DAYS 1-5 (OCTOBER 19-23)

The next 5 days will feature a pattern of high pressure to our north and low pressure to our south. The latter will be moving somewhat erratically in a blocking set-up, and its cloud shield will be in our sky later today into midweek, with its rain potentially reaching Cape Cod and the Islands for a brief time midweek. Otherwise, the system will remain offshore, although we’ll feel a gusty northeasterly breeze between it and the high to the north. By Friday, the low starts to move northeastward to a position well east of New England on its way to the outskirts of Atlantic Canada, at which time we’ll switch to a more northerly air flow.

TODAY: Sun becoming filtered by high clouds, also some lower clouds possible near the coast. Highs 57-64. Wind NE 5-15 MPH.

MONDAY NIGHT / TUESDAY: Partly cloudy to mostly cloudy. Lows 38-45. Highs 56-63. Wind NE 5-15 MPH except 15-25 MPH Cape Cod region.

TUESDAY NIGHT / WEDNESDAY: Lots of clouds. Late-day rain possible Cape Cod & Islands. Lows 40-47. Highs 53-60. Wind NE 10-20 MPH except 20-30 MPH South Coast region with higher gusts.

WEDNESDAY NIGHT: Mostly cloudy. Rain chance Cape Cod & Islands. Lows 41-48. Wind NE 10-20 MPH, higher gusts, especially Cape Cod & South Coast.

THURSDAY: Partly sunny. Highs 55-62. Wind NE 10-20 MPH.

THURSDAY NIGHT: Clearing. Lows 32-39. Wind N 10-20 MPH, higher gusts.

FRIDAY: Sun and passing clouds. Highs 52-59. Wind N 10-20 MPH, higher gusts, diminishing late in the day.

DAYS 6-10 (OCTOBER 24-28)

High pressure provides fair weather on the October 24-25 weekend and into early next week as well. Frontal system brings a rain shower chance toward the middle of next week in a more zonal flow pattern.

DAYS 11-15 (OCTOBER 29 – NOVEMBER 2)

Hybrid pattern may evolve with some transitional blocking but still a lot of west to east movement also. General idea is high pressure providing fair weather October 29-31 and an unsettled weather threat later in the period as we begin November.

DAYS 1-5 (OCTOBER 18-22)

A blocking pattern sets up during this 5-day period with high pressure overhead today then drifting just to our north, while low pressure organizes to our south. The idea is basically the same as previously discussed, with high pressure being dominant enough for dry weather here, but low pressure getting close enough at times to throw a cloud shield into the region, and maybe bring a period or two of rain to the South Coast region, particularly Cape Cod, at some point toward the middle of the coming week. After a tranquil day today when the high center is more overhead, after it moves to the north the air flow between it and the low pressure to the south will result in fairly persistent northeast winds in the days ahead.

TODAY: Sunny. Highs 52-59. Wind variable under 10 MPH.

TONIGHT: Clear. Lows 33-40. Wind N to NE up to 10 MPH.

MONDAY: Sun becoming filtered by high clouds, also some lower clouds possible near the coast. Highs 57-64. Wind NE 5-15 MPH.

MONDAY NIGHT / TUESDAY: Partly cloudy except mostly cloudy Cape Cod and South Coast with a chance of a period of rain on Cape Cod. Lows 38-45. Highs 56-63. Wind NE 5-15 MPH except 15-25 MPH Cape Cod region.

TUESDAY NIGHT / WEDNESDAY: Partly cloudy. Lows 40-47. Highs 55-62. Wind NE 10-20 MPH except 20-30 MPH South Coast region with higher gusts.

WEDNESDAY NIGHT / THURSDAY: Mostly cloudy. Chance of rain near the South Coast, especially Cape Cod region. Lows 41-48. Highs 54-61. Wind NE 10-20 MPH, higher gusts at times particularly coastal areas.

DAYS 6-10 (OCTOBER 23-27)

Blocking set-up transitions to a more zonal – west to east – flow pattern. Watch for frontal passages with shower threats around October 24 and again later in the period.

DAYS 11-15 (OCTOBER 28 – NOVEMBER 1)

Overall pattern favors zonal flow but there are still some hints on guidance of a slip back toward blocking with more low pressure evolving to our south, which we may have to watch for a closer pass at mid period. For now, continuing the theme of mostly dry with brief rain shower threats from passing systems from the west.

DAYS 1-5 (OCTOBER 17-21)

The cold front that went by last night has slowed as it moves off the coast enough so that a wave of low pressure holds some rainfall back in the South Coast region to start off the weekend, but this will move out and a gradual clearing trend will resume from northwest to southeast across the region during today. Along with this comes much cooler air and a gusty breeze. High pressure builds into the region tonight and Sunday. Winds drop off tonight and under a clear sky the temperature can fall below freezing in many inland locations, while staying a little higher than that in urban centers and along the ocean shore. Widespread frost is likely and there will be radiation fog over the warmer water of swamps and ponds, which often makes for very picturesque sunrises. Sunday will be filled with sunshine, light wind, and pleasant-feeling air after the very chilly beginning. Monday-Wednesday we’ll be watching an ocean storm to our south while high pressure drifts back to the north a little bit, putting our region in a northeasterly air flow. The low to the south will send its cloud shield into the sky, especially southern areas, from time to time, and some lower clouds can wheel in off the ocean at times on the northeast wind, but other than Cape Cod maybe getting clipped by rain briefly sometime between Monday night and Tuesday night, I expect the high pressure area to keep our region dry.

TODAY: Mostly cloudy morning including some rain South Coast, particularly Cape Cod and Islands region. Clearing trend follows this with increasing sun mixed with some passing fair weather clouds. Highs 48-55. Wind NW increasing to 15-25 MPH, gusts 30+ MPH.

TONIGHT: Clear. Lows 27-34 interior southern NH and central MA, 35-42 elsewhere, warmest urban centers and immediate coastal areas. Wind NW to N diminishing to under 10 MPH.

SUNDAY: Sunny. Highs 52-59. Wind variable under 10 MPH.

SUNDAY NIGHT: Clear. Lows 33-40. Wind N to NE up to 10 MPH.

MONDAY: Sun becoming filtered by high clouds, also some lower clouds possible near the coast. Highs 57-64. Wind NE 5-15 MPH.

MONDAY NIGHT / TUESDAY: Partly cloudy except mostly cloudy Cape Cod and South Coast with a chance of a period of rain on Cape Cod. Lows 38-45. Highs 56-63. Wind NE 5-15 MPH except 15-25 MPH Cape Cod region.

TUESDAY NIGHT / WEDNESDAY: Partly cloudy. Lows 40-47. Highs 55-62. Wind NE 10-20 MPH except 20-30 MPH South Coast region with higher gusts.

DAYS 6-10 (OCTOBER 22-26)

General large scale set-up is high pressure to the north, low pressure to the south of our area first half of period with a continued leaning toward dry weather with high pressure being dominant for our region. Pattern breaks down and transitions to a more zonal (west to east) flow later in the period. System from the west may bring showers by the end of the period.

DAYS 11-15 (OCTOBER 27-31)

West to east (zonal) flow pattern with up and down temperatures and brief rain shower chances. Best unsettled weather chances ~October 27 & 30.

DAYS 1-5 (OCTOBER 16-20)

A quick-moving low pressure area will pass north of our region today and tonight. It’s warm front brings us some rainfall this morning to midday before a break, with just a chance of a brief shower in the warm sector this afternoon. The low’s cold front will move across the region with showers and perhaps a thunderstorm – with the greatest chance of the latter being to the southwest of Boston (RI, eastern CT). The cold front will temporarily slow down as it exits, close enough for clouds to linger across the region and a shower chance to exist over southeastern areas into part of Saturday morning before it swings offshore. It will turn out to be a windy and much cooler day as well behind the departing front as its parent low intensifies in Atlantic Canada. High pressure builds toward the region with continued cool weather but diminishing winds as we move through the weekend. When we get to early next week we’ll see a blocking pattern that features high pressure to our north and low pressure to our south. The former should be close enough to keep our weather dry while the latter remains far enough south to keep rain away, though we may see its cloud shield in the sky, especially southern areas.

TODAY: Cloudy morning with a period of two of showers. Clouds can break for sun at times afternoon with a chance of a quick-passing shower. Highs 62-69. Wind SE up to 10 MPH early becoming SW 10-20 MPH afternoon.

TONIGHT: Mostly cloudy. Numerous showers west to east evening including the chance of a thunderstorm. Additional showers possible mainly east of I-95 and south of I-90 overnight. Lows 41-48. Wind SW 5-15 MPH shifting to NW 10-20 MPH with higher gusts.

SATURDAY: Mostly cloudy through late morning including a chance of additional showers South Coast to MA South Shore, then a sun / cloud mix. Highs 48-55. Wind NW 15-25 MPH, gusts 30 MPH or greater.

SATURDAY NIGHT: Partly cloudy, then clearing. Lows 27-34 interior southern NH and central MA, 35-42 elsewhere, warmest urban centers and immediate coastal areas. Wind NW diminishing to 5-15 MPH.

SUNDAY: Abundant sunshine. Highs 52-59. Wind NW 5-15 MPH, diminishing late in the day.

SUNDAY NIGHT: Clear. Lows 33-40. Wind W up to 10 MPH.

MONDAY: Sun becoming filtered by high clouds, also some lower clouds possible near the coast. Highs 57-64. Wind variable becoming E up to 10 MPH.

MONDAY NIGHT / TUESDAY: Partly cloudy. Lows 38-45. Highs 56-63. Wind E 5-15 MPH.

DAYS 6-10 (OCTOBER 21-25)

General large scale set-up is high pressure to the north, low pressure to the south of our area. Leaning toward high pressure in control enough for dry weather, but keeping watch on the potential for low pressure to get close enough to spread cloudiness and potential wet weather at least into southern areas. This pattern should hold through this period, so there is a lot of uncertainty in next week’s forecast at this time.

DAYS 11-15 (OCTOBER 26-30)

Return to a west to east (zonal) flow pattern with up and down temperatures and brief rain shower chances. Details TBD.

DAYS 1-5 (OCTOBER 15-19)

High pressure builds in today with fair, seasonable weather. Being on the easterly side of the high at first we’ll have an active breeze to start, along with some patchy clouds, but a trend to less wind and more sun with time. The high pressure area departs tonight and opens the door to our next round of unsettled weather. Low pressure will move quickly east northeastward out of the Midwest and Great Lakes across northern New England Friday and Friday night. Its warm front will bring us a period or two of rain Friday morning, and its cold front a round of showers in the evening, with maybe a few stray showers between. The low will then rapidly intensify as it moves into Atlantic Canada, which drags the coolest air mass of the season so far into our region on a gusty wind Saturday. The frontal boundary will become nearly parallel to the upper flow though as it moves off the South Coast Friday night into Saturday, and this will allow some cloudiness to linger into Saturday morning, including a rain shower threat in far southeastern areas. But this will be relatively short-lived and the balance of that day will feature sun and passing clouds across the region with well below normal temperatures, made to feel even colder by the gusty wind. High pressure builds into the region Saturday night and Sunday with slackening wind and dry but cool weather. The high will then sink to the south by Monday with a slightly milder westerly air flow and continued fair weather.

TODAY: Mostly sunny. Highs 57-64. Wind NW 5-15 MPH.

TONIGHT: Increasing clouds. Rain arrives west of I-95 pre-dawn. Lows 42-49. Wind variable to SE up to 10 MPH.

FRIDAY: Cloudy with rain and areas of fog morning. Clouds may break for sun at times afternoon with the chance of a quick-passing shower. Highs 62-69. Wind SE up to 10 MPH early becoming SW 10-20 MPH afternoon.

FRIDAY NIGHT: Mostly cloudy. Numerous showers west to east evening. A passing shower possible overnight. Lows 41-48. Wind SW 5-15 MPH shifting to NW 10-20 MPH with higher gusts.

SATURDAY: Mostly cloudy through mid morning including a chance of additional showers South Coast to MA South Shore, then a sun / cloud mix. Highs 47-54. Wind NW 15-25 MPH, gusts 30 MPH or greater.

SATURDAY NIGHT: Partly cloudy, then clearing. Lows 27-34 interior southern NH and central MA, 35-42 elsewhere, warmest urban centers and immediate coastal areas. Wind NW diminishing to 5-15 MPH.

SUNDAY: Abundant sunshine. Highs 55-62. Wind NW 5-15 MPH, diminishing late in the day.

SUNDAY NIGHT: Clear. Lows 35-42. Wind W up to 10 MPH.

MONDAY: Sunny. Highs 57-64. Wind W up to 10 MPH.

DAYS 6-10 (OCTOBER 20-24)

Some uncertainty has been introduced to the medium range period as guidance diverges greatly. Overall pattern suggest some blocking returning with high pressure from the US Northeast into southeastern Canada and low pressure off the Atlantic Coast well to the south. While some guidance keeps low pressure well out to sea later in the period, other guidance suggests it drifts in our direction later in the period. Will keep an eye on trends. Leaning mainly dry for now with maybe a late-period passing rain shower threat from a northern stream system

DAYS 11-15 (OCTOBER 25-29)

The blocking pattern may play a role early in the period, for now leaving it with an uncertain outlook. Trends are back to a zonal (west to east) flow toward month’s end.

DAYS 1-5 (OCTOBER 14-18)

Last night’s showers & thunderstorms have given way to this morning’s fog (in many areas mostly north of I-90) as a warm front lifted across the region, but it will dry out enough for sunshine to return to the areas that are fogged in, at least in part, during today, pushing temperature to warmer levels than what yesterday’s heavier overcast and onshore air flow allowed. We do have a cold front to pass through the region from west to east during this afternoon, and it may produce a quick-passing shower, so while it ends up a decent day to be outside, it’s still wise to look out for that potential quick interruption. This front will lead a seasonably cooler air mass into our region tonight and Thursday as high pressure builds in, making Thursday the “pick of the week” for sunshine, tolerable temperature, and relative tranquility – though there will be a breeze enough to notice. High pressure departs Thursday night and our next low pressure visit comes from the west during Friday. The low itself tracks north of our area late Friday. This track drags a warm front through our region Friday, preceded by some rainfall during the pre-dawn to midday window. I’ve been struggling with the timing of the cold front, which short range guidance has me nearly convinced it’s an evening passage west to east, when another round of showers is possible. Between this can come many rain free hours with some potential partial sunshine with breaks in the clouds in the low’s warm sector. As the cold front moves through then offshore early Saturday, it does temporarily slow enough so that some cloudiness will likely linger into Saturday morning, but any remaining shower activity should be confined to Cape Cod. Otherwise, Saturday will feature a sun / cloud mix and it will be much cooler along with a gusty wind. In fact, the temperature / wind combination is going to make it feel more like November. High pressure does push eastward, closer to the region, keeping it cool but relaxing the wind somewhat on Sunday, a day that will feature more sunshine.

TODAY: Clouds / fog across southern NH and northern MA to start the day with just patchy fog / clouds to the south, then a sun / cloud mix regionwide including the chance of a passing rain shower during the first half of the afternoon from west to east. Highs 67-74. Wind SW increasing to 5-15 MPH with higher gusts, shifting to NW by later in the day.

TONIGHT: Clearing. Lows 40-47. Wind NW 5-15 MPH.

THURSDAY: Mostly sunny. Highs 57-64. Wind NW 5-15 MPH.

THURSDAY NIGHT: Increasing clouds. Rain arrives west of I-95 pre-dawn. Lows 42-49. Wind variable to SE up to 10 MPH.

FRIDAY: Cloudy with rain and areas of fog morning. Clouds may break for sun at times afternoon. Highs 62-69. Wind SE up to 10 MPH early becoming SW 10-20 MPH afternoon.

FRIDAY NIGHT: Mostly cloudy. Showers most likely in the evening from west to east across the region. Lows 40-47. Wind SW shifting to NW 10-20 MPH, gusts 25 MPH or greater.

SATURDAY: Mostly cloudy early, then a sun / cloud mix. Highs 46-53. Wind NW 15-25 MPH, gusts 30 MPH or greater.

SATURDAY NIGHT: Partly cloudy, then clearing. Lows 27-34 interior southern NH and central MA, 35-42 elsewhere, warmest urban centers and immediate coastal areas. Wind NW diminishing to 5-15 MPH.

SUNDAY: Abundant sunshine. Highs 55-62. Wind NW 5-15 MPH, diminishing late in the day.

DAYS 6-10 (OCTOBER 19-23)

High pressure slides off to the southeast with a milder west to southwest air flow and fair weather early next week. Next disturbance / frontal system brings a shower chance later in the period.

DAYS 11-15 (OCTOBER 24-28)

Brief shower chance about October 24 or early October 25 with a passing frontal system. Unsettled weather chance returns later in the period. Temperatures variable, but not too far from seasonable.

DAYS 1-5 (OCTOBER 13-17)

The weather pattern is active with a lot to sort out over the next 5 days. So, let’s sort it out! Today we find ourselves overcast and considerably cooler than yesterday as a frontal boundary dropped south southwestward and introduced a light northeasterly air flow and cooler maritime air mass overnight with areas of drizzle and a few showers. As this front becomes stationary, it’s a running board for a couple of disturbances moving through from northwest to southeast today and tonight, bringing opportunities for showers, particularly over northern MA and southern NH, and even the chance of a thunderstorm tonight. The frontal boundary will lift northeastward allowing warmer air to return to our region on Wednesday before a final low pressure area goes by to our north and pulls the boundary back through as a cold front in the afternoon. Wednesday will see some sunshine unlike today, but there is also the chance of a shower with the final disturbance / frontal passage. High pressure builds into the region Thursday with fair weather, but scoots quickly out that night, opening the door to the next quick-moving low pressure area to impact our region on Friday. I continue to lean toward a low pressure track to our north, a warm frontal passage with a slug of rain in the morning, and a cold frontal passage with showers during the afternoon. The timing may be quick enough so that some partial clearing arrives from the west before sunset. There is some guidance that depicts this as a slower process with showers into the evening and clearing beginning later, so in leaning quicker I do keep my mind open that the evolution may be slower. Regardless of timing, the air mass following that system will be the coldest so far this autumn, along with quite a bit of wind to start our weekend off on Saturday, along with a sun / cloud mix and the chance of a passing rain shower – however rain could be mixed with wet snow in higher elevations with any showers.

TODAY: Cloudy. Areas of drizzle. Rain shower chance is greatest north of I-90, favoring northern MA and southern NH. Highs 54-61. Wind NE to E 5-15 MPH, a few higher gusts coastal areas and higher elevations.

TONIGHT: Mostly cloudy. Showers likely. Chance of a thunderstorm. Patchy fog. Lows 50-57 evening with a slow temperature rise later. Wind SE up to 10 MPH shifting to to SW.

WEDNESDAY: Partly sunny. Chance of a shower. Highs 67-74. Wind SW increasing to 5-15 MPH with higher gusts, shifting to NW by later in the day.

WEDNESDAY NIGHT: Clearing. Lows 40-47. Wind NW 5-15 MPH.

THURSDAY: Mostly sunny. Highs 57-64. Wind NW 5-15 MPH.

THURSDAY NIGHT: Increasing clouds. Rain arrives west of I-95 pre-dawn. Lows 42-49. Wind variable to SE up to 10 MPH.

FRIDAY: Cloudy with rain and areas of fog morning. Breaking clouds at times but numerous showers for a portion of the afternoon. Highs 58-65. Wind SE up to 10 MPH early, then SW 5-15 MPH with higher gusts.

FRIDAY NIGHT: A shower possible southeastern MA and RI early, otherwise partly cloudy. Lows 38-45. Wind NW 10-20 MPH, gusts 25-35 MPH.

SATURDAY: Sun / cloud mix. A passing rain shower possible which can be mixed with wet snow higher elevations of central MA and southwestern NH. Highs 46-53. Wind NW 15-25 MPH, gusts 30-40 MPH.

DAYS 6-10 (OCTOBER 18-22)

High pressure builds toward the region with diminishing wind and plenty of sun but chilly air to finish the weekend on October 18, then the high slides off to the southeast with a milder west to southwest air flow and fair weather early next week. Next disturbance / frontal system brings a shower chance later in the period.

DAYS 11-15 (OCTOBER 23-27)

Brief shower chance about October 24 with a passing frontal system. A more substantial rain chance later in the period as low pressure approaches from the west, based on current medium range pattern indications.

DAYS 1-5 (OCTOBER 12-16)

The swiftly-moving remains of Isaias still managed to bring over 1 inch of rain to many areas last night – a good slug of moisture and still-needed to continue to ease a longer-term precipitation deficit despite better rainfall since late summer. If today is a holiday for you, it will be rain-free one with improving conditions, and it will be quite mild with many areas making it to near 70 for high temps. We do have more weather changes on the way – not atypical for our area as we head deeper into autumn. Low pressure moves quickly in from the west northwest Tuesday bringing a frontal boundary into the region. Showers return and are most numerous north of I-90 with fewer to the south. The frontal boundary briefly pushes back to the north for part of Wednesday – the warmest day of the week – but then comes back through as a cold front with a possible shower later in the day. This leads a cooler air mass into our region for Thursday when dry weather is expected as high pressure moves into and across the region. But our quick-moving pattern indicates that the next low pressure area wastes no time getting here on Friday, a day that looks unsettled. The track of low pressure will determine details. At “day 5” there is a spread across guidance from a low that tracks to our south, bringing a cooler, steadier rain, and a low that tracks across northern New England or down the St. Lawrence Valley bringing us a period of rain with a warm front then a shower chance with a cold front, with a break in between. Other guidance brings the low right across the region with the resultant weather somewhere in-between the other two scenarios. For today’s update, the wording will be generalized, and the fine-tuning will then begin as it gets closer.

TODAY: Cloudy start including areas of fog, then clearing with sunshine returning. Highs 65-72. Wind N to NW up to 10 MPH.

TONIGHT: Clouds return north to south. Shower chance southern NH by dawn. Lows 48-55. Wind variable up to 10 MPH.

TUESDAY: Mostly cloudy. Showers likely north of I-90. Chance of showers to the south. Highs 58-65. Wind variable becoming E up to 10 MPH.

TUESDAY NIGHT: Mostly cloudy with a chance of showers evening. Partly cloudy with patchy fog overnight. Lows 50-57. Wind SE shifting to SW up to 10 MPH.

WEDNESDAY: Partly sunny. Chance of a shower. Highs 67-74. Wind SW increasing to 5-15 MPH with higher gusts, shifting to NW by later in the day.

WEDNESDAY NIGHT: Clearing. Lows 40-47. Wind NW 5-15 MPH.

THURSDAY: Mostly sunny. Highs 57-64. Wind NW 5-15 MPH.

THURSDAY NIGHT: Increasing clouds. Lows 40-47. Wind variable up to 10 MPH.

FRIDAY: Mostly cloudy. Showers likely. Highs 58-65. Wind variable 5-15 MPH.

DAYS 6-10 (OCTOBER 17-21)

Low pressure departs while intensifying, but an upper trough still has to cross the region early next weekend (October 17), so expect a windy day with a passing shower possible – with the potential for mix / wet snow in higher elevations with any showers. Later weekend (October 18) is cool, dry, and more tranquil as high pressure builds in. High pressure moves offshore October 19-20 with fair, milder weather before a frontal system brings a shower chance at the end of the period.

DAYS 11-15 (OCTOBER 22-26)

One frontal system departs early period and another crosses the region after mid period bringing brief unsettled weather in an otherwise mostly dry pattern with variable temperatures that don’t stray too far from normal.

DAYS 1-5 (OCTOBER 11-15)

The remains of Isaias will bring us a period of rain later today to the early hours of Monday as what is left of its low pressure area moves northeastward, elongating while passing south of our region. Drier weather returns Monday with some partial clearing, so it ends up not too bad a day overall. The next system dives east southeastward from Canada to bring us a chance of showers (maybe even a t-storm) later Tuesday, then exits into the western Atlantic with the return of dry weather to us for midweek, although I can’t rule out a quick shower Wednesday as a trough passes quickly through the region.

TODAY: Thickening clouds. Rain chances increase southwest to northeast by later in the day. Highs 60-67. Wind variable becoming S up to 10 MPH.

TONIGHT: Cloudy. Areas of fog. Periods of rain. Lows 53-60. Wind S shifts to E 5-15 MPH.

MONDAY: Mostly cloudy to partly sunny. Areas of fog and the chance of a shower early. Highs 60-67. Wind E shifts to N 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Patchy fog. Lows 47-54. Wind N shifts to W up to 10 MPH.

TUESDAY: Mostly cloudy. Showers likely, especially in the afternoon, including the chance of a thunderstorm. Highs 61-68. Wind W 5-15 MPH.

TUESDAY NIGHT: Cloudy. Showers likely. Lows 50-57. Wind W 5-15 MPH.

WEDNESDAY: Partly sunny. Chance of a shower. Highs 58-65. Wind NW 5-15 MPH, higher gusts.

WEDNESDAY NIGHT: Clearing. Lows 40-47. Wind NW 5-15 MPH.

THURSDAY: Mostly sunny. Highs 56-63. Wind NW 5-15 MPH.

DAYS 6-10 (OCTOBER 16-20)

A little faster timing on the next system which presents a wet weather threat October 16. A shot of chilly air is expected to follow this for the October 17-18 weekend along with gusty wind, especially Saturday. Upper low pressure passing through during this time can trigger a few rain showers, even some mix / snow shower activity in higher elevation locations. Fair and more tranquil weather follows this.

DAYS 11-15 (OCTOBER 21-25)

October 21-22 presents an unsettled weather threat based on current expectations / timing. Dry weather follows. Temperatures near to slightly below normal.

DAYS 1-5 (OCTOBER 10-14)

This is a 3-day weekend for many (if you work typical days and have Monday off) and the weather will be good to start, then slide downhill, only to recover slightly by the end of the 3-day period. High pressure sits atop our area now and made for a chilly but fairly calm start to the day, and it will be a pleasant day with not too much wind. Sunshine will become filtered much of the time through a veil of high cloudiness which is the northern reaches of the cloud deck associated with Isaias, which came ashore on the Gulf Coast last night as a category 2 hurricane. It has weakened quickly since then, already in the process before landfall due to strong wind shear, and of course typical overland weakening adding to that. The remains of this system, in mid latitude altered form, will bring heavier clouds into our region during Sunday and a batch of rain arriving during the afternoon, peaking in the evening and nighttime, and ending during Monday. An elongation of the upper low associated with the remains of this system means that showers may linger a little longer into Monday, though I am not expecting a steady rainfall that day. Partial clearing should be underway enough so that breaks of sun are possible before that day is over. A quick follow-up trough in the northern jet stream will approach and move into our region on Tuesday, bringing back plenty of cloud cover and some rainfall, likely showery in nature. There may be enough instability with this system to trigger a few thunderstorms. It all exits Wednesday with the return of dry weather, accompanied by a cool breeze.

TODAY: Sun becoming filtered by high clouds. Highs 61-68. Wind variable up to 10 MPH.

TONIGHT: High clouds dominate. Lows 35-42 inland low spots, 42-49 elsewhere. Wind variable under 10 MPH.

SUNDAY: Thickening clouds. Rain chances increase southwest to northeast by later in the day. Highs 60-67. Wind variable becoming S up to 10 MPH.

SUNDAY NIGHT: Cloudy. Areas of fog. Periods of rain. Lows 53-60. Wind S shifts to E 5-15 MPH.

MONDAY: Mostly cloudy. Areas of fog early. Chance of showers. Highs 60-67. Wind E shifts to N 5-15 MPH.

MONDAY NIGHT: Partial clearing. Patchy fog. Lows 47-54. Wind N shifts to W up to 10 MPH.

TUESDAY: Mostly cloudy. Showers likely, especially in the afternoon, including the chance of a thunderstorm. Highs 61-68. Wind W 5-15 MPH.

TUESDAY NIGHT: Cloudy. Showers likely. Lows 50-57. Wind W 5-15 MPH.

WEDNESDAY: Partly sunny. Chance of a shower mainly early in the day. Highs 58-65. Wind NW 5-15 MPH, higher gusts.

DAYS 6-10 (OCTOBER 15-19)

Passing disturbances / fronts can cause quick showers October 15, 17, and 19, but the overall pattern is dry with temperatures near to slightly below normal.

DAYS 11-15 (OCTOBER 20-24)

October 21-22 looks to be the greatest threat window for wet weather in an otherwise mostly dry pattern. Temperatures near to slightly below normal.

DAYS 1-5 (OCTOBER 9-13)

High pressure brings us fair weather today and Saturday. Low pressure from the midwest, infused with some moisture from what will remain of (current) Hurricane Isaias heading for the Gulf Coast will send clouds our way Sunday along with a Sunday night period of rain, which now appears it will exit first thing Monday as the bulk of the tropical moisture slides out to our south. Improving weather follows during Monday with another area of high pressure bringing fair weather early Tuesday before an approaching cold front brings back clouds and a shower chance by late Tuesday. Timing of that front is uncertain this far in advance but will be monitored and refined in future updates.

TODAY: Mostly sunny. Highs 60-67. Wind NW 5-15 MPH, higher gusts especially midday.

TONIGHT: Clear. Lows 33-40 except 38-45 immediate coast and urban centers. Wind N under 10 MPH.

SATURDAY: Sunny. Highs 62-69. Wind variable up to 10 MPH.

SATURDAY NIGHT: Clear. Lows 38-45. Wind calm.

SUNDAY: Increasing clouds. Highs 63-70. Wind S up to 10 MPH.

SUNDAY NIGHT: Cloudy. Rain likely. Lows 55-62. Wind SE 5-15 MPH.

MONDAY: Cloudy start with a chance of rain and areas of fog early, then clouds break for sun at times. Highs 62-69. Wind E shifting to N 5-15 MPH.

MONDAY NIGHT: Clearing. Lows 43-50. Wind W 5-15 MPH.

TUESDAY: Increasing clouds. Chance of showers late. Highs 61-68. Wind SW 10-20 MPH.

DAYS 6-10 (OCTOBER 14-18)

A shower chance can linger to early October 14 depending on the timing of a passing frontal system, otherwise turning dry and cool into the middle of next week. Watching for a shower potential around early October 16 and perhaps sometime during the October 17-18 weekend, but the deeper we get into this period the more uncertainty there is. The overall tendency is for most guidance to show dry over wet. Temperatures are not expected to stray too far from seasonable during this period of time.

DAYS 11-15 (OCTOBER 19-23)

Overall pattern looks dry – high pressure dominated, but we may again have to watch low pressure to our south with a tendency for some blocking to re-appear. Temperatures near to slightly below normal.

DAYS 1-5 (OCTOBER 8-12)

Low pressure cutting across southeastern Canada will drag a trough then a cold front across our region today. These boundaries, while advancing rather quickly, have little moisture to work with, thus limiting the shower chance with just isolated to scattered activity occurring along each boundary. Post cold front, there will be a quick clearing trend so that most areas from the I-95 belt westward end the day with abundant sunshine while the last of the clouds push through RI and southeastern MA with the last of any showers exiting those areas by sunset. While we have a mild day today, the breeze will be active, shifting from southwest to west, then northwest as each boundary moves through. Tonight and Friday see the delivery of a cooler air mass on a northwesterly breeze with dry weather. High pressure moves overhead Friday night, setting up radiational cooling under a clear sky with calm wind. This leads to the chance of frost again mainly in areas away from the coast and urban centers. Saturday itself will feature plenty of sun and a nice temperature turn-around after the chilly start. High pressure slides off to the northeast by Sunday when we’ll see increasing cloud cover ahead of incoming low pressure. This system, a combination of a mid latitude system from the west and tropical moisture associated with whatever remains of Hurricane Isaias in the Gulf – expected to make landfall on the Gulf Coast this weekend. While the storm will rapidly weaken once it does that, the moisture plume associated with it will join the system from the west and bring us a period of rain Sunday night into Monday before exiting the region. Based on current projections, I am not expecting that system to be excessive in terms of rainfall, and not a strong wind event either. I will monitor trends for a more precise timing prediction and refine that soon.

TODAY: Variably cloudy morning-midday with passing showers possible. Partly to mostly sunny remainder of day with a slight chance of an additional shower RI & southeastern MA mid to late afternoon. Highs 67-74. Wind SW shifting to W and eventually NW 10-15 MPH, higher gusts of 20-30 MPH.

TONIGHT: Mostly clear. Lows 42-49. Wind NW 5-15 MPH, higher gusts during the evening.

FRIDAY: Mostly sunny. Highs 60-67. Wind NW 5-15 MPH, higher gusts especially midday.

FRIDAY NIGHT: Clear. Lows 33-40 except 38-45 immediate coast and urban centers. Wind N under 10 MPH.

SATURDAY: Sunny. Highs 62-69. Wind variable up to 10 MPH.

SATURDAY NIGHT: Clear. Lows 38-45. Wind calm.

SUNDAY: Increasing clouds. Highs 63-70. Wind S up to 10 MPH.

SUNDAY NIGHT: Cloudy. Rain likely. Lows 55-62. Wind SE 5-15 MPH.

MONDAY: Cloudy with rain and areas of fog early, then mostly cloudy. Highs 62-69. Wind E shifting to N 5-15 MPH.

DAYS 6-10 (OCTOBER 13-17)

Shower chance October 13 with cold front crossing the area. Fair, breezy, cool October 14 then continued fair and more tranquil later next week as high pressure builds in.

DAYS 11-15 (OCTOBER 18-22)

Rain chance early in the period, then a drier pattern returns. Temperatures near to below normal.

DAYS 1-5 (OCTOBER 7-11)

High pressure overhead provided the clear & calm conditions for the coldest early morning of the season so far, with some inland low elevations receiving their first frost. For major stations, your cold spots were Taunton & Martha’s Vineyard at 32 as of 6 a.m., with typically “warmer” Logan Airport in Boston at 46. This is a good opportunity to point out the difference that can exist on a morning like this between Martha’s Vineyard (32) and Nantucket (44), because the latter’s station is exposed to much more ocean influence while the former’s temperature sensor sits in a relative “bowl” mid island where the wind can go calm and any warmth radiates out quickly, allowing the denser colder air to sink into the relative low spot. Always interesting. Anyway, high pressure slips offshore today and after our chilly start abundant sunshine warms is up notably by this afternoon as a southerly wind develops. Thursday looks like a mild day, but low pressure crossing southeastern Canada will drag its cold front across our region, maybe with a shower between mid morning and early afternoon, before we clear out. This is slightly faster timing than previously expected, but still it’s a moisture-starved front so any shower activity will be limited, and brief where it does occur. Some short-range high-resolution guidance pops a few additional showers later in the afternoon in the RI / southeastern MA area, but I’m not sure if this will occur. It may end up as more of a glorified deck of clouds and a few sprinkles, but we’ll keep an eye on that, just in case. Either way, a slightly cooler air mass arrives late Thursday into late week with another Canadian high bringing fair weather Friday into the weekend. When we get to Sunday, expect an increase cloud cover ahead of approaching low pressure. What is uncertain about Sunday (day 5) is how quickly the next system approaches. Some of it has to do with what is going on in the western Gulf where a new tropical system is getting organized. Now Tropical Storm Isaias, the system is expected to become the Atlantic Basin’s first hurricane of the 2026 season – as you know very very late compared to “typical” in this El Nino-snuffed season. The storm is expected to track northeast then north and make a landfall somewhere between Louisiana and Alabama by early Saturday, probably as a weakening system encountering wind shear. Regardless, plenty of remaining moisture from the system will be drawn northward into the trough and storm system heading our way, and the various guidance differs on timing of when that rain arrives here. The earlier scenario on some guidance has wet weather here as early as Sunday afternoon, while many models hold it off until nighttime for even Monday. I am leaning toward the mid-timed to later-timed scenario this far in advance but will monitor trends. So for now, Sunday’s outlook is for a rain-free day.

TODAY: Sunny. Highs 60-67. Wind variable up to 10 MPH morning, S to SW 5-15 MPH afternoon.

TONIGHT: Mostly clear except increasing low clouds and areas of fog near the South Coast. Lows 45-52 by late evening but may rise slightly overnight. Wind SW 5-15 MPH.

SUNDAY: Increasing clouds. Highs 63-70. Wind S up to 10 MPH.

DAYS 6-10 (OCTOBER 12-16)

Rain chance October 12 with low pressure passing by the region – details TBD. Shower chance October 13 with cold front crossing the area. Fair, breezy, cool October 14 then continued fair and more tranquil later next week as high pressure builds in.

DAYS 11-15 (OCTOBER 17-21)

Unsettled weather chance early and again late period but overall pattern is mostly dry with temperatures near to slightly below normal.

DAYS 1-5 (OCTOBER 6-10)

High pressure builds in today, delivering a cool Canadian air mass on a gusty breeze. The high crests over our region tonight which will be clear, calm, and colder – resulting in the first frost for some inland low spots. The high then slides offshore Wednesday into Thursday with fair weather and a milder trend, but a cold front will move through during Thursday with some passing clouds and maybe a brief shower (the only rain chance in this 5-day forecast period). Fair, slightly cooler weather returns behind this front late week / start of weekend.

TODAY: Mostly sunny. Highs 56-63. Wind NW to N 5-15 MPH.

TONIGHT: Clear. Patchy frost inland low elevations. Lows 36-43 except 43-50 urban centers and immediate coast. Wind calm.

WEDNESDAY: Sunny. Highs 60-67. Wind variable up to 10 MPH morning, S to SW 5-15 MPH afternoon.

WEDNESDAY NIGHT: Mostly clear. Lows 42-49. Wind SW 5-15 MPH.

THURSDAY: Sun and passing clouds. Slight chance of a brief shower. Highs 67-74. Wind SW to NW 5-15 MPH, higher gusts.

THURSDAY NIGHT: Mostly clear. Lows 42-49. Wind NW 5-15 MPH.

FRIDAY NIGHT: Clear. Lows 40-47. Wind N under 10 MPH.

SATURDAY: Sunny. Highs 60-67. Wind variable up to 10 MPH.

DAYS 6-10 (OCTOBER 11-15)

Dry 10/11 but increasing clouds. Watching a potential low pressure impact with a rain chance for 10/12 before a stretch of fair weather follows that. Temperatures near to slightly above normal.

DAYS 11-15 (OCTOBER 16-20)

Unsettled weather threat mid period, otherwise dry much of the time. Temperatures near to slightly above normal.

DAYS 1-5 (OCTOBER 5-9)

An ocean breeze yesterday deposited some higher moisture levels in our area, and a calmer wind overnight allowed a lot of stratus clouds to form, and in some areas patches of fog. This will break up as the sun rises today to reveal a sun / cloud mix as a cold front sweeps across the region from northwest to southeast. I am not expecting any rainfall with the front, just a quick pick-up of wind from the southwest, which will then shift to northwest. This allows us to get milder today before a cooler air mass arrives. We feel that cool shot during the day Tuesday, which will have plenty of sun but a cool breeze and temperatures that fail to hit 60 or barely get there where they do. The breeze drops off as high pressure moves overhead at night and sets up the coldest night of the young autumn season so far, with inland lower elevations potentially seeing their first frost of the season Wednesday morning, before we rebound to a milder afternoon with abundant sun that day. On Thursday, a brief warm-up occurs before another moisture-started cold front switches the wind back to northwest and delivers slightly cooler air for Friday.

TODAY: Lots of clouds and patchy fog early, then a sun / cloud mix. Highs 62-69. Wind SW quickly increasing to 5-15 MPH with gusts over 20 MPH, shifting to NW.

TONIGHT: Clear. Lows 40-47 except 45-52 urban centers. Wind NW 5-15 MPH.

TUESDAY: Mostly sunny. Highs 56-63. Wind NW to N 5-15 MPH.

TUESDAY NIGHT: Clear. Patchy frost inland low elevations. Lows 36-43 except 43-50 urban centers and immediate coast. Wind calm.

WEDNESDAY: Sunny. Highs 60-67. Wind variable up to 10 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 42-49. Wind SW 5-15 MPH.

THURSDAY: Sun and passing clouds. Highs 66-73. Wind SW to NW 5-15 MPH, higher gusts.

THURSDAY NIGHT: Clearing. Lows 42-49. Wind NW 5-15 MPH.

FRIDAY: Mostly sunny. Highs 60-67. Wind NW 5-15 MPH.

DAYS 6-10 (OCTOBER 10-14)

Saturday 10/10 & Sunday 10/11 look dry, sunniest Saturday followed by increasing cloud cover Sunday. We’ll be watching low pressure to our southwest that may receive an infusion of Gulf moisture and bring a rain chance to our region October 11 and/or 12 followed by clearing toward the middle of next week. Temperatures somewhat variable but averaging near to slightly above normal.

DAYS 11-15 (OCTOBER 15-19)

One unsettled weather threat somewhere mid to late period, otherwise mostly dry for much of this period. Temperature near to slightly above normal.
