DAYS 1-5 (SEPTEMBER 9-13)

Low pressure approaches today, passes north of our region tonight, and departs to the east Thursday. Its warm front brings us a period of rain this evening, favoring areas north of I-90. Its cold front brings showers mainly during the few hours either side of sunrise Thursday, favoring the earlier part of that window, from west to east. Humidity edges up today, goes up more quickly tonight and early Thursday, then lowers again later Thursday as a wedge of subtropical air moves through with the passing system. High pressure builds in Friday and moves across the region Saturday providing fair weather with low humidity. The high slides offshore by Sunday when humidity comes back along with some clouds and a shower chance, though much of that day does look rain-free.

TODAY: Mostly cloudy. Rain chance by late-day especially north and west of Boston. Highs 68-75. Wind variable up to 10 MPH becoming SE to S 5-15 MPH.

TONIGHT: Cloudy evening with a period of rain, favoring north of I-90. Additional showers overnight. Areas of fog. Lows 63-70. Dew point spikes over 60. Wind S to SW up to 10 MPH.

THURSDAY: Mostly cloudy with shower chances early, then a sun / cloud mix. Humid morning, then drying. Highs 78-85. Wind SW 5-15 MPH shifting to W.

THURSDAY NIGHT: Partly cloudy. Lows 51-58. Wind W to NW 5-15 MPH.

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

FRIDAY NIGHT: Mostly clear. Lows 46-53. Wind N under 10 MPH.

SATURDAY: Sunny. Highs 66-73. Wind N to variable up to 10 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 50-57. Wind SW up to 10 MPH.

SUNDAY: Partly sunny. Chance of a shower. Highs 71-78. Wind S 5-15 MPH.

DAYS 6-10 (SEPTEMBER 14-18)

Above normal temperatures early next week until a front goes by between late September 15 and early September 16, returning dry and seasonable weather to the region. Shower chances with the frontal passage, otherwise a mainly dry pattern.

DAYS 11-15 (SEPTEMBER 19-23)

Shower chances limited, dry weather dominant. Some up-and-down temps but no extremes seen. The autumnal equinox is at 8:05 p.m. EDT on September 22.

DAYS 1-5 (SEPTEMBER 8-12)

Trough swings through today but you’ll hardly notice it other than some clouds passing by in the sky. Otherwise, it’s a pretty nice September day with mild and comfortably dry air. Unsettled weather is coming though as a low pressure area dives east southeastward and passes through our region later Wednesday through early Thursday. Its warm front gives our area a round of rainfall Wednesday evening. Its cold front follows it with showers Thursday morning. This quick mover is then gone and we dry out the remainder of Thursday, although the frontal boundary slows just enough with a wave of low pressure moving along it to bring the chance of some early morning showers on Friday near the South Coast. Otherwise, dry weather will be dominant here on Friday and Saturday as high pressure builds back in.

TODAY: Sun and passing clouds. Highs 73-80. Wind W 5-15 MPH shifts to NW.

TONIGHT: Clear, then high clouds arrive overnight. Inland low elevation fog patches. Lows 50-57. Wind N under 10 MPH then calm.

WEDNESDAY: Increasing clouds. Rain chance by late-day especially north and west of Boston. Highs 68-75. Wind variable up to 10 MPH becoming SE to S 5-15 MPH.

WEDNESDAY NIGHT: Cloudy. A period of rain. Areas of fog. Lows 60-67. Wind S to SW up to 10 MPH.

THURSDAY: Mostly cloudy with showers likely until midday including a slight chance of a thunderstorm. Partly cloudy afternoon. Humid morning, then drying. Highs 72-79. Wind SW 5-15 MPH shifting to W.

THURSDAY NIGHT: Partly cloudy. Lows 51-58. Wind W to NW 5-15 MPH.

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

FRIDAY NIGHT: Mostly clear. Lows 46-53. Wind N under 10 MPH.

SATURDAY: Sunny. Highs 66-73. Wind N to variable up to 10 MPH.

DAYS 6-10 (SEPTEMBER 13-17)

High pressure slips offshore to end the weekend and the beginning of next week. A frontal boundary gets closer from the northwest but this time a southwesterly flow aloft for a few days will keep it from whipping through, instead keeping our region on the warmer side of it until a low goes by to the north and finally pulls it by the region, allowing drier, cooler weather to settle in for later in the period.

DAYS 11-15 (SEPTEMBER 18-22)

Down the home stretch of astronomical summer we go with a pattern that features limited shower chances and a gradual cooling trend. The autumnal equinox is at 8:05 p.m. EDT on September 22.

DAYS 1-5 (SEPTEMBER 7-11)

High pressure builds as upper level low pressure departs, resulting in fair, pleasant weather for today. While many folks use this as a travel day and not a day to enjoy, at least the weather favors travel! Our nice weather will continue on Tuesday even though a weak trough will scoot through the region with some clouds. You’ll find it a bit warmer than today. The outlook remains the same heading into midweek with a low pressure area set to move east southeast in a northwesterly flow aloft. This will cloud us up on Wednesday with episodes of showery weather Wednesday night and Thursday. This system exits by Friday and high pressure builds in that day with fair weather returning. A humidity spike accompanies Thursday’s unsettled weather, but it will be short-lived when a batch of dry air follows it quickly on Friday.

TODAY – LABOR DAY: Sun and passing clouds. Highs 71-78. Wind NW 5-15 MPH.

TONIGHT: Mostly clear. Lows 52-59. Wind W up to 10 MPH.

TUESDAY: Sunny morning then a sun / cloud mix. Highs 73-80. Wind SW 5-15 MPH shifts to NW late.

TUESDAY NIGHT: Clearing. Inland low elevation fog patches. Lows 50-57. Wind N under 10 MPH then calm.

WEDNESDAY: Increasing clouds. Shower chance by late-day especially north and west of Boston. Highs 68-75. Wind variable up to 10 MPH becoming SE to S 5-15 MPH.

WEDNESDAY NIGHT: Cloudy. Scattered showers. Areas of fog. Lows 60-67. Wind S to SW up to 10 MPH.

THURSDAY: Mostly cloudy with showers likely through midday including a slight chance of a thunderstorm. Partly sunny with an additional shower possible in the afternoon. Humid. Highs 72-79. Wind SW 5-15 MPH shifting to W.

THURSDAY NIGHT: Partly cloudy. Lows 51-58. Wind W to NW 5-15 MPH.

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

DAYS 6-10 (SEPTEMBER 12-16)

High pressure moves overhead then offshore between September 12 and 14 with fair weather and typical end-of-summer cooler mornings but warmer afternoons with notable temperature spreads from lows to highs. Watching the next frontal system for a shower potential later in the period – September 15 to early 16. If this front is slow enough, September 15 can end up a very warm day.

DAYS 11-15 (SEPTEMBER 17-21)

The final five full days of astronomical summer carry a mainly fair weather pattern with 1 or 2 brief interruptions for showers from passing systems. Temperature ups and downs but with an overall cooling trend.

DAYS 1-5 (SEPTEMBER 6-10)

A speed-bump in our weekend in the form of showers from early to mid morning today as a more vigorous than expected disturbance wheels through with the upper trough over our region. This does give way to fair weather with a sun cloud mix taking over from north to south by later morning onward. The rest of the forecast is basically unchanged with a nice Labor Day ahead, a quick-moving trough bringing a shower threat the first part of Tuesday, then the next system in a northwest flow bringing us unsettled weather later Wednesday into Thursday. More details on that on the next blog update!

TODAY: Lots of clouds and scattered showers into mid morning then a sun / cloud mix. Highs 68-75. Wind N to NE 5-15 MPH.

TONIGHT: Mostly clear. Lows 48-55. Wind N up to 10 MPH.

MONDAY – LABOR DAY: Sun and passing clouds. Highs 71-78. Wind NW 5-15 MPH.

MONDAY NIGHT: Variably cloudy. Lows 51-58. Wind W 5-15 MPH.

TUESDAY: Variably cloudy with passing showers possible until midday, then more sunshine. Highs 70-77. Wind W shifting to N 5-15 MPH.

TUESDAY NIGHT: Clear. Fog patches interior low elevations. Lows 50-57. Wind variable under 10 MPH.

WEDNESDAY: Increasing clouds. Shower chance returns late-day. Highs 68-75. Wind variable up to 10 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Showers likely. Chance of a thunderstorm. Lows 60-67. Wind SW 5-15 MPH.

THURSDAY: Variably cloudy. Possible showers. Highs 68-75. Wind W 5-15 MPH.

DAYS 6-10 (SEPTEMBER 11-15)

High pressure moves in then overhead then offshore between September 11 and 14 with fair, cooler weather at first then a warm-up. Next disturbance brings the chance of unsettled weather by the end of the period.

DAYS 11-15 (SEPTEMBER 16-20)

Unsettled weather episodes should be brief early and again later in the period in an otherwise mostly dry pattern with some temperature ups and downs but nothing extreme.

DAYS 1-5 (SEPTEMBER 5-9)

The large scale pattern across the country features a ridge of high pressure in the central US, which leaves our region in a northwest flow pattern on the east side of the ridge, with more amplification as an upper trough sits over our region now and drifts eastward into Atlantic Canada and the adjacent waters through the weekend. The flow around the back side of a surface low south of Nova Scotia will send some cloudiness into our region at times today and part of Sunday, which will be added to at times by diurnal cloud development. Pop-up shower chances are greatest west of I-95 this afternoon with limited coverage. Any area that does see a shower would only have it last a short time before it moved on. A trough may bring a quick-moving batch of showers in the pre-dawn hours to southeastern NH and northeastern MA Sunday, and the chance of a diurnal pop-up shower that day dwindles to nearly zero. Monday’s weather features more sunshine and less cloudiness and the rain chance drops to nil. So all in all, the holiday weekend is not bad, featuring mostly dry weather, a cooling trend on a north to northeast flow, and low humidity. Reminder that the north to northeast fetch will create rougher surf, some larger swells, and rip-current risks especially at north-facing and east-facing shores through the weekend. A trough swings through first thing Tuesday with clouds and perhaps a shower, and then clouds increase from the northwest ahead of the next approaching disturbance Wednesday. Guidance has trended faster in the medium range with that disturbance, indicating a shower chance may exist before that day is over. I’m leaning in that direction based on the type of pattern we will be in.

TODAY: Sun / cloud mix with clouds more dominant. A passing shower possible. Highs 68-75. Wind N to NE 5-15 MPH.

TONIGHT: Variably cloudy. Shower chance is best overnight southeastern NH to northeastern MA. Lows 53-60. Wind N up to 10 MPH.

SUNDAY: Sun / cloud mix with sun more dominant. Highs 68-75. Wind N to NE 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 48-55. Wind N up to 10 MPH.

MONDAY – LABOR DAY: Sun dominates. Highs 71-78. Wind NW 5-15 MPH.

MONDAY NIGHT: Variably cloudy. Lows 51-58. Wind W 5-15 MPH.

TUESDAY: Clouds and a possible shower early, then clearing. Highs 70-77. Wind W shifting to N 5-15 MPH.

TUESDAY NIGHT: Clear. Fog patches interior low elevations. Lows 50-57. Wind variable under 10 MPH.

WEDNESDAY: Increasing clouds. Shower chance returns late-day. Highs 68-75. Wind variable up to 10 MPH.

DAYS 6-10 (SEPTEMBER 10-14)

Disturbances in a northwest flow are roughly timed to pass through early September 10 and late September 13 to early September 14 when brief shower threats occur, otherwise a mainly dry pattern with somewhat variable but overall near to slightly above normal temperatures.

DAYS 11-15 (SEPTEMBER 15-19)

Up-and-down temperature pattern with a couple unsettled weather episodes with quick-passing systems as the pattern remains generally the same in the waning days of astronomical summer.

DAYS 1-5 (SEPTEMBER 4-8)

A disturbance passing by to the south brings some showers, even a few downpours, to the South Coast and Islands early today, while early to mid morning stratus / fog blanket a good portion of the region too. After this, we see more sun, mixed with clouds, and only a slight chance of a stray pop-up shower, so the day turns out mainly dry and on the warm side after the start described in my first sentence. Our Labor Day Weekend forecast remains decent. Pop-up showers are possible Saturday in response to upper level low pressure overhead. Surface low pressure to our east Saturday and Sunday brings us a cooling north to northeast flow. This air flow over the Gulf of Maine will enhance surf on north-facing and east-facing shores, so if you have beach and boating plans this weekend, keep that in mind. Monday will see the coolest morning, but the largest temperature rebound of the three “weekend” days, though some cloudiness may increase from the north late in the day in response to an approaching weak through. But, other than that pop-up shower threat Saturday, we will enjoy dry weather for the three day stretch. A low pressure trough passing by early Tuesday may produce a brief shower otherwise that day looks fair too.

TODAY: Low clouds / foggy areas much of the region, while heavier clouds and a few showers / downpours pass through the South Coast region, followed by a sun / cloud mix with a chance of a pop-up shower this afternoon. Highs 77-84. Wind NW up to 10 MPH.

TONIGHT: Partly cloudy. Lows 53-60. Wind N up to 10 MPH.

SATURDAY: Sun / cloud mix. A pop-up shower possible. Highs 68-75. Wind N to NE 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 53-60. Wind NE under 10 MPH.

SUNDAY: Sun / cloud mix. Highs 68-75. Wind NE to N 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 48-55. Wind N up to 10 MPH.

MONDAY: Sun followed by clouds. Highs 71-78. Wind NW 5-15 MPH.

MONDAY NIGHT: Variably cloudy. Lows 51-58. Wind W 5-15 MPH.

TUESDAY: Clouds and a possible shower early, then clearing. Highs 70-77. Wind W shifting to N 5-15 MPH.

DAYS 6-10 (SEPTEMBER 9-13)

Disturbances in a northwest flow are roughly timed to pass through early September 10 and 13 when brief shower threats occur, otherwise a mainly dry pattern with somewhat variable but overall near to slightly above normal temperatures.

DAYS 11-15 (SEPTEMBER 14-18)

Up-and-down temperature pattern with a couple unsettled weather episodes with quick-passing systems indicated for mid month.

DAYS 1-5 (SEPTEMBER 3-7)

This forecast takes us up through Labor Day Weekend, aka the next of several endings of summer, depending on how you mark it. Anyway, we start with an unsettled day today as a disturbance moving through causes widespread showers and potential embedded thunderstorms to start the morning, which will then end west to east by mid to late morning, lastly on Cape Cod, with some partial clearing following. With a cold front still to cross the region this afternoon, and a warm, humid air mass in place, we’ll have to watch for additional showers and thunderstorms to develop and move through later today. These, where they occur, should be relatively short-lived but can cause brief gusty wind and downpours. Drier air arrives tonight with clearing. Friday will still be a fairly warm day but with lower humidity, and the contrast between sun-heated land and colder air arriving aloft can help an isolated shower pop-up in the afternoon, but coverage would be isolated. As we move through the Labor Day Weekend, we still have the upper trough aloft but a cooler north to northeast flow at the surface Saturday and Sunday. A pop-up shower is not impossible Saturday, but we see mainly dry weather. Monday, high pressure noses in with fair weather, but the upper low is only slightly shifted to the east by then, and another surface trough will drop into the northerly flow behind it, bringing more clouds to our region to end the holiday weekend after a brighter start to the day.

TODAY: Cloudy start with areas of fog and widespread showers, some heavy, with a chance of thunder. Clouds break for sun later morning into afternoon but a shower or thunderstorm possible later in the day from west northwest to east southeast across the region. Highs 75-82. Humid. Wind S to SW up to 10 MPH, but can be variable and gusty around any late-day showers/storms.

TONIGHT: Clearing. Lows 55-62. Wind W up to 10 MPH

FRIDAY: Sun / cloud mix. A pop-up shower possible. Highs 77-84. Wind NW up to 10 MPH.

FRIDAY NIGHT: Partly cloudy. Lows 53-60. Wind N up to 10 MPH.

SATURDAY: Sun / cloud mix. A pop-up shower possible. Highs 68-75. Wind N to NE 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 53-60. Wind NE under 10 MPH.

SUNDAY: Sun / cloud mix. Highs 68-75. Wind NE to N 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 52-59. Wind N up to 10 MPH.

MONDAY: Sun followed by clouds. Highs 70-77. Wind N 5-15 MPH.

DAYS 6-10 (SEPTEMBER 8-12)

Disturbances in a northwest flow are roughly timed to pass through early September 8 and September 10 when brief shower threats occur, otherwise a mainly dry pattern with somewhat variable but overall near to slightly above normal temperatures.

DAYS 11-15 (SEPTEMBER 13-17)

Up-and-down temperature pattern with a couple unsettled weather episodes with quick-passing systems indicated for mid month.

DAYS 1-5 (SEPTEMBER 2-6)

Most of the rain from this unsettled stretch fell yesterday, on the first of September. There was enough drying behind that disturbance for breaks in the clouds last night despite areas of low clouds and fog (which will dissipate this morning), and clouds can still break for sun at times during the day today. The next round of rainfall, the remains of an upstream storm complex, will pass through our region late tonight and be largely offshore by sunrise Thursday. That day, warmer, more humid air does get in, and with upper level low pressure overhead and a frontal boundary having been pushed north of the region but still having to sag back through to the south, we can see a few showers and thunderstorms that afternoon. Friday’s outlook is largely the same, with upper low pressure lingering and a chance of a pop-up shower, otherwise a drier, cooler trend. Labor Day Weekend’s first and second day are looking decent. I’ve backed-off on forecasting pop-up showers to more of a diurnal clouds sharing the sky with sun outlook, seasonable temperatures, and low humidity.

TODAY: More clouds than sun. Foggy areas early. Highs 66-73. Wind variable to E up to 10 MPH.

TONIGHT: Mostly cloudy. Showers likely, mainly overnight. Lows 56-63. Wind variable up to 10 MPH.

THURSDAY: Partial sunshine. A pop-up shower or thunderstorm possible in the afternoon. Highs 70-77. Wind SW up to 10 MPH, a few stronger gusts near any storms.

THURSDAY NIGHT: Partly cloudy. A shower possible early, especially southeastern MA and RI. Lows 55-62. Wind NW 5-15 MPH.

FRIDAY: Sun / cloud mix. A pop-up shower possible. Highs 73-80. Wind NW up to 10 MPH.

FRIDAY NIGHT: Partly cloudy. Lows 53-60. Wind N up to 10 MPH.

SATURDAY: Sun / cloud mix. Highs 68-75. Wind N 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 53-60. Wind N under 10 MPH.

SUNDAY: Sun / cloud mix. Highs 68-75. Wind N 5-15 MPH.

DAYS 6-10 (SEPTEMBER 7-11)

Labor Day (September 7) sees clouds increase ahead of an approaching frontal system from the northwest which then pushes through with clearing the following day. Next round of unsettled weather is eyed for later September 9 into September 10 with fair weather following. Temperatures somewhat variable, but no extremes indicated.

DAYS 11-15 (SEPTEMBER 12-16)

Up-and-down temperature pattern with a couple unsettled weather episodes with quick-passing systems heading into mid month.

DAYS 1-5 (SEPTEMBER 1-5)

September opens with a stretch of unsettled weather as a couple disturbances move through the Northeast in a west northwest flow aloft. The first one brings fairly widespread showers to our region this morning into midday before tapering off. The second one’s rainfall is to be concentrated in the late night Wednesday to early morning Thursday time frame, with a fairly cloudy but rain-free day between that on Wednesday. Behind the second batch of wet weather Thursday comes breaks with higher humidity as we’re briefly in the warm sector of the second system before a cold front brings a shower and thunderstorm chance later that day. By Friday and Saturday, the system has exited and high pressure attempts to build in at the surface while upper level low pressure lingers aloft. This means that each of those days carries the chance of pop-up showers, but many more dry hours then not, along with cooler weather.

TODAY: Mostly cloudy. Showers likely, especially mid morning to midday before tapering northwest to southeast. Highs 67-74. Wind SE up to 10 MPH.

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

WEDNESDAY: Mostly cloudy. Chance of a shower. Patchy fog early. Highs 67-74. Wind variable to E 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Showers likely mainly overnight. Lows 56-63. Wind variable up to 10 MPH.

THURSDAY: Mostly cloudy with showers likely early, then clouds break for sun at times with an additional shower or thunderstorm chance in the afternoon. Highs 70-77. Wind SW up to 10 MPH.

THURSDAY NIGHT: Partly cloudy. A shower possible early, especially southeastern MA and RI. Lows 55-62. Wind NW 5-15 MPH.

FRIDAY: Sun / cloud mix. A pop-up shower possible. Highs 68-75. Wind N 5-15 MPH.

FRIDAY NIGHT: Partly cloudy. Lows 53-60. Wind N up to 10 MPH.

SATURDAY: Sun / cloud mix. A pop-up shower possible. Highs 66-73. Wind N 5-15 MPH.

DAYS 6-10 (SEPTEMBER 6-10)

Decreased but non-zero pop-up shower chance September 6. Next frontal system arrives late September 7 with shower chances, mainly at night, so the final two days of Labor Day Weekend are also mainly dry. Shower chances early September 8 and again September 10 with passing frontal systems. Temperatures near to slightly above normal.

DAYS 11-15 (SEPTEMBER 11-15)

Up-and-down temperature pattern with a couple unsettled weather episodes with quick-passing systems heading into mid month.

DAYS 1-5 (AUGUST 31 – SEPTEMBER 4)

This final day of August will feature a little September preview as a frontal boundary settles to our south and some cooler air enters our region from eastern Canada. It will be a nice day though with lots of sun in general, though it will be filtered by high cloudiness for a good part of the day the further south and southwest you are. We also have some fog patches in valley locations to start the day, but that will quickly dissipate. Coolest air will be along east-facing and north-facing shores today with a light northeasterly air flow. We open September with some unsettled weather as a series of disturbances move through the Northeast on a northwesterly air flow aloft, bringing episodic showers Tuesday (favoring morning-midday) and Wednesday (favoring evening and night), with one final warm front / cold front passage with a wavy frontal boundary on Thursday bringing additional shower and thunderstorm chances. On Friday, the mess exits, but upper level low pressure can stick kick off a pop-up shower as cooler air moves in.

TODAY: Filtered sun CT, RI, south central MA with brighter sun elsewhere. Any early fog patches vanish. Highs 75-82, coolest coast. Wind NE 5-15 MPH.

TONIGHT: Clouds increase. Fog patches in valleys. Showers arrive northwest to southeast toward dawn. Lows 60-67. Wind SE up to 10 MPH.

TUESDAY: Mostly cloudy. Showers likely, especially morning to midday before tapering northwest to southeast. Highs 67-74. Wind SE up to 10 MPH.

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

WEDNESDAY: Mostly cloudy. Chance of showers. Patchy fog early. Highs 67-74. Wind variable to E 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Showers likely. Lows 56-63. Wind variable up to 10 MPH.

THURSDAY: Partly sunny. A shower or thunderstorm possible. Highs 70-77. Wind SW up to 10 MPH.

THURSDAY NIGHT: Partly cloudy. A shower possible early, especially southeastern MA and RI. Lows 55-62. Wind NW 5-15 MPH.

FRIDAY: Sun / cloud mix. A pop-up shower possible. Highs 68-75. Wind N 5-15 MPH.

DAYS 6-10 (SEPTEMBER 5-9)

Labor Day Weekend – surface high pressure to the north, weak upper trough over the region results in near to below normal temperatures with mainly dry weather but a sun / cloud mix during each of the days. Cannot rule out pop-up diurnal showers favoring Saturday and Sunday but with isolated coverage. Indications for high pressure dominating with fair weather later in the period including a warming trend.

DAYS 11-15 (SEPTEMBER 10-14)

A little more up-and-down temp pattern with a couple unsettled weather threats during this period, but far too soon for any detail.

DAYS 1-5 (AUGUST 30 – SEPTEMBER 3)

High pressure slips offshore and a disturbance approaches from the west northwest today, bringing in more cloud cover. While shower chances do increase later today, I’m not looking for widespread activity and the greatest chance will take place after sunset this evening. This disturbance moves beyond the region and Monday will feature fair weather with a narrow area of high pressure moving into the region. The west northwest flow pattern in place is a pretty fast one, and the next two disturbances follow in rapid succession bringing us a period of unsettled weather to start September on Tuesday and Wednesday. The second of these will be a big elongated on its back side so that while we see some partial clearing on Thursday, it will be a bit more humid and I can’t rule out an additional pop-up shower or thunderstorm that afternoon, based on current expecting timing for day 5. One thing we won’t be seeing: Late summer heat as in 90+. No sign of that.

TODAY: 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.

TONIGHT: Clouds dominate with a shower chance evening. Clouds decrease overnight. 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 to E up to 10 MPH.

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

WEDNESDAY NIGHT: Mostly cloudy. Showers likely. Lows 58-65. Wind variable up to 10 MPH.

THURSDAY: Partly sunny. A shower or thunderstorm possible. Highs 70-77. Wind SW up to 10 MPH.

DAYS 6-10 (SEPTEMBER 4-8)

Current trend is for a trough to depart on September 4 which a shower is possible, then for high pressure to bring fair weather for Labor Day Weekend and holding on through the end of the period. Temperatures near to slightly below normal to start, then trending warmer late period.

DAYS 11-15 (SEPTEMBER 9-13)

Fair weather to start then a trend toward unsettled weather thereafter. Temperatures trend cooler again.

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 6-10 (SEPTEMBER 1-5)

Unsettled weather as a trough passes by with shower chances September 1-2, followed by fair weather mid to late period. Temperatures near normal.

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.
