Thursday Forecast

7:31AM

DAYS 1-5 (JUNE 15-19)
High pressure moves offshore today, which will still be a very nice day, and then a warm front approaches Friday, turning the weather unsettled. This front will crawl across the region early Saturday so improvement may be a little slow in coming, but it will arrive, and then set up a very warm and humid Father’s Day on Sunday. A cold front will approach early next week and may also be slow to move through, so humidity will continue high and the shower/thunderstorm chance will be present.
TODAY: Mostly sunny. Highs 72-78, coolest coast. Wind light variable with sea breezes.
TONIGHT: Increasing clouds. Lows 53-59. Wind light SE.
FRIDAY: Mostly cloudy. Showers becoming more likely during the day. Highs 68-75, coolest coast. Wind SE 5-15 MPH.
FRIDAY NIGHT: Cloudy. Showers likely. Areas of fog. Lows 60-67. Wind SE up to 10 MPH.
SATURDAY: Mostly cloudy morning with areas of fog and a possible shower. Mostly cloudy to partly sunny afternoon. More humid. Highs 70-78, coolest coast. Wind SE to SW 5-15 MPH.
SUNDAY: Partly cloudy. Humid. Lows in the 60s. Highs in the 80s, some 70s South Coast.
MONDAY: Partly sunny. Chance of showers/thunderstorms. Humid. Lows in the 60s. Highs in the 80s, cooler South Coast.

DAYS 6-10 (JUNE 20-24)
Higher humidity and a shower threat persists June 20 then returns at the end of the period, while the middle days are drier and seasonably warm.

DAYS 11-15 (JUNE 25-29)
A more zonal pattern is still expected with a few episodes of showers/storms from passing disturbances and more variable temperatures.

Wednesday Forecast

7:27AM

DAYS 1-5 (JUNE 14-18)
High pressure brings beautiful mid June weather today and Thursday, and then it slides off to the east and a trough sits to the west Friday-Sunday, allowing humidity and the risk of showers to return.
TODAY: Mostly sunny. Highs 68-75, coolest East Coast. Wind N to NE 5-15 MPH.
TONIGHT: Mostly clear. Lows 48-56, coolest interior valleys. Wind light variable.
THURSDAY: Mostly sunny. Highs 72-78, coolest coast. Wind light variable with sea breezes.
FRIDAY: Partly cloudy. Isolated showers. Lows in the 50s. Highs in the 70s, coolest South Coast.
SATURDAY: Variably cloudy. Scattered showers and thunderstorms. Lows in the 60s. Highs in the 70s, coolest South Coast.
SUNDAY: Partly sunny. Isolated showers and thunderstorms. Lows in the 60s. Highs in the 80s, some 70s South Coast.

DAYS 6-10 (JUNE 19-23)
Humid and a shower/thunderstorm risk at times June 19-20, then a transition to drier weather follows. Temperatures near to above normal early in the period then near to below normal.

DAYS 11-15 (JUNE 24-28)
A more zonal pattern is still expected with a few episodes of showers/storms from passing disturbances and more variable temperatures.

Tuesday Forecast

7:15AM

DAYS 1-5 (JUNE 13-17)
One more hot day today but a cold front moving from north to south across the region may trigger a few showers and thunderstorm before it puts an end to the hot spell and high pressure behind it delivers seasonable weather for the middle of the week. When we get to the end of the week, a southerly flow will develop between high pressure exiting the East Coast and an approaching trough of low pressure from the west. This will increase the humidity and also the chance of showers and thunderstorms.
TODAY: Partly sunny. Isolated to scattered midday and afternoon thunderstorms possible southern NH and MA, and afternoon to early evening thunderstorms favoring MA/CT/RI. Humid. Highs 77-85 South Coast, 86-93 elsewhere. Wind W 5-15 MPH becoming variable with sea breezes especially South Coast, then shifting to N 5-15 MPH late. Strong winds possible near any storms.
TONIGHT: Partly cloudy. An isolated shower or thunderstorm favoring southern areas early. Lows 58-65. Wind N 5-15 MPH.
WEDNESDAY: Mostly sunny. Highs 68-75, coolest East Coast. Wind N to NE 5-15 MPH.
THURSDAY: Mostly sunny. Lows from the upper 50s to lower 50s. Highs in the 70s, coolest South Coast.
FRIDAY: Partly cloudy. Isolated showers. Lows in the 50s. Highs in the 70s, coolest South Coast.
SATURDAY: Variably cloudy. Scattered showers and thunderstorms. Lows in the 60s. Highs in the 70s, coolest South Coast.

DAYS 6-10 (JUNE 18-22)
Higher humidity and shower/thunderstorm chances are expected June 18-19 then a transition to drier weather follows. Temperatures near to above normal.

DAYS 11-15 (JUNE 23-27)
A more zonal pattern is still expected with a few episodes of showers/storms from passing disturbances and more variable temperatures.

Monday Forecast

7:42AM

DAYS 1-5 (JUNE 12-16)
The heat goes on today into Tuesday before a cold front puts an end to it after crossing the region from north to south during Tuesday. Today’s a rain-free, sunny day with increasing humidity, and the humidity remains into Tuesday providing some fuel for possible thunderstorms. It currently appears that the greatest threat for storms will be to the south of I-90 based on the timing of the front, a possible sea breeze boundary, a possible weak surface trough from the west just ahead of the front, and some cooler air aloft. It doesn’t look like a widespread storm outbreak for southern areas but a few strong storms are possible. By Wednesday, high pressure arrives via eastern Canada and lingers Thursday into Friday as it slides to the east eventually offshore. This will bring dry weather and lower humidity at first then some of the humidity may try to return by later Friday.
TODAY: Mostly sunny. More humid. Highs 77-87 South Coast, 88-95 elsewhere. Wind WSW 5-15 MPH with higher gusts.
TONIGHT: Mostly clear and hazy. Humid. Lows 66-74. Wind SW under 10 MPH.
TUESDAY: Partly sunny. Scattered afternoon thunderstorms favoring areas south of the Mass Pike. Humid. Highs 77-87 South Coast, 88-95 elsewhere. Wind W 5-15 MPH becoming variable with sea breezes especially South Coast, then shifting to N 5-15 MPH late. Strong winds possible near any storms.
WEDNESDAY: Mostly sunny. Lows from the upper 50s to middle 60s. Highs in the 70s, coolest East Coast.
THURSDAY: Mostly sunny. Lows from the upper 50s to lower 50s. Highs in the 70s, coolest South Coast.
FRIDAY: Partly cloudy. Lows in the 50s. Highs in the 70s, coolest South Coast.

DAYS 6-10 (JUNE 17-21)
Higher humidity and shower/thunderstorm chances are expected in the June 17-19 period before drier weather returns later in the period. Temperatures near to above normal.

DAYS 11-15 (JUNE 22-26)
A more zonal pattern returns with a few episodes of showers/storms from passing disturbances and more variable temperatures.

Sunday Forecast

12:17PM

DAYS 1-5 (JUNE 11-15)
Heatwave today through Tuesday for many locations except “the usual cool spots”. It all ends Tuesday as a cold front comes southward out of eastern Canada and is followed by a cooler high pressure area at midweek.
TODAY: Sunshine and high clouds. Highs 77-87 South Coast, 88-95 elsewhere. Wind W 10-20 MPH with higher gusts.
TONIGHT: Mostly clear. Lows 64-72. Wind WSW 5-15 MPH.
MONDAY: Mostly sunny. More humid. Highs 77-87 South Coast, 88-95 elsewhere. Wind WSW 5-15 MPH with higher gusts.
MONDAY NIGHT: Mostly clear and hazy. Humid. Lows 66-74. Wind SW under 10 MPH.
TUESDAY: Partly sunny. Hazy. Scattered afternoon thunderstorms. Humid. Highs 77-87 South Coast, 88-95 elsewhere. Wind W 10-20 MPH becoming variable to N late. Strong winds possible near any storms.
WEDNESDAY: Mostly sunny. Lows from the upper 50s to middle 60s. Highs in the 70s, coolest East Coast.
THURSDAY: Partly sunny. Lows from the middle 50s to lower 60s. Highs in the 70s, coolest South Coast.

DAYS 6-10 (JUNE 16-20)
Bermuda High set-up brings episodic scattered showers/thunderstorms but often rain-free, warm, and humid weather during this period.

DAYS 11-15 (JUNE 21-25)
A more zonal pattern returns with a few episodes of showers/storms from passing disturbances and more variable temperatures.

Saturday Forecast

7:39AM

DAYS 1-5 (JUNE 10-14)
A warm front moves across the region from west to east today and this will bring some clouds into the region during the day along with a spot shower or thunderstorm. Then the door to the heat will be open and will last for about 3 days, with many areas likely recording a heatwave before a cold front drops down from the north later Tuesday and brings cooler weather by Wednesday.
TODAY: Partly sunny. Isolated showers/thunderstorms mainly mid to late afternoon. Highs 68-75 coast, 76-82 elsewhere. Wind W 5-15 MPH.
TONIGHT: Partly cloudy. Lows 58-64. Wind WSW 5-15 MPH.
SUNDAY: Mostly sunny. Highs 77-86 South Coast, 87-95 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.
WEDNESDAY: Mostly sunny. Lows 57-64. Highs 70-80, coolest coast.

DAYS 6-10 (JUNE 15-19)
Evolving Bermuda High set-up will bring near to above normal temperatures, increased humidity, and a few opportunities for showers and thunderstorms during this period.

DAYS 11-15 (JUNE 20-24)
Indications are for a northwesterly flow to develop during this period bringing somewhat cooler weather and a few passing disturbances with brief rain chances.

Friday Forecast

7:20AM

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.

Thursday Forecast

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.

Wednesday Forecast

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.

Tuesday Forecast

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.

Monday Forecast

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.

Sunday Forecast

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.

Saturday Forecast

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.

Friday Forecast

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.

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.
