7:40AM

DAYS 1-5 (SEPTEMBER 14-18)
Changes over the next 5 days but timing of things allows a great weekend ahead. First today it takes some time to get rid of low level moisture with areas of fog and lots of cloudiness gradually dissipating for more sun, then high pressure dominating for a great weather weekend. By later Monday and especially Tuesday the weather will go downhill as a disturbance from the west and the remnants of Florence approach and move in, with a return to some wet weather. Forecast details…
TODAY: Areas of fog early. Mostly cloudy start, mostly sunny finish. Highs 72-80. Wind light N.
TONIGHT: Areas of low clouds and patchy fog redevelop. Lows 58-64. Wind light variable.
SATURDAY: Partly to mostly sunny. Highs 74-82. Wind light variable.
SATURDAY NIGHT: Areas of low clouds and patchy fog redevelop. Lows 58-64. Wind light variable.
SUNDAY: Partly to mostly sunny. Highs 74-82. Wind light variable.
MONDAY: Sunny start, cloudy finish, possible rain at night. Lows in the 50s. Highs in the 70s.
TUESDAY: Cloudy. Rain or showers likely. Chance of thunderstorms. Humid. Lows in the 60s. Highs in the 70s.

DAYS 6-10 (SEPTEMBER 19-23)
Fair weather returns September 19-20 before a front moves through around September 21 with a shower threat, then more fair weather after that. Temperatures near to above normal overall.

DAYS 11-15 (SEPTEMBER 24-28)
Mild with fair weather to start, a shower threat, then a shot of cooler air to finish the period in a fairly progressive pattern.

7:34AM

DAYS 1-5 (SEPTEMBER 13-17)
One more unsettled day today as an old boundary slowly dissipates over the region but lots of moisture remains in place with little to push it away. High pressure builds over the region starting Friday lasting through the remainder of this period with great weather. Discussion about Florence will be in the comments section between myself and anybody else that wants to participate. Forecast details…
TODAY: Mostly cloudy. Showers and thunderstorms near the South Coast until mid morning. Highs 70-78. Wind light NE to N.
TONIGHT: Mostly cloudy. Areas of fog. Lows 60-67. Wind light variable.
FRIDAY: Mostly cloudy start, mostly sunny finish. Highs 72-80. Wind light N.
SATURDAY THROUGH MONDAY: Mostly sunny. Lows from the upper 50s to lower 60s. Highs from the middle 70s to lower 80s.

DAYS 6-10 (SEPTEMBER 18-22)
A risk of some wet weather front a front moving through from the west and possibly some moisture associated with the remains of Florence in the September 18-19 window, dry and cooler September 20-21 then a quick warm-up at the end of the period.

DAYS 11-15 (SEPTEMBER 23-27)
A more progressive pattern, starting warm followed by a shower threat then a shot of cooler/drier air.

7:16AM

DAYS 1-5 (SEPTEMBER 12-16)
An old frontal boundary will sit over the region today and Thursday, providing some focus for shower and thunderstorm development. High pressure strengthens over the region at the end of the week and erodes the boundary and replaces unsettled weather with fair weather. Meanwhile, the Hurricane Florence watch continues as the powerful hurricane nears the Carolinas where it looks like there will be a landfall, the details of which (speed and direction of storm) are still somewhat unknown. There will be serious storm surge, rainfall, and wind in that area, with major impact. One possible positive aspect may be that the storm may, after intensifying some today, start to weaken and briefly make a turn to parallel the coast before eventually landfalling. This could expand the area impacted by surge but at the same time lessen the level of it. It also would mean slightly lesser wind impact if the weakening were significant enough. Rainfall is always a wildcard and we’ll have to see where heavier bands set-up and move. If we ever hear from the remnants, it will not be before the end of this 5-day period. Forecast details…
TODAY: Mostly cloudy. Scattered showers and thunderstorms, favoring RI and eastern MA this morning, and favoring areas closer to the South Coast this afternoon. Highs 70-78. Wind NE 5-15 MPH.
TONIGHT: Mostly cloudy. Areas of fog. Scattered showers. Lows 60-67. Wind light NE.
THURSDAY: Mostly cloudy. Isolated to scattered showers and thunderstorms, favoring the morning hours. Highs 70-78. Wind light NE to E.
THURSDAY NIGHT: Mostly cloudy. Areas of fog. Lows 60-67. Wind light variable.
FRIDAY: Partly sunny. Highs 72-80. Wind light variable.
SATURDAY & SUNDAY: Mostly sunny. Lows from the upper 50s to lower 60s. Highs from the middle 70s to lower 80s.

DAYS 6-10 (SEPTEMBER 17-21)
A risk of some wet weather front a front moving through from the west and possibly some moisture associated with Florence anywhere from later September 17 through September 19, then a shot of cooler/drier air to end the period.

DAYS 11-15 (SEPTEMBER 22-26)
A more progressive pattern, warming up early in the period, a risk of showers following that, and then a cool down to end the period.

7:27AM

DAYS 1-5 (SEPTEMBER 11-15)
Boundary sits over the region for a few days with unsettled weather, then dry air pushes in from the north late this week and brings improvement. All the while we’ll be watching Hurricane Florence for its impact to the south, looking more and more like at least some kind of landfall on the NC Coast, speed and exact position to be determined. Either way major impacts will take place down there and you’ll find discussions about that in the comments section. Forecast details…
TODAY THROUGH THURSDAY: Mostly cloudy. Isolated to scattered showers and thunderstorms. Patchy fog. Humid. Highs 70-80. Lows 60-70. Wind variable 5-15 MPH.
FRIDAY & SATURDAY: Mostly sunny. Lows from the upper 50s to lower 60s. Highs from the lower 70s to lower 80s.

DAYS 6-10 (SEPTEMBER 16-20)
Fair weather to start as high pressure dominates, then some occasional unsettled weather follows and some of this may be associated with remains of Florence, depending on where that goes. Temperatures near to above normal.

DAYS 11-15 (SEPTEMBER 21-25)
A little more changeable weather expected with cool shots early and late in the period, a warm-up mid period and a risk of some wet weather before the second cool shot.

7:33AM

DAYS 1-5 (SEPTEMBER 10-14)
As far as our forecast is concerned there are no significant changes to make for today’s blog update. The remains of TS Gordon combined with Midwest low pressure bring wet weather into the region during today and deliver humidity back to the region tonight and Tuesday, along with a shower/t-storm risk, that will last into midweek. It should dry out a bit later in the week as a little drier air works down from the Maritimes with another in a seemingly endless string of high pressure areas building across southeastern Canada. Meanwhile, the Florence watch will continue with the only impact here being increased ocean swells later in the week. The storm itself will impact the Carolinas more directly starting at midweek and it is still unclear if it will plow straight inland or slow down and start meandering. Hope to have a clearer picture of this by tomorrow. Forecast details…
TODAY: Cloudy. Rain arriving west to east, steadiest north and west of Boston. Highs 61-67. Wind E to SE 5-15 MPH but higher gusts.
TONIGHT: Cloudy. Rain tapering to showers. Areas of fog. Humid. Lows 58-65 early then slowly rising. Wind SE to SW 5-15 MPH, diminishing.
TUESDAY: Partly sunny. Humid. Scattered to isolated showers and thunderstorms. Highs 76-84. Wind SW 5-15 MPH becoming variable.
TUESDAY NIGHT: Partly cloudy. Humid. Isolated showers and thunderstorms. Lows 67-74. Wind light variable.
WEDNESDAY: Partly sunny. Isolated showers favoring the South Coast. Humid. Highs 77-84. Wind light variable.
THURSDAY: Partly cloudy. Isolated showers near the South Coast. Humid. Lows in the 60s. Highs from the upper 70s to middle 80s.
FRIDAY: Partly cloudy. Less humid. Lows from the upper 50s to lower 60s. Highs from the middle 70s to lower 80s.

DAYS 6-10 (SEPTEMBER 15-19)
High pressure will control our weather which will be fair and warmer than average September 15-16. During this time, we’ll be watching what Florence has done. Depending on the outcome, we may or may not see indirect impact here, but if there is going to be remnant rain, the September 17-18 period seems most likely with fair weather returning for the end of the period. Many details to work out.

DAYS 11-15 (SEPTEMBER 20-24)
Still lower than average confidence on this time period, but leaning toward a dry and warm start then a cooler trend, with mainly dry weather.

8:11AM

DAYS 1-5 (SEPTEMBER 9-13)
Our cooler weekend continues and again a day of very limited sun as that expansive high cloud veil connected to former TS Gordon fans across the region, then thickens up and lowers as the rainfall from the system gets here Monday, making for a wet start to the new week. This leads more humidity into the region which we will feel Tuesday through Thursday. It won’t be as oppressively humid or nearly as hot as recent days, however. The shower and thunderstorm threat will be greatest Tuesday with a boundary nearby and this will settle across the South Coast at midweek keeping a slight risk of a few showers there but otherwise the weather will be mainly rain-free by midweek. We’ll continue to monitor Hurricane Florence, which will be approaching the US Southeast Coast by midweek as well. There is no threat of an impact up here during this period, except for some increased ocean swells early to mid next week. Forecast details…
TODAY: Mostly cloudy – some filtered sunshine. Highs 64-71. Wind NE up to 10 MPH.
TONIGHT: Mostly cloudy. Lows 50-57. Wind light NE to E.
MONDAY: Cloudy. Rain arriving west to east morning. Rainy afternoon. More humid. Highs 62-69. Wind E to SE 5-15 MPH but higher gusts.
MONDAY NIGHT: Cloudy. Rain tapering to showers. Areas of fog. Humid. Lows 58-65. Wind SE to SW 5-15 MPH, diminishing.
TUESDAY: Partly sunny. Humid. Chance of showers. Slight chance of thunderstorms. Highs 76-84. Wind SW 5-15 MPH becoming variable.
WEDNESDAY & THURSDAY: Partly cloudy. Isolated showers near the South Coast. Humid. Lows in the 60s. Highs from the upper 70s to middle 80s.

DAYS 6-10 (SEPTEMBER 14-18)
High pressure will control our weather which will be fair and warmer than average September 14-16. During this time, we’ll be watching Hurricane Florence to the south. There is a range of possibilities with that hurricane that include a landfall somewhere on the US Southeast Coast to a sharp curve north then northeast near or just off the coast of North Carolina. Similar to what you read here yesterday, details won’t be known for a couple or a few days, possibly even right up until the time the storm arrives down there. If there were to be impacts from remnant rain it would most likely take place late in this forecast period.

DAYS 11-15 (SEPTEMBER 19-23)
Still lower than average confidence on this time period, but leaning toward a dry and warm start then a cooler trend to follow.

8:52AM

COMMENTARY
Today I will spare you a rant you’ve seen from me about media and I will let them either look like geniuses or fools on their own. No, I am not above any of these people. I don’t want that impression to be what comes out. I realize media today all plays the same game. Some of the people that appear on TV kind of hide this by masking it with their down-to-earth style, but they still have to give management what they want. Ratings. You’ve heard it all from me. I’ll just say this: I wish somebody would take a step back and reassess how this is being done, and what messages are actually getting to the audience. That will take some bravery in today’s media world.

DAYS 1-5 (SEPTEMBER 8-12)
A cool weekend is here, but not a bright one. Some may be disappointed that it won’t be that bright sunny type of fall feel, but we will have a lot of high cloudiness streaming over the region in the jet stream winds. This moisture in upper levels is actually connected to what was once Tropical Storm Gordon in the Gulf of Mexico, but the remnant rains from this system are going to hold off until Monday, so your weekend is a dry one, just not very sunny. Gone is the heat and humidity and that will stay away for a few days, although as the rain arrives Monday, you’ll start to feel that humidity returning, and it will be back by Tuesday and Wednesday, though not to the oppressive levels of previously, and this time without the extreme heat, just warm September weather. Enjoy the cool, dry interlude in the mean time if that is what you dig. Onto the forecast details…
TODAY: Mostly cloudy – some dim sunshine. Highs 67-74. Wind NE up to 10 MPH.
TONIGHT: Mostly cloudy. Lows 48-56. Wind NE up to 10 MPH.
SUNDAY: Mostly cloudy – some filtered sunshine. Highs 64-71. Wind NE up to 10 MPH.
SUNDAY NIGHT: Mostly cloudy. Lows 50-57. Wind light NE to E.
MONDAY: Cloudy. Rain arriving west to east morning. Rainy afternoon. More humid. Highs 62-69. Wind E to SE 5-15 MPH.
TUESDAY: Partly sunny. Humid. Chance of showers. Slight chance of thunderstorms. Lows from the upper 50s to lower 60s. Highs from the upper 70s to middle 80s.
WEDNESDAY: Partly cloudy. Humid. Lows in the 60s. Highs in the 80s.

DAYS 6-10 (SEPTEMBER 13-17)
High pressure will control our weather which will be fair and warmer than average September 13-15. During this time, we’ll be watching Hurricane Florence to the south. There is a range of possibilities with that hurricane that include a landfall somewhere on the US Southeast Coast to a sharp curve north then northeast near or just off the coast of North Carolina. We won’t know for a few days yet which is most likely, or if its something else entirely. But if a Southeast Coast landfall occurs there could be remnant rain from the system arriving in this area either September 16 or 17, depending on movement of the weakening system once over land. If a sharp recurve occurred there may never be any impact, weatherwise. In either case, we will see increased surf and ocean swells along the coast, especially south-facing shores, during next week.

DAYS 11-15 (SEPTEMBER 18-22)
With the inability to have a high confidence forecast at the end of the 6-10 day period that pretty much puts the 11-15 into a lower confidence mode, but it does look like a mainly dry time with above normal temperatures to start and possibly a quick cool-down later. There may be other tropical activity to watch as well.

7:23AM

DAYS 1-5 (SEPTEMBER 7-11)
The cold front through dropped through the region late yesterday, triggered showers and thunderstorms, is not that far south of the region today and will hang up for a time as a disturbance moves along it. This will hold clouds and a few showers in the region today before high pressure in eastern Canada provides a stronger push and brings a nice fall preview weekend. Low pressure that was once TS Gordon in the Gulf of Mexico will approach New England via the Midwest / Great Lakes bringing wet weather Monday as it pushes humid air back toward the region, which gets in here and sets up an additional risk of showers Tuesday as a cold front sweeps across the region. Forecast details…
TODAY: Mostly cloudy. Risk of a few showers south of the Mass Pike mainly in the morning. Less humid. Highs 72-80. Wind N up to 10 MPH.
TONIGHT: Partly cloudy. Lows 55-63. Wind light N.
SATURDAY: Partly sunny. Highs 68-75. Wind light NE.
SATURDAY NIGHT: Partly cloudy. Lows 46-53 most interior areas, 54-60 coastal and urban areas. Wind light NE.
SUNDAY: Mostly sunny. Highs 65-72. Wind light NE.
MONDAY: Cloudy. Rain likely. Lows in the 50s. Highs from the middle 60s to lower 70s.
TUESDAY: Partly sunny. Chance of showers and a slight risk of thunderstorms. Humid. Lows in the 60s. Highs from the middle 70s to lower 80s.

DAYS 6-10 (SEPTEMBER 12-16)
Subtropical high pressure dominates the weather pattern for a good portion of this period with warm and humid weather and a risk of a few showers/storms. We’ll also have to keep an eye on Hurricane Florence forecast to be somewhere off the East Coast around mid period. To me, odds still favor a recurve out to sea but I cannot rule out an East Coast impact at this point. The system will definitely create rough surf and large swells as even systems well offshore often do.

DAYS 11-15 (SEPTEMBER 17-21)
A couple shots of cooler air are possible this period but the overall weather forecast is low confidence due to the uncertainty preceding it. Does look like a mostly dry time.

7:36AM

DAYS 1-5 (SEPTEMBER 6-10)
Heat and humidity is back today as expected, but a stronger cold front is on the way. First this front brings the risk of showers and thunderstorms this afternoon and evening from northwest to southeast, and then introduces cooler and drier air for Friday and the weekend. The front won’t be that far to the south, however, so some cloudiness may hang around at times, especially Friday when some showers may linger mainly south of the Mass Pike during the morning. By Monday, low pressure approaches from the Great Lakes and will also contain moisture from former TS Gordon, bringing unsettled weather. Forecast details…
TODAY: Partly sunny. Scattered afternoon and evening showers/thunderstorms. Humid. Highs 80-86 South Coast, 87-93 elsewhere. Wind SW 10-20 MPH.
TONIGHT: Mostly cloudy. Showers and thunderstorms possible early mainly south of Boston and Worcester. Partly cloudy with patchy fog overnight. Humid. Lows 60-67. Wind shifting to NW 5-15 MPH.
FRIDAY: Variably cloudy. Risk of a few showers south of the Mass Pike mainly in the morning. Less humid. Highs 72-80. Wind N up to 10 MPH.
FRIDAY NIGHT: Partly cloudy. Lows 55-63. Wind light N.
SATURDAY: Partly sunny. Highs 68-75. Wind light NE.
SUNDAY: Mostly sunny. Pleasant. Lows from the upper 40s to middle 50s interior, upper 50s coastal and urban areas. Highs from the upper 60s to lower 70s.
MONDAY: Mostly cloudy. Chance of rain or showers. Lows in the 50s. Highs from the upper 60s to middle 70s.

DAYS 6-10 (SEPTEMBER 11-15)
Most of this period should feature dry weather and a return to above normal temperatures as high pressure dominates. However we will have to keep an eye on Hurricane Florence mid to late period. Early odds favor the system staying offshore, but either way there will be coastal impact due to at least building surf.

DAYS 11-15 (SEPTEMBER 16-20)
High pressure ridging will control the weather again with mainly dry weather and above normal temperatures expected.

7:37AM

DAYS 1-5 (SEPTEMBER 5-9)
Heat came down a peg or 2 yesterday and hangs back slightly today, though still very warm and moderately humid, then heat and higher humidity are back for Thursday along with the chance for showers and thunderstorms as a cold front approaches. This front, unlike the previous, will bring genuine cooling in for Friday and the weekend, which now looks mainly dry as moisture associated with Gordon and a system to the west will likely hold off until early next week. Forecast details…
TODAY: Mostly sunny. Moderately humid. Highs 78-86. Wind E up to 10 MPH shifting to S.
TONIGHT: Partly cloudy. More humid. Lows 66-72. Wind S to SW up to 10 MPH.
THURSDAY: Partly sunny. Scattered afternoon and evening showers/thunderstorms. Humid. Highs 80-86 South Coast, 87-93 elsewhere. Wind SW 10-20 MPH.
THURSDAY NIGHT: Mostly cloudy with a chance of showers early. Partly cloudy with patchy fog overnight. Humid. Lows 60-67. Wind shifting to NW 5-15 MPH.
FRIDAY: Variably cloudy. Risk of a few showers South Coast. Less humid. Highs 72-80. Wind N up to 10 MPH.
SATURDAY: Partly cloudy. Comfortable. Lows from the upper 50s to lower 60s. Highs from the upper 60s to middle 70s.
SUNDAY: Mostly sunny. Pleasant. Lows from the upper 40s to middle 50s interior, upper 50s coastal and urban areas. Highs from the upper 60s to lower 70s.

DAYS 6-10 (SEPTEMBER 10-14)
Unsettled weather with rain or showers September 10 as a system from the west and moisture from Gordon move through. Clearing September 11 and fair through the remainder of the period with a warming trend.

DAYS 11-15 (SEPTEMBER 15-19)
High pressure ridging will overtake the weather again with mainly dry weather and above normal temperatures expected.

7:33AM

DAYS 1-5 (SEPTEMBER 4-8)
The heat and humidity in this latest bout peaked on Monday as you will notice today being a little less hot and also may notice a downward trend in the humidity, but it will be subtle as a fairly inactive back door cold front slips across the region from northeast to southwest. These fronts carry much less impact at this time of year than they do in the spring, but it will be enough to take the edge off the heat/humidity into Wednesday. Any shower activity with this front will be isolated and mainly well west and southwest of Boston this afternoon, otherwise expect no threat of rain through Wednesday, even as the boundary starts a northeastward return. By Wednesday night into Thursday we’re back in the heat and humidity for a short time. A stronger cold front will move through late in the day and evening from northwest to southeast, bringing a greater threat of showers and thunderstorms, then introducing a cooler/drier air mass to the region during Friday and into the weekend. Friday may be somewhat slow to clear as the front will be slowing down as it exits the South Coast, so that day may end up more cloud-dominated than Saturday will likely turn out. Forecast details…
TODAY: Partly cloudy. Slight chance of an isolated shower or thunderstorm mainly mid to late afternoon west and southwest of Boston. Slightly less humid. Highs 77-82 Cape Cod, 83-88 eastern MA and NH Seacoast, 88-93 elsewhere. Wind light variable becoming light NE.
TONIGHT: Partly cloudy. Less humid. Lows 60-67. Wind light NE to E.
WEDNESDAY: Mostly sunny. Moderately humid. Highs 78-86. Wind E up to 10 MPH shifting to S.
WEDNESDAY NIGHT: Partly cloudy. More humid. Lows 66-72. Wind S to SW up to 10 MPH.
THURSDAY: Partly sunny. Scattered afternoon and evening showers/thunderstorms. Humid. Highs 80-86 South Coast, 87-93 elsewhere. Wind SW 10-20 MPH.
FRIDAY: Mostly cloudy. Chance of showers, favoring the South Coast in the morning. Less humid. Lows in the 60s. Highs in the 70s.
SATURDAY: Partly cloudy. Comfortable. Lows from the upper 50s to lower 60s. Highs from the upper 60s to middle 70s.

DAYS 6-10 (SEPTEMBER 9-13)
A rather cool day Sunday September 9 and clouds are expected to increase. It may turn wet before day’s end from the combination of a low pressure area passing through the Great Lakes and moisture that was associated with Gulf of Mexico tropical system Gordon. As that area passes to the north a trailing front will bring additional unsettled weather September 10 before a brief drier/cooler shot September 11 and a quick warm-up following it later next week with mainly dry weather. Odds favor TS or Hurricane Florence making a turn near or east of Bermuda around the middle to end of next week and not impacting the East Coast but will continue to monitor that storm.

DAYS 11-15 (SEPTEMBER 14-18)
High pressure ridging will overtake the weather again with mainly dry weather and above normal temperatures expected. However with this pattern in place and tropical systems potentially off the coast, always something to keep a close eye on.

7:32AM

DAYS 1-5 (SEPTEMBER 3-7)
One more day to the long weekend and it will be hottest one as a south to southwest flow pumps in that summertime air. The heat continues into Tuesday but will be cut off from northeast to southwest as a back-door front slips through during the course of the day and evening. Don’t look for a huge temperature drop as ocean temperatures are at their warmest now, but you will notice a change gradually beginning later in the day or evening depending on where you are. This will set up a “less hot” but still warm Wednesday as the air flow starts from the east then turns more southerly as high pressure slides to the southeast. The boundary that comes through later Tuesday returns to the north and reintroduces some heat and humidity for Thursday, before a cold front from the northwest puts an end to that surge by Friday. This front may bring some showers and storms to the region later Thursday and some of these showers may linger into Friday as the front starts to slow down while exiting the South Coast. Forecast details…
TODAY – LABOR DAY: Mostly sunny. Humid. Highs 78-85 South Coast, 86-93 elsewhere. Wind S to SW 5-15 MPH.
TONIGHT: Partly cloudy. Patchy fog. Humid. Lows 66-72. Wind SW up to 10 MPH.
TUESDAY: Partly cloudy. Slight chance of an isolated shower or thunderstorm. Humid. Highs 80-86 South Coast, 87-93 elsewhere. Wind W up to 10 MPH in the morning shifting to NE from northeast to southwest during the afternoon.
TUESDAY NIGHT: Partly cloudy. Less humid. Lows 60-67. Wind light NE to E.
WEDNESDAY: Mostly sunny. Highs 78-86. Wind E up to 10 MPH shifting to S.
THURSDAY: Partly sunny. Isolated to scattered showers and thunderstorms mainly late day and evening. More humid. Lows in the 60s. Highs from the lower to middle 80s South Coast, upper 80s to lower 90s elsewhere.
FRIDAY: Mostly cloudy. Chance of showers, favoring the South Coast in the morning. Less humid. Lows in the 60s. Highs in the 70s.

DAYS 6-10 (SEPTEMBER 8-12)
Going for a weekend split right now with dry weather September 8 as high pressure from the north pushes far enough south for dry and cooler weather, then low pressure in the Great Lakes approaches September 9, having entrained some moisture from a tropical system from the Gulf of Mexico, to bring some wet weather by later in the weekend. Still have timing details to work out. It may continue unsettled into September 10 before we get a brief shot of cooler/drier air followed by a quick warm-up late in the period.

DAYS 11-15 (SEPTEMBER 13-17)
Current indications are for a warm and mainly dry weather pattern but we’ll have to potentially keep an eye on an offshore tropical system. Odds favor it not being an impact at this time.

10:58AM

DAYS 1-5 (SEPTEMBER 2-6)
As the holiday weekend rolls on (and goes by far too quickly for many) we’ll see a building of heat and humidity as high pressure sinks to the south and ends up east of New England by Monday. It sits there Tuesday as well which will be another hot and humid day, but we will have to also introduce the chance of showers and thunderstorms in the forecast as a cold front approaches from the north. This does not look like a front that is going to be a prolific rain-producer, and only expecting these showers and storms to be isolated. This front slips to the south Wednesday, taking the edge off the heat and humidity as the air flow comes in from the Atlantic with high pressure in a recently familiar place in eastern Canada. But the boundary goes right back to the north for Thursday, allowing heat and humidity back. This is all part of that ridge-dominated pattern in which the overall temperatures are warm, but the degree of that warmth is dependent on what is going on at the surface. Forecast details…
TODAY: Clouds and sun. More humid. Highs 72-78 South Coast, 78-84 elsewhere. Wind S 5-15 MPH.
TONIGHT: Partly cloudy. Patchy fog. Humid. Lows 64-70. Wind S to SW up to 10 MPH.
MONDAY – LABOR DAY: Partly cloudy. Humid. Highs 78-85 South Coast, 86-93 elsewhere. Wind S to SW 5-15 MPH.
MONDAY NIGHT: Partly cloudy. Patchy fog. Humid. Lows 66-72. Wind SW up to 10 MPH.
TUESDAY: Partly cloudy. Isolated showers and thunderstorms in the afternoon and evening. Highs 80-86 South Coast, 87-93 elsewhere. Wind SW 5-15 MPH.
WEDNESDAY: Partly cloudy. Less humid. Lows in the 60s. Highs in the 80s.
THURSDAY: Partly sunny. Slight risk of isolated showers and thunderstorms. More humid. Lows in the 60s. Highs from the lower to middle 80s South Coast, upper 80s to lower 90s elsewhere.

DAYS 6-10 (SEPTEMBER 7-11)
The boundary that will be wavering around in the days before this will settle to the south of the region during Friday September 7 which ends up an unsettled day with a risk of showers. There is uncertainty for the September 8-9 weekend because of the position of that boundary and the strength of a push of cooler/drier air courtesy high pressure in eastern Canada. With luck, that push will be strong enough so that the weekend is fair and comfortable, but this is no guarantee. The boundary may try to come back north briefly about September 10 before being pushed southward again at the end of the period, so the cooler/drier air will make a valiant effort to gain more control during this particular period, although there will be details to iron out.

DAYS 11-15 (SEPTEMBER 12-16)
I am still of the opinion that subtropical high pressure dominates with the warmer side of things being more dominant once again. The weather in the region would likely be mainly dry but not without a few shower and thunderstorm opportunities. As previously mentioned, we’ll also be paying attention to things in the tropics as they have become a little more active.

10:30AM

DAYS 1-5 (SEPTEMBER 1-5)
Labor Day Weekend! The “unofficial” final weekend of summer, but we end summer in so many different ways and places I suppose this is really just Labor Day Weekend and you can label it anything you like. But one thing we can say is that the weather will be quite decent for outdoor activity, although as we get into tomorrow and Monday the heat and humidity will be on the increase after a rather comfortable start to the weekend today. This is accomplished as high pressure, which has been centered to the north of New England, sinks to the southeast and turns winds from easterly to southerly during the course of the next 3 days. A surface boundary that brought the cooler air in after recent heat will be returning as a warm front during Sunday, which will be a cloudier day to start with but will also turn out at least partly sunny. By Monday will be fully in a south to southwest flow of hot/humid air, though heat will not be as intense as the recent spell we had. Upper level high pressure again will be in full control of the weather as we get beyond the holiday weekend into the middle of next week. A surface boundary coming through later Tuesday may trigger a few showers and thunderstorms in the area and a wind shift to the northeast will take the edge off the heat by Wednesday. Forecast details…
TODAY: Sun/cloud mix. Highs 68-76, coolest coast. Wind E 5-15 MPH.
TONIGHT: Mostly cloudy. Lows 60-67. Wind light SE.

DAYS 6-10 (SEPTEMBER 6-10)
Winds turn southerly again as surface high pressure slips off to the southeast September 6 (familiar pattern recently) and the heat comes back along with some humidity. Another boundary moves through on September 7 which will trend cooler with clouds and occasional showers. High pressure to the north during the September 8-9 weekend should keep it cooler but it’s unclear yet on whether the boundary that had come through will be far enough south to allow fair weather or it slides back to the north somewhat and brings unsettled weather. Too far away for certainty but leaning toward a split decision dry start wet finish for that weekend and it may remain unsettled into September 10. Low confidence on this particular forecast period.

DAYS 11-15 (SEPTEMBER 11-15)
As we get into the middle of September, though the daily details are impossible to nail down beyond 10 days away, the large scale pattern is one we’ll have to pay close attention to. It does look like the subtropical high pressure ridge that’s been largely in control of the pattern lately will continue to be in control. What happens here will be determined by surface features, warm to hot/humid when a surface boundary is to our north, and cooler when it slips to the south and high pressure moves across eastern Canada. The other thing we will need to pay attention to is the tropics, which are becoming more active as we head toward and through the climate peak of the season. The weather pattern has not favored many systems this season so far, but this has shifted to allow more activity. I don’t foresee a threat to New England during this period at this time, however past history says the weather pattern upcoming is one you don’t let your guard down either.

DAYS 1-5 (AUGUST 31-SEPTEMBER 4)
A cooler interlude is underway as high pressure passes north of the region today and Saturday bringing Maritime air across the region, and then warm to hot weather will return as the high sinks to the south and turns surface winds more southerly during the course of and shortly after the Labor Day Weekend. The next boundary’s timing appears to be later Tuesday so will shift the next shower and thunderstorm threat to then. Forecast details…
TODAY: Partly sunny. Highs 72-78. Wind NE 5-15 MPH.
TONIGHT: Partly cloudy. Lows 59-64. Wind light NE.
SATURDAY: Partly sunny. Highs 68-75, coolest coast. Wind light NE to E.
SATURDAY NIGHT: Partly cloudy. Lows 60-67. Wind light SE to S.
SUNDAY: Partly sunny. More humid. Highs 77-85, coolest South Coast. Wind S 5-15 MPH.
MONDAY – LABOR DAY: Partly cloudy. Humid. Lows in the 60s. Highs from the lower 80s to lower 90s, cooler South Coast.
TUESDAY: Partly cloudy. Chance of a shower or thunderstorm late. Humid. Lows from the middle 60s to around 70. Highs from the middle 80s to lower 90s, cooler South Coast.

DAYS 6-10 (SEPTEMBER 5-9)
Warm to hot weather early in the period with a risk of a shower or thunderstorm, then the similar pattern we’ve been repeats with a cool-down from high pressure moving across eastern Canada.

DAYS 11-15 (SEPTEMBER 10-14)
May see yet another cycle of the same pattern, warm up, risk of showers/storms, then cool down.
