Arctic Air and Snow Heading for New England

The biggest snowstorm this area has seen in a few years is on the way, with arctic air preceding it.

An arctic cold front will cross the region later today, producing a few snow showers or squalls, but gusty northwest winds behind the system will usher in the coldest air so far this winter for the weekend. Temperatures will plunge into the single numbers tonight with some subzero readings possible. When you factor in the wind, it will feel like it is 10 to 20 below zero if you are outside Saturday morning. Despite some sunshine, temperatures will struggle to reach the teens on Saturday, but the wind will subside. We’ll see high clouds start to stream in during the afternoon as a developing low pressure system heads our way.

Bundle up if you need to head outside for any reason Saturday morning. Image provided by WeatherBell.

That system will move into the Deep South, and a secondary area of low pressure will develop near the Carolinas or Virginia Tidewater region. as it starts to strengthen it will move northeastward, passing south and east of New England Sunday night and Monday. There is still a little question as to how far north the low gets, which has some implications on the forecast, as it could result in some sleet near the South Coast, but for the bulk of the region, we’re looking at snow, thanks to the cold air already in place.

Because it will be so cold for much of the region, it will be a fluffier snow, which can pile up more quickly. The colder the air is, the less moisture it can hold. In general, 1 inch of liquid will result in 10 inches of snow when the temperature is near freezing. When temperatures are in the teens, as they will be across the interior for this storm, that ratio can change to as much as 15-20 inches of snow for 1 inch of liquid.

Closer to the coast, especially south of Boston, temperatures will not be nearly as cold, thanks to something meteorologists refer to as a “coastal front”. Ocean temperatures remain near or a little over 40, so as winds blow over that water and reach the coast, we will see temperatures moderate into the 20s, or even lower 30s, but that air usually doesn’t penetrate too far inland. So, you end up with a sharp boundary, or front, where temperatures go from the teens to the west and 20s to the east over a span of just a few miles. Exactly where that front sets up makes a big difference, not only because it’s the difference between fluffy snow and wet snow, but also because that front provides a little bit of lift, which usually results in some of the heaviest snow totals just to the west of that coastal front. As the system starts to pull away on Monday, that coastal front will quickly move southeastward, allowing the very cold air to quickly return to southeastern Massachusetts.

The coastal front is easy to find on temperature maps for Sunday evening. Image provided by WeatherBell.

For the timing, it looks like the snow will move in near or just after midday on Sunday from southwest to northeast, reaching southern New Hampshire by mid-afternoon. The steadiest and heaviest snow is likely from about 6pm to 2am. If there is going to be any sleet near the South Coast, it will likely be between about 10pm and 3am. As the storm starts to pull away on Monday, we’ll still see occasional light snow for much of the day, with some additional accumulations possible. Everything should finally wind down and end Monday evening.

Many models show the potential for some sleet near the South Coast around midnight Sunday night. Images provided by Pivotal Weather.

Now, the part you’re all waiting for – how much snow can we expect? There’s still a few details to be worked out that will impact the final numbers (where does the coastal front set up? will there be sleet near the South Coast?), but for the most part, we feel confident enough to put the pen to the paper so to speak. For most of the region, we’re looking at a general 12-18 inches. There will be some spots that get a little more, and there could be a little less near the South Coast, especially if there’s some sleet involved.

The NWS Blend of Models is mostly closely aligned with our thinking. Image provided by Weathermodels.com

In case you’re curious, the last time some cities around here received a foot or more in a single storm:

Boston: January 29, 2022 – 23.6″
Blue Hill: January 29-30, 2022 – 27.6″
Lowell: January 6-7, 2024 – 15.8″
Worcester: January 6-7, 2024 – 15.5″
Providence: January 28-29, 2022 – 19.3″
Hartford: February 1-2, 2021 – 12.1″
Manchester: December 1-3, 2019 – 20.8″

Once this storm pulls away, cold air will remain in place for much of the upcoming week, so don’t expect any melting any time soon.

You may have heard that there’s a little storm on the way. Well, before that happens, it’s also going to get ridiculously cold. We’ll get to all of that in this blog, but we’ll tell you right now, you won’t find a forecast for snow amounts. It’s too early for that, and there’s too much uncertainty still. We’ll tell you how we think the storm will evolve and its likely impacts around here, how cold it will get Before the Storm (and how that will impact things), and lots of musical references, but we’re not going to give you a snowfall forecast. We may do that in another blog post tomorrow, but for now, we’ll leave the hype to all of the TV meteorologists and Facebook Forecasters of the world.

A variety of watches, warnings and advisories are in effect across the eastern US. Image provided by the National Weather Service Eastern Region

After a somewhat mild day today, a cold front will move through this evening, possibly accompanied by a few snow showers, but the more noticeable effect will be cooler air moving in tonight. On Friday, an arctic cold front will cross the region, possibly with some additional snow showers or squalls, and that is what will start the Change in the Weather. Bitterly cold air will flood into the region behind that front. Temperatures will plunge into the single numbers and below zero across the region, with wind chills well below zero thanks to gusty northwest winds, making you dream about those Hot Summer Nights. A Cold Weather Advisory is in effect for much of the region. On Saturday, sunshine will start to fade as high Clouds Race Across the Sky, but it will remain Stone Cold, with high temperatures only getting into the teens at best, with wind chills still near or below zero before winds die down in the afternoon. Clouds will continue to stream in Saturday night, but it will remain chilly. This brings us to Sunday.

Wind chills of -10 to -20 are expected Saturday morning. Image provided by WeatherBell.

Low pressure moving into the Southwest will run into the arctic airmass covering much of the eastern two-thirds of the nation over the next few days. Moderate to heavy snow is expected from the Southern Plains across to the Tennessee Valley and parts of the Southeast and Mid-Atlantic states. To the south of these areas, a significant sleet and freezing rain storm is likely from parts of Texas into the Deep South. Places like Dallas, Little Rock and perhaps Nashville and Atlanta could be Trapped Under Ice by the end of the weekend. By Sunday, that system will move off the Carolina coast and head northeastward, developing as it passes south and east of Cape Cod early Monday. Sunday will start off cloudy and cold, with snow likely moving in by mid-to-late afternoon from southwest to northeast. With some very cold air in place, it will be more of a fluffy snow, easier to clean up, but it also piles up a lot more quickly. Snow will continue through the night, possibly heavy at times, slowly winding down during the day on Monday. The questions now are:

  1. How much does the very dry air in place slow down the start of the snow on Sunday?
  2. How heavy does the snow fall at times Sunday night into Monday?
  3. When will the snow actually end?
  4. How close will the system actually track to the coast?
  5. Will temperatures get up close to freezing across parts of southeastern Massachusetts behind a coastal front?
  6. Could there be some sleet and/or rain near the South Coast and Cape Cod?

With this many questions that we don’t have answers to at this point, it would be irresponsible to try and forecast snowfall totals, so we won’t do that. We will say that it is likely that much of the region gets 6 inches or more, but beyond that, we won’t commit to anything else.

After some snow showers/squalls tonight and Friday, you see the snow spreading in on Sunday. Loop provided by Weathermodels.com

Thursday night: Partly to mostly cloudy, chance for a few snow showers, skies start to clear out late at night. Low 16-23.

Friday: A mix of sun and clouds, chance for some snow showers or squalls, breezy. High 27-34.

Friday night: Becoming clear, breezy, and bitterly cold. Low -3 to +4, a little milder across Cape Cod.

Saturday: Sunny and breezy in the morning, high clouds stream in during the afternoon. High 10-17.

Saturday night: Becoming mostly cloudy. Low -1 to +6.

Sunday: Cloudy with snow developing by mid-to-late afternoon. High 13-20 north and west of I-95, 21-28 south and east.

Sunday night: Snow likely, possibly mixed with a little sleet or rain near the South Coast and Cape Cod, becoming breezy. Low 8-15 north and west of I-95, 16-23 south and east.

Monday: Snow gradually ending, breezy. High 16-23 north and west of I-95, 24-31 south and east.

If you’re looking for a week for a tropical vacation, this may be the one, because we’re in for some very chilly air at times this week.

Wind chills will be in the single numbers and below zero when you head out the door Wednesday morning. Image provided by WeatherBell.

Snow will end this morning as low pressure pulls away from the region, with some clearing possible during the afternoon. However, an arctic cold front will move through this evening, possibly accompanied by a few snow showers or squalls. They shouldn’t be that widespread, but could cause a few issues if you have to get caught under one. Luckily they’ll be moving through during the night, when very few people will be on the roads. High pressure builds in on Tuesday, with a very cold day despite sunshine. Temperatures will only get unto the upper teens and 20s, with wind chills in the single numbers or below zero. As the high moves off to the east, temperatures will start to moderate, but we’ll also see some clouds start to move in during the day ahead of the next storm system. This storm will bring in some snow showers late Wednesday night and early Thursday, but it shouldn’t be that big of a deal. High pressure then builds in with some bitterly cold air for the end of the week and the weekend.

High temperatures will only be in the teens on Saturday, Image provided by Weathermodels.com

By the end of the weekend we’re going to be keeping an eye on a storm system passing south of the region. We’ll have plenty of cold air with a large area of high pressure in place, the question is, how far north does the precipitation get. Some models keep it well to the south, with the high to the north keeping us very cold but dry, others have the precipitation move in with some snow possible. At this point, it’s still nearly a week away, so it’s impossible to tell which, if either, solution will be right. For now, we’ll just keep an eye on it as the week goes on, but we’re leaning towards the bitterly cold and dry solution.

Most of the models keep us dry and bitterly cold next Sunday, but not all of them. Images provided by Pivotal Weather.

Monday: Snow showers ending in the morning, some afternoon sunny breaks develop, becoming breezy. High 29-36.

Monday night: Partly cloudy with a chance for a few snow showers before midnight, clearing after midnight, breezy. Low 12-19.

Tuesday: Partly to mostly sunny, breezy. High 19-26.

Tuesday night: Clear skies. Low 4-11.

Wednesday: Morning sun, then increasing afternoon clouds. High 25-32.

Wednesday night: Mostly cloudy, chance for snow showers after midnight. Low 21-28, temperatures may rise a little overnight.

Thursday: Partly to mostly cloudy, breezy, some snow showers possible in the morning. High 35-42.

Thursday night: Becoming clear. Low 14-21.

Friday: Partly sunny, breezy, colder. High 23-30.

Saturday: A mix of sun and clouds, breezy. High 14-21.

Sunday: Partly sunny. High 11-18.

We’re in an active weather pattern, but that doesn’t mean it’s a snowy one.

Wind chills will be near or below zero Friday morning. Image provided by WeatherBell.

The storm that brought us the snow on Tuesday will continue to pull away tonight, taking any lingering snow showers along the coast with it, then skies should clear out for a while this evening, before clouds quickly return. A weak disturbance may produce a few snow showers Christmas morning, then we’ll start to clear out in the afternoon as a cold front drops southward across the region. Breezy and colder weather settles in for Christmas night into Friday morning, then clouds come right back in. Low pressure moving out of the Great Lakes will head southeastward, passing south of the region Friday night and Saturday. The question is – how far north does the precipitation shield from the system extend? Some models bring the snow all the way up to the MA/NH border, some only bring it to the South Coast. We think it’ll be somewhere in between, so we’re expecting some light snow Friday night into Saturday morning mainly south of the Mass Pike. The farther south and west you go, the better the chance for some accumulations. Drier weather returns later Saturday with some clearing, but clouds quickly return again on Sunday as another system heads our way. This one will likely pass north and west of the region, with rain Sunday evening into Monday morning. However, there may be enough cold air in place late Sunday so that the precipitation starts as some sleet or freezing rain north and west of Boston, before changing to plain rain at night. A cold front trailing the system moves through Monday morning, with clearing, breezy, and colder weather returning in the afternoon.

Will it snow Friday night or not? The models don’t agree. Images provided by Pivotal Weather.

Christmas Eve: Becoming clear this evening, clouds return after midnight. Low 19-26, temperatures may rise after midnight.

Christmas Day: Morning clouds, chance for a few flurries or sprinkles, becoming partly sunny and breezy in the afternoon. High 36-43.

Thursday night: Clear skies, except partly to mostly cloudy across much of Cape Cod, breezy. Low 6-13.

Friday: Morning sun, then increasing clouds. High 20-27.

Friday night: Plenty of clouds, chance for some light snow, mainly south of the Mass Pike. Low 11-18.

Saturday: Morning clouds and possibly some light snow, then becoming partly sunny. High 24-31.

Saturday night: Partly cloudy. Low 12-19.

Sunday: Some morning sun, then clouds return. High 34-41.

Sunday night: Cloudy with rain developing, possibly starting as freezing rain or sleet north and west of Boston. Low 25-32 in the evening, temperatures rise overnight.

Monday: Rain ending, some late-day clearing, breezy. High 37-44.

Astronomical Winter begins at 10:03am Sunday, but until then, Mother Nature can’t decide which season we’ll get to experience.

Temperatures will get well into the 50s on Friday. Image provided by Weathermodels.com

A low pressure system that prompted blizzard warnings in the Dakotas today will quickly move into southeastern Canada by tomorrow. Don’t worry, we’re not expecting blizzard conditions around here, but some heavy rain and strong winds are a lot more likely. With the system passing to our north, we’ll be in the warm side, and southwest to southerly winds will increase ahead of a cold front trailing the system. As the clouds move in later today and tonight the increasing winds will allow temperatures to rise for much of the night, climbing well into the 50s. The rain moves in after midnight, and it could be briefly heavy Friday morning. South winds of 20-30 mph, gusting to 50 mph at times will bring in unseasonably warm air, with some places possibly reaching 60. The cold front comes marching through around midday, quickly bringing an end to the rain. As winds shift into the west they will diminish a little, but will also usher much cooler air in, with temperatures quickly dropping into the 40s and 30s by evening. There could be a few rain or snow showers as the colder air rushes in, but for the most part, once the front moves through we’ll dry out. The gusty winds will also help to dry out the roads, so black ice shouldn’t be a problem Friday night and early Saturday, but you should probably use some caution if you’re heading out.

Wind gusts of 40-50 mph are expected on Friday, a little stronger on Cape Cod. Image provided by WeatherBell.

We’ll clear out and turn colder for Friday night and Saturday, but clouds quickly stream back in Saturday afternoon and evening. Another weak system passes by to our north, but it doesn’t look like it’ll be accompanied by much, if any precipitation Saturday night and Sunday. It will bring in some milder weather once again, as temperatures get back into the 40s Sunday afternoon. Skies clear out behind that system later Sunday, with gusty west winds bringing cooler air back in for Sunday night and Monday as high pressure builds back in.

Temperatures Saturday morning will be 25-35 degrees colder than they were at the same time Friday morning. Image provided by WeatherBell.

Thursday night: Becoming mostly cloudy and breezy with rain developing after midnight. Low 33-40 during the evening, temperatures rise overnight.

Friday: Cloudy and windy with rain, possibly heavy in the morning, ending in the afternoon. High 52-59, temperatures start dropping quickly in the afternoon.

Friday night: Chance for a few rain or snow showers during the evening, gradual clearing overnight, breezy. Low 22-29.

Saturday: Sunny in the morning, clouds return in the afternoon. High 35-42.

Saturday night: Plenty of clouds, becoming breezy. Low 28-35 during the evening, temperatures hold steady or rise a little overnight.

Sunday: Becoming partly sunny and breezy. High 41-48.

Sunday night: Partly cloudy, breezy, colder. Low 18-25.

Monday: Mostly sunny, breezy in the morning. High 26-33.

The weather pattern this week will be active, but not that impactful.

Wind chills will be in the single numbers and teens today behind a strong cold front. Image provided by WeatherBell.

We start the week on a chilly note as an arctic cold front crossed the region early this morning. Skies will clear out behind it today, but breezy and chilly weather is expected. As winds die down this evening, skies will be mostly clear, setting up a very chilly night, with many places once again dipping into the single numbers Tuesday morning. The cold weather will be short-lived as low pressure sures toward southeastern Canada, sending a warm front our way. We’ll see clouds moving in during the day, with a few snow showers accompanying the warm front in the evening. Wednesday should be a milder day, with a few places making a run at 50 degrees. However, we’ll also have some precipitation, mostly in the form of rain showers, possibly starting as a little snow, especially well north and west of Boston. The cold front moves through late in the day, then we’ll see some clearing for Thursday with cooler weather returning, but with an upper-level low moving through we could see a few snow showers popping up. High pressure settles in for Friday with cool and dry conditions. Another quick moving system may bring in some snow showers Friday night and early Saturday, though some models keep the system off to our south, then high pressure returns with colder weather once again later Saturday into Sunday.

Some mild weather and rain are expected on Wednesday. Image provided by Weathermodels.com

Monday: Partly to mostly sunny, breezy in the morning. High 21-28, a little milder across Cape Cod.

Monday night: Clear to partly cloudy. Low 5-12 inland, 13-20 in urban areas and along the coast.

Tuesday: Morning sunshine, then clouds stream in during the afternoon. High 26-33, a little milder across the South Coast and Cape Cod.

Tuesday night: Mostly cloudy, chance for some snow showers during the evening north of the Mass Pike, rain or snow showers south. Low 19-26 during the evening, a little milder across the South Coast and Cape Cod, temperatures rise overnight.

Wednesday: Plenty of clouds with showers likely, any snow will be confined to areas north of Concord, NH. High 39-46, a little milder across southeastern Massachusetts, southern Rhode Island, and Cape Cod.

Wednesday night: Showers ending, partial clearing late at night. Low 29-36.

Thursday: A mix of sun and clouds, breezy, chance for a snow shower. High 35-42.

Thursday night: Partly cloudy. Low 18-25.

Friday: Partly sunny, some snow showers possible at night. High 29-36.

Saturday: Snow showers end early, some late-day sunny breaks, breezy. High 29-36.

Sunday: A mix of sun and clouds, breezy. High 26-33.

Astronomical winter doesn’t start for a few more weeks, but Mother Nature is giving us a preview this weekend.

It’s going to be rather chilly when you head outside Friday morning. Image provided by Weathermodels.com

An arctic cold front crossed the region this evening, producing some snow showers and squalls as it moved through. Behind it, much colder air is going to settle in tonight on gusty northwest winds. By Friday morning, temperatures will be in the single numbers and teens across most of the region, with some subzero readings possible in areas with fresh snowcover. Despite some sunshine on Friday, temperatures will only get into the 20s and lower 30s as winds die down, but clouds will quickly return ahead of another weak system. That system will pass south of the region Friday night and early Saturday, keeping the bulk of the precipitation offshore, but a trough extending from the system may produce a few snow showers. Across eastern Massachusetts and Cape Cod it should be mild enough for rain showers instead We’ll clear out Saturday night, then Sunday should be a decent day for early December, but another strong cold front moves through at night. This one will also produce some snow showers, and behind it we’ll turn rather cold again behind that front on Monday.

A couple of weak systems will impact our region this weekend. Loop provided by Tropical Tidbits.

Thursday night: Snow showers end in the evening, then becoming clear, except remaining partly to mostly cloudy across the Outer Cape. Breezy through the evening, winds start to diminish after midnight. Low 2-9. except 10-17 in urban areas and right along the coast.

Friday: Sunshine gives way to increasing afternoon clouds. High 22-29, a little milder across Cape Cod.

Friday night: Becoming cloudy, some snow showers possible after midnight, mainly south of the Mass Pike. Low 12-19 during the evening, a little milder in urban areas and right along the coast. Temperatures will slowly rise overnight.

Saturday: Plenty of clouds with snow showers likely inland, rain showers south and east of I-95. High 36-43.

Saturday night: Clearing. Low 19-26, a little milder across Cape Cod.

Sunday: Morning sun, then clouds return. High 33-40.

Sunday night: Plenty of clouds with some snow showers likely, some clearing late at night. Low 15-22.

Monday: Becoming mostly sunny, breezy. High 24-31, a little milder across Cape Cod.

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.

Monday: Sunshine and a few clouds. High 88-95, a little cooler along the coast.

Monday night: Clear skies. Low 65-72.

Tuesday: Plenty of sunshine. High 90-97, cooler along the coast.

Tuesday night: Clear to partly cloudy. Low 65-72.

Wednesday: Sunshine gives way to increasing afternoon clouds, chance for a late-day shower or thunderstorm, humid. High 86-93, cooler along the coast.

Wednesday night: Partly to mostly cloudy. Low 67-74.

Thursday: Partly sunny, showers and thunderstorms possible in the afternoon. High 83-90, cooler across the South Coast and Cape Cod.

Thursday night: Becoming clear. Low 62-69.

Friday: Sunny, drier. High 78-85, coolest near the coast.

Saturday: More sunshine. High 81-88, a little cooler along the coast.

Sunday: Mostly sunny. High 86-93, cooler along the coast.

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.

Heat and humidity remain in place to start the week, but they won’t last too long.

The heat index will be in the lower to middle 90s again this afternoon. Image provided by WeatherBell.

High pressure sits offshore today while a cold front begins to approach from the west. That’s a recipe for hot and humid conditions across our region today. We could see a few showers and thunderstorms pop up during the afternoon, but they should not be widespread. Tuesday is the transition day, though it will be very warm to hot and quite humid once again. Across parts of southeastern Massachusetts and Cape Cod there is the potential for some heavy downpours early in the day as what’s left of Tropical Storm Chantal moves past the area. Later, that cold front will move across the region, resulting in more widespread showers and thunderstorms, a few of which could be strong to severe across the interior.

A few showers and storms are possible today, but they are more likely late Tuesday into Tuesday evening. Loop provided by Weathermodels.com

The front settles south of the region, but likely remains close enough for plenty of clouds on Wednesday with cooler temperatures and possibly a few showers as well. A wave of low pressure riding along the front brings in more showers for Thursday. For Friday, a few lingering showers are possible, but some drier air will start to move in as high pressure starts to build in across southeastern Canada. Saturday should be mostly dry, but with an upper level low pressure area moving through we’ll see some clouds and possibly a shower or two in the afternoon. High pressure should move offshore for Sunday with dry and warmer weather expected.

A few models show the potential for heavy rain near the South Coast Thursday, but many show nothing more than scattered showers. Images provided by Pivotal Weather.
