DAYS 1-5 (SEPTEMBER 13-17)

Happy Friday the 13th! If you used today as a day to extend your weekend or otherwise have the day off from your usual daily toil, it’s your lucky day! We’re going to see plenty of sun and temperatures that climb enough to give the feel of mid summer for several hours. As a cold front approaches from the north late in the day, some clouds will start to develop, and a couple of them can build enough to produce a spot shower or thunderstorm mainly in southern NH and far northern MA by the end of the day, but this chance is low and any activity would be isolated with the extreme majority of our region seeing none of that. Any that do pop up will fade this evening and the frontal boundary will continue southward through our region with just some clouds. Another thing you’ll notice today is the hazy look to the sky and filtered nature of the sunshine, and this is once again due to a plume of wildfire smoke from both Canada and the western US as fire season goes on. Overnight, some foggy areas can develop as the temperature drops to meet a dew point that did rise a little bit off recent much lower values. You may notice that today, if you’re sensitive to humidity, that the dew point has climbed to around 60. High pressure will continue to be the mainly player in our weather this weekend and early next week as well. While the weekend will be slightly cooler than today will be, especially along the coast with an easterly component to the wind due to the high to the north, we will continue to see temperatures running above normal, and this warmer spell will also continue into the beginning of next week.

TODAY: Some cloudiness around eastern MA and RI during early morning, otherwise sunshine filtered by high and mid level wildfire smoke. Additional clouds pop up later with a slight chance of a shower or thunderstorm across southern NH and far northern MA by late afternoon. Highs 80-87. Dew point heads to near 60. Wind S up to 10 MPH.

TONIGHT: Some clouds early then clearing, but patchy fog forming later. Lows 56-62. Wind W up to 10 MPH.

SATURDAY: Mostly sunny. Highs 75-82, coolest coast. Wind N to E up to 10 MPH.

SATURDAY NIGHT: Mostly clear. Patchy fog interior lower elevations. Lows 51-58. Wind variable under 10 MPH.

SUNDAY: Mostly sunny. Highs 75-82, coolest coast. Wind variable to E up to 10 MPH.

SUNDAY NIGHT: Mostly clear. Patchy fog interior lower elevations. Lows 51-58. Wind variable under 10 MPH.

MONDAY: Mostly sunny. Highs 76-83. Wind variable up to 10 MPH.

MONDAY NIGHT: Mostly clear. Patchy fog interior lower elevations. Lows 52-59. Wind variable under 10 MPH.

TUESDAY: Mostly sunny. Highs 77-84. Wind SW up to 10 MPH.

DAYS 6-10 (SEPTEMBER 18-22)

On the larger scale, we don’t completely lose the blocking pattern we have, but it can adjust enough to allow some of the moisture held to our south to make its way to north, to introduce higher humidity and a shower chance by the middle of next week. Some guidance shows this while other guidance does not, but the possibility is there, so for now it’ll be part of the outlook. Later next week the indications are for another stronger push of high pressure from eastern Canada and dry weather and a slight cool-down. Monitoring the trends and eventually will be able to provide more detail. One thing we know for sure: Autumnal equinox is 8:43 a.m. September 22.

DAYS 11-15 (SEPTEMBER 23-27)

The general trend is for high pressure to be in control most of the time with a dry and fairly mild pattern (though a push of cooler Canadian air is possible for a portion of the period).

  5. Northwestern Europe is experiencing very different weather compared to the Northeastern U.S. Lots of periodic (heavy) rain there, followed by brief dry and chilly spells with ground frost reported early this morning across the interior of the Netherlands, for example. The first reports of ground frost are typically in late September/October in the Netherlands. So it’s rather early for coldish early mornings.

    1. Part of this pattern is actually quite normal. As I’ve said many times before, autumn in Europe is VERY different from here. In fall, Europe is more prone to storminess, heavy rainfall and general tumult in the weather department than we are. The reverse tends to be true in spring when we are at our most volatile and most of Europe tends to be rather tranquil. Of course, what I’m saying here is a generalization. Exceptions do happen. But it’s definitely been my experience, having lived in both places for decades.

  12. Was out watering the shrubs and the wind BLASTED IN FROM THE EAST. It wasn’t cold, but was noticeable. 🙂

  13. As I see it now we have about a 48 hour (or so) window the middle of next week to get any showers in here, and then it’s back to a big bubble high, but this time cooler again.
