Saturday July 31 2021 Forecast (8:57AM)

DAYS 1-5 (JULY 31 – AUGUST 4)

It may be mid summer still, but this final day of July has started out almost with a hint of fall in the air with a nice cool air mass in place and a gusty breeze picking up again. The breeze will settle back down and the temperature will climb enough to remind you it’s still summertime, though it will be a cooler-than-normal day, but nice and dry for enjoying outdoors. A wind shift to south brings in more humidity and eventually we see more clouds on Sunday as two systems approach the region, a trough to the west and low pressure to the south. It looks like our greatest chance of rainfall comes Sunday night, but will be limited as we are basically between the two disturbances. The southern low brings the best chance of rainfall to the South Coast region while the western trough brings a shower threat to areas mostly north and west of I-95 Sunday night, but that trough line will swing through the region Monday and still may produce a brief shower or thunderstorm as it passes by. Otherwise Monday’s trend will be for slightly drier but seasonably warm air. High pressure is going to become more established off the US East Coast in the early days of August and by Tuesday and Wednesday we’ll find ourselves in a south southwesterly air flow of warmth and somewhat higher humidity, but likely absent of any rainfall.

TODAY: Mostly sunny to partly cloudy. Highs 72-79. Dew point middle to upper 40s. Wind W 5-15 MPH.

TONIGHT: Clear except fog patches forming over interior lower elevations. Lows 52-57. Dew point upper 40s to lower 50s. Wind SW under 10 MPH.

SUNDAY: Mostly sunny morning. Partly sunny afternoon. Highs 75-82. Dew point rising toward 60. Wind S 5-15 MPH.

SUNDAY NIGHT: Mostly cloudy. Chance of showers and possible thunderstorms. Areas of fog. Lows 61-68. Dew point lower to middle 60s. Wind SW 5-15 MPH.

MONDAY: Partly sunny. Chance of a brief passing shower or thunderstorm. Highs 77-84. Dew point near 60. Wind W up to 10 MPH.

MONDAY NIGHT: Mostly clear. Lows 61-68. Dew point near 60. Wind variable under 10 MPH.

TUESDAY: Mostly sunny. Highs 77-84, coolest coast. Dew point near 60. Wind variable up to 10 MPH with light coastal sea breezes.

TUESDAY NIGHT: Partly cloudy. Fog patches forming. Lows 62-69. Dew point lower 60s. Wind S up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 76-83, coolest South Coast. Dew point middle 60s. Wind S 5-15 MPH.

DAYS 6-10 (AUGUST 5-9)

A southerly air flow and increased tropical moisture brings a better chance of shower activity during the August 5-6 period before high pressure strengthens and keeps us warm and fairly humid but with mostly rain-free weather for the August 7-8 weekend and on through period’s end.

DAYS 11-15 (AUGUST 10-14)

Transition back toward more westerly flow into the middle of August probably means another round of unsettled weather somewhere during this period, favoring early to mid period. No major temperature departures from normal are indicated at this time.

  1. Thank you, TK. Dropped to 47 around 4 am. Warmer now but lower DP mean my fire pit on deck is turned on. It is lovely. I remember many August…yes not august for one more day….mornings and evenings like this.

    1. If we’re not in one of those southerly flow muggy patterns, we certainly can be open to those early cooler days in August. I think we’ll have a bit of both for August 2021. 🙂

    1. As always, that will be a matter of opinion.
      I’ve already been seeing my share of social media posts complaining about it being too cold.
      I just laugh that stuff off these days…

      1. Absolutely.

        I´m probably guilty of being extra thrilled with today´s weather because I´m outside readying our camper for our next trip.

        If I was at the beach, I might have written top 10 or 15 🙂 🙂 🙂

    1. Lead singer just had a birthday recently.
      Saw them in 2018 (co headlined with Counting Crows, whose singer has a bday tomorrow). Great show by both.

  2. Model trends …
    Splitsville tomorrow night – some wet weather, but not much.
    Monday still maybe a trough-induced shower but mainly dry.
    Tue & Wed look dry & seasonably warm.
    GFS trend is to slow down the onset of the wet weather threat and keeps Thu mostly dry and makes Friday the wet day.
    Next weekend into the following week the trend is for a weak Bermuda High with above normal temps (but not major heat) and higher humidity, but limited rain chances.

  3. Hi everyone!

    I know it’s on Saturday but what are early thoughts for next Friday night?

    Going to a concert at Fenway (I think there is a show almost every night next week there!). Last time there was thunder and lighting and we had to be evacuated from our seats on the field. Luckily the rain stopped before the main act but it sure was steamy. Not sure why I chose to go again! I guess I’ll have to bring a poncho and a mask and hope for the best and prepare for the worst. Which has been the ongoing theme for the past 18 months.

    1. Well, as of now, the period of Thu Aug 5 & Fri Aug 6 are the higher risk days for some wet weather.

      Too soon for timing & details, but it looks like a lot of weather watching will be needed leading up to this.

  4. The ribbon of wet weather thats projected along the East coast for a few to many days …..

    Question: Is the jet stream too strong or can something tropical develop within that boundary/old washed out front ?

    1. Always have to watch a set-up like that for tropical development. I don’t think it’ll be that pronounced along the coast for that long though.

  5. Thank you, TK.

    There have been a few really nice July days this year. Today tops them all, and may be the nicest summer day of the year. I realize this is a subjective call.

    TK, if you have any weather pattern projections for London, UK, starting next Friday, I’d greatly appreciate it. I’ve begun to pack. My daughter just told me, “Dad, no need to bring shorts, but a sturdy umbrella will come in handy.” I responded by saying, we’ll need to go to James Smith for that: https://www.james-smith.co.uk/

    1. Early call: Starts out wet and on the cool side Friday with another surge about Sunday. Following week the trend is drier and milder.

    1. Not a lot of detail there but just a general idea. Remind me and I’ll check it when we get a bit closer.

      1. General idea is good. Thanks, TK.

        It’s a VERY London summer forecast from what I’ve gathered. Some off and on rain shower days, a couple of gray days, and a day or two with an occasional glimpse of the sun, upper 60s to around 70. I’m mostly packing for relatively cool and possibly a bit wet weather. It’s fine. I get to see my daughter, and that’s what matters.

  6. Sports note: Sox are in trouble. They’ve been great as comeback kids, but that’s not sustainable over the entirety of a season. They don’t lead in enough games, even when things were going well. They needed help at the deadline and got almost none (Even Kyle S won’t be available for several more weeks! and he’s kind of position-less). All their competitors got help, in fact, a lot in some cases.

    1. You brought back memories of the 1967 impossible dream team and the come back kids….was it 2013?

      I always said when they do well first half of the season, they fall apart in the second. I haven’t paid attention in years so maybe that no longer holds true

    2. Let’s hope Chris Sale can make a huge comeback on the mound, for starters. If he can go 7+ innings and keep the opposing team 2 runs or less, watch out!

      Also, didn’t the Sox get a couple of good relievers from the NL?

      It would be a crying shame if they don’t at least make the postseason this year.

  7. So the Sox lose a few games and are only 1/2 game out of first and everyone is in panic mode? Funny. 🙂

    And yes, Sale will be back. Time for everyone to take a chill pill (or two). We go through this all the time and everybody reacts the same way every time. It’s kind of amusing when it comes down to it. I love watching the FB freak-outs even more. 😉

    Just enjoy the season. They can’t win every game 100-0. 😉
