DAYS 1-5 (JULY 16-20)
Heading into the summer I had been debating with myself if, after a frequently wet spring, we’d see a summer that resembled 1983, blasting into much drier weather and a lot of heat, or something more like the solar minimum summers that my colleague talked about, lacking sustained heat and having occasional northwest flow thunderstorm opportunities. So far, it’s been a little more the latter, but a taste of the former is on the way as we get into a blast of heat Friday that will probably last at least a few days. But before there, we have some other weather to go through, including another beautiful summer day today with fairly low humidity and a fair amount of sunshine. One change to the previous forecast is that the moisture associated with the remains of Barry are moving faster than was original expected, and will also be elongated, so this means unsettled weather arrives sooner during tomorrow (not waiting until late at night) and will still last into Thursday. But also another difference, previously thinking we’d be on the warmer more humid side of a boundary Thursday, that has now changed and it looks like a frontal boundary will be pulled southward, taking the edge off what would have been oppressive humidity and also limiting how high the temperature will get with more cloud cover and a generally onshore (easterly) air flow across the region. And then…… well I already mentioned that, but things flip around and shift so that the heat and humidity arrives Friday, but while the heat remains and probably peaks Saturday, it may dry out somewhat due to a downsloping westerly wind across the region.
Forecast details…
TODAY: Mostly sunny. Highs 83-90. Wind SW up to 10 MPH.
TONIGHT: Partly cloudy. More humid. Lows 65-72. Wind SW up to 10 MPH.
WEDNESDAY: Partly sunny morning. Variably cloudy with scattered to numerous showers and thunderstorms arriving / developing afternoon. Humid. Highs 83-90. Wind SW up to 10 MPH.
WEDNESDAY NIGHT: Mostly cloudy. Numerous showers/thunderstorms. Humid. Lows 66-73. Wind light variable.
THURSDAY: Mostly cloudy. Showers likely. Chance of thunderstorms. Humid. Highs 73-80. Wind E 5-15 MPH.
THURSDAY NIGHT: Variably cloudy. Areas of fog. Humid. Lows 63-70. Wind light S.
FRIDAY: Partly sunny. Very humid. Highs 81-88 Cape Cod, 88-95 elsewhere. Wind SW 5-15 MPH.
FRIDAY NIGHT: Partly cloudy. Humid. Lows 72-79. Wind WSW up to 10 MPH.
SATURDAY: Mostly sunny. Slightly less humid. Highs 92-99, cooler Cape Cod. Wind W 5-15 MPH.

DAYS 6-10 (JULY 21-25)
The overall pattern will be westerly air flow aloft but with the upper ridge backing up through the Midwest. We start out rather hot then trend back toward more seasonable. Limited opportunities for showers and thunderstorms with dry weather being dominant.

DAYS 11-15 (JULY 26-30)
Heading into the final days of July expect a pattern in which the ridge center backs up a little more toward the upper Plains. This allows a little bit more of a dip in the jet stream into the Great Lakes and Northeast which won’t put us in a cool pattern, keeping it more typical for the season, but increasing the risk of shower and thunderstorm threat somewhat.

7:11AM

DAYS 1-5 (JULY 15-19)
An area of high pressure moves in from the west today providing warm but dry air. The high slips to the south with a little more in the way of humidity but still fairly comfortable Tuesday, but when a warm front comes across the region in the evening you’ll notice the humidity start to elevate more significantly, setting up 3 classic humid summer days. In the warm sector between behind that warm front and ahead of a cold front we run risk of a few showers and thunderstorms Wednesday, then with the front in the area and the remnant moisture from Barry coming across the region Thursday, that will be when we see the most numerous shower and thunderstorm activity. The weather will dry out Friday, but the air will not, and it will be a hot and humid day but without the thunderstorm risk.
Forecast details…
TODAY: Mostly sunny. Highs 80-87, coolest coast. Wind light variable with sea breezes.
TONIGHT: Mostly clear. Lows 60-67. Wind light W.
TUESDAY: Partly sunny. More humid. Highs 82-89. Wind W 5-15 MPH.
TUESDAY NIGHT: Partly cloudy. Humid. Lows 63-70. Wind W up to 10 MPH.
WEDNESDAY: Partly sunny. Isolated thunderstorms possible mainly late-day. Humid. Highs 88-95, cooler South Coast / Cape Cod. Wind WSW 5-15 MPH.
WEDNESDAY NIGHT: Partly to mostly cloudy. Showers and thunderstorms becoming more likely late at night. Humid. Lows 68-75. Wind SW 5-15 MPH.
THURSDAY: Variably cloudy. Showers/thunderstorms likely. Very humid. Highs 80-87. Wind variable 5-15 MPH.
THURSDAY NIGHT: Partly cloudy. A lingering shower or thunderstorm possible evening. Very humid. Lows 73-80. Wind W 5-15 MPH.
FRIDAY: Mostly sunny. Humid. Highs 90-97, slightly cooler Cape Cod. Wind W 5-15 MPH.

DAYS 6-10 (JULY 20-24)
July 20-21 weekend will be very warm to hot but with lowering humidity and only a risk of a passing shower/thunderstorm later on July 20. Generally west to east flow pattern will dominate with mean high pressure ridge Midwest to Upper Plains with temperatures slightly above normal to near normal later in the period, plenty of dry weather but also the risk of a passing shower or thunderstorm at times.

DAYS 11-15 (JULY 25-29)
Overall pattern similar, but a slightly westward movement of the high pressure ridge in the center may increase the risk of showers and thunderstorms slightly here, though still not a return to a very wet pattern. Much of the time would be rain-free. Temperatures closer to normal.

7:26AM

DAYS 1-5 (JULY 14-18)
A couple of fabulous summer days to end the weekend, and start the new work week, or extend the weekend if you’re lucky enough to be off. The only real rain-threat in the next 5 days will be the potential passage of the moisture formerly associated with Barry in the Gulf of Mexico, and that would be around Thursday. The forecast issued yesterday is essentially unchanged, so not much new follows this text.
Forecast details…
TODAY: Mostly sunny to partly cloudy. Less humid. Highs 83-90, coolest Cape Cod. Wind W 5-15 MPH.
TONIGHT: Partly cloudy early, then clearing. Lows 62-69. Wind light W.
MONDAY: Mostly sunny. Highs 80-87, coolest coast. Wind light variable with sea breezes.
MONDAY NIGHT: Mostly clear. Lows 60-67. Wind light W.
TUESDAY: Partly sunny. More humid. Highs 82-89. Wind W 5-15 MPH.
TUESDAY NIGHT: Partly cloudy. Humid. Lows 63-70. Wind W up to 10 MPH.
WEDNESDAY: Partly sunny. Isolated thunderstorms possible mainly late-day. Humid. Highs 88-95, cooler South Coast / Cape Cod. Wind WSW 5-15 MPH.
WEDNESDAY NIGHT: Partly to mostly cloudy. Showers and thunderstorms becoming more likely late at night. Humid. Lows 68-75. Wind SW 5-15 MPH.
THURSDAY: Variably cloudy. Showers/thunderstorms likely. Very humid. Highs 80-87. Wind variable 5-15 MPH.

DAYS 6-10 (JULY 19-23)
General west to east flow with mean high pressure ridge position in the Midwest to upper Plains. Shower and thunderstorm threats will depend on timing of disturbances. Temperatures generally above normal.

DAYS 11-15 (JULY 24-28)
Overall pattern similar, but a slightly westward movement of the high pressure ridge in the center may increase the risk of showers and thunderstorms slightly here, though still not a return to a very wet pattern. Much of the time would be rain-free. Temperatures closer to normal.

8:08AM

DAYS 1-5 (JULY 13-17)
Our wet weather interruptions have been minimal so far in July and we’re also doing it without long stretches of high heat and humidity. The overall pattern continues this way but there will be a bit more heat added to things as we get to the end of this 5-day period, transporting some heat from the upper Midwest to New England via westerly air flow, not a building Bermuda High that we saw so much of last summer. We will continue with limited rain chances through the 5-day period, with showers produced by a low pressure trough likely staying north of the region Sunday, and only a few isolated thunderstorms possible with the arrival of our heat by the middle of next week. Otherwise, high pressure will be in control with generally dry weather. You will still feel some humidity in the air today as it takes a couple days for some drier air to filter down from Canada.
Forecast details…
TODAY: Mostly sunny. Moderately humid. Highs 83-90, coolest Cape Cod. Wind W 5-15 MPH.
TONIGHT: Mostly clear. Moderately humid. Lows 63-70. Wind W 5-15 MPH.
SUNDAY: Partly cloudy. Less humid. Highs 83-90, coolest Cape Cod. Wind W 5-15 MPH.
SUNDAY NIGHT: Partly cloudy early, then clearing. Lows 62-69. Wind light W.
MONDAY: Mostly sunny. Highs 80-87, coolest coast. Wind light variable with sea breezes.
MONDAY NIGHT: Mostly clear. Lows 60-67. Wind light W.
TUESDAY: Partly sunny. More humid. Highs 82-89. Wind W 5-15 MPH.
TUESDAY NIGHT: Partly cloudy. Humid. Lows 63-70. Wind W up to 10 MPH.
WEDNESDAY: Partly sunny. Isolated thunderstorms possible mainly late-day. Humid. Highs 88-95, cooler South Coast / Cape Cod. Wind WSW 5-15 MPH.

DAYS 6-10 (JULY 18-22)
General west to east flow with mean high pressure ridge position in the Midwest to upper Plains. Shower and thunderstorm threats will depend on timing of disturbances. There will be a couple during the period. We will also need to watch the remnant moisture from T.S. Barry to see if any of that gets involved. If so, target date remains at the start of the period, July 18. Temperatures will run above normal for the period.

DAYS 11-15 (JULY 23-27)
Overall pattern similar, though ridge center may tend to be further west (Plains) versus east (Midwest). Will have to watch for shower and thunderstorm threats based on passing disturbances but overall much of the time will be rain-free.

7:23AM

DAYS 1-5 (JULY 12-16)
It’s a muggy morning as the overnight heavy rainfall tapers to showers, a few of which are also on the heavier side, but this main area of moisture will be offshore soon and as we break clouds for some sun it will fuel a few more shower and storm threats during the day, because we still have to wait for a cold front to cross the region. This front is not the borderline to a very dry air mass, in fact it will take a few days for it to fully dry out, so even with fair weather upcoming for the weekend and Monday, it will start out somewhat humid Saturday then gradually lessen. In fact it is a weak trough moving through the region Sunday that will deliver the drier air from Canada. This trough will probably not produce any precipitation, however, with its shower activity likely remaining well to the north. By Tuesday of next week, we will introduce some increased humidity and perhaps the risk for a shower or thunderstorm again by the end of that day.
Forecast details…
TODAY: Cloudy start with areas of fog and showers, a few heavy. Becoming partly sunny with one or two passing showers/thunderstorms possible midday and afternoon. Humid. Highs 80-87, coolest South Coast. Wind SW to W 5-15 MPH with higher gusts.
TONIGHT: Clearing. Patchy fog. Slightly less humid. Lows 63-70. Wind W 5-15 MPH.
SATURDAY: Mostly sunny. Moderately humid. Highs 83-90, coolest Cape Cod. Wind W 5-15 MPH.
SATURDAY NIGHT: Mostly clear. Moderately humid. Lows 63-70. Wind W 5-15 MPH.
SUNDAY: Partly sunny. Less humid. Highs 83-90, coolest Cape Cod. Wind W 5-15 MPH.
SUNDAY NIGHT: Partly cloudy early, then clearing. Lows 62-69. Wind light W.
MONDAY: Mostly sunny. Highs 78-85, coolest coast. Wind light variable.
MONDAY NIGHT: Mostly clear. Lows 60-67. Wind light W.
TUESDAY: Partly sunny. More humid. Highs 82-89. Wind W 5-15 MPH.

DAYS 6-10 (JULY 17-21)
General west to east flow with mean high pressure ridge position in the Midwest to upper Plains. Shower and thunderstorm threats will depend on timing of disturbances. There will be a couple during the period. We will also need to watch the remnant moisture from T.S. Barry to see if any of that gets involved. If so, target date is July 18. May be briefly hotter to start the period then more seasonably warm.

DAYS 11-15 (JULY 22-26)
Overall pattern similar, though ridge center may tend to be further west (Plains) versus east (Midwest). Will have to watch for shower and thunderstorm threats based on passing disturbances but overall much of the time will be rain-free.

7:23AM

DAYS 1-5 (JULY 11-15)
Mid July. Here we are. No heatwaves yet. But we didn’t expect that the chance of heatwaves (3 or more days of 90 degree or higher high temperatures) would be supported in this weather pattern. But we will see some hot weather in the pattern. Do we finally squeak out a heatwave in the next several days in any location? We’ll see. But odds are against it during this 5-day period. High altitude smoke remains in the sky from Canadian fires, and we can see that in and out of the region for several days to come as the upper winds shift around. Down here in the part of the atmosphere that impacts us more directly, we will feel an increase in humidity today, especially as a boundary passes the region this afternoon. Along this boundary, a shower or thunderstorm may pop up, with the greatest risk in north central to northeastern MA, and southern NH. Areas to the south will probably see nothing. Tonight, a trough will cross the region from west to east and kick off one or 2 line-clusters of showers/thunderstorms. We’ll have to watch these for torrential downpours, and there is a risk that one or 2 of the storms could produce some gusty winds. A cold front will cross the region on Friday and bring another risk of a passing shower/storm 1 or 2 times during the day, but the threat should be over by or before evening as drier and more stable air arrives from the west. This will set up a nice Saturday with high pressure in control. This high will sink to the south a little Sunday as a low pressure area crosses southeastern Canada and sends a trough through the region, but most of the shower and thunderstorm activity with this will be in northern New England, with only a slight risk of one making it down into parts of southern New England, so don’t cancel any outdoor plans for Sunday based on that minimal threat. A warm front approaches later Monday and may bring some cloudiness back but otherwise so far that looks like a nice day overall.
Forecast details…
TODAY: Partly sunny. Risk of a passing shower/thunderstorm north central and northeastern MA and southern NH mainly between 1PM and 4PM. Increasingly humid. Highs 86-91, except cooler South Coast. Wind SW 5-15 MPH, a few higher gusts.
TONIGHT: Mostly cloudy. Showers/thunderstorms probable after 9PM. Humid. Lows 67-74. Wind SW 5-15 MPH, higher gusts.
FRIDAY: Variably cloudy. A couple passing showers/thunderstorms possible. Humid. Highs 80-87, coolest South Coast. Wind SW to W 5-15 MPH with higher gusts.
FRIDAY NIGHT: Clearing. Patchy fog. Lowering humidity. Lows 63-70. Wind W 5-15 MPH.
SATURDAY: Mostly sunny. Highs 83-90, coolest Cape Cod. Wind W 5-15 MPH.
SATURDAY NIGHT: Mostly clear. Lows 63-70. Wind W 5-15 MPH.
SUNDAY: Partly sunny. Slight risk of a passing shower/thunderstorm favoring northern MA and southern NH. Highs 83-90, coolest Cape Cod. Wind W 5-15 MPH.
SUNDAY NIGHT: Partly cloudy early, then clearing. Lows 62-69. Wind light W.
MONDAY: Increasing cloudiness. Highs 78-85, coolest coast. Wind light variable.

DAYS 6-10 (JULY 16-20)
General west to east flow with mean high pressure ridge position in the Midwest to upper Plains. Shower and thunderstorm threats will depend on timing of disturbances. There will be a couple during the period. Something to watch for is whether or not any moisture associated with a tropical system currently in the Gulf of Mexico gets involved in our shower/thunderstorm threat around the middle of this period. Temperatures will average a little above normal overall. A brief spike of higher heat is possible.

DAYS 11-15 (JULY 21-25)
Overall pattern similar, though ridge center may tend to be further west (Plains) versus east (Midwest). Will have to watch for shower and thunderstorm threats based on passing disturbances but overall much of the time will be rain-free.

7:21AM

DAYS 1-5 (JULY 10-14)
Another day of smoke in the atmosphere from Canada. It’s not that Canada is having their worse fire season ever, it’s that our weather pattern has been one that transports that smoke down this way a little more than we have seen in other recent years, so just in case the media gets bored and decides to try to convince you that Canada’s burning down … it’s not. So other than high altitude smoke, what’s up? More of the same, seasonable heat and a bump up in humidity the next couple days, but not to unbearable levels just yet. That will reserve itself to a number of hours on Friday when we will also introduce the risk of showers and thunderstorms as a cold front traverses the area. Some guidance has indicated that a few thunderstorms may also develop on the leading edge of the more humid air which will pass the region Thursday, but I’m not going to buy into that at this time, just adding some more cloudiness to the forecast. Even Friday’s activity may end up rather limited as the conditions, though coming in waves, may not be all that supportive of organized or strong showers and storms. But any time you have some heat, some humidity, and a front, you should keep an eye on things just in case. Weekend? Looking great for the most part. A high pressure area returns fair and less humid weather to the region Saturday, and a weak disturbance may cause a passing shower or storm Sunday but otherwise that looks like a mainly dry day as well.
Forecast details…
TODAY: Smoke-filtered sunshine. Highs 85-92, except cooler Cape Cod. Wind W 5-15 MPH.
TONIGHT: Partly cloudy. Lows 66-73. Wind SW 5-15 MPH.
THURSDAY: Partly sunny. More humid. Highs 86-91, cooler South Coast. Wind SW 10-20 MPH.
THURSDAY NIGHT: Mostly cloudy. Showers/thunderstorms possible after midnight. Humid. Lows 67-74. Wind SW 5-15 MPH, higher gusts.
FRIDAY: Variably cloudy. Showers/thunderstorms probable at times. Muggy. Highs 78-85, coolest South Coast. Wind SW 5-15 MPH with higher gusts.
FRIDAY NIGHT: Clearing. Patchy fog. Lowering humidity. Lows 63-70. Wind W 5-15 MPH.
SATURDAY: Mostly sunny. Highs 83-90, coolest Cape Cod. Wind W 5-15 MPH.
SATURDAY NIGHT: Mostly clear. Lows 63-70. Wind W 5-15 MPH.
SUNDAY: Partly sunny. Risk of a passing shower/thunderstorm. Highs 83-90, coolest Cape Cod. Wind W 5-15 MPH.

DAYS 6-10 (JULY 15-19)
General west to east flow with mean high pressure ridge position in the Midwest. Minimal threat of showers/thunderstorms at times, with a risk later July 15 into July 16, and perhaps about July 19, based on the timing of systems in the jet stream. Temperatures in this pattern should average somewhat above normal, but without prolonged high heat.

DAYS 11-15 (JULY 20-24)
High pressure ridge may slide eastward for the July 20-21 weekend resulting in more heat, then head back to the Midwest and Upper Plains allowing the heat to ease again after that. Shower/thunderstorm threats will exist a couple times with passing disturbances, but it’s impossible to time such threats this far in advance.

7:19AM

DAYS 1-5 (JULY 9-13)
High pressure dominates the weather through midweek with warm to marginally hot weather and a gradual increase in humidity, but staying below oppressive levels through Thursday. We’ll see some high altitude smoke, as we have periodically, due to an active Canadian fire season. By Friday, it will be muggyfest 2019 as some tropical air gets in, combined with the passage of a low pressure area and cold front, which will result in a showery and possibly thunderstormy day. Not looking for severe weather, at least in a widespread sense, but we’ll have to watch the system for that. Heavy downpours are more likely to be the issue. A few days to iron those details out. Dry weather and lower humidity will be back in time for the start of the weekend.
Forecast details…
TODAY: Sunny. Patchy smoke aloft. Highs 81-88. Wind W up to 10 MPH but still some light coastal sea breezes.
TONIGHT: Clear but some smoke aloft. Lows 58-65. Wind light W.
WEDNESDAY: Smoke-filtered sunshine. Highs 85-92, except cooler Cape Cod. Wind W 5-15 MPH.
WEDNESDAY NIGHT: Partly cloudy. Lows 66-73. Wind SW 5-15 MPH.
THURSDAY: Partly sunny. More humid. Highs 86-91, cooler South Coast. Wind SW 10-20 MPH.
THURSDAY NIGHT: Mostly cloudy. Showers/thunderstorms possible after midnight. Humid. Lows 67-74. Wind SW 5-15 MPH, higher gusts.
FRIDAY: Variably cloudy. Showers/thunderstorms likely. Muggy. Highs 78-85, coolest South Coast. Wind SW 5-15 MPH with higher gusts.
FRIDAY NIGHT: Clearing. Patchy fog. Lowering humidity. Lows 63-70. Wind W 5-15 MPH.
SATURDAY: Mostly sunny. Highs 80-87, coolest Cape Cod. Wind W 5-15 MPH.

DAYS 6-10 (JULY 14-18)
General west to east flow with mean high pressure ridge position in the Midwest. Minimal threat of showers/thunderstorms at times, with a slight chance July 14, and another risk later July 15 into July 16, based on the timing of systems in the jet stream. Temperatures in this pattern should average somewhat above normal, but not overly hot.

DAYS 11-15 (JULY 19-23)
General west to east flow with mean high pressure ridge position in the Upper Plains. Slightly greater risk of passing showers/thunderstorms at times with disturbances being able to gather a bit more energy and moisture with a slight trough in the Northeast. Temperatures in the pattern are variable, but not too far from normal overall.

7:25AM

DAYS 1-5 (JULY 8-12)
A disturbance passing south of New England will toss some of its clouds across the sky in southern portions of the region this morning, otherwise look for sunshine dominating areas to the north and regaining dominance in southern areas this afternoon, and a regionwide sunny day Tuesday, and sort-of the same Wednesday, the difference being we’ll likely see a hazier looking sky due to high altitude smoke from Canada by Wednesday. A very slow build to warmth will lead to it feeling a little hotter by Wednesday, but humidity will be reasonably low. By Thursday, however, the combo will be back – not high heat, but warm to hot enough along with increased humidity, but as a cold front heads this way from the west we’ll also introduce the chance of showers and thunderstorms later Thursday and Thursday night. Right now it looks like this front will move right along and be exiting on Friday, but a chillier pool of air aloft could still trigger a few showers, so will hold those in the forecast for now, but overall Friday does not look like a bad day. Overall, this 5-day stretch is going to hold some great vacation weather.
Forecast details…
TODAY: Some clouds across southeastern MA, eastern CT, and RI this morning, otherwise sunshine. Highs 78-85, coolest along the coast. Wind light variable with sea breezes.
TONIGHT: Clear. Lows 55-62. Wind light variable.
TUESDAY: Sunny. Highs 81-88. Wind W up to 10 MPH but still some light coastal sea breezes.
TUESDAY NIGHT: Clear but smoke arriving aloft. Lows 58-65. Wind light W.
WEDNESDAY: Smoke-filtered sunshine. Highs 85-92, except cooler Cape Cod. Wind W 5-15 MPH.
WEDNESDAY NIGHT: Partly cloudy. More humid. Lows 66-73. Wind SW 5-15 MPH.
THURSDAY: Partly sunny. Late-day showers/thunderstorms possible. Humid. Highs 86-91, cooler South Coast. Wind SW 10-20 MPH.
THURSDAY NIGHT: Mostly cloudy. Showers/thunderstorms likely. Humid. Lows 67-74. Wind SW 5-15 MPH, higher gusts.
FRIDAY: Mostly cloudy with a risk of showers early. Partly sunny with a pop up shower or thunderstorm possible thereafter. Less humid. Highs 78-85. Wind W 10-20 MPH.

DAYS 6-10 (JULY 13-17)
A general west to east flow with mean high pressure ridge position oscillating between Plains and Midwest. This pattern sends disturbances through the Northeast with brief shower/t-storm threats and otherwise generally dry but seasonably warm weather overall. Risk of passing showers/storms exists July 14, and later July 15 into July 16. We may have to watch tropical moisture to the south early next week but for now thinking that will not impact the region.

DAYS 11-15 (JULY 18-22)
The same general pattern is expected to continue with seasonably warm to briefly hot weather and a couple opportunities for showers/thunderstorms.

7:27AM

DAYS 1-5 (JULY 7-11)
A new airmass is here, drying out and cooler today, though that long-talked-about South Coast shower threat is panning out in an isolated way to start the day off as one travels from CT to RI before moving offshore, otherwise we have 4 dry days coming up as high pressure moves and and takes control of the weather. Toward midweek you’ll notice it being a little hotter and eventually more humid, especially by Thursday, when our next threat of showers/thunderstorms arrives.
Forecast details…
TODAY: Early clouds, including a South Coast shower, then turning mostly sunny. Less humid. Highs 76-83, coolest eastern coastal areas and Cape Cod. Wind N to NE 5-15 MPH with higher gusts.
TONIGHT: Clear. Lows 55-62. Wind N 5-15 MPH.
MONDAY: Sunny. Highs 77-84. Wind light variable with coastal sea breezes.
MONDAY NIGHT: Clear. Lows 56-63. Wind light variable.
TUESDAY: Sunny. Highs 82-89, cooler Cape Cod. Wind W 5-15 MPH.
TUESDAY NIGHT: Clear. Lows 58-65. Wind light W.
WEDNESDAY: Sunny. Highs 85-92, cooler Cape Cod. Wind WSW 5-15 MPH.
WEDNESDAY NIGHT: Mostly clear. More humid. Lows 65-72. Wind SW 5-15 MPH.
THURSDAY: Partly sunny. Chance of afternoon showers/thunderstorms. Humid. Highs 85-92, cooler South Coast. Wind SW 10-20 MPH.

DAYS 6-10 (JULY 12-16)
Overall west to east jet stream pattern. A trough and cold front passing by will trigger additional showers/thunderstorms on July 12. High pressure builds in with fair weather for the July 13-14 weekend. A warm front / cold front combo may bring some unsettled weather and more humidity July 15-16.

DAYS 11-15 (JULY 17-21)
No significant changes to the generally west to east flow, typical summer pattern. Shower and thunderstorm threat may return by the middle of the period after a dry start.

7:56AM

DAYS 1-5 (JULY 6-10)
Typical summertime pattern for New England. Heat and humidity today, add an approaching cold front and create a threat of thunderstorms, some of which could be strong. Will be monitoring radar through the day. Threat diminishes northwest to southeast as the front passes this evening. The front will still be close enough for early clouds and a South Coast shower threat Sunday but the trend will be to clear as we will then have an air mass much cooler and drier than the one we’re in now. High pressure brings great summer weather Monday to Wednesday, starting out pleasantly warm and dry then turning a little hotter but only slightly more humid toward midweek.
Forecast details…
TODAY: Partly sunny. Isolated to scattered thunderstorms after 3PM west and north of Boston, mostly after 5PM to the south. Humid. Highs 81-88 Cape Cod and immediate South Coast, 88-95 elsewhere. Wind SW 5-15 MPH, higher gusts.
TONIGHT: Variably cloudy. Scattered to numerous showers and thunderstorms with the threat diminishing from northwest to southeast. Any storms may be strong. Patchy fog overnight. Humid. Lows 66-73. Wind variable 5-15 MPH, higher gusts near storms, shifting to N.
SUNDAY: Mostly cloudy to partly sunny morning with a risk of a shower South Coast. Clearing midday-afternoon. Less humid. Highs 75-82. Wind N to NE 5-15 MPH with higher gusts.
SUNDAY NIGHT: Clear. Lows 55-62. Wind N 5-15 MPH.
MONDAY: Sunny. Highs 77-84. Wind light variable with coastal sea breezes.
MONDAY NIGHT: Clear. Lows 56-63. Wind light variable.
TUESDAY: Sunny. Highs 82-89, cooler Cape Cod. Wind W 5-15 MPH.
TUESDAY NIGHT: Clear. Lows 58-65. Wind light W.
WEDNESDAY: Sunny. Highs 85-92, cooler Cape Cod. Wind WSW 5-15 MPH.

DAYS 6-10 (JULY 11-15)
Overall west to east jet stream pattern. More humid with a risk of mainly afternoon showers/thunderstorms July 11 with an approaching cold front. Less humid with a risk of afternoon showers/thunderstorms July 12 with a secondary trough moving through. High pressure likely brings fair weather for July 13-14 before an approaching warm front brings cloudiness and a risk of showers back to the region to end the period.

DAYS 11-15 (JULY 16-20)
No significant changes to the generally west to east flow, typical summer pattern. Shower and thunderstorm threats early and again later in the period with otherwise mainly dry weather.

7:28AM

DAYS 1-5 (JULY 5-9)
No changes to forecast and a very quick update today. Some heat and humidity today and Saturday, with the shower/thunderstorm threat confined to isolated activity Saturday afternoon and scattered activity Saturday evening as a weak cold front crosses the region, so keep a close eye on the weather if you have outdoor plans Saturday. The front settles to the south but may be close enough to allow a few showers to skirt the South Coast for a time, before high pressure builds in for a pleasant start to next week, dry/mild Monday then quickly warming up Tuesday.
Forecast details…
TODAY: Partly cloudy. Humid. Highs 81-88 coast, 88-95 interior. Wind SW up to 10 MPH but some light coastal sea breezes possible.
TONIGHT: Partly cloudy. Humid. Lows 66-73. Wind SW 5-15 MPH.
SATURDAY: Partly cloudy. Isolated afternoon thunderstorms. Humid. Highs 88-95, cooler Cape Cod. Wind SW 5-15 MPH.
SATURDAY NIGHT: Variably cloudy. Scattered to isolated showers and thunderstorms. Humid. Lows 66-73. Wind variable 5-15 MPH.
SUNDAY: Variably cloudy. Risk of a shower near the South Coast. Less humid. Highs 77-84. Wind light N.
SUNDAY NIGHT: Partly cloudy. Lows 55-62. Wind N 5-15 MPH.

DAYS 1-5 (JULY 4-8)
Happy Birthday USA! A typical July summertime pattern will be in place throughout the period, dominated by zonal (west to east) flow of a weak jet stream. A southwesterly surface flow will bring summertime heat and humidity (not extreme) into the region today and Friday, and it will become more humid Saturday ahead of a cold front which will move across the region Saturday night, when the greatest threat of showers and thunderstorms is, although the threat itself may not be all that great. Nevertheless with so many outdoor activities ongoing and still a lot of fireworks displays scheduled for Saturday night, we need to pay attention to that threat, as you don’t need severe storms to result in danger from wind gusts, lightning, flooding, etc. By Sunday, the front will be south of the region and we’ll have turned somewhat cooler and drier, but with some lingering cloudiness and maybe a shower near the South Coast. High pressure builds in with fair weather for Monday.
