Tuesday Forecast

7:29AM

DAYS 1-5 (MARCH 31-APRIL 4)
A blocking pattern will continue as we end March and begin April. First it allows some drier weather the next couple days. Next it will force low pressure initially south of the region as it move eastward, then capturing it and causing a large loop in its track, bringing wet weather back for a time later Thursday to early Friday. Dry weather will be back for the remainder of Friday to Saturday as the low pulls away.
TODAY: Partly sunny. A rain or snow shower near the South Coast early. Highs 42-49. Wind N 5-15 MPH.
TONIGHT: Variably cloudy. Lows 33-40. Wind N 5-15 MPH.
WEDNESDAY: Mostly cloudy. Highs 43-50. Wind N 10-20 MPH.
WEDNESDAY NIGHT: Mostly cloudy. Lows 38-45. Wind NE 10-20 MPH.
THURSDAY: Mostly cloudy. Chance of rain, mainly afternoon and favoring eastern coastal areas. Highs 43-50. Wind NE 10-20 MPH.
THURSDAY NIGHT: Mostly cloudy. Periods of rain. Lows 36-43. Wind NE 5-15 MPH.
FRIDAY: Mostly cloudy with a chance of rain early, then partly sunny. Highs 46-53. Wind N 5-15 MPH.
FRIDAY NIGHT: Variably cloudy. Lows 35-42. Wind N 5-15 MPH.
SATURDAY: Partly sunny. Highs 48-55. Wind NW 10-20 MPH.

DAYS 6-10 (APRIL 5-9)
Milder April 5, a late-day rain shower possible. Cooler thereafter with additional unsettled weather possible April 6-8 then dry weather at the end of the period.

DAYS 11-15 (APRIL 10-14)
Not high confidence but blocking may weaken. This would be a mostly dry pattern with a couple brief and minor unsettled weather events, starting cool then moderating.

Monday Forecast

7:34AM

DAYS 1-5 (MARCH 30-APRIL 3)
A blocking pattern (high pressure eastern Canada, upper level low pressure over the US Northeast, will remain in place, keeping us in a cool and unsettled regime. There are no significant changes to yesterday’s discussion so just going to update the forecast below.
TODAY: Mostly cloudy. Areas of drizzle and fog this morning. Scattered rain showers, favoring mid to late afternoon. Highs 46-53. Wind N 5-15 MPH.
TONIGHT: Mostly cloudy. Scattered rain showers evening. Scattered rain or snow showers overnight. Lows 32-39. Wind N 5-15 MPH.
TUESDAY: Mostly cloudy to partly sunny. Scattered rain or snow showers favoring early morning. Highs 42-49. Wind N 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Lows 33-40. Wind N 5-15 MPH.
WEDNESDAY: Mostly cloudy. Highs 43-50. Wind N 10-20 MPH.

FRIDAY: Partly sunny. Highs 46-53. Wind N 5-15 MPH.

DAYS 6-10 (APRIL 4-8)
Blocking weakens briefly then reloads. It lets things shuffle a bit with dry, cool weather then a brief warm up April 4-5 before cool/unsettled weather chances increase again mid to late period.

DAYS 11-15 (APRIL 9-13)
Leaning toward cooler than average but drier than average weather overall for this 5-day period with a strong enough blocking pattern to keep a lot of the storminess to the south and east of the region.

Sunday Forecast

8:19AM

DAYS 1-5 (MARCH 29-APRIL 2)
An early spring blocking pattern will keep our pattern cool and unsettled during this 5-day period, as is quite evident today – a wet and cool day. Upper level low pressure will traverse the region Monday into Tuesday but slow down as high pressure builds over eastern Canada. Another surface low will travel eastward and pass south of the region on by Wednesday but will be captured by the upper low and do a loop out over the ocean to the east of New England, probably enough to throw some wet weather back into the region sometime Thursday.
TODAY: Overcast. Periods of rain. Areas of fog and drizzle. Highs 40-47. Wind E 5-15 MPH, strongest along the coast with higher gusts.
TONIGHT: Cloudy. Periods of rain evening. Rain showers likely overnight. Slight chance of thunderstorms. Lows 38-45. Wind E 10-20 MPH, a few higher gusts especially coastal areas and higher elevations.
MONDAY: Mostly cloudy. Scattered rain showers, favoring mid to late afternoon. Highs 46-53. Wind N 5-15 MPH.
MONDAY NIGHT: Mostly cloudy. Scattered rain showers evening. Scattered rain or snow showers overnight. Lows 32-39. Wind N 5-15 MPH.
TUESDAY: Mostly cloudy to partly sunny. Scattered rain or snow showers favoring the morning. Highs 42-49. Wind N 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Lows 33-40. Wind N 5-15 MPH.
WEDNESDAY: Mostly cloudy. Highs 43-50. Wind N 10-20 MPH.
WEDNESDAY NIGHT: Mostly cloudy. Lows 38-45. Wind NE 10-20 MPH.
THURSDAY: Mostly cloudy. Chance of rain. Highs 43-50. Wind NE 10-20 MPH.

DAYS 6-10 (APRIL 3-7)
Blocking pattern temporarily weakens with a cooler, drier northwesterly flow April 3-4 followed by moderating temperatures April 5 before the block strengthens and cooler and unsettled weather chances increase again later in the period.

DAYS 11-15 (APRIL 8-12)
Leaning toward cooler than average but drier than average weather overall for this 5-day period with a strong enough blocking pattern to keep a lot of the storminess to the south and east of the region.

Saturday Forecast

10:28AM

DAYS 1-5 (MARCH 28-APRIL 1)
Over the next several days, after this morning’s sunny start, any sun we see will be a bonus, as we head into an unsettled weather pattern. This start as broad low pressure moves into the Great Lakes but its warm front extending eastward from it, south of New England, never quite makes it through, and is the focus for a new low to form, which will pass just south of the region Sunday evening, keeping us on the chilly side of this system, but enough instability aloft may trigger some elevated convection and result in a few thundestorms. This system will produce a fair amount of needed rainfall. We’ve been quite dry in 2020 to date and a recent event along with this event will eliminate some of that deficit. Once the rain-producing part of this system has departed offshore, we’ll be stuck under upper level low pressure for the days following. Earlier it looked like another broad low would approach on April 1, but today I’m leaning a little more toward the upper low being more dominant and actually deflecting the moisture from that storm to the south, while keeping our area unsettled with lots of clouds and precipitation of a showery nature, and I say precipitation because some of those showers may end up in the form of snow once we get to Tuesday morning, as marginally cold enough air will be in place.
TODAY: Increasing clouds. Highs 50-57, coolest coastal areas. Wind SE under 10 MPH.
TONIGHT: Thickening overcast. Rain arrives late evening and overnight southwest to northeast. Lows 37-44. Wind SE 5-15 MPH.
SUNDAY: Overcast. Periods of rain. Highs 40-47. Wind E 5-15 MPH, strongest along the coast with higher gusts.
SUNDAY NIGHT: Cloudy. Periods of rain evening. Rain showers likely overnight. Slight chance of thunderstorms. Lows 38-45. Wind E 10-20 MPH, a few higher gusts especially coastal areas and higher elevations.
MONDAY: Mostly cloudy. Scattered rain showers, favoring late morning and afternoon. Highs 46-53. Wind N 5-15 MPH.
MONDAY NIGHT: Mostly cloudy. Scattered rain showers evening. Scattered rain or snow showers overnight. Lows 32-39. Wind N 5-15 MPH.
TUESDAY: Mostly cloudy to partly sunny. Scattered rain or snow showers favoring the morning. Highs 42-49. Wind N 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Lows 33-40. Wind N 5-15 MPH.
WEDNESDAY: Mostly cloudy. Highs 43-50. Wind N 10-20 MPH.

DAYS 6-10 (APRIL 2-6)
Overall pattern features a block in the atmosphere, high pressure eastern Canada and low pressure northeastern US, which is a cooler than average and unsettled pattern. Details to be worked out as the days draw closer.

DAYS 11-15 (APRIL 7-11)
May be tough to shake the pattern in place for a while, which is typical of springtime, but also guidance does not do a great job all the time so the forecast here is low confidence, leaning toward cooler than average and somewhat unsettled.

Friday Forecast

7:28AM

DAYS 1-5 (MARCH 27-31)
Down the home stretch of March we come, a month that weather-wise was more like a lamb than a lion, although we’ll get a little bit of the lion’s roar before it’s over. But first, as a small storm system passes south of the region early today, many locations start with some grey sky, and even some wet weather near the South Coast, but sun will return and the breeze will pick up, though it will be milder than yesterday for most because it will be a land breeze and not a breeze off the chilly ocean like we had yesterday. The weekend starts off nice with sun giving way to clouds on Saturday, then takes a turn as low pressure heads through the Great Lakes then redevelops on its warm front just south of New England during Sunday. With high pressure holding on in eastern Canada, this set-up is cool and wet for southeastern New England, so get ready for a chilly/wet Sunday. Monday will remain somewhat unsettled as what was the original low from this system will have to come across the region as a weakening trough of low pressure (not an atypical occurrence for a low that was detoured by Canadian high pressure). By Tuesday, a bubble of this high will extended down and end the month of March on a dry but cool note, though how much sun wet see that day remains to be seen.
TODAY: Mostly cloudy start including areas of rain near the South Coast, then sun returning northwest to southeast. Highs 50-57 Cape Cod, 55-62 elsewhere. Wind NW 5-15 MPH, gusting 20-25 MPH.
TONIGHT: Mostly clear. Lows 30-37. Wind N up to 10 MPH.
SATURDAY: Sun then increasing high clouds. Highs 51-58, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.
SATURDAY NIGHT: Cloudy. Mix/rain possible overnight. Lows 32-39. Wind E 5-15 MPH.
SUNDAY: Cloudy. Periods of rain. Highs 40-47. Wind E 10-20 MPH, strongest coastal areas.
SUNDAY NIGHT: Cloudy. Rain tapering to showers/drizzle. Areas of fog. Lows 41-48. Wind NE 5-15 MPH, higher gusts.
MONDAY: Mostly cloudy. Chance of rain showers. Highs 43-50. Wind N 5-15 MPH, higher gusts.
MONDAY NIGHT: Variably cloudy. Lows 33-40. Wind N 5-15 MPH.
TUESDAY: Partly sunny. Highs 45-52. Wind N 5-15 MPH.

DAYS 6-10 (APRIL 1-5)
Broad low pressure approaches and may impact the region April 1 into April 2 but its level of impact is uncertain. High pressure in eastern Canada may be strong enough to force a lot of it south of New England. If it is close enough for impact there may be some mix/snow involved for a portion of the time. Drier weather and on the cool side April 3-4, followed by a warm-up at the end of the period.

DAYS 11-15 (APRIL 6-10)
A return to near to below normal temperatures with unsettled weather favoring the early to mid portion of this period.

Thursday Forecast

7:30AM

DAYS 1-5 (MARCH 26-30)
High pressure brings fair weather today. A trough of low pressure passes through tonight and early Friday, moisture-starved, with only a threat of a little rainfall closer to the South Coast, before another high moves in with more dry weather later Friday and Saturday. A broad and more moisture-laden low pressure area will bring wet weather to the region Sunday, with upper level low pressure hanging around behind it Monday, keeping the weather somewhat unsettled with a threat of additional rain showers. We’ll have to watch the start of the precipitation for this system late Saturday night, if it’s in early enough, as temperatures will be marginally cold enough for mix/snow for a brief time in some areas.
TODAY: Mostly sunny. Highs 48-55. Wind variable up to 10 MPH with coastal sea breezes.
TONIGHT: Increasing clouds. Lows 40-47. Wind SE up to 10 MPH.
FRIDAY: Mostly cloudy morning with some rain possible near the South Coast, then clearing. Highs 50-57. Wind NW 5-15 MPH.
FRIDAY NIGHT: Mostly clear. Lows 30-37. Wind N up to 10 MPH.
SATURDAY: Sun then increasing high clouds. Highs 51-58, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.
SATURDAY NIGHT: Cloudy. Mix/rain possible overnight. Lows 32-39. Wind E 5-15 MPH.
SUNDAY: Cloudy. Periods of rain. Highs 48-55. Wind E 10-20 MPH, strongest coastal areas.
SUNDAY NIGHT: Cloudy. Rain tapering to showers/drizzle. Areas of fog. Lows 41-48. Wind NE 5-15 MPH, higher gusts.
MONDAY: Mostly cloudy. Chance of rain showers. Highs 43-50. Wind N 10-20 MPH, higher gusts.

DAYS 6-10 (MARCH 31-APRIL 4)
High pressure brings drier weather March 31. Low pressure approaches then moves through the region later April 1 into April 2 with a threat of rain that may start as snow/mix for some areas. Drier weather follows. Temperatures not far from normal.

DAYS 11-15 (APRIL 5-9)
Precipitation threat with low pressure in vicinity April 5-7. Drier again later in the period. Temperatures near to slightly below normal.

Wednesday Forecast

7:23AM

DAYS 1-5 (MARCH 25-29)
Low pressure passes south of the region today and tonight keeping the rain threat later today mainly in southern MA southward. A break between systems Thursday and the next one Friday will be a disjointed system with one low center passing harmlessly across southeastern Canada with no impact, and a second one passing to the south with maybe a shot at brief rain again over some southern locations. Another break Saturday before the every-other-day low pressure pattern rolls on with a larger one arriving by early Sunday with more unsettled weather. This one will likely be more complex because it may have mix involved at the start if it’s early enough, and with a low center that may travel right over New England, some air mass changes and temperature contrasts would become likely as well. Fine-tuning to come.
TODAY: Becoming cloudy. Afternoon rain favoring areas south of I-90. Highs 40-47. Wind NE 5-15 MPH.
TONIGHT: Cloudy. Any rain ending. Temperatures steady 40-47. Wind E 10-20 MPH, higher gusts.
THURSDAY: Mostly cloudy. Highs 45-52. Wind variable 5-15 MPH.
THURSDAY NIGHT: Mostly cloudy. Lows 40-47. Wind SE 5-15 MPH.
FRIDAY: Mostly cloudy. A period of rain or rain showers possible mainly south of I-90. Highs 47-54. Wind variable 5-15 MPH.
FRIDAY NIGHT: Partly cloudy. Lows 30-37. Wind N 5-15 MPH.
SATURDAY: Mostly cloudy. Highs 43-50. Wind E up to 10 MPH.
SATURDAY NIGHT: Cloudy. Mix/rain possible overnight. Lows 32-39. Wind E 5-15 MPH.
SUNDAY: Mostly cloudy. Rain favoring morning, tapering to rain showers afternoon. Highs 50-57 north, 55-62 south. Wind variable 10-20 MPH.

DAYS 6-10 (MARCH 30-APRIL 3)
Low pressure departs March 30 with a few rain showers but a drier trend. Dry March 31. Next low pressure brings a threat of rain (may start as snow/mix) later April 1 into April 2. Drier weather follows.

DAYS 11-15 (APRIL 4-8)
Cooler/drier April 4. Precipitation threat with low pressure in vicinity April 5-7. Drier again at the end of the period.

Tuesday Forecast

7:27AM

DAYS 1-5 (MARCH 24-28)
Last night’s storm behaved pretty much as expected with most snow falling over interior locations north and west of Boston, some snow elsewhere then mainly rain, some of it heavy, which made a nice dent in the significant precipitation deficit we had for early 2020. Today we get a break between low pressure systems as one departs and the other starts to take shape to our southwest. That one impacts the region tomorrow in a slightly less cold atmosphere, and also tracking a little further south and a little weaker, so this one will be more of a rain event and not as heavy, the bulk of it occurring late day and evening. The next one will be weaker still, and tracking north of the region, with a few rain showers favoring early Friday. And the low pressure parade continues with the next threat over the coming weekend.
TODAY: Cloudy start, then partial sun developing. Highs 45-52. Wind NW 10-20 MPH.
TONIGHT: Variably cloudy. Lows 30-37. Wind N up to 10 MPH.
WEDNESDAY: Clouding over. Afternoon rain favoring areas south of I-90. Highs 40-47. Wind NE 5-15 MPH.
WEDNESDAY NIGHT: Cloudy. Any rain ending. Temperatures steady 40-47. Wind E 10-20 MPH, higher gusts.
THURSDAY: Mostly cloudy. Highs 45-52. Wind variable 5-15 MPH.
THURSDAY NIGHT: Mostly cloudy. Chance of rain showers overnight. Lows 40-47. Wind SE 5-15 MPH.
FRIDAY: Mostly cloudy. Chance of rain showers morning. Highs 48-55. Wind S 5-15 MPH shifting to W.
FRIDAY NIGHT: Partly cloudy. Lows 30-37. Wind N 5-15 MPH.
SATURDAY: Mostly cloudy. Highs 43-50. Wind E up to 10 MPH.

DAYS 6-10 (MARCH 29-APRIL 2)
Low pressure brings a chance of rain March 29. High pressure brings drier weather March 30-31. Next low pressure system brings threat of rain later April 1 into April 2. Temperatures near to slightly above normal.

DAYS 11-15 (APRIL 3-7)
Cooler/drier April 3-4. Precipitation threat with low pressure in vicinity April 5-7.

Monday Forecast

7:30AM

DAYS 1-5 (MARCH 23-27)
3 low pressure systems will impact the region during the next 5 days. The first one arrives later today and tonight and there is not much change to the previous forecast. There will be cold enough air for several inches of snow favoring higher elevations of interior locations, but some snow will occur closer to Boston as well, while southeastern MA and RI end up receiving mainly rain from the system. Its cause will be a low pressure system exiting the Mid Atlantic and passing just south of New England. The pressure gradient between it and high pressure in eastern Canada will get the wind going pretty decently, with gusts in the 40-50 MPH range from the east over Cape Cod tonight. But this thing will be moving steadily away on Tuesday, which will show some improvement, but probably not complete clearing. The next low will approach on Wednesday, a day that likely starts dry but ends rather wet. We’ll have to see how much cold air is around for some interior higher elevation mix/snow but most of the region looks like it will receive rain from this system. Will monitor for changes. Another break on Thursday, but by Friday the next low pressure area approaches, the center of this one destined to pass north of the region, allowing the system to be accompanied by a little bit of a warm up and rain showers.
TODAY: Clouds allow periods of dimmed sunshine for a while before thickening up. Late-day snow develops except rain South Coast of RI & MA to South Shore of MA. Highs 35-42. Wind NE up to 10 MPH.
TONIGHT: Overcast. Rain South Coast RI & MA and South Shore MA with snow elsewhere evening, changing to rain southeast to northwest before tapering off overnight. Snow accumulation before changeover: coating to 2 inches Boston-Providence corridor including I-95 belt and I-495 belt south of I-90, 2-4 inches I-495 belt north of I-90 including Merrimack Valley and southeastern NH as well as southern Worcester County and through northwestern RI and eastern CT, 4-6 inches northern Worcester County to southwestern NH with isolated greater-than-6 inch amounts possible in highest elevations. Lows 31-38 evening, rising slightly overnight. Wind E 10-20 MPH except 20-30 MPH with gusts 40-50 MPH Cape Cod / Islands.
TUESDAY: Cloudy start, then partial sun developing. Highs 45-52. Wind NW 10-20 MPH.
TUESDAY NIGHT: Variably cloudy. Lows 30-37. Wind N up to 10 MPH.
WEDNESDAY: Clouding over. Afternoon rain arriving, some mix higher elevations north central MA and southwestern NH. Highs 38-45. Wind NE 5-15 MPH.
WEDNESDAY NIGHT: Cloudy. Rain evening, ending overnight. Temperatures rising to 40-47. Wind E 10-20 MPH, higher gusts.
THURSDAY: Mostly cloudy. Temperatures steady in the 40s. Wind variable 5-15 MPH.
THURSDAY NIGHT: Mostly cloudy. Temperatures steady in the 40s. Wind SE 5-15 MPH.
FRIDAY: Mostly cloudy. Chance of rain showers. Highs 50-57. Wind S 10-20 MPH.

DAYS 6-10 (MARCH 28-APRIL 1)
Some precipitation, probably rain, for a portion of the March 28-29 weekend as another in a series of low pressure areas moves through. Briefly drier to end March then the next storm threat arrives April 1.

DAYS 11-15 (APRIL 2-6)
Current indications continue for a tendency for high pressure in eastern Canada and a series of low pressure waves passing south of or over southern New England. This would be a cool and unsettled set-up.

Sunday Forecast

7:44AM

DAYS 1-5 (MARCH 22-26)
High pressure in eastern Canada provides dry but colder weather today and sets the stage for an early spring storm that will include snow. This will take place as low pressure moves off the Mid Atlantic Coast and tracks east northeastward near or just inside the 40/70 “benchmark” Monday night. There will be enough cold air in place for snow to dominate the first part of the storm (although it may start as rain initially in many coastal areas before some dynamic cooling drags down sufficiently cold air to flip it to snow. It will snow for the least amount of time over southeastern MA and RI where warmer air will be first to invade, and this snow-to-rain zone will progress north northwestward as the storm goes on, but will occur slowly enough so that measurable / plowable snow occurs in a fair amount of the I-95 belt northwestward, with highest amounts to occur in the higher elevations outside I-495 and north of I-90 (see details below on amounts). We’ll be in between systems on Tuesday, which probably will not see complete clearing, and then the next storm takes a similar track but in a slightly milder atmosphere for Wednesday. While I’m expecting some frozen precipitation to be involved in the second storm on Wednesday, I also expect more rain to be involved than the first system, so the snow should be more confined and have less impact than the first one. Thursday may be very much Tuesday as we again find ourselves between a departing low and another approaching low in an active pattern…
TODAY: Sunny. Highs 38-45. Wind N 5-15 MPH.
TONIGHT: Clear. Lows 28-35. Wind NE under 10 MPH.
MONDAY: Increasing cloudiness. Highs 38-45. Wind NE up to 10 MPH.
MONDAY NIGHT: Overcast. Snow/mix develops early then changes to rain but may remain snow/mix for longer away from coastal locations. Preliminary snowfall accumulation expectation: Coating-2 inches southeast of the I-95 belt, 2-4 inches I-95 belt and I-495 belt south of I-90, 4-6 inches I-495 belt north of I-90. Lows 28-35 evening, may rise slowly overnight. Wind NE 10-20 MPH.
TUESDAY: Cloudy start with mix/rain/drizzle/fog possible early, then breaking clouds. Highs 40-47. Wind N 5-15 MPH.
TUESDAY NIGHT: Cloudy. Lows 30-37. Wind NE up to 10 MPH.
WEDNESDAY: Overcast. Rain likely, except some mix/snow possible interior areas. Highs 35-42. Wind NE 10-20 MPH.
WEDNESDAY NIGHT: Cloudy. Areas of fog and drizzle. Temperatures rising into the 40s. Wind variable 5-15 MPH.
THURSDAY: Mostly cloudy. Temperatures steady in the 40s. Wind variable 5-15 MPH.

DAYS 6-10 (MARCH 27-31)
The next in a series of low pressure areas comes through the region March 27, but with a further north track and milder air resulting in rain showers. A follow up low pressure system a little further south brings a chance of rain for a portion of the March 28-29 weekend. Generally dry but cool weather followed this for the last couple days of March.

DAYS 11-15 (APRIL 1-5)
Current indications are for a tendency for high pressure in eastern Canada and a series of low pressure waves passing south of or over southern New England. This would be a cool and unsettled set-up.
