7:12AM

DAYS 1-5 (APRIL 30-MAY 4)
Low pressure sits atop southeastern New England today, another cool and somewhat unsettled day. This low exits stage east on Tuesday, opening the door to a westerly flow over the top of a high pressure ridge along the US East Coast and a summer preview mid to late week. By Friday, a cold front will be close enough to the region to introduce the chance of some passing showers and thunderstorms as well. Detailed forecast…
TODAY: Mostly cloudy. Isolated to scattered rain showers. A few may contain brief downpours and small hail. Highs 52-59. W 5-15 MPH shifting to N.
TONIGHT: Mostly cloudy. Isolated rain showers early. Lows 42-49. Wind N 5-15 MPH.
TUESDAY: Partly cloudy. Isolated rain showers midday. Highs 57-63 South Coast, 64-71 elsewhere. Wind NW 5-15 MPH.
TUESDAY NIGHT: Clearing. Lows 47-54. Wind W 5-15 MPH.
WEDNESDAY: Mostly sunny. Highs 66-74 South Coast, 75-83 elsewhere. Wind W 10-20 MPH.
THURSDAY: Partly cloudy. Lows from the middle 50s to lower 60s. Highs from the upper 60s to middle 70s South Coast, upper 70s to middle 80s elsewhere.
FRIDAY: Partly sunny. Chance of showers and thunderstorms. Lows from the upper 50s to lower 60s. Highs from the upper 60s to middle 70s South Coast, upper 70s to middle 80s elsewhere.

DAYS 6-10 (MAY 5-9)
A front will be in the region for much of this period with temperature swings and also the risk of a few episode of wet weather. However there will be stretches of fair weather as well. Timing and details uncertain at this point.

DAYS 11-15 (MAY 10-14)
For now staying with the outlook for a typical springtime up/down temperature pattern with a few episodes of unsettled weather.

7:28AM

DAYS 1-5 (APRIL 29-MAY 3)
Low pressure moves in today and then spins around and does a mini loop over New England as if to remind us of the stormy pattern we endured not so long ago, but also like a farewell as we have a big change in the weather pattern above to take place right as the month changes. This is when high pressure will build along the East Coast as the low departs and brings a taste of summer weather to the region. Detailed forecast…
TODAY: Mainly cloudy. Rain showers likely, most numerous mid to late morning southwestern NH, central MA, and eastern CT, and most numerous late morning and midday southeastern NH, eastern MA, and RI. Highs 55-62. Wind variable 5-10 MPH.
TONIGHT: Variably cloudy. Isolated rain showers. Lows 45-51. Wind W 5-15 MPH.
MONDAY: Mostly cloudy. Isolated to scattered rain showers. Highs 52-59. W 5-15 MPH shifting to N.
MONDAY NIGHT: Mostly cloudy. Lows 42-49. Wind N 5-15 MPH.
TUESDAY: Partly cloudy. Highs 57-63 South Coast, 64-71 elsewhere. Wind W 5-15 MPH.
WEDNESDAY: Mostly sunny. Lows in the 50s. Highs from the upper 60s to middle 70s South Coast, upper 70s to lower 80s elsewhere.
THURSDAY: Partly cloudy. Lows from the middle 50s to lower 60s. Highs from the upper 60s to middle 70s South Coast, upper 70s to middle 80s elsewhere.

DAYS 6-10 (MAY 4-8)
A front will be in the region for much of this period so timing it in regards to temperature and precipitation threats is difficult this far in advance. Preliminary call is that May 4 is warm but brings a risk of showers, May 5 is cooler but the South Coast may run a rain risk, May 6 is warmer with a slight risk of showers, then additional temperature fluctuations and shower threats possible May 7-8 also. Don’t read this as a rainy period of days as there will probably be stretches of very nice weather between wet weather threats.

DAYS 11-15 (MAY 9-13)
For now going with a typical springtime up/down temperature pattern with a few episodes of unsettled weather.

2:10AM

DAYS 1-5 (APRIL 28-MAY 2)
A split weekend with a fair/mild day today then a cooler/unsettled day Sunday as a front moves in, and stalls over the region as low pressure cuts off over northern New England. This low will then sit and spin through Monday, keeping it unsettle, before departing as May begins, with fair weather returning Tuesday and continuing Wednesday as a high pressure ridge strengthening to the south of the region brings an increasing westerly flow and a taste of summer. Forecast details…
TODAY: Low clouds and areas of fog early, then sunshine. Highs 57-66 coast, 67-74 inland. Wind S to SW 5-15 MPH.
TONIGHT: Partly to mostly cloudy. Lows 46-54. Wind S under 10 MPH.
SUNDAY: Mostly cloudy. Rain showers likely morning and midday becoming less numerous thereafter. Highs 55-62. Wind variable 5-15 MPH.
SUNDAY NIGHT: Variably cloudy. Isolated rain showers. Lows 45-51. Wind W 5-15 MPH.
MONDAY: Variably cloudy. Isolated to scattered rain showers. Highs 55-63. Wind NW 10-20 MPH.
TUESDAY: Partly cloudy. Lows in the 40s. Highs in the 60s.
WEDNESDAY: Mostly sunny. Lows in the 50s. Highs from the upper 60s to middle 70s South Coast, upper 70s to lower 80s elsewhere.

DAYS 6-10 (MAY 3-7)
The feel of summer hangs on May 3 with dry, breezy, warm weather except a little cooler in typical areas near the South Coast. Cold front drops into the region May 4 with clouds and rain showers likely but still mild. Cooler May 5 and the front may hang up south of the region with clouds dominating and some additional wet weather possible near the South Coast. The front may lift north again May 6 putting the region back into the warm side but still with a risk of rain showers and possible thunderstorms, before dropping south of the region with cooler and still potentially unsettled weather May 7. The forecast for the middle and end of this period is low confidence.

DAYS 11-15 (MAY 8-12)
For now going with a typical springtime up/down temperature pattern with a few episodes of unsettled weather, that most likely early and again late in the period with fair weather dominating in between. However this far out timing is uncertain.

6:59AM

DAYS 1-5 (APRIL 27-MAY 1)
A wave of low pressure moves rapidly northeastward and brings a return to wet weather this afternoon and evening to southeastern New England. Behind this we get into a mild southwesterly air flow ahead of a cold front on Saturday. This front will bring rain showers to the region Saturday night but a rapidly closing-off upper low will then slow the front and allow a wave of low pressure to develop on it, however already north of the region, but close enough to prolong unsettled weather to some extent through all of Sunday and Monday. This represents a change in the expected scenario from previous forecasts. The upper low will be moving away by Tuesday which will be a fair weather day to start the month of May. Forecast details…
TODAY: Partly sunny morning. Cloudy afternoon with periods of rain with embedded heavier showers by late in the day. Highs 56-64, coolest coast. Wind light SE.
TONIGHT: Cloudy evening with rain showers and possible thunderstorms with locally heavy rain. Mostly cloudy overnight with areas of fog and isolated rain showers. Lows 48-55. Wind light SE to S.
SATURDAY: Mostly sunny to partly cloudy. Highs 58-64 South Coast, 65-72 elsewhere. Wind S to SW 5-15 MPH.
SATURDAY NIGHT: Mostly cloudy with rain showers and a chance of thunderstorms. Lows 50-57. Wind SW up to 10 MPH.
SUNDAY: Cloudy with rain showers morning. Variably cloudy with scattered rain showers afternoon. Highs 58-64. Wind SW 5-15 MPH.
MONDAY: Variably cloudy. Chance of rain showers. Lows from the upper 40s to lower 50s. Highs from the upper 50s to lower 60s.
TUESDAY: Partly sunny. Lows in the 40s. Highs in the 60s.

DAYS 6-10 (MAY 2-6)
High pressure along the East Coast and a westerly air flow over southeastern New England will bring a summer preview with fair and very warm weather May 2-3 with warmth continuing into May 4 though there may be showers and thunderstorms in the area as a cold front approaches. This front should get just south of the region for the May 5-6 weekend which may feature more cloudiness and a few episodes of rain showers along with somewhat cooler weather.

DAYS 11-15 (MAY 7-11)
Unsettled weather early in the period then a trend toward fair weather. Temperatures near to above normal.

7:44AM

DAYS 1-5 (APRIL 26-30)
A low pressure area departs slowly today with improving weather, but the next one will return wet weather to the region later Friday as it tracks north northeastward into New England. But this one will make a quick exit by Saturday morning leaving most of the weekend dry with just a risk of a passing rain shower later Saturday from a cold front. This front will bring a shot of cool air in for the second half of the weekend. Forecast details…
TODAY: Overcast with areas of fog, drizzle, and periods of rain, especially eastern areas, during the morning. Clearing this afternoon. Highs 57-63 South Coast, 63-69 elsewhere. Wind light S early, then W increasing to 10-20 MPH afternoon.
TONIGHT: Mostly clear. Lows 39-46. Wind W 5-15 MPH, diminishing.
FRIDAY: Increasing clouds. Rain arriving southwest to northeast later in the day. Highs 56-64, coolest coastal areas. Wind variable 5-15 MPH.
FRIDAY NIGHT: Cloudy with rain likely and a slight chance of thunderstorms, ending before dawn. Lows 48-55. Wind light variable.
SATURDAY: Partly cloudy. Slight risk of a passing rain shower mainly late day. Highs 58-65 South Coast, 65-72 elsewhere. Wind SW 5-15 MPH.
SUNDAY: Partly cloudy and windy. Lows from the upper 30s to lower 40s. Highs from the middle 50s to lower 60s.
MONDAY: Mostly sunny. Lows from the middle 30s to lower 40s. Highs from the middle 50s to lower 60s.

DAYS 6-10 (MAY 1-5)
A large high pressure ridge builds over the East Coast to start May with fair weather and above to much above normal temperatures, but a front may get close by late period with a rain shower or thunderstorm risk.

DAYS 11-15 (MAY 6-10)
Watching for a front in the area early period with a risk of rain showers and to determine if it will remain anomalously warm or cool off a bit. More unsettled weather is expected mid period with dry and cooler weather late period.

7:09AM

DAYS 1-5 (APRIL 25-29)
Low pressure tracks northeastward from the Mid Atlantic through southern New England today through early Thursday with unsettled weather which will include some moderate to heavy rain showers mainly this afternoon and evening, including the risk of some thunder as well. Improving weather arrives later Thursday but another low pressure area, this one smaller, will race northeastward and bring another rain threat later Friday into Friday evening. A cold front charges across the region from west to east Saturday but will be starved for moisture and present only the threat of a passing rain shower. It will open the door for a shot of chilly fair from Canada Saturday night and Sunday. Forecast details…
TODAY: Overcast. A couple periods of light rain possible morning. Numerous rain showers, some heavy, and possible thunderstorms this afternoon. Highs 52-58. Wind SE to S 10-20 MPH.
TONIGHT: Cloudy. Scattered showers. Patchy fog. Lows 44-50. Wind S to SW 5-15 MPH.
THURSDAY: Mostly cloudy to partly sunny. Chance of rain showers early. Highs 55-63, coolest South Coast. Wind SW to W 10-20 MPH.
THURSDAY NIGHT: Mostly clear. Lows 39-46. Wind W 5-15 MPH, diminishing.
FRIDAY: Mostly cloudy. Chance of rain afternoon and evening. Highs 56-64, coolest coastal areas. Wind variable 5-15 MPH.
SATURDAY: Partly cloudy and breezy. Slight risk of a passing rain shower. Lows from the upper 40s to middle 50s. Highs in the 60s.
SUNDAY: Partly cloudy and windy. Lows from the upper 30s to lower 40s. Highs in the 50s.

DAYS 6-10 (APRIL 30-MAY 4)
Surface high pressure crosses the region April 30 with a fair cold start and milder finish. A large high pressure ridge builds over the East Coast to start May with fair weather and above to much above normal temperatures, but a front may get close by late period with a rain shower or thunderstorm risk.

DAYS 11-15 (MAY 5-9)
Watching for a front in the area early period with a risk of rain showers and to determine if it will remain anomalously warm or cool off a bit. More unsettled weather is expected mid period with dry and cooler weather late period.

7:35AM

DAYS 1-5 (APRIL 24-28)
High pressure drifts to the east of New England today but fair and mild weather hangs on, except the typical cooler spring air at the coast. Low pressure will track northeastward from the Mid Atlantic through New England Wednesday with wet weather, pulling way Thursday with improving weather. A follow-up but smaller low pressure area will track northeastward and over or just east of New England by late Friday or very early Saturday with some additional rain possible. By Saturday, a cold front will approach from the west but may hold off its shower threat until late day or night.
Detailed forecast…
TODAY: Mostly sunny morning. Partly cloudy afternoon. Highs 57-63 coast and 64-70 interior but will fall midday and afternoon South Coast and late day East Coast. Wind SW to SE 5-15 MPH.
TONIGHT: Clouding up. Rain arriving southwest to northeast overnight. Lows 43-49. Wind SE 5-15 MPH.
WEDNESDAY: Cloudy with rain likely morning. Mostly cloudy with rain showers likely and thunderstorms possible afternoon. Highs 52-58. Wind SE to S 10-20 MPH.
WEDNESDAY NIGHT: Cloudy. Scattered showers. Patchy fog. Lows 44-50. Wind S to SW 5-15 MPH.
THURSDAY: Mostly cloudy to partly sunny. Chance of rain showers early. Highs 55-63, coolest South Coast. Wind SW to W 10-20 MPH.
FRIDAY: Partly sunny to mostly cloudy. A period of rain possible late day to late night. Lows in the 40s. Highs from the upper 50s to middle 60s.
SATURDAY: Partly sunny. Late day rain showers possible. Lows from the upper 40s to middle 50s. Highs in the 60s.

DAYS 6-10 (APRIL 29-MAY 3)
Breezy, cooler, dry April 29 then fair and seasonable April 30 as an upper low pressure trough departs and surface high pressure approaches from the west. A building ridge of high pressure along the East Coast and the lack of surface high pressure in Canada is a recipe for fair weather and above to much above normal temperatures during the first few days of May.

DAYS 11-15 (MAY 4-8)
High pressure should dominate with a fair and warm start to this period then a couple disturbances eventually bring a shower risk and some slight cooling but temperatures still likely remaining above normal through the end of the period.

7:33AM

DAYS 1-5 (APRIL 23-27)
High pressure sits atop southern New England today providing a great spring day, then slides enough for a breeze but not enough to take away the sun for most of Tuesday, however that breeze will be a cool one along the South Coast, then East Coast by late in the day, while being a mild breeze over the interior. Low pressure will move through the region Wednesday with wet weather as it tracks southwest to northeast, and instability behind it will hold some cloudiness and a chance of showers in the region for at least a portion of Thursday. A cold front will approach late Friday but most of that day should be dry with current timing suggesting the wet weather will be at night. Detailed forecast…
TODAY: Sunny. Highs 56-62 coast, 63-69 interior. Wind light variable with sea breezes.
TONIGHT: Mostly clear. Lows 35-43, coolest interior valleys. Wind light variable.
TUESDAY: Mostly sunny morning. Partly cloudy afternoon. Highs 57-63 coast and 64-70 interior but will fall midday and afternoon South Coast and late day East Coast. Wind SW to SE 5-15 MPH.
TUESDAY NIGHT: Clouding up. Periods of rain overnight. Lows 43-49. Wind SE 5-15 MPH.
WEDNESDAY: Cloudy with rain likely morning. Mostly cloudy with rain showers likely afternoon. Highs 52-58. Wind SE to S 10-20 MPH.
THURSDAY: Mostly cloudy to partly sunny. Chance of rain showers mostly morning. Lows in the 40s. Highs from the upper 50s to lower 60s.
FRIDAY: Partly sunny to mostly cloudy. Rain showers likely at night. Lows in the 40s. Highs from the upper 50s to middle 60s.

DAYS 6-10 (APRIL 28-MAY 2)
A look at the April 28-29 weekend shows that cold fronts should pass by early Saturday and early Sunday with a cooling trend. Both days should feature some kind of sun/cloud mix but cannot rule out a few rain showers. Mainly fair weather a warming trend expected April 30 into the first couple days of May as a progressive pattern continues.

DAYS 11-15 (MAY 3-7)
Early call on this period is continued progression of systems with a warm start with fair weather then a cooling trend and more unsettled with a couple weather systems bringing the threat of wet weather at times.

8:27AM

DAYS 1-5 (APRIL 22-26)
This update is similar to yesterday’s but one change it to slow the timing of the onset of the wet weather and confine it more to midweek. Forecast update…
TODAY: Mostly sunny. Highs 52-58 coast, 58-64 interior. Wind N up to 10 MPH with coastal sea breezes.
TONIGHT: Mostly clear. Lows 33-40. Wind light variable.
MONDAY: Sunny. Highs 53-59 coast, 59-65 interior. Wind light variable with coastal sea breezes.
MONDAY NIGHT: Mostly clear. Lows 36-43. Wind light variable.
TUESDAY: Mostly sunny to partly cloudy. Highs 55-62 coast, 63-70 interior, but cooler especially coast afternoon. Wind light S to SE.
WEDNESDAY: Cloudy. Rain likely. Lows from the middle to upper 40s. Highs from the lower to middle 50s.
THURSDAY: Mostly cloudy. Occasional rain showers. Lows from the middle 40s to lower 50s. Highs from the middle to upper 50s.

DAYS 6-10 (APRIL 27-MAY 1)
A frontal system brings a rain shower threat late Friday, and a trough brings a few additional showers then a shot of very cool air over the April 28-29 weekend before it recovers and warms a bit April 30 and May 1 with fair weather.

DAYS 11-15 (MAY 2-6)
With low confidence I will call for a progressive pattern for this period with a fair, warmer May 2-3, then a cooling trend with potential unsettled weather after that.

8:42AM

DAYS 1-5 (APRIL 21-25)
First, a star gazing note: The Lyrid Meteor Shower peaks tonight, or in the early hours of Sunday, between midnight and dawn, with up to 20 meteors per hour possible. The sky conditions will be favorable for viewing this event with moon setting just after 1:30AM and no clouds.
High pressure will bring fair weather with a slow warming trend into Tuesday, along with typical cooling sea breezes in coastal locations. Low pressure will approach from the southwest later Tuesday with the risk of some wet weather arriving before the end of the day, continuing into Wednesday as the low moves through the region.
TODAY: Mostly sunny to partly cloudy. Highs 48-53 coast, 54-59 interior. Wind N up to 10 MPH with coastal sea breezes.
TONIGHT: Mostly clear. Lows 30-37. Wind N up to 10 MPH.
SUNDAY: Mostly sunny. Highs 50-55 coast, 56-61 interior. Wind N up to 10 MPH with coastal sea breezes.
SUNDAY NIGHT: Mostly clear. Lows 32-39. Wind light variable.
MONDAY: Sunny. Highs 52-57 coast, 58-63 interior. Wind light variable with coastal sea breezes.
TUESDAY: Increasing clouds. Chance of rain late. Lows from middle to upper 40s. Highs in the 60s except 50s immediate coast.
WEDNESDAY: Mostly cloudy. Rain tapering to rain showers. Lows in the 40s. Highs in the 50s.

DAYS 6-10 (APRIL 26-30)
Additional disturbances will bring a chance of rain and rain showers April 26-27. Drier, breezy, cool April 28-30.

DAYS 11-15 (MAY 1-5)
I continue to have uncertainty about the pattern as May begins. I’ve seen computer-guidance hints of things ranging from a continuation of the April pattern to a quick shift to more persistent warmth to the rapid development of an omega block with this area on the unsettled side of it. If I had to lean toward any of these for the first 5 days of the month, it’s persistence of the pattern ongoing now through the next 10 days. This would probably mean a front or low pressure system would visit the region about 2 times during that 5 day period, so there will be plenty to work out, as far as detail and timing.

7:38AM

DAYS 1-5 (APRIL 19-23)
Southern New England will sit between departing low pressure to the east and approaching high pressure from the west today, with some cold air aloft, and this will result in a gusty breeze and a cloud/sun mix with a couple showers possibly popping up due to marginal instability. After that, it’s dry weather as high pressure gains more control through the weekend and Monday, and at least into Tuesday. The next low pressure system will approach from the southwest late Tuesday and I’m currently favoring a faster timing for its arrival, meaning that wet weather is possible before Tuesday is done. Forecast details…
TODAY: Sun/cloud mix. A passing rain shower possible. Highs 44-50. Wind N 10-20 MPH.
TONIGHT: Partly cloudy. Lows 32-38. Wind N 5-15 MPH, higher gusts.
SATURDAY: Mostly sunny to partly cloudy. Highs 48-54. Wind N 5-15 MPH, higher gusts.
SATURDAY NIGHT: Mostly clear. Lows 30-37. Wind N 5-15 MPH.
SUNDAY: Mostly sunny. Highs 50-57. Wind N 5-15 MPH.
MONDAY: Sunny. Lows from the upper 30s to lower 40s. Highs from the middle 50s to lower 60s but turning cooler in coastal areas.
TUESDAY: Increasing clouds. Chance of rain late. Lows from middle to upper 40s. Highs in the 60s except 50s immediate coast.

DAYS 6-10 (APRIL 25-29)
A complex low pressure system will bring periods of rain April 25 to early April 27 followed by drier weather for April 28-29 weekend. Temperatures fairly close to normal.

DAYS 11-15 (APRIL 30-MAY 4)
A little uncertainty on the pattern at this point. Leaning toward a couple frontal passages with rain shower threats. Temperatures warmer early then trending cooler.

7:13AM

DAYS 1-5 (APRIL 19-23)
Low pressure will track just south of southern New England today and tonight then become absorbed by a larger low pressure circulation over the western Atlantic Friday as high pressure situates itself over the eastern Great Lakes. This will deliver some wet weather to the region today which may fall as sleet and/or snow in parts of the region at times especially this morning under heaviest areas and in higher elevations, then the steadiest is gone by afternoon and only intermittent light rain/mix showers are possible through tonight and a few lingering into Friday. Dry weather follows this weekend but with high pressure centered to the northwest of New England a cool northerly air flow will prevail. By Monday the high pressure area will build over the region with a bright and pleasant day. Forecast details…
TODAY: Cloudy with rain and areas of sleet and wet snow this morning with minor temporary accumulation possible on unpaved surfaces where frozen precipitation occurs, then intermittent mainly rain showers this afternoon. Highs 37-45. Wind NE 5-15 MPH with higher gusts especially near the coast, shifting to N later.
TONIGHT: Cloudy with a few rain/mix showers possible. Lows 33-39. Wind N 10-20 MPH.
FRIDAY: Mostly cloudy with passing rain/mix showers. Highs 42-48. Wind N 10-20 MPH.
FRIDAY NIGHT: Partly cloudy. Lows 32-38. Wind N 5-15 MPH, higher gusts.
SATURDAY: Partly cloudy. Highs 48-54. Wind N 5-15 MPH, higher gusts.
SUNDAY: Partly cloudy. Lows in the 30s. Highs in the 50s.
MONDAY: Sunny. Lows from the upper 30s to lower 40s. Highs from the middle 50s to lower 60s but turning cooler in coastal areas.

DAYS 6-10 (APRIL 24-28)
Going to lean toward a sooner arrival of low pressure from the southwest with a chance of rain by late April 24 into early April 25. A second system may bring additional unsettled weather later April 26 into April 27 with drier weather returning to end the period. Temperatures a little closer to normal during this period overall.

DAYS 11-15 (APRIL 29-MAY 3)
Fair, briefly cooler then milder April 29-30 before a risk of unsettled weather to start the month of May.

7:26AM

DAYS 1-5 (APRIL 18-22)
A broad low pressure circulation will still have an impact on the region today as southern New England sits on its western flank as a very small high pressure bubble slides south of the region. This combination results in a gusty west wind, some clouds, but dry conditions. Approaching low pressure from the Ohio Valley will track just south of southern New England Thursday and Thursday night, and will become part of the larger circulation offshore by Friday, bringing some rain and snow Thursday and lingering rain/snow showers on Friday, with snow being most likely in higher elevations of southwestern NH into north central MA, though some areas close to Boston may see flakes Thursday night and first thing Friday as well. The only threat of minor accumulation exists in the aforementioned higher elevations. High pressure approaches slowly over the weekend with dry weather but a cool north to northwest air flow. Forecast details…
TODAY: Partly sunny. Highs 49-56. Wind W 10-20 MPH with higher gusts.
TONIGHT: Mostly cloudy. Lows 36-43. Wind W 5-15 MPH, diminishing overnight.
THURSDAY: Cloudy with rain likely, may mix with or turn to snow higher elevations southwestern NH and north central MA. Highs 40-47 early then temperatures falling to 35-43. Wind NE 10-20 MPH, higher gusts near the coast.
THURSDAY NIGHT: Cloudy with rain, mix, and snow, gradually tapering off but a small snow accumulation is most likely in higher elevations of north central MA and southwestern NH. Lows 32-39. Wind N 10-20 MPH.
FRIDAY: Mostly cloudy with passing rain/mix showers. Highs 42-48. Wind N 10-20 MPH.
SATURDAY: Partly cloudy. Lows in the 30s. Highs from the upper 40s to middle 50s.
SUNDAY: Partly cloudy. Lows in the 30s. Highs in the 50s.

DAYS 6-10 (APRIL 23-27)
At the moment it looks like high pressure will dominate April 23-25 with fair weather and a warming trend with the exception of cooler sea breezes at coastal locations. Low pressure from the southwest may bring wet weather to the region during the April 26-27 period with a cooling trend.

DAYS 11-15 (APRIL 28-MAY 2)
Fair weather returns for the end of April with more seasonable temperatures. Another low pressure system may bring some unsettled weather during the first couple days of May.

7:20AM

DAYS 1-5 (APRIL 17-21)
Upper level low pressure tracks eastward across New England today, triggering scattered showers. High pressure brings fair weather Wednesday. Low pressure moves rapidly east and passes over or just south of southern New England during Thursday, which will be a wet day. Enough cold air may work in for some mixing with snow northwest of Boston at night, and a few rain and evening mixed rain/snow showers will occur behind the system Friday as the surface system departs but upper level low pressure will still have to cross the region. High pressure will build across eastern Canada by Saturday but this time it will be configured in such a way that it will deliver fair weather to the region with a northwest to north wind. Forecast details…
TODAY: Sunny to partly cloudy morning. Mostly cloudy with scattered showers afternoon. Highs 47-54. Wind SW to W 10-20 MPH.
TONIGHT: Mostly cloudy. Scattered rain and/or snow showers earoy. Lows 32-39. Wind W 10-20 MPH.
WEDNESDAY: Partly cloudy. Highs 48-55. Wind WNW 10-20 MPH, diminishing late.
WEDNESDAY NIGHT: Clouding over. Lows 34-40. Wind variable up to 10 MPH.
THURSDAY: Cloudy with periods of rain, may mix with snow far northwest of Boston at night. Highs 43-51. Wind E 10-20 MPH, shifting to N late.
FRIDAY: Mostly cloudy. Scattered rain/mix showers. Lows from the upper 30s to lower 40s. Highs from the middle 40s to lower 50s.
SATURDAY: Partly cloudy. Lows from the middle 30s to lower 40s. Highs from the upper 40s to middle 50s.

DAYS 6-10 (APRIL 22-26)
High pressure should protect the region with dry weather April 22-23. Low pressure threatens to bring wet weather sometime during the April 24-26 period. Temperatures mainly below normal.

DAYS 11-15 (APRIL 27-MAY 1)
A little more pattern amplification is possible but initially we may end up on the warm side of it and cannot rule out a couple very warm days before April ends.

8:17AM

DAYS 1-5 (APRIL 16-20)
Well the question of whether or not the Red Sox game on Patriots Day would be postponed for only the 5th time was answered yesterday, and that answer was yes, making 2018 join 1959, 1961, 1965, and 1984 as the only years the Marathon Monday baseball game was put off. The marathon on the other hand, well it would take a foot of snow or extremely severe weather to cause a postponement of that event, and since neither of those are very likely in mid April, despite our tendency to have some miserable weather at this time of year, it’s a good time to hold a rain or shine outdoor event. This year, it will be all about the rain and not at all about the shine, at least in terms of the sun. Hopefully all the participants will shine in their own way, from the elite competitors to those just joining in to see how far they can go and not worry about how long it takes them to get there. So while these participants battle themselves and in some cases other competitors, they will be battling the elements as well, in terms of cold, damp, wind, and wet weather. But keep in mind, many of them have trained long hours in equally harsh or even more harsh conditions in the weeks and months leading to this event, and they are not about to let a very unpleasant April day get in the way of their ultimate goal. When it comes down to it, today’s nasty weather will be more of a challenge for spectators than it will be for participants. I wish them all the best. So, the elements. We’ve talked about the weather system bringing this to the region, and now it’s time to watch it play out. The cold air hangs on, but temperatures in most locations by the early morning will be above freezing, erasing the late season icing and sleet that was deposited in the hours prior. It will take a little longer to accomplish this in portions of north central MA and southwestern NH where it stayed colder longer, and up to an inch of so of sleet accumulated, along with additional ice accretion. But with the warm air still hanging to the south of the region and riding up over the cold air at the ground we will continue to see plenty of drizzle and periods of rain. As we reach midday and afternoon, the warm air will continue to try getting in while at the same time, low pressure is approaching and pushing a cold front toward the region from the west southwest, lifting that warm air and resulting in a few bands of heavier showers, even possible thunderstorms, that will have to sweep through the region through evening. The timing of these should allow the elite runners to have finished their race, but for those still out on the course they will need to battle through this added element, along with the already chilly and damp conditions, which will include a moderate head wind to cross wind from the east to southeast. In short, this will be one of the harder races to run in, weather-wise, aside from some of the hotter days that have occurred in years gone by. Once all of this is through, we will have to deal with an upper level low pressure area crossing the region from west to east Tuesday, bringing the risk of additional rain showers, especially during the afternoon. At night, it may be cold enough for any additional showers to be in the form of mixed precipitation or snow which could briefly coat things. It’s along shot, but cannot rule it out. Once we get to Wednesday, it’s a quick nice day with high pressure in control before the next low pressure area brings unsettled weather in the form of rain Thursday and leftover rain showers Friday, although the air may be cold enough for some mix with snow in higher elevations well northwest of Boston late Thursday and for a few snow showers to be involved on Friday.

DAYS 6-10 (APRIL 21-25)
High pressure builds in and should give the region fair weather for the April 21-22 weekend. Low pressure to the southwest and south should move up into the region with a chance of rain by April 24 with fair weather returning at the end of the period. Temperatures near to below normal.

DAYS 11-15 (APRIL 26-30)
Some changeable weather at the end of the month as the pattern tries to amplify further, slowing weather systems down. One or 2 sneaky warm days are possible in here but this would not be the start of long-term warming quite yet as Canada remains fairly chilly for some time to come.
