Wednesday Forecast

7:23AM

DAYS 1-5 (MAY 16-20)
The temperature-coaster is rolling along and there is not really any change in the forecast posted yesterday. Thankfully we are by what will be the most threatening weather, yesterday’s thunderstorms, which were quite potent in some locations for this early in the season. So now we’re in the cool air today with a wave of low pressure bringing some afternoon and nighttime rain to at least the South Coast and possibly up to around the Mass Pike, before a sliver of high pressure sinks southward enough to bring a warm-up Thursday, only to be replaced with a new batch of cool air Friday into Saturday, but this time it looks like moisture from the south may push far enough north to soak the entire region by late Friday into Saturday, which is unfortunate if you have outdoor plans for early in the weekend. By Sunday, things should warm back up and we’ll have less wet weather, though still the risk of a shower or thunderstorm, but also more sunshine. So in summary, the weather will be a very good example of mid spring in New England during the next 5 days. Onto the detailed forecast…
TODAY: Mostly cloudy. Afternoon rain South Coast. Highs 55-63. Wind NE 5-15 MPH.
TONIGHT: Cloudy. Rain South Coast to Mass Pike region. Patchy fog. Lows 48-54. Wind light variable.
THURSDAY: Partly sunny. Highs 63-70 South Coast, 70-77 elsewhere. Wind W 5-15 MPH.
THURSDAY NIGHT: Partly cloudy. Lows 52-58. Wind light N to NE.
FRIDAY: Increasing clouds. Chance of rain late. Highs 57-64. Wind NE 5-15 MPH.
SATURDAY: Mostly cloudy. Chance of rain or showers. Lows in the 50s. Highs in the 60s.
SUNDAY: Variably cloudy. Isolated showers/thunderstorms. Lows in the 50s. Highs in the 60s coast, 70s interior.

DAYS 6-10 (MAY 21-25)
The battle of air masses will continue through this period with at least a few opportunities for showers or rain, and variable temperatures.

DAYS 11-15 (MAY 26-30)
High pressure may take over the weather bringing mainly dry weather and above normal temperatures. Never the highest confidence forecast this far in advance with the still-cool ocean and chilly air not that far away in Canada but optimistic at this point.

Tuesday Forecast

7:02AM

DAYS 1-5 (MAY 15-19)
A temperature roller coaster the next several days, but that won’t be the only ride we go on. Today we have a cold front slicing into a warm air mass and this will set the stage for showers and thunderstorms, some of which may be strong to severe. While I’m not expecting a widespread outbreak of severe storms, any of them can be strong and reach severe criteria, so we’ll have to keep a close eye on things this afternoon and early evening, the window of time in which they will be around. High pressure from Canada pushes everything to the south and introduces a much cooler northeasterly flow Wednesday, then sinks to the south and provides a warmer westerly flow on Thursday, only to see the cycle repeat with a cooler Friday, however this time the temperature change will not be accompanied by any thunderstorms. By late Friday into Saturday we will have to watch moisture to the south which may do anything from just glancing the region with rain to moving straight up and giving a significant rainfall. Enjoy the ride the next few days while those late week details get ironed out. Forecast details…
TODAY: Sunshine and passing clouds this morning. Variably cloudy with first isolated to scattered showers and thunderstorms then more general showers and thunderstorms this afternoon and evening, with any thunderstorms possibly strong to locally severe. Becoming humid. Highs 68-76 South Coast, 77-84 elsewhere. Wind SW 10-20 MPH, higher gusts possible.
TONIGHT: Mainly cloudy. Showers and thunderstorms possible early. Areas of fog. Lows 52-58. Wind NW to N up to 10 MPH.
WEDNESDAY: Mostly cloudy to partly sunny. Highs 57-65. Wind NE 5-15 MPH.
WEDNESDAY NIGHT: Partly cloudy. Patchy fog. Lows 48-54. Wind light variable.
THURSDAY: Mostly sunny. Highs 65-72 South Coast, 73-79 elsewhere. Wind W 5-15 MPH.
FRIDAY: Increasing clouds. Chance of rain late. Lows in the 50s. Highs in the 60s.
SATURDAY: Mostly cloudy. Chance of rain or showers. Lows in the 50s. Highs in the 60s.

DAYS 6-10 (MAY 20-24)
The battle of air masses will continue through this period with at least a few opportunities for showers or rain, and variable temperatures. Too early for detailed timing.

DAYS 11-15 (MAY 25-29)
This period should feature less wet weather and a trend to warmer weather.

Monday Forecast

7:24AM

DAYS 1-5 (MAY 14-18)
The warm-up will occur early this week as expected, but don’t expect 2 completely sunny days to go along with it, as today starts with some cloudiness and Tuesday winds up with a shower and thunderstorm threat. This will lead us to an unsettled period of weather mid to late week as the front that is pushing through as a warm front today comes back as a cold front later Tuesday and then sits just south of or over southeastern New England Wednesday through Friday. Forecast details…
TODAY: Variably cloudy into late morning then clearing midday and afternoon. Highs 60-67 coast, 68-75 interior. Wind S to SW up to 10 MPH.
TONIGHT: Partly cloudy. Patchy fog interior valley areas. Lows 52-59. Wind SW up to 10 MPH.
TUESDAY: Partly sunny. Chance of showers and thunderstorms midday through late afternoon, best chance north and west of Boston. Highs 68-75 South Coast, 76-84 elsewhere. Wind SW 10-20 MPH.
WEDNESDAY THROUGH FRIDAY: Mostly cloudy daily. Episodes of showers. Lows in the 50s. Highs in the 60s, coolest coastal areas.

DAYS 6-10 (MAY 19-23)
With the weather pattern likely putting southern New England in a zone between cool Canadian air and warm air from the Mid Atlantic to Southeast US, episodes of unsettled weather are likely, but don’t cancel any plans as there will be stretches of nicer weather amidst it.

DAYS 11-15 (MAY 24-28)
Leaning toward unsettled early period then a drying and warming trend.

Sunday Forecast

11:33AM

Happy Mother’s Day to any mom reading this!

DAYS 1-5 (MAY 13-17)
It’s all about the wind direction, and it doesn’t even have to be a strong wind. Just this light wind off the Atlantic is holding the low level moisture in much of the area, especially coastal NH, eastern MA, RI, and eastern CT. With a little less of this influence to the northwest, interior southern NH and north central MA stand a better chance at seeing a little sun today. By Monday, the wind will turn more to the south and finally the low cloudiness will erode during the day, and by Tuesday it’s a taste of summer across the region with a southwesterly air flow, although this means the South Coast will be cooler. A cold front will approach Tuesday and may set off a few showers and thunderstorms mainly in areas north and west of Boston, and then this boundary will sit around the region at midweek providing an avenue for additional moisture, so we’re looking at an unsettled stretch of weather at that time. Forecast details…
TODAY: Mainly cloudy but partial sun possible north central MA and interior southern NH. Highs 55-60 immediate coast, 60-65 elsewhere. Wind E up to 10 MPH.
TONIGHT: Mostly cloudy. Patchy fog. Lows 46-53. Wind SE under 10 MPH.
MONDAY: Mostly cloudy into late morning then clearing midday and afternoon. Highs 58-65 coast, 66-73 interior. Wind S up to 10 MPH.
MONDAY NIGHT: Partly cloudy. Lows 52-59. Wind SW up to 10 MPH.
TUESDAY: Partly sunny. Chance of showers and thunderstorms midday through late afternoon, best chance north and west of Boston. Highs 68-75 South Coast, 76-84 elsewhere. Wind SW 10-20 MPH.
WEDNESDAY & THURSDAY: Episodes of showers. Lows in the 50s. Highs in the 60s.

DAYS 6-10 (MAY 18-22)
With the weather pattern likely putting southern New England in a zone between cool Canadian air and warm air from the Mid Atlantic to Southeast US, episodes of unsettled weather are likely, but don’t cancel any plans as there will be stretches of nicer weather amidst it.

DAYS 11-15 (MAY 23-27)
With low confidence I say this period is much like the one before it.

Saturday Forecast

8:44AM

DAYS 1-5 (MAY 12-16)
Not a lot of change to the forecast. Today’s the chilly, overcast, and eventually wet day (for most) although the concentration of rain is going to be to the south (CT, RI, southeastern MA) while areas to the north (northern MA and southern NH) have a lighter rain that is of shorter duration. High pressure pushes the wet weather out of here for a dry Mother’s Day Sunday, though clouds will linger especially south. High pressure will continue to sink to the south allowing for fair weather and a warm-up early next week, but by the middle of next week we will find another frontal boundary in the area, separating that warmer air from a new batch of cold air from Canada, and providing the avenue for moisture from the southwest. So a stretch of unsettled weather will get underway at that time.
TODAY: Cloudy. Periods of rain, most widespread midday on southern areas. Highs 48-56. Wind N under 10 MPH becoming E up to 10 MPH.
TONIGHT: Mostly cloudy. Patchy fog. Chance of rain mainly southeastern MA early. Lows 41-47. Wind light variable.
SUNDAY: Partly sunny with more sun likely southern NH and northern MA and less sun to the south. Highs 55-62 coast, 62-68 inland. Wind light variable with coastal sea breezes.
SUNDAY NIGHT: Clearing. Lows 44-52. Wind light variable.
MONDAY: Partly cloudy. Highs in the 58-65 South Coast, 65-72 elsewhere. Wind W 5-15 MPH.
TUESDAY: Mostly sunny. Lows in the 50s. Highs from the middle 60s to lower 70s South Coast, middle 70s to lower 80s elsewhere.
WEDNESDAY: Mostly cloudy. Showers likely. Lows from the middle to upper 50s. Highs in the 60s.

DAYS 6-10 (MAY 17-21)
A frontal boundary is expected to be in the region for a good portion of this period with episodes of unsettled weather, but that doesn’t mean 5 days of rainy weather. It just means that we have some fine tuning to do to time those threats, and figure out temperatures, as we get close.

DAYS 11-15 (MAY 22-26)
Will enter the late portion of May still with some kind of battle between the cool air trying to hang on in Canada and the warmth of the coming summer building to the south. Not quite sure where we end up here in southeastern New England quite yet. Another look at this tomorrow, but still leaning toward at least one potential significant rain event during this time.

Friday Forecast

7:17AM

DAYS 1-5 (MAY 11-15)
A cold front pushes just to the south today which will be a very dry day with a breeze picking up. This leads to high fire danger today, especially across southern NH and northern MA. But rain is on the way and unfortunately it will involve some of the weekend as the front that just went by tries to come back Saturday, and a ripple of low pressure moving along it helps create some rain to pass through the region. This is all expected to push southward again for a drier Mother’s Day Sunday, although some areas may not see complete clearing. Expect high pressure to continue to sink to the south keeping fair weather in place and allowing a warm-up early next week. Details…
TODAY: Early to mid morning cloudiness southern NH and northern MA, mid to late morning cloudiness southern MA and RI / eastern CT, otherwise mainly sunny. Highs 65-72 except cooler Cape Cod / Islands. Wind NW 5-15 MPH with a few higher gusts.
TONIGHT: Increasing clouds. Lows 40-46 most interior areas, 47-53 coast and urban centers. Wind N under 10 MPH.
SATURDAY: Cloudy. Periods of rain. Highs 48-56. Wind N under 10 MPH becoming E up to 10 MPH.
SATURDAY NIGHT: Mostly cloudy. Patchy fog. Lows 41-47. Wind light variable.
SUNDAY: Partly sunny with more sun likely southern NH and northern MA and less sun to the south. Highs 55-62 coast, 62-68 inland. Wind light variable with coastal sea breezes.
MONDAY: Partly cloudy. Lows from the middle 40s to lower 50s. Highs in the 60s, coolest South Coast.
TUESDAY: Mostly sunny. Lows in the 50s. Highs from the middle 60s to lower 70s South Coast, middle 70s to lower 80s elsewhere.

DAYS 6-10 (MAY 16-20)
A frontal boundary is expected to be in the region from the early to middle portion of this period with unsettled weather dominating. High pressure from Canada may push everything to the south and return drier weather to the region later in the period. Temperatures near normal.

DAYS 11-15 (MAY 21-25)
Continued low confidence in the longer range as several potential players are on the table. Leaning toward a dry start and wetter end to this period with temperatures not too far from seasonal averages.

Thursday Forecast

7:14AM

DAYS 1-5 (MAY 10-14)
Continuing to make fine-tuning adjustments on what has been a tough forecast. Marine layer in place today will erode as low pressure offshore moves away and a cold front approaches from the west, bringing a more southerly air flow later, but this front will bring a shower threat this evening before a sliver of high pressure brings nice weather for Friday. But rapidly-moving systems means the front, not far to the south, tries to comes back as a warm front Saturday and makes it only enough for unsettled weather but not really enough to bring warm air in. In fact, the front gets pushed back to the south by high pressure Sunday, although clearing may be delayed for a while so unsure of how much sun appears for Mother’s Day afternoon. The high should push far enough south for fair weather Monday, and somewhat of a warm-up, with coastal areas still vulnerable to typical cooler air. Forecast details…
TODAY: Areas of fog and low clouds giving way to sun then clouds returning from the west late. Highs 60-68 coast, 68-76 elsewhere probably occurring mid to late afternoon. Wind light variable early, then S to SW 5-15 MPH.
TONIGHT: Mostly cloudy. Scattered showers. Lows 50-58. Wind SW 5-15 MPH.
FRIDAY: Mostly sunny. Highs 62-70. Wind NW 5-15 MPH, diminishing late.
FRIDAY NIGHT: Mostly cloudy. Chance of light rain late. Lows 51-58. Wind light variable.
SATURDAY: Mostly cloudy. Chance of rain, favoring morning and midday. Highs 58-65 coast, 65-72 interior. Wind SE to S up to 10 MPH.
SUNDAY: Mostly cloudy with morning showers. Partial clearing afternoon. Lows in the 50s. Highs in the 60s.
MONDAY: Mostly sunny. Lows in the 50s. Highs from the lower to middle 60s coast, upper 60s to middle 70s interior.

DAYS 6-10 (MAY 15-19)
Will again have to watch the position of a frontal boundary during this period as we could end up on either side of it, and also its position determining how many wet weather chances there are. Remaining vague and low confidence at this time.

DAYS 11-15 (MAY 20-24)
Still uncertain in the pattern here as well, but leaning toward a risk of some wetter weather at some point, favoring late in the period.

Wednesday Forecast

1:52AM

DAYS 1-5 (MAY 9-13)
A few adjustments to the forecast for this period. First, high pressure remains in control today with again the coast being cooler, typical for springtime. Last week, medium range guidance showed the potential for a low pressure area impacting the East Coast around May 9. Turns out this model forecast was somewhat correct, as an area of low pressure offshore, moving northward, will be close enough to drag an area of rain through Nantucket and the outer part of Cape Cod tonight, but it will be quickly gone by early Thursday as a cold front approaches the region from the west. This front will cross Thursday night when a shower risk exists. Our quickly changing weather continues with high pressure building in Friday or a nice day. Things are starting to come into focus a little more for the weekend. It looks like the front that went through Thursday night, sitting just to the south through Friday, will come back as a warm front Saturday, preceded by a period of rain, then pushing north enough to allow some milder and more humid air in, but this won’t last either, as the front quickly pushes back to the south with another period of wet weather early Sunday, but high pressure should then push the front further south and move in for a nicer finish to Mother’s Day. Forecast details…
TODAY: Foggy start across southern RI and southeastern MA, and portions of northeastern MA and coastal NH, otherwise mostly sunny. Highs 58-66 coastal areas, 67-74 interior areas. Wind light variable with sea breezes.
TONIGHT: Mostly cloudy. A period of rain outer Cape Cod and Nantucket. Lows 48-55. Wind light variable except N 10-20 MPH Cape Cod and Nantucket.
THURSDAY: Mostly sunny morning. Increasing clouds afternoon. Highs 60-68 coast, 68-76 elsewhere. Wind S to SW 5-15 MPH.
THURSDAY NIGHT: Mostly cloudy. Scattered showers. Lows 50-58. Wind SW 5-15 MPH.
FRIDAY: Mostly sunny. Highs 62-70. Wind NW 10-20 MPH, diminishing late.
SATURDAY: Mostly cloudy. Chance of rain, favoring morning and midday. Becoming humid. Lows in the 50s. Highs in the 60s.
SUNDAY: Mostly cloudy with morning showers. Clearing afternoon. Lows in the 50s. Highs in the 60s.

DAYS 6-10 (MAY 14-18)
High pressure sinks to the south for fair and warmer weather May 14-15 before a stretch of unsettled weather arrives during the middle to end of the period with a front in the vicinity.

DAYS 11-15 (MAY 19-23)
Leaning away from the omega block idea for now but we do have to watch for more unsettled weather anyway with high pressure in Canada and a frontal boundary near or south of the region for at least a portion of this period.

Tuesday Forecast

7:29AM

DAYS 1-5 (MAY 8-12)
Weak high pressure over southern New England and weak low pressure just to the south today and Wednesday. The biggest impact of this set up will be some morning fog today, areas of low clouds at times along the coast, and also cooler air along the coast. Still looking for a cold front to pass by Thursday night and early Friday and settle not too far south of the region Saturday, which may end up somewhat unsettled. Detailed forecast…
TODAY: Areas of fog early to mid morning. Coastal clouds at times, sun otherwise. Highs 60-67, cooler coast. Wind light E to SE.
TONIGHT: Variably cloudy. Patchy fog. Lows 46-53. Wind light variable.
WEDNESDAY: Mostly sunny but some clouds may linger coastal areas especially Cape Cod. Highs 60-67 immediate coast, 68-75 elsewhere. Wind light variable with coastal sea breezes.
THURSDAY: Sunshine, clouds late, risk of showers at night. Lows from the lower to middle 50s. Highs from the lower 60s South Coast to upper 60s to lower 70s elsewhere.
FRIDAY: Early clouds and possibly a shower then more sun and breezy. Lows from the middle to upper 50s. Highs in the 60s.
SATURDAY: Variably cloudy. Risk of showers. Lows from the upper 40s to middle 50s. Highs in the 60s.

DAYS 6-10 (MAY 13-17)
Still some uncertainly about the weather for May 13 but leaning toward clouds and possible damp weather with a brief warm up following this for May 14 then more seasonably mild weather interior and cooler weather coast for the middle of next week and mostly fair conditions. However always must watch this pattern for low clouds in coastal areas at this time of year. This continues to be a low confidence forecast.

DAYS 11-15 (MAY 18-22)
Still watching for the possibility of an omega block to set up which could put the region into several days of unsettled weather. This is also low confidence and not unusual for trying to look ahead and upcoming weather in the spring.

Monday Forecast

7:15AM

DAYS 1-5 (MAY 7-11)
High pressure builds in today through some leftover low level moisture will result in early fog for parts of the region and then a sun/cloud mix as the ground heats and the moisture rises into cooler air during the day. Still have to watch a low to the south Tuesday in case it is close enough to spread more cloudiness into the region as high pressure tries to hold it off. High pressure will take more control by Wednesday with nice weather before a cold front approaches late Thursday and passes through early Friday with most of the shower activity expected Thursday night with the front. Detailed forecast…
TODAY: Areas of fog early otherwise a cloud/sun mix. Highs 58-65, cooler coast. Wind light variable becoming NE up to 10 MPH.
TONIGHT: Mostly clear. Patchy fog in low-lying areas. Lows 38-45 most interior areas, 45-52 coastal and urban centers. Wind calm.
TUESDAY: Partly sunny north, mostly cloudy south. Highs 60-67, cooler coast. Wind light E to SE.
TUESDAY NIGHT: Variably cloudy. Lows 46-53. Wind light variable.
WEDNESDAY: Mostly sunny. Highs 60-67 immediate coast, 68-75 elsewhere. Wind light variable with coastal sea breezes.
THURSDAY: Sunshine, clouds late, risk of showers at night. Lows from the lower to middle 50s. Highs from the lower 60s South Coast to upper 60s to lower 70s elsewhere.
FRIDAY: Early clouds and possibly a shower then more sun and breezy. Lows from the middle to upper 50s. Highs in the 60s.

DAYS 6-10 (MAY 12-16)
The May 12-13 weekend is uncertain but will probably be somewhat unsettled. What is most uncertain is timing and position of frontal boundaries in the area, so will need to figure that out in the next few days. The leaning is toward fair weather for Saturday May 12 with a front still far enough south and damp/cool weather Sunday May 13 as it moves into the region as a warm front. This timing would probably lead to a shot of warm air about May 14 then a trend back to cooler again May 15-16. Again, highly uncertain and low confidence forecast period.

DAYS 11-15 (MAY 17-21)
Still watching for the possibility of an omega block to set up which could put the region into several days of unsettled weather. This is also low confidence and not unusual for trying to look ahead and upcoming weather in the spring.

Sunday Forecast

7:01AM

DAYS 1-5 (MAY 6-10)
Two northeastward-moving low pressure areas, one tracking from PA to southeastern Canada, the other passing offshore southeast of New England, will bring a cloudy, cooler, and occasionally wet day today, though many areas may escape rainfall for much of the day. Most of this will exit by early Monday, but some cloudiness may linger, and we’ll have to watch another wave of low pressure to the south that may end up close enough for some additional cloudiness at least and possibly a wet weather threat again at some point on Tuesday. Expecting high pressure to overtake the region with drier weather at midweek.
TODAY: Cloudy. A few periods of rain possible. Highs 58-65. Wind light variable.
TONIGHT: Mostly cloudy. Lows 48-55. Wind light variable.
MONDAY: Variably cloudy. A risk of light rain mainly Cape Cod early. Highs 60-66. Wind light variable.
MONDAY NIGHT: Variably cloudy. Lows 46-53. Wind light variable becoming SE.
TUESDAY: Mostly cloudy. Chance of rain favoring the South Coast. Highs 60-67. Wind light SE to E.
WEDNESDAY: Mostly sunny. Lows in the 40s. Highs in the 60s.
THURSDAY: Partly cloudy. Lows from the upper 40s to lower 50s. Highs from the middle 60s to lower 70s.

DAYS 6-10 (MAY 11-15)
A cold front may bring a few rain showers May 11 followed by a dry May 12-13 weekend with a cool start and a warmer finish. A trough west of the region and high pressure offshore allow warmer air for May 14-15 but eventually the chance of some showers.

DAYS 11-15 (MAY 16-20)
Low confidence forecast, but there is the possibility an omega block develops during this period with low pressure nearby to New England. this would result in a trend toward unsettled weather for a few days with a system that doesn’t move much.

Saturday Forecast

1:47AM

DAYS 1-5 (MAY 5-9)
After things working out as expected on Friday (a warm, humid day, morning and midday showers, storms dying before they made it too far east, and gusty winds surviving the trip) we now move onto the weekend. And we basically have a split of sorts with dry weather but some cloudiness today and a wave of low pressure bringing a general overcast with a risk of some rain on Sunday as it passes by to the southeast. The boundary it rides along will still be fairly close by and cloudiness may even linger Monday before high pressure finally pushes in with more sun for Tuesday and Wednesday.
TODAY: Many clouds but thin enough for some sun. Highs 67-74. Wind W 10-20 MPH with higher gusts early, diminishing slowly.
TONIGHT: Mostly cloudy. Lows 48-55. Wind light SW to S.
SUNDAY: Cloudy. A few periods of rain possible. Highs 58-65. Wind light variable.
SUNDAY NIGHT: Mostly cloudy. Lows 48-55. Wind light variable.
MONDAY: Variably cloudy. Highs 60-66. Wind light variable.
TUESDAY: Mostly sunny. Lows in the 40s. Highs in the 60s.
WEDNESDAY: Mostly sunny. Lows in the 40s. Highs in the 60s.

DAYS 6-10 (MAY 10-14)
A front should pass through the region sometime from later May 10 to May 11 with the risk of some showers, followed by fair weather, a brief cool shot, then a warm-up.

DAYS 11-15 (MAY 15-19)
Low confidence forecast, but there is the possibility an omega block develops during this period with low pressure nearby to New England. this would result in a trend toward unsettled weather for a few days with a system that doesn’t move much.

Friday Forecast

6:58AM

DAYS 1-5 (MAY 4-8)
We remain in the warm, summer-like air mass for one more day until a cold front crosses the region tonight. There will be a threat of showers and a few thunderstorms today, but the severity of any storms should be limited by abundant cloud-cover through midday, then the risk of storms should be muted by drying air by the time the actual front arrives this evening. A brief shot of northwesterly flow at the surface will cool it down as the weekend arrives, but the front that goes by is never going to get very far to the southeast of the region, and will serve as the running board for some additional cloudiness on Saturday and eventually some areas of rain Sunday as a wave of low pressure moves up along the front, passing southeast of the region. High pressure will finally push it all further south early next week. Forecast details…
TODAY: Mostly cloudy through midday with a couple episodes of showers and possibly a thunderstorm. Partly sunny remainder of day with isolated showers and possible thunderstorms. Humid. Highs 68-76 South Coast, 77-86 elsewhere. Wind SW increasing to 10-20 MPH and gusty.
TONIGHT: Partly cloudy. Slight risk of a passing shower or thunderstorm evening. Lows 53-59. Wind SW to W 10-20 MPH with higher gusts.
SATURDAY: Partly sunny. Highs 66-72 Cape Cod, 72-77 elsewhere. Wind W 15-25 MPH morning, diminishing afternoon.
SATURDAY NIGHT: Mostly cloudy. Lows 51-57. Wind W to SW up to 10 MPH.
SUNDAY: Cloudy. Periods of light rain possible. Highs 62-68. Wind S to SE up to 10 MPH.
MONDAY: Partly cloudy. Lows from the upper 40s to lower 50s. Highs in the 60s.
TUESDAY: Mostly sunny. Lows in the 40s. Highs in the 60s.

DAYS 6-10 (MAY 9-13)
First half of period runs risk of unsettled weather due to a combination of low pressure from the south and a front from the northwest. Later period should feature fair weather with high pressure moving in. This particular period of forecast is low confidence at this time.

DAYS 11-15 (MAY 14-18)
If the 6-10 day period goes as expected, this period could start with a brief shot of very warm air, a shower/thunderstorm threat, then a turn to more seasonable weather.

Thursday Forecast

7:01AM

DAYS 1-5 (MAY 3-7)
A surface front will approach from the northwest today then situate itself so it sits just north of the region through most of Friday before pushing to the south to just south of New England during Saturday before stopping there for the remainder of this period. A couple waves of low pressure will ripple along this front during the next several days. While we’re on its warm side, we’ll have the chance of showers and thunderstorms from this afternoon through Friday night. On its cooler side, a few periods of rain are possible during Sunday. A weak area of high pressure will move in by Monday but a front still not far to the south and weak trough in the upper atmosphere will keep cloudiness around. Forecast details…
TODAY: Variably cloudy. Isolated to scattered showers and thunderstorms this afternoon. Any thunderstorms may be capable of producing damaging wind gusts. More humid. Highs 68-76 South Coast, 77-85 elsewhere. Wind W 5-15 MPH with higher gusts.
TONIGHT: Variably cloudy. Isolated showers and thunderstorms. Patchy fog. Humid. Lows 58-66. Wind W 5-15 MPH.
FRIDAY: Mostly cloudy. Isolated to scattered showers and possible thunderstorms. Humid. Highs 67-75 South Coast, 76-82 elsewhere. Wind SW 10-20 MPH with higher gusts.
FRIDAY NIGHT: Mostly cloudy. Chance of showers and thunderstorms in the evening. Humid evening, drier overnight. Lows 55-62. Wind SW 5-15 MPH with higher gusts, shifting to WNW.
SATURDAY: Mostly cloudy to partly sunny. Highs 66-74. Wind W 5-15 MPH.
SUNDAY: Mostly cloudy. Chance of light rain. Lows in the 50s. Highs in the 60s.
MONDAY: Variably cloudy. Lows in the 50s. Highs in the 60s.

DAYS 6-10 (MAY 8-12)
High pressure should bring mainly dry weather to the region May 8-9, then a couple weak disturbances and a front passing through the area should bring a few episodes of showers in the May 10-12 time frame. Temperatures variable but averaging around normal for the period.

DAYS 11-15 (MAY 13-17)
Brief wet weather may start this period before nicer mid spring weather arrives and a cool start turns into a warmer mid to late period.

Wednesday Forecast

2:00AM

DAYS 1-5 (MAY 2-6)
A ridge of high pressure along the East Coast brings that well-advertised summer preview for the next few days, but today will be the only day without any threat of unsettled weather as a cold front approaching later Thursday may trigger a few showers and thunderstorms, with this chance to increase even more Friday as the front moves into the region. However this front will be slow to push through and will take until early Saturday to do so, and then it will probably hang up near or just south of the South Coast, with no complete clearing right through the coming weekend. So far not expecting much of any rainfall, however, though we must always watch this set-up for sneaky rain. Forecast details…

DAYS 6-10 (MAY 7-11)
A front hanging in the region early in the period (May 7-8) will bring the chance for some additional unsettled weather to the region. After that, high pressure should take over with fair weather in the May 9-11 time frame. Temperatures near to slightly above normal.

DAYS 11-15 (MAY 12-16)
A cold front should bring some unsettled weather early in the period followed by a cool-down. There are some hits of the evolution of an omega block trying to get established toward the end of the period in which an upper level low may be situation somewhere near the East Coast. This may increase the risk of unsettled weather in the region.
