DAYS 1-5 (JUNE 9-13)
An ocean storm side-swipes southern New England early today with a wet start over parts of Cape Cod. A disturbance from the west may trigger a few afternoon showers and thunderstorms but when today is over a large portion of the region will have seen no rain at all. This weekend a westerly flow develops and we transition to the feel of summer, but another disturbance may trigger a few showers/storms again on Saturday but it appears these will be only isolated. Then comes a potential heatwave for Sunday through Tuesday, but not for everybody. There will be cooler temperatures in the normal cooler spots such as Cape Cod and the Islands, and by Tuesday we’ll have to see about the timing of a front trying to push down from the north which may cool portions of the region. An interesting note: If Boston should record a heatwave during the Sunday-Tuesday period, it will be the first time that they have seen two heatwaves before June 15.
TODAY: Partly sunny to mostly cloudy. Early rain areas of Cape Cod. Isolated to scattered showers and a slight chance of thunderstorms developing to the west and pushing to the east. Any showers/storms end by evening with decreasing clouds. Highs 62-67 Cape Cod and Islands, 68-75 elsewhere. Wind N 5-15 MPH shifting to W.
TONIGHT: Mostly clear. Lows 53-58. Wind W 5-15 MPH.
SATURDAY: Partly sunny. Isolated showers/thunderstorms mainly mid to late afternoon. Highs 68-75 South Coast, 76-82 elsewhere. Wind W 5-15 MPH.
SATURDAY NIGHT: Partly cloudy. Lows 58-64. Wind WSW 5-15 MPH.
SUNDAY: Mostly sunny. Highs 77-84 South Coast, 85-93 elsewhere. Wind WSW 10-20 MPH and gusty.
MONDAY: Mostly sunny. Lows 63-72. Highs 77-85 South Coast, 86-94 elsewhere.
TUESDAY: Partly sunny. Chance of thunderstorms. Lows 65-73. Highs 77-85 South Coast, 86-94 elsewhere but may turn cooler especially NH and eastern MA later.

DAYS 6-10 (JUNE 14-18)
Fair and mild June 14 as high pressure moves down from eastern Canada. A warmer and hotter and more humid pattern may evolve during the June 15-18 period but along with the threat of a few showers and thunderstorms from time to time as high pressure builds off the Atlantic Coast.

DAYS 11-15 (JUNE 19-23)
Early indications are for a more zonal (west to east) flow with seasonable but slightly variable temperatures and episodes of passing showers.

7:45AM

6:25PM edit for the addition of a discussion for days 1-5.

DAYS 1-5 (JUNE 8-12)
Low pressure moves off the Mid Atlantic Coast tonight and passes southeast of New England Friday. Some rain gets into RI and southeastern MA and perhaps into the I-95 corridor but areas to the west will not likely see much if any rain from the low pressure system. However, a disturbance approaching from the west will trigger some showers and possible thunderstorms to the west and north of Boston during the afternoon and these will track east southeastward while fading away late in the day. There is only the slight risk of a pop up shower or storm Saturday as a little chilly air lingers above while the surface warms. Then we’re into the heat for Sunday-Monday. At this time it looks like any boundary of cooler air, which often lurks to the north this time of year when it heats up, will stay there.
TODAY: Sunshine, then increasing clouds from the southwest late. Highs 62-67 coast, 68-73 interior. Wind light SE.
TONIGHT: Thickening overcast. Chance of rain RI and southeastern MA overnight. Lows 52-57. Wind SE 5-15 MPH.
FRIDAY: Overcast morning with periods of rain/drizzle RI and eastern MA, possibly NH Seacoast. Mostly cloudy to partly sunny afternoon with a possible late-day or early evening shower or thunderstorm favoring southwestern NH, central MA, and northeastern CT. Highs 60-65 coast, 66-71 interior. Wind E 5-15 MPH morning, S 5-15 MPH afternoon.
SATURDAY: Partly cloudy. Isolated showers or thunderstorms. Lows in the 50s. Highs from the middle 70s to lower 80s.
SUNDAY: Mostly sunny. Lows from the middle 50s to lower 60s. Highs in the upper 70s South Coast, 80s to lower 90s elsewhere.
MONDAY: Partly cloudy. Lows in the 60s. Highs from the upper 80s to middle 90s, cooler some coastal areas.

DAYS 6-10 (JUNE 13-17)
Staying with the heat for June 13 for now but will watch a boundary to the north. This should make it through by June 14 which will be dry but cooler. A few showers at times but largely rain-free and fairly warm June 15-17.

DAYS 11-15 (JUNE 18-22)
Shower threat early and again late period. Temperatures near to above normal.

6:40AM

DAYS 1-5 (JUNE 7-11)
Drying north to south today as high pressure in eastern Canada pushes the wet weather out of southern New England, but there will be an attempted comeback as a new low pressure area moves off the Mid Atlantic Coast and passes southeast of New England Thursday night and Friday. The highest chance of wet weather is in RI and eastern MA from this system. A cold front from the west helps to push everything out of here Friday night and sets up a weekend that looks dry and displays a complete reversal of what we have been experiencing.
TODAY: Overcast start with areas of drizzle and one final area of rain in southern NH and northeastern MA drying up as it pushes south. Clearing north to south later morning through afternoon with increasing sun. Highs 57-62 coast, 63-68 interior. Wind N to NE 5-15 MPH.
TONIGHT: Clear. Lows 45-50 interior valleys, 51-56 elsewhere. Wind light variable.
THURSDAY: Sunshine, then increasing clouds from the southwest late. Highs 62-67 coast, 68-73 interior. Wind light SE.
THURSDAY NIGHT: Thickening overcast. Chance of rain RI and southeastern MA overnight. Lows 52-57. Wind SE 5-15 MPH.
FRIDAY: Overcast morning with periods of rain/drizzle RI and eastern MA, possibly NH Seacoast. Mostly cloudy to partly sunny afternoon with a possible late-day or evening shower or thunderstorm favoring southwestern NH, central MA, and northeastern CT. Highs 60-65 coast, 66-71 interior. Wind E 5-15 MPH morning, S 5-15 MPH afternoon.
SATURDAY: Partly cloudy. Lows in the 50s. Highs from the middle 70s to lower 80s.
SUNDAY: Mostly sunny. Lows from the middle 50s to lower 60s. Highs from the upper 70s South Coast to 80s elsewhere.

DAYS 6-10 (JUNE 12-16)
Mainly dry and warm to hot weather overall June 12-14 but watch for a back-door cold front to possibly cool at least southeastern NH and eastern MA for part of this time. Possible showers June 15 then fair June 16 with a cooling trend.

DAYS 11-15 (JUNE 17-21)
Cool start, warmer finish, with a period of showers possible during the transition.

7:36AM

DAYS 1-5 (JUNE 6-10)
We remain in the “dank tank” today as low pressure to the south and high pressure to the north combine for a damp and very cool June day, one in which record low maximum temperatures may be challenged. Slow improvement follows on Wednesday as high pressure to the north dries the region out. But another low pressure area to the south will push the clouds back in during Thursday and likely lead to some wet weather Thursday night into Friday before improvement occurs yet again by the start of the coming weekend.
TODAY: Overcast. Drizzle, areas of fog, and periods of rain. Highs 48-55. Wind E to NE 10-20 MPH, higher gusts.
TONIGHT: Overcast. Drizzle, areas of fog, and periods of rain, but all diminishing overnight. Lows 45-50. Wind NE to N 5-15 MPH, higher gusts.
WEDNESDAY: Very slow clearing north to south but completely clearing may never reach the South Coast. Highs 55-60 coast, 61-68 interior. Wind N 5-15 MPH.
THURSDAY: Increasing clouds. Chance of rain at night. Lows 48-55. Highs 63-70, coolest coast.
FRIDAY: Cloudy with a chance of rain favoring southern and eastern areas mainly morning. Slow clearing later Lows 50-58. Highs 63-70.
SATURDAY: Partly cloudy. Isolated showers. Lows 52-59. Highs 70-77, cooler coast.

DAYS 6-10 (JUNE 11-15)
Warm to hot weather June 11-14. Showers/thunderstorms possible June 14 and/or 15 with a cool down by June 15.

DAYS 11-15 (JUNE 16-20)
Cool early period followed by a warming trend which may be lead in by a period of wet weather.

7:35PM

DAYS 1-5 (JUNE 5-9)
The latest bout of cool/damp spring weather is underway and as previously mentioned will be slow to end, though improvement should arrive by midweek at least slowly. It remains to be seen when we fully break out and change the pattern. There are signs via medium range guidance it happens as early as next weekend or just beyond, but model inconsistencies and past experience shows not to jump on this idea too quickly. With this in mind, there are no major changes to the forecast at this time.
TODAY: Overcast. Periods of rain and drizzle. Highs 55-60. Wind E to NE 10-20 MPH.
TONIGHT: Overcast. Periods of rain and drizzle. Lows 46-51. Wind NE 10-20 MPH, higher gusts.
TUESDAY: Overcast with rain/drizzle likely. Highs 48-55. Wind NE 10-20 MPH, higher gusts.
WEDNESDAY: Mostly cloudy with a chance of showers/drizzle. Lows from the lower to middle 50s. Highs from the upper 50s to lower 60s coast to the middle and upper 60s interior.
THURSDAY: Partly sunny with a slight chance of showers. Lows in the 50s. Highs from the lower 60s coast to lower 70s interior.
FRIDAY: Partly sunny with a slight chance of showers. Lows in the 50s. Highs from the middle 60s coast to middle 70s interior.

DAYS 6-10 (JUNE 10-14)
Optimistically forecasting improving and warmer weather during this period but this is with low confidence at this time.

DAYS 11-15 (JUNE 15-19)
Turning somewhat cooler early in the period and warmer again later in the period with some possible showery weather at times.

12:17PM

DAYS 1-5 (JUNE 4-8)
I was hoping to have a little better idea by today of when the upcoming cool/wet stretch (starting tonight and lasting through at least Tuesday) will break, but I don’t have a great feel for it yet, unfortunately. Based on that, I’m not making any significant changes to this forecast other than updating the time periods and tweaking a few small things. Starting at the end of this period (Thursday), confidence drops significantly so there will be plenty of updating and fine-tuning to come, if necessary.
TODAY: Sunshine followed by increasing clouds. Rain arriving west to east late in the day. Highs 61-66 coast, 67-72 interior. Wind light SE.
TONIGHT: Overcast. Periods of rain and drizzle. Chance of thunderstorms. Lows 50-55. Wind SE to E 5-15 MPH.
MONDAY: Overcast. Periods of rain and drizzle. Highs 55-60. Wind E to NE 10-20 MPH.
TUESDAY: Overcast with rain/drizzle likely. Lows 50-55. Highs 55-60.
WEDNESDAY: Mostly cloudy with a chance of showers/drizzle. Lows from the lower to middle 50s. Highs from the upper 50s to lower 60s coast to the middle and upper 60s interior.
THURSDAY: Partly sunny with a slight chance of showers. Lows in the 50s. Highs from the lower 60s coast to lower 70s interior.

DAYS 6-10 (JUNE 9-13)
Optimistically forecasting improving and warmer weather during this period but this is with low confidence at this time. Not expecting a big pattern change in this time frame even if we do see some warmer and dry weather.

DAYS 11-15 (JUNE 14-18)
Should trend cooler including some additional showery weather during this period, which does not mean wet all of the days. This is a low confidence forecast at this time.

3:00AM

DAYS 1-5 (JUNE 3-7)
A northwesterly air flow will bring cool weather to southern New England today, and with upper level low pressure still extending back over the region as it drifts away to the northeast, a few showers may pop up, but the bulk of the region will remain dry throughout the day. A narrow sliver of high pressure moves over the region tonight and early Sunday but the approach of low pressure from the west will send more clouds into the region during Sunday with rain reaching western areas by the end of the day and eastern areas by evening or nighttime. This will be the start of another stretch of wet/cool weather which will last through Tuesday at least. It remains to be seen how quickly this will depart and whether or not Wednesday will be overcast and wet or show partial improvement.
TODAY: Sunshine to start then partly sunny to mostly cloudy with isolated to scattered showers and a slight chance of thunderstorms. Highs 64-69. Wind NW 10-20 MPH with higher gusts.
TONIGHT: Partly cloudy evening. Clear overnight. Lows 42-47 interior valleys, 48-53 coast and urban areas. Wind light NW becoming variable.
SUNDAY: Sunshine followed by increasing clouds. Rain arriving west to east late in the day. Highs 61-66 coast, 67-72 interior. Wind light SE.
SUNDAY NIGHT: Overcast. Periods of rain and drizzle. Chance of thunderstorms. Lows 50-55. Wind SE to E 5-15 MPH.
MONDAY: Overcast. Periods of rain and drizzle. Highs 55-60. Wind E to NE 10-20 MPH.
TUESDAY: Overcast with rain/drizzle likely. Lows 50-55. Highs 55-60.
WEDNESDAY: Mostly cloudy with a chance of showers. Lows 50-55. Highs 58-65.

DAYS 6-10 (JUNE 8-12)
Some uncertainty if improvement takes place early in the period or toward the end of the period. So a low confidence forecast at this time is for starting cooler than normal with a few showers around, then a trend to warmer with mainly dry weather.

DAYS 11-15 (JUNE 13-17)
Cooler with some shower activity possible early to mid period then warmer/drier again.

12:03PM

Apologies for late update and lack of discussion…

DAYS 1-5 (JUNE 2-6)
TODAY: Partly sunny. Scattered midday and afternoon showers/thunderstorms. Highs 64-73, coolest South Coast. Wind SW 10-20 MPH.
TONIGHT: Partly cloudy. Lows 53-60. Wind W 5-15 MPH.
SATURDAY: Partly sunny. Highs 63-70. Wind NW 10-20 MPH.
SUNDAY: Increasing clouds. Chance of rain at night. Lows 53-60. Highs 60-67.
MONDAY AND TUESDAY: Cloudy. Chance of rain/drizzle. Lows 48-55. Highs 56-63.

DAYS 6-10 (JUNE 7-11)
A very cool and unsettled period of weather with the cloudiest and wettest likely to be at the beginning but very slow to break out after.

DAYS 11-15 (JUNE 12-16)
Drier weather expected but temperatures still likely running on the cooler side of normal.

7:27AM

THUNDERSTORM REVIEW
Many of you saw some incredible pictures and videos of thunderstorms that rolled across much of the region late Wednesday afternoon and early Wednesday evening. For the most part, these storms were not severe in eastern areas, but there were a few reports of damage in southern NH and more areas of damage where storms contained more substantial hail and powerful winds in western and west central MA. An isolated downpour/thunderstorm popped up near Concord and Acton MA around 6PM Wednesday well ahead of the main line of storms, which was just entering central MA at that time. This isolated storm, while never becoming severe, organized itself into a super cell storm, which then split into 2 storms. This is something that is seen fairly frequently especially in the Plains and Midwest, and occasionally around here. Often when this happens, there will be a counterclockwise rotation of the storm on the right side and a clockwise rotation of the storm on the left, which is often the weaker of the two. In this case, it was the clockwise-rotating storm on the left that maintained its intensity while the other member faded away. Eventually, the surviving half of the storm did dissipate as well, but not before providing a spectacular view, especially to its north, where a sharp rotating storm tower was visible, dark grey in the shadow of clouds from the main line of storms to the west. That made the storm look more menacing for a time before it weakened and dissipated, but not before dropping some heavy rain and hail and causing some gusty winds along its path between Concord and Lowell and into the region just beyond Lowell in the Merrimack Valley. The main line came along behind this, impacting different areas to varying degrees depending on its strength as it passed by. I happened to drive up I-93N to Methuen MA where I intercepted one of the stronger parts of the line at the time it reached the area (around 8:30PM) and encountered some gusty wind, downpours, small hail (about pea sized) and a number of cloud-to-ground lightning strikes. I then followed the weakening storm back down I-93S as it moved away to the east giving me a little bit of a lightning show.

DAYS 1-5 (JUNE 1-5)
So, what’s ahead now that June is here? Basically more of the same weather pattern we’ve been in, but there will be some nice weather too. The first 4 days of this new month will not be all that bad, with only passing shower/t-storm threats from a couple fronts moving through the region today and Friday. When we get to Sunday we’ll be watching approaching low pressure from the west. There are many graduations and other activities planned outdoors for Sunday and the timing of the onset of any rain will be critical. At this time I continue to feel that it will hold off until the very end of the day or night for most of the region, but will continue to monitor this. That will be the beginning of what may be a lengthy period of cool/damp weather that will bring additional wet weather for the end of this 5-day period.
TODAY: Partly cloudy. Isolated afternoon showers/thunderstorms. Highs 66-73 South Coast, 74-80 elsewhere. Wind W 5-15 MPH.
TONIGHT: Mostly clear. Lows 53-60. Wind W 5-15 MPH.
FRIDAY: Partly sunny. Scattered midday and afternoon showers/thunderstorms. Highs 64-73, coolest South Coast. Wind SW 10-20 MPH.
FRIDAY NIGHT: Partly cloudy. Lows 53-60. Wind W 5-15 MPH.
SATURDAY: Partly sunny. Highs 63-70. Wind NW 10-20 MPH.
SUNDAY: Increasing clouds. Chance of rain at night. Lows 53-60. Highs 60-67.
MONDAY: Cloudy. Chance of rain/drizzle. Lows 48-55. Highs 56-63.

DAYS 6-10 (JUNE 6-10)
A very cool and unsettled period of weather with the cloudiest and wettest likely to be at the beginning but very slow to break out after.

DAYS 11-15 (JUNE 11-15)
Drier weather expected but temperatures still likely running on the cooler side of normal.

I’m going to make this version of the summer outlook fairly quick, simple, and to the point. Our drought now essentially behind us, and the pattern having been wet, it’s obvious we are not going into summer 2017 the way we did just a year ago. The pattern in the spring was wet, with a cold March, a milder April, and a very cool May (the coolest since 2005 and the first below normal May in many parts of the region since 2008). What follows is a short summary of what I expect for the summer. I have observed forecasts from colleagues, NOAA, and other professionals and I will say that I’m in general agreement with most of them.

SUMMER 2017 OVERVIEW
A pattern of blocking at high latitudes has resulted in a pattern of frequently cool, often cloudy, and occasionally wet weather for New England during the last several weeks, and this general idea will continue into the early and mid part of June, though as climatology dictates, we continue to warm slowly as we advance the calendar so the direct impact, while less, will still be noticeable when compared to daily normal values, especially for temperature. As we move into late June, we should see a shift of the pattern as blocking weakens and dissipates, and a more zonal flow takes over. This will allow more episodes of westerly flow and more seasonable warmth with occasional spikes of heat alternating with brief cool-downs as air masses change with passing systems on a more progressive jet stream. Heading into the heart of summer, provided a forecast El Nino is slow to develop, and I suspect it will be, we should see an occasional Bermuda High setup as high pressure in the western Atlantic occasionally retrogrades (backs westward) toward the East Coast. During these times we will see our higher humidity, some heat, and episodic showers/thunderstorms. The shower activity this summer will be more prolific than that of last summer, keeping overall precipitation amounts near to above normal and preventing a slip back into drought. This, along with what ends up being a warmer middle and end, will skew temperatures to near to above normal. So the theme of summer 2017, after its cool start, will be warm and wet.

JUNE SPECIFICS
Current pattern of blocking and frequent troughing in the Northeast continues through mid month with precipitation above normal and temperatures below normal. Pattern breaks down around the summer solstice and the last third of the month will be warmer and drier with passing systems in a more progressive jet stream flow causing brief shower/thunderstorm threats.
Temperature: Below normal.
Precipitation: Above normal.

JULY SPECIFICS
The first half of the month should feature the pattern that is established during the latter third of June. The second half of the month will feature an alternating between the early July pattern and a more humid and showery Bermuda High pattern. Though this type of pattern does not typically produce all day rains, we’d have to be on the lookout for some tropical moisture feeds that could provide days with frequent showers/thunderstorms.
Temperature: Near to above normal.
Precipitation: Near to above normal.

AUGUST SPECIFICS
Take the pattern of the second half of July and continue it for August, but with more emphasis on Bermuda High and less so on westerly flow and progressive jet stream. Should be a warm and humid month with episodic showers and thunderstorms. Though we cannot predict very far in advance whether or not a tropical storm or hurricane will threaten the region, or any part of the US coast, we can say that a Bermuda High pattern can leave the East Coast vulnerable, should a storm form and be in the right position to get around the western side of such a high pressure area.
Temperature: Above normal.
Precipitation: Near to above normal.

8:20AM

DAYS 1-5 (MAY 31-JUNE 4)
This is the final day of what has been a cool and wet May overall, despite a 3-day heatwave for many locations during mid month. This will be the first May since 2008 where the temperature comes in below normal in Boston, and the coolest May there since 2005. Our final day of the month will feature more cloudiness but eventually some areas of sunshine. A weakening cold front in the region may trigger a few showers through early afternoon and then another approaching cold front will send showers/thunderstorms toward the region from the west this evening but they will have trouble surviving all the way through the region as we lose daytime heating and have somewhat more stable air in place compared to the air to the west of the region. Though it will be more unstable than it was yesterday so some of the activity may survive to some extent. Will watch this as the day goes on. A drier westerly flow will take over for Thursday but another weak disturbance may trigger a shower or 2 west of Boston in the afternoon. The next in a parade of fronts will approach later Friday with yet another risk of showers/thunderstorms. Current indications are that this will move along enough so that improvement will be seen Saturday. High pressure then moves across the region keeping most of the weekend dry though by late Sunday we’ll be watching the approach of a low pressure area from the southwest. At the moment I think this will hold off until at least Sunday night.
TODAY: Mostly cloudy through midday with isolated to scattered showers. Partly sunny afternoon with isolated showers. Mostly cloudy late.
Highs 63-68 coast, 68-73 interior. Wind SE to S 5-15 MPH.
TONIGHT: Mostly cloudy. Scattered showers and thunderstorms especially west and north of Boston in the evening. Lows 58-63. Wind SW 5-15 MPH with higher gusts early, shifting to W.
THURSDAY: Mostly sunny to partly cloudy. Isolated showers mainly west of Boston favoring central MA and southwestern NH in the afternoon. Highs 65-70 Cape Cod, 71-76 elsewhere. Wind W 5-15 MPH.
THURSDAY NIGHT: Mostly clear. Lows 54-62. Wind W 5-15 MPH.
FRIDAY: Variably cloudy. Chance of showers/thunderstorms mainly late day and evening. Highs 64-69 South Coast, 70-76 elsewhere. Wind SW 10-20 MPH.
SATURDAY: Decreasing clouds. Chance of showers early, favoring far eastern and southern areas. Lows from the upper 50s to middle 60s. Highs in the 70s except 60s South Coast.
SUNDAY: Increasing clouds. Chance of rain at night. Lows in the 50s. Highs from the middle 60s to lower 70s, coolest coastal areas.

DAYS 6-10 (JUNE 5-9)
A string of low pressure areas will pass south of the region with at least cool/cloudy if not wet weather June 5-6 with little or very slow improvement but continued cool weather June 7-9 as upper level low pressure hangs around.

DAYS 11-15 (JUNE 10-14)
Though not as cool as the previous 5-day period, temperatures likely remain below normal as the pattern favors a trough centered just to the east of the region and a cooler supply of air from eastern Canada. It should be drier during this period.

8:35AM

DAYS 1-5 (MAY 30-JUNE 3)
A 2-stage weather transition takes place during the next 3 days brought about by the passage of 2 cold fronts. The first one coming through tonight will have initiated showers/thunderstorms north and west of southern New England but they will run into air that is stable and has been fairly cool and lacking sun’s heating. The second one will arrive Wednesday evening and will send another batch of showers/thunderstorms toward the region, which may survive further east due to some solar heating and a more unstable atmosphere that results. Behind this front comes a wonderful day to start June on Thursday, but by the time the second day of the new month arrives, another low pressure system will approach and bring some humidity along with the chance of showers and thunderstorms. This system may be slow to get through the region so improvement may be slow to come on Saturday – something to watch as the week goes on.
TODAY: Mostly cloudy. Highs 58-63 coast, 64-69 interior. Wind light SE to S.
TONIGHT: Mostly cloudy. Scattered showers mainly west and north of Boston in the evening. Lows 53-58. Wind S 5-15 MPH.
WEDNESDAY: Variably cloudy. Highs 63-68 South Coast, 68-73 elsewhere. Wind S 5-15 MPH.
WEDNESDAY NIGHT: Mostly cloudy. Scattered showers and thunderstorms especially west and north of Boston in the evening. Lows 58-63. Wind SW 5-15 MPH with higher gusts early, shifting to W.
THURSDAY: Mostly sunny. Highs 65-70 Cape Cod, 71-76 elsewhere. Wind W 5-15 MPH.
FRIDAY: Variably cloudy. Chance of showers/thunderstorms. Lows from the middle 50s to lower 60s. Highs in the 70s except 60s South Coast.
SATURDAY: Variably cloudy. Chance of showers, favoring the morning. Lows from the upper 50s to middle 60s. Highs in the 70s except 60s South Coast.

DAYS 6-10 (JUNE 4-8)
An unsettled weather pattern is expected during this period. That does not mean rain every day all day. Will be watching for an approaching low early in the period that may keep much of its moisture to the south of the region, and another system mid to late period. Temperatures near to below normal on average.

DAYS 11-15 (JUNE 9-13)
Pattern will likely feature temperatures near to below normal and at least a couple threats of wet weather heading toward mid June.

12:13PM

DAYS 1-5 (MAY 29-JUNE 2)
A weakening low to the northwest and a developing offshore low to the southeast combine to bring unsettled weather for this Memorial Day, along with very cool air, especially in eastern areas due to an easterly wind. A somewhat milder southerly flow takes over for Tuesday and Wednesday, the last 2 days of May, but don’t expected brilliant sunshine as a couple of disturbances have to pass through the region bringing a couple opportunities for showers and a few thunderstorms. A break comes for the first day of June Thursday as a drier westerly air flow takes over before the next frontal system arrives Friday with a shower and thunderstorm threat once again.
THIS AFTERNOON: Overcast. Areas of drizzle. Periods of rain. Temperatures steady 48-53 coast, 54-59 interior. Wind E 5-15 MPH interior and 10-20 MPH coast with higher gusts.
TONIGHT: Cloudy. Areas of rain/drizzle gradually diminishing. Patchy fog. Lows 44-49. Wind NE 5-15 MPH.
TUESDAY: Mostly cloudy to partly sunny. Chance of drizzle early. Isolated showers. Highs 58-63 coast, 64-69 interior. Wind light SE.
TUESDAY NIGHT: Mostly cloudy. Scattered showers and a chance of thunderstorms. Lows 53-58. Wind S 5-15 MPH.
WEDNESDAY: Variably cloudy. Scattered showers and a chance of thunderstorms. Highs 63-68 South Coast, 68-73 elsewhere. Wind S 5-15 MPH.
THURSDAY: Mostly sunny. Lows in the 50s. Highs in the 70s except 60s Cape Cod.
FRIDAY: Variably cloudy. Chance of showers/thunderstorms. Lows from the middle 50s to lower 60s. Highs in the 70s except 60s South Coast.

DAYS 6-10 (JUNE 3-7)
Expect dry weather for the June 3-4 weekend but probably sun/cloud mix and temperatures near to slightly below normal. Cooler/unsettled weather looks more likely for the June 5-7 period.

DAYS 11-15 (JUNE 8-12)
Pattern will likely feature temperatures near to below normal and at least a couple threats of wet weather heading toward mid June.

3:16AM

DAYS 1-5 (MAY 28-JUNE 1)
The middle day of the Memorial Day Weekend will feature fair weather courtesy of high pressure, but a reminder that tides are astronomically high and some coastal flooding may occur around high tide times. A low pressure system will approach from the west Memorial Day Monday, which its center destined to pass to the north of the region, however an occluding front trailing from it will help spawn another low offshore to the south and southeast of New England by evening. This setup and evolution leads to a mainly cloudy day with period of wet weather from midday through evening. Hopefully, it will stay dry for most of the morning when the majority of outdoor parades and ceremonies are. When we get to Tuesday and Wednesday, a warmer westerly flow will take over, but a couple passing disturbances may ignite some showers and possible thunderstorms. Dry weather is expected for Thursday.
TODAY: Partly cloudy. Highs 60-65 coast, 66-71 interior. Wind light variable with coastal sea breezes.
