DAYS 1-5 (AUGUST 15-19)
Quick update for today’s blog, just to say no major changes from what I said yesterday, other than just making a few minor tweaks. We will run relatively minor shower risks the next several days, and we may struggle to burn some of the clouds off on Friday and Saturday as marine moisture invades the lower atmosphere due to high pressure centered to the north and east of the region bringing more marine air in. By the end of this period, it will feel more like mid summer again.
Forecast details…
TODAY: Partly sunny. Areas of fog early. A brief pop-up shower possible southwestern NH afternoon. A passing shower possible outer Cape Cod / Islands too.
Highs 73-80. Wind E to SE up to 10 MPH.
TONIGHT: Partly to mostly cloudy. Areas of fog. Lows 55-62. Wind light SE.
FRIDAY: Mostly cloudy to partly sunny. Areas of fog morning. Passing light showers possible Cape Cod / Islands and a slight risk of an afternoon pop-up shower interior hills. Highs 75-82. Wind variable, mostly E to SE, up to 10 MPH.
FRIDAY NIGHT: Partly to mostly cloudy cloudy. Patchy fog. Lows 60-67. Wind light E to SE.
SATURDAY: Partly cloudy. Isolated afternoon showers and thunderstorms, favoring interior hills. More humid. Highs 78-85. Wind E to SE 5-15 MPH.
SATURDAY NIGHT: Partly cloudy. Patchy fog. Humid. Lows 62-69. Wind light S.
SUNDAY: Partly sunny. Isolated afternoon showers and thunderstorms. Humid. Highs 80-87. Wind S up to 10 MPH.
SUNDAY NIGHT: Partly cloudy. Patchy fog. Humid. Lows 62-69. Wind light S.
MONDAY: Partly cloudy. Humid. Highs 85-92. Wind SW 5-15 MPH.

DAYS 6-10 (AUGUST 20-24)
Jet stream remains weak and lifts to the north with temperatures sliding to the warmer side of normal, a some late summer heat/humidity, and limited shower/thunderstorm threats.

DAYS 11-15 (AUGUST 25-29)
Very warm and humid pattern with increasing risk for shower/thunderstorms as a weak west to east flow continues but the jet stream sinks back to the south.

  4. Good morning and thank you TK.

    Low clouds this morning with no discernible fog, however, I did notice
    some tiny droplets on the windshield from mist,drizzle,fog droplets????

    On Another subject: Observed wind speed

    When the observation locations report wind speed is it whatever the instrument is
    reading at the time of observation? OR is it an average speed over the past minute or 2?

    I have heard the term 1 minute mile to indicate the average over a 1 minute period.

    My new Davis Vantage Vue equipment gives me the current reading, but also provides
    a 2 minute average and a 10 minute average.

    Perhaps a simple little question, but I have not seen it discussed here in all the years
    the blog has been in existence.

    Thank you and all have a great day.

  5. Thank you, TK.

    Temperatures and dew points align across parts of the region … fog.

    This kind of fog is very typical, by the way, in autumn in the Netherlands. In fact, it would happen almost every day for weeks on end. Sometimes the fog would burn off during the day, but often it would not entirely. I remember riding my bike to school in the early 1980s – about a 6 mile ride each way – through fairly dense fog on a bike path through the woods and farm pastures.

  8. Right place right time to get a shot of that tornado. Your right JpDave we usually don’t see photos of tornadoes here in New England. The one tornado caught on camera that most of us might remember is the Springfield tornado when it came across the bridge there and headed into downtown Springfield.
    Is that the northern part of Maine where that tornado happened? I am asking because on Monday SREF was showing a lot tornado risk for that part of Maine and I am wondering if the SREF did a good job once again at sniffing out an area where a tornado was possible.

  11. I mentioned this as a possibility a couple weeks ago, but with the data now finalized, NOAA has confirmed that July 2019 was the hottest month on record for Earth.

    Because of the Northern Hemisphere’s large land area, which heats more than water, the planet’s warmest average temperatures occur during Northern Hemisphere summer.

        1. And I suspect that every month from now on will be the “hottest” on earth. This is just the beginning unfortunately.

          2. Keep in mind, as I mentioned, that the “hottest” months for the planet in an absolute sense are almost exclusively reserved to July and August because of the differential heating of the planet. So while we may have more hottest months (ie hottest October, December, etc.) going forward, there are really only two opportunities annually to set an absolute hottest temperature. With El Nino fading out, we may see some slight cooling of the planet, relative to recent months, over the next year or two, but it will easily remain above the long term average as the effects of the ENSO cycle are not nearly strong enough to outweigh human-induced warning.

  12. Today anyway, seems the models offer a brief break in the upcoming warm/hot pattern.

    Warm turning to hot Sunday into early next week, but appears a dip will offer a cool shot sometime next week, then as that trof lifts out, the warmth/heat returns again towards days 9 and 10.

    Today is beautiful. The sun has even appeared in easternmost Marshfield.

  13. Attitash sent out a email today about there Octoberfest. In that email they said some of the high peaks are starting to show signs of change colors. Not sure if anyone here has been up there lately????? I may have time this weekend to drive through and will snap some pictures if I see any change.

    1. My sister can confirm this. She lives up in Vermont and is an avid hiker. It’s the usual higher elevation changes, triggered in part by this past week’s relatively cool period up there. The changes are very subtle, but for a keen observer noticeable.

  14. Tom, I suspect the model runs will continue to be somewhat variable. I, for one, was and am skeptical about a prolonged stretch of 90s in late August. It has happened before, for sure, but usually this time of year it’s a bumpy ride if you will: a couple of hot days followed by a `cool’ down, and so on and so forth. I expect this to be the case this year. In fact, I wouldn’t be surprised if the jet stream that’s shifting north soon makes a couple of dips over the next 10-15 days to `cool’ things off periodically.

  16. Were on the back nine summer and to me once you get past the first week of September its tough to get sustained heat and humidity just like when the calendar turns to March its tough to get sustained cold.
