Tuesday Forecast

7:22AM

DAYS 1-5 (OCTOBER 16-20)
A new weather pattern has arrived and this one will feature frequent shots of chilly air. A cold front moved through last night with some fanfare in the form of downpours and gusty winds, which lasted for several hours after the downpours, but will settle down during the day. Another cold front will charge across the region Wednesday evening and introduce air more seasonable for late November or early December for Thursday. A temperature moderation will follow this but the next wave of chilly air will be approaching during Saturday which may end up a little unsettled with a rain shower threat. Forecast details…
TODAY: Mostly sunny. Highs 51-58. Wind W 10-20 MPH with higher gusts, gradually diminishing during the day.
TONIGHT: Mostly clear. Lows 37-44. Wind SW 5-15 MPH.
WEDNESDAY: Mostly sunny to partly cloudy. Highs 54-63. Wind SW 10-20 MPH.
WEDNESDAY NIGHT: Variably cloudy. A passing rain shower possible early. Lows 34-40. Wind SW 10-20 MPH shifting to NW with higher gusts.
THURSDAY: Sun and passing clouds. Highs 42-49. Wind NW 15-25 MPH, higher gusts. Wind chill from the upper 20s to middle 30s.
FRIDAY: Sunshine and high clouds. Lows from the upper 20s to middle 30s. Highs in the 50s.
SATURDAY: Variably cloudy. Chance of rain showers. Lows from the middle 30s to lower 40s. Highs from the upper 50s to middle 60s.

DAYS 6-10 (OCTOBER 21-25)
A windy, chilly October 21 behind a cold front. Fair with moderating temperatures October 22. An early rain shower threat then breezy and cooler October 23 as another front passes. This front may settle just south of the region with a low pressure area on it so will have to watch for nearby unsettled weather at the end of the period in case it ends up further north.

DAYS 11-15 (OCTOBER 26-30)
Fair and generally seasonable to start the period. There have been signals on some guidance for a possible East Coast storm late in this period but cannot say with any confidence whether or not this will occur. Something to monitor going forward.

Monday Forecast

7:23AM

DAYS 1-5 (OCTOBER 15-19)
Once upon a time the was a hurricane named Sergio in the Pacific Ocean. He crossed the Baja and the southwestern US, produced wintry weather in the Rockies and severe weather in the Plains and Midwest. He’s much weaker than he once was but still can run pretty fast. Today his jog takes him from the Great Lakes to southeastern Canada, but along the way he’s picked up a warm front and a cold front, that dangle from him as he moves along. That warm front will bring a round of showers to the region this morning and midday and that cold front will slide across the region tonight producing showers and even a few thunderstorms. Once Sergio has departed for distant lands the door will be open for a fresh chilly air mass from Canada. This arrives overnight and during Tuesday as high pressure scoots across the Great Lakes and Ohio Valley. This high then goes south of the region Wednesday which briefly and slightly moderates, but is still a cool day nevertheless, but mild in comparison to the air mass that arrives behind the next cold front, which passes during Wednesday night. Thursday will be quite chilly and breezy, feeling more like a day in the middle of November. You’d be fooled more readily if the leaves were still not to peak color and still on the trees. But even this brief sting will be short-lived as it moderates again Friday. But suffice it to say we have entered a much cooler weather pattern in comparison to what we had going on for quite some time. Forecast details…
TODAY: Clouding over west to east early to mid morning. Rain showers arriving west to east mid to late morning through midday before tapering off to isolated showers. Clouds may break for sun at times during the mid to late afternoon. Highs 58-66 occurring late-day. Wind light variable this morning, S 5-15 MPH this afternoon, gusting 20-25 MPH by late in the day.
TONIGHT: Mostly cloudy. Showers and possible thunderstorms crossing the region west to east. A few brief downpours with gusty wind possible, especially eastern CT, eastern MA, and RI. Humid evening, drying overnight. Temperatures steady in the 60s may even rise briefly evening. Lows 43-50 by dawn. Wind SW 10-20 MPH, higher gusts possible, shifting to NW from west to east.
TUESDAY: Mostly sunny. Highs 51-58. Wind W 10-20 MPH, higher gusts possible.
TUESDAY NIGHT: Mostly clear. Lows 37-44. Wind SW 5-15 MPH.
WEDNESDAY: Mostly sunny to partly cloudy. A passing rain shower possible evening. Highs 54-63. Wind SW 10-20 MPH.
THURSDAY: Sun and passing clouds. Windy. Lows in the 30s. Highs in the 40s.
FRIDAY: Sunshine and high clouds. Lows from the upper 20s to middle 30s. Highs in the 50s.

DAYS 6-10 (OCTOBER 20-24)
Weekend of October 20-21 starts milder with a rain shower risk Saturday then turns breezy and chilly again Sunday. Fair October 22 then a rain shower risk as the next front passes October 23. This front may settle just south of the region with a low pressure area on it so will have to watch for nearby unsettled weather at the end of the period in case it ends up further north.

DAYS 11-15 (OCTOBER 25-29)
Fair and generally seasonable to start the period. There have been signals on some guidance for a possible East Coast storm late in this period but cannot say with any confidence whether or not this will occur. Something to monitor going forward.

Sunday Forecast

7:24AM

DAYS 1-5 (OCTOBER 14-18)
Quick update here, basically moving yesterday’s forecast forward with a few tweaks. High pressure slips south of the region today. Sunshine will be about today but it will be filtered by high cloudiness as some warmer air arrives above us. Low pressure (former Sergio), tracks north of New England late Monday, pushing a warm from through first, then a cold front through in the evening, with a couple rounds of showers, one with each front. A dry and chilly northwesterly air flow follows this Tuesday through midweek, reinforced by a second cold front passing by late Wednesday. Forecast details…
TODAY: Sun and high clouds. Highs 56-62. Wind W up to 10 MPH.
TONIGHT: Partly cloudy. Lows 40-47. Wind light SW.
MONDAY: Variably cloudy. A couple episodes of rain showers. Highs 58-65. Wind SW increasing to 10-20 MPH.
MONDAY NIGHT: Mostly cloudy with rain showers likely evening. Clearing overnight. Lows 44-52. Wind SW 10-20 MPH shifting to NW.
TUESDAY: Partly cloudy to mostly sunny. Highs 53-59. Wind NW 10-20 MPH, higher gusts.

DAYS 6-10 (OCTOBER 19-23)
Dry with a cold start and milder finish to October 19. Weekend of October 20-21 starts milder then turns breezy/chilly again as a cold front bisects it but probably produces little or no precipitation in the process. Fair, slight moderation in temperature late in the period.

DAYS 11-15 (OCTOBER 24-28)
A wet weather threat possible around October 24-25 followed by mostly dry weather. Temperatures near to below normal.

Saturday Forecast

8:14AM

DAYS 1-5 (OCTOBER 13-17)
A disturbance moving rapidly west to east across the region this morning and midday with cover the area with a canopy of cloudiness and also produce some periodic rain, but this will move out in quick fashion leaving behind only the risk of an isolated instability shower popping up in a few locations as colder air arrives aloft during the afternoon. This sets up a chilly Saturday night. Can’t rule out patchy frost over interior low elevations although with recent warmth, the ground may be just too warm to support much in the way of it. High pressure dominates, its center passing south of the region, with plenty of sun and a slightly milder afternoon after a cold start Sunday. Things are moving along quickly and the low pressure area that was once Sergio, a Pacific tropical system, will pass northwest of New England late Monday dragging a rain shower-producing cold front through the region. A dry and cool northwesterly air flow follows this front for Tuesday, with a second cold front approaching by later Wednesday. Forecast details…
TODAY: Mostly cloudy with periods of rain morning-midday. Sun and passing clouds with a risk of an isolated rain shower early through mid afternoon. Complete clearing late-day. Highs 52-58. Wind W 5-15 MPH.

WEDNESDAY: Mostly sunny to partly cloudy. Lows from the lower to middle 40s. Highs from the middle to upper 50s.

DAYS 6-10 (OCTOBER 18-22)
Breezy/dry/chilly October 18 with a delivery of Canadian air. Westerly flow, dry and a little milder October 19. Weekend of October 20-21 starts milder then turns breezy/chilly again as a cold front bisects it but probably produces little or no precipitation in the process. Fair, slight moderation in temperature end of period.

DAYS 11-15 (OCTOBER 23-27)
A wet weather threat possible around October 24-25 otherwise generally dry early and late period. Temperatures near to below normal.

Friday Forecast

7:30AM

DAYS 1-5 (OCTOBER 12-16)
The post-tropical version of Michael passes just south of New England today and has spread its rain shield across southern CT, RI, and southeastern MA where it will be for a few hours before heading out to sea along with the storm as dry air overtakes the region today. A quick-moving disturbance will bring cloudiness and the threat of a little rain to the region during the first half of Saturday before the remainder of the weekend is dry and cool. The remains of Pacific tropical cyclone Sergio will track through the Great Lakes and drag a cold front this way wit a shower risk Monday before more dry and cool air follows that. Forecast details…
TODAY: Cloudy start with rain south and east of a line from northeastern CT to Boston, moving out from west to east during midday. Clearing west to east this afternoon. Highs 60-67.

SUNDAY: Mostly sunny. Highs 56-62. Wind W up to 10 MPH.
MONDAY: Mostly cloudy. Chance of rain showers in the afternoon. Lows in the 40s. Highs from the upper 50s to lower 60s.
TUESDAY: Partly cloudy to mostly sunny. Lows from the lower to middle 50s. Highs from the upper 50s to lower 60s.

DAYS 6-10 (OCTOBER 17-21)
Quick moving front may produce a rain shower around October 18 otherwise mainly dry weather and below normal temperatures this period.

DAYS 11-15 (OCTOBER 22-26)
Watching for 1 or 2 low pressure systems to impact the region with potential wet weather. May be the type of pattern where a few areas see their first snowflakes as well. Temperatures mostly below normal.

Thursday Forecast

7:35AM

DAYS 1-5 (OCTOBER 11-15)
The back-door front slipped through NH and northeastern MA which sits in the upper 50s to near 60 early this morning but hasn’t made it all the way to the southwest where temps sit in the upper 60s to 70, and it will generally remain like this for a while before that front pushes back to the northeast and the areas damp/cool turn warm/muggy. The foggy/drizzly conditions in the cool air will just be replaced by showers, which are possible anywhere this morning and likely everywhere this afternoon, some of then heavy with even a thunder risk later in the day and in the evening as a stronger cold front pushes in from the northwest, also having picked up some moisture from Hurricane Michael in the process. The remains of that once very powerful storm will be passing south of New England Friday, having lost its tropical characteristics and also become much weaker. It will prolong the rainfall near the South Coast into Friday morning before a drying trend overtakes the region. Much cooler air is on the way for the weekend, but a little wrinkle has appeared in the form of a minor disturbance that will bring cloudiness and the risk of a little rain for a portion of Saturday morning and midday as it moves rapidly west to east. Sunday will be the nicer of the two weekend days. Monday, the weather will head downhill again as the remains of what was once a Pacific tropical system (Sergio) head through the Great Lakes and drag a cold front toward the region. Forecast details…
TODAY: Cloudy. Areas of fog and drizzle with scattered showers morning. Widespread showers and a chance of thunderstorms with possible heavy rainfall afternoon and evening. Damp north and east and muggy south and west morning, muggy all areas afternoon. Highs 67-74. Wind light NE in northeastern MA and southern NH morning, SW up to 10 MPH elsewhere, then SW 10-20 MPH all areas afternoon.
TONIGHT: Cloudy. Numerous showers, some heavy, with a chance of thunderstorms through late evening, then diminishing. Areas of fog. Muggy. Lows 62-67. Wind SW 10-20 MPH shifting to NW overnight.
FRIDAY: Cloudy start with rain likely South Coast and a chance of rain showers elsewhere, then a clearing trend. Drying. Temperatures generally steady in the 60s cooling into the 50s evening.
FRIDAY NIGHT: Mostly clear. Lows 42-48. Wind NW 5-15 MPH.
SATURDAY: Mostly cloudy with a chance of rain morning-midday. Clearing afternoon. Highs 52-58. Wind W 5-15 MPH.
SUNDAY: Mostly sunny. Lows from the middle 30s to lower 40s. Highs from the middle 50s to lower 60s.
MONDAY: Mostly cloudy. Chance of rain showers in the afternoon. Lows in the 40s. Highs from the upper 50s to lower 60s.

DAYS 6-10 (OCTOBER 16-20)
This period will feature mostly dry weather with a possible brief interruption of rain showers around mid period with a reinforcing cold frontal passage. Temperatures generally below seasonal averages.

DAYS 11-15 (OCTOBER 21-25)
There are signals for some unsettled weather both early and again later in the period. Temperatures near to below normal.

Wednesday Forecast

7:33AM

DAYS 1-5 (OCTOBER 10-14)
This update will be short and sweet, as there are basically no changes from yesterday. Today will feel like summer. Tonight, a front will slip down from the Gulf of Maine, bringing a rather quick temperature drop. While this cool air invades the region from northeast to southwest at the surface, the warm and humid air will continue to flow just over that and another cold front will be approaching from the northwest, which itself would bring numerous showers, though these will be somewhat enhanced due to an infusion of moisture from Michael, a land-falling powerful hurricane day on the Florida Panhandle today, weakening to a tropical storm as it passes across Georgia and the Carolinas through Thursday. The front that came through as a back-door cold front will likely return back to the northeast as a warm front yet again Thursday night, just ahead of the cold front from the northwest, which will finally start pushing everything out of here as the center of Michael’s remains passes south of New England on Friday during its transition to an ordinary low pressure area. The passage of this low may be close enough to hold some rainfall in near the South Coast for a portion of Friday morning before a drying trend overtakes the entire region. Friday itself will still be somewhat mild as we’ll have to wait for a secondary cold front to deliver much cooler air by the start of the weekend as it passes by early Saturday. High pressure will be in full control Sunday – a perfect autumn day. Forecast details…
TODAY: Partly to mostly sunny. Humid. Highs 75-83. Wind SW 5-15 MPH with higher gusts.
TONIGHT: Partly cloudy evening. Cloudy with areas of fog, patchy drizzle, and a chance of showers overnight. Humid evening, damp overnight. Lows 55-62. Wind W up to 10 MPH shifting to NE from northeast to southwest.
THURSDAY: Cloudy. Areas of fog and drizzle with scattered to numerous showers morning. Widespread showers and a chance of thunderstorms with possible heavy rainfall afternoon and evening. Damp morning, muggy afternoon. Highs 67-74. Wind light E morning, SW 10-20 MPH afternoon.
THURSDAY NIGHT: Cloudy. Numerous showers, some heavy. Chance of thunderstorms. Areas of fog. Muggy. Lows 62-67. Wind SW 10-20 MPH.
FRIDAY: Cloudy start with rain likely South Coast and a chance of showers elsewhere, then a clearing trend. Lowering humidity. Temperatures generally steady in the 60s cooling into the 50s evening.
SATURDAY: Partly sunny. Lows from the middle to upper 40s. Highs from the middle to upper 50s.
SUNDAY: Mostly sunny. Lows from the middle 30s to lower 40s. Highs from the upper 50s to lower 60s.

DAYS 6-10 (OCTOBER 15-19)
Low pressure that was once Pacific Hurricane Sergio will pass north of the region October 15 bringing a front with rain showers through. Much of the remainder of the period will be dry with below normal temperatures through a reinforcing cold front is due around October 18.

DAYS 11-15 (OCTOBER 20-24)
Trend for this period is mostly dry weather other than a minor rain shower threat from a couple frontal passages, and near to below normal temperatures dominating. May have to watch for the approach of a larger wet weather system by the end of the period.

Tuesday Forecast

7:20AM

DAYS 1-5 (OCTOBER 9-13)
Another warm surge is on the way, coming in behind a warm frontal passage this morning and lasting through Wednesday. But quick changes will follow this as our warm-up is attacked from 2 directions, the first being the friendly warm front which will have turned around and sneaked back as a a back-door cold front that slips in via the Gulf of Maine late Wednesday night into early Thursday, bringing a rather quick temperature drop. While this cool air invades the region from northeast to southwest at the surface, the warm and humid air will continue to flow just over that and another cold front will be approaching from the northwest, which itself would bring numerous showers, though these will be somewhat enhanced due to an infusion of moisture from Michael, a land-falling hurricane Wednesday on the Florida Panhandle, weakening to a tropical storm as it passes across Georgia and the Carolinas through Thursday. The front that came through as a back-door cold front will likely return back to the northeast as a warm front yet again Thursday night, just ahead of the cold front from the northwest, which will finally start pushing everything out of here as the center of Michael’s remains passes south of New England early Friday during its transition to an ordinary low pressure area. The passage of this low may be close enough to hold some rainfall in near the South Coast for a portion of Friday morning before a drying trend overtakes the entire region. Friday itself will still be somewhat mild as we’ll have to wait for a secondary cold front to deliver much cooler air by the start of the weekend as it passes by early Saturday. Forecast details…
TODAY: Mostly cloudy to partly sunny with patchy fog morning. Partly to mostly sunny afternoon. Increasingly humid. Highs 73-79. Wind S to SW 5-15 MPH.
TONIGHT: Partly to mostly cloudy. Patchy fog. Humid. Lows 62-68. Wind SW up to 10 MPH.
WEDNESDAY: Partly to mostly sunny. Humid. Highs 75-83. Wind SW 5-15 MPH with higher gusts.
WEDNESDAY NIGHT: Partly cloudy evening. Cloudy with areas of fog, patchy drizzle, and a chance of showers overnight. Humid evening, damp overnight. Lows 55-62. Wind W up to 10 MPH shifting to NE from northeast to southwest.
THURSDAY: Cloudy. Areas of fog and drizzle with scattered to numerous showers morning. Widespread showers and a chance of thunderstorms with possible heavy rainfall afternoon and evening. Damp morning, muggy afternoon. Highs 67-74. Wind light E morning, SW 10-20 MPH afternoon.
FRIDAY: Cloudy start with rain likely South Coast and a chance of showers elsewhere, then a clearing trend. Lowering humidity. Temperatures generally steady in the 60s cooling into the 50s at night.
SATURDAY: Partly cloudy early then mostly sunny. Lows from the middle to upper 40s. Highs from the middle to upper 50s.

DAYS 6-10 (OCTOBER 14-18)
Chilly and bright start and milder and filtered sun finish to October 14. Moisture from former Pacific Hurricane Sergio, in the form of a low pressure area passing northwest of the region with a trailing cold front, brings a chance of showers sometime during October 15 to early October 16. The remainder of this period looks generally dry with below normal temperatures.

DAYS 11-15 (OCTOBER 19-23)
Trend for this period is mostly dry weather other than a minor rain shower threat from a frontal passage around mid period, and near to below normal temperatures dominating.

Monday Forecast

7:36AM

DAYS 1-5 (OCTOBER 8-12)
We have had plenty of air mass changes lately, and another one occurred Sunday afternoon and evening as a cold front dropped down from the north and cooled the region off again. We’ll remain in that cooler air today before the front goes back to the north as a warm front early Tuesday, bringing one more taste of summer into the region Tuesday and Wednesday. The next weather change will be slightly more dramatic as a stronger cold front approaches from the west Thursday and moisture from Gulf of Mexico TS Michael, forecast to be a hurricane before landfall on the FL Panhandle, gets involved with the front and enhances the rainfall. The actual system should pass just south of the region early Friday, but far enough south to keep its heaviest rain and strongest wind offshore, although a slight shift to the north in that track and things could change. For now will go for a quicker improvement in weather on Friday. Forecast details…
TODAY: Cloudy. Patchy drizzle. Isolated rain showers. Highs 57-63. Wind NE 5-15 MPH.
TONIGHT: Mostly cloudy. Areas of fog. Patchy drizzle. Scattered rain showers. Damp. Lows 50-56 evening, rising slowly overnight. Wind SE under 10 MPH shifting to S.
TUESDAY: Partly sunny. Humid. Highs 68-75. Wind S 5-15 MPH.
TUESDAY NIGHT: Partly cloudy. Patchy fog. Humid. Lows 60-67. Wind SW 5-15 MPH.
WEDNESDAY: Mostly sunny to partly cloudy. Humid. Highs 76-83. Wind SW 10-20 MPH.
THURSDAY: Mostly cloudy. Muggy. Rain showers likely especially afternoon and night with the potential for heavy rainfall. Lows in the 60s. Highs in the 70s.
FRIDAY: Mostly cloudy with a chance of rain especially southeastern areas early, then clouds/sun and breezy. Less humid. Temperatures fall through the 60s.

DAYS 6-10 (OCTOBER 13-17)
October 13-14 weekend looks dry and quite cool, sun/cloud mix with a gusty breeze Saturday, more sun Sunday. Wave of low pressure may bring unsettled weather October 15 before more dry and chilly weather follows this.

DAYS 11-15 (OCTOBER 17-21)
Current indications are for a fairly quiet pattern with mainly dry weather and below to near normal temperatures.

Sunday Forecast

7:14AM

DAYS 1-5 (OCTOBER 7-11)
Milder air has moved in, but a cold front will be dropping southward through the region later in the day, and may trigger a few showers in an otherwise largely rain-free day today. This front, like many others, will be followed by a bubble of high pressure moving east southeastward across southeastern Canada, bringing an onshore flow into the region Monday. The high will then sink to the south southeast and turn the wind more southerly by Tuesday, and then southwesterly by Wednesday, transporting more warm air back into the region. As we get to Thursday, a front will be moving in from the west and at the same time, tropical moisture and possibly the low pressure system itself associated with what is forecast to be TS Michael in the eastern Gulf of Mexico moving into the southeastern US. What isn’t known yet is timing of potential wet weather and magnitude of rainfall, including the level of warmth which will be dependent on cloud cover and rainfall timing. With this still 5 days away, there will be plenty of time to fine-tune it. Forecast details…
TODAY: Mostly cloudy. Patchy very light drizzle early morning. Isolated rain showers afternoon favoring areas near and south of I-90. Humid. Highs 68-75. Wind SW 5-15 MPH shifting to NW from north to south during the afternoon.
TONIGHT: Mostly cloudy. Isolated rain showers. Lows 50-56. Wind NW 5-15 MPH shifting to NE.
MONDAY: Cloudy. Patchy drizzle. Damp. Highs 57-63. Wind NE 5-15 MPH.
MONDAY NIGHT: Mostly cloudy. Areas of fog. Patchy drizzle. Slight chance of a rain shower. Damp. Lows 50-56. Wind SE under 10 MPH.
TUESDAY: Partly sunny. Humid. Highs 68-75. Wind S 5-15 MPH.
WEDNESDAY: Mostly sunny. Humid. Lows from the upper 50s to middle 60s. Highs from the middle 70s to lower 80s.
THURSDAY: Mostly cloudy. Muggy. Rain showers likely especially afternoon and night with the potential for heavy rainfall. Lows in the 60s. Highs in the 70s.

DAYS 6-10 (OCTOBER 12-16)
Drier weather, lowering humidity, but still mild October 12. October 13-14 weekend turns cooler with mostly dry weather expected but will watch a weak low pressure area that should pass to the south of the region. Dry with below normal temperatures and a stronger flow of air from the northwest later in the period.

DAYS 11-15 (OCTOBER 17-21)
May have to watch one area of wet weather to the south around the middle of the period but overall the early idea is for mostly dry weather and temperatures near to below normal for the middle of the month.

Saturday Forecast

10:17AM

DAYS 1-5 (OCTOBER 6-10)
It will be a weekend of variable and often plentiful cloudiness as we’ll be near the border of the cool air that was over the region in force yesterday and much warmer air located to the south. The region will end up on the warmer side of this boundary Sunday and back on the cooler side of it Monday, though neither today nor Monday will be as chilly as the mid to late October feel of yesterday. The threat of any shower activity is pretty minimal with only the risk of an isolated shower passing by any given location during Sunday afternoon. The indecisive boundary will push back to the north Tuesday and introduce much warmer air at that time into mid week. Forecast details…
TODAY: Southeastern MA mostly to partly sunny, elsewhere mostly cloudy to partly sunny. Highs 60-67. Wind light variable.
TONIGHT: Variably cloudy. Lows 50-57. Wind S up to 10 MPH.
SUNDAY: Mostly cloudy. Slight chance of a passing shower afternoon. Highs 68-75. Wind SW 5-15 MPH.
SUNDAY NIGHT: Mostly cloudy. Lows 52-59. Wind SW 5-15 MPH shifting to N.
MONDAY: Mostly cloudy. Highs 60-67. Wind N to NE 5-15 MPH.
TUESDAY: Partly cloudy. Lows from the middle 50s to lower 60s. Highs in the 70s.
WEDNESDAY: Mostly sunny. Lows from the upper 50s to lower 60s. Highs from the middle 70s to lower 80s.

DAYS 6-10 (OCTOBER 11-15)
Many potential factors play into the outlook for this period of time, including the timing of a front from the west early in the period. Right now thinking that October 11 turns out showery but mild and there may be the potential for heavy rainfall involved if tropical moisture from the south gets involved. After that a switch to drier and somewhat cooler weather but another system may try to bring cloudiness or a few showers at some point during the course of the second weekend of the month.

DAYS 11-15 (OCTOBER 16-20)
Saying “I have no solid idea” would be a more confident statement than trying to actually make a forecast here, but I will say that my idea is for a transitional pattern that battles between lingering warmth and increased chances for shots of cool air with at least one opportunity for a widespread wet weather event.

Friday Forecast

7:21AM

DAYS 1-5 (OCTOBER 5-9)
A taste of mid autumn today as a shot of much cooler air from eastern Canada flows across the region but once again by way of the Gulf of Maine, because of the orientation of high pressure causing a northeasterly surface wind instead of a northwesterly one. As we have seen many times, the high sinks to the southeast and it results in a warm up but with some cloudiness at times as we go into the weekend, which includes a Monday holiday for some, although that day will temporarily cool down behind a back-door front and another nose of high pressure from eastern Canada which quickly heads to the southeast as well and yy the time we get to Tuesday next week the region will be back into unseasonably warm air again. Forecast details…
TODAY: Partly to mostly sunny. Highs 57-63. Wind NE 5-15 MPH.
TONIGHT: Mostly clear. Lows 38-45 interior rural and suburban areas, 45-52 elsewhere. Wind light variable.
SATURDAY: Partly sunny. Highs 60-67. Wind light variable.
SATURDAY NIGHT: Variably cloudy. Lows 50-57. Wind S up to 10 MPH.
SUNDAY: Partly sunny. Highs 68-75. Wind SW 5-15 MPH.
MONDAY: Partly cloudy. Lows in the 50s. Highs in the 60s.
TUESDAY: Partly cloudy. Lows from the middle 50s to lower 60s. Highs in the 70s.

DAYS 6-10 (OCTOBER 10-14)
The forecast confidence drops during the course of this period due to a few unknowns, including moisture from a tropical system in the eastern Pacific, which could reach the region by the end of the period. Before that, the same pattern goes on with a warm start, a brief cool-down, then a warm-up again.

DAYS 11-15 (OCTOBER 15-19)
Low confidence forecast. Wet weather threat early in the period may be followed by a significant shot of cool air then a gradual moderation with mostly dry weather.

Thursday Forecast

7:25AM

DAYS 1-5 (OCTOBER 4-8)
The large scale pattern continues to feature a dominant trough in the western US and dominant ridge in the eastern US, which for the East is a generally warm pattern. Also, there has been a lot of early-season cold in central and northern Canada, though this has been generally locked up there because of a west to east flow up there and little chance for any of it to be pulled to the south. This pattern continues through this 5-day forecast period. Today will be one of the warmer days as we get into a southwesterly air flow ahead of a cold front. This front may bring a few showers to the region this evening just prior to or early in the Patriots game in Foxboro. Behind this front comes a brief shot of cool air for Friday, but as many of them before this one, the high pressure are will track north of the region, producing a northeasterly air flow, and then the high will sink to the south as we get into the weekend, resulting in a warming trend again. The boundary that went by late Thursday will be coming back but at this time it may not have enough moisture for any rainfall, just some cloudiness at times. For some, the “weekend” extends through Columbus Day Monday, then it looks like we’ll be back to a northeasterly air flow and a cool-down as the next bubble of high pressure moves across eastern Canada and northern New England.

DAYS 6-10 (OCTOBER 9-13)
Same weather pattern continues for this period with the warm-up cycle October 9-10, then a likely repeat of the pattern yet again.

DAYS 11-15 (OCTOBER 14-18)
Weather pattern may turn a little wetter at mid month and will also have to watch for a potential tropical moisture connection.

Wednesday Forecast

7:33AM

DAYS 1-5 (OCTOBER 3-7)
I was too optimistic with my “partly sunny” for today on yesterday’s forecast. Low level moisture hangs tough and with no strong push of dry air to scour it out we’ll take most of the day to dry the air out even to go from overcast and damp with areas of fog to just mostly cloudy. But at least the heavy rain is gone. So there’s a plus. We do get a very weak high pressure area to move offshore by tomorrow with a warm-up which is still expected, then a cold front to come through with no more than a few showers during the late day and evening hours. A cooler high pressure area will build across eastern Canada and northern New England Friday and Saturday with cooler air here, especially Friday, but as the high sinks to the southeast during the course of the weekend, a warm-up arrives, especially by Sunday. Forecast details…
TODAY: Cloudy and damp with areas of fog morning. Mostly cloudy and drying out afternoon. Highs 62-68. Wind light N.
TONIGHT: Partly cloudy. Patchy fog interior low elevations. Lows 52-58. Wind light variable.
THURSDAY: Partly cloudy. Highs 72-78. Wind SW 10-20 MPH.
THURSDAY NIGHT: Variably cloudy with a shower possible early. Lows 52-58. Wind SW 10-20 MPH shifting to NW.
FRIDAY: Partly cloudy. Highs 60-66. Wind NE 5-15 MPH.
SATURDAY: Mostly sunny. Lows from the upper 40s to middle 50s. Highs in the 60s.
SUNDAY: Mostly sunny. Lows in the 50s. Highs in the 70s.

DAYS 6-10 (OCTOBER 8-12)
Looks like high pressure will be dominant surface and aloft with dry weather and above normal temperatures through the middle of this period then a trough from the west will try to knock the high down and bring some unsettled weather by later in the period.

DAYS 11-15 (OCTOBER 13-17)
A more changeable period of weather is expected as a flatter flow brings a series of low pressure waves across the region west to east. But high pressure will still be off the Atlantic Coast and the tropics may be active again so that may be another thing to keep an eye on toward the middle to end of the period.

Tuesday Forecast

7:37AM

DAYS 1-5 (OCTOBER 2-6)
Not a whole lot of change from yesterday’s post. In the “dank tank” today but with most of the heavier rainfall holding off until late-day and early night as low pressure moves along a nearly stationary boundary over the region. All of it gets pushed away Wednesday as high pressure builds in, resulting in improved weather. Then the high moves offshore resulting in a warm-up for Thursday before a cold front brings in slightly cooler but fair weather for the end of the week. Forecast details…
TODAY: Cloudy. Patchy fog. Areas of drizzle and scattered showers. More numerous showers arriving from the west by late in the day. Highs
58-65 except 65-72 far southern areas. Wind NE to E 5-15 MPH except variable far southern areas.
TONIGHT: Cloudy with numerous showers in the evening, some heavy. Partial clearing overnight. Areas of fog. Lows 53-60. Wind light variable.
WEDNESDAY: Partly sunny. Highs 68-75. Wind W 5-15 MPH.
WEDNESDAY NIGHT: Partly cloudy. Patchy fog interior low elevations. Lows 52-58. Wind light variable.
THURSDAY: Partly cloudy. Chance of showers at night. Highs 72-78. Wind SW 10-20 MPH.
FRIDAY: Partly cloudy. Lows in the 50s. Highs in the 60s.
SATURDAY: Mostly sunny. Lows from the upper 40s to middle 50s. Highs in the 60s.
