DAYS 1-5 (OCTOBER 17-21)

This morning’s low temperatures show a wide range, which is typical for this time of year under high pressure with light wind, with inland low elevations having dropped below freezing with frost and freeze occurring, while urban centers and immediate coastal areas are relatively warmer, remaining well above freezing, even above 40 in some locations. The aforementioned high pressure area will be in control of our weather through the weekend into the early part of next week with fair weather and a general warming trend. However, the weather in part of the region will be impacted by a strengthening ocean storm, passing southeast of the region, later today into Friday. The impacts from this system will be some cloudiness over southeastern areas, a more prominent northeasterly wind in southeastern MA to southern RI, and some high tide coastal splash-over and minor flooding especially in prone areas of southeastern MA Friday. Rainfall associated with the storm will remain offshore, and the influence of the system will end as it moves further away heading into the weekend. We continue to have good sky conditions for viewing of Comet Tsuchinshan-ATLAS, which appears slightly higher in the west southwest sky about 45 minutes after sunset each evening until it sinks to the western horizon. This comet will be starting to dim day by day, so best views are likely the next couple nights – though this can be limited in southeastern areas by clouds associated with the ocean storm.

TODAY: Sun most abundant north and west and more limited south and east. Highs 53-60. Wind N-NE 5-15 MPH EXCEPT 15-25 mph Cape Cod region.

TONIGHT: Clouds linger southeastern MA / mostly clear elsewhere. Lows 33-40. Wind NE-N 5-15 MPH.

FRIDAY: Sun/cloud mix southeastern MA / RI. Sunnier elsewhere. Highs 55-62. Wind N 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Lows 38-45. Wind W up to 10 MPH.

SATURDAY: Mostly sunny. Highs 61-68. Wind W 5-15 MPH.

SATURDAY NIGHT: Clear. Fog patches low elevations. Lows 42-49. Wind W under 10 MPH.

SUNDAY: Mostly sunny. Highs 65-72. Wind SW 5-15 MPH, higher gusts.

SUNDAY NIGHT: Clear. Fog patches low elevations. Lows 44-51. Wind SW under 10 MPH.

MONDAY: Mostly sunny. Highs 66-73. Wind SW 5-15 MPH.

DAYS 6-10 (OCTOBER 22-26)

Dry pattern. The only unsettled weather chance is a passing rain shower chance sometime later October 23 or October 24 with a cold front passing by, based on current expected timing. Mild early period, cooler later period.

DAYS 11-15 (OCTOBER 27-31)

Similar pattern though in the larger scale systems may be more dynamic. Still, the trend is for it to be on the drier side here, again with probably only one brief interruption from a passing frontal system around mid period. Obviously can’t get too detailed this far out and will monitor and update.

DAYS 1-5 (OCTOBER 16-20)

A trough at upper levels and surface high pressure to our west will give us basically a repeat of yesterday’s weather – breezy, cool, a sun/cloud mix. Tonight, with a clearing sky and wind dropping off as high pressure builds over the region, radiational cooling allows many inland areas to drop to near to below freezing for the first time this autumn, though it won’t be quite as cold in urban centers and along the immediate coastline due to warming influences of buildings / cement / asphalt in urban areas and the “warmer” ocean water adjacent to the shoreline. Also, a blanket of stratus from the ocean may invade Cape Cod and adjacent southeastern MA into parts of RI during the pre-dawn of Thursday with a light northeasterly air flow in those areas. Our weather Thursday through Sunday will be governed by a large area of high pressure. Thursday and Friday will still be on the cooler side with a north to northeast wind, enhanced in eastern and southern coastal areas with an ocean storm well to our southeast. This storm, despite the distance of its low pressure center from our area, will push its high to middle cloud canopy at least into southeastern areas for a while during Thursday to early Friday. The largely mostly clear to clear evening sky forecast the next several days is good news for viewing of Comet Tsuchinshan-ATLAS, which appears slightly higher in the west southwest sky about 45 minutes after sunset each evening until it sinks to the western horizon.

TODAY: Sun/cloud mix. Highs 52-59. Wind NW 5-15 MPH, gusts 20+ MPH.

TONIGHT: Clearing, except some low clouds from ocean southeastern MA and parts of RI. Lows 27-34 except 35-42 urban centers / oceanside. Wind N diminishing to under 10 MPH.

THURSDAY: Sun most abundant north and west and more limited south and east. Highs 53-60. Wind N-NE 5-15 MPH EXCEPT 15-25 mph Cape Cod region.

THURSDAY NIGHT: Clouds linger southeastern MA / mostly clear elsewhere. Lows 33-40. Wind NE-N 5-15 MPH.

FRIDAY: Mostly sunny. Highs 55-62. Wind N 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Lows 38-45. Wind W up to 10 MPH.

SATURDAY: Mostly sunny. Highs 61-68. Wind W 5-15 MPH.

SATURDAY NIGHT: Clear. Fog patches low elevations. Lows 42-49. Wind W under 10 MPH.

SUNDAY: Mostly sunny. Highs 65-72. Wind SW 5-15 MPH.

DAYS 6-10 (OCTOBER 21-25)

Dry spell early to mid portion of next week with near to above normal temperatures. Watch for a disturbance or two passing by later in the week with an unsettled weather opportunity.

DAYS 11-15 (OCTOBER 26-30)

Slow evolution of a more dynamic pattern but the overall weather is still on the drier side here with a little more pronounced temperature swing potential and more wind potential.

Previous Post

DAYS 1-5 (OCTOBER 15-19)

A dry pattern is in control. Cool weather dominates through Thursday. Atlantic Canada low pressure combined with Midwest high pressure drives a northwesterly breeze across the region today with plenty of sun overall, but some diurnal cumulus and stratocumulus developing, most prominent in the hills well west and north of Boston, while some streamers of high clouds cross the sky from the west southwest during the afternoon hours. Previously felt there could be more clouds Wednesday, but no longer so. High pressure exerts more control while the influence of upper level low pressure is gone sooner, and there is more sun, similar to today at “worst”. Thursday’s weather will be influenced by an ocean storm well offshore to our southeast, but close enough to turn the wind more northerly, and also extend a cloud canopy over the South Coast / Cape Cod for a while – though I do think any rainfall with this low will remain over the ocean. High pressure exerts more influence late this week along with a moderating temperature trend.

TODAY: Sunny start, then a sun/cloud mix. Highs 51-58. Wind NW 5-15 MPH.

TONIGHT: Partly cloudy. Lows 30-37, except 38-45 urban locations. Wind N 5-15 MPH.

WEDNESDAY: Sunshine dominates while a few clouds mix in at times too. Highs 51-58. Wind NW 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 32-39, milder in urban areas. Wind N up to 10 MPH.

THURSDAY: Sun dims south and east, brighter north and west. Highs 52-59. Wind N 5-15 MPH, 15-25 MPH over Cape Cod.

THURSDAY NIGHT: Clearing. Lows 31-38. Wind NW 5-15 MPH, diminishing.

FRIDAY: Mostly sunny. Highs 58-65. Wind W 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Lows 38-45. Wind W up to 10 MPH.

SATURDAY: Mostly sunny. Highs 61-68. Wind W 5-15 MPH.

DAYS 6-10 (OCTOBER 20-24)

Dry spell continues until late period when there’s finally a threat of some unsettled weather. Temperatures near to above normal through mid period before a cooling trend.

DAYS 11-15 (OCTOBER 25-29)

A more dynamic pattern may evolve, but that doesn’t necessarily mean stormy. It may mean more stark temperature contrasts and at least one bout of unsettled weather. Much to monitor and fine-tune.

DAYS 1-5 (OCTOBER 14-18)

Low pressure crosses the region then departs during the day today, bringing an overcast start to the day with pockets of rain showers, even an isolated thunderstorm potential (there were a few around yesterday and last night too). While a drying trend gets underway this afternoon, one more trough can trigger another passing shower or thunderstorm up until early evening. Tonight we see the arrival of the coolest air mass of the season to date, which will be with us into midweek. During this time high pressure extends into our region while upper level low pressure crosses it. This combination is good for a fair amount of diurnal clouds, and quite a few may form Tuesday and Wednesday, with a brief rain shower not to be rule out especially Wednesday midday or afternoon. By Thursday and Friday, the departure of the upper low and continuation of high pressure in control mean fewer clouds Thursday and abundant sunshine by Friday. While mornings will be chilly, you’ll notice a milder trend each daytime.

TODAY: Cloudy with patchy fog and scattered rain showers including a slight chance of a thunderstorm through midday. Breaking clouds and intervals of sun develop west to east this afternoon with an additional rain shower or thunderstorm possible late-day. Highs 54-61 except 61-68 RI and southeastern MA. Wind NE 5-15 MPH except variable to briefly SW in RI and southeastern MA, all shifting to NW 5-15 MPH with higher gusts later.

TONIGHT: An early rain shower potential eastern areas, otherwise clearing. Lows 35-42. Wind NW 5-15 MPH with higher gusts. Wind chill sub-freezing at times.

TUESDAY: Sunny start, then a sun/cloud mix. Highs 51-58. Wind N 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Lows 30-37, except 38-45 urban locations. Wind N 5-15 MPH.

WEDNESDAY: Clouds dominate / intervals of sun. Slight rain shower chance. Highs 50-57. Wind N to NE 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 32-39, milder in urban areas. Wind N up to 10 MPH.

THURSDAY: Sun/cloud mix. Highs 52-59. Wind N 5-15 MPH.

THURSDAY NIGHT: Clearing. Lows 31-38. Wind NW up to 10 MPH.

FRIDAY: Mostly sunny. Highs 58-65. Wind W 5-15 MPH.

DAYS 6-10 (OCTOBER 19-23)

High pressure delivers fair weather and a milder spell through mid period. Watch for a disturbance bringing a rain shower chance later in the period as well as a cooler air mass.

DAYS 11-15 (OCTOBER 24-28)

Inconsistency in day to day weather means a potential disturbance and rain shower threat will be hard to time early or mid period, otherwise the general pattern looks fairly dry with variable day-to-day temperatures averaging close to normal overall.

DAYS 1-5 (OCTOBER 13-17)

A frontal boundary draped just south of the area will struggle to move northward as a warm front today and tonight as low pressure approaches from the west. The passage of this low will take it along the frontal boundary, south of much of the WHW forecast area, as the warm sector may only barely get up into the region from the South Coast to the MA South Shore early Monday before the departing low pulls the boundary south and east. Rainfall will be most widespread north of I-90 on Sunday and then more showery in nature across the region Sunday night into Monday before it dries out. Behind this comes the coolest air mass of the season so far for Tuesday and Wednesday, along with blustery conditions. This eases Thursday as high pressure builds in with more tranquil but still cool conditions.

TODAY: Cloudy. Periods of rain, most widespread near and north of I-90. Highs 55-62. Wind E up to 10 MPH.

TONIGHT: Cloudy. Areas of fog. Rain showers likely. Lows 48-55. Wind E to SE up to 10 MPH may become variable or S to SW along the South Coast.

MONDAY: Cloudy start with rain showers likely, then rain showers diminish as clouds break for sun at times. Highs 55-62. Wind variable becoming NW and increasing to 10-20 MPH with higher gusts.

MONDAY NIGHT: Clearing. Lows 33-40. Wind NW 10-20 MPH. Wind chill below 30 at times.

TUESDAY: Sun and passing clouds. Highs 53-60. Wind NW 10-20 MPH.

TUESDAY NIGHT: Mostly clear. Lows 30-37, except 38-45 urban locations. Wind NW 5-15 MPH.

WEDNESDAY: Sun/cloud mix. Highs 53-60. Wind NW 10-20 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 28-35, milder some urban areas. Wind W up to 10 MPH.

THURSDAY: Sunny. Highs 55-62. Wind W up to 10 MPH.

DAYS 6-10 (OCTOBER 18-22)

High pressure brings fair weather through mid period at least, with a gradual moderating trend. Unsettled weather may return by period’s end.

DAYS 11-15 (OCTOBER 23-27)

Pattern looks fairly dry and seasonable heading deep into the month.

DAYS 1-5 (OCTOBER 12-16)

If you have a yard sale or outdoor projects planned today, it won’t be rainfall associated with a passing cold front that will be your nemesis. There won’t be any. But what will cause you some issues is the wind. Parenting low pressure in eastern Canada and a high pressure area to our south have quite a difference in their respective central pressures, and the gradient between them will really make the air move, blowing from the west initially and shifting to the northwest as the frontal boundary moves across the region through midday. It will be mild with high temps in the 60s, maybe touching 70 in a few places before cooler air starts to move in later. Tonight, the feel of that gusty, cool fall evening will be the real deal as the breeze keeps up, only subsiding late at night, and much cooler air arrives. The balance of the holiday weekend is going to be more unsettled, however. The front that moves by today will become stationary to our south and only make a modest push back northward as a warm front during Sunday. Approaching low pressure from the west will add moisture, so by morning we’re cloudy, and overrunning rainfall then develops from west to east. This rain is going to favor locations near and north of I-90. To the south, where the slope of the front means the warmer air will be closer to the surface means that a more showery rainfall pattern will exist there. Eventually, low pressure tracks across southern portions of the region, along the frontal boundary, bringing additional showery rain to the region Sunday night into Monday. As the low moves away, we return to a blustery, cool regime with dry weather moving in, and the coolest airmass of the season so far for Tuesday and Wednesday.

TODAY: Mostly sunny. Highs 63-70. Wind W shifting to NW, 10-20 MPH with gusts 25-35 MPH, even up to 40 MPH in some higher elevation locations.

TONIGHT: Clear evening. Increasing clouds from west to east overnight. Lows 42-49. Wind NW 10-20 MPH with higher gusts early, diminishing to under 10 MPH and becoming variable, then shifting to E toward dawn.

SUNDAY: Cloudy. Periods of rain, most especially near and north of I-90. Highs 55-62. Wind E up to 10 MPH.

SUNDAY NIGHT: Cloudy. Areas of fog. Rain showers likely. Lows 48-55. Wind E to SE up to 10 MPH may become variable or S to SW along the South Coast.

MONDAY: Cloudy start with rain showers likely, then rain showers diminish as clouds break for sun at times. Highs 55-62. Wind variable becoming NW and increasing to 10-20 MPH with higher gusts.

MONDAY NIGHT: Clearing. Lows 33-40. Wind NW 10-20 MPH. Wind chill below 30 at times.

TUESDAY: Sun and passing clouds. Highs 53-60. Wind NW 10-20 MPH.

TUESDAY NIGHT: Mostly clear. Lows 30-37, except 38-45 urban locations. Wind NW 5-15 MPH.

WEDNESDAY: Sun/cloud mix. Highs 53-60. Wind NW 10-20 MPH.

DAYS 6-10 (OCTOBER 17-21)

High pressure brings fair weather through mid period at least, with a gradual moderating trend. Unsettled weather may return by period’s end.

DAYS 11-15 (OCTOBER 22-26)

Unsettled weather potential early period, then fair weather returns. Variable temperatures, averaging near to slightly above normal.

DAYS 1-5 (OCTOBER 11-15)

High pressure brings fair weather with a milder trend through Saturday as the center of high pressure to the south will allow moderation from west to east across the Northeast. However this is not a turn to a warmer pattern. There are other changes upcoming and we’ll see those get underway during the holiday weekend. A dry cold front will whistle through the region during Saturday, delivering some gusty wind and a quick cool-down at night in contrast to a pretty mild day. Low pressure will come at us via the Great Lakes on Sunday, and its warm front will bring a shot at some rainfall before we break into the warm sector briefly sometime that evening into early Monday. At that time, a cold front will cross the region with additional showers and gusty wind, the latter of which will hang around during the balance of the day, shifting to northwest and delivering another Canadian air mass, the coolest of the autumn so far, which you’ll really notice heading toward mid week.

TODAY: Sunshine filtered at times by passing patches of high cloudiness. Highs 60-67. Wind W 5-15 MPH.

TONIGHT: Mostly clear. Lows 46-53. Wind SW up to 10 MPH.

SATURDAY: Mostly sunny. Highs 66-73. Wind SW 5-15 MPH shifting to NW.

SATURDAY NIGHT: A few cloud patches early, departing to the southeast. Overnight high cloud shield increasing west to east. Lows 42-49. Wind NW 5-15 MPH and gusty early, diminishing, becoming variable under 10 MPH.

SUNDAY: Clouds thicken first thing with a period of rain in the morning. Mostly cloudy with passing rain showers possible midday and afternoon. Highs 60-67. Wind SE under 10 MPH then SW 5-15 mph.

SUNDAY NIGHT: Cloudy. Areas of fog. Rain showers likely. Lows 54-61. Wind SW 5-15 MPH.

MONDAY: Cloudy start with rain showers likely, then a sun/cloud mix. Highs 60-67 in the morning then cooling into the 50s. Wind SW 5-15 MPH shifting to NW and increasing to 10-20 MPH.

MONDAY NIGHT: Mostly clear. Lows 33-40. Wind NW 10-20 MPH. Wind chill below 30 at times.

TUESDAY: Sun and passing clouds. Highs 53-60. Wind NW 10-20 MPH.

DAYS 6-10 (OCTOBER 16-20)

A very chilly air mass around mid week, moderating gradually later next week. An upper low may deliver a quick shower of rain or snow early October 16, otherwise this will be a dry stretch of weather as upper level low pressure gives way to zonal flow and surface high pressure. Additionally, after we get rid of an initial period of windy weather, calmer conditions should allow for fairly widespread frost and even some light freezing conditions mid week next week, exceptions urban centers and immediate seacoasts. More about this later…

DAYS 11-15 (OCTOBER 21-25)

Trend remains for continued fairly dry pattern and up-and-down temperatures but averaging slightly above normal for the period.

DAYS 1-5 (OCTOBER 10-14)

Canadian cool shot today with a gusty breeze as high pressure slides southeastward to our west and upper level low pressure weakens but moves across the region. Surface high pressure moves south of New England Friday and Saturday which will feature dry weather and a milder trend. A cold front will pass by later Saturday with a gusty, shifting breeze. Unsettled weather will follow this as a wave of low pressure approaches then moves just to our north, dragging its warm front through the region Sunday with a period of rain and a cold front sometime early to midday Monday with another round of rain showers. There should be a milder period of time between the 2 fronts with less chance of wet weather in the “warm sector”, but it’s pretty clear that the weather “pick” of the 3-day weekend will be Saturday.

TODAY: Sun and passing clouds. Highs 57-64. Wind NW 5-15 MPH and gusty.

TONIGHT: Mostly clear. Lows 37-44. Wind NW 5-15 MPH, then diminishing.

FRIDAY: Mostly sunny. Highs 60-67. Wind W 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Lows 46-53. Wind SW up to 10 MPH.

SATURDAY: Mostly sunny. Highs 66-73. Wind SW 5-15 MPH.

SATURDAY NIGHT: Evening clouds depart northwest to southeast. Overnight clouds increasing west to east. Lows 42-49. Wind NW 5-15 MPH with higher gusts early, diminishing and becoming variable, then SE under 10 MPH.

SUNDAY: Mostly cloudy. A period of rain in the morning or midday, then a slight chance of rain showers. Highs 60-67. Wind SE up to 10 MPH shifting to SW and increasing to 5-15 MPH.

SUNDAY NIGHT: Mostly cloudy. Chance of rain showers. Areas of fog. Lows 53-60. Wind SW 5-15 MPH.

MONDAY: Mostly cloudy with a chance of rain showers in the morning, then a sun/cloud mix. Highs 60-67. Wind SW 10-20 MPH shifting to NW.

DAYS 6-10 (OCTOBER 15-19)

Dry pattern. Below normal temps (coolest of season so far) early period, then moderation follows.

DAYS 11-15 (OCTOBER 20-24)

Trend is for continued fairly dry pattern and up-and-down temperatures but averaging slightly above normal for the period.

DAYS 1-5 (OCTOBER 9-13)

Upper level low pressure dominates our weather again the next couple days. A surprise batch of showers and thunderstorms popped up and moved across far southeastern areas / Cape Cod around dawn, and is moving off. I’m not expecting really anything else in the way of shower activity today though, just some areas of cloudiness to share the sky with the sun. A cold front will cross the region this evening with perhaps a quick shower in southern NH and northern MA, and reinforce a cool air mass for Thursday. High pressure slides south of our region and allows it to moderate Friday and Saturday, before another cold front knocks the temps back down for Sunday, just in time for a wave of low pressure to ride along it and bring clouds and a chance of some rainfall to the region for the middle day of the holiday weekend.

TODAY: Sunrise showers/t-storms exit Cape Cod otherwise a sun/cloud mix. Highs 59-66. Wind W 5-15 MPH.

TONIGHT: Partly cloudy. An evening shower possible southern NH / northern MA. Lows 41-48. Wind W 5-15 MPH shifting to NW.

THURSDAY: Partly cloudy. Highs 56-63. Wind NW 10-20 MPH.

THURSDAY NIGHT: Mostly clear. Lows 35-42 except milder in urban centers. Wind NW diminishing to under 10 MPH.

FRIDAY: Mostly sunny. Highs 60-67. Wind W 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Lows 46-53. Wind SW up to 10 MPH.

SATURDAY: Mostly sunny. Highs 66-73. Wind SW 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 42-49. Wind NW 10-20 MPH, diminishing and becoming variable.

SUNDAY: Clouding over. Chance of rain. Highs 58-65. Wind variable 5-15 MPH.

DAYS 6-10 (OCTOBER 14-18)

Monday Holiday October 14 features a lingering shower otherwise mainly dry, breezy, cool weather. High pressure dominates with dry, cool weather followed by moderation next week.

DAYS 11-15 (OCTOBER 19-23)

Watching October 19-20 for potential unsettled weather, otherwise pattern is dry and overall seasonable though with variable temperatures.

DAYS 1-5 (OCTOBER 8-12)

Upper level low pressure is the main driver of the weather the next few days, but that doesn’t mean unsettled weather. In this case, it means mostly fair weather, just some clouds from time to time, and a secondary cold front which will cross the region late Wednesday to reinforce the cooler air from Canada that’s now taking over behind yesterday’s unsettled weather. By Friday, high pressure slides over the region with a very nice and slightly milder day, and this high heads offshore with continued fair weather and a further warm-up for Saturday, the first day of a (for many) 3-day weekend.

TODAY: Sun and passing clouds. Highs 58-65. Wind NW 5-15 MPH.

TONIGHT: Mostly clear to partly cloudy. Areas of frost inland lower elevations. Lows 38-45 except colder in some inland lower elevations and milder in urban centers. Wind NW under 10 MPH.

WEDNESDAY: Sun/cloud mix. Highs 59-66. Wind W 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 40-47. Wind W 5-15 MPH shifting to NW>

THURSDAY: Partly cloudy. Highs 56-63. Wind NW 10-20 MPH.

THURSDAY NIGHT: Mostly clear. Lows 35-42 except milder in urban centers. Wind NW diminishing to under 10 MPH.

FRIDAY: Mostly sunny. Highs 60-67. Wind W 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Lows 46-53. Wind SW up to 10 MPH.

SATURDAY: Mostly sunny. Highs 66-73. Wind SW 5-15 MPH.

DAYS 6-10 (OCTOBER 13-17)

Quicker-moving features anticipated now bringing unsettled weather threat in the October 13-14 time frame, the middle and end of the holiday weekend. Will refine this outlook in coming updates. Fair, cooler middle of next week.

DAYS 11-15 (OCTOBER 18-22)

Watching October 18-19 for potential unsettled weather, otherwise pattern is dry and overall seasonable though with variable temperatures.

DAYS 1-5 (OCTOBER 7-11)

A cold front crosses the region from west to east today with a round of showers, fairly good coverage but not too heavy with rainfall amounts mostly under 1/2 inch. A few areas could see an embedded downpour, even a thunderstorm, and receive over 1/2 inch, but this will be the exception rather than the rule. The trend for showers ending and clouds breaking will develop from west to east during mid to late afternoon after the front passes. A cooler westerly to northwesterly air flow arrives tonight through Tuesday as a Canadian air mass arrives and brings the true feel of fall. A high pressure bubble moves across the region Tuesday night and early Wednesday, providing an opportunity for radiational cooling the the first frost for many interior areas (away from coastal areas and urban centers). With an upper level trough driving the weather pattern, and a secondary cold front to pass by Wednesday night / early Thursday, some clouds move through and a more active breeze should prevent any frost formation during that period, but I suspect any shower activity will stay north of our area as the air mass will be very dry both ahead of and behind that front. Thursday will be the coolest day of the week – cool air combined with a continued active breeze. Friday will see moderation with plenty of sun and less wind, though it will be quite chilly to start the day before a nice temperature recovery occurs.

TODAY: A hint of sun eastern areas at sunrise and breaks of sun late-day favoring areas west of I-95, otherwise mainly cloudy with episodes of rain showers and a slight chance of a thunderstorm. Highs 62-69. Wind S 5-15 MPH, shifting to W from west to east during midday and afternoon.

TONIGHT: Clearing. Lows 43-50. Wind W 5-15 MPH.

TUESDAY: Sun and passing clouds. Highs 58-65. Wind NW 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Areas of frost inland lower elevations. Lows 38-45 except colder in some inland lower elevations and milder in urban centers. Wind NW under 10 MPH.

WEDNESDAY: Sunny through midday. Some clouds arrive west to east later. Highs 59-66. Wind W 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 40-47. Wind W 5-15 MPH shifting to NW>

THURSDAY: Partly cloudy. Highs 56-63. Wind NW 10-20 MPH.

THURSDAY NIGHT: Mostly clear. Lows 35-42 except milder in urban centers. Wind NW diminishing to under 10 MPH.

FRIDAY: Mostly sunny. Highs 60-67. Wind W 5-15 MPH.

DAYS 6-10 (OCTOBER 12-16)

Holiday Weekend Outlook: Saturday October 12 looks dry and mild with a west wind and high pressure ridge building. Sunday October 13 looks rain-free but clouds may show up ahead of the next trough. Monday October 14 shows indications of unsettled weather with a trough bringing a rain chance. Fair and cooler weather returns later in the period behind that.

DAYS 11-15 (OCTOBER 17-21)

A mid period interruption of unsettled weather is a potential with fair weather otherwise continuing its dominance. Temperatures will be variable but not all that far from what would be expected overall.

DAYS 1-5 (OCTOBER 6-10)

High pressure brings fair weather today but its center to our north allows a low level air flow from the northeast, which will bring some ocean clouds into coastal areas, most especially Cape Cod, limiting the sun at times. This afternoon, you’ll notice some high level clouds starting to move in from the west and northwest ahead of an approaching trough. A surface low associated with this feature will pass to our north on Monday, dragging its warm front quietly through in the pre-dawn hours, but a more productive cold front follows this from west to east across the region during Monday. While shower activity will be widespread, rainfall amounts will likely be unimpressive, with under 1/2 inch of rain expected for most of the region. A few embedded heavier showers could push a few areas over 1/2 inch of rain. Overall, this will be a non-beneficial event to battle the building abnormally dry and moderate drought conditions now observed in much of southern New England, and beyond this, another dry stretch looms. Other than an isolated spot afternoon shower from an upper level disturbance passing by on Wednesday, expect dry weather and below normal temperatures Tuesday through midweek as a polar airmass from Canada moves in. There will be frost potential away from urban and immediate coastal areas this week, the best potential for it being Wednesday morning with a combination of light wind and clear sky allowing the best radiational cooling. There may be too much wind Thursday morning for a legitimate shot other than the lowest elevation locations.

TODAY: Sunshine but interrupted by coastal clouds especially Cape Cod. Highs 62-69, coolest coast. Wind NE 5-15 MPH.

TONIGHT: Increasing clouds. Lows 54-61. Wind SE up to 10 MPH.

MONDAY: Mainly cloudy. Periods of rain showers. Highs 62-69. Wind S 5-15 MPH becoming variable.

MONDAY NIGHT: Partly cloudy. Lows 43-50. Wind variable becoming NW 5-15 MPH.

TUESDAY: Sun and passing clouds. Highs 58-65. Wind NW 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Lows 38-45 except colder in some inland lower elevations and milder in urban centers. Wind NW under 10 MPH.

WEDNESDAY: Sun/cloud mix. A slight chance of a passing light rain shower mainly late-day. Highs 57-64. Wind NW 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 40-47. Wind N 5-15 MPH.

THURSDAY: Partly cloudy. Highs 58-65. Wind NW 5-15 MPH.

DAYS 6-10 (OCTOBER 11-15)

Some up and down temps but the overall trend is near to below normal. Two troughs / frontal systems should pass by, one around the October 12-13 weekend with limited moisture and rain shower chances – probably just dry, and a second one in the October 14-15 window with a better rain shower chance. Our weather pattern is not conducive to bringing beneficial moisture from the tropics up here.

DAYS 11-15 (OCTOBER 16-20)

Again no major changes. Some of the medium range guidance has hinted at a larger scale trough and storm system making its way into the East at some point but this doesn’t immediately mean major changes here. We may see a stronger warm up / cool down cycle with one significant rain event during the transition, but this is a long way out and many days to monitor and fine-tune that part of the outlook.

DAYS 1-5 (OCTOBER 5-9)

Our mild pattern is on its way out, but will take a couple days to fully replace. A weak cold front moving through the region first thing this morning brings a few rain showers (even a few morning rainbows – I just photographed one in Woburn!), and then it clears out and we have a mild day ahead with plenty of midday and afternoon sunshine! High pressure builds north of the area Sunday, and this will result in an onshore air flow Sunday which will likely drive some ocean stratus into at least coastal areas, and maybe some distance inland as well, robbing the region of potential sun. At the same time, later in the day, high and mid level clouds will be increasing from the west ahead of an approaching low pressure trough. This trough will arrive late at night and be with us Monday. A frontal boundary will move across the region but a wave of low pressure forming on it will prolong the unsettled weather much of the day. Despite a longer episode of cloudiness and potential rain showers, the rainfall amounts don’t look very impressive from that system. We could use more beneficial rain to battle the building abnormally dry to moderate drought conditions in the region. Beneficial rain or not, we will get a solid shot of chilly air behind that system heading toward the middle of next week.

TODAY: Clouds and scattered rain showers eastern areas into mid morning, then sun returns west to east. Highs 68-75. Wind SW 5-15 MPH shifting to NW.

TONIGHT: Mostly clear. Patchy fog. Lows 50-57. Wind N up to 10 MPH.

SUNDAY: Sunshine, becoming limited by midday. Highs 63-70, coolest coast. Wind N shifting to E 5-15 MPH.

SUNDAY NIGHT: Clouding up. Lows 55-62. Wind SE to S 5-15 MPH.

DAYS 6-10 (OCTOBER 10-14)

Cool, dry weather through mid period. A later-period warm up may lead to a rain shower chance as the next trough moves into the region end of period.

DAYS 11-15 (OCTOBER 15-19)

No outlook changes. Brief unsettled weather threats in a predominantly dry weather pattern. Temperatures variable but averaging below normal with better chance of additional frosts and first freeze for some locations.

DAYS 1-5 (OCTOBER 4-8)

A changing weather pattern means we say goodbye to our current mild stretch soon in favor of a cooler regime. But before that we have a few more days of above normal temperatures. Today will be the warmest of the next 3. A weak cold front will knock it down only slightly for the weekend as it passes by early Saturday with a minimal rain shower threat, so other than that at the very start, we’re in for a fair and mild weekend. Clouds return later Sunday though ahead of a stronger cold front, which brings a better rain shower chance mainly the first half of Monday, and a turn to significantly cooler weather by later Monday through Tuesday.

TODAY: Patchy radiation fog early, otherwise sun filtered through high clouds. Highs 71-78. Wind S up to 10 MPH.

TONIGHT: Thicker clouds arrive west to east. A rain shower chance toward dawn. Patchy fog. Lows 55-62. Wind SW up to 10 MPH.

SATURDAY: Clouds and a rain shower chance first thing in the morning eastern areas, otherwise a sun/cloud mix. Highs 68-75. Wind SW 5-15 MPH shifting to NW.

SATURDAY NIGHT: Mostly clear. Patchy fog. Lows 50-57. Wind N up to 10 MPH.

SUNDAY: Mostly sunny except some eastern coastal clouds possible. Highs 65-72. Wind N to NE up to 10 MPH.

SUNDAY NIGHT: Clouding up. Lows 55-62. Wind SE to S 5-15 MPH.

MONDAY: Cloudy with rain showers likely in the morning. Clouds break for sun at times afternoon. Highs 63-70. Wind S 5-15 MPH shifting to NW.

MONDAY NIGHT: Partly cloudy. Lows 43-50. Wind NW 5-15 MPH.

TUESDAY: Sun and passing clouds. Highs 58-65. Wind NW 5-15 MPH.

DAYS 6-10 (OCTOBER 9-13)

Cool northwest flow and other than a potential diurnal pop up rain shower October 9 and or 10 it looks dry for this period. Some areas away from urban locations and the coastline can see their first frost before next week ends.

DAYS 11-15 (OCTOBER 14-18)

Brief unsettled weather threats in a predominantly dry weather pattern. Temperatures variable but averaging below normal with better chance of additional frosts and first freeze for some locations.

DAYS 1-5 (OCTOBER 3-7)

High pressure will be in control of the weather most of the time through the weekend, with the only interruption being a rain shower chance early Saturday from a passing cold front. This front will replace the warmer air of the next couple days with slightly less warm air during the weekend. Another cold front will pass by early Monday with upper level low pressure trailing it, so Monday will feature a better shot at wet weather early, albeit fairly brief as it stands now, but the chance of an additional shower popping up with a cold pool of air arriving aloft.

TODAY: Patchy radiation fog early, otherwise a sun/cloud mix. Highs 68-75. Wind S up to 10 MPH.

TONIGHT: Mostly clear. Patchy fog. Lows 51-58. Wind S under 10 MPH.

FRIDAY: Mostly sunny. Highs 71-78. Wind S up to 10 MPH.

FRIDAY NIGHT: Variably cloudy. Patchy fog. Lows 55-62. Wind SW up to 10 MPH.

SUNDAY: Mostly sunny. Highs 65-72. Wind W up to 10 MPH.

SUNDAY NIGHT: Clouding up. Lows 55-62. Wind S 5-15 MPH.

MONDAY: Cloudy with rain showers likely in the morning. Variably cloudy with an additional rain shower possible in the afternoon. Highs 62-69. Wind S 5-15 MPH shifting to NW.

DAYS 6-10 (OCTOBER 8-12)

Passing disturbance brings a brief rain shower chance around October 10, otherwise generally dry weather and below normal temperatures are expected with an often northwesterly air flow out of Canada.

DAYS 11-15 (OCTOBER 13-17)

Brief unsettled weather threats in a predominantly dry weather pattern. Increasing chances of significant chilly air from Canada and first frosts / freezes in portions of the region.
