Sunday Forecast Update

8:07AM

DAYS 1-5…
Yesterday’s not-so-great thunderstorm forecast now behind me, time to look ahead, and so far I don’t see any changes from what was posted previously. So there is simply no need to repeat a discussion here.
TODAY: Mostly sunny. Humid. Highs 80-85 Cape Cod and immediate shorelines, 86-91 elsewhere. Wind light variable with light sea breezes.
MONDAY: Sunny. Humid. Lows 65-73. Highs 88-95.

WEDNESDAY: Partly cloudy. Humid. Lows 65-73. Highs 86-93.
THURSDAY: Partly cloudy. Humid. Isolated thunderstorms. Lows 65-73. Highs 86-93.

DAYS 6-10 (AUGUST 21-25)…
Often humid, warm to hot, and limited shower/thunderstorm chances throughout the period.

DAYS 11-15 (AUGUST 26-30)…
More of the same with above normal temperatures and near to below normal rainfall, though some threat of scattered heavier showers/thunderstorms at times.

Saturday Forecast Update

7:55AM

DAYS 1-5…
Here it comes. Classic Summer weather. This is the pattern we have suspected would be getting established at some point during the back-half of Summer. Flat ridge of high pressure will be dominant across the eastern US with occasional disturbances trying to push though as the jet streams sits not that far to the north will be the overall set-up that quickly establishes itself this weekend and remains next week. One such disturbance, represented by a weakening and dissipating cold front, may produce a few showers and thunderstorms today, with a second shot at the same type of thing Tuesday. Largely, however, the next 5 days will be rain-free, warm to hot, and on the humid side.
TODAY: Partly cloudy. Isolated showers and thunderstorms in the afternoon, favoring areas north and west of Boston during the first half of the afternoon and further to the southeast later in the day. More humid. Highs 78-83 South Coast, 84-89 elsewhere. Wind SW up to 10 MPH.
TONIGHT: Partly cloudy. Humid. Lows in the 60s. Wind light variable.
SUNDAY: Mostly sunny. Humid. Highs 80-85 Cape Cod and immediate shorelines, 86-91 elsewhere. Wind light variable with light sea breezes.
MONDAY: Sunny. Humid. Lows 65-73. Highs 88-95.
TUESDAY: Partly cloudy. Humid. Isolated thunderstorms. Lows 65-73. Highs 86-93.
WEDNESDAY: Partly cloudy. Humid. Lows 65-73. Highs 86-93.

DAYS 6-10 (AUGUST 20-24)…
Often humid, warm to hot, and limited shower/thunderstorm chances throughout the period.

DAYS 11-15 (AUGUST 25-29)…
More of the same with above normal temperatures and near to below normal rainfall, though some threat of scattered heavier showers/thunderstorms at times.

Friday Forecast Update

7:23AM

DAYS 1-5…
The Dog Days are over (they run July 3 through August 11 by definition) but the dogs are arriving late this season as we’ll be seeing some heat building into the region during the next 5 days. It doesn’t hit right away, however. First we go through a weak warm front / cold front combination later today through Saturday, moisture starved and falling apart, producing only some cloudiness later today as showers to the northwest never get close, then some additional cloudiness for Saturday with a relatively low risk of a few showers and thunderstorms. By Sunday, high pressure builds overhead then sinks to the south, allowing for the heat to build in by the start of the week. By late Tuesday, a thunderstorm threat exists as a cold front approaches from the north.
TODAY: Mostly sunny to partly cloudy. Highs 73-78 Cape Cod and immediate coast, 78-83 elsewhere. Wind light variable in the morning, light SE to S in the afternoon.
TONIGHT: Partly to mostly cloudy. Lows in the 60s. Wind light S.
SATURDAY: Variably cloudy. Slight chance of showers and thunderstorms. Highs 75-82 Cape Cod and South Coast, 80s elsewhere. Wind light SW.
SUNDAY: Mostly sunny. Lows in the 60s. Highs 84-91.
MONDAY: Mostly sunny. Lows 65-72. Highs 86-93.
TUESDAY: Partly cloudy. Isolated thunderstorms late. Lows 66-73. Highs 86-93.

DAYS 6-10 (AUGUST 19-23)…
Very warm and humid with showers/thunderstorms possible August 19. Cooler and drier August 20. Mainly dry with building heat and humidity August 21-23.

DAYS 11-15 (AUGUST 24-28)…
High pressure ridge dominates. Temperatures above normal. Rainfall below normal.

Thursday Forecast Update

7:26AM

DAYS 1-5…
No significant changes from yesterday’s post.
High pressure brings dry weather and lots of sun Thursday. An approaching warm front will increase some cloudiness during Friday but overall a nice day. A weak cold front will bring the risk of a few showers and thunderstorms Saturday, but this activity will likely be limited, favoring areas north and west of Boston earlier and Boston southward later. High pressure brings dry weather with some building heat Sunday through Monday along with an increase in humidity.
TODAY: Mostly sunny. Highs 77-85. Wind light N with coastal sea breezes.
TONIGHT: Mostly clear. Lows 56-63. Wind light variable.
FRIDAY: Partly sunny. Highs 75-83, coolest coast. Wind light SE.
SATURDAY: Variably cloudy. Isolated to scattered showers/thunderstorms. Lows 60-67. Highs 80-87.
SUNDAY: Mostly sunny. Lows in the 60s. Highs 83-90.
MONDAY: Mostly sunny. Lows 63-70. Highs 85-92.

DAYS 6-10 (AUGUST 18-22)…
Disturbance brings a shower and thunderstorm threat late August 18 into August 19 with above to near normal temperatures. Dry August 20-22 with briefly cooler August 20 then heat building August 21-22.

DAYS 11-15 (AUGUST 23-27)…
Temperatures near to above normal and rainfall near to below normal as high pressure ridging dominates the East Coast of the US.

Wednesday Forecast Update

7:33AM

DAYS 1-5…
Humidity will be much lower today but a disturbance with cold air aloft may trigger a few isolated afternoon showers and thunderstorms on an otherwise mainly dry day. Perseid Meteor Shower peaks tonight and early Thursday with the potential for seeing 60 to 100 meteors per hour in ideal conditions (away from city lights and after 11PM until just before the light of dawn). High pressure brings dry weather and lots of sun Thursday. An approaching warm front will increase some cloudiness during Friday but overall a nice day. A weak cold front will bring the risk of a few showers and thunderstorms Saturday, but this activity will likely be limited, favoring areas north and west of Boston earlier and Boston southward later. High pressure brings dry weather again Sunday.
TODAY: Early clouds departing eastern areas but other clouds popping up during the day. Isolated showers/thunderstorms this afternoon. Highs 75-80 Cape Cod and Islands, 80-85 elsewhere. Wind light W but may be gusty around any showers/storms.
TONIGHT: Partly cloudy early then mostly clear. Lows 58-65. Wind light NW.
THURSDAY: Mostly sunny. Highs 77-85. Wind light N with coastal sea breezes.

DAYS 6-10 (AUGUST 17-21)…
Limited shower/thunderstorm chances. Mainly rain-free. Temperatures above normal.

DAYS 11-15 (AUGUST 22-26)…
A few shower/thunderstorm episodes. Still mainly rain-free. Temperatures near to above normal.

Tuesday Forecast Update

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.

Monday Forecast Update

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.
TUESDAY: Cloudy. Numerous showers and a chance of thunderstorms especially in the afternoon. Humid. Highs in the 70s. Wind S 5-15 MPH.
WEDNESDAY: Partly cloudy. Isolated showers/thunderstorms possible. Lows in the 60s. Highs 77-84.
THURSDAY: Mostly sunny. Lows 56-63. Highs 75-82.
FRIDAY: Partly cloudy. Lows 56-63. Highs 77-84.

DAYS 6-10 (AUGUST 15-19)…
Seasonable warmth and more humid with a slight risk of a shower or thunderstorm weekend August 15-16. Additional showers/thunderstorms August 17-18 ending by August 19 with temperatures near to above normal.

DAYS 11-15 (AUGUST 20-24)…
High pressure ridge becomes more established with late August heat and humidity possible and limited rain chances.

Sunday Forecast Update

8:29AM

DAYS 1-5…
No major changes here other than a few tiny tweaks, so skip the discussion and right to the forecast today. Any questions can be addressed in the comment section as always!
TODAY: Partly sunny with most cloudiness morning and midday over eastern MA and southeastern NH. Highs 68-73 coast, 74-79 interior. Wind NE 5-15 mph.
TONIGHT: Partly cloudy. Lows 55-62. Wind light E.

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.

Saturday Update / Marine Weekend

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.
MONDAY: Increasing clouds. Lows 55-62. Highs in the 70s.
TUESDAY: Mostly cloudy. Showers/thunderstorms likely. Lows in the 60s. Highs in the 70s.
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.

Friday Forecast Update

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.

Thursday Forecast Update

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.

Wednesday Forecast Update

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.

Tuesday Forecast Update

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.

Monday Forecast Update

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.

Sunday Forecast Update

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.
THURSDAY: Mostly cloudy. Chance of rain especially South Coast. Lows 58-66. Highs 74-82.

DAYS 6-10 (AUGUST 7-11)…
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.
