7:34AM

DAYS 1-5 (MAY 9-13)
High pressure hangs on today with dry weather, though not as sunny as yesterday. Low pressure tracks north of the region Friday and its warm front / cold front combo brings unsettled weather, but this moves right along and sets up a fairly nice weekend with great weather Saturday and fair weather holding on Sunday as high pressure forces the first of 2 low pressure areas south of the region. The second low will take advantage of departing high pressure to bring wet/cool weather Monday.
Forecast details…
TODAY: Partly sunny to mostly cloudy. Highs 58-65, cooling back along the coast. Wind light SE.
TONIGHT: Mostly cloudy. Lows 47-54. Wind SE 5-15 MPH.
FRIDAY: Mostly cloudy. Episodes of rain showers. Highs 52-59 coast, 60-67 interior. Wind SE 5-15 MPH shifting to S.
FRIDAY NIGHT: Mostly cloudy. Rain showers and possible thunderstorms evening, ending overnight west to east. Areas of fog. Lows 45-52. Wind W 5-15 MPH.
SATURDAY: Sun and passing clouds. Highs 59-66. Wind W 5-15 MPH and gusty.
SATURDAY NIGHT: Mostly clear. Lows 40-47. Wind light W.
SUNDAY: Variably cloudy. Highs 57-64. Wind light variable becoming SE.
SUNDAY NIGHT: Cloudy. Rain arriving overnight. Lows 41-48. Wind light E.
MONDAY: Overcast. Rain/drizzle likely. Highs 47-54. Wind N to NE 5-15 MPH.

DAYS 6-10 (MAY 14-18)
Low pressure departs slowly to east with upper level low pressure still around for somewhat unstable conditions and a chance of rain showers May 14 into May 15. Mostly dry weather in the May 16-18 period but a cold front may cross sometime late May 16 to May 17 with a few rain showers.

DAYS 11-15 (MAY 19-23)
I remain cautiously optimistic for a drier overall pattern and near to above normal temperatures.

6:58AM

DAYS 1-5 (MAY 8-12)
High pressure moves in today and hangs on well into Thursday with fair weather. Low pressure tracks north of the region Thursday night through Friday bringing a warm front / cold front combo and more unsettled weather. But that won’t be hanging around as another set-up similar to today/Thursday occurs over the weekend, leaving us with the question of how many dry hours we can hang onto for Mother’s Day as the next low pressure area approaches. This low will be further south than Friday’s and will threaten a more widespread rain, but may also be delayed in its arrival, saving most of the day from rain.
Forecast details…
TODAY: Mostly sunny except partly sunny South Coast. Highs 55-62 coast, 62-69 interior. Wind light variable with sea breezes.
TONIGHT: Mostly clear except partly cloudy South Coast. Lows 36-43 interior valleys, 43-50 elsewhere with mildest urban centers. Wind light variable.
THURSDAY: Sunshine followed by increasing cloudiness. Highs 58-65, cooling back along the coast. Wind light SE.
THURSDAY NIGHT: Cloudy. Rain likely north and west of Boston. Rain possible from Boston south. Lows 47-54. Wind SE 5-15 MPH.
FRIDAY: Cloudy. Rain showers likely. Highs 52-59 coast, 60-67 interior. Wind SE 5-15 MPH shifting to S.
FRIDAY NIGHT: Mostly cloudy. Rain showers ending west to east. Areas of fog. Lows 45-52. Wind W 5-15 MPH.
SATURDAY: Early clouds, then mostly sunny. Highs 57-64. Wind W 5-15 MPH and gusty.
SATURDAY NIGHT: Mostly clear. Lows 40-47. Wind light W.
SUNDAY: Increasing clouds. Chance of rain afternoon. Highs 58-65, coolest coast. Wind light variable to SE.

DAYS 6-10 (MAY 13-17)
A broad low pressure area brings wet weather May 13 followed by clearing May 14, then a smaller low pressure system brings a risk of rain showers later May 15 to early May 16. Additional low may have to be watched for May 17 but leaning toward drier at this time. Temperatures near normal overall.

DAYS 11-15 (MAY 18-22)
I am cautiously optimistic for a drier overall pattern and near to above normal temperatures. Still have low confidence this far in advance.

7:00AM

DAYS 1-5 (MAY 7-11)
Not making any significant forecast changes on this update. Quick warm day today but clouds move in and eventually a shower and potential thunderstorm threat as a cold front approaches, then passes through the region tonight. This sets up another nice but cooler day tomorrow. Broad low pressure approaches Thursday, which starts dry and ends wet, and makes Friday another wet day, but it is gone by the start of the weekend when another area of cool high pressure will move in.
Forecast details…
TODAY: Sun followed by clouds. Scattered rain showers and isolated thunderstorms northern and western areas by mid to late afternoon. Highs 55-62 Cape Cod, 63-70 other coastal areas, 70-77 interior. Wind SW 5-15 MPH.
TONIGHT: Mostly to partly cloudy. Scattered rain showers with a risk of thunder southern and eastern areas evening. Lows 50-57. Wind W 5-15 MPH shifting to NW.
WEDNESDAY: Mostly sunny except partly sunny South Coast. Highs 55-62 coast, 62-69 interior. Wind light variable with sea breezes.
WEDNESDAY NIGHT: Mostly clear except partly cloudy South Coast. Lows 36-43 interior valleys, 43-50 elsewhere with mildest urban centers. Wind light variable.
THURSDAY: Increasing cloudiness. Late-day rain west to east. Highs 58-65, cooling back along the coast. Wind light SE.
THURSDAY NIGHT: Cloudy. Rain likely. Lows 47-54. Wind SE 5-15 MPH.
FRIDAY: Cloudy. Periods of rain. Highs 48-55 coast, 55-62 interior. Wind SE 10-20 MPH.
FRIDAY NIGHT: Cloudy. Rain tapering off. Patchy fog and drizzle. Lows 43-50. Wind light variable.
SATURDAY: Early clouds, then mostly sunny. Highs 57-64. Wind W 10-20 MPH and gusty.

DAYS 6-10 (MAY 12-16)
High pressure brings fair weather May 12. Low pressure brings rain May 13. High pressure brings fair weather May 14. A system passing to the north sends clouds and a rain shower threat into the region May 15 into May 16 before clearing.

DAYS 11-15 (MAY 17-21)
The forecast remains low confidence, but one change I am starting to see is that low pressure may evolve away from the region and high pressure closer to this area bringing a greater chance of prolonged fair weather. Still have to figure this out.

6:37AM

DAYS 1-5 (MAY 6-10)
High pressure provides nice weather today and again Wednesday. The only slight interruption to the fair weather will be a cold front that drops through the region from northwest to southeast late Tuesday, which will be the warmest day of the next 5, but may also see a few late day and evening rain showers and a remote risk of thunder. But this also marks a longer period of time than we have seen in a while without being impacted by a low pressure system coming along the jet stream. However, the next system will arrive from the west later in the week. So we are not completely out of the active pattern yet but there will be a bit of a slowing down of the activity during this week.
Forecast details…
TODAY: Clouds give way to sun. Highs 63-70 except 56-63 coast, coolest Cape Cod. Wind N up to 10 MPH becoming variable with sea breezes.
TONIGHT: Mostly clear. Lows 45-52. Wind light W.
TUESDAY: Sun followed by clouds. Scattered rain showers and isolated thunderstorms northern and western areas by mid to late afternoon. Highs 55-62 Cape Cod, 63-70 other coastal areas, 70-77 interior. Wind SW 5-15 MPH.
TUESDAY NIGHT: Mostly to partly cloudy. Scattered rain showers southern and eastern areas evening. Lows 50-57. Wind W 5-15 MPH shifting to NW.
WEDNESDAY: Mostly sunny except partly sunny South Coast. Highs 55-62 coast, 62-69 interior. Wind light variable with sea breezes.
WEDNESDAY NIGHT: Mostly clear except partly cloudy South Coast. Lows 36-43 interior valleys, 43-50 elsewhere with mildest urban centers. Wind light variable.
THURSDAY: Increasing cloudiness. Late-day rain possible. Highs 58-65, cooling back along the coast. Wind light SE.
THURSDAY NIGHT: Cloudy. Rain likely. Lows 47-54. Wind SE 5-15 MPH.
FRIDAY: Cloudy. Periods of rain. Highs 48-55 coast, 55-62 interior. Wind SE 10-20 MPH.

DAYS 6-10 (MAY 11-15)
High pressure moves in for dry weather for the May 11-12 weekend. Low pressure brings a chance of wet weather for May 13 before fair and milder weather returns for the end of the period as high pressure retakes control of the weather.

DAYS 11-15 (MAY 16-20)
This is a low confidence forecast, but a broad low pressure area may result in several unsettled days during this period.

8:31AM

DAYS 1-5 (MAY 5-9)
Low pressure passes south of the region today, a wet day but wettest along and south of I-90, with lighter and more intermittent rain to the north. High pressure moves in for a nice Monday, then sinks to the south and allows a cold front from Canada to approach Tuesday, which may trigger some showers as it passes through during the afternoon and evening, although it will end up being the warmest day of this 5-day period. Another Canadian high moves in for midweek with more excellent weather. The next system will approach later Thursday, increasing the rain chances again, but we’re starting to see longer periods of time between jet stream disturbances as we enter pattern transition.
Forecast details…
TODAY: Cloudy. Periods of rain much of the day southern MA southward and a shorter period of rain favoring late morning to late afternoon northern MA and southern NH. Highs 55-62 except cooler coast. Wind E 5-15 MPH.
TONIGHT: Mostly cloudy with rain ending evening. Clearing overnight. Lows 45-52. Wind N 5-15 MPH.
MONDAY: Lingering clouds southern areas early, otherwise becoming mostly sunny. Highs 63-70 except 56-63 coast, coolest Cape Cod. Wind N up to 10 MPH becoming variable with sea breezes.
MONDAY NIGHT: Partly cloudy. Lows 45-52. Wind light W.
TUESDAY: Partly cloudy. Chance of rain showers southern NH and northern MA by mid to late afternoon. Highs 55-62 Cape Cod, 63-70 other coastal areas, 70-77 interior. Wind SW 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Scattered rain showers ending from northwest to southeast. Lows 50-57. Wind W 5-15 MPH shifting to NW.
WEDNESDAY: Partly to mostly sunny. Highs 55-62 coast, 62-69 interior. Wind light variable with sea breezes.
WEDNESDAY NIGHT: Mostly clear. Lows 36-43 interior valleys, 43-50 elsewhere with mildest urban centers. Wind light variable.
THURSDAY: Increasing cloudiness. Highs 58-65, cooling back along the coast. Wind light SE.

DAYS 6-10 (MAY 10-14)
Wet weather threat from a jet stream disturbance May 10. A cold front may bring a few showers May 12 but much of the May 11-12 weekend looks dry. More fair weather for the end of the period with a warm-up possible by May 14.

DAYS 11-15 (MAY 15-19)
Still uncertainty here… The pattern evolution has several possibilities including a cut-off low somewhere nearby. Feeling however that this may occur further south or even well offshore and we end up in a continued progressive but slightly less active jet stream flow. Systems in this flow my bring showers early and again late in the period.

8:40AM

DAYS 1-5 (MAY 4-8)
A frontal boundary lingering nearby and a passing disturbance keeps rain showers scattered in the region this morning before a little push of high pressure from the north sends drier air into the region this afternoon, not really clearing the sky too much but ending the rain shower threat. Now there remains some bad news / good news regarding this pattern. The bad news is the parade of weather systems continues for now and that sends the next wet weather system toward the region for Sunday, although the most significant rainfall from this wave of low pressure will fall to the south of I-90 (The Mass Pike), while to the north the period of rainfall may be of somewhat shorter duration. And then a bit of a change. High pressure from Canada slides down into the region Monday, which is going to be a very nice spring day. The sinking of high pressure to the south and the approach of a cold front from the northwest may sound like “uh oh here comes more rain” upon first read but it’s actually going to help create a fabulous day for most of the hours of it, the clouds and threat of rain showers probably holding off until at least the very end of the day, if not at night, then progressing northwest to southeast across the area. Another Canadian high pressure area is expected to bring cooler but again fair weather for the end of this period.
Forecast details…
TODAY: Overcast morning with patchy fog and scattered to isolated rain showers diminishing west to east. Mostly cloudy this afternoon but some breaks of sun possible especially northern half of MA and southern NH. Highs 53-60 coast, 61-68 interior. Wind light variable.
TONIGHT: Mostly cloudy. Slight chance of rain favoring areas west and and south of Boston toward dawn. Lows 45-52. Wind N to E up to 10 MPH.
SUNDAY: Cloudy. Periods of rain much of the day southern MA southward and a shorter period of rain favoring late morning to late afternoon northern MA and southern NH. Highs 55-62 except cooler coast. Wind E 5-15 MPH.
SUNDAY NIGHT: Mostly cloudy with rain ending evening. Clearing overnight. Lows 45-52. Wind N 5-15 MPH.
MONDAY: Mostly sunny. Highs 63-70 except 56-63 coast, coolest Cape Cod. Wind N up to 10 MPH becoming variable with sea breezes.
MONDAY NIGHT: Partly cloudy. Lows 45-52. Wind light W.
TUESDAY: Partly cloudy. Highs 55-62 Cape Cod, 63-70 other coastal areas, 70-77 interior. Wind SW 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Scattered rain showers. Lows 50-57. Wind W 5-15 MPH shifting to NW.
WEDNESDAY: Partly to mostly sunny. Highs 55-62 coast, 62-69 interior. Wind light variable with sea breezes.

DAYS 6-10 (MAY 9-13)
We’re seeing a shift to less frequent systems while still having an active pattern. Wet weather threat comes late May 9 and May 10 from a broad low pressure area. A minor system may threaten at the end of the period.

DAYS 11-15 (MAY 14-18)
Feeling the medium range models don’t have a great handle on the pattern evolution. For now I’m on the lookout for a cut off low somewhere but uncertain as to whether it happens at all, and if so, how it impacts our weather. Will re-evaluate this again tomorrow. Initial feeling is that we start this period dry, end it dry, and see some wet weather in between.

7:28AM

DAYS 1-5 (MAY 3-7)
I often profess my contentment with any kind of weather, but I know many of you are tired of hearing about unsettled weather, so I’ll keep this forecast short, although, for you, it’s not all bad news. There are some nicer days starting to show up again in the forecast. But first, another unsettled and cool one today, brief improvement Saturday, downhill again Sunday as another low pressure wave passes by, and then 2 better days to start next week as high pressure settles in and pushes the unsettled weather away to the south.
Forecast details…
TODAY: Cloudy. Areas of fog. Patchy drizzle. Rain showers arrive west to east this afternoon. Highs 47-54. Wind light E to SE.
TONIGHT: Cloudy. Areas of fog. Patchy drizzle evening. Rain showers likely. Slight chance of thunderstorms overnight. Lows 42-49. Wind light variable.
SATURDAY: Mostly cloudy to partly sunny. Rain showers ending west to east early to mid morning. Highs 52-59 coast, 60-67 interior. Wind light variable.
SATURDAY NIGHT: Cloudy. Periods of rain overnight. Lows 45-52. Wind N to E up to 10 MPH.
SUNDAY: Cloudy. Periods of rain. Highs 52-59 except cooler coast. Wind E 5-15 MPH.
SUNDAY NIGHT: Mostly cloudy. Patchy fog. Chance of drizzle. Lows 45-52. Wind N 5-15 MPH.
MONDAY: Partly sunny. Highs 60-67, except 53-60 Cape Cod. Wind NW 5-15 MPH.
MONDAY NIGHT: Partly cloudy. Lows 45-52. Wind light W.
TUESDAY: Partly cloudy. Highs 55-62 Cape Cod, 63-70 other coastal areas, 70-77 interior. Wind SW 5-15 MPH.

DAYS 6-10 (MAY 8-12)
Transitional pattern gets underway here but not exactly sure how it evolves yet. I think this 5-day period may feature a westerly flow and still a couple unsettled weather systems coming through, but on the weak side with limited rainfall and more seasonable temperatures overall. Fine tuning to do…

DAYS 11-15 (MAY 13-17)
Still watching for the potential for a spring block with a cut-off low somewhere and still too much uncertainty on if/when/where to be sure how the weather turns out during this period. Leaning toward unsettled first half, drying second half of period. Much fine tuning to do…

7:30AM

DAYS 1-5 (MAY 2-6)
We’ll spend this entire period on the cool side of a frontal boundary, with waves of low pressure bringing unsettled weather for much of it. Although it won’t rain nearly the entire time, it will often be cloudy. The best chance to sneak in some sunshine is Saturday, and it may improve more significantly by Monday as high pressure pushes in from Canada.
Forecast details…
TODAY: Cloudy. Areas of fog and drizzle. Periods of rain, favoring northern MA and southern NH. Highs 46-53. Wind light NE.
TONIGHT: Cloudy. Areas of fog. Periods of rain/drizzle overnight. Lows 40-47. Wind light NE.
FRIDAY: Cloudy. Areas of fog. Periods of rain/drizzle possible. Highs 47-54. Wind light NE.
FRIDAY NIGHT: Mostly cloudy. Chance of rain evening. Patchy fog. Lows 42-49. Wind light NE to N.
SATURDAY: Variably cloudy. Highs 52-59 coast, 60-67 interior. Wind light NE to N.
SATURDAY NIGHT: Cloudy. Chance of rain. Lows 45-52. Wind N to E 5-15 MPH.

SUNDAY NIGHT: Mostly cloudy. Patchy fog. Chance of drizzle. Lows 45-52. Wind N 5-15 MPH.
MONDAY: Partly sunny. Highs 60-67, cooler Cape Cod. Wind NW 5-15 MPH.

DAYS 6-10 (MAY 7-11)
Unsettled pattern overall but hard to tell which days stand the greatest chance of wet weather at this point. Temperatures trend milder.

DAYS 11-15 (MAY 12-16)
Will have to watch the pattern which may try to evolve into a typical spring block, but that could put SNE in nicer or continued unsettled weather, depending on configuration. Too early to tell.

6:27AM

DAYS 1-5 (MAY 1-5)
May gets underway with a break between wet weather systems today as high pressure has enough influence to keep the region dry, although cloudiness will dominate. A couple more waves of low pressure coming along and passing south of the region will bring periods of wet weather Thursday and Friday. Another one may impact the region sometime over the weekend, with the leaning toward Sunday at this time.
Forecast details…
TODAY: Partial sun at times, but mainly cloudy. Highs 55-62, coolest coast. Wind light variable
WEDNESDAY NIGHT: Cloudy. Chance of light rain/drizzle late evening and overnight. Lows 45-52. Wind light variable to NE.
THURSDAY: Cloudy. Chance of rain/drizzle morning. Temperatures steady 45-52. Wind light NE.
THURSDAY NIGHT: Cloudy. Chance of rain/drizzle overnight. Lows 40-47. Wind light NE.

SATURDAY: Variably cloudy. Highs 52-59 coast, 60-67 interior. Wind light NE to N.
SATURDAY NIGHT: Cloudy. Chance of rain. Lows 45-52. Wind N to E 5-15 MPH.
SUNDAY: Cloudy. Chance of rain. Highs 52-59 except cooler coast. Wind E 10-20 MPH.

DAYS 6-10 (MAY 6-10)
Unsettled pattern overall but hard to tell which days stand the greatest chance of wet weather at this point. Temperatures trend milder.

DAYS 11-15 (MAY 11-15)
Will have to watch the pattern which may try to evolve into a typical spring block, but that could put SNE in nicer or continued unsettled weather, depending on configuration. Too early to tell.

7:14AM

DAYS 1-5 (APRIL 30-MAY 4)
Back to the dominant unsettled weather pattern for the next 5 days with waves of low pressure keeping clouds and occasional wet weather around. We do get breaks, like tomorrow, which will be mostly dry with some sunshine as well, and possibly part of Saturday, which may see stronger high pressure push the wet weather to the south for a time.
Forecast details…
TODAY: Mostly cloudy. Periods of rain morning. Highs 48-55. Wind light variable.
TONIGHT: Partly cloudy. Lows 38-45. Wind light variable.
WEDNESDAY: Partly sunny. Highs 55-62, coolest coast. Wind light variable
WEDNESDAY NIGHT: Cloudy. Chance of light rain/drizzle. Lows 45-52. Wind light variable to NE.
THURSDAY: Cloudy. Chance of rain/drizzle morning. Temperatures steady 45-52. Wind light NE.
THURSDAY NIGHT: Cloudy. Chance of rain/drizzle. Lows 40-47. Wind light NE.
FRIDAY: Cloudy. Chance of rain/drizzle. Highs 45-55. Wind light NE.
FRIDAY NIGHT: Mostly cloudy. Chance of rain evening. Patchy fog. Lows 42-49. Wind light NE to N.
SATURDAY: Variably cloudy. Chance of rain showers. Highs 53-60. Wind N 5-15 MPH.

DAYS 6-10 (MAY 5-9)
Unsettled pattern overall but hard to tell which days stand the greatest chance of wet weather at this point. Temperatures start out below normal then trend milder.

DAYS 11-15 (MAY 10-14)
Another boundary-to-the south, cooler and somewhat unsettled period is possible here. Low confidence forecast. The pattern can break at any time as model guidance tends to not see that coming.

6:40AM

DAYS 1-5 (APRIL 29-MAY 3)
Today will be the nicest day of the next 5, with high pressure in control, but in the pattern we are in, it won’t last, with clouds already arriving later in the day, and wet weather tonight into Tuesday morning, as a small area of low pressure crosses the region west to east. A small bubble of high pressure brings some clearing Tuesday night into early Wednesday as May begins, but we’re back in the dank tank again later Wednesday through Friday as a frontal boundary sits to the south and waves of low pressure ripple along it, keep us cool and damp.
Forecast details…
TODAY: Sunny, fading behind high clouds later. Highs 55-60 coast, 60-65 interior. Wind NW 5-15 MPH becoming light variable with sea breezes.
TONIGHT: Clouding over evening. Cloudy overnight with a chance of rain. Lows 40-47. Wind light variable.
TUESDAY: Cloudy. Chance of rain morning. Highs 48-55. Wind E 5-15 MPH.
TUESDAY NIGHT: Partly cloudy. Lows 38-45. Wind light NE.
WEDNESDAY: Partly sunny morning. Mostly cloudy afternoon. Chance of light rain late. Highs 55-62, coolest South Coast. Wind S 5-15 MPH.
WEDNESDAY NIGHT: Cloudy. Chance of light rain/drizzle. Lows 45-52. Wind light variable to NE.
THURSDAY: Cloudy. Chance of rain/drizzle. Highs 48-55. Wind light NE.
THURSDAY NIGHT: Cloudy. Chance of rain/drizzle. Lows 40-47. Wind light NE.
FRIDAY: Cloudy. Chance of rain/drizzle. Highs 48-55. Wind light NE.

DAYS 6-10 (MAY 4-8)
High pressure may sneak in for a nice May 4 before low pressure brings more wet weather for May 5. Clearing and a quick cool shot behind that for May 6 and a warming trend with some cloudiness at times for May 7-8, eventually a risk of rain showers by May 8.

DAYS 11-15 (MAY 9-13)
Another boundary-to-the south, cooler and somewhat unsettled period is possible here. Low confidence at this time.

7:27AM

DAYS 1-5 (APRIL 28-MAY 2)
Weak low pressure moves rapidly across the region today, with its track suppressed slightly to the south which will limit rainfall in areas north of the Mass Pike, although to the south it won’t be too significant a rain event either. A similar system comes along with the rain timed for the first 12 hours of Tuesday. High pressure tries to build in for a break on May 1 but the boundary nearby again by the end of the period means additional risk of cool and unsettled weather.
Forecast details…
TODAY: Clouding over. Rain arrives west to east midday through afternoon. Highs 50-57. Wind light variable.
TONIGHT: Cloudy evening with rain ending west to east. Clearing overnight. Lows 35-42. Patchy frost. Wind variable 5-15 MPH becoming N.
MONDAY: Sunny. Highs 55-60 coast, 60-65 interior. Wind NW 5-15 MPH becoming light variable with sea breezes.
MONDAY NIGHT: Clouding over evening. Cloudy overnight with a chance of rain. Lows 40-47. Wind light variable.
TUESDAY: Cloudy. Chance of rain morning. Highs 48-55. Wind E 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Lows 40-47. Wind light NE.
WEDNESDAY: Partly sunny. Highs 55-62, coolest South Coast. Wind S 5-15 MPH.
WEDNESDAY NIGHT: Mostly cloudy. Lows 45-52. Wind light variable.
THURSDAY: Cloudy. Chance of rain. Highs 48-55. Wind light NE.

DAYS 6-10 (MAY 3-7)
Wave of low pressure passes just to the south with a wet/cool day possible May 3 then low pressure departs for a dry but cooler May 4-5 weekend. More wet/cool weather possible about May 6 before it warms up a little at the end of the period.

DAYS 11-15 (MAY 8-12)
Overall pattern doesn’t change much, temperatures cooler than average overall with a risk of a few episodes of wet weather.

2:16AM

DAYS 1-5 (APRIL 27-MAY 1)
In the pre-dawn hours of today, numerous rain showers and embedded thunderstorms will be tapering off from southwest to northeast, and then
low pressure departs today, leaving behind blustery conditions with lots of clouds and a slight risk of a passing instability rain shower. Another low pressure area races out of the Great Lakes and across southern New England by late Sunday with some generally light rainfall, but the air may be cold enough toward the end of the event to cause the precipitation to mix with snow northwest of Boston before ending. High pressure moves in for the one and only fair weather day of this 5-day period on Monday, which can only mean unsettled weather returns as a frontal boundary sets up shop in the region Tuesday and Wednesday to end April and begin May.
Forecast details…
TODAY: Mostly cloudy. Isolated rain showers. Highs 50-57. Wind SW 10-20 MPH, gusting as high as 30 MPH.
TONIGHT: Clearing evening. Increasing clouds overnight. Lows 38-45. Wind W 10-20 MPH early, diminishing thereafter.
SUNDAY: Thickening overcast. Rain arrives west to east midday through afternoon. Highs 50-57. Wind light variable.
SUNDAY NIGHT: Cloudy evening with rain, may mix with snow north and west of Boston before ending. Clearing overnight. Lows 35-42. Wind variable 5-15 MPH becoming N.
MONDAY: Sunny. Highs 55-60 coast, 60-65 interior. Wind NW 5-15 MPH becoming light variable with sea breezes.
MONDAY NIGHT: Increasing clouds. Lows 40-47. Wind light variable.
TUESDAY: Cloudy. Chance of rain. Highs 48-55. Wind E 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Lows 40-47. Wind light NE.
WEDNESDAY: Mostly cloudy. Chance of rain. Highs 48-55. Wind NE 5-15 MPH.

DAYS 6-10 (MAY 2-6)
The boundary between Canadian chill and southeastern US warmth will be nearby early period with cool/damp weather, then low pressure may get just east of the region and pull down some unseasonably chilly air for the May 4-6 period.

DAYS 11-15 (MAY 7-11)
Some temperature recovery is likely but additional unsettled weather is also expected as the overall pattern doesn’t change that much.

9:02AM

DAYS 1-5 (APRIL 26-30)
The final 5 days of April, a month that has been frequently unsettled but mild, will continue the unsettled pattern but start to tilt the temperature scale to a lower level as we see cooler weather overall. The unsettled weather will be here today in the form of warm frontal rain morning and midday and cold frontal showers and possible thunderstorms later today and especially tonight. As low pressure intensifies while moving into eastern Canada, the back side will bring blustery weather for Saturday with a gusty wind, cool air, and although most wet weather will be gone pre-dawn, there still may be a passing shower triggered by cold air aloft. Often times after a day like that, high pressure would settle in for nice weather the next day, but not this time. Another, albeit smaller, low pressure area will come racing along for more unsettled weather Sunday, and it may end up cold enough Sunday night before the precipitation exits that it may end up mixed with some frozen stuff in areas north and west of Boston, especially higher elevations. This will then lead to the only really nice day in the 5-day forecast period, Monday, which will feature plenty of sun which will feel nice even though the air will be on the cool side. A warm front will be moving in by Tuesday with more clouds and potential wet weather.
Forecast details…
TODAY: Cloudy. Periods of rain morning and midday. Isolated to scattered rain showers afternoon. Highs 48-55. Wind light SE.
TONIGHT: Cloudy. Rain showers likely. Possible thunder. Temperatures rise to 53-60. Wind S 5-15 MPH, higher gusts.
SATURDAY: Mostly cloudy to partly sunny. Isolated rain showers. Temperatures steady 53-60. Wind W to NW 10-20 MPH, higher gusts possible.
SATURDAY NIGHT: Partly cloudy. Lows 42-49. Wind NW 10-20 MPH, diminishing.
SUNDAY: Clouding over. Rain likely from mid afternoon on. Highs 55-62. Wind variable 5-15 MPH becoming SE.

DAYS 1-5 (APRIL 25-29)
High pressure brings great April weather today with mild temperatures except for the typical cooler coastal areas due to a sea breeze. Unsettled weather returns during Friday as a low pressure area approaches from the west, bringing a warm front through during the morning and midday followed by a cold front during the night and early Saturday. The upper level trough driving this system looks like it may be in no hurry to get out of here, prolonging showery weather well into Saturday, along with gusty wind and chilly air. And just as that system finally exits, another will arrive on its heals Sunday, although that particular disturbance will be smaller and may get pushed somewhat to the south, so the coverage of rainfall may be less. High pressure returns with more nice weather by Monday.
