Saturday Forecast

9:39AM

DAYS 1-5 (AUGUST 20-24)…
High pressure east of the region sends a weak marine flow into the region into an existing seasonable August air mass. This takes the early morning clouds and breaks them up but also creates diurnal clouds to mix with the sun. The only clouds that may grow enough to produce an isolated shower would need help from hills and mountains well west and northwest of Boston, but any of these would be brief. Cloudiness reforms tonight in the lower levels and breaks up again Sunday, but more substantial cloudiness will advance from west to east later in the day as well as some lower cloudiness returning from the south as the moisture level increases ahead of a cold front. This front will cross the region west to east in the early hours of Monday, probably with a band of non-beneficial showers. Monday’s daytime weather will be dry and cooler with a gusty breeze and a sun/cloud mix as a refreshing air mass arrives from Canada. Tuesday and Wednesday will feature sunshine and a slow warm-up as high pressure dominates.
TODAY: Partly to mostly sunny. Patchy fog early. Isolated afternoon shower possible hills far west and north of Boston. Highs 78-88, coolest coastal areas. Wind light variable with sea breezes.
TONIGHT: Partly to mostly cloudy. Patchy fog late. Lows 60-68, warmest urban areas. Wind light variable.
SUNDAY: Partly to mostly cloudy. Patchy fog early. Chance of showers late in the day mainly south and west of Boston. Increasingly humid. Highs 76-86, coolest coastal areas. Wind SE to S 5-15 MPH.
SUNDAY NIGHT: Mainly cloudy. Band of showers moving west to east across the region. Humid. Lows 60-68. Wind S 10-20 MPH and gusty, shifting to W behind the showers.
MONDAY: Sun and passing clouds. Drying out. Highs 75-82. Wind NW 10-20 MPH with higher gusts.
TUESDAY: Mostly sunny. Lows 60-68. Highs 78-86.
WEDNESDAY: Mostly sunny. Lows 60-68. Highs 80-88.

DAYS 6-10 (AUGUST 25-29)…
Other than a few isolated showers around the August 27-28 weekend with a dissipating front in the region, mainly dry and warm to hot weather is expected.

DAYS 11-15 (AUGUST 30-SEPTEMBER 3)…
A lower than average confidence forecast at this time. Leaning toward a few episodes of isolated to scattered showers with continued above normal temperatures.

Friday Forecast

2:17AM

DAYS 1-5 (AUGUST 19-23)…
High pressure builds over the region today and holds through Saturday with generally fair weather, but there may be enough moisture along a sea breeze front to pop an isolated shower near the South Coast today and then develop some low cloudiness and patchy fog tonight and again Saturday night, which will burn off each morning following, though a little more slowly in some locations on Sunday. And during Sunday, we’ll see the approach of a front from the west which will cause some increase in cloudiness again by the end of the day. However, it now appears that this front will be more progressive than I had been thinking, and it will likely end up producing a largely insignificant rain event in the form of scattered to general showers for a few hours during the early hours of Monday. After that, high pressure builds back in with more day weather, though the transition on Monday may feature some gusty wind as it dries out.
TODAY: Mostly sunny to partly cloudy. Remote risk of an isolated shower in the afternoon near the South Coast. Highs 80-88, coolest along the shoreline areas. Wind light variable with coastal sea breezes developing.
TONIGHT: Partly to mostly cloudy. Patchy fog overnight. Lows 60-68, warmest urban areas. Wind light variable.
SATURDAY: Partly to mostly sunny. Patchy fog early. Highs 78-88, coolest coastal areas. Wind light variable with sea breezes.
SATURDAY NIGHT: Partly to mostly cloudy. Patchy fog late. Lows 60-68, warmest urban areas. Wind light variable.
SUNDAY: Partly to mostly cloudy. Patchy fog early. Chance of showers late in the day. Highs 76-86, coolest coastal areas. Wind SE to S 5-15 MPH.
MONDAY: Mostly cloudy in the morning with showers ending west to east. Partly cloudy and windy afternoon. Lows 60-68, warmest urban areas. Highs 77-85.
TUESDAY: Mostly sunny. Lows 60-68, warmest urban areas. Highs 78-86.

DAYS 6-10 (AUGUST 24-28)…
Fair and warming weather is expected August 24-26. A weakening front late in the period may result in a few showers but no sign of widespread rain.

DAYS 11-15 (AUGUST 29-SEPTEMBER 2)…
Watch for a tropical storm or hurricane possibly offshore of the US East Coast sometime in the August 29-31 period. During that time the weather here should be largely rain-free with above normal temperatures. A weak front may bring a few showers somewhere in the first couple days of September with continued above normal temperatures.

Thursday Forecast

9:06AM

DAYS 1-5 (AUGUST 18-22)…
Let’s get something out of the way first. There is NO lunar eclipse tonight. That’s fake news. Now back to the weather. A disturbance passing south of New England this morning brings a few showers to southeastern MA, and a cold front approaching the region late in the day trigger an isolated shower or thunderstorm. High pressure moves in and dominates the weather Friday through most of the weekend. Another front moves in from the west and brings the risk of showers and thunderstorms by Sunday night and more likely Monday.
TODAY: Cloudiness and a few showers southeastern MA mid morning with increasing sun elsewhere and then there. Becoming partly cloudy this afternoon with a slight risk of isolated showers and thunderstorms. More humid. Highs 79-84 South Coast, 85-90 elsewhere. Wind W to SW 5-15 MPH, SE at times near the shore.
TONIGHT: Partly cloudy. Less humid. Lows 60-68, warmest urban areas. Wind light W.
FRIDAY: Mostly sunny. Highs 80-88, coolest coast. Wind light variable with sea breezes.
SATURDAY: Mostly sunny. Lows 60-68, warmest urban areas. Highs 78-88, coolest coast.
SUNDAY: Partly sunny. Lows 60-68, warmest urban areas. Highs 78-88, coolest coast.
MONDAY: Mostly cloudy. Chance of showers/thunderstorms. Humid. Lows 62-70. Highs 77-86.

DAYS 6-10 (AUGUST 23-27)…
High pressure builds in August 23 then hangs around through August 26 with fair weather and temperatures from near normal early in the period to above normal later in the period. A front may approach about August 27 but probably run out of steam and have little impact.

DAYS 11-15 (AUGUST 28-SEPTEMBER 1)…
High pressure will be the dominant feature but centered offshore it will allow more humidity and the risk of a few showers/thunderstorms as weak systems try to approach from the west. A tropical system may be somewhere off the East Coast during this period but far too soon to know its strength or position.

Wednesday Forecast

9:29AM

DAYS 1-5 (AUGUST 17-21)…
Post cold front today, still fairly warm, but humidity drops off as a gusty wind blows and see see a sun/cloud mix, trending sunnier. Another cold front approaches Thursday and we see a brief spike in humidity and heat and a risk of a few afternoon showers/thunderstorms. High pressure builds in with fabulous late summer weather Friday-Sunday with seasonable warmth and some coastal sea breezes this weekend.
TODAY: Partly to mostly sunny. Less humid. Highs 77-82 Cape Cod, 83-88 elsewhere. Wind NW 10-20 MPH and gusty, diminishing late in the day.
TONIGHT: Mostly clear. Lows 58-63 interior valleys, 63-68 elsewhere. Wind light NW to W.
THURSDAY: Sunny to partly cloudy. Isolated afternoon showers/thunderstorms. More humid. Highs 79-84 South Coast, 85-90 elsewhere. Wind W to SW 5-15 MPH.
THURSDAY NIGHT: Partly cloudy. Less humid. Lows 60-68, warmest urban areas. Wind light W.
FRIDAY: Mostly sunny. Highs 80-88, coolest coast. Wind light variable with sea breezes.
SATURDAY: Mostly sunny. Lows 60-68, warmest urban areas. Highs 78-88, coolest coast.
SUNDAY: Partly sunny. Lows 60-68, warmest urban areas. Highs 78-88, coolest coast.

DAYS 6-10 (AUGUST 22-26)…
Slow-moving front brings a chance of showers/thunderstorms August 22-23 with higher humidity. High pressure dominates with fair and seasonably warm weather August 24-26.

DAYS 11-15 (AUGUST 27-31)…
Slightly cooler weather and a risk of a few showers around the August 27-28 weekend, then fair and warm to hot to end the month.

Tuesday Forecast

9:09AM

DAYS 1-5 (AUGUST 16-20)…
A warm front will move into southern New England today, taking its time at first. You’ve heard talk of the threat of severe storms, and I will not downplay that, because there is a threat, but the atmosphere has presented us with a layer of warm and stable air to overcome first, and that may be quite preventative in storm development for several hours. Later, any storms that do form will favor western areas, but they cannot be rule out from migrating eastward later in the day into this evening. Once again, expect more isolated coverage of heavier activity versus a more general outbreak. Will monitor conditions this afternoon and update in the comments section if needed. The most unstable air will be around tonight as we are in the warm sector, with high humidity, and a cold front approaches. This may trigger some nighttime storms until the cold front crosses the region, which it should do by dawn or shortly thereafter on Wednesday, which will turn out to be a breezy day with lowering humidity but absent of an additional rain threat. The next shot at a few showers/storms will be later Thursday with the approach of another front, but this will have limited moisture to work with. High pressure overtakes the region and brings fair weather Friday and Saturday.
TODAY: Variably cloudy. Isolated light showers north and west of Boston this morning. Isolated to scattered showers and thunderstorms this afternoon. Any storms may be strong. Increasingly humid. Highs 77-82 South Coast, 83-88 elsewhere but likely late in the day. Wind SE to S 5-15 MPH, shifting to SW late.
TONIGHT: Partly cloudy. Isolated to scattered thunderstorms. Humid. Lows 64-72, warmest urban areas. Wind SW 5-15 MPH.
WEDNESDAY: Partly sunny. Lowering humidity. Highs 78-86, coolest South Coast. Wind NW 10-20 MPH with higher gusts.
THURSDAY: Partly cloudy. Isolated showers/thunderstorms mainly late-day. Lows 62-70, warmest urban areas. Highs 78-88, coolest South Coast.
FRIDAY: Mostly sunny. Lows 58-66, coolest interior valleys. Highs 78-88, coolest in coastal areas.
SATURDAY: Partly cloudy. Lows 58-66, coolest interior valleys. Highs 78-88, coolest in coastal areas.

DAYS 6-10 (AUGUST 21-25)…
High pressure should hang on for fair weather August 21. Slow-moving but weak front brings more humidity and a risk of showers August 22-23. Fair and drier August 24-25. Temperatures near to above normal.

DAYS 11-15 (AUGUST 26-30)…
Overall pattern looks mainly dry with limited shower/t-storm chances. Temperatures near to above normal.

Monday Forecast

9:40AM

DAYS 1-5 (AUGUST 15-19)…
A little drying at the surface today, and the edge coming off the heat means it will feel a little more comfortable today as a weak area of high pressure drifts over the region, but some mid and high level moisture will not allow it to be a totally sunny day. Humidity comes back as a warm front crosses the region Tuesday. The low pressure area parenting this front will also send its cold front across the area Wednesday. This frontal combo means a risk of a few rounds of showers and thunderstorms, but again not looking for a widespread beneficial rain. I have a slight concern for some stronger storms at least over interior areas later Tuesday, but will re-evaluate this going forward. Another weak area of high pressure moves in Thursday but a second cold front approaches later in the day, and it may help trigger a few showers and thunderstorms, though they will be the exception and not the rule (a phrase used quite often this summer). High pressure returns Friday making it a great summer day.
TODAY: Partly cloudy. Highs 78-85 South Coast, 85-92 elsewhere. Wind W to NW 5-15 MPH, diminishing later and allowing for some coastal sea breezes.
TONIGHT: Partly cloudy. Lows 62-69, warmest in urban areas. Wind light SE.
TUESDAY: Variably cloudy. Episodes of showers. Slight chance of thunderstorms. Humid. Highs 77-82 South Coast, 83-88 elsewhere but likely late in the day. Wind SE to S 5-15 MPH, shifting to SW late.
TUESDAY NIGHT: Partly cloudy. Isolated thunderstorms. Humid. Lows 64-72, warmest urban areas. Wind SW 5-15 MPH.
WEDNESDAY: Variably cloudy. Scattered showers and thunderstorms. Humid. Highs 78-86, coolest South Coast. Wind SW 10-20 MPH with higher gusts, shifting to NW.
THURSDAY: Partly cloudy. Isolated showers/thunderstorms mainly late-day. Lows 62-70, warmest urban areas. Highs 78-88, coolest South Coast.
FRIDAY: Mostly sunny. Lows 58-66, coolest interior valleys. Highs 78-88, coolest Cape Cod.

DAYS 6-10 (AUGUST 20-24)…
High pressure brings great weather for the weekend August 20-21. Slow-moving but weak front brings more humidity and a risk of showers August 22-23. Fair and drier August 24.

DAYS 11-15 (AUGUST 25-29)…
Overall pattern looks dry and warm.

Sunday Forecast

8:25AM

DAYS 1-5 (AUGUST 14-18)…
Back into the heat today but a cold front approaching from the northwest will ignite additional isolated to scattered thunderstorms. Monday-Thursday, the front will be hanging out nearby, probably staying just far enough south for dry weather Monday, sliding northward for a couple days of shower threats Tuesday-Wednesday, then back to the south again for dry weather Thursday.
TODAY: Partly sunny. Isolated to scattered showers and thunderstorms. Humid. Highs 76-82 Nantucket, 82-90 South Coast, 90-97 elsewhere. Wind S to SW 5-15 MPH.
TONIGHT: Variably cloudy. Chance of a shower or thunderstorm early. Humid. Lows 65-74, warmest urban areas. Wind W 5-15 MPH.
MONDAY: Partly cloudy. Humid. Highs 77-83 South Coast, 84-91 elsewhere.
TUESDAY: Variably cloudy. Chance of showers. Humid. Lows 60-70, warmest urban areas. Highs 78-86, coolest South Coast.
WEDNESDAY: Mostly cloudy. Chance of showers and thunderstorms. Humid. Lows 60-68. Highs 76-84, coolest Cape Cod.
THURSDAY: Partly cloudy. Less humid. Lows 60-68. Highs 77-86, coolest Cape Cod.

DAYS 6-10 (AUGUST 19-23)…
High pressure will dominate with fair weather August 19-21. A few showers are possible August 22-23 with more humidity. Temperatures above normal.

DAYS 11-15 (AUGUST 24-28)…
Warm to hot, limited shower/storm chances.

Saturday Forecast

8:39AM

DAYS 1-5 (AUGUST 13-17)…
Your reading assignment was far too long yesterday, so let’s shorten things up today by saying that the overall thought process remains the same: Unsettled weather is the general theme for this period but not a whole lot in the way of widespread rainfall. Still working out some timing issues so the forecast beyond tomorrow is moderate confidence. We’ll be bisected by a front today, as we talked about yesterday, and that will make the weather range widely from northeastern portions of the forecast area to southwestern locations. Still expecting us to get back into the hotter air mass for tomorrow before a front comes back and takes the heat out of the picture for a few days to start the new week. My uncertainty lies in the precipitation chances during the Monday-Wednesday period. Playing the less versus more scenario for now. Updates to come as always.
TODAY: Mostly cloudy southeastern NH through northeastern and east central MA with a risk of a few showers. Elsewhere variably cloudy with scattered showers/thunderstorms, some of which may be strong. Humid. Highs 75-82 coastal NH and eastern MA, 83-92 elsewhere. Wind NE 5-15 MPH over southeastern NH and eastern MA, S to SW 5-15 MPH in areas further west and southwest.
TONIGHT: Mostly cloudy. Patchy fog. Chance of a few showers. Isolated heavier thunderstorms possible central MA to southwestern NH. Humid. Lows 62-72, warmest far west and southwest of Boston. Wind variable up to 10 MPH becoming SE to S in most areas overnight.
SUNDAY: Partly sunny. Isolated to scattered showers and thunderstorms. Humid. Highs 75-80 Nantucket, 80-88 South Coast, 88-95 elsewhere. Wind S to SW 5-15 MPH.
MONDAY: Mostly cloudy. Chance of showers, favoring the morning. Humid. Lows 64-74. Highs 77-85.
TUESDAY: Partly cloudy. Less humid. Lows 60-70, warmest urban areas. Highs 78-86.
WEDNESDAY: Mostly cloudy. Chance of showers. More humid. Lows 60-68. Highs 76-84.

DAYS 6-10 (AUGUST 18-22)…
Speeding timing up with a weak front bringing a risk of showers August 18 then fair weather dominating August 19-21 as high pressure takes over. Warm/muggy and a risk of showers/thunderstorms for August 22.

DAYS 11-15 (AUGUST 23-27)…
Warm to hot, limited shower/storm chances.

Friday Forecast

8:10AM

DAYS 1-5 (AUGUST 12-16)…
Complex forecast as a frontal boundary gets involved in the forecast during the next several days. Its position will make a big difference in local weather. It looks like today the entire southern New England region will still be in the heat, like yesterday, as the front will be to the north, but a little wave of low pressure moving along it, and off the coast of Maine by evening, combined with a little nose of high pressure extending southeastward from eastern Canada, will push this front south southwestward across southern NH and into eastern MA tonight into Saturday. It will come to a stop somewhere in a line from southern MA or northern RI back across east central MA to southwestern NH most likely, hanging there for a good part of Saturday before returning back northeastward across the region by early Sunday. So areas that end up on the other side of the front after it passes will be cooler Saturday, while areas that are not reached by the front will stay rather hot, and then the heat will be in general control over most of the region again by Sunday as the front moves back the other way. But another wave of low pressure moving along the boundary sometimes between Sunday night and the middle of Monday will pull the front southward again, but this time being more orientated in a “traditional” way so that it comes through from northwest to southeast. End result? We should get into a slice of drier air by late Monday or certainly Tuesday. As for showers/thunderstorms during this period, that is a complex puzzle as well. I think the area as a whole will fall short of getting greatly beneficial rain, but some areas will see at least one round of decent showers and thunderstorms. Details will have to be worked out on a day-by-day basis, so I can say that today’s activity will be isolated to scattered, can occur any time, but will favor the afternoon to early evening, when any storms that occur can be strong to severe, so keep an eye out for changing conditions. Saturday’s greatest storm risk will be closer to the South Coast and back through central MA and southwestern NH where the hot/muggy air is, with more cloudiness but less rain risk further north and east. Sunday will carry a risk of isolated to scattered showers/thunderstorms as the region gets back into the hot/muggy air. We’ll have to see if a more organized area of showers/storms occurs at some point Sunday night and/or Monday, depending on the timing of the front as it makes its second southward push. A bubble of high pressure should bring a break in the action by Tuesday, based on current timing. Again please check for updates as timing of location of the front, and resultant showers/storms is hard to pin point. Lastly, for late tonight and early Saturday, which is the second peak period for the Perseid Meteor Shower, we will have to keep an eye on cloudiness that may still be around from afternoon / evening thunderstorms. I think most of it should exit, but then there will be the issue of possible low cloudiness coming down from the north and northeast with the passage of the front during the late evening and overnight hours. So no area is a lock for clear sky, but some areas may end up ok for several hours. Updates will be posted in the comments section as well as on the WHW Facebook page.
TODAY: Mostly sunny to partly cloudy with very isolated showers and a slight risk of thunderstorms through midday. Partly sunny during the afternoon with isolated to scattered showers and thunderstorms. Any storms may be locally strong to severe. Very humid. Highs 75-82 Nantucket, 82-90 South Coast, 90-97 elsewhere. Wind SW 5-15 MPH with higher gusts.
TONIGHT: Variably cloudy with a risk of showers/thunderstorms early evening. Partly cloudy to mostly clear late evening. Overnight, possible deck of low clouds at least coastal NH and eastern MA but may spread inland somewhat by dawn. Patchy fog. Very humid. Lows 62-70 in areas that saw rain late-day and evening as well as coastal NH and northeastern MA, 70-77 urban areas and any areas in southern MA, RI, and interior NH that did not see late-day rain.
SATURDAY: Mostly cloudy southeastern NH through northeastern and east central MA with a risk of a few showers. Elsewhere variably cloudy with scattered showers/thunderstorms, some of which may be strong. Humid. Highs 75-82 coastal NH and eastern MA, 83-92 elsewhere. Wind NE 5-15 MPH over southeastern NH and eastern MA, S to SW 5-15 MPH in areas further west and southwest.
SATURDAY NIGHT: Mostly cloudy. Patchy fog. Chance of a few showers. Isolated heavier thunderstorms possible central MA to southwestern NH. Humid. Lows 62-72, warmest far west and southwest of Boston. Wind variable up to 10 MPH becoming SE to S in most areas overnight.
SUNDAY: Partly sunny. Isolated to scattered showers and thunderstorms. Humid. Highs 75-80 Nantucket, 80-88 South Coast, 88-95 elsewhere. Wind S to SW 5-15 MPH.
MONDAY: Mostly cloudy. Chance of showers, favoring the morning. Humid. Lows 64-74. Highs 77-85.
TUESDAY: Partly cloudy. Less humid. Lows 60-70, warmest urban areas. Highs 78-86.

DAYS 6-10 (AUGUST 17-21)…
More humid with showers possible August 17. Next shower risk late August 19 to early August 20. Drier at the end of the period. Temperatures near to above normal.

DAYS 11-15 (AUGUST 22-26)…
Still looking for another build of heat/humidity with few chances for showers/storms.

Thursday Forecast

7:27AM

DAYS 1-5 (AUGUST 11-15)…
High pressure aloft brings the heat and humidity for the next few days, at least through Saturday, to southern New England. Thunderstorm chances will be limited as a frontal system will stay pretty far to the north for the next 3 days and storm triggers would really just be air mass heat and humidity. Also, it being fairly warm aloft sometimes limits the lifetime of single storms, making it more difficult for them to form clusters or lines and stay more organized or last longer. Regardless, though coverage of storms will be very low, any location that does see a storm could experience torrential rain, lightning, and gusty wind, so watch for any pop up storms if you will be outside, and even more importantly, try to avoid over exertion in the hot, humid conditions. Stay hydrated and out of the sun whenever possible. A front is expected to eventually slip southward and may trigger a few more showers and thunderstorms at some point on Sunday, but as of now I have my doubts about this activity being widespread or long lasting. Our best shot at a widespread area of rain may come during the morning hours of Monday as a low pressure wave moves along the front just after it settles to the south. A REMINDER! The Perseid Meteor Shower peaks during the next 2 late nights / early mornings (tonight / Friday early AM, Friday night / Saturday early AM). Best viewing is accomplished by removing yourself from light pollution to as dark an area as possible, and looking high in the northeastern sky toward the constellation Persius between midnight and first light. There may be some haze present, and a few areas may have patchy fog, but with luck the sky should be generally clear otherwise on both nights though I’m more confident in tonight.
TODAY: Mostly sunny. Remote risk of a few showers and thunderstorms in CT and RI, and possibly extreme southern MA, through early afternoon. Humid. Highs 82-88 Cape Cod and immediate South Coast, 89-98 elsewhere. Wind light S to SW.
TONIGHT: Mostly clear. Patchy ground fog. Humid. Lows 68-79, warmest in urban areas. Wind light SW.
FRIDAY: Partly cloudy. Isolated showers and thunderstorms. Humid. Highs 82-88 South Coast, 88-96 elsewhere. Wind light SW.
FRIDAY NIGHT: Partly cloudy. Patchy fog. Humid. Lows 67-78, warmest urban areas. Wind light SW.
SATURDAY: Partly cloudy. Isolated showers and thunderstorms. Humid. Highs 80-88 South Coast, 88-96 elsewhere. Wind SW 5-15 MPH.
SUNDAY: Variably cloudy. Isolated to scattered showers and thunderstorms. Humid. Lows 66-77, warmest urban areas. Highs 80-92, coolest Cape Cod.
MONDAY: Mostly cloudy. Chance of showers, favoring the morning. Humid. Lows 64-74. Highs 77-84.

DAYS 6-10 (AUGUST 16-20)…
Some mid period humidity and a possible shower/thunderstorm risk between fair and somewhat drier weather to start and end the period.

DAYS 11-15 (AUGUST 21-25)…
A re-building of heat and humidity this period, but timing of any accompanying showers and thunderstorms is uncertain. Likely very limited rainfall.

Wednesday Forecast

9:01AM

DAYS 1-5 (AUGUST 10-14)…
A disturbance passing through the region this morning and early afternoon is the gateway to higher humidity, which will last for several days, through and probably beyond this 5-day period, and some heat as well, especially Thursday through Saturday. Rain chances will be limited, with today being the greatest chance overall in terms of coverage, as the disturbance moves through. But even as it does so, on the larger scale it will be weakening. As humidity comes up, during and after the passage of the disturbance, isolated heavier showers and thunderstorms may pop up, but expect coverage of heavier rain to be fairly isolated. A few of these may linger into this evening but again in very isolated areas. As the heat takes over tomorrow, it will likely be stable enough, despite the humidity, to limit or eliminate storm chances, but the risk should return Friday in a limited fashion, and perhaps a little more on Saturday as a front from the north gets closer. The position of this front is uncertain a few days out, but it looks like it should slip southward by early Sunday and knock the heat down several notches but allowing the humidity to remain fairly high. I’m not nearly sold on a widespread rain for Sunday, but other than today, that day carries the highest rain risk.
TODAY: Mostly cloudy through midday with a couple areas of rain and showers. Embedded thunder possible in isolated heavier rain areas. Partly sunny mid afternoon on with isolated showers and thunderstorms. Any storms could be briefly strong but in localized areas. later Increasingly humid. Highs 78-86. Wind S to SW 5-15 MPH.
TONIGHT: Partly cloudy with a slight risk of an isolated shower or thunderstorm early, then mostly clear. Humid. Lows 62-67 except 67-72 urban areas. Wind SW under 10 MPH.
THURSDAY: Mostly sunny. Humid. Highs 82-88 Cape Cod and immediate South Coast, 89-97 elsewhere. Wind SW 5-15 MPH.
THURSDAY NIGHT: Mostly clear. Humid. Lows 66-77, warmest in urban areas. Wind light SW.
FRIDAY: Partly cloudy. Isolated showers and thunderstorms. Humid. Highs 82-88 South Coast, 88-96 elsewhere.
SATURDAY: Partly cloudy. Isolated showers and thunderstorms. Humid. Lows 66-77, warmest urban areas. Highs 80-94, coolest Cape Cod.
SUNDAY: Variably cloudy. Isolated to scattered showers and thunderstorms. Humid. Lows 66-77, warmest urban areas. Highs 80-92, coolest Cape Cod.

DAYS 6-10 (AUGUST 15-19)…
Rain risk early August 15 then drying trend with fair weather returning through August 17 before humidity returns later in the period with a risk of isolated thunderstorms.

DAYS 11-15 (AUGUST 20-24)…
Fair, cooler, less humid early in the period. Heat and humidity likely return again later in the period.

Tuesday Forecast

8:28AM

DAYS 1-5 (AUGUST 9-13)…
One more day of low humidity and lots of sun, though some clouds arrive later in the day as the first signs of increasing warmth and moisture aloft arrive. This portends a change in the weather, and we’ll feel it in the form of several days of increased humidity, more heat, and some opportunities for showers and thunderstorms, however these will be limited, at least initially. The first shot at unsettled weather comes fairly early Wednesday as the humid air makes its arrival and a disturbance rapidly crosses the region. This may bring an area of at least light rain but possibly some embedded heavier from west to east during the mid morning to early afternoon Wednesday. Later in the day rain will be hard to find and while a few isolated showers and thunderstorms may pop up, odds favor them being far west and north of much of southern New England and probably weakening before they’d have any chance to travel into the region. At this point, Thursday looks shower/thunderstorm-free, with only isolated to scattered activity expected Friday and Saturday. Although any storms that could potential form late in the week could be quite heavy, expect this once again to be the exception rather than the rule.
TODAY: Mostly sunny through early afternoon then partly cloudy mid afternoon on. Highs 79-85 coast, 86-91 interior. Wind light variable with coastal sea breezes.
TONIGHT: Variably cloudy. Lows 60-65 except 65-70 urban areas. Wind light S.
WEDNESDAY: Mostly cloudy through midday with a couple areas of rain or showers. Partly cloudy later in the day. Increasingly humid. Highs 78-84 South Coast, 85-91 elsewhere. Wind S to SW 5-15 MPH.
WEDNESDAY NIGHT: Partly cloudy with a slight risk of an isolated shower or thunderstorm early, then mostly clear. Humid. Lows 62-67 except 67-72 urban areas. Wind SW under 10 MPH.
THURSDAY: Mostly sunny. Humid. Highs 80-88 coastal areas, 88-96 interior. Wind SW to S 5-15 MPH.
FRIDAY: Partly cloudy. Isolated showers and thunderstorms. Humid. Lows 64-74, warmest urban areas. Highs 80-86 coast, 87-94 interior.
SATURDAY: Partly sunny. Scattered showers and thunderstorms. Humid. Lows 64-74, warmest urban areas. Highs 80-92, coolest Cape Cod.

DAYS 6-10 (AUGUST 14-18)…
Humid with a shower/thunderstorm risk August 14. Drying trend August 15-16 with fair weather. Fair, warm, increasingly humid August 17-18.

DAYS 11-15 (AUGUST 19-23)…
Shower/thunderstorm risk may come early in the period breaking the humidity with a cooler/drier mid period before heat and humidity returns later in the period.

Monday Forecast

9:25AM

DAYS 1-5 (AUGUST 8-12)…
High pressure dominates today and Tuesday with plenty of sunshine along with warm and dry air. A frontal system will arrive Wednesday with more cloudiness, humidity, and the risk of showers and thunderstorms. Will watch the potential for some strong storms, but at this point my feeling is that once again this will be the major exception, and that coverage of evening general shower and thunderstorm activity will be low. A brief break Thursday with slightly drier but hotter weather will be followed by another risk of scattered showers and thunderstorms and humid conditions on Friday.
TODAY: Mostly sunny. Highs 80-88, coolest Cape Cod. Wind NW 5-15 MPH.
TONIGHT: Mostly clear. Lows 60-68, coolest interior valleys. Wind light N.
TUESDAY: Mostly sunny. Highs 82-90, coolest coastal areas. Wind light variable with light sea breeze in coastal areas.
WEDNESDAY: Variably cloudy. Isolated to scattered showers/thunderstorms. Humid. Lows 62-70. Highs 78-88, coolest South Coast.
THURSDAY: Partly sunny. Less humid. Lows 62-70. Highs 78-85 South Coast, 86-93 elsewhere.
FRIDAY: Variably cloudy. Scattered showers/thunderstorms. More humid. Lows 62-70. Highs 78-88, coolest South Coast.

DAYS 6-10 (AUGUST 13-17)…
Humid weather and a daily risk of isolated to scattered showers and thunderstorms during the weekend of August 13-14. Trending drier August 15-17. Temperatures near to above normal.

DAYS 11-15 (AUGUST 18-22)…
Cooler weather possible for a few days early to mid period, then building heat and humidity may return with the emergence of the Bermuda High later in the period.

Sunday Forecast

8:12AM

DAYS 1-5 (AUGUST 7-11)…
High pressure retakes the weather today but a weak disturbance passing through from northwest to southeast later in the day will bring some cloudiness including the remote risk of a passing shower in southeastern NH and/or northeastern MA. Sun will dominate Monday and Tuesday with dry air. Humidity creeps up Wednesday and that day may feature a few showers and thunderstorms from an approaching cold front, which will slip south of the region by Thursday when we go right back to dry conditions (or stay there in areas that miss Wednesday showers).
TODAY: Sunshine dominates through early afternoon then some cloudiness arrives especially southern NH and eastern MA with a remote risk of a passing shower before sunset in southeastern NH and northeastern MA. Highs 80-88. Wind NW 5-15 MPH with higher gusts.
TONIGHT: Partly cloudy. Lows 60-68. Wind light NW to N.
MONDAY: Mostly sunny. Highs 78-86. Wind N 5-15 MPH.
TUESDAY: Mostly sunny. Lows 58-67, coolest interior valleys and warmest urban areas. Highs 80-88, coolest coast.
WEDNESDAY: Partly cloudy. Isolated showers and thunderstorms late day. More humid. Lows 60-68. Highs 82-90, coolest coast.
THURSDAY: Mostly sunny. Lows 60-68. Highs 82-90, coolest coast.

DAYS 6-10 (AUGUST 12-16)…
A front in the area August 12-14 brings more humidity and the risk of a few showers and thunderstorms, though it does not look like any widespread rain. Fair and less humid August 15-16. Temperatures near to above normal.

DAYS 11-15 (AUGUST 17-21)…
Continued lower confidence forecast – still looking fairly dry with a possible cooling trend.

Saturday Forecast

9:32AM

DAYS 1-5 (AUGUST 6-10)…
Today’s storm threat: We have a pre-frontal trough, which in layman’s terms is a line of lower pressure and lift, like a front, moving slowly south southeastward into MA from northern New England, which carries some showers on it as of mid morning. These will fade with time and this line, as it continues to drop southward through MA toward CT and RI, will be the focal point for new showers and thunderstorms by the middle of the day and certainly the first half of the afternoon. The cloudiness with the initial showers may limit development north of the Mass Pike as this trough moves through that region, especially since there hasn’t been much, if any, sunshine to heat the lower atmosphere and destabilize it. The storms that do fire up in southern MA and moving into CT and RI may be quite strong, and locally severe. I still believe this will be the exception rather than the rule even in that region, and that the worst of the weather will be confined to rather isolated locations. But since it is a summer weekend, if you are in this area pay very close attention to changing weather today. But what about the actual cold front? Yes that still has to come through as well and will be moving along later this afternoon and early evening, but will only have the ability to initiate isolated to scattered storms. The best support for this may stay up across Maine but still cannot rule out an isolated shower or storm anywhere else as this front passes. By dusk, all activity will have dissipated or moved away. After the bit of action around today, we go back into the quiet pattern of dominant high pressure Sunday into the middle of next week.
TODAY: Variably cloudy. Scattered showers mid to late morning from southern NH and northern MA into east central MA with a remote risk of an isolated heavier thunderstorm in eastern MA. Redeveloping showers/thunderstorms most likely in a broken line near the Mass Pike then moving southeastward through southern MA, CT, and RI during the early to mid afternoon hours. Any storms may be strong to locally severe. Elsewhere just an additional isolated shower or thunderstorm possible through early evening. Humid. Highs 78-85 coast, coolest Cape Cod, and 86-92 elsewhere, warmest Merrimack Valley and southwestern NH. Wind SW 10-20 MPH with higher gusts.
TONIGHT: Partly cloudy early, then mostly clear. Less humid. Lows 62-70, warmest in urban areas. Wind W to NW 5-15 MPH.
SUNDAY: Mostly sunny, except some cloudiness in southern NH and eastern MA late day. Highs 80-88. Wind NW 5-15 MPH with higher gusts.
SUNDAY NIGHT: Partly cloudy. Lows 60-68. Wind light NW to N.
MONDAY: Mostly sunny. Highs 78-86. Wind N 5-15 MPH.
TUESDAY: Mostly sunny. Lows 58-67, coolest interior valleys and warmest urban areas. Highs 80-88, coolest coast.
WEDNESDAY: Mostly sunny. Lows 60-68. Highs 82-90, coolest coast.

DAYS 6-10 (AUGUST 11-15)…
Current timing brings a weak front through the region August 11 with only a remote shower/thunderstorm risk then another stretch of fair weather is expected with temperatures generally near to above normal. Perseid Meteor Shower occurs early to mid period so will be keeping an eye on sky conditions for late-night viewing.

DAYS 11-15 (AUGUST 16-20)…
Lower confidence forecast at this point but still looks fairly dry though temperatures may temporarily trend cooler.
