There’s a four letter word that begins with the letter R and rhymes with main that we really need, but you won’t find it in our forecast for the next week.

None of the models are forecasting any rain around here for the next 7 days. Images provided by Pivotal Weather.

The week starts off with high pressure in control, keeping us rather mild for the end of the September. A cold front will move through on Tuesday, but only a few clouds will accompany it. Behind it, strong high pressure builds in with gusty north to northeast winds bringing much cooler air in for Wednesday and Thursday. Meanwhile, with Hurricane Humberto and Tropical Storm Imelda well offshore (more on them in a moment), the gradient between the large high and those systems will result in gusty winds towards the middle of the week. By the end of the week and the weekend, the high will slide off to the south, keeping us dry, but with temperatures getting back to near to above normal levels.

Meanwhile, as previously mentioned, we have both Hurricane Humberto and Tropical Storm Imelda in the Atlantic at this time. While both storms could bring some adverse weather to Bermuda over the next few days, and they will both generate rough surf for the East Coast, they should both stay offshore, much to dismay of the Facebook Forecasters everywhere who were tossing around phrases like “Fujiwara Effect” without actually understanding what it meant.

Tropical Storm Imelda (lower left) and Hurricane Humberto (lower right) continue to churn up the Atlantic. Loop provided by NOAA.

As of 2am Monday, Hurricane Humberto was centered about 400 miles south-southwest of Bermuda, moving toward the northwest at 14 mph. After reaching Category 5 strength over the weekend, the storm was still a Category 4 system with maximum sustained winds near 140 mph. Humberto should turn northward passing west of Bermuda Monday night and Tuesday before turning northeastward. Humberto may produce some gusty winds and heavy rain across Bermuda, which is why a Tropical Storm Watch has been issued. By Wednesday, Humberto will transition into an extratropical storm as it heads east-northeastward into the open waters of the Atlantic.

Closer to the East Coast is Tropical Storm Imelda, crossing the Bahamas early this morning while moving northward at 8 mph. Imelda has maximum sustained winds near 45 mph, and has been very slow to get organized. It will continue to bring squally conditions to the northwestern and central Bahamas on Monday where a Tropical Storm Warning remains in effect. As Imelda heads northward, some heavy rain may impact coastal portions of the Carolinas. By Tuesday, the storm should make a hard right turn and pull away from the coast, while strengthening, possibly becoming a hurricane by midweek. The current forecast calls for Imelda to pass very close to Bermuda Wednesday night or Thursday as a hurricane, making for a very rough week for the British Overseas Territory. After that, it should also become an extratropical storm over the open waters of the Central Atlantic.

We’re not going to get much, if any, relief for the drought this week across the majority of the region, but temperatures should remain comfortable.

Over the past 90 days, rainfall totals across the region are roughly 2-5 inches below average normal. Image provided by WeatherBell.

We start the week off with high pressure in control, giving us a couple of dry and warm days for Monday and Tuesday, with a seabreeze keeping coastal areas a little cooler, especially today. Wednesday and Thursday are the days with the most uncertainty at this point. We’ll still have high pressure to the north, but a low pressure area will be passing offshore. This will send in some clouds, but similar to last week’s system the question is how far north the rain shield will get. Some models keep it all offshore, several bring it up to the South Coast, some bring in farther inland. Given then the models overestimated how far inland it would get with the system last week, we’re inclined to think that the rain probably won’t get much farther inland than the South Coast, with most of it falling Wednesday night into early Thursday. The system pulls away later Thursday, then a cold front drops down from the north on Friday. The models show most of the rain with the front drying up before it gets here, so the front should move through with little fanfare on Friday. Behind it, high pressure returns with much cooler air on Saturday, though temperatures should start to moderate a bit on Sunday.

Most of the models keep what little rain we’re expecting close to the South Coast late Wednesday into Thursday. Images provided by Pivotal Weather.

Monday: Areas of morning fog, otherwise partly to mostly sunny. High 71-78, a little cooler along the coast.

Monday night: Partly cloudy, areas of fog developing. Low 50-57.

Tuesday: A mix of sun and clouds. High 70-77, a little cooler along the coast.

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

Wednesday: More clouds than sun, chance for a few showers, mainly near the South Coast. High 69-76.

Wednesday night: Partly to mostly cloudy, chance for a few showers near the South Coast. Low 54-61.

Thursday: Morning clouds, maybe a shower near the South Coast, becoming mostly sunny during the afternoon. High 75-82, a little cooler across Cape Cod.

Thursday night: Mostly clear. Low 55-62.

Friday: Partly to mostly sunny. High 76-83.

Saturday: Plenty of sunshine, cooler. High 63-70.

Sunday: Mostly sunny. High 65-72.

Much of the upcoming week will be dominated by quiet and cool weather thanks to a large high pressure area.

Temperatures will be several degrees below normal for much of the week. Image provided by WeatherBell.

The cold front that produced severe weather on Saturday and a cool but beneficial rainfall on Sunday has pushed offshore and high pressure will build in bringing drier air in along with temperatures that are below normal for today and Tuesday. Things could get a little complicated for part of the region for Wednesday. An area of low pressure will pass well offshore, but the precipitation shield around the edge of the system could get close to parts of the South Coast, possibly even a little farther northward. However, the high to the north looks like it may remain strong enough to keep most of the rain offshore, so we’re going to lean towards a dry forecast for now. High pressure returns for the end of the week and start of the weekend. A cold front will move through with little fanfare on Sunday, keeping us dry.

An offshore system may produce some rain across Cape Cod and the South Coast, or maybe it won’t. Images provided by Pivotal Weather.

Happy Labor Day and welcome to September. It marks the unofficial end of summer and the official start of meteorological autumn. College football is underway, the pros start this week, hockey training camps start up in a couple of weeks, pumpkin everything is available everywhere, and after a cool August, warmer weather will return for a few days this week.

Temperatures were below normal across much of the Northeast during August. Image provided by the Northeast Regional Climate Center.

High pressure will keep us dry for the first half of the week, likely right into Thursday, but with an upper-level low nearby, we’ll still have some afternoon clouds each afternoon. Temperatures will be close to normal for early September to start the week, but as the high slides offshore, southwest winds will bring warmer and eventually more humid air in towards Wednesday and Thursday. A slow-moving cold front will move in Thursday night, with some showers and a few thunderstorms likely on Friday. With the front taking its time, Saturday may also be a warm and humid day, with the potential for some additional showers or thunderstorms, depending on when the front actually moves across the region. High pressure should build in behind the front for Sunday with cooler and drier weather, just in time for the Patriots home opener in Foxborough.

We’re not expecting a lot of rain with the cold front at the end of the week, but every little bit helps as the drought worsens. Images provided by Pivotal Weather.

The final week of summer (traditional and meteorological) has arrived, and for the most part, the weather will be fairly nice, but a little on the cool side.

Below normal temperatures are expected for most of the upcoming week. Image provided by WeatherBell.

We start the week off with some rain across the Cape and Islands as a weak low pressure area passes by offshore. The rain should end during the morning, but we’ve got a cold front moving in from the west. We could see some sunshine, especially inland during the morning, but as the front moves in, we’ll see some showers and thunderstorms developing in the afternoon. They shouldn’t be that strong, but a few could produce some gusty winds and heavy downpours. They’ll quickly subside during the evening as the front pushes offshore, then high pressure starts to build in with cooler and drier conditions. However, we’ll also have an upper-level low pressure area moving in from the Great Lakes, and this will likely generate some clouds for Tuesday afternoon. It’ll probably be a little too dry for any showers to pop up, but it wouldn’t be a complete shock if a few days. Another disturbance rotating around that upper low will move in for Wednesday, with some morning sun followed by afternoon clouds, and this day may feature a better chance for some pop-up showers during the afternoon. Thursday looks like another dry day with some afternoon clouds and temperatures that remain a little below normal for late August.

A series of upper-level disturbances will influence our weather for much of the next week. Loop provided by Tropical Tidbits.

As we get to Labor Day weekend, we’ll see another low pressure area moving in on Friday, with another round of showers and possibly some thunderstorms. The system will take its time moving out as another upper-level low moves in, so Saturday may feature more clouds and a few showers, especially early, but we should see some improvement during the afternoon. Sunday looks pretty nice, but we’ll still have an upper-level low nearby, so expect more clouds, but for now, we’re not expecting more showers. High pressure builds in for Labor Day with dry and seasonably warm conditions, though some clouds are still likely as that upper-level low will be slow to depart.

Friday could feature some showers and thunderstorms, but much of the rest of the weekend looks dry. Images provided by Pivotal Weather.

Monday: Morning showers across Cape Cod, otherwise morning fog burns off revealing a mix of sun and clouds with some showers and thunderstorms likely during the afternoon. High 75-82.

Monday night: Any showers end in the evening, becoming clear overnight with some patchy fog. Low 56-63.

Tuesday: Morning sun, then some clouds pop up during the afternoon. High 72-79.

Tuesday night: Clear to partly cloudy. Low 52-59.

Wednesday: Partly sunny, chance for a few showers during the afternoon. High 70-77.

Wednesday night: Mostly clear. Low 51-58.

Thursday: Morning sunshine with afternoon clouds. High 73-80.

Thursday night: Partly cloudy. Low 53-60.

Friday: Partly sunny with showers and a few thunderstorms developing in the afternoon, tapering off late at night. High 71-78.

Saturday: Any lingering showers end early, some afternoon sunshine develops. High 68-75.

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

Labor Day: Partly sunny. High 71-78.

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.

Temperatures will be below normal for much of the upcoming week. Image provided by Weathermodels.com

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.

Drought conditions are expanding and worsening across the Northeast. Image provided by the National Drought Mitigation Center.

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

Tuesday night: Partly cloudy. Low 54-61.

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

Wednesday night: Partly cloudy. Low 54-61.

Thursday: Sunshine filtered through some high clouds, especially across southeastern Massachusetts and Cape Cod, where it will also be breezy. High 71-78.

Thursday night: Clear to partly cloudy. Low 53-60.

Friday: Some high clouds early, otherwise sunny, breezy across southeastern Massachusetts and Cape Cod. High 77-84.

Saturday: Sunshine and some afternoon clouds, breezy. High 80-87, a little cooler at the coast.

Sunday: Partly sunny, breezy, a little more humid, chance for some showers and thunderstorm. High 77-84.

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.

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.

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.

Sunday: More sunshine. High 78-85.

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,
