DAYS 1-5 (JUNE 6-10)
The frontal boundary that has been sitting in our area for the last couple days divides cooler air in southern NH and northern MA from warm and humid air to the south, and this boundary will slowly sink to the south today, being the focus for some additional showers and thunderstorms, although these will get less numerous and more isolated as the day goes on and drier air works in from north to south. This boundary will be close enough for some potential cloudiness at times into Friday but high pressure building toward the region from Canada will assure dry weather and this high will bring a fabulous June weekend. By Monday, an approaching warm front returns cloudiness to the region.
Forecast details…
TODAY: Mostly cloudy. Scattered to isolated showers and thunderstorms. Humid, especially southern areas, but slowly drying north to south.
Highs 68-75. Wind variable, shifting from SW to N from north to south, 5-15 MPH.
TONIGHT: Partly cloudy. Lows 53-60. Wind light N.
FRIDAY: Partly sunny. Highs 71-78. Wind light N.
FRIDAY NIGHT: Mostly clear. Lows 48-53 interior, coolest valleys, 53-58 elsewhere. Wind light variable.
SATURDAY: Mostly sunny. Highs 71-78, but cooling back to upper 60s coast afternoon. Wind light variable to NW but coastal sea breezes.
SATURDAY NIGHT: Mostly clear. Lows 50-57. Wind light variable.
SUNDAY: Mostly sunny. Highs 77-84, cooler in some coastal areas especially Cape Cod. Wind variable to W 5-15 MPH.
SUNDAY NIGHT: Mostly clear. Lows 52-59. Wind W up to 10 MPH.
MONDAY: Increasing clouds. Highs 73-80, coolest coast. Wind light variable to SE.

DAYS 6-10 (JUNE 11-15)
Cold front crosses the region June 11 with showers/thunderstorms. High pressure brings fair weather June 12. Low pressure passes southeast of or over the region June 13 with a rain threat. Fair and seasonable weather for the end of the period.

DAYS 11-15 (JUNE 16-20)
A generally zonal (west to east) jet stream pattern with mean ridge of high pressure centered west of New England. This pattern sends a few chances of showers/thunderstorms this way but also brings fair and seasonably warm weather in between.

7:21AM

DAYS 1-5 (JUNE 5-9)
A frontal boundary will sit across northern MA and southern NH today into Thursday, and may waver around a little playing havoc with the temperatures near it. This front will also be the running board for a few showers and possible thunderstorms during today, which will become more frequent tonight into Thursday, before the front pushes to the south as low pressure moves along it then to our northeast. Thursday night into Friday a push of drier air gets the wet weather out of here and replaces it with fair weather, setting up a great weekend with high pressure in control of the weather.
Forecast details…
TODAY: Mostly cloudy. Isolated to scattered showers and a slight risk of thunderstorms, favoring southern NH and northern MA. Highs 60-67 north, 68-75 south. Wind N 5-15 MPH northern areas, SW 5-15 MPH but higher gusts central and southern areas.
TONIGHT: Mostly cloudy. Showers likely. Chance of thunderstorms. Humid. Lows 60-67. Wind variable, mostly SW in southern areas, 5-15 MPH with higher gusts.
THURSDAY: Mostly cloudy. Showers likely. Chance of thunderstorms. Humid. Highs 68-75. Wind S to SW 10-20 MPH.
THURSDAY NIGHT: Mostly cloudy. Showers ending. Less humid late. Lows 55-62. Wind W 5-15 MPH.
FRIDAY: Partly sunny. Highs 71-78. Wind W 5-15 MPH.
FRIDAY NIGHT: Mostly clear. Lows 48-53 interior, coolest valleys, 53-58 elsewhere. Wind light variable.
SATURDAY: Mostly sunny. Highs 71-78, but cooling back to upper 60s coast afternoon. Wind light variable to NW but coastal sea breezes.
SUNDAY: Mostly sunny. Highs 77-84, cooler in some coastal areas especially Cape Cod. Wind variable to W 5-15 MPH.

DAYS 6-10 (JUNE 10-14)
Warm start to period then a cooling trend. Unsettled weather days are most likely to be June 11 with a cold front and June 13 with another low pressure area passing through the region. Other days mainly dry.

DAYS 11-15 (JUNE 15-19)
A generally zonal (west to east) jet stream pattern with mean ridge of high pressure centered west of New England. This pattern sends a few chances of showers/thunderstorms this way but also brings fair and seasonably warm weather in between.

7:11AM

DAYS 1-5 (JUNE 4-8)
High pressure hangs on with nice weather to start today then clouds move in ahead of a warm front, but rain holds off until later tonight, and will favor northern MA northward as the front moves into the region but has trouble pushing too far to the north on Wednesday, a day in which temperatures may range quite widely from north to south across the region. The front will remain in the vicinity as a wave of low pressure moves along it, bringing more widespread showers Wednesday night and Thursday. All of it pushes offshore and high pressure moves in with improving weather to end the week, though the front will be sluggish to move along at first so clouds may linger on Friday.
Forecast details…
TODAY: Sun then increasing clouds. Highs 62-69. Wind light SE.
TONIGHT: Cloudy. Periods of rain late evening and overnight, mainly north of I-90. Lows 50-57. Wind light variable.
WEDNESDAY: Mostly cloudy. Rain ends north early. Showers arrive west to east evening. More humid. Highs 58-65 north, 65-72 south, but possibly a 72-79 area interior eastern CT or far southern MA. Wind light variable, mostly N to E in southern NH and northern MA, and mostly S to SW in southern MA, CT, and RI.
WEDNESDAY NIGHT: Mostly cloudy. Showers likely. Chance of a thunderstorm. Humid. Lows 60-67. Wind light variable.
THURSDAY: Variably cloudy. Chance of showers, possible thunderstorms. Humid. Highs 73-80. Wind S 5-15 MPH.
THURSDAY NIGHT: Mostly cloudy. Showers ending. Less humid late. Lows 55-62. Wind W 5-15 MPH.
FRIDAY: Variably cloudy. Highs 71-78. Wind W 5-15 MPH.
FRIDAY NIGHT: Mostly clear. Lows 48-53 interior, coolest valleys, 53-58 elsewhere. Wind light variable.
SATURDAY: Mostly sunny. Highs 71-78, but cooling back to upper 60s coast afternoon. Wind light variable to NW but coastal sea breezes.

DAYS 6-10 (JUNE 9-13)
High pressure controls with fair weather to start the period, but the overall pattern being similar with trough eastern Canada and ridge Great Lakes / Midwest, will send a couple disturbances through the area with shower and thunderstorm threats, variable but overall seasonable temperatures and a lack of early heat.

DAYS 11-15 (JUNE 14-19)
Gradual transition toward a more zonal pattern, but overall result similar here to the pattern during the 6-10 day period.

7:38AM

DAYS 1-5 (JUNE 3-7)
Things are a little flatter and faster in the atmosphere, so we can back off on the instability showers and add more sun to today’s forecast, keep one very cool night under high pressure tonight, get rid of the upper level cool pool for Tuesday and bring an approaching warm front and its increasing clouds into the forecast, wet weather with the front Tuesday night, and get the region into the warm sector, but still near the front, Wednesday into Thursday, when another round of showers and possible thunderstorms can occur Wednesday night into Thursday. By late in the week we should have high pressure over us with the front sufficiently to the south to keep it dry, but may not to keep cloudiness out of the region, so that’s the end of the week wildcard now.
Forecast details…
TODAY: Sun and passing clouds. Highs 63-70. Wind NW 10-20 MPH.
TONIGHT: Mostly clear. Lows 43-50. Wind becoming light variable.
TUESDAY: Sun then increasing clouds. Highs 62-69. Wind light SE.
TUESDAY NIGHT: Cloudy. Periods of rain. Lows 50-57. Wind light variable.
WEDNESDAY: Mostly cloudy. Rain ends early. Showers arrive late. More humid. Highs 69-76. Wind light S.
WEDNESDAY NIGHT: Mostly cloudy. Showers likely. Humid. Lows 60-67. Wind light S.
THURSDAY: Variably cloudy. Chance of showers, possible thunderstorms. Humid. Highs 73-80. Wind S 5-15 MPH.
THURSDAY NIGHT: Mostly cloudy. Showers ending. Less humid late. Lows 55-62. Wind W 5-15 MPH.
FRIDAY: Variably cloudy. Highs 71-78. Wind W 5-15 MPH.

DAYS 6-10 (JUNE 8-12)
June 8-9 weekend looks fair and seasonable at this time with a front far enough to the south and low pressure over eastern Canada while high pressure sits over the Great Lakes. Overall pattern stays somewhat like this but disturbances can move along the northwest flow into New England early to middle part of next week.

DAYS 11-15 (JUNE 13-17)
Still no major pattern shifts seen, similar to the 6-10 day period.

7:33AM

DAYS 1-5 (JUNE 2-6)
Yesterday morning it was the high altitude smoke, this morning it is the low stuff (fog, low clouds), and it will take a while to burn it off where it is because there is cloudiness above taking a bite out of the sun’s power this morning. But a good thing, especially with so much planned outside, is that we won’t have a rainy day today. Other than some patchy light drizzle within the foggy areas the first part of the morning, and the remote risk of a pop up shower later this morning as we start to transition out of the marine air, it’ll be a rain-free day, with showers holding off until later this evening and tonight from a cold front moving across the region. An upper level cool pool will still trigger the risk of a few instability showers Monday but this threat looks less for Tuesday as it should move out more quickly. But a warm front may bring a few showers to the region Tuesday night and lead to a much warmer day Wednesday with high pressure centered south of the region. A weak cold front in the vicinity on Thursday may trigger a few showers and thunderstorms.
Forecast details…
TODAY: Fog/low clouds dominant with patchy light drizzle through mid morning, then mostly cloudy to partly sunny remainder of the day with no more than an isolated shower late morning. Highs 63-68 coastline, 68-73 elsewhere. Wind light variable to SE.
TONIGHT: Cloudy. Showers and a risk of a thunderstorm southwestern NH, central MA, eastern CT, and a risk of showers further east. Lows 55-62. Wind light variable.
MONDAY: Partly sunny. Isolated to scattered showers, mainly afternoon and early evening. Highs 63-70. Wind N 5-15 MPH, higher gusts.
MONDAY NIGHT: Variably cloudy. Scattered showers possible early. Lows 50-57. Wind NW 5-15 MPH, higher gusts.
TUESDAY: Partly cloudy. Highs 65-72. Wind W 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Chance of showers. Lows 51-58. Wind light variable.
WEDNESDAY: Mostly sunny. Highs 75-82, cooler Cape Cod. Wind SW 10-20 MPH.
WEDNESDAY NIGHT: Partly cloudy. Lows 56-63. Wind SW 5-15 MPH.
THURSDAY: Partly sunny. Isolated showers and thunderstorms possible. Highs 77-84, cooler South Coast. Wind SW to S 5-15 MPH becoming variable.

DAYS 6-10 (JUNE 7-11)
The large scale pattern will be similar to the current one, mean trough position in eastern Canada with a ridge to the west (Midwest / Great Lakes). This pattern will send disturbances southeastward across New England and bring a few opportunities for showers. Temperatures, while somewhat variable, will average fairly close to seasonal normals overall. Some guidance wants to bring a shot of very warm to hot air in near the end of this period but holding off on going with that for now.

DAYS 11-15 (JUNE 12-16)
Still holding with the same general pattern but watching for a quick switch to hotter for a day or 2. There is some uncertainty still.

9:21AM

DAYS 1-5 (JUNE 1-5)
Hello June! May went out with a smoke show as high altitude smoke from Canadian forest fires made for fairly rare conditions for filtered sun that was orange to red far higher in the sky than you’d normally see, and the sun even vanished from site before it set, despite lack of clouds. Our first sunrise of June was the same as the smoke lingers. We may not see the same thing repeat this evening, as there will be more cloudiness – both low clouds near coastal areas and higher clouds from the west. Those clouds from the west will be associated with showers and thunderstorms that may make it as far east as the Connecticut River Valley before expiring due to stable air they will be running into. I’d be surprised if a remnant shower made it anywhere close to the coast overnight. Sunday will be a slightly more pronounced repeat of today, in which the showers and storms may make a better run into eastern areas during the evening as they fall apart, but again look for generally dry weather for the great majority of the time, which is good news for many outdoor graduation ceremonies taking place. At one point I was worried that it would turn quite wet around here Sunday afternoon. That is no longer the case. As we start the new week, a cool pool of air above us will result in the typical instability clouds and possible pop up showers Monday and Tuesday, before it gets far enough east for high pressure to build in for a nice Wednesday, and the center passing south of the region should provide a general land breeze (except Cape Cod) and a fairly quick warm-up for most of the region.
Forecast details…
TODAY: Smoke-filtered sun, eventually more clouds. Coastal areas may be in and out of fog/low clouds. Highs 65-70 coast, 70-75 interior. Wind light E to SE.
TONIGHT: Mostly cloudy. A shower or thunderstorms may reach southwestern NH, central MA, and eastern CT late evening and a slight risk of a stray shower further east overnight. Areas of fog, especially coast. Lows 55-62. Wind light SE to S.
SUNDAY: Areas of low clouds and fog early to mid morning, then partly sunny later morning into afternoon except areas of fog may linger near the South Coast. Increasing clouds west to east later. Highs 63-68 coastline, 68-73 elsewhere. Wind light variable.
SUNDAY NIGHT: Cloudy. Showers and a risk of a thunderstorm southwestern NH, central MA, eastern CT, and a risk of showers further east. Lows 55-62. Wind light variable.
MONDAY: Partly sunny. Isolated to scattered showers, mainly afternoon and early evening. Highs 63-70. Wind N 5-15 MPH, higher gusts.
MONDAY NIGHT: Variably cloudy. Scattered showers possible early. Lows 50-57. Wind N 5-15 MPH, higher gusts.
TUESDAY: Partly sunny. Isolated showers possible. Highs 64-71. Wind NW 10-20 MPH, higher gusts possible morning, W 5-15 MPH afternoon.
TUESDAY NIGHT: Clearing. Lows 48-55. Wind light W.
WEDNESDAY: Mostly sunny. Highs 75-82, cooler Cape Cod. Wind WSW 5-15 MPH.

DAYS 6-10 (JUNE 6-10)
The large scale pattern will be similar to the current one, mean trough position in eastern Canada with a ridge to the west (Midwest / Great Lakes). This pattern will send disturbances southeastward across New England and bring a few opportunities for showers. Temperatures, while somewhat variable, will average fairly close to seasonal normals overall.

DAYS 11-15 (JUNE 11-15)
Same general idea as previously with pattern persistence. Not comfortable forecasting any significant changes at this time, although one of the more reliable medium ranges models does turn it hotter rather quickly. Could that be the quick pattern shift I have referred to? I’m not confident enough to go with it yet.

6:58AM

DAYS 1-5 (MAY 31-JUNE 4)
Patterns can be unsettled and not overly wet (amount-wise). That’s what we’ve had for months. Big picture, not individual events. That’s what we have coming up in the shorter term. Unsettled pattern, but not a lot of rain. But don’t key on the word unsettled. Let’s first focus on what will be 2 very nice days today and Saturday as high pressure controls the weather today and hangs on into Saturday as a front approaches from the west. This front will run out of steam and so will probably all the showers it tries to throw our way. As a second front pushes toward the region Sunday, a lot of its shower and thunderstorm activity may also be held at bay to the north and west of the majority of the WHW forecast area. The irony: that ocean-cooled air that so many people can be annoyed with at this time of year will be a big part of the reason the wet weather doesn’t make it into places like Boston and Providence. Now how about that! Eventually, the upper level energy will win out and we should get showers further south and east by later Sunday and Sunday night, so the weekend may end wetter in the areas it was dry most of the time. Early next week, a late spring upper level cool pool will be overhead and while most of the time it will be dry, we’ll have to watch for pop up instability showers both Monday and Tuesday, with the greater chance likely to be Monday.
Forecast details…
TODAY: Mostly sunny. Highs 71-78 except cooler any north or west facing shores. Wind light N then sea breezes.
TONIGHT: Partly cloudy except coastal fog and low clouds. Lows 52-59. Wind light variable.
SATURDAY: Partly sunny. Coastal low clouds and fog may be slow to break in the morning. Highs 67-74, coolest coast. Wind light E to SE.
SATURDAY NIGHT: Mostly cloudy. Slight chance of showers, mainly late-night, favoring areas north and west of Boston. Areas of coastal fog. Lows 53-60. Wind light SE to S.
SUNDAY: Mostly cloudy. Areas of coastal fog and drizzle early to mid morning. Chance of showers mainly very early favoring areas north and west of Boston and again late-day in any location. Highs 62-69. Wind light variable.
SUNDAY NIGHT: Cloudy. Showers likely. Lows 55-62. Wind light variable.
MONDAY: Variably cloudy. Scattered showers possible. Highs 63-70. Wind N 5-15 MPH, higher gusts.
MONDAY NIGHT: Variably cloudy. Scattered showers possible early. Lows 50-57. Wind N 5-15 MPH, higher gusts.
TUESDAY: Partly sunny. Isolated showers possible. Highs 63-70. Wind NW 10-20 MPH, higher gusts possible.

DAYS 6-10 (JUNE 5-9)
Temperatures variable but overall near seasonable. The mean trough position will likely be in eastern Canada with a ridge to the west (Midwest / Great Lakes). This pattern will send disturbances southeastward across New England and bring a few opportunities for showers.

DAYS 11-15 (JUNE 10-14)
I’m staying with the idea of pattern persistence in this period even though some medium range guidance tries to build more of a ridge of high pressure in the East. Still the overall feeling is when this pattern is ready to let go, it will do so quickly, so making no changes for now, but confidence is not high. Still should have a lack of early heat but a few opportunities for showers.

7:32AM

DAYS 1-5 (MAY 30-JUNE 3)
The atmosphere will be a little “blocky” and we end up on the unsettled side, which is a little different than my original idea for this time frame. No, not days of rain, we have some nice days in here as well, but today, not much sun, wet for some areas tonight, and then we have to watch later Saturday onward for other episodes of wet weather as we cycle a series of troughs through the region while high pressure ridging is centered a little further to the west (and another trough west of that, forming a typical set-up we see in spring, and yes, it is still spring).
Forecast details…
TODAY: Mostly cloudy. Highs 68-75, cooler some coastal areas. Wind light S.
TONIGHT: Mostly cloudy. Showers likely and a chance of thunderstorms evening. Lows 55-62. Wind becoming W 5-15 MPH.
FRIDAY: Mostly sunny. Highs 71-78 except cooler any north or west facing shores. Wind NW 10-20 MPH and gusty.
FRIDAY NIGHT: Partly cloudy. Lows 52-59. Wind light N.
SATURDAY: Partly sunny. Highs 67-74, coolest coast. Wind light E to SE.
SATURDAY NIGHT: Mostly cloudy. Chance of showers, mainly late-night. Lows 53-60. Wind light SE to S.
SUNDAY: Mostly cloudy. Chance of showers mainly very early and again late-day. Highs 62-69. Wind light variable.
SUNDAY NIGHT: Cloudy. Showers likely. Lows 55-62. Wind light variable.
MONDAY: Mostly cloudy with showers likely morning. Variably cloudy with possible showers afternoon. Highs 63-70. Wind N 5-15 MPH.

DAYS 6-10 (JUNE 4-8)
Overall pattern keeps us vulnerable to passing disturbances in a trough of low pressure as things don’t change all that much. Temperatures may end up averaging a little below normal. Don’t expect 5 rainy days though. There will be dry weather in here as well. Will work on timing.

DAYS 11-15 (JUNE 9-13)
Going to go with pattern persistence for now. I have a feeling when we break out of this we won’t see it coming that far in advance.

7:27AM

DAYS 1-5 (MAY 29-JUNE 2)
This forecast period carries us through the first weekend of June, which also happens to be the first 2 days of June, and although we don’t see any summer-type heat in it, we don’t see anything like those record low high temperatures of 49 set on the first 2 days of June 2015 at Boston, nor do we see anything quite like the cold/wet pattern of June 2009. It will be unsettled today and Thursday with a couple opportunities for episodes of showers as waves of low pressure travel along a boundary sitting just to the south of the region. For a while it looked like that boundary may end up further north and we’d be warmer. But sometimes it just doesn’t work out that way. This is one of those times. One thing being on the cooler side of the front is doing is protecting us from severe weather that has been occurring not that far away (as close by as NYC area which had hail and a possible tornado in northern NJ, as well as many severe weather reports in Pennsylvania). Once we get to Friday and Saturday, we return to nice weather as high pressure pushes the unsettled weather away, but will it be able to hold it off all the way through Sunday? At the moment I’m thinking no, and that low pressure will push back in from the southwest, returning some wet weather to the region. If it is slower, the rain may hold off, but at day 5 there is time to fine tune this.
Forecast details…
TODAY: Overcast with patchy light fog morning. Mostly cloudy with breaks of sun possible afternoon. Highs 58-65, coolest coast. Wind light variable, mainly onshore near coastal areas.
TONIGHT: Cloudy. Areas of fog. Showers likely. Temperatures steady 58-65 evening, rising slowly overnight. Wind light variable becoming S.
THURSDAY: Mostly cloudy. Risk of showers mainly first half of morning and second half of afternoon. Highs 68-75, cooler some coastal areas. Wind light S.
THURSDAY NIGHT: Mostly cloudy. Showers likely and a chance of thunderstorms evening. Lows 55-62. Wind becoming W 5-15 MPH.
FRIDAY: Mostly sunny. Highs 71-78 except cooler any north or west facing shores. Wind NW 10-20 MPH and gusty.
FRIDAY NIGHT: Partly cloudy. Lows 52-59. Wind light N.
SATURDAY: Partly sunny. Highs 67-74, coolest coast. Wind light E.
SATURDAY NIGHT: Partly cloudy. Lows 52-59. Wind light SE.
SUNDAY: Becoming cloudy. Chance of rain, especially afternoon. Highs 61-68. Wind light SE.

DAYS 6-10 (JUNE 3-7)
Low pressure should pull away allowing drier but cooler air to arrive during June 3 but the low may hang not that far to the northeast keeping it cool and breezy into June 4 as well. Warm-up June 5-6 with mostly fair weather except risk of showers/t-storms later June 6 depending on timing of next frontal system. May remain a little unsettled into June 7 as a trough of low pressure moves through the region. Also turns cooler at the end of the period.

DAYS 11-15 (JUNE 8-12)
It will be hard to shake off the pattern that allows the mean trough to be near the Northeast. This presents the risk of a few showers and thunderstorms at times but also keeps any early heat from getting established.

7:38AM

DAYS 1-5 (MAY 28-JUNE 1)
No significant changes to be made in the forecast that was posted yesterday, so just a quick summary. A boundary sits to our south today and Wednesday and low pressure comes along with wet weather mainly this afternoon and evening as temperatures go down during the day, and again later Wednesday, another day that will be on the cool side of average. A third low comes along with a more northerly track and pulls the boundary at least over the region Thursday when our temperatures vary the greatest south to north. It will also be the day when we add the risk of thunderstorms into the wet weather forecast. By Friday, this mini train of lows is gone, the boundary is back to the south, but far enough so that high pressure builds toward the region for drier weather, but the last low being the strongest and intensifying further in eastern Canada probably means that wind will be involved with the drying process on Friday. Weak high pressure should hold for fair weather Saturday as June arrives but it may not be all the warm as we have a generally onshore flow with the high centered to the north and low pressure off to the south of New England.
Forecast details…
TODAY: Cloudy. Periods of rain develop mid to late morning on. Highs 55-62 occurring before noon, then falling to 48-55 in the afternoon. Wind E 5-15 MPH, higher gusts possible near the coast.
TONIGHT: Cloudy. Periods of rain evening. Areas of drizzle and fog. Lows 45-52. Wind light E.
WEDNESDAY: Mostly cloudy. Risk of showers, mainly late-day. Highs 58-65, coolest coast. Wind light variable.
WEDNESDAY NIGHT: Cloudy. Areas of fog. Showers likely. Humid. Temperatures steady 58-65 evening, rising slowly overnight. Wind light variable.
THURSDAY: Mostly cloudy. Risk of showers/thunderstorms. Humid. Highs 75-82, cooler South Coast. Wind S 5-15 MPH.
THURSDAY NIGHT: Variably cloudy. Risk of showers/thunderstorms early. Humid start, then drying. Lows 55-62. Wind W 5-15 MPH.
FRIDAY: Mostly sunny. Highs 71-78 except cooler any north or west facing shores. Wind NW 10-20 MPH and gusty.
FRIDAY NIGHT: Partly cloudy. Lows 52-59. Wind light N.
SATURDAY: Partly sunny. Highs 67-74, coolest coast. Wind light E.

DAYS 6-10 (JUNE 2-6)
We’re going to have to keep an eye on low pressure to the south and another one to the west to see of high pressure centered to north northeast can hold them off. If we stay fair it will remain on the cooler side of normal, however, on June 2. The remainder of the period should see high pressure shift more to the southeast and a warming trend, but not without the risk of a few showers/thunderstorms from time to time.

DAYS 11-15 (JUNE 7-11)
A trough crossing eastern Canada may send a couple disturbances and shower/t-storm chances into the region a couple times during this period. Temperatures overall should be fairly close to seasonal averages.

8:10AM

DAYS 1-5 (MAY 27-31)
The final 5 days of May. How time flies. But today we pause to remember those who made the ultimate sacrifice for freedom, and what a beautiful weather day to remember them. We should always keep them in our minds as we enjoy ourselves, especially today… Our beautiful weather today is courtesy an area of high pressure that came from Canada. At least the timing was good, because a cold front that crossed the region yesterday with gusty winds and only isolated showers is going to play a little meaner trick on us as it changes uniforms, becomes a warm front, and slowly creeps back to the north toward New England Tuesday while a wave of low pressure moves along it. This will bring rain and much cooler air as we maximize the influence of the still-chilly ocean water. The front may take all day to finally get to the north during Wednesday, another unsettled day though not as cool as Tuesday. We bust into the warm air Thursday, but still with a shower risk, and add the risk of thunderstorms too due to the warmth and humidity. The front, which never gets that far north, goes back to the south again Friday, but this time far enough that we should be able to bring some drying in with clearing and fair weather returning.
Forecast details…
TODAY (MEMORIAL DAY): Mostly sunny. Highs 68-75. Wind NW 5-15 MPH.
TONIGHT: Increasing clouds. Lows 50-57, 45-50 some interior valleys. Wind calm.
TUESDAY: Cloudy. Periods of rain develop mid to late morning on. Highs 55-62 occurring before noon, then falling to 48-55 in the afternoon. Wind E 5-15 MPH, higher gusts possible near the coast.
TUESDAY NIGHT: Cloudy. Periods of rain evening. Areas of drizzle and fog. Lows 45-52. Wind light E.
WEDNESDAY: Mostly cloudy. Risk of showers. Highs 58-65, coolest coast. Wind light SE to S.
WEDNESDAY NIGHT: Mostly cloudy. Areas of fog. Showers likely. Humid. Temperatures steady 58-65 evening, rising slowly overnight. Wind S to SW 5-15 MPH.
THURSDAY: Variably cloudy. Risk of showers/thunderstorms. Humid. Highs 75-82, cooler South Coast. Wind SW 10-20 MPH.
THURSDAY NIGHT: Variably cloudy. Risk of showers/thunderstorms early. Humid start, then drying. Lows 55-62. Wind W 5-15 MPH.
FRIDAY: Mostly sunny. Highs 71-78. Wind NW 5-15 MPH.

DAYS 6-10 (JUNE 1-5)
Weak overall weather systems but the tendency will be to have high pressure shift a little more offshore and for the region to be in a predominant southwesterly flow with mostly fair weather, limited shower/t-storm risks, and warmer than average temperatures, but have to watch for ocean breezes and a system from the west which may enhance the shower risk later June 2 and another one sometime June 5.

DAYS 11-15 (JUNE 6-10)
A trough crossing eastern Canada may send a couple disturbances and shower/t-storm chances into the region a couple times during this period. Temperatures overall should be fairly close to seasonal averages.

7:38AM

DAYS 1-5 (MAY 26-30)
As promised, the wet weather came at night between days 1 & 2 of the Memorial Day Weekend. The last few lingering showers are moving off the East Coast of Massachusetts early this morning and that ends the warm front precipitation episode. Some of the showers were indeed thunderstorms in the late-night hours, providing a bit of a light show, especially west and south of Boston. Now today, its warmth and increased humidity as the features, but we cannot rule out a pop up shower or thunderstorm this afternoon and very early evening in the slightly unstable air in place. The support for showers and storms is not really that great, however, so they should be just isolated, and short-lived. A cold front will cross the region this evening without any fanfare, just a wind shift and a drop in humidity during the night. This will set up a spectacular Memorial Day as high pressure moves in and brings sunshine with dry and mild air, although the coast will likely cool due to a sea breeze. But there will be no weather issues for outdoor observances / ceremonies / parades for the day. Unsettled weather will return during the Tuesday-Thursday period when we have a warm front approach Tuesday and then we may see that boundary hang up right in our area Wednesday and Thursday, making for a nearly impossible temperature forecast which I will lean toward the warmer side of for now, but with the caveat these may be adjusted downward. It will be hard to time any wet weather until we get closer to those days.

DAYS 6-10 (MAY 31-JUNE 4)
High pressure should become more dominant but it will be on the weaker side and a boundary between slightly cooler/drier air and much warmer/humid air will sit to the south for a good portion of this period. The overall idea in this pattern is mostly dry, temperatures close to seasonal averages overall. But any time a boundary sits to the south it must be watched for the potential of sending unsettled weather back into the region, so we will be somewhat vulnerable and will have to keep an eye on it.

DAYS 11-15 (JUNE 5-9)
A trough crossing eastern Canada may send a couple disturbances and shower/t-storm chances into SNE a couple times during this period. Temperatures overall should be fairly close to seasonal averages.

2:50AM

DAYS 1-5 (MAY 25-29)
Memorial Day Weekend will feature generally nice weather, with the one unsettled weather interruption tucked into an 8-hour period Saturday night to early Sunday morning, when high pressure that brings nice weather during Saturday’s daytime gives way to a warm front crossing the region. Once this front clears the area early Sunday the humidity will go up and it will be the warmest day of the 3, and we will have to watch for a pop up shower or thunderstorm in isolated locations later in the day. A cold front will fairly quietly cross the region Sunday night and then high pressure will move in for Memorial Day with spectacular weather and no issues for outdoor observances. After that, we get into an unsettled period of weather as a frontal boundary will be in the vicinity Tuesday and Wednesday. It looks like we’ll be on the cooler side of the boundary Tuesday and the warmer side Wednesday, with a few episodes of showers and possible thunderstorms during those days, which will will have to fine-tune the timing of as it gets closer.

DAYS 6-10 (MAY 30-JUNE 3)
A front should still be on the vicinity, leaning toward SNE on the warmer side with a risk of showers/thunderstorms during May 30, then the front pushing through with drier weather for May 31. June 1-2 weekend starts dry and turns humid and may end with a risk of showers/thunderstorms before fair weather returns to end the period. Temperatures near to above normal overall for the period.

DAYS 11-15 (JUNE 4-8)
A trough crossing eastern Canada may send a couple disturbances and shower/t-storm chances into SNE around June 5 and 7 (timing uncertain). temperatures overall should be fairly close to seasonal averages.

7:16AM

DAYS 1-5 (MAY 24-28)
Low pressure east of New England combined with high pressure approaching from the west, and cold air aloft, will turn today into a day with lots of clouds and a cool breeze, before clearing arrives tonight and Saturday is quite a nice day as high pressure moves across the region. A trough of low pressure will cross the region Saturday night and first thing Sunday, the most unsettled part of the Memorial Day Weekend, with the only other shower threat being of the isolated variety as a secondary trough crosses the area during Sunday afternoon. Sunday will be the warmest and most humid of the 3-day span. High pressure will ensure a splendid Memorial Day, which will be mild, though slightly cooler and less humid than Sunday. Another small area of low pressure will approach by Tuesday with a threat of additional showers at that time.

DAYS 6-10 (MAY 29-JUNE 2)
West to east flow, timing of systems should bring greatest chance of rain showers in the late May 29 to early May 30 time frame and in the late May 31 to early June 1 time frame. By no means does this look like a wet pattern, however. Temperatures should average slightly above normal for the 5-day period.

DAYS 11-15 (JUNE 3-7)
Disturbances with shower and possible t-storm risks June 3, 5, and 7 otherwise mainly dry weather with temperatures near to above normal.

7:23AM

DAYS 1-5 (MAY 23-27)
This 5-day portion of the blog forecast takes us right through the Memorial Day Weekend, and considering the pattern we had been in for the vast majority of the spring, this is not really that bad an outlook. The cloudiest of the 5 will be today as a warm front approaches, and this front may produce a few showers and possibly a thunderstorm later in the day, favoring areas north and west of Boston. Its parented by low pressure diving southeastward from eastern Canada, destined to cross Maine tonight while dragging its cold front through southern New England, and this front will likely set off some showers and thunderstorms, a few of which may be strong. While we are not in the SPC severe weather area, I cannot completely rule out a severe storm or two, so it will be a situation we will have to watch for tonight. The low pressure that crosses Maine will become a temporary pest in the ocean to the east, sending some extra clouds, a northeast breeze, and perhaps a few showers across the region Friday, although the day will be mainly dry. Then we get to the Memorial Day Weekend when we’ll be quickly into a southwesterly to westerly flow as a couple troughs cross the region, one later Saturday, and one sometime on Sunday. This period will be warmer than average but will not be without a couple rain shower or thunderstorm threats, but the time of rainfall in any given location will be a small percentage of the overall time during those 2 days, favoring Saturday night and early Sunday, and perhaps in a few spots later Sunday. High pressure looks set to move in for a splendid Memorial Day, with the previous late-day shower threat no longer an issue as that system will be slower to approach.

DAYS 6-10 (MAY 28-JUNE 1)
Timing is not certain for this period but this is a rough idea of what a west-to-east flow should bring the region, and that is a warm frontal passage with showers May 28, a shot of very warm to hot and humid air with a risk of late-day thunderstorms May 29, drying and somewhat cooler but nice weather May 30, then a risk of a shower or thunderstorm between later May 31 and early June 1 with the next passing disturbance.

DAYS 11-15 (JUNE 2-6)
Favored fair weather to start and end period with unsettled risk most likely mid period. Temperatures near to above normal.
