Friday Forecast

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.

Thursday Forecast

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.

Wednesday Forecast

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.

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.

Monday Forecast

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.

Sunday Forecast

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.

Saturday Forecast

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.

Friday Forecast

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.

Thursday Forecast

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.

Wednesday Forecast

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.
