7:14AM

DAYS 1-5 (MAY 11-15)
Upper level low pressure departs through Friday and another one moves into the northeastern US from west to east this weekend through Monday. This keeps the unsettled weather pattern going, first with mainly just cloudiness dominating. The arrival of the next low will kick off a surface storm that is expected to bring some significant rain by Saturday night into Sunday.
TODAY: Mostly cloudy. Slight chance of showers. Highs 50-55 coast, 55-60 interior. Wind N to NE 5-15 MPH.
TONIGHT: Mostly cloudy. Slight chance of showers. Lows 42-47. Wind light NE.
FRIDAY: Mostly cloudy. Slight chance of showers. Highs 50-55 coast, 55-60 interior. Wind NE 5-15 MPH.
FRIDAY NIGHT: Mostly cloudy. Lows 42-47. Wind light NE.
SATURDAY: Cloudy. Rain develops afternoon and continues at night. Highs 48-53 coast, 53-58 interior. Wind E 5-15 MPH.
SUNDAY: Overcast. Rain, possibly heavy, tapering to lighter rain/drizzle. Lows in the 40s. Highs from the upper 40s to middle 50s.
MONDAY: Mostly cloudy. Brief mix possible higher elevations early otherwise isolated showers. Lows from the middle 30s to lower 40s. Highs from the upper 40s to middle 50s.

DAYS 6-10 (MAY 16-20)
A pattern flip to a high pressure ridge dominating the eastern US means overall drier with a warming trend, though we’ll have to watch for high pressure to the north pushing a boundary southward and making at least coastal areas cooler at some point mid to late period.

DAYS 11-15 (MAY 21-25)
Pattern will likely favor a nearby boundary and this opens the door for frequent passing disturbances bringing episodes of wet weather, as well as temperatures ups/downs.

7:32AM

DAYS 1-5 (MAY 10-14)
Upper level low pressure continues to spin over the region but starts to elongate and eventually slips off to the east through Friday. Another upper low and associated surface system will impact the weather this weekend. There is some question as to how far north the resulting storm will come and that will determine timing, duration, and magnitude of rainfall, something to fine-tune in the next 2 days.
TODAY: Partly sunny to mostly cloudy. Isolated showers mainly afternoon. Highs 56-63. Wind N 5-15 MPH.
TONIGHT: Variably cloudy. Lows 39-45. Wind N 5-15 MPH.
THURSDAY: Mostly cloudy. Isolated showers possible. Highs 56-63. Wind N to NE 5-15 MPH.
FRIDAY: Variably cloudy. Isolated to scattered showers mainly AM. Lows 40-47. Highs 56-63.
SATURDAY: AM sun, PM clouds, chance of rain late. Lows 42-49. Highs 56-63.
SUNDAY – MOTHERS DAY: Cloudy. Rain likely. Lows 38-45. Highs 45-52.

DAYS 6-10 (MAY 15-19)
Lingering cool air and a risk of showers May 15 as upper level low pressure hangs on, then a transition to warmer and mainly dry weather follows as the pattern becomes more progressive.

DAYS 11-15 (MAY 20-24)
Starting out dry and seasonable to warm, then wet weather returning later in the period.

7:32AM

DAYS 1-5 (MAY 9-13)
Upper level low pressure will continue dominate the weather during the next few days. Again though we will be given examples of how periods of nicer weather can also take place during this time, this morning being one of them with some sunshine before clouds dominate. We may also see a little more sunshine Wednesday and perhaps Friday, with Thursday being the “least fair” day of this stretch. Confidence drops for Saturday due to uncertainty on development and movement of a possible coastal storm, but going with a drier forecast for now in between systems as the current upper low moves out and another one approaches.
TODAY: Partly sunny to mostly cloudy. Scattered showers this afternoon. Highs 54-61. Wind light SW to S becoming variable, with sea breezes developing.
TONIGHT: Variably cloudy. Isolated showers early. Lows 37-44. Wind NW 5-15 MPH.
WEDNESDAY: Partly sunny. Isolated showers mainly afternoon. Highs 56-63. Wind N 5-15 MPH.
THURSDAY: Mostly cloudy. Scattered to general showers mainly PM. Lows 40-47. Highs 56-63.
FRIDAY: Variably cloudy. Isolated to scattered showers mainly AM. Lows 40-47. Highs 56-63.
SATURDAY: Partly sunny. Lows 42-49. Highs 58-65.

DAYS 6-10 (MAY 14-18)
Another upper low may bring a rain risk May 14 into May 15 which could even end as a mix in some areas on May 15. The remainder of the period should be similar to the weather we are currently experiencing as upper level low pressure lingers over the region.

DAYS 11-15 (MAY 19-23)
Still looking at a possible transition to dry and warmer weather during this period.

7:33AM

DAYS 1-5 (MAY 8-12)
Upper level low pressure will dominate the weather during the next several days. Its orientation is shifting so after our fairly mild weekend it will be cooler for this week, though it still will not result in any all-day rain, just episodes of showers. The low will start to elongate and drift away toward the end of the week.
TODAY: Variably cloudy. Scattered showers eastern MA early to mid morning. Isolated to scattered showers anywhere midday through afternoon. Highs 55-62. Wind W 5-15 MPH, higher gusts.
TONIGHT: Variably cloudy. Isolated showers early. Lows 37-44. Wind W 5-15 MPH.
TUESDAY: Partly sunny to mostly cloudy. Scattered to general showers afternoon. Highs 54-61. Wind SW 5-15 MPH, higher gusts.
TUESDAY NIGHT: Variably cloudy. Isolated showers early. Lows 37-44. Wind NW 5-15 MPH.
WEDNESDAY: Partly sunny. Isolated showers mainly afternoon. Highs 56-63. Wind N 5-15 MPH.
THURSDAY: Mostly cloudy. Scattered to general showers. Lows 40-47. Highs 56-63.
FRIDAY: Variably cloudy. Isolated to scattered showers. Lows 40-47. Highs 56-63.

DAYS 6-10 (MAY 13-17)
Another upper low moves into the region on the weekend of May 13-14 and brings a risk of rain, though there is some chance this surface feature stays far enough south for a miss. This should be followed by a pattern similar to the one going on this week.

DAYS 11-15 (MAY 18-22)
Still looking at a possible transition to dry and warmer weather during this period.

11:30AM

DAYS 1-5 (MAY 7-11)
Not much to change in today’s update. Upper level low pressure will continue spin over the northeastern USA for the entirety of this period, which is an unsettled pattern but not full of wash-out days. As always, timing individual periods of wet weather is a little difficult but updates will continue to process of focusing the forecast especially through the first 2 days.
TODAY: Partly to mostly sunny through early afternoon. Partly to mostly cloudy mid afternoon on. Showers likely over Cape Cod and a few scattered showers mainly west of Boston late in the day. Highs 58-66, coolest South Coast. Wind S 5-15 MPH with higher gusts.
TONIGHT: Mostly cloudy. Scattered showers. Lows 45-52. Wind SW under 10 MPH.
MONDAY: Variably cloudy. Isolated to scattered showers. Highs 55-62. Wind W 5-15 MPH.
TUESDAY THROUGH THURSDAY: Variably cloudy. Daily risk of showers, highest risk Tuesday PM and Thursday AM based on current timing. Lows 45-52. Highs 56-63.

DAYS 6-10 (MAY 12-16)
Elongation of the upper low early in the period and then another slightly more progressive upper low later in the period will likely keep it on the unsettled side with temperatures near to mostly below normal for this period.

DAYS 11-15 (MAY 17-21)
Continued somewhat lower than average confidence on this outlook but still feeling that a milder/drier stretch of weather may get underway during these days, at least toward the end.

8:54AM

DAYS 1-5 (MAY 6-10)
Upper level low pressure will spin over the northeastern USA for the entirety of this period, but despite some weather apps telling you that we were in for days upon days of rain, we are not. We had some significant rainfall on Friday as the surface system associated with the upper low moved across the region, and now we will see varying weather during this period, caused by a blocking pattern – when weather systems move very little or stay nearly stationary for a period of time. But even when you are in the low pressure region of one of these patterns, you can still get episodes of good weather when areas of drier air move into your region. In this case, the low pressure area being centered a little more to the west this weekend will allow it to be fairly mild, and part of the weekend will feature some sun too. A shift east and southeast of the upper low early next week will result in cooler weather, but still unsettled with several opportunities for showers. To time these opportunities is difficult, so will leave it as a more general idea and fine-tune with each update.
TODAY: Overcast through midday with areas of fog dissipating. Mostly cloudy afternoon with best chance of intervals of sunshine southwest of Boston. Steadiest rain over southeastern MA into mid morning, otherwise episodes of scattered showers and brief downpours possible anywhere, but favoring RI, eastern MA, and southeastern NH. Highs 58-63 South Coast, 64-69 elsewhere. Wind S 5-15 MPH with higher gusts.
TONIGHT: Variably cloudy. Passing showers possible. Lows 47-54. Wind S 5-15 MPH
SUNDAY: Partly to mostly sunny morning through early afternoon. Partly to mostly cloudy mid afternoon on. Showers likely over Cape Cod and a few scattered showers mainly west of Boston late in the day. Highs 58-66, coolest South Coast. Wind S 5-15 MPH with higher gusts.
SUNDAY NIGHT: Mostly cloudy. Scattered showers. Lows 45-52. Wind SW under 10 MPH.
MONDAY: Variably cloudy. Isolated to scattered showers. Highs 55-62. Wind W 5-15 MPH.
TUESDAY & WEDNESDAY: Variably cloudy. Daily risk of showers. Lows 45-52. Highs 55-62.

DAYS 6-10 (MAY 11-15)
Elongation of the upper low early in the period and then another slightly more progressive upper low later in the period will likely keep it on the unsettled side with temperatures near to mostly below normal for this period.

DAYS 11-15 (MAY 16-20)
Low confidence forecast but looks like a transition to a more progressive pattern may try to get underway meaning weather systems move along and some warmer air will also return.

7:22AM

DAYS 1-5 (MAY 5-9)
Low pressure tracks west of New England today and tonight sending wet weather into the region, some of it in the form of heavy downpours. Then for the weekend a large upper level low pressure area will swirl over the Northeast with clouds dominant, occasional but not continuous wet weather, but fairly mild air. The upper low will continue to impact the region early next week though it will be cooler.
TODAY: Overcast. Spotty light rain through midday. Widespread rain, some heavy, and a slight chance of thunderstorms, pushing southwest to northeast across the region this afternoon. Highs 51-58. Wind SE to E 5-15 MPH with higher gusts especially late in the day.
TONIGHT: Cloudy. Numerous showers and a chance of thunderstorms early, then scattered showers, though more numerous showers/downpours possible over far southeastern MA. Temperatures steady or rising slightly. Wind SE 10-20 MPH with higher gusts, shifting to S.
SATURDAY: Cloudy morning with episodes of showers, heaviest over southeastern MA. Mostly cloudy to partly sunny afternoon with a slight chance of showers through mid afternoon then a better chance of showers again late day. Highs 62-69. Wind S 10-20 MPH with higher gusts.
SATURDAY NIGHT: Mostly cloudy. Slight chance of showers. Lows 52-59. Wind S 5-15 MPH.
SUNDAY: Variably cloudy. Slight chance of showers through early afternoon then increasing chance of showers later in the day. Highs 60-67. Wind S 5-15 MPH with higher gusts.
MONDAY AND TUESDAY: Variably cloudy. Episodes of scattered showers. Lows 46-52. Highs 53-60.

DAYS 6-10 (MAY 10-14)
Upper level low pressure will continue to spin across the region for pretty much the entire period but with cooler than normal temperatures and a daily threat of showers, but may relax its grip toward the end of the period.

DAYS 11-15 (MAY 15-19)
Still a low confidence forecast here, but the departure of one upper low may be followed by the arrival of another with more unsettled weather being dominant.

7:26AM

DAYS 1-5 (MAY 4-8)
A small area of high pressure allows a nice spring day today though the sun which starts out bright will fade during the day as high cloudiness moves in well in advance of a storm system heading this way. That storm will move in on Friday with wet weather developing. Then, upper level low pressure will hang around during the weekend and the start of next week with unsettled weather.
TODAY: Sunny start, then increasing clouds. Highs 58-66. Wind light variable becoming SE up to 10 MPH.
TONIGHT: Thickening overcast. Lows 44-53. Wind light SE.
FRIDAY: Overcast. Rain arrives west to east, may be heavy at times in the afternoon including a slight chance of thunderstorms. Highs 54-62. Wind SE 5-15 MPH except 10-20 MPH South Coast, higher gusts late-day.
FRIDAY NIGHT: Mainly cloudy. Occasional showers. Lows 47-55. Wind SE to S 5-15 MPH with higher gusts.
SATURDAY: Mostly cloudy to partly sunny. Chance of showers. Highs 56-62 South Coast, 62-70 elsewhere. Wind SE to S 5-15 MPH.
SUNDAY: Mostly cloudy to partly sunny. Chance of showers. Lows 45-53. Highs 57-65.
MONDAY: Mostly cloudy. Chance of showers/drizzle. Lows 44-50. Highs 50-58.

DAYS 6-10 (MAY 9-13)
Upper level low pressure may be very stubborn to move with additional unsettled weather and temperatures running on the cooler side of normal.

DAYS 11-15 (MAY 14-18)
Blocking pattern may break down or shift to allow somewhat milder and drier weather, but low confidence in this outlook.

7:29AM

DAYS 1-5 (MAY 3-7)
A cool pool at upper levels triggers diurnal clouds today. An approaching storm sends its clouds into the region Thursday but they will be of the high, thin variety and allow the sun to shine for a portion of the day first. Then a slow moving storm brings rain into the region during Friday. A large upper level low pressure area will spin over the Northeast this weekend with unsettled weather, although it will not rain the entire time.
TODAY: Sun early then lots of passing clouds. Highs 58-66. Wind NW 10-20 MPH.
TONIGHT: Lots of clouds early, then clearing. Lows 35-45, coldest interior valleys. Wind NW diminishing to under 10 MPH.
THURSDAY: Sunny start, then increasing clouds. Highs 58-66. Wind light variable becoming SE up to 10 MPH.
FRIDAY: Overcast. Rain arrives west to east, may be heavy at times. Lows 45-53. Highs 53-60.
SATURDAY: Mostly cloudy to partly sunny. Showers likely. Lows 47-55. Highs 60-68.
SUNDAY: Mostly cloudy to partly sunny. Chance of showers. Lows 45-53. Highs 57-65.

DAYS 6-10 (MAY 8-12)
A blocking pattern will place upper level low pressure over the region with more unsettled weather and below normal temperatures.

DAYS 11-15 (MAY 13-17)
A little drier and milder weather develops during this period as a more zonal flow is expected.

7:38AM

DAYS 1-5 (MAY 2-6)
A “cold front” pushes through today. I put it in quotes because even though it is a cold front by text book definition, it will actually warm up behind it as it is pushing out a warm airmass that was sitting above cooler marine air trapped at the ground in a lot of the region, though some areas south and west of Boston did get to experience the warmer air before the front arrived. A cool pool in the upper atmosphere will drift across the region Wednesday and will at the very least develop some diurnal cloudiness, and perhaps some showers. High pressure will move in providing a gem of a day on Thursday, though sunshine may fade later in the day as high cloudiness moves in ahead of a broad low pressure area. Though the timing of this system is still a little uncertain, it will arrive with wet weather sometime Friday. Its broad associated upper level low will park itself west of New England by Saturday, which will be another unsettled day.
TODAY: Mostly cloudy through early afternoon with areas of drizzle/fog and isolated to scattered showers and thunderstorms. Partly cloudy later in the day with isolated showers. Highs 66-75, coolest Cape Cod. Wind W 10-20 MPH.
TONIGHT: Partly cloudy. Lows 45-53. Wind NW 5-15 MPH.
WEDNESDAY: Partly cloudy. Slight risk of isolated showers. Highs 58-66. Wind NW 10-20 MPH.
THURSDAY: Sunny start, then increasing clouds. Lows 45-53. Highs 60-68.
FRIDAY: Overcast. Periods of rain. Lows 45-53. Highs 53-60.
SATURDAY: Mostly cloudy to partly sunny. Showers likely. Lows 45-53. Highs 58-66.

DAYS 6-10 (MAY 7-11)
Unsettled weather dominates. Frequent periods of showers or rain. Temperatures start the period near normal then cool to below normal.

DAYS 11-15 (MAY 12-16)
A little drier and milder weather develops during this period.

7:43AM

DAYS 1-5 (MAY 1-5)
A warm front struggles across the region today from southwest to northeast, setting up a contrast in temperature. This will be followed by a cold front west to east tonight when a greater chance of showers and possibly a thunderstorm will occur. This exits early Tuesday, which ends up warmer due to a westerly wind. High pressure builds in with fair and cooler weather Wednesday. Low pressure approaches Thursday and brings a solid chance of wet weather by Thursday night and Friday.
TODAY: Mainly cloudy but sunny breaks possible later in the day especially Boston area west and south. Highs 48-56 immediate coast, 57-66 most other areas but may reach 67-72 interior areas west and southwest of Boston late. Wind light variable eventually becoming S.
TONIGHT: Mainly cloudy. Showers and a chance of thunderstorms mainly after 10PM from west to east. Temperatures rise in northeastern areas and only fall slightly to the southwest then remain steady 55-63 overnight. Wind S to SW 10-20 MPH shifting to W.
TUESDAY: Mainly cloudy with a few lingering showers early then partly to mostly sunny. Highs 66-75, coolest Cape Cod. Wind W 10-20 MPH.
WEDNESDAY: Partly cloudy. Lows 45-53. Highs 58-66.
THURSDAY: Increasing clouds. Rain at night. Lows 45-53. Highs 60-68.
FRIDAY: Overcast. Periods of rain. Lows 45-53. Highs 53-60.

DAYS 6-10 (MAY 6-10)
Unsettled weather at times, especially first half of the period. Temperatures near to below normal.

DAYS 11-15 (MAY 11-15)
A period of drier and warmer weather is possible.

7:46AM

DAYS 1-5 (APRIL 30-MAY 4)
High pressure and a cooler air mass is the story for southern New England today, though advancing warm air aloft and some mid level instability may support some showers into western areas this afternoon. Warm front comes across southern New England Monday, followed by a cold front Monday night and early Tuesday, and high pressure Wednesday. The next low pressure area approaches Thursday. The resultant weather expected is broken down in the next several lines.
TODAY: Partly sunny. A few showers possible mainly CT and central MA by mid afternoon. Highs 52-57 coast, 57-62 interior. Wind N 5-15 MPH shifting to E.
TONIGHT: Mainly cloudy. Chance of light rain mainly after midnight. Lows 44-51. Wind light E.
MONDAY: Mainly cloudy. Chance of light rain. Highs 55-60 coast, 60-65 interior. Wind light SE shifting to S 10-20 MPH late.
MONDAY NIGHT: Mostly cloudy. Showers likely. Chance of thunderstorms. Lows 50-55. Wind S 10-20 MPH shifting to W by dawn.
TUESDAY: Partly cloudy. Chance of showers early. Highs 65-70 South Coast, 70-75 elsewhere. Wind W 10-20 MPH.
WEDNESDAY: Mostly sunny. Lows from the middle 40s to lower 50s. Highs from the upper 50s to middle 60s, coolest East Coast.
THURSDAY: Increasing clouds. Lows from the upper 40s to middle 50s. Highs in the 60s.

DAYS 6-10 (MAY 5-9)
Watching for a possible significant rain event somewhere early in the period and a persistent upper low that would keep the weather unsettled through the period.

DAYS 11-15 (MAY 10-14)
Somewhat milder/drier weather expected. Continued low confidence forecast.

10:52AM

DAYS 1-5 (APRIL 29-MAY 3)
As April turns to May, we have a bit of a tricky forecast situation coming. But first, a weekend that will be fairly decent, though will exhibit 2 distinctive feels. Today, a taste of summer. A cold front will come through later and may trigger a shower near the South Coast but otherwise its main impact will be to bring much cooler weather for Sunday. This front will then attempt to come back north as a warm front Monday, but probably won’t fully get through here until Tuesday. So Monday’s forecast is a little tricky. There should be a lot of clouds and some wet weather, and for now I will lean to the cooler side with the front taking its time. The warmer weather should be back by Tuesday, only to be pushed out once again Wednesday as a slightly cooler airmass comes down from Canada.
TODAY: Partly sunny. An isolated shower possible South Coast. Highs 65-73 South Coast, 74-83 elsewhere. Wind W 10-20 MPH.
TONIGHT: Partly cloudy. Lows 45-52. Wind NW 5-15 MPH.
SUNDAY: Partly sunny. Highs 52-57 coast, 57-62 interior. Wind N 5-15 MPH shifting to E.
SUNDAY NIGHT: Mainly cloudy. Chance of light rain after midnight. Lows 44-51. Wind light E.
MONDAY: Mainly cloudy. Chance of light rain. Highs 52-57 coast, 57-62 interior. Wind light SE.
TUESDAY: Partly cloudy. Lows from the upper 40s to middle 50s. Highs from the middle 60s to middle 70s, coolest South Coast.
WEDNESDAY: Mostly sunny. Lows from the middle 40s to lower 50s. Highs from the upper 50s to middle 60s, coolest East Coast.

DAYS 6-10 (MAY 4-8)
Watching for a possible significant rain event somewhere early to mid period and a persistent upper low that would keep the weather unsettled through the period. Much fine-tuning to come.

DAYS 11-15 (MAY 9-13)
Exit of upper low should be folloed by somewhat milder and drier weather, but low confidence forecast at this time.

7:28AM

DAYS 1-5 (APRIL 28-MAY 2)
Many changes, typical of spring, as we get a warm front through today, follow it with a cold front Saturday, and likely repeat the process Monday and Tuesday. The details as always become a little harder to pin down with time so it will be important to follow updates.
TODAY: Cloudy morning with a showers and a few downpours around including the risk of thunder. Sun appears this afternoon. Highs 58-65 South Coast, 66-77 elsewhere. Wind light S this morning, SW to W 10-20 MPH this afternoon.
TONIGHT: Increasing clouds. Lows 53-61. Wind W up to 10 MPH.
SATURDAY: Mostly cloudy through midday with risk of a shower and possibly a thunderstorm, then partly cloudy. Highs 63-71 South Coast, 72-82 elsewhere. Wind W 10-20 MPH.
SATURDAY NIGHT: Variably cloudy. Lows 46-53. Wind NW 5-15 MPH.
SUNDAY: Partly cloudy. Highs 55-62 coast, 62-68 interior. Wind N to NE 5-15 MPH.
MONDAY: Mostly cloudy. Chance of light rain. Lows 48-55. Highs 58-65.
TUESDAY: Partly sunny. Chance of showers early. Lows 50-58. Highs 65-75.

DAYS 6-10 (MAY 3-7)
A significant rain event is possible around the middle of the period. Temperatures variable.

DAYS 11-15 (MAY 8-12)
Still looking at a somewhat active pattern with up and down temps and a couple wet weather threats.

7:44AM

DAYS 1-5 (APRIL 27-MAY 1)
Quick and easy. Low pressure spins down and dissipates over the region today. A warm front passes through on Friday, followed by a cold front later Saturday. Between the 2 fronts comes a preview of summer. After the cold front passes, cooler high pressure builds across eastern Canada and noses into New England. But Monday, a warm front is again trying to push through the region, returning clouds and unsettled weather.
TODAY: Mostly cloudy. Areas of fog and drizzle early. Highs 55-61 coast, 61-67 interior. Wind light variable.
TONIGHT: Mostly cloudy. Lows 50-58. Wind SW up to 10 MPH.
FRIDAY: Mostly cloudy through early afternoon with a chance of showers, then decreasing clouds . Highs 62-77, coolest South Coast. Wind S 5-15 MPH shifting to SW 10-20 MPH.
SATURDAY: Partly cloudy. Slight chance of late-day shower/thunderstorm. Lows 52-60. Highs 64-80, coolest South Coast.
SUNDAY: Mostly sunny. Lows 45-52. Highs 55-64, coolest East Coast.
MONDAY: Mostly cloudy. Chance of drizzle or light rain. Lows 45-52. Highs 55-64, coolest coastal areas.

DAYS 6-10 (MAY 2-6)
Episodes of showers, changeable temperatures as several systems pass through.

DAYS 11-15 (MAY 7-11)
Active pattern brings quick changes but no major storms.
