DAYS 1-5 (JUNE 18-22)

A warm front moves through this morning with some showers around, and our humidity begins a spike which lasts through Thursday, along with the addition of some heat. Behind today’s early showers may come a stray sprinkle, though a disturbance passing by may kick off a heavier shower or thunderstorm near and south of I-90 tonight. The next round of storms is due later Thursday with the approach of a cold front. Timing still looks late enough that we make it through the majority of (if not all of) the daylight in the WHW area without much activity, though northern and western areas could see the first storms pop up before we get to evening – something to watch. I think the main batch of storms ahead of the front will max out to our west and arrive / cross the region while weakening in the evening and nighttime hours, exiting overnight with the passage of the cold front. This leads to a less hot / still warm, and less humid day on Friday, with only a slight chance of a pop up / passing shower or thunderstorm as an upper disturbance swings through the region. High pressure brings fair, seasonably warm, and dry weather Saturday. I’ll be watching upstream for the development of a complex of thunderstorms (Upper Plains to Upper Midwest Friday night, moving across the Great Lakes during the day Saturday). This system, probably in a decaying state, would dive east southeastward across New England in the early hours of Sunday – after midnight to shortly after sunrise. While the bigger impact of rain and wind would likely take place north and west of our region, a gusty shower or thunderstorm may visit some areas to start the day out on Sunday, but the remainder of the day, assuming my timing is correct, would be quite nice. We welcome summer official with the occurrence of the solstice at 10:41p.m. on Friday June 20…

TODAY: Mostly cloudy. Showers and a slight chance of thunder this morning. Patchy fog until mid morning. A spot sprinkle or light shower this afternoon. Highs 76-83. Dew point 60+. Wind S 5-15 MPH.

TONIGHT: Variably cloudy. Patchy fog. A shower or thunderstorm possible near and south of I-90. Lows 62-69. Dew point 60+. Wind S to SW up to 10 MPH.

THURSDAY: Partly sunny. Chance of showers and thunderstorms, favoring late-day or evening and favoring areas west and north of Boston . Highs 78-85 South Coast, 85-92 elsewhere. Dew point 60+. Wind SW 10-20 MPH.

THURSDAY NIGHT: Variably cloudy. Chance of showers and thunderstorms favoring eastern areas early. Areas of fog. Lows 60-67. Dew point 60+. Wind SW 5-15 MPH, variable near storms, shifting to NW overnight.

FRIDAY: Sun/cloud mix. A passing shower or thunderstorm possible. Highs 78-85. Dew point falls below 60. Wind NW 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Lows 57-64,. Wind NW 5-15 MPH.

SATURDAY: Mostly sunny. Highs 78-85. Wind NW 5-15 MPH.

SATURDAY NIGHT: Clouds arrive. A shower or thunderstorm possible overnight, mainly north and west of Boston. Lows 60-67. Wind W 5-15 MPH, higher gusts.

SUNDAY: Lots of clouds early with a shower or thunderstorm possible Boston area southward, then mostly sunny. Highs 80-87. Wind W 5-15 MPH, higher gusts.

DAYS 6-10 (JUNE 23-27)

A couple / few days of hotter weather are probable early to mid next week, but we also have to watch a frontal boundary to our north that with adequate push could make some areas, especially northern areas and eastern coastal areas, significantly cooler. Can’t rule out a few showers and thunderstorms in a hot air mass and near any frontal boundary.

DAYS 11-15 (JUNE 28 – JULY 2)

General west northwest flow pattern with a a couple disturbances to pass by. These can bring a few showers and thunderstorms, but most of the time looks rain-free with variable temperatures averaging near to above normal.

  1. Thanks TK !

    Day 180 …… ahhhhhhhhhhhhhhhhhhhhhhhhh 🙂 11:15 am dismissal.

    Was it easy to type in mostly sunny for Saturday ? 🙂

  4. On Raffy, a final thought, I do not like smear campaigns and corporate speak. While the current ownership has helped facilitate 4 championships this century, for which I’m grateful, I am annoyed at their way of dealing with certain players. Devers is exhibit A, in my opinion. Here’s Pedro Martinez on the topic. https://x.com/tylermilliken_/status/1935168729903677505

  5. Happy Birthday Vicki! I hope you have a wonderful day.

    Let us know if you hear from a certain knighted musician who shares your day. 🙂

    1. Thank you. When I was a teen, I sure thought it made me very special since Sir Paul and I share a birthday!!

  6. Thanks, TK!

    HAPPY BIRTHDAY, VICKI! 🙂

    Congratulations on your last day of school, Tom!
    Have a great summer break!

  9. Thanks TK
    Happy Birthday Vicki

    SPC will update tomorrow’s outlook around 1:30 this afternoon.

  11. Heat Advisory up for Boston Worcester area extending to parts of the south shore from 11am to 8pm Thursday. I would not be surprised to see heat alerts issued for early next week. Watching the potential for locally strong to severe thunderstorms late tomorrow afternoon and evening.

  14. My Struggles with WORDLE continue.
    Took all 6 guesses to get today’s word, which was actually
    pretty easy, yet not for me, today anyway. That first word is so important. In fact my first 2 words yielded no letters. All it did was eliminate letters. Oh well, I’ll keep trying….

    1. I didn’t solve it at all!

      I had every letter except the first one in the right place on the third guess. For the first letter I tried B, L, P, and H with no luck.

      1. Well, I don’t feel so bad. For a simple word, it was difficult.
        AND I LOVE to EAT, so I “should” have gotten this word!!!!!
        INTERESTING game for sure. I’ll keep playing.
        Thank you and Vicki for introducing me to this fun game.

    2. Choices are the most difficult and get everyone. There were a lot of them with this word. I managed to get very mucky and ended with a four. But I groaned when I saw the word because the number of choices was huge.

      Thank you, JPD, for bringing Wordle here. It is a fun game. But maybe more fun when you compare with others.

  17. Quick peak at the SREF for tomorrow only place in SNE in the low tornado risk is the Berkshires.

  24. Thanks TK! Happy Birthday Vicki – thank you for the kindness and compassion you bring to this group. Congrats to the teachers on their last day – I expect there to be even more comments in these summer weeks.

  25. At the Amundsen-Scott South Pole station it’s a brisk -79F. It looks like it will cool down further to around -90F by Saturday. And yes, there are people staying at that base. Who knows, maybe I’ll take a trek down there at some point in my lifetime.

  30. ICON goes ballistic on Tuesday:

    FMH 100
    BOS 101
    MHT 101
    LWM 102
    ORH 102
    ASH 103
    OWD 103
    BED 103
    EWB 104
    PVD 104
    BAF 104
    BDL 105

  31. Karen Read found NOT GUILTY except on the DUI charge.
    She had a great defense team, else she would have been in big trouble. From What I have seen and read, this was well justified.

  33. The GFS .. is .. SO … bad. Two of its major biases show as a result of a mesoscale storm complex that likely forms in the Upper Plains / Upper Midwest Friday night, and reaches the Northeast by early Sunday. While the details of that system, discussed by myself and by SAK in our respective blog posts, are still a little bit up in the air until we actually have a complex to track, the GFS has its ideas … Most likely a system like this would blow through New England or southeastern Canada (whatever the track) and eventually dissipate, or maybe be absorbed by something else, depending on the synoptic set up. But the GFS shows 2 of its biases…

    1) It takes the decaying system further south than other models, which is likely an error. It ends to curve anything low pressure related too much to the right. This is why you see it develop these tight strong lows that then drift southward on a lot of its model runs. In this case it takes the remains of the MCS and turns it into a southward moving low off the Mid Atlantic.

    2) Guess what the GFS will do with virtually any low pressure system off the Mid Atlantic, Southeast, or in the Gulf? You got it! It pretty much tries to turn the remains of the MCS into a quasi tropical system that then makes landfall in the Southeast a few days later. Hilarious…

    1. The GFS is also about 15-20 degrees cooler around here on Sunday than every other model because it is farther south with the system and keeps the clouds/showers around longer.

      1. I’ve really become disenchanted with that model. There are days are I barely even look at it, and it’s not having a negative impact on my forecasting. Ah well, once a better tool.

  36. January 29, 2022 ❄️

    Just wondering, do most who are convicted of OUI receive probation?

    Only the “snowflakes” know for certain WHAT really happened that snowy day/night.

    1. Don’t know, but after enduring not 1, but 2 trials, I would say probation is appropriate. Just my opinion.

    2. I believe meteorologist Rob Gilman testified during the 2nd Karen Read trial. Don’t know if it was for the prosecution or the defense. ❄️

  37. Nws fairly bullish on heat for tomorrow and severe weather West of the coastal plain.
    I am conflicted. One thing I am ppretty sure of, No Storms for the coast, certainly not severe. Re: heat, don”t know. it is possible Boston stays under 90, then again they could go 93 or 94. With the high dew points, it will be miserable either way.

    1. They’re overdoing the heat. The parameters are not good for really high heat. 92 or 93 tops for Logan. A 95 can occur in Norwood and/or Fitchburg. Normal hot spots. Nothing really special about this.

      Also, the timing is really late for severe weather east of the CT River Valley.

  38. Non weather question. I’m again looking into moving from verizon internet and cable. I mostly use streaming apps. Except jeopardy and hallmark. I can find hallmark on frndly but I can’t find jeopardy on any streaming service.

    Anyone??

  39. The evening activity prognosticated to occur near and south of I-90 has materialized just to the west and will be doing its thing in the expected area over the next several hours. Doesn’t look like anything too impressive, not was it expected to be.

  42. Red Sox:

    Won 4th series in a row
    2-1 since Devers trade
    Yankees have lost 6 straight games
