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: 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 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.
Forecast details…
TODAY: Mostly sunny to partly cloudy. Highs 85-92. Wind SW 5-15 MPH.
TONIGHT: Partly cloudy. Remote risk of an isolated shower mainly central MA and southern NH evening. Lows 65-72. Wind SW 5-15 MPH.
MONDAY: Partly sunny. Humid. Isolated to scattered afternoon thunderstorms. Highs 86-93. Wind SW 5-15 MPH.
MONDAY NIGHT: Partly cloudy. Risk of a shower or thunderstorm early. Humid. Lows 66-73. Wind light SW.
TUESDAY: Mostly sunny. Humid. Highs 86-93. Wind SW 5-15 MPH.
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.
WEDNESDAY NIGHT: Mostly cloudy. Scattered showers and a risk of thunderstorms. Humid. Lows 66-73. Wind light variable.
THURSDAY: Partly sunny. Chance of showers in the morning. Less humid. Highs 80-87. Wind NW 5-15 MPH.

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.
SUNDAY NIGHT: Partly cloudy. Remote risk of an isolated shower mainly central MA and southern NH evening. Lows 65-72. 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: Partly sunny. Scattered afternoon thunderstorms. Humid. Highs 86-93. Wind SW 5-15 MPH.
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.

7:28AM

DAYS 1-5 (JULY 26-30)
High pressure will be in general control of the weather during this 5-day stretch, but there will be minimal shower and thunderstorm threats from sea breeze boundaries the next few days and a dissipating front getting into the region later in the period. Don’t cancel any outdoor plans on any of these days.
Forecast details…
TODAY: Mostly sunny to partly cloudy. Slight risk of isolated showers afternoon. Highs 80-87, coolest coast. Wind light variable with coastal sea breezes.
TONIGHT: Mostly clear. Lows 60-67. Wind light S.
SATURDAY: Mostly sunny to partly cloudy. Remote risk of an isolated shower inland areas late-day. Highs 83-90. Wind SW up to 10 MPH but coastal sea breezes developing.
SATURDAY NIGHT: Mostly clear. Lows 62-69. Wind light SW.
SUNDAY: Mostly sunny to partly cloudy. Highs 85-92. Wind SW 5-15 MPH.
SUNDAY NIGHT: Partly cloudy. Remote risk of an isolated shower mainly central MA and southern NH evening. Lows 65-72. 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: Partly sunny. Isolated afternoon thunderstorms. Humid. Highs 86-93. Wind SW 5-15 MPH.

DAYS 6-10 (JULY 31-AUGUST 4)
Typical summer pattern to end July and start August, warm to hot, some humidity but not extreme, and a few opportunities for showers and thunderstorms, especially July 31 and August 1 as an old frontal boundary gradually dissipates in the region. The storm risk may go up by later August 4 as a stronger front approaches the region from the west.

DAYS 11-15 (AUGUST 5-9)
A stronger front may cross the region early in the period with a shot of slightly cooler air to follow it, then a return to a more typical August feel comes right behind that with minimal thunderstorm risk.

6:48AM

DAYS 1-5 (JULY 25-29)
A shield of high cloudiness associated with an offshore front and wave of low pressure is hiding the sun in eastern areas to start today, but it will be back soon as that moves away. High pressure will dominate our weather through the coming weekend with a gradual warm up and gradual increase in humidity, rather typical July weather. We will have to watch for an isolated pop up shower today or tomorrow with the aid of a sea breeze boundary in southeastern NH, eastern MA, and possibly RI, but the risk is very low and not worth altering any plans.
Forecast details…
TODAY: Early cloudiness eastern areas departs for sunshine, then mostly sunny to partly cloudy. Slight risk of isolated showers afternoon.
Highs 78-85, coolest coast. Wind light N with coastal sea breezes.
TONIGHT: Mostly clear. Lows 58-65. Wind light variable.
FRIDAY: Mostly sunny to partly cloudy. Slight risk of isolated showers afternoon. Highs 80-87, coolest coast. Wind light variable with coastal sea breezes.
FRIDAY NIGHT: Mostly clear. Lows 60-67. Wind light S.
SATURDAY: Mostly sunny. Highs 83-90. Wind SW up to 10 MPH.
SATURDAY NIGHT: Mostly clear. Lows 62-69. Wind light SW.
SUNDAY: Mostly sunny. Highs 85-92. Wind SW 5-15 MPH.
SUNDAY NIGHT: Mostly clear. Lows 65-72. Wind SW 5-15 MPH.
MONDAY: Partly sunny. Isolated afternoon thunderstorms. Highs 86-93. Wind SW 5-15 MPH.

DAYS 6-10 (JULY 30-AUGUST 3)
Typical summer pattern to end July and start August, warm to hot, some humidity but not extreme, and a few opportunities for showers and thunderstorms, especially July 30-31 as an old frontal boundary gets close to the region before washing out. This pattern will be driven by a ridge of high pressure out West, a weaker one off the East Coast, and a northward-displaced jet stream with a weak mean trough in the Upper Midwest to Great Lakes.

DAYS 11-15 (AUGUST 4-8)
A stronger front may cross the region August 4 or August 5 as the trough in the Upper Midwest gets a shot of energy from a Canadian disturbance and makes a run into the Northeast. This may set up a more seasonable temperature pattern but also provide greater opportunity for another round of showers/storms later in the period.

7:12AM

COMMENTARY
Warning! Quiet summer pattern ahead! Sorry, I don’t really do “drama” so I was just having a little fun and poking fun at media at the same time. But joking aside, I do want to give a shout out to the National Weather Service Boston for a spectacular job warning and informing those impacted by severe weather in southeastern New England, especially Cape Cod, between Monday night and Tuesday afternoon, as some big storms rolled through the area. There may be some significant damage and power outages, but there were no serious injuries and no lives were lost. Severe weather in a densely populated area during vacation time can have very bad results, and their warnings helped avoid that. Damage will be repaired. Lives can’t be replaced, and they very well may have saved some. Great job NWS!

DAYS 1-5 (JULY 24-28)
So, about that quiet weather. A final wave of low pressure is close enough for a few showers on Nantucket to start the day, otherwise we’ll see a clearing trend as drier air arrives from Canada. High pressure moves into the region by tonight and Thursday then hangs around through the weekend. We will see a gradual warm-up and very slow increase in humidity, which you won’t really notice until sometime over the weekend, but not reaching the levels of last weekend, just more typical for mid summer here in New England.
Forecast details…
TODAY: Early shower Nantucket otherwise clouds give way to sun. Highs 70-77 coast, 77-84 interior. Wind light variable with sea breezes.
TONIGHT: Mostly clear to partly cloudy. Patchy fog possible rural low elevations. Lows 56-63. Wind light variable.
THURSDAY: Mostly sunny to partly cloudy. Highs 78-85, coolest coast. Wind light N with coastal sea breezes.
THURSDAY NIGHT: Mostly clear. Lows 58-65. Wind light variable.
FRIDAY: Mostly sunny. Highs 80-87, coolest coast. Wind light variable with coastal sea breezes.
FRIDAY NIGHT: Mostly clear. Lows 60-67. Wind light S.
SATURDAY: Mostly sunny. Highs 83-90. Wind SW up to 10 MPH.
SATURDAY NIGHT: Mostly clear. Lows 62-69. Wind light SW.
SUNDAY: Mostly sunny. Highs 85-92. Wind SW 5-15 MPH.

DAYS 6-10 (JULY 29-AUGUST 2)
Typical summer pattern to end July and start August, warm to hot, some humidity but not extreme, and a few opportunities for showers and thunderstorms, especially July 30-31 as an old frontal boundary gets close to the region before washing out. This pattern will be driven by a ridge of high pressure out West, a weaker one off the East Coast, and a northward-displaced jet stream with a weak mean trough in the Upper Midwest to Great Lakes.

DAYS 11-15 (AUGUST 3-7)
A stronger front may cross the region August 4 or August 5 as the trough in the Upper Midwest gets a shot of energy from a Canadian disturbance and makes a run into the Northeast. This may set up a more seasonable temperature pattern but also provide greater opportunity for another round of showers/storms later in the period.

7:18AM

DAYS 1-5 (JULY 23-27)
We’re in the midst of an unsettled stretch and getting a decent soaking, which was needed as it had been fairly dry in July so far. Last night the first wave of 3 passed by and maximized its potential with quite a light show and some wind damage along the South Coast, especially parts of Cape Cod, where severe weather is a little more rare than elsewhere in southern New England. NWS will investigate damage to determine if it was straight-line, down burst, or tornado. Moving on, the second wave brings a fairly widespread soaker this morning before it moves off to the east and takes the rain with it this afternoon, although the clouds and cool temperatures with general onshore flow will continue through the day. The third wave of low pressure will bring yet another round of rain into the region, favoring southeastern areas, later tonight and first thing Wednesday, before we finally see a clearing trend as drier air arrives from Canada. High pressure then moves in with fabulous summer weather Thursday through Saturday.
Forecast details…
TODAY: Cloudy with widespread showers and possible embedded thunderstorms this morning. Mostly cloudy with isolated showers this afternoon. Humid. Highs 68-75. Wind NE 5-15 MPH.
TONIGHT: Cloudy. Chance of rain, favoring southern and eastern MA, eastern CT, and RI. Humid. Lows 55-62. Wind light NE.
WEDNESDAY: Mostly cloudy. Chance of rain early, favoring RI and southeastern MA. Drying out. Highs 70-77. Wind NE to N 5-15 MPH.
WEDNESDAY NIGHT: Partly cloudy. Lows 55-62. Wind light NW.
THURSDAY: Mostly sunny to partly cloudy. Highs 80-87 but may cool back to 70s coast. Wind W 5-15 MPH but coastal sea breezes possible.
THURSDAY NIGHT: Mostly clear. Lows 60-67. Wind light variable.
FRIDAY: Mostly sunny. Highs 82-89 but a little cooler coast. Wind light variable with sea breezes.
FRIDAY NIGHT: Mostly clear. Lows 62-69. Wind light SW.
SATURDAY: Mostly sunny. Highs 83-90. Wind SW 5-15 MPH.

DAYS 6-10 (JULY 28-AUGUST 1)
High pressure brings fair and warm to hot, more humid weather July 28. A front gets close and gradually washes out in the region with very warm, somewhat humid weather July 29-31 along with a risk of a few showers and thunderstorms popping up at least a couple of those days. Jet stream lifts north with more heat/humidity to start August.

DAYS 11-15 (AUGUST 2-6)
Jet stream to north, flat ridge to south and southwest, a recipe for hot, humid early August weather with limited thunderstorm chances. A front may get closer later in the period to increase the thunderstorm risk.

7:06AM

DAYS 1-5 (JULY 22-26)
The heat’s gone, and the humidity is down a couple notches, although technically it will still be humid early this week. We don’t get a true push of dry Canadian air until the 3rd of 3 wave of low pressure ride along a front just to the south of the region, and that won’t happen until Wednesday. We basically get one a day for the next 3 days, the first bringing a fairly widespread area of showers and thunderstorms later today into tonight, the second bringing another round favoring areas a little further south in MA/CT/RI Tuesday, and the third keeping the wet weather mainly to the south except possibly clipping the islands early Wednesday. It is the first one that will have the greatest impact, with some potential road flooding due to heavier rainfall of up to 2 or 3 inches in a some locations, and the potential for a few embedded strong storms. We’ll now-cast that with radar during the afternoon and evening today. By later in the week, high pressure will be back in control with great summer weather!
Forecast details…
TODAY: Mostly cloudy. Widespread showers and embedded thunderstorms arriving this afternoon, especially Boston to Providence corridor northwestward. Humid. Highs 77-84. Wind variable 5-15 MPH.
TONIGHT: Mostly cloudy. Showers likely. Chance of thunderstorms, with the area sinking to the southeast then diminishing from southwest to northeast later in the evening. Patchy fog. Humid. Lows 60-67. Wind variable 5-15 MPH.
TUESDAY: Mostly cloudy. Showers likely along with a risk of a few thunderstorms, favoring southeastern MA, CT, RI. Humid. Highs 70-77. Wind NE to N 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Less humid. Lows 53-60. Wind N 5-15 MPH.
WEDNESDAY: Partly sunny. Highs 76-83, coolest coast. Wind N 5-15 MPH.
WEDNESDAY NIGHT: Partly cloudy. Lows 58-65. Wind light W.
THURSDAY: Mostly sunny to partly cloudy. Highs 80-87 but may cool back to 70s coast. Wind W 5-15 MPH but coastal sea breezes possible.
THURSDAY NIGHT: Mostly clear. Lows 60-67. Wind light variable.
FRIDAY: Mostly sunny. Highs 82-89 but a little cooler coast. Wind light variable with sea breezes.

DAYS 6-10 (JULY 27-31)
The final 5 days of July will be like … July. Kind of a typical summer pattern. Some heat and humidity builds in when we get to the weekend although at this time it looks like high pressure will keep the chance of thunderstorms away or extremely limited, and we will not likely see heat to the degree we did this past weekend. The last few days of the month, with a weak front in the vicinity, may see more in the way of shower and thunderstorm activity.

DAYS 11-15 (AUGUST 1-5)
Some fairly hot and humid weather looks like it may be in the offing to start August off as the jet stream lifts to the north and a flat ridge of high pressure dominates. We will evaluate the risk for any showers and thunderstorms as these days get closer.

DAYS 1-5 (JULY 21-25)
More hot weather today. In fact a few places may exceed yesterday’s heat but a little bit with more of a westerly air flow and a slight drying out of the air mass. But the heat is not going to be long-lived. Having only arrived on Friday it’s ready to make its exit tonight. Will it break with big thunderstorms? Maybe in a few places, but probably not in many, as only a few scattered ones are expected along and ahead of a cold front which will cross the region during the early hours of Monday. And now to make some adjustments to the forecast. I’ve been playing things optimistic, but there is more and more evidence that we are about to entire a fairly short-lived period of near to below normal temperatures and somewhat unsettled weather. By unsettled I don’t necessarily mean days of rain, but rather days where cloudiness will be more prevalent and the chance of some wet weather will be around. The front that comes through early Monday will never really move that far away, and it will allow a couple waves of low pressure to move along it. Right now it looks like the first of them will bring some showery weather late Monday, especially at night, into early Tuesday, before moving away. It’s a second wave that is more uncertain, with some guidance bringing it right in with another round of rainfall on Wednesday, while other guidance keeps it southeast of the region. I’m staying with the keeping it offshore idea for now. By Thursday, weak high pressure should be back with fair weather.

DAYS 6-10 (JULY 26-30)
Weak high pressure controls the weather July 26 with mainly dry weather but we may have to watch a sea breeze boundary for a possible trigger of a shower or thunderstorm. Modified summer heat returns for the July 27-28 weekend, not to the degree of this weekend, with a shower or thunderstorm threat absent on July 27 but likely present on July 28 with a front moving into the area. This front will likely wash out but may still possibly trigger a shower or thunderstorm with seasonable heat and humidity around for July 29-30.

DAYS 11-15 (JULY 31-AUGUST 4)
Seasonable warmth and a risk of a few showers/thunderstorms July 31. Summer heat may return for the first few days of August with limited shower/thunderstorm chances.

DAYS 1-5 (JULY 20-24)
Sparing you a long discussion today and putting a short summary in this place instead. You know all about the weekend heat, and here it is. All that’s left is to see what the numbers turn out to be. Besides the usual cautions with heat, we’ll watch for thunderstorms later Sunday afternoon and evening as a cold front approaches. It’s not a great set-up for severe weather here but any time you have storms breaking heat there is always the chance of at least an isolated one may contain severe weather. It looks like the front will move far enough south to easily break the heat by Monday, but a wave of low pressure on it will bring unsettled weather later Monday into at least early Tuesday. How deep into Tuesday it stays that way will depend on the speed of the low pressure area and how quickly it can pull the front back to the south after rippling it back to the north Monday night and early Tuesday. Once we get to Wednesday, we’re back in the dry air, but fairly refreshing air from Canada. We may have to watch for some pop up clouds due to colder air above after the sun heats the ground and sends thermals skyward. Not sure if this can develop any showers yet but will watch it.
