DAYS 1-5 (AUGUST 30 – SEPTEMBER 3)

It’s Labor Day Weekend, and 2/3 of it occur in August, a month that has had a theme of coolish and dry weather, and this weekend will continue that. While high pressure over the Great Lakes slowly builds eastward toward and into New England during the next 3 days, we will start out with upper level low pressure over our region, which will gradually shift eastward and lose influence. The presence of the upper low represents chilly air aloft that will trigger the development of diurnal cumulus clouds each of these days, most prolific today with a trend for fewer Sunday and fewer still Monday. Additionally, a trough swinging around the upper low will drive some additional cloudiness into our region this evening, but without any rain… All things considered, this will be a pretty nice holiday weekend with slightly below normal temperatures (coolest today, mildest Monday), no rainfall, and comfortably low humidity levels. High pressure will drift offshore Tuesday and Wednesday with continued fair weather, along with a warming trend.

TODAY: Sunny start, then a sun/cloud mix with a trend toward more clouds. Highs 69-76. Wind NW 5-15 MPH.

TONIGHT: Lots of clouds evening. Decreasing clouds overnight. Fog patches interior low elevations overnight. Lows 51-58. Wind NW up to 10 MPH becoming variable under 10 MPH overnight.

SUNDAY: Sunny start, then partly cloudy late morning on. Highs 70-77. Wind N up to 10 MPH with coastal sea breezes developing.

SUNDAY NIGHT: Mostly clear. Patchy low elevation fog. Lows 51-58. Wind variable under 10 MPH.

MONDAY (LABOR DAY): Mostly sunny to partly cloudy. Highs 72-79. Wind variable up to 10 MPH.

MONDAY NIGHT: Mostly clear. Patchy fog in low elevation areas. Lows 52-59. Wind W up to 10 MPH.

TUESDAY: Mostly sunny. Highs 73-80. Wind SW up to 10 MPH.

TUESDAY NIGHT: Mostly clear. Patchy fog in low elevation areas. Lows 53-60. Wind SW under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 74-81. Wind SW up to 10 MPH.

DAYS 6-10 (SEPTEMBER 4-8)

A southerly air flow develops September 4 & 5 with fair weather to start, but followed by a decent chance for showers with a combination of moisture from the south and a frontal system from the west. Expectations are for this to move beyond the region but another upper low to cross the area during the September 6-7 weekend with cooler, dry weather, but not completely sunny either day. High pressure builds in with dry, bright weather September 8, based on current expecting timing of systems.

DAYS 11-15 (SEPTEMBER 9-13)

A mid period interlude of more moist southerly air flow and shower chances in an otherwise mostly dry pattern with temperatures near to slightly below normal.

  2. On track to be Boston’s coolest August in 17 years – in fact it’s pretty much a lock given the confidence of the temp forecast for today and tomorrow. They’ll end up between -2.0F and -2.5F for the month. Providence is at a -3.1F and will subtract a few more tenths through tomorrow.

    In case you were wondering: Hartford: -2.6F and Worcester -1.1F with 2 data days left.

  9. It is nice to be getting a break from the humidity for most of August. It is starting to look like a front loaded summer with the worst of the heat end of June and more humid than hot weather with many days having dew points 70 or higher late June and July.

    1. I think Boston’s dewpoint went to 70 or above on only one day in August, and they only had 3 nights with a low of 70+.

  10. Watching TV, fire pit, coffee and a blanket. Can’t get much better than that for August 30th.

    My son even said “Baba, what a weird month. Isn’t it supposed to be very warm”.

  13. I was busy doing some cleaning yesterday so couldn’t post. We didn’t get much of a storm. Sky wasn’t impressive – just cloudy. We did have a lot of thunder that seemed to come more out of the south and east of us and we did get a brief downpour and a few gusts of wind. Not as impressive as a lot of others got.

  14. Thanks, TK!

    0.88” yesterday! Lawn is starting to come back!

    To those who have time off, a happy Labor Day weekend!

  18. Beautiful day. The sunny sky of the morning has become cloud-dotted with more numerous cumulus the further north and west you go. As I noted, there will be a tendency for more clouds as we head toward and into evening as the core of the cold upper low swings closest to our region. The air will be too dry though to support any showers (which have been in NNE) making it this far south.

  21. I had a 7 year memory in Facebook today, us camping in Nickerson state park down on cape cod.

    And it was blazing hot, so I checked back and Logan was 90, 97, 98 and 92 the last week of August.

    On the 29th, the low was 81F.

    No electric at Nickerson, we sweltered.

    Only makes this now 2 week stretch even more impressive to me.

  23. Though there have been cuts to NOAA, and emergency response, and it took his state to get rocked by another event, Senator Cruz of all people has turned into an ally in terms of improving the forecasting and warning systems instead of just destroying it like a particular someone wants to do. https://www.commerce.senate.gov/2025/7/sens-cruz-cantwell-introduce-bill-to-modernize-weather-radio-emergency-alerts?fbclid=IwY2xjawMgkwJleHRuA2FlbQIxMABicmlkETF3SXN0T2FjUkloRmRqa1I5AR6pwfLH9foldDlOrD67ODYW2R5lpKm4C6gxHlVOuVRVqAkEjvIKCqwU6Iiwiw_aem_3tLUWqT3V-LqW8rRTRaw-Q… Viki saw your post on yesterday’s blog and there are scientists that have gotten ahold of most of the data that trump has tried to get rid of. There was a massive push to get scientific papers out prior to trump getting in and it protects the data generally when you get them into the journals. There were things put into place prior to trump getting in that went on behind the scenes under Biden’s NOAA as well. It’s not great, we shouldn’t be needing to protect science from government officials, but we are at that point in which science is being attacked by the rulers and their followers.

  24. Excellent post. Thank you Matt. God Bless the folks who are fighting for truth. I know rehiring has been approved. It had not begun last I found.

    IMO it would be fair to give the folks trying to hold it together leeway.

    Best post there is. “we shouldn’t be needing to protect science from government officials, but we are at that point in which science is being attacked by the rulers and their followers.”
