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.
SUNDAY: Mostly cloudy to partly sunny. More humid. Highs 72-78 South Coast, 78-84 elsewhere. Wind S 5-15 MPH.
SUNDAY NIGHT: 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.
TUESDAY: Partly cloudy. Chance of a late day or nighttime shower or thunderstorm. Humid. Lows from the upper 60s to lower 70s. Highs from the lower to middle 80s South Coast, upper 80s to middle 90s elsewhere.
WEDNESDAY: Partly cloudy. Less humid. Lows in the 60s. Highs in the 80s.

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.

7:30AM

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.

7:30AM

DAYS 1-5 (AUGUST 30-SEPTEMBER 3)
Transition day today as a cold front crosses the region. It will still be rather warm and humid especially through early afternoon and the front may trigger a few showers and thunderstorms as it crosses, first to the northwest, then later toward southeastern MA and RI, and by evening you’ll notice a cooling/drying process underway. It will never get bone-dry as the air will be coming from the northeast due to the orientation of high pressure to the north. But in comparison to recent weather, it will be very refreshing and in full effect through Friday. The Labor Day Weekend will feature a slow transition as this high slips to the southeast, starting on the cooler side Saturday and turning out quite warm and more humid by its conclusion. Forecast details…
TODAY: Variably cloudy. Scattered showers/thunderstorms. Humid. Highs 84-92, cooler Cape Cod. Wind NW shifting to NE 5-15 MPH.
TONIGHT: Mostly cloudy. Less humid. Lows 60-67. Wind NE 5-15 MPH.
FRIDAY: Partly sunny. Highs 72-78. Wind NE 5-15 MPH.
FRIDAY NIGHT: Mostly cloudy. Lows 59-64. Wind light NE.
SATURDAY: Mostly cloudy. Highs 68-75, coolest coast. Wind light NE to E.
SUNDAY: Partly sunny. More humid. Lows from the lower to middle 60s. Highs from the middle 70s to lower 80s.
MONDAY – LABOR DAY: Partly cloudy. Humid. Lows in the 60s. Highs in the 80s.

DAYS 6-10 (SEPTEMBER 4-8)
High pressure dominates surface and aloft with mainly dry and warm to hot weather September 4-5 followed by a transition similar to this week to cooler weather during the September 6-8 period.

DAYS 11-15 (SEPTEMBER 9-13)
High pressure dominates and the pattern of above normal temperatures and below normal rainfall is expected to continue.

7:30AM

DAYS 1-5 (AUGUST 29-SEPTEMBER 2)
The heat dome retains control for one more day before a cold front puts an end to it Thursday, the transition day. Still think any strong storms will be more the exception than the rule on Thursday, but something to monitor as the front move through from northwest to southeast. A much cooler northeasterly to easterly air flow will be in control Friday and Saturday, but by Sunday we’ll already be getting into a warmer southerly air flow as the high pressure area sinks to the southeast.
Forecast details…
TODAY: Hazy sun. Humid. Highs 82-90 Nantucket, 88-95 Martha’s Vineyard and Cape Cod, 95-102 elsewhere, hottest interior valleys. Wind SW 5-15 MPH.
TONIGHT: Partly cloudy. Hazy. Muggy. Lows 73-82. Wind light SW.
THURSDAY: Variably cloudy. Scattered showers/thunderstorms. Humid. Lows from the upper 60s to middle 70s. Highs in the 80s to near 90.
THURSDAY NIGHT: Mostly cloudy. Less humid. Lows 60-67. Wind NW 5-15 MPH.
FRIDAY: Partly sunny. Highs 72-78. Wind NE 5-15 MPH.
SATURDAY: Mostly cloudy. Lows from the upper 50s to lower 60s. Highs from upper 60s to lower 70s.
SUNDAY: Partly sunny. More humid. Lows from the lower to middle 60s. Highs from the middle 70s to lower 80s.

DAYS 6-10 (SEPTEMBER 3-7)
Labor Day Monday September 3 will be warm and humid with a shower or thunderstorm possible late in the day. High pressure dominates surface and aloft with mainly dry and warm to hot weather September 4-5 until a front gets closer and may bring a few showers and a bit of a cool down later in the period.

DAYS 11-15 (SEPTEMBER 8-12)
High pressure dominates and the pattern of above normal temperatures and below normal rainfall is expected to continue.

7:08AM

COMMENTARY
I understand. There are some people who struggle badly in heat and humidity. I am completely sympathetic to that. What irks me is the media’s handling of hot weather. We are constantly bombarded with headlines and breaking news making it sound like this is the worst stretch of heat ever. It’s not. Sorry media. The majority of folks can handle heat a lot more than you give them credit for. Pay attention. This is loosely tied into another media issue I saw yesterday. A tropical storm forms in the eastern Pacific, oh, about 2000 miles east of Hawaii. By the way, this happens up to several times every tropical season. Of course those headlines have to mention that it’s heading for Hawaii. Well technically that is correct. It is. Only thing is, this is completely irrelevant because it will turn north and dissipate, missing the islands by….oh, about 1000 miles. WOW, WHAT A CLOSE CALL! The pathetic media needs to start just getting back to basics. I have a feeling this isn’t coming anytime soon.

DAYS 1-5 (AUGUST 28-SEPTEMBER 1)
We’ll be under the hot high pressure ridge for the next 2 days, the “heat dome”, and yes it will be very hot and also rather humid. Everybody should stay hydrated and out of direct sun, also avoiding strenuous outdoor activity whenever possible. A few record temperatures may occur. The heat will then break during Thursday and Friday as a cold front moves northwest to southeast across the region. The timing of this front and the warmth of the air aloft may inhibit thunderstorm development somewhat, and while I cannot rule out some strong storms at some point Thursday as this front moves through, it doesn’t look like we’ll be dealing with any widespread severe weather. By Friday, a much cooler northeasterly air flow will have taken over as high pressure moves across southeastern Canada and far northern New England. This northeast to east flow will continue into the start of the Labor Day Weekend on Saturday, which may feature a lot of cloudiness too. Forecast details…
TODAY: Hazy sun. Humid. Highs 80-88 Nantucket, 89-97 elsewhere. Wind SW 5-15 MPH.
TONIGHT: Hazy but clear. Humid. Lows 68-78, warmest urban areas. Wind light SW.
WEDNESDAY: Hazy sun. Humid. Highs 82-90 Nantucket, 91-100 elsewhere, hottest interior valleys. Wind SW 5-15 MPH.
WEDNESDAY NIGHT: Partly cloudy. Hazy. Muggy. Lows 70-79. Wind light SW.
THURSDAY: Variably cloudy. Scattered showers/thunderstorms. Humid. Lows from the upper 60s to middle 70s. Highs in the 80s to near 90.
FRIDAY: Partly sunny. Less humid. Lows in the 60s. Highs in the 70s.
SATURDAY: Mostly cloudy. Lows from the upper 50s to lower 60s. Highs from upper 60s to lower 70s.

DAYS 6-10 (SEPTEMBER 2-6)
High pressure will sink to the south and turn the wind more southerly during Sunday September 2 and Monday September 3 of Labor Day Weekend and a cold front will approach by late Monday. Sunday should be rain-free. Monday carries the chance of some late day showers/t-storms. High pressure dominates surface and aloft with mainly dry and warm to hot weather September 4-6.

DAYS 11-15 (SEPTEMBER 7-11)
High pressure dominates and the pattern of above normal temperatures and below normal rainfall is expected to continue.

6:45AM

DAYS 1-5 (AUGUST 27-31)
High pressure aloft will dominate the last several days of August, but some changes will be brought about by what goes on at the surface. It starts with 3 hot days through Wednesday with a westerly air flow, the hottest days being Tuesday and Wednesday, then a transition day Thursday as a cold front crosses the region, a little slower timing than was previously expected, so must add some showers and possible thunderstorms to the forecast as the front will have a little more chance to work with daytime heating. Still looking for a more northeasterly flow by Friday and cooler weather. Frontal boundary should be just far enough to the south for dry weather at that time. Forecast details…
TODAY: Hazy sun. More humid. Highs 84-93. Wind W 5-15 MPH.
TONIGHT: Partly cloudy. Humid. Lows 66-73. Wind SW 5-15 MPH.
TUESDAY: Hazy sun. Humid. Highs 90-97 except 80s parts of South Coast and Cape Cod. Wind SW 5-15 MPH, higher gusts.
TUESDAY NIGHT: Clear and hazy. Muggy. Lows 68-76. Wind light SW.
WEDNESDAY: Hazy sun. Humid. Highs 90-97 except 80s parts of South Coast and Cape Cod. Wind SW 5-15 MPH.
THURSDAY: Variably cloudy. Isolated to scattered showers southern NH and northern to central MA late morning through early afternoon. Scattered showers and possible thunderstorms southeastern MA, eastern CT, and RI, afternoon to early evening. Humid. Lows from the upper 60s to middle 70s. Highs in the 80s.
FRIDAY: Partly sunny. Less humid. Lows in the 60s. Highs in the 70s.

DAYS 6-10 (SEPTEMBER 1-5)
In a pattern we’ve seen a few times late this summer, Labor Day Weekend will feature surface high pressure sinking southward to the east of New England and a gradual shift of air flow from easterly to southerly as an old frontal boundary lifts back northward across the region. By Labor Day September 3 a weak front from the west will approach. There may be a few showers during the September 1-2 transition and a few showers/storms around September 3 as the front from the west moves in. September 4-5 look mild to warm with mainly dry weather.

DAYS 11-15 (SEPTEMBER 6-10)
A shot of building heat early through mid period as high pressure aloft strengthens over the region, then a shower/thunderstorm threat with a surface boundary in the region later in the period.

7:49AM

DAYS 1-5 (AUGUST 26-30)
High pressure will be in control of the weather throughout this period, which starts out comfortably warm and turns out hot and more humid, only to see an easing of heat and humidity by Thursday as a cold front comes through, possibly with no shower or thunderstorm activity at all. We’ll continue to see some smoke in the high altitudes from wildfires in the Canadian Rockies and western US at times. Forecast details…
TODAY: Sunshine again filtered at times by some high altitude smoke. Highs 78-86, coolest South Coast. Wind SW up to 10 MPH.
TONIGHT: Partly cloudy. More humid. Lows 63-70. Wind SW up to 10 MPH.
MONDAY: Mostly sunny and hazy. Humid. Highs 84-93. Wind W 5-15 MPH.
TUESDAY & WEDNESDAY: Hazy sunshine & a few clouds. Very humid. Lows from the upper 60s to middle 70s. Highs from the middle to upper 80s South Coast, 90s elsewhere.
THURSDAY: Slight shower risk early, otherwise partly cloudy. Less humid. Lows in the 60s. Highs in the 80s.

DAYS 6-10 (AUGUST 31-SEPTEMBER 4)
High pressure moves across eastern Canada and northern New England on the final day of August which will be a fair and somewhat cooler day with lower humidity. Labor Day Weekend September 1-3 currently looks like it will not be without the threat of a few showers but should be mostly rain-free with a gradual return to warmer and more humid weather. Hotter weather by September 4 as high pressure aloft is more in control again.

DAYS 11-15 (SEPTEMBER 5-9)
This period looks variable in temperature as a boundary may be nearby, possibly starting out very warm to hot and humid, then featuring somewhat of a cool down as high pressure to the south gives way to high pressure nosing out of Canada, with the boundary in between eventually being pushed southward. Hard to know this far in advance when threats of unsettled weather will be.

7:08AM

DAYS 1-5 (AUGUST 25-29)
High pressure will be in control of the weather throughout this period, which starts out comfortably warm and turns out hot and more humid. We’ll continue to see some smoke in the high altitudes from wildfires in the Canadian Rockies and western US at times through the weekend. Previously I had mentioned some old boundaries getting close to the region and although this is still true, I am currently thinking the air will be too warm aloft to support any shower and thunderstorm activity through this forecast period. Forecast details…
TODAY: Areas of fog early, otherwise sunshine filtered at times by high altitude smoke. Highs 77-85, coolest coast. Wind S up to 10 MPH.
TONIGHT: Mostly clear except some patchy ground fog forming late at night and also some areas of smoke continuing, filtering moonlight. Lows 61-68. Wind light SW.
SUNDAY: Sunshine again filtered at times by some high altitude smoke. Highs 78-86, coolest South Coast. Wind SW up to 10 MPH.
SUNDAY NIGHT: Partly cloudy. More humid. Lows 63-70. Wind SW up to 10 MPH.
MONDAY: Mostly sunny and hazy. Humid. Highs 84-93. Wind W 5-15 MPH.
TUESDAY & WEDNESDAY: Hazy sunshine & a few clouds. Very humid. Lows from the upper 60s to middle 70s. Highs from the middle to upper 80s South Coast, 90s elsewhere.

DAYS 6-10 (AUGUST 30-SEPTEMBER 3)
Expecting a cold front to come through dry early August 30 which will be not as hot, still quite warm, but becoming less humid, then high pressure moving to the north of the region will turn wind more onshore by August 31 which will be a fair and significantly cooler day. Labor Day Weekend September 1-3 currently looks like it will not be without the threat of a few showers but should be mostly rain-free with a gradual return to warmer and more humid weather.

DAYS 11-15 (SEPTEMBER 4-8)
This period looks variable in temperature as a boundary may be nearby, possibly starting out very warm to hot and humid, then featuring somewhat of a cool down as high pressure to the south gives way to high pressure nosing out of Canada, with the boundary in between eventually being pushed southward. Hard to know this far in advance when threats of unsettled weather will be.

7:31AM

DAYS 1-5 (AUGUST 24-28)
High pressure aloft will dominate the weather for the next several days. Weakening surface boundaries will try to get close to the region starting late in the weekend but they only bring remote risks for a few showers and thunderstorms as heat and humidity will be back in the picture by then. I hesitate to even put them in the forecast but will, just in case. Forecast details…
TODAY: Sunshine filtered by high altitude smoke at first then becoming brighter. Highs 76-84, coolest coast. Wind light variable with sea breezes.
TONIGHT: Clear. Lows 50-56 interior areas with coolest in the valleys to 56-62 elsewhere with mildest in urban areas. Wind light variable to SW.
SATURDAY: Mostly sunny. Highs 78-86, coolest South Coast. Wind SW 5-15 MPH.
SATURDAY NIGHT: Partly cloudy. Lows 58-64. Wind SW 5-15 MPH.
SUNDAY: Mostly sunny. Slightly more humid. Remote risk of a weakening shower far northwest of Boston by evening. Highs 75-80 immediate shores and Cape Cod, 81-88 elsewhere. Wind light SW to S with sea breezes.
MONDAY: Mostly sunny. Humid. Remote risk of isolated thunderstorm mainly far inland. Lows in the 60s. Highs from the lower 80s to lower 90s, coolest South Coast.
TUESDAY: Partly cloudy. Humid. Slight risk of isolated thunderstorms interior late day. Lows from the middle 60s to lower 70s. Highs from the upper 80s to middle 90s but cooler some coastal areas.

DAYS 6-10 (AUGUST 29-SEPTEMBER 2)
High pressure aloft will be in control with more heat during much of this period, including some higher humidity as well. A couple disturbances passing north of the region will be close enough to trigger shower and thunderstorm chances and if high pressure in eastern Canada is strong enough it may help get one of those boundaries through here with a bit of a cool-down later in the period.

DAYS 11-15 (SEPTEMBER 3-7)
General pattern remains the same but will have to watch for a quick cooler interlude of high pressure moving across Canada noses southward far enough. That may also mean we’ll be close to a surface boundary and may experience a higher risk of some shower and thunderstorm activity at times.

7:21AM

DAYS 1-5 (AUGUST 23-27)
A final trough moving through the area keeps clouds and perhaps results in a brief shower this morning but then you can expect more sunshine and comfortable air today. High pressure then takes control of the weather for several days which start out quite comfortable with a warming trend, then an eventual return to higher humidity. Forecast details…
TODAY: Lots of clouds and a possible brief shower until mid morning then increasing sunshine. Highs 75-82. Wind NW 5-15 MPH.
TONIGHT: Mostly clear. Lows 48-53 interior valleys, 54-60 elsewhere. Wind light NW to N.
FRIDAY: Sunny. Highs 76-84, coolest coast. Wind light variable with sea breezes.
FRIDAY NIGHT: Clear. Lows 50-56 interior areas with coolest in the valleys to 56-62 elsewhere with mildest in urban areas. Wind light variable to SW.
SATURDAY: Mostly sunny. Highs 78-86, coolest South Coast. Wind SW 5-15 MPH.
SUNDAY: Mostly sunny. Slightly more humid. Lows from the upper 50s to middle 60s. Highs in the 80s, some 70s Cape Cod and immediate shores.
MONDAY: Mostly sunny. Humid. Lows in the 60s. Highs from the lower 80s to lower 90s, coolest South Coast.

DAYS 6-10 (AUGUST 28-SEPTEMBER 1)
High pressure aloft will be in control with more heat during much of this period, including some higher humidity as well. A couple disturbances passing north of the region will be close enough to trigger shower and thunderstorm chances from time to time. At this time of year we also have to keep an eye on sea breeze boundaries for possible storm development focus regions too.

DAYS 11-15 (SEPTEMBER 2-6)
General pattern remains the same but will have to watch for a quick cooler interlude of high pressure moving across Canada noses southward far enough. That may also mean we’ll be close to a surface boundary and may experience a higher risk of some shower and thunderstorm activity at times.

7:55AM

DAYS 1-5 (AUGUST 22-26)
This is the one unsettled day of the week and it’s caused by a warm front / cold front combination moving across the region, first the warm front which is currently doing so from southwest to northeast with a fairly widespread area of rain and embedded downpours. Have to watch this area for a relatively short time until late morning in case a stronger thunderstorm as able to get going within it, as this would have the potential for damaging wind. It is a long shot chance. A wedge of very humid air will briefly visit between the 2 fronts, and the cold front will charge eastward across there region bringing a broken to scattered line of showers and thunderstorms. With this line there is a low probability of damaging wind gusts, but again any of that would be isolated. This line will cross Cape Cod later in the day. By evening, it’s gone and in comes a refreshing air mass from Canada. Removing the shower risk for Thursday’s forecast, just some fair weather clouds decorating the sky in an otherwise very nice late summer day. High pressure settles across the region Friday through Sunday which will feature great summer weather but a gradual warming trend and a slight increase in humidity daily. Forecast details…
TODAY: Mainly cloudy through late morning with numerous showers and possible embedded thunderstorms. Partly sunny midday and afternoon with a possible passing shower or thunderstorm west to east, earliest in central MA and eastern CT, then across southern NH, eastern MA, and RI, and lastly Cape Cod. Becoming very humid especially late morning through mid afternoon. Highs 76-84. Wind SE shifting to SW 5-15 MPH then shifting to W later in the day from west to east with higher gusts possible.
TONIGHT: Mostly clear. Drying out. Lows 58-65. Wind NW 5-15 MPH.
THURSDAY: Partly cloudy. Highs 75-82. Wind NW 5-15 MPH.
THURSDAY NIGHT: Mostly clear. Lows 48-53 interior valleys, 54-60 elsewhere. Wind light NW to N.
FRIDAY: Sunny. Highs 76-84, coolest coast. Wind light variable with sea breezes.
SATURDAY: Mostly sunny. Lows from around 50 interior valleys to around 60 urban areas. Highs from the upper 70s to middle 80s, coolest coast.
SUNDAY: Mostly sunny. Slightly more humid. Lows from the upper 50s to middle 60s. Highs in the 80s, some 70s Cape Cod and immediate shores.

DAYS 6-10 (AUGUST 27-31)
High pressure aloft will be in control with more heat during much of this period, including some higher humidity as well. A couple disturbances passing north of the region will be close enough to trigger shower and thunderstorm chances from time to time. At this time of year we also have to keep an eye on sea breeze boundaries for possible storm development focus regions too.

DAYS 11-15 (SEPTEMBER 1-5)
General pattern remains the same but will have to watch for a quick cooler interlude of high pressure moving across Canada noses southward far enough. That may also mean we’ll be close to a surface boundary and may experience a higher risk of some shower and thunderstorm activity at times.

DAYS 1-5 (AUGUST 21-25)
Easterly air flow for one more day, keeping clouds dominant today. Warm front passes through from southwest to northeast tonight and early Wednesday when the most numerous showers and possible storms will occur, then wet get into the muggy air for several hours Wednesday between it and an approaching cold front, which means scattered to isolated shower and thunderstorm activity though I suspect any given location will probably have several rain-free hours. We will have to watch any storms as they could be strong. A shot of cooler, drier air follows the cold front and we enjoy that Thursday before a warm-up follows. Still not ruling out an isolated shower or storm Thursday as an upper level disturbance crosses the region. Forecast details…
TODAY: Mostly cloudy. Highs 67-74, coolest coast. Wind E 5-15 MPH.
TONIGHT: Mostly cloudy. Patchy fog. Showers and a chance of thunderstorms overnight from southwest to northeast. Increasingly humid. Lows 62-67. Wind SE to S 5-15 MPH.
WEDNESDAY: Mostly cloudy with numerous to scattered showers and possible thunderstorms early morning, then partly sunny with scattered to isolated showers and thunderstorms remainder of day. Humid. Highs 77-85, coolest South Coast and Cape Cod. Wind SW 10-20 MPH.
WEDNESDAY NIGHT: Partly cloudy. Chance of a shower or thunderstorm early, favoring eastern areas. Lowering humidity. Lows 60-66. Wind W 5-15 MPH, higher gusts.
THURSDAY: Partly cloudy. Slight chance of an isolated shower or thunderstorm. Highs 75-83. Wind NW 5-15 MPH.
FRIDAY: Sun to clouds. Lows in the 50s. Highs from the upper 70s to middle 80s.
SATURDAY: Clouds to sun. Lows in the 60s. Highs in the 80s.

DAYS 6-10 (AUGUST 26-30)
Summer pattern dominates with high pressure in general control, but surface boundaries and energy from the jet stream not too far to the north can help trigger showers and thunderstorms a few times during this period as well.

DAYS 11-15 (AUGUST 31-SEPTEMBER 4)
General pattern remains the same but will have to watch for a quick cooler interlude of high pressure moving across Canada noses southward far enough.

7:27AM

DAYS 1-5 (AUGUST 20-24)
The cooler interlude has 2 more days to go, then a warm front brings showers Tuesday night and early Wednesday, returning the humidity to the region. A cold front will cross the region Wednesday with a few showers/thunderstorms and that will be the one humid day of this week. Though it will be warmer Thursday and Friday than today and Tuesday, somewhat drier air will again return to the region. The only change from yesterday’s forecast is to add the risk of an isolated shower Thursday as a disturbance crosses the region behind the cold front from the day before. Forecast details…
TODAY: Mostly cloudy to partly sunny. Slight risk of a South Coast shower. Highs 68-76, coolest coastal areas. Wind E 5-15 MPH.
TONIGHT: Mostly cloudy. Lows 57-64. Wind E 5-15 MPH.
TUESDAY: Mostly cloudy to partly sunny. Highs 68-76, coolest coastal areas. Wind E 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Showers likely and a slight risk of a thunderstorm especially after midnight. Increasingly humid. Lows 62-68. Wind SE to S 5-15 MPH.
WEDNESDAY: Variably cloudy. Showers likely early, then isolated to scattered showers/thunderstorms. Humid. Highs 78-86. Wind SW 10-20 MPH.
THURSDAY: Partly cloudy. Isolated showers or thunderstorms possible. Less humid. Lows in the 60s. Highs from the upper 70s to middle 80s.
FRIDAY: Sun followed by clouds. Lows from the upper 50s to middle 60s. Highs from the upper 70s to lower 80s, coolest coast.

DAYS 6-10 (AUGUST 25-29)
During this period a transition back to a hotter pattern will take place as high pressure ridges from the Midwest and the eastern Atlantic merge. Though we will see more humidity again, at the moment it doesn’t look like it will be as oppressive as recent days have been. Rain chances will be more limited overall, but cannot rule out a few showers and thunderstorms at times as a couple disturbances get close to the region.

DAYS 11-15 (AUGUST 30-SEPTEMBER 3)
Current indications are for a hot end of August and start of September, with limited shower and thunderstorm opportunities as high pressure dominates.
