DAYS 1-5 (JUNE 30-JULY 4)
Not much new on this update, just a few tweaks. A disturbance passing through Maine should keep its showers and storms northeast of the WHW forecast area today and tonight but will watch it and alert in comments section later if something does end up a little closer than expected, and that would be southeastern NH or northeastern MA if it did happen, and sometime tonight. This disturbance, and the outflow from the storms associated with it, will push a boundary with a little more momentum into eastern areas during Sunday, sparing the coast the highest heat. This will penetrate inland some distance, but the impact is much less by the time we reach this time of year than it would have been earlier in the spring, and with the heat already in place, we’re starting at a much higher level before knocking things back. This air will hang around into Monday but the air mass will warm under the early July sunshine so don’t expect refreshing ocean wind everywhere, although the coast may still be quite comfy Monday, despite the air being rather humid. The hottest days of this period for the region overall should be Tuesday and Wednesday. There is only the slightest risk of an isolated thunderstorm Wednesday but the chance is so remote I hesitate to even mention it. I believe warm air aloft should keep it stable enough to overcome a little surface convergence and the heat/humidity at the ground. But where it is the holiday itself, the forecast is high stakes and will of course be closely monitored.
Forecast details…
TODAY: Mostly sunny. Highs 76-82 Cape Cod, 80-87 South Coast, 86-93 elsewhere. Wind W to SW up to 10 MPH.
TONIGHT: Mostly clear. Lows 66-75, warmest in urban areas. Wind light SW.
SUNDAY: Mostly sunny. Highs 78-85 shoreline and 86-95 elsewhere but falling back through the 70s immediate coast and through the 80s for up to 25 miles inland from east-facing shores during the late morning and afternoon. Wind SW up to 10 MPH shifting to E and NE.
MONDAY: Sunny. Lows from the upper 60s to upper 70s, warmest urban areas. Highs from the upper 70s to lower 80s immediate coast, ranging up from middle 80s to middle 90s further inland.
TUESDAY: Mostly sunny. Lows from the upper 60s to upper 70s, warmest urban areas. Highs from the upper 80s to middle 90s, coolest coastal areas.
WEDNESDAY – INDEPENDENCE DAY: Partly cloudy. Lows from the upper 60s to upper 70s. Highs from the upper 80s to middle 90s but cooler in some coastal areas.

DAYS 6-10 (JULY 5-9)
Currently expecting hot and humid weather but no storm threat July 5, and similar but with an isolated storm threat July 6 and 7. Better risk of showers/storms July 8 with a cold front and the hot weather pattern is broken, at least temporarily, by the end of the period.

DAYS 11-15 (JULY 10-14)
Less heat, back to more seasonable temperatures as the ridge backs up further west and a couple disturbances move through with shower and thunderstorm chances.

7:27AM

DAYS 1-5 (JUNE 29-JULY 3)
When Independence Day falls on a Wednesday, there is a perfect reason to have TWO “Fourth of July Weekends”, and they are both included in this outlook, the first one rapidly approaching, and it will be hot and increasingly humid as an upper level high pressure ridge takes over the weather. In fact, other than the remotest risk of a shower north and west of Boston this evening with a weak disturbance, I now do not see any possibility of rain for the remainder of this period, just plenty of heat, although there will be episodes of cooling sea breezes in some coastal areas, especially Sunday and Monday as it stands now. Forecast details…
TODAY: Sunshine, few clouds late. Highs 78-85 shorelines, 85-92 elsewhere. Wind NW up to 10 MPH with light coastal sea breezes.
TONIGHT: Partly cloudy evening with a slight risk of a brief shower west and north of Boston. Clearing overnight. Lows 62-69. Wind light variable.
SATURDAY: Mostly sunny. Highs 76-82 Cape Cod, 80-87 South Coast, 86-93 elsewhere. Wind W to SW up to 10 MPH.
SATURDAY NIGHT: Mostly clear. Lows 66-75, warmest in urban areas. Wind light SW.
SUNDAY: Mostly sunny. Highs 78-85 Cape Cod, 86-95 elsewhere. Wind SW up to 10 MPH but coastal sea breezes likely, especially east-facing shores which may drop to the 70s.
MONDAY: Sunny. Lows from the upper 60s to upper 70s, warmest urban areas. Highs from the upper 80s to middle 90s but cooling in some coastal areas.
TUESDAY: Mostly sunny. Lows from the upper 60s to upper 70s, warmest urban areas. Highs from the upper 80s to middle 90s, coolest coastal areas.

DAYS 6-10 (JULY 4-8)
More heat and humidity, but the thunderstorm chance may increase somewhat toward the end of the period as the ridge center shifts a little to the west and a disturbance or two get closer to the region.

DAYS 11-15 (JULY 9-13)
Less heat, back to more seasonable temperatures as the ridge backs up further west and a couple disturbances move through with shower and thunderstorm chances.

7:23AM

DAYS 1-5 (JUNE 28-JULY 2)
A warm front passes through this morning and a cold front approaches later today. Most of the support for widespread showers and embedded thunderstorms lies with the warm front and we’ll see this with another round of soaking showers crossing the region through midday. During the afternoon activity becomes scattered to isolated, but any storms that do form can be strong, so we need to watch for that. All quiets down this evening and then we shift focus to the incoming heat, initially with lower humidity Friday after today’s mugginess, and then building humidity returns thereafter. Forecast details…
TODAY: Mostly cloudy with showers likely and possibly a thunderstorm morning. Partly sunny with isolated showers and possible thunderstorms afternoon. Any thunderstorms can be briefly strong with downpours and gusty winds. Humid. Highs 75-82. Wind SW 10-20 MPH with higher gusts.
TONIGHT: Clearing. Patchy fog. Humid evening, less humid overnight. Lows 58-65. Wind W 5-15 MPH.
FRIDAY: Mostly sunny. Highs 78-85 South Coast, 85-92 inland. Wind W 5-15 MPH.
SATURDAY: Sunny. Lows in the 60s. Highs from near 80 South Coast to around 90 elsewhere.
SUNDAY: Sunny. Humid. Lows from the middle 60s to lower 70s. Highs from the lower to middle 80s South Coast, upper 80s to middle 90s elsewhere.
MONDAY: Sunny. Humid. Lows from the upper 60s to middle 70s. Highs from the middle 80s to middle 90s, coolest South Coast.

DAYS 6-10 (JULY 3-7)
An old frontal boundary may trigger a shower or thunderstorms July 3. Another front may approach later in the period with a shower and thunderstorm threat, but otherwise it’s fair and hot as high pressure ridging dominates. Sea breezes may cool coastal areas at times.

DAYS 11-15 (JULY 8-12)
As high pressure ridging slides back to the west the jet stream will be allowed to sink southward and provide a few more shower and thunderstorm threats with more variable temperatures during this period.

7:08AM

DAYS 1-5 (JUNE 27-JULY 1)
A warm front approaches today and passes tonight with more cloudiness (than previously forecast) but still not a bad day, and showers holding off until late evening and overnight, which will become more numerous through Thursday morning ahead of a cold front, which will pass through during the afternoon. But the air behind this front is not really much cooler than the air ahead of it. It’s more of a dew point boundary that will push out a wedge of high humidity that arrives overnight and early Thursday. So Friday will be less humid but will turn very warm as high pressure ridging builds over the eastern US. This sets up a hot weekend to end June and begin July. Forecast details…
TODAY: Limited sun through lots of high clouds. Highs 76-83. Wind S up to 10 MPH.
TONIGHT: Mostly cloudy. Showers arriving west to east late evening and overnight. Lows 60-67. Wind S 5-15 MPH.
THURSDAY: Mostly cloudy with showers likely and possibly a thunderstorm morning. Partly sunny with isolated showers and possible thunderstorms afternoon. Any thunderstorms can be briefly strong with downpours and gusty winds. Humid. Highs 75-82. Wind SW 10-20 MPH with higher gusts.
FRIDAY: Mostly sunny. Lows from the upper 50s to middle 60s. Highs from the middle 80s to lower 90s except cooler some coastal areas.
SATURDAY: Sunny. Lows in the 60s. Highs from near 80 South Coast to around 90 elsewhere.
SUNDAY: Sunny. Humid. Lows from the middle 60s to lower 70s. Highs from the lower to middle 80s South Coast, upper 80s to middle 90s elsewhere.

DAYS 6-10 (JULY 2-6)
A ridge of high pressure will dominate the weather and this is a hot pattern for this area with mainly dry weather. Exceptions are disturbances that travel over the ridge, which will be centered to the west of New England, sometimes can bring brief thunderstorm threats. A weakening front may make it into the vicinity around July 3 and trigger a few storms. Also some coastal areas can cool at times due to sea breezes.

DAYS 11-15 (JULY 7-11)
As high pressure ridging slides back to the west the jet stream will be allowed to sink southward and provide a few more shower and thunderstorm threats with more variable temperatures during this period.

7:38AM

DAYS 1-5 (JUNE 26-30)
No changes again. Two great days, then a front, favoring faster timing still, then heat knocks on the door at the end of the week.
Forecast details…
TODAY: Mostly sunny. Highs 76-83. Wind W 5-15 MPH.
TONIGHT: Clear. Patchy fog interior wetlands. Lows 48-53 interior valleys / wetlands, 53-58 elsewhere. Wind light variable.
WEDNESDAY: Partly cloudy. Highs 77-84. Wind S 5-15 MPH.
THURSDAY: Partly sunny. Chance of showers mainly morning to mid afternoon. Lows in the 60s. Highs from the middle 70s to lower 80s.
FRIDAY: Mostly sunny. Lows from the upper 50s to middle 60s. Highs from the middle 80s to lower 90s except cooler some coastal areas.
SATURDAY: Sunny. Lows in the 60s. Highs from near 80 South Coast to around 90 elsewhere.

DAYS 6-10 (JULY 1-5)
A ridge of high pressure will dominate the weather and this is a hot pattern for this area with mainly dry weather. Exceptions are disturbances that travel over the ridge, which will be centered to the west of New England, sometimes can bring brief thunderstorm threats. Also some coastal areas can cool at times due to sea breezes.

DAYS 11-15 (JULY 6-10)
Similar pattern continues with heat and limited thunderstorm chances at first, and then a couple stronger disturbances may bring better thunderstorm chances and cut into the heat thereafter.

7:07AM

DAYS 1-5 (JUNE 25-29)
As we start the week, there are no big changes to the outlook. A disturbance and boundary left behind last night’s low pressure passage will trigger a few showers in eastern areas today before it clears out tonight and high pressure brings fair weather Tuesday and Wednesday. A cold front will cross the region Thursday with showers and still leaning toward an earlier timing on this. We feel the first of rapidly building heat by Friday as high pressure expands into the eastern US and drives out what little cool air arrives behind Thursday’s front. Forecast details…
TODAY: Partly sunny. Isolated to scattered showers possible, favoring southeastern NH and eastern MA late morning through mid afternoon. Highs 70-77. Wind N 5-15 MPH.
TONIGHT: Partly cloudy. Lows 52-59. Wind light N.
TUESDAY: Mostly sunny. Highs 76-83. Wind W 5-15 MPH.
TUESDAY NIGHT: Clear. Patchy fog interior wetlands. Lows 48-53 interior valleys / wetlands, 53-58 elsewhere. Wind light variable.
WEDNESDAY: Partly cloudy. Highs 77-84. Wind S 5-15 MPH.
THURSDAY: Partly sunny. Chance of showers mainly morning to mid afternoon. Lows in the 60s. Highs from the middle 70s to lower 80s.
FRIDAY: Mostly sunny. Lows from the upper 50s to middle 60s. Highs from the middle 80s to lower 90s except cooler some coastal areas.

DAYS 6-10 (JUNE 30-JULY 4)
A ridge of high pressure will dominate the weather and this is a hot pattern for this area with mainly dry weather. Exceptions are disturbances that travel over the ridge, which will be centered to the west of New England, sometimes can bring brief thunderstorm threats. Also some coastal areas can cool at times due to sea breezes.

DAYS 11-15 (JULY 5-9)
Similar pattern continues with heat and limited thunderstorm chances at first, and then a couple stronger disturbances may bring better thunderstorm chances and cut into the heat somewhat later in the period.

8:32AM

DAYS 1-5 (JUNE 24-28)
In some places the warm front still has not passed as we don’t have a very strong push of warm air this time, so the cooler air at the surface has been tough do dislodge, much like what we often see in the winter and spring, but that warm/muggy air will finally get into all areas and then as a cold front approaches later we will see the risk of showers increase from later this afternoon into tonight, as indicated previously. After the front goes by we do see drier air tomorrow but cold air aloft and a boundary setting up near the eastern coastal areas will make development of showers probable during the afternoon and evening hours. Not expecting widespread rainfall but any of these showers may be briefly heavy. The next “interruption” comes in the form of a cold front sometime Thursday, and currently leading toward the first half of the day, but at day 5 there is not high confidence regarding the timing of a front. Forecast details…
TODAY: Mostly cloudy. Scattered showers to general showers favoring late afternoon and evening. Humid. Highs 73-80. Wind SW 10-20 MPH.
TONIGHT: Cloudy with showers likely evening. Partly cloudy overnight. Patchy fog. Humid evening, drier overnight. Lows 58-65. Wind W 5-15 MPH shifting to N.
MONDAY: Partly sunny. Isolated to scattered showers possible. Less humid. Highs 70-77. Wind N 5-15 MPH.
MONDAY NIGHT: Partly cloudy. Isolated showers early. Lows 52-59. Wind light N.
TUESDAY: Mostly sunny. Highs 76-83. Wind W 5-15 MPH.
WEDNESDAY: Partly cloudy. Lows from the middle 50s to lower 60s. Highs from the upper 70s to middle 80s.
THURSDAY: Partly sunny. Chance of showers mainly morning to early afternoon. Lows in the 60s. Highs from the middle 70s to lower 80s.

DAYS 6-10 (JUNE 29-JULY 3)
High pressure ridge takes over with building heat, mainly dry weather and only isolated thunderstorms possible.

DAYS 11-15 (JULY 4-8)
High pressure ridge dominating the weather should result in mainly dry weather and above to much above normal temperatures, but we’ll have the jet stream close enough to the north and the center of high pressure just far enough west to result in the possibility of disturbances and passing showers and storms at times, so will have to monitor for those, especially during the second half of the period.

9:03AM

DAYS 1-5 (JUNE 23-27)
No changes to the weekend forecast as an approaching warm front makes today a cloudy and cool day with a few areas of rain moving through, however this is not going to be a washed-out day and there will be rather long episodes of rain-free time for many locations. A cold front follows this by late Sunday, allowing the day to be warmer and humid ahead of it, but also bringing showers and possibly a thunderstorm, especially late-day and evening. As drier air moves in by Monday behind the cold front we still eye a disturbance that will likely set off scattered showers that day. High pressure brings fair weather Tuesday and Wednesday.
TODAY: Mostly cloudy. A few periods of rain possible, but much of time rain-free. Highs 62-67 coast, 67-72 interior. Wind E 5-10 MPH.
TONIGHT: Mostly cloudy. A few episodes of showers. Increasingly humid. Lows 60-65. Wind light SE shifting to SW.
SUNDAY: Mostly cloudy. Scattered showers to general showers favoring afternoon and evening. Humid. Highs 73-80. Wind SW 10-20 MPH.
SUNDAY NIGHT: Cloudy with showers likely evening. Partly cloudy overnight. Patchy fog. Humid evening, drier overnight. Lows 58-65. Wind W 5-15 MPH shifting to N.
MONDAY: Partly sunny. Isolated to scattered showers possible. Less humid. Highs 70-77. Wind N 5-15 MPH.
TUESDAY: Mostly sunny. Lows in the 50s. Highs from the middle 70s to lower 80s.
WEDNESDAY: Partly cloudy. Lows from the middle 50s to lower 60s. Highs from the upper 70s to middle 80s.

DAYS 6-10 (JUNE 28-JULY 2)
A front passes by early June 28 with a shower risk, then the pattern brings building heat and mainly dry weather with just a risk of isolated showers or thunderstorms at times as June ends and July arrives.

DAYS 11-15 (JULY 3-7)
High pressure ridge dominating the weather should result in mainly dry weather and above to much above normal temperatures, but we’ll have the jet stream close enough to the north and the center of high pressure just far enough west to result in the possibility of disturbances and passing showers and storms at times, so will have to monitor for those.

7:11AM

DAYS 1-5 (JUNE 22-26)
This post does not carry much change from what was posted at this time yesterday. Still looking at a warm front (Saturday) / cold front (Sunday) weekend, unsettled but not washed out. Still keeping the shower threat in the Monday forecast for one additional disturbance. Expecting fair weather beyond that into midweek as high pressure arrives. Forecast details…
TODAY: Mostly sunny. Highs 68-75 coast, 75-82 inland. Wind light variable with sea breezes.
TONIGHT: Increasing clouds. Lows 55-62. Wind light SE.
SATURDAY: Mostly cloudy. A few periods of rain possible, favoring mid morning through early afternoon. Highs 65-70 coast, 70-75 interior. Wind SE 5-15 MPH.
SATURDAY NIGHT: Mostly cloudy. A few episodes of showers. Increasingly humid. Lows 60-65. Wind light SE shifting to SW.
SUNDAY: Mostly cloudy. Scattered showers to general showers favoring afternoon and evening. Humid. Highs 73-80. Wind SW 10-20 MPH.
MONDAY: Partly sunny. Isolated to scattered showers possible. Less humid. Lows in the 60s. Highs in the 70s.
TUESDAY: Mostly sunny. Lows in the 50s. Highs from the middle 70s to lower 80s.

DAYS 6-10 (JUNE 27-JULY 1)
Expecting mainly dry weather for this period but will watch for small disturbances coming along a weaker jet stream in a general west to east flow. Temperatures near to above normal.

DAYS 11-15 (JULY 2-6)
Much of this period looks dry with minimal shower and thunderstorm threat but always need to watch for disturbances with the jet stream not too far to the north. Temperatures generally above normal with a high pressure ridge in the eastern US.

7:14AM

COMMENTARY
The Summer Solstice occurred at 6:07AM EDT so it’s now officially summer by astronomical standards, lagging behind almost everyone else’s definition of the start of summer, and proving, though probably to no real benefit, once again why it doesn’t do us good to rush the seasons. Interesting how we’ve decided to ignore the real in favor of the made-up, but that’s how we do it in society I suppose.

DAYS 1-5 (JUNE 21-25)
A disturbance that passed south of the region overnight exits early today with no more than few rain drops around Nantucket, but a frontal boundary coming down from the north along with a developing sea breeze will set up a wind convergence area and may trigger a few showers and maybe even a thunderstorm this afternoon and very early evening anywhere from the Boston and Worcester metro areas southward. High pressure will control the weather Friday but a light onshore flow will keep it on the cooler side of average. The weekend will be somewhat unsettled but not a washout. I would not cancel any plans at this point. We’ll see a warm front pass through the region by Saturday night, and ahead of it we’ll see abundant cloudiness and patchy rain, but a good amount of this rain may peel off to the east and push through southeastern areas from Saturday morning to early afternoon, leaving much of the region rain-free. Humidity spikes by early Sunday and by later Sunday a cold front will be moving through the region bringing a fairly widespread shower risk. Drier air arrives Monday but one additional disturbance passing through may still trigger a few showers, but that being 5 days away is far from a certainty. Forecast details…
TODAY: Variably cloudy morning with brief rain Nantucket. Partly sunny afternoon with isolated to scattered showers and possibly a thunderstorm in MA/RT/eastern CT. Highs 73-81, coolest coast. Wind light variable early then E 5-15 MPH except N 5-15 MPH over central MA to eastern CT.
TONIGHT: Clearing. Patchy fog interior wetlands. Lows 50-55 interior valleys, 55-60 elsewhere. Wind light variable.
FRIDAY: Mostly sunny. Highs 68-75 coast, 75-82 inland. Wind light variable with sea breezes.
FRIDAY NIGHT: Increasing clouds. Lows 55-62. Wind light SE.
SATURDAY: Mostly cloudy. A few periods of rain possible, favoring southeastern areas from mid morning through early afternoon. Highs 65-70 coast, 70-75 interior. Wind SE 5-15 MPH.
SUNDAY: Mostly cloudy. Scattered showers to general showers favoring afternoon and evening. Humid. Lows in the 60s. Highs from the middle 70s to lower 80s.
MONDAY: Partly sunny. Isolated to scattered showers possible. Less humid. Lows in the 60s. Highs in the 70s.

DAYS 6-10 (JUNE 26-30)
Expecting mainly dry weather for this period but will watch for small disturbances coming along a weaker jet stream in a general west to east flow. Temperatures near to above normal.

DAYS 11-15 (JULY 1-5)
Much of this period looks dry with minimal shower and thunderstorm threat but always need to watch for disturbances with the jet stream not too far to the north. Temperatures generally above normal with a high pressure ridge in the eastern US.

7:22AM

DAYS 1-5 (JUNE 20-24)
A disturbance will pass south of the region tonight and early Thursday, bringing some cloudiness but it is still looking to me like the rain at worst skirts the South Coast but otherwise stays south of the region. Cannot rule out a pop up shower Thursday afternoon interior MA to RI and eastern CT as there will be a little air convergence there. By Saturday, a warm front moving through the region may bring a few patches of insignificant light rain to the region. Don’t cancel any plans. This will be followed by a cold front crossing the region later Sunday, which may end up as a cloudier but muggy day overall with a threat of showers and possible thunderstorms. Forecast details…
TODAY: Mostly sunny morning. Partly sunny afternoon. Highs 76-84, coolest coast. Wind light variable to SW but local coastal sea breezes.
TONIGHT: Mostly cloudy. Brief rain possible South Coast. Lows 52-60. Wind light variable.
THURSDAY: Clouds most dominant southern areas early otherwise partly to mostly sunny. A pop up shower possible mainly mid to late afternoon central MA, RI, and eastern CT. Highs 75-83, coolest coast. Wind light E to SE except NE to N over central MA to eastern CT.
THURSDAY NIGHT: Clearing. Lows 50-55 interior valleys, 55-60 elsewhere. Wind light variable.
FRIDAY: Mostly sunny. Highs 75-80 coast, 80-85 inland. Wind light variable with sea breezes.
SATURDAY: Variably cloudy. Slight chance of brief light rain. More humid at night. Lows from the upper 50s to lower 60s. Highs from the middle 70s to lower 80s, coolest coastal areas.
SUNDAY: Mostly cloudy. Scattered showers. Chance of thunderstorms. Humid. Lows in the 60s. Highs from the middle 70s to lower 80s.

DAYS 6-10 (JUNE 25-29)
Expecting mainly dry weather for this period but will watch for small disturbances coming along a weaker jet stream in a general west to east flow. A trough nearby early in the period means temperatures will start out slightly below normal and a ridge to the west later in the period translates into warmer weather arriving.

DAYS 11-15 (JUNE 30-JULY 4)
Much of this period looks dry with minimal shower and thunderstorm threat. Temperatures trending above normal.

7:25AM

DAYS 1-5 (JUNE 19-23)
In comes the dry air today and this leads to a period of more seasonable weather over the next several days with temperature in each location dependent on wind direction and/or speed. For example, tonight will be a cool night over interior valleys as dry air is in place and wind drops to calm. Coastal areas will often be cooler during the second half of the week as the air flow will come the cooler ocean water. But other than a shower to start the day around Cape Cod and the Islands today, expect generally 5 days of dry weather ahead. Disturbance that threatened to bring light rain to the South Coast late Wednesday appears that it will stay too far south to do so. Summer arrives with the solstice at 6:07AM Thursday June 21. Forecast details…
TODAY: Partly cloudy morning including an early shower around Cape Cod, then sunnier afternoon. Highs 75-83. Wind NW 5-15 MPH gusting 20 MPH or greater at times.
TONIGHT: Mostly clear. Lows 50-55 interior, 55-60 coastal areas and urban centers. Wind diminishing to calm.
WEDNESDAY: Mostly sunny. Highs 76-84, coolest coast. Wind light variable to SW but local coastal sea breezes.
WEDNESDAY NIGHT: Partly cloudy. Lows 52-60. Wind light variable.
THURSDAY: Mostly sunny. Highs 75-83, coolest coast. Wind light E to SE.
FRIDAY: Mostly sunny. Lows from the middle 50s to lower 60s. Highs from the middle 70s to middle 80s, coolest coastal areas.
SATURDAY: Partly sunny. Lows from the upper 50s to lower 60s. Highs from the middle 70s to lower 80s, coolest coastal areas.

DAYS 6-10 (JUNE 24-28)
A disturbance comes through the region and brings the threat of showers June 24 followed by another threat of showers around June 27. Temperatures start the period near to even slightly below normal but end it near to above normal.

DAYS 11-15 (JUNE 29-JULY 3)
Much of this period looks dry with minimal shower and thunderstorm threat. Temperatures trending above normal.

6:41AM

DAYS 1-5 (JUNE 18-22)
A one-day stand for heat/humidity and a chance of thunderstorms today as a shot of summer comes in just ahead of a cold front that will then sink southward across southern New England tonight. As for timing of storms, any time after 2PM from north to south, but they may come in several waves into the nighttime hours. Don’t look for widespread severe weather. Despite the heat and humidity, some parameters are poor to marginal for severe weather so though storms in some areas may be strong to locally severe, this should be isolated and short-lived. Once this all pushes out of the region early Tuesday, a drying trend takes over. But the front will never get that far south of the region and a disturbance riding along it, though currently expected to stay far enough south to keep most of its rain out of the region, will likely spread cloudiness back into the area Wednesday, and brief rain may reach the South Coast area, before it clears out Thursday and the end of the week sees fair and warm weather. Forecast details…
TODAY: Partly cloudy. Isolated to scattered showers and thunderstorms mid afternoon on. Humid. Highs 70-77 Cape Cod, 78-87 remainder of South Coast, 88-96 elsewhere. Wind W 10-20 MPH. Winds can be variable, strong, and gusty near any storms.
TONIGHT: Variably cloudy. Scattered showers/thunderstorms. Patchy fog. Humid. Lows 66-74. Wind variable 5-15 MPH. Wind can be strong and gusty near any storms.
TUESDAY: Clearing. Lowering humidity. Highs 78-85. Wind NW to N 5-15 MPH.
TUESDAY NIGHT: Clear. Lows 56-63. Wind light N.
WEDNESDAY: Increasing clouds. Risk of light rain South Coast at night. Highs 75-83. Wind light variable.
THURSDAY: Clearing. Lows from the upper 50s to lower 60s. Highs from the middle 70s to lower 80s.
FRIDAY: Partly cloudy. Lows from the upper 50s to lower 60s. Highs from the upper 70s to middle 80s.

DAYS 6-10 (JUNE 23-27)
High pressure brings fair weather June 23. Trough from the west brings a chance of wet weather June 24. Fair weather returns June 25-26 before the next risk of showers around June 27. Temperatures somewhat variable but averaging near normal overall.

DAYS 11-15 (JUNE 28-JULY 2)
Much of this period is expected to see dry weather with temperatures near to above normal.

7:29AM

DAYS 1-5 (JUNE 17-21)
This Father’s Day morning I’m coming as close as I ever will to taking a day off and basically using yesterday’s blog as a copy/paste/edit because there really are no changes to the forecast anyway. Good timing. Beautiful day today, heat and humidity blast Monday, thunderstorm threat later Monday and Monday night (still have to work out the timing and more specific threats), heat departs and humidity drops off Tuesday, and more great weather middle of next week. Forecast details…
TODAY: Sunshine with a few high clouds at times. Highs 72-78 all coastal areas, 78-85 interior except 85-90 interior valleys. Wind light variable with sea breezes.
TONIGHT: Partly cloudy. Increasingly humid. Lows 58-67. Wind W up to 10 MPH.
MONDAY: Partly cloudy. Late-day or evening thunderstorms possible especially southern NH and northern MA. Humid. Highs 82-90 South Coast, 90-97 elsewhere. Wind W 10-20 MPH. Winds near any storms may be variable, strong, and gusty.
MONDAY NIGHT: Variably cloudy. Scattered showers/thunderstorms. Any storms may be strong. Humid. Lows 65-72. Wind W 5-15 MPH but can be variable, strong, and gusty near any storms.
TUESDAY: Variably cloudy with possible showers morning. Clearing afternoon. Humid early, then drying. Highs 77-84. Wind NW to N 5-15 MPH.
WEDNESDAY: Mostly sunny. Lows from the middle 50s to lower 60s. Highs from the upper 70s to middle 80s.
THURSDAY: Mostly sunny. Lows from the upper 50s to lower 60s. Highs from the upper 70s to middle 80s.

DAYS 6-10 (JUNE 22-26)
This looks like a mainly dry period with one interruption possible around June 24 with the potential for some wet weather. Temperatures near to above normal.

DAYS 11-15 (JUNE 27-JULY 1)
A brief shower threat around June 27 otherwise more of the same with mainly dry weather and temperatures near to above normal.

10:14AM

DAYS 1-5 (JUNE 16-20)
Trying to fine-tune things regarding the heat and any thunderstorm chance timing for Monday and will continue to work on that. Latest thoughts on that are the MCS threat stays mainly in Maine early Monday but that may set up a boundary or pre-frontal trough that could kick of a line of storms pushing from north northwest to south southeast late Monday afternoon to Monday evening. High heat is a certainty, along with humidity, for Monday itself, but still the temperature details will again come down to the amount of cloudiness in the sky during the hours of maximum heating. Before all of this, we have a great weekend, though don’t expect 100% clear sky the entire time. We will see episodic high level cloudiness, the remains of thunderstorms way upstream in southern Canada and the upper Plains and Midwest. Again, as stated before, this is a typical pattern for this time of year. Still thinking that a little humidity and a shower risk hangs on at least part of Tuesday before dry air returns into midweek. Forecast details…
