We have our first hurricane of the season, and it will indirectly impact part of the upcoming weekend around here.

Sunday morning could be another chilly one. Image provided by weathermodels.com

A cold front continues to push offshore and high pressure builds in this evening, remaining in control into Saturday. With an upper-level low nearby, we’ll see some clouds and possibly a shower or two on Friday, but most of them should stay well to our north. As the high moves overhead Saturday night we’ll have clear skies and diminishing winds, setting up another radiational cooling night, though some high clouds may interrupt to keep things a bit milder. If we stay clear, many places could again dip into the 30s by Sunday morning, with frost possible once again. As the high slides eastward on Sunday, clouds will start to stream in from the south and west ahead of what’s left of Hurricane Isaias (more on that in a moment). What’s left of the system will pass south of the region Sunday night and early Monday, spreading rain in by late Sunday afternoon or evening. Some of the rain could be heavy near the South Coast, but for most of us just a steady light rain is expected. Everything winds down Monday morning as the system pulls away, with dry weather for the afternoon, possibly even a few sunny breaks.

Before this year, we’d never gone past September 11 without a hurricane during the satellite era (since 1960). This year, it took until October 7, but we finally have our first hurricane of the season – Isaias. As of 2pm Thursday, it was centered about 350 miles south of the mouth of the Mississippi River, moving toward the east-northeast at 10 mph. Maximum sustained winds have increased to 85 mph, and additional strengthening is expected. Tropical Storm, Hurricane, and Storm Surge Warnings are in effect for parts of the Gulf Coast from Louisiana to the Florida Panhandle. Isaias is over some very warm water, but wind shear is starting to increase a little. It could continue to strengthen for the next 12-24 hours, possibly reaching category 3 strength, However, as it nears the coastline, wind shear will rapidly increase, with significant weakening likely before landfall. The storm may still be a hurricane at landfall, likely near Pensacola, Florida Friday night, but it should rapidly weaken once inland. The main threats will be flooding from heavy rain inland and storm surge along the coast, and some wind damage, likely confined to coastal areas.

We started last week with a lot of rain, but this week, rain will be hard to come by.

High temperatures should be in the middle 60s in early October. Image provided by weathermodels.com

We start the week off with a relatively mild day, but a cold front will cross the region this morning, accompanied by a just a few clouds. Behind it, northwest winds will bring some much cooler air in. High pressure brings lots of sunshine on Tuesday, but it will remain breezy and cool, with many locations struggling to get to 60. Clear skies and diminishing winds will result in a rather chilly night Tuesday night, with some frost possible by Wednesday morning in some spots. As the high slides eastward, we will see temperatures moderate a bit on Wednesday as winds start to pick up out of the southwest. Another cold front moves through on Thursday, accompanied by some clouds and possibly a shower or two, then high pressure returns with cooler weather for Friday and Saturday. Clouds start to move back in on Sunday as the next system begins to approach the region.

October has arrived, which means that 2026 is now 3/4 over. October can be an interesting month. We’ve had snow before, but we’ve also hit 90. Over average high temperatures start the month in the upper 60s, and end the month in the upper 50s. Most locations in our area will see their first frost during October in most years (possibly even next week). Of course, October is also one of the best months of the year if you’re a sports fan.

Will Friday be the last 80-degree day of the year for much of the region? Image provided by Forecast Eagle.

A cold front will head towards the region on Friday. Ahead of, we will see some sunshine in the morning, but it will be a breezy and mild day, with many places getting close to or over 80 degrees, likely for the last time in 2026. The front moves through in the evening, accompanied by a few showers, then high pressure builds in with sunshine and cooler air for Saturday. With clear skies and light winds, Saturday night will likely be on the chilly side. Sunday is a bit of a question mark at this point. That cold front will be stalled out well south of us, and a wave of low pressure will ride along it. Most of the models keep the rainfall associated with the system too far south to impact us, but not all of them. Could there be a period of showers near the South Coast late Sunday and Sunday night? It’s possible, but we’re not sure it’s likely at this point. Another cold front moves through on Monday. Ahead of it, it’ll be another mild day, with some places possibly reaching 70. Behind it, some rather chilly air will settle in. We’ll delve deeper into that in our Weekly Outlook early Monday, but don’t be surprised if much of the region sees its first frost of the fall Tuesday night.

Thursday night: Becoming partly cloudy. Low 61-68.

Friday: Morning sun, then clouds increase and thicken up in the afternoon with some showers likely, breezy. High 77-84, cooler near the South Coast and Cape Cod.

Friday night: Any showers end in the evening, skies clear out after midnight. Low 51-58.

Saturday: Plenty of sunshine with a few afternoon clouds. High 62-69.

Saturday night: Clear skies. Low 42-49, a little milder in urban areas and near the coast.

Sunday: Sunny in the morning, clouds return in the afternoon, chance for a few showers near the South Coast late in the day. High 59-66.

Sunday night: Mostly cloudy, chance for a few showers, mainly near the South Coast. Low 46-53.

Monday: Becoming partly to mostly sunny and breezy. High 62-69.

The rain will end and the sun will return, but not that quickly.

Much of southeastern Massachusetts has received 4-8″ of rain already. Image provided by CoCoRaHS.

Low pressure continues to sit off the East Coast, but it will slowly start to weaken and pull away from the area today. Winds have already diminished, but the coastal flood threat remains for at least one more high tide cycle. Occasional showers continue today, with a few embedded downpours, but the rain should gradually taper off and end across the region tonight or early Tuesday. The storm pulls away during the day on Tuesday, but the clouds will be slow to follow, with only some sunny breaks developing in the afternoon. High pressure then builds in with drier and warmer weather for Wednesday into Friday. A couple of weak disturbances may bring in some clouds at times, but we’ll remain dry until a cold front triggers a few showers on Friday. Saturday should be drier and cooler as high pressure builds back in to the north, but Sunday is a question mark at this point. We’ll have another large high to the north and low pressure moving from the Tennessee Valley toward the Mid-Atlantic coastline. Does moisture from that low get in here on Sunday or does the high keep it to our south. It’s too early to answer that, but at this point, we’re fairly confident that the next storm will not be anywhere near as potent as the one we’re dealing with now.

Sunday could be wet, or it could be dry. Too early to tell which. Images provided by Pivotal Weather.

Monday: Breezy with periods of rain and showers, some downpours possible. High 56-63, a little milder across southeastern Massachusetts and Cape Cod.

Monday night: Showers gradually taper off from southwest to northeast, areas of fog likely. Low 49-56.

Tuesday: A few lingering showers early across parts of southern New Hampshire and the North Shore, otherwise lots of clouds with some afternoon sunny breaks. High 62-69.

Tuesday night: Partly to mostly cloudy. Low 50-57.

Wednesday: Partly sunny. High 65-72, coolest across Cape Cod.

Wednesday night: Partly cloudy. Low 53-60.

Thursday: A mix of sun and clouds. High 72-79, a little cooler across Cape Cod.

Thursday night: Partly cloudy. Low 59-66.

Friday: Partly sunny, slight chance for a shower. High 74-81.

Saturday: A mix of sun and clouds. High 62-69.

Sunday: Partly to mostly cloudy with a chance for showers. High 58-65.

As you have probably seen online or on television, there’s a storm on the way, and it could be a potent one.

A long duration coastal storm will impact the region this weekend. Loop provided by Tropical Tidbits.

It’s a little early in the season for a Nor’easter, but one is on the way, and it will have some impacts, especially near the coastline. A large high pressure area currently over Quebec will slowly drift eastward for the next few days while low pressure begins organizing off the Mid-Atlantic coastline. We are looking at a very long duration storm, starting on Friday, with effects lingering into Monday. As the system lifts northward it will slow down, and drift westward south of Long Island, before eventually moving off toward the northeast, possibly right across Southern New England. We’re caught in between the high to the north and low to the south for now, resulting in gusty winds, which will only get stronger, especially near the coast, as the system intensifies. Sustained winds of 25-40 mph are likely, with gusts to 50-60 mph possible (maybe even stronger), mainly near the coast. A Wind Advisory is in effect for inland locations and a High Wind Warning along the coast from 8am Friday until 2am Sunday. With all the leaves still on the trees, this will increase the risk for downed limbs and power outages.

Wind gusts of 40-50 mph are possible across the region. Image provided by WeatherBell.

The persistent east to northeast winds are also creating rough seas, with increasingly large waves crashing into the coastline. With astronomical high tides this weekend, some areas of coastal flooding are likely, especially east and northeast facing coastlines. Coastal Flood Watches and High Surf Advisories have been issued for the eastern coast of Massachusetts, including Cape Cod and the Islands, from Friday afternoon into Sunday evening.

Coastal flooding may be an issue for eastern Massachusetts. Image provided by the National Weather Service office in Norton, MA.

Aside from the wind and coastal threat, we’re also looking at some significant rainfall from this system. Some showers may develop during the day on Friday, but the high to the north should provide enough dry air to prevent much rain during the daytime hours. Steadier rain likely moves in at night from southeast to northwest, with rain continuing for most of Saturday, possibly heavy at times. Rain may taper off a bit on Sunday, but we’re still looking at occasional light rain, sometimes heavier for much of the day. Showers continue for Sunday night and a good chunk of Monday before the system finally starts to pull away. Widespread rainfall totals of 1-3 inches are likely, lesser amounts the farther west you go. Across eastern Massachusetts, even heavier totals are likely, with some models showing the potential for rainfall totals exceeding 5 inches. Because it is going to fall over the span of 48-72 hours, and it has been relatively dry again recently, widespread flooding is not expected, but areas of localized flooding are certainly expected.

Some hefty rainfall totals are possible across eastern Massachusetts. Image provided by Pivotal Weather.

Thursday night: Becoming mostly cloudy, breezy, especially near the coast. Low 46-53

Friday: Cloudy and breezy, showers possible in the afternoon, mainly across the South Coast and Cape Cod. High 61-68.

Friday night: Rain overspreading the region from southeast to northwest, windy, especially near the coast. Low 51-58.

Saturday: Wind-swept rain, possibly heavy at times. High 57-64.

Saturday night: Windy with more rain, possibly heavy. Low 50-57.

Sunday: Periods of rain and showers, still windy, especially along the coast. High 56-63.

Sunday night: Breezy with more showers and some periods of steady rain at times. Low 50-57.

Monday: More showers, gradually ending, winds diminish. High 56-63.

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.

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.
