DAYS 1-5 (AUGUST 21-25)

Upper level low pressure will hang around today then start to lift out on Thursday. This cool pool of air aloft, combined with solar heating each day, will aid in the development of clouds. These clouds can produce a few scattered showers and even thunderstorms, with the latter while still a low probability being more possible today than tomorrow. Any pop up showers or storms can produce small hail today with the magnitude of cold air aloft. Activity tomorrow should be more isolated and mainly north of Mass Pike. High pressure will bring fair weather and a warming trend Friday-Sunday. Humidity remains very low into the weekend before nudging up by Sunday.

TODAY: Sunny start, then a sun/cloud mix. Isolated to scattered showers and a slight chance of thunderstorms mainly between 1:00 p.m. and 6:00 p.m.. Showers/storms can produce briefly gusty wind and small hail. Highs 68-75. Dew point around 50. Wind NW to W up to 10 MPH.

TONIGHT: Clearing. Patchy ground fog interior lower elevation locations. Lows 50-57. Dew point near 50. Wind variable under 10 MPH.

THURSDAY: Partly sunny. A pop-up shower possible mainly north of I-90 during the afternoon. Highs 70-77. Dew point near 50. Wind variable up to 10 MPH with coastal sea breeze possible.

THURSDAY NIGHT: Partly cloudy. Patchy ground fog inland lower elevations. Lows 48-55, coolest inland lower elevations. Dew point upper 40s to 50. Wind variable under 10 MPH.

FRIDAY: Mostly sunny. Highs 73-80. Dew point lower 50s. Wind W 5-15 MPH.

FRIDAY NIGHT: Clear. Fog patches interior lower elevations. Lows 55-62. Dew point lower 50s. Wind W to SW up to 10 MPH.

SATURDAY: Sunny. Highs 79-86. Dew point middle 50s. Wind W to SW 5-15 MPH.

SATURDAY NIGHT: Clear. Lows 57-64. Dew point middle 50s.

SUNDAY: Sunny. Highs 80-87. Dew point near 60. Wind SW 5-15 MPH.

DAYS 6-10 (AUGUST 26-30)

A disturbance brings a shower and thunderstorm opportunity August 26. Upper level low pressure may produce a pop-up shower during August 27. Generally fair weather is expected after that until the very end of the period when an approaching trough / front brings a shower / t-storm opportunity. Temperatures briefly cooler, then warming back up again.

DAYS 11-15 (AUGUST 31 – SEPTEMBER 4)

Early hints on Labor Day Weekend are for fair and seasonably warm weather which may then carry through the period with high pressure to the south and weak weather systems passing mainly to the north of New England.

  1. Thanks, TK.

    Glorious stretch of weather here continues. I’ve had practically no rain. I’m so lucky. Temps during the day between 68F and 75F with nighttime lows in the low to mid 50s. Almost no humidity. Can actually go outside and do things without feeling like a zombie.

    I genuinely love it here and wish I could live here permanently.

    1. Pretty much what it’s like here right now. 🙂

      Today: Practically no rain – few pop up showers under a cool pool. 50s this morning. Highs 68-75. Dew point near 50. 🙂

  2. Either the sensor at Norwich, NY airport is malfunctioning, or there’s some strange stuff going on in central NY right now:

    KOIC 211115Z AUTO 00000KT 3/4SM -SN BKN001 OVC010 08/08 A3009 RMK AO2 T00750075

  4. Good morning and thank you TK

    Down to 56 here this morning.

    Looks like the ocean temps have started the slow decline responding to cooler temperstures and lowering sun angle.

    Boston buoy around 65 and Block Island around 70.

  10. I hope the impact on winter is for a snowy one with 2-3 6 plus snowstorms after the duds we have had the past two winters.

  11. We have not had a HOLY CRAP BATMAN from you JpDave in the past two winters. Maybe will get one this winter

  12. To follow up on a post TK made yesterday

    Temp anomolies thru 8/20

    Logan: -0.3F
    Probidence: -1.3F
    Hartford: +1.8F
    Worcester: +0.8F

    All probably likely to tick down another tenth, if not a couple tenths today and maybe Thursday, combined. That will take things to the 22nd, then we’ll see what happens.

        1. I think we’ll get the show in. I was just in contact with the pyro guys and the Hampton contact who reports to the commissioner.

          Shower threat is highest there until 5PM, which is about when the pyro company arrive. Shower threat exists until sunset but diminishes. I think with their tarp covering they can temporarily pause and cover if something else goes through. By safety-check and shoot-time we should be clear of any showers!

          Cool night ahead though!

  16. While I went by Nws sensor less than a mile from here this am, I think my weather unit stopped working. It hasn’t moved all day. Meeting tonight but will get Mr K out tomorrow ..both of them….and check to see if sensor was moved outside

  17. Dropped briefly to the lower 60s with a heavy shower that moved through in the 4PM hour…

    Some temps in Upstate NY did not escape the upper 50s today!

    1. Meh!! It’s august. It won’t last long. Would like it a bit cooler but Just one of the reprieves I’ve always loved.

  20. Washington DC’s low temp of 59 on Wednesday marked the first time in over 2 decades the temperature was below 60 there in the month of August. 8/7/2004 was the last time it went sub-60 in the month of August.

  21. Remnants of Ernesto hitting the UK in stages. The southeast – where I am – will be the least affected. But there was quite a bit of wind overnight and today, with some lashing rains. Nothing unusual. Just an Atlantic low traversing the area.

    Summer doesn’t have the kind of bounce back power it has in New England. This doesn’t mean you can’t get some relatively warm days in late August/September. But they’re infrequent and almost always below 80F.

    1. Even our summer bounceback in the current pattern is weak-ish. We recover to 80+ for a couple days this weekend before another cool-down occurs.
