Tuesday September 13 2022 Forecast (7:32AM)

Today is the lone unsettled day out of the next 5. A trough of low pressure is moving through the region from west to east, a progressive system with its warm front having gone by already and a cold front to approach and cross the area by mid evening. While we won’t see any sun for fuel today, this is a fairly strong dynamic system for this time of year so that will help trigger the showers and a few heavier thunderstorms. There will be two main rounds of activity. The first is already in the WHW forecast areas western reaches as I write this, and will cross the area during this morning and midday, with a second round coming along late in the day / early evening. Between the two can be a few isolated showers or storms, but not much. While this won’t be a widespread severe weather outbreak, a few of the storms can be strong to locally severe. Also, while much of the region will not see this, these storms can also cause torrential rainfall, low visibility, and brief road flooding, so use caution if you plan to be traveling locally / regionally today. The low pressure area exits early Wednesday, but being a pretty dynamic system, its surface low will be rather impressive and it, combined with approaching high pressure from the west, will create a gusty breeze over the region both Wednesday and Thursday as we see dry weather and a cooling trend. High pressure builds over the region late in the week with continued fair weather – cool nights and pleasant days – Friday and Saturday.

TODAY: Cloudy. Showers and thunderstorms likely from southwest to northeast this morning to midday, a few storms possibly strong to severe. Downpours may lead to brief flooding in poor drainage locations as well. Isolated showers this afternoon then a better chance of showers and thunderstorms again in western areas by late in the day. Areas of fog. Humid – dew point 60s. Highs 70-77. Wind S 5-15 MPH, gusty near storms.

TONIGHT: Cloudy with showers and possible thunderstorms west to east early, then breaking clouds and a clearing trend but areas of fog thereafter. Drying air later at night. Lows 56-63. Wind W 5-15 MPH, higher gusts.

WEDNESDAY: Sun and passing clouds. Highs 73-80. Wind W 5-15 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 50-57. Wind NW 5-15 MPH.

THURSDAY: Sunny. Highs 68-75. Wind NW 5-15 MPH.

THURSDAY NIGHT: Clear. Lows 45-52. Wind NW up to 10 MPH.

FRIDAY: Sunny. Highs 66-73. Wind N up to 10 MPH.

FRIDAY NIGHT: Clear. Ground fog patches low elevations. Lows 45-52. Wind calm.

SATURDAY: Mostly sunny. Highs 70-77. Wind W to SW up to 10 MPH.

DAYS 6-10 (SEPTEMBER 18-22)

High pressure should be in general control of the weather for the period, main center trending to the south and allowing temperatures to warm to above normal. May need to watch for showers from an approaching front by the end of the period.

DAYS 11-15 (SEPTEMBER 23-27)

Depending on timing, showers may be around with a passing frontal system to start the period, but overall pattern looks dry with a general cooling trend.

  1. Thanks TK !

    Dps near 70F along the immediate south coast. Decent storms in southern CT. Worth keeping an eye on for the immediate south coast, I think, as the line moves eastward.

  2. Thanks TK.

    A gloomy day to start. Looking forward to that “feel of fall” for the end of the week. 🙂

    Too bad it’s only going to be temporary.

    1. It always temporary.
      We don’t really get consistent weather at this latitude. 😉

      FWIW there are hints of early impressive cool shots later this month.

  10. looking at weather.us dopplar radar, can see something very small in size that is ENE of Block Island. Perhaps either very strong winds or a possible waterspout.

    1. Hopefully better this time. We’ve had our share of upgrades gone wrong in the meteorology world in the past few years!

  12. Thanks, TK.

    Nice steady light rain in Boston.

    It’s very sticky, though. I know that’s going to change soon. My guess is that we’ll have dew points in the 60s again, but won’t reach 70 until next summer.

  15. Looks like 0.26 inches so far at the Marshfield Airport.

    Yesterday had 0.05 inches, but it misted all day, the sun never appeared and everything has been wet or damp continuously for a good 36-48 hrs now.

  17. Thanks, TK.

    Sun out here. Sky looks weird here too. Last evening, shortly before sunset the sky looked amazing w/different shades of orange, red and yellow. Tried to take a picture w/my android phone but the camera showed up blurry and no colors. I have a Motorola e6, I think.

    1. Can’t go wrong with Davis Instruments, but they are a little on the pricey side.

      AccuRite is not as expensive, so it could be an alternative, but in either case, have to be careful where they are placed,.

      They are “supposed” to have radiation shields, but when in full direct sunshine, they read higher than the actual temperature.

      I would make sure I ask about how they would remedy that situation before making a purchase.

      Best of luck and I am sure others will have things to say as well.

  19. I have this sneaky feeling that the rain we got this morning will be it for the day….

    HRRR keeps in Dry from Boston South.

    We shall see!

    2. This is going pretty much as expected today. Round 1 this morning – midday, more to the south. Round 2 this evening from the west. No widespread severe.

    3. I think it was supposed to be between events. I may be wrong. CT and RI got it again this morning. It may have been Dave E who said south got it this am and storms may be more north tonight.

  22. Stacey, thanks for your message earlier! Sometimes I don’t get a chance to check my blog much during the hours of 8AM-3PM but hopefully you were able to get your errands in! You should be all set for the rest of the afternoon if you’re still out there. 🙂

  23. Clouds.

    We have not talked about clouds much. But basically I kind of knew as we all do that there are high altitude, mid altitude and low altitude clouds. Over time, I have seen clouds bucketed into 6 categories, 10 categories, 14 categories, and I believe the World Atlas of Clouds (I don’t have that name quite right) might list 100 types.

    What I am wondering from those of you in-the-know, is there an accepted categorization of clouds for the USA among meteorologists?

    1. Basically the “textbook” definitions apply and we all generally use the same that you would see in the “atlas”. But we tend to not mention the sub-categories that often at least in media as it would just confuse a lot of folks. Keeping to the basics with some added detail is probably the best way to go about it. But knowing all of the different types / categories is fascinating for the “weather geek”. 😀

    2. Todays clouds were eerie. And when I just returned from my appointment were pitch black over mendon and Milford. I didn’t see anything on radar

  25. 0.16 inch here in Back Bay. At least it was something. Never rained hard. Perhaps there will be some more rain tonight, but I’m skeptical.
