Tuesday July 21 2026 Forecast (7:03AM)

DAYS 1-5 (JULY 21-25)

A trough of low pressure will traverse the Northeast between today and early Thursday, with its associated surface low pressure area passing to our north. A warm front will approach the region today with thickening cloudiness and eventually showery weather later today through most of tonight, including some embedded heavier thunderstorms. The greatest opportunity for heavier rainfall appears to be mostly from the I-90 belt southward, but I am not expecting any severe thunderstorms to occur. We’ll see that activity exit off the coast by morning with a mix of sun and clouds and higher humidity Wednesday. As a cold front approaches, we’ll see the opportunity for showers and thunderstorms in one or two clusters or lines in the afternoon, although coverage may not be widespread. The character of the storms will be determined by how much clearing / sunshine there is to help destabilize the atmosphere and fire up the storms. Once the storms form, they can at least partially dictate their own motion through outflow boundaries and such features. I do think the majority of the activity by late afternoon and early evening will be near or east of I-95 as the frontal boundary should advance far enough for that to happen, and then anything that remains should fade rather quickly with the setting sun. However, the front will be slowing and still over southeastern MA / RI into Thursday morning, when additional showers may occur. After that, it pulls offshore. So the trend is for fair weather to return on Thursday then continue into the start of the weekend as high pressure builds in, providing pleasant weather including lower humidity.

  1. Good morni g and thank yiu TK

    67 up from 74

    Ocean: 64

    Wordle: 3

    Last night on ch 10 they were spewing doom and gloom about severe weather for today. I told my wife they were full of shit. This crap has to stop!!!!!

    1. We are kind of in marginal risk .. but I don’t think the full potential will be realized.

      And the news direction will make the stations focus on even the slightest risk so you’ll hear harder hits on local media. Gotta have something to “alert” for because it gets people to watch.

      Again, I don’t agree with the practice either, but that’s why it’s done.

      1. Understanding that the Mets and news teams do not support this either. It’s a mandate from management.

      1. When I was dating my wife, she lived in Boston and I lived out in the boonies in Millis.

        Anyhow, One evening I was coming to pick her up and she was on the porch with neighbors and one of the neighbors (same age) shouted out to me: LOOKS LIKE RAIN BY CRACKY!
        making fun of the fact that I lived out in the country and then
        he said STEP ON ANY COW FLAPS? on the way

        All in good humor!!! 🙂 🙂 🙂

  2. Quite feisty thunderstorms just north of NYC.

    On the warm front, near the truly tropical air. I am sure they are being closely monitored down there for flash flooding and possible rotation.

    1. Nice 5. No issues with 2nd letter. It was the 3rd letter that prevented me from getting it in 2. 🙂

      Not sure where the rails will take us. How about out to the Berkshires?

  3. Looking at radar the initial outbreak of storms seems a bit slightly north and west of what happened Saturday when NYC and Long Island got pounded. Will be interesting to see how this evolves next few hours and will this mean more rain for areas further west and north of South Coast.

  4. Thanks, TK!

    Trying to type and radar watch with dilated eyes! 🙂
    Comprehensive eye exam this afternoon.

    Flash Flood Warnings along the Connecticut coast!

        1. You as well? that is 3 of us!!! WOW!!

          My report was excellent!!! I don’t need cataract surgery at this time! YAY!

      1. Thanks, Vicki! My ophthamologist has been monitoring my eyes for an enlarged optic nerve and possible glaucoma for years. All is well and stable from today’s exam!

    1. It says moderate risk, but looks like they are only expecting
      EF0 or EF1 ratings on any that occur. That is a good thing,

    2. I wonder IF this will get extended Eastward. I don’t think so, but will keep an eye on it just in case.

  5. One day late with this – some weather history for Washington DC.

    July 20 1930, Washington DC matched its all time record high of 106F, previously set on August 6 1918.

    It has never been reached since.

    105F has been hit 3 times: 7/10/1938, 8/17/1997, 7/7/2012
    104F has been hit 5 times: 7/21/1926, 7/9/1936, 7/16/1988, 7/29/2011, 6/29/2012

  6. Here we go! Wind gusty and dark skies – some thunder in distance and a few flashes of lightning. Rain coming down but nothing too bad

  7. Call me crazy I’m heading down to Sarasota tomorrow 7:05 flight ✈️ I’m hoping for no weather delays from PVD. Ground crew will not load cargo on the plane if lightning ⚡️ is in the area. Beach conditions will be much better tomorrow and Thursday. Gulf Of Mexico water temperatures around eighty seven. I went for a swim along our south coast yesterday in Narragansett water temperature was about seventy one not too uncomfortable.

  8. Got an alert on my phone for torrential rain and street flooding. Let’s see if it actually materializes. Looks to me as if some weakening is beginning to occur.

      1. Rumbling here.

        Moderate rain, no torrents, yet.

        Humid, but almost a bit cool with the SE breeze. Switching to AC later when the 70F+ dps move in.

  9. .68 inches in less than an hour with more to come – feels like a drought busting month in this area of state
