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.

DAYS 1-5 (AUGUST 16-20)

The upper low that brought some shower and thunderstorm activity yesterday, including a few instances of severe weather (hail, wind damage), moves away today and an area of high pressure moves in with fair weather. But that fair weather does not mean a deep blue sunny sky all day long. Low level moisture has triggered stratus and fog that much of the region will see to start the day, and once that dissipates we have a veil of high altitude wildfire smoke to filter the sun, which will also be mixed with clouds. Our weekend will feature a continuation of wildfire smoke in the sky through Saturday, and probably Sunday too though we’ll see less of it then due to an increase in cloud cover underneath the main smoke layer. Hurricane Ernesto, which is forecast to make a close pass to Bermuda Saturday before accelerating northeastward over the open western Atlantic, will play a role in our weather, but it’s actually a positive one. This system is part of a pattern that holds up the eastward movement of weather systems, and the trough we’ve been watching for a weekend arrival via the Midwest / Great Lakes is going to be slow enough that we get through most of the weekend rain-free, with the shower threat holding off until later Sunday. One other impact from Ernesto will be increasing ocean swells along the coast during the course of the weekend, and into early next week. As for our early week weather here, the trough from the west finally gets in to bring us unsettled weather Monday and probably into if not through Tuesday, depending on how quickly things start to move eastward again. Tuesday’s forecast may change for the better if things move more quickly…

TODAY: Low clouds and areas of fog to start, then smoke-filtered sun mixed with clouds. Highs 77-84. Dew point 60+. Wind variable up to 10 MPH.

TONIGHT: Partly cloudy. High altitude smoke. Patchy fog. Lows 61-68. Dew point 60+. Wind S under 10 MPH.

SATURDAY: Partly sunny. High altitude smoke. Highs 79-86, coolest South Coast. Dew point in 60s. Wind S 5-15 MPH.

SATURDAY NIGHT: Variably cloudy. Patchy fog. Lows 63-70, warmest urban areas. Dew point in 60s. Wind S up to 10 MPH.

SUNDAY: Mostly cloudy. A chance of showers late in the day, favoring areas west of I-95. Highs 78-85. Dew point in 60s. Wind S 5-15 MPH.

SUNDAY NIGHT / MONDAY: Variably cloudy. Occasional showers and a chance of thunderstorms. Patchy fog. Lows 64-71. Highs 72-79. Dew point middle 60s to lower 70s. Wind S to variable 5-15 MPH.

MONDAY NIGHT / TUESDAY: Mostly cloudy. Occasional showers. Patchy fog. Lows 62-69. Highs 70-77. Dew point 60+. Wind variable to NE 5-15 MPH.

DAYS 6-10 (AUGUST 21-25)

A stretch of dry and pleasant weather is expected for much of next week with high pressure in control and a flow of air out of Canada / Great Lakes.

DAYS 11-15 (AUGUST 26-30)

A return of higher humidity and a few shower chances as a more typical August pattern returns for the late days of the month.

DAYS 1-5 (AUGUST 15-19)

Upper level low pressure spinning off to our east will do a few things to our weather over the next few days. Firstly, it drives additional wildfire smoke southward out of Canada through at least Friday. It triggers some showers that visit parts (or most) of our region later today and this evening, and it slows down the approach of the next trough that we end up with the majority of the upcoming weekend rain-free. Ernesto is forecast to make a north to northeast track over the western Atlantic in the coming days, peaking as a category 3 hurricane southwest of Bermuda before starting a slow weakening trend and passing close to the island on Saturday. Eventually Ernesto starts to pick up speed and track north northeast, passing far east of New England. It will generate large ocean swells and rough surf heading through the weekend and early next week. Back here in New England, as we get to the start of next week we’ll see a better shot of showers and thunderstorms on Monday as a trough moves into the region.

TODAY: Filtered sun mixed with clouds then clouds taking over later on and showers more likely from north to south late day into the evening. Highs 77-84. Dew point lower 60s. Wind variable to N up to 10 MPH, but can be a little stronger around any showers.

TONIGHT: Variably cloudy. A chance of showers in the evening. Patchy fog forming. Lows 58-65. Dew point upper 50s to lower 60s. Wind variable under 10 MPH.

FRIDAY: Partly sunny. Highs 77-84. Dew point near 60. Wind variable up to 10 MPH.

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

SATURDAY: Partly sunny. Highs 78-85. Dew point 60+. Wind S 5-15 MPH.

SATURDAY NIGHT: Mostly cloudy. Patchy fog. Lows 60-67. Dew point 60+. Wind S up to 10 MPH.

SUNDAY: Variably cloudy. A chance of showers and thunderstorms in the afternoon. Highs 75-82. Dew point in 60s. Wind S 5-15 MPH.

SUNDAY NIGHT / MONDAY: Variably cloudy. Occasional showers and a chance of thunderstorms. Patchy fog. Lows 63-70. Highs 72-79. Dew point in 60s to near 70. Wind S to variable 5-15 MPH.

DAYS 6-10 (AUGUST 20-24)

Shower and thunderstorm chance early in the period followed by drier weather. Temperatures generally near normal – no major heat anticipated.

DAYS 11-15 (AUGUST 25-29)

A fairly quiet pattern expected late month with no prolonged major heat and limited shower and thunderstorm chances.

DAYS 1-5 (AUGUST 14-18)

Not much to update today. Upper low pressure to our east, high pressure to our west is the general pattern through Friday. The influence of solar heating and cool air aloft associated with the upper low can trigger isolated showers later today, but most areas will remain dry. Thursday, showers are again a potential, but a higher one, with greater coverage, and we’ll see those moving from north to south into the region during the second half of the afternoon into the evening. Friday will be a dry day. The slower movement of large scale systems now pretty much guarantees a rain-free Saturday as we’ll have a narrow area of high pressure between the departed upper low and the next trough approaching from the west. However, Sunday is more likely to be unsettled with clouds and showers as that trough from the west gets in. Other things of note include high altitude wildfire smoke from Canada in our sky much of the next three days, and it may be thickest on Thursday before starting to thin out by later on Friday. Additionally, forecast Hurricane Ernesto is expected to be well offshore of the US East Coast by this weekend, still far to the southeast of New England, but close enough that we’ll start seeing larger ocean swells along our coast.

TODAY: High altitude smoke with filtered sun. Becoming partly cloudy later with isolated late-day showers favoring areas west of I-95 / north of I-90. Highs 75-82. Dew point upper 50s to lower 60s. Wind variable up to 10 MPH with coastal sea breezes.

TONIGHT: Partly cloudy. A few isolated showers possible southern NH and northern MA in the evening. Fog patches develop interior lower elevations overnight. Lows 57-64. Dew point upper 50s. Wind variable up to 10 MPH.

THURSDAY: Filtered sun mixed with clouds with clouds taking over later on and showers more likely from north to south late day into the evening. Highs 77-84. Dew point lower 60s. Wind variable up to 10 MPH.

THURSDAY NIGHT: Variably cloudy. A chance of showers in the evening. Patchy fog forming. Lows 58-65. Dew point upper 50s to lower 60s. Wind variable under 10 MPH.

FRIDAY: Partly sunny. Highs 77-84. Dew point near 60. Wind variable up to 10 MPH.

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

SATURDAY: Partly sunny. Highs 78-85. Dew point 60+. Wind S 5-15 MPH.

SATURDAY NIGHT: Mostly cloudy. Patchy fog. Lows 60-67. Dew point 60+. Wind S up to 10 MPH.

SUNDAY: Mostly cloudy. Showers likely. Chance of a thunderstorm. Highs 73-80. Dew point in 60s. Wind S 5-15 MPH.

DAYS 6-10 (AUGUST 19-23)

A trough nearby means higher humidity and shower opportunities early next week before drier air arrives mid to late week. Ernesto well offshore early in the period will create large ocean swells and rough surf at the coast. Temperatures near normal.

DAYS 11-15 (AUGUST 24-28)

The late August pattern looks fairly benign – seasonably warm – a couple shower and thunderstorm chances to sort out as we get closer.

DAYS 1-5 (AUGUST 13-17)

The pattern through midweek features a little more upper low to our east and high pressure to our west. There are no major changes to the forecast with dry weather most of the time. The shower threat is still there for Thursday, but also have to allow for possible pop-up showers to our north Wednesday wandering into the northern portion of the WHW forecast area in isolated form. When we get to the weekend we’ll start to see a more southwesterly air flow evolving along with an increase in humidity levels. This may lead to a few showers later Saturday but for now keeping the forecast generally dry with any shower activity limited and mainly west.

TODAY: Sunny morning. Partly cloudy afternoon. Highs 76-83. Dew point in 50s. Wind NW up to 10 MPH but coastal sea breeze are possible midday on.

TONIGHT: Mostly clear. Shallow fog patches interior lower elevations. Lows 56-63. Dew point lower to middle 50s. Wind NW under 10 MPH.

WEDNESDAY: Mostly sunny to partly cloudy. Highs 75-82. Dew point rising to upper 50s. Wind variable up to 10 MPH with coastal sea breezes.

WEDNESDAY NIGHT: Partly cloudy. A few isolated showers possible southern NH and northern MA in the evening. Fog patches develop interior lower elevations overnight. Lows 57-64. Dew point middle to upper 50s. Wind variable up to 10 MPH.

THURSDAY: Partly sunny. Isolated to scattered afternoon showers possible. Highs 77-84. Dew point rising to lower 60s. Wind variable up to 10 MPH.

THURSDAY NIGHT: Partly cloudy. Isolated showers possible in the evening. Patchy ground fog. Lows 58-65. Dew point upper 50s to lower 60s. Wind variable under 10 MPH.

FRIDAY: Partly sunny. Highs 77-84. Dew point near 60. Wind variable up to 10 MPH.

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

SATURDAY: Partly sunny. Isolated afternoon showers possible mainly central MA to southwestern NH. Highs 78-85. Dew point 60+. Wind S 5-15 MPH.

DAYS 6-10 (AUGUST 18-22)

The approach / arrival of a trough from the west brings higher humidity and greater shower chances to finish off the weekend on August 18. Shower/thunderstorm chances early next week diminishing midweek as the trough exits and high pressure build back toward the region from the west. Forecast Hurricane Earnesto is expected to be passing well east of the East Coast on a north to northeastward trek early in the period with large ocean swells impacting coastal areas.

DAYS 11-15 (AUGUST 23-27)

Heading through late month the pattern looks fairly quiet, seasonably warm, with a couple passing disturbances providing short-lived unsettled weather chances. No indications of prolonged significant hot weather.

DAYS 1-5 (AUGUST 12-16)

The large scale pattern this week will feature a westerly flow, around a broad trough, with a bit of cyclonic curvature to the air flow in the region. This will take 2 disturbances across the region when we have shower chances – one this afternoon and early evening, another late-day Thursday. Today’s threat features some cold enough air aloft that isolated thunder and small hail are small chances with a few of the showers that do develop. Additionally, late-day timing means a few rainbows can be spotted if you’re in the right place at the right time! Otherwise, it’s a fair and nice week with the absence of heat and high humidity. One additional note: Tonight / early Tuesday is the last of the 3 “best nights” to view the Perseid meteor shower, and the sky should clear out behind today’s disturbance by late evening to provide good viewing conditions. Best opportunity you can give yourself is to get away from city lights, after 10 p.m. until shortly before daybreak.

TODAY: Sunny morning. Partly sunny afternoon with late afternoon to early evening isolated to scattered showers and a slight chance of thunderstorms. Any heavier showers or storms could produce small hail. Highs 76-83. Dew point in 50s. Wind W 5-15 MPH.

TONIGHT: Clearing. Lows 57-64. Dew point in 50s. Wind WNW up to 10 MPH.

TUESDAY: Sunny morning. Partly cloudy afternoon. Highs 76-83. Dew point in 50s. Wind NW up to 10 MPH.

TUESDAY NIGHT: Mostly clear. Shallow fog patches interior lower elevations. Lows 56-63. Dew point lower to middle 50s. Wind NW under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 75-82. Dew point rising to upper 50s. Wind variable up to 10 MPH with coastal sea breezes.

WEDNESDAY NIGHT: Mostly clear. Shallow fog patches interior lower elevations. Lows 57-64. Dew point middle to upper 50s. Wind variable up to 10 MPH.

THURSDAY: Partly sunny. Isolated to scattered afternoon showers possible. Highs 77-84. Dew point rising to lower 60s. Wind variable up to 10 MPH.

THURSDAY NIGHT: Partly cloudy. Patchy ground fog. Lows 58-65. Dew point upper 50s to lower 60s. Wind variable under 10 MPH.

FRIDAY: Partly sunny. Highs 77-84. Dew point near 60. Wind variable up to 10 MPH.

DAYS 6-10 (AUGUST 17-21)

The weekend will feature higher but not oppressive humidity and as a trough and frontal system approach from the west we’ll look for an increase in the shower chance, but right now timing favors Sunday 8/18 over Saturday 8/17, which should stay rain-free. Higher humidity and a few shower / t-storm chances may carry into early next week. At the same time we should be monitoring an offshore tropical system, possibly a hurricane, but strongest indications right now are that system would be well offshore.

DAYS 11-15 (AUGUST 22-26)

Heading into late month the pattern looks fairly quiet, seasonably warm, with a couple passing disturbances providing short-lived unsettled weather chances. No indications of prolonged significant hot weather.

DAYS 1-5 (AUGUST 11-15)

A quiet pattern is in place regarding our weather here well into the coming week, with high pressure in control most of the time. Daily wind direction will be largely determined by high pressure center positioning. The only potential interruptions to completely dry weather are isolated shower chances Monday from a trough passing by and Thursday from a very weak disturbance between 2 high pressure areas. As far as the visibility for Perseid Meteor Shower viewing, it looks great tonight and tomorrow night, though there may be a few clouds from time to time. We won’t have the moon around after midnight, which is when you can see up to 50+ meteors per hour in ideal viewing locations – that is, minimal light pollution. Good luck if you plan to be out there!

TODAY: Sunny morning. Sun/cloud mix afternoon. Some high altitude smoke mainly South Coast this morning. Highs 76-83. Dew point sub-60. Wind W 5-15 MPH.

TONIGHT: Mostly clear. Interior lower elevation fog patches. Lows 57-64. Dew point sub-60. Wind W under 10 MPH.

MONDAY: Partly sunny. A possible shower or thunderstorm in the afternoon. Low risk of small hail in any heavier showers. Highs 77-84. Dew point near 60. Wind W 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Lows 58-65. Dew point under 60. Wind W 5-15 MPH.

TUESDAY: Mostly sunny. Highs 76-83. Dew point in 50s. Wind NW 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Lows 56-63. Dew lower to middle 50s. Wind W up to 10 MPH.

WEDNESDAY: Mostly sunny. Highs 75-82. Dew point in 50s. Wind variable up to 10 MPH with coastal sea breezes.

WEDNESDAY NIGHT: Mostly clear. Lows 56-63. Dew point lower to middle 50s. Wind variable up to 10 MPH.

THURSDAY: Partly cloudy. A slight chance of an isolated shower. Highs 76-83, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (AUGUST 16-20)

There is disagreement in medium range guidance on all kinds of things, from the movement and timing of a trough approaching from the west next weekend to the potential track of an offshore tropical system that looks like it will develop and move into the Caribbean during the next several days. Sensible weather for our region can be impacted by these systems, the latter much more likely than the former. So while this is a low confidence forecast, as of today I lean toward high pressure keeping us fair August 16-17, and a trough from the west increasing the humidity and shower chances August 18-20, while leaning toward ensemble indications of any tropical activity staying well offshore of the East Coast. Also, there’s no major heat indicated.

DAYS 11-15 (AUGUST 21-25)

Fairly quiet pattern overall – weak weather systems may pass by with a shower threat otherwise high pressure and a general weak westerly flow dominate with mostly fair weather and no prolonged major heat.

DAYS 1-5 (AUGUST 10-14)

We enter mid August and are about to go into a quieter weather pattern. The last of the remains of what was once Hurricane / Tropical Storm Debby exits our region this morning with the last of the showers / downpours exiting Cape Ann and the NH Seacoast by 8:30 a.m. and Cape Cod by late morning. Otherwise we have fair weather to enjoy for this weekend. The warmest day will be today, which starts humid then dries out. Sunday will feature seasonably mild air with lower humidity. You’ll notice a hazy look to the sky both today and Sunday, and this is from a couple of surges of high altitude wildfire smoke that will be moving through the region. It does appear that the smoke will thin out Sunday evening to improve the viewing conditions for the Perseid meteor shower, which peaks after midnight Sunday night / Monday morning. A trough of low pressure swings through the region and may kick off a few showers on Monday, before we return to fair and pleasant weather heading toward midweek as a westerly air flow dominates.

TODAY: Clouds / showers exit eastern areas early morning (north) to mid morning (south), then sunshine with passing clouds remainder of the day. High altitude smoke. Highs 81-88. Dew point lowers into and through the 60s, into the upper 50s. Wind SW to W 5-15 MPH with a few higher gusts, relaxing during the day.

TONIGHT: High altitude smoke thins with a clear sky otherwise. Lows 60-67. Dew point sub-60. Wind W up to 10 MPH.

SUNDAY: Sunny morning. Sun/cloud mix afternoon. Additional high altitude smoke. Highs 76-83. Dew point sub-60. Wind W 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Interior lower elevation fog patches. Lows 57-64. Dew point sub-60. Wind W under 10 MPH.

MONDAY: Partly sunny. A possible shower or thunderstorm in the afternoon. Highs 77-84. Dew point near 60. Wind W 5-15 MPH.

MONDAY NIGHT: Variably cloudy. A possible shower or thunderstorm in the evening. Lows 58-65. Dew point under 60. Wind W 5-15 MPH.

TUESDAY: Mostly sunny. Highs 76-83. Dew point in 50s. Wind NW 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Lows 56-63. Dew point in 50s. Wind W up to 10 MPH.

WEDNESDAY: Mostly sunny. Highs 76-83. Dew point in 50s. Wind W 5-15 MPH.

DAYS 6-10 (AUGUST 15-19)

Fair/dry weather dominates through mid period before humidity and pop up shower/t-storm chances increase late period. No significant heat as we are in a pattern that features a westerly flow and a weak trough.

DAYS 11-15 (AUGUST 20-24)

Weak trough / westerly flow continues, with moderate temperatures and a few shower chances. No major heat indicated.

DAYS 1-5 (AUGUST 9-13)

The weather system that was once Debby will push through the region during the next 24 hours (by early Saturday morning). This results in a humid and unsettled day today, although rain coverage will not be that high until later tonight when a final band of widespread showers and embedded thunderstorms pushes through with a trailing front from the low center as it passes by to our northwest and north. Prior to that we’ll have isolated to scattered showers, though a few can be heavy, and we’ll also see a pretty decent fog blanket to start the day today before that thins out and dissipates with some increase in wind. Any breaks of sun today will be limited and most likely to occur at some point this afternoon over eastern MA and RI. Of note, there’s a little bit of wind shear available in the lower levels of the atmosphere tonight as the heavier band of showers pushes through, and while the chance is better west of the WHW forecast area, there is a tiny shot at an isolated brief and relatively weak tornado in any stronger cell. All of the unsettled weather pushes offshore right about dawn on Saturday, setting our region up for a great summer weekend. It’ll take several hours for the wet ground to dry out Saturday, otherwise it’s to be a very nice day, warm with gradually lowering humidity and a nice breeze as well. Sunday’s weather will be pleasantly warm with low humidity and a sun/cloud mix. Heading into early next week, there’s a slight change in the forecast. A disturbance I was eyeing for the potential for a shower or thunderstorm Tuesday is going to be 24 hours faster than I thought a couple days ago, bringing that shower and thunderstorm chance Monday, with fair weather returning Tuesday.

TODAY: Foggy areas through mid morning, otherwise mostly cloudy with isolated to scattered showers including a few potential downpours. Highs 72-79 but may be a little cooler immediate South Coast and Cape Cod areas. Dew point 65+. Wind SE to S up to 10 MPH, increasing to 10-20 MPH.

TONIGHT: Mainly cloudy. Isolated to scattered showers early-mid evening, more widespread showers and possible thunderstorms late evening and overnight. Areas of fog. Lows 66-73. Dew point 65+. Wind S 5-15 MPH, higher gusts possible.

SATURDAY: Clouds and showers linger Cape Cod into mid morning, otherwise a sun/cloud mix with a trend for more sun. Highs 80-87. Dew point lowers through 60s. Wind SW 5-15 MPH, higher gusts.

SATURDAY NIGHT: Clear. Lows 60-67. Dew point sub-60. Wind SW up to 10 MPH.

SUNDAY: Sunny morning. Sun/cloud mix afternoon. Highs 76-83. Dew point sub-60. Wind W 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Interior lower elevation fog patches. Lows 57-64. Dew point sub-60. Wind W under 10 MPH.

MONDAY: Partly sunny. A possible shower or thunderstorm in the afternoon. Highs 77-84. Dew point near 60. Wind W 5-15 MPH.

MONDAY NIGHT: Variably cloudy. A possible shower or thunderstorm in the evening. Lows 58-65. Dew point under 60. Wind W 5-15 MPH.

TUESDAY: Mostly sunny. Highs 76-83. Dew point in 50s. Wind NW 5-15 MPH.

DAYS 6-10 (AUGUST 14-18)

Fair / dry weather midweek next week with a westerly air flow dominating. A little more troughing from the Great Lakes to the Northeast keeps major heat away but may add a few showers to the pattern later in the week.

DAYS 11-15 (AUGUST 19-23)

Weak trough / westerly flow continues, with moderate temperatures and a few shower chances. No major heat indicated.

DAYS 1-5 (AUGUST 8-12)

Since what was Debby is now a regular low pressure area, it will act very much like one as it passes through the Northeast in the way it impacts our weather today through Saturday. What’s become a warm front will approach today and tonight with an increase in clouds from south to north (more sun north today as dry air holds the clouds at bay for several hours), and a few showers push northward into the region, but most of them struggle to survive drier air in place, with most of them occurring tonight. Friday, we find ourselves in the warm sector with a muggy flow of warmer air on a southeast to south wind, along with scattered showers. The low center passes west and north of our region Friday night and early Saturday, dragging a cold front through here with a more solid band of showers and possible thunderstorms Friday night to pre-dawn Saturday. This is when the heaviest rain will occur, but it will be so brief in duration that most amounts will fall shy of 1 inch, and it will move so quickly out of here that we have a great weekend ahead with a westerly air flow dominating. In typical summertime fashion, there’s not a lot of cooling to take place right behind what is now a “cold front”, so Saturday will be quite a warm day, but with lowering humidity. Sunday will be a pleasant summer day, warm, not humid, with sun but some fair weather clouds popping up during the day. Monday’s weather looks fair with a continued dry westerly flow.

TODAY: Most sun north and less sun south much of day, before clouds spread north later. Sprinkles of light rain mainly west of Boston late day. Highs 73-80, warmest inland. Dew point near 60. Wind N to E up to 10 MPH.

TONIGHT: Mostly cloudy. Occasional showers. Patchy fog forms. Lows 63-70. Dew point rising through 60s. Wind SE 5-15 MPH.

FRIDAY: Mostly cloudy. Episodes of showers with scattered downpours too. Fog patches early. Highs 72-79. Dew point rising over 70. Wind SE to S increasing to 10-20 MPH, higher gusts especially in coastal locations.

FRIDAY NIGHT: Cloudy. Showers becoming more widespread including downpours and possible thunderstorms. Areas of fog. Lows 66-73 with matching dew points. Wind S 10-20 MPH, higher gusts possible.

SATURDAY: Cloud/sun mix morning. Sunny afternoon. Highs 80-87. Dew point slowly lowering through 60s. Wind SW 10-20 MPH, higher gusts, diminishing later in the day.

SATURDAY NIGHT: Clear. Lows 60-67. Dew point sub-60. Wind SW up to 10 MPH.

SUNDAY: Sunny morning. Sun/cloud mix afternoon. Highs 76-83. Dew point sub-60. Wind W 5-15 MPH.

SUNDAY NIGHT: Mostly clear. Interior lower elevation fog patches. Lows 57-64. Dew point sub-60. Wind W under 10 MPH.

MONDAY: Mostly sunny. Highs 77-84. Dew point sub-60. Wind W 5-15 MPH.

DAYS 6-10 (AUGUST 13-17)

Next week’s large scale pattern is weak trough Northeast with westerly flow aloft. Other than a weak disturbance passing by about August 13 with a possible shower, it is dry pattern with near to below normal temperatures.

DAYS 11-15 (AUGUST 18-22)

Temperatures somewhat variable but close to normal for the period. A couple shower / thunderstorm episodes possible but the overall pattern looks fairly quiet.

DAYS 1-5 (AUGUST 7-11)

Some quick weather changes are coming up for us over the next several days, and while there is some unsettled weather involved in that, there will also be periods of much nicer weather, so remember not to focus on the rain drops icon that shows up on your weather app that tries to fool you into thinking it’s going to rain every day forever. 😉 This is how it really unfolds in our region. First, the wave of low pressure that delivered a swath of decent rain to the region overnight departs this morning and midday, with a drying trend during the day. The most complete drying will take place north of I-90 where some sunshine will appear midday and afternoon. A bubble of high pressure across southeastern Canada will keep our weather fair into Thursday, but during the day we’ll see an advance of high to mid level clouds associated with the moisture from what was formerly Debby. This system is already post tropical, but has not been declared post tropical by NHC yet. Regardless, it still contains a decent amount of moisture and we’ll hear from some of it, but the track of the system is going to take the bulk of that to our west on Friday, with just tropical showers in our region, following a broken band of rain Thursday night which leads much more humid air back into the region. One final band of heavier showers and possible thunderstorms will then cross the region Friday night and early Saturday as the remnant low accelerates by to our northwest, heading for southeastern Canada. This drags drier air into our region by midday Saturday, salvaging the majority of the weekend. Gusty winds that develop on Friday will also continue into Saturday as they shift from southeast to southwest, then settle down later Saturday. Except a picturesque blue sky mixed with fair weather clouds on Sunday, with pleasant air, warm but manageable humidity and a nice breeze that isn’t too strong.

TODAY: Mainly cloudy start with any showers ending and patchy fog dissipating. Clouds hang on South Coast while sun appears to the north. Highs 68-75, coolest immediate coast. Dew point 60+. Wind NE 5-15 MPH.

TONIGHT: Partly cloudy. Patchy fog. Lows 58-65. Dew point 55+. Wind N up to 10 MPH.

THURSDAY: Sunshine gives way to clouds south to north during the day. Highs 73-80, warmest inland. Dew point near 60. Wind N to E up to 10 MPH.

THURSDAY NIGHT: Mostly cloudy. Showers arrive south to north. Areas of fog develop. Lows 63-70. Dew point rising through 60s. Wind SE 5-15 MPH.

FRIDAY: Mostly cloudy. Episodes of showers with scattered downpours too. Fog patches early. Highs 72-79. Dew point rising over 70. Wind SE to S 10-20 MPH, higher gusts.

FRIDAY NIGHT: Cloudy. Showers becoming more widespread including downpours and possible thunderstorms. Areas of fog. Lows 66-73 with matching dew points. Wind S 10-20 MPH, higher gusts possible.

SATURDAY: Starts cloudy with widespread showers, then rapid clearing southwest to northeast by late morning with sun and passing clouds midday on. Highs 75-82, occurring late-day. Dew point 70+ early, then falling into 60s. Wind S 10-20 MPH with higher gusts, shifting to SW, diminishing late.

SATURDAY NIGHT: Clear. Lows 60-67. Dew point sub-60. Wind SW up to 10 MPH.

SUNDAY: Sun/cloud mix. Highs 80-87. Dew point near 60. Wind 5-15 MPH.

DAYS 6-10 (AUGUST 12-16)

Next week’s large scale pattern is weak trough Northeast with westerly flow aloft. Other than a weak disturbance passing by about August 13 with a possible shower, it looks like a dry pattern with near to below normal temperatures.

DAYS 11-15 (AUGUST 17-21)

Temperatures run near to a little below normal with a couple of episodes of unsettled weather in a continued quiet pattern with a westerly flow dominant.
