8:10AM

DAYS 1-5 (MAY 20-24)
No changes so just a quick update. In the warm sector for a while today but a cold front brings a shower or thunderstorm to parts of the region this afternoon. Not cooling down much but just drying out for Monday. A bit cooler still Tuesday when a disturbance may bring showers. Fair weather returns midweek. Still watching a weak system for Thursday but that may end up as just a passing cloud event.
Detailed forecast…
TODAY: Mostly cloudy to partly sunny morning. Variably cloudy with passing showers and thunderstorms possible afternoon. Humid. Highs 65-72 coast, 72-78 interior. Wind SW 10-20 MPH, shifting to W late.
TONIGHT: Partly cloudy. Less humid. Lows 52-58. Wind W shifting to NW 5-15 MPH.
MONDAY: Mostly sunny. Highs 68-73 South Coast, 74-79 elsewhere. Wind W 5-15 MPH.
TUESDAY: Mostly cloudy. Chance of showers. Lows from the middle to upper 50s. Highs from the middle to upper 60s.
WEDNESDAY: Mostly sunny. Lows from the lower to middle 50s. Highs from the upper 60s to lower 70s coast, middle to upper 70s interior.
THURSDAY: Variably cloudy. Lows from the middle to upper 50s. Highs from the middle 60s to lower 70s.

DAYS 6-10 (MAY 25-29)
Not really making any changes here. This period we will have to watch tropical moisture to the south and a frontal boundary to the north. If both stay generally away it’s fairly dry and warmer than normal, but that may not be the case, so much refinement coming in future updates.

DAYS 11-15 (MAY 30-JUNE 3)
Unsettled weather is possible to end May then a period of fair weather expected to start June. Temperatures near to slightly above normal but there may be a cooler period especially in coastal locations.

8:52AM

DAYS 1-5 (MAY 19-23)
A warm front approaches today and eventually brings wet weather to the region from southwest to northeast. As its parent low passes north of New England on its eastward path, it will drag a cold front through the region on Sunday with some additional shower activity expected. High pressure builds in for a nice late May day on Monday before the next disturbance returns a chance of some wet weather by Tuesday. Detailed forecast…
TODAY: Thickening overcast. Rain arriving southwest to northeast late morning through mid afternoon then tapering to drizzle/showers late. Highs 55-60 coast, 60-65 interior. Wind E 5-15 MPH.
TONIGHT: Mostly cloudy. Areas of fog. Patchy drizzle and isolated showers. Lows 53-58 early then temperatures slowly rising to 60-65 late. Wind shifting to S then SW up to 10 MPH.
SUNDAY: Mostly cloudy with patchy fog and isolated showers morning. Partly sunny with passing showers and thunderstorms possible afternoon. Humid. Highs 65-72 coast, 72-78 interior. Wind SW 10-20 MPH, shifting to W late.
SUNDAY NIGHT: Partly cloudy. Less humid. Lows 52-58. Wind W shifting to NW 5-15 MPH.
MONDAY: Mostly sunny. Highs 68-73 South Coast, 74-79 elsewhere. Wind W 5-15 MPH.
TUESDAY: Mostly cloudy. Chance of showers. Lows from the middle to upper 50s. Highs from the middle to upper 60s.
WEDNESDAY: Mostly sunny. Lows from the lower to middle 50s. Highs from the upper 60s to middle 70s.

DAYS 6-10 (MAY 24-28)
A disturbance passes through with a shower threat May 24 and a front may linger in the area with isolated showers into May 25. A generally dry and warmer Memorial Day Weekend is the early call but will have to watch 2 things that can complicate the forecast, and those are a front that may approach from the north later in the weekend and tropical moisture that may approach from the south by about Memorial Day. This being quite distant, forecast-wise, there is plenty of time to fine-tune this forecast.

DAYS 11-15 (MAY 29-JUNE 2)
A little more unsettled with a front and a couple disturbances in the area the last few days of May before fair weather becomes more likely to start June. Temperatures near to slightly above normal but there may be a cooler period especially in coastal locations.

7:33AM

DAYS 1-5 (MAY 18-22)
No big changes from yesterday’s, just minor tweaks. The onshore flow is back today with cool air and dominant cloudiness. A warm front approaches and eventually passes Saturday but a period of rain will accompany it. A cold front crosses the region during Sunday bringing the chance of showers. Not all of the weekend will be washed out, but it will be far from stellar. High pressure arrives with fair weather Monday before the next disturbance brings a chance of showers by Tuesday.
TODAY: Mostly cloudy. Highs 57-64. Wind NE 5-15 MPH.
TONIGHT: Cloudy. Lows 50-56. Wind NE to E up to 10 MPH.
SATURDAY: Cloudy. Periods of rain, mostly mid morning to mid afternoon. Highs 55-63, coolest coast. Wind E to SE up to 15 MPH.
SUNDAY: Variably cloudy. Scattered showers/thunderstorms. Lows in the 50s. Highs in the 60s coast, 70s interior.
MONDAY: Mostly sunny. Lows in the 50s. Highs in the 70s.
TUESDAY: Mostly cloudy. Chance of showers. Lows in the 50s. Highs in the 60s.

DAYS 6-10 (MAY 23-27)
Fair weather expected May 23. Another disturbance brings the next rain or shower chance about May 24 then it looks drier and warmer for the middle to end of this period.

DAYS 11-15 (MAY 28-JUNE 1)
Fair/warm weather expected early in the period, then a shower/thunderstorm threat increases to end May before fair weather returns at the end of the period.

7:32AM

DAYS 1-5 (MAY 17-21)
Clouds will be the dominant feature in the weather through the weekend though the daily weather and temperature will still be variable. Today’s one of the warmer days before cooler air returns Friday, but these days will be generally dry. It’s Saturday that still looks like the wettest as some tropical moisture from the south pushes northward, initially riding up and over the cooler air at the surface. It warms again by Sunday but this day will also have its chance of some wet weather, though very likely will be the better of the 2 weekend days. High pressure overtakes the weather by Monday with better conditions. Detailed forecast…
TODAY: Mostly cloudy. Highs 63-70 South Coast, 70-77 elsewhere. Wind W 5-15 MPH.
TONIGHT: Mostly cloudy. Lows 52-58. Wind light N to NE.
FRIDAY: Mostly cloudy. Highs 57-64. Wind NE 5-15 MPH.
FRIDAY NIGHT: Cloudy. Lows 50-56. Wind NE to E up to 10 MPH.
SATURDAY: Cloudy. Periods of rain. Highs 55-63, coolest coast. Wind E to SE up to 15 MPH.
SUNDAY: Variably cloudy. Scattered showers/thunderstorms. Lows in the 50s. Highs in the 60s coast, 70s interior.
MONDAY: Mostly sunny. Lows in the 50s. Highs in the 70s.

DAYS 6-10 (MAY 22-26)
More weather changes, with a fair/warmer start to the period, a disturb ance bringing a chance of showers or rain followed by cooler weather during the middle of the period, and the start of a warm up with fair weather by the end of the period.

DAYS 11-15 (MAY 27-31)
High pressure may take over the weather bringing mainly dry weather and above normal temperatures through the middle of the period but an increase in showers/thunderstorms possible toward the last couple days of the month.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
