DAYS 1-5 (AUGUST 29 – SEPTEMBER 2)

As we head into the final weekend of August, there is a little update on the outlook – not a huge change, but the timing of the next disturbance is faster, so that clouds and a passing shower chance come back during Sunday afternoon and evening. Otherwise, it’s a fairly dry weekend with high pressure in control today and early Sunday before it slips offshore to make way from the disturbance from the west northwest. This system goes by quickly enough so that Monday, the final day of August, looks quite nice. September opens with a bout of unsettled weather from a pair of disturbances traveling through our region in a west northwest flow Tuesday and Wednesday. Episodic showers are likely, but the exact timing / details are to-be-determined as we get a little closer to those days.

TODAY: Partly cloudy this morning. Mostly sunny this afternoon. Highs 75-82. Dew point in 50s. Wind W to variable up to 10 MPH.

TONIGHT: Mostly clear. Ground fog patches. Lows 56-63. Dew point in 50s. Wind W under 10 MPH.

SUNDAY: Sunshine most prominent morning, then variably cloudy with a passing shower possible afternoon. Highs 77-84. Dew point sub-60. Wind variable up to 10 MPH with coastal sea breezes then S up to 10 MPH late-day.

SUNDAY NIGHT: Partly cloudy. A shower chance early. Patchy fog late. Lows 58-65. Dew point sub-60. Wind SW up to 10 MPH.

MONDAY: Mostly sunny. Highs 76-83, coolest eastern coastal areas. Dew point sub-60. Wind W shifting to NE 5-15 MPH.

MONDAY NIGHT: Increasing clouds. Fog patches. Lows 56-63. Wind SE up to 10 MPH.

TUESDAY: Mostly cloudy. Showers likely. Highs 66-73. Wind SE up to 10 MPH.

TUESDAY NIGHT: Mostly cloudy. Areas of fog. Chance of a shower. Lows 58-65. Wind variable up to 10 MPH.

WEDNESDAY: Variably cloudy. Chance of showers. Highs 67-74. Wind variable 5-15 MPH.

DAYS 6-10 (SEPTEMBER 3-7)

Trending fair early to mid period before unsettled weather chances return toward the end of the period. Temperatures near to above normal.

DAYS 11-15 (SEPTEMBER 8-12)

Fair weather early and late period with unsettled weather between that at mid period. Temperatures somewhat variable but fairly close to normal overall.

DAYS 1-5 (AUGUST 28 – SEPTEMBER 1)

Last night I had a dream that I was helping somebody move today (and it was Saturday, and raining, and I had forecast a sunny day, and I remember leaning against the wall and saying “well, this is my worst forecast…like ever”) and then I woke up and it was cloudier than I forecast, but at least I did (and do) expect more cloudiness today than yesterday. I guess it could be worse! We have some stratus in the region now, and while that will largely dissipate and morph into passing fractocumulus and some larger cumulus later, we will also have a considerable amount of mid and high level clouds streaming up from the southwest today. All of this together means sunshine will be limited today. And with a front crossing the region add in the chance of a few showers and thunderstorms in the region during this afternoon. The front clears the region tonight and sets us up for a spectacular weekend as high pressure builds in Saturday, then slips offshore Sunday. I now expect a second area of high pressure in eastern Canada to push a back-door cold front down via the Gulf of Maine on Monday, but this should be with little fanfare, other than a wind shift and cooler air along the eastern coastal areas in comparison to the weekend. So we big farewell to August with a fairly nice weather pattern during the next several days overall. September opens with unsettled weather as a trough arrives from the west with lots of clouds and some wet weather likely by Tuesday.

TODAY: Clouds limit sunshine. A shower or thunderstorm possible this afternoon. Highs 76-83. Dew point 60+. Wind SW 5-15 MPH.

TONIGHT: Lots of clouds early, then clearing. Lows 58-65. Dew point drops under 55. Wind W 5-15 MPH.

SATURDAY: Mostly sunny. Highs 75-82. Dew point in 50s. Wind W to variable up to 10 MPH.

SATURDAY NIGHT: Mostly clear. Ground fog patches. Lows 56-63. Dew point in 50s. Wind W under 10 MPH.

SUNDAY: Mostly sunny. Highs 78-85. Dew point sub-60. Wind variable up to 10 MPH with coastal sea breezes then S up to 10 MPH late-day.

SUNDAY NIGHT: Partly cloudy. Patchy fog. Lows 58-65. Dew point sub-60. Wind SW up to 10 MPH.

MONDAY: Mostly sunny. Highs 76-83, coolest eastern coastal areas. Dew point sub-60. Wind W shifting to NE 5-15 MPH.

MONDAY NIGHT: Increasing clouds. Fog patches. Lows 56-63. Wind SE up to 10 MPH.

TUESDAY: Mostly cloudy. Showers likely. Highs 66-73. Wind SE up to 10 MPH.

DAYS 6-10 (SEPTEMBER 2-6)

Unsettled weather as a trough passes by with shower chances September 2, followed by fair weather mid period, then a shower chance returns late period. Temperatures near normal.

DAYS 11-15 (SEPTEMBER 7-11)

Unsettled weather opportunities around September 7 and 10 in an otherwise mostly dry weather pattern. Temperatures somewhat variable but fairly close to normal overall.

DAYS 1-5 (AUGUST 27-31)

No significant changes to the ongoing outlook – just a little timing tweak for slightly slower / later on shower and t-storm chances for today and Friday due to the slightly slower movement of the associated disturbance, which keeps the chance mostly to the west later today and coverage fairly low through Friday. This means despite the unsettled weather chances, most of the time through Friday we’ll have rain-free conditions with varying amounts of cloudiness and fairly warm, humid later summer conditions. High pressure controls our weather with fair weather and lower humidity for this coming weekend, before the next disturbance in a northwesterly flow brings a shower and thunderstorm chance back by Monday.

TODAY: Partly sunny. Scattered showers and thunderstorms possible by late afternoon, favoring areas west of I-95. Highs 80-87. Dew point climbs into 60s. Wind SW 5-15 MPH.

TONIGHT: Variably cloudy. Scattered showers with a chance of thunderstorms. Areas of fog. Lows 62-69. Dew point 60+. Wind SW to variable up to 10 MPH

FRIDAY: Lots of clouds, patchy fog, and a shower threat early. A sun / cloud mix follows with the chance of a shower or thunderstorm in the afternoon. Highs 78-85. Dew point 60+. Wind SW to W 5-15 MPH.

FRIDAY NIGHT: Clearing. Lows 58-65. Dew point falls into 50s. Wind W 5-15 MPH.

SATURDAY: Sun and passing clouds. Highs 77-84. Dew point in 50s. Wind W 5-15 MPH.

SATURDAY NIGHT: Mostly clear. Ground fog patches. Lows 57-64. Dew point in 50s. Wind W under 10 MPH.

SUNDAY: Mostly sunny. Highs 78-85. Dew point sub-60. Wind variable up to 10 MPH with coastal sea breezes.

SUNDAY NIGHT: Partly cloudy. Patchy fog. Lows 58-65. Dew point sub-60. Wind W up to 10 MPH.

MONDAY: Partly sunny. A shower or thunderstorm chance returns. Highs 79-86. Dew point 60+. Wind SW 5-15 MPH.

DAYS 11-15 (SEPTEMBER 6-10)

Unsettled weather as the next trough passes by in the September 6-7 time frame, followed by fair weather mid to late period. Temperatures generally near normal.

DAYS 1-5 (AUGUST 26-30)

High pressure provides a “top 10” kind of summer day today with plenty of sun, manageable humidity, and fairly light wind, and while it won’t be a hot day, it won’t be nearly too cool to do stuff outside. Enjoy! (I will, it’s the first day of a 6-day weekend for me.) Some patchy clouds move through tonight marking the exit of high pressure offshore and the return of a more humid southwesterly air flow which will be noticed on Thursday. A disturbance approaching from the west can trigger a shower or thunderstorm, particularly over inland areas, late Thursday afternoon. This disturbance will then cross the region overnight to early Friday with clouds and shower chances, maybe a few thunderstorms in the mix too. A cold front still has to cross the region on Friday and can ignite a few more showers and storms, particularly in southeastern NH, eastern MA, and RI, in the midday to mid afternoon hours. This sets us up for a spectacular weekend with high pressure building in and giving us abundant sunshine, seasonable warmth, and low to moderate humidity.

TODAY: Mostly sunny. Highs 78-85. Dew point heads for 60. Wind variable to S up to 10 MPH.

TONIGHT: Partly cloudy. Fog patches. Lows 60-67. Dew point near 60. Wind SW under 10 MPH.

THURSDAY: Partly sunny. Scattered showers and thunderstorms possible mid afternoon on, favoring areas west of I-95. Highs 80-87. Dew point climbs into 60s. Wind SW 5-15 MPH.

THURSDAY NIGHT: Variably cloudy. Scattered showers with possible thunderstorms. Areas of fog. Lows 62-69. Dew point 60+. Wind SW to variable up to 10 MPH

FRIDAY: Lots of clouds, patchy fog, and a shower threat early. A sun / cloud mix follows with the chance of a shower or thunderstorm in the afternoon, favoring southeastern NH, eastern MA, and RI. Highs 78-85. Dew point 60+ but may fall later in the day. Wind SW to W 5-15 MPH.

FRIDAY NIGHT: Clearing. Lows 58-65. Dew point falls into 50s. Wind W 5-15 MPH.

SATURDAY: Sun and passing clouds. Highs 77-84. Dew point in 50s. Wind W 5-15 MPH.

SATURDAY NIGHT: Mostly clear. Ground fog patches. Lows 57-64. Dew point in 50s. Wind W under 10 MPH.

SUNDAY: Mostly sunny. Highs 78-85. Dew point sub-60. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (AUGUST 31 – SEPTEMBER 4)

Watching for a disturbance to bring a shower and t-storm chance August 31, depending on its timing. Additional showers possible September 1-2 with a trough moving through the region, followed by fair weather. Temperatures generally around normal.

DAYS 11-15 (SEPTEMBER 5-9)

Window of opportunity for showers later September 5 to September 7, then fair weather returns. Temperatures generally around to a little above normal.

DAYS 1-5 (AUGUST 25-29)

The upper low and associated cool pool of air will finish its trek across our region during today, but not before it helps initiate another round of diurnal clouds, some of which can grow enough to produce a few showers, particularly west of I-95, from mid afternoon to sunset. Otherwise, today will be quite a nice one. High pressure builds in and brings a spendid summer day Wednesday. Thursday, the high slides offshore and a southwesterly air flow brings in higher humidity, while a disturbance approaches from the west. The latter, combined with the former, increases our chance of late-day showers and thunderstorms, which then can be around at night and into early Friday as the initial disturbance passes through the region. A trailing cold front can trigger another shower or thunderstorm during the afternoon hours on Friday, which will be a warm and humid day. High pressure builds in behind this with fabulous weather to start the weekend on Saturday – lots of sun, mild air, and lower humidity.

TODAY: Abundant sun to start, then a sun / cloud mix with a shower possible west of I-95, mainly southwestern NH and central MA, from mid afternoon to sunset. Highs 75-82. Dew point under 60. Wind W 5-15 MPH.

TONIGHT: Partly cloudy. Lows 56-63. Dew point under 55. Wind W under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 78-85. Dew point heads for 60. Wind variable to S up to 10 MPH.

WEDNESDAY NIGHT: Partly cloudy. Fog patches. Lows 60-67. Dew point near 60. Wind SW under 10 MPH.

THURSDAY: Partly sunny. Scattered showers and thunderstorms possible mid afternoon on, favoring areas west of I-95. Highs 80-87. Dew point climbs into 60s. Wind SW 5-15 MPH.

THURSDAY NIGHT: Variably cloudy. Scattered showers with possible thunderstorms. Areas of fog. Lows 62-69. Dew point 60+. Wind SW to variable up to 10 MPH

FRIDAY: Lots of clouds, patchy fog, and a shower threat early. A sun / cloud mix follows with the chance of a shower or thunderstorm in the afternoon. Highs 78-85. Dew point 60+ but may fall later in the day. Wind SW to W 5-15 MPH.

FRIDAY NIGHT: Clearing. Lows 58-65. Dew point falls into 50s. Wind W 5-15 MPH.

SATURDAY: Sun and passing clouds. Highs 77-84. Dew point in 50s. Wind W 5-15 MPH.

DAYS 6-10 (AUGUST 30 – SEPTEMBER 3)

Decent summer weather to wrap up August except for a shower / t-storm chance later August 31. Shower chances increase to open up September. Temperatures near normal.

DAYS 11-15 (SEPTEMBER 4-8)

Fair weather early and late period with a shower chance between. Temperatures near normal.

DAYS 1-5 (AUGUST 24-28)

Summer “ends” several times per year these days. It’s marked by the end of meteorological summer, the end of summer vacation and return to school, Labor Day, or the actual end, referred to as the autumnal equinox. Well, the last of those is still a few weeks away, the penultimate one of my list is two weeks out, the return to school is scattered across the calendar so you can figure that one out, and the last day of meteorological summer is one week away. So for this five-day forecast, we’re still talking about summer. And we’ll have some summery weather to go along with it, although we will lack significant heat and humidity, and will still have to deal with some unsettled weather, but to a lesser degree than we did over the weekend. The frontal boundary that brought that to us is now offshore, but the upper low driving the pattern still has to cross our region, and won’t completely accomplish that journey until later Tuesday. This sets up the chance of an afternoon to early evening shower and thunderstorm chance today, and an additional opportunity for a late-day shower Tuesday, with such activity more likely west and north of Boston than anywhere else in our region. High pressure builds in to provide beautiful weather for Wednesday before it heads offshore. The next trough and front will head our way later Thursday into early Friday, bringing another shot at some shower and thunderstorm activity, though most of Thursday will be rain-free and probably the warmest day of this week (in case you happen to have beach plans, like I do!). A frontal boundary in the region can still trigger an afternoon shower or thunderstorm on Friday after the morning shower threat ends, but that day will be decent too for a good amount of its time.

TODAY: Patchy low clouds / fog to start, then plenty of sun through midday before a variably cloudy afternoon when there is the chance of scattered showers and thunderstorms, especially west of I-95. Highs 76-83. Dew point 60s coastal plain, 50s hills to west, with a slow decline during the day. Wind W 5-15 MPH.

TONIGHT: Partly cloudy. Lows 57-64. Dew point falls under 55. Wind W up to 10 MPH.

TUESDAY: Partly sunny. A shower possible west of I-95 late-day. Highs 75-82. Dew point under 60. Wind W 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 56-63. Dew point under 55. Wind W under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 78-85. Dew point heads for 60. Wind variable to S up to 10 MPH.

WEDNESDAY NIGHT: Mostly clear. Fog patches. Lows 60-67. Dew point near 60. Wind SW under 10 MPH.

THURSDAY: Sunny to partly cloudy. A late-day shower or thunderstorm possible mainly western areas. Highs 80-87. Dew point around 60. Wind SW 5-15 MPH.

THURSDAY NIGHT: Variably cloudy. Scattered showers with possible thunderstorms. Areas of fog. Lows 62-69. Dew point 60+. Wind SW to variable up to 10 MPH

FRIDAY: Lots of clouds, patchy fog, and a shower threat early. A sun / cloud mix follows with the chance of a shower or thunderstorm in the afternoon. Highs 78-85. Dew point 60+ but may fall later in the day. Wind SW to W 5-15 MPH.

DAYS 6-10 (AUGUST 29 – SEPTEMBER 2)

Decent summer weather to wrap up August except for a shower / t-storm chance sometime August 30. Shower chances increase to open up September. Temperatures near normal.

DAYS 11-15 (SEPTEMBER 3-7)

Fair weather early period. Shower chances return mid to late period. Temperatures near normal.

DAYS 1-5 (AUGUST 23-27)

Our unsettled weekend rolls on, but this is a weekend where clouds dominate much more than rainfall. Yes, there were areas of drizzle and showers yesterday while the bulk of steadier, heavier rainfall stayed offshore to our southeast. This morning, a batch of rain and embedded thunder is moving through southwestern New England as of sunrise and will slowly start to shrink as it moves northeastward into and across the WHW forecast area this morning and midday. Behind this area we see some partial clearing which can fuel the atmosphere for some isolated to scattered showers and thunderstorms later in the day. While coverage will be limited, we do have to watch for isolated occurrences of stronger to possibly severe storms before activity diminishes with the setting sun. A broad trough of low pressure, as previously mentioned, still needs to make its way across our region from west to east through Tuesday. This keeps the chance of a shower or thunderstorm in the forecast for Monday afternoon and an additional shower chance Tuesday, with activity both of those days more likely west and north of Boston. High pressure builds in with wonderful summer weather Wednesday into Thursday, but we need to watch for the potential for a shower or thunderstorm by later Thursday, at least in western areas, with the approach of our next trough / disturbance.

TODAY: Generally cloudy morning with showers and a possible thunderstorm moving southwest to northeast across the region, diminishing in coverage with time. Clouds break for partial sun this afternoon including the chance for an additional shower or thunderstorm later in the day. Highs 71-78. Dew point 60+. Wind variable up to 10 MPH becoming S.

TONIGHT: Partly to mostly cloudy. Patchy fog. A shower possible. Lows 62-69. Dew point 60+. Wind SW under 10 MPH.

MONDAY: Variably cloudy. Scattered afternoon showers and thunderstorms possible, mainly west and north of Boston. Highs 76-83. Dew point in 60s. Wind SW 5-15 MPH.

MONDAY NIGHT: Variably cloudy. Chance of a shower. Lows 61-68. Dew point near 60. Wind W up to 10 MPH.

TUESDAY: Partly sunny. Chance of a shower, mainly north and west of Boston later in the day. Highs 77-84. Dew point near to below 60. Wind W 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 60-67. Dew point falls to 50s,. Wind W 5-15 MPH.

WEDNESDAY: Mostly sunny. Highs 80-87. Dew point 50s. Wind W 5-15 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 60-67. Dew point 50s. Wind W under 10 MPH.

THURSDAY: Sunny to partly cloudy. A late-day shower or thunderstorm possible mainly western areas. Highs 81-88. Dew point around 60. Wind SW 5-15 MPH.

DAYS 6-10 (AUGUST 28 – SEPTEMBER 1)

Shower and thunderstorm chances early August 28 and around August 30 or 31, otherwise a mainly rain-free pattern. Temperatures near to above normal.

DAYS 11-15 (SEPTEMBER 2-6)

A couple disturbances may induce shower chances, but fair weather the vast majority of the time. Temperatures near to slightly above normal.

DAYS 1-5 (AUGUST 22-26)

No big changes to the ongoing outlook as we enter the weekend, which will be unsettled, but not “washed out”. A frontal boundary hosted a low pressure area which has been drifting eastward to our south since yesterday and will turn northward into the Gulf of Maine today. While looking somewhat impressive on satellite, this low is fairly weak and will remain so as it heads northeastward, keeping most of its shower activity offshore, while just some patches of drizzle occur with a light northeasterly air flow in our region, though this backs to a more northerly breeze later and may even dry it out somewhat. Tonight, another wave of low pressure heads our way up a quasi-stationary frontal boundary, bringing more widespread shower activity in the window of time that is the first 12 hours of Sunday, from south to north. This is followed by some partial clearing including some intervals of sunshine Sunday afternoon. This results in a somewhat warmer day than today, and also serves to destabilize the atmosphere to add a chance of afternoon and evening showers and thunderstorms to the mix as a disturbance moves into the region from the west. We’ll keep an eye on the potential for a few strong to severe storms occurring, however I don’t expect severe weather to be widespread. Monday and Tuesday will find an upper trough still passing across our region from west to east, so I cannot rule out a few showers and thunderstorms, especially Monday, with less of a chance on Tuesday. High pressure builds in with nice weather Wednesday.

TODAY: Mostly cloudy. Drizzle patches near the coast through midday. Slight chance of a shower, favoring southeastern MA. Highs 68-75. Dew point near 60. Wind NE to N 5-15 MPH.

TONIGHT: Mostly cloudy. Fog patches. Showers likely overnight. Lows 60-67. Dew point near 60. Wind variable up to 10 MPH.

SUNDAY: Mostly cloudy with showers likely morning. Clouds break for sun at times afternoon but also the chance of showers and thunderstorms, especially late-day from southwest to northeast. Highs 75-82. Dew point 60+. Wind variable up to 10 MPH becoming S.

SUNDAY NIGHT: Partly to mostly cloudy. Patchy fog. A shower possible. Lows 62-69. Dew point 60+. Wind SW under 10 MPH.

MONDAY: Variably cloudy. Showers possible. Chance of a thunderstorm. Highs 78-85. Dew point in 60s. Wind SW 5-15 MPH.

MONDAY NIGHT: Variably cloudy. Chance of a shower. Lows 61-68. Dew point near 60. Wind W up to 10 MPH.

Shower and thunderstorm chances focus around August 28 & 30, otherwise a mostly rain-free pattern. Temperatures near to above normal.

DAYS 11-15 (SEPTEMBER 1-5)

A couple disturbances may induce shower chances, but the pattern overall looks more dry than wet. Temperatures near normal.

DAYS 1-5 (AUGUST 21-25)

A quasi-stationary frontal boundary will host a pathway for a few low pressure disturbances to pass by our region through Sunday, keeping the weather somewhat unsettled through the weekend. It won’t rain all the time, but opportunities are there, particularly today into this evening and late Saturday night into Sunday morning, and favoring areas further east and south. A broad trough has to move from the region from west to east later in the weekend and early next week, and this will allow the pattern to warm slightly with more variable cloud cover, but with shower and thunderstorm opportunities Sunday and Monday, perhaps lingering into Tuesday.

TODAY: Mostly cloudy. Shower chances shift mainly I-95 belt southeastward. Highs 71-78. Dew point around 60. Wind variable up to 10 MPH.

TONIGHT: Mostly cloudy. Fog patches. Showers most likely I-95 belt southeastward. Lows 60-67. Dew point 60+. Wind variable up to 10 MPH.

SATURDAY: Mostly cloudy start with greatest shower chances I-95 belt southeastward, then a sun / cloud mix with a pop-up shower possible. Highs 76-83. Dew point near 60. Wind variable up to 10 MPH.

SATURDAY NIGHT: Mostly cloudy. Showers most likely overnight and favoring the I-95 belt eastward. Patchy fog. Lows 60-67. Dew point near 60. Wind S under 10 MPH.

SUNDAY: Variably cloudy. Early morning showers favor eastern areas. Fog patches during the morning. Afternoon pop-up showers and thunderstorms possible. Highs 78-85. Dew point in 60s. Wind SW 5-15 MPH.

SUNDAY NIGHT: Partly to mostly cloudy. Patchy fog. A shower possible. Lows 62-69. Dew point 60+. Wind SW under 10 MPH.

MONDAY: Mostly cloudy. Showers possible. Chance of thunderstorms. Highs 78-85. Dew point in 60s. Wind SW 5-15 MPH.

MONDAY NIGHT: Variably cloudy. Chance of a shower. Lows 61-68. Dew point near 60. Wind W up to 10 MPH.

DAYS 6-10 (AUGUST 26-30)

Watch for a couple disturbances and shower chances, but overall more dry times than wet ones. Temperatures near normal.

DAYS 11-15 (AUGUST 31 – SEPTEMBER 4)

A couple disturbances may induce shower chances, but the pattern overall looks more dry than wet. Temperatures near normal.

DAYS 1-5 (AUGUST 20-24)

A frontal boundary moves through our region today then settles just to the southeast Friday through the weekend. At the same time a broader trough of low pressure will move into the Northeast via the Midwest and Great Lakes and take through Monday to entirely cross our region. What this means is that the next 5 days will be unsettled, even though we start out with plenty of sunshine in the region today. What this doesn’t mean is that we see rain most of the time, although we can see some significant rainfall for portions of the region, depending on a set of details and how they take place. A little uncertainty with these can lead to quick-needed forecast adjustments as we move through this period of time, but here’s my current best shot on how I think it’ll play out. Today, as the front moves through, we see clouds move in as it passes by as a weak low pressure wave travels along it, and this brings us some generally light rainfall this evening / tonight. This first wave has been shown by some guidance to slow down and take its time moving by the region on Friday, being a focus for some heavier shower activity when acted on by limited sunshine. If this occurs, the greatest chance is in eastern CT, RI, and southeastern MA. A follow-up wave has been shown by guidance to take a range of tracks, some right over the region, some further southeast, some slower, some faster. My leaning is for a wave that brings the best shot of rain to southeastern MA, RI, and eastern CT later Friday to midday Saturday, with less of a chance to the north and northwest. When we get to Sunday and Monday, I suspect we’ll see a pattern of more scattered shower and possible thunderstorm activity with a bit more established southerly air flow in the region, along with a bit warmer and more noticeably humid air.

TODAY: Sun followed by clouds. Light rain chances increase later in the day especially south and west of Boston. Highs 77-84. Dew point 60+. Wind variable under 10 MPH.

TONIGHT: Cloudy. Light rain at times. Patchy fog forms. Lows 61-68. Dew point 60+. Wind variable under 10 MPH.

FRIDAY: Mostly cloudy to partly sunny. Shower chances shift mainly I-95 belt southeastward, with a few heavier showers and t-storms possible. Highs 75-82. Dew point around 60. Wind variable up to 10 MPH.

FRIDAY NIGHT: Mostly cloudy. Fog patches. Showers most likely I-95 belt southeastward. Lows 60-67. Dew point 60+. Wind variable up to 10 MPH.

SATURDAY: Mostly cloudy start with greatest shower chances I-95 belt southeastward, then a sun / cloud mix with a pop-up shower possible. Highs 76-83. Dew point near 60. Wind variable up to 10 MPH.

SATURDAY NIGHT: Partly cloudy. Patchy fog. Lows 60-67. Dew point near 60. Wind S under 10 MPH.

SUNDAY: Partly sunny. Afternoon pop-up showers and thunderstorms possible. Highs 78-85. Dew point in 60s. Wind SW 5-15 MPH.

SUNDAY NIGHT: Partly to mostly cloudy. Patchy fog. A shower possible. Lows 62-69. Dew point 60+. Wind SW under 10 MPH.

MONDAY: Mostly cloudy. Showers possible. Chance of thunderstorms. Highs 78-85. Dew point in 60s. Wind SW 5-15 MPH.

DAYS 6-10 (AUGUST 25-29)

Watch for a couple disturbances and shower chances, but overall more dry times than wet ones. Temperatures near normal.

DAYS 11-15 (AUGUST 30 – SEPTEMBER 3)

A couple disturbance may induce shower chances, but the pattern overall looks more dry than wet. Temperatures near normal.

DAYS 1-5 (AUGUST 19-23)

Much like yesterday, we start today with lots of stratus cloud cover, though a little more broken and with less fog around this time. This is due to a light southwesterly air flow bringing moisture in ahead of an approaching cold front. This southwesterly flow will strengthen somewhat during the day today into tonight, with a pretty nice, albeit fairly humid summer day today with the stratus clouds giving way to more sunshine. We’ll stay rain free today and this evening. As the aforementioned cold front moves slowly across the region Thursday, it can trigger a few showers and thunderstorms, but I am not anticipating widespread coverage or any severe weather. Once the front goes by, it will slow down and become quasi-stationary just to our south and east. We then watch for a wave of low pressure to form on and move along the boundary. The guidance has had some trouble resolving the timing on this. Current trends indicate that a bout of showery weather may impact at least southern and some eastern portions of our region later Friday to early Saturday before moving away. The next trough from the west will approach later Sunday and may bring another shower and thunderstorm opportunity later that day. This scenario would leave much of the weekend rain-free, however, so I am still somewhat optimistic.

Watch for a couple disturbances and shower chances, but overall more dry times than wet ones. Temperatures near normal.

DAYS 11-15 (AUGUST 29 – SEPTEMBER 2)

Unsettled weather is most likely toward the end of the period. Temperatures somewhat variable, averaging around normal.

DAYS 1-5 (AUGUST 18-22)

Low clouds and areas of fog are dominant as we start today with low level moisture trapped under an inversion in the lower atmosphere, and not enough wind to mix the air efficiently at first. This will change as weak low pressure to our east pulls away and the sun works on the atmosphere from above, eventually transforming our sky into a sun / cloud mix, although the colder air with upper low pressure just to our east can be enough to trigger a pop-up shower this afternoon, particularly from the I-95 belt eastward. Tranquil weather takes over tonight and Wednesday with plenty of sun and a warm-up during Wednesday as high pressure slides overhead then offshore. A southwesterly breeze will pick up later Wednesday as a cold front approaches our region from the northwest, but this front will not be in a grand rush to get by us, and will take most of the day Thursday to do so. This triggers a shower and thunderstorm chance that day, but I’m not expecting widespread coverage, nor am I expecting any severe weather. The front ambles offshore, barely, and slows to a crawl, or stalls completely, as we move through Friday into Saturday. Currently, I am still anticipating this front to be just far enough to the southeast so that high pressure can get close enough to give us fair weather those days. The forecast gets tricky here. We’ll also have to watch an initial low pressure wave moving along the front on Saturday that I do expect to stay offshore.

TODAY: Abundant low clouds and areas of fog give way to a mix of sun and clouds. A pop-up shower possible this afternoon, especially southeastern NH, eastern MA, and RI, but only isolated coverage. Highs 75-82. Dew point lowers to sub-60. Wind N to E up to 10 MPH.

TONIGHT: Partly cloudy. Patchy fog. Lows 58-65. Dew point upper 50s. Wind variable under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 80-87 except 73-80 Cape Cod. Dew point increases to lower 60s. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Patchy fog. Lows 62-69. Dew point 60+. Wind SW up to 10 MPH.

THURSDAY: Variably cloudy. Probable showers. Chance of thunderstorms. Highs 77-84. Dew point in 60s. Wind SW 5-15 MPH.

THURSDAY NIGHT: Partly cloudy. Lows 61-68. Dew point falls just under 60. Wind W up to 10 MPH.

FRIDAY: Partly sunny. Highs 75-82. Dew point sub-60. Wind variable up to 10 MPH.

FRIDAY NIGHT: Partly cloudy. Fog patches late night. Lows 60-67. Dew point near 60. Wind variable under 10 MPH.

SATURDAY: Partly sunny. Highs 76-83. Dew point near 60. Wind variable up to 10 MPH.

DAYS 6-10 (AUGUST 23-27)

August 23-25 are vulnerable to unsettled weather based on a front just to our south and a trough moving in from the west. I’m cautiously optimistic we finish most of the weekend on August 23 without rainfall and that it’s focused more on the two days that follow, but will monitor the evolution of the pattern here. Trend to fair and seasonable weather later in the period is the current expectation.

DAYS 11-15 (AUGUST 28 – SEPTEMBER 1)

A stretch of mainly fair weather and seasonable temperatures anticipated for the final days of August and the very start of September.

DAYS 1-5 (AUGUST 17-21)

Into the back half of August we go, and this week will start off on the wet, humid, and cool side today as dual low pressure passes by – one older center to our north, one newly developing center to our south. Showery weather will be most prominent this morning with less activity for the afternoon and evening, though cloud cover will remain dominant and keep temperature rise minimal as humidity stays high. Drying starts later tonight into Tuesday as the newer low moves offshore to our east and promotes a light northerly air flow, but some cold air aloft with the help of solar heating can help a few showers pop up Tuesday, primarily around the I-95 belt. A sliver of high pressure moves in Tuesday night and Wednesday giving us dry weather with a notable warm-up for Wednesday, along with a slight increase in humidity. A cold front will amble across the region on Thursday, bringing our region a shower and thunderstorm chance along with humid conditions, but it won’t be any warmer than Wednesday, maybe a tad cooler. Friday’s weather looks fair but the front that goes by Thursday may be slow to exit the South Coast so we’ll have to keep an eye on that. Right now I think high pressure will have enough push to keep it dry.

TODAY: Cloudy. Occasional showers and areas of fog morning. Chance of a shower this afternoon. Highs 68-75. Dew point 65+. Wind S shifts to E up to 10 MPH.

TONIGHT: Mostly cloudy. A shower possible evening. Patchy fog. Lows 61-68. Dew point 60+. Wind E shifts to N up to 10 MPH.

TUESDAY: Sun / cloud mix. A pop-up shower possible I-95 belt midday on. Highs 75-82, coolest coast. Dew point lowers to upper 50s. Wind N shifts to E up to 10 MPH.

TUESDAY NIGHT: Partly cloudy. Patchy fog. Lows 58-65. Dew point upper 50s. Wind variable under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 80-87 except 73-80 Cape Cod. Dew point increases to lower 60s. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Patchy fog. Lows 62-69. Dew point 60+. Wind SW up to 10 MPH.

THURSDAY: Variably cloudy. Probable showers. Chance of thunderstorms. Highs 77-84. Dew point in 60s. Wind SW 5-15 MPH.

THURSDAY NIGHT: Partly cloudy. Lows 61-68. Dew point falls just under 60. Wind W up to 10 MPH.

FRIDAY: Partly sunny. Highs 75-82. Dew point sub-60. Wind variable up to 10 MPH.

DAYS 6-10 (AUGUST 22-26)

The front previously talked about may be sitting just south of our region on the August 22-23 weekend. While my forecast was optimistic previously, it’s still partially so, but not as much, as we’ll have to watch a couple disturbances moving along the front that could deliver some showers to part of our region, particularly the South Coast / Cape Cod, during the weekend and even into early next week as well before we trend to fair weather as high pressure builds in later in the period. No major heat is expected.

DAYS 11-15 (AUGUST 27-31)

A stretch of mainly fair weather and seasonable temperatures anticipated for the final days of August.

DAYS 1-5 (AUGUST 16-20)

High pressure sits overhead early today then shifts offshore as low pressure moves into the Great Lakes. This starts a transition from sunshine and low humidity to increasing clouds and higher humidity, but neither one of those will be in a hurry to take over, so we still end up with a really nice day to finish off the weekend! The initial system moving into the Great Lakes redevelops just to our south on Monday and travels northeastward to a position offshore to our east by Monday night, wandering away Tuesday as another small area of high pressure builds our way behind it. This scenario brings us abundant cloudiness and scattered showers overnight tonight through Monday evening, but also much rain-free time. Tuesday’s weather features varying amounts of clouds and still the chance of a pop-up shower, but much of that day is dry. High pressure slides offshore Wednesday, and with the next approaching frontal system still well to our northwest, we’ll have a very nice summer day. The front to the northwest then does make its way into our region Thursday at which time we will see a return of shower and thunderstorm chances.

TODAY: Sunshine, then increasing clouds later in the day. Highs 76-83, coolest coast. Dew point rises to 60+ by later in the day. Wind variable up to 10 MPH with coastal sea breezes by midday, then S 5-15 MPH by late-day.

TONIGHT: Mostly cloudy. Scattered showers and patchy fog overnight. Lows 62-69. Dew point 60+. Wind S up to 10 MPH becoming variable.

MONDAY: Mostly cloudy. Scattered showers. Patchy fog early. Highs 68-75. Dew point in 60s. Wind variable to E up to 10 MPH, shifting to N late-day.

MONDAY NIGHT: Clouds linger. Patches of fog. Lows 60-67. Dew point 60+. Wind N up to 10 MPH.

TUESDAY: Intervals of clouds and sun. A pop-up shower possible, mainly near I-95 in the afternoon. Highs 75-82. Dew point sub-60. Wind N shifts to E up to 10 MPH.

TUESDAY NIGHT: Mostly clear. Patchy ground fog. Lows 53-60. Dew point under 55. Wind calm.

WEDNESDAY: Mostly sunny. Highs 73-80 South Coast / Cape Cod, 80-87 elsewhere. Dew point climbs to around 60. Wind variable to S up to 10 MPH.

WEDNESDAY NIGHT: Clear evening. Clouds overnight. Lows 61-68. Dew point near 60. Wind SW up to 10 MPH.

THURSDAY: Variably cloudy. Probable showers. Chance of thunderstorms. Highs 75-82. Dew point in 60s. Wind SW 5-15 MPH.

DAYS 6-10 (AUGUST 21-25)

Fair weather early to mid period which, based on current expectations, includes the August 22-23 weekend. Unsettled weather chances return late in the period. Lower humidity late next week, higher humidity follows. No major heat indicated.

DAYS 11-15 (AUGUST 26-30)

A stretch of mainly fair weather and seasonable temperatures expected toward month’s end.

DAYS 1-5 (AUGUST 15-19)

High pressure from Canada brings us pleasantly mild, dry weather with low humidity today and as it crests over our region, tonight ends up feeling rather cool in comparison to many recent warmer nights. Sunday, high pressure shifts offshore while it still has enough influence to give us a nice summer day, you’ll notice an up-tick in the humidity level by later in the day along with increasing cloud cover ahead of low pressure moving into the Great Lakes. This low pressure area gives us our next round of unsettled weather later Sunday night and Monday as it moves eastward and redevelops just south of our region. That conglomeration during transition will bring us episodic showery weather for 12 to 18 hours from around midnight Sunday night to sometime between noon and the end of the afternoon on Monday before it exits to the east. Behind it, high pressure returns Tuesday with generally fair weather, although lingering low level moisture left behind by the rainfall and heated by the sun will trigger some pop-up clouds to mix with the sun. High pressure shifts offshore Wednesday with sunshine and a light southerly breeze which will bring a tad bit more humidity back again, but not that noticeable with modest afternoon warmth after a somewhat cool start to the day.

TODAY: Mostly sunny. Highs 75-82. Dew point upper 40s to 50. Wind NW 5-15 MPH.

TONIGHT: Mostly clear. Lows 53-60. Dew point near 50. Wind variable under 10 MPH.

SUNDAY: Sunshine, then increasing clouds later in the day. Highs 76-83, coolest coast. Dew point rises to 60+ by later in the day. Wind variable up to 10 MPH with coastal sea breezes by midday, then S 5-15 MPH by late-day.

SUNDAY NIGHT: Mostly cloudy. Showers arrive west to east including the chance of a thunderstorm. Areas of fog overnight. Lows 65-72. Dew point near 65. Wind S 5-15 MPH.

MONDAY: Mostly cloudy. Episodes of showers and possibly a thunderstorm, tapering off during the afternoon southwest to northeast. Highs 72-79. Dew point 60s. Wind variable to E up to 10 MPH, shifting to N late-day.

MONDAY NIGHT: Clearing but ground fog patches around. Lows 55-62. Dew point falls under 55 by dawn. Wind N up to 10 MPH.

TUESDAY: Mostly sunny to partly cloudy. Highs 80-87, cooler some coastal areas. Dew point near 50. Wind N to variable up to 10 MPH with coastal sea breezes.

TUESDAY NIGHT: Mostly clear. Lows 53-60. Dew point near 50. Wind calm.

WEDNESDAY: Mostly sunny. Highs 73-80 South Coast / Cape Cod, 80-87 elsewhere. Dew point climbs to around 60. Wind S 5-15 MPH.

DAYS 6-10 (AUGUST 20-24)

Trough / frontal system brings a shower and thunderstorm chance to the region during August 20. Generally dry weather after this with high pressure keeping unsettled weather off to our south, but this may change toward the end of the period when we’ll have to watch for some unsettled weather.

DAYS 11-15 (AUGUST 25-29)

Best opportunity for unsettled weather starts the period with mainly fair weather following this. Temperatures mostly around seasonable levels.
