DAYS 1-5 (JUNE 3-7)
This is going to be a “big diurnal” day. We haven’t had many of those this spring with an active pattern of wind and cloud cover preventing such set-ups, but today’s is ideal. Overnight, high pressure moved in and some initial clouds dissipated and moved out, leaving us with clear, calm conditions. Temperatures responded by falling quickly – a process known as radiational cooling – an idea set-up where any warmth from the day radiates easily to space as the air is not mixed by the wind. But today’s atmospheric set-up, with high pressure moving in aloft and the surface high center shifting to the south is one that allows a strong warm up. Often in this set-up, your coolest morning spots become your warmest afternoon spots, so areas like Taunton MA, for example, that sit in the lower 40s as of sunrise for low temps, will probably peak around or just over 80 for a high temp – a nearly 40-degree “diurnal” or difference between morning low and afternoon high. A location where the diurnal will be much less will be Boston’s Logan airport, sitting in the upper 50s early this morning without the full benefit of radiational cooling, eventually to have their temperature rise thwarted by a weak sea breeze, so they go from the upper 50s to perhaps near 70, a “diurnal” or only around a dozen degrees. These specific examples suffice to explain our late spring set-up today with the exception of the rest of the details of the sky conditions. A few patchy mid level clouds may appear in the sky later, and a few fair-weather cumulus may pop up during the day, but the sunshine minutes will be much higher than previous recent days. One limitation will be the trend toward more filtering of the sun by an increasing wildfire smoke plume aloft (from Canada). This will be with us into tomorrow as well, as we have a slightly more pronounced west to southwest wind and a warmer day, even for eastern coastal locations. It’ll be the South Coast most affected by the ocean air in Wednesday’s set-up. Thursday continues the warm up, even qualifying for a “hot” day for areas away from the South Coast as we make a run at 90 – a few places reaching it – and a little more humidity with dew points reaching or breaking 60. A cold front will be approaching from the northwest later Thursday, but its approach will not be aggressive and it also will have limited moisture to work with, and the lack of triggering mechanisms for convection, so I suspect as of today’s update that Thursday’s shower and thunderstorm chance will be minimal, with isolated activity favoring areas well west and north of Boston later in the day. The tricky part of this week’s forecast continues to be the Friday/Saturday time frame when the aforementioned frontal boundary will sag into our region and hang around for a while, and we watch for 1 or 2 waves of low pressure to drift up our way from the southwest. Yes, once again this means our wet weather chances increase as we head to week’s end, but what I need to still work out as timing of greatest shower and thunderstorm chances. At “days 4 & 5” there really is no way to know the finer details of convective development and the smaller scale triggers that don’t exist until these showers and storms exist, which play a significant role in governing their behavior, so I’m at a loss of ability to go into much detail just yet other than saying that Friday and Saturday look humid and unsettled.
TODAY: Sunshine, patchy clouds, and variable high altitude smoke, tending to increase later in the day. Highs 71-78 except 63-70 South Coast. Wind SW 5-15 MPH.
TONIGHT: High altitude smoke. Lows 52-59. Wind SW up to 10 MPH.
WEDNESDAY: Sun filtered through high altitude smoke. Highs 78-85 except 70-77 South Coast. Wind SW 5-15 MPH.
WEDNESDAY NIGHT: High altitude smoke. Lower elevation fog patches. Lows 57-64. Wind SW up to 10 MPH.
THURSDAY: Smoke aloft may thin somewhat with filtered sunshine, otherwise a sun/cloud mix. Isolated late-day showers and thunderstorms, favoring areas north of I-90 and west of I-95. Highs 85-92 except 77-84 most of South Coast and 70-77 Cape Cod. Dew point 60+. Wind SW 5-15 MPH.
THURSDAY NIGHT: Variably cloudy. Patchy fog. Lows 60-67. Dew point 60+. Wind SW to variable up to 10 MPH.
FRIDAY: Variably cloudy. Chance of showers and thunderstorms. Highs 78-85 except 70-77 South Coast. Dew point 60+. Wind SW to variable 5-15 MPH.
FRIDAY NIGHT / SATURDAY: Variably cloudy. Chance of showers and thunderstorms. Areas of fog. Lows 62-69. Dew point 60+. Wind variable 5-15 MPH.
DAYS 6-10 (JUNE 8-12)
Currently leaning toward a push of drier air and return to fair weather to finish the weekend on June 8, fair weather early next week and unsettled weather with a trough and frontal system approaching by mid week. Temperatures variable, but not extreme.
DAYS 11-15 (JUNE 13-17)
At least one round of unsettled weather, favoring later in the period. No major temperature extremes indicated.
Thanks TK.
Thanks TK !
Excellent discussion on diurnal temps !!
Good morning and thank you TK.
Thanks TK

60 here currently after a low of 52.
I expect 75-80 here as I don’t think any sea breeze makes it this far.
We shall see. temperature is rising pretty well so far.
Beautiful out there this morning.
I don’t know if it got mentioned yesterday, but I read an encouraging story yesterday that the NWS is being allowed to rehire 125 positions to fill some of the very understaffed ofcs around the US. (I think that was the gist of it)
That would be good news! thanks
Thanks, TK.
Don’t turn to social media! This will probably be represented as a Cat 5 crossing the Benchmark.

Thane you, TK. Awesome discussion.
Up to 55 from low of 44
66 here already and warming rapidly!!
Tom, I saw your nws post. I sure hope you are right.
Heather Cox Richardson mention nws, noaa, and fema in her discussion this morning. I copied that part and put on the noaa/nws discussion page here.
I found this also. It’s definitely something but still way down from a service that was already short staffed. HCR’s words are very worrisome
https://abc7ny.com/amp/post/national-weather-service-adding-around-125-new-hires-laying-off-hundreds/16634289/
Hopefully just a start!
I hope so.
Thanks, TK.
Thanks, TK…
Our principal has the extremely tough decision whether to hold Saturday evening’s (6 pm) graduation outside in the stadium or move it indoors to the gym by tomorrow. There’s only enough furniture to set up in one location. The decision has to be made by tomorrow. It’s breaking his heart.
Darn. That is so difficult. Hopefully folks will all understand and be kind.
Good luck to him !
Some conflicting info on the models that go out that far right now.
Too bad he can’t buy another 36-48 hrs to make a decision Thursday morning or Thursday afternoon.
District can pay a few extra people to help the custodial staff set up in less time once a decision is made.
What do you think, Tom, knowing what you see in the Saturday afternoon forecast? Go or no go in the stadium?
Well, its not a chilly, cold set-up where even if it wasn’t raining, it would be raw, chilly and drizzly to be outside.
This is a milder, more humid setup where if its not raining, it would be comfortable to be outside.
If it’s a decision that has to be made by Wednesday, I think one has to play it safe and choose inside.
If the decision can be held up to later Thursday, then your within 48hrs and I think it could be made with increased confidence, as compared to making it 72 hrs out.
Thanks, Tom…
I copied and pasted your notes and sent them to the principal. Great weather tonight for their Senior Prom at Granite Links in Quincy!!!!
Up to a delicious 70 here and destined for higher.
70 at Logan with a SE sea breeze at 9mph.
Logan has now dropped to 68 with that sea breeze.
71 here.

For perspective, its quite hazy in Toronto with the sun struggling to shine through the smoke.
So, it has to be literally fairly dark under that brown blanket in Manitoba. The upper low is just fanning those fires south of it. Maybe a lobe of energy on its south side can drop some showers, but the temp/dew point depressions are large, so I don’t know how much of that is evaporating.
Then 2 provinces to the left, can see a smaller trail of brown smoke.
Have to wonder about the butterfly effect here.
How much solar radiation that should be otherwise reaching the ground, now is not.
So, that then can affect the current jet stream, which will effect the future jet stream. Smoke could alter the jet stream which could affect the track of a future tropical system. To be fair, it could be a good change too. But, also a bad change.
Made it to 71F and should hit higher.
Maybe you have done this and I missed it, but has there been a summer outlook regarding heat waves, humidity etc? We just tuned up our AC but it is old will soon need updating. Hoping we don’t have a scorcher.
Thursday may very well be a scorcher, if you call 90-92 a scorcher.
Certainly will feel that way compared to what we have been
experiencing. Good luck,
I will be installing at least one AC today, if not 2 or 3.
We generally run with 3.
I have not, but it looks near normal / near normal, averaging out the stretch. Typical variability to be expected.
73 here, 66 at Logan
For those of you who are interested, my latest batch of Forbes articles (I believe the first 4 each month are free; you can pick and choose which ones you wish to select). The topics run the gamut from the most favored nation model to lower drug prices to the World Health Organization to obesity drug coverage by insurers to the abortion pill to a blood test for Alzheimer’s. Something for everyone, I guess. https://www.forbes.com/sites/joshuacohen/
78 here. Went up quickly till 10ish then slowed a bit.
74 here with an East wind. 66 at the airport.
Last evening Eric said there would be a shallow sea breeze and he further explained that it meant that the sea breeze would only penetrate a mile or so inland. NOPE, try at least 6 miles. 🙂
btw, 81 at Norwood. What does this mean for tomorrow??????
It’s warm out but I have fever-related chills. Not Covid (I tested). But it’s my annual summer virus. Raspy, smoker’s voice, sore throat, the works. Throughout my 60 years of life, I tend to get more colds and flus in summer than in winter. Go figure.
Feel better asap!!
Hope you feel better soon
The media continues to be more predictable than the weather. Those news directors are driving hard on the “another rainy weekend coming up” thing. No. Virtually NONE of the weekends in this stretch of unsettled weekends has been unsettled for the whole weekend! It’s nearly always been a portion, with significant dry hours?
And hey! I think this coming weekend’s dry hours will outnumber last weekend’s – and there were quite a few dry hours last weekend too. So…
#JustKeepingItReal
Topped out at 75 here today making the low end of my predicted range of 75-80. Very very very nice day!!!!!!!!
Some deep blue sky’s in between the storms down here in Sarasota today. Looks like a slowly developing low pressure area over the state then heading north east in a day or two. The media will blow it up to a cat 5.
Thanks TK.
My son’s high school graduation is this Saturday at 10AM and they are dealing with the same dilemma here as they are at Captain’s school. It is normally held outside at the football field but in the event of rain, they move it inside to the auditorium and every family is restricted to 6 tickets. Unfortunately I dont see how this isnt going to be moved inside. With the forecast for likely showers much of the day, I’m sure they will play it safe, even if there is the potential that the rain holds off until afternoon. Real bummer as we need to now pick and choose who goes.
Actually just got an email from the superintendent saying he has been in touch with the school’s on call meteorologist and the outlook “isnt looking good” but they are going to hold off on making their decision until Friday in case the forecast improves.
Sounds as if he’s been talking to TK. I wish the very best for your sons class and all graduating classes ❤️
Thank you Vicki!
Air Quality Alert up for all of CT tomorrow and Thursday due to the incoming smoke.
Have we seen SSK. I remember he was not feeling well last I saw a post but I can easily have missed one
He’s doing ok! Was in touch earlier.
Good. Thank you.
Mark, congratulations to your son, to you and your family!!!
Here’s hoping your son’s class and our seniors can graduate outdoors Saturday and that all of the guests can attend the ceremonies without restrictions!
Thank you Captain!
Skies getting smoky here and the sun was a fiery orange earlier before it disappeared behind some clouds off to the west.
Red Sox lose their 17th one-run game.
* 10 GB the Yankees
* 5 games UNDER .500
* 11 LOB
* 53 errors to date: most in MLB.
I watched last night. It can be painful!
