

MONDAY (MEMORIAL DAY): Mostly sunny. Highs 68-75. Wind S 5-15 MPH.

DAYS 7-10 (JUNE 1-4)

The first few days of June are expected to feature seasonable warmth and slightly higher humidity as a couple disturbances move through the region, but with limited chances for showers and a few thunderstorms. This may be followed by a shot of cooler air from Canada at the end of the period but I’ve low confidence on the timing.

DAYS 11-15 (JUNE 5-9)

Warmer air may try to come back early in the period with a shower threat. After that we may be near the border of air masses with additional shower threats but no signs of any widespread beneficial rainfall at this time, and no extreme temperatures.

  2. So far, dps holding in the reasonable zone. I suspect they
    will be on the increase as the day wears on. Currently dp 57 at Logan.

  6. JPD. Thinking of you and Mrs OS today.

    Jean, looks as if you will be home before any weather hits

    1. Tank you, House is very cool after windows being open all night.
      Hopefully, it won’t be too bad.

    2. Thank you, TK!

      I’m very happy to see the later arrival time for that front — now I’m hoping for some real rain from it!

      JPD, I’m rooting for minimal side effects and great peace of mind for your wife today. Please give her my best regards and remind her to hydrate extra well over the next couple of days!

  13. Syracuse, Fulton and Rome, NY are 80F to 84F at 10am and seeing plenty of sun.

    General area to keep an eye on into early/mid afternoon.

  15. Continuing eastward from west central NY state, Burlington VT is 79F and Concord, Manchester and Nashua are 80F or a bit higher at 10am.

    So, one can kind of see where the best available warmth will be.

  16. Logan is up to 82 with dp 63.
    Wind has far more Westerly component than I thought it would.
    Bummer. Logan reporting WSW wind at 13 mph.

    I do not like the WSW wind as that would allow higher temperatures and perhaps severe weather to sneak in here.

  19. Remember that an ob is momentary. A WSW wind at ob time at Logan does not necessarily reflect the predominant wind direction.

    Let’s see how this goes, copying the NWS radar from western NY State. Liftoff ……

  25. 90 and 65 DP south Sutton. Air is thick. Amazing how different the air was first thing this am than it was yesterday am.

    1. New England Spring weather always has a bouquet of middle fingers for us. Some years more bouquets than others.

    2. Funny that the GFS which was kind of doing that yesterday has backed off now. Role reversal!

  29. This will not be a widespread severe weather event but some towns could get a nasty thunderstorm this evening.

  30. From Ryan Hanrahan

  34. Vicki it looks like the line is strengthening a tad northwest of me. Currently there is a bit of a haze and so far the most humid day of this warm weather season. Dew points here got close to 70.

    1. I see that. I’m sitting out to see if I can see approaching clouds but so far none. Lots of wind

      I noticed a haze earlier today….now also

  36. The question is will the NWS out of Albany NY extended those warnings towards me. The line is starting to light up.

    1. I wonder about that for here too. I’m just starting to see the line of clouds, lit by the setting sun, come up above the trees to my WNW

    2. They won’t extend here. It’s falling apart. I’ll be happy at this point if we get some good rain

  44. I just saw a lightning bolt in the distance when I look outside my kitchen window.

      2. Storm sort of petered out by the time it got here. Lots of lightning and rain but winds never really got going

  46. Spoke to soon. TV out again. Pounding rain and hail now with frequent cloud to ground lightning.

  47. Saw first lightning here …well Now second …but must be cloud to cloud as not showing up on lightning map

  49. Eric Carle passed away. Not many who have not been touched by his stairs and amazing colorful illustrations

        1. The eclipse occurred after moonset. My friend on the West Coast got a nice pre-dawn view. 🙂

  52. Second line of storms has formed in NW CT and is now moving towards us. Thundering again now.

    1. We continue to have some impressive cloud to cloud lightning. I suspect to,ground also but from the couch can only see he former. I do see a second line..if it holds

    2. Decent slug of rain for the past 90 minutes in Boston. Lightning, too, and rumbles of thunder in the distance. Can’t tell where it’s coming from.

      Bruins – Islanders should be fun. Islanders owned the Bruins early in the season, but that doesn’t necessarily translate to the playoffs.

  54. GFS has an awful 10 day period coming up. Figures just as we come out of this rotten year and things start to get back to normal.
