DAYS 1-5 (AUGUST 20-24)

Today’s weather will be cool and mainly cloudy as a disturbance from the northwest moves through the region and undergoes a minor interaction with Hurricane Erin, which is still quite far to our south southeast today. The initial batch of rain aims more north of I-90 this morning to early afternoon, with the focus then shifting more to the south from midday onward. Any rainfall we get right now is beneficial as the region has had quite a dry summer. Temperatures today will run considerably below average – many double-digit departures, so keep that in mind as well if you have outdoor plans. A summary of Hurricane Erin’s main impact on our region… Large long-period ocean swells and rough surf, increasing today, peaking Thursday through early Friday, diminishing later Friday into the weekend. The other will be some gusty wind, especially across southeastern MA, later Thursday into Friday as the storm makes its closest pass during a time its wind field expands significantly (normal for a tropical cyclone in the process of transitioning to post-tropical). There will be no impact from rainfall. We’ll see the high cloud shield from the storm spread over at least a portion of the sky during Thursday before departing during Friday, which will filter / dim the sun Thursday afternoon and Friday morning. This set-up does leave the potential for a spectacular sunset, however, on Thursday evening – something to watch for if you’re a photographer or just like to observe. During all of this Thursday and Friday we’ll have dry weather, and while it won’t be as chilly as today, temperatures will still run significantly below normal on Thursday and slightly below normal on Friday. Our weekend will feature mainly dry weather and a warm-up but with tolerable humidity, only a little more humid Sunday, felt by the most sensitive people. An approaching cold front looks a little slower based on recent guidance trends, so I’ll hold off the previously-forecast shower and thunderstorm threat during Sunday to the evening and nighttime hours on this update, but keep an eye on that for any other trend changes.

TODAY: Mainly cloudy. Periods of rain. Highs 61-68. Wind E 5-15 MPH.

TONIGHT: Mainly cloudy. Some rain lingers especially south evening. Chance of some drizzle and fog eastern coastal areas during the evening. Lows 54-61. Wind NE up to 10 MPH.

THURSDAY: Patchy low and middle clouds mixed with sun in the morning. Sunshine dimmed at times, especially southeast, by increasing high clouds during the afternoon. Highs 68-75, coolest coast. Wind NE 5-15 MPH inland, 10-20 MPH coast except 20-30 MPH Cape Cod with higher gusts likely.

THURSDAY NIGHT: Considerable high cloudiness. Lows 58-65. Wind NE 10-20 MPH except 20-30 MPH coastal areas especially south of Boston including higher gusts.

FRIDAY: Limited sun early with lots of high clouds, then increasing sun. Highs 75-82, coolest coast. Wind NE 15-25 MPH, strongest coastal areas, except 25-35 MPH Cape Cod, including higher gusts during the morning, shifting to N and gradually diminishing during the afternoon.

FRIDAY NIGHT: Mostly clear. Lows 56-63. Wind N to NW 5-15 MPH.

SATURDAY: Mostly sunny. Highs 78-85, a bit cooler at the coast. Wind variable up to 10 MPH with light coastal sea breezes.

SATURDAY NIGHT: Mostly clear. Lows 60-67. Wind SW up to 10 MPH.

SUNDAY: Partly cloudy. Showers and thunderstorms possible evening or nighttime. Highs 81-88 except cooler South Coast. Wind SW 5-15 MPH.

DAYS 6-10 (AUGUST 25-29)

A slower-moving frontal boundary and some potential additional moisture from the south brings a better chance of showery weather for August 25. Turning dry and cooler August 26-27. Next disturbance / front may bring a shower or t-storm August 28 before fair weather returns later next week.

DAYS 11-15 (AUGUST 30 – SEPTEMBER 3)

Indications for the August 30-31 weekend are for fair, dry, cool to mild weather, with continued fair weather for Labor Day (September 1) and a warm-up heading toward the middle of the first week of September. While a dry pattern is good news for outdoor plans, it’s not good news for building drought in the region.

    1. Thanks! Most of the rain will have fallen there but I’m not really going for “the weather” anyway. 🙂

  5. Thanks TK !

    Safe travels to Lake George !

    Didn’t get the word in Wordle, today. Just didn’t see it with what I had.

    1. I just flunked also Tom. I was so aggravated by the 6th try that I put in something I knew was wrong just so I could see what the stupid word was. 🙂

    2. I FAILED as well. I thought it might be that word, but for the life of me I could NOT remember how to spell it, so FAIL.
      3 FAILS today. WOW!! that might be a first. 🙂 I don’t feel so badly then. thank you.

    3. It was five for me It’s a really tricky word. The words seem to be more challenging every day.

        1. Wednesday, September 3rd the students start.

          We have all the staff mtgs Tuesday, September 2nd.

          Next week, I’ll go in early in the week to get my room ready and then, Thursday, I’ll go in during the morning for 6th grade open house to walk through the clusters, etc.

          I’m kind of ready to get going. Remind me I said this in October 🙂

    2. Yikes. I seem to remember Bob for his flooding and Gloria for her winds. I do remember Mac up and down a million times catching a roof leak. And we only had a ladder for attic access back then. On his birthday no less

  9. Enjoy your day TK!

    I grew up about 60 miles south of Lake George and went there many times.

    1. 1938
      INSANE. There is a similar marker along the Deerfield River, I Believe I recall seeing it somewhere along it. Very difficult to imagine that kind of flooding!!!!!

  12. Anyone want to goo out on a limb and predict how strong the winds get on South Coast? Any chance a tropical storm watch is issued?

    1. If I go out on a limb, it would be sure to BREAK!!! Sorry can’t help you as I would be wrong no matter what I said. 🙂

    2. Are you just west of buzzards bay, cause the smooth surface of buzzards bay, with NNE winds might add a few mph to towns on the western side of the Bay.

      Sustained 15-20 with gusts to 35 mph ???

      1. Yes – right at tip of South Dartmouth – this is one stubborn Hurricane still drifting a bit west of north

  15. https://www.goes.noaa.gov/sector_band.php?sat=G19&sector=eus&band=09&length=24

    Text book, perfect upper environment over Erin.

    Massive evacuation of air above the hurricane in all quadrants.

    I don’t see any sign of it on the water vapor loop, but always have to be aware of any moisture at any level of the atmosphere working its way up into this separate disturbance passing through us today.

    Cindy F on channel 5 did an outstanding presentation of this on her weather cast this morning.

    I am at the seawall and I can report a steady ESE wind.

    I can see some area well south of the mass pike making the 2-3 inch rain total before this ends overnight. We’ll see.

  19. Let’s Go Fairfield CT today against Nevada. If Fairfield wins they are in the U.S. Championship this Saturday. The rain has moved out so good to go for the game at 3 this afternoon.

  22. Connecticut-Nevada, 3-3 after 3. CT playing some incredible outfield defense in the third!!!!

  23. Despite what the radar showed, not much rain here. 🙂
    Sure there was some light intermittent rain, but that was about it.

    I see much heavier rain to the South.

        1. Is this a concern for your basement?

          I Just almost doubled to 0.55. Hoping son in lincoln is getting a good amount. Blackstone river canal behind his house is dry

          1. No. It’s been so dry here. We did get over an inch last week though.

            How has your basement been since the leaking a few years back?

  27. Fairfield CT gets two more wins it will be the first little league world series title for CT since Trumbull in 1989.

  28. I love watching the Little League World Series every year. When you have a team from your state making a run all the way to the U.S. Championship game it makes it extra special. Fairfield last three games beating a tough Hawaii, South Dakota, and Nevada team. Hopefully this Fairfield team could bring home a little league world series championship back to CT!

    1. I feel the very same. I cannot remember when Mac and I started watching. I know we were at Humarock when we discovered it. Many years ago.

  29. My grandson asked me if someone here could tell him how hurricanes names are chosen

    Thank you !

  30. Looks like Erin finally making that easterly turn. Still a lot of rain heading towards the South Coast – maybe another inch plus. Alway interesting to watch how the climate acts when there is a hurricane lurking around.

  32. Erin has yet to make landfall anywhere in the Atlantic. Any chance she makes it to Europe?

    2. Remnants will. Most of the time they do in one form or another.

      It’s like most of the western Pacific typhoons eventually make it to North America as extratropical cyclones.

  33. Lake George visit was awesome! Celebrated my son’s bday there (his actual bday is next week) with his gf and her family. Got back very late last night.

    Today I’m off to Hampton Beach NH. 🙂

    New post…
