DAYS 1-5 (JUNE 26-30)

This five-day forecast period covers the home stretch of June. It starts today with a humid day. A warm front crossing the region this morning brings a band of widespread showers. A rumble of thunder can’t be rule out through mid morning from the South Coast to South Shore of MA before the rain exits. During the hours from mid to late morning until late in the day we see warmth and humidity with a sun / cloud mix. The amount of sun overall will determine how much we can destabilize the atmosphere to aid in the development and sustaining of showers and thunderstorms that will be triggered by an approaching cold front as low pressure moves across southeastern Canada. The greatest potential for strong to locally severe storms will be north of I-90 between 4 p.m. and 8 p.m., and this afternoon it becomes a “now-casting” situation to monitor what goes on. This activity will fade as it tracks to the south and east and loses support. If any storms do become severe, wind damage is the primary threat, but an instance of hail 1 inch or greater in diameter is not impossible. The cold front goes through tonight but temporarily slows near the South Coast as a weak wave of low pressure moves west to east along it. This can hold the shower chance near the South Coast into Saturday morning with some cloudiness but rain-free weather elsewhere. These clouds then move out but as they depart, we’ll see diurnal cloud development and a couple of these could grow enough to produce a spot shower or thunderstorm Saturday afternoon. These would be isolated with most locations missing out. Areas that did see them would only be wet for a brief time, but could experience a downpour. So do keep an eye out if you have outdoor plans. We repeat this chance on Sunday, but to a slightly lesser degree with again most of the region just seeing fair weather. Temperatures this weekend will be seasonable with humidity at comfortable levels. Coastal areas will be a bit cooler each day with a tendency for onshore winds. High pressure provides generally fair and warm weather Monday and Tuesday, however during Tuesday we will have to keep an eye out for a disturbance in a northwesterly air flow aloft that could bring a passing shower or t-storm to some locations. At day 5 the confidence on this detail is low.

TODAY: Cloudy through mid morning with showers and the slight chance of a thunderstorm west to east. Partly sunny late morning through mid afternoon. Mostly cloudy late-day with showers and thunderstorms likely, particularly north of I-90 including the potential for a strong to severe storm. Highs 78-85. Dew point peaking in upper 60s. Wind S to SW 10-20 MPH, higher gusts possible.

TONIGHT: Partly to mostly cloudy. Any early showers / thunderstorms southeastern areas will move out. Patchy fog. Lows 60-67. Dew point near 60. Wind W up to 10 MPH.

SATURDAY: Lots of clouds morning to midday including the chance of light rain near the South Coast, then a sun / cloud mix including the slight chance of a pop-up afternoon shower over inland locations. Highs 75-82. Dew point falls below 60. Wind variable to E up to 10 MPH.

SATURDAY NIGHT: Mostly clear. Fog patches lower elevations. Lows 55-62. Dew point lower to middle 50s. Wind calm.

SUNDAY: Sunny start, then a sun / cloud mix. Slight chance of a pop-up shower or thunderstorm during the afternoon. Highs 77-84, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.

SUNDAY NIGHT: Clearing. Lows 58-65. Wind variable up to 10 MPH.

MONDAY: Sunny to partly cloudy. Highs 78-85, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.

MONDAY NIGHT: Mostly clear. Lows 60-67. Wind variable to W up to 10 MPH.

TUESDAY: Sunny to partly cloudy. Remote chance of an isolated shower or thunderstorm. Highs 80-87. Wind W 5-15 MPH.

DAYS 6-10 (JULY 1-5)

General pattern features a northwesterly flow aloft, which is a seasonably warm pattern here with higher heat held off to our west. This pattern is mostly dry, but also features the chance for a few showers and thunderstorms to ride over the top of the ridge to our west and southeastward across New England. Sometimes these can be remnants, other times stronger and more organized. With this period of time leading up to and including the holiday weekend, there are many outdoor plans so it will be important to pay close attention to the weather each day regarding plans and travel to and from events.

DAYS 11-15 (JULY 6-10)

Some general pattern configuration expected – northwesterly flow. Some temperature variability including the chance for a hotter day or two, but also the chance for a few passing showers and thunderstorms. Dry weather the majority of the time.

  1. A little insight on the heatwave in France…

    Media has made it sound like all of Europe is baking. It’s not.

    If you recall in a recent discussion I made, the tendency this spring was for some late-season omega blocks. One such has been in place in southwestern to central Europe and the adjacent Atlantic. The ridge portion of this block allowed Saharan air to move northward into France, which sat under the peak ridge position. And there you go.

    Also not spoken of in general media, because it’s a little beyond the science understanding of the general public (but wouldn’t be if they’d actually take the time to explain it): Changes in regulations in Europe have reduced low level pollutants, and therefore reduce the amount of low level reflecting cloud cover, and therefore increased the amount of solar radiation that reaches the surface, hence adding to the intensity of heat that would have otherwise been modified by stratiform cloud layers.

    Funny how you can understand things better if you apply and explain the science and leave out the sensationalism.

  6. Although I had the impression from reading the heatwave was more localized, I had read about solar brightening a while ago. I save this stuff in my iPad notes.

    This article was from a while ago. I’ll see if I can find updates.

    Aerosols: are SO2 emissions reductions contributing to global warming? | Copernicus

  13. Rain is done here. Now how much sun do we get????
    Will we get storms here or not?

  17. (Wanted to repost the post I put on the last one ( my morning, you’re late evening lol.)
    As a marine and environmental scientist that studies global change ecology ( climate change, diseases, invasive species, pollution etc impacts on the environment) and restoration in the face of these stressors.

    Climate change is real no question on that.
    We have seen an increase in extremes. (yes there are more people posting and showing this but its also happening more)

    Normal climatic patterns are becoming “more extreme”

    Many of the predictions made in the 2000s/2010s have come true to an extent. (from the actual scientists).

    Humans have a major impact on their environment not even talking about climate change.
    We are causing harm at local, regional and global scales.
    Successful conservation and restoration has shown what is possible if people work together as well

    If we stop harming the environment, we have seen how quickly mother nature can heal herself.

    Humans has a major impact on our climate and we been doing it since the villages of North Africa where they built trees around their villages for multi-purposes. One for Food, one for shade, it made the villages cooler, it protected them from grass fires but also its been shown that it also increased rainfall for them. Complete change of the local environment.

    There is no way our burning of fossil fuels does not impact the environment.

    The ship regulations where change a handful of years ago, and could have been linked to the temporary warming of northern latitudes shipping routes (connected to what TK is speaking of above)

    There was a recent study put out last year that showed that we actually saw a dip in CO2 emissions. We are seeing increased green tech being used over the past 5 years. Now imagine if these where given the tax breaks, these where given the millions that oil and gas get from our taxes? How much quicker this would go?

    As I have continued in the field, I have cointinued my distain for a certain side of the aisle way more than the other but both sides have issues and not all members are responsible.
    Most people agree we need to take care of our planet and want this, but we have people with money and power that get in the way.
    There is a reason why they where trying to take out the oceanographic monitoring system and it wasn’t to replace it with something better.

    Regardless of if you think climate change is human caused or not, there is so much we can do that will make this planet better if we just listen to the facts and act on them.

  21. Starting to see a little sun. I am not expecting any thunderstorms where I am today. Middle end of next week will see if some ridge riders happen that could produce some thunderstorm activity.

  22. Thanks, TK!

    69 with 0.05″ in the bucket.

    3 pm World Cup match at Gillette today.

    I haven’t watched every match, but I believe there’s been only one or two matches affected by weather in this soccer tournament. The match in Philly was delayed and the stadium was evacuated for the threat of lightning. I think a game in Toronto was played in rain earlier on. Other than that, the weather has been great! I know that some of the venues are domed-stadiums.

    The weather heats up across the country next week, so we’ll see what happens with matches in the knockout round!

    1. In Peru, lightning struck during an amateur match, knocking out 8 players and tragically killing 1 of them.

      The video below shows the event.

      Warning: THIS VIDEO IS VERY GRAPHIC!

      A similar event occurred in the Republic of Congo circa 2000. I believe there were more injuries and deaths in that event. All I can remember is that it was horrifying.

  25. Often times when there is a thunderstorm threat we’re posting at just about the same time. Will see if that happens if that happens next week. I have a feeling there will be at least one thunderstorm threat.

  29. A few indications of what may be the early stages of a supercell thunderstorm that may track from VT into NH and potentially northeastern MA between 5 p.m. and sunset.

  30. I saw something the other day that all the tornadoes so far in New England have been in Vermont with three tornadoes.

  31. Thanks TK.

    Always so hard to pull off for SNE (thankfully), but if ever there was a pattern to bring a true high end severe MCS/derecho event through the region, the next 14 days are it. A classic “ring of fire” pattern with this high amplitude ridge west of the region. Several opportunities will be on the table…

    Also potential for a couple of very hot days in SNE over the next couple weeks, although the core of the heat definitely stays west. A lot of notably “high amplitude” patterns globally right now, obviously relating to the European heatwave as well.

  34. TK is the supercell potential the current warned area in NH?? I have family and friends in that area. Thank you

  35. One of the severe thunderstorm warning I was just reading about in NH golf ball size hail 70 mph wind gusts. Tornado possible tag with it along with a considerable threat

    1. Thank you. A dear friend and husband, my niece and nephew and their families are all there. Hoping the worst skirts south of then.

  37. Looking at the power outages for NH 467 people without power according to poweroutage.us

  39. I chased yesterday and intercepted the 2 main super cells and observed (from just outside) the 2 other storm clusters that followed.

    Notes…
    -Great cloud structure
    -Underneath the storms the downpours were intense
    -Lack of lightning, but still some observed (lack of prolific lightning again due to the storm towers being relatively small, i.e. not reaching too high into the atmosphere)
    -Minimal damage – just some small hail and moderate wind gusts
    -Rotation in storms was too weak to warrant tornado warnings
