DAYS 1-5 (SEPTEMBER 15-19)

I had to chuckle a tad when I woke up early this morning to a feel-of-fall chill coming through the window via Canada while at the same time seeing the early sunlight filtered through the canopy of high clouds from a weather system that originated deep in the tropics. After how humid we had been, and how humid we are currently not, it was just a little funny. But weather is often about interaction between things that originate far from each other, and this will be the case for us the next couple days as Lee, during transition from hurricane, to tropical storm, to post-tropical, will make its northward trek just to our east and make a post-tropical landfall Saturday afternoon in western Nova Scotia. We’ll have a generally nice day today under the clouds, which will limit our sun, but maybe set up a nice sunset later before they thicken up tonight. Lee’s impacts will be limited mostly to rough surf along the coast, with north-facing shores most vulnerable to high tide flooding late tonight and midday Saturday. The wind will be the other most noticeable impact, with a fresh northerly breeze on the western fringe of the storm’s circulation. I’m expecting peak wind gusts of 25-35 MPH over interior areas, 35-45 MPH over the coastal plain, but 45-55 MPH along the immediate coast with 55 MPH + wind gusts possible on the tip of Cape Ann and across Cape Cod and Nantucket. As Lee pulls away Saturday afternoon, the winds will begin to diminish. The rainfall impact from Lee’s passage will be rather limited. The rain shield should expand northwestward from offshore, reaching Cape Cod and Nantucket by 10PM or so, Boston area by about 2AM, and out as far as the I-95 and I-495 belts possibly by just before dawn. But the further west you are, the less likely you are to see any rain and if you do the shorter-lived it will likely be. Dry air in place will chomp up the western fringe of the rain area. For rain amounts, expect traces inland, about 0.10 tops near the NH Seacoast and MA North Shore through Boston area, up to 0.50 inch near the Cape Cod Canal, and 1.00 inch or more from Mid Cape eastward. That’s it. And then Lee’s outta here late Saturday with rapid improvement, maybe another nice sunset for parts of the region, a cool Saturday night with dry air reinforce, and a pleasant Sunday with lots of sun, passing clouds, and dry air. Monday’s weather briefly tanks as a low pressure trough swings through the region with showery conditions – timing to be fine-tuned next updates. This should move swiftly enough so we’re right back to fair by Tuesday.

TODAY: Limited sun – lots of high clouds. Highs 66-73. Wind N 5-15 MPH.

TONIGHT: Thickening clouds. Rain arrives southeast to northwest overnight, steadiest Cape Cod and coastal areas. Lows 55-62. Wind N increasing to 10-20 MPH with gusts 25 MPH or higher inland, 15-25 MPH with gusts 35 MPH or higher coastal plain, and 25-35 MPH with gusts 45 MPH or higher immediate coast, strongest gusts Cape Cod and Nantucket as well as tip of Cape Ann.

SATURDAY: Cloudy through midday including rain likely Cape Cod and a chance of rain eastern MA & NH Seacoast, then increasing sun especially western areas during the afternoon and maybe into eastern areas later on. Highs 66-73. Wind in the morning N increasing to 10-20 MPH with gusts 25 MPH or higher inland, 15-25 MPH with gusts 35 MPH or higher coastal plain, and 25-35 MPH with gusts 45 MPH or higher immediate coast, strongest gusts Cape Cod and Nantucket as well as tip of Cape Ann. Wind in the afternoon shifting to NW and diminishing.

SATURDAY NIGHT: Clearing. Lows 51-58. Wind NW 5-15 MPH.

SUNDAY: Mostly sunny. Highs 68-75. Wind NW 5-15 MPH.

SUNDAY NIGHT: Increasing clouds. Lows 50-57. Wind W up to 10 MPH.

MONDAY: Mostly cloudy. Showers likely. Highs 67-74. Wind variable to S 5-15 MPH.

MONDAY NIGHT: Clearing. Lows 50-57. Wind W 5-15 MPH.

TUESDAY: Sun/cloud mix. Highs 65-72. Wind NW 5-15 MPH.

DAYS 6-10 (SEPTEMBER 20-24)

High pressure controls the weather through mid period as we wrap up summer 2023 and welcome autumn with the equinox on September 23. By the end of the period we may be looking to our south at approaching tropical moisture and increased cloudiness and possibly more wet weather.

DAYS 11-15 (SEPTEMBER 25-29)

A wet weather chance may exist early in the period before high pressure re-takes control with a generally dry and mild pattern for late September.

DAYS 1-5 (SEPTEMBER 14-18)

A cold front will complete its trip across our region by moving offshore later this morning / midday, putting an end to the last of the showers currently (as of 7 a.m.) over far southeastern MA. While some other clouds may stream across the sky from southwest to northeast in the mid and upper level winds behind the front, the balance of the day is going to feature fair weather, mild air, and the arrival of much lower humidity. Ah! This drier air mass will hang around for a while too, and will actually be a player to some degree in our Saturday forecast, regarding Lee’s passage. First, we’ll enjoy a nice day on Friday as high pressure sits over the Great Lakes and sends us nice Canadian air on a northwesterly wind. As this happens, Hurricane Lee will be making its way northward, accelerating, and weakening, but also expanding in size as it begins the process of tropical to post-tropical transition. Lee will still be at hurricane strength on Friday and on its projected path it will make its closest pass to our region during the first two thirds of the day Saturday, the center still well offshore. An interaction with a low pressure trough to our west will give Lee’s path a little wiggle to the west, just enough to bring its expanded wind field into our area, of course strongest along the coast, especially Cape Cod. The cloud shield associated with Lee will already have started to spread north and northwest into our region later Friday, reaching its maximum Saturday morning to midday. This is also when Lee’s rain shield has the greatest chance of impacting the region. The most likely location to see any appreciable rainfall is Cape Cod. While the rain shield may make its way across the coastal plain and possibly as far as the I-95 and maybe even briefly the I-495 belts, it will also be battling the aforementioned dry air in place over our region, which will eat away at the western edge of it. Essentially, rainfall from Lee will be a non-factor except for on Cape Cod. The other more important factor, already ongoing and continuing through Saturday, will be the rough surf and large ocean swells along the coastline. As previously mentioned, use caution if you have plans that take you sea-side or into the coastal waters during the next few days, through the weekend. Although by Sunday and definitely Monday these conditions will be subsiding. My expectation for Lee is that he will have weakened to a tropical storm during the transition to post-tropical while passing our latitude and make a landfall as an “almost” post-tropical storm on the western side of Nova Scotia later Saturday, before heading off through Atlantic Canada as a gusty wind and rain storm. Keep in mind that well-in-advance nice sunset prediction for our region late Saturday. We may be able to add Friday to that prediction depending on the advancing cloud shield ahead of Lee. But at least one of those is going to produce nicely. Hold me to it! Our weather improves quickly Saturday evening and is stellar for Sunday with fair weather, low humidity, and a tolerable breeze. A trough from the west moves in for Monday with more clouds and the chance of some rainfall again in the region, but at this time it does not look like a heavy rainfall event.

TODAY: Clouds and showers linger in the Cape Cod region for a while this morning. Otherwise, a sun/cloud mix. Highs 71-78. DP falling 60s to 50s. Wind W 5-15 MPH.

TONIGHT: Clearing. Lows 55-62. DP ~ 50. Wind WNW 5-15 MPH.

FRIDAY: Sun, but clouds increasing later in the day from southeast to northwest. Highs 68-75. DP ~ 50. Wind NW 5-15 MPH.

FRIDAY: Cloudy. Rain arrives Cape Cod. Lows 57-64. DP lower-middle 50s rising to near 60 Cape Cod. Wind N 5-15 MPH inland, 15-30 MPH coast, higher gusts.

SATURDAY: Cloudy through midday including rain likely Cape Cod and a chance of rain eastern MA & NH Seacoast, then increasing sun especially western areas during the afternoon and maybe into eastern areas later on. Highs 66-73. DP middle 50s to lower 60s, highest coast, falling again later. Wind N 10-20 MPH inland, 20-35 MPH coast, strongest Cape Cod, including higher gusts through midday, diminishing gradually thereafter.

SATURDAY NIGHT: Clearing. Lows 50-57. DP falling to 40s. Wind NW 5-15 MPH.

SUNDAY: Mostly sunny. Highs 68-75. DP 40s. Wind NW 5-15 MPH.

SUNDAY NIGHT: Increasing clouds. Lows 50-57. DP upper 40s. Wind W up to 10 MPH.

MONDAY: Mostly cloudy. Showers likely. Highs 67-74. DP rising to near 60. Wind variable to S 5-15 MPH.

DAYS 6-10 (SEPTEMBER 19-23)

High pressure establishes control as we count down the final days of summer to the arrival of Autumn (equinox September 23) with a long stretch of mainly fair weather and temperatures near to slightly above normal.

DAYS 11-15 (SEPTEMBER 24-28)

While lower confidence further out, the indications are for high pressure to be dominant with a mainly dry pattern and temperatures near to above normal.

DAYS 1-5 (SEPTEMBER 13-17)

A long-talked about trough and associated frontal system will enter our region from the west today and take until sometime Thursday morning to completely pass across the region. This allows high humidity to continue along with a couple or a few rounds of showers and thunderstorms, generally arranged in broken lines or clusters, the first from late morning too early afternoon, the second later this afternoon to early this evening, and a likely third round in the early morning hours of Thursday over southeastern MA (maybe part of RI) lingering on Cape Cod as late as mid morning Thursday. Any or all of these areas could contain an isolated severe storm or to with the emphasis south of I-90. The perimeters are there for even a storm or two with rotation, so that will be something to keep watch for as well. I also know many are concerned with repeated flooding from today’s and tonight’s activity. While heavier showers/storms can result in some additional/renewed flooding problems, these should be more localized and much shorter-lived than the event that took place Monday. As the front passes, a wind shift to northwest, occurring from west to east, will usher in much drier air, but this progression is not rapid, and it will take until midday Thursday for this new air mass to have reached the entirety of the region. Thursday night will give you that feel of autumn in the air, while it’s still technically summer, the days are waning and it’s only a matter of time. But we haven’t felt much of this yet in the late summer days as we’ve been in such a persistent pattern of higher humidity and frequent rainfall events. Speaking of events, while we’re enjoying a comfortable mid September / late summer day on Friday, we’ll be keeping a close eye on Hurricane Lee, which will be in the process of accelerating northward in the waters between Bermuda and southern New England. The track of this system, as usual, has been the hot topic, but some details need to be remembered. These include Lee’s path over cooler water and its encountering of wind shear, and a slightly slower-than-typical acceleration, all which will contribute to a weakening and an early beginning of the transition from tropical to post tropical system. Transitioning systems also expand in size in terms of their wind field, so this has to be taken into account when developing a forecast for our region. My initial ideas for Lee’s eventual path haven’t really changed that much, nor will they here for this forecast. We see the cyclone wavering along its path due to influences from various weather systems in the western Atlantic and eastern North America. This is typical but maybe a little more apparent due to this particular pattern configuration and Lee’s slightly slower movement. But slower movement is still relative, because the system will be accelerating and expanding as it makes its closest pass to us between Friday night and Saturday afternoon. My best guess is that Lee’s landfall will take place between the eastern tip of Maine and the southern tip of Nova Scotia sometime on Saturday evening. What that means for our region is that we get under the cloud canopy of the storm Friday night into Saturday, and a period of stronger northerly wind (on the storm’s back side), especially for the coastal areas / Cape Cod, where it’s not unreasonable to expect gale-force gusts at this point. Does the rain shield on the western side of the storm make it this far west? Good question. It probably does, to some degree, with the greatest chance of rainfall being on Cape Cod. There will also be a significant amount of dry air in place over our region, which tends to eat away at the western sides of these precipitation areas when the storms are passing by like this one will be. So I’m downplaying the rain chance, based on this, and just focusing on the impacts of cloud cover and wind, and probably the most important of all, for coastal areas – rough surf and rip currents, which have already begun and will continue into the weekend as Lee passes by then moves away. The peak for this will likely be the second half of Friday and a good portion of Saturday, so keep this in mind if you have late-season coastal water or beach plans. Is it too early to call for the potential of stunning sunsets on Friday and/or Saturday during the approach of Lee Friday and the departure of Lee Saturday, allowing the setting sun to sneak under the storms cloud deck? Mark it down – let’s see what happens!

TODAY: Some early sun for eastern areas otherwise generally cloudy. Showers and possible thunderstorms midday on. Any storms can produce downpours and localized flooding. Isolated severe storms are possible mainly south of I-90. Highs 71-78. DP 60s. Wind S 5-15 MPH.

TONIGHT: Cloudy. Showers continue and become most likely in RI and southeastern MA. Areas of fog. Lows 61-68. DP 60+. Wind SW up to 10 MPH.

THURSDAY: Clouds and showers linger in the Cape Cod region for a while in the morning. Otherwise, a sun/cloud mix. Highs 71-78. DP falling 60s to 50s. Wind W 5-15 MPH.

THURSDAY NIGHT: Clearing. Lows 55-62. DP ~ 50. Wind WNW 5-15 MPH.

FRIDAY: Sun, but clouds increasing later in the day from south to north, especially in eastern areas. Highs 68-75. DP ~ 50. Wind NW 5-15 MPH.

FRIDAY NIGHT: Mostly cloudy. Lows 55-62. DP lower 50s. Wind N 5-15 MPH except 15-25 MPH Cape Cod with higher gusts.

SATURDAY: Mostly cloudy through midday including a chance of rain Cape Cod. Sun may shine more, especially western areas, later in the day. Highs 66-73. DP lower 50s. Wind N 10-20 MPH except 15-30 MPH Cape Cod with higher gusts possible.

SATURDAY NIGHT: Clearing. Lows 50-57. DP falling to 40s. Wind NW 5-15 MPH.

SUNDAY: Mostly sunny. Highs 68-75. DP 40s. Wind NW 5-15 MPH.

DAYS 6-10 (SEPTEMBER 18-22)

Next trough brings a chance of some wet weather early next week, before high pressure returns and brings a stretch of dry weather for several days following, starting slightly cooler and drier then with a warming trend as we hit the last couple days of summer

DAYS 11-15 (SEPTEMBER 23-27)

Autumn arrives with the equinox on September 23. The early days of the new season look fairly quiet with a zonal flow pattern, mostly fair weather, a brief shower threat or two, and temperatures near to slightly above normal.

DAYS 1-5 (SEPTEMBER 12-16)

The frontal boundary that was draped over the region yesterday, and a player in what turned out to be two intense rain areas with major flash flooding (Leominster area, North Attleboro area), is washing out in place and what’s left of it will drift offshore today. A nearly indiscernible bubble of high pressure will be just enough to help clouds break for partial sun today, but any sun will help fuel a few pop up showers and a very low risk of a thunderstorm. The good news is today’s activity would not organize into quasi-stationary lines and dump a ton of rain, but would just be smaller single cells or small clusters that would pass by, albeit a bit slowly. We still have a very weak steering flow in this humid atmosphere. But things will change soon. The bad news is to get that change to take place, part of it involves another shower/thunderstorm opportunity Wednesday, mainly afternoon and nighttime, as a cold front moves into the region from the west. This front isn’t an express train by any means, but it is going to moving along at least, just taking its time, so the shower threat persists into the early hours of Thursday before dry air arrives from west to east. This sets up a very nice Thursday afternoon through Friday with a well-deserved break in humid, wet weather. Friday is easily to be the weather pick of the week. Late Friday and Saturday our attention will be on Hurricane Lee as it makes its closest pass to our region. My expectation at the moment hasn’t changed much from my earlier ideas. Yes, we need to watch the storm. It’s going to send at least big waves and heavy surf into our coastal areas. It’ll probably invade eastern portions of the region, at least, with its cloud canopy. For the moment, I think the track of the accelerating / expanding / transitioning storm will be off shore enough that its rain shield will stay over water, making its closest pass during the first half of the day Saturday. If this idea is correct, we’d have a day with clouds overhead, but dry weather, and a gusty breeze on the back side of the passing storm, which will probably be a low end category 1 hurricane or strong tropical storm, in the process of transitioning from tropical to post-tropical. Lee will have been weakened by additional wind shear and a wake cool pool of water left behind by 2 recent hurricanes off the US East Coast.

TODAY: Patchy fog/drizzle early. Lots of clouds, partial sun, and isolated afternoon showers with a slight chance of thunder. Highs 73-80, warmest inland areas. DP upper 60s. Wind variable up to 10 MPH.

TONIGHT: Mostly cloudy. Isolated showers. Patchy fog. Lows 61-68. DP near 60. Wind SE under 10 MPH.

WEDNESDAY: Mostly cloudy. Showers likely and a chance of thunderstorms midday on. Highs 71-78. DP 60s. Wind S 5-15 MPH.

WEDNESDAY NIGHT: Cloudy. Showers continue. Areas of fog. Lows 61-68. DP 60+. Wind SW up to 10 MPH.

THURSDAY: Mostly cloudy early with showers lingering in eastern MA and NH Seacoast regions, then a sun/cloud mix. Highs 70-77. DP falling 60s to 50s. Wind W 5-15 MPH.

THURSDAY NIGHT: Clearing. Lows 55-62. DP ~ 50. Wind WNW 5-15 MPH.

FRIDAY: Sun and passing clouds. Highs 68-75. DP ~ 50. Wind NW 5-15 MPH.

FRIDAY NIGHT: Increasing clouds. Lows 53-60. DP ~ 50. Wind N 5-15 MPH.

SATURDAY: Lots of clouds / some sun. Highs 66-73. DP lower 50s. Wind N 5-15 MPH except 15-25 MPH Cape Cod with higher gusts possible.

DAYS 6-10 (SEPTEMBER 17-21)

A fair weather end to the weekend on September 17. Next trough brings a chance of wet weather early next week but is expected to be progressive, with a drying trend into and through the midweek period. Temperatures somewhat variable, but not that far from normal.

DAYS 11-15 (SEPTEMBER 22-26)

Looking for a generally zonal flow pattern, a little warmer than average but a cooler interlude or two. A little more confident we’ve lost the wet pattern at this point and are in a fairly quiet one.

DAYS 1-5 (SEPTEMBER 11-15)

Three unsettled days, a transition day, and a nice day with low humidity will be how this 5-day period unfolds. First, a nearly stationary front sits over the region today, like much of the weekend. Plenty of low level moisture has the region under lots of low clouds with areas of fog to start the day, but some of that will break and try to clear out, only to have clouds above that be dominant in association with the frontal boundary and a little wave of low pressure moving along it. This will trigger additional shower activity today, and it may become rather widespread by later in the day too, into part of the evening, before exiting. Overnight, we lose the rain chance, but gain the fog back, and it may be quite dense in some locations as well, persisting into Tuesday morning before it thins out again and dissipates. During the day Tuesday, a little very weak high pressure bubble pushes the frontal boundary in the region offshore, and allows clouds to break for some partial sun, but any sun will help a few showers pop up during the afternoon – this time favoring interior southern NH and central MA. Any of those dissipate by evening and just some clouds/fog will be around at night. The clouds hang on through Wednesday as another front approaches from the west, bringing showers and thunderstorms to the region especially Wednesday afternoon and night, lingering into the early part of Thursday. Finally, this front, which will be moving along much more swiftly, will push offshore allowing a transition to drier air during the day on Thursday, and a really nice mid September day on Friday with fair weather and low humidity.

TODAY: Mostly cloudy. Showers likely, especially in the afternoon. Chance of thunderstorms. Areas of fog early. Highs 71-78. DP near 70. Wind S to variable up to 10 MPH.

TONIGHT: Cloudy. Areas of fog, possibly dense. Showers end in the evening. Lows 62-69. DP 60s. Wind variable up to 10 MPH.

TUESDAY: Early morning foggy areas, otherwise clouds break for partial sun. Isolated afternoon showers favoring central MA / southwestern NH. Highs 73-80, warmest well inland. Wind variable up to 10 MPH with light coastal sea breezes.

TUESDAY NIGHT: Mostly cloudy. Lows 61-68. DP near 60. Wind SE under 10 MPH.

WEDNESDAY: Mostly cloudy. Showers likely and a chance of thunderstorms midday on. Highs 71-78. DP 60s. Wind S 5-15 MPH.

WEDNESDAY NIGHT: Cloudy. Showers continue. Areas of fog. Lows 61-68. DP 60+. Wind SW up to 10 MPH.

THURSDAY: Cloudy early with showers ending from west to east, then a sun/cloud mix. Highs 70-77. DP falling 60s to 50s. Wind W 5-15 MPH.

THURSDAY NIGHT: Clearing. Lows 55-62. DP near 50. Wind WNW 5-15 MPH.

FRIDAY: Sun and passing clouds. Highs 68-75. DP ~ 50. Wind NW 5-15 MPH.

DAYS 6-10 (SEPTEMBER 16-20)

Hurricane Lee’s closest pass, likely well offshore, will be taking place early in the period, during the September 16-17 weekend. While some guidance has given the track of Lee a little wiggle to the west, I’m not ready to buy that, as we’ve seen that before only to have guidance correct itself later. I’m aware that this has shown up on 3 major medium range models, but my feeling is the same at this point. Monitoring ensembles and trends is still the way to go early this week. Our weekend will be mostly fair with breezy conditions and fairly low humidity as Lee passes by to the east, but it will most certainly result in another round of rough surf along the coastline. Early-mid next week, another trough moves in from the west and a chance of showers – timing to be fine-tuned – but doesn’t look as wet as the current episode.

DAYS 11-15 (SEPTEMBER 21-25)

As we close out summer and welcome autumn, a zonal pattern should give us more dry weather than unsettled, lower humidity, and variable but mostly near normal temperatures as we head into late month.

DAYS 1-5 (SEPTEMBER 10-14)

A few adjustments are being made on this 5-day forecast update, but nothing major. The changes are that I am a little less optimistic about a nicer day Tuesday, but more optimistic about a nicer Thursday. We stay in the humid and unsettled pattern as one trough moves through the region today into Monday. With a lack of a good push of drier air we can’t clear out efficiently on Tuesday between that trough and its follow-up from the west, which brings more unsettled weather to our region into midweek. However it does look progressive enough to get east of our region and finally allow some much drier air from Canada to arrive via the Great Lakes Thursday.

TODAY: Mostly cloudy. Occasional showers and thunderstorms likely, favoring the I-95 belt westward. Highs 78-85. DP near 70. Wind S 5-15 MPH.

TONIGHT: Mostly cloudy. Areas of fog. Scattered showers and a possible thunderstorm. Lows 65-72. DP 60s. Wind S up to 10 MPH.

MONDAY: Mostly cloudy. Showers likely, especially in the afternoon. Chance of thunderstorms. Areas of fog early. Highs 73-80. DP near 70. Wind S to variable up to 10 MPH.

MONDAY NIGHT: Showers/storms end, clouds remain, patchy fog forms. Lows 60-67. DP 60s. Wind variable to E up to 10 MPH.

TUESDAY: Mostly cloudy. A shower or patch of coastal drizzle possible. Highs 70-77. DP 60s. Wind E up to 10 MPH.

TUESDAY NIGHT: Mostly cloudy. Lows 61-68. DP near 60. Wind SE under 10 MPH.

WEDNESDAY: Mostly cloudy. Afternoon showers likely. Highs 71-78. DP 60s. Wind S 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Showers ending. Areas of fog. Lows 58-65. DP near 60. Wind SW up to 10 MPH.

THURSDAY: Sun/cloud mix. Highs 70-77. DP falling through 50s. Wind W 5-15 MPH.

DAYS 6-10 (SEPTEMBER 15-19)

Hurricane Lee’s closest pass, well offshore, will be taking place early to mid period, stirring up big waves along the coast, otherwise we see dry weather here through the middle weekend of the month with pleasant late summer conditions. The next unsettled weather chance comes from a trough moving in from the west later in the period.

DAYS 11-15 (SEPTEMBER 20-24)

Drier trend with more northwesterly flow expected, along with more seasonable temperatures.

DAYS 1-5 (SEPTEMBER 9-13)

Yesterday, a complex of thunderstorms came out of CT and northeastward across a swath of east central to northeastern MA into southeastern NH. Along this path there were numerous incidences of straight-line or downburst wind damage (no tornadoes). That batch of storms was a surprise to me, as I wasn’t really expecting anything to develop ahead of the showers/storms that made a run at us from the west later in the evening. Those at least behaved about as expected after the surprise event earlier. Now, we have a stretch of unsettled weather on our hands. The September heat is for the most part gone, but the humidity will hang around for a few more days as a trough of low pressure swings through from west to east. But it’s going to take until early Tuesday to get through the region, so we have a lot of cloudiness in the forecast. Showers and thunderstorms will be around, though I think thunder-production out of these will become more the exception than the rule and we should not be seeing a repeat of damaging storms that some areas saw yesterday. I suspect that the activity will be only isolated to scattered today, scattered to numerous at times on Sunday, and after starting out just scattered may become more widespread on Monday, which regionwide should end up being the wettest of the next three days. We get a break on Tuesday as a little bubble of high pressure brings slightly drier air and reduces the shower chance to nil or just isolated pop-ups. Wednesday, another trough moves in from the west with a better chance of showers once again.

TODAY: Clouds dominate. Intervals of sun. Isolated to scattered showers and possible thunderstorms, favoring the second half of the afternoon. Highs 79-86, coolest South Coast. DP ~ 70. Wind S up to 10 MPH.

TONIGHT: Mostly cloudy. Patchy fog. A shower possible. Lows 63-70. DP 60s. Wind S under 10 MPH.

SUNDAY: Mostly cloudy. Occasional showers and thunderstorms likely, favoring the I-95 belt westward. Highs 78-85. DP near 70. Wind S 5-15 MPH.

SUNDAY NIGHT: Mostly cloudy. Areas of fog. Scattered showers and a possible thunderstorm. Lows 65-72. DP 60s. Wind S up to 10 MPH.

MONDAY: Mostly cloudy. Showers likely, especially in the afternoon. Chance of thunderstorms. Areas of fog early. Highs 73-80. DP near 70. Wind S to variable up to 10 MPH.

MONDAY NIGHT: Showers/storms end, clouds remain, patchy fog forms. Lows 60-67. DP 60s. Wind variable to W up to 10 MPH.

TUESDAY: Cloud/sun mix. An isolated pop up shower may occur over inland hills. Highs 70-77. DP near 60. Wind W 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 61-68. DP near 60. Wind SW under 10 MPH.

WEDNESDAY: Mostly cloudy. Afternoon showers likely. Highs 71-78. DP 60s. Wind S 5-15 MPH.

DAYS 6-10 (SEPTEMBER 14-18)

Our unsettled weather will continue early in the period due to a trough moving through from west to east. Hurricane Lee will be making its closest pass but still likely well offshore around September 15-16 based on current timing – keeping in mind this timing is not nailed down quite yet. This storm would send larger waves to the coast again as we’ve seen from several systems out there recently. An interlude of drier weather after the initial unsettled weather, and then another system may bring showers to our region from the west later in the period.

DAYS 11-15 (SEPTEMBER 19-23)

Drier trend with more northwesterly flow expected, along with more seasonable temperatures.

DAYS 1-5 (SEPTEMBER 8-12)

The September hot spell peaked yesterday with many areas cracking 90, including Boston’s Logan Airport, adding their 5th 90+ day to the short list this summer (there have been several more in general over inland areas). But now we’re going to turn the heat down over the next few days, but keep the humidity high, as a low pressure trough moves in from the west, slowly, and an accompanying frontal system approaches. This will increase the shower and thunderstorm chances as we head into and through the weekend, probably peaking on Monday as the actual front moves through. Yup, it’s a slow process as things are not moving along swiftly in the regional atmosphere right now. Last evening, some showers and storms made it into the far western / northwestern reaches of the WHW forecast area as was expected to be at least possible. As we go through the next few days, this area expands eastward ever-so-slowly, with today’s activity later on still expected to be mostly north of I-90 but west of I-495. The I-495 belt is more included in Saturday’s threat while I-95 eastward may remain free of the threat. But Sunday, include more of the region including the I-95 belt, while southeastern MA escapes the chance, at least for a part of the day, and then I believe it’s a regionwide threat with highest coverage on Monday. Finally, a break should come Tuesday as the front/trough pull to the east. While we’re not going to dive back into any autumn-like coolness during the next 5 days, when we get to Tuesday we’ll at least lose some of the humidity.

TODAY: Partial sun. A late-day shower or t-storm may visit central MA or southwestern NH. Highs 83-90. Dew point hovering around 70. Wind S 5-15 MPH.

TONIGHT: Variably cloudy. A shower or thunderstorm potential in the evening, especially north and west of Boston. Areas of fog. Lows 64-71. Dew point similar. Wind S up to 10 MPH.

SATURDAY: Partly sunny. A passing shower or thunderstorm possible in the afternoon mainly eastern CT, central and northeastern MA, southwestern and south central NH. Highs 81-88. Dew point near 70. Wind S 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Patchy fog. Lows 63-70. Dew point 60s. Wind SW-S up to 10 MPH.

SUNDAY: Variably cloudy. Occasional showers and thunderstorms likely, favoring the I-95 belt westward. Highs 78-85. Dew point 60s. Wind S 5-15 MPH.

SUNDAY NIGHT: Mostly cloudy. Areas of fog. Scattered showers and a possible thunderstorm. Lows 65-72. Dew point 60s. Wind S up to 10 MPH.

MONDAY: Mostly cloudy. Showers likely. Chance of thunderstorms. Areas of fog early. Highs 73-80. Dew point near 70. Wind S to variable up to 10 MPH.

MONDAY NIGHT: Showers/storms end, clouds remain, patchy fog forms. Lows 60-67. Dew point 60s. Wind variable to W up to 10 MPH.

TUESDAY: Clouds break for sun. Highs 70-77. Dew point near 60. Wind W 5-15 MPH.

DAYS 6-10 (SEPTEMBER 13-17)

Three things to watch. 1) Hurricane Lee in the western Atlantic basin, with best odds favoring an offshore track between Bermuda and the US East Coast, closest pass to New England around mid period with primary impact being rough surf / large swells. Note: Lee should weaken a little more quickly than climatology would indicate due to a lingering wake cool pool from recent Hurricane Franklin, but it will still likely be quite powerful as it tracks through that area. 2) Trough of low pressure from the west, instrumental in helping keep Lee to the east of the US Mainland. But this system will likely bring high humidity and showery weather to our region during the first half of this period. 3) The exit of the trough allowing a cooler/dry air mass to visit from Canada later in the period.

DAYS 11-15 (SEPTEMBER 18-22)

As we head through the final 5 full days of summer just prior to the autumnal equinox, the strongest indications are for a drier pattern with high pressure being more dominant, keeping most unsettled weather to the south and/or west of our region.

DAYS 1-5 (SEPTEMBER 7-11)

A couple more days of summer heat and several more days of high humidity are on our weather menu as we head from midweek through the second weekend of September, and it’s still very much summertime, so if decided to carve your pumpkin weeks in advance, keep in mind it probably won’t last that long, while you sip your pumpkin spice iced coffee to wash down that piece of Halloween candy you sneaked because it’s going to melt in the heat anyway, and tweak your Halloween decorations. The weather will be staying in-season for a while longer. The high pressure ridge that brought us the hotter weather will slide to the east today and park offshore Friday into the weekend. Initially it is going to hold back the shower and thunderstorm threat from an approaching trough to our west, but with time, it will make its way in here. The chances are very minimal that something rogue survives into the western reaches of the WHW forecast area this evening, and again tomorrow afternoon or evening, with similar on Saturday – maybe just a slight up-tick in the chances that day too. But it’s really more of a Sunday-Monday time frame when a frontal boundary finally cuts its way across the region with a better wet weather opportunity. Heat peaks today, but again some coastal areas may be delayed due to a sea breeze. If Boston breaks 90 for the 5th time this year, it happens late today when the sea breeze quits. I don’t think they have a shot at it tomorrow and nobody will be reaching 90 or higher as we move into and through the weekend, as despite the high humidity remaining, a slow cooling trend will be just getting underway.

TODAY: Lots of sun. Highs 87-94, coolest coast. Dew point 65-72. Wind variable up to 10 MPH with coastal sea breezes, then SW 5-15 MPH later.

TONIGHT: Partly cloudy. Slight chance of a stray shower or t-storm southwestern NH or central MA early. Areas of fog form. Lows 65-72. Dew point similar. Wind SW up to 10 MPH.

FRIDAY: Partial sun. A late-day shower or t-storm may visit central MA or southwestern NH. Highs 83-90. Dew point hovering around 70. Wind S 5-15 MPH.

FRIDAY NIGHT: Variably cloudy. A shower or thunderstorm potential in the evening, especially north and west of Boston. Areas of fog. Lows 64-71. Dew point similar. Wind S up to 10 MPH.

SATURDAY: Partly sunny. A passing shower possible in the afternoon mainly eastern CT, central MA, southwestern NH. Highs 81-88. Dew point near 70. Wind S 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Patchy fog. Lows 63-70. Dew point 60s. Wind SW-S up to 10 MPH.

SUNDAY: Variably cloudy. Chance of showers and thunderstorms. Highs 78-85. Dew point 60s. Wind S 5-15 MPH.

SUNDAY NIGHT: Mostly cloudy. Areas of fog. Scattered showers and a possible thunderstorm. Lows 65-72. Dew point 60s. Wind S up to 10 MPH.

MONDAY: Mostly cloudy. Showers likely. Chance of thunderstorms. Areas of fog early. Highs 73-80. Dew point near 70. Wind S to variable up to 10 MPH.

DAYS 6-10 (SEPTEMBER 12-16)

Briefly fair and less humid early in the period then the approach of another trough from the west by the middle of next week brings another spike in humidity and increased shower chances. At the same time we’ll be watching offshore Hurricane Lee, which, while still being too far out in time to nail down any specifics, has a fairly strong chance of passing well offshore of the Northeast late in this forecast period. Outer effects (high swells / heavy surf / an outer rain band reaching eastern areas) are all potentials when you look out at a passing system this far in advance. Tracking/tweaking will be ongoing at the proper pace, and here I put a caution for you to know your information sources regarding weather. Use trusted ones, with meteorologists giving the info. Use social media with extreme caution.

DAYS 11-15 (SEPTEMBER 17-21)

Overall pattern looks cooler / drier with more northwesterly flow from Canada. More specifics to come.

DAYS 1-5 (SEPTEMBER 6-10)

A September hot spell lasts a few more days before it eases up on us. We haven’t had much in the way of heat to deal with all summer so getting a spike if it now will make those not used to it feel it that much more. The good news about getting hotter weather at this time of year, if you don’t care for it, is that with shorter daylight and lower sun angle it takes away from some of the intensity, especially since there is going to be fairly high humidity to go along with that heat. Its origin is that long-standing hot spell in the middle of the country as an adjustment in the pattern allows the ridge to slide eastward across our region over the next few days. Once the ridge axis gets offshore late in the week, we’ll watch for the approach of a trough from the west and an increase in shower and thunderstorm chances, but this may be quite slow to occur, keeping our weather mainly rain-free into the weekend. We’ll have to watch for remnant showers and storms approaching the WHW forecast area from the west Thursday evening and again some favoring the western portion of the area Friday and Saturday, with Sunday seeing an increase in chance and coverage.

TODAY: Mostly sunny to partly cloudy. Highs 84-91. Dew point 60s. Wind SW 5-15 MPH.

TONIGHT: Partly cloudy. Patchy fog in lower elevations. Lows 63-70. Dew point 60s. Wind SW up to 10 MPH.

THURSDAY: Partly sunny. Highs 86-93. Dew point 60s. Wind SW 5-15 MPH.

THURSDAY NIGHT: Variably cloudy. Chance of a shower or thunderstorm. Areas of fog. Lows 63-70. Dew point 60s. Wind SW up to 10 MPH.

FRIDAY: Partly sunny. Chance of a late-day shower and thunderstorm favoring western areas. Highs 84-91. Dew point 60s. Wind SW 5-15 MPH.

FRIDAY NIGHT: Variably cloudy. Chance of a shower or thunderstorm. Areas of fog. Lows 64-71. Dew point 60s. Wind SW up to 10 MPH.

SATURDAY: Partly sunny. A few showers/thunderstorms possible mainly in the afternoon and mainly in western portions of the region. Highs 82-89. Dew point 60s. Wind SW 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Patchy fog. Lows 63-70. Dew point 60s. Wind SW-S up to 10 MPH.

SUNDAY: Variably cloudy. Chance of showers and thunderstorms. Highs 78-85. Dew point 60s. Wind S 5-15 MPH.

DAYS 6-10 (SEPTEMBER 11-15)

Frontal boundary still in the vicinity with high humidity and wet weather chances to start the period, and another mid period frontal boundary may bring a shower or thunderstorm chance. Not as warm as previously, but temperatures still somewhat above normal into mid month. By late period we may be seeing a strong tropical system (Hurricane Lee) somewhere off the US East Coast. While it being far too soon to know the specific track, the early indications from the most reliable guidance indicate a track far enough offshore to spare the East Coast (and our region) any direct impact. Obviously, it’s in need of watching as time goes on.

DAYS 11-15 (SEPTEMBER 16-20)

Any offshore tropical system exits the vicinity (if it’s in the vicinity) early in the period, and the general pattern switches up to allow a shot or 2 of cooler/drier air from Canada, with the potential for showers during air mass changes. More details to come.

DAYS 1-5 (SEPTEMBER 5-9)

It’s late summer and after a long meteorological summer of unsettled weather, we have a long stretch of fair, summertime weather in progress. This continues into late week too as a ridge of high pressure at upper levels centered to our west drifts to the east, crossing the region by Thursday and sliding offshore by Friday. Some interior sections make a run at a heatwave (3 days with high temps of 90 or higher). Although this won’t qualify as intense heat, it’ll feel pretty hot with the higher humidity coming in. An approaching trough will trigger thunderstorms to our west later Thursday and at least the remnant cloudiness will make it here later that day, and maybe a stray lingering shower or storm at night, with something similar by later Friday too, but largely it’s a fair weather stretch through Friday, and maybe even for at least part of the area Saturday with the ridge, which will then be to our east, being strong enough to hold activity from an approaching frontal boundary back mostly in western portions of our region. Fine-tuning will be required for that part of the forecast as we get closer to the weekend.

TODAY: Mostly sunny. Highs 83-90. Dew point middle to upper 60s. Wind SW 5-15 MPH.

TONIGHT: Mostly clear. Fog patches in lowest elevations. Lows 63-70. Dew point 60s. Wind SW up to 10 MPH.

WEDNESDAY: Mostly sunny to partly cloudy. Highs 84-91. Dew point 60s. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Patchy fog in lower elevations. Lows 63-70. Dew point 60s. Wind SW up to 10 MPH.

THURSDAY: Partly sunny. Highs 86-93. Dew point 60s. Wind SW 5-15 MPH.

THURSDAY NIGHT: Variably cloudy. Chance of a shower or thunderstorm. Areas of fog. Lows 63-70. Dew point 60s. Wind SW up to 10 MPH.

FRIDAY: Partly sunny. Chance of a late-day shower and thunderstorm favoring western areas. Highs 84-91. Dew point 60s. Wind SW 5-15 MPH.

FRIDAY NIGHT: Variably cloudy. Chance of a shower or thunderstorm. Areas of fog. Lows 64-71. Dew point 60s. Wind SW up to 10 MPH.

SATURDAY: Partly sunny. A few showers/thunderstorms possible mainlyin the afternoon and mainly in western portions of the region. Highs 82-89. Dew point 60s. Wind SW 5-15 MPH.

DAYS 6-10 (SEPTEMBER 10-14)

Current idea is that high pressure sits offshore long enough to slow a frontal boundary down so it doesn’t completely cross the region until later September 11, leaving the region vulnerable to showers/thunderstorms with fairly high humidity until then. Fair weather follows for the middle of next week with temperatures not as warm, but still near to above normal.

DAYS 11-15 (SEPTEMBER 15-19)

A tropical system will possibly be passing east of our region offshore around the start of this period which may at least rough-up the coastal waters but the very early idea is that a direct impact is highly unlikely. Otherwise a mostly fair weather pattern is expected with near to above normal temperatures.

DAYS 1-5 (SEPTEMBER 4-8)

It’s still the weekend for many people on this Labor Day 2023, and it will have the feel of summer with high pressure sitting just to the south and east, pumping in very warm and more humid air. This pattern will hold into midweek too as the high doesn’t move much. Coastal areas will end up a little cooler probably all of the next 3 days due to developing sea breezes. A frontal boundary will move toward the region later Thursday into Friday when the shower and thunderstorm chance will increase…

TODAY (LABOR DAY): Mostly sunny. Highs 81-88, falling back to 70s coast. Dew point60+. Wind SW up to 10 MPH with coastal sea breezes developing.

TONIGHT: Mostly clear. Fog patches in lowest elevations. Lows 62-69. Dew point lower to middle 60s. Wind SW under 10 MPH.

TUESDAY: Mostly sunny. Highs 82-89. Dew point middle to upper 60s. Wind SW 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Fog patches in lowest elevations. Lows 63-70. Dew point 60s. Wind SW up to 10 MPH.

WEDNESDAY: Mostly sunny to partly cloudy. Highs 83-90. Dew point 60s. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Patchy fog in lower elevations. Lows 63-70. Dew point 60s. Wind SW up to 10 MPH.

THURSDAY: Partly sunny. Chance of showers/thunderstorms late-day or night. Highs 80-87. Dew point 60s. Wind SW 5-15 MPH.

THURSDAY NIGHT: Variably cloudy. Chance of a shower or thunderstorm. Areas of fog. Lows 63-70. Dew point 60s. Wind SW up to 10 MPH.

FRIDAY: Variably cloudy. Chance of showers and thunderstorms. Highs 78-85. Dew point 60s to 70. Wind SW to variable 5-15 MPH.

DAYS 6-10 (SEPTEMBER 9-13)

The trends have been to slow the frontal boundary down with high pressure offshore and no big push from the west. This means higher humidity and shower/thunderstorm chances can linger during the September 9-10 weekend, maybe even into early the following week. Eventually a push of more settled weather should arrive. Temperatures near to above normal.

DAYS 11-15 (SEPTEMBER 14-18)

Leaning toward high pressure to be the dominant feature with mostly fair weather and near to above normal temperatures during the middle of the month, but we may need to keep an eye on a potential tropical system offshore (or approaching the coast) sometime during this period as well.

DAYS 1-5 (SEPTEMBER 3-7)

A quick mid-holiday-weekend update for you today. Some sneaky showers made it into parts of the region overnight, you know, the ones that I removed from the forecast. Well, at least they didn’t interrupt any big plans, unless you were having an overnight block party where they were occurring. Anyway, they’re gone, and just some clouds linger as the triggering disturbance exits the coast. This opens the door for high pressure to re-take the field and be the only player for the next several days – the rest of the holiday weekend and beyond, into the middle of next week, along with the arrival of summertime heat and eventually higher humidity too. An approaching trough and frontal system increases at least the cloud cover and potentially the shower / t-storm chances by later Thursday…

TODAY: Early clouds, then sun dominates. Highs 78-85, coolest at the coast. Wind W up to 10 MPH with developing coastal sea breezes.

TONIGHT: Clear. Fog patches in lowest elevations. Lows 60-67. Dew point lower 60s. Wind SW under 10 MPH.

MONDAY (LABOR DAY): Mostly sunny. Highs 81-88, turning cooler in some coastal areas during the afternoon. Dew point middle 60s. Wind SW up to 10 MPH with some coastal sea breezes redeveloping.

MONDAY NIGHT: Mostly clear. Fog patches in lowest elevations. Lows 62-69. Dew point lower to middle 60s. Wind SW under 10 MPH.

TUESDAY: Mostly sunny. Highs 82-89. Dew point middle to upper 60s. Wind SW 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Fog patches in lowest elevations. Lows 63-70. Dew point 60s. Wind SW up to 10 MPH.

WEDNESDAY: Mostly sunny to partly cloudy. Highs 83-90. Dew point 60s. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Patchy fog in lower elevations. Lows 63-70. Dew point 60s. Wind SW up to 10 MPH.

THURSDAY: Partly sunny. Chance of showers/thunderstorms late-day or night. Highs 80-87. Dew point 60s. Wind SW 5-15 MPH.

DAYS 6-10 (SEPTEMBER 8-12)

A trough moves through the region from west to east late this week – slowly – bringing humid weather and a shower/thunderstorm chance to start. Expecting a frontal boundary to move offshore early in the weekend but higher humidity and at least a slight shower chance may linger at first before we trend drier late weekend and beyond. Temperatures should run slightly above normal overall for this period.

DAYS 11-15 (SEPTEMBER 13-17)

Still leaning toward high pressure to be more dominant than low pressure which is pushed more to the south, so the idea continues to be a mild / dry pattern with a cooler shot of air from Canada possible at some point too.

DAYS 1-5 (SEPTEMBER 2-6)

This Labor Day Weekend definitely completes the book-end fair-weather holiday weekends for the summer tourist / vacation season as high pressure, sitting just to our south, governs the weather and provides rain-free conditions. A high-altitude wildfire smoke plume from western Canada provides a hazy look to the sky today but as it moves out later in the day the sky will lose the hazy look. A disturbance will pass by the region tonight with some cloudiness, but its timing takes it out of the region by morning, leaving Sunday with lots of sun and warmer than today. Labor Day Monday into the middle of next week will feature rain-free weather with very warm and more humid weather – the feel of summer just at its unofficial ending.

TODAY: Smoke-filtered sun becomes brighter with time then becomes interrupted by high clouds at times later in the day. Highs 72-79. Dew point middle 50s. Wind W up to 10 MPH.

TONIGHT: Lots of clouds. Lows 57-64. Dew point middle 50s. Wind SW under 10 MPH.

SUNDAY: Mostly sunny. Highs 78-85. Dew point near 60. Wind SW up to 10 MPH.

SUNDAY NIGHT: Mostly clear. Fog patches in lowest elevations. Lows 60-67. Dew point lower 60s. Wind SW under 10 MPH.

MONDAY (LABOR DAY): Mostly sunny. Highs 81-88. Dew point middle 60s. Wind SW up to 10 MPH.

MONDAY NIGHT: Mostly clear. Fog patches in lowest elevations. Lows 62-69. Dew point lower to middle 60s. Wind SW under 10 MPH.

TUESDAY: Mostly sunny. Highs 82-89. Dew point middle to upper 60s. Wind SW 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Fog patches in lowest elevations. Lows 63-70. Dew point 60s. Wind SW up to 10 MPH.

WEDNESDAY: Mostly sunny. Highs 83-90. Dew point 60s. Wind SW 5-15 MPH.

DAYS 6-10 (SEPTEMBER 7-11)

Still expecting the arrival of unsettled weather by the start of this period with high humidity and showers/thunderstorms. How long does it hang around is the question. May remain unsettled until mid period before we dry out again as things slow down a bit in the atmosphere. Will monitor and fine-tune. Temperatures come back down to more seasonable levels.

DAYS 11-15 (SEPTEMBER 12-16)

Leaning toward high pressure to be more dominant than low pressure which is pushed more to the south, so the idea here is mild and mainly dry, but not said with high confidence.

DAYS 1-5 (SEPTEMBER 1-5)

Welcome to meteorological autumn, which is going to start out with what’s considered the last weekend of summer by “tourism” standards and still 3 weeks away from the actual (astrononimcal) end of summer / start of autumn. We’re a confusing lot, aren’t we? Well, at least this first morning of meteorological autumn has a bit of a fall feel, with chilly and dry air in place. And the day itself will be on the cooler side of normal, but sunny as high pressure floats across the region. And then as we get into the first few days of the new meteorological season, the actual astronomical season reminds us that it’s still alive and well, despite the pattern of much of it, by delivering us a warming trend and a long stretch of fair weather through the holiday weekend and even beyond. This will take place as high pressure sits offshore to the south and southeast of our region. The only “interruption” if you will is going to come in the form of an old frontal boundary and upper level disturbance that cross the region between Saturday night and later Sunday, bringing some clouds. You’ll also notice a hazier look to the sky later today into Saturday as a plume of high altitude wildfire smoke moves across the region from Canada. As far as the front and disturbance go, I still feel that the chance of any rain shower activity is so minimal that it’s not even worth putting in the forecast at this point. As we go through the days, it gets a little warmer each of them, with a slow increase in humidity not really noticeable to later Sunday or Monday and most especially Tuesday… Additionally, some rough surf and remaining rip current risk along the coast will diminish as we head into the holiday weekend – good news for those with plans that involve the coastline and/or coastal waters.

TODAY: Sunshine, becoming filtered later in the day by high altitude smoke. Highs 70-77. Dew point middle 40s to lower 50s. Wind N up to 10 MPH becoming variable with light coastal sea breezes developing.

TONIGHT: Clear except high altitude smoke. Fog patches in lowest elevations. Lows 52-59. Dewpoint lower 50s. Wind calm.

SATURDAY: Sunny to partly cloudy. High altitude smoke, diminishing late. Highs 72-79. Dew point middle 50s. Wind WSW up to 10 MPH.

SATURDAY NIGHT: Variably cloudy. Fog patches in lowest elevations. Lows 56-63. Dew point middle 50s. Wind SW under 10 MPH.

SUNDAY: Partly to mostly sunny. Highs 77-84. Dew point near 60. Wind SW up to 10 MPH.

SUNDAY NIGHT: Mostly clear. Fog patches in lowest elevations. Lows 60-67. Dew point lower 60s. Wind SW under 10 MPH.

MONDAY (LABOR DAY): Mostly sunny. Highs 81-88. Dew point middle 60s. Wind SW up to 10 MPH.

MONDAY NIGHT: Mostly clear. Fog patches in lowest elevations. Lows 62-69. Dew point lower to middle 60s. Wind SW under 10 MPH.

TUESDAY: Mostly sunny. Highs 82-89. Dew point middle to upper 60s. Wind SW 5-15 MPH.

DAYS 6-10 (SEPTEMBER 6-10)

High pressure remains offshore through midweek with warm, humid conditions here. Fair weather will be followed by an increased chance of showers as a trough and frontal system approach and move in from the west. A little uncertain still as to how long this hangs around as another high pressure area to the west will try to push in to dry the region out later in the period, as well as bringing less humid and somewhat cooler air. Fine-tuning to be done.

DAYS 11-15 (SEPTEMBER 11-15)

A little hint of high pressure west and north, low pressure to south, in the general upper pattern. Overall pattern here is most likely mild and somewhat unsettled heading into the middle of the month.
