Friday Forecast

DAYS 1-5 (JUNE 9-13)
An ocean storm side-swipes southern New England early today with a wet start over parts of Cape Cod. A disturbance from the west may trigger a few afternoon showers and thunderstorms but when today is over a large portion of the region will have seen no rain at all. This weekend a westerly flow develops and we transition to the feel of summer, but another disturbance may trigger a few showers/storms again on Saturday but it appears these will be only isolated. Then comes a potential heatwave for Sunday through Tuesday, but not for everybody. There will be cooler temperatures in the normal cooler spots such as Cape Cod and the Islands, and by Tuesday we’ll have to see about the timing of a front trying to push down from the north which may cool portions of the region. An interesting note: If Boston should record a heatwave during the Sunday-Tuesday period, it will be the first time that they have seen two heatwaves before June 15.
TODAY: Partly sunny to mostly cloudy. Early rain areas of Cape Cod. Isolated to scattered showers and a slight chance of thunderstorms developing to the west and pushing to the east. Any showers/storms end by evening with decreasing clouds. Highs 62-67 Cape Cod and Islands, 68-75 elsewhere. Wind N 5-15 MPH shifting to W.
TONIGHT: Mostly clear. Lows 53-58. Wind W 5-15 MPH.
SATURDAY: Partly sunny. Isolated showers/thunderstorms mainly mid to late afternoon. Highs 68-75 South Coast, 76-82 elsewhere. Wind W 5-15 MPH.
SATURDAY NIGHT: Partly cloudy. Lows 58-64. Wind WSW 5-15 MPH.
SUNDAY: Mostly sunny. Highs 77-84 South Coast, 85-93 elsewhere. Wind WSW 10-20 MPH and gusty.
MONDAY: Mostly sunny. Lows 63-72. Highs 77-85 South Coast, 86-94 elsewhere.
TUESDAY: Partly sunny. Chance of thunderstorms. Lows 65-73. Highs 77-85 South Coast, 86-94 elsewhere but may turn cooler especially NH and eastern MA later.

DAYS 6-10 (JUNE 14-18)
Fair and mild June 14 as high pressure moves down from eastern Canada. A warmer and hotter and more humid pattern may evolve during the June 15-18 period but along with the threat of a few showers and thunderstorms from time to time as high pressure builds off the Atlantic Coast.

DAYS 11-15 (JUNE 19-23)
Early indications are for a more zonal (west to east) flow with seasonable but slightly variable temperatures and episodes of passing showers.

  3. Thanks Tk . So probably a comfortable sweatshirt night at the ballpark tonight . I was just offered free 3rd base tickets for tonight’s game . My son is very excited.

    2. Great Simon and Gar song, MassBay!!! Keep em coming. I’m truly enjoying them as a start to my day! Thank you.

          1. Good grief. I tend to have to think hard to give my age if someone asks since I don’t pay much attention to age. It just occurred to me that it was 50 years ago this month that I graduated high school.

    1. Neither am I. Hope your wife will be ok.

      At least the BD front will be here by Wednesday. 🙂

  6. Thanks TK
    Hard to believe with this cool wet weather we have had for most of the spring we could be looking at the second heat wave of 2017 for Boston and Windsor Locks, CT.
    Back on this day in weather history the F4 Worcester tornado.
    Here is your fantasy severe weather sounding from the 18z GFS last night at hour 360.

  7. It was 18z GFS from yesterday at hour 360. Fantasy to say the least but one I never hope to see the day of or day prior to the event.

    2. Still there somewhat on the 6Z run. Let’s see IF it is still around come this
      morning’s 12Z run. 😀

  9. I agree with you fat chance of that happening. The amount of instability shown at hour 360 of the 18z GFS is what you see in the Plains when they have there big severe weather outbreaks.

  10. Midday Notes……
    * Next update will probably bump temps up a bit Sunday Monday and Tuesday.
    * Cold front from the north should be late enough to allow many areas to achieve a heat wave.
    * The next few weeks may allow some powerful disturbances translating to some pretty significant severe thunderstorm threats.

  11. TK you got my attention with your last statement about severe thunderstorm threats.
    Instability showing up for storms on Tuesday with latest 12z GFS run.

  12. Thanks TK can’t wait to hear your thoughts on those thunderstorms threats you mentioned and why you think they could be significant.

  14. With the timing of the front Tues on the 12z GFS instability across SNE looks greatest between 2-5 pm. The timing will be key as the humidity will be there too fuel the storms. If the timing the 12z GFS is advertising happens some strong storms possible. Of course I don’t put much stock in this solution this far out but there are certainly ingredients there for thunderstorms.

  16. Just had a brief heavy shower in Sudbury. Still raining. Been windy all aft. but got real gusty with the shower.

    1. Sure is dark. Looks as if everything went around me but a fair amount of rumbles in the distance. Traveling southeast.

    1. I literally feel and appear to be surrounded, Ace…..but nothing over me. Sky is still black to southeast. Can’t see north from my office.

  19. Those cells are small in size but some of them are quite potent. A friend just got nailed with very close CG’s and small hail as well as torrential rain. She basically said it was a “classic” and the heaviest storm she’s seen in quite some time.

    1. I can believe it. According to the radar the one now is significantly south of me but the thunder is surprisingly loud.

    1. Worcester EF4 tornado.

      I remember that day as I was living in Norwood, MA as a 6 year old then.

      I have vivid memories of pieces of roofing shingles falling from the sky.
      (To be honest, that was a long time ago. Even though I have that memory,
      I wonder how accurate it could have been?) Norwood is about 30-35 miles
      from Worcester? Something like that anyway.

      1. During the Springfield tornado a few years back I think there were reports of shingles and other debris falling from the sky many miles away too

  24. Vicki it is funny that you used the term “funky clouds” That is a nickname that one of my chase partners and I use for “funnel clouds”. 😉

    In this case, it wasn’t a funnel…but just the reference was amusing to me.

  25. Another little ditty NW of Worcester. Looks as if they are screaming through the south shore.

  26. NWS Taunton for Tuesday
    Anticipate scattered thunderstorms to develop ahead of sagging
    cold front boundary Tuesday afternoon. There may be marginally enough
    vertical shear for a few thunderstorms to be strong, although
    it`s unusual climatologically to experience widespread deep
    convection ahead of a backdoor cold front. Although the 12Z GFS
    model is a little more aggressive with its depiction of
    instability parameters, the 12Z ECMWF depicts a roughly similar
    pattern.

  27. Just missed another here in JP. Rained hard as close as Roslindale and W. Roxbury, but only a few drops here. 😀

    1. My neighbor used to do it early morning, my dad swore by evening (around this time).

      1. Odd. They say evening is not a good idea but my dad swore by this time also and his lawn was always perfect. We had great dads 🙂

        1. Dads always knew better than “they” did. I was never sure who “they” are anyway. 😛

  29. Severe parameters are getting more and more interesting for Tuesday.
    0Z GFS has Cape of 4,000+ joules for Boston and LI of -11. I have NEVER seen
    it that large for Boston. Not in the time I have been watching it. That is huge.

    We’ll see IF it’s still there with tomorrow’s 12Z run. Who gives a crap about the 6Z run
    (Although I will look) 😀

    We shall see.

  30. One thing with the GFS that’s been pretty consistent along with those severe parameters is the timing of the greatest instability for SNE between 2-5pm on Tues. I am not putting a lot of stock in this one model but certainly there are ingredients in place for strong to possibly severe storms with a front cutting through the heat and humidity.

  32. 6ZW GFS still has it, but the parameters are not quite as high.
    Nam and CMC have it also, but again not as high as the GFS.
