7:56AM

DAYS 1-5 (JULY 6-10)
Typical summertime pattern for New England. Heat and humidity today, add an approaching cold front and create a threat of thunderstorms, some of which could be strong. Will be monitoring radar through the day. Threat diminishes northwest to southeast as the front passes this evening. The front will still be close enough for early clouds and a South Coast shower threat Sunday but the trend will be to clear as we will then have an air mass much cooler and drier than the one we’re in now. High pressure brings great summer weather Monday to Wednesday, starting out pleasantly warm and dry then turning a little hotter but only slightly more humid toward midweek.
Forecast details…
TODAY: Partly sunny. Isolated to scattered thunderstorms after 3PM west and north of Boston, mostly after 5PM to the south. Humid. Highs 81-88 Cape Cod and immediate South Coast, 88-95 elsewhere. Wind SW 5-15 MPH, higher gusts.
TONIGHT: Variably cloudy. Scattered to numerous showers and thunderstorms with the threat diminishing from northwest to southeast. Any storms may be strong. Patchy fog overnight. Humid. Lows 66-73. Wind variable 5-15 MPH, higher gusts near storms, shifting to N.
SUNDAY: Mostly cloudy to partly sunny morning with a risk of a shower South Coast. Clearing midday-afternoon. Less humid. Highs 75-82. Wind N to NE 5-15 MPH with higher gusts.
SUNDAY NIGHT: Clear. Lows 55-62. Wind N 5-15 MPH.
MONDAY: Sunny. Highs 77-84. Wind light variable with coastal sea breezes.

DAYS 6-10 (JULY 11-15)
Overall west to east jet stream pattern. More humid with a risk of mainly afternoon showers/thunderstorms July 11 with an approaching cold front. Less humid with a risk of afternoon showers/thunderstorms July 12 with a secondary trough moving through. High pressure likely brings fair weather for July 13-14 before an approaching warm front brings cloudiness and a risk of showers back to the region to end the period.

DAYS 11-15 (JULY 16-20)
No significant changes to the generally west to east flow, typical summer pattern. Shower and thunderstorm threats early and again later in the period with otherwise mainly dry weather.

7:28AM

DAYS 1-5 (JULY 5-9)
No changes to forecast and a very quick update today. Some heat and humidity today and Saturday, with the shower/thunderstorm threat confined to isolated activity Saturday afternoon and scattered activity Saturday evening as a weak cold front crosses the region, so keep a close eye on the weather if you have outdoor plans Saturday. The front settles to the south but may be close enough to allow a few showers to skirt the South Coast for a time, before high pressure builds in for a pleasant start to next week, dry/mild Monday then quickly warming up Tuesday.
Forecast details…
TODAY: Partly cloudy. Humid. Highs 81-88 coast, 88-95 interior. Wind SW up to 10 MPH but some light coastal sea breezes possible.
TONIGHT: Partly cloudy. Humid. Lows 66-73. Wind SW 5-15 MPH.
SATURDAY: Partly cloudy. Isolated afternoon thunderstorms. Humid. Highs 88-95, cooler Cape Cod. Wind SW 5-15 MPH.

DAYS 6-10 (JULY 10-14)
Overall west to east jet stream pattern. Fair, warming, increasingly humid July 9-10 as a southwesterly surface flow returns. Cold front brings showers/thunderstorms July 11. High pressure returns with fair weather and lower humidity July 12-14.

DAYS 11-15 (JULY 15-19)
Essentially a continuation of the same pattern with the rough timing of the next shower/thunderstorm threat around July 15-16.

6:41AM

DAYS 1-5 (JULY 4-8)
Happy Birthday USA! A typical July summertime pattern will be in place throughout the period, dominated by zonal (west to east) flow of a weak jet stream. A southwesterly surface flow will bring summertime heat and humidity (not extreme) into the region today and Friday, and it will become more humid Saturday ahead of a cold front which will move across the region Saturday night, when the greatest threat of showers and thunderstorms is, although the threat itself may not be all that great. Nevertheless with so many outdoor activities ongoing and still a lot of fireworks displays scheduled for Saturday night, we need to pay attention to that threat, as you don’t need severe storms to result in danger from wind gusts, lightning, flooding, etc. By Sunday, the front will be south of the region and we’ll have turned somewhat cooler and drier, but with some lingering cloudiness and maybe a shower near the South Coast. High pressure builds in with fair weather for Monday.
Forecast details…
TODAY (INDEPENDENCE DAY): Mostly sunny. More humid. Highs 80-87 coast, 87-94 interior. Wind light SW with light coastal sea breezes.

DAYS 6-10 (JULY 9-13)
Overall west to east jet stream pattern. Fair, warming, increasingly humid July 9-10 as a southwesterly surface flow returns. Cold front brings showers/thunderstorms July 11. High pressure returns with fair weather and lower humidity July 12-13.

DAYS 11-15 (JULY 14-18)
Essentially a continuation of the same pattern with the rough timing of the next shower/thunderstorm threat around July 15-16.

8:08AM

DAYS 1-5 (JULY 3-7)
High pressure will dominate the weather the next 3 days with dry weather and a build in heat and some humidity, not to fierce levels by July standards, but you’ll notice it. A cold front will approach Saturday, the most humid day of the next 5, with a shower and thunderstorm threat, and this front will settle to the south of the region Sunday, which will be cooler and less humid but likely with lingering cloudiness and a South Coast shower threat.
Forecast details…
TODAY: Mostly sunny. Highs 81-88, but likely cooling back to upper and middle 70s coast. Wind light variable with light sea breezes.

DAYS 6-10 (JULY 8-12)
Dry and pleasant July 8, quick warm-up July 9, then risk of showers/thunderstorms July 10-11 with a trough and cold front moving through, and a little cooler/drier at the end of the period as high pressure arrives from the west and north.

DAYS 11-15 (JULY 13-17)
A mainly westerly flow with a bit of up and down in the temperatures, no sustained heat, and limited shower/thunderstorm chances, with weather on the drier side the majority of the time.

6:57AM

DAYS 1-5 (JULY 2-6)
A disturbance moves through the region this morning with cloudiness and may even shower for a bit in southern NH and northeastern MA, but that’s gone by afternoon, though clouds may linger to the south a while longer, and it turns quite warm during the day with a west wind. High pressure settles in for Wednesday, a sunnier day start to finish but also with a better chance for coastal sea breezes. High pressure remains in control Thursday (Independence Day) and Friday with increasing heat and humidity, though Thursday may still see light cooling sea breezes right at the beaches. A cold front will approach Saturday, a hotter/humid day, bringing a chance of a few thunderstorms.
Forecast details…

DAYS 6-10 (JULY 7-11)
A weak cold front settles south of the region July 7, a cooler day but some cloudiness lingering with a risk of a shower South Coast. High pressure brings pleasant weather July 8 then moves off for a quick warm up July 9 into 10 with a risk of thunderstorms ahead of a cold front July 10 that should be followed by a push of cooler/drier air to end the period.

DAYS 11-15 (JULY 12-16)
A mainly westerly flow with a bit of up and down in the temperatures, no sustained heat, and limited shower/thunderstorm chances, with weather on the drier side the majority of the time.

8:00AM

DAYS 1-5 (JULY 1-5)
If you picked this week for not having to go to work, you win. Hmm, looks like I won. 😉 … High pressure dominates with about as great a 5-day stretch of weather as you can have, starting out dry and pleasant today with a gradual increase in humidity and a bit more heat as the week goes on, but you will never really feel the humidity become oppressive, because it won’t quite make it to that level, it will just become more noticeable especially by Thursday (July 4). Our fairly insignificant threats of any unsettled weather are in the form of a pop up shower over the hills north and west of Boston later today, a possible early morning shower Tuesday with a passing disturbance, a slight risk of a brief shower early Wednesday south and west of Boston as debris from day-before thunderstorms in the Midwest passes by, and a risk of an air mass thunderstorm popping up later Friday. Otherwise, the next 5 days will be largely rain-free. As a friendly reminder, if
you have outdoor plans, remember things like sunscreen and to drink water for hydration, insect repellent, and as always, check for ticks if you’ve been near any vegetation. Common sense stuff in general but easy to overlook if you are busy coordinating things. Otherwise, enjoy the weather if you have an opportunity to do that!
Forecast details…
TODAY: Sunny to partly cloudy. Highs 77-84. Wind N 5-15 MPH.
TONIGHT: Partly cloudy. Slight risk of a passing shower. Lows 61-68. Wind W 5-15 MPH.
TUESDAY: Clouds early, then mostly sunny. Highs 80-87. Wind W 5-15 MPH.
TUESDAY NIGHT: Mostly clear. Lows 60-67. Wind light W.
WEDNESDAY: Mostly sunny. Highs 82-89, but may cool back to upper 70s coast. Wind light variable with light sea breezes possible.
WEDNESDAY NIGHT: Partly cloudy. Lows 63-70. Wind light variable to SW.
THURSDAY (INDEPENDENCE DAY): Partly cloudy. More humid. Highs 84-91, may turn cooler coast. Wind light SW but coastal sea breezes.
THURSDAY NIGHT: Mostly clear. Humid. Lows 64-71. Wind light SW.
FRIDAY: Partly cloudy. Slight risk of an isolated afternoon thunderstorm. Humid. Highs 85-92. Wind SW 5-15 MPH.

DAYS 6-10 (JULY 6-10)
A weak cold front will cross the region Saturday July 6 which will be a warm to hot, humid day, with a risk of a few showers and thunderstorms. This front drops south of the region Sunday July 7 which will be slightly less humid but still on the warm side with some cloudiness and a risk of South Coast showers. A few changes for early next week with high pressure bringing dry and pleasant weather to start the week then a quick warm up ahead of an approaching front with increasing humidity and a risk of showers/thunderstorms toward midweek.

DAYS 11-15 (JULY 11-15)
A return to mainly westerly flow and seasonably warm weather with a couple disturbances bringing opportunities for passing showers/storms amidst mostly dry weather otherwise. A fairly typical July pattern but we will lack sustained heat in this pattern.

1:47PM

DAYS 1-5 (JUNE 30-JULY 4)
This final day of June will be similar to last Saturday (June 22) as a cold pool of air aloft ignites some instability showers/t-storms. Not everybody will see one, but those that do can experience downpours, lightning, and even small hail. Activity will diminish by evening. Drier, cooler air moves in tonight and Monday will start July off on a very nice note with low humidity and pleasantly warm air but with a cooling breeze. A weak disturbance moves through in the early hours of Tuesday with a shower threat, but the daylight of Tuesday as well as the entirety of Wednesday and Thursday (which is July 4), should be dry and warm with moderate humidity to borderline muggy air, but not excessively hot, just on the warm side of normal. This is generally great for those who have the week off from work with a lot of outside plans, not that I’m talking about myself or anything…haha!
Forecast details…
TODAY: Variably cloudy. Scattered to isolated showers/thunderstorms. Any storms may contain small hail. Highs 75-82. Wind W 5-15 MPH shifting to N, with some higher gusts.
TONIGHT: Clearing. Lows 53-60. Wind N 5-15 MPH.
MONDAY: Sunny to partly cloudy. Highs 75-82. Wind N 5-15 MPH.
MONDAY NIGHT: Partly to mostly cloudy. Risk of a passing shower or thunderstorm. Lows 60-67. Wind W 5-15 MPH.
TUESDAY: Clouds early, then mostly sunny. Highs 78-85. Wind W 5-15 MPH.
TUESDAY NIGHT: Mostly clear. Lows 58-65. Wind light W.
WEDNESDAY: Mostly sunny. Highs 80-87, but may cool back to 70s coast. Wind light variable with light sea breezes possible.
WEDNESDAY NIGHT: Partly cloudy. Lows 62-69. Wind light variable to SW.
THURSDAY (INDEPENDENCE DAY): Partly cloudy. Highs 83-90, may turn cooler coast. Wind light SW but coastal sea breezes.

DAYS 6-10 (JULY 5-9)
Mainly dry July 5, isolated showers/storms July 6 and scattered showers/storms July 7 as a trough approaches from Canada. Temperatures on the warmer side of normal. July 8-9 turn cooler with a risk of some instability shower/storms but more dry time than not.

DAYS 11-15 (JULY 10-14)
A return to mainly westerly flow and seasonably warm weather with a couple disturbances bringing opportunities for passing showers/storms amidst mostly dry weather otherwise.

10:35AM

DAYS 1-5 (JUNE 29-JULY 3)
It’s “go time” on the rough weather threat. Being a little late with this update some of you have already experienced some decent thunderstorms this morning. The first wave activity as generally by the boards but the threat for additional showers/storms, some possibly severe, continues through this afternoon. This is not a case where a widespread line of storms comes through and gets everybody, but there will be smaller line/clusters, probably 1 or 2, left to go during today, and possibly a few more isolated cells as well. So while somebody gets hammered, someone else gets nothing. That’s why it’s important to keep updated on the current weather, not just what your app or TV or WHW says may happen today. Things settle down tonight and then tomorrow, as we have been saying, will be a similar set-up to last Saturday with cold air aloft and pop up showers/storms, main threat being small hail. Not everyone will see these either, but if you happen to get one, you’ll surely know it. And then comes July, and a pleasant/dry start Monday as the low pulls away and high pressure moves in. A disturbance moving rapidly through the region Monday night and early Tuesday may kick off a few showers/storms but it will be mostly dry overall, and then high pressure returns Wednesday with fair weather.
Forecast details…
TODAY: Variably cloudy. Episodes of showers/thunderstorms. While rain-free much of the time in any area, any storms can be strong to severe. Humid. Highs 78-85. Wind variable 5-15 MPH becoming W. Winds can be strong and gusty near storms.
TONIGHT: Partly cloudy. Patchy fog. Humid. Lows 60-67. Wind W 5-15 MPH.
SUNDAY: Partly sunny. Scattered showers/thunderstorms morning-midday. Isolated showers/thunderstorms thereafter. Less humid. Highs 76-83. Wind W 5-15 MPH shifting to N.
SUNDAY NIGHT: Mostly clear. Lows 53-60. Wind N up to 10 MPH.
MONDAY: Sunny to partly cloudy. Highs 75-82. Wind N 5-15 MPH.
MONDAY NIGHT: Partly to mostly cloudy. Risk of a passing shower or thunderstorm. Lows 60-67. Wind W 5-15 MPH.
TUESDAY: Clouds early, then mostly sunny. Highs 78-85. Wind W 5-15 MPH.
TUESDAY NIGHT: Mostly clear. Lows 58-65. Wind light W.
WEDNESDAY: Mostly sunny. Highs 80-87, but may cool back to 70s coast. Wind light variable with light sea breezes possible.

DAYS 6-10 (JULY 4-8)
The majority of this period will see dry weather, and we’ll only have to watch a couple of generally weak disturbances that may be enough to kick off a passing shower or thunderstorm on the July 6-7 weekend, favoring July 7. Additional showers/storms are possible as an upper low and disturbance drop through the region July 8. Temperatures near to slightly above normal as we see a more predominant westerly flow, but may turn cooler at the end of the period.

DAYS 11-15 (JULY 9-13)
A return to mainly westerly flow and seasonably warm weather with a couple disturbances bringing opportunities for passing showers/storms amidst mostly dry weather otherwise.

7:07AM

DAYS 1-5 (JUNE 28-JULY 2)
High pressure controls today’s weather and while humidity is down a few notches the heat will be up a few, with some 90 degree readings possible for the first time in many locations, including Boston. The weekend is unsettled but again I caution you not to take that to mean a wet weekend. There will be a disturbance passing by during Saturday morning and another one sometime Sunday, probably by early afternoon, while during the 2 days a broad upper level low pressure area dives southeastward out of eastern Canada, passing over and just east of New England. Saturday’s shower/storm threat, more linear or broken linear, will be driven more by a cold front, while Sunday’s activity, more isolated to scattered, will be driven by a trough early and lingering cold air aloft into afternoon (similar to the June 22 event). This low gets east of the region with a pleasant and dry northerly air flow Monday to start July, then a weak trough may bring clouds and a risk of a shower late Monday night / early Tuesday before a warmer westerly air flow takes over.
Forecast details…
TODAY: Partly cloudy. Highs 83-90. Wind W up to 10 MPH.
TONIGHT: Clouding over. Rain or showers possible by dawn. More humid. Lows 60-67. Wind light variable.
SATURDAY: Cloudy with areas of fog and a chance of showers/thunderstorms early, then variably cloudy with a risk of showers and thunderstorms mid morning to early afternoon (mid afternoon Cape Cod), then partly cloudy with isolated showers or thunderstorms possible thereafter. Humid.
Highs 79-86. Wind variable 5-15 MPH becoming W.
SATURDAY NIGHT: Partly cloudy. Patchy fog. Humid. Lows 60-67. Wind W 5-15 MPH.
SUNDAY: Partly sunny. Scattered showers/thunderstorms morning-midday. Isolated showers/thunderstorms thereafter. Less humid. Highs 76-83. Wind W 5-15 MPH shifting to N.
SUNDAY NIGHT: Mostly clear. Lows 53-60. Wind N up to 10 MPH.
MONDAY: Sunny to partly cloudy. Highs 75-82. Wind N 5-15 MPH.
MONDAY NIGHT: Partly to mostly cloudy. Risk of a passing shower. Lows 60-67. Wind W 5-15 MPH.
TUESDAY: Mostly sunny. Highs 78-85. Wind W 5-15 MPH.

DAYS 6-10 (JULY 3-7)
The majority of this period will see dry weather, and we’ll only have to watch a couple of generally weak disturbances that may be enough to kick off a passing shower or thunderstorm on the July 6-7 weekend. Temperatures near to slightly above normal as we see a more predominant westerly flow.

DAYS 11-15 (JULY 8-12)
High pressure ridge backs up a little to allow another eastern Canadian trough to drop into the region early in the period with an increased shower/t-storm threat before a generally westerly flow and seasonably warm pattern returns with mostly dry weather.

7:09AM

DAYS 1-5 (JUNE 27-JULY 1)
The marine layer journeyed a distance into the interior during the night with low clouds and fog, but those will burn off as the late June sun rises above it in the sky later this morning, and the day will turn out decently well, but that boundary of marine air and warmer sun-heated land somewhere in southeastern NH and eastern MA and another boundary near the South Coast will pop some clouds this afternoon. However, with not great support, these clouds will probably never build to the level of releasing any showers. With the possibility so remote, not even going to include in the forecast below. If you see one, feel free to tell me I was wrong. I can take it – hehehe. So this advertised “severe weather outbreak” or whatever some have been hinting it might be for the weekend? Yes we have some unsettled weather on the way, but I hesitate to even use that term as we are actually in for a decent weekend overall – just one in which we’ll have to put up with possibly a few damp hours to start it, and then watch for a few hit & miss type showers/storms. Right now, I think the timing of the main energy areas being earlier Saturday and earlier Sunday may limit the amount of shower and storm development to more isolated than anything, but something we’ll have to fine-tune with the help of short-range guidance going into the weekend. Once we get to Monday, the cool pool that enters the region this weekend, being responsible for the shower threat, will be exiting, but we’ll have a northerly air flow of refreshing air to start the month of July.
Forecast details…
TODAY: Low overcast and areas of fog to start, burning off to sunshine. Some clouds pop up this afternoon. Moderately humid. Highs 75-80 coast, 80-85 interior though cooling is possible this afternoon especially coastline. Wind light variable with sea breezes.

SATURDAY: Cloudy with areas of fog and a chance of rain early, then partly sunny with isolated showers and thunderstorms. Humid. Highs 79-86. Wind variable 5-15 MPH becoming W.
SATURDAY NIGHT: Partly cloudy. Patchy fog. Humid. Lows 60-67. Wind W 5-15 MPH.
SUNDAY: Partly sunny. Isolated showers/thunderstorms, favoring mid morning to early afternoon. Humid, but drying late. Highs 76-83. Wind W 5-15 MPH shifting to N.
SUNDAY NIGHT: Mostly clear. Lows 53-60. Wind N up to 10 MPH.
MONDAY: Sunny to partly cloudy. Highs 75-82. Wind N 5-15 MPH.

DAYS 6-10 (JULY 2-6)
The majority of this period will see dry weather, and we’ll only have to watch a couple of generally weak disturbances that may be enough to kick off a passing shower or thunderstorm. Temperatures near to slightly above normal as we see a more predominant westerly flow.

DAYS 11-15 (JULY 7-11)
A general westerly flow, seasonably warm pattern with a couple opportunities for showers/thunderstorms, but dry weather most of the time.

7:25AM

DAYS 1-5 (JUNE 26-30)
The final 5 days of June will have a bit more summer feel to them overall, but don’t look for a heatwave as we are not in the pattern for it. Do expect higher humidity the next few days in general, probably today being the most humid but Friday ending up as the warmest day. The only weather system of note will be a weak trough that approaches from the west today and passes by early Thursday. This triggers thunderstorms to the west of the region that run out of gas due to lack of support as they head east this evening, and while the dying version may reach the western portions of the WHW forecast area, the eastern areas will never see them. There is a slight risk of a pop up shower over the interior areas on Thursday, and high pressure should exert enough control to eliminate that risk during Friday. For the weekend, this is when things are less clear. What we do know is that one disturbance will pass by sometime Saturday, and a small but potent upper low will drop out of eastern Canada Sunday. Both of these will bring threats for some kind of unsettled weather, and my current leaning is for faster timing of system #1 as a wave of low pressure coming from the Great Lakes, bringing some wet weather late Friday night and early Saturday, then with a lingering trough the potential for some pop up showers and thunderstorms during the day Saturday. Sunday’s event, I’m also leaning toward faster timing, will consist of a lobe of cold air aloft and a surface cold front, both of which will likely help ignite at least scattered showers and thunderstorms, but all of which may be done on the earlier side rather than later. For what it’s worth, 2 of the major medium range models flip flopped on this in the latest runs, with one moving away from this thinking while the other moved toward it. Gotta love models. Will update my thoughts as needed on the weekend situation. For now, at days 4 & 5, the forecast wording will be generalized.
Forecast details…
TODAY: Low overcast and areas of fog to start, burning off to sunshine. Some clouds advance from the west late-day with a shower or thunderstorm possible by evening southwestern NH and central MA. Humid. Highs 77-84. Wind light variable, coastal sea breezes.

DAYS 6-10 (JULY 1-5)
The majority of this period will see dry weather, with weak disturbances around July 3 and 5 bringing a possibility of a shower or thunderstorm. Temperatures start out slightly below normal then warm to generally seasonable levels. No major heat expected.

DAYS 11-15 (JULY 6-10)
A general westerly flow, seasonably warm pattern with a couple opportunities for showers/thunderstorms, but dry weather most of the time.

7:36AM

DAYS 1-5 (JUNE 25-29)
Low pressure tracks eastward across southeastern Canada today bringing a warm front / cold front combo through southeastern New England, producing cloudiness, showers, and possibly a few thunderstorms. There is not much dry air behind the cold front portion of this system, which will be weakening and washing out. A secondary trough will come through the region late Wednesday and early Thursday with a more remote risk of a shower or storm (these will be heavier to the west of southeastern New England late-day Wednesday). High pressure will eliminate the shower/storm threat later Thursday through Friday, but an upper level low dropping southeastward out of eastern Canada will drag a cold front southward across New England Saturday and return a chance of shower/storms to the region.
Forecast details…
TODAY: Clouding up. Episodes of showers. Slight chance of thunderstorms especially late-day. Highs 68-75. Wind SE 5-15 MPH shifting to S.
TONIGHT: Mostly to partly cloudy. Patchy fog. Chance of a shower or thunderstorm early. Humid. Lows 57-64. Wind light SW shifting to W.

SATURDAY: Variably cloudy. Chance of showers/thunderstorms. Highs 81-88. Wind W 10-20 MPH.

DAYS 6-10 (JUNE 30-JULY 4)
Upper level low pressure will track southeastward across New England June 30 though its center will probably pass east of the region, and a westward extension of it will trigger some instability showers/thunderstorms of the scattered variety. Dry weather for much of the July 1-4 period but there may be a few additional showers/storms with a weaker upper low taking a similar track sometime July 3 based on current timing. Temperatures start out the period below normal then return to near normal.

DAYS 11-15 (JULY 5-9)
A general westerly flow, seasonably warm pattern with a couple opportunities for showers/thunderstorms, but dry weather most of the time.

7:14AM

DAYS 1-5 (JUNE 24-28)
High pressure brings fair weather today and allows a decent ocean breeze to develop this afternoon as the inland areas heat up, air rises, and is replaced with cooler, more dense marine air from over the much cooler water. Low pressure tracks eastward across southeastern Canada Tuesday bringing a warm front / cold front combo through southeastern New England, the cloudiest and more unsettled day of this week. Lacking much push, the cold front will fizzle out as it goes through, so our midweek will feature more humidity and a daily risk of a few showers/thunderstorms, especially as another weak disturbance moves through the region later Wednesday to early Thursday. But still cannot rule them out right into Friday as well, though a weak area of high pressure should limit the threat by then.
Forecast details…
TODAY: Mostly sunny. Highs 76-83 but turning cooler, especially coast, this afternoon. Wind light variable becoming E 5-15 MPH.

DAYS 6-10 (JUNE 29-JULY 3)
Upper level low pressure will drop southward out of Canada and bring a cooling trend and a risk of showers / thunderstorms June 29-30 weekend. Overall drier with a slow warm-up as July gets underway as the upper low departs and a westerly flow returns. This westerly flow may contain a disturbance and a shower/storm threat briefly.

DAYS 11-15 (JULY 4-8)
A general westerly flow, seasonably warm pattern with a couple opportunities for showers/thunderstorms, but dry weather most of the time.

11:15AM

DAYS 1-5 (JUNE 23-27)
Apologies for the late update and since there are not many changes this is really just a touch-up of the previous blog post more than anything. We do have high pressure in control now with 2 nice days ahead, then a disturbance moving through from west to east brings unsettled weather Tuesday with a follow up doing the same thing sometime Thursday. The first of the two will likely be the better wet weather producer in terms of coverage, while the second one may be more prone to producing scattered but heavier showers and t-storms.
Forecast details…
TODAY: Mostly sunny. Highs 76-83, coolest coast. Wind light variable with sea breezes.
TONIGHT: Mostly clear. Lows 54-61. Wind light variable.
MONDAY: Mostly sunny. Highs 78-85, cooler some coastal areas. Wind light W but with sea breezes possible.
MONDAY NIGHT: Partly cloudy. Lows 60-67. Wind light S.
TUESDAY: Mostly cloudy. Occasional showers. Risk of a thunderstorm. Highs 73-80. Wind S 5-15 MPH.
TUESDAY NIGHT: Clearing. Less humid. Lows 58-65. Wind W 5-15 mph.
WEDNESDAY: Partly cloudy. Highs 75-82. Wind W 5-15 MPH.
WEDNESDAY NIGHT: Partly cloudy. Lows 58-65. Wind SW 5-15 MPH.
THURSDAY: Partly sunny. Risk of passing showers/thunderstorms. More humid. Highs 77-84. Wind SW 10-20 MPH.

DAYS 6-10 (JUNE 28-JULY 2)
The next frontal passage will be as a trough drops through eastern Canada and skirts eastern New England in a weather pattern that shifts the ridge of high pressure into the Plains and western US. This would bring a shower/t-storm risk late June 29 to early June 30 then breezy and cooler weather the remainder of July 30 followed by fair weather and slight warming trend July 1-2.

DAYS 11-15 (JULY 3-7)
Weather systems will be fairly weak with high pressure in control and only 1 or 2 passing disturbances with brief shower/t-storm threats. Mainly dry weather. Still lacking major heat but it should be seasonably warm overall.

9:05AM

DAYS 1-5 (JUNE 22-26)
A nice weekend in general, but today will feature a gusty breeze and we’ll also pop some clouds especially later in the day as what ground heating we do get interacts with cold air above and a weak trough moving north to south behind the recently-departing low pressure system. These clouds may lead to a few isolated showers and even a brief thunderstorm, but any that occur will be small and rather quick-moving. High pressure settles in for a very nice Sunday and hangs on for Monday as well, with a gradual warm-up, but still we lack any hot weather. Weak low pressure tracking eastward will pass north of southern New England and drag a quick warm front / cold front combo across our area Tuesday, with some unsettled weather, before weak high pressure returns with fair weather Wednesday.
Forecast details…
TODAY: Sunny start then a cloud/sun mix. A passing shower or thunderstorm possible mid afternoon to early evening. Any storms may contain heavy rain and small hail. Highs 72-79, coolest Cape Cod. Wind NW 10-20 MPH.
TONIGHT: Clearing. Lows 53-60. Wind NW 5-15 MPH early then diminishing.
SUNDAY: Mostly sunny. Highs 76-83, coolest coast. Wind light variable with sea breezes.
SUNDAY NIGHT: Mostly clear. Lows 54-61. Wind light variable.
MONDAY: Mostly sunny. Highs 78-85, cooler some coastal areas. Wind light W but with sea breezes possible.
MONDAY NIGHT: Partly cloudy. Lows 60-67. Wind light S.
TUESDAY: Mostly cloudy. Risk of a shower or thunderstorm. More humid. Highs 73-80. Wind S 5-15 MPH.
TUESDAY NIGHT: Clearing. Less humid. Lows 58-65. Wind W 5-15 mph.
WEDNESDAY: Partly cloudy. Highs 75-82. Wind W 5-15 MPH.

DAYS 6-10 (JUNE 27-JULY 1)
A weak disturbances bring shower chances early June 27 and early June 30 based on current timing, otherwise a mostly dry period of weather is expected with near to slightly below normal temperatures.

DAYS 11-15 (JULY 2-6)
Weather systems will be fairly weak with high pressure in control and only 1 or 2 passing disturbances with brief shower/t-storm threats. Mainly dry weather. Still lacking major heat but it should be seasonably warm overall.
