DAYS 1-5 (SEPTEMBER 16-20)

High pressure continues its influence on our weather with fair and warm conditions early this week, but you’ll notice some increasing high cloudiness from the south later today and especially Tuesday. This is fanning off low pressure that is organizing off the US Southeast Coast and moving onshore into the Carolinas. By Wednesday, we lose our high pressure area but because of the blocking still in place in the atmosphere, the low to the south isn’t going to come up the coast that much. It just drifts up in this direction for a while – enough to thicken the clouds and spread some of its rain into at least the South Coast region by late Wednesday. How far north this comes is still in question, but the region overall stands the greatest chance of seeing wet weather from this system Wednesday night and Thursday. By Friday, we’ll already see high pressure from the north regaining control and starting to push this system back out to the south. During mid to late week we’ll have transitioned from our current warmth to a cooler regime…

TODAY: Sun – filtered by the arrival of high clouds from south to north later. Highs 78-85, coolest South Coast. Wind variable to SE up to 10 MPH.

TONIGHT: High cloudiness spreads across the sky. Patchy ground fog interior lower elevations. Lows 51-58. Wind SE to S under 10 MPH.

TUESDAY: Sun – dimmed by the thickening of high clouds south to north. Highs 77-84, coolest South Coast. Wind S up to 10 MPH.

TUESDAY NIGHT: Mostly cloudy. Patchy fog. Lows 54-61. Wind S up to 10 MPH.

WEDNESDAY: Mostly cloudy. Potential rain South Coast by late-day. Highs 74-81. Wind SE 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Potential rain, greatest chance South Coast. Areas of fog. Lows 58-65. Wind E 5-15 MPH.

THURSDAY: Mostly cloudy. Periodic rain is most likely from the I-90 belt southward. Highs 66-73. Wind E 5-15 MPH, higher gusts South Coast.

THURSDAY NIGHT: Clouds linger. Rain chance may hang on South Coast. Lows 51-58. Wind NE 5-15 MPH.

FRIDAY: Cloud / sun mix. Highs 63-70. Wind NE 5-15 MPH, higher gusts at the coast.

DAYS 6-10 (SEPTEMBER 21-25)

Canadian high pressure is expected to be strong enough to provide dry but cooler weather for the September 21-22 weekend. We welcome autumn with the equinox at 8:43 a.m. on September 22. Pattern looks dry and milder early next week, but another surge of wet weather may make a run at the region from the southward around the middle of next week – something to watch.

DAYS 11-15 (SEPTEMBER 26-30)

Indications are for high pressure domination – mainly fair weather, a cool push then a moderating trend.

DAYS 1-5 (SEPTEMBER 15-19)

The temperature and dew point had an overnight meeting, resulting in fog in many areas. Other areas that didn’t fog in may see a blanket of low clouds to start the day, while sun was already visible at sunrise in some spots. The most extensive cloud and fog area at sunrise resided just inland from the eastern coast and had its western limit about where yesterday’s sea breeze stopped progressing inland. Any fog and low clouds will burn away by mid to late morning, leaving us with a sunny midday and afternoon. The coast will be coolest today as an onshore wind evolves, but overall it will be a mild to warm day. High pressure delivers late summer warmth and fair weather Monday and Tuesday. It is at midweek when we finally see enough give in the high pressure area to allow low pressure, and some of its wet weather, to move up from the south. This will bring some increased wind and an episode or two of rain to parts of the region, favoring southern areas. The best chance time window currently appears to be from Wednesday evening to midday Thursday. I’ll fine-tune this in upcoming blog posts.

TODAY: Areas of fog / low clouds early to mid morning, then mainly sunny. Highs 75-82, coolest coast. Wind variable up to 10 MPH, mostly E to SE.

TONIGHT: Mostly clear. Patchy fog interior lower elevations. Lows 51-58. Wind variable under 10 MPH.

MONDAY: Mostly sunny. Highs 78-85. Wind variable up to 10 MPH.

MONDAY NIGHT: Mostly clear. Patchy fog interior lower elevations. Lows 52-59. Wind variable under 10 MPH.

TUESDAY: Partly cloudy. Highs 78-85. Wind SW up to 10 MPH.

TUESDAY NIGHT: Partly cloudy. Patchy fog. Lows 54-61. Wind S up to 10 MPH.

WEDNESDAY: Variably cloudy. Potential rain South Coast by late-day. Highs 68-75. Wind SE 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Potential rain, greatest chance South Coast. Areas of fog. Lows 58-65. Wind E 5-15 MPH.

THURSDAY: Mostly cloudy to partly sunny. Chance of rain in the morning, favoring the South Coast. Highs 65-72. Wind NE 10-20 MPH.

DAYS 6-10 (SEPTEMBER 20-24)

Similar pattern continues with some blocking in the atmosphere. High pressure from eastern Canada delivers drier, cooler weather early in the period before sinking to the south and allowing a warm up mid period, then potentially giving with a wet weather chance from the south late period.

DAYS 11-15 (SEPTEMBER 25-29)

Wash / rinse / repeat .. same pattern delivers another cooler push from Canada that then gives way to later-period warm-up.

DAYS 1-5 (SEPTEMBER 14-18)

High pressure is reinforced from Quebec this weekend as a weak front has pushed through the region. This will turn the wind more northeasterly today, but not very strong, so we’ll still see pretty mild to warm air, just a slight cooling trend the next couple days, most notable in coastal areas. This particular high is not tapping a very cool air mass as that has shifted west for the time being. It’s just a continuation of the blocking pattern that’s keeping our region dry and South and Southeast unsettled, including the remains of Francine. The earliest we have a chance of seeing any of that moisture come this far north would be the end of this 5-day forecast period – Wednesday – and even that is not a very significant chance, which is higher toward the South Coast than anywhere else. I’ll monitor that part of the outlook. Otherwise it’s dry weather, and even another warm-up early in the week as we roll through the late days of summer 2024.

TODAY: Mostly sunny. Highs 75-82, coolest coast. Wind N to E up to 10 MPH.

TONIGHT: Mostly clear evening. Areas of low clouds and fog overnight. Lows 51-58. Wind variable under 10 MPH.

SUNDAY: Early fog / low clouds in some areas. Otherwise mostly sunny. Highs 75-82, coolest coast. Wind variable to NE up to 10 MPH.

SUNDAY NIGHT: Mostly clear. Patchy fog interior lower elevations. Lows 51-58. Wind variable under 10 MPH.

MONDAY: Mostly sunny. Highs 78-85. Wind variable up to 10 MPH.

MONDAY NIGHT: Mostly clear. Patchy fog interior lower elevations. Lows 52-59. Wind variable under 10 MPH.

TUESDAY: Mostly sunny. Highs 78-85. Wind SW up to 10 MPH.

TUESDAY NIGHT: Partly cloudy. Patchy fog. Lows 54-61. Wind S up to 10 MPH.

WEDNESDAY: Variably cloudy. Potential showers South Coast. Highs 68-75. Wind SE 5-15 MPH.

DAYS 6-10 (SEPTEMBER 19-23)

The potential for humid weather and showers exists early in the period, but will depend on how much give there is in a high pressure area and as a result how far north moisture can make it. The trend after is dry and cooler from eastern Canadian high pressure. Autumnal equinox is 8:43 a.m. September 22.

DAYS 11-15 (SEPTEMBER 24-28)

There may be a renewed push of moisture and warmer air from the south with some wet weather chances returning at some point during this period. A lot of details to work out in the battle between that and drier air from the north as the ongoing large scale pattern doesn’t change all that much.

DAYS 1-5 (SEPTEMBER 13-17)

Happy Friday the 13th! If you used today as a day to extend your weekend or otherwise have the day off from your usual daily toil, it’s your lucky day! We’re going to see plenty of sun and temperatures that climb enough to give the feel of mid summer for several hours. As a cold front approaches from the north late in the day, some clouds will start to develop, and a couple of them can build enough to produce a spot shower or thunderstorm mainly in southern NH and far northern MA by the end of the day, but this chance is low and any activity would be isolated with the extreme majority of our region seeing none of that. Any that do pop up will fade this evening and the frontal boundary will continue southward through our region with just some clouds. Another thing you’ll notice today is the hazy look to the sky and filtered nature of the sunshine, and this is once again due to a plume of wildfire smoke from both Canada and the western US as fire season goes on. Overnight, some foggy areas can develop as the temperature drops to meet a dew point that did rise a little bit off recent much lower values. You may notice that today, if you’re sensitive to humidity, that the dew point has climbed to around 60. High pressure will continue to be the mainly player in our weather this weekend and early next week as well. While the weekend will be slightly cooler than today will be, especially along the coast with an easterly component to the wind due to the high to the north, we will continue to see temperatures running above normal, and this warmer spell will also continue into the beginning of next week.

TODAY: Some cloudiness around eastern MA and RI during early morning, otherwise sunshine filtered by high and mid level wildfire smoke. Additional clouds pop up later with a slight chance of a shower or thunderstorm across southern NH and far northern MA by late afternoon. Highs 80-87. Dew point heads to near 60. Wind S up to 10 MPH.

TONIGHT: Some clouds early then clearing, but patchy fog forming later. Lows 56-62. Wind W up to 10 MPH.

SATURDAY: Mostly sunny. Highs 75-82, coolest coast. Wind N to E up to 10 MPH.

SATURDAY NIGHT: Mostly clear. Patchy fog interior lower elevations. Lows 51-58. Wind variable under 10 MPH.

SUNDAY: Mostly sunny. Highs 75-82, coolest coast. Wind variable to E up to 10 MPH.

SUNDAY NIGHT: Mostly clear. Patchy fog interior lower elevations. Lows 51-58. Wind variable under 10 MPH.

MONDAY: Mostly sunny. Highs 76-83. Wind variable up to 10 MPH.

MONDAY NIGHT: Mostly clear. Patchy fog interior lower elevations. Lows 52-59. Wind variable under 10 MPH.

TUESDAY: Mostly sunny. Highs 77-84. Wind SW up to 10 MPH.

DAYS 6-10 (SEPTEMBER 18-22)

On the larger scale, we don’t completely lose the blocking pattern we have, but it can adjust enough to allow some of the moisture held to our south to make its way to north, to introduce higher humidity and a shower chance by the middle of next week. Some guidance shows this while other guidance does not, but the possibility is there, so for now it’ll be part of the outlook. Later next week the indications are for another stronger push of high pressure from eastern Canada and dry weather and a slight cool-down. Monitoring the trends and eventually will be able to provide more detail. One thing we know for sure: Autumnal equinox is 8:43 a.m. September 22.

DAYS 11-15 (SEPTEMBER 23-27)

The general trend is for high pressure to be in control most of the time with a dry and fairly mild pattern (though a push of cooler Canadian air is possible for a portion of the period).

DAYS 1-5 (SEPTEMBER 12-16)

A large scale block remains in place with high pressure dominating our weather through the weekend and into the beginning of next week too. The only change to take place is the dominant high regarding our weather will shift from one to our south today and Friday to one in Quebec thereafter. Between the 2 a dry cold frontal passage will take place early Saturday. Temperatures that warm to mid summer levels by tomorrow get knocked back a little bit over the weekend, but we’ll still be in a very mild pattern.

TODAY: Mostly sunny. Highs 78-85. Wind SW 5-15 MPH.

TONIGHT: Clear. Interior lower elevation fog patches. Lows 54-61. Wind SW up to 10 MPH.

FRIDAY: Mostly sunny. Highs 81-88, maybe a little cooler along the South Coast. Wind SW 5-15 MPH.

FRIDAY NIGHT: Mostly clear evening. Partly cloudy overnight. Lows 56-62. Wind W 5-15 MPH.

SATURDAY: Partly cloudy morning. Mostly sunny afternoon. Highs 72-82. Wind NW to NE 5-15 MPH.

SATURDAY NIGHT: Mostly clear. Patchy fog interior lower elevations. Lows 51-58. Wind variable under 10 MPH.

SUNDAY: Mostly sunny. Highs 75-82, coolest coast. Wind variable to NE up to 10 MPH.

SUNDAY NIGHT: Mostly clear. Patchy fog interior lower elevations. Lows 51-58. Wind variable under 10 MPH.

MONDAY: Mostly sunny. Highs 76-83. Wind variable up to 10 MPH.

DAYS 6-10 (SEPTEMBER 17-21)

The large scale pattern will continue to feature some blocking in the atmosphere, with high pressure remaining in control of our weather early to mid next week. Later in the week a more southerly air flow will allow more humidity to arrive and a chance of some shower activity – details TBD. Temperatures near to above normal.

DAYS 11-15 (SEPTEMBER 22-26)

The autumnal equinox occurs at 8:43 a.m. on September 22. A little more interaction of moisture from the south and jet stream / cooler air masses from the north means a better shot at some shower activity at times and somewhat variable temperatures. Far too soon for daily details.

DAYS 1-5 (SEPTEMBER 11-15)

A blocking pattern keeps high pressure in place through late week, with fair weather and a warming trend. A dry cold front passages and a new high pressure area in Quebec will keep the weather fair but a touch cooler for the weekend.

TODAY: Sunny. Highs 75-82. Wind SW 5-15 MPH.

TONIGHT: Clear. Interior lower elevation fog patches. Lows 52-59. Wind SW up to 10 MPH.

THURSDAY: Mostly sunny. Highs 78-85. Wind SW 5-15 MPH.

THURSDAY NIGHT: Clear. Interior lower elevation fog patches. Lows 54-61. Wind SW up to 10 MPH.

FRIDAY: Mostly sunny. Highs 81-88, maybe a little cooler along the South Coast. Wind SW 5-15 MPH.

FRIDAY NIGHT: Mostly clear evening. Partly cloudy overnight. Lows 56-62. Wind W 5-15 MPH.

SATURDAY: Partly cloudy morning. Mostly sunny afternoon. Highs 72-79. Wind NW to NE 5-15 MPH.

SATURDAY NIGHT: Mostly clear. Patchy fog interior lower elevations. Lows 51-58. Wind variable under 10 MPH.

SUNDAY: Mostly sunny. Highs 71-78. Wind variable up to 10 MPH.

DAYS 6-10 (SEPTEMBER 16-20)

The large scale pattern will continue to feature some blocking in the atmosphere, with high pressure remaining in control of our weather early to mid next week. Later in the week a more southerly air flow will allow more humidity to arrive and a chance of some shower activity – details TBD. Temperatures near to above normal.

DAYS 11-15 (SEPTEMBER 21-25)

A little more interaction of moisture from the south and jet stream / cooler air masses from the north means a better shot at some shower activity at times and somewhat variable temperatures. Far too soon for daily details. The autumnal equinox occurs at 8:43 a.m. on September 22.

DAYS 1-5 (SEPTEMBER 10-14)

A trough pushes offshore this morning taking any clouds with it. High pressure builds in today with a dry northwest breeze and a few passing clouds amidst plenty of sun. We are then in for a stretch of generally sunny days and clear nights, except patchy ground fog in low elevations were radiational cooling is maximized, with high pressure dominating through Friday. Each afternoon will be warmer than the previous one. Saturday, a weak cold front will move through uneventfully from north to south, other than a few clouds and a shift in the wind direction, resulting in a slight cool-down for the start of the weekend while the weather continues fair.

TODAY: Mostly sunny. Highs 70-77. Wind W 5-15 MPH.

TONIGHT: Clear. Interior lower elevation fog patches. Lows 51-58. Wind SW up to 10 MPH.

WEDNESDAY: Sunny. Highs 75-82. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Clear. Interior lower elevation fog patches. Lows 52-59. Wind SW up to 10 MPH.

THURSDAY: Mostly sunny. Highs 78-85. Wind SW 5-15 MPH.

THURSDAY NIGHT: Clear. Interior lower elevation fog patches. Lows 54-61. Wind SW up to 10 MPH.

FRIDAY: Mostly sunny. Highs 81-88, maybe a little cooler along the South Coast. Wind SW 5-15 MPH.

FRIDAY NIGHT: Mostly clear evening. Partly cloudy overnight. Lows 56-62. Wind W 5-15 MPH.

SATURDAY: Partly cloudy morning. Mostly sunny afternoon. Highs 72-79. Wind NW to NE 5-15 MPH.

DAYS 6-10 (SEPTEMBER 15-19)

The large scale pattern will feature some blocking in the atmosphere, with high pressure remaining in control of our weather at least into early next week. If there’s one larger question to answer, it will be whether or not high pressure remains in place and strong enough to keep tropical moisture – remains of Francine – to our south, or will weaken enough to allow it into the region later in the period. Temperatures near to above normal.

DAYS 11-15 (SEPTEMBER 20-24)

The large scale pattern indications put upper level high pressure further east and introduce a more southerly air flow to our region, increasing the opportunity for higher humidity and wet weather at times. Regardless of the pattern, we will welcome autumn with the equinox at 8:43 a.m. on September 22.

DAYS 1-5 (SEPTEMBER 9-13)

A trough from the west will traverse the region today and tonight, and after a sunny start to the day we’ll have clouds developing / moving in, and they bring the threat of a few passing showers later on, but many of those should stay to the north of the WHW forecast area, before the trough exits overnight. High pressure then controls the weather Tuesday through Friday with fair weather and a warming trend, so the feel of summer is back late this week!

TODAY: Sunny into mid morning, then becoming variably cloudy. Late-day isolated to scattered showers favoring areas north of I-90. Highs 68-75. Wind W 5-15 MPH, a few higher gusts.

TONIGHT: Lots of clouds in the evening with an additional shower possible. Clearing overnight. Lows 50-57. Wind W 5-15 MPH.

TUESDAY: Mostly sunny. Highs 70-77. Wind W 5-15 MPH.

TUESDAY NIGHT: Clear. Interior lower elevation fog patches. Lows 51-58. Wind SW up to 10 MPH.

WEDNESDAY: Sunny. Highs 75-82. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Clear. Interior lower elevation fog patches. Lows 52-59. Wind SW up to 10 MPH.

THURSDAY: Mostly sunny. Highs 78-85. Wind SW 5-15 MPH.

THURSDAY NIGHT: Clear. Interior lower elevation fog patches. Lows 54-61. Wind SW up to 10 MPH.

FRIDAY: Mostly sunny. Highs 81-88, maybe a little cooler along the South Coast. Wind SW 5-15 MPH.

DAYS 6-10 (SEPTEMBER 14-18)

High pressure in eastern Canada will push a cold front southward through the region sometime early in the weekend, but all that will do is take the edge off the warmth and replace it with mild air with fair weather this weekend. High pressure should control the weather into next week as well with fair weather and near to above normal temperatures. Toward the end of the period we should see a bit more humidity as high pressure slides off to the east and we get into more of a southerly air flow.

DAYS 11-15 (SEPTEMBER 19-23)

The final days of summer may feature higher humidity and some increase in shower chances with a southerly air flow and a trough to the west. Another push of Canadian dry air may arrive to greet the start of Autumn. Equinox 8:43 a.m. on Sunday September 22.

DAYS 1-5 (SEPTEMBER 8-12)

Low pressure passes to our north today but to its south, we’ll be in a westerly flow of dry air with fair weather. We still have upper level low pressure to pass north of us with some cyclonic flow in the jet stream through Monday. With a little less suppressive dry air Monday, and the approach of a trough, we’ll see more in the way of diurnal clouds popping up after today is a sunnier day with less in the way of diurnal cloud development. By Tuesday, this feature is beyond our region and high pressure builds in, then slides to the south and east, with fair weather and a warming trend through midweek.

TODAY: Sunny morning. Sun and passing clouds afternoon. Highs 68-75. Wind W 5-15 MPH, few higher gusts.

TONIGHT: Mainly clear. A fog patch can form over interior lower elevations. Lows 47-54, coolest interior low spots. Wind W under 10 MPH.

MONDAY: Sunny early, then intervals of sun and clouds. Highs 68-75. Wind W 5-15 MPH, a few higher gusts.

MONDAY NIGHT: Partly cloudy evening. Clear overnight. Lows 47-54. Wind NW 5-15 MPH.

TUESDAY: Mostly sunny. Highs 70-77. Wind W 5-15 MPH.

TUESDAY NIGHT: Clear. Interior lower elevation fog patches. Lows 51-58. Wind SW up to 10 MPH.

WEDNESDAY: Sunny. Highs 75-82. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Clear. Interior lower elevation fog patches. Lows 52-59. Wind SW up to 10 MPH.

THURSDAY: Sunny. Highs 78-85. Wind SW 5-15 MPH.

DAYS 6-10 (SEPTEMBER 13-17)

High pressure brings fair and mild to warm weather much of this period but may yield to unsettled weather briefly by late period.

DAYS 11-15 (SEPTEMBER 18-22)

The large scale pattern still indicates a tendency to be dry overall, but there are some signs of a more southerly air flow, higher humidity, and increased shower chances on some medium range guidance. NOTE however that even with the typical uncertainty in this time frame, there’s been a lot of inconsistency on guidance, rendering it even less reliable than would be usual for this time distance.

DAYS 1-5 (SEPTEMBER 7-11)

There is only one bout of unsettled weather for us to deal with during the next 5 days and it is sandwiching itself in between the daytime hours of the weekend. While a pretty potent storm tracks northward, passing east of our region and heading into Atlantic Canada, a trough from the west will push a front west to east through the region tonight. The impacts from these systems are rough surf and rip currents along the coast today from the offshore storm, and about a 6 to 8 hour window-of-chance for showers from west to east tonight (generally 8 p.m. to 4 a.m.). Sunday, we return to low humidity and pleasant, though breezy weather as low pressure from the west passes to our north. High pressure then controls the weather with fair weather and a warming trend early to mid next week.

TODAY: Variably cloudy. Highs 70-77. Wind variable up to 10 MPH.

TONIGHT: Mostly cloudy. Showers likely 8 p.m. to 4 a.m. from west to east. Fog patches form overnight. Lows 58-65. Wind S 5-15 MPH shifting to west.

SUNDAY: Sun and passing clouds. Highs 68-75. Wind W 5-15 MPH, gusty.

SUNDAY NIGHT: Clear. Lows 47-54. Wind W 5-15 MPH.

MONDAY: Mostly sunny. Highs 68-75. Wind W 5-15 MPH.

MONDAY NIGHT: Clear. Lows 51-58. Wind W up to 10 MPH.

TUESDAY: Sunny. Highs 74-81. Wind W 5-15 MPH.

TUESDAY NIGHT: Clear. Lows 52-59. Wind SW up to 10 MPH.

WEDNESDAY: Sunny. Highs 76-83. Wind SW 5-15 MPH.

DAYS 6-10 (SEPTEMBER 12-16)

High pressure brings fair and mild to warm weather much of this period but may yield to unsettled weather briefly by late period.

DAYS 11-15 (SEPTEMBER 17-21)

The final 5 full days of summer will feature a generally dry pattern overall with temperatures near to mostly above normal. A minor interruption or two can occur with passing weak systems but no major storminess indicated.

DAYS 1-5 (SEPTEMBER 6-10)

The high pressure area that has given us a stretch of fair weather is losing its control, having slipped off to the east, allowing some low level moisture in the form of low clouds into the region overnight, so many places start with a grey sky today and only break for partial sun during the day. Deepening low pressure in the Atlantic southeast of New England will track north northeastward, passing well to our east later today and early Saturday. Other than being part of an air flow that adds more clouds to our sky, this system will serve to increase the surf along the coast into the weekend, so keep this in mind if you have beach / boating plans. A trough to our west will send a frontal boundary eastward through the region Saturday night, bringing some rain showers to the region from west to east mainly late evening (west) and overnight (east). This system will move quickly enough so that it exits around sunrise Sunday, setting up a nice finish to the weekend with more sun, drier air, and a gusty breeze, after a Saturday that features more clouds and will be a little humid, although not really bad at all. High pressure builds in early next week with fair weather and a warming trend.

TODAY: Mostly cloudy to partly sunny. Highs 69-76, coolest along the coast. Wind E up to 10 MPH.

TONIGHT: Partly to mostly cloudy. Patchy fog. Lows 55-62. Wind NE up to 10 MPH inland, 15 MPH coast.

SATURDAY: Mostly cloudy to partly sunny. Highs 70-77, coolest Cape Cod. Wind N 5-15 MPH, higher gusts at times along the coast through midday.

SATURDAY NIGHT: Mostly cloudy. Patchy fog and a chance of showers late evening and overnight. Lows 58-65. Wind variable to S 5-15 MPH.

SUNDAY: Sun and passing clouds. Highs 68-75. Wind W 5-15 MPH, gusty.

SUNDAY NIGHT: Clear. Lows 47-54. Wind W 5-15 MPH.

MONDAY: Mostly sunny. Highs 68-75. Wind W 5-15 MPH.

MONDAY NIGHT: Clear. Lows 51-58. Wind W up to 10 MPH.

TUESDAY: Sunny. Highs 72-82. Wind W 5-15 MPH.

DAYS 6-10 (SEPTEMBER 11-15)

High pressure brings fair and mild to warm weather much of this period but may yield to unsettled weather late period.

DAYS 11-15 (SEPTEMBER 16-20)

Similar pattern, high pressure returns with mostly fair weather and watch for an unsettled interruption or 2, but nothing long-lasting.

DAYS 1-5 (SEPTEMBER 5-9)

High pressure sits overhead now, then drifts off to our east through Friday. We’ll see abundant sun today and some increase in clouds on Friday, but both days will be quite nice in general, even though humidity starts to climb a little on Friday. This weekend has a bit of complexity thrown into the forecast but turns out ok despite two foul weather systems making runs at our region. The first will be a deepening offshore storm center that will track northward, passing to our east, but close enough to be responsible for a lot of the clouds we see moving in on Friday, and perhaps a few showers skirting Cape Cod late Friday night or early Saturday morning (for now I am keeping these out of the detailed forecast). This system will stir up some rough surf along the coast to start the weekend, so keep that in mind if you have late summer beach / boating plans. Additionally, a couple plumes of high altitude wildfire smoke will give the sky that hazier look at times the next few days. The second system is a trough from the west which will send a front through from west to east, bringing a shower threat over about a 6 to 8 hour time window sometime Saturday night and early Sunday, greatest chance during the overnight hours. This will be followed by a wind shift to west and drier, improved weather during the day Sunday, which continues Monday as high pressure builds in.

TODAY: Sunny. Highs 71-78. Dew point in 50s. Wind variable up to 10 MPH.

TONIGHT: Partly cloudy. Patchy fog. Lows 53-60. Dew point in 50s. Wind S under 10 MPH.

FRIDAY: Partly sunny. Highs 72-79, coolest coast. Dew point in 50s. Wind S to SE up to 10 MPH.

FRIDAY NIGHT: Mostly cloudy. Patchy fog. Lows 55-62. Dew point middle to upper 50s. Wind E 5-15 MPH, most notable along the coast.

SATURDAY: Variably cloudy. Highs 71-78. Dew point rising to lower 60s. Wind NE to N 5-15 MPH, most notable along the coast through midday.

SATURDAY NIGHT: Mostly cloudy. Chance of showers overnight. Areas of fog. Lows 58-65. Dew point upper 50s to lower 60s. Wind variable to S 5-15 MPH.

SUNDAY: Variably cloudy with patchy fog and a chance of showers early, then a sun/cloud mix. Highs 68-75. Dew point falling through the 50s. Wind shifting to W 5-15 MPH, higher gusts possible.

SUNDAY NIGHT: Clear. Lows 47-54. Dew point falling into 40s. Wind W 5-15 MPH.

MONDAY: Mostly sunny. Highs 66-73. Dew point in 40s. Wind W 5-15 MPH.

DAYS 6-10 (SEPTEMBER 10-14)

High pressure brings generally dry weather with a cool start then a warming trend during much of next week.

DAYS 11-15 (SEPTEMBER 15-19)

Increased chances for more humid and potentially showery weather early to mid period before a drier, cooler weather returns.

DAYS 1-5 (SEPTEMBER 4-8)

High pressure will continue its control over the weather with fair conditions, cool nighttimes and mild daytimes during the next few days. While sunshine is abundant today and Thursday, it will have to share the sky with more clouds on Friday as a southeasterly air flow becomes more established and transports more low level moisture into the region. The setup for the weekend still indicates two low pressure systems that will not interact enough to bring significant wet weather, allowing much of the weekend to be rain-free. Low pressure will pass well southeast to east of New England early in the weekend, while a trough of low pressure moves into the Great Lakes. The system to the west will send a frontal boundary eastward to produce a round of shower activity at some point during the weekend. The current indications are that the window of time for these will be approximately 12 hours between late Saturday night and the middle of Sunday, but will obviously be tweaked as needed as we approach that time.

TODAY: Sunny. Highs 70-77. Dew point in 40s. Wind W up to 10 MPH.

TONIGHT: Clear. Ground fog patches possible. Lows 43-50 except milder urban centers. Dew point lower to middle 40s. Wind calm.

DAYS 6-10 (SEPTEMBER 9-13)

Next week looks quiet with high pressure in control – starting out with near to below normal temperatures followed by a moderating trend.

DAYS 11-15 (SEPTEMBER 14-18)

Fairly dry pattern with limited shower chances and temperatures generally around typical values for mid September. Some guidance in medium range has hinted at more moisture from the south later in this period, but only something to monitor, trend-wise, for now.

DAYS 1-5 (SEPTEMBER 3-7)

High pressure brings fair weather, chilly nights and mild days through midweek before humidity nudges up a tad with a warming trend late week. Previously, guidance was fairly strongly indicating low pressure from the south and a trough from the west trying to combine for a wet Saturday, but solid guidance trends toward stronger high pressure and two more separate systems lead me to declare Saturday to have a rain-free outlook just more cloudiness and higher humidity, but not a bad start to the weekend. Continuing to monitor the evolution for any other changes…

DAYS 6-10 (SEPTEMBER 8-12)

Low pressure looks like it will pass well to the southeast of the region, staying separate from a trough from the west, which will be running into blocking high pressure and weakening, with just a shower chance to end the weekend on September 8 as it stands now. Remainder of the period looks fairly dry, shifting to cooler then moderating again late in the period.

DAYS 11-15 (SEPTEMBER 13-17)

Pattern looks quiet and slightly warmer mid month.

DAYS 1-5 (SEPTEMBER 2-6)

A cold front moves offshore and a clearing trend takes over with a decent holiday Monday today – dry weather and lower humidity. High pressure builds in with fair weather continuing through the shortened work / school week, starting out cool Tuesday with chilly nights and warmer days midweek and then slightly higher humidity by the end of the week as the high center will have traversed the Northeast and pushed offshore to the east.

DAYS 6-10 (SEPTEMBER 7-11)

A trough from the west and low pressure from the south bring a wet weather threat at some point during the September 7-8 weekend, but magnitude of wet weather threat and timing are uncertain and will be focused on and fine-tuned during the week. Fair weather pattern returns after. Temperatures near to slightly below normal.

DAYS 11-15 (SEPTEMBER 12-16)

Pattern looks quiet and somewhat warmer mid month.
