DAYS 1-5 (DECEMBER 6-10)

Two days of cold will be followed by a warm up Friday through the weekend. A short-duration snow shower event this morning will be focused in eastern MA and parts of southeastern NH, and into RI as well. This will be the result of a northeasterly air flow at the surface, an inverted trough off low pressure well to our southeast, and a weak disturbance passing through above us. This afternoon, we’ll be in a drier northwesterly air flow which will then last through Thursday, as a north-south elongated high pressure area approaches from the west. A weak warm front will pass by uneventfully Thursday night, and as high pressure slides offshore we’ll start a warm-up on Friday which will last through the weekend. Fair weather will be with us Friday and Saturday. A vigorous trough and frontal system trailing a low set to pass to our north will approach later Sunday. We’ll see the wind pick up ahead of this, and a period of strong wind and heavy rain / possible thunder is anticipated as the front crosses the region during Sunday night. More detail can be given for that event as we get closer to its occurrence.

TODAY: Cloudy this morning with snow showers likely from the I-95 belt eastward and a chance of a few snow showers to the west. Snowfall accumulation generally traces / under 1 inch, but 1-2 inches possible on unpaved surfaces just inland mainly Plymouth County MA. Breaking clouds / partial sun this afternoon. Highs 33-40. Wind NE up to 10 MPH shifting to NW.

TONIGHT: Clearing. Lows 20-27. Wind NW up to 10 MPH.

THURSDAY: Mostly sunny. Highs 32-39. Wind NW to variable up to 10 MPH.

THURSDAY NIGHT: Variably cloudy. Lows 20-27. Wind variable under 10 MPH.

FRIDAY: Partly cloudy. Highs 38-45. Wind SW up to 10 MPH.

FRIDAY NIGHT: Partly cloudy. Lows 28-35. Wind SW up to 10 MPH.

SATURDAY: Partly sunny. Highs 43-50. Wind SW 5-15 MPH.

SATURDAY NIGHT: Mostly cloudy. Lows 35-42. Wind S 5-15 MPH.

SUNDAY: Mostly cloudy. Chance of a few rain showers. Heavier rain and possible thunder at night. Highs 55-62. Wind S 10-20 MPH, higher gusts.

DAYS 6-10 (DECEMBER 11-15)

Breezy, dry December 11. Watch for a minor system to bring clouds / light precipitation around the middle of next week but no major storminess indicated. Temperatures variable, averaging near to above normal.

DAYS 11-15 (DECEMBER 16-20)

One or two low pressure systems bring temperature swings and mostly minor precipitation threats with no major storms indicated during this period. Temperatures near to above normal.

DAYS 1-5 (DECEMBER 5-9)

We will be in a chilly northerly air flow during the next three days between high pressure to the west and low pressure well to our southeast. An inverted trough from the low will be nearby later today through early Wednesday, and this, combined with a surface wind that turns northeast and another upper disturbance moving through the region will cause some snow shower activity from tonight into Wednesday morning. This activity will favor the region from the NH Seacoast through eastern and southeastern MA. Some areas will see a minor snowfall accumulation. This event won’t cause many problems, but it can result in temporarily slick conditions on untreated surfaces early Wednesday morning, and again Wednesday evening / night when any meltwater re-freezes. High pressure edges closer to bring dry weather and more sun Thursday, which will also be the coldest day of this 5-day period. Clouds move through Thursday night – an indication of warmer air arriving aloft. At the surface, we’ll see a temperature rebound begin Friday and continue Saturday as the high pressure area slides off to the east and a southwesterly air flow develops. We’ll continue to see dry weather during this late-week period.

TODAY: Partly sunny. Highs 36-43. Wind N up to 10 MPH.

TONIGHT: Cloudy. Snow showers develop, except some mix/rain showers immediate coast / Cape Cod. Snow accumulation less than 1 inch possibly 1-2 inches in a band or two just inland from the MA South Shore (Plymouth / Bristol Counties). Lows 26-33. Wind NE 5-15 MPH.

WEDNESDAY: Mostly cloudy with a chance of snow showers early, then partial sunshine. Highs 33-40. Wind NE to N up to 10 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 21-28. Wind NW up to 10 MPH.

THURSDAY: Mostly sunny. Highs 32-39. Wind NW to variable up to 10 MPH.

THURSDAY NIGHT: Variably cloudy. Lows 20-27. Wind variable under 10 MPH.

FRIDAY: Partly cloudy. Highs 38-45. Wind SW up to 10 MPH.

FRIDAY NIGHT: Partly cloudy. Lows 28-35. Wind SW up to 10 MPH.

SATURDAY: Partly sunny. Highs 43-50. Wind SW 5-15 MPH.

DAYS 6-10 (DECEMBER 10-14)

A shot of warm air, lots of wind, and a band of rain moving through during December 10 (timing / details to be refined, but leaning toward evening for the best rain chance). Windy, dry, cold air returns December 11. Watch for a minor system to bring clouds / light snowfall/mix toward the middle of next week but no major storminess indicated.

DAYS 11-15 (DECEMBER 15-19)

One or two low pressure systems bring temperature swings and mostly minor precipitation threats with no major storms indicated during this period.

DAYS 1-5 (DECEMBER 4-8)

Some temperature and weather variety this week, as one would expect for this time of year, but nothing overly extreme is in our pipeline through Friday. After a rainy Sunday across much of the region (some snow/mix for a while in southern NH), we see that low pressure system exiting early today. Behind this, drier air arrives today, but clouds will be slow to break. Some partial sun arrives but also we keep the chance of a few rain showers around until mid day as a final disturbance crosses the region. Chilly air starts to move in tonight and will be with us Tuesday through the middle of the week. While a weak high pressure area keeps us dry during the day Tuesday, a low pressure area will be taking shape well offshore to our southeast, but an extension of this low pressure in the form of a trough will reach back toward New England, and another disturbance moving in from the west will help enhance that, while surface winds turn northeast Tuesday night into Wednesday. This is a recipe for some precipitation, and with cold air in place, we have a shot at a bout of snow showers Tuesday night and early Wednesday – enough for some minor accumulation, favoring eastern portions of the region. Marginal coastal temperatures mean that the precipitation can fall as a mix or even rain showers there, especially over Cape Cod, but eventually enough cold should be in place to overcome that. This is not going to be a major or long lasting event though, and it’s out of here during the day Wednesday, with dry weather returning, along with cold temperatures through Thursday. As high pressure builds across the region Thursday then off to the east Friday, we’ll see milder air arrive to end this work week.

TODAY: Mostly cloudy through midday with a passing rain shower possible. Cloud/sun mix thereafter. Highs 45-52. Wind NW up to 10 MPH.

TONIGHT: Variably cloudy. Lows 30-37. Wind N up to 10 MPH.

TUESDAY: Partly sunny. Highs 36-43. Wind N up to 10 MPH.

TUESDAY NIGHT: Cloudy. Snow showers develop, except some mix/rain showers immediate coast / Cape Cod. Snow accumulation less than 1 inch. Lows 26-33. Wind NE 5-15 MPH.

WEDNESDAY: Mostly cloudy with a chance of snow showers early, then partial sunshine. Highs 33-40. Wind NE to N up to 10 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 21-28. Wind NW up to 10 MPH.

THURSDAY: Mostly sunny. Highs 32-39. Wind NW to variable up to 10 MPH.

THURSDAY NIGHT: Mostly clear. Lows 18-25. Wind variable under 10 MPH.

FRIDAY: Partly cloudy. Highs 38-45. Wind SW up to 10 MPH.

DAYS 6-10 (DECEMBER 9-13)

A warm-up for next weekend with a fair weather beginning, may end windy and wet as a cold front approaches – still have to refine the timing. Return to colder weather with wind included during December 11. Temperatures return to normal, fair then unsettled weather chance by the end of the period.

DAYS 11-15 (DECEMBER 14-18)

One or two low pressure systems bring temperature swings and mostly minor precipitation threats with no major storms indicated at mid month.

DAYS 1-5 (DECEMBER 3-7)

Low pressure brings rainy weather to our region today into tonight before it tapers off. The low will be passing by just south of our region and there is just enough cold air in place so that some mixed or briefly frozen precipitation can occur early and late in the event in the higher elevations from north central MA to especially southwestern NH. Mostly dry weather and chill-off takes places from early to mid week, and with an upper level trough in place and a couple disturbances moving through it, we need to watch for a couple episodes of rain and snow showers. More important storminess will evolve well to the south and southeast and stay at sea. Once we get to Thursday, a narrowing ridge of high pressure will be over the region and a warm front approaching from the west will spread some clouds back our way.

TODAY: Overcast. Areas of fog. Periods of rain, may be mixed with snow and/or sleet for a while in higher elevations of southwestern NH and north central MA. Highs 42-49. Wind NE 5-15 MPH.

TONIGHT: Cloudy. Rain likely in the evening, tapering off overnight, and may end as some sleet and/or snow in higher elevations of southwestern NH and north central MA. Lows 32-39. Wind N 5-15 MPH, higher gusts.

MONDAY: Mostly cloudy. Early-day rain showers possible eastern coastal areas. Highs 40-47 by midday, cooling into the 30s during the afternoon. Wind N 10-20 MPH.

MONDAY NIGHT: Partly cloudy. Lows 30-37. Wind N 5-15 MPH, higher gusts.

TUESDAY: Partly cloudy. A passing light shower of rain and/or snow possible. Highs 37-44. Wind NW 5-15 MPH, higher gusts possible.

TUESDAY NIGHT: Variably cloudy. Possible snow showers, favoring eastern areas. Lows 23-30. Wind NW-N 5-15 MPH.

WEDNESDAY: Partly sunny. A passing light shower of rain and/or snow possible. Highs 36-43. Wind N 5-15 MPH, higher gusts possible.

WEDNESDAY NIGHT: Partly cloudy. Lows 21-28. Wind NW up to 10 MPH.

THURSDAY: Sunshine then clouds return later. Highs 37-44. Wind variable up to 10 MPH.

DAYS 6-10 (DECEMBER 8-12)

A little uncertain on timing but next significant trough is probably going to feature low pressure tracking west and north of our region with milder air ahead of it and rain favored over any frozen precip around mid period (December 10-11 window). Turns a little colder later in the period behind that system.

DAYS 11-15 (DECEMBER 13-17)

No major storms and no major temperature swings currently indicated for mid month.

Post navigation

DAYS 1-5 (DECEMBER 2-6)

The first weekend of December will feature little sun, limited to areas mainly south of I-90 today, otherwise we’re looking at a generally overcast sky. While today will be rain-free in most of the region with just a chance of a few showers near a frontal boundary in southern NH and far northern MA, Sunday will end up much wetter as a low pressure area approaches. Also, the frontal boundary being to the north today allows mild air in, but this boundary sinks to the south tonight through Sunday before hanging out near or off the South Coast, bringing chilly air into the region. The wet weather hangs around Sunday night but pulls out of the region early Monday. If there is any frozen precipitation associated with this upcoming event, it will be confined to high elevations of southwestern NH and possibly north central MA at the onset and ending of the precipitation. The balance of Monday through Wednesday will be generally dry and on the chilly side, but not too cold. There may be a passing shower of rain and/or snow a couple times with weak upper level low pressure over the region. Additional storminess toward midweek will evolve well offshore to the southeast of New England as the set-up doesn’t really allow it to be closer.

TODAY: Areas of fog early. Mainly cloudy – partial sun most possible I-90 southward through midday. A few rain showers possible near MA/NH border. Highs 48-55. Wind W up to 10 MPH.

TONIGHT: Cloudy. Lows 35-42. Wind N up to 10 MPH.

SUNDAY: Cloudy. Rain becomes more likely from southwest to northeast during the course of the day, but may start as a frozen mix in higher elevations of southwestern NH and north central MA. Highs 42-49. Wind NE 5-15 MPH.

SUNDAY NIGHT: Cloudy. Rain likely. Areas of fog. Lows 35-42. Wind NE 5-15 MPH.

MONDAY: Cloudy start with rain ending, possibly as a frozen mix in higher elevations of southwestern NH and north central MA. Highs 40-47 by midday, cooling into the 30s during the afternoon. Wind N 10-20 MPH.

MONDAY NIGHT: Clearing. Lows 30-37. Wind N 5-15 MPH, higher gusts.

TUESDAY: Partly cloudy. A passing light shower of rain and/or snow possible. Highs 37-44. Wind NW 5-15 MPH, higher gusts possible.

TUESDAY NIGHT: Partly cloudy. Lows 23-30. Wind NNW 5-15 MPH.

WEDNESDAY: Partly sunny. A passing light shower of rain and/or snow possible. Highs 36-43. Wind N 5-15 MPH, higher gusts possible.

DAYS 6-10 (DECEMBER 7-11)

Small, fast-moving low pressure brings minor precipitation threat in the late December 7 to late December 8 window and the next low has a higher chance of heading for the Great Lakes, allowing us to turn milder late period. Otherwise this pattern is mainly dry with no major temp extremes.

DAYS 11-15 (DECEMBER 12-16)

Watching for a storm system early in the period, favoring rain over frozen stuff, then a return to dry weather. Temperatures near to above normal.

DAYS 1-5 (DECEMBER 1-5)

We’re going to see an unsettled pattern open the month of December. Despite that, we start today with sun before clouds roll in ahead of a warm front and a weak low pressure wave. This gives us a shot of light rainfall in the region from around sunset to around midnight, and the frontal boundary lifts northward and then hangs there for several hours Saturday. As a result, we have a milder couple days to start the final month of 2023. Some sunshine may even return to at least areas from the South Coast to the I-90 belt for a while Saturday – a more optimistic forecast than I had on my last update. And it also looks like a rain-free day other than the chance of a brief rain shower passing through north central MA and southwestern NH. The frontal boundary will begin to slip back to the south later Saturday, and by Sunday, it’ll sit just to our south again, and we’ll be back in chilly air under a heavier overcast. A low pressure wave with more moisture will then approach and rain will overspread the region from southwest to northeast during Sunday afternoon and especially Sunday night. There may be just enough cold in place for this to begin as a little bit of frozen/mixed precipitation in the higher terrain of southwestern NH and north central MA, but it will fall mainly as rain, before tapering off early Monday, maybe again as a little mix or wet snow in the aforementioned locations. In general, Monday’s’ weather trend will be for drying, with an increasing breeze and chilly air as clouds start to break. Expect dry weather other than a slight chance of a passing snow flurry, and a chilly breeze on Tuesday, as we’ll be in a northerly air flow between low pressure to the east and high pressure to the west of our region.

TODAY: Sun gives way to clouds. Light rain west of Metro Boston late-day. Highs 46-53. Wind S 5-15 MPH.

TONIGHT: Cloudy. Light rain evening. Patchy fog overnight. Lows 38-45. Wind SW up to 10 MPH.

SATURDAY: Areas of fog early. Cloud/sun mix with most sun I-90 south until midday, then clouds dominant later. A possible brief rain shower north central MA to southwestern NH. Highs 48-55. Wind W up to 10 MPH.

SATURDAY NIGHT: Cloudy. Lows 35-42. Wind N up to 10 MPH.

SUNDAY: Cloudy. Rain becomes more likely from southwest to northeast during the course of the day, but may start as a frozen mix in higher elevations of southwestern NH and north central MA. Highs 42-49. Wind NE 5-15 MPH.

SUNDAY NIGHT: Cloudy. Rain likely. Areas of fog. Lows 35-42. Wind NE 5-15 MPH.

MONDAY: Cloudy start with rain ending, possibly as a frozen mix in higher elevations of southwestern NH and north central MA. Highs 40-47 by midday, cooling into the 30s during the afternoon. Wind N 10-20 MPH.

MONDAY NIGHT: Clearing. Lows 23-30. Wind N 5-15 MPH, higher gusts.

TUESDAY: Partly cloudy. A passing snow flurry possible. Highs 33-40. Wind NW 10-20 MPH, higher gusts.

DAYS 6-10 (DECEMBER 6-10)

Chilly northerly air flow but dry weather December 6. A small and fast-moving low may bring brief precipitation episodes late December 7 to early December 8 with generally dry weather to follow. Temperatures variable during mid to late period but averaging close to normal.

DAYS 11-15 (DECEMBER 11-15)

A fairly quick-moving west to east flow pattern is anticipated at mid month. Active in terms of having a couple of passing low pressure systems but no major storms are indicated, nor are major temperatures swings with near to slightly above normal temperatures despite some variability.

DAYS 1-5 (NOVEMBER 30 – DECEMBER 4)

High pressure to our south will provide a fair, slightly milder day to end November. The early days of December hold some unsettled weather for us. The precise details of how it plays out are still coming into focus but the basic idea is this. A warm front lifts northward into the region on Friday with a shot of light rainfall arriving late in the day end moving out late at night. The boundary I called a warm front initially will sag back to the south as a cold front, eventually to become quasi-stationary during the weekend just to our south. Clouds dominate most of the weekend, but rainfall will be limited, with perhaps a shot of it early Sunday from a weak low pressure wave moving along the frontal boundary, and a more widespread rain arriving Sunday night into Monday with a slightly stronger low moving along the boundary. Currently there is inconsistency from run to run with any single model and non-consensus between different models regarding the play-out of this portion of the unsettled weather event. My leaning based on the meteorology of the situation is for a low pressure wave that moves right across southeastern New England and air too mild to support much in the way of frozen precipitation, hence my forecast wording of “rain”. I’ll watch for colder air to become involved in a substantial enough way to potentially allow the system to end as a mix or some frozen stuff, particularly north and west of Boston, but that’s more detail than I want to dive into in a situation far too uncertain for a day 5 forecast. As always, fine-tuning takes place in the next few forecasts posts. You can also check out comments I post for new insight on the potential.

TODAY: Sun/cloud mix southern NH and northern MA with full sun elsewhere this morning. Sunshine and a few high clouds this afternoon. Highs 40-47. Wind WSW 5-15 MPH, a few gusts around 20 MPH South Coast.

TONIGHT: Mostly clear. Lows 30-37. Wind SW up to 10 MPH.

FRIDAY: Clouding up. Late-day light rain. Highs 46-51. Wind S 5-15 MPH.

FRIDAY NIGHT: Cloudy. Light rain evening. Patchy fog overnight. Lows 36-41. Wind variable up to 10 MPH.

SATURDAY: Cloudy. Foggy areas early. Highs 42-49. Wind N up to 10 MPH.

SATURDAY NIGHT: Cloudy. Chance of light rain overnight. Lows 35-42. Wind N-NE up to 10 MPH.

SUNDAY: Cloudy. Chance of light rain early. Rain likely late in the day. Highs 42-49. Wind NE 5-15 MPH.

SUNDAY NIGHT: Cloudy. Rain likely. Areas of fog. Lows 35-42. Wind NE 5-15 MPH.

MONDAY: Cloudy. Rain likely in the morning, ending during the afternoon. Highs 42-49 early, may fall into the 30s before day’s end. Wind N 10-20 MPH, potential for higher gusts.

DAYS 6-10 (DECEMBER 5-9)

Blocking pattern evolves to put most low pressure far enough south to keep us mainly dry with just an upper trough potentially bringing a few rain and/or snow showers into the middle of this week, followed by a fair weather trend as high pressure takes over. Temperatures generally close to normal.

DAYS 11-15 (DECEMBER 10-14)

Into mid December we go with a pattern that features a loss of blocking, a return to more zonal flow, more active weather but not seeing “medium-range-reliable” signals for major storms or major temperature swings during this particular period.

DAYS 1-5 (NOVEMBER 29 – DECEMBER 3)

Dry weather and a moderating temperature trend is ours for this midweek period as high pressure sprawled to our south moves eastward and gradually turns our wind from west to southwest. An easing of the gradient between this high and low pressure to our north will allow winds to back off a bit, although it will still be breezy. A benign unsettled period is expected later Friday as a flat wave of low pressure moves quickly east northeast across our area. This will produce a brief bout of light rainfall with milder air in place. This is the start, however, of a longer period of more unsettled or at least cloudier weather that will take us into the weekend. Additional low pressure waves are likely to run out south of our area during the weekend, and guidance usually struggles to figure out how these will evolve. But basically the idea is clouds will rule, some sun can’t be ruled out, nor can a little light rainfall (still expecting it to be too mild for any mix/snow) during the weekend, but if pressed for more details, I’d venture to say most of the weekend will actually end up rain-free. Refining and better detailing of the forecast for these days will take place in the next couple updates.

TODAY: Mostly sunny morning. Partly sunny afternoon. Highs 37-44. Wind W 5-15 MPH, higher gusts.

TONIGHT: Variably cloudy evening. Mostly clear overnight. Lows 23-30. Wind WSW up to 10 MPH.

THURSDAY: Sunny to partly cloudy. Highs 41-48. Wind WSW 5-15 MPH.

THURSDAY NIGHT: Increasing clouds. Lows 31-38. Wind S 5-15 MPH, higher gusts possible.

FRIDAY: Mainly cloudy. Light rain possible in the afternoon. Highs 46-51. Wind S 5-15 MPH, higher gusts.

FRIDAY NIGHT: Cloudy with rain likely evening. Breaking clouds overnight. Lows 33-40. Wind W up to 10 MPH.

SATURDAY: Lots of clouds, partial sun. Highs 42-49. Wind SW up to 10 MPH.

SATURDAY NIGHT: Mostly cloudy. Lows 32-39. Wind N up to 10 MPH.

SUNDAY: Mostly cloudy. Highs 41-48. Wind NE 5-15 MPH.

DAYS 6-10 (DECEMBER 4-8)

Potential wet weather to start the period as low pressure passes south of the region with high pressure to the north, then mainly dry weather as most low pressure is held to the south and east of the region through the middle and into the latter portion of next week. An upper disturbance may trigger a few rain and snow showers in the region a time or two. No significant temperature extremes.

DAYS 11-15 (DECEMBER 9-13)

Trending away from blocking and more west to east flow, but split jet stream with weaker systems. A couple of opportunities for precipitation exist but not looking for major storminess that lingers. Overall temperatures near to above normal / precipitation near normal.

DAYS 1-5 (NOVEMBER 28 – DECEMBER 2)

Broad high pressure well to our south will slide eastward over the next few days. This, combined with low pressure to our north, will result in a broad westerly flow through Thursday. Today there will be a northwesterly component to the flow and it will be the windiest, and coldest day of the next 3, along with the possibility that a few Great Lakes snow showers survive as light snow and/or rain showers into our region. The flow backs slightly to the west Wednesday, still a chilly but slightly less windy day, and a little more to the west southwest Thursday, which will be breezy and a little milder. On Friday, a quick-moving elongated disturbance will move in from the west southwest with wet weather likely in the afternoon and evening. This system will exit for a return to dry and slightly cooler weather for Saturday with the wind flow shifting back to west northwest again, tapping a little bit into the Canadian chill.

TODAY: Intervals of clouds and sun. A passing snow or rain shower possible. Highs 35-42. Wind WNW 10-20 MPH, higher gusts.

TONIGHT: Partly cloudy. Lows 20-27. Wind W 5-15 MPH, higher gusts.

WEDNESDAY: Partly cloudy. Highs 37-44. Wind W 5-15 MPH, higher gusts.

WEDNESDAY NIGHT: Variably cloudy. Lows 23-30. Wind WSW 5-15 MPH, higher gusts.

THURSDAY: Partly sunny. Highs 40-47. Wind WSW 5-15 MPH, higher gusts.

THURSDAY NIGHT: Mostly clear. Lows 27-34. Wind SW 5-15 MPH.

FRIDAY: Increasing clouds. Rain arriving during the afternoon. Highs 43-50. Wind S 5-15 MPH.

FRIDAY NIGHT: Cloudy with rain likely evening. Clearing overnight. Watch for patchy black ice pre-dawn. Lows 25-32. Wind shifting to WNW 5-15 MPH.

SATURDAY: Partly sunny. Highs 40-47. Wind WNW 5-15 MPH.

DAYS 6-10 (DECEMBER 3-7)

Unsettled weather is most likely early in the period with the best rain chance associated with milder air and passing low pressure December 4. Blocking pattern should be slightly stronger than shown on guidance and keep most additional storminess to the south of our area into the middle of next week while we are seasonably chilly with a few snow/rain showers around at times.

DAYS 11-15 (DECEMBER 8-12)

Trending away from blocking and more west to east flow, but split jet stream with weaker systems. A couple of opportunities for precipitation exist but not looking for major storminess that lingers. Overall temperatures near to above normal / precipitation near normal.

DAYS 1-5 (NOVEMBER 27 – DECEMBER 1)

This week will feature some wind and variability in temperature, but not too much in the way of precipitation beyond the slug of heavier rain that fell last night. That was from a rapidly-moving, quickly-intensifying low pressure area that cut across southeastern New England then raced away via the Gulf of Maine. This low become part of a broad low pressure circulation that, in combination with high pressure over the southeastern US, will bring us breezy weather and a chill-down into midweek. Today actually starts out mild but high temps will be realized before noon, and then a fall-off will take place. Colder air is transported into our region tonight through Wednesday on a gusty northwesterly breeze. As that high far to the south slides its way east northeastward, it will help turn our wind around to a more southwesterly direction by Thursday, and we’ll see temperature respond accordingly with moderation for the final day of the month. As we begin December on Friday, clouds will advance in ahead of a wave of low pressure which is expected to bring us milder air and some rain for late Friday.

TODAY: Sun and passing clouds. Highs 47-54 occurring by late morning, then cooling through the 40s during the afternoon. Wind W 10-15 MPH, gusts 20-25 MPH.

TONIGHT: Partly cloudy. Lows 24-31. Wind NW 10-15 MPH, higher gusts.

TUESDAY: Partly cloudy. Highs 35-42. Wind NW 10-20 MPH, higher gusts.

TUESDAY NIGHT: Partly cloudy. Lows 20-27. Wind NW 5-15 MPH, higher gusts.

WEDNESDAY: Partly cloudy. Highs 36-43. Wind NW 5-15 MPH, higher gusts.

WEDNESDAY NIGHT: Variably cloudy. Lows 23-30. Wind W 5-15 MPH, higher gusts.

THURSDAY: Partly sunny. Highs 40-47. Wind SW 5-15 MPH, higher gusts.

THURSDAY NIGHT: Mostly clear. Lows 27-34. Wind SW 5-15 MPH.

FRIDAY: Increasing clouds. Rain arriving during the afternoon. Highs 43-50. Wind S 5-15 MPH.

DAYS 6-10 (DECEMBER 2-6)

Dry with a cooling trend over the weekend of December 2-3. Wave of low pressure brings rain chance a December 4. Dry weather returns December 5-6. Temperatures cool slightly early period, moderate mid period, cool down late period, but averaging near to slightly above normal overall.

DAYS 11-15 (DECEMBER 7-11)

Split flow pattern. Southern jet stream keeps most moisture south of our area. Northern jet stream brings a couple quick-moving disturbances with precipitation threats but no major storms. Temperatures variable, averaging near to slightly above normal. There is expected to be negative NAO induced blocking in the pattern, but I do think this blocking will be stronger than forecast, hence a further south impact for storminess.

DAYS 1-5 (NOVEMBER 26-30)

Down the home stretch of November we go. Coming out of Thanksgiving Weekend we have some weather changes ahead. Today’s not a bad day to finish off the long weekend – a tad less chilly than yesterday, but we’ll start to lose the sun as the day goes on. We have a trough approaching from the west and low pressure approaching from the southwest and the two will combine to bring us a slug of rain later tonight and early Monday. The low pressure area to the south will be tracking right across southeastern New England (just a little further north than I’d forecast previously). It’s also going to be intensifying fairly rapidly as it passes by and exits via the Gulf of Maine Monday morning. This is going to create a period of strong and gusty winds for eastern MA, particularly Cape Cod, where gusts over 50 MPH are possible for a few hours. While it stays windy, the winds will diminish a little bit as it clears out during the day Monday with dry air moving in behind the system. Tuesday through Thursday will be dry days with a chilly northwesterly flow to start and slightly milder westerly flow after that. This pattern comes about by us being between low pressure in eastern Canada and sprawling high pressure that moves from the Plains to the Southeast. A trough swings through the region later Wednesday or early Thursday but is not expected to produce any precipitation – just some clouds.

TODAY: Increasing clouds. Highs 42-49. Wind variable to SE up to 10 MPH.

TONIGHT: Thickening clouds. Rain late evening through overnight hours. Lows 38-45. Wind SE 5-15 MPH.

MONDAY: Cloudy through mid morning with rain ending west to east. Sun/cloud mix late morning on. Highs 47-54, warmest southeastern MA. Wind variable 5-15 MPH with higher gusts early becoming N 15-25 MPH with gusts over 30 MPH inland and over 40 MPH eastern coastal areas, strongest Cape Cod, becoming NW 10-20 MPH with higher gusts midday on.

MONDAY NIGHT: Partly cloudy. Lows 22-29. Wind NW 5-15 MPH, higher gusts.

TUESDAY: Partly cloudy. Highs 35-42. Wind NW 10-20 MPH, higher gusts.

TUESDAY NIGHT: Partly cloudy. Lows 20-27. Wind NW 5-15 MPH, higher gusts.

WEDNESDAY: Partly cloudy. Highs 36-43. Wind NW 5-15 MPH, higher gusts.

WEDNESDAY NIGHT: Variably cloudy. Lows 23-30. Wind W 5-15 MPH, higher gusts.

THURSDAY: Partly sunny. Highs 40-47. Wind W 5-15 MPH, higher gusts.

DAYS 6-10 (DECEMBER 1-5)

Minor precipitation threat exists late December 1 to early December 2. Another precipitation threat, more likely rain than snow, December 4. Pattern doesn’t favor major storms as systems organize after they pass. Temperatures variable, averaging near normal.

DAYS 11-15 (DECEMBER 6-10)

Continued idea of a pattern that keeps southern stream moisture to our south and minor system passing through from the northern jet stream. Temperatures variable, averaging near normal.

DAYS 1-5 (NOVEMBER 25-29)

High pressure moves into our region today providing cold but fairly tranquil weather as a noticeable breeze becomes less impactful with time. High pressure drifts off to the east and south on Sunday as a trough of low pressure approaches from the west and another low develops to the southwest. Ahead of these disturbances and post-high pressure we see the wind flow turn southeast. The combination of these factors leads to increasing clouds and as the systems move through the region Sunday night into Monday we’ll have a period of rain across the region – too mild for snow other than maybe a brief mix in some interior higher elevations, particularly southwestern NH, at the very start of the precipitation. This system exits later Monday and we dry out, and return to a chilly northwesterly air flow for Tuesday and Wednesday.

TODAY: Mostly sunny. Highs 33-40. Wind N 5-15 MPH, higher gusts, diminishing.

TONIGHT: Mostly clear. Lows 20-27. Wind N-NE under 10 MPH.

SUNDAY: Clouding up. Highs 42-49. Wind NE shifting to SE up to 10 MPH.

SUNDAY NIGHT: Cloudy. Rain likely. Lows 39-46. Wind SE 5-15 MPH.

MONDAY: Cloudy with rain in the morning. Breaking clouds in the afternoon. Highs 45-52. Wind E 5-15 MPH shifting to NW.

MONDAY NIGHT: Partly cloudy. Lows 22-29. Wind NW 5-15 MPH, higher gusts.

TUESDAY: Partly cloudy. Highs 35-42. Wind NW 10-20 MPH, higher gusts.

TUESDAY NIGHT: Partly cloudy. Lows 20-27. Wind NW 5-15 MPH, higher gusts.

WEDNESDAY: Partly cloudy. Highs 36-43. Wind NW 5-15 MPH, higher gusts.

DAYS 6-10 (NOVEMBER 30 – DECEMBER 4)

Minor precipitation threat exists late December 1 to early December 2. Another precipitation threat at the end of the period. No major storms. Temperatures near to below normal.

DAYS 11-15 (DECEMBER 5-9)

A forecast blocking pattern by medium range guidance may come to pass but will probably be stronger than forecast, forcing a slightly more active southern jet storm track to keep its systems mostly south of our region. Overall regime in that case is seasonably chilly and mainly dry. Will monitor.

DAYS 1-5 (NOVEMBER 24-28)

An elongated area of high pressure is helping to provide us with dry weather that will last through pretty much all of the extended weekend. The center of the high is actually very far from here – in North Dakota – as of this morning, but it will drift its way eastward and shrink somewhat until it is located east of New England by later Sunday. Meanwhile, we’re in a broad scale northwesterly air flow between that high and a low pressure circulation over the Canadian Maritimes. In this flow, a cold front will pass through our region later today, delivering a colder air mass tonight and Saturday, but Saturday will be a less windy day as that elongated high traverses the region. As for cloudiness, patchy stratocumulus clouds remain this morning from an extensive blanket of it that came into the region overnight, but they will continue to erode away today with plenty of sun. Filaments of high level clouds can cross the sky at times today and Saturday with the advance of warmer air aloft. Clouds will begin to overtake the sky during Sunday with more high to mid level moving in ahead of low pressure, and a broad scale onshore flow bringing in lower level moisture. Sunday night and Monday morning is our best shot of rain as low pressure passes through the region. This system will consist of a low pressure area passing by to the north and a stronger coastal / ocean system passing by to our southeast. But they don’t really get together to maximize rain/wind here, so we just have a slug of wet weather and then it dries later Monday. By Tuesday, we’re in a dry but chilly northwesterly air flow with fair weather and below normal temperatures.

TODAY: Partly cloudy morning. Mostly sunny afternoon. Highs 41-48. Wind W 5-15 MPH with higher gusts, shifting to NW by late-day.

TONIGHT: Mostly clear. Lows 20-27. Wind NW 5-15 MPH, higher gusts.

SATURDAY: Mostly sunny. Highs 33-40. Wind N 5-15 MPH, higher gusts, diminishing.

SATURDAY NIGHT: Mostly clear. Lows 20-27. Wind N-NE under 10 MPH.

SUNDAY: Clouding up. Highs 42-49. Wind NE shifting to SE up to 10 MPH.

SUNDAY NIGHT: Cloudy. Rain likely. Lows 39-46. Wind SE 5-15 MPH.

MONDAY: Cloudy with rain in the morning. Breaking clouds in the afternoon. Highs 45-52. Wind E 5-15 MPH shifting to NW.

MONDAY NIGHT: Partly cloudy. Lows 22-29. Wind NW 5-15 MPH, higher gusts.

TUESDAY: Partly cloudy. Highs 35-42. Wind NW 10-20 MPH, higher gusts.

DAYS 6-10 (NOVEMBER 29 – DECEMBER 3)

A couple of weak disturbances pass by in a northwesterly air flow during the last couple days of November with a rain or snow shower possible, otherwise dry with temperatures near to below normal. Continued chilly regime into early December. Minor precipitation threat late December 1 to early December 2, otherwise a mainly dry pattern.

DAYS 11-15 (DECEMBER 4-8)

Precipitation threat early in the period with passing low pressure, then a return to mainly dry weather. Temperatures near to below normal.

DAYS 1-5 (NOVEMBER 23-27)

Happy Thanksgiving to all! It’s going to be a nice holiday, weather-wise. We’ll see some passing clouds especially for a while later this morning to midday, otherwise sunshine will be dominant, along with a gusty breeze, which develops this morning as the sun mixes the air, and slackens again later in the day as the sun sinks lower in the sky again. While the breeze will be a chilly one, the air will be fairly seasonable with temperatures topping out around 50. So no weather problems for morning runs, high school football games, local travel, after-dinner walks, etc. Dry weather will also continue for the majority if not all of the extended holiday weekend. It isn’t until Sunday night that we see a chance of rain from approaching low pressure. Before that though we have a gusty breeze and passing clouds Friday with a cold front swinging through, but no chance of any precipitation with the front. It will deliver colder air for Saturday but high pressure will build over the region and help the wind to diminish that day. Clouds roll in Sunday, both the high and mid level variety from the southwest ahead of the low, and some lower clouds off the ocean as the wind turns southeasterly. Our best shot of rain comes Sunday night and the first half of Monday as low pressure passes by just to our southeast, and improvement follows later Monday as the low pressure area pulls away…

TODAY (THANKSGIVING): Sun/cloud mix. Highs 46-53. Wind NW 10-20 MPH with higher gusts, shifting to W and gradually diminishing.

TONIGHT: Partly cloudy. Lows 31-38. Wind W 5-15 MPH.

FRIDAY: Partly cloudy. Highs 41-48. Wind W shifting to NW increasing to 10-20 MPH with higher gusts.

FRIDAY NIGHT: Mostly clear. Lows 20-27. Wind NW to N 5-15 MPH, higher gusts.

SATURDAY: Mostly sunny. Highs 33-40. Wind N 5-15 MPH, higher gusts, diminishing.

SATURDAY NIGHT: Mostly clear. Lows 20-27. Wind N-NE under 10 MPH.

SUNDAY: Clouding up. Highs 42-49. Wind NE shifting to SE up to 10 MPH.

SUNDAY NIGHT: Cloudy. Rain likely. Lows 39-46. Wind SE 5-15 MPH.

MONDAY: Cloudy with rain in the morning. Breaking clouds in the afternoon. Highs 45-52. Wind E 5-15 MPH shifting to NW.

DAYS 6-10 (NOVEMBER 28 – DECEMBER 2)

End of November / first days of December see a northwesterly flow with a dry and chilly pattern dominating.

DAYS 11-15 (DECEMBER 3-7)

Pattern remains dry/chilly to start. May need to watch for some precipitation mid to late period.

DAYS 1-5 (NOVEMBER 22-26)

Some folks saw snow last night, pretty much where expected, and some accumulation occurred even further south and east than I had forecast. Mostly coatings to around 1 inch occurred over interior MA and southern NH, with 2-4 inches in the highest elevations of north central MA and southern NH. Some of those areas will hold on to slushy snow cover today, despite the rain that has occurred since. Where less snow fell, it’s all gone but a little slush early today, and will completely vanish during the day. Low pressure cutting across southeastern New England is bringing us wet and breezy weather, with most of the remaining rain to fall through midday. After that, it’s a drying trend with continued gusty winds as the low strengthens while moving offshore and away. The clearing won’t really take place until tonight. The remainder of the outlook is essentially unchanged, with a fair, breezy, cool (but not too cold) Thanksgiving Day, then a cold front swinging through on Friday with a few clouds, otherwise fair weather and a gusty breeze. The balance of the weekend will feature dry, less windy, but cold weather Saturday, and clouds moving in both at high levels from the west and south ahead of the next storm system, as well as lower clouds coming in from the ocean as we see the wind turn southeasterly. Wet weather is expected to hold off until Sunday night, but at day 5 there’s still some uncertainty on timing, so catch future updates…

TODAY: Overcast with rain likely through midday. Cloudy remainder of day with patchy drizzle early afternoon. Highs 48-55 occurring in the morning, mildest in southeastern MA / RI. Wind SE 5-15 MPH with higher gusts, becoming variable for a while, then N 15-25 MPH with higher gusts later in the day. A brief period of wind gusts over 30 MPH inland and 40 MPH at the coast in the late afternoon / early evening.

TONIGHT: Clearing. Lows 32-39. Wind NW 10-20 MPH, gusty.

THURSDAY (THANKSGIVING): Sun/cloud mix. Highs 46-53. Wind NW 10-20 MPH with higher gusts, shifting to W and gradually diminishing.

THURSDAY NIGHT: Partly cloudy. Lows 31-38. Wind W 5-15 MPH.

FRIDAY: Partly cloudy. Highs 41-48. Wind W shifting to NW increasing to 10-20 MPH with higher gusts.

FRIDAY NIGHT: Mostly clear. Lows 20-27. Wind NW to N 5-15 MPH, higher gusts.

SATURDAY: Mostly sunny. Highs 33-40. Wind N 5-15 MPH, higher gusts, diminishing.

SATURDAY NIGHT: Mostly clear. Lows 20-27. Wind N-NE under 10 MPH.

SUNDAY: Clouding up. Highs 40-47. Wind NE shifting to SE up to 10 MPH.

DAYS 6-10 (NOVEMBER 27 – DECEMBER 1)

Wet start November 27 as low pressure passes through. Frontal system may bring a few rain showers November 29, and another a few rain or snow showers to start December, otherwise the pattern trend is drier and chilly as we head through the final days of November to the beginning of December.

DAYS 11-15 (DECEMBER 2-6)

Large scale pattern features a northwest flow with colder, mostly dry weather in the early days of December.
