7:28AM

DAYS 1-5…
Low pressure passing north of the region through early Wednesday drags a warm front / cold front combo through southern New England from west to east and takes through early Wednesday morning to get all of its areas of showers and thunderstorms through the region. Though no severe weather outbreak will occur, a few of the heavier cells may produce strong enough wind gusts for minor wind damage, and also some torrential rain with local flash flooding. This most widespread rainfall will come in the late morning through mid afternoon hours from west to east followed by more scattered activity after. Upper level low pressure with colder air aloft will allow for a few diurnal showers and thunderstorms to form on Wednesday though most of the day will be rain-free. High pressure brings fair weather Thursday and Friday before another front slides through with a chance of showers/thunderstorms on Saturday.
TODAY: Cloudy. Numerous showers and a chance of thunderstorms developing from west to east by late morning, then becoming more scattered from west to east by later in the day. Humid. Highs 68-76, coolest immediate coast. Wind SE to S 10-15 MPH gusting above 20 MPH.
TONIGHT: Mostly cloudy. Episodes of showers and thunderstorms. Humid. Lows in the 60s. Wind SW 5-15 MPH with higher gusts.
WEDNESDAY: Variably cloudy. Lingering showers/thunderstorms Cape Cod early. Isolated showers/thunderstorms possible anywhere in the afternoon. Highs 77-84. Wind W 5-15 MPH.
THURSDAY: Mostly sunny. Lows 56-63. Highs 75-82.
FRIDAY: Partly cloudy. Lows 56-63. Highs 78-85.
SATURDAY: Partly sunny. Chance of showers/thunderstorms. Lows 60-67. Highs 80-87.

DAYS 6-10 (AUGUST 16-20)…
A couple episodes of showers and thunderstorms possible during this period but much of it will be rain-free with more humidity and near to above normal temperatures.

DAYS 11-15 (AUGUST 21-25)…
High pressure ridge becomes more established with late August heat and humidity possible and limited rain chances.

7:29AM

DAYS 1-5…
High pressure slips off to the east today. Low pressure moves through from west to east on Tuesday with unsettled weather. This low pulls away Wednesday but an upper low may still kick off a few showers. High pressure moves in with fair weather later in the week.
TODAY: Partly cloudy. Highs 71-76 coast, 77-82 interior. Wind light SE.
TONIGHT: Increasing clouds. Lows in the 60s. Wind light S.

DAYS 11-15 (AUGUST 19-23)…
Weak trough Great Lakes, high pressure offshore expands westward but not too amplified. Episodes of showers/thunderstorms to start, then becoming less numerous. Temperatures near to above normal.

7:55AM

DAYS 1-5…
This weekend will be a good example of how the ocean can modify the conditions here in southeastern New England, as a persistent northeasterly flow between high pressure to the north and low pressure to the south and east of the region will keep the air on the cooler side of average. Despite it being a little cooler than one might expect for early August, the weather will be nice, with just some clouds at times. This may include a couple bouts of low clouds from the ocean, especially Sunday. During the Monday-Wednesday period, a low pressure system will move through from west to east in sluggish fashion, first bringing a warm front toward the region Monday with increasing clouds and eventually a shower risk late, then a cold front that will take its time slogging eastward on Tuesday with lots of clouds as well as a good chance of showers and thunderstorms. Finally by Wednesday, it pushes off to the east and drier air arrives, but it may be unstable enough for a shower or thunderstorm to pop up in a few locations.
TODAY: Mostly sunny. Highs 70-75 coast, 76-81 interior. Wind NE 5-15 MPH.
TONIGHT: Partly cloudy. Lows 55-62. Wind light NE.
SUNDAY: Partly sunny. Highs 68-73 coast, 74-79 interior. Wind NE 5-15 mph.

WEDNESDAY: Partly cloudy. Isolated showers/thunderstorms possible. Lows in the 60s. Highs 75-85.

DAYS 6-10 (AUGUST 13-17)…
Fair August 13. Weak system brings shower risk later August 14 to early August 15. Another system arrives at the end of the period with a risk of showery weather. Temperatures below to near normal.

DAYS 11-15 (AUGUST 18-22)…
Will be watching for less troughing reaching the Northeast and staying back in the Great Lakes as a ridge of high pressure tries to expand westward from the Atlantic toward East Coast. Episodes of showers/thunderstorms to start, then becoming less numerous. Temperatures near to above normal.

7:30AM

DAYS 1-5…
No changes. Low pressure stays offshore from south to east of New England today through Sunday as high pressure builds to the north. This sets up a northeast to east wind which will keep it on the cool side of average across the region. Look for fair weather as rain stays generally well offshore with the low. However, by later in the weekend we may have to deal with some low cloudiness from the ocean especially near the eastern coastal areas of NH and MA. A warm front arrives Monday and brings clouds, humidity, and a chance of showers back. A slow-moving cold front traverses the region Tuesday with lots of clouds, humidity, and a good chance of showers and thunderstorms.
TODAY: Mostly sunny. Highs 70s coast, lower 80s well inland. Wind N shifting to E up to 15 MPH.
TONIGHT: Partly cloudy. Lows 55-60 interior, lower 60s coast. Wind light E to NE.
SATURDAY: Mostly sunny. Highs in the 70s, coolest coast. Wind NE 5-15 MPH.
SATURDAY NIGHT: Partly cloudy. Lows 55-60 interior, lower 60s coast. Wind light NE.
SUNDAY: Partly sunny. Highs in the 70s, coolest coast. Wind NE 5-15 MPH.
MONDAY: Mostly cloudy. Chance of showers. More humid. Lows in the 60s. Highs in the 70s.
TUESDAY: Variably cloudy. Chance of showers/thunderstorms. Humid. Lows in the 60s. Highs in the 80s.

DAYS 6-10 (AUGUST 12-16)…
Lingering showers early August 12 then fair weather returns through August 13. Another risk of showers later August 14 to early August 15 followed by fair weather again. Temperatures variable but not far from average.

DAYS 11-15 (AUGUST 17-21)…
Episodes of scattered showers/thunderstorms especially mid to late period. Temperatures near normal.

7:29AM

DAYS 1-5…
High pressure dominates today which will be a very nice Summer Day, one of many we’ve had this Summer. High pressure readjusts north of New England Friday through Monday as low pressure passes south then turns northward to the east of southern New England. Though some light rain from this system may get close, it should remain offshore, with the most influence from this combination of systems being a cooler wind from the Atlantic and some cloudiness at times.
TODAY: Mostly sunny to partly cloudy. Highs 78-85. Wind NW to N 5-15 MPH.
TONIGHT: Partly cloudy. Lows 56-63. Wind light N shifting to E.
FRIDAY: Partly sunny. Highs 72-80. Wind E 5-15 MPH.
SATURDAY AND SUNDAY: Variably cloudy. Lows 55-63. Highs 73-81.
MONDAY: Partly sunny. Lows 57-65. Highs 75-83.

DAYS 6-10 (AUGUST 11-15)…
Humidity returns with a chance of showers/thunderstorms by later August 11 through early August 12. Another around of showers/storms possible around August 13-14. Temperatures below to near normal.

DAYS 11-15 (AUGUST 16-20)…
Temperatures near seasonal averages much of the time with episodes of scattered showers and thunderstorms.

7:28AM

DAYS 1-5…
A broad trough of low pressure over the Northeast will persist for the period, preventing further heat. Its cool pool of air will help to trigger some scattered showers and thunderstorms during this afternoon, a few of which may produce hail, though a repeat of Tuesday’s severe weather is not likely. High pressure builds in with fair weather Thursday. Low pressure passes south of the region Friday and early in the weekend. It may be close enough to bring a touch of rain to the South Coast during Friday, then far enough offshore for a dry weekend with cooler than average temperatures each of the days.
TODAY: Partly cloudy. Scattered showers and a chance of thunderstorms in the afternoon. Highs 78-85. Wind W 5-15 MPH with higher gusts.
TONIGHT: Partly cloudy. Possible lingering showers early. Lows 55-62. Wind light NW.
THURSDAY: Mostly sunny. Highs 76-83. Wind light NW to N with coastal sea breezes.
FRIDAY: Mostly cloudy. Chance of rain South Coast. Lows 56-63. Highs in the 70s.
SATURDAY: Partly sunny. Lows 55-62. Highs 70-78, coolest coast.
SUNDAY: Mostly sunny. Lows 57-64. Highs 73-81, coolest coast.

DAYS 6-10 (AUGUST 10-14)…
Showers possible August 10 and again later in the period. Temperatures near to below normal.

DAYS 11-15 (AUGUST 15-19)…
Episodes of scattered showers/thunderstorms especially mid to late period. Temperatures near normal.

7:31AM

DAYS 1-5…
Strong disturbance in the area today along with a surface trough approaching from the northwest yields showers and thunderstorms. Some of the storms will be strong to severe. Quiets down but slight risk of showers with one more disturbance Wednesday. Still watching low pressure for late week.
TODAY: Variably cloudy. Episodes of showers and thunderstorms, some heavy. Locally severe storms with damaging wind and hail possible. Humid. Highs in the 80s. Wind W 5-15 MPH, but variable to strong and gusty near some storms.
TONIGHT: Partly cloudy. Chance of showers and thunderstorms early. Lows 60-68. Wind W 5-15 MPH.
WEDNESDAY: Partly cloudy. Slight risk of passing showers. Less humid. Highs 78-86. Wind NW 5-15 MPH.
THURSDAY: Increasing clouds. Chance of rain late, especially South Coast. Lows 58-66. Highs 74-82.
FRIDAY: Mostly cloudy. Chance of rain, especially South Coast. Lows 58-66. Highs 72-80.
SATURDAY: Mostly cloudy. Chance of rain early. Lows 55-64. Highs 68-76.

DAYS 6-10 (AUGUST 9-13)…
Temperatures below to near normal with mainly dry weather early in the period and a greater risk for showers later in the period.

DAYS 11-15 (AUGUST 14-18)…
Temperatures near normal with a risk of showers and thunderstorms early in the period, then drier and warmer later in the period.

7:29AM

DAYS 1-5…
Sun, heat, and more humidity dominates today ahead of a cold front, though some clouds will pop up during the day today. Showers/thunderstorms accompanying the passage of the first cold front Monday night and early Tuesday but will likely be coming through the area in weakening or dying form, so coverage may not be widespread and storms will not be a strong as they will be further to the west and north of southeastern New England. A second front later Tuesday may set off additional showers and thunderstorms in some areas. Behind the second front will be drier air by Wednesday with slight cooling. Still looking for further cooling Thursday and Friday and at least more cloudiness as low pressure passes south of the region. It remains unclear how far north an area of wet weather comes later Thursday into Friday.
TODAY: Mostly sunny to partly cloudy and hazy. More humid. Highs 82-90. Wind SW 10-20 MPH.
TONIGHT: Partly to mostly cloudy. Showers and thunderstorms possible, mainly after 10PM. Muggy. Lows 64-72. Wind SW 5-15 MPH.
TUESDAY: Variably cloudy. Chance of showers early. Scattered showers/thunderstorms mid afternoon on. Highs 82-90. Wind W 5-15 MPH and gusty.
TUESDAY NIGHT: Partly cloudy. Chance of showers and thunderstorms early. Lows 60-68. Wind W 5-15 MPH.
WEDNESDAY: Partly cloudy. Less humid. Highs 78-86. Wind NW 5-15 MPH.
THURSDAY: Increasing clouds. Chance of rain late, especially South Coast. Lows 58-66. Highs 74-82.
FRIDAY: Mostly cloudy. Chance of rain, especially South Coast. Lows 58-66. Highs 72-80.

DAYS 6-10 (AUGUST 8-12)…
Temperatures below to near normal but looking like less rain risk and more likely dry for most of the period.

DAYS 11-15 (AUGUST 13-17)…
Temperatures near normal with a risk of showers and thunderstorms early in the period, then drier and warmer later in the period.

8:26AM

DAYS 1-5…
Humidity slowly returns through Monday ahead of a cold front, but high pressure still firmly in control for today with plenty of sun before a few more clouds arrive and pop up during Monday. Showers/thunderstorms accompanying the passage of the first cold front Monday night and early Tuesday, but a second front later Tuesday may set off additional showers and thunderstorms in some areas. Behind the second front will be drier air by Wednesday with slight cooling. The cooling trend will continue Thursday but the dry weather may yield to an area of rain from the south as low pressure passes. The Thursday portion of the forecast is low confidence at this time since I’m not sure how close that system will get at this point.
TODAY: Sunny. Highs 80-88. Wind W to SW 10-20 MPH.
TONIGHT: Clear. Lows 60-68. Wind SW 5-15 MPH.
MONDAY: Partly cloudy and hazy. More humid. Highs 82-90. Wind SW 10-20 MPH.
MONDAY NIGHT: Mostly cloudy. Chance of showers and thunderstorms early. Showers likely and a chance of thunderstorms overnight. Muggy. Lows 64-72. Wind SW 5-15 MPH.
TUESDAY: Variably cloudy. Chance of showers early. Scattered showers/thunderstorms mid afternoon on. Highs 82-90. Wind W 5-15 MPH and gusty.
TUESDAY NIGHT: Partly cloudy. Chance of showers and thunderstorms early. Lows 60-68. Wind W 5-15 MPH.
WEDNESDAY: Partly cloudy. Less humid. Highs 78-86. Wind NW 5-15 MPH.

Temperatures below normal with a rain or shower risk August 7-9 then drier and warming up August 10-11.

DAYS 11-15 (AUGUST 12-16)…
Temperatures close to seasonal averages with a few episodes of showers/thunderstorms during the period.

7:29AM

DAYS 1-5…
A mainly dry and warm weekend with tolerable humidity for most. A passing disturbance later today may set off a few showers and thunderstorms, though any of them would be brief and passing. Heat and humidity increases Monday ahead of a cold front, and a shower and thunderstorm risk will probably occur Monday night with this cold front, allowing fair, warm, and less humid weather to return Tuesday and Wednesday.
TODAY: Sunny morning. Partly cloudy afternoon with isolated showers and thunderstorms. Highs in the 80s. Wind W 5-15 MPH gusting around 20 MPH.
TONIGHT: Partly cloudy evening. Clear overnight. Lows in the 60s. Wind W around 10 MPH.
SUNDAY: Mostly sunny. Highs in the 80s. Wind SW 5-15 MPH.
MONDAY: Partly cloudy. Chance of showers/thunderstorms at night. Lows 65-72. Highs 85-92.
TUESDAY: Mostly sunny. Lows 60-67. Highs 83-90.
WEDNESDAY: Partly sunny. Lows 58-65. Highs 78-85.

DAYS 6-10 (AUGUST 6-10)…
Below normal temperatures during this period. Watching a possible low pressure area that may pass south of the region or come close enough to bring some wet weather August 6-7. A second disturbance approaches from the northwest later in the period leading to a shower risk.

DAYS 11-15 (AUGUST 11-15)…
A gradual return to near to above normal temperatures with a few episodes of showers and thunderstorms during this period.

7:30AM

DAYS 1-5…
Heat stays, humidity drops today as a weak cold front moves offshore. A very warm weekend ahead with mainly dry and very warm weather. Only the risk of a few isolated showers or thunderstorms mainly late Saturday with a weak disturbance passing through. Warmth and a return to some humidity Monday-Tuesday. Approaching cold front brings another chance of showers and thunderstorms Tuesday – timing uncertain this far in advance.
TODAY: Mostly sunny. Highs 80-85 Islands, 86-92 elsewhere. Less humid. Wind W 5-15 MPH.
TONIGHT: Mostly clear. Lows in the 60s. Wind light W.
SATURDAY: Mostly sunny to partly cloudy. Isolated late-day showers and thunderstorms mainly well west of Boston. Highs in the 80s. Wind W 5-15 MPH.
SATURDAY NIGHT: Partly cloudy to mostly clear. Lows in the 60s. Wind light W.
SUNDAY: Mostly sunny to partly cloudy. Highs in the 80s. Wind light SW.
MONDAY: Partly cloudy. Lows 65-72. Highs 85-92.
TUESDAY: Variably cloudy. Chance of showers/thunderstorms. Lows 65-72. Highs 83-90.

DAYS 6-10 (AUGUST 5-9)…
Upper trough swings through the Northeast with temperatures near to slightly below normal early to mid morning, warming up late in the period. Mainly dry August 5-6, chance of showers about August 7-8.

DAYS 11-15 (AUGUST 10-14)…
Trending warmer with limited shower activity.

7:27AM

DAYS 1-5…
Cold front slices into a HHH air mass at the end of the day today, but that doesn’t always mean widespread big storms for everyone. There will be some potential for isolated showers and storms ahead of what will probably be a line of storms approaching from the west by late afternoon and evening, but the best support for storms sits in far western New England today, so it’s possible that weakening storms will be what we see moving eastward. There is always a risk that colliding boundaries from older storms or other local conditions could help keep some stronger storms going, so we will watch this. Front moves offshore by early Friday. It only gets slightly cooler behind this front but somewhat less humid, so some very warm Summer weather will be here for Friday through the weekend, though humidity may creep up a little bit by later in the weekend. Cannot rule out an isolated shower or t-storm over the weekend either as a weak disturbance will be in the area. Similar weather is expected for Monday.
TODAY: Hazy with morning sunshine then partly sunny. Isolated showers and thunderstorms possible by mid to late afternoon then a shower or thunderstorm is more likely by early evening from west to east. Humid. Highs 88-95, cooler South Coast. Wind SW 10-20 MPH. Variable and gusty winds possible with storms.
TONIGHT: Variably cloudy with a risk of showers and thunderstorms early, then becoming partly cloudy. Lowering humidity late. Lows 65-72. Wind W 5-15 MPH.
FRIDAY: Mostly sunny. Highs 85-92. Wind W 5-15 MPH.
SATURDAY THROUGH MONDAY: Partly cloudy. Daily risk of isolated showers/thunderstorms but mostly rain-free. Lows 63-70. Highs 83-90.

DAYS 6-10 (AUGUST 4-8)…
Showers/thunderstorms August 4. Fair August 5-6. Showers/thunderstorms possible August 7-8. Temperatures near to above normal.

DAYS 11-15 (AUGUST 9-13)…
Temperatures near to above normal. Rainfall near normal but variable during the period.

7:36AM

DAYS 1-5…
No changes to previous discussion regarding today into the weekend. To summarize, the heat is on today and Thursday. The chance of any thunderstorms is so minimal today and I don’t think it will happen in the forecast area so it won’t appear in the forecast. Thursday, on the other hand, the chance increases later in the day and especially evening as a cold front approaches. I’m still not convinced everybody gets hit tomorrow. It will depend on timing, development, orientation, and movement of cluster or line storms. More on that later. Quite muggy the next 2 days, less humidity Friday and Saturday before it creeps back in Sunday but with mainly dry weather Friday through the weekend other than a risk of an isolated storm in a few locations on the weekend, especially Sunday.
TODAY: Hazy sunshine. Humid. Highs 88-95. Wind SW 5-15 MPH.
TONIGHT: Mostly clear and hazy. Muggy. Lows 68-75. Wind light SW.
THURSDAY: Partly cloudy and hazy. Chance of late day and nighttime t-storms. Humid. Lows 68-75. Highs 88-95.
FRIDAY: Mostly sunny. Less humid. Lows 65-72. Highs 85-92.
SATURDAY: Mostly sunny. Lows 63-70. Highs 86-93.
SUNDAY: Partly cloudy. More humid. Risk of isolated thunderstorms. Lows 65-72. Highs 87-94.

DAYS 6-10 (AUGUST 3-7)…
Warm and humid with a daily risk of showers and thunderstorms August 3-5. Dry, warm, less humid by August 6. Humidity returns at the end of the period with a risk of showers.

DAYS 11-15 (AUGUST 8-12)…
Ridges of high pressure in the central US and off the East Coast with a very weak trough between them will be the dominant pattern. Near normal rainfall and near to above normal temperatures result.

7:26AM

DAYS 1-5…
The old frontal boundary is just about gone, but today’s kicker for potential thunderstorms will be a disturbance or trough moving through from north to south during the afternoon and a couple of convergence zones between weak sea breezes and weak land breezes. The most likely chance to see activity today will be within 30 miles of the coast of NH and the eastern coast of MA. A few initial storms may fire up along a boundary in southeastern MA as early as noon or 1PM, but it’s unclear if storms will be able to form here because of a layer of warm/dry air at mid levels of the atmosphere. Eventually that layer should move away. Whether those initial storms form or not, another area of showers/thunderstorms should get going in southeastern NH and/or northeastern MA and redevelop their way south and southeast along the coastal plain of MA during the course of the afternoon. Because of the variability of convection, some storms may be strong to even marginally severe in some areas and barely impact others, so it will be important to follow the trends during the day. By tonight, all activity diminishes. Wednesday, a stronger layer of warm air above will probably impede any storm development, but by Thursday, an approaching cold front will bring a much better chance of showers/thunderstorms, possibly in squall line form, by later in the day or sometime at night, depending on timing. Some areas will see a heatwave today through Thursday, but Boston likely will not, as I don’t think they will make 90 due to the earlier onset of a sea breeze there. Friday/Saturday will both be very warm to hot days but with lower humidity than the next 3 days have.
TODAY: Partly sunny and hazy. Scattered showers and thunderstorms mainly in southeastern NH and eastern MA midday and afternoon. Humid. Highs 78-85 coast, 85-92 interior. Wind light SW to W except coastal sea breezes developing.
TONIGHT: Partly cloudy and hazy. Muggy. Lows 66-73. Wind light SW.
WEDNESDAY: Hazy sunshine. Humid. Highs 88-95. Wind SW 5-15 MPH.
THURSDAY: Partly cloudy and hazy. Chance of late day and nighttime t-storms. Humid. Lows 68-75. Highs 88-95.
FRIDAY: Mostly sunny. Less humid. Lows 65-72. Highs 85-92.
SATURDAY: Mostly sunny. Lows 63-70. Highs 86-93.

DAYS 6-10 (AUGUST 2-6)…
Hot and humid with isolated thunderstorms August 2. Warm and humid with a daily risk of showers and thunderstorms August 3-5. Dry, warm, less humid by August 6.

DAYS 11-15 (AUGUST 7-11)…
Ridges of high pressure in the central US and off the East Coast with a very weak trough between. This pattern is typically warm and humid here with a few episodes of showers and thunderstorms.
