Sunday Forecast

7:26AM

DAYS 1-5 (SEPTEMBER 30-OCTOBER 4)
High pressure remains in control on this final day of September with very nice weather for your Sunday, and then the opening days of October will feature several changes as a frontal boundary wavers back and forth nearby. We will see the front lift north of the region putting us onto the warmer side during Monday into Tuesday, then see it sink southward putting the region on the cooler side Wednesday only to have it go back the other day for the return of the warmer side of things by Thursday. Some unsettled weather will accompany changes. Forecast details…
TODAY: Mostly sunny. Highs 63-70. Wind light variable.
TONIGHT: Variably cloudy. Lows 46-53. Wind light variable.
MONDAY: Partly sunny to mostly cloudy. Chance of a shower. Highs 67-74. Wind S 5-15 MPH.
MONDAY NIGHT: Mostly cloudy. Chance of a few showers. Lows 52-58. Wind SW 5-15 MPH.
TUESDAY: Variably cloudy. Possible showers. Highs 70-77. Wind SW 5-15 MPH.
WEDNESDAY: Partly cloudy. Showers possible early. Lows in the 50s. Highs from the middle to upper 60s.
THURSDAY: Partly sunny. Showers possible early. Lows from the upper 50s to lower 60s. Highs in the 70s.

DAYS 6-10 (OCTOBER 5-9)
Frontal boundary wavers around the region while high pressure aloft dominates for the first few days of the period with a few shower episodes possible and overall mild weather. High pressure controls surface and aloft with dry weather and above normal temperatures later in the period.

DAYS 11-15 (OCTOBER 10-14)
Expecting the dominant ridge to weaken and retreat southward allowing a more west to east, stronger jet stream flow, some periodic shower episodes and temperature changes during this period.

Saturday Forecast

8:37AM

DAYS 1-5 (SEPTEMBER 29-OCTOBER 3)
High pressure dominates the weather this weekend. A weak boundary sneaks by tonight and divides a mild day today from a slightly cooler tomorrow, but the difference will not be very drastic. That boundary scoots back to the north allowing a warm-up as October gets underway, then comes back to the south to produce a round of showers Tuesday night and bringing slightly cooler air as it dries out again Wednesday. Forecast details…
TODAY: Areas of fog and low clouds southern MA, RI, and eastern CT through mid morning, otherwise mostly sunny. Highs 68-75. Wind NW 5-15 MPH.
TONIGHT: Partly cloudy. Lows 43-52, mildest immediate coast and urban areas Wind light W shifting to N.
SUNDAY: Mostly sunny. Highs 63-70. Wind light variable.
SUNDAY NIGHT: Variably cloudy. Lows 46-53. Wind light variable.
MONDAY: Partly sunny. Highs 67-74. Wind SW 5-15 MPH.
TUESDAY: Partly cloudy. Showers likely at night. Lows in the 50s. Highs in the 70s.
WEDNESDAY: Partly sunny. Showers possible early. Lows in the 50s. Highs from the middle to upper 60s.

DAYS 6-10 (OCTOBER 4-8)
Looking more and more like high pressure will be stronger along the East Coast during this period. At the surface, we’ll be back in the warm sector October 4 then on the other side of a front, the “cooler” side, which won’t really be much cooler, October 5, only to go back to the warm side of it for a couple days before reversing itself yet again, but with all this wavering of an air mass boundary, it looks like a fairly dry pattern with the high pressure aloft in control.

DAYS 11-15 (OCTOBER 9-13)
Since the 6-10 day period did not present itself the way it now looks, there is pretty much a low confidence lock on this period, but the early guess is a weakening of high pressure and a more west to east flow and a trend toward somewhat more seasonable though changeable weather.

Friday Forecast

7:30AM

DAYS 1-5 (SEPTEMBER 28-OCTOBER 2)
This would have been that snowstorm with short notice in the winter. A few days ago I worried about a wave of low pressure bringing wet weather for part of Friday, then backed off on the rain risk and held on to the clouds, only to realize the low pressure wave was going to produce at least some rain, prompting me to re-introduce it to the forecast, and now today, if only briefly, some areas will see heavy rain as this wave passes by, but it’s gone tonight, and we have a spectacular weekend ahead, mildest day Saturday and a little cooler Sunday, as a weak boundary will have passed by virtually unnoticed Saturday night. When we get to the start of next week, and the start of a new month, high pressure will settled to the south, a warm front passes Monday with no more than some cloudiness, and a mild push of air will be with us into much of Tuesday before a cold front brings a shower risk by the end of the day. Forecast details…
TODAY: Overcast. Rain likely this morning, heaviest southeastern MA and RI. Rain tapering off southwest to northeast during the afternoon. Highs 54-60 Boston-Providence northwestward, 61-68 to the southeast. Wind NE 5-10 MPH Boston-Providence areas northwestward, SE-S 5-15 MPH in areas to the southeast.
TONIGHT: Mostly cloudy with patchy fog evening. Gradual clearing but still patchy ground fog overnight. Lows 48-55. Wind light N to NW.
SATURDAY: Mostly sunny. Highs 68-75. Wind NW to W 5-15 MPH.
SATURDAY NIGHT: Partly cloudy. Lows 43-52, mildest immediate coast and urban areas Wind light W shifting to N.
SUNDAY: Mostly sunny. Highs 63-70. Wind light variable.
MONDAY: Partly sunny. Lows from the upper 40s to middle 50s. Highs from the upper 60s to middle 70s.
TUESDAY: Partly cloudy. Late-day and nighttime showers possible. Lows in the 50s. Highs in the 70s.

DAYS 6-10 (OCTOBER 3-7)
Fair, slightly cooler October 3. Fair, warm October 4 but nighttime showers. Fair and a cooling trend October 5-7.

DAYS 11-15 (OCTOBER 8-12)
Fair weather starts the period, then unsettled weather followed by a warm-up as weather systems continue to progress.

Thursday Forecast

7:26AM

DAYS 1-5 (SEPTEMBER 27-OCTOBER 1)
Drying out today as a small area of high pressure moves in. The front that went by last night with thunderstorms sits just offshore, however, and a wave of low pressure will ripple up along it Friday bringing cloudiness back and a threat of a couple periods of light rain. But the timing looks good for a great weekend with only a cold front passing by Saturday night with no precipitation associated with it, dividing a mild Saturday from a cooler Sunday. A warm front will pass by Monday bringing milder air for the start of the new month.
Forecast details…
TODAY: Increasing sun. Less humid. Highs 65-72. Wind N 5-15 MPH becoming NE.
THURSDAY NIGHT: Increasing clouds. Lows 52-58. Wind NE 5-15 MPH.
FRIDAY: Mostly cloudy. A couple periods of light rain possible. Highs 61-67. Wind NE 5-15 MPH becoming N.
FRIDAY NIGHT: Slow clearing. Lows 46-53. Wind light N becoming W.
SATURDAY: Mostly sunny to partly cloudy. Highs 66-73. Wind W to SW 5-15 MPH.
SUNDAY: Partly cloudy to mostly sunny. Lows from the upper 40s to middle 50s. Highs in the 60s.
MONDAY: Partly sunny. Lows from the upper 40s to middle 50s. Highs from the middle 60s to lower 70s.

DAYS 6-10 (OCTOBER 2-6)
A boundary will be back and forth over the region and we should be on the warm side October 2 and 4, the cooler side the other days. The greatest threat of wet weather during transitions is late October 2 and early October 5.

DAYS 11-15 (OCTOBER 7-11)
A cool start, then milder, a shower threat following and then a return to cooler at the end of the period.

Wednesday Forecast

7:18AM

DAYS 1-5 (SEPTEMBER 26-30)
This area will be in a wedge of tropical air today behind the warm front that brought yesterday’s rain and ahead of a cold front that will bring a shower or thunderstorm to some areas tonight. During the day today a few downpours are possible, but favoring the morning hours and areas from RI through eastern MA. Not everybody sees one but if you do, the rain could be torrential for a short time. All of this gets pushed out of here by that cold front, setting up a nicer Thursday, though not 100% sunny. And those clouds increase again Thursday night into Friday as a disturbance slides up along the front just offshore. Still thinking the rain doesn’t quite materialize with this but I’m not 100% confident of that at this point. The front I spoke of on yesterday’s forecast timed for next Sunday actually looks faster and weaker to me and should come through as a virtually unnoticed entity Saturday night, so the weekend at this point looks quite nice. Forecast details…
TODAY: Mostly to partly cloudy. Scattered showers and possible thunderstorms favoring southeastern MA and RI this morning, otherwise only isolated showers. Humid. Highs 74-82. Wind SW 10-20 MPH.
TONIGHT: Mostly cloudy through evening with a broken to scattered line of showers and possible thunderstorms from west to east. Becoming partly cloudy overnight. Patchy fog. Humid evening, less humid overnight. Lows 58-64. Wind SW 5-15 MPH shifting to NW.
THURSDAY: Partly sunny. Less humid. Highs 65-72. Wind N 5-15 MPH becoming NE.
THURSDAY NIGHT: Mostly cloudy. Lows 52-58. Wind NE 5-15 MPH.
FRIDAY: Variably cloudy. Highs 62-68. Wind NE 5-15 MPH becoming N.
SATURDAY: Mostly sunny to partly cloudy. Lows from the middle 40s to lower 50s. Highs from the middle 60s to lower 70s.
SUNDAY: Partly cloudy to mostly sunny. Lows from the upper 40s to middle 50s. Highs in the 60s.

DAYS 6-10 (OCTOBER 1-5)
Current thoughts are similar to yesterday’s with a warm-up October 1, cold front with shower threat and brief cool down October 2 into October 3 then another warm-up following that, probably with more unsettled weather at the end of the period as another cold front approaches. Timing on all this is low confidence. Fine tuning ahead.

DAYS 11-15 (OCTOBER 6-10)
This period is likely to feature mainly dry but cooler weather before it turns unsettled at the end.

Tuesday Forecast

7:40AM

DAYS 1-5 (SEPTEMBER 25-29)
Warm front approaches today sending a batch of rain into the region, which may end as showers and thunderstorms as the warm air arrives. Low pressure to the south will send a finger of tropical moisture northward and may result in a batch of showers/storms Wednesday morning favoring southeastern areas before we break out some in the warm sector ahead of a cold front, which arrives too late here to bring really strong storms to the region but will nevertheless produce showers and a few possible thunderstorms west to east Wednesday evening. High pressure brings drier and slightly cooler air by Thursday. A wave of low pressure passing southeast of the region Friday will probably toss some cloudiness into the region for a time but at this point I am going to back off on the rain forecast and keep it rain free, with the expectation that the main area of moisture will remain offshore. High pressure regains complete control for a spectacular Saturday. Forecast details…
TODAY: Overcast. Rain arriving southwest to northeast during the morning and continuing through the afternoon. Increasingly humid. Highs 62-68 occurring late in the day. Wind SE 5-15 MPH.
TONIGHT: Mostly cloudy. Areas of fog. Showers likely including a chance of thunderstorms early, then isolated showers overnight. Humid. Temperatures steady 62-68. Wind SW 5-15 MPH.
WEDNESDAY: Mostly to partly cloudy. Scattered showers and thunderstorms favoring southeastern MA and RI early to mid morning, otherwise only isolated showers. Humid. Highs 74-82. Wind SW 10-20 MPH.
WEDNESDAY NIGHT: Mostly cloudy through evening with a broken to scattered line of showers and possible thunderstorms from west to east. Becoming partly cloudy overnight. Patchy fog. Humid evening, less humid overnight. Lows 58-64. Wind SW 5-15 MPH shifting to NW.
THURSDAY: Sun and passing clouds. Less humid. Highs 65-72. Wind N 5-15 MPH.
FRIDAY: Variably cloudy. Lows from the middle to upper 50s. Highs from the middle to upper 60s.
SATURDAY: Mostly sunny. Lows from the middle 40s to lower 50s. Highs from the middle 60s to lower 70s.

DAYS 6-10 (SEPTEMBER 30-OCTOBER 4)
An weakening frontal boundary may bring clouds and perhaps a few showers September 30 but overall still looks like a mainly dry day. A
warm front expected to pass by October 1 with showers followed by a warm-up. Cold front is expected to bring a shower risk October 2, followed by a cool-down. High pressure moves in with fair and cool weather October 3 then moves offshore with a warm-up October 4.

DAYS 11-15 (OCTOBER 5-9)
Front moves through early period with wet weather followed by drier and cooler weather mid period then a late period warm-up.

Monday Forecast

7:20AM

DAYS 1-5 (SEPTEMBER 24-28)
Several changes will take place during the course of this week, which starts out rather chilly as high pressure to the north pushes a northeasterly air flow across the region today. As warm and humid air begins a push into the region from the southwest, it will lead to a rather wet day on Tuesday, pretty much a rainy day from mid morning on, and add in a chance of downpours and maybe even some thunder by evening as more unstable air arrives. Then we get into a warm sector between a warm front and cold front later Tuesday night through the day on Wednesday, with the level of warmth Wednesday determined by how much sun breaks out. One thing that is certain, fairly high humidity, and when the cold front from the west moves into this, it will trigger showers and thunderstorms, some of which could end up on the strong side. The timing of the front may be slow enough so that the threat for stronger storms is generally well west and northwest of Boston and whatever does develop would be in a weaker form once it reaches areas to the south and east – something to keep an eye on. Regardless, high pressure builds in Thursday, a less humid but still mild day. A wave of low pressure may bring a bit of wet weather for part of Friday before drier air returns again. Forecast details…
TODAY: Mostly cloudy to partly sunny with some low clouds off the ocean through midday, then any sunshine starting to fade behind increasing high cloudiness later in the day. Highs 57-64. Wind NE 10-20 MPH, a few higher gusts.
TONIGHT: Thickening overcast. Lows 48-55. Wind E 5-15 MPH.
TUESDAY: Overcast. Rain arriving southwest to northeast during the morning and continuing through the afternoon. Increasingly humid. Highs 62-68 occurring late in the day. Wind SE 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Areas of fog. Showers likely including a chance of thunderstorms early, then isolated showers overnight. Humid. Temperatures steady 62-68. Wind SW 5-15 MPH.
WEDNESDAY: Mostly to partly cloudy. Isolated showers early. Chance of showers/thunderstorms mainly west and north of Boston by late day. Showers likely with a chance of thunderstorms evening. Humid. Highs 74-82. Wind SW 10-20 MPH.
THURSDAY: Partly cloudy. Less humid. Lows from the upper 50s to lower 60s. Highs from the middle 60s to lower 70s.
FRIDAY: Mostly cloudy with a period of rain possible, then partly cloudy. Lows from the middle to upper 50s. Highs from the middle to upper 60s.

DAYS 6-10 (SEPTEMBER 29-OCTOBER 3)
High pressure is expected to bring generally fair weather during the September 29-30 weekend but a frontal boundary dropping down from the north between 2 centers of high pressure may bring some clouds and a shower risk sometime September 30 if enough moisture is available. Warm front expected to pass by October 1 with showers followed by a warm-up. Cold front is expected to bring a shower risk October 2, followed by a cool-down. A bubble of high pressure should bring fair weather for the end of the period.

DAYS 11-15 (OCTOBER 4-8)
Wet weather threat early in the period then mainly fair and cooler weather for the balance of the period as Canadian high pressure moves in.

Sunday Forecast

8:15AM

DAYS 1-5 (SEPTEMBER 23-27)
As autumn gets underway we’ll feel it as some cool air has settled into the region and will be reinforced even further for Monday. But more changes are on the way as the warm and humid air which had been pushed to the south makes a comeback Tuesday and Wednesday, first giving a batch of rain during Tuesday as a warm front move through, then showers and possible thunderstorms Wednesday when we’re in the warmest sector of the air mass and still ahead of an approaching cold front. This front will slog its way through the region by early Thursday which may start wet then dry out somewhat. Forecast details…
TODAY: Cloudiest South Coast, more sun north but still limited at times. Highs 63-69. Wind NW up to 10 MPH.
TONIGHT: Partly cloudy. Lows 43-50. Wind N 5-15 MPH.
MONDAY: Mostly sunny. Highs 57-64. Wind NE 10-20 MPH, a few gusts up to 25 MPH possible.
MONDAY NIGHT: Increasing clouds. Lows 48-55. E to SE 5-15 MPH.
TUESDAY: Cloudy. Rain midday and afternoon. Highs 60-68. Wind SE 5-15 MPH, higher gusts.
WEDNESDAY: Variably cloudy. Showers likely. Chance of thunderstorms. Lows from the upper 50s to lower 60s. Highs from the upper 60s to middle 70s.
THURSDAY: Partly sunny. Chance of showers early. Lows from the lower to middle 60s. Highs from the upper 60s to middle 70s.

DAYS 6-10 (SEPTEMBER 28-OCTOBER 2)
Another disturbance may bring a few showers or a period of rain September 28 before dry and pleasant weather arrives for the September 29-30 weekend to end the month, however it may start mild and end quite cool. Look for a quick warm-up and mainly fair weather to start October, but a shower threat may arrive by October 2 as another front approaches.

DAYS 11-15 (OCTOBER 3-7)
Looking for a wet weather threat possibly lingering early in the period followed by a transition to drier and cooler weather.

Saturday Forecast

2:03AM

DAYS 1-5 (SEPTEMBER 22-26)
The official end of summer and beginning of fall occurs with the Autumnal Equinox tonight at 9:54PM Eastern Daylight Time…
The weather pattern we are in keeps things on the move and changes frequent but not drastic. As a cold front exits the region via the South Coast this morning, we’ll feel comfortable air flowing into the region today and continuing through Sunday, but with the front not that far away, there is going to be a fair amount of high cloudiness across the region at times during the course of the weekend. They won’t produce any rainfall, but they will prevent bright sunshine for the better part of both weekend days. A secondary cold front will move north to south across the region in the early hours of Monday, making it a bit chilly for a brief time, one day only, but the warmth and humidity will begin to make a comeback as a warm front approaches Tuesday, passes by late Tuesday or early Wednesday, and a cold front approaches later Wednesday. This will also result an a return to a wet weather threat during this time. Forecast details…
TODAY: Variably cloudy – limited sun. Highs 66-72. Wind NW 10-20 MPH with higher gusts in the morning, diminishing in the afternoon.
TONIGHT: Variably cloudy. Lows 45-50 except 50-55 immediate shore and urban centers. Wind N up to 10 MPH.
SUNDAY: Variably cloudy – limited sun. Highs 63-69. Wind NW up to 10 MPH.
SUNDAY NIGHT: Partly cloudy. Lows 43-50. Wind N 5-15 MPH.
MONDAY: Mostly sunny. Highs 57-64. Wind NE 10-20 MPH.
TUESDAY: Clouding over. Showers arriving. Lows from the lower to middle 50s. Highs from the middle 60s to lower 70s.
WEDNESDAY: Variably cloudy. Chance of showers. Lows from the upper 50s to lower 60s. Highs from the upper 60s to middle 70s.

DAYS 6-10 (SEPTEMBER 27-OCTOBER 1)
Unsettled weather is expected September into early September 28 before drier weather for the remainder of the period. Temperatures start out mild then cool down mid period followed by a quick warm-up as the calendar changes.

DAYS 11-15 (OCTOBER 2-6)
A little lower confidence on this period but looking for a couple fronts to come through early in the period with showery weather then a drying and cooling trend following this.

Friday Forecast

7:40AM

DAYS 1-5 (SEPTEMBER 21-25)
A warm front passes today bringing a brief spike in humidity and a shot of warmth in that will actually peak tonight ahead of a cold front, and then that cold front will return cooler and drier air to the region during the weekend. The timing of this front means that the squall line of thunderstorms that forms on it well northwest of the region will weaken considerably to just a broken to scattered line of showers by the time it passes by in the early morning hours of Saturday. A second front will come through early Monday with no precipitation but will reinforce the cool air, and by Tuesday the warm air will try to make another come-back so we’ll be returning to clouds and eventually another wet weather threat. Forecast details…
TODAY: Mostly cloudy morning. Partly cloudy afternoon. Highs 73-79. Wind light SE becoming SW and increasing to 10-20 MPH.
TONIGHT: Variably cloudy. Overnight showers and possibly a thunderstorm. Lows 62-68. Wind SW 15-25 MPH, gusts 30-40 MPH possible.
SATURDAY: Risk of a shower early otherwise sun and passing clouds. Highs 68-75. Wind NW 10-20 MPH early, gradually diminishing.
SATURDAY NIGHT: Mostly clear. Lows 52-58. Wind NW 5-15 MPH.
SUNDAY: Mostly sunny. Highs 65-72. Wind NW 5-15 MPH.
MONDAY: Partly sunny. Lows from the middle 40s to lower 50s. Highs from the lower to middle 60s.
TUESDAY: Increasing clouds. Chance of rain late. Lows from the upper 40s to middle 50s. Highs in the 60s.

DAYS 6-10 (SEPTEMBER 26-30)
Spike of warmth but also a shower threat as a warm front / cold front combo passes September 26. A break with fair weather September 27. Another front with a shower risk September 28. Early call is for fair weather for the September 29-30 weekend.

DAYS 11-15 (OCTOBER 1-5)
Watching for a shot of very cool air to start the new month, but may be short-lived followed by a quick warm-up.
