DAYS 1-5 (JULY 1-5)
This 5-day forecast period takes us through the holiday weekend as Independence Day is Saturday. July starts off with a spell of hot weather as an upper ridge builds in, though its center remains to our west, delivering heat from the Midwest and Great Lakes, while high pressure at the surface builds to our south, sending in higher humidity behind yesterday’s disturbance and warm frontal passage (which was responsible for some heavy downpours in parts of the region). Being on the eastern side of the “ring of fire” – the zone where thunderstorms can travel around the periphery of the high pressure ridge, we’ll have to watch for those, aided of course by the heat and humidity. Our chances are highest today through early Thursday morning, before they drop off during the day Thursday and through much of Friday when the ridge reaches its most eastward extent. As the ridge backs to the west a little and allows a cold front to drop through the region Saturday, we’ll again face a higher thunderstorm possibility. While this pattern supports high heat and humidity in general over this period of time, there are also modifying factors. They include: Local sea breezes, debris cloudiness from thunderstorm clusters, actual storms with heavy rain, and post-storm cooled air. These can all at least temporarily slow down or take the edge of the heat. It’s also not going to be across the board oppressive humidity the entire time for most areas either. We will see some dew points break the 70-degree mark, but many areas may stay in the 60s for dew points for many hours, and also a westerly wind can occur and create a down-slope effect which can drive down points even lower, especially in the coastal plain. Sometimes when this happens, however, the air temperature can end up higher, but the breeze and lower dew point can compensate for this. Additionally, you may have heard talk of “low temps in the 80s”. That will not be happening either. The closest we will come to that a night or two is a low temperature closer to 80 than to 70 in some of the urban centers, due to the “heat island” effect, most certainly not where the extreme majority of people are trying to sleep. So it’s very important to keep all of this stuff in its proper perspective, which I will for you. So, despite headlines you may have seen, this will not be “the hottest (or the worst) in years”. It will be a hot spell in July, the likes of which we’ve seen many times. Now that we have that cleared up, how about the rest of the outlook heading through the weekend? Well, Saturday is key obviously, since it’s Independence Day, and currently I am leaning toward an earlier-in-the-day frontal passage over a later one. A later one would mean hotter weather and a longer / later chance for showers and t-storms, while earlier could easily cap the temperature rise but also end the shower and storm threat much sooner. Additionally, you may have heard some talk about a front that doesn’t really make it through the region. I also disagree with that idea and believe the front moves through efficiently enough so that we see drier and “cooler” (80s) on Sunday with fair weather, courtesy of high pressure to our north.
TODAY: Variably cloudy morning-midday with a shower or thunderstorm possible. Partly to mostly sunny afternoon with isolated thunderstorms possible. Highs 89-96. Dew point 65+ Wind SW 5-15 MPH, gusts around 20 MPH.

Thanks TK
Mother Nature was my alarm clock just after 4 this morning. Heavy rain lightning and thunder.

Thank you JJ. Love that graphic
Thank you JimmyJames
Good morning and thank you TK.

TK, I see you now have 100 in play for tomorrow.
Pete had 96 for today, 101 for tomorrow and 102 for Friday.
NWS has 96 for today, 100 for tomorrow and 99 for Friday.
Pretty much the top of TK’s range.
So what will it be?
I suspect here, nestled in the trees, we don’t make a 100.
Last year when Logan made 102, we made an even 100 here.
The watch is on…..
Btw re: storms yesterday
We just missed here. We got a touch of light rain, that just barely dampened the pavements. No puddle, nothing to show for it. JUST missed us to the North.
I see that Logan picked up 0.16 inch. (Based on echoes, it sure looked like they got more than that)
Excellent 4, JpDave !
Thank you sir
Their rain gauge (and thermometer) are f’ed. Especially the former. There isn’t a colleague of mine I chat with regularly who doesn’t agree. Trust me, we’re not wrong.
Oh I agree. I have suspected it for some time, especially the rain guage!!!
Very nice 4!
Looks like relief will come next Monday and Tuesday when according to the NWS Heat risk map SNE is in the minor category.
Relief begins arriving Saturday.
Thanks TK !
Wordle: fail 🙂
Word never came to mind with what I had. That’s ok. Onto tomorrow.
great effort just the same! I failed yesterday. I know the feeling.
Darn. That on to tomorrow. They have been tricky lately
So example #1 of things impacting the weather for the day: A large blanket of convective debris cloud over central and eastern MA and southern NH.
While the media is already making it sound like it’s brutal this morning, the temp is in the mid 70s and dew point in the mid 60s as of 8 a.m. … Not brutal. Not even close. Yes it’ll change later. But let’s once again keep it in PROPER PERSPECTIVE. And I will continue to be the bastard from hell the media will hate because I will keep calling this out – over, and over.
🙂
I caught 5 seconds of WBZ radio this morning, just enough to hear them say how nasty it was outside “right now”. This was at 6:45 a.m. GOOD GRIEF. Had it been me on the air, I’d been telling the listeners that it was actually pretty reasonably comfortable for July 1st, but how they needed to prepare for it to be hotter and humid later in the day. Easy!
Will it never end????
BZ radio has been the same for decades…many decades
Thanks Tk . I love hot summers , bring it on . Old salty I hope you guys stay safe .
We’re trying. Yesterday wasn’t too bad all things considered.
Today will be a better test.
We’re able to cool the bedroom, dining room, kitchen, living room and bathroom with 3 ACs, total btus: 22,400 AS long as we don’t lose power, we will survive.
We’re in the group of folks who can be severely affected by this type of weather as we are both 78.
Ditto. And it is always a surprise. While I’ve always enjoyed cold more than hot perhaps due to years skiing, heat and humidity never bothered me
Never bothered me much before. I sure does now!!!!!
I know you are . Even though I like it I have always felt bad for folks like yourself who can have serious issues with heat & that’s why I always like to check on you here . Be safe my friend & take care of your wife .

Looks like any remaining debris cloudiness will be out of here soon, then BLAZING sun!!
Thanks TK. 72/69. Low was 65
Thank you TK!
Wordle: 5
Nice 5, Sue
Nice
Hopping on your car, JPD
Wordle 4
Nice 4. Welcome to the 4 car. We’ll drive for now, but I have a feeling we’ll see a 3 or perhaps even a 2 today. 🙂
77/67 here.
76/66 at Logan
Still not much sun here.
Bright sun breaking through a thin layer of clouds here
Did you send it this way. Sun breaking out now.
Wonder how much affect losing the sunshine this morning will have on the high temperature?
I’ll guess a high of 92 here today
The dewpoint and I are not on speaking terms, so I won’t guess what it might be
I’d say you go higher than 92. More like 94 or 95. We shall see.
I’ll go 95 here.
I’m always wrong so won’t be at all surprised if I am again this time
Thank you, TK.
78/68 now
Lurker since the WBZ days, but never commented. Regarding the rain, we received 1.24″ according to my gauge in Swampscott. Our temperatures and rain usually mirror Logan.
As for Wordle – got it in 5, had the wrong first letter on 4th try.
Welcome Bill!!!
Always nice to see new bloggers join and you jumped right in with Wordle!!! excellent!!!
Look forward to your posts in the future.
Yay. Another wordler. Welcome to the whw family and to the Wordle train
Welcome Bill! Happy to have you joining me in the 5 car today!
Hope to see more of you Bill!
Welcome
80 here now with dp 69
I see that dp is 70 at Norwood already!!!
I officially call YUCK!!!!!!!
77/71 here
Now 81/70
I can REALLY feel the increase in HUMIDITY today!!!
YIKES!!!!
In the caboose today but made the train! Barely
welcome to the train!!! All aboard!
Welcome aboard. Each day we have new challenges. I am happy to just get it
Just moved to the air conditioned kitchen with my lap top. Now I can’t feel the humidity. 🙂 🙂 🙂
Or certainly not as much. 🙂
I got Wordle in 4 and will be joining the crew there.
Currently 81/74 here.
74 dp!! OUCH!!!!
Nice 4. THe engineering dept is getting a little crowded. 🙂
Awesome.
82/70 here
82 at Logan with dew point 70
Thanks, TK!
83/68
85 yesterday.
JPD, wishing you and Mrs. OS the best throughout the next couple of days! Hang in there!
Thanks Capt. Yesterday was OK. Worse today, so we’ll see how it goes. ACs are cranking. Can’t get by without those.
Here’s hoping the power stays on.
We just put some A/C units in the Elevator machine roooms to keep them cool during this stretch .
Now it is 84 with dp 71
Pretty slow tempersture rise. Makes me wonder if we ever
make the mid 90s today. No matter, the DP is outrageous!!!!!
current heat index here 89.
82 and he who shall not be named is 74
So it is written, so it shall be done!
😀
I guess we’re on the rise.
Currently 86 with a DISGUTING DEW POINT = 72 !!!!!!
86/70 sat Logan and 84/72 at Norwood.
Heat index 92 here.
I actually think today may be the most humid day of the next 4.
I totally agree. YUCK!!!!
May it be.
85 and 👿 75
Oops. That’s 73
Bill in Swampscott, your comment has been approved and you should be able to continue to comment without going into moderation so long as you use the same email and username. You can change it any time, but it will go into moderation and I’ll have to re-approve. WordPress thing. 🙂
Welcome to the blog comments section!
Welcome Bill.
86/72 here in JP. Heat index 92.
86 at Noon. Doesn’t bode well for high temps in the mid 90s.
Could we still get there? sure, but will we? Usually we would be
90 by now if it were going to go that high.
I suspect we’ll be 90 by 10AM tomorrow. We shall see.
Update
87/72 here, Heat Index 94
Logan is 88, dp 70
Norwood 87/72
90/72
93/720
With the DP at 720 F, anyone would be uncomfortable! 🙂
Well I do believe that was 72
General model trends today are for fewer t-storms over the next few days which includes July 4.
Also trending a little faster with frontal passage on Saturday – though that’s not as easy to pick out. Also helps if you know which piece of guidance has the best simulation at this point. 🙂
This is nothing that prompts me to change my forecast. It allows me to leave it unchanged after reviewing all the 12z info!
I am on my way to Hampton Beach NH for end-of-afternoon until late evening. A little beach time, arcade time, dinner, fireworks, and ice cream. 🙂
93/72 heat index 101
Logan has gone to a sea breeze!!!! THere’s a big surprise!!!!
Temp down to 90 and likely to fall more. Will there be a wind shift so they can jump to 95??? We shall see.
You may recall that I mentioned local sea breeze potential at some shorelines.
They’ll need that shift back if I’m going to hit my Logan forecast if 95 today.
I’m 4 degrees off so far.
Also, most guidance no longer forecasts any 100+ readings, but media, since they already “went for it”, elected to keep it, for the most part.
Going to stick with what I’ve said about this since the beginning.
Most definitely not the “hottest in years”. Remember they also said that about a hot stretch last year? And the year before? And oh, I think the year before too. People are catching on to the antics. Meanwhile, I’ll continue to do what I’ve always done. Forecast the weather honestly and avoid the freaking HYPE bullcrap.
93/72 one degree above my guess. Will see if it goes higher
95/72. Here.
It made it. Wasn’t sure it was going to. That hot sun and warming air mass did it.
Nws has us at 95 also. Kestrel had 91.7.
BUT I had to use myself to block the sun. So maybe not as accurate as it could be.
I’ll say one thing ….its hot as …well you know the rest
SPC Outlook for Friday
https://www.spc.noaa.gov/partners/outlooks/state/images/MA_swody3.png?1782934389
96/72
We made the 96.
We did also. Just as you said we would.
96/73
32F in Swampscott. Lots of graupel. Frost warnings. Black ice likely.
he he he so, how high did it get? I presume you had the sea breeze as well, unless you are back from the coast a way.
Love this. Got room for company?
93/75 STINKEN 75 dew point!!!! Gimmie a break!!!!!
heat index 105
Fitchburge and Westfield made 97 today. I see a bunch of 99s in Northern NJ and Eastern PA and a 102 in Maryland.
What does this say about tomorrow’s temperatures here???
I honestly think 100 is still in play. We’ll see tomorrow.
Our air is coming from the west.
You mean a West wind tomorrow. Plenty hot to the West as well. (did not see any 100 degree readings, many mid-upper 90s) West wind equals down slopping which can add to the heat, although likely to reduce the stinken DP which will be nice. I still say 100 is in play (Unless there is so much debri cloudiness that lasts most of the day) We shall see.

Fitchburg
I’ve been at Hampton Beach since about 4:30 p.m. and the entire time so far it’s been in the low 80s with a steady SSE ocean breeze at about 10 MPH.
That’s nice. We were up to 96 so some parts of Boston made your prediction. Logan would have for sure, if not for the sea breeze.
Drove straight through that MCS in Upstate NY yesterday that was barreling southeast as it crossed the NYS Thruway. It was pretty wild with blinding rain, high winds and cloud to ground lightning. Passed one section right after that had debris and numerous branches strewn about on the interstate. Many cars were pulled over.
Today we arrived in Eastern PA and toured Villanova with my daughter. Beautiful campus but it was a brutal one hour walk with a heat index at the time of 106. NWS point and click for Philly has a high of 105 tomorrow (actual air temp). Softball games are scheduled for 930 and 1230. Not a good situation.
Correction – Philly hit 97 today while the dewpoint was 75 for a heat index 110. That’s probably a tie for the most oppressive heat I have ever experienced. Seems tomorrow it’s several degrees hotter but the dewpoint is lower so heat index will likely be about the same.
Looks like BDL topped out at 95 with a dewpoint of 75 and heat index of 106.
We made 96 here with dp 72, heat index 105
Later in the day it was 93 with dp 75, heat index 105
Ugh! brutal. Those games should be cancelled. Hope the hell no one falls ill.
I’d agree re cancellation
There are some nasty looking storms out there
Albany radar
https://radar.weather.gov/station/KENX/standard
Burlington Radar
https://radar.weather.gov/station/KCXX/standard
WIll any hold together to make it here later this evening or overnight?????
Those storms will likely croak before they get anywhere near SNE.
problem is in this kind of set up, they can stay together right to the coast. Likely not close to severe, but still thunder and lightning and down pours. We shall see. May have to close the windows tonight. Was able to keep them open last night.
Hit 92F. Some sea breezes today. Still a little higher than I thought.
Under / Over for tomorrow will be difficult to figure. Not sure I’ll be getting a sea breezes
I’m working on continuing my perfect fail record. 101 here for high.
81/72. Daytime is sort of ok. Not overnight too. 🙄
84.5/74 YUCK!!!
I sure agree
USA! USA! USA! 🙂
On to the next round!!!
ON TO SEATTLE!!! 🙂
Hmmmm I just posted bit don’t see it
Test
Well that worked.
I went outside to get something that was just delivered As someone who always enjoyed all types of weather, i have only one word for tonight
Putrid
Too bad it’s not five letters I would recommend it for a Wordle word tomorrow
Line of storms already looks like it’s falling apart. Darn
Nice Lighting show, and gentle thunder and 0.01”.
Warning expired
But fun to watch
Only a light rain shower here.
New post…
