Tropical air is on a journey northward into New England and will continue to flood into the region through Thursday on a southerly wind. It will be quite warm on Wednesday even with just partial sunshine, but a cold front moving into the region on Thursday will bring showers, including a band or two of heavier rain and thunderstorms especially in the afternoon and evening. This will likely have some impact on the Patriots/Jets game in Foxboro.

By Friday, the wet weather and high humidity be pushing off to the northeast but around a very broad low pressure area there will still be mild air blowing into the region on a west southwest wind. The trend to cool will be a stair-step downward with 70s Friday, 60s Saturday, and 50s by Sunday as a series of troughs and fronts move through and winds gradually shifting more west to northwest by the end of the weekend when it will feel more like the end of October.

Early next week will be governed by high pressure and fair weather with cool to seasonable air.

I hope anybody that had today off was able to enjoy it around southeastern New England, despite the day turning more grey than I had forecast. This post does not carry major changes from the previous one, with still some warmer and more humid air on the way in during the next 2 days, and a front crossing the region Thursday with showers and possible thunderstorms. There remains some uncertainly about the weather late in the week as there are still some significant model differences, but for now still leaning toward a drying/cooling trend Friday through the weekend.

The new week starts for some of you while others will be enjoying an extra weekend day on Monday, Columbus Day, but now I’m confused, not about the setup of the week, but the weather that will occur therein. There is some significant disagreement in guidance in the configuration of the jet stream and the timing of weather systems. If you remember my last post, I had a system coming through on Wednesday with wet weather followed by some clearing, then lots of clouds Thursday and better weather Friday. I now am going to lean toward a timing that’s about 24 hours slower, so that fair weather and a warm-up that commences Monday will continue through Wednesday. The wet weather will then come through sometime Thursday with lots of clouds Friday and then fair weather next weekend. But this is lower than average confidence and it will be important to check for updates.

SOUTHEASTERN NEW ENGLAND FORECAST…
TONIGHT: Mostly clear. Patchy valley fog. Lows from 40 deep valleys to 50 coast/urban areas. Calm wind.
MONDAY – COLUMBUS DAY: Sunny to partly cloudy. Highs in the 60s. Wind S 5-15 MPH.
MONDAY NIGHT: Partly cloudy. Lows in the 50s. Wind S 5-15 MPH.
TUESDAY: Partly to mostly cloudy. Highs in the 70s. Wind S 10-20 MPH.
WEDNESDAY: Partly sunny. Low 55. High 75.
THURSDAY: Showers likely. Low 55. High 65.
FRIDAY: Variably cloudy. Low 48. High 62.
SATURDAY: Partly cloudy. Low 45. High 60.
SUNDAY: Mostly sunny. Low 44. High 64.

5:44PM original post
8:50AM Saturday time edit

The weekend is here! And if you are lucky enough to have a 3-day one for Columbus Day then a good portion of this weekend will feature weather that is likely favorable for your plans. The only interruption is the wet start as a wave of low pressure passes south of the region. The timing still looks similar, mainly a morning-midday event. However, it may take into late afternoon for rain to exit Cape Cod and the Islands, so if you are heading there, more patience is required. But that patience will be rewarded with fabulous weather Sunday and Monday not only there but in all locations as high pressure builds in Sunday then offshore Monday. This will allow for a warm up Monday after a crisp/cool Sunday. Whatever your plans, please have a safe weekend!

Looking ahead a little, the warm up that commences Monday will continue Tuesday, and it may get quite a bit warmer than average, depending on the amount of sunshine we have. For now, the forecast will remain unchanged from the previous post, but in the back of your mind you can make note that it may end up warmer than the 74 that is currently there (75-80 potential if enough sun). Still looking like a trough pushes east and sends a front into the region with a band of rain/thunderstorms sometime Wednesday. I believe it will be progressive enough that we may salvage part of Wednesday with some fair and mild weather. It should then turn cooler but not that chilly for later next week with clouds dominant on Thursday as an upper level trough swings through, and sunshine Friday as high pressure builds in. But again, these days are a ways off and there is plenty of time to work out those details.

SOUTHEASTERN NEW ENGLAND FORECAST…
SATURDAY: Cloudy with rain exiting from west to east late morning through early afternoon, from Boston north and west, lingering into later afternoon southeast of Boston especially Cape Cod and the Islands. Clearing northwest of Boston by day’s end. Highs upper 50s to middle 60s. Wind NE to N 5-15 MPH.
SATURDAY NIGHT: Clear. Lows upper 30s to middle 40s. Wind NW 5-15 MPH.
SUNDAY: Sunny. Highs 55-60. Wind NW 5-15 MPH.
MONDAY – COLUMBUS DAY: Partly cloudy. Low 39. High 66.
TUESDAY: Partly cloudy. Low 50. High 74.
WEDNESDAY: AM rain/thunderstorms, PM sun/clouds. Low 55. High 75.
THURSDAY: Variably cloudy. Low 45. High 65.
FRIDAY: Mostly sunny. Low 43. High 63.

5:55PM

No changes to previous discussion and forecast for this post other than to slow the onset of any precipitation from the low pressure wave passing to the south to overnight Friday night instead of late in the day Friday. Still expect whatever is passing by to be moving very rapidly and on the way out by morning or midday Saturday, again with the greatest chance of any rain occurring in southern MA and RI. Still looking for high pressure to move in Sunday with cool and dry weather, followed by a warm-up early next week. A trough from the west will send a band of rain into the region at some point next week, looking like Wednesday at this point. Timing will be fine tuned as we get closer to this event. Looking like an upper low hanging around Thursday with an unstable and cooler day expected.

SOUTHEASTERN NEW ENGLAND FORECAST…
TONIGHT: Few clouds interior MA and southern NH dissipate early while a deck of high clouds crosses the South Coast and Cape Cod. Clear elsewhere. Lows in the 40s except lower 50s urban centers. Diminishing W wind.

THURSDAY: Partly cloudy. Low 45. High 65.

3:52PM

Low pressure moving away in eastern Canada and a small high pressure area trying to build in will bring dry, breezy, and cooler weather through Thursday. A wave of low pressure passing south of the region later Friday to early Saturday will bring some cloudiness and a chance of rain mainly for RI and southern MA. High pressure builds in again later in the weekend then offshore early next week with fair weather, starting cool then followed by a warming trend.

The focus of this update, even though it will contain a full forecast, is the potential severe weather event for Wednesday morning. I will keep it short and to the point. As broad low pressure passes north of the region across southern Canada and a strengthening second low passes northwest of southern New England, its attendant cold front will swing through the region from west to east in the early to mid morning hours of Wednesday, bringing an area of rain including some embedded heavy showers and thunderstorms.

Time-frame: 3AM-9AM for entire event, though the heaviest rain and strongest wind will be relatively short-lived for any given area. Areas west of Boston from western into central MA and adjacent CT/VT/southwestern NH will see activity in the 3AM-6AM window of time, while eastern MA including the Boston area as well as RI and southeastern NH gets it closer to the 6AM-7AM time. Cape Cod and the Islands will be last to see the activity arrive and depart.

Severe? The risk of torrential rain for at least a brief period of time as high. This would disrupt travel and cause localized flooding. The risk of strong and gusty winds of the straight-line variety is moderate. The risk of a brief tornado is low but cannot be ruled out completely.

What happens after? Once the action is out of here Wednesday morning, the rest of the day will feature sun and passing clouds, drying air, and a gusty breeze, though it will still be mild through the daylight hours as a secondary trough, behind which is the cooler air, will not arrive until later in the day.

Between broad low pressure in eastern Canada and a small high pressure area to the south will be a gusty and cool westerly wind but a nice day for Thursday. Low pressure passing south of the region later Friday to early Saturday will bring some cloudiness and a threat of some rain to at least southern MA and RI. Not sure how far north this gets yet. But I do think it gets out of here for later Saturday and Sunday which will be dominated by high pressure and nice Autumn weather.

Still looks like a warm-up early next week, though the tropical threat looks less. More on this later.

SOUTHEASTERN NEW ENGLAND FORECAST
EVENING: Lots of clouds, partial moonshine as it rises in the east. A shower far west to northwest of Boston. Temperatures in the 60s. Wind S 10-20 MPH.
OVERNIGHT: Heavier clouds arrive from southwest to northeast. Rain and embedded thunderstorms arriving west to east after 2AM, heaviest activity west of Boston after 3AM and Boston area northward and southward by the 6AM hour (see details above). Lows around 60. Wind S to SW 5-15 MPH, higher gusts.
WEDNESDAY: Cloudy start with rain and embedded thunderstorms ending in eastern areas by mid morning. Sunshine and passing clouds mid morning on though lingering clouds/showers Cape Cod mid morning. Highs 65-70. Wind SW 10-20 MPH, strongest gusts, shifting to W.

SOUTHEASTERN NEW ENGLAND DISCUSSION…
As a large upper level low pressure continues to spin in east central Canada and the north central USA through the middle of the week, it will send some action our way in the form of developing surface low pressure over the Ohio Valley Tuesday. This low will intensify fairly quickly and move northeastward into the St. Lawrence Valley by Tuesday night then northward deeper into Canada by Wednesday. Its broadening circulation will first send a batch of mild and more humid air into southern New England on Tuesday as a weak warm front moves through during the morning and midday. A few showers may occur with this, but otherwise it will just send lots of clouds through the region. A few bands of showers will form well northwest of Boston during the day but it looks like this activity will never make it further east than southwestern NH and north central MA before it dissipates. The main push of wet weather that is destined for southeastern New England is going to be from an occluded front trailing from the parent low pressure area. This front will swing through the region in the pre-dawn to shortly-after-dawn hours of Wednesday, and will be accompanied by a band of rain and possible thunderstorms, and potentially strong wind gusts. This will be watched as it gets closer to occurring. Once this area crosses, it will be followed by gusty west winds, drying but still mild air during the day, a mix of clouds and sun, and a slight risk of a passing additional shower. By Wednesday evening, it will turn significantly cooler behind a trailing trough. Cool and dry weather is expected Thursday along with a gusty breeze as the broad low pressure area continues to push across southeastern Canada. Friday, a small wave of low pressure will bring more cloudiness and the chance for some light rain, depending on its track. This should move right along and evacuate the region in time for high pressure to move in for the weekend, which looks nice. By the start of next week, this high should be shifting offshore and a warm-up will be underway.

SNE DISCUSSION…
Some media will probably still try to play up the “big vortex” dominating the weather in the US this coming week. While it’s true that a fairly strong closed-off low pressure area will be the rule, and some of its weather includes early frozen precipitation and cold air (mainly central USA), what it will serve to do for the Northeast is keep the pattern on the mild side, with 2 disturbances passing by, one early Wednesday and another late Friday. Shower threats will exist in advance of and with the passage of each of these (late Tuesday to early Wednesday and again during Friday and Friday night, based on current timing). By the weekend, the closed low will have weakened and lifted northeastward into Canada, being replaced by a strong west-to-east jet stream. By early the following week, things may get a little more interesting once again as the overall pattern will be mild and a little wetter, and with a potential threat from the tropics. Long way off – no worries now. That will be addressed in due time.

SNE FORECAST…
TONIGHT: Clear. Patchy frost far inland valleys. Lows in the 30s inland valleys, 40s elsewhere but around 50 immediate shore and urban areas. Wind W dropping to under 10 MPH, calm in some valleys.

SOUTHEASTERN NEW ENGLAND DISCUSSION…
No big changes to this forecast other than to slow the timing down of the wet weather system for next week a little. Onshore flow continues today but with sun, especially inland, though ocean clouds win the battle late in the day after flirting with the coastline most of the day. By tonight and Saturday, it’s overcast as low pressure approaches from the west, but its rain will first arrive well to the west and hold off from reaching the eastern areas until late in the day and evening. Some drizzle and areas of fog may occur before that due to low level moisture from the ocean. The cold front from the west clears the whole mess outta here by Sunday morning and Sunday will be a great Fall day. Nice weather with a warming trend for next week as the flow turns southwest. Another front crosses the region Wednesday with showers.

SOUTHEASTERN NEW ENGLAND FORECAST…
TODAY: Sun inland, clouds/sun coast, then clouds advancing inland late. Highs from near 60 coast to near 65 inland. Wind NE up to 10 MPH.
TONIGHT: Cloudy. Areas of fog and drizzle overnight. Lows in the 50s. Wind light E.
SATURDAY: Cloudy. Areas of fog and drizzle. A band of rain arriving from west to east late afternoon into the night with a slight risk of embedded thunderstorms. Highs in the 60s. Wind SE 5-15 MPH increasing to 10-20 MPH with higher gusts late.
SUNDAY: Mostly sunny. Low 50. High 60.
MONDAY: Partly cloudy. Low 45. High 65.
TUESDAY: Partly sunny. Low 55. High 70.
WEDNESDAY: Mostly cloudy. Chance of showers. Low 55. High 65.
THURSDAY: Partly cloudy. Low 45. High 60.

SOUTHEASTERN NEW ENGLAND DISCUSSION…
A few days ago, it looked like “a few showers”. But in reality, for at least parts of southern New England, it evolved into a somewhat beneficial rain, all due to low pressure spinning offshore. It’s not a strong storm, but this interaction of upper level energy, surface low pressure, and moisture has delivered some wet weather, not nearly enough to break the minor to moderate drought but helpful to that end. What would be better is more regular rain events. We’ll have some of that, as the overall pattern is evolving to feature a significant trough of low pressure in the Midwest, putting the East Coast including New England on the east side of it, often in an upper level southwesterly flow, combining moisture from the south with disturbances from the west. One such system will cross the region this coming weekend, with another threat early next week. Right now, the former looks more significant and the latter a little less productive. Though some chilly shots of air will be diving out of Canada into the central US in this upcoming pattern, it’s not a particularly chilly pattern for New England, as cool air masses arriving behind departing low pressure systems are often modified by a long trip over a landmass holding leftover Summer warmth.

SOUTHEASTERN NEW ENGLAND FORECAST…
OVERNIGHT: Overcast. Rain likely. Lows in the 50s. Wind NE to N 10-20 MPH.
THURSDAY: Cloudy with rain becoming spotty and diminishing north to south during the morning. Breaking clouds in the afternoon. Highs in the 60s. Wind N 10-20 MPH.

FRIDAY: Sunshine but increasing high clouds late day. Highs in the 60s. Wind E 5-15 MPH.
SATURDAY: Cloudy. Patchy fog and drizzle with a chance of light rain morning and midday. Showers developing from west to east afternoon and evening. Rain and a chance of thunderstorms at night followed by rapid clearing southwest to northeast overnight. Low 56. High 68.
SUNDAY: Mostly sunny. Low 52. High 65.
MONDAY: Partly cloudy. Low 53. High 71.

SOUTHEASTERN NEW ENGLAND DISCUSSION…

Post ridge, post cold front, now we have upper level low pressure sitting near to just southeast of New England and an associated surface low as well. Enough moisture is also present to result in periods of rain especially over southern and eastern portions of the WHW forecast area, which has developed today on the final day of September, and will continue tomorrow, the first day of October. By Thursday, low pressure will start to pull away and we’ll trend drier. A sliver of sunshine is expected on Friday between the departing low and another approaching trough from the west. This approaching trough will result in a wet day on Saturday with more beneficial rain possible. These few rain events will put a small dent in the developing drought conditions over southeastern New England, though they won’t even come close to putting an end to it.

After a drying trend Sunday into Monday, another system from the west brings a chance of showers by Tuesday of next week.

SOUTHEASTERN NEW ENGLAND FORECAST…

THROUGH WEDNESDAY: Cloudy with periods of rain and areas of fog. Temperatures ranging from the upper 50s to middle 60s. Wind NE 5-15 MPH increasing to 10-20 MPH with higher gusts especially along the coast by Wednesday afternoon.

WEDNESDAY NIGHT: Rain ends, clouds remain. Lows 50-55. Wind N 10-20 MPH.

THURSDAY: Clouds break but limited sun at best. Highs in the 60s. Wind N 5-15 MPH.

FRIDAY: Mostly sunny. Low 48. High 66.

DISCUSSION…

The big high pressure ridge that provided the Summery weekend is now a memory and after the cold front that passed from the north Monday, a more onshore flow will dominate southern New England into midweek before turning more southerly later this week.  Less sun and warmth, more clouds but not much wet weather will be the ruling factors. But by Saturday, a trough of low pressure from the west will bring the first shot at widespread beneficial rain in a while, then continue eastward so that the second half of the weekend should be salvaged for outdoor activities.

SOUTHEASTERN NEW ENGLAND FORECAST…

TONIGHT: Cloudy. Patchy fog and drizzle. Lows 55-60. Wind NE 5-15 MPH.

TUESDAY: Mostly cloudy though a little partial sun is possible west of  Boston during the afternoon. Patchy fog and drizzle. Chance of light rain morning and midday mainly southeast of Boston. Highs in the 60s. Wind NE to E 5-15 MPH.

TUESDAY NIGHT: Mostly cloudy. Patchy drizzle and fog. Isolated showers possible. Lows 55-60. Wind light E.

WEDNESDAY: Cloudy. Areas of drizzle. Chance of light rain. Highs in the 60s. Wind E to SE.

THURSDAY: Partly sunny. Low 52. High 68.

FRIDAY: Variably cloudy. Low 53. High 66.

SATURDAY: Cloudy. PM showers likely. Low 55. High 66.

SUNDAY: Clearing. Low 51. High 63.

MONDAY: Sunny. Low 48. High 64.

5:31PM

DISCUSSION…

The first weekend of Autumn was more like Summer than some of the weekends during the actual Summer, featuring 100% sunshine with high temperatures well into the 80s in many areas. The big ridge of high pressure responsible for this weather is weakening and sinking to the south and will allow a cold front to push through southeastern New England from north to south Monday, bringing some increase in clouds and a turn to cooler air. Then a more onshore flow will be dominant Tuesday through midweek with weak upper level low pressure overhead. This will result in clouds being dominant and temperatures on the cooler side, though not too chilly. By late week, a more southerly flow is expected ahead of an approaching trough from the west, so that by next weekend at least some wet weather is probable.

SOUTHEASTERN NEW ENGLAND FORECAST…

TONIGHT: Mostly clear. Lows 50-55 inland valleys, 55-60 elsewhere. Light wind.

MONDAY: Partly cloudy. Highs 75-80 by early afternoon then cooling later in the day. Wind light variable becoming NE 10-20 MPH from north to south midday and afternoon.

MONDAY NIGHT: Partly to mostly cloudy. Patchy drizzle and fog overnight. Lows 55-60. Wind NE 5-15 MPH.

TUESDAY: Mostly cloudy. Patchy drizzle and fog. Highs 60-65. Wind E 5-15 MPH.

WEDNESDAY: Mostly cloudy. Low 50. High 65.

THURSDAY: Partly sunny. Low 53. High 67.

FRIDAY: Variably cloudy. Low 51. High 66.

SATURDAY: Mostly cloudy. PM showers likely. Low 54. High 66.

SUNDAY: Partly sunny. AM showers possible. Low 50. High 65.

3:25PM

High pressure at the surface and aloft will sit over New England this weekend, creating clear and warm weather but without humidity – perfect for outdoor activities whether you are indulging in early Autumn traditions or still trying to hang onto Summer as long as you can.

By Monday, we’ll still be in the warm airmass but a cold front will be approaching from the north and may toss some clouds into the region and not allow it to get as warm as the previous 2 days in most locations. This front will settle south of the region for the final day of September and the first day of October (Tuesday-Wednesday) with lots of clouds and somewhat cooler air, though not that chilly. The front is expected to try to creep back northward as a warm front on Thursday but the weather next week is a little suspect with that front trying to come by and possible low pressure trying to form to the southeast of New England while a new high builds north of the region. So the late-week part of the forecast will carry less confidence than usual at this time.

SOUTHEASTERN NEW ENGLAND FORECAST…

TONIGHT: Clear. Lows 40s interior valleys, 50s elsewhere. Wind light variable.
