DAYS 1-5 (AUGUST 9-13)
No big changes on this update. Humidity hangs around today as a cold front slowly moves through the region, so after the damp start with some lingering showers behind last evening’s showers/storms, there may be some additional showers and storms developing again during today, though more scattered to isolated than the activity ended up being yesterday. The pick of the week, weatherwise, will be Friday – a very warm day with somewhat lower humidity. The weekend will be less warm, but more humid, thanks to a low pressure circulation south of New England and a general southeasterly to easterly air flow. As the low start to move to the west the flow may turn more southerly by Monday, still a humid set-up with a shower threat. Forecast details…
TODAY: Mostly cloudy with numerous to scattered showers morning. Partly cloudy with scattered to isolated showers and thunderstorms afternoon. Humid. Highs 77-84. Wind SW to W 5-15 MPH.
TONIGHT: Mostly clear. Less humid. Lows 62-68. Wind light W.
FRIDAY: Mostly sunny. Highs 77-82 Cape Cod, 83-88 elsewhere. Wind W 5-15 MPH.
SATURDAY: Partly sunny. More humid. Possible showers favoring the South Coast. Lows in the 60s. Highs from the middle 70s to lower 80s.
SUNDAY: Mostly cloudy. Showers possible. Humid. Lows in the 60s. Highs from the middle 70s to lower 80s.
MONDAY: Mostly cloudy. Showers and thunderstorms possible. Humid. Lows in the 60s. Highs from the middle 70s to middle 80s.

DAYS 6-10 (AUGUST 14-18)
Additional showers and possible thunderstorms with most south to southwest air flow August 14 followed by a more westerly air flow with a drier and warmer to hotter trend again.

DAYS 11-15 (AUGUST 19-23)
A disturbance from the west cuts into the ridge with a shower/thunderstorm threat and a quick shot of cooler air before warmth and humidity resumes control.

7:13AM

DAYS 1-5 (AUGUST 8-12)
The Dog Days have been in full force and we get one more today, but then a little break is coming up, more from the heat than the humidity, however we are going to feel somewhat of a break in the humidity as well for a short period of time during the end of this week. First, 3 players will be the trigger for possible showers and thunderstorms. The first will be a sea breeze boundary that forms today along both eastern and southern coasts of southern New England which can trigger isolated to scattered showers/storms any time from early afternoon to early evening. The second will be a trough approaching from the west that will have already fired off showers/storms in more of a line or line clusters to the west of the region. This will bring the risk of isolated to scattered showers/storms in from west to east later this evening and into the morning hours of Thursday. The third is a cold front which will be crossing the region during the course of the day Thursday and this will extend the showers and storm threat, although coverage is expected to drop off from west to east during the day. Beyond this conglomeration of firing mechanisms, we get a sliver of warm but drier air for Friday. The position of high pressure, and a bit of a low pressure circulation developing to the south, is going to result in an air flow from the east or southeast during the coming weekend, resulting in a more significant break from any heat. The moisture associated with the low pressure circulation should stay far enough south to allow a rain-free Saturday, but the threat of some wet weather increases by Sunday as this area creeps a bit to the north. We’ll also notice the humidity making a comeback during the course of the weekend, especially by Sunday, even without the heat. Forecast details…
TODAY: Hazy sun dominant early then clouds popping up leading to a variably cloudy sky with isolated to scattered showers and thunderstorms this afternoon. Humid. Highs 78-85 coast, 85-92 interior. Wind light variable with coastal sea breezes.
TONIGHT: Variably cloudy. Isolated to scattered showers and thunderstorms, favoring late evening and overnight. Humid. Lows 65-73. Wind light SE shifting to SW.
THURSDAY: Mostly cloudy with numerous to scattered showers and thunderstorms morning. Partly cloudy with scattered to isolated showers and thunderstorms afternoon. Humid. Highs 77-84. Wind SW to W 5-15 MPH.
THURSDAY NIGHT: Mostly clear. Less humid. Lows 62-68. Wind light W.
FRIDAY: Mostly sunny. Highs 77-82 Cape Cod, 83-88 elsewhere. Wind W 5-15 MPH.
SATURDAY: Partly sunny. Lows in the 60s. Highs from the middle 70s to lower 80s.
SUNDAY: Mostly cloudy. Showers possible. More humid. Lows in the 60s. Highs from the middle 70s to lower 80s.

DAYS 6-10 (AUGUST 13-17)
A low pressure circulation to the south combines with trough moving eastward in the jet stream, allowed by a weakening and shifting eastward of the Atlantic high pressure ridge, bringing additional showers and thunderstorms during the August 13-14 period. A more westerly flow with drier weather follows this and with a little more strength to the ridge off the coast it pushes the jet stream north again and allows a trend to hotter weather after a cooler start to the period.

DAYS 11-15 (AUGUST 18-22)
The ridge holds on early in the period then gives way briefly to a passing trough, a shower/thunderstorm threat, and a quick shot of cooler air, before a quick return to warmth and humidity later in the period.

7:24AM

DAYS 1-5 (AUGUST 7-11)
Very quick update because 1) there are no changes (again) and 2) I spent too much time in the comment section. Another hot one today as the ridge sits atop the area. Then the long-talked-about eastward slip of the ridge takes place starting later today and onward through late this week, allowing the trough to the west to approach and a front to slowly cross the region. Our opportunity for showers/storms, isolated at first, arrives late today from west to east, and they will be of the scattered variety Wednesday only to become more isolated again during Thursday as we enter the final hours of the window of chance. Another opportunity may present itself in isolated form by later Saturday as another front gets close. “Cold fronts” in this pattern are not going to deliver refreshing dry air, as they are usually at the end of their life cycle and in the process of washing out. So without further ado, here is a detailed forecast very much the same looking as the one before it…
TODAY: Partly cloudy. Isolated thunderstorms mid afternoon on favoring areas well west of Boston. Humid. Highs 82-87 coast, 87-92 interior. Wind SW 5-15 MPH.
TONIGHT: Mostly cloudy. Isolated showers and thunderstorms. Humid. Lows 66-74. Wind light SW.
WEDNESDAY: Variably cloudy. Humid. Scattered showers/thunderstorms. Highs 82-90. Wind SW 5-15 MPH.
WEDNESDAY NIGHT: Variably cloudy. Humid. Scattered showers/thunderstorms. Lows 65-73. Wind light S to SW.
THURSDAY: Partly sunny. Slightly less humid. Isolated showers and thunderstorms through mid afternoon. Highs 80-87. Wind W up to 10 MPH.
FRIDAY: Mostly sunny. Lows in the 60s. Highs in the 80s.
SATURDAY: Partly cloudy. Isolated showers or thunderstorms possible. Lows in the 60s. Highs in the 80s.

DAYS 6-10 (AUGUST 12-16)
Isolated thunderstorms are possible August 12 and 14, otherwise mainly dry weather and temperatures ending up above normal with more building heat as the dominant high pressure ridge slides back to the west, closer to the Atlantic Coast.

DAYS 11-15 (AUGUST 17-21)
Very warm to hot pattern with mainly isolated showers/thunderstorms at times as the Bermuda High remains dominant but some heat from the middle of the US also gets transported via the Midwest and Great Lakes ahead of another advancing trough through this first half of this period. By late in the period this trough may send a more general area of showers/storms through followed by a brief shot of cooler air.

6:53AM

DAYS 1-5 (AUGUST 6-10)
High pressure ridge dominates and heat peaks today, then the ridge slips back to the east a little and allows a trough from the west to get closer. This will create an approximately 48 hour long period in which showers and thunderstorms are possible from about the middle of Tuesday afternoon to the middle of Thursday afternoon, but the most likely time to see these will be Wednesday. This chance diminishes late in the week as the piece of the trough that comes eastward lifts out and high pressure regains control. Forecast details…
TODAY: Mostly sunny. Moderately humid. Highs 80-88 south-facing shores, 89-96 elsewhere. Wind SW 5-15 MPH.
TONIGHT: Mostly clear. Lows 65-73. Wind light SW.
TUESDAY: Partly cloudy. Isolated thunderstorms mid afternoon on. Humid. Highs 82-87 coast, 87-92 interior. Wind SW 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Scattered showers. Isolated thunderstorms. Humid. Lows 66-74. Wind light SW.
WEDNESDAY: Variably cloudy. Humid. Showers/thunderstorms likely. Highs 82-90. Wind SW 5-15 MPH.
THURSDAY: Partly sunny. Slightly less humid. Isolated showers and thunderstorms through mid afternoon. Lows from the lower 60s to lower 70s, warmest in urban areas. Highs in the 80s.
FRIDAY: Mostly sunny. Lows in the 60s. Highs in the 80s.

DAYS 6-10 (AUGUST 11-15)
Isolated thunderstorms are possible August 12 and 14, otherwise mainly dry weather and temperatures ending up above normal with more building heat as the dominant high pressure ridge slides back to the west, closer to the Atlantic Coast.

DAYS 11-15 (AUGUST 16-20)
Very warm to hot pattern with mainly isolated showers/thunderstorms at times as the Bermuda High remains dominant but some heat from the middle of the US also gets transported via the Midwest and Great Lakes ahead of another advancing trough.

8:18AM

DAYS 1-5 (AUGUST 5-9)
Short and sweet update, with basically no changes from yesterday’s forecast. More heat for a few days as ridge dominates and then that ridge slides to the east again and a trough brings in a better shower/storm risk by the middle of next week. Forecast details…
TODAY: Mostly sunny. Moderately humid. Highs 78-85 Cape Cod, 85-92 elsewhere. Wind W 5-15 MPH.
TONIGHT: Mostly clear. Lows 64-72. Wind light W.
MONDAY: Mostly sunny. Moderately humid. Highs 80-88 south-facing shores, 89-96 elsewhere. Wind SW 5-15 MPH.

THURSDAY: Partly sunny. Slightly less humid. Isolated showers and thunderstorms. Lows from the lower 60s to lower 70s, warmest in urban areas. Highs in the 80s.

DAYS 6-10 (AUGUST 10-14)
Isolated thunderstorms are possible August 11, 12, and 14, otherwise mainly dry weather and temperatures ending up above normal with more building heat as the dominant high pressure ridge slides back to the west, closer to the Atlantic Coast.

DAYS 11-15 (AUGUST 15-19)
Very warm to hot pattern with mainly isolated showers/thunderstorms at times as the Bermuda High remains dominant but some heat from the middle of the US also gets transported eastward as well.

12:51PM

COMMENTARY
Apology for the late regular update. Got caught up in following the band of rain/thunderstorms that included a couple tornado warnings. Significant damage occurred in Webster MA but it is unclear yet whether this was caused by a tornado, microburst, or straight-line winds. The NWS will investigate and issue a report on it. The area was under a tornado warning at the time but that is no guarantee that a tornado actually touched down. It was occurring in an area of heavy rain and very poor visibility so there was likely no human sighting of an actual tornado on the ground. The NWS will investigate the damage.

DAYS 1-5 (AUGUST 4-8)
The “fun” of the morning is generally over with but the band of rain and some downpours continues to press eastward through eastern MA and southeastern NH and there are still some areas of flooding being reported. As this area moves away today the atmosphere remains unstable, and with a front still yet to come through, other showers and storms will form, and though they may not be as widespread as this morning’s activity, some of them can be rather strong. This threat goes on until around sunset before things settle down tonight, and then high pressure moves in and it’s all about the feel of summer. Although the humidity will drop a little bit for Sunday and Monday, you won’t feel much of a difference as it will heat up. Humidity comes back up Tuesday as the heat continues, and then when we get to Wednesday we may be looking at some interesting weather as showers/storms appear likely as a front moves into the hot and humid air mass. Forecast details…
THIS AFTERNOON: Mostly cloudy. Rain and possible thunder east coastal MA and NH through Cape Cod gradually diminishing but scattered to numerous showers and thunderstorms are possible anywhere else and can develop rather quickly. Very humid. Highs 75-83. Wind S 5-15 MPH, gusty at times, also becoming variable at times.
TONIGHT: Variably cloudy with a lingering shower possible early. Clearing but with patchy fog overnight. Humid. Lows 63-70. Wind light variable becoming W up to 10 MPH.
SUNDAY: Mostly sunny. Moderately humid. Highs 78-85 Cape Cod, 85-92 elsewhere. Wind W 5-15 MPH.
SUNDAY NIGHT: Mostly clear. Lows 62-70. Wind light W.
MONDAY: Mostly sunny. Moderately humid. Highs 80-88 south-facing shores, 89-96 elsewhere. Wind SW 5-15 MPH.
TUESDAY: Partly cloudy. More humid. Lows from the middle 60s to middle 70s, warmest in urban areas. Highs from the lower 80s to lower 90s, coolest south-facing shores.
WEDNESDAY: Variably cloudy. Humid. Showers/thunderstorms likely. Lows from the middle 60s to middle 70s, warmest in urban areas. Highs in the 80s.

DAYS 6-10 (AUGUST 9-13)
Isolated thunderstorms are possible August 9, 11, and 12, otherwise mainly dry weather and temperatures ending up above normal with more building heat as the dominant high pressure ridge, which briefly lets go of the area, makes a comeback mid to late period.

DAYS 11-15 (AUGUST 14-18)
Very warm to hot pattern with mainly isolated showers/thunderstorms at times as the Bermuda High remains dominant but some heat from the middle of the US also gets transported eastward.

9:53AM

DAYS 1-5 (AUGUST 2-6)
Again a lot of repeating here. Bermuda High, etc etc, you get it by now. Today will be like yesterday, very warm and humid, chance of passing storms later but favoring areas west and north of Boston. The axis may end up a little further northwest than it was able to get yesterday but we’ll see if this holds, because outflow boundaries from storms can “recreate” where things happen. Still expecting a front to cross the region Saturday and an additional wave of low pressure on it may make things a little more interesting in terms of where and when storms occur and how severe they may end up. More on this in the comments below and on the next update. Slightly less humid but hotter air arrives Sunday into Monday but by Tuesday the ridge slides to the east a bit and a new trough approaches from the west with a greater risk for showers/storms again. Forecast details…
TODAY: Partly cloudy. Isolated to scattered showers/thunderstorms. Humid. Highs 83-92, coolest South Coast. Wind SW 5-15 MPH.
TONIGHT: Partly cloudy. Patchy fog. Humid. Lows 67-74. Wind light SW.
SATURDAY: Variably cloudy. Showers/thunderstorms likely, favoring afternoon and evening. Humid. Highs 78-87, coolest South Coast. Wind SW 5-15 MPH.
SATURDAY NIGHT: Mostly cloudy with showers likely early, then gradual clearing but areas of fog. Humid. Lows 63-70. Wind light variable.
SUNDAY: Areas of fog early, otherwise mostly sunny. Slightly less humid. Highs 82-87 coast, 87-92 interior. Wind light variable with light sea breezes.
MONDAY: Mostly sunny. Lows from the middle 60s to lower 70s. Highs from the middle 80s to lower 90s.
TUESDAY: Partly sunny. More humid. Chance of afternoon or evening showers and thunderstorms. Lows from the middle to upper 60s. Highs in the 80s.

DAYS 6-10 (AUGUST 8-12)
Opportunities for showers and thunderstorms with warmth and high humidity as a ridge is offshore, though further east, and a trough is anchored to the west of New England. In August, this is a warm, muggy, and somewhat showery pattern.

DAYS 11-15 (AUGUST 13-17)
Atlantic ridge comes back west and mid August heat and humidity and a daily risk for isolated to scattered showers/t-storms seems to be what we’ll experience.

7:28AM

DAYS 1-5 (AUGUST 2-6)
Bermuda High controls the weather and will be the driving force for some time, however there will be a front from the west that does make it through the region during the weekend. After 2 days of air mass type isolated to scattered showers and thunderstorms through Friday, activity may increase with this front Saturday and then some drier, but hotter air will be here for Sunday and Monday. Forecast details…
TODAY: Partly cloudy. Isolated to scattered showers/thunderstorms. Humid. Highs 83-92, coolest South Coast. Wind SW 5-15 MPH.
TONIGHT: Partly cloudy. Patchy fog. Humid. Lows 67-74. Wind light SW.
FRIDAY: Partly cloudy. Isolated to scattered showers/thunderstorms. Humid. Highs 83-92, coolest South Coast. Wind SW 5-15 MPH.
FRIDAY NIGHT: Partly cloudy. Patchy fog. Humid. Lows 67-74. Wind light SW.
SATURDAY: Variably cloudy. Showers/thunderstorms likely, favoring afternoon and evening. Humid. Highs 78-87, coolest South Coast. Wind SW 5-15 MPH.
SUNDAY & MONDAY: Mostly sunny. Lows from the middle 60s to lower 70s. Highs from the middle 80s to lower 90s.

DAYS 6-10 (AUGUST 7-11)
Ridge slips back to the east and allows more Midwest trough to slide into the Northeast, and while the heat eases the humidity tries to stay in place, and couple fronts interacting with it will increase the chance of showers and thunderstorms during this period.

DAYS 11-15 (AUGUST 12-16)
Our friendly Atlantic ridge comes back west, humidity generally stays, showers/storms become more isolated, and heat increases again.

8:19AM

DAYS 1-5 (AUGUST 1-5)
The muggies are returning and will be brought in full force by a passing warm front today. The passage of this front may also trigger a few showers and thunderstorms, and although the storm risk itself is not that high, any that do form have the potential to be severe, so something we’ll have to watch. The main threat window should be 2PM-6PM across the region and favor areas west and north of Boston. Thursday-Saturday it’s the classic Bermuda High setup with warm to hot weather and high humidity, and a daily risk of showers/storms, but no all-day rain, just threats that favor afternoons and evenings, but this risk will increase on Saturday as a frontal boundary is moving in. This front may take the edge of the humidity but will allow it to be a little hotter by Sunday. Forecast details…
TODAY: Partly sunny to mostly cloudy. Isolated showers late morning to early afternoon. Isolated showers and thunderstorms mid to late afternoon favoring areas west and north of Boston. Any thunderstorms can be severe, but the risk is very low in any given location. Increasingly humid. Highs 75-80 coast, 80-85 interior. Wind light S to SE, shifting to SW late.
TONIGHT: Partly cloudy. Patchy fog. Humid. Lows 66-73. Wind light SW.
THURSDAY: Partly sunny. Isolated to scattered showers/thunderstorms. Humid. Highs 83-92, coolest South Coast. Wind SW 5-15 MPH.
THURSDAY NIGHT: Partly cloudy. Patchy fog. Humid. Lows 67-74. Wind light SW.
FRIDAY: Partly sunny. Isolated to scattered showers/thunderstorms. Humid. Highs 83-92, coolest South Coast. Wind SW 5-15 MPH.
SATURDAY: Variably cloudy. Showers/thunderstorms likely, favoring afternoon and evening. Humid. Lows from the upper 60s to middle 70s. Highs in the 80s.
SUNDAY: Mostly sunny. Lows from the middle 60s to lower 70s. Highs from the middle 80s to lower 90s.

DAYS 6-10 (AUGUST 6-10)
Heat and humidity strongest early in the period then at least the heat eases a little as the ridge loses some of its grip, but this may mean more showers/thunderstorms as well.

DAYS 11-15 (AUGUST 11-15)
Ridge is a bit more to the east and trough a little closer to the region early in the period with a better shower/thunderstorm risk, then ridge comes back west yet again with additional heat and humidity middle and end of this period.

7:18AM

DAYS 1-5 (JULY 31-AUGUST 4)
Humidity’s getting ready to make a come-back, to be felt increasing slightly later today but much more noticeably during Wednesday as a warm front passes through. This front may bring a few showers and then trigger a few thunderstorms as it passes. Thursday through Saturday will be very warm and humid days with a daily risk for a few showers and storms as we’ll be in a southwesterly flow around a Bermuda High. Forecast details…
TODAY: Sun/cloud mix. Highs 78-86, coolest coast. Wind light variable with sea breezes.
TONIGHT: Mostly cloudy. Humid. Slight chance of a shower. Lows 66-72. Wind light S.
WEDNESDAY: Mostly cloudy with scattered showers morning. Partly sunny with isolated thunderstorms afternoon. Humid. Highs 82-90. Wind S to SW 5-15 MPH.
WEDNESDAY NIGHT: Partly cloudy. Patchy fog. Humid. Lows 66-73. Wind light SW.
THURSDAY: Partly sunny. Isolated to scattered showers/thunderstorms. Humid. Highs 83-92, coolest South Coast. Wind SW 5-15 MPH.
FRIDAY & SATURDAY: Partly sunny. Isolated to scattered showers/thunderstorms. Humid. Lows from the upper 60s to middle 70s. Highs from the middle 80s to lower 90s, coolest South Coast.

DAYS 6-10 (AUGUST 5-9)
Ridge dominates the East Coast again with more heat and humidity resulting but a slightly lower risk of showers and storms August 5-6 before the threat increases again as the ridge nudges eastward and the heat eases slightly mid to late period.

DAYS 11-15 (AUGUST 10-14)
Ridge is a bit more to the east and trough a little closer to the region early in the period with a better shower/thunderstorm risk, then ridge comes back west yet again with additional heat and humidity toward the end of the period.

7:11AM

DAYS 1-5 (JULY 30-AUGUST 3)
Today’s update finds no need again for major changes to the forecast. After coming down a little bit later in the weekend, the humidity remains below the oppressive category early this week as the last couple days of July go by, and then as the Bermuda High takes over again it’s back as we start August, along with the risk of showers and thunderstorms at times. Heat won’t be too high, although humidity compensates for that and makes it feel hotter anyway. Forecast details…
TODAY: Partly cloudy. Highs 78-86, coolest coast. Wind light variable with sea breezes.
TONIGHT: Partly cloudy. Lows 63-69. Wind light SW.
TUESDAY: Variably cloudy. Slight risk of a late day shower. More humid late. Highs 78-85 coast, 85-92 interior. Wind SW 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Humid. Slight chance of a shower. Lows 66-72. Wind light SW.
WEDNESDAY: Partly sunny. Isolated to scattered afternoon showers and thunderstorms. Humid. Highs 82-90, coolest South Coast. Wind SW 5-15 MPH.
THURSDAY & FRIDAY: Partly sunny. Isolated to scattered showers/thunderstorms. Humid. Lows from the middle 60s to lower 70s. Highs in the 80s to around 90.

DAYS 6-10 (AUGUST 4-8)
Ridge dominates the East Coast again with more heat and humidity resulting but a slightly lower risk of showers and storms August 4-6 before the threat increases again as the ridge nudges eastward and the heat eases slightly later in the period.

DAYS 11-15 (AUGUST 9-13)
Ridge is a bit more to the east and trough a little closer to the region early in the period with a better shower/thunderstorm risk, then ridge comes back west yet again with additional heat and humidity toward the end of the period.

11:06AM

DAYS 1-5 (JULY 29-AUGUST 2)
Quick and easy update today, WHW readers! No changes to the forecast. High pressure brings a humidity reprieve today and Monday before our friendly Atlantic ridge starts to retrograde (move westward) and return the humidity as July ends and August gets underway. The shower and thunderstorm threat that has been present recently will also take a break for a few days, with the first chance of anything returning being late Tuesday, albeit not a great chance, and then we’ll start to see the daily risk of them, though not likely widespread, by the middle of next week. And although this midweek storm risk is several days away, I have seen some early signs that the pattern may support severe storms where they occur, so something to keep in mind going forward. Forecast details…
TODAY: Filtered sunshine. Less humid. Highs 78-85, coolest coast. Wind light variable with sea breezes.
TONIGHT: Mostly clear. Lows 62-68. Wind light variable.
MONDAY: Partly cloudy. Highs 78-86, coolest coast. Wind light variable with sea breezes.
MONDAY NIGHT: Partly cloudy. Lows 63-69. Wind light SW.
TUESDAY: Partly sunny. Slight chance of late-day showers or thunderstorms. More humid. Highs 78-85 coast, 85-92 interior. Wind SW 5-15 MPH.
WEDNESDAY & THURSDAY: Partly sunny. Isolated to scattered showers/thunderstorms. Humid. Lows from the middle 60s to lower 70s. Highs in the 80s to lower 90s.

DAYS 6-10 (AUGUST 3-7)
Ridge dominates the East Coast again with more heat and humidity resulting. A daily opportunity for isolated to scattered showers and thunderstorms but much of this time will be rain-free.

DAYS 11-15 (AUGUST 8-12)
Ridge slides back east and takes the edge off the heat, but overall pattern still warm/humid, with occasional opportunities for showers/thunderstorms as the Midwest trough gets a little closer again.

9:51AM

DAYS 1-5 (JULY 28-AUGUST 1)
As the July days slip toward their conclusion and August arrives we will go through a period of “pattern readjustment”, or basically our oscillating Atlantic ridge will finish its slip to the east and then start to come back to the west, in turn pushing the Great Lakes & Midwest trough back to the west as well after having allowed it to slip eastward. This eastward displacement of the trough is what is responsible for our current unsettled weather, i.e., the shower and thunderstorm threat as a couple fronts move slowly through the region. The final front in the series is over the area now and will take the entirety of today and this evening to finally make its way offshore, so while this is ongoing we’ll have to be on the look-out for showers and thunderstorms. No, this is not going to turn into a widespread rain event or a washed-out Saturday, but if you have outdoor plans you’ll want to keep an eye on the weather, just in case you have to “get out of the way” as a shower or storm passes through. This is not the type of day to cancel outdoor plans, but we should be aware of what can happen. After this come two quiet and summery days Sunday and Monday thanks to high pressure being in control. This also comes with somewhat lower humidity than what we have seen recently. That humidity starts to make a comeback Tuesday when a shower or storm is possible, especially late, and by Wednesday of next week we’re back in the muggy pattern with a shower and thunderstorm threat. Forecast details…
TODAY: Partly cloudy. Isolated to scattered showers and thunderstorms. Any storms can contain downpours, frequent lightning, and briefly gusty wind, but should not last too long at any one location. Highs 78-84 coast, 84-90 interior. Wind W 5-15 MPH.
TONIGHT: Partly cloudy. Isolated showers and thunderstorms evening. Lows 64-70. Wind light W.
SUNDAY: Partly sunny. Less humid. Highs 78-85, coolest coast. Wind light variable with sea breezes.
SUNDAY NIGHT: Mostly clear. Lows 62-68. Wind light variable.
MONDAY: Partly cloudy. Highs 78-86, coolest coast. Wind light variable with sea breezes.
TUESDAY: Partly sunny. Chance of showers and thunderstorms late in the day. More humid. Lows in the 60s. Highs from the upper 70s to upper 80s, coolest coast.
WEDNESDAY: Partly sunny. Isolated to scattered showers/thunderstorms. Humid. Lows from the middle 60s to lower 70s. Highs in the 80s to lower 90s.

DAYS 6-10 (AUGUST 2-6)
Ridge dominates the East Coast again with more heat and humidity resulting. A daily opportunity for isolated to scattered showers and thunderstorms but much of this time will be rain-free.

DAYS 11-15 (AUGUST 7-11)
Ridge nudges back east and takes the edge off the heat, but overall pattern still warm/humid, with occasional opportunities for showers/thunderstorms.

7:23AM

DAYS 1-5 (JULY 27-31)
July’s final 5 will present a couple transitions, first from humid to less humid as a couple fronts move through the region, then back to more humid at the end of the period as we start to feel westward expansion of high pressure from the Atlantic once again, as this was the expected predominant pattern starting in late July. These transitions come with at least some shower/thunderstorm risk. Forecast details…
TODAY: Partly to mostly sunny. Highs 78-83 South Coast, 83-88 elsewhere. Wind W 5-15 MPH.
TONIGHT: Variably cloudy. Scattered showers and a slight chance of a thunderstorm west to east late. Lows 63-69. Wind SW 5-15 MPH.

MONDAY: Partly cloudy. Lows in the 60s. Highs from the upper 70s to middle 80s, coolest coast.
TUESDAY: Partly sunny. Chance of showers and thunderstorms. Lows in the 60s. Highs from the upper 70s to upper 80s, coolest coast.

DAYS 6-10 (AUGUST 1-5)
Ridge dominates the East Coast again with more heat and humidity resulting. A daily opportunity for isolated to scattered showers and thunderstorms but much of this time will be rain-free.

DAYS 11-15 (AUGUST 6-10)
Ridge nudges back east, but overall pattern still warm/humid, with occasional opportunities for showers/thunderstorms.

7:21AM

DAYS 1-5 (JULY 26-30)
2 cold fronts head through the region, one during today, another by early Saturday, and they will each take the humidity down a peg, so that by the end of the coming weekend it’s noticeably more comfortable than much of this week has been. Each of these fronts will produce a shower and thunderstorm risk.
