DAYS 1-5 (JULY 20-24)…
An area of high pressure will provide sunshine and dry air today and Thursday, with a range in temperature from almost a little bit of a chill to start this morning to a mid summer feel by Thursday afternoon. Add humidity and more heat to the mix Friday, along with an approaching disturbance from the northwest, and the result will be scattered showers and thunderstorms. This will move away for the weekend but this time don’t expect a refreshing air mass behind it. Expect more heat and humidity.

Warm to hot, mostly dry weather July 25-27.

DAYS 11-15 (JULY 28-AUGUST 1)…
Scattered showers and thunderstorms favor early period then drier. Temperatures above normal.

7:59AM

DAYS 1-5 (JULY 17-21)…
Disturbances moving through the region today will trigger scattered showers and thunderstorms until late in the day. Heat blasts into the region Monday but a cold front slicing into it will likely set off more showers and thunderstorms from west to east during the afternoon. High pressure builds in with drier and less hot air Tuesday through midweek.
TODAY: Variably cloudy. More humid. Episodes of scattered showers/thunderstorms. Highs 77-83 immediate coast, 83-88 elsewhere. Wind light S to SE.

DAYS 11-15 (JULY 27-31)…
Very warm to hot. Showers/storms are most likely around the early to mid portion of this period.

9:00AM

DAYS 1-5 (JULY 16-20)…
Classic mid summer pattern underway with bouts of heat that ease at times. An old washed out frontal boundary and a disturbance or 2 may bring an isolated shower or thunderstorm to a few locations today and again Sunday, and a stronger cold front approaching will increase the risk of storms later Monday into Tuesday.
TODAY: Mostly sunny to partly cloudy. Slight risk of an isolated shower or thunderstorm in the afternoon but most areas will see nothing. Highs 78-85 Cape Cod / Islands, 85-92 elsewhere. Wind W 5-15 MPH.
TONIGHT: Partly to mostly cloudy. Isolated showers after midnight. Lows 63-72, warmest in urban areas. Wind light SW.
SUNDAY: Variably cloudy. Isolated showers and thunderstorms through late afternoon. Highs 77-82 South Coast, 83-89 elsewhere. Wind light SW but some coastal sea breezes.

DAYS 11-15 (JULY 26-30)…
Similar to the previous 5-days, warm to hot, humid at times, a few episodes of showers/thunderstorms but overall a below normal rainfall pattern.

7:28AM

DAYS 1-5 (JULY 15-19)…
A weakening cold front will hanging in the region today may trigger a few isolated showers and thunderstorms but otherwise a dry and hot day is on tap. There will be even less of a risk of an isolated storm on Saturday and the chance will be gone by Sunday. The hottest of the 3 days will be today. Humidity will lower during the next 3 days but make a come back early next week, as will the chance of thunderstorms are another weakening front moves into the vicinity.
TODAY: Mostly sunny to partly cloudy. Slight chance of isolated showers and thunderstorms this afternoon, especially eastern MA and RI. Humid. Highs 79-85 Cape Cod, 84-92 immediate shores, 92-97 elsewhere. Wind light W with a few weak sea breezes near the coast.
TONIGHT: Partly cloudy early then mostly clear. Less humid. Lows 65-73. Wind light W.
SATURDAY: Partly cloudy. Highs 84-92, cooler Cape Cod.
SUNDAY: Mostly sunny. Lows in the 62-70. Highs 84-92, cooler Cape Cod.

Warm/dry July 20-21. Heat/humidity, and risk of a few showers/thunderstorms July 22-24.

DAYS 11-15 (JULY 25-29)…
Above normal temperatures, drier than average but still some risk of a few showers/thunderstorms at times.

7:27AM

DAYS 1-5 (JULY 14-18)…
Typical July pattern. Today is going to be a humid one with a southerly to southwesterly wind and an approaching trough. A few scattered showers and possible thunderstorms will be around during the day but most of the time will be rain-free. A strong line of showers/thunderstorms will enter western New England at the end of the day but likely weaken considerably as it tracks to the east this evening. Some moderate to strong storms may survive the trip at least part-way so it will be something to monitor. Friday’s atmosphere will be hotter and only very slightly less humid but also less supportive for thunderstorm activity, with only a few possible around Cape Cod. A cold front will come through without much fanfare at night and take the edge off the humidity a bit further for the weekend. A disturbance will pass south of the region and may bring some high level cloudiness at times to southern areas but any wet weather will not reach the region. Humidity makes a come back by Monday as does the risk of showers and thunderstorms as winds turn southwest again.
TODAY: Partly sunny and hazy. Scattered to isolated showers and thunderstorms. Very humid. Highs 77-84 Cape Cod and immediate shores, 85-91 elsewhere. Wind S to SW 5-15 MPH gusting 20-25 MPH at times.
TONIGHT: Variably cloudy and hazy. Showers/thunderstorms moving eastward across the region before 11PM but weakening with time overall. Humid. Lows 66-73. Wind SW 5-15 MPH, higher gusts.
FRIDAY: Mostly sunny. Humid. Highs 79-86 Cape Cod and immediate shores, 87-95 elsewhere.
SATURDAY: Partly cloudy. Less humid. Lows 65-73. Highs 82-90, cooler Cape Cod.
SUNDAY: Mostly sunny. Lows in the 62-70. Highs 84-92, cooler Cape Cod.
MONDAY: Partly sunny. Scattered showers/thunderstorms especially late-day. More humid. Lows 64-72. Highs 85-93, cooler Cape Cod.

DAYS 6-10 (JULY 19-23)…
Sluggish cold front leaves a bit of heat and humidity and the risk of a shower or thunderstorm in the region July 19 before drier and a little less warm July 20. Warm to hot, more humidity, but limited chances of showers/thunderstorms July 21-23.

DAYS 11-15 (JULY 24-28)…
Above normal temperatures, drier than average but still some risk of a few showers/thunderstorms at times.

6:21AM

DAYS 1-5 (JULY 13-17)…
Overall ideas are the same, but some fine-tuning has resulted in adding a slightly better risk of showers and thunderstorms to the forecast for Thursday and lessening the risk for Friday, as it looks like the support in the atmosphere will be greatest through Thursday evening and less so thereafter. Adding a few showers/storms to Saturday’s forecast but far from a wash-out threat. Updated forecast…
TODAY: Partly cloudy. More humid. Highs 77-82 Cape Cod, 83-88 other shores, 88-93 elsewhere. Wind SW 5-15 MPH.
TONIGHT: Partly cloudy and hazy. Slight risk of isolated showers and thunderstorms especially south and west of Boston overnight. Humid. Lows 64-72, warmest urban areas. Wind light SW.
THURSDAY: Partly sunny and hazy. Isolated showers and thunderstorms possible during the day. Scattered or clustered showers/thunderstorms possible from west to east evening or night. Highs 76-83 Cape Cod and immediate shores, 84-91 elsewhere.
FRIDAY: Mostly sunny. Humid. Lows 66-73. Highs 77-85 Cape Cod and immediate shores, 86-94 elsewhere.
SATURDAY: Partly cloudy. Isolated showers/thunderstorms. Humid. Lows 65-73. Highs 82-90.
SUNDAY: Mostly sunny. Lows in the 62-70. Highs 84-92.

DAYS 6-10 (JULY 18-22)…
Moderate to high humidity at times, warm to hot temperatures, and a few episodes of showers and thunderstorms in the area as the overall pattern is more typical of mid summer.

DAYS 11-15 (JULY 23-27)…
Limited shower/thunderstorm chances early in the period may increase a bit later. Temperatures near to above normal.

7:04AM

DAYS 1-5 (JULY 12-16)…
High pressure takes control of the region today then gradually settles to the south of New England during midweek as a broad but low amplitude low pressure trough moves swiftly eastward across Canada through late week. The resultant weather here will be building heat and eventually humidity, then a risk of showers and thunderstorms, mainly isolated later Thursday and scattered during Friday. The timing and coverage of the Friday activity is very much uncertain at this point, as I think there will be one pre-frontal trough nearby earlier in the day and then a cold front moves into the region later in the day or at night. This front will settle just south of the region Saturday with mainly dry weather returning along with lowering humidity.
TODAY: Mostly sunny. Highs 75-80 Cape Cod, 80-85 most areas, 85-90 interior valleys. Wind W 5-15 MPH.
TONIGHT: Mostly clear. Lows 58-65. Wind light SW.
WEDNESDAY: Mostly sunny. More humid. Highs 77-82 Cape Cod, 83-88 other shores, 88-93 elsewhere. Wind SW 5-15 MPH.
THURSDAY: Partly cloudy. Isolated thunderstorms possible late day and early night. Humid. Lows 65-72. Highs 77-85 Cape Cod and immediate shores, 86-94 elsewhere.
FRIDAY: Partly sunny. Scattered thunderstorms possible afternoon and night. Humid. Lows 66-73. Highs 77-85 Cape Cod and immediate shores, 86-94 elsewhere.
SATURDAY: Partly cloudy. Less humid. Lows in the 60s. Highs in the 80s.

DAYS 6-10 (JULY 17-21)…
High pressure will hold off a passing low pressure wave south of New England on July 17 with fair and warm weather but not too humid. Humidity increases July 18-20 and the risk of showers/thunderstorms returns July 19-20 before subsiding July 21.

DAYS 11-15 (JULY 22-26)…
Limited shower/thunderstorm chances early in the period may increase a bit later. Temperatures above normal.

7:33AM

DAYS 1-5 (JULY 11-15)…
Lingering low level moisture and departing upper level low pressure will bring lots of clouds to start the day, then clouds/sun for the mid part of the day, then finally drier air pushes in later with more sun. The remainder of the period will feature more typical July weather as high pressure builds in through Wednesday, then relaxes to the south as a broad but flat trough pushes eastward across eastern Canada and sends a weakening front into the Northeast at the end of the week, increasing the risk of showers and thunderstorms somewhat.
TODAY: Mostly cloudy to partly sunny morning. Partly cloudy to mostly sunny afternoon. Highs from the middle 70s coast to lower 80s interior valley areas. Wind NE to N 5-15 MPH.
TONIGHT: Mostly clear. Lows from the middle 50s interior valleys to lower 60s urban areas. Wind light W.
TUESDAY: Mostly sunny. Highs in the 80s. Wind SW 5-15 MPH.
WEDNESDAY: Mostly sunny. More humid. Lows in the 60s. Highs from the upper 80s to middle 90s except cooler Cape Cod.
THURSDAY: Partly cloudy. Humid. Isolated late-day thunderstorms. Lows from the middle 60s to lower 70s. Highs from the upper 80s to middle 90s.
FRIDAY: Partly sunny. Humid. Scattered afternoon showers/thunderstorms. Lows from the upper 60s to lower 70s. Highs from the middle 80s to lower 90s.

DAYS 6-10 (JULY 16-20)…
A few showers may linger for part of July 16 then dry and warm for the remainder of the weekend through July 17. Very warm to hot, more humid pattern again with isolated to scattered showers/thunderstorms otherwise mainly dry weather July 18-20.

DAYS 11-15 (JULY 21-25)…
A couple episodes of isolated to scattered showers/thunderstorms in an otherwise mainly rain-free pattern. Temperatures above normal.

7:40AM

DAYS 1-5 (JULY 10-14)…
No big changes today. One more day for low pressure to finish its jelly-like squeeze across and just south of New England with upper levels cooling a bit and allowing a few more showers to pop up today. A hint of lingering trough Monday and some leftover low level moisture will allow for some clouds to pop up and possibly produce an isolated shower, but looking at a mainly dry day on Monday. Then true summer weather makes a run into the region Tuesday through Thursday as high pressure builds surface and aloft through Wednesday, then relaxes a little to the south as a weakening frontal boundary approaches the region by Thursday, possibly resulting in a few thunderstorms.
TODAY: Mostly cloudy. Scattered showers and a slight chance of a thunderstorm. Highs from the upper 60s coast to 70s elsewhere. Wind NE to N 5-15 MPH.
TONIGHT: Mostly cloudy with isolated showers in the evening. Partly cloudy overnight. Lows from the middle 50s to lower 60s. Wind N to NW 5-15 MPH.
MONDAY: Partly sunny. Risk of a few isolated showers. Highs from the upper 70s to lower 80s.
TUESDAY: Mostly sunny. Lows from the upper 50s to middle 60s. Highs in the 80s.
WEDNESDAY: Mostly sunny. More humid. Lows in the 60s. Highs from the upper 80s to middle 90s except cooler Cape Cod.
THURSDAY: Partly cloudy. Humid. Isolated late-day thunderstorms. Lows from the middle 60s to lower 70s. Highs from the upper 80s to middle 90s.

DAYS 6-10 (JULY 15-19)…
Very warm to hot and humid with isolated to scattered thunderstorms as weakening cold front pushes through the region during July 15.
Weekend of July 16-17 currently looks mainly dry and quite warm. Hot and more humid with isolated thunderstorms July 18-19.

DAYS 11-15 (JULY 20-24)…
A couple episodes of isolated to scattered showers/thunderstorms in an otherwise mainly rain-free pattern.

8:11AM

DAYS 1-5 (JULY 9-13)…
Complex but fairly weak low pressure will take the next 2 more days to squeeze itself mainly south of New England, keeping the WHW forecast area on the cool and damp side of if. As I mentioned in the previous update, this is mixed news depending on how you look at it, good news because it prevents severe weather and delivers at least some needed rain, but not as good news because it does not look like as widespread and beneficial a rainfall as many systems like this can produce, and also it makes it a poor weekend for many outdoor activities such as the beach. Though there will be scattered showers around mainly during this morning, much of the afternoon and early evening will turn out rain-free, and then later tonight into Sunday morning will come the greatest chance of showers overall. Additional showers are possible through later Sunday too as colder air comes in aloft and adds some instability to the atmosphere overall. As we enter the new week Monday, vast improvement will be noted, however some lingering moisture in the lower levels and cool air above will allow the development of some fair-weather clouds after any initial leftover cloudiness from the weekend system pulls away early. High pressure will build over the region both at the surface and aloft, resulting in a sunnier and warmer Tuesday. This process will continue Wednesday, which will be a little hotter and slightly more humid.
TODAY: Mostly cloudy. Spotty light showers and drizzle mainly this morning. Highs from the middle 60s to lower 70s. Wind E to NE 5-15 MPH.
TONIGHT: Mostly cloudy. Better chance of showers coming late at night. Slight chance of a thunderstorm. Lows from the lower to middle 60s. Wind SE 5-15 MPH.
SUNDAY: Mostly cloudy. Scattered showers and a slight chance of a thunderstorm. Highs from the upper 60s coast to 70s elsewhere. Wind NE to N 5-15 MPH.
MONDAY: Partly sunny. Lows from the middle 50s to lower 60s. Highs from the upper 70s to lower 80s.
TUESDAY: Mostly sunny. Lows from the upper 50s to middle 60s. Highs in the 80s.
WEDNESDAY: Mostly sunny. Lows in the 60s. Highs from the middle 80s to lower 90s except cooler Cape Cod.

DAYS 6-10 (JULY 14-18)…
A couple days of more classic summer heat expected July 14-15 and as a weakening cold front approaches and tries to push into the region, isolated thunderstorms are possible late in the day of July 14 and a few scattered thunderstorms may occur the afternoon of July 15. Weekend of July 16-17 currently looks mainly dry and quite warm. A few showers/storms may return by the end of the period July 18.

DAYS 11-15 (JULY 19-23)…
A couple episodes of isolated to scattered showers/thunderstorms in an otherwise mainly rain-free pattern. Temperatures above normal.

9:18AM

DAYS 1-5 (JULY 8-12)…
Complex but fairly weak low pressure will take the next 3 days to squeeze itself mainly south of New England, and with a small area of high pressure to the north for part of the time, we’ll be on the cool and non-severe weather side of this system. This part is good news. What could be better news but is not is that I don’t expected all that beneficial rain from it as it will be a disorganized system with weak upper level support as low pressure above it is stretched out. The best support in the upper levels may come as the system departs later Sunday. All in all the theme will be for spotty and very light showers most of the time, with a couple opportunities for a larger area of light to moderate showers coming through from time to time, mainly tonight and in the early hours of Sunday based on current timing. By Monday and Tuesday, we’ll re-emerge into a bright and dry weather pattern with a warming trend.
TODAY: Overcast through the morning with spotty very light rain/drizzle mainly south of Boston and an isolated heavier shower on Nantucket for a while. Mostly cloudy with isolated showers this afternoon. Highs from the middle to upper 60s coast, lower to middle 70s inland. Wind variable but mainly E 5-15 MPH.
TONIGHT: Partly cloudy early, then cloudy with a period of showers overnight. Lows in the upper 50s to lower 60s. Wind light E.
SATURDAY: Mostly cloudy. Spotty light showers and drizzle. Highs from the middle 60s to lower 70s. Wind E to NE 5-15 MPH.
SATURDAY NIGHT: Mostly cloudy. Better chance of showers coming late at night. Lows from the lower to middle 60s. Wind SE 5-15 MPH.
SUNDAY: Mostly to variably cloudy. Scattered showers and a slight chance of a thunderstorm. Highs from the upper 60s coast to 70s elsewhere. Wind NE to N 5-15 MPH.
MONDAY: Mostly sunny. Lows from the middle 50s to lower 60s. Highs from the upper 70s to lower 80s.
TUESDAY: Mostly sunny. Lows from the upper 50s to middle 60s. Highs from the lower to middle 80s.

DAYS 6-10 (JULY 13-17)…
High pressure at the surface and upper levels will bring fair and very warm to hot weather July 13-14 with gradually increasing humidity. Humid with a risk of showers/thunderstorms July 15-16 as a weakening front moves into the region. High pressure brings fair/warm weather back by the end of the period.

DAYS 11-15 (JULY 18-22)…
A similar pattern with fair and warm to hot weather to start, followed by more humidity and a risk of showers/thunderstorms.

8:16AM

DAYS 1-5 (JULY 7-11)…
Still turning the tuning knobs on this forecast but not a whole lot of change from the last post, with the issue regarding temperatures being the location of a boundary separating the hotter air mass that was over us Wednesday and a cooler marine layer of air that has pushed into southeastern NH and northeastern to east central MA during the early morning hours. I expected this boundary to waver around but slowly sink south to southwest overall through Friday, then try to make a run northeastward again Friday night and Saturday. I’m still leaning toward the idea of the boundary of warm air falling short of making it back across the entire region on Saturday, leaving areas north and east cooler. As for shower/thunderstorm chances, they exist today favoring areas near and to the warm side of the boundary, which will be east central MA and southwestern NH southward. Activity should be pushed further south tonight into Friday before making a northeastward return Friday night into Saturday. Another area of showers/storms should sweep eastward later Saturday along a cold front as the strongest low pressure area tracks north of New England. But an upper level trough still traversing the region Sunday with cooler air aloft may still trigger a few instability showers and thunderstorms. Finally by Monday, low pressure moving away and high pressure moving in should provide a dry, mild, and breezy day. I have not mentioned severe weather up to this point, regarding the thunderstorm chances, mainly because I think any severe storms would be of the isolated variety, rather than a larger scale organized outbreak as may have occurred had the warmer/muggy air stayed in more of the region for a longer time, but with contrast and instability around, I cannot rule out a few strong to severe storms.
TODAY: Clouds dominate but areas of sunshine especially interior east central to south central MA into adjacent RI/CT for a while. Sunniest area stand the greatest chance of showers/thunderstorms developing early to mid afternoon which will think sink southward. Storms may produce gusty winds, torrential rain, and hail. Elsewhere, lower risk but still isolated to scattered showers/thunderstorms possible. Highs range from the upper 60s seacoast of NH and eastern MA to the upper 80s in areas that are still sunny as of 8AM with a fairly sharp contrast between. Wind mostly E up to 10 MPH, but variable over some interior areas, except briefly strong/gusty near any storms.
TONIGHT: Mostly cloudy. A few showers/thunderstorms possible. Areas of fog especially South Coast and Cape Cod. Humid. Lows in the 60s. Wind light E to NE.
FRIDAY: Mostly cloudy. Isolated showers possible. Highs upper 60s eastern coastal areas, 70s elsewhere. Wind NE 5-15 MPH.
SATURDAY: Mostly cloudy. Episodes of showers/thunderstorms. Lows in the 60s. Highs in the 70s.
SUNDAY: Partly cloudy. Isolated showers/thunderstorms. Lows in the 60s. Highs from the upper 70s to middle 80s.
MONDAY: Mostly sunny. Lows from the middle 50s to lower 60s. Highs from the upper 70s to lower 80s.

DAYS 6-10 (JULY 12-16)…
Dry weather July 12-14 with a slow build of heat/humidity. Shower/thunderstorm risk increases as it continues humid later in the period.

DAYS 11-15 (JULY 17-21)…
Dry and a little cooler early in the period then heating up again with isolated showers/thunderstorms later in the period.

2:08AM

DAYS 1-5 (JULY 6-10)…
After a whole lot of analysis of data during the last 12 hours leading up to the writing of this blog entry, I’ll be making a few adjustments to the forecast overall but with the general idea still the same – heat today, then a boundary nearby with temperatures depending on location of the boundary, and shower/thunderstorm chances depending on timing of disturbances and locations of boundaries, with a greater-than-usual amount of uncertainty for the remainder of the period. The current thinking is that more of the region than not will be on the cooler side of the boundary Thursday and Friday with a risk of showers/thunderstorms both days, but possibly favoring late Thursday as activity is slow to arrive, and then less of a risk for a while on Friday as activity is pushed further to the southwest. This boundary will likely make an attempt to return as a warm front Friday night into Saturday but it is uncertain how far it will get, with the greatest chance of getting into the warm/humid air the further west and south you are. This would end up being the region with the greatest risk of stronger storms. Again, timing and placement being uncertain, there will still be much fine-tuning to do. By Sunday, though the main cold front from the weekend system should be by, enough instability may remain as the trough is slow to pass at upper levels, and this may allow for some additional scattered shower and thunderstorm activity. This is a change from the previous forecast. So, with medium to lower confidence, here is the latest forecast update, but check back for updates!
TODAY: Mostly sunny. Humid then slightly drier. Highs from the middle to upper 80s immediate coast, lower to middle 90s otherwise. Wind light W except sea breezes at shoreline locations.
TONIGHT: Partly cloudy. Lows from the middle 60s to lower 70s. More humid. Wind light variable.
THURSDAY: Mostly cloudy. Isolated to scattered showers/thunderstorms. Highs from the middle to upper 70s eastern coastal areas, upper 70s to middle 80s most other areas except some upper 80s to lower 90s in interior MA, northern RI, and northeastern CT. Wind variable, mainly E to NE up to 10 MPH near eastern coastal areas and mainly SE to S up to 15 MPH elsewhere.
FRIDAY: Variably cloudy. Isolated showers possible. Lows in the 60s. Highs 70s coast, 80s interior.
SATURDAY: Mostly cloudy. Episodes of showers/thunderstorms. Lows in the 60s. Highs in the 70s.
SUNDAY: Partly cloudy. Isolated showers/thunderstorms. Lows in the 60s. Highs from the upper 70s to middle 80s.

DAYS 6-10 (JULY 11-15)…
Dry weather expected July 11-14, starting out with mild/dry weather then trending toward hot/humid. Showers/thunderstorms become more likely at the end of the period.

DAYS 11-15 (JULY 16-20)…
Showers/thunderstorms may be around to start the period followed by drier and warm weather. Heat may try to return later in the period.
