The hype train has left the station and is barreling down the tracks at high speed. Unlike winter, when the hype is all about an impending snowstorm, this time, it’s about heat and humidity.

A ridge of high pressure in the upper levels of the atmosphere is going to set up shop across the eastern part of the nation later this week. This will result in very hot and humid weather for much of the eastern half of the nation, especially during the latter half of the week. Around here, it’s going to get hot, but will we get the extreme heat that many in the media are already proclaiming is a lock? We’re not quite so confident.

Before we get there, let’s talk about the first part of the week, which starts off with a rather nice day today with high pressure building in. We’ll have sunshine, seasonably warm temperatures, and moderate humidity levels. That high will move offshore on Tuesday, and a warm front extending from low pressure over the nation’s mid-section will approach our area. As the warm front moves in, some showers and thunderstorms are likely late in the day and into the evening. Some of these storms could be quite strong, with damaging winds and heavy downpours the main threats. We need all the rain we can get with the ongoing drought, but too much in a short-period results in areas of flooding.

Hot and humid air then settles in for Wednesday into Friday. Temperatures likely top 90 away from the South Coast on Wednesday, then Thursday and Friday appear to be the hottest days right now, but how hot will it get? Many forecast models are showing temperatures near or over 100, and all of the Facebook Forecasters (as well as many in the local media) have been quick to post these maps like it is locked in and a virtual certainty. Well, we’re here to tell you that it isn’t. Not yet at least. Not every model is showing widespread triple-digit heat. Seabreezes will keep coastal areas cooler. There’s also something that the models don’t handle that well that will have an impact. In this pattern, a common occurrence is for thunderstorms to develop across the Northern Plains and Upper Midwest, then ride along the jet stream over the top of that ridge, then dive southeastward towards New York and New England. These clusters usually end up around here late at night or first thing in the morning. Sometimes, it’s just weakening storms, sometimes they remain quite potent, even severe at times. The models are notoriously bad at picking these out more than 24 hours or so in advance. If the timing is a little off, and the clouds and/or showers hang around a little later into the morning, then it’s not going to get nearly as hot as the models are currently showing. It’s also worth mentioning that there won’t be a lot of relief at night, especially Wednesday Night and Thursday night, when temperatures will likely not drop below 70, and urban areas may not drop below 80.

Could some places reach 100 on Thursday? It’s possible, but not likely, at least for now. Image provided by WeatherBell.

As we get to the end of the week and the weekend, another complicating factor is a backdoor cold front dropping down from the north. Behind it, relatively cooler and drier air will settle in, with heat and humidity remaining in place to the south. When will this front move through? How far south does it get before it stalls out? Will it retreat northward as a warm front again before the weekend is over, bringing the hot and humid air back in? Will there be some showers and thunderstorms along this front? All of these factors result in a highly uncertain temperature forecast for later Friday and into the weekend. Since it’s Fourth of July weekend, there are lots of outdoor plans being made, and the forecast is an important part of that. For now, plan for it to be very warm, and keep an eye to the sky (or the radar), but be aware that the forecast still can change.

Will it still be hot for the Fourth of July or will it cool off a little? Images provided by Pivotal Weather.

Bottom line: Yes, it will get hot and humid for at least a few days later this week, but how hot and for how long remains uncertain, despite what you may see or read elsewhere. We’ll likely do a special blog post about this on Tuesday or Wednesday when things are a little more clear (hopefully), in addition to our normal Weekend Outlook on Thursday.

The first full weekend of summer will feature some nice weather for part, but not all of the weekend.

Showers and storms are likely tonight, possibly Friday afternoon, and again Saturday morning. Loop provided by weathermodels.com

Low pressure heading into southeastern Canada will send a warm front our way tonight. Clouds will thicken up ahead of it with some showers and thunderstorms likely overnight and into Friday morning as the front moves through. Warm and humid air then moves in for Friday, but how much sunshine we’ll see is a question and that has a big impact on the forecast. Obviously more sunshine will lead to warmer temperatures, but with a cold front approaching later in the day, we’ll have the potential for some severe weather. The more sunshine, the higher the risk. The biggest threats with any storms will be damaging winds, hail, and heavy downpours. We need all the rain we can get to help with the ongoing drought, but too much in a short period of time will result in flooding, as we saw in Fall River a few days ago.

Some severe thunderstorms are possible on Friday. Image provided by the Storm Prediction Center.

The front will slow down as it pushes offshore Friday night and another wave of low pressure will ride along it, bringing some showers to parts of Rhode Island and southeastern Massachusetts Saturday morning. They could get as far north as Route 44, but this is uncertain at this point. We should see clearing from northwest to southeast in the afternoon. High pressure builds in with drier weather for Sunday and Monday, though we could see a few popup showers or thunderstorms Sunday afternoon with an upper level disturbance moving across the Northeast.

Monday will be the warmest day of the next few. Image provided by WeatherBell.

Thursday night: Becoming mostly cloudy with showers and thunderstorms developing after midnight. Low 58-65.

Friday: Showers end in the morning, then intervals of clouds and sunshine with a chance for more showers and thunderstorms, some possibly strong to severe, late in the day. High 74-81.

Friday night: Mostly cloudy, any lingering showers end in the evening. Low 60-67.

Saturday: Morning clouds with showers across parts of Rhode Island and southeastern Massachusetts, then skies start to clear out from northwest to southeast. High 73-80.

Saturday night: Becoming partly cloudy. Low 56-63.

Sunday: Partly to mostly sunny, slight chance for an afternoon shower or thunderstorm. High 77-84.

Sunday night: Clear skies. Low 58-65.

Monday: Sunshine and a few clouds. High 81-88, cooler along the coast.

Astronomical summer begins this coming Sunday at 4:24AM, but summer weather will be here for much of the week.

Drier air will move in today with dewpoints dropping into the 50s and upper 40s. Image provided by weathermodels.com

We start off the week with a cold front pushing offshore this morning, taking the last of the showers and thunderstorms with it. Behind that front, high pressure builds in with seasonably mild temperatures, lower humidity, and a good amount of sunshine for today and Tuesday. By Wednesday, we’ll be watching a low pressure area heading into the Great Lakes. It will send a warm front our way at night, with some clouds moving in ahead of it, but the day itself will be mostly dry and seasonably warm. A few showers and thunderstorms may accompany the warm front Wednesday night, but the more noticeable effect will be an increase in humidity levels once again. Thursday could be an active day as low pressure moves into southern Canada, dragging a cold front across the region. With a warm and humid airmass in place, the front could trigger showers and thunderstorms during the daytime, with the potential for some of them to become strong to severe later in the day. Right now it’s just potential, but the ingredients are forecast by some of the models to be in place for some severe storms. This is something we’ll be keeping an eye on over the next few days. High pressure builds in behind the front with cooler and drier conditions for Friday and the weekend.

Drought conditions continue to worsen, and little help is expected this week. Image provided by the National Drought Mitigation Center.

Monday: Any lingering showers or thunderstorms end early, becoming partly to mostly sunny in the afternoon. High 78-85.

Monday night: Clear skies. Low 53-60.

Tuesday: Plenty of sunshine. High 74-81.

Tuesday night: Becoming partly cloudy. Low 54-61.

Wednesday: Partly sunny. High 75-82.

Wednesday night: Partly cloudy, chance for a late-night shower. Low 55-62.

Thursday: Partly sunny, breezy, becoming humid, showers and thunderstorms developing. High 76-83, cooler near the South Coast and Cape Cod.

Thursday night: Partly to mostly cloudy, showers and thunderstorms taper off in the evening. Low 61-68.

Friday: A mix of sun and clouds, breezy, not as humid. High 79-86.

Saturday: Mostly sunny, breezy. High 77-84.

Sunday: Sunshine and some afternoon clouds. High 75-82.

Very warm to hot weather will continue through the weekend, but the humidity won’t.

A heat advisory is in effect for much of the region away from the coastline through Friday evening. Image provided by the National Weather Service office in Norton, MA.

High pressure anchored off the East Coast will continue to pump hot and humid air into the region on southwest winds for another day or so, but some relief is on the way. A few showers and thunderstorms are possible through the evening, but they should gradually dissipate, leaving us with a warm and muggy night. Friday will also be hot and humid for most of the region, but a backdoor cold front will slip down the coast, bringing relief to coastal portions of Maine and New Hampshire, as well as the North Shore and likely the Boston area by midday. It probably won’t get too far inland, and may not get to the South Shore, but behind that front, temperatures will be in the 70s and lower 80s, compared to upper 80s and lower 90s inland. The South Coast and Cape Cod will be cooler as well, with southwest winds acting as a seabreeze. There could be a few widely scattered showers and thunderstorms in the afternoon, but most of the region will remain dry.

It’ll feel like the mid-to-upper 90s for much of the region Friday afternoon. Image provided by WeatherBell.

A stronger cold front moves in from the west Friday night, producing a few more showers and thunderstorms overnight. Behind that front we’ll clear out on Saturday. It will remain quite warm, with most places getting well into the 80s, but humidity levels will be much lower. Some clouds will start to filter back in on Sunday as another front moves toward the region, but again, most of the day will be dry and very warm. That front may produce a few showers and thunderstorms Sunday night, then we’ll see drier and cooler weather return for Monday.

Thursday night: Partly cloudy, any showers and thunderstorms taper off and end during the evening. Low 65-72.

Friday: A mix of sun and clouds, chance for a widely scattered shower or thunderstorm in the afternoon. High 86-93, cooler across the South Coast and Cape Cod. Coastal areas from Boston northward may turn cooler in the afternoon.

Friday night: Partly cloudy with a few showers and thunderstorms expected, skies start to clear out late at night. Low 63-70.

Saturday: Sun, sun, and more sun, much less humid. High 84-91, cooler across Cape Cod.

Saturday night: Clear to partly cloudy. Low 61-68.

Sunday: Sunshine slowly fades behind increasing clouds, breezy. High 85-92, cooler across Cape Cod.

Sunday night: Partly to mostly cloudy with a few showers and thunderstorms. Low 60-67.

Monday: A mix of sun and clouds. High 77-84.

We’ve got an early taste of summer before we get to Memorial Day Weekend.

Some record highs are possible on Tuesday. Image provided by WeatherBell.

Before we get to the forecast, we wanted to point out that this is blog post #1000 since we started on this long, strange journey, and it is posted just two days shy of the 10th anniversary of the first blog post. Before that StormHQ was just a Facebook page and a Twitter account, but now it’s been 10 years or sarcasm, information, commentary and of course weather forecasts, and for those of you still reading, we thank you very much. Now, onto the forecast.

A backdoor cold front has settled south of the region, so temperatures are will be on the cooler side today despite plenty of sunshine. Of course, cool is relative, as temperatures will be close to where the should be in mid-to-late May, but most places will be 10-20 degrees cooler than they were on Sunday. That front will lift back northward tonight, allowing the warm to hot and increasingly humid weather to return on Tuesday, with temperatures away from the South Coast getting well into the 80s, with some spots topping 90 degrees. We could see a few showers and thunderstorms during the afternoon, but the bulk of the region should remain dry. Wednesday starts off with sunshine, but clouds will quickly move in as a cold front heads our way. It will be another very warm and humid day with temperatures well into the 80s away from the South Coast, with a few places possibly reaching 90 again. The front will trigger showers and thunderstorms during the afternoon and evening, some of which could be strong to severe. Some of the stronger storms may produce heavy downpours, gusty winds, and hail. High pressure builds in behind the front with cooler and drier conditions for Thursday and Friday.

As for Memorial Day Weekend, there is a considerable amount of uncertainty at this point. We’ll have high pressure to the north, keeping temperatures on the cooler side, which a series of waves ride along a frontal system south of the region. That’s about all the models agree on at this point. Whether there is one wave or two, when do they move through, how far north does the rain get, how cool will it stay with cloudcover and/or rainfall. None of these are questions we can answer with any certainty at this point. Right now, it looks like Saturday and possibly Sunday will be the cooler and wetter days, but this is far from certain, and doesn’t mean that Monday will be a great day either for the holiday. We should have a better idea by the time we get to our Weekend Outlook on Thursday, and will take a deeper dive into it at that point.

Will Saturday be wet? The models don’t agree. Images provided by Pivotal Weather.

Monday: Partly to mostly sunny. High 75-82 south and west of Boston, 67-74 north of Boston, possibly a little cooler across the North Shore and Hew Hampshire Seacoast.

Monday night: Clear to partly cloudy. Low 58-65, except 50-57 across the North Shore, Hew Hampshire Seacoast, and Cape Cod.

Tuesday: Sunshine and some afternoon clouds, breezy, chance for an afternoon shower or thunderstorm. High 87-94, except 79-86 across the South Coast and 71-78 across Cape Cod.

Tuesday night: Partly cloudy. Low 64-71, cooler across Cape Cod.

Wednesday: Morning sun then increasing clouds with late-day showers and thunderstorms, some could be strong, breezy. High 84-91, except 76-83 across the South Coast and 68-75 across Cape Cod.

Wednesday night: Showers and storms end in the evening, becoming partly cloudy. Low 48-55.

Thursday: Partly sunny, much cooler. High 63-70.

Thursday night: Partly cloudy. Low 42-49.

Friday: Partly sunny. High 61-68.

Saturday: Mostly cloudy with a chance of showers. High 59-66.

Sunday: Mostly cloudy with a chance of showers. High 61-68.

Memorial Day: Intervals of clouds and sun. High 64-71.

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.

Humidity remains in place for several more days this week, but the heat will also make a comeback.

Dewpoints will get well into the 70s by midweek. Image provided by weathermodels.com

High pressure remains off to our southeast today, with a trough of low pressure moving toward the region. The result will be southwest winds bringing very warm and humid air into the region. As the trough gets nearer, we’ll see some showers and thunderstorms moving in late in the day and into the evening hours. While there could be a few strong storms, the timing will likely be a little too late in the day for any widespread severe weather. However, any storms that do form will likely be fairly slow-moving, so they could dump a lot of rain in localized areas, which could result in some flash flooding in spots. Now this won’t be like what we’ve see in Texas recently, and it probably won’t be as bad as we say south of Boston this past Thursday morning, but it’s something to keep in mind if you’ll be out and about this evening.

Thunderstorms may cross the region late this afternoon and evening. Loop provided by weathermodels.com

Some of the showers could linger into Tuesday morning across parts of eastern and southeastern Massachusetts until the trough moves offshore, but once it does, humidity levels won’t drop much, if at all, and we set the stage for some hot weather to return. Once the sun breaks out on Tuesday, temperatures should get well into the 80s, with dewpoints in the 60s, resulting in a heat index likely reaching the lower 90s in many spots in the afternoon. The heat and humidity really return for Wednesday and Thursday, with many locations getting near or above 90 degrees, but with dewpoints creeping up even higher, the heat index may approach or exceed 100 each afternoon. A couple of widely scattered showers and thunderstorms may provide a little relief on Wednesday, with coverage or showers and storms expanding a bit more on Thursday. Again, some of these storms could be slow-moving, so localized flash flooding is possible.

The heat index will get well into the 90s Wednesday afternoon. Image provided by WeatherBell.

Friday is the day with the biggest question marks at this point. A cold front will be heading towards the region, with very warm and very humid air remaining in place ahead of it. The question is – how warm? Some models give us enough sunshine to allow temperatures to get near or above 90 once again, others have enough cloudcover to keep us in the 80s. As the front moves in, showers and thunderstorms are likely. The timing of the front and the amount of sunshine we get will help determine whether we can expect any severe weather or not. High pressure builds in with cooler and drier weather for Saturday. Another system could start to move in by later Sunday, but it also could hold off until Sunday night or Monday. We’ll have a better idea of what to expect from that when we get to our Weekend Outlook, which will be published on Wednesday this week instead of Thursday.

Will Sunday be wet or stay dry? It’s too early to tell. Images provided by Pivotal Weather.

We’re also keeping an eye on the tropics. An area of disturbed weather currently off the Southeast coast is expected to drift towards northern Florida over the next few days, bringing some heavy rain to parts of the Sunshine State. After that, it should continue westward and into the northeastern Gulf. Some models show the potential for the system to develop as it moves westward across the northern Gulf, others don’t do much with it. Water temperatures are plenty warm, so that won’t be a factor. This is something we’ll be keeping an eye on over the next several days.

There is a chance a system could develop in the northern Gulf later this week. Image provided by the National Hurricane Center.

Monday: Some low clouds and fog early, then becoming partly sunny, humid, showers and thunderstorms possible late in the day. High 80-87, a little cooler across the South Coast and Cape Cod.

Monday night: Any lingering showers or storms end in the evening, remaining partly to mostly cloudy with another shower or two and some patchy fog possible. Low 66-73.

Tuesday: Morning clouds, maybe a shower or two across southeastern Massachusetts, then becoming partly to mostly sunny, still humid. High 83-90, a little cooler across the South Coast and Cape Cod.

Tuesday night: Partly cloudy. Low 65-72.

Wednesday: A mix of sun and clouds, very humid, slight chance for a pop-up shower or thunderstorm during the afternoon. High 86-93, cooler across the South Coast and Cape Cod.

Wednesday night: Partly to mostly cloudy and muggy with some patchy fog. Low 68-75.

Thursday: Partly sunny and quite humid, some afternoon and evening showers and thunderstorms possible, breezy in the afternoon. High 84-91, a little cooler across the South Coast and Cape Cod.

Thursday night: Partly cloudy, muggy. Low 69-76.

Friday: Partly sunny and humid with showers and thunderstorms developing in the afternoon, ending in the evening. High 86-93.

Saturday: A mix of sun and clouds, not as humid. High 78-85.

Sunday: Intervals of clouds and sun, chance for late-day showers and thunderstorms. High 79-86.

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.

Monday: Partly sunny, breezy, quite humid, chance for a few showers or thunderstorms. High 85-92, a little cooler across the South Coast and Cape Cod.

Monday night: Partly to mostly cloudy with areas of fog, some rain possible across southeastern Massachusetts and Cape Cod after midnight. Low 67-74.

Tuesday: A mix of sun and clouds, humid, showers and thunderstorms likely in the afternoon, a few could be strong. High 85-92, cooler across Cape Cod.

Tuesday night: Mostly cloudy, showers and storms taper off fog redevelops. Low 64-71.

Wednesday: Partly to mostly cloudy, a shower or two is possible, cooler. High 75-82.

Wednesday night: Plenty of clouds, some showers possible after midnight, mainly near the South Coast. Low 61-68.

Thursday: Mostly cloudy with scattered showers. High 74-81.

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

Friday: Mostly cloudy, a few more showers, mainly in the morning, some sunny breaks possible in the afternoon. High 72-79.

Saturday: Becoming partly sunny, slight chance for a pop-up shower. High 75-82.

Sunday: Intervals of clouds and sunshine. High 77-84.

As we reach the halfway point of the year, we also have Canada Day and Independence Day this week, so whichever you celebrate, enjoy as we’ll have some typical summertime weather for much of the upcoming week.

Canada and the United States will both be celebrating birthdays this week.

We start the week off with high pressure offshore resulting in a very warm to hot day today with increasing humidity levels as winds shift into the southwest. Tuesday looks like another warm and very humid day with dewpoints getting well into the 70s, but with an approaching cold front, we’ll see clouds and probably two rounds of showers and thunderstorms. The first batch likely moves through during the morning hours, but it’s the second batch that we’re keeping an eye on. The potential exists for some of the storms to become strong to severe, but that will depend on several factors. If we can get any sunshine after the first batch of storms, it will help to destabilize the atmosphere, whereas if it stays cloudy and thus cooler, the cold front will just produce some showers with only a few rumbles of thunder. We are expecting some sunshine to develop, so the other important factor is the timing of the front. A front that arrives late afternoon, during the maximum heating of the day will be more likely to produce severe weather than a front that arrives during the evening, when we are past the max heating of the day. Any storms that do form could produce heavy downpours and strong winds.

We’re looking at two rounds of thunderstorms on Tuesday. Loop provided by Weathermodels.com

Behind the front, high pressure builds back in with drier and more seasonable conditions for Wednesday and Thursday as highs will be mainly in the 80s, with dewpoints dropping into the 50s and lower 60s. Another disturbance may trigger a few showers and thunderstorms late Thursday, but high pressure returns for the Fourth of July and into Saturday with some spectacular summer weather, which shouldn’t cause any problems for any outdoor holiday celebrations. Another system could move in for Sunday, but that’s far from certain at this point.

Right now the weather for the Fourth looks picture perfect. Image provided by WeatherBell.

Monday: Some morning fog, otherwise partly to mostly sunny, humid. High 84-91, cooler along the coast and across Cape Cod.

Monday night: Becoming partly to mostly cloudy with fog redeveloping, especially along the coast. Some showers and thunderstorms are possible towards daybreak. Low 63-70.

Tuesday: Some showers and thunderstorms possible early, then intervals of clouds and sunshine, showers and thunderstorms may redevelop late in the day, breezy, very humid. High 82-89, cooler across the South Coast and Cape Cod.

Tuesday night: Showers and thunderstorms ending, some clearing after midnight. Low 64-71.

Wednesday: Becoming mostly sunny, less humid. High 81-88.

Wednesday night: Clear skies. Low 61-68.

Thursday: Sunshine and some afternoon clouds, chance for a late-day shower or thunderstorm. High 83-90, cooler across Cape Cod.

Thursday night: Chance for a shower or thunderstorm in the evening, otherwise becoming clear to partly cloudy. Low 59-66.

Friday: Mostly sunny, drier. High 76-83.

Saturday: A mix of sun and clouds. High 79-86.

Sunday: Partly sunny, more humid, breezy, chance for a few showers or thunderstorms. High 86-93, cooler across Cape Cod.

We’ve got a fairly complicated forecast for the final days of Spring and initial days of Summer.

The heat index will reach the middle to upper 90s across much of the region on Thursday. Image provided by WeatherBell.

A warm and humid airmass has settled into the region, and it will be here into Thursday. We’ll have plenty of clouds through the evening with a few showers and possibly a rumble of thunder as a weak disturbance moves across the region. These showers should end before midnight, then we’ll see some fog developing. Once the fog burns off Thursday morning a hot and humid day is expected under partly to mostly sunny skies. Gusty southwest winds will help send temperatures into the upper 80s and lower 90s in much of the region, except along the South Coast and Cape Cod, where winds off the water will keep temperatures a little cooler. Dewpoints well get into the 60s and lower 70s, resulting in the heat index reaching the middle to upper 90s in many areas. A Heat Advisory has been issued for parts of the region as a result.

Severe weather is possible in the Northeast Thursday with damaging winds the greatest threat. Image provided by Pivotal Weather.

A cold front will move across the region late in the day, triggering some showers and thunderstorms during the late afternoon and evening. A few of these storms may produce strong winds, heavy downpours and some hail, but it looks like the best chance for severe storms will be off to our west. If the front were to move in a little faster than we currently expect, the odds for severe weather would rise, since it would be arriving around the time of maximum heating. Behind the front, drier air settles in for Friday, and while it won’t be as hot, it will still be quite warm. As we get to Saturday, it looks like we will finally break our streak of wet Saturdays with sunshine, mild temperatures, and lower humidity, but that doesn’t mean the entire weekend will be dry.

A cluster of thunderstorms could rumble across the region before daybreak Sunday, Loop provided by Tropical Tidbits.

Forecast models have been showing the potential for a cluster of potent thunderstorms to develop across the Northern Plains Friday evening which would then race across the Northern Great Lakes on Saturday before diving into New England after midnight Saturday night. While they should be weakening by the time they get here, don’t be surprised if you’re awakened early Sunday morning by frequent lightning and some heavy downpours. Once those storms move offshore, skies will become partly to mostly sunny again with another dry and warm day expected. Things change again by Monday. A ridge of high pressure will start to build in, resulting in heat and humidity returning on Monday, and possibly for at least a few more days beyond that heading into next week. We’ll have more on that in our Weekly Outlook early Monday morning.
