11:28AM

DAYS 1-5 (NOVEMBER 12-16)
Discussion…
The air is warming slowly at the surface and aloft and the warming above us creates some clouds that were abundant at dawn but have decreased since with a bit of drying moving in. But eventually these clouds will win out again by tonight and continue to dominate Monday as a disturbances moves through, igniting a new storm offshore. While that storm will not be close enough to impact this area significantly, during the process we may see some patchy light rain/mix and some higher elevation snow but with no impact. A break between systems Tuesday then the next one, in a little more potent form, arrives from the west at midweek.
Forecast details…
TODAY: Partly sunny. Highs 38-44. Wind light W morning, light S afternoon.
TONIGHT: Mostly cloudy. Lows 33-38. Wind light variable.
MONDAY: Cloudy. Chance of light rain at times, may mix with and turn to snow higher elevations north central MA and southwestern NH late. Highs 38-45. Wind NE 5-15 MPH.
TUESDAY: Partly sunny. Lows from the upper 20s to middle 30s. Highs in the 40s.
WEDNESDAY: Mostly cloudy. Chance of light rain late. Lows in the 30s. Highs in the 40s.
THURSDAY: Mostly cloudy with rain showers morning. Partly cloudy afternoon. Breezy. Lows from the upper 30s to middle 40s. Highs from the middle 40s to lower 50s.

DAYS 6-10 (NOVEMBER 17-21)
A dry interlude November 17 before the next storm system arrives to bring wet weather (some interior mix?) on November 18 then departs but leaves wind and cold in its wake for November 19-20 before becoming more tranquil but still quite chilly November 21.

DAYS 11-15 (NOVEMBER 21-25)
A blocking pattern develops with high pressure over Greenland and this forces the jet stream to the south. So far it looks like it will not amplify enough for major storminess during this period but something to watch.

8:18AM

On this Veterans Day I would like to thank all that have served in the armed forces to protect our freedom!

DAYS 1-5 (NOVEMBER 11-15)
Discussion…
Dress for winter temperatures if you are heading out to any Veterans Day ceremonies this morning and early afternoon. The most harsh will be this morning as temperatures climb through the 20s and the wind still remains gusty, but midday and beyond will be less so as we recover into the 30s with less wind. There will be 100% sunshine at least. High pressure moves right overhead tonight and this will prompt temperatures to fall all over again due to radiational cooling. As that happens a slight increase in the moisture in the air will cause frost to form, so anybody heading out to drive early Sunday may have to deal with scraping ice or waiting for the vehicle’s defrost system to melt it. A combination of increasing moisture from the south and an approaching disturbance from the west will increase the cloud cover and moderate the temperature on Sunday. The disturbance, though weak as it approaches and moves through during Monday, will begin to intensify offshore as it moves away, and just enough cold air will be around for some minor snow accumulation in the higher elevations of central MA and southwestern NH by Monday evening. Fair weather is expected Tuesday between this system and the next approaching disturbance which will return more clouds to the region by Wednesday and possibly some light rain by Wednesday night, based on current timing and the thought that it will be a little milder going into the midweek system.
Forecast details…
TODAY: Sunny. Highs 34-42, mildest Cape Cod. Wind NW 10-20 MPH and gusty early, diminishing during the day.
TONIGHT: Partly cloudy. Lows 12-17 interior valleys, 18-25 elsewhere. Wind calm.
SUNDAY: Partly sunny. Highs 38-44. Wind light W morning, light S afternoon.
SUNDAY NIGHT: Mostly cloudy. Lows 33-38. Wind light variable.
MONDAY: Cloudy. Chance of light rain at times, may mix with and turn to snow higher elevations north central MA and southwestern NH late. Highs 38-45. Wind NE 5-15 MPH.
TUESDAY: Partly sunny. Lows from the upper 20s to middle 30s. Highs in the 40s.
WEDNESDAY: Mostly cloudy. Chance of light rain late. Lows in the 30s. Highs in the 40s.

DAYS 6-10 (NOVEMBER 16-20)
Small low pressure system intensifies while departing Thursday November 16 which should turn out dry/breezy/cool. High pressure should bring fair weather Friday November 17 but clouds may be increasing ahead of next low pressure system which brings unsettled weather to start then windy and drying later in the November 18-19 weekend with fair and chilly weather for November 20.

DAYS 11-15 (NOVEMBER 21-25)
A blocking pattern develops with high pressure over Greenland and this forces the jet stream to the south. So far it looks like it will not amplify enough for major storminess during Thanksgiving Week but something to watch.

3:54PM

DAYS 1-5 (NOVEMBER 10-14)
The cold has arrived, and will behave as advertised. There are no major changes to the outlook other than to inform you that the energy for the coming unsettled weather looks like it will keep its focus more to the south and therefore cloudiness will be the dominant feature as opposed to precipitation when we get to early next week. In the mean time, the wind/cold will be the story through Saturday morning, so bundle up for any football games and Veterans Day ceremonies.
THROUGH EVENING: Clear. Temperatures fall from the 30s to the upper 20s. Wind NW 10-20 MPH, higher gusts. Wind chill in the 10s.
OVERNIGHT: Clear. Lows 10-15 except 15-22 urban areas and immediate coast. Growing season ends anywhere it has not up to this point. Wind NW 5-15 MPH, higher gusts. Wind chill near to below 10 at times.
SATURDAY – VETERANS DAY: Sunny. Highs 35-40. Wind NW 5-15 MPH, diminishing.
SATURDAY NIGHT: Clear. Lows 10-15 deepest valleys, 15-23 elsewhere. Wind calm.
SUNDAY: Increasing clouds. Chance of light rain and snow at night. Highs 40-47. Wind light SE.
MONDAY: Cloudy. Slight chance of light rain. Lows from the lower 30s to near 40. Highs from the middle 40s to near 50.
TUESDAY: Mostly sunny. Lows in the 30s. Highs in the 40s.

DAYS 6-10 (NOVEMBER 15-19)
Next system approaches from the west and likely returns clouds to the region and a risk of light mix/rain late November 15 into early November 16 followed by dry weather through November 17. Watching for a possible storm system on the weekend of November 18-19 but low confidence at this time.

DAYS 11-15 (NOVEMBER 20-24)
Thanksgiving week currently looks fairly dry and on the cool to cold side with a northwesterly flow but far too early for too many details.

3:02AM

DAYS 1-5 (NOVEMBER 9-13)
A frosty start will be followed by a decent temperature recovery to over 50 for many areas today. But this brief “warm-up” will be a memory after an arctic cold front comes through the region by early Friday, introducing the coldest air in quite some time to the region, along with wind, during Friday, and continued quite chilly but with less wind Saturday. The next low pressure system approaches later Sunday and brings a risk of wet weather by Monday.
TODAY: Mostly sunny. Highs 50-57. Wind S 5-15 MPH.
TONIGHT: Variably cloudy. A passing rain shower possible overnight. Temperatures fall into the 40s. Wind SW 10-20 MPH.
FRIDAY: Partly cloudy. Slight risk of passing snow showers morning. Temperatures fall into the 30s. Wind W to NW 10-20 MPH, gusting 30-35 MPH. Wind chill temperatures falling into the 20s then the 10s.
SATURDAY: Mostly sunny. Lows in the 20s. Highs from the middle 30s to lower 40s.
SUNDAY: Increasing clouds. Lows from the upper 10s to middle 20s. Highs in the 40s.
MONDAY: Cloudy. Chance of rain. Temperatures steady in the 40s.

DAYS 6-10 (NOVEMBER 14-18)
Watching low pressure which may try to hang close to or just south and east of the region for a portion of this period. Fine line between fair and foul weather so further analysis will be needed to figure out how things run during mid November.

DAYS 11-15 (NOVEMBER 19-23)
The uncertainty of the period preceding this now throws this period into a little uncertainty. Leaning toward fair weather to start, stormy weather to end, but very far away and much to figure out.

7:31AM

DAYS 1-5 (NOVEMBER 8-12)
Wave of low pressure through brought the first snow flakes to parts of the region (mainly north and west of Boston), and rain elsewhere is departing but a northeast wind behind it may hold cloudiness in over southeastern MA much of the day while a clearing trend takes place elsewhere. High pressure moves in tonight which will be clear and cold, ending the growing season in areas it has not ended already, except possibly Cape Cod, but they will not escape a regionwide freeze this coming weekend. Before that happens, we’ll enjoy a fair and slightly milder Thursday before an arctic cold front crosses the region Thursday night and early Friday, opening the door to a taste of winter air. A windy/cold night is in store for any high school football playoff games on Friday night, and a very cold morning can be expected for Veterans Day ceremonies on Saturday.
TODAY: Mostly cloudy early with a bit of drizzle or a passing rain shower southeastern MA. Clouds lingering in southeastern MA much of the day with sun returning elsewhere. Highs 46-53. Wind NE to N 10-20 MPH, diminishing late.
TONIGHT: Clear. Lows 20-26 interior valleys, 27-34 elsewhere. Widespread frost as well as hard freeze in areas under 28. Wind calm.
THURSDAY: Mostly sunny. Highs 50-57. Wind S 5-15 MPH.
THURSDAY NIGHT: Variably cloudy. A passing rain shower possible overnight. Temperatures fall into the 40s. Wind SW 10-20 MPH.
FRIDAY: Partly cloudy. Slight risk of passing snow showers morning. Temperatures fall into the 30s. Wind W to NW 10-20 MPH, gusting 30-35 MPH. Wind chill temperatures falling into the 20s then the 10s.
SATURDAY: Mostly sunny. Lows in the 20s. Highs from the middle 30s to lower 40s.
SUNDAY: Increasing clouds. Lows from the upper 10s to middle 20s. Highs in the 40s.

DAYS 6-10 (NOVEMBER 13-17)
Low pressure moves through the region with a rain risk November 13. Another disturbance may bring unsettled weather during November 15. Otherwise a fair weather interlude November 14 and dry weather returning later in the period. Temperatures variable, near normal overall.

DAYS 11-15 (NOVEMBER 18-22)
Expect a progressive pattern, fairly weak weather systems and changeable temperatures.

3:30PM

DAYS 1-5 (NOVEMBER 7-11)
Sorry for the late update today. There are adjustments and here is the summary. The cold front that went by overnight did not get that far to the south, held up by a wave of low pressure moving along it that sent clouds back into the region today and will send some rain into southern areas this evening before it moves out overnight. This wave moves right along and clearing returns to the region on Wednesday, which will be a cool day. A slight moderation takes places Thursday ahead of an arctic cold front, which will plow through the region Friday morning, delivering the coldest air mass in quite some time to the region during Friday and into Saturday (Veterans Day). A windy/cold night is in store for any high school football playoff games on Friday night, and a very cold morning can be expected for Veterans Day ceremonies on Saturday.
REMAINDER OF TODAY: Overcast. Temperatures in the 40s. Wind light SE to E.
TONIGHT: Overcast. A period of rain likely south of the Mass Pike. A brief period of very light rain possible elsewhere. Lows 35-40. Wind light variable.
WEDNESDAY: Clearing. Highs 46-53. Wind N up to 10 MPH.
WEDNESDAY NIGHT: Clear. Lows 20-26 interior valleys, 27-34 elsewhere. Widespread frost as well as hard freeze in areas under 28. Wind calm.
THURSDAY: Mostly sunny. Highs 50-57. Wind S 5-15 MPH.
FRIDAY: Partly cloudy. Slight risk of passing snow showers morning. Temperatures fall from the 40s through the 30s. Becoming windy.
SATURDAY: Mostly sunny. Lows from the upper 10s to middle 20s. Highs from the middle 30s to lower 40s.

DAYS 6-10 (NOVEMBER 12-16)
A zonal pattern will send 2 disturbances through the region with rain chances, current timing suggesting it as late November 12 to early November 13 and again later November 15. Variable temperatures should average fairly close to normal.

DAYS 11-15 (NOVEMBER 17-21)
The pattern of the previous period should continue through this period as well.

4:53AM

DAYS 1-5 (NOVEMBER 6-10)
One more day of unseasonable warmth before we enter a new pattern, which gets introduced by a strong cold front passing through tonight, preceded by rounds of rain showers, a few of which may be heavy. A little wave on the front may try to hold some cloudiness in the region on Tuesday but otherwise high pressure will build north of the region and provide dry and seasonably chilly air through midweek. A stronger cold front will send an even colder air mass into the region by the end of the week.
TODAY: Partly sunny with a slight risk of isolated to scattered rain showers morning. Mostly cloudy with rain showers likely and a chance of thunderstorms in the afternoon. Highs 65-72. Wind SW 10-20 MPH with higher gusts.
TONIGHT: Mostly cloudy evening with rain showers likely and a slight chance of thunderstorms. Partly cloudy overnight. Lows 45-50. Wind shifting to NW 10-20 MPH with higher gusts.
TUESDAY: Partly sunny. Highs 50-55. Wind N 5-15 MPH.
WEDNESDAY: Mostly sunny. Lows from the middle 30s to lower 40s. Highs from the upper 40s to middle 50s.
THURSDAY: Partly cloudy. Chance of rain showers late evening. Lows in the 30s. Highs from the upper 40s to middle 50s.
FRIDAY: Partly cloudy. Slight risk of isolated snow showers. Windy Lows in the 30s. Highs in the 40s.

DAYS 6-10 (NOVEMBER 11-15)
High pressure moves in November 11 with less wind and dry weather but cold air. A fast-flowing west to east jet stream will bring the next disturbance in during November 12-13 with more unsettled weather. This one has the potential to be a significant rain and possibly a moderate to strong wind event. It may linger into November 14 before dry weather returns through November 15.

DAYS 11-15 (NOVEMBER 16-20)
Passing the middle of the month the overall progressive flow pattern will continue with weaker passing systems and temperature changes.

11:35AM

DAYS 1-5 (NOVEMBER 5-9)
A warm front will pass through the region today and this evening with an overcast sky but very limited rain due to a lack of moisture. Following this will be a cold front which approaches Monday with a warm day ahead of it, and plenty of moisture for wet weather by evening. Seasonably chilly air will arrive Tuesday and last through midweek as a sprawling high pressure area moves in and keeps any additional storminess to the south.
THIS AFTERNOON: Cloudy. Highs 55-60. Wind light SE.
TONIGHT: Cloudy. Scattered light rain. Lows 50-55 evening then warming toward 60 overnight. Wind SE shifting to SW 5-15 MPH.
MONDAY: Partly sunny with a slight risk of isolated rain showers through early afternoon. Mostly cloudy with an increasing chance of rain showers late in the day. Highs 65-72. Wind SW 10-20 MPH with higher gusts.
MONDAY NIGHT: Mostly cloudy evening with rain showers likely and a slight chance of thunderstorms. Partly cloudy overnight. Lows 45-50. Wind shifting to NW 10-20 MPH with higher gusts.
TUESDAY: Partly cloudy. Highs 50-55. Wind N 5-15 MPH.
WEDNESDAY: Mostly sunny. Lows from the middle 30s to lower 40s. Highs from the upper 40s to middle 50s.
THURSDAY: Mostly sunny. Lows in the 30s. Highs from the upper 40s to middle 50s.

DAYS 6-10 (NOVEMBER 10-14)
A strong cold front is expected to move through on November 10 bringing more wind and a shot of colder air into the region into November 11. A fast-flowing west to east jet stream will bring the next disturbance in during November 12-13 with more unsettled weather. This one has the potential to be a significant rain and possibly a moderate to strong wind event. It may linger into November 14.

DAYS 11-15 (NOVEMBER 15-19)
Passing the middle of the month the overall progressive flow pattern will continue with weaker passing systems and temperature changes.

6:56AM

DAYS 1-5 (NOVEMBER 4-8)
High pressure hangs on today with fair weather. A warm front approaches Sunday then passes through at night introducing a shot of very mild air once again for Monday before a stronger cold front brings more seasonable air into the region by Tuesday and Wednesday.
TODAY: Sun and high clouds. Highs 53-58. Wind N to NE 5-15 MPH.
TONIGHT: Thickening clouds. Lows 38-45. Wind E 5-15 MPH.
SUNDAY: Cloudy. Chance of light rain. Highs 48-55. Wind E to SE 5-15 MPH.
SUNDAY NIGHT: Mostly cloudy. Temperatures steady or slowly rising. Wind S to SW 5-15 MPH.
MONDAY: Partly sunny morning. Mostly cloudy with increasing chance of showers and a slight risk of thunderstorms afternoon and evening. Highs 65-72. Wind SW 10-20 MPH with higher gusts.
TUESDAY: Partly cloudy. Lows in the 30s. Highs in the 50s.
WEDNESDAY: Mostly sunny. Lows in the 30s. Highs in the 50s.

DAYS 6-10 (NOVEMBER 9-13)
Fair and slightly milder November 9 then an arctic cold front will bring a shot of very chilly air to the region along with gusty wind November 10. High pressure brings fair weather for Veterans Day November 11 but with a very cold start. Unsettled weather returns as low pressure approaches then moves through from west to east during November 12-13.

DAYS 11-15 (NOVEMBER 14-18)
A fairly zonal (west to east) flow will bring cooler weather to start then a moderating trend with mainly dry weather expected.

9:44AM

DAYS 1-5 (NOVEMBER 3-7)
A cold front will cross the region during today and will be proceeded by very mild air and accompanied by a broken to solid line of showers. High pressure slides west to east across southeastern Canada over the weekend. A north to northeast flow of air will bring fair weather on Saturday and as the wind turns east to southeast Sunday it will become at least cloudy and possibly wet at times. The flow will continue to veer toward the south and southwest by Monday ahead of a cold front so it will warm up again that day but still be on the unsettled side. By Tuesday we should be back to dry but this time much cooler weather.
TODAY: Mostly cloudy through mid afternoon north and west and late afternoon south and east with a band of rain showers likely moving northwest to southeast across the region during the afternoon, then a clearing trend especially north and west late. Highs 67-74. Wind SW 10-20 MPH, a few higher gusts, shifting to W late.
TONIGHT: Clearing. Lows 36-44. Wind NW 5-15 MPH.
SATURDAY: Mostly sunny. Highs 53-58. Wind N to NE 5-15 MPH.
SATURDAY NIGHT: Increasing clouds. Lows 38-45. Wind E 5-15 MPH.
SUNDAY: Cloudy. Chance of light rain. Highs 48-55. Wind E to SE 5-15 MPH.
MONDAY: Mostly cloudy. Chance of showers. Lows in the 40s. Highs in the 60s.
TUESDAY: Partly cloudy. Lows in the 30s. Highs in the 50s.

DAYS 6-10 (NOVEMBER 8-12)
A wave of low pressure should stay south of the region early November 8 otherwise dry and cool, then dry and moderating November 9, a chance of rain or showers with a cold front about November 10, briefly fair and cooler November 11 then unsettled weather returns to end the period as a fairly fast flow dominates.

DAYS 11-15 (NOVEMBER 13-17)
Unsettled weather early in the period followed by fair and cooler to colder as a flat ridge in the Southeast backs up a bit to the Midwest and allows a dip in the jet stream over the Northeast.

3:33PM

DAYS 1-5 (NOVEMBER 2-6)
Simple pattern = simple forecast. Warm front has gone by today and has brought lots of clouds but mild air. Cold front will cross the region during Friday and will be proceeded by very mild air and accompanied by a broken to solid line of showers. High pressure slides west to east across southeastern Canada over the weekend. A north to northeast flow of air will bring fair weather on Saturday and as the wind turns east to southeast Sunday it will become at least cloudy and possibly wet at times. The flow will continue to veer toward the south and southwest by Monday ahead of a cold front so it will warm up again that day but still be on the unsettled side.
REMAINDER OF TODAY: Lots of clouds / partial sun. Highs 65-72. Wind S 5-15 MPH.
TONIGHT: Mostly cloudy. Lows 53-58. Wind S to SW 5-15 MPH.
FRIDAY: Mostly cloudy through mid afternoon north and west and late afternoon south and east with a band of rain showers likely moving northwest to southeast across the region during the afternoon, then a clearing trend especially north and west late. Highs 67-74. Wind SW 10-20 MPH, a few higher gusts, shifting to W late.
FRIDAY NIGHT: Clearing. Lows 36-44. Wind NW 5-15 MPH.
SATURDAY: Mostly sunny. Highs 53-58. Wind N to NE 5-15 MPH.
SATURDAY NIGHT: Increasing clouds. Lows 38-45. Wind E 5-15 MPH.
SUNDAY: Cloudy. Chance of light rain. Highs 48-55. Wind E to SE 5-15 MPH.
MONDAY: Mostly cloudy. Chance of showers. Lows in the 40s. Highs in the 60s.

DAYS 6-10 (NOVEMBER 7-11)
Cold front sweeps through early November 7 with a rain shower risk followed by drying then fair and cooler through November 8, warming somewhat November 9 and 10 with a rain shower risk followed by cooler again November 11.

DAYS 11-15 (NOVEMBER 12-16)
Unsettled weather early in the period followed by fair and cooler to colder as a flat ridge in the Southeast backs up a bit to the Midwest and allows a dip in the jet stream over the Northeast.

2:33PM

DAYS 1-5 (NOVEMBER 1-5)
November is here and it follows Boston’s second warmest October on record (by 0.1 degree F). October 1947 retrains the first place ranking. So how do the first days of the new month look? As one would expect, there will be changes from day to day, but nothing outrageous. High pressure which was overhead last night making for areas of frost this morning is slipping away now. A warm front will then approach and pass through on Thursday with more cloudiness although most rain will remain west and north of the forecast area. A cold front will follow this later Friday and will be more notable for its being preceded by very mild air and followed by a weekend chill. At this point, Saturday looks like the weekend pick with fair weather as high pressure noses in from the north, but this high will slide east far enough to bring an onshore wind at the same time a weak disturbance moves in on Sunday, which will turn less favorable.
THIS AFTERNOON: Mostly cloudy. Highs 48-53 interior higher elevations, 53-58 elsewhere. Wind light variable.
TONIGHT: Cloudy. Slight chance of light rain mainly north and west of Boston. Lows 43-48. Wind light SE.
THURSDAY: Mostly cloudy. Slight chance of light rain through early afternoon mainly north and west of Boston. Highs 63-68 occurring late in the day. Wind light SE shifting to SW and increasing to 5-15 MPH.
THURSDAY NIGHT: Variably cloudy. Lows 53-58. Wind SW 5-15 MPH.
FRIDAY: Partly sunny. Slight chance of passing rain showers. Highs 63-68 South Coast, 68-73 elsewhere. Wind SW 10-20 MPH.
SATURDAY: Partly cloudy. Lows in the 40s. Highs in the 50s.
SUNDAY: Mostly cloudy. Chance of light rain. Lows in the 30s. Highs from the upper 40s to middle 50s.

DAYS 6-10 (NOVEMBER 6-10)
Milder November 6, possible rain showers. Additional rain showers followed by clearing and cooler November 7. Fair November 8-10 dominated by high pressure.

DAYS 11-15 (NOVEMBER 11-15)
Overall pattern should be progressive with a couple chilly shots of air during this period.

3:59AM

DAYS 1-5 (OCTOBER 31-NOVEMBER 4)
Since yesterday’s update was at the end of the day and today’s is early, there has not really been any change in the outlook. The westerly wind relaxes today and calms by tonight as high pressure moves in. A warm front passes by the region Thursday followed by a cold front later Friday. Not a lot of weather associated with these – mainly just temperature changes with a brief warm up then a shot of chill by Saturday.
TODAY: Sunny. Highs 56-62. Wind W 5-15 MPH, higher gusts.
THIS EVENING (HALLOWEEN): Clear. Temperatures cool into 40s. Diminishing W wind.
TONIGHT: Mostly clear. Areas of frost. Lows 28-35 and even colder in some deeper valleys. Wind calm.
WEDNESDAY: Sunshine and high clouds. Highs 55-61. Wind light variable to SE.
THURSDAY: Mostly cloudy. Slight chance of light rain. Lows in the 40s. Highs from the middle 50s to lower 60s.
FRIDAY: Partly sunny. Slight chance of a rain shower. Lows from the middle 40s to lower 50s. Highs from the lower 60s to near 70.
SATURDAY: Mostly sunny. Lows in the 40s. Highs in the 50s.

DAYS 6-10 (NOVEMBER 5-9)
A fast-flowing jet stream will bring frequent changes but no major storms. Look for a frosty start November 5 then clouding up with some unsettled weather into November 7 which will be milder. Uncertain but leaning toward fair and chilly November 8-9.

DAYS 11-15 (NOVEMBER 10-14)
Similar pattern to the previous period expected but impossible to time systems and air mass changes at this point.

5:47PM

DAYS 1-5 (OCTOBER 30-NOVEMBER 3)
As the region recovers from a powerful autumn storm that caused 1 to 4 inches of rain and significant wind damage as well as numerous power outages, we enter a more tranquil pattern as October ends and November begins. Behind the storm came some moderate and gusty winds from the west today which will still continue to blow tonight but gradually diminish during Tuesday, so that be Halloween Night all is fair and tranquil, and because high pressure moves overhead the first of November on Wednesday will start fair and frosty in many areas. A few changes follow, with a warm front bringing a slight chance of light rain Thursday and a cold front bringing a risk of a shower Friday
EVENING: Clear. Temperatures cool through 50s. Wind W 15-25 MPH, higher gusts.
OVERNIGHT: Clear. Lows 38-45. Wind W 10-20 MPH, higher gusts.
TUESDAY: Sunny. Highs 56-62. Wind W 5-15 MPH, higher gusts.
TUESDAY EVENING (HALLOWEEN): Clear. Temperatures cool into 40s. Diminishing W wind.
TUESDAY LATE-NIGHT: Mostly clear. Areas of frost. Lows 28-35 and even colder in some deeper valleys. Wind calm.
WEDNESDAY: Sunshine and high clouds. Highs 55-61. Wind light variable to SE.
THURSDAY: Mostly cloudy. Slight chance of light rain. Lows in the 40s. Highs from the middle 50s to lower 60s.
FRIDAY: Partly sunny. Slight chance of a rain shower. Lows from the middle 40s to lower 50s. Highs from the lower 60s to near 70.

DAYS 6-10 (NOVEMBER 4-8)
A fast-flowing jet stream will bring frequent changes but no major storms. Look for fair/cooler November 4, unsettled weather starting cool and turning milder November 5 into 7 then turning cooler and drier later November 7 through November 8.

DAYS 11-15 (NOVEMBER 9-13)
Similar pattern to the previous period expected but impossible to time systems and air mass changes at this point.

4:00AM

DAYS 1-5 (OCTOBER 29-NOVEMBER 2)
Not a lot of change to the coming event. A front sits oriented basically north-south over the region. Low pressure forms on it and intensifies while moving up the front and across southern New England tonight. All the while TS Philippe moves rapidly north northeastward in the warm/moist southerly flow ahead of the front and its moisture becomes involved in the developing low with its circulation eventually being absorbed by it as it goes by as a transitioning, very small system, passing southeast to east of New England during this process. This system is going to have some significant variability with its wind strength and its rain amounts. There will probably be a ribbon of rain that is oriented south-north somewhere in eastern areas that as higher than most other locations. So while I am expecting a general 1-3 inches of rain, lean toward the higher amounts only where this ribbon of heavier rain exists. Behind this system expect one more push of showers with upper level energy Monday before a drying west wind overtakes the region and continues into Tuesday before diminishing. As November gets underway, we’ll transition from a chilly and tranquil start to the new month Wednesday to a milder and unsettled Thursday as a warm front moves in.
TODAY: Mostly cloudy.
Passing showers through midday then isolated showers east and scattered showers west after 1PM. Highs 60-67. Wind S to SE 5-15 MPH, higher gusts by late in the day.
TONIGHT: Overcast with moderate to heavy rain arriving evening then becoming more occasional interior while likely lasting longer in a heavier band over some eastern areas overnight. Thunderstorms possible. Local flooding, especially on streets and in parking lots with leaf-clogged storm drains. Leaves on roads will make them slippery as well. Lows 53-60. Wind SE 15-25 MPH with gusts 35-50 MPH central MA and southwestern NH, and 25-35 MPH with gusts 45-60 MPH elsewhere. There may be pockets of even stronger wind gusts especially where heaviest rain occurs.
MONDAY: Mostly cloudy with passing rain showers morning and midday, some of which can still be heavy and may contain thunder. Partly sunny remainder of day. Highs 60-67. Wind SW shifting to W 15-25 MPH gusting 35-45 MPH, especially in the afternoon.
TUESDAY: Mostly sunny. Lows in the 30s. Highs in the 50s. Evening temperatures in the 40s. Breezy during the day, less wind evening.
WEDNESDAY: Partly sunny. Lows in the 30s. Highs in the 50s.
THURSDAY: Mostly cloudy. Slight chance of light rain favoring northern MA and southern NH. Lows in the 40s. Highs in the 60s.

DAYS 6-10 (NOVEMBER 3-7)
Current timing suggests a cold front crossing the region with a chance of showers November 3, high pressure settling in with fair and cooler weather November 4 and possibly into November 5 before warm air attempts a comeback later November 5 or November 6 with more cloudiness and possible wet weather. Another cold front approaches by the end of the period and may bring rain showers with mild air ahead of it.

DAYS 11-15 (NOVEMBER 8-12)
The upper level pattern will feature a flat ridge in the US Southeast with a trough over the West. For New England this means a largely west southwest flow, airmass changes but a milder than normal pattern overall. For details we may be cooler early in the period, mild and somewhat unsettled later in the period.
