Some fairly typical summertime weather continues for a few more days, but relief arrives at the end of the week.

The cold front that moved through yesterday bringing some drier air into the region will lift back northward as a warm front today, allowing the humidity to return. As the humid air returns we could see a few showers and thunderstorms this evening, but they’ll be weakening as they move in from the west, and might not make it all the way to the coastline. Another weak cold front moves through early Tuesday, with sunshine and drier weather for Tuesday and Wednesday. It will be hazy at times as more high-level smoke from wildfires in the West drifts into the region. Thursday will see a stronger cold front move into the region. It’ll be warm and humid ahead of it, with more showers and thunderstorms likely. The timing of the front will be key in determining whether we get any severe weather. Right now, it looks like the front moves through by early afternoon, but if it were delayed by a few hours, allowing additional time for the atmosphere to become unstable, severe weather would become more likely. This is something we’ll be keeping an eye on for the next few days. Behind the front, cooler and drier air settles in for Friday and Saturday. We’ll be watching another system moving out of the Midwest that could bring in some showers and thunderstorms later on Sunday.

A Bermuda High will remain anchored off the East Coast through the weekend and into early next week. That will result in very warm to hot and humid conditions with a daily chance for showers and thunderstorms. It won’t be as hot as the heat wave we had in early July, but it will be quite humid, so the heat index will remain uncomfortable. We’re not expecting widespread severe weather, but some of the thunderstorms that pop up each afternoon could produce heavy downpours and gusty winds.

Some typical summertime weather is expected for the first full week of the last month of meteorological summer.
Heavy rainfall is possible across the interior today, with some flash flooding possible. Image provided by Iowa Environmental Mesonet.
The week starts off on a wet note with a cold front approaching the region. A warm and humid airmass will be in place with gusty southwest winds at times, especially across eastern Massachusetts. Showers and a few thunderstorms are likely through the morning, some of which could be locally heavy. Some pockets of flash flooding are possible, as the ground remains fairly saturated from recent rainfall, which has pretty much taken care of the drought. We’re still in a long-term rainfall deficit, but the drought itself is essentially gone. The showers will taper off, then we may see some sunny breaks develop. As the cold front moves in during the afternoon, it will trigger a second round of showers and thunderstorms. Depending on how much sun we get, some of those storms could become severe.

The front moves offshore tonight then high pressure builds in with drier weather for Tuesday. High pressure then sets up residence off the East Coast, resulting in very warm to hot and humid weather from Wednesday through the weekend. As is typical of a warm and humid airmass in the summer, we’ll see a daily chance for pop-up showers and thunderstorms, especially towards the end of the week and into the weekend. Widespread severe weather is not expected, but any of these storms could produce heavy downpours and gusty winds.

Saturday: Partly sunny, chance for afternoon showers or thunderstorms. High 83-90.
Sunday: A mix of sun and clouds, chance for a shower or thunderstorm. High 84-91.
Heat and humidity will return this week, but not to the extent that we experienced recently.

High pressure slides offshore today, with increasing temperatures and humidity levels. A pop-up shower or thunderstorm can’t be ruled out, but they’ll be few and far between. Tuesday looks even hotter, except along the South Coast and Cape Cod, with southwest winds act as a seabreeze. A cold front moves through early Wednesday with little fanfare, but it will bring some drier air into the region. It will remain hot, and with northwest winds, the heat will get all the way down to the South Coast. Another front moves through on Thursday, possibly producing a shower or thunderstorm, but most places will remain dry, which means we don’t get much drought relief. Cooler air settles in for Friday. The weekend is a bit uncertain at this point. A low pressure system may move out of the Great Lakes and towards New England with some showers and thunderstorms at some point, but the timing, and whether the system even materializes, is still a question.

Hot and humid weather will make a brief return, but most of the weekend looks rather nice.
It will feel like it is in the 90s across most of the region Thursday afternoon. Image provided by WeatherBell.
High pressure sitting offshore has brought high humidity back to the region along with very warm to hot conditions, but it won’t last too long. A cold front will cross the region on Friday, with showers and thunderstorms ahead of it during the afternoon and evening. We’re not expecting widespread severe weather but some of the storms could produce heavy rainfall and gusty winds. The front pushes offshore Friday night, though it could linger near the South Coast for a while, keeping some clouds and possibly a few showers into early Saturday, otherwise, high pressure builds back in with lower humidity and seasonable warm conditions for the rest of the weekend and Monday.
Dewpoints will drop into the 50s behind the front on Saturday. Image provided by Weathermodels.com

Friday: A mix of sun and clouds, showers and thunderstorms develop in the afternoon. High 82-89.
Friday night: Showers and thunderstorms taper off and end, becoming partly cloudy across southern New Hampshire and northern Massachusetts. Low 63-70.
Saturday: Becoming partly to mostly sunny, less humid. High 77-84, a little cooler across Cape Cod.
You’ve heard us use the phrase “When in drought, leave it out” in relation to rainfall plenty of times. There is a corollary to that phrase – “Droughts end in floods”, which we’re going to use for the next few days.

The front that brought an end to the heat Saturday night has stalled out south of New England, and a wave of low pressure will ride along it over the next day or so. This will result in periods of rain, some of it heavy at times later today into a good chunk of Tuesday, mainly south of the Mass Pike. Many of the forecast models are showing the potential for 2-4 inches of rain, with amounts in excess of 6 inches possible. Pinpointing where these tropical downpours will be the heaviest is a fool’s errand, but that much rain in a short period of time, even with the ongoing drought, will result in areas of flooding. That’s why Flood Watches have been issues for much of Rhode Island and southeastern Massachusetts, as this is where the heaviest rain is expected. The question is, how much rain falls north of the Mass Pike? While there are some models that bring the heavy rain all the way into southern New Hampshire, many of them have the amounts taper off quickly north of the Pike, with little rainfall once you get into southern New Hampshire. With the cloudcover and rainfall, temperatures will be quite cool, with many places staying in the 60s, especially on Tuesday, The showers wind down Tuesday night, then high pressure builds in with gradually improving conditions on Wednesday, though temperatures will remain below normal. Very warm weather returns for Thursday as high pressure moves offshore, with some places getting back to 90. This heat will be short-lived, as another cold front moves through on Friday with some showers and thunderstorms. High pressure brings cooler and drier weather in for Saturday, with temperatures turning a bit warmer again on Sunday.
Many of the models are forecasting some very heavy rainfall, especially south of the Mass Pike. Images provided by Pivotal Weather.
Monday: Cloudy with periods of rain and showers, mostly south of the Mass Pike. High 69-76.
Monday night: Rain likely, heavy at times south of the Mass Pike. Low 57-64.
Tuesday: Rain during the morning, tapering off to showers in the afternoon. High 64-71.
Tuesday night: Showers ending during the evening, some clearing may start late at night, mainly north and west of Boston. Low 55-62.
Wednesday: Becoming partly to mostly sunny. High 75-82, a little cooler near the coast.
Wednesday night: Clear to partly cloudy. Low 61-68.
Thursday: Sunshine and some afternoon clouds. High 85-92, cooler near the South Coast and Cape Cod.
Thursday night: Partly cloudy. Low 65-72.
Friday: Partly sunny with some showers and thunderstorms likely in the afternoon. High 83-90.
As we get ready to celebrate America’s 250th, some very hot weather will be here for a few days.
Friday will be another hot day before relief starts moving in on Saturday. Image provided by weathermodels.com
A ridge of high pressure continues to provide the eastern half of the nation with hot and humid conditions into Saturday. Daytime temperatures well into the 90s, combined with dewpoints in the 60s and lower 70s, will make it feel like 100-105 at times. Not much relief comes at night, with lows only in the 70s tonight through Friday night, with places like downtown Boston possibly not falling below 80. A few widely scattered showers and thunderstorms are possible tonight, but they’ll be a bit more numerous Friday afternoon and evening. The Fourth of July is the transition day, and unfortunately, with plenty of outdoor gatherings planned, they could be impacted. A cold front will drop southward, but ahead of it, we’re going to have another hot and humid day, with most places topping 90 again. However, the front will trigger some showers and thunderstorms, especially during the afternoon. Some of these storms may produce heavy downpours and gusty winds, so keep an eye to the sky (or the radar) if you’ll be outside. Hopefully the storms will end before evening, allowing many fireworks celebrations to proceed. Welcome relief arrives on Sunday with cooler and drier air. Cool is a relative term, and most places will still be in the 80s, which is right around or a little above normal. Monday is the day with the most uncertainty at this point. That front will stall out south of New England, and as we get to Monday a wave of low pressure will ride along it. Some models bring in some showers with the wave during the afternoon, some wait until nighttime. We’re going to be cautiously optimistic that most if the day remains dry at this point, but that is far from guaranteed.
Will the rain arrive Monday afternoon or wait until nightfall? Images provided by Pivotal Weather.
Thursday night: Mostly clear, slight chance for a shower or thunderstorm during the evening. Low 72-79.
Friday: Sunshine and a few clouds, a late-day shower or thunderstorm is possible. High 93-100, cooler across Cape Cod.

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.
Some warm and muggy nights are likely later this week with lows in the 70s. Image provided by Weathermodels.com
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.

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

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.

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.

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.

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.
Some typical June weather is expected for much of the upcoming week.

We start the week off on a cool note with high pressure building in from Canada. We’ll have plenty of sunshine today, but east to northeast winds off the still cool Atlantic will keep temperatures on the cool side today, especially near the coastline. As the high slides southward on Tuesday and anchors itself off the East Coast, a ridge of high pressure will start build in aloft, resulting in a warming trend. With sunshine continuing on Tuesday, southwest winds will help many locations top 80 away from the South Coast and Cape Cod. Much of the remainder of the week will feature hot and increasingly humid conditions, with a daily chance for a few showers and thunderstorms as weak disturbances cross the region. The exception could be later Thursday into part of Friday, when we may see a backdoor cold front trying to bring in some cooler air, especially along the coast. This is far from a certainty, and even if it does occur, it would lift northward again by Saturday, allowing the heat and humidity to return. A stronger cold front may begin to move in from the west on Sunday.
Friday could be quite toasty, but it also could be considerably cooler near the east coast. Imaged provided by Pivotal Weather.
Monday: Sunshine and a few clouds. High 73-80, a little cooler along the coast and across Cape Cod.
Monday night: Clear skies. Low 50-57.
