6:53AM

DAYS 1-5 (JULY 16-20)
Humidity remains high early this week and as fog and low clouds burn off and sun heats the land today a few showers/storms may pop up. Showers/storms will be more widespread later Tuesday with the help of a cold front which will deliver drier air to the region at midweek. Forecast details…
TODAY: Fog and low clouds burn off then partly to mostly sunny by midday into afternoon when isolated showers/thunderstorms will pop up.
Humid. Highs 78-85 coast, 85-92 interior. Wind light variable with coastal sea breezes developing.
TONIGHT: Partly to mostly cloudy. Areas of fog. Humid. Lows 64-72. Wind light S.
TUESDAY: Partly to mostly cloudy. Areas of fog early. Showers and thunderstorms likely from mid afternoon on from west to east. Humid. Highs 75-82 coast, 82-88 interior. Wind SW 5-15 MPH but may be variable and gusty near any storms.
TUESDAY NIGHT: Mostly cloudy. Showers and thunderstorms likely through late evening, especially eastern and southern NH/MA and eastern CT to RI. Areas of fog. Humid. Lows 62-69. Wind light variable but may be gusty near any storms early, then N up to 10 MPH overnight.
WEDNESDAY: Mostly cloudy morning with possible showers, especially Cape Cod, then clearing. Less humid. Highs 75-82. Wind N 5-15 MPH.
THURSDAY: Mostly sunny. Lows in the 60s. Highs from the upper 70s to middle 80s.
FRIDAY: Mostly sunny. Lows in the 60s. Highs in the 80s but cooler some coastal areas.

DAYS 6-10 (JULY 21-25)
The weekend of July 21-22 should feature only isolated thunderstorms Saturday but a better opportunity for showers/storms during Sunday. Into next week, a pattern transition to ridge West, trough Midwest / Great Lakes, ridge off East Coast will be underway with higher humidity common, warm to at times hot, but almost daily opportunities for at least isolated showers and thunderstorms.

DAYS 11-15 (JULY 26-30)
The pattern that develops during the days before this likely continues during this period.

8:21AM

DAYS 1-5 (JULY 15-19)
A few changes today, i.e., the warm front never really gets through and the entire system washes out upon us, but still gets its cold front kind-of-sort-of through. It’s like the “mush pattern”, nothing really clear cut. This is why behind it all we stay humid Monday and there will still be a shower and thunderstorm risk, albeit fairly minor regionwide. Still expecting a stronger front to approach Tuesday with a better chance of showers/storms, clearing out of the region during Wednesday, although the speed of this clearing is somewhat in question. By Thursday, anyway, it should be fair with high pressure in control … maybe. 😉 Forecast details (as best as I can detail them)…
TODAY: Variably cloudy. Areas of light fog early. Isolated showers and thunderstorms. Humid. Highs 76-82 coast, 82-87 interior. Wind light variable.
TONIGHT: Variably cloudy. Areas of fog. Isolated showers early. Humid. Lows 62-67. Wind light variable.
MONDAY: Partly sunny. Isolated showers and thunderstorms midday and afternoon. Humid. Highs 77-83 coast, 83-89 interior. Wind light variable with coastal sea breezes developing.
MONDAY NIGHT: Partly to mostly cloudy. Patchy fog. Humid. Lows 62-69. Wind light S.
TUESDAY: Mostly cloudy. Showers and thunderstorms likely. Areas of fog. Humid. Highs 75-80 coast, 80-85 interior. Wind SW 5-15 MPH.
WEDNESDAY: Mostly cloudy. Chance of showers, especially morning. Humid. Lows in the 60s. Highs in the 70s.
THURSDAY: Mostly sunny. Less humid. Lows in the 60s. Highs from the upper 70s to middle 80s.

DAYS 6-10 (JULY 20-24)
Pattern transition to ridge West, trough Midwest / Great Lakes, ridge off East Coast begins. Higher humidity common, warm to at times hot, but almost daily opportunities for at least isolated showers and thunderstorms.

DAYS 11-15 (JULY 25-29)
The pattern that develops during the days before this likely becomes more established during this period.

10:31AM

DAYS 1-5 (JULY 14-18)
Just a quick later-than-usual update today. Warm front approaches today, passes tonight, followed by a cold front Sunday. Not looking for widespread showers/storms with either, and they will favor areas to the west and southwest of Boston. Sunday’s activity may be helped by a South Coast sea breeze boundary as well. Next round of showers/storms is due Tuesday to early Wednesday from a stronger front bumping into warm/humid air in place. Forecast details…
TODAY: Partly sunny. Highs 73-78 coast, 78-83 interior. Wind SE 5-15 MPH.
TONIGHT: Mostly cloudy. Scattered showers and a slight chance of thunderstorms. Lows 61-68. Wind SE 5-15 MPH shifting to SW.
SUNDAY: Variably cloudy. Isolated to scattered showers and thunderstorms. Highs 75-80 coast, 80-85 interior. Wind SW to W 5-15 MPH.
MONDAY: Partly cloudy. Lows in the 60s. Highs in the 80s except some 70s South Coast.
TUESDAY: Variably cloudy. Chance of showers/thunderstorms, especially afternoon and night. Lows in the 60s. Highs in the 80s except some 70s South Coast.
WEDNESDAY: Variably cloudy. Chance of showers, mainly in the morning. Lows in the 60s. Highs from the upper 70s to middle 80s.

DAYS 6-10 (JULY 19-23)
Fair and pleasant July 19. Humidity increases as does the possibility of showers and thunderstorms during the remainder of the period, but don’t read this as a wet pattern, just more of typical summertime.

DAYS 11-15 (JULY 24-28)
Large scale pattern will feature high pressure ridge western US, low pressure trough upper Midwest to Great Lakes, and high pressure over the western Atlantic. This pattern, though not too wet, is not absent of shower and thunderstorm opportunities from time to time, along with fairly dominant warm to hot weather and humidity.

7:09AM

DAYS 1-5 (JULY 13-17)
High pressure keeps control today then gives it up this weekend as a disturbance sends a warm front toward the region Saturday, passing through from west to east at night, then a cold front which drops north to south across the region Sunday. Though no widespread or long-lasting rain is expected, it may be unsettled for part of the weekend with a few showers and thunderstorms any time from late Saturday through Sunday. The cold front that comes through Sunday will not really be followed by much in the way of refreshing air from Canada, as the overall pattern will feature a southwest flow into early next week with warm/humid weather Monday and a shower/thunderstorm threat from another approaching front on Tuesday. Forecast details…
TODAY: Partly cloudy. Highs 73-78 coast, 78-83 interior. Wind SE up to 10 MPH.
TONIGHT: Partly cloudy. Lows 60-67. Wind light SE.
SATURDAY: Partly sunny. Highs 73-78 coast, 78-83 interior. Wind SE 5-15 MPH.
SATURDAY NIGHT: Mostly cloudy. Scattered showers and a slight chance of thunderstorms. Lows 61-68. Wind SE 5-15 MPH shifting to SW.
SUNDAY: Variably cloudy. Isolated to scattered showers and thunderstorms. Highs 75-80 coast, 80-85 interior. Wind SW to W 5-15 MPH.
MONDAY: Partly cloudy. Lows in the 60s. Highs in the 80s except some 70s South Coast.
TUESDAY: Variably cloudy. Chance of showers/thunderstorms, especially afternoon and night. Lows in the 60s. Highs in the 80s except some 70s South Coast.

DAYS 6-10 (JULY 18-22)
Shower threat lingers into July 18 before drying out through July 19. Humidity and shower/thunderstorm threat increases later July 20 through the July 21-22 weekend.

DAYS 11-15 (JULY 23-27)
Large scale pattern will feature high pressure ridge western US, low pressure trough upper Midwest to Great Lakes, and high pressure over the western Atlantic. This pattern, though not too wet, is not absent of shower and thunderstorm opportunities from time to time, along with fairly dominant warmth and humidity.

7:36AM

DAYS 1-5 (JULY 12-16)
Due to time constraints this morning this is essentially yesterday’s blog, slightly updated, but well, there are no changes to the forecast anyway.
TODAY: Sunny to partly cloudy. Slight risk of an isolated shower southeastern NH and eastern MA in the afternoon. Highs 75-80 coast, 80-85 interior. Wind light variable with sea breezes.
TONIGHT: Mostly clear. Lows 56-64. Wind light S to SW.
FRIDAY: Mostly sunny. Highs 78-83 South Coast, 83-88 elsewhere. Wind SW to W 5-15 MPH.
SATURDAY & SUNDAY: Mostly sunny to partly cloudy. Lows in the 60s. Highs from the lower 80s to around 90, coolest coastal areas.
MONDAY: Mostly sunny. Lows in the 60s. Highs from the middle 80s to lower 90s.

DAYS 6-10 (JULY 17-21)
A front will push through the region with higher humidity and a shower/thunderstorm threat July 17 into July 18 before slightly cooler and drier air arrives by July 19 but may be short lived as warm air tries to make a come back by the end of the period, possibly with some unsettled weather during the process.

DAYS 11-15 (JULY 22-26)
A little uncertainty on the exact evolution of the pattern as we will see the pattern of ridge western US, broad trough eastern Canada to Great Lakes and New England trying to hold on while high pressure also tries to build off the US East Coast. Best way to describe resulting weather would be changeable, warm and humid overall, and a few opportunities for showers and thunderstorms. Will fine-tune going forward.

7:00AM

DAYS 1-5 (JULY 11-15)
A bit of a natural light show in the early morning hours over much of the region, and a bit more than just a light show if you were from about Boston’s Metro West to the city and southward as some thunderstorms did indeed develop and took their time moving through. This was in response to the impulse of energy moving through the region, mentioned in yesterday’s comments section. It took its time moving through too, prolonging the show somewhat. But now the front is through and other than a few lingering showers early today in southeastern areas, drier and cooler air moves in but on a northeast breeze so it will feel especially cool near the coast, especially east and north facing shores. High pressure dominates the region through the end of this week, cresting overhead and allowing for sea breezes on Thursday. These will trigger some clouds and perhaps an isolated shower in an otherwise dry day. Expect a warming trend as high pressure sinks to the south Friday through the weekend. Still leaving the shower threat out of the forecast for the coming weekend. Forecast details…
TODAY: Variably cloudy with isolated showers southeastern MA and southern RI through late morning followed by clearing. Mostly sunny elsewhere. Highs 73-78 eastern coastal areas and Cape Cod, 78-83 elsewhere. Wind NE 5-15 MPH.
TONIGHT: Clear. Patchy fog interior low lying locations. Lows 52-57 interior lowlands, 56-62 elsewhere. Wind light variable.
THURSDAY: Sunny to partly cloudy. Slight risk of an isolated shower southeastern NH and eastern MA in the afternoon. Highs 75-80 coast, 80-85 interior. Wind light variable with sea breezes.
THURSDAY NIGHT: Mostly clear. Lows 56-64. Wind light S to SW.
FRIDAY: Mostly sunny. Highs 78-83 South Coast, 83-88 elsewhere. Wind SW to W 5-15 MPH.
SATURDAY & SUNDAY: Mostly sunny to partly cloudy. Lows in the 60s. Highs from the lower 80s to around 90, coolest coastal areas.

DAYS 6-10 (JULY 16-20)
Dry and very warm to hot July 16. A front will push through the region with higher humidity and a shower/thunderstorm threat July 17 into July 18 before slightly cooler and drier air arrives by July 19 but may be short lived as warm air tries to make a come back by the end of the period, possibly with some unsettled weather during the process.

DAYS 11-15 (JULY 21-25)
A little uncertainty on the exact evolution of the pattern as we will see the pattern of ridge western US, broad trough eastern Canada to Great Lakes and New England trying to hold on while high pressure also tries to build off the US East Coast. Best way to describe resulting weather would be changeable, warm and humid overall, and a few opportunities for showers and thunderstorms. Will fine-tune going forward.

7:10AM

DAYS 1-5 (JULY 10-14)
We are now at the start of the middle of the middle of Meteorological Summer, which is a fancy way of saying July 10. But regardless of how you say it, the weather is pretty easy to describe today and can be done so with 2 words: sunny, hot. This weather will be achieved as high pressure sinks to the south of the region, but it’s really only a one-day blast of heat with a bit humidity thrown in, as a cold front dropping down from northern New England will put a quick end do it as it goes by the region tonight. The front is not accompanied by a tremendous amount of storm support, so not looking for any widespread rain/storms, however a few showers and thunderstorms will pop up along the front this afternoon to the north of this area, and some will stray into southern New England this evening and early tonight. High pressure builds in from eastern Canada with cooler air for Wednesday and Thursday. However clouds and a shower threat may linger over the South Coast and Cape Cod through midday Wednesday. In additional, there may be just enough lift from a sea breeze boundary to pop a shower just back from the eastern coastal areas Thursday afternoon, otherwise dry weather is expected during midweek. Forecast Hurricane Chris will pass out to sea to the southeast of New England after all, but will create some increased seas and coastal surf in the area later this week. High pressure sinks to the south but maintains control late in the week, when it will heat up a little more, though the high humidity will be kept at bay. Forecast details…
TODAY: Sunny through afternoon then increasing clouds north to south evening. More humid. Highs 83-88 South Coast and Cape Cod, 88-95 elsewhere. Wind W 5-15 MPH.
TONIGHT: Variably cloudy. Isolated showers and thunderstorms from north to south. Humid early, then drying. Lows 62-68. Wind shifting to N 5-15 MPH.
WEDNESDAY: Variably cloudy with isolated showers South Coast through midday then clearing. Mostly sunny elsewhere. Highs 73-78 eastern coastal areas and Cape Cod, 78-83 elsewhere. Wind NE 5-15 MPH.
WEDNESDAY NIGHT: Clear. Patchy fog interior low lying locations. Lows 53-58 interior lowlands, 58-63 elsewhere. Wind light variable.
THURSDAY: Sunny to partly cloudy. Slight risk of an isolated shower southeastern NH and eastern MA in the afternoon. Highs 75-80 coast, 80-85 interior. Wind light variable with sea breezes.
FRIDAY: Mostly sunny. Lows from the upper 50s to middle 60s. Highs in the 80s.
SATURDAY: Mostly sunny. Lows in the 60s. Highs from the lower 80s to around 90, coolest coastal areas.

DAYS 6-10 (JULY 15-19)
Warmer to hot, a bit more humid, but dry weather July 15-16. Showers/thunderstorms July 17 with high humidity leading to a cooling and drying trend by the middle of next week as another trough drops out of Canada.

DAYS 11-15 (JULY 20-24)
The pattern we’re currently in and expected to be in for the coming 10 days may repeat in a weaker fashion here as high pressure tries to build off the Atlantic Coast. Low confidence forecast at this time.

6:55AM

DAYS 1-5 (JULY 9-13)
High pressure sinks to the south of the region and allows heat into the region early this week, but still dry today before some humidity increase Tuesday, though neither heat nor humidity will be to the level of what was seen last week. A cold front will cross the region Tuesday night and ahead of it a few showers or thunderstorms are possible from late Tuesday afternoon to the early hours of Wednesday. High pressure builds in at midweek and not only will bring drier and somewhat cooler air, but should play a role in keeping Chris, forecast to be a hurricane, mainly offshore. Leaning a little more to this being the case rather than the sneaker closer pass, but leaving showers in the forecast for Cape Cod Thursday just in case. High pressure moves over then south of the region Friday, which will end up a warmer day. Forecast details…
TODAY: Sunny. Highs 78-85 South Coast, 86-93 elsewhere. Wind W 5-15 MPH.
TONIGHT: Mostly clear. Lows 60-67. Wind SW up to 10 MPH.
TUESDAY: Partly cloudy. Isolated thunderstorms possible far north and west of Boston by late day. More humid. Highs 78-85 South Coast, 86-93 elsewhere. Wind SW 5-15 MPH.
TUESDAY NIGHT: Variably cloudy. Isolated showers and thunderstorms. Humid. Lows 65-72. Wind SW up to 10 MPH but may be variable and gusty near any storms.
WEDNESDAY: Mostly sunny. Less humid. Highs 75-83. Wind N 5-15 MPH.
THURSDAY: Partly cloudy. Risk of showers Cape Cod. Lows from the upper 50s to middle 60s. Highs from the upper 70s to middle 80s.
FRIDAY: Mostly sunny. Lows in the 60s. Highs in the 80s, cooler some coastal areas.

DAYS 6-10 (JULY 14-18)
A warm to hot July 14-15 weekend with no more than isolated showers and thunderstorms. A front in the area may trigger additional showers and storms sometime in the July 16-18 period, but most of the time will likely be rain-free with near to above normal temperatures.

DAYS 11-15 (JULY 19-23)
Overall pattern remains warm with a couple shower and thunderstorm threats, but largely dry weather overall.

8:15AM

DAYS 1-5 (JULY 8-12)
Just a quick update today. High pressure maintains control, looking like through Tuesday at this time, and still watching the offshore tropical system during midweek. Odds favor it staying offshore at this point, but need to keep an eye on it, especially Cape Cod. If nothing else, it will be increase the seas in the region.
TODAY: Sunny. Highs 77-85. Wind light variable.
TONIGHT: Clear. Lows 57-64. Wind light SW.
MONDAY: Sunny. Highs 78-85 South Coast, 85-92 elsewhere. Wind W 5-15 MPH.
MONDAY NIGHT: Clear. Lows 60-68. Wind light W.
TUESDAY: Partly cloudy. Highs 78-85 South Coast, 85-92 elsewhere. Wind SW 5-15 MPH.
WEDNESDAY & THURSDAY: Variably cloudy. Possible coastal showers. Lows in the 60s. Highs from the upper 70s to middle 80s.

DAYS 6-10 (JULY 13-17)
Fair early and late period with a shower and thunderstorm threat mid period. Temperatures near to above normal.

DAYS 11-15 (JULY 18-22)
A west to east flow will carry a couple disturbances producing shower and thunderstorm threats in passing, but the overall pattern is on the drier side with near to above normal temperatures.

9:17AM

DAYS 1-5 (JULY 7-11)
Simply beautiful weekend as high pressure dominates, then as it sinks to the south a little summer heat, without humidity arrives Monday. Tuesday-Wednesday we will see warmth and an increase in humidity but have to start watching a tropical system off the East Coast. Though computer guidance currently takes this system offshore, there are some subtle things these models can miss that leave open the door for that system to come closer or even over the region as early as later Tuesday, so the wording for Tuesday and Wednesday in the forecast below will be vague and a little lower confidence than usual for this time period.
TODAY: Sunny. Highs 75-82. Wind NW 5-15 MPH.
TONIGHT: Clear. Lows 55-62. Wind light N.
SUNDAY: Sunny. Highs 77-85. Wind light variable.
SUNDAY NIGHT: Clear. Lows 57-64. Wind light SW.
MONDAY: Sunny. Highs 78-85 South Coast, 85-92 elsewhere. Wind W 5-15 MPH.
TUESDAY: Increasing clouds. Chance of showers or rain at night. Lows in the 60s. Highs in the 80s.
WEDNESDAY: Mostly cloudy with a chance of rain or showers early, then partly cloudy. Lows in the 60s. Highs from the upper 70s to middle 80s.

DAYS 6-10 (JULY 12-16)
Shower threat early in the period from nearby tropical moisture. Jet stream systems bring shower and thunderstorm threats around July 13 and 16. Temperatures near to above normal.

DAYS 11-15 (JULY 17-21)
A west to east flow will carry a couple disturbances producing shower and thunderstorm threats in passing, but the overall pattern is on the drier side with near to above normal temperatures.

7:15AM

DAYS 1-5 (JULY 6-10)
Trough passes through this morning followed by a cold front midday and afternoon. Most of the moisture and energy for showers and thunderstorms is with the trough with less available for the front so the majority of the activity should be taking place before noon for a good portion of the region but will take until mid afternoon to pass through all of the southeastern areas before exiting. This marks an end to the current spell of heat and humidity and will be followed by a refreshing air mass through the weekend. Some heat returns early next week but without humidity getting all that high, though it will be a little more humid by Tuesday. Forecast details…
TODAY: Variably cloudy. Areas of showers and thunderstorms favoring areas west and north of Boston through midday and south of Boston into the afternoon. A few storms may be strong. Humid. Highs 78-86. Wind SW 10-20 MPH shifting to NW from north to south during the day.
TONIGHT: Clearing. Drier. Lows 56-64. Wind NW 5-15 MPH.
SATURDAY: Sunny to partly cloudy. Highs 75-82. Wind NW 5-15 MPH.
SATURDAY NIGHT: Mostly clear. Lows 55-62. Wind light N.
SUNDAY: Sunny. Highs 77-85. Wind light variable.
MONDAY: Sunny. Lows from the upper 50s to middle 60s. Highs in the 80s.
TUESDAY: Partly cloudy. Lows in the 60s. Highs in the 80s.

DAYS 6-10 (JULY 11-15)
A series of disturbances will battle what wants to be the return of heat and this will bring a few opportunities for showers and thunderstorms with variable but near seasonable temperatures overall.

DAYS 11-15 (JULY 16-20)
A bit of settling but overall the same pattern continues with a couple shower and thunderstorm opportunities but variable but overall seasonable to slightly above normal temperatures.

9:49AM

DAYS 1-5 (JULY 5-9)
One more day of full heat under a ridge of high pressure before a cold front slices through the region and puts an end to it. The timing of this front is critical in determining the strength of thunderstorms. There are also a couple of troughs on either side of it, so more than one wave of storms is possible. It does look like the timing will be early enough to prevent maximum storm potential at least north and west of Boston. If enough sun is present south of Boston, where the front doesn’t get there quite as early, there may be some stronger storms. Some of the short range guidance has also shown a second area of storms north of Boston early to mid afternoon so while I may not fully buy this, it’s not being dismissed outright either. Regardless, by the evening, the front will be through the region and a refreshing air mass will be inbound, and ready to provide a very comfortable weekend. By Monday, we’ll already be into a new warm up, but not seeing signs of the same level of heat we’re currently experiencing. Forecast details…
TODAY: Sunny. Humid. Highs 82-89 South Coast, 90-98 elsewhere. Wind SW 5-15 MPH.
TONIGHT: Partly cloudy. Humid. Lows 68-77, warmest urban areas. Wind SW 5-15 MPH.F
FRIDAY: Variably cloudy. Areas of showers and thunderstorms favoring areas west and north of Boston through midday and south of Boston into the afternoon. A few storms may be strong. Humid. Highs 78-86. Wind SW 10-20 MPH shifting to NW from north to south during the day.
FRIDAY NIGHT: Clearing. Drier. Lows 56-64.Wind NW 5-15 MPH.
SATURDAY: Sunny to partly cloudy. Highs 77-85. Wind NW 5-15 MPH.
SUNDAY: Sunny. Lows from the middle 50s to lower 60s. Highs from the upper 70s to middle 80s.
MONDAY: Sunny. Lows from the upper 50s to middle 60s. Highs in the 80s.

DAYS 6-10 (JULY 10-14)
A series of disturbances will battle what wants to be the return of heat and this will bring a few opportunities for showers and thunderstorms with variable but near seasonable temperatures overall.

DAYS 11-15 (JULY 15-19)
A bit of settling but overall the same pattern continues with a couple shower and thunderstorm opportunities but variable but overall seasonable to slightly above normal temperatures.

6:36AM

DAYS 1-5 (JULY 4-8)
Hot ridge continues to dominate on this Independence Day and will do so through tomorrow before relaxing is grip and heading westward to some degree late in the week, allowing a trough to dip out of Canada. There are no significant changes to this forecast which will pretty much look like an update of the previous. Still have to work out Friday’s timing to determine the coverage and intensity of thunderstorms. Before that, we will see a few more pop up storms today, in 2 rounds, but more isolated than yesterday and this time mainly to the south. Forecast details…
TODAY – INDEPENDENCE DAY: Areas of fog early. Partly cloudy to mostly sunny. Isolated showers and thunderstorms in southeastern MA, RI, and southeastern CT by mid morning, then another round of isolated storms in similar locations to as far north as the Mass Pike area this afternoon. Humid. Highs 78-86 immediate shorelines and Cape Cod, 87-96 elsewhere, hottest interior valleys. Wind light variable with light coastal sea breezes.
TONIGHT: Mostly clear. Humid. Lows 67-77, warmest in urban areas. Wind light variable.
THURSDAY: Mostly sunny. Humid. Highs 80-88 South Coast, 88-97 elsewhere, hottest interior valleys. Wind W up to 10 MPH.
FRIDAY: Partly sunny. Thunderstorms likely, favoring the afternoon and evening. Humid. Lows from the upper 60s to middle 70s. Highs from the middle 80s to middle 90s.
SATURDAY: Partly cloudy. Less humid. Lows in the 60s. Highs from the upper 70s to middle 80s.
SUNDAY: Mostly sunny. Lows from the upper 50s to middle 60s. Highs from the upper 70s to middle 80s.

DAYS 6-10 (JULY 9-13)
Dry and seasonably warm July 9. Showers/thunderstorms possible with a passing disturbance July 10 and watching another for late in the period with fair weather in between.

DAYS 11-15 (JULY 14-18)
A couple passing disturbances bring changeable but overall seasonable temperatures and a couple thunderstorm threats during this period.

7:05AM

DAYS 1-5 (JULY 3-7)
High pressure ridge dominates with hot weather into Friday. Air mass pop up thunderstorms are possible but only in isolated locations favoring west and northwest of Boston later today, and mainly west and south of Boston on Wednesday. The next thunderstorm threat will come in a more widespread way during Friday afternoon and evening as a cold front moves through the region. This will bring cooler and drier weather for the area by Saturday. Forecast details…
TODAY: Mostly sunny to partly cloudy. Slight chance of isolated thunderstorms late afternoon mainly southwestern NH and central MA. Humid. Highs 80-89 immediate South Coast and Cape Cod, 90-98 elsewhere, hottest interior valleys. Wind SW 5-15 MPH.
TONIGHT: Partly cloudy to mostly clear. Humid. Lows 65-75, warmest urban centers. Wind light variable.
WEDNESDAY – INDEPENDENCE DAY: Mostly sunny to partly cloudy. Isolated afternoon thunderstorms possible, central and southeastern MA, northern RI, and northeastern CT. Humid. Highs 78-86 immediate shorelines and Cape Cod, 87-96 elsewhere, hottest interior valleys. Wind light variable with light coastal sea breezes.
WEDNESDAY NIGHT: Mostly clear. Humid. Lows 67-77, warmest in urban areas. Wind light variable.
THURSDAY: Mostly sunny. Humid. Highs 80-88 South Coast, 88-97 elsewhere, hottest interior valleys. Wind W up to 10 MPH.

SATURDAY: Partly cloudy. Less humid. Lows in the 60s. Highs from the upper 70s to middle 80s.

DAYS 6-10 (JULY 8-12)
July 8-9 look dry and seasonably warm. A disturbance coming along the jet stream brings a shower/thunderstorm threat July 10-11. Fair weather returns to end the period.

DAYS 11-15 (JULY 13-17)
A couple passing disturbances bring changeable but overall seasonable temperatures and a couple thunderstorm threats during this period.

8:46AM

DAYS 1-5 (JULY 2-6)
A modified batch of marine air sits over the region to start today and will be eroded and transformed to become part of the hot air mass under the high pressure ridge in the eastern US. This will take place during today and be in full force by tomorrow, and the heat will be in full control through midweek, save for a few coastal sea breezes. The only rain chance would be an isolated pop up air mass thunderstorm late Tuesday and sometime Wednesday afternoon, and these would favor interior locations. Thursday looks too stable to support any of these. However, something will be going on to our north on Thursday, the only visual evidence we will probably see of it will be some cloud patches in the northwest and north sky late in the day, from thunderstorms that erupted ahead of a cold front moving in from Canada. This front will proceed southeastward and bring thunderstorms to this area during Friday (timing to be figured out). Forecast details…
TODAY: Mostly sunny. Humid. Highs 77-85 immediate shore, 86-94 interior. Wind light E to SE becoming S late.78-86 immediate South Coast and Cape Cod, 87-96 elsewhere, hottest interior valleys.
TONIGHT: Mostly clear. Humid. Lows 64-72. Wind light S to SW.
TUESDAY: Mostly sunny to partly cloudy. Slight chance of isolated thunderstorms late afternoon mainly southwestern NH and central MA. Humid. Highs 80-89 immediate South Coast and Cape Cod, 90-98 elsewhere, hottest interior valleys. Wind SW 5-15 MPH.
TUESDAY NIGHT: Partly cloudy to mostly clear. Humid. Lows 65-75, warmest urban centers. Wind light variable.
WEDNESDAY – INDEPENDENCE DAY: Mostly sunny to partly cloudy. Isolated afternoon thunderstorms possible, mainly southwestern NH, central MA, northern RI, and northeastern CT. Humid. Highs 78-86 immediate shorelines and Cape Cod, 87-96 elsewhere, hottest interior valleys. Wind light variable with light coastal sea breezes.
THURSDAY: Mostly sunny. Humid. Lows from the upper 60s to upper 70s. Highs from the upper 80s to upper 90s but cooler in some coastal areas.
