Monday Forecast

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.

Sunday Forecast

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.

Saturday Forecast

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.

Friday Forecast

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.

Thursday Forecast

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.

Wednesday Forecast

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.

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.

Tuesday Forecast

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.

Monday Forecast

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.

Sunday Forecast

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.

Saturday Forecast

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.
