Autumn officially begins Tuesday evening, but it’s going to feel like it all week, and the end of the week could get stormy.

Temperatures will be below normal this week. Image provided by WeatherBell.

A large area of high pressure slowly builds in and slides eastward across Canada over next few days, controlling our weather. The front that brought us some rain yesterday stalls out to the south, and waves of low pressure will ride along it at times between today and Thursday. This will bring in plenty of clouds at times, with a few showers possible near the South Coast at times, while inland areas see some sunny breaks. With persistent northeast to east winds and plenty of cloudcover, temperatures will remain on the cool side.

High pressure to the north controls out weather into mid-week. Loop provided by Tropical Tidbits.

The end of the week is where things get complicated. Low pressure will develop off the Southeast coast, as an upper-level disturbance moves in. It will get caught under the developing upper-level low and drift northward while intensifying. Beyond that, there are significant differences in the models about how strong the system gets and where it tracks, which obviously have big implications for the forecast. Some models have the storm impact our region as early as Friday morning, others wait until Saturday. Some have it start to move out by Saturday, some have it linger into next week. Some have it stay offshore, some bring it into Long Island or even farther inland. It’s WAY too early to even try to figure out what impacts this system might have and when. We are fairly sure that the persistent easterly fetch, combined with astronomical high tides this weekend, will almost certainly lead to some coastal flooding and very rough conditions offshore. The gradient between the strengthening high to the north and developing low to the south will likely result in windy conditions, especially offshore and right along the coast. We’ll likely write a separate blog post about this system, if it continues to look like a threat, towards midweek.

The models all have different ideas about a late-week storm. Images provided by Pivotal Weather.

Monday: Areas of morning fog, otherwise intervals of clouds and sun, breezy. High 61-68.

Monday night: Partly to mostly cloudy. Low 48-55.

Tuesday: Partly sunny, breezy. High 57-64.

Tuesday night: Partly to mostly cloudy. Low 44-51.

Wednesday: Partly sunny, windy. High 58-65.

Wednesday night: Partly cloudy. Low 43-50, a little milder across southeastern Massachusetts.

Thursday: Becoming mostly cloudy, windy, chance for late-day showers, favoring Cape Cod and southeastern Massachusetts. High 57-64.

Thursday night: Plenty of clouds, windy, showers possible, mainly south of the Mass Pike. Low 47-54.

Friday: Mostly cloudy, very windy, especially near the coast., chance of rain. High 56-63.

Saturday: Lots of clouds, very windy, especially near the coast, more rain possible. High 56-63.

Sunday: Partly to mostly cloudy, breezy, more showers possible. High 57-64.

Some cooler weather is on the way this weekend along with some rain.

Temperatures will be below normal this weekend. Image provided by weathermodels.com

A cold front will move across the region tonight with some showers accompanying it, though most of them should be done before midnight. High pressure builds in for Friday with developing sunshine and mild temperatures. A rather chilly night is expected Friday night with clear skies and light winds, though some clouds overnight may keep temperatures from dropping too much, Saturday will be much cooler, as east to northeast winds around the high bring cooler air in from the Atlantic. Clouds start to move back in Saturday night as another system heads our way. The models have had differing ideas with this system for a few days now, but they are finally starting to come together, but there are still some differences to work out. Some models have showers move in during the morning with steadier rain by early afternoon, while more of them keep the morning dry with the large high pressure area over eastern Canada still influencing our weather, with showers developing during the afternoon or evening, and steadier rain late in the day and into the night. We’re leaning towards the latter scenario. If you’re heading to the Patriots home opener on Sunday in Foxborough, we’re cautiously optimistic that much of the game should be dry with only a few showers around, but are aware of the possibility that it could be wetter. Rain should end early Monday, though showers may linger near the South Coast into part of the day, but high pressure will be building back in from the north with some drier air, especially north of Boston.

Will the rain arrive before kickoff on Sunday? Some models say yes, some don’t. Images provided by Pivotal Weather.

Thursday night: Showers ending, skies start to clear out late at night. Low 61-68.

Friday: Becoming partly to mostly sunny. High 72-79.

Friday night: Clear during the evening, becoming partly cloudy overnight. Low 44-51, a little milder in urban areas and right along the coast.

Saturday: A mix of sun and clouds, cooler. High 61-68.

Saturday night: Increasing clouds. Low 46-53.

Sunday: Mostly cloudy, showers developing from west to east during the afternoon. High 59-66.

Sunday night: Periods of rain, tapering off late at night. Low 49-56.

Monday: Lingering showers near the South Coast in the morning, becoming partly sunny during the afternoon, especially north of the Mass Pike, breezy. High 61-68.

As we head down the home stretch of summer, a rather nice week is expected across the region.

High temperatures should be in the lower to middle 70s in mid September. Image provided by weathermodels.com.

The last full week of astronomical summer is upon us, and while signs of fall are starting to pop up everywhere – a few leaves starting to change color, the Patriots have started their season, the Bruins open training camp this week, pumpkin-flavored everything has invaded – much of this week will still feel like later summer. Astronomical fall actually begins next Tuesday, September 22, at 8:05pm with the Autumnal Equinox. For this week, we’ve got high pressure in control through at least Wednesday after a cold front pushes offshore this morning. That front may produce a few showers early today, otherwise we’re looking at plenty of sunshine for the next few days. Temperatures will be a little cool into Tuesday, but as the high moves offshore, a warmup begins. A weak system moves through on Thursday with a few late-day showers, then high pressure returns for Friday and Saturday. Another system may bring in some additional showers late Saturday into Sunday morning, but for now, we’re cautiously optimistic that it will be dry by the time the Patriots home opener kicks off at 1:00pm.

Some, but not all, of the models show dry weather for kickoff of the Patriots home opener on Sunday. Images provided by Pivotal Weather.

Monday: Morning clouds, a shower or two, then becoming sunny and breezy. High 69-76.

Monday night: Clear skies, diminishing winds. Low 44-51, mildest in urban areas and right along the coast.

Tuesday: Sunshine and a few clouds. High 64-71.

Tuesday night: Clear to partly cloudy. Low 48-55.

Wednesday: Mostly sunny. High 73-80, cooler near the South Coast and Cape Cod.

Wednesday night: Partly cloudy. Low 57-64.

Thursday: Partly sunny, a late-day shower is possible. High 73-80.

Thursday night: Partly to mostly cloudy, chance for a few showers during the evening. Low 59-66.

Friday: A mix of sun and clouds. High 71-78.

Saturday: Partly sunny, showers possible late in the day and at night. High 66-73.

Sunday: Showers end in the morning, some sunny breaks develop in the afternoon. High 66-73.

Once again, we’re looking at a weekend that is mostly, but not completely, dry and mild.

Saturday morning could be on the cool side. Image provided by weathermodels.com.

High pressure settles in with drier and cooler weather tonight, lasting into a good portion of Saturday. Some clouds may hang around tonight with a wave of low pressure running along an offshore frontal system. Friday will be a Chamber of Commerce type day with sunshine, seasonably mild temperatures, and low humidity. With clear skies and light winds, Friday night will be cool, with some places likely dropping into the 40s by daybreak. Saturday will start off with some sunshine, but we’ll see clouds start to stream in during the afternoon ahead a low pressure system heading our way. Some showers are likely Saturday night into Sunday morning, ending from west to east by early afternoon. There is the potential for some heavy downpours, especially during the overnight hours, mostly likely near the South Coast. We’ll clear out at night, then high pressure builds in with sunshine and mild temperatures again on Monday.

Saturday night and early Sunday are looking wet right now. Images provided by Pivotal Weather.

Thursday night: Clear to partly cloudy. Low 56-63.

Friday: Sunshine and a few clouds. High 71-78.

Friday night: Clear and cool. Low 48-55.

We’ve got some nice weather for Labor Day, but things will go downhill later this week.

Temperatures will be above normal for most of the week. Image provided by WeatherBell.

Upper-level low pressure continues to pull away today with high pressure building in, giving us some very nice weather for Labor Day. Sunshine with a few clouds and seasonably mild temperatures are expected, with similar conditions on Tuesday, though it’ll be a few degrees warmer. By Wednesday, we’ll see some clouds moving in as a frontal system begins dropping down from the north. A couple of upper-level disturbances will move through, bring us some episodes of showers between late Wednesday and early Friday. These waves will lift the front northward, allowing milder air to return. We could see some gusty winds with the second disturbance on Thursday. High pressure returns later Friday into the weekend with drier and cooler conditions.

Most of the models do not show much rain between Wednesday and Friday.

Monday: Sunshine and a few afternoon clouds. High 72-79.

Monday night: Clear skies during the evening, becoming partly cloudy overnight. Low 54-61.

Tuesday: A mix of sun and clouds. High 74-81.

Tuesday night: Partly cloudy. Low 55-62.

Wednesday: Some morning sun, then becoming mostly cloudy and breezy late in the day with a chance for a few showers by evening. High 73-80.

Wednesday night: Lots of clouds with showers likely, breezy. Low 64-71.

Thursday: More clouds than sunshine, breezy, chance for more showers, especially during the afternoon. High 77-84.

Thursday night: Showers ending, some late-night clearing. Low 56-63.

Friday: Becoming partly to mostly sunny. High 70-77.

Saturday: A mix of sun and clouds. High 70-77.

Sunday: Partly sunny. High 76-83.

Labor Day weekend has arrived – the unofficial end of summer, and at least one or two days will feel more like early fall.

Temperatures are normally in the middle to upper 70s in early September. Image provided by weathermodels.com

A cold front pushes through the region this evening, with any lingering showers ending, followed by some clear overnight. High pressure then builds in at the surface, but an upper-level low will take it’s time crossing the Northeast. The result will be morning sun, afternoon clouds, and a few pop-up showers on Friday, perhaps a few more on Saturday. A storm system south of Nova Scotia may send a few more clouds in late Saturday and Saturday night, but any rainfall should stay well to our east. With the upper low overhead, temperatures will be relatively cool on Saturday and Sunday, but will start to moderate for Monday with drier air as the upper-low slides off to the east.

Thursday night: Showers end in the evening, some late night clearing. Low 60-67.

Friday: Becoming partly to mostly sunny in the morning, clouds return in the afternoon with a passing shower possible. High 77-84.

Friday night: Mostly clear. Low 58-65.

Saturday: Partly sunny, a few showers or a thunderstorm in the afternoon. High 69-76.

Saturday night: Partly to mostly cloudy. Low 52-59.

Sunday night: Clear skies. Low 51-58.

Labor Day: Sunshine and a few afternoon clouds. High 71-78.

“Summer’s going fast, night’s growing colder“

Rush wrote that lyric in the song “Time Stand Still”, but it’s appropriate for where we are now, as some cooler weather is on the way as we flip the calendar to September and the beginning of meteorological autumn.

Temperatures will be below normal for much of this week. Image provided by WeatherBell.

A backdoor cold front will drop southward today, likely stalling out just south and west of the region. The front will be accompanied by just a few clouds, but behind it, cooler air will settle in, especially near the east coast. A couple of waves of low pressure will ride along the front, keeping lots of clouds in place with some episodes of showers and a few thunderstorms at times between Monday night and Thursday. The last wave will lift the front northward as a warm front on Thursday, before a stronger cold front moves through late in the day, with some additional showers and thunderstorms. High pressure then builds in at the surface, but an upper-level low will settle into the Northeast for Friday and Saturday, possibly Sunday as well. The result will be sunshine each morning, some clouds build up, and a few spotty showers developing. For Labor Day, high pressure should result in dry and seasonably mild weather.

Several episodes of showers and thunderstorms are likely over the next few days. Loop provided by Weathermodels.com

Monday: A mix of sun and clouds. High 75-82, cooler near the east coast, especially in the afternoon.

Monday night: Becoming mostly cloudy, showers developing. Low 60-67.

Tuesday: Cloudy with some showers and thunderstorms likely, mostly in the morning. High 68-75.

Tuesday night: Plenty of clouds with a few showers. Low 57-64.

Wednesday: Partly to mostly cloudy, showers and thunderstorms likely, mostly in the afternoon. High 68-75.

Wednesday night: Cloudy with more showers and thunderstorms. Low 59-66.

Thursday: Intervals of clouds and sun with another round of showers and thunderstorms expected. High 75-82.

Thursday night: Showers and storms end in the evening, becoming partly cloudy overnight. Low 60-67.

Friday: Partly sunny, chance for a shower or thunderstorm. High 72-79.

Saturday: Intervals of sun and clouds, a shower or thunderstorm possible in the afternoon. High 68-75.

Sunday: A mix of sun and clouds, chance for an afternoon shower or thunderstorm. High 69-76.

Labor Day: Partly to mostly sunny. High 73-80.

The last 4 days of meteorological summer are upon us, and for the most part they’ll be good.

For parts of eastern New England, this has been one of the warmest summers on record. Image provided by the Southeast Regional Climate Center.

A frontal system will slowly move across the region over the next 24 hours. This system will produce showers and thunderstorms to our west through the evening, some of which could be strong to severe, but only a few widely scattered showers are expected across our area overnight. On Friday, we’ll see a few more showers and thunderstorms during the afternoon, but the bulk of the day should be dry. High pressure then builds in for the weekend with drier and seasonably warm conditions. As we get into Monday, a backdoor cold front will start dropping southward. Temperatures will depend on how quickly the front moves in, but only a few showers will accompany it, so most of the day should remain dry.

Temperatures will remain a little above normal for the next few days. Image provided by weathermodels.com

Thursday night: Partly to mostly cloudy with some widely scattered showers and areas of patchy fog. Low 64-71.

Friday: Partly sunny, a few showers and thunderstorms likely, mostly in the afternoon. High 78-85.

Friday night: Showers and storms end in the evening, becoming partly cloudy. Low 56-63.

Saturday: Partly to mostly sunny. High 74-81.

Saturday night: Clear to partly cloudy. Low 57-64.

Sunday: Sunshine and some afternoon clouds. High 78-85.

Sunday night: Partly cloudy. Low 61-68.

Monday: Intervals of clouds and sun with some showers likely. High 75-82.

Some unsettled weather is expected at times for the last full week of meteorological summer.

Temperatures will be a little below normal this week, especially across the interior. Image provided by WeatherBell.

The frontal system that brought us some showers over the past few days is finally pulling away, but an upper level low remains in place across southeastern Canada. This will generate some clouds and a few showers this afternoon, mainly north and west of Boston. Tuesday looks to be similar, though shower coverage will be a little less, as the upper low slowly starts to move away. High pressure builds in with drier weather for Wednesday into part of Thursday. Low pressure moving into southeastern Canada sends a warm front our way, with some showers during the afternoon and evening. A cold front trailing the system brings in more showers on Friday, then high pressure starts to build in for the weekend. Another upper-level low moves into southeastern Canada by late in the weekend, and a disturbance rotating around it may bring in a shower or two on Sunday.

An upper-level low will trigger some afternoon showers across the Northeast during the next few afternoons. Loop provided by weathermodels.com

Monday: For burns off revealing some morning sun, then some clouds develop with a few afternoon showers, mainly north and west of Boston, breezy. High 76-83.

Monday night: Mostly clear. Low 56-63.

Tuesday: Sunshine and some afternoon clouds, chance for a shower or two. High 74-81.

Tuesday night: Clear skies. Low 57-64.

Wednesday: A mix of sun and clouds. High 76-83.

Wednesday night: Partly cloudy. Low 59-66.

Thursday: Partly sunny, breezy, chance for some late-day showers or thunderstorms. High 78-85.

Thursday night: Partly to mostly cloudy, showers likely. Low 63-70.

Friday: Partly sunny, a few lingering showers in the morning across southeastern Massachusetts, then more showers during the afternoon. High 78-85.

Saturday: A mix of sun and clouds. High 76-83.

Sunday: Partly sunny, chance for an afternoon shower. High 76-83.

Some rain is on the way for parts of the weekend, but it won’t be a washout.

Episodes of showers and dry periods are likely through the weekend. Loop provided by weathermodels.com

A cold front will move across the region this evening and then stall out just to the south, controlling our weather for the next few days. Showers shower taper off this evening as the front settles south, but may continue across parts of the South Coast and Cape Cod into the night. High pressure will try to build in from the north on Friday with some drier air, but a wave of low pressure riding along the front to our south may bring in another period of showers to parts of Rhode Island and southeastern Massachusetts. As we get into the weekend, an upper-level low pressure area will settle into southeastern Canada. Disturbances rotating around it may help trigger additional waves of low pressure riding along the front. Another batch of showers will likely accompany one of those waves late Saturday and Saturday night. Sunday looks to be a day with some sun and occasional showers. Keep an eye to the sky (or radar) if you have outdoor plans. Much of the day should remain dry, but there will be some showers around. By Monday, high pressure starts building back in, but with the upper low nearby we’ll still have some clouds and maybe a shower or two.

Some heavier rainfall totals are possible south of Boston this weekend. Images provided by Pivotal Weather.

Thursday night: Plenty of clouds, some showers during the evening, possibly lingering into the overnight near the South Coast and Cape Cod. Low 59-66.

Friday: Some sunshine from the Merrimack Valley into southern New Hampshire, lots of clouds elsewhere, chance for a few showers across southeastern Massachusetts and Cape Cod. High 71-78.

Friday night: Mostly cloudy, chance for a shower or two across Cape Cod. Low 58-65.

Saturday: Plenty of clouds, showers likely, especially during the afternoon, mainly south of Boston. High 69-76.

Saturday night: Cloudy with more showers. Low 60-67.

Sunday: Clouds and some sunny breaks, some occasional showers possible. High 74-81.

Sunday night: Showers taper off in the evening, becoming partly cloudy. Low 60-67.

Monday: A mix of sun and clouds, chance for an afternoon shower. High 76-83.
