Tuesday Forecast

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.

Monday Forecast

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.

Sunday Forecast

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.

Saturday Forecast

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.

Friday Forecast

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.
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.

DAYS 6-10 (MAY 1-5)
The boundary between Canadian chill and southeastern US warmth will be nearby. This is an unsettled pattern and for this area likely near to below normal temperatures.

DAYS 11-15 (MAY 6-10)
Little change to the overall pattern of DAYS 6-10 to start, then may try to reverse and go milder and less unsettled.

Thursday Forecast

7:15AM

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.
Forecast details…
TODAY: Mostly sunny. Highs 55-62 coast, 62-69 interior, but cooling back especially coastal areas afternoon. Wind light variable with sea breezes.
TONIGHT: Increasing clouds. Lows 48-55. Wind light SE.
FRIDAY: Cloudy. A period of rain morning. Isolated rain showers afternoon. Highs 55-62 coast, 62-69 interior occurring late in the day. Wind SE 5-15 MPH shifting to SW with higher gusts.
FRIDAY NIGHT: Cloudy. Rain showers likely. Possible thunder. Lows 45-52. Wind S 10-20 MPH shifting to SW.
SATURDAY: Mostly cloudy. Scattered rain showers. Highs 52-59. Wind W to NW 10-20 MPH, higher gusts..
SATURDAY NIGHT: Partly cloudy. Lows 42-49. Wind NW 10-20 MPH.
SUNDAY: Clouding over. A period of rain or showers possible. Highs 56-63. Wind variable 5-15 MPH.
SUNDAY NIGHT: Cloudy. Rain, may mix with snow north and west of Boston before ending. Lows 35-42. Wind variable 5-15 MPH becoming N.
MONDAY: Clearing. Highs 55-60 coast, 60-65 interior. Wind NW 5-15 MPH becoming light variable with sea breezes.

DAYS 6-10 (APRIL 30-MAY 4)
The boundary between Canadian chill and southeastern US warmth will be nearby. This is an unsettled pattern with uncertain temperatures. Details unknown until much closer to these days.

DAYS 11-15 (MAY 5-9)
Little change to the overall pattern of DAYS 6-10 is expected during this time.

Wednesday Forecast

7:35AM

DAYS 1-5 (APRIL 24-28)
A cold front moved through the region overnight with more wet weather, and some low level moisture is trapped in the region early this morning, but a drying trend will be underway soon, and later today through Thursday will be decent as high pressure takes over the weather. But as advertised, the next low pressure area will be quick to move in and bring more wet weather Friday to early Saturday, leaving behind drier but blustery conditions for Saturday. The next unsettled weather system arrives Sunday but does not look too impressive right now.
Forecast details…
TODAY: Cloudy start with areas of fog and drizzle, then clearing. Highs 61-68. Wind light variable early then W increasing to 10-20 MPH.
TONIGHT: Mostly clear. Lows 40-47. Wind W 5-15 MPH.
THURSDAY: Mostly sunny. Highs 60-67, except cooler Cape Cod. Wind W 5-15 MPH.
THURSDAY NIGHT: Increasing clouds. Lows 48-55. Wind light SE.
FRIDAY: Cloudy. Rain showers likely from mid morning on. Highs 55-62, coolest coast. Wind SE 5-15 MPH.
FRIDAY NIGHT: Cloudy. Rain showers likely. Lows 45-52. Wind variable 5-15 MPH.
SATURDAY: Mostly cloudy with rain showers early, then sun/cloud mix. Highs 53-60. Wind NW 15-25 MPH.
SATURDAY NIGHT: Partly cloudy. Lows 42-49. Wind NW 5-15 MPH.
SUNDAY: Clouding over. A period of rain or showers possible. Highs 56-63. Wind variable 5-15 MPH.

DAYS 6-10 (APRIL 29-MAY 3)
Dry, cooler April 29. Transition with clouds and potential light rain April 30 or May 1 with a chance of getting into a warmer air mass. Probably back to the cool side of a boundary thereafter with some additional unsettled weather possible.

DAYS 11-15 (MAY 4-8)
Expecting the region to be near a boundary between warmth to the south and cool air to the north, with additional unsettled weather at times and a continued uncertain temperature forecast.

Tuesday Forecast

7:00AM

DAYS 1-5 (APRIL 23-27)
Low pressure drifts slowly away to the east today, and although there will be a slight drying process it will stay generally overcast. A frontal system crosses the region west to east in the early hours of Wednesday with more unsettled weather, followed by some improvement later Wednesday and Thursday as high pressure approaches then moves over the region. The active pattern means the next low pressure system will be quick to move in during Friday with more unsettled weather, and although this should move on out of the area by Saturday, it will do so while intensifying, so the drying weather will also be cool and breezy.
Forecast details…
TODAY: Cloudy. Periods of rain and drizzle, especially in the morning. Highs 53-60 except 60-67 southwestern NH and central MA. Wind NE to N 5-15 MPH, shifting to E later.
TONIGHT: Cloudy. Rain showers likely. Lows 43-50. Wind variable 5-15 MPH.
WEDNESDAY: Mostly cloudy with rain showers early morning, then partly sunny. Highs 59-66. Wind variable becoming W increasing to 10-20 MPH.
WEDNESDAY NIGHT: Partly cloudy. Lows 40-47. Wind W 5-15 MPH.
THURSDAY: Partly sunny. Highs 63-70, cooler Cape Cod. Wind W 5-15 MPH.
THURSDAY NIGHT: Increasing clouds. Lows 48-55. Wind SW 5-15 MPH.
FRIDAY: Mostly cloudy with rain showers. Highs 58-65, coolest Cape Cod. Wind SW 10-20 MPH.
FRIDAY NIGHT: Mostly cloudy with rain showers. Lows 45-52. Wind variable 5-15 MPH.
SATURDAY: Mostly cloudy with rain showers early, then sun/cloud mix. Highs 53-60. Wind NW 15-25 MPH.

DAYS 6-10 (APRIL 28-MAY 2)
Lots of transitions as one system moves through with a rain shower threat April 28 followed by a quick shot of fair and cooler weather for April 29, then a warm front lifts through April 30 or May 1 with a warming trend but some additional unsettled weather before the front drops back to the south again with a cool-down. Of course timing is approximate this far in advance.

DAYS 11-15 (MAY 3-7)
May end up near a boundary between warm air to the south and lingering Canadian cold, leaving the door open for unsettled weather and an uncertain temperature forecast.

Monday Forecast

7:42AM

DAYS 1-5 (APRIL 22-26)
Earth Day 2019. Locally we will see more greening up. We need rain to help that, right? Right. We’ll see it off and on this week, which will be rather unsettled. But we’ve been on the mild to warm side of late, but the next few days will be somewhat cooler. Low pressure forms offshore and moves up across eastern New England today and tonight, slowly departing Tuesday, as upper level low pressure crosses the region. Another low will pass north of the region Wednesday and send its cold front through here, and the next in a series of systems is due on Friday with more unsettled weather. Thursday may be the only day in this 5-day stretch without the threat of at least some rainfall. Forecast details…
TODAY: Partial sun early, then cloudy. Scattered to numerous rain showers developing from south to north, heaviest in eastern locations. Highs 58-65 occurring by midday then cooling somewhat. Wind light variable becoming NE 5-15 MPH.
TONIGHT: Cloudy. Periods of rain, possibly heavy. Lows 46-53. Wind NE 5-15 MPH, higher gusts near the coast.
TUESDAY: Cloudy. Periods of rain and drizzle, especially in the morning. Highs 53-60 except 60-67 southwestern NH and central MA. Wind NE to N 5-15 MPH.
TUESDAY NIGHT: Cloudy. Rain showers likely. Lows 43-50. Wind variable 5-15 MPH.
WEDNESDAY: Mostly cloudy with rain showers morning. Partly sunny afternoon. Highs 59-66. Wind variable becoming W increasing to 10-20 MPH.
WEDNESDAY NIGHT: Partly cloudy. Lows 40-47. Wind W 5-15 MPH.
THURSDAY: Partly sunny. Highs 63-70, cooler Cape Cod. Wind W 5-15 MPH.
THURSDAY NIGHT: Increasing clouds. Lows 48-55. Wind SW 5-15 MPH.
FRIDAY: Mostly cloudy with rain showers. Highs 58-65, coolest Cape Cod. Wind SW 10-20 MPH.

DAYS 6-10 (APRIL 27-MAY 1)
Gusty breeze, cooler, but mainly dry or isolated rain showers April 27. Next low pressure systems brings wet weather threat April 28. Fair, breezy, cooler to end April with a milder trend by the end of the period to start May.

DAYS 11-15 (MAY 2-6)
May end up near a boundary between warm air to the south and lingering Canadian cold, leaving the door open for unsettled weather and an uncertain temperature forecast.

Sunday Forecast

7:27AM

DAYS 1-5 (APRIL 21-25)
No big changes for this update. Unsettled pattern continues, though not excessively wet. We’ll also see a slight cooling trend the next couple days as upper level low pressure arrives Monday and hangs around into Tuesday before being replaced with another one on Wednesday, finally exiting Thursday when there should be a completely dry day for the region.
Forecast details…
TODAY: Mostly cloudy early morning with rain showers likely mainly eastern areas. Mostly cloudy to partly sunny with isolated rain showers thereafter. Highs 63-70, cooler South Coast. Wind S to SW 5-15 MPH, higher gusts possible.
TONIGHT: Mostly cloudy. Scattered rain showers. Lows 50-57. Wind SW 5-15 MPH.
MONDAY: Mostly cloudy. Scattered to numerous rain showers. Highs 55-62 coast, 61-68 interior. Wind variable 5-15 MPH.
MONDAY NIGHT: Mostly cloudy. Scattered rain showers. Lows 48-55. Wind variable 5-15 MPH.
TUESDAY: Mostly cloudy. Scattered rain showers. Highs 55-62 coast, 61-68 interior. Wind variable 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Scattered rain showers. Lows 48-55. Wind variable 5-15 MPH.
WEDNESDAY: Cloudy. Chance of rain. Highs 56-63 but may stay steady 48-55 closer to the coast. Wind variable to E 5-15 MPH.
WEDNESDAY NIGHT: Becoming partly cloudy. Patchy fog. Lows 43-50. Wind variable up to 10 MPH becoming W.
THURSDAY: Partly sunny. Highs 58-65 coast, 65-72 interior. Wind light W but coastal sea breezes likely.

DAYS 6-10 (APRIL 26-30)
A slight adjustment to a more progressive set-up with wet weather more likely April 26 and improvement during the April 27-28 weekend, then a mainly fair and somewhat milder end to the month.

DAYS 11-15 (MAY 1-5)
Fair, mild start, unsettled episode, then a cooler trend, is the current low confidence call.

Saturday Forecast

10:04AM

DAYS 1-5 (APRIL 20-24)
Everything going as expected as we remain in a warm and rather humid air mass. Boston set a record high minimum temperature on Friday with a 63, beating the old record of 60. This is the type of weather that makes the grass green up quickly and the vegetation emerge. Of course, for many it means worsening allergies too. Another down side to the pattern is with some rain combined with melting mountain snow, the river flood threat will be higher during the coming days. A plus to all of this is the fire danger, which has been rather high, will drop off. So there is a mix of positives and negatives, which one would expect. The axis of most numerous rain showers which has been the biggest headache in the forecast recently is behaving about as expected, but has rippled around a little overnight and into the morning, but will be mainly to the west for several hours before heading back to the east again, and it should be mainly offshore, except possibly Cape Cod, for improving weather during Sunday, which is Easter for those who celebrate (except Eastern Orthodox which is next week). I’ve been eyeing the good possibility of the trailing upper level low pressure from this system coming across the region Monday, “Earth Day”, with unsettled weather, and that will be the case. Think of it as an Earth Day watering for the continued emergence of green, if you will. And in true April fashion, yet another disturbance and front will be in the area to keep the unsettled pattern going into midweek.
Forecast details…
TODAY: Mostly cloudy. Rain showers and areas of drizzle. Most numerous rain showers west and north of Boston. Highs 63-70 except 56-63 South Coast. Wind S 10-20 MPH, higher gusts.
TONIGHT: Mostly cloudy. Numerous rain showers. Lows 50-57. Wind S 10-20 MPH, higher gusts possible.
SUNDAY: Mostly cloudy early morning with rain showers likely mainly eastern areas. Mostly cloudy to partly sunny with isolated rain showers thereafter. Highs 63-70, cooler South Coast. Wind S to SW 5-15 MPH, higher gusts possible.
SUNDAY NIGHT: Mostly cloudy. Scattered rain showers. Lows 50-57. Wind SW 5-15 MPH.
MONDAY: Mostly cloudy. Scattered to numerous rain showers. Highs 55-62 coast, 61-68 interior. Wind variable 5-15 MPH.
MONDAY NIGHT: Mostly cloudy. Scattered rain showers. Lows 48-55. Wind variable 5-15 MPH.
TUESDAY: Mostly cloudy. Scattered rain showers. Highs 55-62 coast, 61-68 interior. Wind variable 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Scattered rain showers. Lows 48-55. Wind variable 5-15 MPH.
WEDNESDAY: Cloudy. Chance of rain. Highs 56-63 but may stay steady 48-55 closer to the coast. Wind variable to E 5-15 MPH.

DAYS 6-10 (APRIL 25-29)
Should be a break in the wet weather early in the period, with mild conditions, before it returns sometime during the April 27-28 weekend, then departs at the end of the period when a shot of much cooler air is possible. Not the highest confidence on this forecast right now.

DAYS 11-15 (APRIL 30-MAY 4)
I have no idea. Ok, kidding, kind of. I’m not really too keen on any medium range guidance right now so I’ll venture this one on my own and call for fair weather to end April, and unsettled and cooler weather to start May.

Friday Forecast

8:37AM

DAYS 1-5 (APRIL 19-23)
Warm sector weather, as expected, for the next couple days. It means lots of clouds, and occasional threats for passing rain showers too. However, still not expecting any wash-out weather as in long lasting rains. We do increase the shower threat from west to east during Saturday and Saturday night as a weakening cold front crosses the region. This front should get just far enough east of the region to reduce the rain shower chance during Sunday, though this may not be true for Cape Cod. However, the parent low from this series of fronts (the warm front that went by yesterday and the cold front moving through this weekend) is going to cut off and drift across the region Monday with more unsettled weather. This has been an expected occurrence for a few days, but I think it may have a little more impact left for us than I thought on my update 24 hours ago. One other change I am going to make is hold back on bringing that cooler high pressure area closer to the region Tuesday. What this does is keep us milder, but still unsettled.
Forecast details…
TODAY: Partly sunny to mostly cloudy. Risk of passing rain showers. Highs 58-63 South Coast, 63-68 just inland from the South Coast and south-facing portions of the eastern MA coast, 68-75 elsewhere. Wind S to SW 10-20 MPH with higher gusts.
TONIGHT: Mostly cloudy. Scattered rain showers. Lows 53-60. Wind S 10-20 MPH, higher gusts.
SATURDAY: Mostly cloudy. Isolated rain showers but more numerous rain showers arriving west to east during the afternoon hours. Highs 61-68 except 55-62 South Coast. Wind S 10-20 MPH, higher gusts.
SATURDAY NIGHT: Mostly cloudy. Numerous rain showers. Lows 50-57. Wind S 10-20 MPH, higher gusts possible.
SUNDAY: Mostly cloudy early morning with rain showers likely mainly eastern areas. Mostly cloudy to partly sunny with isolated rain showers thereafter. Highs 63-70, cooler South Coast. Wind S to SW 5-15 MPH, higher gusts possible.
SUNDAY NIGHT: Mostly cloudy. Scattered rain showers. Lows 50-57. Wind SW 5-15 MPH.
MONDAY: Mostly cloudy. Scattered rain showers. Highs 55-62 coast, 61-68 interior. Wind variable 5-15 MPH.
MONDAY NIGHT: Mostly cloudy. Scattered rain showers. Lows 48-55. Wind variable 5-15 MPH.
TUESDAY: Mostly cloudy. Scattered rain showers. Highs 55-62 coast, 61-68 interior. Wind variable 5-15 MPH.

DAYS 6-10 (APRIL 24-28)
Additional wet weather possible April 24 and again later April 27-28. Temperatures near to above normal, but quick cool shot possible end of period.

DAYS 11-15 (APRIL 29-MAY 3)
Fair, milder early period, a period of unsettled weather may start May off as it trends slightly cooler. Continued low confidence forecast.

Thursday Forecast

7:38AM

DAYS 1-5 (APRIL 18-22)
Quick update today due to time constraints in my schedule! Warm front approaches today, crosses tonight, minor precipitation associated with it. Warm sector weather dominates Friday and Saturday as low pressure crawls through the Tennessee Valley to the Great Lakes and sends a weakening cold front ahead of it, which will cross the region late Saturday to early Sunday as it basically dissipates. While rain shower activity will be associated with this, the heaviest and most concentrated band of showers may be broken enough to “skip” some areas and where they do occur they may not be there for very long. Still a few details to fine-tune with that, but the timing currently looks like wettest weather will occur Saturday night. Weakening upper level low pressure will be in the vicinity on Monday with mild and slightly unsettled weather.
Forecast details…
TODAY: Mostly cloudy. Scattered rain showers that may mix with sleet in a few places early to mid morning. Patchy drizzle and a risk of very light rain later in the day. Highs 54-61. Wind light SE.
TONIGHT: Mostly cloudy. Lows 48-55. Wind S increasing to 10-20 MPH.
FRIDAY: Partly sunny. Risk of passing rain showers. Highs 58-63 South Coast, 63-68 just inland from the South Coast and south-facing portions of the eastern MA coast, 68-75 elsewhere. Wind S to SW 10-20 MPH with higher gusts.
FRIDAY NIGHT: Mostly cloudy. Scattered rain showers. Lows 51-58. Wind S 10-20 MPH, higher gusts.
SATURDAY: Mostly cloudy. Isolated rain showers but more numerous rain showers west of Boston late-day. Highs 61-68 except 55-60 South Coast. Wind S 10-20 MPH, higher gusts.
SATURDAY NIGHT: Mostly cloudy. Numerous rain showers. Lows 50-57. Wind S 10-20 MPH, higher gusts possible.
SUNDAY: Mostly cloudy early morning with rain showers likely mainly eastern areas. Partly sunny with isolated rain showers thereafter.
Highs 63-70, cooler South Coast. Wind S to SW 5-15 MPH, higher gusts possible.
SUNDAY NIGHT: Partly cloudy. Isolated rain showers. Lows 50-57. Wind SW 5-15 MPH.
MONDAY: Partly sunny. Isolated rain showers. Highs 66-73 except cooler south-facing shores. Wind SW 5-15 MPH.

DAYS 6-10 (APRIL 23-27)
A push of cooler air with high pressure from Canada to start the period, then a frontal boundary nearby and a series of low pressure areas bringing unsettled weather at times for the balance of the period, with greatest rain threats based on current timing coming later April 24 and later April 27.

DAYS 11-15 (APRIL 28-MAY 2)
Low pressure with mild and unsettled weather to start the period then dry and mild end to April and cooler air possible to start May. Continued low confidence forecast.

Wednesday Forecast

7:19AM

DAYS 1-5 (APRIL 17-21)
Not alot of adjustment to be made to the forecast in the short term. High pressure controls the weather today which will be quite nice, but the famous coastal sea breeze will be at work chilling those areas to 10 or more degrees lower than some inland locations this afternoon. High pressure slides offshore and a warm front crosses the region slowly on Thursday, which will be an overcast day with a threat of some wet weather, but no heavy rainfall. We then enter a broad warm sector with a southerly air flow which will remain with us from Friday through the weekend as low pressure cuts off in the Tennessee Valley and drifts slowly toward New England. Rain showers are possible during the Friday-Sunday period, but will likely be concentrated in a 12 hour window sometime Friday night to the middle of Saturday, as timing stands now. This may have to be adjusted so watch comments and future updates for my ideas on what may happen.

DAYS 6-10 (APRIL 22-26)
One upper level low dissipates while drifting through the region early in the period while a second one approaches from the west and moves through mid period, combined with a front in the vicinity, to bring the best chance of wet weather around April 24. Less threat of rain later in the period. Temperatures near to above normal.

DAYS 11-15 (APRIL 27-MAY 1)
Another low pressure area may impact the region with occasional wet weather favoring April 27-28 before drier weather and a shot of cooler air to end the month and start May. Low confidence forecast.

DAYS 1-5 (APRIL 16-20)
We’ll still be in the wind zone between low pressure in eastern Canada and high pressure approaching from the Great Lakes / Ohio Valley today, a bright but blustery day. High pressure brings more tranquil weather for Wednesday. A warm front crosses the region Thursday with cloudiness and perhaps a little wet weather, then the warm sector takes over for the end of the week with clouds dominant and a rain shower threat which becomes greatest Friday night and Saturday.

DAYS 6-10 (APRIL 21-25)
Upper level low pressure drifts from the Tennessee Valley to just south of New England while gradually weakening early to mid period, replaced by a second one before that one pulls away. This is an unsettled pattern overall with the greatest wet weather threats in the April 22-24 time frame as it stands now. Temperatures near to slightly above normal.

DAYS 11-15 (APRIL 26-30)
Another low pressure area may impact the region with occasional wet weather favoring April 27-28 before drier weather and a shot of cooler air to end the month.
