Thursday Forecast

7:34AM

DAYS 1-5 (OCTOBER 31-NOVEMBER 4)
No big changes, as the wettest part of your October 31 is expected to be during the daylight hours as scattered to numerous rain showers move through in an increasing southerly wind, and then we see a diminishment of shower activity by evening as winds continue to increase, so that towns and cities still holding trick or treat will escape heavy soaking rainfall for the most part but will still have to deal with gusty winds, blowing leaves, and possible downed tree branches. Use caution if you will be out and advise caution if you are sending kids out. And this is a good place for a reminder to use extra care if you will be driving. Overnight, as a cold front approaches, one or two lines of showers and possible embedded thunderstorms will move across the region from west to east, and this is when some of the strongest wind gusts will occur, with potential tree damage and resultant localized power outages. When we get to dawn on Friday, the front will be moving offshore and we’ll see it clear out during the morning with sun and passing clouds the remainder of the day, and temperatures will be “upside-down”, starting fairly warm, ending up much cooler. The weekend continues to look dry, but we’ll actually have a fairly close call that many don’t even notice, as energy moving through from west to east almost catches up to an offshore disturbance Saturday night. A phase would have resulted in a period of rain/mix/snow in at least eastern areas, but it looks like this is not going to be the case. So dry weather should continue even if clouds move overhead, and then additional dry weather will round out the weekend and continue Monday as high pressure dominates.
Forecast details…
TODAY: Mostly cloudy. Scattered to numerous rain showers. Humid. Highs 63-70. Wind S 10-20 MPH, higher gusts.
TONIGHT: Mostly cloudy. Isolated rain showers evening. Numerous rain showers and possible thunderstorms arriving west to east overnight. Humid. Lows 60-67. Wind S 15-25 MPH, higher gusts into the 35-45 MPH range evening, gusts 40-50 MPH and locally stronger overnight.
FRIDAY: Mostly cloudy with rain showers likely around dawn then a sun/cloud mix. Highs 60-67 early, then falling through the 50s. Wind W 15-25 MPH, higher gusts.
FRIDAY NIGHT: Clearing. Lows 38-45. Wind W 10-20 MPH early, diminishing gradually.
SATURDAY: Sunny to partly cloudy. Highs 48-55. Wind NW 5-15 MPH becoming variable.
SATURDAY NIGHT: Variably cloudy. Lows 30-37. Wind variable up to 10 MPH.
SUNDAY: Mostly sunny. Highs 46-53. Wind W 10-20 MPH.
SUNDAY NIGHT: Clear. Lows 26-33 interior, 33-40 coastal and urban areas. Wind W under 10 MPH.
MONDAY: Sunny. Highs 48-55. Wind W 5-15 MPH.

DAYS 6-10 (NOVEMBER 5-9)
A west to east flow will dominate with a mean trough position temporarily in the Great Lakes to New England. This is a cooler but mainly dry pattern. Two disturbances will likely pass by, the first sometime late November 5 to early November 6 with nothing more than clouds, the second sometime November 7 with more cloudiness and a risk of showers, likely in the form of rain. Temperatures near to mostly below normal.

DAYS 11-15 (NOVEMBER 10-14)
High pressure should control the weather to start the period with a chill giving way to a moderation in temperature, then a turn to unsettled weather is possible during the second half of the period.

Wednesday Forecast

7:37AM

DAYS 1-5 (OCTOBER 30-NOVEMBER 3)
Low level moisture, still present, will be less in the form of a low overcast, fog, and drizzle today, and more in the form of considerable cloudiness, more humid air, and scattered rain showers, which will morph into a strong southerly air flow ahead of an approaching cold front Thursday, when more numerous rain showers will occur, but in waves, leaving a distinct possibility that towns that did not postpone trick or treat may be doing so in rain-free but windy and fairly warm conditions. If this is the case, even without rain, people will need to beware of many leaves on the ground, which can be slippery, and keep an eye around older trees for branches that may be vulnerable to stronger wind gusts. A final band of rain showers should come through in the pre-dawn hours of Friday, which will turn out to be an upside down temperature day, starting out quite warm for the first hours of November, then turning much cooler, along with a gusty westerly wind. The weekend looks mainly dry and on the chilly side. A very weak disturbance passing by Saturday night and early Sunday will not combine with offshore energy, so just some cloudiness and no more than a shower of rain or snow would occur, but probably north of the WHW area.
Forecast details…
TODAY: Mostly cloudy. Scattered rain showers. More humid. Highs 60-67. Wind SE to S 5-15 MPH.

SUNDAY: Mostly sunny. Highs 46-53. Wind W 10-20 MPH.

DAYS 6-10 (NOVEMBER 4-8)
General west to east flow. The only weather system of note should be a frontal system trailing from a low passing to the north between late November 6 and early November 7. Temperatures near to mostly below normal.

DAYS 11-15 (NOVEMBER 9-13)
A general west to east flow continues with another disturbance due about November 10. By the end of the period, a broader area of unsettled weather may arrive. Temperatures should show a moderating trend overall.

Tuesday Forecast

6:56AM

DAYS 1-5 (OCTOBER 29-NOVEMBER 2)
A blanket of low level moisture continues today into Wednesday as the light and prevailing surface wind gradually shifts from east to southeast. This means that pockets of drizzle will be around, favoring areas closer to the coast. But Wednesday, the risk of rain showers will increase as a trough approaches from the west and an area of mid level moisture moves in from the south. This will be a precursor to a stronger push of air from the south as the gradient increases between offshore high pressure and an approaching front from the west, parented by a strong low pressure area moving to the northwest of New England late Thursday then passing north of the area on Friday. What does this mean for the Halloween weather? Well with already talk of Halloween wash-outs I need to step in here and say “not so fast!” We are going to be dealing with showery rainfall, and as we get into the warm sector during Thursday, it’s very possible that large areas of rain-free conditions will exist, so we may end up with a window of opportunity for no rainfall during trick-or-treat time, however, the wind gusts may be a bigger issue, not that they will be severe, but we may be dealing with a lot of leaves blowing about, and wind-sensitive costumes and Halloween set-ups being impacted somewhat. I am not going to over-hype this potential, because I don’t think we’re looking at a major wind event, just a gusty Halloween night, maybe adding to the “spookiness”. So that leaves us only the rainfall issue to fine-tune, which we will do in the next 2 blog updates. On Friday, a strong cold front passes by, and a day that starts warm, humid, and showery will end dry, blustery, and much cooler. This sets us up for a mainly dry and chilly Saturday.
Forecast details…
TODAY: Mostly cloudy. Areas of drizzle and fog. Highs 53-60. Wind E to SE up to 10 MPH.
TONIGHT: Mostly cloudy. Isolated to scattered rain showers. Lows 45-52. Wind SE up to 10 MPH.
WEDNESDAY: Mostly cloudy. Scattered rain showers. Highs 60-67. Wind SE to S 5-15 MPH.
WEDNESDAY NIGHT: Mostly cloudy. Isolated rain showers. Lows 53-60. Wind S 5-15 MPH.
THURSDAY: Mostly cloudy. Scattered to numerous rain showers. Increasingly humid. Highs 63-70. Wind S 10-20 MPH, higher gusts.
THURSDAY NIGHT: Mostly cloudy. Isolated to scattered rain showers. Humid. Lows 60-67. Wind S 15-25 MPH, higher gusts.
FRIDAY: Mostly cloudy with rain showers likely early to mid morning. Sun/cloud mix late morning on. Highs 60-67 early, then falling through the 50s to the 40s. Wind SW 10-20 MPH shifting to NW with higher gusts.
FRIDAY NIGHT: Clearing. Lows 38-45. Wind NW 10-20 MPH.
SATURDAY: Sunny to partly cloudy. Highs 48-55. Wind NW 10-20 MPH.

DAYS 6-10 (NOVEMBER 3-7)
An offshore wave of low pressure and a polar jet disturbance come close to meeting but don’t quite make it, so early November 3 just brings a rain/snow shower risk instead of a period of precipitation, followed by dry/breezy/chilly weather. High pressure moves in for nice but cool weather November 4. The later November 5 to early November 7 period carries some uncertainty as another pair of disturbances (one offshore and one coming through the Great Lakes) have to be watched should they start to interact. Otherwise somewhere in there just a period of light precipitation is possible. A stronger cold air mass may arrive at the end of the period.

DAYS 11-15 (NOVEMBER 8-12)
Fair, chilly start then a moderating trend. Unsettled weather may approach by the end of the period.

Monday Forecast

7:02AM

DAYS 1-5 (OCTOBER 28-NOVEMBER 1)
The low pressure area that brought Sunday’s soaker is offshore, but not that far away, and is helping keep an onshore air flow going, combined with high pressure in eastern Canada, so low level moisture will keep clouds in place along with areas of drizzle and perhaps a few renegade rain showers today and Tuesday. Also, watch for some coastal flooding around high tide times from a combination of easterly fetch and astronomically high tides. As the air flow turns more southerly ahead of an approaching low pressure trough Wednesday, it will be a little milder but still clouds will dominate with a slightly better chance of rain showers. And then changes begin, but that doesn’t mean quick improvement. In fact, things get worse before they get better as a stronger trough and frontal system approach Thursday. Where last year’s Halloween night was pleasantly cool and dry, it looks like this one may end up mild but rather breezy and wet. Finally, a strong cold front passes by during Friday as November arrives, and a day that starts wet and mild will likely end colder and dry.
Forecast details…
TODAY: Mostly cloudy. Areas of drizzle and fog. Isolated rain showers possible. Highs 50-57. Wind NE to E up to 10 MPH.
TONIGHT: Mostly cloudy. Areas of drizzle and fog. Lows 43-50. Wind E up to 10 MPH.
TUESDAY: Mostly cloudy. Areas of drizzle and fog. Highs 53-60. Wind E to SE up to 10 MPH.
TUESDAY NIGHT: Mostly cloudy. Isolated to scattered rain showers. Lows 45-52. Wind SE up to 10 MPH.
WEDNESDAY: Mostly cloudy. Scattered rain showers. Highs 60-67. Wind SE to S 5-15 MPH.
WEDNESDAY NIGHT: Mostly cloudy. Isolated rain showers. Lows 53-60. Wind S 5-15 MPH.
THURSDAY: Mostly cloudy. Scattered to numerous rain showers. Highs 60-67. Wind S 10-20 MPH.
THURSDAY NIGHT: Cloudy. Numerous to widespread rain showers. Lows 53-60. Wind S 10-20 MPH, higher gusts.
FRIDAY: Mostly cloudy with rain showers likely morning. Sun/cloud mix afternoon. Highs 60-67 early, then falling through the 50s to the 40s. Wind SW 10-20 MPH shifting to NW with higher gusts.

DAYS 6-10 (NOVEMBER 2-6)
General westerly flow expected with a mostly dry and chilly November 2-3 weekend, though a disturbance passing through somewhere between late November 2 and early November 3 may produce a sprinkle of rain or flurry of snow in a few locations. Moderating temperatures occur later in the period and this transition may bring some cloudiness and light mix to rain later November 5, though timing is highly uncertain this far out.

DAYS 11-15 (NOVEMBER 7-11)
Best chance of unsettled weather comes at the start of the period before a transition from milder back to cooler weather again, with continued mostly dry weather and moderating temperatures once again late period.

Sunday Forecast

8:08AM

DAYS 1-5 (OCTOBER 27-31)
Low pressure moves northeastward through the interior Northeast, sending the triple-point of a warm front / cold front occlusion into New England where a new low will form by tonight over and just east of the region, then drift around out there and weaken early in the week. This introduces an unsettled stretch of weather to the region which will be wettest later today but will hang around in some form into if not through midweek, which includes Halloween on Thursday. Don’t read this and think we have 5 washed out days ahead. That’s not the case. This will be an unsettled stretch of weather, where we will be having to figure out details on lots of clouds and occasional wet threats.
Today’s is waves of lighter rain as warm air moves in aloft, and then numerous rain showers, some heavier, later day and evening as the front arrives and cyclogenesis ensues. Tomorrow’s weather will feature a lot of low level moisture, so an overcast day with drizzle and areas of fog and a risk of a few periods of rain seem likely. Things should ease up somewhat Tuesday into Wednesday with the decaying low offshore and a nose of high pressure from eastern Canada poking in, but still enough onshore flow that it may make any clearing hard to come by. Thursday well be watching the approach of a new system from the west, and earlier I’d been thinking we may get into a warmer southerly flow, but that may be prevented if a frontal boundary is not allowed to push northward enough. There is still the chance it does push through and we do get into the warm sector, and if that happens my temperature forecast below will be under-done. For now my thinking this far out is that any significant rainfall from that approaching system will be held off until very late Thursday night or even next Friday.
Forecast details…
TODAY: Mainly cloudy morning with spotty light rain. Overcast afternoon with increasing rain shower threat west to east, some of which may be moderate to heavy. Highs 55-62. Wind E-SE up to 10 MPH.
SUNDAY NIGHT: Cloudy. Areas of fog and drizzle. Rain likely. Lows 48-55. Wind SE to E 5-15 MPH.
MONDAY: Cloudy. Drizzle and areas of fog. Chance of rain. Highs 52-59. Wind NE up to 10 MPH.
MONDAY NIGHT: Cloudy. Area of drizzle and fog. Chance of rain. Lows 45-52. Wind E up to 10 MPH.
TUESDAY: Mostly cloudy. Patchy fog early. Chance of rain showers. Highs 55-62. Wind SE up to 10 MPH.
TUESDAY NIGHT: Mostly cloudy. Patchy fog. Lows 46-53. Wind SE up to 10 MPH.

THURSDAY: Cloudy. Highs 56-63. Wind E up to 10 MPH, possibly shifting to S.

DAYS 6-10 (NOVEMBER 1-5)
Low amplitude pattern, generally west to east flow, but mean trough position in Upper Midwest and Great Lakes. This pattern is cooler, and slightly less unsettled, but still systems moving through (the one mentioned before coming through November 1, and two weaker ones around November 2 and 4) bringing unsettled weather threats.

DAYS 11-15 (NOVEMBER 6-10)
Watching for a weather system and precipitation threat in the late November 6 to early November 8 time frame. Drier weather more likely thereafter.

Saturday Forecast

9:18AM

DAYS 1-5 (OCTOBER 26-30)
High pressure centered north of New England provides a nice day today. Low pressure will track northeastward, set to pass northwest of New England late Sunday, but its an occluding low and a new low center will form near or over southern New England Sunday night then doddle just offshore Monday as high pressure rebuilds to the north. This will provide an easterly air flow here, preventing much on the way of clearing. By Wednesday, the same general set-up but in weaker form will be in place, but we should see some improvement during the Tuesday-Wednesday time period.
Forecast details…
TODAY: Sun and high clouds. Highs 53-60. Wind N 5-15 MPH.
TONIGHT: Partly to mostly cloudy. Lows 38-45. Wind NE up to 10 MPH.
SUNDAY: Cloudy. Light rain likely morning. Spotty very light rain first half of afternoon. Numerous rain showers arriving west to east second half of afternoon. Highs 55-62. Wind E-SE up to 10 MPH shifting to S.
SUNDAY NIGHT: Cloudy. Areas of fog and drizzle. Rain likely. Lows 48-55. Wind SE to E 5-15 MPH.
MONDAY: Cloudy. Drizzle and areas of fog. Chance of rain. Highs 52-59. Wind NE up to 10 MPH.
MONDAY NIGHT: Cloudy. Area of drizzle and fog. Chance of rain. Lows 45-52. Wind E up to 10 MPH.
TUESDAY: Mostly cloudy. Patchy fog early. Chance of rain showers. Highs 55-62. Wind SE up to 10 MPH.
TUESDAY NIGHT: Mostly cloudy. Patchy fog. Lows 46-53. Wind SE up to 10 MPH.
WEDNESDAY: Partly sunny. Patchy fog early. Highs 58-65. Wind SE to S up to 10 MPH.

DAYS 6-10 (OCTOBER 31-NOVEMBER 4)
Close call between a gusty southerly breeze, fair weather and mild air and a cloudier, wetter scenario for October 31 depending on the track of low pressure west of New England and associated boundaries. Front passes through during November 1 with rain showers likely. Generally dry but breezy and much cooler November 2-3 weekend. Next wet weather threat comes at the end of the period.

DAYS 11-15 (NOVEMBER 5-9)
Watching for a weather system and precipitation threat in the late November 6 to early November 8 time frame.

Friday Forecast

6:44AM

DAYS 1-5 (OCTOBER 25-29)
A front moves in from the northwest today and tonight, bringing clouds back today and some rainfall, favoring areas north of I-90 tonight. High pressure from Canada presses southward Saturday returning dry weather and sun to the region, but a low pressure area moving northeastward will drag a warm front northward into the region Sunday which will be a grey day. The question has been how much rain will fall and when, and I still feel that we get an initial shot of rain with that warm front that then moves out of the region for a good part of the afternoon. A band of showers will approach from the west with a cold front as the initial low travels north of the region, but a new low will likely form as the system crosses the region with most of the wet weather late-day and evening of Sunday. That low will linger just offshore early in the week with additional unsettled weather.
Forecast details…
TODAY: Increasing clouds. Late-day light rain possible especially southern NH. Highs 57-64. Wind SW 5-15 MPH.
TONIGHT: Cloudy. Periods of light rain, favoring southern NH the northern half of MA. Lows 48-55. Wind SW 5-15 MPH.
SATURDAY: Partly sunny. Highs 52-59. Wind N 5-15 MPH.
SATURDAY NIGHT: Variably cloudy. Lows 35-42. Wind light N.
SUNDAY: Cloudy. Light rain likely morning and midday. Late-day rain showers likely. Highs 55-62. Wind E-SE up to 10 MPH shifting to S.
SUNDAY NIGHT: Cloudy. Areas of fog and drizzle. Rain likely. Lows 48-55. Wind S 5-15 MPH becoming variable.
MONDAY: Cloudy. Drizzle and areas of fog. Chance of rain. Highs 52-59. Wind NE up to 10 MPH.
MONDAY NIGHT: Cloudy. Area of drizzle and fog. Chance of rain. Lows 45-52. Wind NE up to 10 MPH.
TUESDAY: Cloudy. Areas of drizzle and fog. Chance of rain. Highs 52-59. Wind NE to E up to 10 MPH.

DAYS 6-10 (OCTOBER 30-NOVEMBER 3)
A frontal boundary will still be nearby and with low confidence leaning toward a few rain showers being around Wednesday to early Thursday then fair and milder later Thursday, with a stronger front pushing through from the west with additional rain showers Friday before the November 2-3 weekend is drier but breezy and rather cool.

DAYS 11-15 (NOVEMBER 4-8)
Progressive pattern expected. Next system brings a wet weather threat early in the period then fair and seasonably chilly weather follows.

Thursday Forecast

7:16AM

DAYS 1-5 (OCTOBER 24-28)
High pressure brings a great October day today. This high gives way to an approaching frontal boundary which will bring clouds in during Friday and a little wet weather at night, but this gets out of here by Saturday as another high pressure area moves in with nice weather again. The next low pressure system heads west of New England Sunday but upper winds will be transporting some of its moisture eastward while dry air tries to kill the system at the same time, meaning Sunday ends up mainly cloudy but leaving the question as to how wet it will get. What looks like plentiful rain on some guidance now may not turn out to be much during the day, and we may have to wait for a stronger frontal boundary at night to produce the most rainfall. Low pressure, although weak, redeveloping just offshore may hold clouds and some wet weather in here on Monday.
Forecast details…
TODAY: Mostly sunny. Highs 57-64. Wind W 5-15 MPH.
TONIGHT: Mostly clear. Lows 42-49. Wind SW 5-15 MPH.
FRIDAY: Increasing clouds. Late-day light rain possible. Highs 57-64. Wind SW 5-15 MPH.
FRIDAY NIGHT: Cloudy. Evening light rain likely. Lows 48-55. Wind SW 5-15 MPH.
SATURDAY: Partly sunny. Highs 52-59. Wind N 5-15 MPH.
SATURDAY NIGHT: Variably cloudy. Lows 35-42. Wind light N.
SUNDAY: Mostly cloudy. Chance of light rain. Highs 55-62. Wind E-SE up to 10 MPH shifting to S.
SUNDAY NIGHT: Mostly cloudy. Rain showers likely. Lows 48-55. Wind S 5-15 MPH becoming variable.
MONDAY: Cloudy. Drizzle and areas of fog. Chance of rain. Highs 52-59. Wind NE up to 10 MPH.

DAYS 6-10 (OCTOBER 29-NOVEMBER 2)
Additional unsettled weather possible October 29 as a frontal system pushes through from the west. Fair and cooler as high pressure moves in October 30. Fair, breezy, and milder as high pressure moves out October 31. Strong cold front passes by to start November with rain showers November 1 followed by windy/chilly weather later November 1 into November 2.

DAYS 11-15 (NOVEMBER 3-7)
Progressive pattern expected. High pressure brings fair/chilly weather November 3. Low pressure system brings threat of wet weather November 4 with fair and seasonably chilly weather returning thereafter.

Wednesday Forecast

6:51AM

DAYS 1-5 (OCTOBER 23-27)
Transition day, starting with clouds, fog, showers, and in some cases downpours over eastern MA and NH Seacoast area as the day dawns, but this all moves out during the morning and drier air arrives from the west during the day bringing clearing but fairly mild air to the area. High pressure builds in for a fabulous Thursday, and nice weather will linger into early Friday before a front approaches bringing clouds back and eventually some wet weather for Friday night. This will move out by early Saturday and high pressure will try to build in from the north but will never quite make it, but it should hold close enough and strong enough to keep the next threat of wet weather at bay until later Sunday, a potential set-up we’ve been uncertain about and keeping an eye on for some time.
Forecast details…
TODAY: Cloudy with areas of fog and rain showers, some heavy early morning. Clouds break, patchy fog, lingering showers mid morning. Clearing west to east late morning. Mostly sunny afternoon. Highs 60-67. Wind variable 5-15 MPH early, then W increasing to 10-20 MPH.
TONIGHT: Mostly clear. Lows 40-47. Wind W 10-20 MPH evening, diminishing overnight.
THURSDAY: Mostly sunny. Highs 57-64. Wind W 5-15 MPH.
THURSDAY NIGHT: Mostly clear. Lows 42-49. Wind SW 5-15 MPH.
FRIDAY: Increasing clouds. Late-day rain showers possible. Highs 57-64. Wind SW 5-15 MPH.
FRIDAY NIGHT: Cloudy. Rain showers likely. Lows 48-55. Wind SW 5-15 MPH.
SATURDAY: Mostly cloudy with rain possible early, then clearing. Highs 52-59. Wind N 5-15 MPH.
SATURDAY NIGHT: Mostly clear. Lows 35-42. Wind light N.
SUNDAY: Increasing cloudiness with late-day rain possible. Highs 52-59. Wind NE up to 10 MPH.

DAYS 6-10 (OCTOBER 28-NOVEMBER 1)
Low pressure bring wet weather to start October 28 before drier weather returns and lasts through the middle of next week, cool at first, then a warming trend through Halloween. The first of November may see the arrival of a strong cold front with a transition from mild to colder accompanied by some unsettled weather, but well into the future confidence is not high at this time.

DAYS 11-15 (NOVEMBER 2-6)
Low to borderline moderate confidence for pieces of the Midwest trough to make it into the Northeast with a chilly start and milder finish to this period, along with mostly dry weather to start and end with a wet weather threat mid period (about November 4).

Tuesday Forecast

7:24AM

DAYS 1-5 (OCTOBER 22-26)
Marine air paints today grey, and an approaching trough and associated warm front / cold front combo makes tonight and early Wednesday wet, but a drying westerly air flow brings bright weather back during the day Wednesday from west to east and sets up some nice weather for Thursday, the pick of the week, as high pressure moves in. The next trough brings cloudiness back on Friday, and eventually a wet weather threat by late-day or night, which may linger into Saturday before drier, cool air arrives from the north.
Forecast details…
TODAY: Mostly cloudy. Highs 53-60. Wind E 5-15 MPH.
TONIGHT: Mostly cloudy. Rain showers likely. Lows 45-52. Wind SE to S 10-20 MPH.
WEDNESDAY: Mostly cloudy early with rain showers possible, then mostly sunny. Highs 58-65. Wind W 10-20 MPH, higher gusts.
WEDNESDAY NIGHT: Mostly clear. Lows 40-47. Wind W 10-20 MPH evening, diminishing overnight.
THURSDAY: Mostly sunny. Highs 57-64. Wind W 5-15 MPH.
THURSDAY NIGHT: Mostly clear. Lows 42-49. Wind SW 5-15 MPH.
FRIDAY: Increasing clouds. Late-day rain showers possible. Highs 57-64. Wind SW 5-15 MPH.
FRIDAY NIGHT: Cloudy. Rain showers likely. Lows 48-55. Wind SW 5-15 MPH.
SATURDAY: Mostly cloudy with rain possible morning. Clearing afternoon. Highs 52-59. Wind N 5-15 MPH.

DAYS 6-10 (OCTOBER 27-31)
High pressure should bring fair weather October 27. The October 28-31 period is uncertain as a boundary may be nearby but playing it cooler than average to start with a risk of some unsettled weather from a disturbance to start the period, then somewhat drier with a gradual temperature moderation. this is a very low confidence forecast at this time.

DAYS 11-15 (NOVEMBER 1-5)
Low confidence here as well. Have to determine the strength and staying power of high pressure off the Atlantic Coast and an approaching trough digging into the Midwest. One or two opportunities for wet weather may present themselves, though they don’t look significant this far out, and it may start mild then trend cooler.

Monday Forecast

7:35AM

DAYS 1-5 (OCTOBER 21-25)
The remains of Nestor exit, dry air replaces that and today turns fairly nice, but an approaching trough and a surface east wind will turn Tuesday into a grey day, even if some areas start with sun, and then that trough will swing through with significant showers Tuesday night, but moving right along so that fair weather returns Wednesday and continues Thursday, thanks to an area of high pressure. By Friday, the next frontal system will approach with the return of clouds, and by Friday night we may be back into some wet weather once again.
Forecast details…
TODAY: Early rain showers possible southeastern MA. Clouds most dominant morning, sun most dominant afternoon. Highs 57-64. Wind NE to E up to 10 MPH.
TONIGHT: Partly cloudy. Lows 43-50. Wind E under 10 MPH.
TUESDAY: Mostly cloudy. Highs 53-60. Wind E 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Rain showers likely. Lows 45-52. Wind SE to S 10-20 MPH.
WEDNESDAY: Mostly cloudy early with rain showers possible, then mostly sunny. Highs 58-65. Wind W 10-20 MPH, higher gusts.
WEDNESDAY NIGHT: Mostly clear. Lows 40-47. Wind W 10-20 MPH evening, diminishing overnight.
THURSDAY: Mostly sunny. Highs 57-64. Wind W 5-15 MPH.
THURSDAY NIGHT: Mostly clear. Lows 42-49. Wind SW 5-15 MPH.
FRIDAY: Increasing clouds. Late-day or nighttime rain showers possible. Highs 57-64. Wind SW 5-15 MPH.

DAYS 6-10 (OCTOBER 26-30)
Cautiously optimistic about a dry October 26-27 weekend but will have to keep an area on 1 or 2 waves of low pressure on a front to the south, just in case. In either case, expect below normal temperatures. Brief unsettled weather possible about October 28 otherwise mainly dry and cool into the middle of next week as well.

DAYS 11-15 (OCTOBER 31-NOVEMBER 4)
Leaning toward a mainly dry pattern with a quick moderating trend then another cool-down.

Sunday Forecast

7:34AM

DAYS 1-5 (OCTOBER 20-24)
No changes today from yesterday’s outlook. High pressure gives way to the approaching low pressure remains of Nestor today, the center of which will pass southeast of New England early Monday with a risk of a period of rain mainly southeastern areas mainly late tonight and very early Monday. Fair weather returns with a sliver of high pressure over the region between departing Nestor remains and an approaching trough from the west. A surface easterly wind will bring in low level moisture for what likely turns out to be a cloudy Tuesday, but rain showers from the trough and associated surface low pressure area and warm front / cold front combo will hold off until Tuesday night and linger into early Wednesday. After this a drying westerly wind arrives during Wednesday and high pressure builds in for Thursday with fair weather.
Forecast details…
TODAY: Increasing cloudiness. Highs 58-65. Wind variable under 10 MPH.
TONIGHT: Cloudy. A period or two of rain possible favoring RI and southeastern MA. Lows 50-57. Wind variable up to 10 MPH.

DAYS 6-10 (OCTOBER 25-29)
High pressure moves offshore October 25 and a weak cold front approaches later in the day so this day would start chilly and dry followed by a quick warm-up and feature a rain shower threat to end it. Current thinking is this front will push offshore but October 26 may start with cloudiness as a wave of low pressure passes by, but high pressure from Canada should be strong enough to lean away from the unsettled weather risk somewhat. Still need to keep an eye on this being as far away as it is. The drier pattern may carry through the end of the period.

DAYS 11-15 (OCTOBER 30-NOVEMBER 3)
Continued medium range model differences and current leaning continues to be for the up and down temperature pattern with a risk of minor precipitation events in an overall dry pattern.

Saturday Forecast

7:56AM

DAYS 1-5 (OCTOBER 19-23)
High pressure provides a nice weekend for the most part. If you want lots of sun, today’s definitely the pick of the 2 days. We will have to encounter a small speed bump as the weekend comes to an end in the form of increasing clouds during Sunday and the risk of a period of rain especially in RI and southeastern MA. This will be due to the close pass of the low pressure remains of Tropical Storm Nestor, a fairly quick-moving tropical system from the Gulf of Mexico that is crossing the southeastern US at this time. This low will be slowing and turning more to the east from its northeastward track as it passes, keeping that rain threat to the south, but subsequently leaving some of its moisture in a position to be at least partially grabbed by a low pressure trough approaching New England from the west on Tuesday. Impact of this interaction will not be significant, but it may end up a little more than just a band of showers Tuesday night and early Wednesday, so while this doesn’t turn into a major event or anywhere near it, it may just be a little more noticeable than it would have been. However, before that happens, it looks like we squeeze in some decent and mild weather for much of Monday and even into Tuesday, with the latter dependent on how much low cloudiness forms and moves in from the southeast ahead of the next system. When we get to Wednesday, a cold front will sweep through early and the unsettled stuff will be pushed offshore, with fair and breezy weather arriving.

DAYS 6-10 (OCTOBER 24-28)
High pressure brings fair and seasonably cool weather October 24 before moving offshore with a warm-up October 25 after a chilly start. Weekend of October 26-27 carries the potential for unsettled weather but too far away for details. Drier, possibly colder end of period as behind any unsettled threat comes a push of chilly air from Canada.

DAYS 11-15 (OCTOBER 29-NOVEMBER 2)
Caution needed for the forecast this far out with one model pushing a colder picture while another reliable one says “not so fast”. When I see this happen, knowing the colder model tends to rush pattern changes, my leaning is toward and up-and-down temperature pattern with 1 or 2 opportunities for mostly minor precipitation events. Elaboration will take place when there is enough confidence for it.

Friday Forecast

7:14AM

DAYS 1-5 (OCTOBER 18-22)
Passing clouds and a gusty breeze are all that linger from our significant storm today, but we’re transitioning toward a very nice weekend. For sunshine, the pick of the weekend will be Saturday, and for temperatures, if you want milder, Sunday may have the slight edge, but they will really be close with two chilly mornings and somewhat milder afternoons. During this time, a tropical low pressure area from the Gulf of Mexico will be crossing the southeastern US and emerging off the Mid Atlantic Coast. Right now, it looks like all we see from this is some high level cloudiness at times Sunday and Monday, and perhaps some of its moisture getting pulled northward as a cold front approaches New England from the west by Tuesday of next week.
Forecast details…
TODAY: Partly to mostly sunny. Highs 56-63. Wind NW 10-20 MPH, higher gusts.
TONIGHT: Mostly clear. Patchy frost. Lows 35-42 except 40-47 immediate shore and urban areas. Wind W up to 10 MPH.
SATURDAY: Sunny. Highs 58-65. Wind W up to 10 MPH.
SATURDAY NIGHT: Clear. Lows 38-45. Wind light variable.
SUNDAY: Mostly sunny. Highs 61-68. Wind light variable
SUNDAY NIGHT: Partly cloudy. Lows 48-55. Wind S up to 10 MPH.
MONDAY: Partly sunny. Highs 63-70. Wind S 5-15 MPH.
MONDAY NIGHT: Mostly cloudy. Lows 50-57. Wind SE 5-15 MPH.
TUESDAY: Mostly cloudy. Rain showers likely. Highs 60-67. Wind SE to S 10-20 MPH.

DAYS 6-10 (OCTOBER 23-27)
Rain showers give way to clearing October 23 as a cold front passes. High pressure brings fair weather October 24-25, starting cool then warming up. Next disturbance in a westerly air flow is due by later October 26 with risk of rain showers, and should move along for dry weather at the end of the period.

DAYS 11-15 (OCTOBER 28-NOVEMBER 1)
A bit of a blocking pattern may try to develop driving a west-east elongated trough into the Upper Midwest, Great Lakes, and Northeast. Jury is out on how dynamic the pattern is, but overall it doesn’t look too strong, so the trend would probably be cooler but with limited unsettled weather and more dry than wet during this period.

Thursday Forecast

7:14AM

DAYS 1-5 (OCTOBER 17-21)
It was like winning the weather lottery here in southern New England, having a sharp disturbance about as strong as you can see this time of year combine with a rare shot of southern jet stream energy to form a rapidly intensifying low that then came right up overhead. Impressive winds and heavy rainfall was experienced, as expected. Instead of listing details in terms of rain amounts and wind gust reports, I will let you all discuss that in the comments and I will move along with the updated forecast, which has a few adjustments. Nothing really to change regarding the weather the next few days though. We’re not done with the storm system yet, as the center of it will be completing a tight cyclonic loop north of the Massachusetts border and then move eastward, exiting New England via Maine later today. This set-up will cause a strong westerly wind and wrap-around rain showers as the low departs. Drier air will work in tonight and especially Friday, although during this time we can expected a gusty breeze to continue. Then a nice break for the weekend as high pressure settles to the south and a warmer westerly air flow takes over, but there is a little change for Sunday’s outlook. A system coming out of the Gulf of Mexico is going to end up off the East Coast by the end of the weekend, and the overall pattern will be warped a bit from what it looked like earlier, with fair weather hanging on but possibly a more southerly or southeasterly air flow. When Monday comes, a more southerly flow is expected as high pressure to the north of the region also bridges southward just east of the region, keeping the low offshore at bay.
Forecast details…
TODAY: Variably cloudy. Scattered rain showers. Wind variable becoming W and increasing to 15-30 MPH with higher gusts.
TONIGHT: Partly to mostly clear. Lows 38-45. Wind NW 15-25 MPH, higher gusts.
FRIDAY: Mostly to partly sunny. Highs 56-63. Wind NW 10-20 MPH, higher gusts.
FRIDAY NIGHT: Clear. Patchy frost. Lows 35-42 except 40-47 immediate shore and urban areas. Wind W up to 10 MPH.
SATURDAY: Sunny. Highs 60-67. Wind W up to 10 MPH.
SATURDAY NIGHT: Clear. Lows 38-45. Wind light variable.
SUNDAY: Sunny. Highs 65-72. Wind SE 5-15 MPH.
SUNDAY NIGHT: Partly cloudy. Lows 50-57. Wind S up to 10 MPH.
MONDAY: Partly sunny. Highs 63-70. Wind S 5-15 MPH.

DAYS 6-10 (OCTOBER 22-26)
A little slower timing expected, with mild air and a risk of rain showers October 22, then a front pushing through with a drying/cooling trend October 23-24 before it warms back up ahead of the next front October 25. That front may bring some unsettled weather by October 26.

DAYS 11-15 (OCTOBER 27-31)
Overall westerly flow but indications are for a trend toward near to below normal temperatures with at least one threat of precipitation in an overall dry pattern. Leaning away from activity being added to by any moisture from the south as it looks like that will be lacking.
