Sunday Forecast

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!

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.

Saturday Forecast

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.

Friday Forecast

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.

Thursday Forecast

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.
THURSDAY NIGHT: Partly cloudy. Areas of coastal fog early. Lows 62-69. Wind variable then NW up to 10 MPH.
FRIDAY: Partly cloudy. Highs 83-90. Wind W up to 10 MPH.
FRIDAY NIGHT: Clouding over. Rain or showers overnight. More humid. Lows 60-67. Wind light variable.
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.

Wednesday Forecast

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.
TONIGHT: Partly cloudy evening. Mostly cloudy with patchy fog overnight. Humid. Lows 60-67. Wind light S.
THURSDAY: Mostly cloudy early, then partly sunny. Slight risk of an isolated shower interior southern NH and MA. Slightly less humid. Highs 79-86. Wind light W.
THURSDAY NIGHT: Partly cloudy. Lows 62-69. Wind light W.
FRIDAY: Partly cloudy. Highs 83-90. Wind W up to 10 MPH.
FRIDAY NIGHT: Clouding over. Rain or showers overnight. More humid. Lows 60-67. Wind light variable.
SATURDAY: Cloudy with areas of fog and a chance of rain early, then partly sunny with scattered showers and thunderstorms. Humid. Highs 79-86. Wind variable 5-15 MPH.
SATURDAY NIGHT: Partly cloudy. Patchy fog. Humid. Lows 60-67. Wind W 5-15 MPH.
SUNDAY: Variably cloudy. Chance of showers/thunderstorms, favoring morning-midday. Humid, but drying late. Highs 76-83. Wind W 10-20 MPH shifting to N.

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.

Tuesday Forecast

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.
WEDNESDAY: Partly sunny. Slight risk of a shower or thunderstorm in the afternoon. Humid. Highs 77-84. Wind light variable, coastal sea breezes.
WEDNESDAY NIGHT: Partly cloudy. Slight risk of a shower or thunderstorm. Humid. Lows 60-67. Wind light S.
THURSDAY: Partly sunny. Less humid. Highs 79-86. Wind light W.
THURSDAY NIGHT: Partly cloudy. Lows 62-69. Wind light W.
FRIDAY: Partly cloudy. Highs 83-90. Wind W up to 10 MPH.
FRIDAY NIGHT: Partly cloudy. Lows 60-67. Wind W 5-15 MPH.
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.

Monday Forecast

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.
TONIGHT: Increasing clouds. Lows 55-62. Wind light variable.
TUESDAY: Mostly cloudy. Episodes of showers. Slight chance of a thunderstorm. Highs 68-75. Wind SE 5-15 MPH shifting to S.
TUESDAY NIGHT: Mostly to partly cloudy. Patchy fog. Chance of a shower. More humid. Lows 57-64. Wind light SW shifting to W.
WEDNESDAY: Partly sunny. Risk of a shower or thunderstorm in the afternoon. Humid. Highs 77-84. Wind light variable, coastal sea breezes.
WEDNESDAY NIGHT: Partly cloudy. Risk of a shower or thunderstorm. Humid. Lows 60-67. Wind light S.
THURSDAY: Partly sunny. Risk of a shower or thunderstorm early and again late. Humid. Highs 79-86. Wind light W.
THURSDAY NIGHT: Partly cloudy. Humid. Lows 62-69. Wind light W.
FRIDAY: Partly cloudy. Slight risk of a shower or thunderstorm. Humid. Highs 80-87. Wind W up to 10 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.

Sunday Forecast

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.

Saturday Forecast

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.

Friday Forecast

7:07AM

DAYS 1-5 (JUNE 21-25)
Transition day today. We transition out of this latest unsettled stretch gradually. We also transition from spring to summer rather suddenly as the solstice occurs at 11:54AM EDT. No that doesn’t mean it suddenly turns hot and sunny and stays that way. This is weather. We will, however, be heading for a very nice weekend, but first we have to go through the process of elongated low pressure coming across the region this morning with a cloudy sky and areas of showers, and leftover cold air above us this afternoon holding some cloudiness in place with the risk of an additional shower. By tonight, the dry air takes over and lasts through the weekend, with one possible exception, and that is there will be one more disturbance passing by with still some chilly air above on Saturday, and a shower or thunderstorm cannot be ruled out in the afternoon, favoring eastern areas. That chance is quite low, however, so don’t cancel plans. Just keep an eye out. Also, a gusty breeze will develop later today and continue into Saturday in response to low pressure departing to the east while high pressure approaches from the west. High pressure will bring the best weather of this 5 day period Sunday and Monday. By Tuesday, we’ll be feeling an increase in humidity and a disturbance moving in from the west will bring the risk of showers and thunderstorms once again.
Forecast details…
TODAY: Cloudy with lingering showers/drizzle/fog morning, then becoming partly sunny but with a risk of a passing shower this afternoon. Highs 71-78. Wind variable to NW increasing to 10-20 MPH with higher gusts by late-day.
TONIGHT: Clearing. Lows 52-59. Wind NW 10-20 MPH with higher gusts.
SATURDAY: Partly cloudy. Slight risk of a passing afternoon shower or thunderstorm favoring southeastern NH and eastern MA. Highs 72-79. Wind NW 10-20 MPH, diminishing late.
SATURDAY NIGHT: Mostly clear. Lows 53-60. Wind light variable.
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.

DAYS 6-10 (JUNE 26-30)
A somewhat more typical early summertime pattern, weaker jet stream but still west to east flow, on the warmer side of normal overall, with disturbances passing by about early June 27 and early June 30, both bringing the risk of a shower or thunderstorm in the late June 26 to early June 27 period and again late June 29 to early June 30. Much of this period will be rain-free.

DAYS 11-15 (JULY 1-5)
Trends are for previously-mentioned ridging to be a little further west and south leaving this area in a weak mean trough position with near normal temperatures and a couple opportunities for passing showers/storms, but not a bad pattern overall, just lacking a lot of heat and humidity.

Thursday Forecast

6:59AM

DAYS 1-5 (JUNE 20-24)
The final in a series of low pressure areas moving along a frontal boundary will cut across New England today through early Friday, bringing widespread shower activity, some of which will produce heavy rainfall and possible thunder. While there will not be any severe storms, we can expect to see some temporary road flooding where heaviest rain occurs, so use caution when traveling. Dry air arrives later Friday, clearing the region out and setting up a nice weekend, albeit breezy Saturday between our departed low pressure area and an approaching high pressure area. Sunday will be more tranquil as the high settles over the region. Contrary to my unsettled outlook for next Monday, it now appears that high pressure will hang on with more fair weather.
Forecast details…
TODAY: Cloudy. Showers likely, some possibly heavy. Humid. Highs 70-77. Wind SE 5-15 MPH.
TONIGHT: Cloudy. Showers likely, some possibly heavy. Risk of thunderstorms. Humid. Lows 60-67. Wind variable 5-15 MPH.
FRIDAY: Cloudy with lingering showers/drizzle/fog early, then becoming partly sunny but with a risk of a passing shower. Highs 71-78. Wind variable to NW increasing to 10-20 MPH with higher gusts by late-day.
FRIDAY NIGHT: Clearing. Lows 52-59. Wind NW 10-20 MPH with higher gusts.
SATURDAY: Partly cloudy. Highs 72-79. Wind NW 10-20 MPH, diminishing late.
SATURDAY NIGHT: Mostly clear. Lows 53-60. Wind light variable.
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.

DAYS 6-10 (JUNE 25-29)
A more typical summertime pattern settles in the early days of summer with higher humidity, fairly warm air, and a risk of showers and thunderstorms mainly with an approaching disturbance later June 25, a shower or storm possible with a passing disturbance sometime between late June 26 and early June 27, and maybe a few isolated showers/storms around later in the period, though no widespread rainfall would be likely with this set-up.

DAYS 11-15 (JUNE 30-JULY 4)
West to east flow over a high pressure ridge to the south and west of New England is a pattern that brings seasonable to warm weather, is rain-free most of the time, but also provides a few opportunities moving along the jet stream to bring a shower/t-storm threat. This is the pattern currently expected for this period.

Wednesday Forecast

7:25AM

DAYS 1-5 (JUNE 19-23)
A disturbance, the second in a series of 3, will pass south of the region today and may bring some showers to the South Coast. The rest of the region will escape those showers, although a diurnally-driven pop-up shower may still occur in central MA and southern NH this afternoon. The marine layer has resulted in a lot of low cloudiness which will eventually burn off in some areas but may have difficulty as the sun is compromised and much weaker due to higher cloudiness above. The third and final wave of low pressure in the series will be the strongest and also cut a pathway further north, bringing the boundary it’s riding along right into southern New England late Thursday and Thursday night. This will result in more widespread rainfall which also includes the risk of thunderstorms, though no severe weather will occur. We will have to watch for the possibility of road flooding due to some heavier rainfall in some locations. But this wave will be moving right along and drier air will begin to move in after a damp start to Friday, leaving the end of that day much different than it started, the contrast going from rather tranquil but overcast, damp, and rain or drizzle lingering as the day dawns, to a gusty wind, sunshine, and dry air as the day ends. What about the weekend? Looking great! Still may hold onto a gusty breeze Saturday as we will still be between high pressure approaching from the west and low pressure to the northeast of the region, and that will keep the air dry and the air temperature below 80. By Sunday, high pressure is right on us, and 80+ may occur away from where coastal sea breezes develops.

DAYS 6-10 (JUNE 24-28)
Warmer and more humid June 24-25 with a shower or thunderstorm threat both days. Less humid thereafter with a brief shower threat later June 26 or early June 27. Most of this 5-day period will be rain-free.

DAYS 11-15 (JUNE 29-JULY 3)
West to east flow over a high pressure ridge to the south and west of New England is a pattern that brings seasonable to warm weather, is rain-free most of the time, but also provides a few opportunities moving along the jet stream to bring a shower/t-storm threat. This is the pattern currently expected for this period.

Tuesday Forecast

7:18AM

DAYS 1-5 (JUNE 18-22)
A 4-day stretch of unsettled weather with waves of low pressure passing along a frontal boundary to the south of New England today and again Wednesday, the first bringing a shot of wet weather to the region later this morning into this afternoon, lingering longest to the south, the second confining itself mostly to the South Coast Wednesday while both late today and late Tuesday some showers may pop up along a convergence zone between ocean air and non-ocean air somewhere north and west of Boston. The third in the series of low pressure areas will not only be the strongest but also take a track just north of southern New England, bringing the most moisture, the heaviest rainfall threat, and a chance of thunderstorms, most of it occurring Thursday night, with wet weather lingering into Friday as the low pulls away. Drier air will be returning by later Friday and will set the region up for a nice start to the upcoming weekend as high pressure approaches, but a gusty breeze that develops during Friday between the departing low and approaching high may continue into Saturday.
Forecast details…
TODAY: Cloudy. Showers likely mainly late morning through early afternoon, most numerous southern MA, CT, RI, and may linger there longer. Pop-up showers possible southern NH and central MA mid to late afternoon. Highs 68-75. Wind light variable to SE.

WEDNESDAY NIGHT: Partly cloudy. Lows 57-64. Wind light variable.
THURSDAY: Becoming cloudy. Showers likely by late-day. Highs 70-77. Wind SE 5-15 MPH.
THURSDAY NIGHT: Cloudy. Showers likely. Risk of thunderstorms. Lows 60-67. Wind variable 5-15 MPH.
FRIDAY: Cloudy with lingering showers/drizzle/fog early, then clearing. Highs 71-78. Wind variable to NW increasing to 10-20 MPH with higher gusts by late-day.
FRIDAY NIGHT: Clear. Lows 54-61. Wind NW 10-20 MPH with higher gusts.
SATURDAY: Mostly sunny. Highs 73-80. Wind NW 10-20 MPH, diminishing late.

DAYS 6-10 (JUNE 23-27)
Great weather hangs on to finish off the weekend on June 23. A low pressure wave brings a threat of wet weather June 24. The June 25-27 period should be mostly fair, but not without a shower or thunderstorm threat a couple times, and overall warmer.

DAYS 11-15 (JUNE 28-JULY 2)
West to east flow over a high pressure ridge to the south and west of New England is a pattern that brings warm to occasional hot weather in, is rain-free most of the time, but also provides a few opportunities moving along the jet stream to bring a shower/t-storm threat. This is the pattern currently expected for this period.

Monday Forecast

7:19AM

DAYS 1-5 (JUNE 17-21)
This 5-day forecast brings us to the summer solstice which occurs at 11:54AM EDT on Friday June 21. There may be a little irony there because after a decent day today, the weather pattern this week may not have you thinking of summer that much until just about the moment it begins, if timing is just right. After high pressure gives us nice weather today, a frontal boundary sitting just south of or over southern New England will be the focus for disturbances and episodic showers Tuesday into early Friday, focused on daytime Tuesday and late Thursday to very early Friday, which may get out of here just in time for the official start of summer, allowing Friday to end nice…

TODAY: Sun and passing clouds. Highs 75-82. Wind N up to 10 MPH.

FRIDAY: Cloudy with lingering showers/drizzle/fog early, then clearing. Highs 71-78. Wind variable to NW 5-15 MPH.

DAYS 6-10 (JUNE 22-26)
High pressure should provide nice weather for the June 22-23 weekend before a low pressure wave brings wet weather June 24, followed by a return to fair weather and a more summer feel later in the period.

DAYS 11-15 (JUNE 27-JULY 1)
West to east flow over a high pressure ridge to the south and west of New England is a pattern that brings warm to occasional hot weather in, is rain-free most of the time, but also provides a few opportunities moving along the jet stream to bring a shower/t-storm threat. This is the pattern currently expected for this period.

Sunday Forecast

7:31AM

DAYS 1-5 (JUNE 16-20)
First off, if you are a father, then I wish you a Happy Father’s Day! For you and all the others it may be easy to look at your weather app forecast today and think we have a week of rain upcoming, and while we will be in an unsettled pattern during this 5-day period, we will not be getting “5 days of rain” either. A front that settles into the region today will waver around for the next several days, being a helper for showers to form and other areas of wet weather to move across from west to east, as disturbances pass by. We already have the majority of the shower activity to the south as I write this, and while some areas are wet many are dry. This will continue to be the case, and at times the shower threat will expand, while other times it drops off. Most of Monday now looks dry and may even feature more sunshine than I previously expected. It is difficult to time the wet weather episodes as we go through the next several days, so just be ready for it. Right now best guesses place better chances for most widespread shower activity early Tuesday, early Wednesday, and later Thursday.
Forecast details…
TODAY: Mostly cloudy. Scattered showers. More humid. Highs 70-77, cooler coastal areas. Wind SW 5-15 MPH.
TONIGHT: Mostly cloudy. Scattered showers. Patchy fog. Humid. Lows 60-67. Wind light variable.
MONDAY: Partly sunny. Highs 73-80. Wind light variable.
MONDAY NIGHT: Mostly cloudy. Numerous showers and a slight risk of thunderstorms, mainly late. Humid. Lows 60-67. Wind light variable.
TUESDAY: Mostly cloudy. Scattered showers/thunderstorms, favoring morning hours. Humid. Highs 73-80. Wind light variable.
TUESDAY NIGHT: Variably cloudy. Slight risk of showers. Humid. Lows 60-67. Wind light variable.
WEDNESDAY: Variably cloudy. Showers likely in the morning. Slight chance of showers thereafter. Highs 73-80. Wind light variable.
WEDNESDAY NIGHT: Partly cloudy. Lows 56-63. Wind light variable.
THURSDAY: Mostly cloudy. Showers likely especially late day or nighttime. Highs 70-77. Wind light variable.

DAYS 6-10 (JUNE 21-25)
Wet start, dry finish June 21 as summer officially arrives to below normal temperatures. A seasonably warm and dry weekend follows June 22-23 as high pressure looks like it will be timed just right. Wet weather threat returns June 24 but departs the next day, based on rough timing of systems this far in advance.

DAYS 11-15 (JUNE 26-30)
The trend for late June is west to east flow but more high pressure ridging to the south of New England. This pattern is warm, rain-free most of the time but still carries risk of passing shower/storms at times from jet stream disturbances.
