DAYS 1-5 (OCTOBER 29 – NOVEMBER 2)

No changes. High pressure dominates. The first area of high pressure sinks to the south of our region today allowing a warm-up. A cold front moves through with clouds tonight and early Friday and shifts the wind, and a cooler high pressure area moves in from Canada for the weekend, but not before Friday is another mild day waiting for a secondary boundary to move through later in the day before the cooler air starts to move in. For Halloween on Saturday, it will be clear, calm, and quickly cooling off in the evening with temps falling from highs in the 50s into and through the 40s, but without any notable wind. Daylight Saving Time ends and standard time returns on Sunday morning when 2:00 a.m. EDT becomes 1:00 a.m. EST. What once looked like a low pressure area to bring a rain chance Monday now looks like only a weak disturbance with some clouds around that day, but the weather currently looks dry.

TODAY: Sunny. Highs 62-69. Wind SW 5-15 MPH.

TONIGHT: Clouds move in. Lows 46-53. Wind SW 5-15 MPH.

FRIDAY: Clouds move out / sun returns. Highs 65-72. Wind SW shifting to NW 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Lows 33-40. Wind NW 5-15 MPH, higher gusts.

SATURDAY: Mostly sunny. Highs 55-62. Wind NW 5-15 MPH, diminishing.

SATURDAY NIGHT: Mostly clear. Lows 26-33 except 34-41 coastal & urban areas. Wind calm.

SUNDAY: Sun and high clouds. Highs 56-63. Wind variable up to 10 MPH.

SUNDAY NIGHT: Partly cloudy. Lows 38-45. Wind S under 10 MPH.

MONDAY: Variably cloudy. Highs 57-64. Wind variable up to 10 MPH.

DAYS 6-10 (NOVEMBER 3-7)

Greatest threat of wet weather is about November 6 in an otherwise mostly dry and mild pattern.

DAYS 11-15 (NOVEMBER 8-12)

Disturbance or two with potential unsettled weather in the November 10-12 period. Temperatures near to above normal.

DAYS 1-5 (OCTOBER 28 – NOVEMBER 1)

High pressure maintains control of our weather through the weekend. The only “interruption” will be two frontal boundaries that pass by during Friday, the first in the pre-dawn hours with some cloudiness and perhaps a sprinkle of rain, and the second later Friday with little fanfare other than a breeze and the introduction of a slightly cooler air mass after a prior warm-up. The weekend, which is one hour longer due to changing the clocks back 1 hour at 2:00 a.m. Sunday, will be dominated by high pressure, including Halloween evening which will be dry and cool with light winds for outdoor shenanigans.

TODAY: Sunny. Highs 55-62. Wind variable up to 10 MPH.

TONIGHT: Clear. Lows 32-39. Wind SW under 10 MPH.

THURSDAY: Sunny. Highs 62-69. Wind SW 5-15 MPH.

THURSDAY NIGHT: Clear. Lows 43-50. Wind SW 5-15 MPH.

FRIDAY: Sun / cloud mix. Highs 65-72. Wind SW shifting to NW 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Lows 33-40. Wind NW 5-15 MPH, higher gusts.

SATURDAY: Mostly sunny. Highs 58-65. Wind NW 5-15 MPH, diminishing.

SATURDAY NIGHT: Mostly clear. Lows 26-33 except 34-41 coastal & urban areas. Wind calm.

SUNDAY: Sun and high clouds. Highs 56-63. Wind variable up to 10 MPH.

DAYS 6-10 (NOVEMBER 2-6)

Trend has been for the disturbances in the pipeline to look less and less impressive, and therefore associated rain chances to become minimal for November 2 & 4, to the point we may be looking at just fair weather and above normal temperatures as a ridge of high pressure becomes dominant next week.

DAYS 11-15 (NOVEMBER 7-11)

Medium range guidance trends have switched to a trough passing through with unsettled early period, and perhaps another late period, with fair weather otherwise. Taking all this with salt grains as medium range guidance performance has been iffy. Doesn’t look overly chilly, and doesn’t look overly stormy.

DAYS 1-5 (OCTOBER 27-31)

A cold front moved through overnight. Other than some lingering higher clouds born of cool air advection over the mountains to our northwest and some low clouds coming off the ocean on the MA South Shore for a time this morning, we’ll see plenty of sun today but it will be notably cooler than yesterday. High pressure builds right over the region for a clear, calm, cold night tonight and a sunny day with a decent temperature recovery Wednesday. The high sinks to the south and we warm up a bit more Thursday into Friday. Low pressure passes to our north and drags two frontal boundaries through the region Friday and Friday night. The first doesn’t have much of a chill behind it so Friday will be mild. Cooler air will come in behind the second boundary for Saturday. Halloween Evening looks dry and pleasantly cool with fairly light wind at this time.

TODAY: Patchy clouds early, then sunny. Highs 52-59. Wind NW 5-15 MPH.

TONIGHT: Clear. Lows 28-35. Wind NW under 10 MPH.

WEDNESDAY: Sunny. Highs 55-62. Wind variable up to 10 MPH.

WEDNESDAY NIGHT: Clear. Lows 32-39. Wind SW under 10 MPH.

THURSDAY: Sunny. Highs 62-69. Wind SW 5-15 MPH.

THURSDAY NIGHT: Clear. Lows 43-50. Wind SW 5-15 MPH.

FRIDAY: Sun / cloud mix. Highs 65-72. Wind SW shifting to NW 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Lows 33-40. Wind NW 5-15 MPH, higher gusts.

SATURDAY: Mostly sunny. Highs 58-65. Wind NW 5-15 MPH, diminishing.

DAYS 6-10 (NOVEMBER 1-5)

High pressure hangs on for dry weather for the first day of November and the end of the weekend in which we switch from Daylight Saving Time to Standard Time (2:00 a.m. Sunday, clocks move to 1:00 a.m.). Disturbances bring wet weather chances November 2 and again November 4 and/or 5, but neither of these look too impressive with dominant high pressure to the north of our region.

DAYS 11-15 (NOVEMBER 6-10)

Indications for high pressure again becoming dominant with a mainly dry and seasonable to mild temperature pattern.

DAYS 1-5 (OCTOBER 26-30)

High pressure will be the dominant player in our weather this week with its position determining temperature. Initially, an area sinks just to our south today and allows a nice warm-up after a chilly start. A cold front moves through with some clouds but no rain this evening, and a new Canadian high brings dry, cooler weather for Tuesday and Wednesday before it also sinks to the south and results in a warm-up again for Thursday and Friday, although another cold front will pass by (dry again) during the day Friday.

TODAY: Sunny to partly cloudy. Highs 65-72. Wind SW 5-15 MPH.

TONIGHT: Partly cloudy. Lows 37-44. Wind SW to NW 5-15 MPH.

TUESDAY: Sunny. Highs 52-59. Wind NW 5-15 MPH.

TUESDAY NIGHT: Clear. Lows 28-35. Wind NW under 10 MPH.

WEDNESDAY: Sunny. Highs 55-62. Wind variable up to 10 MPH.

WEDNESDAY NIGHT: Clear. Lows 32-39. Wind SW under 10 MPH.

THURSDAY: Sunny. Highs 62-69. Wind SW 5-15 MPH.

THURSDAY NIGHT: Clear. Lows 43-50. Wind SW 5-15 MPH.

FRIDAY: Sun / cloud mix. Highs 60-67. Wind SW shifting to NW 5-15 MPH.

DAYS 6-10 (OCTOBER 31 – NOVEMBER 4)

High pressure brings fair and slightly cooler weather for the October 31 / November 1 weekend, with Halloween evening looking dry and pleasantly cool. A stronger high sets up to our north early next week and a couple disturbances passing south of it bring brief rain chances to our region on November 2 & 4.

DAYS 11-15 (NOVEMBER 5-9)

Indications for high pressure again becoming dominant with a mainly dry and seasonable temperature pattern although some variability in temperatures depending on positioning of high pressure.

DAYS 1-5 (OCTOBER 25-29)

High pressure #1 sits atop us to start today then sinks to the south making it a day that starts cold and turns milder, with plenty of sun. Tonight chills off again under a clear sky but the warm-up Monday is even more pronounced with a southwest wind, until a moisture-starved cold front switches the wind back to northwest Monday night and Canadian high pressure moves in to start the cycle over Tuesday into midweek as the dry, up-and-down temperature pattern continues!

TODAY: Sunny. Highs 60-67. Wind SW up to 10 MPH.

TONIGHT: Clear. Lows 36-43. Wind SW up to 10 MPH.

MONDAY: Sunny to partly cloudy. Highs 63-70. Wind SW 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Lows 37-44. Wind SW to NW 5-15 MPH.

TUESDAY: Sunny. Highs 52-59. Wind NW 5-15 MPH.

TUESDAY NIGHT: Clear. Lows 28-35. Wind NW under 10 MPH.

WEDNESDAY: Sunny. Highs 55-62. Wind variable up to 10 MPH.

WEDNESDAY NIGHT: Clear. Lows 32-39. Wind SW under 10 MPH.

THURSDAY: Sunny. Highs 60-67. Wind SW 5-15 MPH.

DAYS 6-10 (OCTOBER 30 – NOVEMBER 3)

High pressure shifts to the south and it is mild and dry October 30 but another moisture-starved front brings yet another Canadian high in for the October 31 / November 1 weekend with fair weather and a slight cool-down. Halloween Evening looks dry and pleasantly cool. Watch for low pressure from the west to bring a brief chance of rain about November 2 (may pass mostly to south) with another high bringing fair weather back to end the period.

DAYS 11-15 (NOVEMBER 4-8)

Unsettled weather potential early to mid period, then fair weather returns. Temperatures near normal.

DAYS 1-5 (OCTOBER 24-28)

High pressure is parked over our area for the weekend with light winds, a clear sky, chilly nights and milder afternoons – about as nice as it can get for late October. The high slips to the south Monday which features a more notable breeze but a stronger warm-up before a cold front passes through at night with nothing more than just some clouds (no rainfall). This will be followed by a cooler Canadian high pressure area for Tuesday and Wednesday with more dry weather.

TODAY: Sunny. Highs 55-62. Wind NW up to 10 MPH.

TONIGHT: Clear. Lows 33-40. Wind calm.

SUNDAY: Sunny. Highs 60-67. Wind SW up to 10 MPH.

SUNDAY NIGHT: Clear. Lows 36-43. Wind SW up to 10 MPH.

MONDAY: Sunny to partly cloudy. Highs 63-70. Wind SW 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Lows 37-44. Wind SW to NW 5-15 MPH.

TUESDAY: Sunny. Highs 52-59. Wind NW 5-15 MPH.

TUESDAY NIGHT: Clear. Lows 28-35. Wind NW under 10 MPH.

WEDNESDAY: Sunny. Highs 55-62. Wind variable up to 10 MPH.

DAYS 6-10 (OCTOBER 29 – NOVEMBER 2)

High pressure shifts to the south and it turns milder again October 29-30 but another moisture-starved front brings yet another Canadian high in for the October 31 / November 1 weekend with fair weather and a slight cool-down. Halloween Evening looks dry and cool at this point. Watch for low pressure from the west with a wet weather chance at the end of the period, based on current expected timing.

DAYS 11-15 (NOVEMBER 3-7)

Briefly fair, then some unsettled weather with high pressure to the north and low pressure moving through from west to east in our region – details TBD.

DAYS 1-5 (OCTOBER 23-27)

High pressure builds toward the region today with still some northerly breeze felt here between it and far-offshore storminess, but a nice day with plenty of sun and just a few possible passing fair weather clouds. High pressure sits atop our region with clear, chilly nights and sunny, pleasant days this weekend, and with the high shifting offshore we’ll enjoy a push of warmer air Monday before a dry cold front passes through later Monday and leads Canadian high pressure into our region with cooler but continued fair weather for Tuesday.

TODAY: Mostly sunny. Highs 52-59. Wind N 5-15 MPH.

TONIGHT: Clear. Lows 28-35 except 35-42 urban centers. Wind NW under 10 MPH.

SATURDAY: Sunny. Highs 52-59. Wind NW up to 10 MPH.

SATURDAY NIGHT: Clear. Lows 33-40. Wind calm.

SUNDAY: Sunny. Highs 58-65. Wind SW up to 10 MPH.

SUNDAY NIGHT: Clear. Lows 36-43. Wind SW up to 10 MPH.

MONDAY: Sunny to partly cloudy. Highs 61-68. Wind SW 5-15 MPH.

MONDAY NIGHT: A few clouds, then clear. Lows 35-42. Wind NW 5-15 MPH.

TUESDAY: Sunny. Highs 52-59. Wind NW 5-15 MPH.

DAYS 6-10 (OCTOBER 28 – NOVEMBER 1)

Dry stretch continues through the end of October with a possible brief interruption of rain showers from a frontal passage on October 30. Watching the very end of the period (November 1) for the approach of low pressure and a rain chance, but timing uncertain.

DAYS 11-15 (NOVEMBER 2-6)

Rain chance start of period, briefly fair, then unsettled weather chance follows as pattern is a little more active during the early days of November.

DAYS 1-5 (OCTOBER 22-26)

An offshore storm has made its closest approach early today, skirting Nantucket and Cape Cod with a little light rainfall and tossing its canopy of clouds back across much of our region. Now, the low will begin a northeastward acceleration away from our waters and toward Atlantic Canada through Friday. We’ll see a gusty northerly breeze on the back side of the system as it moves away. High pressure builds in for fair weather this weekend then heads offshore by Monday at which time a moisture-starved cold front will approach from the northwest with some clouds later Monday, but probably no shower activity.

TODAY: Any early-day light rain ends Outer Cape Cod / Nantucket. Increasing sunshine west to east. Highs 53-60. Wind NE to N 10-20 MPH, higher gusts especially in coastal areas.

TONIGHT: Clear. Lows 33-40. Wind N 5-15 MPH.

FRIDAY: Sun and passing clouds. Highs 51-58. Wind N 5-15 MPH.

FRIDAY NIGHT: Clear. Lows 28-35 except 35-42 urban centers. Wind NW under 10 MPH.

SATURDAY: Sunny. Highs 52-59. Wind NW up to 10 MPH.

SATURDAY NIGHT: Clear. Lows 33-40. Wind calm.

SUNDAY: Sunny. Highs 58-65. Wind SW up to 10 MPH.

SUNDAY NIGHT: Clear. Lows 36-43. Wind SW up to 10 MPH.

MONDAY: Sunny to partly cloudy. Highs 61-68. Wind SW 5-15 MPH.

DAYS 6-10 (OCTOBER 27-31)

Pattern trend is for mainly dry with high pressure in control early in the period, replaced by another Canadian high later in the period, with a quick frontal passage and rain shower chance between (later October 29 or early October 30.

DAYS 11-15 (NOVEMBER 1-5)

Watching for unsettled weather potentials around November 1-2 and again around November 4. Temperatures not far from seasonable albeit a bit variable.

DAYS 1-5 (OCTOBER 21-25)

High pressure remains to the north for a couple more days as an ocean storm spins to our southeast, making its closest pass tonight and early Thursday, at which time a little rain can occur in the Cape Cod region. After this, the storm will start to accelerate away toward Atlantic Canada and our northeasterly wind will shift more to the north to end the week. High pressure builds in for a very nice weekend!

TODAY: Increasing clouds. Highs 54-61. Wind NE 5-15 MPH with gusts 20-25 MPH inland, 15-25 MPH with gusts 30+ MPH coastal areas, strongest Cape Cod region.

WEDNESDAY NIGHT: Mostly cloudy. Periods of rain possible Cape / Islands and slight chance of rain MA South Shore to South Coast west of Cape Cod Canal. Lows 41-48. Wind NE 5-15 MPH except 15-25 MPH MA South Shore to South Coast including Cape / Islands with higher gusts.

THURSDAY: Increasing sun west to east. Highs 53-60. Wind NE to N 10-20 MPH, higher gusts particularly in coastal areas.

THURSDAY NIGHT: Mostly clear. Lows 33-40. Wind N 5-15 MPH, higher gusts.

FRIDAY: Partly cloudy. Highs 51-58. Wind N 10-20 MPH, higher gusts.

FRIDAY NIGHT: Mostly clear. Lows 31-38. Wind N to NW diminishing to under 10 MPH.

SATURDAY: Sunny. Highs 52-59. Wind NW up to 10 MPH.

SATURDAY NIGHT: Clear. Lows 33-40. Wind calm.

SUNDAY: Sunny. Highs 58-65. Wind SW up to 10 MPH.

DAYS 6-10 (OCTOBER 26-30)

Fair weather early next week. Unsettled weather chance middle of next week. Fair weather returns late week. This is the result of a hybrid pattern (transitional blocking) with west to east progression.

DAYS 11-15 (OCTOBER 31 – NOVEMBER 4)

Watching for unsettled weather potentials around November 1-2 and again around November 4, but low confidence forecast.

DAYS 1-5 (OCTOBER 20-24)

The high pressure north, storm at sea pattern continues for a few more days. The initial expected push of the offshore low north enough to throw a cloud shield across the sky later yesterday was weaker than forecast, and the cloud deck’s progress was weak and thwarted further by dry air. As a result, a mostly clear night resulted in a colder start this morning and also means more sunshine will be around today. Even tonight into Wednesday the cloud deck will struggle to push north and west initially, but will finally do so in a more notable way later Wednesday through early Thursday, when the storm makes its closest pass to New England, clouds enough to bring the chance of some light rainfall to Nantucket, Martha’s Vineyard, and Cape Cod, and perhaps a few sprinkles as far north and west as the MA South Shore to South Coast (west of the Cape Cod Canal). By later Thursday, the storm actively moves north northeast and its cloud deck departs. As the storm heads for Atlantic Canada late this week, an upper low’s western periphery will skirt our region on Friday with a cloud / sun mix but it looks like any convective precipitation associated with it will be up over Maine then track into the waters east of our region. Saturday’s weather should feature full sunshine as high pressure builds in for a nice start to the final full weekend of October.

TODAY: Limited sun Cape Cod / Islands, brighter sun filtered by high clouds at times elsewhere. Highs 56-63. Wind NE 5-15 MPH except 15-25 MPH Cape / Islands.

TONIGHT: Partly cloudy – most clouds Cape / Islands. Lows 38-45. Wind NE 5-15 MPH, except higher gusts Cape / Islands.

WEDNESDAY: Slow increase in high to middle clouds southeast to northwest, further limiting sunshine. Highs 55-62. Wind NE 5-15 MPH except 15-25 MPH Cape / Islands.

WEDNESDAY NIGHT: Mostly cloudy. Periods of rain possible Cape / Islands and slight chance of rain MA South Shore to South Coast west of Cape Cod Canal. Lows 41-48. Wind NE 5-15 MPH except 15-25 MPH MA South Shore to South Coast including Cape / Islands.

THURSDAY: Increasing sun west to east. Highs 53-60. Wind NE to N 10-20 MPH.

THURSDAY NIGHT: Mostly clear. Lows 33-40. Wind N 5-15 MPH, higher gusts.

FRIDAY: Partly sunny. Highs 51-58. Wind N 10-20 MPH, higher gusts.

FRIDAY NIGHT: Mostly clear. Lows 31-38. Wind N to NW diminishing to under 10 MPH.

SATURDAY: Sunny. Highs 52-59. Wind NW up to 10 MPH.

DAYS 6-10 (OCTOBER 25-29)

High pressure provides fair weather with a milder trend as it sinks to the south of the region early period. Watch for a cold frontal passage with maybe a rain shower sometime October 27-28 and a shot of cooler air to follow it in a generally zonal flow pattern.

DAYS 11-15 (OCTOBER 30 – NOVEMBER 3)

A little uncertain as to the pattern details end of October and start of November but for our sensible weather is currently looks dry to end the month, and maybe a brief interruption of unsettled weather somewhere in the first couple days of November as the westerly flow pattern is most dominant here. Temperatures would be up-and-down, but not extreme in either direction.

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.

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.
