8:14AM

DAYS 1-5 (AUGUST 10-14)
A trough swings through the region today and may kick off a brief afternoon shower in some locations, but that would be a very minor interruption in what will otherwise be a great August weekend. When we get to Monday, the humidity will start to increase, though the weather will be fair, then a broad trough moving in from the west will bring shower and thunderstorm chances for Tuesday into Wednesday.
Forecast details…
TODAY: Sunny to partly cloudy. Brief passing shower possible west to east during the afternoon. Highs 77-84, coolest hills. Wind W 5-15 MPH.
TONIGHT: Mostly clear. Lows 53-60. Wind light NW.
SUNDAY: Sunny. Highs 77-84, coolest coast. Wind light variable with sea breezes.
SUNDAY NIGHT: Clear. Lows 55-62. Wind light SW.
MONDAY: Partly sunny. Highs 80-87. Wind SW 5-15 MPH.
MONDAY NIGHT: Variably cloudy. Humid. Lows 60-67. Wind light SW.
TUESDAY: Mostly cloudy. Chance of showers and possible thunderstorms. Humid. Highs 78-85. Wind S 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Chance of showers. Humid. Lows 61-68. Wind light variable.
WEDNESDAY: Mostly cloudy. Chance of showers. Humid. Highs 73-80. Wind light variable.

DAYS 6-10 (AUGUST 15-19)
Trough departs and high pressure builds in with fair and dry weather returning August 15. High pressure should maintain control overall with a warm-up August 16-17, then a trough from the west may bring showers/thunderstorms during the August 18-19 time frame.

DAYS 11-15 (AUGUST 20-24)
Overall pattern will be weak west to east flow with a northward-displaced jet stream, allowing more heat/humidity back into the region. Can’t rule out a few opportunities for showers/thunderstorms, but much of this period looks rain-free.

7:34AM

DAYS 1-5 (AUGUST 9-13)
2 minor changes for this update. Removing the pop-up shower/storm from today’s forecast and adding it for a brief time window to Saturday, as it doesn’t look like we have enough instability to trigger anything today and a small but vigorous trough will pass by during the first half of Saturday afternoon, possibly triggering a shower to interrupt a few outdoor plans briefly. Many areas will not see anything, however, and we pretty much have a 3-day stretch of great weather starting today. Nice weather will probably carry through most of if not all of Monday (leaning toward the latter) as high pressure sinks to the south of the region. By Tuesday, a trough from the west approaches and we enter the next period of unsettled weather with an increased risk for shower activity, more clouds, and more humidity.
Forecast details…
TODAY: Mostly sunny to partly cloudy. Highs 78-85. Wind W 5-15 MPH, few higher gusts.
TONIGHT: Mostly clear. Lows 55-62. Wind W up to 10 MPH.
SATURDAY: Partly cloudy. Brief passing shower possible west to east midday to mid afternoon. Highs 77-84, coolest hills. Wind W 5-15 MPH.
SATURDAY NIGHT: Mostly clear. Lows 53-60. Wind light NW.
SUNDAY: Sunny. Highs 77-84, coolest coast. Wind light variable with sea breezes.
SUNDAY NIGHT: Clear. Lows 55-62. Wind light SW.
MONDAY: Partly sunny. Highs 80-87. Wind SW 5-15 MPH.
MONDAY NIGHT: Variably cloudy. Humid. Lows 60-67. Wind light SW.
TUESDAY: Mostly cloudy. Chance of showers. Humid. Highs 78-85. Wind S 5-15 MPH.

DAYS 6-10 (AUGUST 14-18)
A low pressure area crosses the region August 14 with showery conditions. High pressure builds in with fair and dry weather August 15. High pressure should maintain control overall with a warm-up August 16-17, then a trough from the west may bring showers/thunderstorms by the end of the period.

DAYS 11-15 (AUGUST 19-23)
Overall pattern will be weak west to east flow with a northward-displaced jet stream, allowing more heat/humidity back into the region. Can’t rule out a few opportunities for showers/thunderstorms, but much of this period looks rain-free.

7:20AM

DAYS 1-5 (AUGUST 8-12)
Humidity comes down a peg today, but doesn’t really crash until a cold front crosses the region in the early hours of Friday. An initial trough responsible for lots of rain (for many areas) and lots of lightning (for some areas) during last night is offshore but with humidity in place and still one more front to approach and pass through, we can’t rule out a few more showers/storms today, although they will be much more isolated. By Friday, we start a 3 day stretch of comfortable weather, with the only rain threat being the possibility of an isolated pop up shower or thunderstorm on Friday as we combine still warm surface air with colder air aloft and pop instability clouds. Weekend weather? About as nice as you can get in August, although the nights will be on the cool side and may cause you to think of autumn. Monday’s weather also looks nice but we should see a quick warm-up and a bit of a humidity increase as well as high pressure sinks south.
Forecast details…
TODAY: Partly sunny. Isolated to scattered showers/thunderstorms. Moderately humid. Highs 80-87. Wind SW 5-15 MPH.
TONIGHT: Partly cloudy. Less humid. Lows 60-67. Wind shifting to W 5-15 MPH.
FRIDAY: Partly cloudy. Isolated afternoon showers/thunderstorms. Highs 78-85. Wind NW 10-20 MPH.
FRIDAY NIGHT: Partly cloudy. Lows 55-62. Wind NW 5-15 MPH.
SATURDAY: Sunny to partly cloudy. Highs 77-84, coolest interior hills. Wind NW 5-15 MPH.
SATURDAY NIGHT: Mostly clear. Lows 53-60. Wind light NW.
SUNDAY: Sunny. Highs 77-84, coolest coast. Wind light variable with sea breezes.
SUNDAY NIGHT: Clear. Lows 55-62. Wind light SW.
MONDAY: Partly sunny. Highs 80-87. Wind SW 5-15 MPH.

DAYS 6-10 (AUGUST 13-17)
A broad trough of low pressure helps the jet stream sink south and brings higher humidity and showery weather August 13-14, before high pressure builds back in with drier and pleasant weather August 15-17, starting a little cooler then turning somewhat warmer.

DAYS 11-15 (AUGUST 18-22)
Drier pattern expected as the jet stream lifts to the north and high pressure builds into the eastern US, but look for increasing heat and humidity during this period. Shower/thunderstorm risk should be minimal for much of this period.

7:15AM

DAYS 1-5 (AUGUST 7-11)
Humidity spikes today and Thursday, but without high heat, however it will feel hot today as sunshine will work on the humidity for a while before we pop isolated thunderstorms the first half of the afternoon, then more clustered storm activity favoring areas west of Boston the second half of the afternoon which will progress eastward tonight. The focus for severe storms starts out to the west and eventually ends up in southeastern MA during tonight. Severe storms would be most likely to produce damaging wind gusts, which includes brief tornadoes. The main activity should be pretty much done by early Thursday but with the cold front still to the west we can still see additional storms pop up on Thursday, although the support will be a little less and the storm numbers should be down. The cold front gets through the region Thursday night at which time the humidity level takes a dive, and we stay rather warm but much drier Friday, when the combination of ground heating and cooler air coming in aloft may allow an isolated shower or thunderstorm to pop up on what otherwise will be a dry day for most. Weekend? Excellent! Dry weather, low humidity, warm days, cool nights.
Forecast details…
TODAY: Variably cloudy. Areas of fog early. Isolated showers/thunderstorms early to mid afternoon anywhere. Scattered to numerous showers/thunderstorms favoring central and northeastern MA and southern NH with isolated showers/storms possible elsewhere mid afternoon on. Any storms may be strong to locally severe. Humid. Highs 81-88. Wind SW 5-15 MPH, higher gusts.
TONIGHT: Mostly cloudy. Showers/thunderstorms likely, with isolated severe storms possible. Areas of fog. Humid. Lows 63-70. Wind SW 5-15 MPH, but strong gusts possible near any storms.
THURSDAY: Partly sunny. Isolated to scattered showers/thunderstorms until about mid afternoon. Humid. Highs 80-87. Wind SW 5-15 MPH.
THURSDAY NIGHT: Partly cloudy. Less humid. Lows 60-67. Wind shifting to W 5-15 MPH.
FRIDAY: Partly cloudy. Isolated afternoon showers/thunderstorms. Highs 78-85. Wind NW 10-20 MPH.
FRIDAY NIGHT: Partly cloudy. Lows 55-62. Wind NW 5-15 MPH.
SATURDAY: Sunny to partly cloudy. Highs 77-84, coolest interior hills. Wind NW 5-15 MPH.
SATURDAY NIGHT: Mostly clear. Lows 53-60. Wind light NW.
SUNDAY: Sunny. Highs 77-84, coolest coast. Wind light variable with sea breezes.

DAYS 6-10 (AUGUST 12-16)
High pressure settles to the south with increasing warmth and humidity August 12-13, dry August 12, risk of showers/storms later August 13. Trough moves through with showers/storms August 14, high humidity but cooler air. Drier, more seasonable weather for the end of the period as high pressure builds in behind the departing trough.

DAYS 11-15 (AUGUST 17-21)
Dry pattern expected as the jet stream lifts to the north and high pressure builds into the eastern US, but look for increasing heat and humidity with time.

7:08AM

DAYS 1-5 (AUGUST 6-10)
A warm front crosses the region today, parented from a low pressure area in east central Canada. A separate low will be tracking south of New England and may toss a few showers close to the South Coast especially the islands off Cape Cod. Otherwise, look for a mainly rain-free day but an increase in humidity today, and then a spike in humidity at midweek as a cold front approaches. The timing of this front is such that most of the shower/thunderstorm activity will occur to the west during the day Wednesday, moving into the region later Wednesday night into Thursday before pushing off to the east. Although some strong storms are possible, this timing should spare the region severe storms. Refreshing dry air will arrive later in the week, but a few instability showers/storms may pop up due to colder air aloft and a still fairly warm surface on Friday. By Saturday, expect dry weather across the region.
Forecast details…
TODAY: Areas of fog early to mid morning. Variably cloudy. Isolated showers South Coast. More humid. Highs 80-87. Wind S to SW 5-15 MPH.
TONIGHT: Variably cloudy. Humid. Lows 62-69. Wind SW 5-15 MPH.
WEDNESDAY: Variably cloudy. Scattered afternoon showers/thunderstorms, favoring areas west of a Boston-Providence line. Humid. Highs 81-88. Wind SW 10-20 MPH.
WEDNESDAY NIGHT: Variably cloudy. Increasing risk of showers/thunderstorms west to east. Patchy fog. Humid. Lows 63-70. Wind SW 5-15 MPH.
THURSDAY: Variably cloudy. Scattered showers/thunderstorms likely, favoring morning and early afternoon. Humid. Highs 80-87. Wind SW 5-15 MPH shifting to W.
THURSDAY NIGHT: Partly cloudy. Less humid. Lows 60-67. Wind W 5-15 MPH.
FRIDAY: Partly cloudy. Isolated afternoon showers/thunderstorms. Highs 78-85. Wind NW 10-20 MPH.
FRIDAY NIGHT: Partly cloudy. Lows 53-60. Wind NW 5-15 MPH.
SATURDAY: Sunny to partly cloudy. Highs 77-84. Wind NW 5-15 MPH.

DAYS 6-10 (AUGUST 11-15)
Pleasant/dry August 11 as high pressure dominates. High pressure pushes to the south with fair weather and a warm-up August 12. More humid with a shower/thunderstorm risk August 13-14 as trough crosses the region from west to east. High pressure and fair weather return at the end of the period.

DAYS 11-15 (AUGUST 16-20)
Dry pattern expected as the jet stream lifts to the north and high pressure builds into the eastern US, but look for increasing heat and humidity with time.

7:01AM

DAYS 1-5 (AUGUST 5-9)
High pressure builds in today bringing the best weather of the next 5 days, sunshine, seasonably warm air, and low humidity. But things change in a hurry as a warm front moves across the region from southwest to northeast early Tuesday, re-introducing higher humidity to the region, which will stick around (pun intended) into Thursday until a cold front moves across the region. Shower and thunderstorm chances will exist later Tuesday, returning Wednesday, favoring areas to the west, and Thursday, favoring all areas. Whether or not any severe storms occur remains to be seen, and something we’ll fine-tune in the next few updates. By Friday, that cold front will have moved offshore and we’ll be back into drier air, but some chilly air aloft will make the atmosphere unstable and we’ll have to watch for pop up showers and thunderstorms that day.
Forecast details…
TODAY: Mostly sunny. Highs 79-86, coolest coast. Wind light variable with light coastal sea breezes.
TONIGHT: Partly cloudy. Lows 60-67. Wind S under 10 MPH.
TUESDAY: Variably cloudy. Mid to late afternoon shower or thunderstorm possible. More humid. Highs 80-87. Wind S to SW 5-15 MPH.
TUESDAY NIGHT: Variably cloudy. Humid. Lows 62-69. Wind SW 5-15 MPH.
WEDNESDAY: Partly sunny. Scattered afternoon showers/thunderstorms, favoring areas west of a Boston-Providence line. Humid. Highs 81-88. Wind SW 10-20 MPH.
WEDNESDAY NIGHT: Variably cloudy. Risk of a shower or thunderstorm. Patchy fog. Humid. Lows 63-70. Wind SW up to 10 MPH.
THURSDAY: Variably cloudy. Scattered showers/thunderstorms likely. Humid. Highs 80-87. Wind SW 5-15 MPH.
THURSDAY NIGHT: Partly cloudy. Risk of a shower or thunderstorm early. Patchy fog evening. Less humid. Lows 60-67. Wind W 5-15 MPH.
FRIDAY: Partly cloudy. Isolated afternoon showers/thunderstorms. Highs 78-85. Wind NW 10-20 MPH.

DAYS 6-10 (AUGUST 10-14)
The August 10-11 weekend looks dry and comfortable with temperatures averaging slightly below normal – a slight hint of fall days ahead. Warming back up the first half of the following week August 12-14 with fair weather to start then an increasing risk of shower/t-storms as the jet stream dips and a broad trough of low pressure moves into the Northeast.

DAYS 11-15 (AUGUST 15-19)
Fair, drier and cooler weather returns the first couple days of this period followed by increasing heat/humidity later in the period as the jet stream lifts to the north and high pressure ridging builds into the eastern US.

7:48AM

DAYS 1-5 (AUGUST 4-8)
A low pressure trough near the South Coast may trigger a few pop up showers/storms there today, otherwise it’s fair and drying elsewhere. High pressure will bring beautiful weather Monday, then a long-advertised period of more unsettled weather arrives Tuesday to Thursday. Expecting there to be several opportunities for showers and thunderstorms, with the day that is of most concern for stronger storms being Wednesday. There will be much fine-tuning to do in future blog updates.
Forecast details…
TODAY: Mostly sunny to partly cloudy. Isolated showers and thunderstorms possible late morning southeastern MA, RI, and adjacent eastern CT. Highs 79-86. Wind NW up to 10 MPH.
TONIGHT: Mostly clear. Lows 58-65. Wind light N.
MONDAY: Mostly sunny. Highs 78-85, coolest coast. Wind light variable with light coastal sea breezes.
MONDAY NIGHT: Mostly clear. Lows 55-62. Wind light variable.
TUESDAY: Increasing cloudiness. Chance of showers late-day. Highs 77-84, coolest coast. Wind light SE.
TUESDAY NIGHT: Mostly cloudy. Chance of showers. More humid. Lows 62-69. Wind S 5-15 MPH.
WEDNESDAY: Variably cloudy. Showers/thunderstorms likely. Humid. Highs 78-85. Wind SW 10-20 MPH.
WEDNESDAY NIGHT: Mostly cloudy. Showers/thunderstorms likely. Humid. Lows 63-70. Wind SW 5-15 MPH.
THURSDAY: Variably cloudy. Chance of showers and possible thunderstorms. Less humid. Highs 76-84. Wind W 5-15 MPH.

DAYS 6-10 (AUGUST 9-13)
August 9 may see a few additional showers and thunderstorms as a broad low pressure trough moves through the region. The August 10-11 weekend looks dry overall but some cool air aloft may trigger a few instability showers, and it may end up a little cooler than average. Possible quick warm-up to end the period as high pressure builds offshore, pushes the trough out, and a southerly air flow develops.

DAYS 11-15 (AUGUST 14-18)
With high pressure ridging strongest over the US Plains and Midwest, this allows more troughing to drop through the Great Lakes and Northeast and another one will likely do that the first half of this period with a few shower/thunderstorm episodes and no major heat. Drier/warmer weather later in the period as the trough lifts out and high pressure builds in.

9:28AM

DAYS 1-5 (AUGUST 3-7)
A trough of low pressure will move across southeastern New England slowly today through Sunday. It will have cleared most of the region by Sunday morning hanging up around the South Coast for a while during Sunday. This trough may trigger a few showers and thunderstorms favoring areas from the Boston-Providence corridor northwestward today and this evening, and to the southeast of the B-P line on Sunday. It’ll be a warm weekend, but not too hot. Humidity starts out a bit higher today then drops off during Sunday as drier air arrives from Canada. This sets up a splendid Monday as high pressure builds in, then we get more unsettled in the Tuesday-Wednesday period as first a warm front crosses the region with cloudiness and a shower threat, then a cold front brings showers and thunderstorms during Wednesday. We’ll have to keep a close eye on the Wednesday activity, while it’s at day 5 and uncertain, we may have to deal with some strong storms. Forecast details…
TODAY: Variably cloudy. Scattered showers north and west of Boston this morning. Isolated showers/thunderstorms, favoring southern NH, northern and central MA, eastern CT, and northwestern RI this afternoon. Moderately humid. Highs 78-83 coast, 83-88 interior. Wind SW up to 10 MPH except coastal sea breezes.
TONIGHT: Partly cloudy. Isolated showers/thunderstorms possible very early. Moderately humid. Lows 62-69. Wind light SW to W.
SUNDAY: Partly cloudy southern RI and southeastern MA with isolated showers and thunderstorms possible. Mostly sunny elsewhere. Less humid. Highs 79-86. Wind NW up to 10 MPH.
SUNDAY NIGHT: Mostly clear. Lows 58-65. Wind light N.
MONDAY: Mostly sunny. Highs 78-85, coolest coast. Wind light variable with light coastal sea breezes.
MONDAY NIGHT: Mostly clear. Lows 55-62. Wind light variable.
TUESDAY: Increasing cloudiness. Chance of showers late-day. Highs 77-84, coolest coast. Wind light SE.
TUESDAY NIGHT: Mostly cloudy. Chance of showers. More humid. Lows 62-69. Wind S 5-15 MPH.
WEDNESDAY: Variably cloudy. Showers/thunderstorms likely. Humid. Highs 78-85. Wind SW 10-20 MPH.

DAYS 6-10 (AUGUST 8-12)
August 8-9 may see a few additional showers and thunderstorms as a broad low pressure trough moves through the region. The August 10-11 weekend looks dry overall but some cool air aloft may trigger a few instability showers, and it may end up a little cooler than average. Possible quick warm-up to end the period as high pressure builds offshore, pushes the trough out, and a southerly air flow develops.

DAYS 11-15 (AUGUST 13-17)
With high pressure ridging strongest over the US Plains and Midwest, this allows more troughing to drop through the Great Lakes and Northeast and another one will likely do that the first half of this period with a few shower/thunderstorm episodes and no major heat. Drier/warmer weather later in the period as the trough lifts out and high pressure builds in.

7:42AM

DAYS 1-5 (AUGUST 2-6)
High pressure brings a “top ten” day today. In reality there are probably more like 20 of these days in any given year but, top ten works. The weekend features a tad bit more humidity and a risk of a passing shower or thunderstorm favoring western and northern areas later Saturday and a pop up shower or storm South Coast Sunday as a weak trough moves through the region. Another Canadian high pressure area brings great weather for Monday before some humidity and cloudiness with shower risk arrives Tuesday as a trough moves into the Great Lakes.
Forecast details…
TODAY: Mostly sunny. Highs 78-85, coolest along the shore. Wind light variable with sea breezes.
TONIGHT: Mostly clear. Lows 60-67. Wind light variable.
SATURDAY: Mostly sunny to partly cloudy. Slight risk of isolated thunderstorms favoring areas north and west of Boston late-day. More humid. Highs 83-90. Wind light SW.
SATURDAY NIGHT: Partly cloudy. Humid. Lows 65-72. Wind light SW.
SUNDAY: Partly sunny. Isolated showers and thunderstorms mainly South Coast midday-afternoon. Moderately humid. Highs 85-92 except 78-85 Cape Cod and immediate coastal areas. Wind variable 5-15 MPH with sea breezes.
SUNDAY NIGHT: Mostly clear. Less humid. Lows 61-68. Wind NW 5-15 MPH.
MONDAY: Mostly sunny. Highs 78-85. Wind N 5-15 MPH.
MONDAY NIGHT: Partly cloudy. Lows 60-67. Wind light W.
TUESDAY: Variably cloudy. Risk of late-day showers. Highs 80-87. Wind SW 5-15 MPH.

DAYS 6-10 (AUGUST 7-11)
A broad trough will move across the region August 7-8 with a risk of a few episodes of showers and thunderstorms. This trough will weaken but may slow down resulting in a few pop up showers later in the period but overall fair weather and a lack of significant heat.

DAYS 11-15 (AUGUST 12-16)
Trough exits to east and a more west to east flow takes over with warmer, more humid air at times, and a risk of a few episodes of showers/thunderstorms amidst mainly rain-free weather.

7:25AM

DAYS 1-5 (AUGUST 1-5)
As August gets underway we’ll be under the influence of high pressure which had its origins in Canada and has some drier and slightly cooler air with it, giving the region a break from the humid heat that dominated the last few days of July. We’ll have to watch for a few showers near a sea breeze boundary this afternoon but overall it will be a dry day. As we get into the weekend, the high will slip offshore allowing the humidity to bump up somewhat, but a trough will slide through the region during this time, maybe kicking off a shower or thunderstorm in a few areas. Behind this another high pressure area will build in with the air quite comfortable again by Monday.
Forecast details…
TODAY: Mostly sunny to partl cloudy. Risk of an isolated afternoon shower southeastern NH, eastern MA, and northern RI. Less humid. Highs 80-87. Wind light NW to N with coastal sea breezes developing.
TONIGHT: Mostly clear. Patchy fog interior low elevations. Lows 58-65. Wind light variable.
FRIDAY: Mostly sunny. Highs 78-85, coolest along the shore. Wind light variable with sea breezes.
FRIDAY NIGHT: Mostly clear. Lows 60-67. Wind light variable.

SATURDAY NIGHT: Partly cloudy. Humid. Lows 65-72. Wind light SW.
SUNDAY: Partly sunny. Isolated showers and thunderstorms. Humid. Highs 85-92. Wind SW 5-15 MPH.
SUNDAY NIGHT: Mostly clear. Less humid. Lows 61-68. Wind NW 5-15 MPH.
MONDAY: Mostly sunny. Highs 78-85. Wind N 5-15 MPH.

DAYS 6-10 (AUGUST 6-10)
A broad trough will move across the region August 6-8 with a risk of a few episodes of showers and thunderstorms, a brief spike of heat possible then a cooling trend. High pressure builds in with fair weather by August 9-10.

DAYS 11-15 (AUGUST 11-15)
The upper pattern will feature high pressure ridging further west in the US and well off the Atlantic Coast which will allow the jet stream to sink a little further south, preventing major heat and bringing occasional shower and thunderstorm threats for mid August.

7:14AM

DAYS 1-5 (JULY 31-AUGUST 4)
High pressure offshore delivers one more day of heat/humidity but a cold front moving into the area will trigger afternoon thunderstorms. Not every location will be hit directly but those that are could see a strong storm with downpours, lightning, and locally gusty winds. Conditions will settle down tonight as the storms lose support from heating and the front itself will make its way to just offshore by morning, so a morning shower may occur near Cape Cod Thursday, and a pop up afternoon shower is possible near a sea breeze boundary, otherwise high pressure will build in later Thursday through Friday with some great weather to start off August. Some humidity will return over the weekend along with a risk of a few showers and thunderstorms as a trough of low pressure makes its way into the region.
Forecast details…
TODAY: Mostly sunny morning. Variably cloudy afternoon with scattered showers/thunderstorms. Humid. Highs 86-93. Wind SW 5-15 MPH.
TONIGHT: Mostly cloudy. Scattered showers and a risk of thunderstorms. Humid. Lows 66-73. Wind light variable.
THURSDAY: Partly sunny. Chance of showers early morning, Cape Cod. Risk of an isolated afternoon shower southeastern NH, eastern MA, and northern RI. Less humid. Highs 80-87. Wind light NW to N with coastal sea breezes developing.
THURSDAY NIGHT: Mostly clear. Patchy fog interior low elevations. Lows 58-65. Wind light variable.
FRIDAY: Mostly sunny. Highs 78-85, coolest along the shore. Wind light variable with sea breezes.
FRIDAY NIGHT: Mostly clear. Lows 60-67. Wind light variable.
SATURDAY: Mostly sunny to partly cloudy. Slight risk of isolated thunderstorms. More humid. Highs 83-90. Wind light SW.
SATURDAY NIGHT: Partly cloudy. Humid. Lows 65-72. Wind light SW.
SUNDAY: Partly sunny. Isolated to scattered showers and thunderstorms. Humid. Highs 85-92. Wind SW 5-15 MPH.

DAYS 6-10 (AUGUST 5-9)
Weak high pressure brings fair weather August 5. A broad trough will move across the region sending a stronger front through the region with more cloudiness and a cooling trend with a couple episodes of unsettled weather during the August 6-8 period. High pressure builds in with fair weather by August 9.

DAYS 11-15 (AUGUST 10-14)
The upper pattern will feature high pressure ridging further west in the US and well off the Atlantic Coast which will allow the jet stream to sink a little further south, preventing major heat and bringing occasional shower and thunderstorm threats heading into mid August.

6:53AM

DAYS 1-5 (JULY 30-AUGUST 3)
High pressure off the East Coast brings heat and humidity for the final 2 days of July, something you may expect this time of year. Today’s risk of thunderstorms will be from the pop up variety, basically air-mass storms that bubble up in the heat of the day and rain themselves out. They can redevelop unevenly along a path before losing steam. As the sun starts to get lower in the sky, any of this activity should disappear for the day. Tomorrow’s threat may wait longer to occur but will be triggered by an approaching cold front, and more of the region may be impacted between mid afternoon and mid evening. The front that brings this activity to the region will move offshore Thursday and high pressure will then build in later Thursday through Friday with great summer weather, before the high slips offshore Saturday allowing a bit more humidity and heat back into the region.
Forecast details…
TODAY: Mostly sunny to partly cloudy. Isolated afternoon showers and thunderstorms. Humid. Highs 88-95. Wind SW up to 10 MPH.
TONIGHT: Partly cloudy. Risk of a shower or thunderstorm early. Humid. Lows 67-74. Wind light SW.
WEDNESDAY: Variably cloudy. Scattered to numerous afternoon thunderstorms, especially afternoon and evening. Humid. Highs 84-91. Wind SW 5-15 MPH.
WEDNESDAY NIGHT: Mostly cloudy. Scattered showers and a risk of thunderstorms. Humid. Lows 66-73. Wind light variable.
THURSDAY: Partly sunny. Chance of showers early morning, favoring southeastern MA. Less humid. Highs 80-87. Wind NW 5-15 MPH.
THURSDAY NIGHT: Mostly clear. Patchy fog interior low elevations. Lows 58-65. Wind light variable.
FRIDAY: Mostly sunny. Highs 78-85, coolest along the shore. Wind light variable with sea breezes.
FRIDAY NIGHT: Mostly clear. Lows 60-67. Wind light variable.
SATURDAY: Mostly sunny. Highs 83-90. Wind light SW.

DAYS 6-10 (AUGUST 4-8)
Heat and humidity August 4 with a risk of thunderstorms later in the day as a dissipating cold front approaches the region from the west. Weak high pressure brings fair weather August 5. A broad trough will move across the region sending a stronger front through the region with more cloudiness and a cooling trend with a couple episodes of unsettled weather during the August 6-8 period.

DAYS 11-15 (AUGUST 9-13)
High pressure from the Upper Midwest brings fair, pleasant weather to start the period then a gradual build in humidity and some heat thereafter with a risk of showers/thunderstorms returning later in the period.

6:56AM

DAYS 1-5 (JULY 29-AUGUST 2)
High pressure off the East Coast brings heat and humidity to start this week. Both today and Tuesday will carry risk of pop up afternoon showers and thunderstorms, though that risk will be fairly small for any given area, and will favor southern MA southward today, and areas well west and north of Boston Tuesday. On Wednesday, the heat will be down a notch due to more cloudiness, but the humidity will be high, and the shower/thunderstorm risk will go up for all areas as a cold front approaches. This front will pass through the region by early Thursday and after a few lingering showers possible to start that day, the first couple days of August will feature seasonably warm weather with a lowering of humidity levels as high pressure builds in from southern Canada and the Great Lakes.
Forecast details…
TODAY: Partly sunny. Humid. Isolated to scattered afternoon thunderstorms, favoring areas near and south of I-90. Highs 86-93. Wind SW 5-15 MPH.
TONIGHT: Partly cloudy. Risk of a shower or thunderstorm early. Humid. Lows 66-73. Wind light SW.
TUESDAY: Mostly sunny to partly cloudy. Isolated mid to late afternoon showers and thunderstorms favoring central MA and southern NH. Humid. Highs 86-93. Wind SW 5-15 MPH.
TUESDAY NIGHT: Partly cloudy. Risk of a shower or thunderstorm early. Humid. Lows 67-74. Wind light SW.
WEDNESDAY: Variably cloudy. Scattered to numerous afternoon thunderstorms, especially afternoon and evening. Humid. Highs 84-91. Wind SW 5-15 MPH.
WEDNESDAY NIGHT: Mostly cloudy. Scattered showers and a risk of thunderstorms. Humid. Lows 66-73. Wind light variable.
THURSDAY: Partly sunny. Chance of showers early morning, favoring southeastern MA. Less humid. Highs 80-87. Wind NW 5-15 MPH.
THURSDAY NIGHT: Mostly clear. Patchy fog interior low elevations. Lows 58-65. Wind light variable.
FRIDAY: Mostly sunny. Highs 78-85, coolest along the shore. Wind light variable with sea breezes.

DAYS 6-10 (AUGUST 3-7)
August 3-4 weekend looks typical mid summer with very warm, somewhat humid weather. There will be a risk of isolated pop up showers and thunderstorms August 3 but a slightly greater chance of isolated to scattered activity August 4 as a dissipating front moves into the area. Weak high pressure should bring dry weather August 5 before another front moves into the region with more cloudiness at times and a risk of some shower and thunderstorm activity by later August 6 into August 7.

DAYS 11-15 (AUGUST 8-12)
High pressure from the Upper Midwest brings fair, pleasant weather to start the period then a gradual build in humidity and some heat thereafter with a risk of showers/thunderstorms returning later in the period.

10:33AM

DAYS 1-5 (JULY 28-AUGUST 1)
About as typical a summertime pattern as you can have around here in mid summer. Kind of fits doesn’t it? A weakening frontal boundary may trigger a shower or thunderstorm in a few locations tonight and again during the daytime heating Monday. A stronger frontal boundary may do the same during Wednesday and Wednesday night, lingering into early Thursday. Those are your primary “wet weather threats” this 5-day period, which will often by rain-free, and feature low-grade summer heat and humidity, easing a bit as the stronger front gets through the region during Thursday.

DAYS 6-10 (AUGUST 2-6)
More typical summer weather in the early days of August with high pressure bringing fair weather August 2, another weakening frontal boundary nearing the region on the August 3-4 weekend with minimal shower/thunderstorm risk, then a stronger front driving out of Canada with a slightly more vigorous low pressure trough which may enhance the shower/thunderstorm risk around August 5-6.

DAYS 11-15 (AUGUST 7-11)
Low pressure trough will cross the Great Lakes / Northeast with slightly cooler weather but as warm/humid air tries to make a come-back, some cloudiness and showers may occur early in the period, with then a transition to a more typical late summer warm/humid, minimal shower/storm risk set-up later in the period as a weak west to east flow takes over.

6:58AM

DAYS 1-5 (JULY 27-31)
High pressure keeps control of the weather this weekend then gradually relinquishes control of it during the first half of next week, but not completely, as the high will be offshore and combine with a weakening approaching frontal boundary to increase heat, humidity, and the risk of thunderstorms.
Forecast details…
TODAY: Mostly sunny to partly cloudy. Isolated afternoon showers/thunderstorms away from the coast. Highs 83-90. Wind SW up to 10 MPH but coastal sea breezes.
TONIGHT: Mostly clear. Lows 62-69. Wind light SW.
SUNDAY: Mostly sunny to partly cloudy. Highs 85-92. Wind SW 5-15 MPH.

MONDAY: Partly sunny. Humid. Isolated afternoon thunderstorms. Highs 86-93. Wind SW 5-15 MPH.
MONDAY NIGHT: Partly cloudy. Humid. Lows 66-73. Wind light SW.

TUESDAY NIGHT: Partly cloudy. Humid. Lows 67-74. Wind light SW.
WEDNESDAY: Variably cloudy. Numerous afternoon thunderstorms. Humid. Highs 85-92. Wind SW 5-15 MPH.

DAYS 6-10 (AUGUST 1-5)
An old frontal boundary washes out over the region and weak high pressure regains control with a decreasing shower and thunderstorm risk and typically warm and moderately humid weather for the first few days of August. A stronger cold front approaches and arrives from the west later in the period with a greater risk of showers/thunderstorms as an upper trough drives into the Great Lakes from Canada.

DAYS 11-15 (AUGUST 6-10)
A stronger cold front crosses and departs the region early in the period with a shot of slightly cooler air to follow it with a risk of showers/storms to start the period, then drier weather, then a return to a more typical August feel comes right behind that with minimal thunderstorm risk.
