DAYS 1-5 (SEPTEMBER 9-13)

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

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

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

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

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

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

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

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

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

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

DAYS 6-10 (SEPTEMBER 14-18)

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

DAYS 11-15 (SEPTEMBER 19-23)

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

DAYS 1-5 (SEPTEMBER 8-12)

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

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

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

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

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

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

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

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

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

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

DAYS 6-10 (SEPTEMBER 13-17)

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

DAYS 11-15 (SEPTEMBER 18-22)

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

DAYS 1-5 (SEPTEMBER 7-11)

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

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

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

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

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

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

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

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

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

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

DAYS 6-10 (SEPTEMBER 12-16)

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

DAYS 11-15 (SEPTEMBER 17-21)

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

DAYS 1-5 (SEPTEMBER 6-10)

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

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

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

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

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

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

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

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

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

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

DAYS 6-10 (SEPTEMBER 11-15)

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

DAYS 11-15 (SEPTEMBER 16-20)

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

DAYS 1-5 (SEPTEMBER 5-9)

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

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

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

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

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

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

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

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

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

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

DAYS 6-10 (SEPTEMBER 10-14)

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

DAYS 11-15 (SEPTEMBER 15-19)

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

DAYS 1-5 (SEPTEMBER 4-8)

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

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

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

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

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

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

FRIDAY NIGHT: Variably cloudy. Patchy fog. Lows 55-62. Dew point middle to upper 50s. Wind SE under 10 MPH.

SATURDAY: Variably cloudy. Highs 71-78. Dew point rising to lower 60s. Wind SE up to 10 MPH.

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

SUNDAY: Variably cloudy. Chance of showers in the morning. Areas of fog early. Highs 70-77. Dew point 60+ in the morning, then falling through 50s. Wind S 5-15 MPH shifting to W.

DAYS 6-10 (SEPTEMBER 9-13)

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

DAYS 11-15 (SEPTEMBER 14-18)

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

DAYS 1-5 (SEPTEMBER 3-7)

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

TODAY: Sunny. Highs 68-75. Dew point in 40s. Wind W up to 10 MPH.

TONIGHT: Clear. Ground fog patches possible. Lows ranging from near 40 interior valleys to 50-55 urban areas. Dew point in 40s. Wind calm.

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

WEDNESDAY NIGHT: Clear. Ground fog patches possible. Lows 43-50 except milder urban centers. Dew point lower to middle 40s. Wind W under 10 MPH.

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

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

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

FRIDAY NIGHT: Variably cloudy. Patchy fog. Lows 55-62. Dew point middle to upper 50s. Wind SE under 10 MPH.

SATURDAY: Variably cloudy. Highs 71-78. Dew point rising to lower 60s. Wind SE up to 10 MPH.

DAYS 6-10 (SEPTEMBER 8-12)

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

DAYS 11-15 (SEPTEMBER 13-17)

Pattern looks quiet and slightly warmer mid month.

DAYS 1-5 (SEPTEMBER 2-6)

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

TODAY (LABOR DAY): Lots of clouds early, then increasing sunshine. Highs 71-78. Dew point falls through 50s. Wind NW to N 5-15 MPH.

TONIGHT: Clear. Patchy ground fog possible in lowest elevations. Lows 47-54, mildest urban centers. Dew point in 40s. Wind NW up to 10 MPH.

TUESDAY: Sunny. Highs 68-75. Dew point in 40s. Wind W up to 10 MPH.

TUESDAY NIGHT: Clear. Ground fog patches possible. Lows ranging from near 40 interior valleys to 50-55 urban areas. Dew point in 40s. Wind calm.

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

WEDNESDAY NIGHT: Clear. Ground fog patches possible. Lows 43-50 except milder urban centers. Dew point lower to middle 40s. Wind W under 10 MPH.

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

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

FRIDAY: Partly sunny. Highs 72-79, coolest coast. Dew point rising to 60+. Wind S to SE up to 10 MPH.

DAYS 6-10 (SEPTEMBER 7-11)

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

DAYS 11-15 (SEPTEMBER 12-16)

Pattern looks quiet and somewhat warmer mid month.

DAYS 1-5 (SEPTEMBER 1-5)

September starts off with a warm and moderately humid air mass in place. A trough can kick off a shower or thunderstorm in a few places from midday to late afternoon mainly from the I-90 belt southward. A cold front will cross the area tonight but it looks like any convective activity associated with it will largely diminish / dissipate before entering the WHW forecast area, other than maybe a stray shower or storm in southwestern NH or central MA sometime this evening. The front moves offshore by morning, and high pressure will build into the Great Lakes, delivering a cooler, dry air mass. Some clouds will pop up during the day Monday in response to a pool of colder air aloft, but not enough to result in any showers. High pressure will dominate with pleasant weather, chilly nights and mild days, Tuesday through Thursday. This pattern can result in late night and early morning fog patches over lower elevation locations where the temperature and dew point have the greatest chance of matching up, but any fog of this type tends to dissipate quickly as the sun climbs into the morning sky.

TODAY: Variably cloudy. Passing showers and a slight chance of a thunderstorm, favoring I-90 southward, midday through mid afternoon. Highs 75-82. Dew point middle to upper 60s. Wind SW 5-15 MPH.

TONIGHT: Variably cloudy evening with a slight chance of a shower or thunderstorm early mainly west of I-495 and north of I-90, then clearing. Lows 52-59. Dew point falling to near 50. Wind NW 5-15 MPH.

MONDAY (LABOR DAY): Sun and passing clouds. Highs 68-75. Dew point falling into 40s. Wind NW 5-15 MPH, a few higher gusts.

MONDAY NIGHT: Clear. A patch of ground fog possible in lowest elevations. Lows 47-54, mildest urban centers. Dew point in 40s. Wind NW up to 10 MPH.

TUESDAY: Sunny. Highs 68-75. Dew point in 40s. Wind W up to 10 MPH.

TUESDAY NIGHT: Clear. Ground fog patches possible. Lows ranging from near 40 interior valleys to 50-55 urban areas. Dew point in 40s. Wind calm.

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

WEDNESDAY NIGHT: Clear. Ground fog patches possible. Lows 43-50 except milder urban centers. Dew point lower to middle 40s. Wind W under 10 MPH.

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

DAYS 6-10 (SEPTEMBER 6-10)

Higher humidity returns late next week. What remains to be seen is whether or not there will be enough interaction between low pressure to the south and a trough from the west to bring a more significant rain chance into the region into the weekend. A lot of uncertainty in this outlook, so a lot of analysis, tweaking, and fine-tuning to come. The weather follow that period will be somewhat dependent on what happens during that period. A drier scenario would likely mean there was enough blocking high pressure to hold the next system up so that we’d have a shot at unsettled weather later in the period, while a wetter scenario early in the period would more likely lead to a period of fair weather for late period. The forecast method here is not just choosing a model and going with it.

DAYS 11-15 (SEPTEMBER 11-15)

Quick look at the mid September pattern still looks fairly quiet and may turn quite warm for a period of time, but re-evaluation needed based on what takes place before that.

DAYS 1-5 (AUGUST 31 – SEPTEMBER 4)

A warm front crosses the region this morning and introduces higher humidity and seasonably warm air for the opening day of the holiday weekend. Sun will be most limited west of I-95 while offshore high pressure helps fight the cloudiness and allows a little more sun in eastern locations. A trough and cold front approach tonight then cross the region on Sunday. The interaction of these with the humid air will bring up to a few rounds of showers and possibly a thunderstorm to any given location for about a 12 hour period from midnight to noon. However, most of the time during this window will be rain-free. The shower and thunderstorm chance drops during Sunday afternoon but does not go to zero. We’ll have to just keep an eye out for one more passing shower or storm, but odds are quite low. Sunday evening, the cold front will push through and introduce a cooler, dry air mass to the region, reinforced by a secondary cold frontal passage early Monday, making Labor Day a day with a hint of autumn in the air, but with fair weather, a breeze, and sunshine with passing clouds about. High pressure builds in with fair and pleasant weather Tuesday and Wednesday.

TODAY: Variably cloudy – most sun east of I-95. Highs 75-82. Dew point rising into 60s. Wind S up to 10 MPH.

TONIGHT: Considerably cloudy. Scattered showers and a slight chance of a thunderstorm increasing from west to east overnight. Patchy fog overnight. Lows 61-68. Dew point 60+. Wind S up to 10 MPH.

SUNDAY: Variably cloudy with a couple passing showers and possible thunderstorms in the morning. Partly sunny with a slight chance of an additional passing shower or thunderstorm in the afternoon. Highs 72-79. Dew point middle to upper 60s. Wind S 5-15 MPH, can be briefly variable and gusty around any showers/storms.

SUNDAY NIGHT: Partly cloudy to mostly clear. Lows 52-59. Dew point falling to near 50. Wind W 5-15 MPH.

MONDAY (LABOR DAY): Sun and passing clouds. Highs 68-75. Dew point falling into 40s. Wind NW 5-15 MPH, a few higher gusts.

MONDAY NIGHT: Clear. A patch of ground fog possible in lowest elevations. Lows 47-54, mildest urban centers. Dew point in 40s. Wind NW up to 10 MPH.

TUESDAY: Sunny. Highs 68-75. Dew point in 40s. Wind W up to 10 MPH.

TUESDAY NIGHT: Clear. Ground fog patches possible. Lows ranging from near 40 interior valleys to 50-55 urban areas. Dew point in 40s. Wind calm.

WEDNESDAY: Sunny. Highs 70-77. Dew point near 50. Wind W up to 10 MPH.

DAYS 6-10 (SEPTEMBER 5-9)

High pressure shifts eastward with fair weather and a warming trend early in the period. A weak trough approaches from the west while low pressure takes place south of New England later next week. While it’s uncertain, any interaction between these systems can draw wet weather northward from the aformentioned low, and bring a rain chance at some point next weekend. Something to watch and different from what was in yesterday’s outlook.

DAYS 11-15 (SEPTEMBER 10-14)

Overall pattern looks fairly quiet and mild heading into mid September, but will have to re-evaluate depending on what happens prior.

DAYS 1-5 (AUGUST 30 – SEPTEMBER 3)

High pressure in southeastern Canada provides a relatively cool easterly air flow but nice weather today. The high pushes to the southeast and a warm front crosses the region Saturday with more clouds, perhaps an early-day shower in a few locations, a return to higher humidity, and a slight warm up. A cold front will cross the region early Sunday with a shower threat from this front beginning Saturday evening, but mostly during the first 12 hours of Sunday. Beyond that, high pressure builds in and provides fair weather for the remainder of the holiday weekend as well as Tuesday.

TODAY: Mostly sunny to partly cloudy. Highs 68-75. Dew 50s. Wind E up to 10 MPH.

TONIGHT: Partly cloudy. Patchy ground fog. Lows 55-62. Dew point in 50s. Wind variable to SE under 10 MPH.

SATURDAY: Partly sunny. A shower possible mainly south of I-90 morning. Highs 75-82. Dew point rising to 60s. Wind S 5-15 MPH.

SATURDAY NIGHT: Variably cloudy. A possible shower in the evening. Showers and possible thunderstorms overnight. Patchy fog overnight. Lows 62-69. Dew point 60s. Wind SW 5-15 MPH.

SUNDAY: Lots of clouds with showers ending west to east in the morning. Sun/cloud mix thereafter. Highs 71-78. Dew point falls below 60. Wind W 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 52-59. Dew point near 50. Wind W 5-15 MPH.

MONDAY (LABOR DAY): Sun and passing clouds. Highs 70-77. Dew point 50s. Wind W 5-15 MPH, higher gusts, shifting to NW.

MONDAY NIGHT: Clear. Patchy late-night ground fog interior lower elevations. Lows 51-58. Dew point near 50. Wind W under 10 MPH.

TUESDAY: Sunny. Highs 71-78. Dew point near 50. Wind W up to 10 MPH.

DAYS 6-10 (SEPTEMBER 4-8)

High pressure will dominate with generally fair weather during much of next week. Temperatures near to slightly above normal.

DAYS 11-15 (SEPTEMBER 9-13)

A mid-period unsettled interlude possible, otherwise a mostly dry and seasonably mild late summer pattern.

DAYS 1-5 (AUGUST 29 – SEPTEMBER 2)

High pressure stretching from Quebec to Atlantic Canada will provide dry, cooler weather today and Friday. As the high shifts more to the southeast, we’ll start to experience some weather changes heading into the holiday weekend. For the final day of August on Saturday we’ll see some cloudiness return, but also some sun, as a warm front lifts through the region. This front can produce a few showers mainly across southern areas Saturday morning, but most areas will not see this activity. The front’s parenting low will track north of our region Saturday night into Sunday, dragging a cold front through. The timing of this front is such that the main shower threat will occur during the first 12 hours of Sunday from west to east, but I can’t rule out a few spot showers ahead of that sometime on Saturday evening. I do think most of Saturday’s daylight hours will be dry well ahead of the cold front, along with Sunday afternoon after the front pushes through. A spike in humidity and a warm-up will occur Saturday, and Sunday will remain on the warm side but with lowering humidity behind the front after a muggy start to the day. Labor Day, another cold front will move through but this one will have very limited moisture to work with and a spot shower chance is a stretch. We’ll probably just see some some passing clouds and a wind shift, and in a symbolic way the feel of autumn later in the day as the sun sets on the closing of the unofficial last weekend of the summer season.

TODAY: Sun/cloud mix. Highs 71-78. Dew point 50s. Wind NE 5-15 MPH.

TONIGHT: Partly cloudy to mostly clear. Patchy ground fog interior valleys. Lows 51-58. Dew point lower 50s. Wind NE to variable under 10 MPH.

FRIDAY: Mostly sunny to partly cloudy. Highs 68-75. Dew 50s. Wind E up to 10 MPH.

FRIDAY NIGHT: Partly cloudy. Patchy ground fog. Lows 55-62. Dew point in 50s. Wind variable to SE under 10 MPH.

SATURDAY: Partly sunny. A shower possible mainly south of I-90 morning. Highs 75-82. Dew point rising to 60s. Wind S 5-15 MPH.

SATURDAY NIGHT: Variably cloudy. A possible shower in the evening. Showers and possible thunderstorms overnight. Patchy fog overnight. Lows 62-69. Dew point 60s. Wind SW 5-15 MPH.

SUNDAY: Lots of clouds with showers ending west to east in the morning. Sun/cloud mix thereafter. Highs 71-78. Dew point falls below 60. Wind W 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Lows 52-59. Dew point near 50. Wind W 5-15 MPH.

MONDAY (LABOR DAY): Sun and passing clouds. Highs 70-77. Dew point 50s. Wind W 5-15 MPH, higher gusts, shifting to NW.

DAYS 6-10 (SEPTEMBER 3-7)

High pressure will dominate with generally fair weather during much of next week. Temperatures start out near to below normal then moderate slightly.

DAYS 11-15 (SEPTEMBER 8-12)

Dry weather expected early in the period before unsettled weather becomes more likely mid period, then fair weather again late period. Temperatures near to slightly above normal.

DAYS 1-5 (AUGUST 28 – SEPTEMBER 1)

Today is going to be our warmest and most humid day of the next several, aided by the passage of a warm front early this morning with nothing more than a few spot sprinkles of rain which exited the North Shore of MA about 7:00 a.m. Between this front and the approach and passage of a cold front during from northwest to southeast during midday and this afternoon, we spike “heat” and humidity, and I quote the word heat because it’ll be relatively hot in comparison to many recent August days (Boston is running a small negative temperature departure for the month). While I few spots may make it to 90 – something we haven’t seen for quite some time – most high temps will be in the 80s today, along with dew points in the 60s, certainly not oppressive, but noticeably humid. Big thunderstorms with the front? Nope. The support is just not really there, and the timing is also a couple hours early to maximize what does exist, so I only expect a few isolated showers and possibly a heavier thunderstorm somewhere, and this will favor the I-90 belt southward in the mid afternoon hours where the front’s position and maximum heating coincide. Tonight, a cooler air mass arrives behind the front. Thursday and Friday will feature fair weather and lower than normal temperatures with a general northeasterly air flow, with high pressure stretching from Quebec to Atlantic Canada. Some coastal clouds may be somewhat abundant for several hours on Thursday, but for the most part I just expect a sun / cloud mix both days, with more sun Friday. Heading into the Labor Day Weekend, we’ll see a modest warm-up, but a cold front has to cross the region at some point, bringing a shower threat. My current thinking is the timing of this front will be late Saturday night and Sunday morning to cross the region, with the greatest shower threat from northwest to southeast occurring during the first 12 hours of Sunday’s calendar day (midnight to noon). I’ll watch shorter range guidance trends as we get closer and tweak these forecast details as needed.

TODAY: Sun/cloud mix. A passing brief shower or thunderstorm is possible midday to mid afternoon favoring the I-90 belt to the South Coast region. Highs 83-90. Dew point in the 60s. Wind SW 5-15 MPH, shifting to NW.

TONIGHT: Partly cloudy early, then clearing, but patchy ground fog possible, mainly over interior lower elevations. Lows 56-63. Dew point falls into and through the 50s. Wind N up to 10 MPH.

THURSDAY: Partly sunny – more clouds along the coast than inland. Highs 70-77. Dew point in the 50s. Wind NE 5-15 MPH.

THURSDAY NIGHT: Partly cloudy to mostly clear. Patchy ground fog interior lower elevation areas. Lows 51-58. Dew point lower 50s. Wind NE under 10 MPH.

FRIDAY: Mostly sunny to partly cloudy. Highs 68-75. Dew point in 50s. Wind E up to 10 MPH.

FRIDAY NIGHT: Partly cloudy. Patchy ground fog. Lows 55-62. Dew point in 50s. Wind variable to SE under 10 MPH.

SATURDAY: Partly sunny. A shower possible mainly far western areas late in the day. Highs 75-82. Dew point rising toward 60. Wind S 5-15 MPH.

SATURDAY NIGHT: Variably cloudy. Possible showers and a chance of thunderstorms mainly overnight. Patchy fog overnight. Lows 62-69. Dew point 60+. Wind SW 5-15 MPH.

DAYS 6-10 (SEPTEMBER 2-6)

A cold front is expected to cross the region on Labor Day, September 2, with a brief shower possible. Fair weather follows with near to below normal temperatures much of next week.

DAYS 11-15 (SEPTEMBER 7-11)

Dry weather may last into if not through the September 7-8 weekend with a warming trend before unsettled weather becomes more possible later in the period.

DAYS 1-5 (AUGUST 27-31)

This 5-day forecast period finds us closing out August and reaching the Labor Day Weekend (day 5). Yesterday’s weather was somewhat volatile as a potent disturbance triggered thunderstorms. Not every location saw them, but those that did were rocked pretty good with heavy rain, hail, frequent lightning, and a few strong wind gusts. But it’s much quieter this morning, with only some fog and low cloud patches around. Those will dissipate as the sun rises and we’re in for a nice day today with high pressure in control. Low pressure passes north of New England on Wednesday, sending a cold front through the region. This front brings the chance of passing showers and thunderstorms then leads a cooler, drier air mass into the region Thursday and Friday. The next front approaches on Saturday with a shower and thunderstorm chance returning, but timing is uncertain on this one, so check upcoming updates as we focus on the forecast for the holiday weekend.

TODAY: Low cloud / fog patches early, otherwise sun and a few clouds. Highs 76-83. Dew point near to a little under 60. Wind N up to 10 MPH shifting to E.

TONIGHT: Partly cloudy. Patchy fog. Lows 60-67. Dew point near 60. Wind variable under 10 MPH.

WEDNESDAY: Variably cloudy. Chance of showers and thunderstorms. Highs 81-88. Dew point 60+. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Variably cloudy. Chance of showers and thunderstorms in the evening. Patchy fog. Lows 56-63. Dew point around to below 60. Wind NW 5-15 MPH.

THURSDAY: Partly cloudy. Highs 70-77. Dew point sub-60. Wind N to NE 5-15 MPH.

THURSDAY NIGHT: Mostly clear. Lows 53-60. Dew point near 50. Wind NE under 10 MPH.

FRIDAY: Mostly sunny. Highs 68-75. Dew point in 50s. Wind NE up to 10 MPH.

FRIDAY NIGHT: Partly cloudy. Patchy ground fog. Lows 55-62. Dew point in 50s. Wind variable to SW up to 10 MPH.

SATURDAY: Partly sunny. A shower or thunderstorm possible. Highs 75-82. Wind SW 5-15 MPH.

DAYS 6-10 (SEPTEMBER 1-5)

We’ll have to watch for a shower chance early September 1 and late September 2 with passing fronts, otherwise the balance of the holiday weekend looks mainly rain-free and mild to warm. Fair, mild to warm weather continues mid period with a shower chance returning late period.

DAYS 11-15 (SEPTEMBER 6-10)

Unsettled weather most likely early in the period otherwise a quiet pattern with near to slightly above normal temperatures.

DAYS 1-5 (AUGUST 26-30)

There are two active weather days coming up in the next five days. Today is one of them, with a disturbance and cool pool dropping southward across New England with a warm and moderately humid air mass in place. This is a recipe for showers and thunderstorms to develop, and we’ll see them do so in scattered to clustered fashion starting by early afternoon, and peaking mid afternoon to early evening. While not everybody gets hit today, areas that do have the potential to experience a strong to severe storm with possible hail and strong wind gusts, as well as torrential downpours and a period of frequent lightning. If you have outdoor plans, or will be traveling, be alert to potentially rapidly changing weather conditions and storm-related hazards. This activity diminishes and moves away this evening as the sun sets and the disturbance exits. A weak area of high pressure builds in with fair and warm weather Tuesday. As this high pushes to the south, a cold front will drop into and through the region Wednesday, with another round of showers and thunderstorms likely initiated by this system. Timing of the boundary’s movement through the region will determine where and when storms fire, and how long they are around. Tweaks on this will take place over the next 2 updates. High pressure to our north brings drier, cooler weather Thursday and Friday.

TODAY: Variably cloudy. Potential showers and thunderstorms especially during afternoon and early evening hours. Thunderstorms can be severe. Highs 75-82. Dew point near 65. Wind variable up to 10 MPH but can be strong and gusty near any storms.

TONIGHT: Variably cloudy. Possible showers and thunderstorms early, especially south of I-90. Patchy fog. Lows 61-68. Dew point 60+. Wind W up to 10 MPH shifting to N.

TUESDAY: Partly cloudy. Highs 76-83. Dew point near to a little under 60. Wind N up to 10 MPH shifting to E.

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

WEDNESDAY: Variably cloudy. Chance of showers and thunderstorms. Highs 81-88. Dew point 60+. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Variably cloudy. Chance of showers and thunderstorms in the evening. Patchy fog. Lows 56-63. Dew point around to below 60. Wind NW 5-15 MPH.

THURSDAY: Partly cloudy. Highs 70-77. Dew point sub-60. Wind N to NE 5-15 MPH.

THURSDAY NIGHT: Mostly clear. Lows 53-60. Dew point near 50. Wind NE under 10 MPH.

FRIDAY: Mostly sunny. Highs 68-75. Dew point in 50s. Wind NE up to 10 MPH.

DAYS 6-10 (AUGUST 31 – SEPTEMBER 4)

Labor Day Weekend is August 31 through September 2, and the weather looks “mostly” good. One frontal system moves through between later August 31 and the first half of September 1 with a shower and thunderstorm potential, timing to be pinned down in the days ahead. Another front may approach with a shot of a shower or storm later on Labor Day. Fair and warm weather looks likely later in the period.

DAYS 11-15 (SEPTEMBER 5-9)

An unsettled interlude early to mid period in an otherwise fairly quiet pattern with near to slightly above normal temperatures.
