7:10AM

DAYS 1-5 (JULY 10-14)
We are now at the start of the middle of the middle of Meteorological Summer, which is a fancy way of saying July 10. But regardless of how you say it, the weather is pretty easy to describe today and can be done so with 2 words: sunny, hot. This weather will be achieved as high pressure sinks to the south of the region, but it’s really only a one-day blast of heat with a bit humidity thrown in, as a cold front dropping down from northern New England will put a quick end do it as it goes by the region tonight. The front is not accompanied by a tremendous amount of storm support, so not looking for any widespread rain/storms, however a few showers and thunderstorms will pop up along the front this afternoon to the north of this area, and some will stray into southern New England this evening and early tonight. High pressure builds in from eastern Canada with cooler air for Wednesday and Thursday. However clouds and a shower threat may linger over the South Coast and Cape Cod through midday Wednesday. In additional, there may be just enough lift from a sea breeze boundary to pop a shower just back from the eastern coastal areas Thursday afternoon, otherwise dry weather is expected during midweek. Forecast Hurricane Chris will pass out to sea to the southeast of New England after all, but will create some increased seas and coastal surf in the area later this week. High pressure sinks to the south but maintains control late in the week, when it will heat up a little more, though the high humidity will be kept at bay. Forecast details…
TODAY: Sunny through afternoon then increasing clouds north to south evening. More humid. Highs 83-88 South Coast and Cape Cod, 88-95 elsewhere. Wind W 5-15 MPH.
TONIGHT: Variably cloudy. Isolated showers and thunderstorms from north to south. Humid early, then drying. Lows 62-68. Wind shifting to N 5-15 MPH.
WEDNESDAY: Variably cloudy with isolated showers South Coast through midday then clearing. Mostly sunny elsewhere. Highs 73-78 eastern coastal areas and Cape Cod, 78-83 elsewhere. Wind NE 5-15 MPH.
WEDNESDAY NIGHT: Clear. Patchy fog interior low lying locations. Lows 53-58 interior lowlands, 58-63 elsewhere. Wind light variable.
THURSDAY: Sunny to partly cloudy. Slight risk of an isolated shower southeastern NH and eastern MA in the afternoon. Highs 75-80 coast, 80-85 interior. Wind light variable with sea breezes.
FRIDAY: Mostly sunny. Lows from the upper 50s to middle 60s. Highs in the 80s.
SATURDAY: Mostly sunny. Lows in the 60s. Highs from the lower 80s to around 90, coolest coastal areas.

DAYS 6-10 (JULY 15-19)
Warmer to hot, a bit more humid, but dry weather July 15-16. Showers/thunderstorms July 17 with high humidity leading to a cooling and drying trend by the middle of next week as another trough drops out of Canada.

DAYS 11-15 (JULY 20-24)
The pattern we’re currently in and expected to be in for the coming 10 days may repeat in a weaker fashion here as high pressure tries to build off the Atlantic Coast. Low confidence forecast at this time.

6:55AM

DAYS 1-5 (JULY 9-13)
High pressure sinks to the south of the region and allows heat into the region early this week, but still dry today before some humidity increase Tuesday, though neither heat nor humidity will be to the level of what was seen last week. A cold front will cross the region Tuesday night and ahead of it a few showers or thunderstorms are possible from late Tuesday afternoon to the early hours of Wednesday. High pressure builds in at midweek and not only will bring drier and somewhat cooler air, but should play a role in keeping Chris, forecast to be a hurricane, mainly offshore. Leaning a little more to this being the case rather than the sneaker closer pass, but leaving showers in the forecast for Cape Cod Thursday just in case. High pressure moves over then south of the region Friday, which will end up a warmer day. Forecast details…
TODAY: Sunny. Highs 78-85 South Coast, 86-93 elsewhere. Wind W 5-15 MPH.
TONIGHT: Mostly clear. Lows 60-67. Wind SW up to 10 MPH.
TUESDAY: Partly cloudy. Isolated thunderstorms possible far north and west of Boston by late day. More humid. Highs 78-85 South Coast, 86-93 elsewhere. Wind SW 5-15 MPH.
TUESDAY NIGHT: Variably cloudy. Isolated showers and thunderstorms. Humid. Lows 65-72. Wind SW up to 10 MPH but may be variable and gusty near any storms.
WEDNESDAY: Mostly sunny. Less humid. Highs 75-83. Wind N 5-15 MPH.
THURSDAY: Partly cloudy. Risk of showers Cape Cod. Lows from the upper 50s to middle 60s. Highs from the upper 70s to middle 80s.
FRIDAY: Mostly sunny. Lows in the 60s. Highs in the 80s, cooler some coastal areas.

DAYS 6-10 (JULY 14-18)
A warm to hot July 14-15 weekend with no more than isolated showers and thunderstorms. A front in the area may trigger additional showers and storms sometime in the July 16-18 period, but most of the time will likely be rain-free with near to above normal temperatures.

DAYS 11-15 (JULY 19-23)
Overall pattern remains warm with a couple shower and thunderstorm threats, but largely dry weather overall.

8:15AM

DAYS 1-5 (JULY 8-12)
Just a quick update today. High pressure maintains control, looking like through Tuesday at this time, and still watching the offshore tropical system during midweek. Odds favor it staying offshore at this point, but need to keep an eye on it, especially Cape Cod. If nothing else, it will be increase the seas in the region.
TODAY: Sunny. Highs 77-85. Wind light variable.
TONIGHT: Clear. Lows 57-64. Wind light SW.
MONDAY: Sunny. Highs 78-85 South Coast, 85-92 elsewhere. Wind W 5-15 MPH.
MONDAY NIGHT: Clear. Lows 60-68. Wind light W.
TUESDAY: Partly cloudy. Highs 78-85 South Coast, 85-92 elsewhere. Wind SW 5-15 MPH.
WEDNESDAY & THURSDAY: Variably cloudy. Possible coastal showers. Lows in the 60s. Highs from the upper 70s to middle 80s.

DAYS 6-10 (JULY 13-17)
Fair early and late period with a shower and thunderstorm threat mid period. Temperatures near to above normal.

DAYS 11-15 (JULY 18-22)
A west to east flow will carry a couple disturbances producing shower and thunderstorm threats in passing, but the overall pattern is on the drier side with near to above normal temperatures.

9:17AM

DAYS 1-5 (JULY 7-11)
Simply beautiful weekend as high pressure dominates, then as it sinks to the south a little summer heat, without humidity arrives Monday. Tuesday-Wednesday we will see warmth and an increase in humidity but have to start watching a tropical system off the East Coast. Though computer guidance currently takes this system offshore, there are some subtle things these models can miss that leave open the door for that system to come closer or even over the region as early as later Tuesday, so the wording for Tuesday and Wednesday in the forecast below will be vague and a little lower confidence than usual for this time period.
TODAY: Sunny. Highs 75-82. Wind NW 5-15 MPH.
TONIGHT: Clear. Lows 55-62. Wind light N.
SUNDAY: Sunny. Highs 77-85. Wind light variable.
SUNDAY NIGHT: Clear. Lows 57-64. Wind light SW.
MONDAY: Sunny. Highs 78-85 South Coast, 85-92 elsewhere. Wind W 5-15 MPH.
TUESDAY: Increasing clouds. Chance of showers or rain at night. Lows in the 60s. Highs in the 80s.
WEDNESDAY: Mostly cloudy with a chance of rain or showers early, then partly cloudy. Lows in the 60s. Highs from the upper 70s to middle 80s.

DAYS 6-10 (JULY 12-16)
Shower threat early in the period from nearby tropical moisture. Jet stream systems bring shower and thunderstorm threats around July 13 and 16. Temperatures near to above normal.

DAYS 11-15 (JULY 17-21)
A west to east flow will carry a couple disturbances producing shower and thunderstorm threats in passing, but the overall pattern is on the drier side with near to above normal temperatures.

7:15AM

DAYS 1-5 (JULY 6-10)
Trough passes through this morning followed by a cold front midday and afternoon. Most of the moisture and energy for showers and thunderstorms is with the trough with less available for the front so the majority of the activity should be taking place before noon for a good portion of the region but will take until mid afternoon to pass through all of the southeastern areas before exiting. This marks an end to the current spell of heat and humidity and will be followed by a refreshing air mass through the weekend. Some heat returns early next week but without humidity getting all that high, though it will be a little more humid by Tuesday. Forecast details…
TODAY: Variably cloudy. Areas of showers and thunderstorms favoring areas west and north of Boston through midday and south of Boston into the afternoon. A few storms may be strong. Humid. Highs 78-86. Wind SW 10-20 MPH shifting to NW from north to south during the day.
TONIGHT: Clearing. Drier. Lows 56-64. Wind NW 5-15 MPH.
SATURDAY: Sunny to partly cloudy. Highs 75-82. Wind NW 5-15 MPH.
SATURDAY NIGHT: Mostly clear. Lows 55-62. Wind light N.
SUNDAY: Sunny. Highs 77-85. Wind light variable.
MONDAY: Sunny. Lows from the upper 50s to middle 60s. Highs in the 80s.
TUESDAY: Partly cloudy. Lows in the 60s. Highs in the 80s.

DAYS 6-10 (JULY 11-15)
A series of disturbances will battle what wants to be the return of heat and this will bring a few opportunities for showers and thunderstorms with variable but near seasonable temperatures overall.

DAYS 11-15 (JULY 16-20)
A bit of settling but overall the same pattern continues with a couple shower and thunderstorm opportunities but variable but overall seasonable to slightly above normal temperatures.

9:49AM

DAYS 1-5 (JULY 5-9)
One more day of full heat under a ridge of high pressure before a cold front slices through the region and puts an end to it. The timing of this front is critical in determining the strength of thunderstorms. There are also a couple of troughs on either side of it, so more than one wave of storms is possible. It does look like the timing will be early enough to prevent maximum storm potential at least north and west of Boston. If enough sun is present south of Boston, where the front doesn’t get there quite as early, there may be some stronger storms. Some of the short range guidance has also shown a second area of storms north of Boston early to mid afternoon so while I may not fully buy this, it’s not being dismissed outright either. Regardless, by the evening, the front will be through the region and a refreshing air mass will be inbound, and ready to provide a very comfortable weekend. By Monday, we’ll already be into a new warm up, but not seeing signs of the same level of heat we’re currently experiencing. Forecast details…
TODAY: Sunny. Humid. Highs 82-89 South Coast, 90-98 elsewhere. Wind SW 5-15 MPH.
TONIGHT: Partly cloudy. Humid. Lows 68-77, warmest urban areas. Wind SW 5-15 MPH.F
FRIDAY: Variably cloudy. Areas of showers and thunderstorms favoring areas west and north of Boston through midday and south of Boston into the afternoon. A few storms may be strong. Humid. Highs 78-86. Wind SW 10-20 MPH shifting to NW from north to south during the day.
FRIDAY NIGHT: Clearing. Drier. Lows 56-64.Wind NW 5-15 MPH.
SATURDAY: Sunny to partly cloudy. Highs 77-85. Wind NW 5-15 MPH.
SUNDAY: Sunny. Lows from the middle 50s to lower 60s. Highs from the upper 70s to middle 80s.
MONDAY: Sunny. Lows from the upper 50s to middle 60s. Highs in the 80s.

DAYS 6-10 (JULY 10-14)
A series of disturbances will battle what wants to be the return of heat and this will bring a few opportunities for showers and thunderstorms with variable but near seasonable temperatures overall.

DAYS 11-15 (JULY 15-19)
A bit of settling but overall the same pattern continues with a couple shower and thunderstorm opportunities but variable but overall seasonable to slightly above normal temperatures.

6:36AM

DAYS 1-5 (JULY 4-8)
Hot ridge continues to dominate on this Independence Day and will do so through tomorrow before relaxing is grip and heading westward to some degree late in the week, allowing a trough to dip out of Canada. There are no significant changes to this forecast which will pretty much look like an update of the previous. Still have to work out Friday’s timing to determine the coverage and intensity of thunderstorms. Before that, we will see a few more pop up storms today, in 2 rounds, but more isolated than yesterday and this time mainly to the south. Forecast details…
TODAY – INDEPENDENCE DAY: Areas of fog early. Partly cloudy to mostly sunny. Isolated showers and thunderstorms in southeastern MA, RI, and southeastern CT by mid morning, then another round of isolated storms in similar locations to as far north as the Mass Pike area this afternoon. Humid. Highs 78-86 immediate shorelines and Cape Cod, 87-96 elsewhere, hottest interior valleys. Wind light variable with light coastal sea breezes.
TONIGHT: Mostly clear. Humid. Lows 67-77, warmest in urban areas. Wind light variable.
THURSDAY: Mostly sunny. Humid. Highs 80-88 South Coast, 88-97 elsewhere, hottest interior valleys. Wind W up to 10 MPH.
FRIDAY: Partly sunny. Thunderstorms likely, favoring the afternoon and evening. Humid. Lows from the upper 60s to middle 70s. Highs from the middle 80s to middle 90s.
SATURDAY: Partly cloudy. Less humid. Lows in the 60s. Highs from the upper 70s to middle 80s.
SUNDAY: Mostly sunny. Lows from the upper 50s to middle 60s. Highs from the upper 70s to middle 80s.

DAYS 6-10 (JULY 9-13)
Dry and seasonably warm July 9. Showers/thunderstorms possible with a passing disturbance July 10 and watching another for late in the period with fair weather in between.

DAYS 11-15 (JULY 14-18)
A couple passing disturbances bring changeable but overall seasonable temperatures and a couple thunderstorm threats during this period.

7:05AM

DAYS 1-5 (JULY 3-7)
High pressure ridge dominates with hot weather into Friday. Air mass pop up thunderstorms are possible but only in isolated locations favoring west and northwest of Boston later today, and mainly west and south of Boston on Wednesday. The next thunderstorm threat will come in a more widespread way during Friday afternoon and evening as a cold front moves through the region. This will bring cooler and drier weather for the area by Saturday. Forecast details…
TODAY: Mostly sunny to partly cloudy. Slight chance of isolated thunderstorms late afternoon mainly southwestern NH and central MA. Humid. Highs 80-89 immediate South Coast and Cape Cod, 90-98 elsewhere, hottest interior valleys. Wind SW 5-15 MPH.
TONIGHT: Partly cloudy to mostly clear. Humid. Lows 65-75, warmest urban centers. Wind light variable.

SATURDAY: Partly cloudy. Less humid. Lows in the 60s. Highs from the upper 70s to middle 80s.

DAYS 6-10 (JULY 8-12)
July 8-9 look dry and seasonably warm. A disturbance coming along the jet stream brings a shower/thunderstorm threat July 10-11. Fair weather returns to end the period.

DAYS 11-15 (JULY 13-17)
A couple passing disturbances bring changeable but overall seasonable temperatures and a couple thunderstorm threats during this period.

8:46AM

DAYS 1-5 (JULY 2-6)
A modified batch of marine air sits over the region to start today and will be eroded and transformed to become part of the hot air mass under the high pressure ridge in the eastern US. This will take place during today and be in full force by tomorrow, and the heat will be in full control through midweek, save for a few coastal sea breezes. The only rain chance would be an isolated pop up air mass thunderstorm late Tuesday and sometime Wednesday afternoon, and these would favor interior locations. Thursday looks too stable to support any of these. However, something will be going on to our north on Thursday, the only visual evidence we will probably see of it will be some cloud patches in the northwest and north sky late in the day, from thunderstorms that erupted ahead of a cold front moving in from Canada. This front will proceed southeastward and bring thunderstorms to this area during Friday (timing to be figured out). Forecast details…
TODAY: Mostly sunny. Humid. Highs 77-85 immediate shore, 86-94 interior. Wind light E to SE becoming S late.78-86 immediate South Coast and Cape Cod, 87-96 elsewhere, hottest interior valleys.
TONIGHT: Mostly clear. Humid. Lows 64-72. Wind light S to SW.
TUESDAY: Mostly sunny to partly cloudy. Slight chance of isolated thunderstorms late afternoon mainly southwestern NH and central MA. Humid. Highs 80-89 immediate South Coast and Cape Cod, 90-98 elsewhere, hottest interior valleys. Wind SW 5-15 MPH.
TUESDAY NIGHT: Partly cloudy to mostly clear. Humid. Lows 65-75, warmest urban centers. Wind light variable.
WEDNESDAY – INDEPENDENCE DAY: Mostly sunny to partly cloudy. Isolated afternoon thunderstorms possible, mainly southwestern NH, central MA, northern RI, and northeastern CT. Humid. Highs 78-86 immediate shorelines and Cape Cod, 87-96 elsewhere, hottest interior valleys. Wind light variable with light coastal sea breezes.
THURSDAY: Mostly sunny. Humid. Lows from the upper 60s to upper 70s. Highs from the upper 80s to upper 90s but cooler in some coastal areas.
FRIDAY: Partly sunny. Thunderstorms likely, favoring the afternoon and evening. Humid. Lows from the upper 60s to middle 70s. Highs from the middle 80s to middle 90s.

DAYS 6-10 (JULY 7-11)
July 7-9 look dry and seasonably warm. A disturbance coming along the jet stream brings a shower/thunderstorm threat July 10-11.

DAYS 11-15 (JULY 12-16)
A couple passing disturbances bring changeable but overall seasonable temperatures and a couple thunderstorm threats during this period. The pattern will feature the ridge of high pressure having backed up to the west and a weak trough in the Northeast carrying the disturbances.

7:52AM

DAYS 1-5 (JULY 1-5)
No big changes, just a few adjustments to yesterday’s post. Slight, and I mean very slight, weakening of the westward push of the boundary but it will still create a wind shift and some cooling later today, and this will actually take all the way until early Tuesday to reverse itself, so the heat potential for Monday is somewhat tempered as well. Tempted to introduce isolated air mass storms Tuesday and Wednesday but will hold off for now. Forecast details…
TODAY: Partly cloudy to mostly sunny. Highs 79-86 shoreline and 87-95 elsewhere but falling back through the 70s immediate coast and through the 80s for up to about 20 miles inland from east-facing shores during the afternoon. Wind NW up to 10 MPH shifting to E and NE.
TONIGHT: Mostly clear. Lows 65-71. Wind light E.
MONDAY: Mostly sunny. Highs 78-85 immediate shore, 86-94 interior. Wind light E to SE becoming S late.
TUESDAY: Mostly sunny. Lows from the upper 60s to upper 70s, warmest urban areas. Highs from the upper 80s to middle 90s, coolest coastal areas.
WEDNESDAY – INDEPENDENCE DAY: Partly cloudy. Lows from the upper 60s to upper 70s. Highs from the upper 80s to middle 90s but cooler in some coastal areas.
THURSDAY: Mostly sunny. Lows from the upper 60s to upper 70s. Highs from the upper 80s to middle 90s but cooler in some coastal areas.

DAYS 6-10 (JULY 6-10)
Indications of a little quicker timing of a front that can bring a thunderstorm threat by later July 6 after one more hot and humid day. Weekend of July 7-8 currently looks less hot, still warm, and drier, with similar weather July 9 before a disturbance brings a shower and thunderstorm threat by the end of the period. Timing uncertain as always so far in advance.

DAYS 11-15 (JULY 11-15)
A couple passing disturbances bring changeable but overall seasonable temperatures and a couple thunderstorm threats during this period. The pattern will feature the ridge of high pressure having backed up to the west and a weak trough in the Northeast carrying the disturbances.

8:37AM

DAYS 1-5 (JUNE 30-JULY 4)
Not much new on this update, just a few tweaks. A disturbance passing through Maine should keep its showers and storms northeast of the WHW forecast area today and tonight but will watch it and alert in comments section later if something does end up a little closer than expected, and that would be southeastern NH or northeastern MA if it did happen, and sometime tonight. This disturbance, and the outflow from the storms associated with it, will push a boundary with a little more momentum into eastern areas during Sunday, sparing the coast the highest heat. This will penetrate inland some distance, but the impact is much less by the time we reach this time of year than it would have been earlier in the spring, and with the heat already in place, we’re starting at a much higher level before knocking things back. This air will hang around into Monday but the air mass will warm under the early July sunshine so don’t expect refreshing ocean wind everywhere, although the coast may still be quite comfy Monday, despite the air being rather humid. The hottest days of this period for the region overall should be Tuesday and Wednesday. There is only the slightest risk of an isolated thunderstorm Wednesday but the chance is so remote I hesitate to even mention it. I believe warm air aloft should keep it stable enough to overcome a little surface convergence and the heat/humidity at the ground. But where it is the holiday itself, the forecast is high stakes and will of course be closely monitored.
Forecast details…
TODAY: Mostly sunny. Highs 76-82 Cape Cod, 80-87 South Coast, 86-93 elsewhere. Wind W to SW up to 10 MPH.
TONIGHT: Mostly clear. Lows 66-75, warmest in urban areas. Wind light SW.
SUNDAY: Mostly sunny. Highs 78-85 shoreline and 86-95 elsewhere but falling back through the 70s immediate coast and through the 80s for up to 25 miles inland from east-facing shores during the late morning and afternoon. Wind SW up to 10 MPH shifting to E and NE.
MONDAY: Sunny. Lows from the upper 60s to upper 70s, warmest urban areas. Highs from the upper 70s to lower 80s immediate coast, ranging up from middle 80s to middle 90s further inland.
TUESDAY: Mostly sunny. Lows from the upper 60s to upper 70s, warmest urban areas. Highs from the upper 80s to middle 90s, coolest coastal areas.
WEDNESDAY – INDEPENDENCE DAY: Partly cloudy. Lows from the upper 60s to upper 70s. Highs from the upper 80s to middle 90s but cooler in some coastal areas.

DAYS 6-10 (JULY 5-9)
Currently expecting hot and humid weather but no storm threat July 5, and similar but with an isolated storm threat July 6 and 7. Better risk of showers/storms July 8 with a cold front and the hot weather pattern is broken, at least temporarily, by the end of the period.

DAYS 11-15 (JULY 10-14)
Less heat, back to more seasonable temperatures as the ridge backs up further west and a couple disturbances move through with shower and thunderstorm chances.

7:27AM

DAYS 1-5 (JUNE 29-JULY 3)
When Independence Day falls on a Wednesday, there is a perfect reason to have TWO “Fourth of July Weekends”, and they are both included in this outlook, the first one rapidly approaching, and it will be hot and increasingly humid as an upper level high pressure ridge takes over the weather. In fact, other than the remotest risk of a shower north and west of Boston this evening with a weak disturbance, I now do not see any possibility of rain for the remainder of this period, just plenty of heat, although there will be episodes of cooling sea breezes in some coastal areas, especially Sunday and Monday as it stands now. Forecast details…
TODAY: Sunshine, few clouds late. Highs 78-85 shorelines, 85-92 elsewhere. Wind NW up to 10 MPH with light coastal sea breezes.
TONIGHT: Partly cloudy evening with a slight risk of a brief shower west and north of Boston. Clearing overnight. Lows 62-69. Wind light variable.
SATURDAY: Mostly sunny. Highs 76-82 Cape Cod, 80-87 South Coast, 86-93 elsewhere. Wind W to SW up to 10 MPH.
SATURDAY NIGHT: Mostly clear. Lows 66-75, warmest in urban areas. Wind light SW.
SUNDAY: Mostly sunny. Highs 78-85 Cape Cod, 86-95 elsewhere. Wind SW up to 10 MPH but coastal sea breezes likely, especially east-facing shores which may drop to the 70s.
MONDAY: Sunny. Lows from the upper 60s to upper 70s, warmest urban areas. Highs from the upper 80s to middle 90s but cooling in some coastal areas.
TUESDAY: Mostly sunny. Lows from the upper 60s to upper 70s, warmest urban areas. Highs from the upper 80s to middle 90s, coolest coastal areas.

DAYS 6-10 (JULY 4-8)
More heat and humidity, but the thunderstorm chance may increase somewhat toward the end of the period as the ridge center shifts a little to the west and a disturbance or two get closer to the region.

DAYS 11-15 (JULY 9-13)
Less heat, back to more seasonable temperatures as the ridge backs up further west and a couple disturbances move through with shower and thunderstorm chances.

7:23AM

DAYS 1-5 (JUNE 28-JULY 2)
A warm front passes through this morning and a cold front approaches later today. Most of the support for widespread showers and embedded thunderstorms lies with the warm front and we’ll see this with another round of soaking showers crossing the region through midday. During the afternoon activity becomes scattered to isolated, but any storms that do form can be strong, so we need to watch for that. All quiets down this evening and then we shift focus to the incoming heat, initially with lower humidity Friday after today’s mugginess, and then building humidity returns thereafter. Forecast details…
TODAY: Mostly cloudy with showers likely and possibly a thunderstorm morning. Partly sunny with isolated showers and possible thunderstorms afternoon. Any thunderstorms can be briefly strong with downpours and gusty winds. Humid. Highs 75-82. Wind SW 10-20 MPH with higher gusts.
TONIGHT: Clearing. Patchy fog. Humid evening, less humid overnight. Lows 58-65. Wind W 5-15 MPH.
FRIDAY: Mostly sunny. Highs 78-85 South Coast, 85-92 inland. Wind W 5-15 MPH.
SATURDAY: Sunny. Lows in the 60s. Highs from near 80 South Coast to around 90 elsewhere.
SUNDAY: Sunny. Humid. Lows from the middle 60s to lower 70s. Highs from the lower to middle 80s South Coast, upper 80s to middle 90s elsewhere.
MONDAY: Sunny. Humid. Lows from the upper 60s to middle 70s. Highs from the middle 80s to middle 90s, coolest South Coast.

DAYS 6-10 (JULY 3-7)
An old frontal boundary may trigger a shower or thunderstorms July 3. Another front may approach later in the period with a shower and thunderstorm threat, but otherwise it’s fair and hot as high pressure ridging dominates. Sea breezes may cool coastal areas at times.

DAYS 11-15 (JULY 8-12)
As high pressure ridging slides back to the west the jet stream will be allowed to sink southward and provide a few more shower and thunderstorm threats with more variable temperatures during this period.

7:08AM

DAYS 1-5 (JUNE 27-JULY 1)
A warm front approaches today and passes tonight with more cloudiness (than previously forecast) but still not a bad day, and showers holding off until late evening and overnight, which will become more numerous through Thursday morning ahead of a cold front, which will pass through during the afternoon. But the air behind this front is not really much cooler than the air ahead of it. It’s more of a dew point boundary that will push out a wedge of high humidity that arrives overnight and early Thursday. So Friday will be less humid but will turn very warm as high pressure ridging builds over the eastern US. This sets up a hot weekend to end June and begin July. Forecast details…
TODAY: Limited sun through lots of high clouds. Highs 76-83. Wind S up to 10 MPH.
TONIGHT: Mostly cloudy. Showers arriving west to east late evening and overnight. Lows 60-67. Wind S 5-15 MPH.
THURSDAY: Mostly cloudy with showers likely and possibly a thunderstorm morning. Partly sunny with isolated showers and possible thunderstorms afternoon. Any thunderstorms can be briefly strong with downpours and gusty winds. Humid. Highs 75-82. Wind SW 10-20 MPH with higher gusts.
FRIDAY: Mostly sunny. Lows from the upper 50s to middle 60s. Highs from the middle 80s to lower 90s except cooler some coastal areas.
SATURDAY: Sunny. Lows in the 60s. Highs from near 80 South Coast to around 90 elsewhere.
SUNDAY: Sunny. Humid. Lows from the middle 60s to lower 70s. Highs from the lower to middle 80s South Coast, upper 80s to middle 90s elsewhere.

DAYS 6-10 (JULY 2-6)
A ridge of high pressure will dominate the weather and this is a hot pattern for this area with mainly dry weather. Exceptions are disturbances that travel over the ridge, which will be centered to the west of New England, sometimes can bring brief thunderstorm threats. A weakening front may make it into the vicinity around July 3 and trigger a few storms. Also some coastal areas can cool at times due to sea breezes.

DAYS 11-15 (JULY 7-11)
As high pressure ridging slides back to the west the jet stream will be allowed to sink southward and provide a few more shower and thunderstorm threats with more variable temperatures during this period.

7:38AM

DAYS 1-5 (JUNE 26-30)
No changes again. Two great days, then a front, favoring faster timing still, then heat knocks on the door at the end of the week.
Forecast details…
TODAY: Mostly sunny. Highs 76-83. Wind W 5-15 MPH.

DAYS 6-10 (JULY 1-5)
A ridge of high pressure will dominate the weather and this is a hot pattern for this area with mainly dry weather. Exceptions are disturbances that travel over the ridge, which will be centered to the west of New England, sometimes can bring brief thunderstorm threats. Also some coastal areas can cool at times due to sea breezes.

DAYS 11-15 (JULY 6-10)
Similar pattern continues with heat and limited thunderstorm chances at first, and then a couple stronger disturbances may bring better thunderstorm chances and cut into the heat thereafter.
