DAYS 1-5 (JULY 23-27)

A hot weekend is ours. No way around that, so find ways to stay cool if you can! The humidity will be a factor as well, less so today for much of the region with readings under 70, but some 70+ readings are present near the South Coast, and these will spread northward across most of the region for Sunday. You’ve heard talk of high temps near 100 for some places Sunday. While the temps may certainly get way into the 90s, a place like Boston is not likely to reach the century mark with a higher dew point and a wind blowing from the south and southwest, as is expected. The metro area gets its hottest weather when the dew point is lower and the wind is more west or even west northwest, so while the wind direction may prevent the higher temperature reading, it will help bring in the oppressive humidity. So either way you look at it, it’s going to be a hot weekend, though we may get through it without breaking any record temperatures – though a few may be challenged Sunday. I also think the thunderstorm threat will be absent as we are under the influence of weak high pressure and the warmer atmosphere aloft is a stabilizing influence. Things start to change later Sunday night and especially Monday as we bring a cold front into the region. Right now, the timing of this frontal boundary remains a little in question, and knowing this will help determine when thunderstorm threats are and how many rounds of them we may see. Keep in mind as you see the detailed forecast for that day that fine-tuning will be done and more detail added during the next couple days. Whether or not the 90+ temperatures are reached on Monday will depend on timing of front and amount of cloud cover. So Boston is a lock for a 6-day heatwave (through Sunday) as I see it, but not necessarily for a 7-day. Their record is 9 days in 1912, at which time the readings were taken in the city and not the current airport location. The airport location has recorded a few 8-day heatwaves (1944, 1994, and 2002). So those records are safe, because Tuesday’s temperatures (and dew points) will be down considerably behind that front as high pressure moves in with great summer weather as we head toward the middle of next week.

TODAY: Sunny. Highs 90-97, cooler South Coast. Dew point ranging from near 60 southern NH and northern MA to around 70 at the South Coast. Wind W 5-15 MPH.

TONIGHT: Partly cloudy. Patchy ground fog. Lows 68-75. Dew point middle 60s southern NH and northeastern MA to around 70 elsewhere. Wind SW up to 10 MPH.

SUNDAY: Mostly sunny. Highs 92-99, hottest in the Merrimack Valley region, cooler locations South Coast. Dew point lower to middle 70s, highest South Coast. Wind SW to SSW 5-15 MPH.

SUNDAY NIGHT: Variably cloudy. Chance of showers and thunderstorms, mainly late at night and favoring areas west and north of Boston. Patchy fog. Lows 72-79. Dew point 70+. Wind SW 5-15 MPH.

MONDAY: Variably cloudy. Chance of showers and thunderstorms, favoring morning to mid afternoon hours. Highs 85-92, cooler South Coast. Dew point 70+. Wind SW to W 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Patchy fog mainly interior lower elevations. Lows 65-72. Dew point falling through 60s. Wind W 5-15 MPH.

TUESDAY: Mostly sunny. Highs 82-89. Dew point upper 50s. Wind W 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Lows 60-67. Dew point 50s. Wind W up to 10 MPH.

WEDNESDAY: Mostly sunny. Highs 81-88. Dew point 50s. Wind variable up to 10 MPH with light coastal sea breezes.

DAYS 6-10 (JULY 28 – AUGUST 1)

Heat and humidity return for July 28 along with a chance of showers and thunderstorms with the approach and passage of a cold front. An area of high pressure should bring dry and seasonably warm weather July 29 on with some increase in humidity toward the end of the period as the high center sets up to the south of New England.

DAYS 11-15 (AUGUST 2-6)

Higher humidity spike early in the period including a chance of showers and thunderstorms, then drier air and seasonably warm weather following.

  5. BOSTON — With the majority of the state currently experiencing elevated temperatures and forecasts predicting little to no meaningful precipitation, Energy and Environmental Affairs (EEA) Secretary Beth Card today declared a Level 3-Critical Drought in the Northeast and Central Regions of the state. The Southeast, and Connecticut River Valley Regions will remain at a Level 2-Significant Drought, and the Cape Cod Region will join the Islands and Western Regions at Level 1-Mild Drought. As outlined in the Massachusetts Drought Management Plan, a Level-3 Critical Drought and a Level 2-Significant Drought calls for the convening of an inter-agency Mission Group, which has already been convened, to more closely coordinate on drought assessments, impacts and response within the government. Additionally, a Level 1-Mild Drought recommends detailed monitoring of drought conditions, close coordination among state and federal agencies, and technical outreach and assistance to the affected municipalities.

    2. Less of sun’s energy used for soil evaporation, more going to heating of the air.

      Perhaps will translate to 1-2F higher temps than model projections.

  8. Thanks TK !

    I think we got down to low-mid 60s last night up here, it was the first comfortable overnight in several days.

    Warming up quickly this morning.

    Quick peak at 00z GFS projected 850mb temps.

    The “coolest” day I could see was 10-12C, with a lot of days in the 14-18C range. Lots of very warm weather ahead, after this heat wave, with periodic hot days mixed in.

        1. Totally agree and we touched 95 yesterday. That added a new level to the heat. My perfect Summer time high temp is 85.

  9. Logan wind NW at 6 mph.
    Will a potential sea breeze keep Logan from making 90? Will be close, but at the rate temp is climbing, they may make it prior to any sea breeze.

  10. How high will it go ?
    This is the hottest the house has been in the AM so far this Summer.
    I am not at my computer but rather sitting in the kitchen in AC and using phone.

  11. As I take my Saturday morning summer walk It’s quite nice out here with a temperature of 83 and a dew point of about 64.

      1. Hahahaha. Yep…my comment was a bit tongue in cheek. Doesn’t take much to amuse me 😉 How is Mrs OS? I understand her feeling trapped. I at least have more than two rooms but oddly the only time it is difficult for me to go out is in summer…..ironic eh?

  15. Logan has made 90, so that makes it a 5 day heat wave. They now have a 10 mph SE sea breeze. No mid to high 90s for Logan, Unless there is the big 5 pm wind shift.

  17. I’m off to Fenway again this afternoon, why I have no idea. Between the heat and the pathetic performance last night, I’m expecting a miserable afternoon. Of course, I have a friend in town that is a Blue Jays fan accompanying me to the game, but he hates the heat more than I do. At least we’ll be in the shade – we have front row right behind the Blue Jays dugout.

  18. Sooooooo lawn question. We stopped watering. Drought is too bad to pour water into a lawn. Do we still put down treatments such as grub and just water that in??

    2. Dormant lawn still needs regular watering or it will actually die. In terms of products, yes, most need at least 1/4” water to activate ingredient(s). One solution I’ve done if I absolutely need to add products is use liquid products.

        1. Not as much if actively growing. Infrequent (once per week) but deep watering 0.5 to 1.00”.

          1. Thank you. I always appreciate your lawn advice. With any luck we will get rain enough to cover but keeping track is easy. And timing grub and other stuff can hopefully be done around rain.

            1. Do u have active grubs? Usually this time of year the beetle form of them are busy laying eggs that will hatch into young grubs late summer/early fall. That’s when u want to put down the Bayer Advanced 24hr killer. If not and it’s for preventative it’s too late for a Scott’s Grub EX type stuff.

              1. And again. Much appreciated. We do not have active grubs that I see but the four skunks were dining on something so we suspected grubs. I’ll wait for Bayer

                1. It can’t hurt to put down the Bayer now if ur worried about it. Could be anything the skunks art trying to get at.

  19. 97

    That’s the temperature right now, not the number of runs Toronto will score this afternoon.

    1. I love the heat old salty but I sincerely feel bad for the folks who do not do well in it like your wife , hope it gets better for her soon buddy .

          1. Sorry I would think that since 90 is 7 degrees above the average high. A cold snap would be 3 or more days below 35 degrees for high temperatures?

            1. Heatwave has been around for a long time as a term. Since people pay more attention to 90+ and don’t have such a solid threshold for considering cold, trying to define a specific temperature to apply to a cold snap would not work at all. There is a certain amount of psychology tied to weather.

              You’d end up getting arguments about 35 vs 32 vs 25 vs 20 vs 0. Where as most people are not going to argue 90 as a threshold for uncomfortably hot (for the average person).

              1. Perfect.

                The term cold snap is perfect to me as it isn’t defining a period or temp….just cold.
