DAYS 1-5 (JUNE 26-30)

This five-day forecast period covers the home stretch of June. It starts today with a humid day. A warm front crossing the region this morning brings a band of widespread showers. A rumble of thunder can’t be rule out through mid morning from the South Coast to South Shore of MA before the rain exits. During the hours from mid to late morning until late in the day we see warmth and humidity with a sun / cloud mix. The amount of sun overall will determine how much we can destabilize the atmosphere to aid in the development and sustaining of showers and thunderstorms that will be triggered by an approaching cold front as low pressure moves across southeastern Canada. The greatest potential for strong to locally severe storms will be north of I-90 between 4 p.m. and 8 p.m., and this afternoon it becomes a “now-casting” situation to monitor what goes on. This activity will fade as it tracks to the south and east and loses support. If any storms do become severe, wind damage is the primary threat, but an instance of hail 1 inch or greater in diameter is not impossible. The cold front goes through tonight but temporarily slows near the South Coast as a weak wave of low pressure moves west to east along it. This can hold the shower chance near the South Coast into Saturday morning with some cloudiness but rain-free weather elsewhere. These clouds then move out but as they depart, we’ll see diurnal cloud development and a couple of these could grow enough to produce a spot shower or thunderstorm Saturday afternoon. These would be isolated with most locations missing out. Areas that did see them would only be wet for a brief time, but could experience a downpour. So do keep an eye out if you have outdoor plans. We repeat this chance on Sunday, but to a slightly lesser degree with again most of the region just seeing fair weather. Temperatures this weekend will be seasonable with humidity at comfortable levels. Coastal areas will be a bit cooler each day with a tendency for onshore winds. High pressure provides generally fair and warm weather Monday and Tuesday, however during Tuesday we will have to keep an eye out for a disturbance in a northwesterly air flow aloft that could bring a passing shower or t-storm to some locations. At day 5 the confidence on this detail is low.

TODAY: Cloudy through mid morning with showers and the slight chance of a thunderstorm west to east. Partly sunny late morning through mid afternoon. Mostly cloudy late-day with showers and thunderstorms likely, particularly north of I-90 including the potential for a strong to severe storm. Highs 78-85. Dew point peaking in upper 60s. Wind S to SW 10-20 MPH, higher gusts possible.

TONIGHT: Partly to mostly cloudy. Any early showers / thunderstorms southeastern areas will move out. Patchy fog. Lows 60-67. Dew point near 60. Wind W up to 10 MPH.

SATURDAY: Lots of clouds morning to midday including the chance of light rain near the South Coast, then a sun / cloud mix including the slight chance of a pop-up afternoon shower over inland locations. Highs 75-82. Dew point falls below 60. Wind variable to E up to 10 MPH.

SATURDAY NIGHT: Mostly clear. Fog patches lower elevations. Lows 55-62. Dew point lower to middle 50s. Wind calm.

SUNDAY: Sunny start, then a sun / cloud mix. Slight chance of a pop-up shower or thunderstorm during the afternoon. Highs 77-84, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.

SUNDAY NIGHT: Clearing. Lows 58-65. Wind variable up to 10 MPH.

MONDAY: Sunny to partly cloudy. Highs 78-85, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.

MONDAY NIGHT: Mostly clear. Lows 60-67. Wind variable to W up to 10 MPH.

TUESDAY: Sunny to partly cloudy. Remote chance of an isolated shower or thunderstorm. Highs 80-87. Wind W 5-15 MPH.

DAYS 6-10 (JULY 1-5)

General pattern features a northwesterly flow aloft, which is a seasonably warm pattern here with higher heat held off to our west. This pattern is mostly dry, but also features the chance for a few showers and thunderstorms to ride over the top of the ridge to our west and southeastward across New England. Sometimes these can be remnants, other times stronger and more organized. With this period of time leading up to and including the holiday weekend, there are many outdoor plans so it will be important to pay close attention to the weather each day regarding plans and travel to and from events.

DAYS 11-15 (JULY 6-10)

Some general pattern configuration expected – northwesterly flow. Some temperature variability including the chance for a hotter day or two, but also the chance for a few passing showers and thunderstorms. Dry weather the majority of the time.

DAYS 1-5 (JUNE 25-29)

High pressure hangs on with dry weather during the day today but clouds will tend to increase ahead of a warm front extending from low pressure moving northeastward into the Great Lakes. As this low continues its journey into and across southeastern Canada tonight through Friday, its warm front will traverse the region with a band of showers and possibly some embedded thunder in the late night hours tonight to early morning hours Friday, exiting eastern areas around or shortly after the break of day. During the day Friday, we’ll spend many hours in the warm sector of the low with increased humidity and southerly wind. Short range model guidance has trended toward slightly more instability available for the development of showers and thunderstorms ahead of and along an approaching cold front later in the day. These will evolve from northwest to southeast. The coverage and intensity of storms will help to be determined by any sunshine we see in the warm sector, which is a factor in the instability. We also have a couple of other atmospheric ingredients in place to support storms becoming strong to possibly severe. It’ll be important to stay weather-aware during the day on Friday while this threat is present. Showers and storms will exit via the South Coast Friday evening as the front sweeps through the region, but the front will slow just offshore and a weak wave of low pressure is expected to slide eastward along it as we begin the weekend. This will delay complete clearing across much of our region, and where cloud cover is most extensive – to the south – we can see a period of rainfall skirt the South Coast region Saturday morning and/or midday. Other than a low chance of a pop-up diurnally-driven shower over inland locations Saturday afternoon, the bulk of the region will see dry weather with mild air and lowering humidity levels. Sunday and Monday both look like mainly fair weather days with weak surface high pressure in control, however a very weak trough at upper levels keeps the air up their just cold enough to support the potential for a pop-up shower or thunderstorm in isolated locations, favoring Sunday, so I am keeping this remote chance in the forecast, just in case.

TODAY: Sunshine followed by increasing clouds. Highs 75-82, coolest South Coast. Dew point near 60. Wind S to SE 5-15 MPH.

TONIGHT: Mostly cloudy. Showers arrive. Chance of a thunderstorm. Areas of fog. Lows 61-68. Dew point 60+. Wind S up to 10 MPH.

FRIDAY: Mostly cloudy to partly sunny. Showers linger in eastern areas early. Late-day showers and thunderstorms likely from northwest to southeast. Potential for strong to severe storms. Highs 78-85. Dew point peaking in upper 60s. Wind S to SW 10-20 MPH, higher gusts possible.

FRIDAY NIGHT: Partly to mostly cloudy. Any early showers / thunderstorms southeastern areas will move out. Patchy fog. Lows 60-67. Dew point near 60. Wind W up to 10 MPH.

SATURDAY: Lots of clouds morning to midday including the chance of light rain near the South Coast, then a sun / cloud mix including the slight chance of a pop-up afternoon shower over inland locations. Highs 75-82. Dew point falls below 60. Wind variable to E up to 10 MPH.

SATURDAY NIGHT: Mostly clear. Fog patches lower elevations. Lows 55-62. Dew point lower to middle 50s. Wind calm.

SUNDAY: Sunny start, then a sun / cloud mix. Slight chance of a pop-up shower or thunderstorm during the afternoon. Highs 77-84, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.

SUNDAY NIGHT: Clearing. Lows 58-65. Wind variable up to 10 MPH.

MONDAY: Sunny to partly cloudy. Remote chance of an isolated afternoon shower. Highs 78-85, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (JUNE 30 – JULY 4)

General pattern features weak northwesterly flow aloft and high pressure dominating the surface. Temperatures near to above normal with mainly dry weather other than slight chances for pop-up air mass showers or thunderstorms a couple days. A little more day-to-day detail as we get closer to the holiday period.

DAYS 11-15 (JULY 5-9)

Fairly benign pattern overall but a little more available moisture and a disturbance or two in the region can increase the shower and thunderstorm chance from time to time.

DAYS 1-5 (JUNE 24-28)

The low pressure wave that delivered additional rain to much of the region yesterday, especially southeastern areas, has departed with the exception of lingering cloud patches to cross the sky this morning, otherwise a drying westerly air flow and approaching high pressure means a fair weather day. Temperatures will be at seasonably warm levels with humidity lowering to comfortable levels as dew points fall from the 60s into the 50s. The next area of low pressure to contend with moves into the Great Lakes Thursday and across southern Ontario on Friday. Its warm front approaches our area later Thursday, increasing the cloud cover after a sunny start to the day. Showers associated with this front will cross the region Thursday night, and we’ll find ourselves in the warm sector of the low for much of the day Friday. The low’s cold front will then cross the region Friday late afternoon through mid evening, and will be the focal point for a broken to possibly more solid band of showers and thunderstorms. Similar to a recent system, wind shear is decent and instability is a bit lacking for this, so conditions overall are marginal for stronger storms to form, but it will be something we’ll need to watch closely during the day on Friday. The parent low moves into Atlantic Canada by early Saturday and the cold front will slow down as it exits the South Coast. A weak wave of low pressure moving along that front will keep some cloudiness in the region for Saturday morning, and we’ll have to watch for an area of showers that can brush the South Coast before a clearing trend takes over and sunshine becomes more dominant from midday on. Sunday, while surface high pressure keeps the region mainly dry, weak upper level low pressure will trigger just enough instability that a pop-up shower cannot be completely ruled out during the afternoon hours.

TODAY: Patchy clouds morning. Abundant sun midday on. Highs 76-83. Dew point falls into 50s. Wind W 5-15 MPH.

TONIGHT: Clear. Fog patches low elevations. Lows 56-63. Dew point lower to middle 50s. Wind W under 10 MPH.

THURSDAY: Sunshine followed by increasing clouds. Highs 75-82, coolest South Coast. Dew point near 60. Wind S to SE 5-15 MPH.

THURSDAY NIGHT: Mostly cloudy. Showers arrive. Chance of a thunderstorm. Areas of fog. Lows 61-68. Dew point 60+. Wind S up to 10 MPH.

FRIDAY: Mostly cloudy through mid morning with showers likely and a slight chance of a thunderstorm. Partly sunny midday to late afternoon. Mostly cloudy with showers and thunderstorms from northwest to southeast late afternoon into evening. Highs 78-85. Dew point in 60s. Wind S to SW 10-20 MPH.

FRIDAY NIGHT: Partly to mostly cloudy. Patchy fog. Lows 60-67. Dew point near 60. Wind W up to 10 MPH.

SATURDAY: Lots of clouds morning, then increasing sun. Highs 75-82. Dew point falls below 60. Wind variable up to 10 MPH.

SATURDAY NIGHT: Clear. Fog patches lower elevations. Lows 55-62. Dew point lower to middle 50s. Wind calm.

SUNDAY: Sunny start, then a sun / cloud mix. Slight chance of a pop-up shower during the afternoon. Highs 77-84, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (JUNE 29 – JULY 3)

One or two disturbances in the region during this time can help trigger a few showers and t-storms. Otherwise, the general pattern features northwesterly flow aloft, high pressure nearby at the surface, and mainly fair weather with near to slightly above normal temperatures.

DAYS 11-15 (JULY 4-8)

A similar pattern continues around Independence Day and into the following week. A couple shower and thunderstorm chances but dry most of the time. No major sustained heat indicated.

DAYS 1-5 (JUNE 23-27)

A frontal system draped across the region provides the avenue for another wave of low pressure moving along it today, prolonging the cloudy and showery weather, particularly over areas from I-95 / I-90 east and south. Some heavier downpours / thunderstorms will be included in this activity, especially early today, before we see a gradual diminishing of activity later on. Drier air moves in tonight with a clearing trend. High pressure builds in with fair weather for our region Wednesday. The next low pressure system we have to contend with moves into the Great Lakes Thursday and across southeastern Canada on Friday. This system will drag a warm front / cold front duo across our region Thursday night and Friday, providing our next period of unsettled weather. A little more detail needs to be worked out, but for now I expect a round or two of showers and embedded thunderstorms Thursday night and Friday morning, with an additional shower or thunderstorm chance Friday afternoon before the system exits the region. The cold front will sit not that far to our south to start the weekend Saturday, and this may allow some cloudiness to hang around for a while, but I am not looking for any additional rain as it stands now.

TODAY: Mainly cloudy. Episodes of rain with embedded heavier showers and possible thunderstorms, diminishing from northwest to southeast midday on. Highs 68-75. Dew point 60+. Wind variable up to 10 MPH becoming W 5-15 MPH later in the day.

TONIGHT: Clearing. Lows 55-62. Dew point falls to near 50. Wind W up to 10 MPH.

WEDNESDAY: Mostly sunny. Highs 76-83, coolest coast. Dew point 50s. Wind variable up to 10 MPH with coastal sea breezes.

WEDNESDAY NIGHT: Mostly clear. Low elevation fog patches. Lows 57-64. Dew point rising slowly through 50s. Wind S up to 10 MPH.

THURSDAY: Sun followed by clouds. Highs 75-82, coolest South Coast. Dew point near 60. Wind S to SE 5-15 MPH.

THURSDAY NIGHT: Mostly cloudy. Showers arrive. Chance of a thunderstorm. Areas of fog. Lows 61-68. Dew point 60+. Wind S up to 10 MPH.

FRIDAY: Variably cloudy. Showers and possibly a thunderstorm in the morning. Chance of a shower or thunderstorm in the afternoon. Highs 76-83. Dewpoint in 60s. Wind S to SW 10-20 MPH.

FRIDAY NIGHT: Partial clearing. Patchy fog. Lows 60-67. Dew point near 60. Wind W up to 10 MPH.

SATURDAY: Limited sunshine. Highs 73-80, coolest coast. Dew point sub-60. Wind variable to E up to 10 MPH.

DAYS 6-10 (JUNE 28 – JULY 2)

High pressure sits to the north and provides fair weather but a light off-the-ocean air flow on June 28. The June 29 through July 2 period looks dry most of the time, but a couple disturbances in the region can trigger a shower or thunderstorm from time to time. There will be some diurnal influence on these chances as well, so timing of disturbances will help determine chances and coverage of any activity. Temperatures somewhat variable, but not straying too far from normal.

DAYS 11-15 (JULY 3-7)

Pattern looks surface high pressure dominant with a northwesterly air flow at upper levels. Overall dry with temperatures near to slightly above normal. A couple disturbances can trigger passing showers and thunderstorms but it would be dry the vast majority of the time.

DAYS 1-5 (JUNE 22-26)

Unsettled weather will be with us early this week. You may not think this statement is accurate if you’re an early riser today, seeing some sunshine, but the clouds are quickly moving in from the west and we’ll lose the sunshine by mid morning to the west and late morning or midday to the east, followed not long after be periodic rainfall in response to the approach of the first of two waves of low pressure. We’ll see the most solid rain area move through this evening, which then breaks into showery patches later at night before a second wave of low pressure solidifies it and prolongs the wet weather in much of the region through midday Tuesday. After this, we’ll see a drying trend develop from northwest to southeast as the system begins to shift offshore. Dry air arrives Tuesday night and high pressure builds in with dry weather for Wednesday. This high will shift northeastward Thursday as low pressure moves into the Great Lakes from the southwest. The low’s warm front will approach our region, increasing the cloud cover by later Thursday, then bringing the chance of some additional rain Thursday night and into Friday morning. Based on current timing, we will enter the warm sector of the low for several hours before its cold front crosses the region later Friday. This set-up indicates a good chance of showers and thunderstorms, however timing, coverage, and intensity of potential storms will have to be determined as we get closer.

TODAY: Sun gives way to overcast west to east. Rain chances increase west to east this afternoon. Highs 71-78, coolest coast. Dew point heads for 60. Wind SE up to 10 MPH.

TONIGHT: Cloudy. Showers likely. Chance of a thunderstorm. Areas of fog. Lows 57-64. Dew point similar to temperature. Wind S up to 10 MPH.

TUESDAY: Mainly cloudy. Episodes of rain with embedded heavier showers and possible thunderstorms, diminishing from northwest to southeast midday on. Highs 68-75. Dew point 60+. Wind variable up to 10 MPH becoming W 5-15 MPH later in the day.

TUESDAY NIGHT: Clearing. Lows 55-62. Dew point falls to near 50. Wind W up to 10 MPH.

WEDNESDAY: Mostly sunny. Highs 76-83, coolest coast. Dew point 50s. Wind variable up to 10 MPH with coastal sea breezes.

WEDNESDAY NIGHT: Mostly clear. Low elevation fog patches. Lows 57-64. Dew point rising slowly through 50s. Wind S up to 10 MPH.

THURSDAY: Sun followed by clouds. Highs 75-82, coolest South Coast. Dew point near 60. Wind S to SE 5-15 MPH.

THURSDAY NIGHT: Mostly cloudy. Showers arrive. Areas of fog. Lows 61-68. Dew point 60+. Wind S up to 10 MPH.

FRIDAY: Variably cloudy. Showers and thunderstorms likely. Highs 76-83. Dewpoint in 60s. Wind S to SW 10-20 MPH.

DAYS 6-10 (JUNE 27 – JULY 1)

High pressure builds in with fair weather June 27-28 weekend. Frontal system brings a shower chance June 29 before high pressure returns with fair weather to finish the month of June and start off July. Temperatures generally close to seasonal normals.

DAYS 11-15 (JULY 2-6)

Pattern looks surface high pressure dominant with a northwesterly air flow at upper levels. Overall dry with temperatures near to slightly above normal. A couple disturbances can trigger passing showers and thunderstorms but this would be the exception over the rule.

COMMENTARY

Summer has arrived! The solstice occurred at 4:24 a.m. EDT this morning. Many times media is quick to jump on the fact that the length of daylight starts to decrease from here on. Drama. Yes, we start heading in the other direction, but the sunsets are still late and the sunrises are still early and the change is very, very slow to start occurring, to the point of not really being noticeable for a few weeks, and then only slightly so for a few more before we finally really start to see it later in the summer. If you thrive on the long daylight, yes we are at peak, and we’ve had a long journey to get here, and we’re only at the mountain top. The journey back down is a slope, not a cliff. Enjoy the long daylights we still have for quite some time to come and don’t worry about the rest of the media throws at you! 🙂 Also, Happy Father’s Day to any dad reading this!

DAYS 1-5 (JUNE 21-25)

Elongated low pressure remains over eastern Canada with a broad upper trough over the US Northeast. This is the same overall set-up that brought us the pleasant but gusty day yesterday, but with isolated showers and thunderstorms popping up in the afternoon to early evening. The difference today is that the surface pressure gradient loosens up and the wind will be less busy. While we have a pleasantly mild, low humidity day again, we do have to keep an eye out for isolated to scattered showers and thunderstorms this afternoon, which will dissipate by about sunset. Not everybody sees these. Many areas will be rain-free all day. Areas that do get hit will have many dry hours with only a brief interruption. So overall it’s another nice day just with the need to keep an eye to the sky if you have any outdoor plans! Low pressure heads our way on Monday bringing a more widespread rainfall into the region favoring the midday through evening hours. This low pressure system will be stretched by the upper air pattern, and as it becomes somewhat parallel to the upper flow, it will be slow to migrate eastward enough to exit. This means that a shower and thunderstorm chance will exist later Monday night into part of Tuesday, particularly for southern and eastern portions of the WHW forecast area, before the system fully pulls offshore and drier weather returns. High pressure builds in with fair weather Tuesday night and Wednesday. As this high starts to move away, we’ll see some clouds increasing on Thursday ahead of our next approaching low pressure system, but as of now I think we’ll get through that day mainly rain-free. One thing we will be lacking in these early summer days: heat.

TODAY: Abundant sun morning. Sun / cloud mix afternoon with isolated showers and thunderstorms mid afternoon to early evening. Highs 75-82. Dew point sub-60. Wind W 5-15 MPH becoming variable up to 10 MPH with coastal sea breeze potential in the afternoon.

TONIGHT: Clearing evening. Increasing clouds overnight. Lower elevation fog patches. Lows 55-62. Dew point near 55. Wind calm.

MONDAY: Becoming cloudy. Rain arrives southwest to northeast midday on. Highs 70-77, coolest coast. Dew point heads to 60+. Wind SE up to 10 MPH.

MONDAY NIGHT: Cloudy. Showers likely. Chance of a thunderstorm. Areas of fog. Lows 57-64. Dew point similar to temperature. Wind S up to 10 MPH.

TUESDAY: Variably cloudy through midday with a shower and thunderstorm chance, highest from the I-95 belt eastward. Increasing sun later west to east. Highs 72-79. Dew point 60+ falling back to 50s by late day. Wind variable to W 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Lows 55-62. Dew point near 50. Wind W up to 10 MPH.

WEDNESDAY: Mostly sunny. Highs 74-81, coolest coast. Dew point 50s. Wind variable up to 10 MPH with coastal sea breezes.

WEDNESDAY NIGHT: Partly cloudy. Low elevation fog patches. Lows 57-64. Dew point rising slowly through 50s. Wind S up to 10 MPH.

THURSDAY: Partly sunny. Highs 78-85, coolest South Coast. Dew point near 60. Wind S 5-15 MPH.

DAYS 6-10 (JUNE 26-30)

Trough and frontal system brings a shower and thunderstorm chance through the region on June 26. High pressure builds in with fair weather June 27-28 weekend. Frontal system brings a shower chance June 29 before high pressure returns with fair weather to finish the month of June. Temperatures show typical early summer variability but average close to normal overall.

DAYS 11-15 (JULY 1-5)

Pattern looks surface high pressure dominant with a northwesterly air flow at upper levels. Overall dry with temperatures near to slightly above normal. Caveats: Beyond day 10 so confidence level is naturally lower. Always need to watch for quick-moving “over the top” disturbances in a northwesterly air flow.

DAYS 1-5 (JUNE 20-24)

Today is the last full day of astronomical spring, as we welcome summer with the occurrence of the solstice at 4:24 a.m. EDT Sunday. This weekend will feature weather that feels a little more like spring than summer, courtesy a broad upper trough over our region and a surface low spinning about in eastern Canada. Both days will feature a mix of sun and clouds as sun-heated land sends moisture upward into colder air aloft, prompting diurnal cloud development. Some of these clouds can grown adequately to produce showers and even an isolated thunderstorm. Activity will favor the 3 p.m. to 7 p.m. time frame each day and the most likely areas to see it are southern NH and northeastern MA today, and anywhere in the region on Sunday but still focused higher chances in southern NH and eastern MA. Today’s wind will be similar to yesterday’s – an active westerly breeze with gusts, but it will diminish later in the day. Sunday’s wind will be less active as the surface pressure gradient loosens up. The biggest take-aways from the weekend forecast: Low humidity, lack of heat, and dry the vast majority of the time. Just keep an eye out if you have late-day plans for any showers that may be in the area. We then turn our attention to a wave of low pressure moving into the Northeast on Monday, and this brings us the chance of a widespread, somewhat beneficial rainfall. Guidance has been showing somewhat differing solutions for this event, with some bringing in a widespread moderate rain event, and some shunting the brunt to our south with a lighter event or even a partial miss. You’ve heard it a million times here: “When in drought, leave it out”. Well, I’m not leaving it out, per say, but I am leaning toward a fairly widespread but not-too-beneficial event with light to moderate rainfall amounts from a system that moves in during Monday, peaks in the evening, and exits during the early hours of Tuesday. During that day we’ll see quick drying with a clearing trend. Previously, I’d been eyeing a potential system for more unsettled weather on Wednesday, but I am leaning away from that in favor of weak high pressure keeping us dry that day.

TODAY: Sun/cloud mix. Isolated to scattered mid afternoon to early evening showers possible, mainly southern NH and northeastern MA. Highs 75-82. Dew point near 50. Wind W 10-20 MPH, higher gusts, diminishing late in the day.

TONIGHT: Partly cloudy. Lows 55-62. Dew point near 50. Wind W up to 10 MPH.

SUNDAY: Sun/cloud mix. Scattered showers and a possible thunderstorm from mid afternoon to early evening. Highs 74-81. Dew point in 50s. Wind W up to 10 MPH but coastal sea breezes possible.

SUNDAY NIGHT: Partly cloudy evening. Mostly cloudy overnight. Lows 55-62. Dew point near 50. Wind SE up to 10 MPH.

MONDAY: Cloudy. Rain arrives southwest to northeast. Highs 68-75, coolest coast. Dew point rises to near 60. Wind E 5-15 MPH.

MONDAY NIGHT: Cloudy. Rain in the evening. Areas of fog. Lows 57-64. Dew point around 60. Wind variable under 10 MPH.

TUESDAY: Increasing sun. Highs 72-79. Wind W 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Lows 55-62. Wind W up to 10 MPH.

WEDNESDAY: Partly cloudy. Highs 74-81, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (JUNE 25-29)

Unesttled weather potentials June 25-26 and end of period, otherwise fair weather much of the time. Temperatures variable but averaging close to normal.

DAYS 11-15 (JUNE 30 – JULY 4)

West northwest flow and a couple disturbances with short-lived unsettled threats, Otherwise, mainly dry. Temperatures near to slightly above normal.

DAYS 1-5 (JUNE 19-23)

The next three days, we’ll sit south of low pressure in eastern Canada, which will slightly drift its way southward. Another low pressure wave slides southeast of our region today, and this will toss some high clouds across the sky, filtering the sun. Some fair-weather clouds pop up during the day as well. As high pressure builds to our south behind the departing low pressure wave, the surface pressure gradient between it and the low to the north will generate a gusty westerly breeze today which continues Saturday before diminishing late in the day. We’ll see additional pop-up “mostly” fair weather clouds Saturday, but I cannot 100% rule out a spot shower especially over the hills to the north and west of Boston. Sunday’s weather will feature less wind but more clouds eventually popping and this prompts me to add the chance of scattered showers and even a possible thunderstorm to the forecast that afternoon and early evening. Even with that, the majority of the day at any given location will feature rain-free conditions. The summer solstice occurs at 4:24 a.m. EDT Sunday. Monday we watch a wave of low pressure that has a decent shot at bringing a more widespread rainfall to the region. Over the next couple days, fine-tuning the low’s expected track will help with forecast details for this system, which will depart Tuesday when we see fair weather return.

TODAY: Sun/cloud mix. Highs 76-83. Dew point in 50s. Wind W increase to 10-20 MPH, higher gusts.

TONIGHT: Mostly clear. Lows 54-61. Dew point near 50. Wind W 5-15 MPH, a few higher gusts.

SATURDAY: Sun/cloud mix. Isolated afternoon showers possible generally central MA & southern NH. Highs 75-82. Dew point near 50. Wind W 10-20 MPH, higher gusts, diminishing late in the day.

SATURDAY NIGHT: Mostly clear. Lows 55-62. Dew point near 50. Wind W up to 10 MPH.

SUNDAY: Sun/cloud mix. Scattered showers and a possible thunderstorm from mid afternoon to early evening. Highs 74-81. Dew point in 50s. Wind W up to 10 MPH but coastal sea breezes possible.

SUNDAY NIGHT: Clouding up. Lows 55-62. Dew point near 50. Wind SE up to 10 MPH.

MONDAY: Cloudy. Chance of rain. Highs 66-73, coolest coast. Dew point rises to near 60. Wind E 5-15 MPH.

MONDAY NIGHT: Cloudy. Rain in the evening. Areas of fog. Lows 57-64. Dew point around 60. Wind variable under 10 MPH.

TUESDAY: Increasing sun. Highs 72-79. Wind W up to 10 MPH.

DAYS 6-10 (JUNE 24-28)

Shower threats June 24 and late June 25 into early June 26 based on current timing. Fair otherwise. Temperatures variable but averaging close to normal.

DAYS 11-15 (JUNE 29 – JULY 3)

West northwest flow and a couple disturbances with short-lived unsettled threats, Otherwise, mainly dry. Temperatures near to slightly above normal.

DAYS 1-5 (JUNE 18-22)

Low pressure passing north of our region today will drag a warm front across the region first, followed by a cold front. The warm front will produce a couple rounds of showers with possible embedded thunder. One or two clusters or lines of thunderstorms can be expected later today from west to east with the cold front and possible pre-frontal trough. There are some competing negative and positive factors with regard to the chance of severe storms. Negative factors, against severe weather, include lack of sun in the warm sector (between the two fronts) and limited instability. Positive factors, in favor of severe weather, include abundant potential energy and notable wind shear. The latter can enable individual storms to rotate, which would increase tornado potential if we were to get an organized storm not part of a solid line. A more linear set-up can still result in strong to damaging straight-line wind gusts. Odds favor this activity occurring mostly north of I-90, but all of the region should be weather-aware this afternoon should any of this potential be realized. Even without storm-caused wind gusts, we will have a pretty active southerly wind developing today. The threat comes to an end rather quickly this evening as the cold front sweeps through and drier air arrives. Friday’s weather features a gusty westerly wind, seasonable warmth but dry air, and somewhat limited sun as an area of low pressure passes to our south, sending its high cloud shield across the sky, while there are also some pop-up fair weather clouds. Saturday will feature additional fair-weather clouds, though I believe any pop-up showers stay to our north. Sunday, some high cloudiness makes a return ahead of the next approaching low pressure area, but also additional fair weather clouds will pop-up, but again any showers that develop should stay to the north. There will be a slight cooling trend Saturday and Sunday, and humidity levels will remain comfortably low. A gusty breeze remains active Saturday but diminishes later in the day, and lighter winds are expected on Sunday. We welcome summer with the occurrence of the solstice at 4:24 a.m. on Sunday. The aforementioned low pressure area is expected to bring an overcast sky and a rain chance for Monday, but the details including timing and rain coverage and intensity are to be determined.

DAYS 6-10 (JUNE 23-27)

Shower threats June 24 and late June 25 into early June 26 based on current timing. Fair otherwise. Temperatures variable but averaging close to normal.

DAYS 11-15 (JUNE 28 – JULY 2)

West northwest flow and a couple disturbances with short-lived unsettled threats, Otherwise, mainly dry. Temperatures near to slightly above normal.

DAYS 1-5 (JUNE 17-21)

We have another nice day in store for today but there will be some varying amounts of high and mid level cloud cover to limit the sun. A disturbance approaches from the west and while it can trigger a few showers and thunderstorms to our west later today that activity is expected to dissipate before arriving. Overnight light rain approaches as a warm front begins its trek across the region, one that will produce additional showers and perhaps some embedded thunder in our area during Thursday morning. We enter the warm sector of low pressure passing to our north Thursday afternoon, and a trough and cold front will then move through the region, being focus points for showers and thunderstorms. While a lack of sun and marginal instability are negative factors, there is some potential for a few strong storms with the help of a couple other positive factors, including decent wind shear, which could allow any established storms to become super cells and rotate. While this probability is not extreme, it’s enough that we should pay close attention until the storm threat passes and ends in the evening. So, be weather-aware Thursday, just in case. Behind this what is a three day weekend for many (Friday through Sunday) looks quite nice. We will see some breezy conditions at times between low pressure to our northeast and high pressure building from the Ohio Valley to the Mid Atlantic especially Friday and Saturday. Both of those days will also see some passing fair weather clouds, but I strongly suspect any pop-up showers will be confined to the mountains to our north. Sunday, we’ll see some high clouds fanning across the sky in advance of our next wet weather threat, but that will hold off easily for a dry day and evening to finish the weekend! Heat and humidity will be absent during this stretch as well, making it quite pleasant for outdoor activities. We welcome summer with the occurrence of the solstice at 4:24 a.m. on Sunday.

TODAY: Sun / cloud mix. Highs 76-83, coolest South Coast. Dew point rising toward 60. Wind S 5-15 MPH.

DAYS 6-10 (JUNE 22-26)

Active pattern next week. Rain threat June 22. Shower threat June 24. T-storm threat June 26. Temperatures variable but averaging close to normal.

DAYS 11-15 (JUNE 27 – JULY 1)

Quieter pattern here. West northwest flow and a couple disturbances with short-lived unsettled threats, Otherwise, mainly dry. Temperatures near to slightly above normal.

DAYS 1-5 (JUNE 16-20)

The final full five days of astronomical spring span this forecast period, and we have some nice weather much of the time, with one interruption. We start with fair weather today as high pressure slides well south of us, across the Mid Atlantic Coast, while a quasi-stationary low pressure area sits in Atlantic Canada. After a cool start, it will warm to seasonable levels, but the coast ends up coolest this afternoon as a weakening westerly wind flow allows sea breezes to eventually develop – but a very nice day overall! Decorative cirrus cloud patches are visible in the northwestern and northern sky to start the day today, but in general we’ll see unlimited sunshine. More cloud cover will be present on Wednesday as a disturbance closes in from the west. This may trigger a shower or thunderstorm in western New England later in the day but I suspect none of that activity will survive to reach the WHW forecast area. However, clouds will thicken up ahead of a warm front Wednesday night with rain chances increasing overnight. Low pressure crossing the Great Lakes and heading for the St. Lawrence Valley will pull that front and its attendant rainfall through the region into Thursday morning before we emerge into the low’s warm sector. This is when we’ll see a spike in humidity and then have to watch for showers and thunderstorms as the low’s cold front approaches and passes through the region. Thursday’s shower and storm potential does have to be watched as there will be some ingredients for severe storms in place. However, this no longer appears as if it will be an optimal set-up for severe storms due to the lack of sunshine in the warm sector and also the best instability remaining to the west and south of the WHW forecast area. It still bears watching, however. Whatever showers and storms do occur will move out that evening as the cold front moves through and offshore. This sets up dry, breezy, but pleasant weather for late this week with a west to northwest air flow via Canada and the Great Lakes.

TODAY: Mostly sunny. Highs 77-84 except cooler South Coast / Cape Cod. Dew point upper 50s. Wind W 5-15 MPH, diminishing to under 10 MPH with developing coastal sea breezes this afternoon.

TONIGHT: Mostly clear. Lows 56-63. Dew point lower to middle 50s. Wind SW up to 10 MPH.

WEDNESDAY: Sun followed by clouds. Highs 76-83, coolest South Coast. Dew point rises toward 60. Wind S 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Showers arrive overnight west to east. Fog patches form pre-dawn. Lows 61-68. Dew point 60+. Wind S 5-15 MPH.

THURSDAY: Mostly cloudy with early showers likely, then variably cloudy with potential showers and thunderstorms in the afternoon. Highs 76-83. Dew point rises to near 70. Wind SW 10-20 MPH, gusts 25-35 MPH.

THURSDAY NIGHT: An early shower or thunderstorm toward Cape Cod otherwise clearing. Fog patches evening. Lows 56-63. Dew point falls to 50s. Wind SW shifting to NW 5-15 MPH.

FRIDAY: Sun and passing clouds. Highs 76-83. Dew point near 50. Wind NW 5-15 MPH, higher gusts.

FRIDAY NIGHT: A few clouds, then clear. Lows 55-62. Dew point near 50. Wind NW up to 10 MPH.

SATURDAY: Sun and passing clouds. Highs 75-82. Dew point near 50. Wind NW 5-15 MPH.

DAYS 6-10 (JUNE 21-25)

Fair weather continues to finish the weekend as we welcome summer on June 21 (solstice 4:24 a.m. EDT). Wet weather potentials June 22 & 24 with fair weather June 23 & 25. No significant heat in sight.

DAYS 11-15 (JUNE 26-30)

Home stretch of June expected to feature a west northwest flow / progressive pattern with a couple shower and t-storm chances from passing disturbances, otherwise mostly fair weather and variable but mostly fairly close to normal temperatures.

DAYS 1-5 (JUNE 15-19)

A cold front exits, stage-right (i.e., offshore to the east) early this morning, taking the last of its showers and thunderstorms with it, and then clouds give way to plenty of sun as drier air arrives during today. High pressure slides just south of the region Tuesday with fair and pleasant weather. Dry weather continues Wednesday but you’ll notice an increase in high cloudiness in response to low pressure heading into the Great Lakes with its warm front extending out from it and approaching our region. That front will thicken the clouds up Wednesday night when a shower or thunderstorm can occur as more humid air arrives. As the low passes to our north on Thursday, its trailing cold front, and probably a pre-frontal trough, will sweep across our region, acting on the warm, humid air in place. This will trigger a round or two of showers and thunderstorms, and there is some potential for severe weather to occur. Updates will fine-tune that part of the forecast over the next couple of days. Behind this front will come a cooler, drier Canadian air mass for Friday with an active breeze and a mix of sunshine and clouds that day.

TODAY: A shower or thunderstorm possible far eastern areas, especially southeastern NH and Cape Cod, early in the day, then clouds give way to sun. Highs 78-85. Dew point drops to 50s. Wind NW 5-15 MPH.

TONIGHT: Mostly clear. Lows 55-62. Dew point lower 50s. Wind W under 10 MPH.

TUESDAY: Mostly sunny. Highs 77-84 except cooler South Coast / Cape Cod. Dew point upper 50s. Wind W to SW 5-15 MPH.

TUESDAY NIGHT: Clear. Lows 56-63. Dew point lower to middle 50s. Wind SW up to 10 MPH.

WEDNESDAY: Sun followed by clouds. Highs 76-83, coolest South Coast. Dew point rises toward 60. Wind S 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy. A shower or thunderstorm possible. Fog patches form. Lows 63-70. Dew point 60+. Wind SW 5-15 MPH.

THURSDAY: Variably cloudy. Showers and thunderstorms likely. Highs 76-83. Dew point rises to near 70. Wind SW 10-20 MPH, higher gusts possible.

THURSDAY NIGHT: Any showers / thunderstorms end, followed by clearing. Fog patches through evening. Lows 56-63. Dew point falls to 50s. Wind SW shifting to NW 5-15 MPH.

FRIDAY: Sun and passing clouds. Highs 76-83. Dew point near 50. Wind NW 5-15 MPH, higher gusts.

DAYS 6-10 (JUNE 20-24)

Fair, pleasant weekend weather June 20-21. The summer solstice occurs at 4:24 a.m. EDT on June 21. Humidity, clouds, and shower chances may increase from the early to middle portion of next week as the air flow turns more southerly and a trough approaches from the west.

DAYS 11-15 (JUNE 25-29)

West to northwest air flow with one or two disturbances causing passing shower / t-storm chances, otherwise a fairly dry pattern sets up with somewhat changeable but generally seasonably warm temperatures.

DAYS 1-5 (JUNE 14-18)

The heat and humidity will tick-up over yesterday a little, but the latter will not be to the level of what we experienced Thursday and Friday of this week, and a ventilating breeze will also make it more tolerable outside today. We stay rain-free through the daylight hours and into the evening, with shower and thunderstorm chances increasing late evening into overnight from west to east with a passing cold front. This front will move offshore early Monday with a lingering shower possible in the eastern coastal plain early. Otherwise look for a cooler, dry day with a breeze and a sun / cloud mix. High pressure slides south of the region with fair and seasonably warm weather Tuesday, though humidity levels remain fairly low. Clouds increase Wednesday ahead of an approaching warm front as low pressure heads into the Great Lakes, but I do expect our day to be rain-free, seasonably warm, and becoming moderately humid. Thursday’s weather is the most interesting and potentially volatile of this 5-day period as we will have a vigorous surface moving from the Great Lakes to southeastern Canada, and a vigorous upper trough moving into our region. With the arrival of warm, humid, unstable air, the stage is set for showers and thunderstorms, with the potential for some severe weather. With it being “day 5”, obviously it’s not a highest confidence forecast, but the signs are there already and I feel it’s important to note it now, and obviously update the outlook as we get closer to that day.

TODAY: Sun filtered to interrupted by variable high and mid level clouds. Highs 85-92 except 77-84 South Coast / Cape Cod. Dew point rises above 60. Wind S 5-15 MPH, gusts around 20-25 MPH, strongest on the South Coast.

TONIGHT: Mostly cloudy. A good chance of showers with possible thunderstorms from west to east late evening and overnight. Fog patches in sheltered locations. Lows 62-69. Dew point 60+. Wind SW 5-15 MPH, higher gusts possible especially around any storms.

MONDAY: Early clouds with a shower potential especially eastern coastal areas, then a sun / cloud mix. Highs 77-84. Dew point falls into 50s. Wind NW 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 56-63. Dew point lower 50s. Wind W under 10 MPH.

TUESDAY: Mostly sunny. Highs 78-85 except cooler South Coast / Cape Cod. Dew point upper 50s. Wind W to SW 5-15 MPH.

TUESDAY NIGHT: Clear. Lows 57-64. Dew point middle to upper 50s. Wind SW up to 10 MPH.

WEDNESDAY: Sun followed by clouds. Highs 79-86, coolest South Coast. Dew point 60+. Wind S 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy. A shower possible. Lows 63-70. Dew point 60+. Wind SW 5-15 MPH.

THURSDAY: Variably cloudy. Showers and thunderstorms likely. Highs 76-83. Dew point rises to near 70. Wind SW 10-20 MPH, higher gusts possible.

DAYS 6-10 (JUNE 19-23)

The June 19-21 period features fair weather, starting cooler and drier with a breeze followed by a warming trend. The summer solstice occurs at 4:24 a.m. EDT on June 21. Higher humidity along with shower and thunderstorm chances June 22-23.

DAYS 11-15 (JUNE 24-28)

Leaning toward a wet weather opportunity with a passing trough early period followed by a drier west to northwest flow and seasonably warm weather.

DAYS 1-5 (JUNE 13-17)

A stellar weekend, book-ended by cold fronts – the first of which is moving offshore starting this morning with a band of clouds lingering over southeastern MA, but the day will turn out basically sunny across the region and while it will be on the very warm to hot side, it will be much more comfortable in comparison to yesterday as dew points drop into the 50s behind the front. The relatively dry air will stay in place into Sunday before the humidity does come up a little bit later in the day, ahead of the next approaching cold front. This front will send cloudiness into our region, limiting the sun as the day goes on, but a shower and thunderstorm threat will hold off until night, arriving from west to east across the region at that time. This front will move through the region overnight and offshore early Monday, bringing another cooler, drier Canadian air mass into our region for Monday and Tuesday as well, though we’ll warm a little bit more Tuesday afternoon as an area of high pressure slides to our south, and further still on Wednesday as the high sits offshore. A warm front approaching the region may bring some clouds in by later Wednesday, but I expect that day to still be dry and comfortable.

TODAY: Early clouds southeastern MA, otherwise sunny. Highs 84-91. Dew point falls into 50s. Wind NW 5-15 MPH, a few higher gusts.

TONIGHT: Mostly clear. Lows 60-67. Dew point sub-60. Wind W up to 10 MPH.

SUNDAY: Sun filtered by high clouds. Highs 85-92 except 77-84 South Coast / Cape Cod. Dew point creeps back over 60 by late-day. Wind S 5-15 MPH, a few higher gusts possible.

SUNDAY NIGHT: Mostly cloudy. A good chance of showers with possible thunderstorms from west to east. Fog patches. Lows 62-69. Dew point 60+. Wind SW 5-15 MPH, higher gusts possible especially around any storms.

MONDAY: Early clouds with a shower potential especially east, then a sun / cloud mix. Highs 77-84. Dew point falls into 50s. Wind NW 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 56-63. Dew point lower 50s. Wind W under 10 MPH.

TUESDAY: Mostly sunny. Highs 78-85 except cooler South Coast / Cape Cod. Dew point upper 50s. Wind W to SW 5-15 MPH.

TUESDAY NIGHT: Clear. Lows 57-64. Dew point middle to upper 50s. Wind SW up to 10 MPH.

WEDNESDAY: Sun followed by clouds. Highs 79-86, coolest South Coast. Dew point 60+. Wind S 5-15 MPH.

DAYS 6-10 (JUNE 18-22)

Watching June 18 for a spike of high humidity and a thunderstorm potential as low pressure passes to our north. Cooler, drier weather end of week, warming over the June 20-21 weekend and beyond. The Summer Solstice occurs at 4:24 a.m. EDT June 21.

DAYS 11-15 (JUNE 23-27)

Continued mixed signals and inconsistencies in guidance out this far. Still leaning toward a progressive pattern with a couple disturbance bringing shower / thunderstorm chances and air mass changes.

DAYS 1-5 (JUNE 12-16)

High humidity remains in place today while a weak back-door cold front makes a visit from the northeast into southeastern NH and eastern MA, perhaps as far south and west and northern RI later in the day. A very weak disturbance is passing by aloft while this is all taking place. These ingredients bring the chance for some pop up showers and thunderstorms, though I do not expect coverage to be very high. We have a few showers to start today already in south central NH and a few southwest of Boston, but most of them will fade as the disturbance triggering them remains weak. The back-door frontal boundary can help trigger a few more as we move through the day, but again I would expect these to be isolated. Further west, outside of the front’s influence, a couple air mass showers and storms can also pop up. Bottom line for today: You’ll probably stay dry, but keep an eye to the sky (and on the radar) just in case. Inland is hottest while the coast gets some relief, but humidity is up regionwide, so muggy regardless. Tonight, a weakening frontal boundary moves through from west to east, but I only expect a couple of showers and thunderstorms to be possible as it moves through, with many areas missing out on those. The passage of this front does bring lower humidity for the weekend, especially Saturday when we have a northwest breeze transporting some Canadian air into the region. This is modified air, however, so it will still be quite a warm day. Sunday, high pressure shifts offshore and our wind turns southerly ahead of an approaching cold front, so the humidity levels tick up just a tad, but remain below oppressive levels. The southerly breeze will be active at times which will help help counteract the warmth and moderate humidity if you’re outside. The shower and thunderstorm threat increase from west to east at night as the front moves through the region, then offshore by early Monday when a shower can linger in far eastern areas to start the day. We’ll experience a cooler, drier northwesterly air flow behind the front on Monday, and a westerly breeze with moderating temperatures on Tuesday as high pressure slides to our south. Previous ideas about a wave of low pressure passing by to the south that day have shifted and that system would be well out to sea with a more progressive high sliding off the Mid Atlantic Coast at that time.

TODAY: Variably cloudy. A shower or thunderstorm possible – favoring south central NH early in the day, and favoring areas mostly west of I-95 in the afternoon but low coverage with most areas staying rain-free. Highs 77-84 coastal plain, 85-92 inland with warmest in central MA to southwestern NH. Dew point 65+. Wind variable to E 5-15 MPH coastal plain eastern MA & NH, SW up to 10 MPH further inland areas.

TONIGHT: Partly cloudy early, then mostly cloudy late evening and overnight with a shower or thunderstorm possible from west to east. Lows 63-70. Dew point 60+. Wind variable to S up to 10 MPH.

SATURDAY: Sun and passing clouds. Highs 82-89. Dew point falls below 60. Wind W to NW 5-15 MPH, a few higher gusts possible.

SATURDAY NIGHT: Mostly clear. Lows 60-67. Dew point sub-60. Wind W up to 10 MPH.

SUNDAY: Sun filtered by high clouds. Highs 84-91 except 77-84 South Coast / Cape Cod. Dew point creeps back over 60 by late-day. Wind S 5-15 MPH, a few higher gusts possible.

SUNDAY NIGHT: Mostly cloudy. A good chance of showers with possible thunderstorms from west to east. Fog patches. Lows 62-69. Dew point 60+. Wind SW 5-15 MPH, higher gusts possible especially around any storms.

MONDAY: Early clouds with a shower potential especially east, then a sun / cloud mix. Highs 78-85. Dew point falls into 50s. Wind NW 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 56-63. Wind W under 10 MPH.

TUESDAY: Partly sunny. Highs 80-87 except cooler South Coast / Cape Cod. Wind W to SW 5-15 MPH.

DAYS 6-10 (JUNE 17-21)

Fair June 17 but clouds increase ahead of a warm front, which passes by early June 18 and sets up a shower and thunderstorm chance prior to the passage of a cold front as low pressure travels north of the region. Fair, breezy, cooler weather follows it June 19 then high pressure dominates with fair weather and a slow warming trend on the June 20-21 weekend. The Summer Solstice occurs at 4:24 a.m. EDT June 21.

DAYS 11-15 (JUNE 22-26)

Mixed signals from guidance and the pattern is a little hard to define in the early days of astronomical summer as we head into late June. I do see the tendency for a somewhat progressive pattern, and one or two disturbances bringing shower and thunderstorm chances. One question to answer is if a mid period low pressure wave brings us a shot of more substantial rainfall. Many details to-be-determined.
