Low pressure to the south of New England ends its extended stay and pulls off to the east today, and clouds associated with it will follow suit and exit – with that departure taking longest from the MA South Shore to Cape Cod. But by the end of the day pretty much everybody will have seen some sun. Milder air also arrives today as the wind shifts to west and southwest. However, don’t get used to the mild weather. We get one more mild day Friday but a strong cold front crosses the region during the afternoon and evening, maybe producing a brief passing shower. This sets us up for a fair, breezy, and cool October weekend. The chilly air gets reinforced later Sunday with another cold front, keeping the cool dry regime going to start next week as well. This pattern will continue to accelerate fall foliage season, which is likely to be running ahead of normal by up to several days, and so far with strong signs of being more brilliant than last year, at least in some locations. Keep in mind that despite some decent rainfall since September, reducing drought, there are some trees that already went into “survival mode” from drought stress, and may have already dropped some leaves.

TODAY: Clouds give way to more sun, first inland, last Cape Cod region. Highs 66-73. Wind W to SW 5-15 MPH.

TONIGHT: Partly cloudy. Lows 50-57. Wind SW 5-15 MPH.

FRIDAY: Partly sunny. A brief passing rain shower possible in the afternoon. Highs 68-75. Wind SW 10-20 MPH shifting to NW from west to east by day’s end.

FRIDAY NIGHT: Partly cloudy then clearing. Lows 38-45. Wind NW 10-20 MPH, higher gusts.

SATURDAY: Sun and passing clouds. Highs 53-60. Wind NW 5-15 MPH, higher gusts.

SATURDAY NIGHT: Clear. Areas of frost in sheltered lower elevations. Lows 37-44, possibly colder in sheltered lower elevations. Wind W 5-15 MPH, higher gusts, but may drop to near calm in sheltered lower elevations..

SUNDAY: Sun/cloud mix. A late-day shower possible in southern NH. Highs 56-63. Wind W 10-20 MPH shifting to NW late-day.

SUNDAY NIGHT: Partly cloudy early, then clearing. Lows 37-44. Wind NW 5-15 MPH.

MONDAY: Mostly sunny. Highs 56-63. Wind NW 5-15 MPH.

DAYS 6-10 (OCTOBER 11-15)

High pressure over the region shifts to the south and east early to middle of next week with a moderating temperature trend. Next cold front follows after that, current timing late October 13 to early October 14, with a shower threat and a return to cool / dry weather for the end of the period.

DAYS 11-15 (OCTOBER 16-20)

Some up and down temperatures, tending to average near to below normal, with limited precipitation chances around air mass changes.

C-19 Chat Post – 10-6-2022

In what looks like a pattern a little more typical of springtime, but can sometimes happen in autumn too, low pressure sits south of our area and between it, and high pressure to the north, a persistent broad onshore flow continues today along with bands of rain with embedded heavier showers (maybe even some thunder especially to the south). This rainfall has been a little more expansive in coverage than I had anticipated it might be, but not continuous as there are breaks in it at times. However, there have already been some amounts of 2 inches or higher especially in the South Shore region of MA, and this gets added to today as the rest of the region adds some up as well. While you may be tired of a long stretch of cloudy and occasionally wet weather, this again has been generally beneficial to continue reducing the ongoing drought across most of the region. However if you are looking for some nicer weather, you’re going to see it as vastly improved conditions – fair and milder – take place Thursday into Friday as high pressure shifts quickly over then south of the region in the wake of the departed low. This low, the remains of what was once Hurricane Ian, will have produced a range of after effects from devastating damage in Florida to beneficial rainfall in New England. Don’t get too used to the mild spell, which will be brief. A cold front will whistle across the region from west to east late Friday, maybe producing a rain shower, but definitely opening the door for a chilly October air mass from Canada for our weekend. This will come along with mainly dry weather and a gusty breeze. A secondary cold front crossing the region later Sunday may bring a brief passing rain shower.

TODAY: Overcast with periods of rain and embedded heavier showers, including a possible thunderstorm. Areas of fog. Highs 53-60. Wind NE 5-15 MPH inland and 15-25 MPH coast with higher gusts possible.

TONIGHT: Mostly cloudy. Any rain ending. Lows 45-52. Wind N 10-20 MPH, diminishing overnight.

THURSDAY: Sun/cloud mix. Highs 66-73. Wind W to SW 5-15 MPH.

THURSDAY NIGHT: Partly cloudy. Lows 50-57. Wind SW 5-15 MPH.

FRIDAY: Partly sunny. A brief passing rain shower possible in the afternoon. Highs 68-75. Wind SW 10-20 MPH shifting to NW from west to east by day’s end.

FRIDAY NIGHT: Partly cloudy then clearing. Lows 38-45. Wind NW 10-20 MPH, higher gusts.

SATURDAY: Sun and passing clouds. Highs 53-60. Wind NW 10-20 MPH, higher gusts.

SATURDAY NIGHT: Clear. Areas of frost in sheltered lower elevations. Lows 37-44, possibly colder in sheltered lower elevations. Wind W 5-15 MPH, higher gusts, but may drop to near calm in sheltered lower elevations..

SUNDAY: Sunny morning. Partly sunny afternoon with a slight chance of a passing rain shower. Highs 56-63. Wind W 10-20 MPH shifting to NW late-day.

DAYS 6-10 (OCTOBER 10-14)

High pressure builds across the region early next week with fair weather and a chill, then moderating as the high center shifts offshore to the east. Warm front / cold front combo seems timed for the October 12-13 period when there may be brief light rain / rain showers and milder air, before another shot of chilly air from Canada to end the period.

DAYS 11-15 (OCTOBER 15-19)

Any warm-up will be brief as additional shots of chilly air await in Canada to move this way in a west northwesterly air flow with mostly dry weather. Brief precipitation episodes can accompany any air mass change.

C-19 Chat Post – 10-5-2022

Low pressure hangs around to our south while high pressure to the north weakens a little bit over the next 2 days. This will result in occasional rainfall favoring the South Coast, but possible elsewhere as well. Low pressure pulls away by Thursday and a narrow area of high pressure moves in, resulting in fair and milder weather which will last into Friday. This ends when a strong cold front sweeps through the region Friday evening, perhaps bringing a shower, but more notably bringing a much cooler air mass to start the weekend.

TODAY: Mostly cloudy. Periods of rain favoring the South Coast region. Highs 54-61. Wind NE 10-20 MPH except 15-25 MPH South Coast, higher gusts possible.

TONIGHT: Cloudy. Periods of rain eastern CT, RI, and eastern MA. Lows 46-53. Wind NE 10-20 MPH except 15-25 MPH coast, higher gusts.

WEDNESDAY: Cloudy. Periods of light rain eastern and southern MA, RI, eastern CT, diminishing later in the day. Highs 53-60. Wind NE 10-20 MPH except 15-25 MPH coast, higher gusts.

WEDNESDAY NIGHT: Mostly cloudy. Any rain ending. Lows 45-52. Wind N 10-20 MPH, diminishing overnight.

THURSDAY: Sun/cloud mix. Highs 66-73. Wind W to SW 5-15 MPH.

THURSDAY NIGHT: Partly cloudy. Lows 50-57. Wind SW 5-15 MPH.

FRIDAY: Partly sunny. Late-day showers possible southwestern NH and central MA. Highs 68-75. Wind SW 10-20 MPH.

FRIDAY NIGHT: Variably cloudy. Evening showers possible southeastern NH, eastern MA, RI, eastern CT. Lows 42-49. Wind shifting to NW 10-20 MPH, higher gusts.

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

DAYS 6-10 (OCTOBER 9-13)

General zonal flow pattern. Secondary cold front passes by later in the weekend (October 9) with a few clouds and another shot of chilly air as another Canadian high moves into the region for October 10-11, but as the high center slips to teh south we’ll see moderating temperatures later in the period with continued dry weather.

DAYS 11-15 (OCTOBER 14-18)

A return to mostly below normal temperatures quickly at mid month with another series of cold fronts and Canadian air masses set to visit. Precipitation generally below normal.

C-19 Chat Post – 10-3-2022

Over the weekend, many areas saw some wet weather Saturday and then the focus was windy weather Sunday, and temperatures ran below normal. With low pressure to our south, once associated with Ian, and high pressure to our north, this breezy, cool, and sometimes wet regime will continue for the first few days of this week, basically through Wednesday. Rain-free conditions will be dominant today as the high has a bit more control, but the low will exert more control over our weather later Tuesday and Wednesday when periods of mainly light rain will likely occur, with the greatest chance of this being in eastern and southern MA, RI, and eastern CT, as far as the WHW forecast area goes. The low pressure area finally pulls away by Thursday. At that time, a narrower extension of high pressure builds in for fair and milder weather both Thursday and most of Friday. Late Friday, especially Friday night, we’ll look for a strong cold front to cross the region from west to east with gusty wind and a possible shower.

TODAY: Lots of clouds / intervals of sun. Highs 55-62. Wind NE 5-15 MPH inland and 10-20 MPH coast with a few higher gusts especially Cape Cod.

TONIGHT: Partly to mostly cloudy. Lows 45-52. Wind NE 5-15 MPH inland and 10-20 MPH coast with a few higher gusts, again especially Cape Cod.

TUESDAY: Mostly cloudy. Periods of light rain by late-day Cape Cod and South Coast region. Highs 54-61. Wind NE 10-20 MPH except 15-25 MPH South Coast, higher gusts possible.

TUESDAY NIGHT: Cloudy. Periods of rain eastern CT, RI, and eastern MA. Lows 46-53. Wind NE 10-20 MPH except 15-25 MPH coast, higher gusts.

WEDNESDAY: Cloudy. Periods of light rain eastern and southern MA, RI, eastern CT. Highs 53-60. Wind NE 10-20 MPH except 15-25 MPH coast, higher gusts.

WEDNESDAY NIGHT: Mostly cloudy. Any rain ending. Lows 45-52. Wind N 10-20 MPH, diminishing overnight.

THURSDAY: Sun/cloud mix. Highs 66-73. Wind W to SW 5-15 MPH.

THURSDAY NIGHT: Partly cloudy. Lows 50-57. Wind SW 5-15 MPH.

FRIDAY: Partly sunny. Evening showers possible southwestern NH and central MA. Highs 68-75. Wind SW 10-20 MPH.

DAYS 6-10 (OCTOBER 8-12)

The aforementioned cold front (discussion above) will set up the region for a dry weekend October 8-9 with temperatures generally below normal, a gusty breeze Saturday settling down somewhat Sunday. A reinforcing cold front is expected to pass by sometime early next week keeping the pattern of mostly dry but below normal temperatures going into the middle of the month.

DAYS 11-15 (OCTOBER 13-17)

Overall pattern looks like it will be dominated by a northwesterly air flow from Canada with dry, cool weather much of the time, and a brief milder shot between cool pushes.

C-19 Chat Post – 10-3-2022

Yesterday it was more about the remnant rain from Ian, which did deliver over 1 inch for parts of the immediate South Coast, while much less fell elsewhere. Today, it’s more about the wind. The gradient between the elongating low that was once the hurricane and a stronger high pressure area to the north will create a blustery northeasterly wind in our region, along with lots of cloudiness and a continuation of below normal temperatures. Rainfall today though will be largely absent, limited to a spotty and very light around Cape Cod and the Islands for a while this morning. High pressure then gains ground tonight through early Tuesday, keeping us dry, but still cool as that low pressure area will remain to the south and we keep a generally northeasterly air flow, though lighter as the tighter gradient is displaced to the south. The western portion of the elongated low will consolidate into a renewed storm system that will make a bit of a run back to the north, definitely enough to increase the wind and cloud cover again heading through later Tuesday and Wednesday, and probably enough to clip at least Cape Cod with some additional rainfall. Finally, all of it should be out of here Tuesday as the upper pattern shifts to kick the low pressure area out to sea and allow high pressure to build in.

TODAY: Mostly cloudy with a few intervals of sun possible at times as well. Very light rain possible Cape Cod / Islands mainly during the morning. Highs 56-63. Wind NE 10-20 MPH, gusts up to 30 MPH near the coast.

TONIGHT: Mostly cloudy. Lows 47-54. Wind E 5-15 MPH, higher gusts.

MONDAY: Partly sunny. Highs 58-65. Wind NE 5-15 MPH.

MONDAY NIGHT: Mostly cloudy. Lows 46-53. Wind NE 5-15 MPH.

TUESDAY: Variably cloudy. Highs 56-63. Wind NE 5-15 MPH, higher gusts.

TUESDAY NIGHT: Mostly cloudy. Chance of rain Cape Cod / South Coast. Lows 46-53. Wind NE 5-15 MPH, higher gusts especially South Coast.

WEDNESDAY: Mostly cloudy with possible rain South Coast favoring Cape Cod. Partial sun elsewhere. Highs 57-64. Wind NE-N 10-20 MPH and gusty, probably somewhat stronger Cape Cod.

WEDNESDAY NIGHT: Partly cloudy. Lows 44-51. Wind NW 5-15 MPH.

THURSDAY: Sun/cloud mix. Highs 66-73. Wind SW 5-15 MPH.

DAYS 6-10 (OCTOBER 7-11)

Some late-week changes with a strong cold front approaching October 7, still mild but with a gusty breeze, maybe a passing shower by evening. Breezy and cool but dry weather over the October 8-9 weekend. A reinforcing cold front may bring a shot of even cooler air for October 10 before a milder rebound to end the period.

DAYS 11-15 (OCTOBER 12-16)

Only expecting one brief shower threat from a cold front mid period, preceded by fair and milder weather and followed by a cool shot.

C-19 Chat Post – 10-2-2022

The moisture shield far north of what remains of Ian will bring our area some wet weather this weekend, but the scope of that will depend on location. If you are south of I-90, you’re most likely to see rain for more time. If you’re near the South Coast, you’ll see the most rain for the most time. If you are to the north, you may see little or even possibly no rain. Certainly though there will not be much, if any, sunshine this weekend, and it will also be on the cool side due to a northeasterly air flow, initially weak today but strengthening on Sunday as the gradient tightens between Ian’s remaining low pressure to the south and a high pressure area to the north. This general set-up persists early next week, and I’ve been a little uncertain as to whether or not we’ll be more impacted by the low to the south or the high to the north, but right now I’m leaning toward the high pressure area being stronger to start the week, keeping the low to the south, then one final push of low pressure that may tag at least Cape Cod with a little wet weather later Tuesday and/or Wednesday. Need to keep an eye on that in fine-tune it later.

TODAY: Cloudy. Rain likely South Coast, periods of rain I-90 belt, chance of occasional very light to light rain to the north of the I-90 belt. Highs 56-63. Wind NE up to 10 MPH.

TONIGHT: Cloudy. Best chance of rain Cape Cod, lesser chance elsewhere. Areas of fog and drizzle favoring eastern coastal locations. Lows 46-53. Wind NE 5-15 MPH.

SUNDAY: Mostly cloudy. Light rain possible near the South Coast at times. Highs 56-63. Wind NE 10-20 MPH, gusts up to 30 MPH near the coast.

SUNDAY NIGHT: Mostly cloudy. Lows 47-54. Wind E 5-15 MPH, higher gusts.

MONDAY: Partly sunny. Highs 58-65. Wind NE 5-15 MPH.

MONDAY NIGHT: Mostly cloudy. Lows 46-53. Wind NE 5-15 MPH.

TUESDAY: Variably cloudy. Highs 56-63. Wind NE 5-15 MPH, higher gusts.

TUESDAY NIGHT: Mostly cloudy. Chance of rain Cape Cod / South Coast. Lows 46-53. Wind NE 5-15 MPH, higher gusts especially South Coast.

WEDNESDAY: Mostly cloudy with possible rain South Coast favoring Cape Cod. Partial sun elsewhere. Highs 57-64. Wind NE-N 10-20 MPH and gusty, probably somewhat stronger Cape Cod.

DAYS 6-10 (OCTOBER 6-10)

A small area of high pressure extends into the region with fair and seasonable to milder weather October 6 into October 7 before a strong cold front swings through with a shot of chilly air to follow for the October 8-9 weekend that may be reinforced at the end of the period from another Canadian cold front.

DAYS 11-15 (OCTOBER 11-15)

Overall pattern looks fairly dry with temperatures near to mostly below normal.

C-19 Chat Post – 10-1-2022

High pressure builds in today but then retreats slightly north this weekend. While this is occurring, Ian makes one more landfall as a hurricane (category 1) on the South Carolina coast today then moves north northwest into the mountains of North Carolina and Virginia where it weakens over the weekend. We’ve already experienced the high cloud shield from Ian for over 24 hours – it made for a very colorful sunset for some areas yesterday and a nice sunrise for some again this morning. The rainfall from that system is also spreading out and some of it will make a push toward our area for this weekend. The question for several days has been just how much impact, if any, that rain would have. Even when it became clear the low itself would not make the trip directly up this way, we always have to watch for the rain shield in this pattern as it can move quite a distance away from its parenting storm. Right now the best guess is that there will be the most rain right along the South Coast on Saturday, with a lesser chance that rain gets to and north of I-90, and if it does so it would be rather brief and lighter, before moving out. Either way, the cloud shield will be over the region much of the time the next few days, thin enough today that we have some filtered sunshine, but thicker so we have much less sun opportunity tomorrow (with the rain chance present) and maybe thinning out again at least to the north on Sunday. With a northeasterly air flow taking over between Ian’s remnant low and a big high to our north, we may eventually see some lower clouds from the ocean as well at some point during the weekend. Early next week we may still be on the fence as a hang-back low moves out south of our area, and may get close enough later Monday or Tuesday to bring some additional at least light rainfall in to parts of southeastern New England. All the while our temperatures will be running a little below normal as our cooler early autumn regime continues.

TODAY: Sun filtered through high clouds. Highs 58-65. Wind NE up to 10 MPH.

TONIGHT: Mostly cloudy. Lows 42-49. Wind NE up to 10 MPH.

SATURDAY: Mostly cloudy. Periods of rain South Coast and a lesser chance of rain in the I-90 belt. Highs 57-64. Wind NE up to 10 MPH.

SATURDAY NIGHT: Cloudy. Chance of rain near the South Coast. Lows 47-54. Wind NE 5-15 MPH.

SUNDAY: Mostly cloudy. Light rain possible near the South Coast at times. Highs 56-63. Wind NE 10-20 MPH, gusts up to 30 MPH near the coast.

SUNDAY NIGHT: Mostly cloudy. Lows 47-54. Wind E 5-15 MPH, higher gusts.

MONDAY: Partly sunny. Highs 58-65. Wind NE 5-15 MPH.

MONDAY NIGHT: Mostly cloudy. Chance of rain Cape Cod / South Coast. Lows 46-53. Wind NE 5-15 MPH.

TUESDAY: Cloudy. Chance of rain, favoring the South Coast / Cape Cod. Highs 56-63. Wind NE 5-15 MPH, higher gusts.

DAYS 6-10 (OCTOBER 5-9)

Improving weather middle of next week with clearing and a little milder. Strong cold front follows with a brief shower chance and a return to below normal temperatures after that.

DAYS 11-15 (OCTOBER 10-14)

Potential wet weather threat early period, then dry with near to below normal temperatures expected.

C-19 Chat Post – 9-29-2022

An upper level trough will swing through the region during the first half of the day today with a sun/cloud mix for a while mid to late morning as the sun-heated air rises into colder air aloft. I do not expect these clouds to grow enough to produce any showers as their development will be thwarted by the arrival of milder air aloft for the second half of the day. Also during the day today the South Coast region will see a stream of high clouds that once belonged to the outflow of Hurricane Ian, and even as high pressure builds into the region tonight and Friday, we will see more high clouds fanning into our sky that are associated with that system. The storm, which came ashore on the West Coast of Florida Wednesday as a category 4 hurricane, has pretty much completed crossing the peninsula and will emerge off the eastern coast of the state back over water before turning to the north and making another landfall on Friday as a strong tropical storm in South Carolina. While the storm’s impact will be far less severe than what Florida experienced, it will still be a formidable system capable of producing wind damage and flooding rain, as well as some minor to moderate storm surge. This system will then weaken but expand in coverage over the Southeast and Mid Atlantic. The northern edge of its rain shield will make a push toward our South Coast region by later Saturday, but for the most part I expect this system to remain to our south with protective high pressure in place over the weekend and Monday as well. We won’t escape its high cloud shield however, which will limit our sunshine during the day and our star gazing at night.

TODAY: Sun with passing clouds. Highs 63-70. Wind NW 5-15 MPH.

TONIGHT: Mostly clear. Lows 41-48. Wind N up to 10 MPH.

FRIDAY: Sun with high clouds. Highs 60-67. Wind NE up to 10 MPH.

FRIDAY NIGHT: Mostly cloudy. Lows 42-49. Wind NE up to 10 MPH.

SATURDAY: Limited sun, especially south of I-90. Highs 63-70. Wind variable up to 10 MPH.

SATURDAY NIGHT: Mostly cloudy. A touch of light rain possible South Coast. Lows 47-54. Wind NE 5-15 MPH.

SUNDAY: Mostly cloudy. A touch of rain possible near Cape Cod early in the day. Highs 58-65. Wind E 5-15 MPH, higher gusts especially near the coast.

SUNDAY NIGHT: Mostly cloudy. Lows 47-54. Wind E 5-15 MPH.

MONDAY: Partly sunny. Highs 58-65. Wind NE 5-15 MPH.

DAYS 6-10 (OCTOBER 4-8)

Low pressure to the south may get close enough to deliver a bit of light rain to southern areas at the start of the period. A cold front coming through mid to late period may bring a shower but more notably a shot of very cool, windy weather.

DAYS 11-15 (OCTOBER 9-13)

Potential wet weather threat early period, then dry with near to below normal temperatures expected.
