Some cooler weather is on the way for a good portion of the upcoming week. Hurricane Erin remains a potent storm east of the Bahamas, and could have a minor impact on the region later this week.

We’re starting the week off with high pressure building in, bringing us dry and rather cool conditions for Monday and Tuesday. Temperatures will only get into the 70s during the day, possibly staying in the 60s in a few spots, especially near the coast. Some of the normally cooler locations could drop into the 40s during the next few nights, especially tonight. Time to turn off the air conditioning and open the windows, but possibly grab an extra blanket at night. As we get to Wednesday, a weak disturbance will head out way from the Great Lakes, bringing in some clouds and a few showers as well. For now, the showers don’t look to be that heavy or widespread, but at this point, we need any rain we can get.

High pressure returns for Thursday with drier weather, and temperatures remaining on the cool side, but that might not be the whole story, as we’ll also need to keep an eye on Hurricane Erin. Erin should be passing well offshore (more on that a little later), but with a high to the northwest and the potent storm offshore, the gradient in between the two could result in some gusty winds across Cape Cod and the Islands, and possibly southeastern Massachusetts as well. In addition, the high clouds around the edge of Erin may dim the sun during the day. One thing that is definite is that Erin will produce rough seas, high waves, and a significant risk for rip currents at beaches across the region, especially across the South Coast and east-facing beaches on Cape Cod. When you add in the fact that there’s a new moon this weekend tides will be running astronomically high, so there is the chance for some coastal flooding in a few spots toward the end of the week.

Wave heights could reach 10 feet or more near the South Coast by Friday. Image provided by WeatherBell.

Once Erin pulls away Friday should be another sunny and cool day, but as the high pressure area moves offshore, it will allow warm and increasingly humid conditions to return on Saturday. Another frontal system may move in on Sunday with some showers and thunderstorms, but the timing is still in question, so don’t go cancelling any outdoor plans just yet.

Will Sunday be wet or will the showers hold off until late? It’s too early to tell. Images provided by Pivotal Weather.

As for Hurricane Erin, it peaked as a Category 5 hurricane north of Puerto Rico on Saturday then weakened a bit, before restrengthening Sunday night. As of 2am Monday, Erin was centered about 110 miles northeast of Grand Turk Island, moving toward the northwest at 12 mph. Maximum sustained winds were near 130 mph. Erin will turn more toward the north over the next day or so, and could strengthen a little more before a weakening trend begins. Erin should pass in between the East Coast and Bermuda towards midweek before turning more toward the northeast and heading out into the open Atlantic. As Erin heads northward it will expand in size, and some of its outer bands could clip Bermuda and/or the Outer Banks of North Carolina with some squalls around midweek. Erin will generate high waves, rough surf, and a high danger for rip currents up and down the East Coast this week.

Meanwhile, there’s another tropical wave we’ll be keeping an eye on in the Atlantic. The wave is pulling away from the Cabo Verde Islands today, and will make its way across the Atlantic this week. While conditions are not favorable for any development right now, toward the end of the week they could become a little more conducive, and some of the models show the potential for this system to develop towards next weekend as it heads toward the Lesser Antilles.

Another system crossing the Atlantic could develop later this week. Image provided by the National Hurricane Center.

Monday: Morning clouds, then becoming partly to mostly sunny, breezy early. High 69-76, coolest along the coast.

Monday night: Clear to partly cloudy. Low 47-54, a little warmer in urban areas and right along the coast.

Tuesday night: Partly cloudy. Low 54-61.

Wednesday: Partly sunny, chance for a few showers. High 71-78.

Weekend/Tropical Outlook: August 15-18, 2025

A good portion of the upcoming weekend should feature some very nice mid-summer weather. Meanwhile, Tropical Storm Erin continues to gather strength in the central Atlantic.

Temperatures will average close to normal through the weekend despite some ups and downs. Image provided by Weathermodels.com

A cold front will slide offshore this evening, taking any remaining shower and thunderstorm activity with it. Behind it, high pressure builds in with sunshine, cooler temperatures and lower humidity for Friday. As the high moves off to the east, temperatures will start to creep back up on Saturday, but will be pretty close to where they should be in mid-August. Sunday looks to be another hot and humid day, though it won’t be anywhere near as oppressive as some days we had earlier in the summer. A cold front will be approaching the region though, and it may produce some showers and thunderstorms late in the day and into the evening. High pressure then builds back in with much cooler and drier air for Monday.

Tropical Storm Erin continues to slowly intensify in the central Atlantic. Loop provided by NOAA.

Out in the central Atlantic Ocean, Tropical Storm Erin continues to slowly get its act together. As of 11am Thursday, Erin was centered about 890 miles east of the Northern Leeward Islands, moving toward the west at 17 mph. Maximum sustained winds were near 60 mph. Conditions are becoming more favorable for Erin to intensify, as wind shear is limited at this time, the atmosphere ahead of Erin is more moist, and sea surface temperatures gradually increase as you head westward. Erin is expected to become a hurricane on Friday. As for the track, that’s fairly simple for now. A large ridge of high pressure remains in place to the north, so Erin should continue in a general west to west-northwest direction for the next few days, likely passing north of the Caribbean this weekend. It may be close enough that some of the outer bands from the storm will bring squally conditions to parts of the Virgin Islands and Puerto Rico, but a direct hit is unlikely at this time. Erin should continue to intensify this weekend, likely become a major hurricane.

Beyond this weekend, things become a little less clear. Erin will encounter a weakness in the ridge to the north, which should allow the storm to turn more toward the northwest and then north. However, when that turn occurs and how quickly it will make the turn are still very uncertain. Most of the models show the storm passing in between Bermuda and the East Coast, eventually turning northeastern and heading out into the Atlantic, but that is far from a lock at this point. The earlier the turn happens, the bigger the threat to Bermuda. The later the turn happens, the more likely that the storm could impact parts of the Bahamas. The storm will produce rough surf and increase the chances for riptides along the East Coast next week, but for now at least, that looks to be the only impact from the storm. That could change if the turn happens later, but we’ll worry about that if it happens.

There’s also a system we’re keeping an eye on in the Bay of Campeche. A cluster of thunderstorms has been slowing organizing over the past day or so, and as it heads northwestward, conditions are favorable for some development over the next day or so. The system doesn’t have a lot of time, as it will likely move inland somewhere close to the Texas/Mexico border late Friday or Friday night, but it could become a Tropical Depression or Tropical Storm before moving inland. Whether it develops of not, heavy rain, gusty winds, and coastal flooding are possible in this region for the next few days.

We’re also keeping an eye on a developing system in the western Gulf of Mexico. Loop provided by NOAA.

Thursday night: Any lingering showers or thunderstorms end in the evening, becoming clear to partly cloudy overnight. Low 62-69.

Friday: Partly to mostly sunny, not as humid. High 76-83, coolest along the coast.

Friday night: Partly cloudy, some patchy fog may develop. Low 57-64.

Saturday: Sunshine and a few clouds. High 81-88, cooler near the coast.

Saturday night: Clear to partly cloudy. Low 62-69.

Sunday: Morning sun, then increasing clouds, chance for a late-day shower or thunderstorm, humid. High 85-92, a little cooler across the South Coast and Cape Cod.

Sunday night: Any showers or thunderstorms end in the evening, becoming partly cloudy overnight. Low 59-66.

Monday: A mix of sun and clouds, cooler and less humid. High 72-79.

Weekly/Tropical Outlook: August 11-17, 2025

Once again, most of this week will be fair quiet weather-wise. The tropics, however, are not going to be quiet.

Drought conditions are beginning to re-emerge, especially in SE Massachusetts and Cape Cod. Image produce by the National Drought Mitigation Center.

High pressure remains in control for the first half of the week with warm and increasingly humid conditions. While the humidity levels will be on the rise, it won’t be oppressive, certainly not like it was earlier in the summer. Temperatures will likely be near or over 90 degrees for the next few days inland, but a seabreeze will keep coastal areas cooler each afternoon. We could see a shower or thunderstorm across inland areas Wednesday, but otherwise, it should remain dry. A cold front will move in on Thursday, likely producing some showers and thunderstorms, along with some cooler weather. Temperatures on Thursday will be dependent on the timing of the front and the associated thunderstorms. A later arriving front likely means another day of 90-degress temperatures inland, but and earlier-arriving front would prevent that. High pressure builds back in with drier and cooler conditions on Friday. As the high slides off to the east, warmer weather will return for the weekend.

Tuesday looks like the hottest day with temperatures well into the 90s away from the coast. Image provided by Weathermodels.com

Now we’ll talk about the tropics. As you may have seen from all the Facebook Forecasters out there, Major Hurricane Erin is going to wipe out the East Coast in about 10 days. Well, that’s what a few of the models have shown at times over the past several days, and since the models show it, that’s what’s going to happen, because the models are always spot on 10 or more days in advance, right? Now, we’ll give you some real data. There is a strong tropical wave that moved off the west coast of Africa a few days ago. It has been fighting off some dry air and is over water that isn’t quite warm enough to sustain a tropical system, but it has shown some signs of organization in the past day or so. In fact, by the time some of you read this the National Hurricane Center may have already declared the system Tropical Depression 5. It will pass close to or over the Cabo Verde Islands today and then head in a general westward direction, likely strengthening as it does. The strengthening should be slow and steady as the system spending the next 5 day or so over the open waters of the Atlantic, and it will probably get upgraded to Tropical Storm Erin over the next day or two. It could become a hurricane later this week or next weekend. At that point, it should be approaching the longitude roughly near the Lesser Antilles. Most (but not all) of the models show the system passing north of the Islands, but that does not mean they are safe yet. However, around that point is an important spot to watch what the storm is doing. Some models show it turning more toward the northwest or even north at that point and heading out to sea (though possibly threatening Bermuda), while other models show it continuing off toward the west-northwest or even west. This would increase the threat to the Bahamas (and possibly the Greater Antilles). Of course, this is all still a week away, at which point the average error in the models is several hundred miles, so this really is just pure speculation. We won’t even get into how strong it might be, as intensity forecasts in the models are notoriously poor. For now, we’ll just say that it’s something to keep an eye on, but don’t worry about yet. *IF* it were to become a threat to the East Coast (and that’s a very big IF), we’ll give you plenty of advance notice. We’re not here for hype or page clicks (like the Facebook Forecasters), we’re here to give you a true look at what’s going on. We’ll likely be writing special blogs about this system (and the rest of the tropics) at various times this week. For now, ignore the noise, and listen to a trusted source, not one that picks out the scariest looking forecast model for 10 days from now and insists that is exactly what is going to happen (because it almost certainly won’t).

There’s still a wide range in model solutions for where the tropical system will track over the next 7 days. Image provided by Tomer Burg.

Remember how it rained nearly every weekend through the Spring? That won’t be the case this weekend.

It’s been quite dry across much of the area since June 1. Image provided by WeatherBell.

High pressure will dominate our weather right through the weekend. The high, currently centered over southeastern Canada will slowly drop southward, settling off the East Coast this weekend. Not only will we stay dry through this time, but temperatures will trend upward, and by the end of the weekend, so will humidity levels. The smoke and haze that has plagued us for the past few days from Canadian wildfires will thin out and drift away, so we’ll have sunshine for most of the time as well (during the daylight hours).

The forecast for most of the upcoming week will be a fairly simple one for our region. Meanwhile, Tropical Storm Dexter has developed in the Atlantic well off the East Coast, but it won’t have any impact here.

Little to no rainfall is expected across the region this week. Image provided by Weathermodels.com

High pressure will dominate our weather for most of the upcoming week, with mostly sunny skies, seasonably warm temperatures, and comfortable humidity levels. Today will likely be the warmest day, with some places across the interior approaching 90, but the rest of the week will feature temperatures mainly in the upper 70s and 80s across the interior, with seabreezes keeping coastal areas a little cooler. We could see a few pop-up showers and thunderstorms well inland towards midweek, but for the most part, it will remain dry into next week. Some smoke in hazy conditions at times, mainly during the first half of the week.

Smoke from Canadian wildfires will dim the sun at times through midweek. Loop provided by WeatherBell.

The only real question mark in the forecast is Sunday. As we mentioned in the previous blog about the tropics, we need to keep an eye on a potential system developing near the Southeast coast later this week. Some models bring the system into the Southeast or Carolinas, with some of the moisture drifting northward towards next weekend. Some models try to bring the system itself up the coast as the high shifts off to our east. Of course, this system may not even develop, and the entire point would be moot. Right now, it looks like the high may be strong enough to keep us dry, but also turning hot once again. We should have a much better idea when we get to our Weekend Outlook later this week.

We’ll be watching a potential low pressure area near the Southeast later this week to see if it may have any impact here down the road. Images provided by Pivotal Weather.

Tropical Storm Dexter developed late Sunday night off the East Coast. It was centered about 300 miles west-northwest of Bermuda, moving toward the east-northeast at 12 mph. Maximum sustained winds were near 45 mph. Dexter may strengthen a little more on Monday, but not much, as wind shear will remain in place. Beyond that, wind shear will take more of a toll on the system, and it will likely lose its tropical characteristics by midweek as it continues east-northeastward into the open waters of the Atlantic. It may churn up some rough seas and create some rip currents along the East Coast later this week, but that should be its only impacts.

The Tropics Are Waking Up

wxmanscottk1 Comment

Tropical activity usually begins to perk up in August, and right on cue, it is doing so, in both the Atlantic and the Pacific.

It’s been a slow start to hurricane season across the Northern Hemisphere. Image provided by Colorado State University.

After a slow start to hurricane season, conditions are starting to become more favorable for storms to develop, especially across the Atlantic. We’ve had three weak, short-lived storms thus far, which isn’t that unusual for June and July, but activity usually starts to ramp up in August. Saharan dust surges, which are common in June and July, should be starting to slow down over the next few weeks. Water temperatures continue to rise, and now are above the 26C (79F) threshold needed to sustain tropical systems across a large portion of the Atlantic, especially the Main Development Region (MDR). In addition, wind shear has been rather hostile across the tropics, but that is also starting to lessen. The tropical waves moving off the west coast of Africa have been a little more robust over the past few weeks, and although none of them have developed, it is only a matter of time until that changes. This is not the only place we need to watch for storms to develop however.

There are now three areas in the Atlantic being monitored for development. Image provided by the National Hurricane Center.

We’ll start off close to the East Coast where a frontal system is stalled out near the Carolinas. A wave of low pressure has developed along the front a few hundred miles off the North Carolina coastline. It is producing squally conditions in the offshore waters, and should head out to sea over the next few days. However, as it detaches from the front over the next day or so conditions will become favorable for development, and it could become a Tropical Depression or Tropical Storm over the next few days as it heads out to sea without impacting any land areas.

Low pressure is trying to develop off the East Coast. Loop provided by NOAA.

That might not be the only system we need to keep an eye on near the East Coast over the next week or so. Forecast models are showing the potential for another system to develop off the Southeast Coast later this week. Some models keep the storm weak and have it mill around near the Southeast for a few days, others are more bullish and develop the system and have it head up the East Coast, while other models have it stay offshore and head out to sea harmlessly. It’s too early to determine whether the storm will even form, never mind where it might go, but this is definitely something to keep an eye on as the week goes on.

Some models show the potential for another storm off the East Coast later in the week. Loop provided by Tropical Tidbits.

Elsewhere in the Atlantic, there are a couple of tropical waves crossing the Caribbean, but neither is expected to develop at this time. However, another wave will move off the west coast of Africa on Monday, and this one could bear watching. We already mentioned above how conditions across the Main Development Region are beginning to improve, and this wave could take advantage of those improving conditions. Many of the forecast models, especially the Ensembles, are showing significant potential for this wave to develop as it crosses the Atlantic. We’ve seen plenty of times before where the models are gung-ho with a system, and it doesn’t develop, so this is far from a lock. Even if it does develop, questions of where it goes and how strong it gets cannot be answered at this time, and probably won’t be for at least another week or so, and that’s if it even develops. Nevertheless, we’ll be keeping an eye on this wave in the coming days.

The Eastern Pacific could see more storms this week. Image provided by the National Hurricane Center.

In the Eastern Pacific, where activity has been closer to normal so far this season, more storms are expected this week. Former Hurricane Gil has become extratropical halfway between Mexico and Hawaii, and will no longer be a threat. However, an area of low pressure appears to be developing several hundred miles southwest of Mexico. Conditions are favorable for development, and this system could become a tropical depression by Monday. Forecast models show the potential for it to quickly develop, possibly becoming a hurricane by midweek. After that, it will start to move over cooler water, and should start to weaken fairly rapidly. Its remnants could bring gusty winds and rainfall to parts of Hawaii in a week or so, but that is far from certain.

An area of low pressure southwest of Mexico could become a tropical depression in the next 24 hours. Loop provided by Tropical Tidbits.

Meanwhile, forecast models show the potential for another system to develop south of Mexico later this week. While the models aren’t quite as bullish on this system as they are on the one mentioned above, they do show the potential for this system to become at least a tropical storm toward the end of the week. The difference with this one is that it will form quite a bit closer to Mexico, and could be a threat to parts of southern Mexico by the end of the week.

The Western Pacific is also getting more active. Image provided by the Joint Typhoon Warning Center.

In the Western Pacific there are also a couple of areas to watch. Tropical Storm Krosa is dissipating well northeast of Japan, and is not a threat as it heads out into open waters. Tropical Storm Bailu has maximum sustained winds near 40 mph, and was centered about 400 miles east-northeast of Tokyo Sunday evening. Bailu should maintain its current intensity for the next day or two, but will head east-northeastward, away from Japan and out to sea, without impacting any land areas. There is also an area of disturbed weather about 500 miles north of Wake Island that is being watched. Conditions are favorable for development, and this could become another tropical depression in the next day or so. Like the other active systems in the Western Pacific, even if this one develops, it will likely stay over open water without threatening any land areas.

As we flip the calendar we’ve some absolutely fantastic weather on tap for much of the upcoming weekend.

It’s going to be a rather wet night across the region. Loop provided by WeatherBell.

We’re starting off with some rain as a wave of low pressure rides along a stalled out frontal system just south of New England. Some of the rain could be heavy this evening and tonight, but the bulk of the heavy rain will stay southwest of our area, mainly across the Mid-Atlantic states. We do need the rain that we are getting though, as it has been on the dry side for the past couple of months, with drought conditions starting to re-emerge in spots. Once the rain ends Friday morning we’ll see skies start to clear out by late in the day, then high pressure builds in for the weekend with lots of sunshine. Temperatures will be a little below normal for Saturday but still rather mild, with a warming trend back to near normal on Sunday and a little above normal on Monday, but humidity levels will remain comfortable the entire time.

High temperatures should be in the lower to middle 80s in early August. Image provided by Weathermodels.com.

Thursday night: Periods of rain and showers, possibly heavy at times, tapering off late at night, breezy. Low 56-63.

Friday: Any lingering showers end in the morning, skies start to clear out in the afternoon, breezy. High 68-75.

Friday night: Becoming clear. Low 53-60.

Saturday: Sunshine and a few clouds. High 73-80.

Saturday night: Clear skies. Low 54-61.

Sunday: Plenty of sunshine. High 79-86, a little cooler across Cape Cod.

Sunday night: Clear skies. Low 58-65.

Monday: Mostly sunny. High 82-89, a little cooler near the South Coast and Cape Cod.

Heat and humidity return for the first half of the week, but the latter half will tell a different story.

Heat Advisories are in effect for the first half of the week. Image provided by the National Weather Service office in Norton, MA.

We start the week off with high pressure moving offshore, resulting in hot and humid conditions into Wednesday. Tuesday looks the be the hottest day of this stretch, with temperatures well into the 90s, and only a stray shower or thunderstorm providing minimal relief. Wednesday could also be quite hot, but we’ll have a cold front moving in, with clouds and a few showers and thunderstorms ahead of it during the afternoon. The front moves through and then stalls out near or just off the South Coast, which is where things get tricky.

It will feel like it is near or over 100 degrees Tuesday afternoon. Image provided by WeatherBell.

A wave of low pressure will ride along that front, bringing some rain and cooler air into the region. What’s uncertain is where the front stalls out, and the timing of the wave. For now, it looks like the bulk of the rain will be South of the Mass Pike, but that is highly uncertain. The rain could get all the way into southern New Hampshire, or it could be confined to the South Coast. This will be dependent om where the front actually is. How much rain will be dependent on how strong the wave is. Some models have light to moderate rain in spots, some show the potential for some hefty amounts. The other question is the timing. Some models show most of the rain Thursday and Thursday night, some have the heavier rain Thursday night into Friday, some even have it linger into Friday night. What you’ll see below is our best estimate on all these variables at this time, but it is obviously very low confidence. Behind the system high pressure builds in with cooler and drier weather for the weekend.

There’s a lot of uncertainty with the rainfall potential for the end of the week. Images provided by Pivotal Weather.

Monday: Patchy morning fog, otherwise mostly sunny, hot, and humid. High 85-92, cooler along the coast.

Monday night: Clear skies, a little patchy fog again. Low 65-72.

Tuesday: Sunshine and a few clouds, slight chance for an afternoon shower or thunderstorm. High 90-97, cooler across Cape Cod.

Tuesday night: Clear to partly cloudy. Low 66-73.

Wednesday: A mix of sun and clouds, chance for some late-day showers and thunderstorms. High 88-95, cooler across Cape Cod.

Wednesday night: Partly to mostly cloudy, showers and thunderstorms possible. Low 65-72.

Thursday: More clouds than sun with showers and thunderstorms likely. High 75-82.

Thursday night: Partly to mostly cloudy with more showers and thunderstorms. Low 58-65.

Friday: Showers and thunderstorms ending, becoming partly sunny. High 70-77.

Saturday: Lots of sunshine. High 73-80.

Lots of changes coming up this weekend, but the humidity will probably hang around.

It will feel like it is near or over 100 degrees Friday afternoon. Image provided by WeatherBell.

High pressure settles offshore, keeping us on the warm and humid side. In fact, Friday will be downright hot with many places away from the South Coast getting into the 90s. When you factor the humidity it, it may feel like it is close to or a little over 100 in the afternoon. However, we’ll also see clouds moving in ahead of a cold front. That front will trigger some showers and thunderstorms during the afternoon and evening. We’re not expecting widespread severe weather, but some of the storms could produce gusty winds and heavy downpours. The front settles offshore before stalling out, with somewhat cooler and drier air moving in for Saturday. By somewhat, we mean temperatures in the 80s instead of 90s, and dewpoints in the upper 50s and lower 60s instead of upper 60s and lower 70s. So, it’ll be a typical summer day across the region. Sunday may not be as nice. A wave of low pressure will ride along the front and bring the humidity back in, along with the possibility some showers and thunderstorms, mostly during the afternoon and evening. However, some models keep the showers offshore, so we may end up with a decent day. High pressure returns for Monday with sunshine, warmer temperatures, and moderate humidity levels.

Will Sunday be wet or dry? It depends on which model you trust. Images provided by Pivotal Weather.

Thursday night: Clear skies. Low 66-73.

Friday: Some morning sun, then clouds move in with some showers and thunderstorms likely during the afternoon. High 88-95, cooler across the South Coast and Cape Cod.

Friday night: Showers and thunderstorms ending in the evening, becoming clear to partly cloudy after midnight. Low 63-70.

Saturday: A mix of sun and clouds. High 80-87, a little cooler near the coast.

Saturday night: Becoming partly to mostly cloudy. Low 60-67.

Sunday: More clouds than sunshine, showers and thunderstorms may develop in the afternoon. High 75-82.

Sunday night: Cloudy with any showers and thunderstorms ending during the evening, becoming partly cloudy late at night. Low 62-69.

Monday: Becoming mostly sunny. High 84-91, cooler across the South Coast and Cape Cod.

Quiet weather will dominate much of the upcoming work week.

It could get rather chilly tonight in some areas. Image provided by weathermodels.com

High pressure builds in for Monday and Tuesday with sunshine, low humidity and temperatures that are a little below normal for late July. Highs will only be in the 70s and lower 80s both days. With clear skies and diminishing winds tonight we could have ideal conditions for radiational cooling, resulting in low temperatures dropping into the 50s, with some 40s in the normally colder locations. As the high slides offshore on Wednesday temperatures will start to moderate, but the heat and humidity will really make a comeback for Thursday, and especially on Friday. Temperatures will get well into the 90s on Friday, but when the humidity is factored in it will feel like it is over 100 degrees in the afternoon. An approaching cold front may trigger some showers and thunderstorms Friday afternoon, but it looks like the front will stall out nearby and remain there for the weekend. That means it will remain humid with a daily chance for showers and thunderstorms. Temperatures will likely stay quite warm, but how hot it gets each day will depend on the amount of sunshine we see.

The heat index will be near or over 100 Friday afternoon. Image provided by WeatherBell,
