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.

SUNDAY: Partly sunny. A shower possible mainly far eastern areas early in the day. Highs 71-78. Dew point falls below 60. Wind W 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.

DAYS 1-5 (AUGUST 25-29)

High pressure hangs on with fair weather today and while a trough approaches from the north and west we will see more clouds later on. Shower activity is expected to remain north and west of the region though. But that changes in a small way tonight when one can wander down as the trough gets closer, and Monday we pop several showers and storms during the day, especially in the afternoon to early evening from north to south, as the low pressure trough passes by. I’ve shifted Tuesday to a drier forecast with a sliver of high pressure in control. Earlier I had pop up showers possible here but that does not look to be the case now. It is Wednesday when the shower and thunderstorm chance returns as we get a shot of warmer air and a frontal boundary approaches. Another high pressure area builds in Thursday with fair weather returning.

TODAY: Lots of sun much of the time, more clouds and less sun later on. Highs 80-87. Dew point near 60. Wind SW up to 10 MPH.

TONIGHT: Variably cloudy. A possible shower overnight. Patchy fog. Lows 61-68. Dew point 60+. Wind S up to 10 MPH.

MONDAY: Variably cloudy. Potential showers and thunderstorms especially during the mid to late afternoon and evening hours. Highs 75-82. Dew point near 65. Wind S 5-15 MPH shifting to W.

MONDAY NIGHT: 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 71-78. 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 80-87. 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. Wind N up to 10 MPH shifting to E.

DAYS 6-10 (AUGUST 30 – SEPTEMBER 3)

Labor Day Weekend is August 31 through September 2, and this 5-day period covers anybody extending it a day (or 2) on either side. Pattern looks generally dry but a frontal boundary may be crossing the region to start the period with a shower threat, delivering a pleasant air mass to start the weekend, followed by a trend to warmer and slightly more humid weather.

DAYS 11-15 (SEPTEMBER 4-8)

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

DAYS 1-5 (AUGUST 24-28)

High pressure will provide generally fair weather through the weekend. A weak mid level disturbance will move by later today and tonight with a few more clouds, and another trough will approach later Sunday with an increase in clouds, but I expect any showers that pop up on Sunday afternoon will remain to the west and north of the WHW forecast area. Monday’s weather will be unsettled as a low pressure trough moves through, triggering scattered showers and thunderstorms, especially during the later afternoon and evening hours. When we get to Tuesday and Wednesday, the medium range guidance shows a spread of potential solutions with various weather outcomes ranging from fair to showery. Currently, my thought is that a weak upper low will hang around the region with a pop up shower possible either day, and air temperature will be dictated by surface air flow, which looks mostly regionally onshore Tuesday and more offshore Wednesday, making Tuesday the cooler day and Wednesday a warmer one. But at days 4 and 5 and with such a spread across guidance, the forecast that follows is lower than average confidence and I’ll fine-tune this section of it in the next couple of blog posts…

TODAY: Sunny morning. Partly cloudy afternoon. Highs 79-86. Dew point near 55. Wind variable to W up to 10 MPH.

TONIGHT: Partly cloudy. Lows 57-65. Dew point near 55. Wind SW under 10 MPH.

SUNDAY: Sun/cloud mix with a tendency for more clouds later in the day. Highs 80-87. Dew point near 60. Wind SW up to 10 MPH.

SUNDAY NIGHT: Variably cloudy. A possible shower overnight. Patchy fog. Lows 61-68. Dew point 60+. Wind S up to 10 MPH.

MONDAY: Variably cloudy. Potential showers and thunderstorms especially during the mid to late afternoon and evening hours. Highs 75-82. Dew point near 65. Wind S 5-15 MPH shifting to W.

MONDAY NIGHT: Variably cloudy. Possible showers and thunderstorms early. Patchy fog. Lows 61-68. Dew point 60+. Wind W up to 10 MPH shifting to N.

TUESDAY: Partly sunny. Chance of a shower. Highs 73-80. Dew point near 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: Partly sunny. Slight chance of a shower. Highs 80-87. Dew point near 60. Wind variable to W up to 10 MPH.

DAYS 6-10 (AUGUST 29 – SEPTEMBER 2)

Fairly quiet pattern overall but a passing frontal system later August 30 or early August 31 can produce a shower threat, and an approaching frontal system may do the same at the end of the period. Labor Day Weekend is August 31 through September 2. No significant temperature extremes.

DAYS 11-15 (SEPTEMBER 3-7)

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

DAYS 1-5 (AUGUST 23-27)

High pressure builds in and brings us a stretch of fair weather through the weekend with a gradual warm up and increase in humidity taking place. There will be some diurnal cloud development each day today and Saturday, with more on Saturday than today. Clouds will also start to increase later on Sunday as a trough of low pressure approaches from the west. This trough will combine with higher humidity to bring a shower and thunderstorm chance Monday, which lingers as well into Tuesday, with a slight cooling trend early next week.

TODAY: Mostly sunny. Highs 73-80. Dew point lower 50s. Wind W 5-15 MPH.

TONIGHT: Clear. Fog patches interior lower elevations. Lows 55-62. Dew point lower 50s. Wind W to SW up to 10 MPH.

SATURDAY: Partly sunny. Highs 79-86. Dew point middle 50s. Wind W to SW 5-15 MPH.

SATURDAY NIGHT: Mostly clear. Lows 57-64. Dew point middle 50s.

SUNDAY: Sunny morning. Partly cloudy afternoon. Highs 80-87. Dew point breaks 60. Wind SW 5-15 MPH.

SUNDAY NIGHT: Variably cloudy. A possible shower overnight. Patchy fog. Lows 61-68. Dew point 60+. Wind S up to 10 MPH.

MONDAY: Variably cloudy. Potential showers and thunderstorms. Highs 75-82. Dew point 60+. Wind S 5-15 MPH shifting to W.

MONDAY NIGHT: Variably cloudy. Possible showers and thunderstorms early. Patchy fog. Lows 61-68. Dew point 60+. Wind W up to 10 MPH shifting to N.

TUESDAY: Partly sunny. Chance of showers. Highs 73-80. Dew point near 60. Wind N up to 10 MPH shifting to E.

DAYS 6-10 (AUGUST 28 – SEPTEMBER 1)

High pressure brings fair weather much of the time during the final days of August and into the Labor Day Weekend but watch for a passing front and shower threat about August 30. Temperatures briefly cooler, then warming back up again.

DAYS 11-15 (SEPTEMBER 2-6)

Watch for a couple frontal boundaries to bring shower chances around Labor Day and later in the period. Temperatures near to slightly above normal.

DAYS 1-5 (AUGUST 22-26)

An upper level trough and cool pool remain nearby today, but will be starting to lift away from the region while weakening. There’s still enough influence from it to develop diurnal cumulus clouds, and a few of these can build enough to produce isolated showers, mainly north of Interstate 90 during this afternoon. For the most part and in most areas, it’ll be a rain-free, coolish late August day. High pressure builds in Friday and hangs around just to the south through the weekend, providing fair weather and a warming trend, with abundant sunshine Friday, Saturday, and most of Sunday. More clouds may arrive later Sunday in advance of the next approaching disturbance. This will be a trough of low pressure that moves into the region from the northwest Sunday and Monday, triggering the chance of showers and thunderstorms on Monday, and putting an end to the warm up as well.

TODAY: Sunny start, then a sun/cloud mix. A pop-up shower possible mainly north of I-90 this afternoon. Highs 70-77. Dew point near 50. Wind variable up to 10 MPH with coastal sea breeze possible.

TONIGHT: Partly cloudy. Patchy ground fog inland lower elevations. Lows 48-55, coolest inland lower elevations. Dew point upper 40s to 50. Wind variable under 10 MPH.

FRIDAY: Mostly sunny. Highs 73-80. Dew point lower 50s. Wind W 5-15 MPH.

FRIDAY NIGHT: Clear. Fog patches interior lower elevations. Lows 55-62. Dew point lower 50s. Wind W to SW up to 10 MPH.

SATURDAY: Sunny. Highs 79-86. Dew point middle 50s. Wind W to SW 5-15 MPH.

SATURDAY NIGHT: Clear. Lows 57-64. Dew point middle 50s.

SUNDAY: Sunny morning. Partly cloudy afternoon. Highs 80-87. Dew point near 60. Wind SW 5-15 MPH.

SUNDAY NIGHT: Variably cloudy. A possible shower overnight. Lows 61-68. Dew point near 60. Wind W 5-15 MPH.

MONDAY: Variably cloudy. Potential showers and thunderstorms. Highs 75-82. Dew point 60+. Wind W 5-15 MPH shifting to N.

DAYS 6-10 (AUGUST 27-31)

Upper level low pressure may produce a pop-up shower during August 27. High pressure brings fair weather much of the time during the final days of August but watch for a passing front and shower threat about August 30. Temperatures briefly cooler, then warming back up again.

DAYS 11-15 (SEPTEMBER 1-5)

Overall pattern looks quiet – minor disturbances / frontal passages bring short-lived shower chances around Labor Day and later in the period. Temperatures near to slightly above normal.

DAYS 1-5 (AUGUST 21-25)

Upper level low pressure will hang around today then start to lift out on Thursday. This cool pool of air aloft, combined with solar heating each day, will aid in the development of clouds. These clouds can produce a few scattered showers and even thunderstorms, with the latter while still a low probability being more possible today than tomorrow. Any pop up showers or storms can produce small hail today with the magnitude of cold air aloft. Activity tomorrow should be more isolated and mainly north of Mass Pike. High pressure will bring fair weather and a warming trend Friday-Sunday. Humidity remains very low into the weekend before nudging up by Sunday.

TODAY: Sunny start, then a sun/cloud mix. Isolated to scattered showers and a slight chance of thunderstorms mainly between 1:00 p.m. and 6:00 p.m.. Showers/storms can produce briefly gusty wind and small hail. Highs 68-75. Dew point around 50. Wind NW to W up to 10 MPH.

TONIGHT: Clearing. Patchy ground fog interior lower elevation locations. Lows 50-57. Dew point near 50. Wind variable under 10 MPH.

THURSDAY: Partly sunny. A pop-up shower possible mainly north of I-90 during the afternoon. Highs 70-77. Dew point near 50. Wind variable up to 10 MPH with coastal sea breeze possible.

THURSDAY NIGHT: Partly cloudy. Patchy ground fog inland lower elevations. Lows 48-55, coolest inland lower elevations. Dew point upper 40s to 50. Wind variable under 10 MPH.

FRIDAY: Mostly sunny. Highs 73-80. Dew point lower 50s. Wind W 5-15 MPH.

FRIDAY NIGHT: Clear. Fog patches interior lower elevations. Lows 55-62. Dew point lower 50s. Wind W to SW up to 10 MPH.

SATURDAY: Sunny. Highs 79-86. Dew point middle 50s. Wind W to SW 5-15 MPH.

SATURDAY NIGHT: Clear. Lows 57-64. Dew point middle 50s.

SUNDAY: Sunny. Highs 80-87. Dew point near 60. Wind SW 5-15 MPH.

DAYS 6-10 (AUGUST 26-30)

A disturbance brings a shower and thunderstorm opportunity August 26. Upper level low pressure may produce a pop-up shower during August 27. Generally fair weather is expected after that until the very end of the period when an approaching trough / front brings a shower / t-storm opportunity. Temperatures briefly cooler, then warming back up again.

DAYS 11-15 (AUGUST 31 – SEPTEMBER 4)

Early hints on Labor Day Weekend are for fair and seasonably warm weather which may then carry through the period with high pressure to the south and weak weather systems passing mainly to the north of New England.

DAYS 1-5 (AUGUST 20-24)

The beginning of the day catches the transition from one air mass to another in progress, with dew points still near 70 over Cape Cod but in the 50s in north central MA and southwestern NH. Between them is a cold front, about to slide offshore via the South Shore & South Coast. One more quick round of showers will visit RI and southeastern MA this morning under a canopy of clouds associated with the front, and then we’ll enjoy a day of mixed sun and clouds with lower dew points and cooler air. Comfortably low humidity continues through mid week along with below normal temperatures as upper level low pressure crosses the region. This feature will be responsible for the development of clouds each day Wednesday and Thursday. Scattered showers and even a few thunderstorms can and likely will pop up Wednesday, a few potentially producing small hail due to the cold air aloft. Thursday’s activity should be limited to more isolated showers favoring areas north of I-90. This low departs by Friday and high pressure builds in with fair weather that lasts into the weekend, including a warming trend.

TODAY: Lots of clouds through mid morning including areas of fog South Coast and a round of showers moving through RI and southeastern MA. Cloud/sun mix thereafter. Highs 68-75. Dew point starts out ranging from the 50s north central MA and southwestern NH to near 70 southeastern MA, but drops to the 50s all areas. Wind N to NW 5-15 MPH.

TONIGHT: Partly cloudy. Patchy fog interior lower elevations. Lows 51-58. Dew point lower 50s. Wind N up to 10 MPH.

WEDNESDAY: Most sun in the morning, more clouds midday and afternoon when a passing shower or thunderstorm is possible. Highs 68-75. Dew point around 50. Wind N up to 10 MPH but can be gusty around any showers and storms.

WEDNESDAY NIGHT: Partly cloudy. Patchy fog interior lower elevations. Lows 50-57. Dew point upper 40s to 50. Wind variable under 10 MPH.

THURSDAY: Partly sunny. A pop-up shower possible mainly north of I-90 during the afternoon. Highs 70-77. Dew point near 50. Wind variable up to 10 MPH with coastal sea breeze possible.

THURSDAY NIGHT: Partly cloudy. Patchy ground fog inland lower elevations. Lows 48-55, coolest inland lower elevations. Dew point sub-50. Wind variable under 10 MPH.

FRIDAY: Mostly sunny. Highs 73-80. Dew point in 50s. Wind W 5-15 MPH.

FRIDAY NIGHT: Clear. Fog patches interior lower elevations. Lows 55-62. Dew point in 50s. Wind W to SW up to 10 MPH.

SATURDAY: Sunny. Highs 80-87. Dew point in 50s. Wind W to SW 5-15 MPH.

DAYS 6-10 (AUGUST 25-29)

Overall pattern looks fairly rain-free with more typical late summer warmth. One disturbance around August 26 or 27 can produce a shower or thunderstorm threat otherwise high pressure controls the weather most of the time.

DAYS 11-15 (AUGUST 30 – SEPTEMBER 3)

Limited wet weather chances / mainly dry weather with high pressure mostly in control. Higher humidity potential for mid to late period. Early call on Labor Day Weekend (August 31 – September 2) looks mainly fair.

DAYS 1-5 (AUGUST 19-23)

A low pressure trough and associated cold front will move slowly across the region today through early Tuesday with unsettled weather in the form of occasional showers. There can be a few thunderstorms involved as well until the front pushes through the region from west to east this evening. Upper level low pressure will hang around through midweek. A dry slot brings any showers to an end after early Tuesday, but pop-up afternoon showers are possible both Wednesday and Thursday with the help of solar heating. Temperatures will run below normal through mid week, with some “feel of fall” nights upcoming once we get rid of the current humid air mass. By Friday, high pressure builds in with fair weather, a cool start, and a warmer afternoon. Ernesto re-strengthened to a hurricane north northeast of Bermuda yesterday and will continue to accelerate into the open North Atlantic through midweek, still producing some rough surf and large ocean swells along our coast for a couple more days before that subsides.

TODAY: Cloudy with areas of fog this morning including periodic showers and the chance of a thunderstorm. Mostly cloudy but breaks of sun this afternoon with a chance of a passing shower, then a better shower and thunderstorm chance returning in the early evening from west to east. Highs 74-81. Dew point 65+. Wind SE to S up to 10 MPH.

TONIGHT: Mostly cloudy. Scattered showers. Patchy fog. Lows 60-67. Dew point 60+. Wind S to SW up to 10 MPH.

TUESDAY: Mostly cloudy through mid morning with patchy fog and passing showers. Partial sun by midday on. Highs 68-75. Dew point near 60, lowering into 50s. Wind shifting to N 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. Patchy fog interior lower elevations. Lows 51-58. Dew point lower 50s. Wind N up to 10 MPH.

WEDNESDAY: Partly sunny. A pop-up shower possible. Highs 68-75. Dew point lower 50s. Wind N up to 10 MPH.

WEDNESDAY NIGHT: Partly cloudy. Patchy fog interior lower elevations. Lows 50-57. Dew point upper 40s to 50. Wind variable under 10 MPH.

THURSDAY: Partly sunny. A pop-up shower possible. Highs 70-77. Dew point near 50. Wind variable up to 10 MPH with coastal sea breeze possible.

THURSDAY NIGHT: Partly cloudy. Patchy ground fog inland lower elevations. Lows 48-55, coolest inland lower elevations. Dew point sub-50. Wind variable under 10 MPH.

FRIDAY: Mostly sunny. Highs 73-80. Dew point in 50s. Wind W 5-15 MPH.

DAYS 6-10 (AUGUST 24-28)

High pressure is expected to provide fair weather with a warming trend over the August 24-25 weekend. Higher humidity and shower / t-storm chances return thereafter as a trough and frontal system move into the region.

DAYS 11-15 (AUGUST 29 – SEPTEMBER 2)

High pressure returns with drier and mild weather to finish the month of August then a warm-up and more humid weather heading toward Labor Day (September 2).

DAYS 1-5 (AUGUST 18-22)

Despite an early visit from showers for most of the area (not really in the forecast), we still have a majority rain-free day ahead as showers become less numerous then depart the region as the morning goes along, and only a few quick showers remain possible mainly west of I-95 during the afternoon. This unsettled weather and the episodes of showers Monday and early Tuesday will be caused by a trough of low pressure moving through from west to east, as weather systems are finally back on the move again. Behind this comes cooler and drier air for the middle of next week, but with an upper trough of low pressure still hanging around, I can’t rule out a few pop-up showers both Wednesday and Thursday with the help of daytime heating.

TODAY: An overcast start with fairly widespread showers and areas of fog. Clouds break for sun at times thereafter but a passing shower can occur late morning on favoring areas west of I-95. Highs 74-81, warmest inland areas. Dew point 65+. Wind SE up to 10 MPH.

TONIGHT: Mostly cloudy. Scattered showers. Patchy fog. Lows 65-72. Dew point 65+. Wind S up to 10 MPH.

MONDAY: Variably cloudy. Occasional showers and a chance of thunderstorms greatest chance morning and again late afternoon / early evening. Highs 72-79. Dew point 65+. Wind S to variable 5-15 MPH.

MONDAY NIGHT: Mostly cloudy. A few showers possible. Patchy fog. Lows 62-69. Dew point 60+. Wind variable up to 10 MPH.

TUESDAY: Mostly cloudy with a chance of showers and drizzle along with areas of fog in the morning. Clouds break for sun during the afternoon. Highs 69-76. Dew point 60+, falling to 50s. Wind NE to N 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. Patchy fog interior lower elevations. Lows 56-63. Dew point lower to middle 50s. Wind N up to 10 MPH.

WEDNESDAY: Partly sunny. A pop-up shower possible. Highs 68-75. Dew point in 50s. Wind N up to 10 MPH.

WEDNESDAY NIGHT: Partly cloudy. Patchy fog interior lower elevations. Lows 56-63. Dew point lower to middle 50s. Wind variable under 10 MPH.

THURSDAY: Partly sunny. A pop-up shower possible. Highs 70-77. Dew point in 50s. Wind variable up to 10 MPH with coastal sea breeze possible.

DAYS 6-10 (AUGUST 23-27)

High pressure is expected to provide fair weather with a warming trend heading into late next week. Humidity starts low then climbs slowly. Showers may become possible later in the period.

DAYS 11-15 (AUGUST 28 – SEPTEMBER 1)

A fairly seasonable pattern of moderate humidity and a few shower and thunderstorm opportunities, but no sustained major heat to end August and greet September, driven by a moderate westerly air flow across the Northeast.

DAYS 1-5 (AUGUST 17-21)

Hurricane Ernesto crossed Bermuda this morning and is now set to accelerate away from there and into the open North Atlantic this weekend, well southeast to of New England. As previously noted, Ernesto’s impact on our region come in a couple forms. One is to increase ocean swells and rough surf especially later in the weekend into the beginning of next week. The other is to delay the arrival of a trough from the west, keeping most of our weekend rain-free. We are still contending with a significant plume of high altitude wildfire smoke from Canada, which has been directed southward across our sky for the past several days due to the lack of upper pattern feature movement, but this plume will thin from west to east during the course of the weekend, just in time for more clouds to arrive from the west. However, as noted, shower activity will be limited to just light and scattered on Sunday, with the main activity from the trough coming through this region in a couple surges between early Monday and midday Tuesday as a frontal system and wave or two of low pressure impact southeastern New England. Drier air arrives later Tuesday and Wednesday, along with below normal temperatures and low humidity.

TODAY: Lots of clouds / limited smoke-filtered sun. Highs 75-82, warmest inland. Dew point 60+. Wind variable to SE up to 10 MPH.

TONIGHT: Mostly cloudy. Areas of fog. Lows 62-69, warmest in urban locations. Dew point 60+. Wind SE to S under 10 MPH.

SUNDAY: Clouds dominate but intervals of sun and a possible passing shower, mainly west of I-95. Highs 76-83, warmest inland. Dew point 65+. Wind SE to S up to 10 MPH.

SUNDAY NIGHT: Mostly cloudy. Scattered showers. Patchy fog. Lows 65-72. Dew point 65+. Wind S up to 10 MPH.

MONDAY: Variably cloudy. Occasional showers and a chance of thunderstorms. Highs 72-79. Dew point 65+. Wind S to variable 5-15 MPH.

MONDAY NIGHT: Mostly cloudy. Periodic showers. Chance of thunderstorm. Patchy fog. Lows 62-69. Dew point 60+. Wind variable up to 10 MPH.

TUESDAY: Mostly cloudy with a chance of showers and drizzle along with areas of fog in the morning. Clouds break for sun during the afternoon. Highs 69-76. Dew point 60+, falling to 50s. Wind NE to N 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. Patchy fog. Lows 56-63. Dew point lower to middle 50s. Wind N up to 10 MPH.

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

DAYS 6-10 (AUGUST 22-26)

High pressure maintains fair weather and low humidity from the middle of next week at least into the August 24-25 weekend before higher humidity and shower/thunderstorm chances arrive late in the period.

DAYS 11-15 (AUGUST 27-31)

A fairly seasonable pattern of moderate humidity and a few shower and thunderstorm opportunities, but no sustained major heat to end August, driven by a moderate westerly air flow across the Northeast.
