DAYS 1-5 (JUNE 15-19)

Low pressure gets to our east today and a little high pressure ridge sneaks in tonight into Friday. Enough cold air aloft today can support a couple isolated afternoon showers mainly across southern NH and northeastern MA, but for the most part the day will be dry for our region, including more sun eventually mixed with the clouds associated with the departing low pressure area. Friday should be a day that starts sunnier but ends with more clouds as the next trough and low will be on the approach. This is not good news for the weekend, especially Saturday, when upper low pressure goes right over us, and surface low pressure does a short cyclonic loop just south of us, bringing a cloudy and wet day with below normal temperatures. Only slight improvement is noted for Sunday as drier air arrives on the back side of that system which will start to move to the east. When we get to Monday it’s time for the start of a kind-of Rex block with high pressure in eastern Canada and a trough just to our southwest and south. We can still see showers around Monday with some chilly air above us and a weak disturbance in the area.

TODAY: Lots of clouds in portions of the region early to mid morning, otherwise a sun/cloud mix. An isolated shower possible southern NH and northern MA this afternoon. Highs 72-79, may be a little cooler in some coastal areas. Wind NW up to 10 MPH but coastal sea breeze are possible.

TONIGHT: Partly cloudy. Areas of fog. Lows 55-62. Wind W under 10 MPH.

FRIDAY: Sun gives way to clouds. Highs 75-82, cooler coast. Wind SW up to 10 MPH but again coastal sea breezes possible.

FRIDAY NIGHT: Mostly cloudy. Showers and thunderstorms arriving. Patchy fog. Lows 55-62. Wind variable up to 10 MPH.

SATURDAY: Cloudy. Periods of rain. Areas of fog and drizzle. Highs 58-65. Wind E 5-15 MPH.

SATURDAY NIGHT: Mostly cloudy. Chance of showers. Areas of fog and drizzle. Lows 51-58. Wind NE up to 10 MPH.

SUNDAY: Mostly cloudy to partly sunny. Chance of showers. Highs 67-74. Wind N up to 10 MPH.

SUNDAY NIGHT: Variably cloudy. Lows 55-62 Wind N under 10 MPH.

MONDAY: Variably cloudy. Chance of showers. Highs 68-75. Wind variable to E up to 10 MPH.

DAYS 6-10 (JUNE 20-24)

Rex block pattern for a few days with high pressure strong enough to keep wet weather to the south, but the break down of the pattern may allow wet weather to push back into the region late in the period. Temperatures near to below normal.

DAYS 11-15 (JUNE 25-29)

Flip to a more zonal flow pattern with a couple shower chances, and “warmer” weather, but no major heat.

DAYS 1-5 (JUNE 14-18)

Two low pressure systems will impact our weather over the next 5 days. The first brings a shower and thunderstorm threat later today / tonight, but the greatest threat of severe storms is going to occur to our west and northwest, away from the influence of a stabilizing southerly wind off the ocean water to the south, and where there is a better combo of dynamics / heating. However, can’t rule out some stronger storms further east especially this evening before things quiet down later tonight. The first low gets to our east Thursday but enough cold air lingers aloft that a few pop up showers and maybe even an isolated thunderstorm can occur, favoring southern and central to eastern MA, later in the afternoon or early evening. Friday’s weather will hold another shower and thunderstorm chance in the afternoon and evening as another low pressure area moves toward the area from the west. This low likely stacks with its upper level partner and temporarily slows down enough to mess up at least part of the weekend. Indications are for a mainly cloudy and damp Saturday with some rainfall around – maybe not all day but enough to alter many outdoor plans, then some improvement but still the chance of diurnal shower development on Sunday. Temperatures will be a little closer to normal today through Friday before cooling back to below normal during the coming weekend.

TODAY: Low overcast and areas of fog east central and northeastern MA to southeastern NH early otherwise a sun/cloud mix with clouds taking over late. Late-day and evening showers and thunderstorms probable in the region – any storms can be strong to locally severe, favoring western areas. Highs 75-82. Wind S 5-15 MPH. Winds can be variable, strong, and gusty near any storms.

TONIGHT: Mostly cloudy with showers and thunderstorms likely evening – any thunderstorms potentially severe. Partly cloudy with areas of fog overnight. Lows 58-65. Wind variable to W up to 10 MPH. Winds can be briefly strong and gusty near any storms.

THURSDAY: Partly sunny. Isolated afternoon showers and a possible thunderstorm, favoring southern NH and eastern MA mid afternoon on. Highs 72-79. Wind W 5-15 MPH.

THURSDAY NIGHT: Partly cloudy. Areas of fog. Lows 55-62. Wind W under 10 MPH.

FRIDAY: Variably cloudy. Scattered to numerous afternoon showers and thunderstorms. Highs 71-78. Wind SW 5-15 MPH.

FRIDAY NIGHT: Mostly cloudy. Chance of showers. Areas of fog and drizzle. Lows 55-62. Wind variable under 10 MPH.

SATURDAY: Mostly cloudy. Showers likely. Areas of fog and drizzle. Highs 62-69. Wind E-NE up to 10 MPH.

SATURDAY NIGHT: Mostly cloudy. Chance of showers. Areas of fog and drizzle. Lows 55-62. Wind NE up to 10 MPH.

SUNDAY: Partly sunny. Chance of showers. Highs 67-74. Wind N up to 10 MPH.

DAYS 6-10 (JUNE 19-23)

Current leaning for next week is a Rex block pattern with high pressure close enough for mainly dry weather, keeping unsettled weather to our south. This is a drier pattern with no major heat.

DAYS 11-15 (JUNE 24-28)

Wet weather early in the period introduces a more zonal pattern with more seasonable temperatures and a couple shower/thunderstorm chances.

DAYS 1-5 (JUNE 13-17)

The larger scale pattern features continued domination by upper level low pressure over our region, with one moving from the Great Lakes across New England through early Thursday, exiting, and being replaced by a follow-up Friday into the start of the weekend. For our region this means continued unsettled weather. It doesn’t rain all the time, but there are daily opportunities for showers, some more substantial than others. While it doesn’t look it when you start the day today, this is an improvement day, but it will be somewhat subtle. We start our with a few lingering sprinkles but a thick overcast with areas of fog and drizzle, but a dry slot will be working in as surface low pressure lifts away from the region. This will help begin a clearing process, so the clouds will thin and break, but complete clearing is likely be prevented by a southeast to east air flow at the surface. Some partial clearing but patchy fog redevelopment is expected tonight, and clouds will become dominant again Wednesday with the approach of the next surface disturbance around the upper low. This one carries dynamics to produce more potent showers and thunderstorms in the afternoon and evening, with a low but present risk of severe thunderstorms occurring, so we’ll have to keep a close eye on the evolution of the weather tomorrow. This system exits by early Thursday as the upper low starts to pull out, so while the cold air lingering aloft still allows for a shower chance, the activity will be quite limited due to a drying process both at low and mid levels of the atmosphere. This doesn’t last long, as both the next upper and surface lows approach on Friday with an increased chance of showers and possible thunderstorms once again. The forecast for Saturday is a little lower confidence due to the difficulty in trying to forecast upper low departure to begin with, and the inconsistency of guidance designed to help the effort. Right now, I feel the upper low and a surface low will be close enough for a damp early Saturday followed by drying, but any solar heating helping scattered showers to pop up, so in summation, an unsettled day at best.

TODAY: Cloudy with a few showers and areas of drizzle and fog to start, then breaking clouds at times with only a slight chance of a brief shower. Highs 68-75. Dew point 60+ at least through midday may drop later. Wind SE 5-15 MPH.

TONIGHT: Variably cloudy. Areas of fog. Lows 55-62. Wind variable under 10 MPH,.

WEDNESDAY: Variably cloudy. Showers/thunderstorms likely later in the day. Any storms can be strong to locally severe. Highs 73-80. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy with showers and thunderstorms in the evening, then breaking clouds but areas of fog. Lows 58-65. Wind W 5-15 MPH.

THURSDAY: Partly sunny. Isolated afternoon showers. Highs 72-79. Wind W 5-15 MPH.

THURSDAY NIGHT: Partly cloudy. Areas of fog. Lows 55-62. Wind W under 10 MPH.

FRIDAY: Variably cloudy. Scattered afternoon showers and thunderstorms. Highs 71-78. Wind W 5-15 MPH becoming variable.

FRIDAY NIGHT: Mostly cloudy. Chance of showers. Areas of fog and drizzle. Lows 55-62. Wind variable under 10 MPH.

SATURDAY: Cloudy start with areas of drizzle and fog, then breaking clouds and partial sun but also a chance of showers. Highs 68-75. Wind variable to N up to 10 MPH.

DAYS 6-10 (JUNE 18-22)

Upper level low pressure still close enough for a shower chance June 18. Evolution of pattern after that looks like a temporary Rex block with high pressure across eastern Canada into the New England region with a drying trend while low pressure gets pushed to the south – but must keep an eye on it as it won’t be far away. Despite drying, any warm up will be modest.

DAYS 11-15 (JUNE 23-27)

Not a high confidence forecast but signs of a rather quick Rex block break down and switch to a zonal flow pattern with a weak mean trough in the Great Lakes and Northeast. Resultant weather is a couple shower/t-storm chances and no major heat for the first days of summer.

DAYS 1-5 (JUNE 12-16)

Another week / another upper low. Yes once again our weather for the balance of the coming week will be governed by upper level low pressure. Initially this upper low will be to our west a little longer than the last one, and we’ll be in a southwesterly air flow ahead of it through Wednesday. During this time, two main disturbances will impact our weather, the first tonight into Tuesday in the form of a frontal system parented from surface low pressure passing to our northwest. The warm front will move into and through the region tonight with some showers and possibly a thunderstorm, followed by its cold front early Tuesday with additional showers and a few storms possible, but this front will be in the process of dissipating as it runs out of push, becoming parallel to the air flow and the air mass behind it modifying to very similar to what’s ahead of it. Some clearing will occur later Tuesday as a swath of drier air moves in. The next disturbance rotating around the upper low will bring another shot at showers and thunderstorms Wednesday, mainly in the afternoon and evening, and pending the timing and heating ahead of these, some may be strong to severe. I’ll need to fine-tune that through tomorrow’s updates/comments. Thursday’s a quieter day but can’t rule out a pop up shower as the upper low moves eastward and we’re under its cold pool, and this will be the case Friday as well with a better shot at pop up showers and even a few thunderstorms with the aid of an additional disturbance moving through.

TODAY: Mostly cloudy to partly sunny. Highs 68-75 South Coast, 75-82 elsewhere. Dew point around or just over 60. Wind S 5-15 MPH.

TONIGHT: Cloudy. Showers likely and a possible thunderstorm late evening on. Areas of fog overnight. Lows 60-67. Dew point near or just over 60. Wind S 5-15 MPH.

TUESDAY: Cloudy with showers likely and possibly a thunderstorm early, then mostly cloudy with isolated to scattered showers through midday. Clearing with more sun late. Highs 68-75. Dew point 60+ at least through midday may drop later. Wind S-SW 5-15 MPH.

TUESDAY NIGHT: Variably cloudy. Lows 55-62. Wind SW 5-15 MPH.

WEDNESDAY: Variably cloudy. Showers/thunderstorms likely later in the day. Any storms can be strong to locally severe. Highs 73-80. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy with showers and thunderstorms in the evening, then breaking clouds but areas of fog. Lows 58-65. Wind W 5-15 MPH.

THURSDAY: Partly sunny. Isolated afternoon showers. Highs 72-79. Wind W 5-15 MPH.

THURSDAY NIGHT: Partly cloudy. Areas of fog. Lows 55-62. Wind W under 10 MPH.

FRIDAY: Variably cloudy. Scattered afternoon showers and thunderstorms. Highs 71-78. Wind W 5-15 MPH.

DAYS 6-10 (JUNE 17-21)

The June 17-18 weekend will still feature upper level low pressure, though it will be slowly exiting and weakening, but there can still be a few pop up showers around each day. A brief break, then the next disturbance ends spring and ushers in summer with a chance of showers later in the period.

DAYS 11-15 (JUNE 22-26)

A general west to east flow, lack of blocking, but tendency for troughing still to be in place, bringing a couple unsettled weather chances but keeping major heat away.

DAYS 1-5 (JUNE 11-15)

People often react like weather patterns that they don’t like last forever. Well, they don’t. And even the general pattern of cool and more recently quite unsettled weather won’t last forever, but for now, we’re still not done with it. The same general pattern dominates, but there are breaks, like today. We have a small ridge of high pressure traversing the region to provide a dry, warmer day today. It’s not going to be “summer hot” but it will be quite nice for many to be outside, between that “it’s too cool” and “it’s too hot” feel. Enjoy if you can, it doesn’t last. Another upper low is heading this way and will dominate our weather from later Monday through midweek. First it brings a showery episode Monday night into Tuesday morning then occasional shower episodes later Tuesday and another later Wednesday. When we get to Thursday, we’ll be under a cold pool aloft with just some diurnal pop up shower activity, similar to what we saw the last couple days.

TODAY: Mostly sunny through midday then increasing clouds thereafter. Highs 73-80, coolest coast. Wind W up to 10 MPH, but some coastal sea breezes likely.

TONIGHT: Mostly cloudy. Lows 55-62. Wind S up to 10 MPH.

MONDAY: Mostly cloudy. Highs 72-79, coolest South Coast. Wind S 5-15 MPH.

MONDAY NIGHT: Cloudy. Showers likely and a possible thunderstorm late evening on. Areas of fog overnight. Lows 60-67. Wind S 5-15 MPH.

TUESDAY: Cloudy with showers likely and possibly a thunderstorm early, then mostly cloudy with isolated to scattered showers. Highs 68-75. Dew point above 60. Wind S 5-15 MPH.

TUESDAY NIGHT: Variably cloudy. Lows 55-62. Wind SW 5-15 MPH.

WEDNESDAY: Partly sunny morning-midday. Mostly cloudy later in the day with showers likely and possibly a thunderstorm. Highs 70-77. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy with showers in the evening, then breaking clouds but areas of fog. Lows 58-65. Wind W 5-15 MPH.

THURSDAY: Partly sunny. Isolated to scattered showers and possibly a thunderstorm. Highs 68-75. Wind W 5-15 MPH.

DAYS 6-10 (JUNE 16-20)

No major pattern changes as we head through the final 5 days of spring, but after a few diurnal showers June 16, the timing may be such that a stretch of fair weather coincides with the June 17-18 weekend before the next trough and shower chance arrives.

DAYS 11-15 (JUNE 21-25)

Just in time for summer, the blocked nature of the large scale pattern breaks down, but the general pattern is likely to be troughs on both coasts and ridge in the central USA (the forecast of the general pattern for the first part of summer). This would mean more seasonable weather but still some shower chances, and no major heat, for our region.

DAYS 1-5 (JUNE 10-14)

The temperature and dew point met each other overnight in many areas, causing areas of fog, some of it quite dense. Fog and stratus linger mainly in the eastern MA coastal plain as of mid morning but will be mixing out soon as solar heating works on it. We have one more day under the influence of the upper low that’s been around all week, but today’s impact will be far less than yesterday’s in the vast majority of the region. The exception will be any areas that happen to be hit by a passing shower or thunderstorm, which will be more isolated today, but possible at any time – with a tendency for most of them to occur in the noon to 6 p.m. window. Once again any of these could produce small hail, but it’s important to stress that these occurrences will be far more isolated than yesterday’s activity, so outdoor plans should be largely a “go” with just the need to keep an eye out for a shower or storm and have a plan of action in case. Tonight we should only see patchy ground fog form, and it will be a quiet night though some clouds will linger. Sunday’s the “pick” of the week and the weekend as well – the nicest day with the most sun, weighted toward the first half to 2/3 of the day before we see clouds from the next approaching trough start to move in. Some short range guidance has indicated a shower threat later Sunday for interior locations in response to warm air advection, but my emphasis is on increasing clouds and not much of a shower threat, so I am leaving that out of the forecast. It doesn’t get left out of the forecast for early in the week though, when warm frontal rain is probable on Monday and cold frontal showers, some heavy, will be around Monday night into Tuesday as surface low pressure heads through the Great Lakes and a weak secondary low forms to our south and moves up across the region. A dry slot may work in during Tuesday and cut off the shower threat for a number of hours, but these details can be refined with the help of short-range guidance in the next few days. By the time we get to Wednesday, we’re back underneath an upper level low with a cold pool aloft and more diurnal shower development as the same weather pattern rolls on.

TODAY: Low clouds/fog linger into mid morning eastern MA coastal plain, otherwise clouds give way to a sun/cloud mix. Isolated showers and possible thunderstorms, favoring the afternoon, and any can produce small hail. Highs 68-75. Wind variable up to 10 MPH early, becoming N 5-15 MPH, then locally E along eastern coastal areas of NH and MA during the afternoon.

TONIGHT: Partly to mostly cloudy. Patchy ground fog in lower elevations. Lows 50-57. Wind variable under 10 MPH.

SUNDAY: Mostly sunny through midday then increasing clouds thereafter. Highs 73-80, coolest coast. Wind W up to 10 MPH, but some coastal sea breezes likely.

SUNDAY NIGHT: Mostly cloudy. Lows 55-62. Wind S up to 10 MPH.

MONDAY: Mostly cloudy. Chance of rain at times in the afternoon. Highs 70-77, coolest South Coast. Wind S 5-15 MPH.

MONDAY NIGHT & TUESDAY: Mostly cloudy with showers likely. Areas of fog. More humid with dew point temperatures above 60 becoming likely. Lows 60-67. Highs 68-75. Wind S to SW 10-20 MPH but may becoming variable at times.

TUESDAY NIGHT: Variably cloudy. Lows 55-62. Wind SW 5-15 MPH.

WEDNESDAY: Partly sunny. Isolated to scattered mainly afternoon showers and possible thunderstorms. Highs 68-75. Wind SW 5-15 MPH.

DAYS 6-10 (JUNE 15-19)

Upper level low pressure continues to cause mainly diurnal shower chances especially the first part of the period before it lifts out to a more westerly air flow with less shower chances later in the period. Temperatures below to near normal.

DAYS 11-15 (JUNE 20-24)

Weak westerly flow overall but tendency for low pressure trough to dominate with a couple shower chances and no major heat in sight as we welcome Summer 2023 (solstice June 21).

DAYS 1-5 (JUNE 9-13)

Today is the day that the upper low that’s been in our region for days starts its exit, but we’ll still be under its cold pool, which makes the atmosphere unstable. Solar heating triggers the development of scattered showers and thunderstorms this afternoon, and two sea breeze boundaries can focus some of the activity in a couple areas. The first of these is the South Coast sea breeze which may try to orient convection in a west-east line south of I-90 by mid to late afternoon, and a smaller version of this in a north-south line can occur near the MA North Shore and NH Seacoast later in the day. Otherwise, look for the popcorn variety showers elsewhere in the region. Note: Any of these showers can grow enough to produce lightning and small hail, hence the inclusion of thunderstorms and frozen ice ball potential in the detailed forecast that appears below. This activity will fade with the setting sun, but with some lingering around with clearer sky in dry air between showers, I’ll have to issue a rainbow watch for this evening! This type of pattern / set-up results in rather picturesque skies if we are not overtaken by too much overcast, so camera people, keep an eye out for that! As far as wildfire smoke goes, the lower level plume has been pushed just to our south but the northern portion of that may get back into the South Coast region with the development of a sea breeze during the day today. Thin upper level smoke may be around Saturday while the surface smoke plume is pushed to the south again in a more northerly air flow. Upper level low pressure exits to the east on Saturday, but we’ll be on the western edge of its cold pool sufficiently enough for solar heating to trigger another round of showers and possible thunder/hail, but this time in isolated form and more likely confined to the I-95 belt eastward and during the hours of 11 a.m. to 5 p.m., before support is lost and any left vanish. This leaves Saturday night and Sunday free of any rainfall threat as a weak ridge of high pressure builds in and moves across the region. Some smoke can return on Sunday from the west northwest at high levels and the southwest at the surface, especially in southern portions of the region, but right now it does not look as thick as what we saw at the peak of the event recently. Sunday’s temperatures will be the warmer of the 2 weekend days, but not “hot”. Heading into early next week, we return to our unsettled weather regime as the next trough of low pressure moves in from the west. Initially, a warm front approaches Monday with clouds and wet weather chances going up. Low pressure development to our south then has to track northward on the eastern side of the approaching upper trough and has the chance to bring a swath of significant rainfall sometime later Monday into a portion of Tuesday along with muggier air than we’ve had to deal with for a while. Although once again, temperatures will trend to below normal so when you hear the term “muggy” or “humid”, don’t automatically assume heat goes with it, because it won’t be this time either.

TODAY: Partly sunny. Scattered afternoon showers and possible thunderstorms, with most activity occurring after 2 p.m. Any storms can produce small hail. Highs 64-71. Wind variable up to 10 MPH with coastal sea breezes, but any heavier showers/storms can produce variable, briefly gusty wind.

TONIGHT: Partly cloudy. Chance of a shower early. Lows 48-55. Wind W up to 10 MPH.

SATURDAY: Partly cloudy. Isolated showers and a possible thunderstorm midday to mid afternoon, favoring NH Seacoast and eastern MA. Highs 68-75. Wind variable up to 10 MPH early, becoming N 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 50-57. Wind NW under 10 MPH.

SUNDAY: Mostly sunny. Highs 72-79, coolest coast. Wind W up to 10 MPH, may be some coastal sea breezes.

SUNDAY NIGHT: Increasing clouds. Lows 53-60. Wind S up to 10 MPH.

MONDAY: Mostly cloudy. Chance of rain at times in the afternoon. Highs 70-77, coolest South Coast. Wind S 5-15 MPH.

MONDAY NIGHT & TUESDAY: Mostly cloudy with showers likely. Areas of fog. More humid with dew point temperatures above 60 becoming likely. Lows 60-67. Highs 68-75. Wind S to SW 10-20 MPH but may becoming variable at times.

DAYS 6-10 (JUNE 14-18)

Upper level low pressure crosses the region midweek next week with diurnal shower chances and below normal temperatures expected. Upper low exits with more of a westerly air flow and a drier, milder trend late week. Also of importance is that the outlook is for some beneficial rain to visit both major fire areas in Canada next week, lessening smoke coming from those source regions and therefore drastically reducing the chances of smoke both surface and aloft having to be part of the day-to-day forecast.

DAYS 11-15 (JUNE 19-23)

Overall pattern favors a weak low pressure trough in a more zonal and less blocked pattern with a couple opportunities for showers/thunderstorms, but mainly fair weather and temperatures below to near normal. The summer solstice occurs on June 21.

DAYS 1-5 (JUNE 8-12)

Upper level low pressure wobbles around for a couple more days, completing a cyclonic loop moving westward to southwest today into Friday then eastward and starting to move away from the region on Saturday. These 3 days carry shower chances but they differ slightly. Today is the coolest and cloudiest and “most stable” with limited showers and very little chance that any could build to produce thunderstorms. Friday is a more unstable day with scattered mainly afternoon activity capable of producing thunder and small hail, and Saturday this chance continues but coverage reduces to isolated and favoring eastern MA and RI for a portion of the afternoon before support is lost. High pressure builds in for a nice Sunday. Another low pressure trough approaches Monday with a return to unsettled weather at that time, though it may be a slow process with a shower threat holding off until later in the day. We can still see some plumes of both low and high altitude smoke at times over the coming days from Canadian wildfires.

TODAY: Mostly cloudy. Isolated to scattered showers. Highs 61-68. Wind NW up to 10 MPH.

TONIGHT: Mostly cloudy. Lows 48-55. Wind WNW up to 10 MPH.

FRIDAY: Partly sunny. Scattered afternoon showers and possible thunderstorms, favoring areas away from the coast. Any storms can produce small hail. Highs 64-71. Wind variable up to 10 MPH with coastal sea breezes.

FRIDAY NIGHT: Partly cloudy. Chance of a shower early. Lows 48-55. Wind W up to 10 MPH.

SATURDAY: Partly cloudy. Isolated showers and a possible thunderstorm midday to mid afternoon, favoring eastern MA and RI. Highs 68-75. Wind variable up to 10 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 50-57. Wind NW under 10 MPH.

SUNDAY: Mostly sunny. Highs 72-79, coolest coast. Wind W up to 10 MPH, may be some coastal sea breezes.

SUNDAY NIGHT: Increasing clouds. Lows 53-60. Wind S up to 10 MPH.

MONDAY: Mostly cloudy. Chance of showers later in the day. Highs 70-77, coolest South Coast. Wind S 5-15 MPH.

DAYS 6-10 (JUNE 13-17)

Large scale pattern again dominated by a low pressure trough with unsettled weather at times, especially early and again late in the period. Temperatures near to below normal.

DAYS 11-15 (JUNE 18-22)

Still a tendency for more trough than ridge at upper levels but relaxing a little so that we’re drier overall and temperatures are more seasonable.

DAYS 1-5 (JUNE 7-11)

The same old story … upper level low pressure in control. It stays this way until the weekend, when the one over us now finally moves away. Before that, we have a few more unsettled days to go through with shower threats. None of these are “rainy” days, but all contain the chance of rain at some point for at least parts of our region. The upper level low with its center currently to our northeast elongates east-west today then the western lobe begins to drift southward across the region by Thursday and into Friday as the low then reconfigures to more of a symmetrical round shape, centered right across eastern New England and the Gulf of Maine by early Friday, after which it will begin a drift to the east with the last of its effect departing on Saturday. Today’s shower threat comes to northern areas from mid level moisture associated directly with the elongating low, with a swath of wet weather already taking place as I write this in south central and southeastern NH to northeastern MA. Enough solar heating takes place before that to fire up some diurnal showers especially in MA which will move to the southeast, fading later on as the solar fuel diminishes. These will not be widespread for coverage, but can be moderate to briefly heavy where they do occur. You’ll also notice that our thick smoke plume from yesterday is less so as it gets pushed to the south, although it may hang on in CT longer. The plume should then be kept mostly out of the region by the upper low into late week. Another round of diurnal shower development takes place Thursday, and with a little more northeast-southwest orientation of upper low and resultant mid level southwest wind over our area, we may see one or two broken lines of showers and embedded thunderstorms in the region. The threat will be a little higher in southeastern MA tomorrow over today, but they can occur anywhere else in the region as well depending on where the initial development takes place. Another region vulnerable may favor northeastern CT, central MA, and southern NH with tomorrow’s activity, with a late-day fading of activity again. Friday, with the core of the cold air aloft right over us, you’d think that the showers and storms could pop anywhere and everywhere, but at the surface with light winds we may develop a moderate sea breeze which may have a stabilizing influence at least in the coastal plain, keeping shower activity limited or even prevented, with activity focusing more on the inland hilly terrain from southwestern NH through central MA into northeastern CT and northwestern RI. Will monitor this trend on short range guidance. Of diurnal shower/storm development the next 3 days, Friday’s has the greatest chance to produce hail where it occurs. Saturday looks “better” but enough cold air will remain over the region on the western edge of the departing low that we will at least pop some clouds and maybe a few more showers, but these should be limited and may peak quickly around midday. I’ll have to fine-tune that part of the forecast as we get closer to it. By Sunday, that upper low is gone and we’re in a weak ridge of high pressure between it and the next approaching trough, so we get a very nice day. But the next trough may already be spreading high and mid level clouds in by later in the day, so we may not end up with a completely sunny day Sunday.

TODAY: Smoke-filtered sun southern MA southward early, brighter sun just to the north, and thicker clouds northeastern MA and southern NH with showers into mid morning. Afterward variably cloudy with scattered midday and afternoon showers favoring MA but possible anywhere. Highs 61-68. Wind NW 5-15 MPH.

TONIGHT: Lots of clouds. Maybe a shower early. Lows 48-55. Wind NW up to 10 MPH.

THURSDAY: Variably cloudy. Chance of showers and possibly a thunderstorm. Highs 61-68. Wind WNW 5-15 MPH.

THURSDAY NIGHT: Partly cloudy. Lows 47-54. Wind WNW 5-15 MPH.

FRIDAY: Partly sunny. Scattered afternoon showers and possible thunderstorms, favoring areas away from the coast. Any storms can produce small hail. Highs 62-69. Wind variable up to 10 MPH with coastal sea breezes.

FRIDAY NIGHT: Partly cloudy. Chance of a shower early. Lows 48-55. Wind W up to 10 MPH.

SATURDAY: Partly cloudy. Chance of a few midday showers favoring the eastern coastal plain. Highs 67-74. Wind variable to W up to 10 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 50-57. Wind NW under 10 MPH.

SUNDAY: Sunshine. Increasing clouds later. Highs 70-77, coolest coast. Wind W up to 10 MPH, may be some coastal sea breezes.

DAYS 6-10 (JUNE 12-16)

Large scale pattern again dominated by a low pressure trough with unsettled weather weighted toward the first half of next week. Temperatures near to below normal.

DAYS 11-15 (JUNE 17-21)

Still a tendency for more trough than ridge at upper levels but relaxing a little so that we’re drier overall and temperatures are more seasonable.

DAYS 1-5 (JUNE 6-10)

Upper level low pressure continues its reign over our weather, but with a variety of weather dependent on the configuration of the low and associated surface systems. Today, a northwesterly air flow first brings in a significant plume of wildfire smoke (already here as of very early morning) that filters the sun we get, and is even concentrated enough at the surface to be detectable by smell. It also results in a reduction of air quality. The sun, despite a smoke filter, will be enough to trigger scattered showers and thunderstorms in the unstable atmosphere this afternoon. Tonight, those end and the smoke plume gets pushed away to the south as the wind flow turns more northerly again, and this will be the theme for mid to late week. Spokes of energy around the upper low will still bring shower chances each day Wednesday through Friday. The Wednesday and Thursday activity will be patchy light rain areas and Friday’s will be more like today’s in a more unstable atmosphere, with pop up showers and a few thunderstorms too. Saturday, we will start to lose upper low finally, as it drifts away to the east, leaving us with just some lingering fair-weather clouds and only the slightest chance of a brief shower in isolated locations.

TODAY: Smoke-filtered sun joined by developing clouds midday onward. Scattered showers and isolated thunderstorms this afternoon, with any heavier showers/storms capable of producing hail and briefly gusty wind. Best chance of storms central to southeastern MA, eastern CT, and RI. Highs 68-75. Wind NW 5-15 MPH, variable and gusty around some storms.

TONIGHT: Partly to mostly cloudy. An evening shower or thunderstorm possible mainly in central MA to northeastern CT and northern RI. Lows 48-55. Wind NW-N 5-15 MPH.

WEDNESDAY: Mostly cloudy. Chance of showers. Highs 60-67. Wind NW 5-15 MPH.

WEDNESDAY NIGHT: Variably cloudy. Chance of showers. Lows 47-54. Wind NW 5-15 MPH.

THURSDAY: Variably cloudy. Chance of showers. Highs 61-68. Wind WNW 5-15 MPH.

THURSDAY NIGHT: Partly cloudy. Lows 47-54. Wind WNW 5-15 MPH.

FRIDAY: Partly sunny. Scattered afternoon showers and possible thunderstorms. Highs 62-69. Wind W 5-15 MPH.

FRIDAY NIGHT: Partly cloudy. Chance of a shower early. Lows 48-55. Wind W up to 10 MPH.

SATURDAY: Partly cloudy. Remote chance of a passing shower. Highs 68-75. Wind W 5-15 MPH.

DAYS 6-10 (JUNE 11-15)

High pressure brings dry weather to finish off the weekend on June 11. Another stretch of unsettled weather takes place early to middle of next week as another upper low moves in along with a cooling trend again.

DAYS 11-15 (JUNE 16-20)

The final days of astronomical spring will hold a similar pattern, governed by a low pressure trough, a few shower chances, and near to below normal temperatures.

DAYS 1-5 (JUNE 5-9)

Upper level low pressure continues to dominate our weather and will do so through Friday, though easing its grip as it starts its exit eastward late week. Today will be the wettest day in terms of the amount of hours of rainfall for the region as a whole, with surface low pressure making its closest pass this morning on the westward extent of a cyclonic loop off the Northeast Coast. This brings a swath of rainfall across the region this morning to midday, but it diminishes to just a few isolated showers / sprinkles this afternoon as drier air works in from the north, which is also when we can see some sunbreaks through the cloud cover. It will also be another day of below normal temperatures with a chilly northerly wind, but not quite as “cold” as the weekend was. We warm up a little Tuesday with surface low pressure far enough away and a weaker air flow as well as a little dry air in place to allow for some clearing and therefore additional solar heating, but as another disturbance enters the upper level low over our area from the northwest, accompanied by a surface cold front, there will be the development of showers and possible thunderstorms during the afternoon, and these can produce some gusty winds and small hail. It appears the greatest chance for these will take place in western and southern portions of the forecast area but they are possible anywhere. In addition to the shower and storm threat, some of the smoke from a series of wildfires in Quebec will be in the atmosphere, and some at a low enough level to detect by smell and lower the air quality to borderline unhealthy levels. The irregularly shaped upper low and another loop of surface low pressure back to the west will send more substantial cloudiness and cooler air back into the region for midweek along with a continue chance of occasional showers occurring, but will also push some of the smoke out, improving the air quality. While the shower threat continues Friday, it will lessen as low pressure at both the surface and upper levels finally begins to pull away to the east as the blocking pattern relaxes slightly.

TODAY: Cloudy morning with widespread showers eastern areas and occasional showers to the west. Mostly cloudy this afternoon with scattered to isolated showers favoring eastern areas. Highs 57-64. Wind N 5-15 MPH, higher gusts.

TONIGHT: Mostly cloudy. Chance of a shower early, favoring eastern areas. Lows 46-53. wind N 5-15 MPH.

TUESDAY: Variably cloudy. Scattered showers and possible thunderstorms in the afternoon, most numerous southwestern NH, central MA, eastern CT, and RI. Any showers or storms can produce small hail and briefly gusty wind. Smoke from Canada may reduce visibility and be detectable by smell. Highs 68-75. Wind NW 5-15 MPH.

TUESDAY NIGHT: Partly to mostly cloudy. An evening shower possible. Lows 48-55. Wind NW-N 5-15 MPH.

WEDNESDAY: Mostly cloudy. Chance of showers. Highs 60-67. Wind NW 5-15 MPH.

WEDNESDAY NIGHT: Variably cloudy. Chance of showers. Lows 47-54. Wind NW 5-15 MPH.

THURSDAY: Partly sunny. Chance of showers. Highs 61-68. Wind WNW 5-15 MPH.

THURSDAY NIGHT: Partly cloudy. Lows 47-54. Wind WNW 5-15 MPH.

FRIDAY: Partly cloudy. Chance of a shower. Highs 62-69. Wind W 5-15 MPH.

DAYS 6-10 (JUNE 10-14)

High pressure briefly controls the weather with fair, milder conditions for the June 10-11 weekend before upper level low pressure returns an unsettled pattern with near to below normal temperatures early next week.

DAYS 11-15 (JUNE 15-19)

Overall pattern somewhat unsettled and on the cooler side of normal overall with upper level low pressure in control most of the time.

DAYS 1-5 (JUNE 4-8)

Upper level low pressure remains in control, bringing us an unsettled and cool weather pattern into the middle of the coming week. Surface low pressure offshore wheels some of its showers into the region, especially eastern sections, today into Monday, and another disturbance enters the trough from the northwest with additional showers Tuesday into midweek.

TODAY: Mostly cloudy with isolated to scattered showers NH Seacoast and eastern MA to RI this morning. Cloudy with scattered to numerous showers similar areas this afternoon. Areas of drizzle mainly eastern coastal plain. Highs 53-60, coolest eastern coastal areas. Wind N 10-20 MPH, higher gusts.

TONIGHT: Cloudy. Showers likely, especially southeastern NH, eastern MA, and RI. Lows 45-52. Wind N 5-15 MPH, higher gusts.

MONDAY: Cloudy morning with showers likely, especially eastern areas. Mostly cloudy afternoon with a possible passing shower. Highs 56-63. Wind N 10-20 MPH.

MONDAY NIGHT: Mostly cloudy. Chance of showers in the evening. Lows 45-52. Wind N-NW 5-15 MPH.

TUESDAY: Mostly cloudy. Showers likely, especially in the afternoon. Highs 58-65. Wind N-NW 5-15 MPH.

TUESDAY NIGHT: Mostly cloudy. Chance of shower, especially evening. Lows 47-54. Wind NW 5-15 MPH.

WEDNESDAY: Mostly cloudy. Chance of showers. Highs 60-67. Wind NW 5-15 MPH.

WEDNESDAY NIGHT: Variably cloudy. Chance of showers. Lows 47-54. Wind NW 5-15 MPH.

THURSDAY: Partly sunny. Chance of showers. Highs 61-68. Wind W 5-15 MPH.

DAYS 6-10 (JUNE 9-13)

Upper low pressure departs and is replaced by high pressure with fair weather and a warm up toward normal temperatures June 9-11 before another round of unsettled weather and a cool-down as the next trough drops into the region from the northwest later in the period.

DAYS 11-15 (JUNE 14-18)

Similar pattern, may be fair early then additional shower chances follow. Temperatures near to below normal.

DAYS 1-5 (JUNE 3-7)

Our weather will be governed by upper level low pressure this weekend and into next week as well. Within this unsettled and cool stretch there will be variations due to position of upper low and also surface features. The upper low will drift southwestward initially this weekend from the St. Lawrence Valley to just east of New England, then south to southeast a little further east and southeast of the region early to mid week. While we have some drizzle and very light showers around to start today with lingering low level moisture, we’ll have some drier air work in to limit or put an end to any precipitation as the day goes on. But surface low pressure evolving offshore will make a cyclonic loop, close enough to bring occasional showers into the region, favoring the eastern portion, Sunday and Monday, best chance Sunday afternoon to Monday morning. As the system then starts another cyclonic loop further east, we’ll get into a more northwesterly flow by Tuesday and Wednesday, but still carrying shower chances, especially Tuesday with the aid of a new disturbance moving in via Canada. So the summation is unsettled and cool for quite a while…

TODAY: Cloudy morning with areas of drizzle and a few light showers. Mostly cloudy afternoon with any breaks of sun more likely well inland. Highs 53-60, coolest eastern coastal areas. Wind NE 5-15 MPH, higher gusts.

TONIGHT: Mostly cloudy. Chance of a passing shower. Lows 45-52. Wind NE-N 5-15 MPH.

SUNDAY: Mostly cloudy morning. Cloudy afternoon with an increased chance of showers, especially southeastern NH, eastern MA, and RI. Areas of drizzle mainly eastern coastal plain. Highs 53-60, coolest eastern coastal areas. Wind N 10-20 MPH, higher gusts.

SUNDAY NIGHT: Cloudy. Showers likely, especially southeastern NH, eastern MA, and RI. Lows 45-52. Wind N 5-15 MPH, higher gusts.

MONDAY: Cloudy morning with showers likely, especially eastern areas. Mostly cloudy afternoon with a possible passing shower. Highs 56-63. Wind N 10-20 MPH.

MONDAY NIGHT: Mostly cloudy. Chance of showers in the evening. Lows 45-52. Wind N-NW 5-15 MPH.

TUESDAY: Mostly cloudy. Showers likely, especially in the afternoon. Highs 58-65. Wind N-NW 5-15 MPH.

TUESDAY NIGHT: Mostly cloudy. Chance of shower, especially evening. Lows 47-54. Wind NW 5-15 MPH.

WEDNESDAY: Mostly cloudy. Chance of showers. Highs 60-67. Wind NW 5-15 MPH.

DAYS 6-10 (JUNE 8-12)

The same upper low brings another shower threat for June 8 before we get a break and a few dry and milder days June 9-11 before the next trough arrives from the northwest with a renewed shower chance to end the period.

DAYS 11-15 (JUNE 13-17)

Another upper low will dominate the weather for at least a portion of this period with additional unsettled weather at times and below normal temperatures.

DAYS 1-5 (JUNE 2-6)

One more summery day today before it’s back to New England springtime! While yesterday’s summertime feel was with 100% sun (except the early clouds to the south), today’s will feature more a cloud/sun mix, with the clouds eventually growing to produce isolated to scattered showers and thunderstorms this afternoon, and then as a strong back door cold front sweeps across the region this evening, a more general area of showers will occur. This will signal a significant temperature drop setting up a much cooler weekend. A northeasterly air flow will keep clouds around much of the time, but enough dry air works in for breaks of sun to develop midday and afternoon Saturday, and off and on on Sunday as well. While this is occurring, a low pressure area evolving offshore will stay far enough away to keep its rainfall mainly offshore – the exception being Cape Cod where some showers likely occur on Sunday. So other than some patchy drizzle near the eastern coastal areas with the northeast wind, expect a mainly dry weekend for much of the region despite the cloudiness and cool weather. Offshore low pressure may edge close enough for bands of showers in more of the region Monday before it feels the influence of a newly formed upper low a little further west, which will keep us unsettled with a shower chance on Tuesday as well, along with continued below normal temperatures.

TODAY: Sun/cloud mix. Isolated to scattered showers/thunderstorms mid afternoon on. Highs ranging from 70-77 Islands / Cape Cod to 84-91 away from shorelines, warmest in valleys. Wind W up to 10 MPH, coastal sea breezes. Briefly gusty and stronger wind can occur near any showers and storms.

TONIGHT: Mostly cloudy. Showers likely evening to the north of I-90 and mostly overnight from I-90 belt south. Areas of drizzle and light fog overnight especially eastern coastal locations. Lows 48-55. Wind W up to 10 MPH shifting to NE and increasing to 10-20 MPH from northeast to southwest beginning late evening.

SATURDAY: Mostly cloudy to partly sunny. Passing showers north to south early morning. Chance of drizzle early morning eastern coastal locations. Highs 56-63, coolest eastern coastal areas. Wind NE 5-15 MPH, higher gusts.

SATURDAY NIGHT: Variably cloudy. Lows 45-52. Wind NE 5-15 MPH.

SUNDAY: Partly to mostly cloudy. Possible showers Cape Cod. Highs 57-64, coolest eastern coastal areas. Wind NE-N 5-15 MPH with higher gusts.

SUNDAY NIGHT: Mostly cloudy. Showers possible mainly NH Seacoast and eastern MA. Lows 47-54. Wind N 5-15 MPH.

MONDAY: Mostly cloudy. Passing showers possible. Highs 58-65. Wind N 5-15 MPH.

MONDAY NIGHT: Mostly cloudy. Chance of showers in the evening. Lows 50-57. Wind N 5-15 MPH.

TUESDAY: Variably cloudy. Chance of showers. Highs 58-65. Wind N 5-15 MPH.

DAYS 6-10 (JUNE 7-11)

Upper level low pressure dominates the pattern with a northerly air flow becoming more westerly with time. Opportunities for showers at times, but dry more often. Temperatures below normal.

DAYS 11-15 (JUNE 12-16)

A broad upper level trough is expected to be in control with a few episodes of showers and possible thunderstorms. Temperatures below normal.

DAYS 1-5 (JUNE 1-5)

The story for the first couple days of June: summer teaser. But this will be like a cruel joke from mother nature. Why? The story of the weekend: Much cooler, limited sun, and while mainly dry there are a couple wet weather chances too. We start out with a friendly ridge of high pressure bringing us fair weather and above normal temperatures today into tomorrow. Later tomorrow ahead of an approaching back-door cold front a few showers and thunderstorms can pop up, and then the front crosses the region at night with a more widespread shower swath, a second that may come through early Saturday as the front settles south and some warm air is still riding up over the rather shallow cool air mass initially. I’m still optimistic that enough dry air works in for partial clearing during midday and afternoon Saturday. But with retrograding upper level low pressure moving into the region and surface low pressure organizing off the coast, we’ll get into an increasing northeast to north air flow through Sunday with more coolness, limited sun, and perhaps some drizzle and showers involved, especially in eastern locations of the WHW forecast area. With a a little luck we will have some intervals of drier air to break the clouds up at times Sunday as well. This looks a little more likely early in the week as the upper level low is over us and the surface low is to the east with a cooler northerly air flow and just the chance of a few passing showers Monday.

TODAY: Early-day low clouds MA South Coast / Cape Cod with patchy fog elsewhere, otherwise sunshine with some additional high altitude smoke. Highs 84-91 except cooler South Coast. Wind SW 5-15 MPH.

TONIGHT: Mostly clear. Lows 55-62. Wind SW up to 10 MPH.

FRIDAY: Sunny start, then a sun/cloud mix. Isolated afternoon showers and thunderstorms. Highs 84-91, cooler Cape Cod and a few other coastal locations. Wind W up to 10 MPH can still yield to local coastal sea breezes.

FRIDAY NIGHT: Mostly cloudy. Showers likely evening to the north of I-90 and mostly overnight from I-90 belt south. Areas of drizzle and light fog overnight especially eastern coastal locations. Lows 48-55. Wind W up to 10 MPH shifting to NE and increasing to 10-20 MPH from northeast to southwest beginning late evening.

SATURDAY: Mostly cloudy to partly sunny. Passing showers north to south morning. Chance of drizzle early morning eastern coastal locations. Highs 56-63, coolest eastern coastal areas. Wind NE 5-15 MPH, higher gusts.

SATURDAY NIGHT: Partly cloudy early then cloudy with showers/drizzle overnight. Areas of fog especially coast. Lows 45-52. Wind NE 5-15 MPH.

SUNDAY: Mostly cloudy with breaks of sun possible. Showers most likely early in the day but isolated showers still possible later. Highs 58-65, coolest eastern coastal areas. Wind NE-N 5-15 MPH, higher gusts.

SUNDAY NIGHT: Variably cloudy. Lows 45-52. Wind N 5-15 MPH.

MONDAY: Variably cloudy. Passing showers possible. Highs 58-65. Wind N 5-15 MPH.
