DAYS 1-5 (OCTOBER 4-8)

Our weather continues to be controlled by a large high pressure area which will provide fair weather and a warming trend for the next few days. As the high center settles off to the south and east, a trough will eventually approach from the west, and the first thing you’ll notice from this is a more prominent wind by Tuesday. Eventually, a cold front will push a band (or two) of showers through the region at some point between Tuesday night and midday Wednesday – based on current expecting timing. A cooler air mass arrives behind this, but up until then, other than cool early mornings today and Sunday, and some cooler afternoon sea breeze in coastal areas this weekend, the next several days will recall the days of summer.

TODAY: Sunny. Highs 72-79, cooler in some coastal areas. Wind W up to 10 MPH becoming variable with coastal sea breezes.

TONIGHT: Clear. Lows 53-60. Wind variable to SW up to 10 MPH.

SUNDAY: Sunny. Highs 75-82 though a little cooler along the coast. Wind SW up to 10 MPH becoming variable with coastal sea breezes.

SUNDAY NIGHT: Clear. Lows 55-62. Wind SW up to 10 MPH.

MONDAY: Sunny. Highs 76-83, again a little cooler South Coast / Cape Cod. Wind SW 5-15 MPH.

MONDAY NIGHT: Clear. Lows 55-62. Wind SW 5-15 MPH.

TUESDAY: Sunny to partly cloudy. Highs 76-83, except cooler South Coast / Cape Cod. Wind SW 5-15 MPH.

TUESDAY NIGHT: Mostly cloudy. Showers likely overnight. Chance of a thunderstorm. Patchy fog. Lows 60-67. Wind SW 5-15 MPH, higher gusts possible.

WEDNESDAY: Mostly cloudy with showers likely in the morning. A sun/cloud mix in the afternoon. Highs 68-75. Wind SW 5-15 MPH with higher gusts, shifting to NW.

DAYS 6-10 (OCTOBER 9-13)

High pressure brings fair weather early in the period and again later on, after a brief interruption from a frontal passage with a chance of a shower sometime October 11. Temperatures warm up pre-front, then cool down behind it.

DAYS 11-15 (OCTOBER 14-18)

Overall dry pattern expected, but a few hints showing up in guidance of a more prominent trough trying to move into the region later in the period that could bring a shower threat and cooler weather. This is not a high confidence outlook and I’ll monitor trends.

    1. Sort of. It’s really defined as occurring after the end of the growing season, but the term’s usage got broadened to include any warm weather in autumn. 🙂

        1. I’m sure you’ve heard the local TV folks mention it. I know they do. I have here as well.

          While I can be a stickler for the definitions, I don’t really mind it being used as a general term for autumn warmth, but the origin was really about the warmth that would come after the first killing frost. 🙂

  2. Good morning and thank you TK.

    52 overnight, 55 now

    Ocean temp: 61. (Boston buoy)

    Wordle: 5

  4. I got Worde in three.

    My first guess was kind to me! I got two letters in the right position and one other in the wrong position.

    2. We’re going to call you Mr. Threester.
      Great job!!!

      I keep experimenting with starting words. Sometimes they work out great and at other times they suck really badly.

  8. Turns out my old mind sometimes works. Indian summer is after killing frost and closer to end of October and early November. As far as changing parameters….well, everyone know how I feel
    About that. I’m sure soon the name itself will be changed 🙁

  9. Joshua. I went back to find the link to your healthcare article. I can’t seem to find it. I apologize. Would you mind sharing the link again please. And thank you !

  10. I really enjoy earth astronomy data.

    Yesterday, earth was exactly, at some point during the day, 93 million miles from the sun.

    The earth is now 1.5 million miles closer to the sun than it was around July 4th, when it was at aphelion. It’s got another 1.5 million miles to get closer to achieve perihelion in early Jan.

    The benefit to this for the northern hemisphere is summer is 93 days and 2/3rds of a day long, while winter is almost exactly 89 days long, though it feels about 200 days long to me. 🙂

    1. Over a long, long period of time, as the earth also rotates slowly with respect to the direction the North Pole points to, the northern hemisphere will experience perihelion at the summer solstice and aphelion at the winter solstice, 10 or 20 thousand years from now.

  11. The sun still feels just as hot as in July, at least to me when outside with no shade. Tom, what is the sun angle equivalent for early October?

  13. Temps ~70 now with dew points upper 40s to lower 50s (some mid 50s South Coast). Glorious early autumn day today.

    You can definitely feel the difference now being in the sun, despite it being warm there, it pales in comparison to the higher sun angle of mid summer. My 1 1/2 mile walk around this area just illustrated that nicely.

          1. Thanks Tom, JPD, TK.

            I took a walk to pick up my prescription and that sun felt more like July 8-10!

            Unfortunately most of my walk to the CVS is in full sun with no trees or buildings along the Southern Artery.

  15. I love this weather ! About to take in a field hockey game.

    I’m especially appreciative of this weather given that I’m thinking we’re going to see a colder and at least slightly more snowy winter than the past 2 (which won’t be difficult to achieve).

  16. Thanks for clarification on Indian summer, TK!

    Whatever we’re having and often have in autumn – I know of only a few mostly cloudy/dreary autumns in Boston in my lifetime – they are NOT having in Northwestern Europe. Rain/wind is the theme. Today’s been quite the crappy day. Spoke to my daughter in London and ex-wife in Amsterdam. Both described it as typical fall weather. Autumn is NOT their glorious season. That’s for sure. I keep repeating myself, but I do think the Pilgrims must have been in a state of shock at how nice fall is here. Usually SO much sun; comfortable temperatures; not a lot of wind. It’s not what they were used to. They probably also thought, “but at the end of November 1620 when we arrived it was so cold and even snowy … what’s happening this year [1621].” Soon enough, they learned that dramatic seasonal change is a thing in New England, but not in Old England.

  20. Philip, I agree with you that the sun feels warm to hot, particularly earlier today. I think some of it has to do with how dry it is. I’m unsure whether this is the case. But I think that when in drought, the sun can feel warmer.

    1. An early March sun doesn’t feel “blistering” like today. That’s the way I would describe it. Thankfully dewpoints are low.

      1. We also only have average highs in the 40s in early March. 😉

        Today, it was much warmer than that. Not hot, but much warmer. That makes a huge difference.

    2. Technically there’s no difference in how warm it feels given identical conditions in drought or non-drought. It has more to do with the dew point. Higher dew point will make it feel warmer. Lower dew point will not. Today, the dew points are quite low.

    1. Mostly muted. There are certainly some nice yellows, but little in terms of reds or oranges. Keep in mind, that we have MUCH more forest and woodland and variety of trees than most of the heavily populated areas of Europe. This also applies to some of the least densely populated areas, such as Northern Scotland where there are comparatively few trees

      Parts of Scandinavia look a bit like Northern New England. And the Ural mountain range in Russia does, too. The Urals and Appalachians share certain characteristics, including their age and rounded tops but also similarities in climate when we compare it to Northern New England.

  22. Today we hiked in Petersham near the Swift River. The weather was perfect!

    The water flow in the river is very low.

    Not to be outdone by the old folks 🙂 my son and two friends hiked up Mt. Washington. They were at the summit at 2:00 and the conditions were great there too. The temperature was about 50 F, the wind was about 30 mph, and the visibility was good.

    1. A special day for you all. Some color up that way. Drought ugly down here so far. And wow that is low

  23. Logan was sea breezed and in the 70s most of the day, but when the wind went SW for a little while, they spiked to a high of 81. The record of 86, as expected, was not challenged.

    3. It was quite warm and hot in the sun watching field hockey, but has cooled very nicely this evening at the campground.

  24. Toronto clobbered Yankees 10-1. Good start! 🙂

    Aaron Judge struck out with the bases loaded in the 6th. 😉

    1. Im hoping for the Yankees. Yes there is a rivalry, but we gave WHW folks who are Yankee fans.

    2. Go Jays!
      As a Sox fan I am not going to root for the Yankees. 🙂
      They sent us out. Now it’s their turn. 😉
