DAYS 1-5 (AUGUST 10-14)

People talk about the lazy days of summer. We’ll have a lazy weather pattern this week, making a transition from the heat and humidity that starts the week to cooler and less humid air to end it, with the process taking place over about three day’s time. First, offshore high pressure pumps heat and humidity into the region for the classic summertime feel today and Tuesday, and while the vast majority will not see anything rainfall, there is a risk both days of a few isolated afternoon showers and thunderstorms, the slightly higher risk of the 2 days being today. The transition out of this air mass begins Wednesday, but only in the form of a better chance of showers and thunderstorms, favoring areas north and west of Boston, during the afternoon and evening ahead of an approaching cold front while we remain in the hot and humid air mass. This very slow moving front will take all day to cross the region Thursday, the most unsettled day of this period, when additional showers and thunderstorms are possible, with activity tending to favor areas along and southeast of the I-95 belt by later in the day. The front will finally have pushed through by Friday, barely, still sitting near or just off the South Coast and Cape Cod, where additional showers are possible during the morning hours. Otherwise, Friday will see a clearing trend with drier and cooler air arriving.

TODAY: Some fog and low clouds near the South Coast early, otherwise mostly sunny to partly cloudy. Chance of isolated showers and thunderstorms in the afternoon. Humid. Highs 86-93, may turn cooler some coastal areas. Wind SW up to 10 MPH, with coastal sea breezes possible.

TONIGHT: Partly to mostly clear. Patchy fog in low-lying areas. Humid. Lows 65-72. Wind SW under 10 MPH.

TUESDAY: Mostly sunny to partly cloudy. Slight chance of isolated showers and thunderstorms in the afternoon. Humid. Highs 89-96, may turn cooler some coastal areas. Wind SW up to 10 MPH, with coastal sea breezes possible.

TUESDAY NIGHT: Partly cloudy. Humid. Lows 67-74. Wind SW under 10 MPH.

WEDNESDAY: Partly cloudy. Scattered showers and thunderstorms in the afternoon, favoring areas near and northwest of I-95. Humid. Highs 88-95, cooler Cape Cod. Wind SW 5-15 MPH but can be variable and stronger near any showers and storms.

WEDNESDAY NIGHT: Variably cloudy. Scattered showers and thunderstorms possible early. Patchy fog. Humid. Lows 66-73. Wind SW up to 10 MPH.

THURSDAY: Variably cloudy. Scattered showers and thunderstorms possible anywhere late morning to early afternoon then favoring areas near to southeast of I-95 remainder of afternoon. Humid. Highs 82-89. Wind variable up to 10 MPH but can be gusty near any shower and storms.

THURSDAY NIGHT: Mostly cloudy. Chance of showers favoring the MA South Shore and MA / RI South Coast. Patchy fog. Humid. Lows 60-67. Wind variable up to 10 MPH.

FRIDAY: Mostly cloudy start with a chance of showers near the South Coast, otherwise increasing sunshine. Less humid. Highs 78-85, coolest coast. Wind NE to E up to 10 MPH.

DAYS 6-10 (AUGUST 15-19)

High pressure centered north to east of the region over the August 15-16 weekend should be strong enough to keep it rain-free although some cloudiness is possible at times, while it’s seasonably mild to warm with low to moderate humidity. A frontal boundary and disturbance brings a shot at more widespread shower activity August 17 before a drier but warmer to hotter westerly air flow arrives later in the period.

DAYS 11-15 (AUGUST 20-24)

High pressure will be the main controller with mostly dry weather and temperatures running above seasonal averages heading into late August.

  5. Thanks TK and SAK
    I hope that weekend forecast holds. If it does to me that could be the best weekend of the summer if you are like me and not a fan of the heat and humidity. If it is going to be this warm let us set some records. At BDL were up to 31 days 90 or higher for 2020. The record is 38 set back in 1983. Let’s break that record. If the forecast holds we should be up to 34.

    1. Wow! I actually thought that we were running behind on temp
      rise. Oh well.

      The longer nights and a bit lower low temperature coupled with lower sun angle takes its toll. Ahh climatology.

      I keep telling my wife that climatology will take over
      and these hot days WILL have to cease. Average high temperatures are already on the way down. I think it is down to 81 or 80 for Logan.

      1. Agreed ! I can see the effects in the evening with the sun dropping below our tree line, allowing our AC to maximize starting around 6:30 pm now, compared to waiting til 7:30 or 8 just a few weeks ago.

        1. Oh yeah, for sure. It is really noticeable.

          My Davis Equipment is in the shade longer now.
          I have received the radiation shield. Haven’t gotten around to installing it just yet.

  8. The gradient is weak, Logan has West wind at 7mph.
    Wouldn’t take much to flip that wind on shore and end
    the “heat wave” for Boston.

  14. As we talked about above, the shortening days and lower sun angle in the coming weeks will help the cause a bit.

    La Niña, pattern persistence, drought and various outlooks give a greater percentage chance that above average temps will continue into the fall.

    Against our climatological highs, which I believe is 77F to start September and 67F to end and considering that a well above average day is +10F to maybe +15F, it’s reasonable in a warm surge to hit or exceed 90F through a good part of September, than it really becomes something extremely noteworthy to accomplish that by month’s end.

    1. LOGAN made 91 before.

      Latest Raw Observation

  16. – 11 out of the last 24 days (since July 18th) have been 90F or higher at Logan. (Logan, including today, now has 12 (90F) days. It was 92F on June 20th.

    – Another 16 days have had highs of 85F to 89F since June 18th (53 days)

    – Thus, during the last 53 days, 28 days have had high temps anywhere between 85F and 95F.

    – Of the 25 days in the last 53F, that had highs less than 85F, 19 of those 25 had high temps < 80F.

    – In contrast ……. 1,000 ft Worcester has only had 10 days during the same 53 day period with high temps < 80F.

    In summary, this year ………… fairly consistent summer temps began June 18th and the hottest stretch of the summer has been July 18th to current (and counting).

  18. The Weather Channel is reporting that a derecho is in progress, exiting eastern Iowa and about to enter northwestern Illinois.

  23. 4 runs or so, in a row on the euro of a decent cool shot in the long term (7 to 10 days) from now. I think TK mentioned this possibility a few days ago.

    Different high location on this projected cool dip. Down thru the Great Lakes instead way to our northeast into the Maritimes.

    Now, the question is, will this hold as it comes into the medium and then short range ??

    1. Enjoy Lake George JJ! Where are you staying? As I think you know, I grew up not too far from there. Really nice area.

  25. Crazy sun shower right now in Manchester CT. I call it a “ shower” but it has been absolutely deluging for 15 minutes. The gutters of the roads look like rivers. And all the while, the sun has been out in full force. Big rainbow off to the east now. One of the odder weather phenomenons I have experienced!

  26. I’m watching cnn for trumps briefing. He left mid sentence and reporters were told White House on lock down. It’s just breaking so no idea how accurate

    1. He’s back at briefing. Someone was shot outside of WH by secret service. They will fill us in later

  27. Wind gusts to 106mph in Marshall Iowa from that derecho that CF posted on above. One third of the state of Iowa is without power as well as many in northern Illinois.

    Ironic as there are utility crews here in CT from that area helping restore power to some shoreline towns that still have no power from Isaias.

  31. I second that Vicki. I hear lots of thunder that seems to be increasing, no wait thats my son playing Fortnite. Seriously though the storm is on my doorstep in Brimfield at the moment moving very slowly eastward. I hope I get some rain out of this, but the theme this year is to have them dissipate right about where they are now. Fingers crossed.

    1. Hahahahaha. We should get my grands and your son connected. At least I think that is what they play. But your comment has me laughing out loud.

  33. New weather post is up… Please note that the C-19 post and the weather post today are in reverse order from how they are typically posted.
