DAYS 1-5 (MARCH 29 – APRIL 2)

Classic early spring weather. This is what we’ll be dealing with in the days ahead. Now, to clear up a common and still-growing misconception, fueled largely be social media and nearly equally by mainstream media (non-meteorologists), when we pass the vernal equinox and spring official begins, that doesn’t just suddenly mean our days are filled with warm sunshine, blooming flowers, singing birds, etc. Spring is a transition between winter and summer, and it’s a long process, and the part of the process is often marked with frequent chilly spells and unsettled weather – a volatile pattern. We’ll see that process in progress these 5 days (and beyond, as you’ll see). Today, we lose the winterish chill of yesterday but seeing a high temp a half dozen to a dozen degrees milder than what occurred yesterday, but a late March chill will still dominate as a southwest wind increases as high pressure moves offshore. This increase in wind along with dry weather also elevates brush fire danger across the region today as well – marking the beginning of our “fire season”, which is peaked, in general, in the time after snow melt and before leaf-out of vegetation, and highest on dry, breezy/windy days. Today will be one of those days. Our warm-up continues as we enter the final 2 days of the month, but a frontal boundary to our northwest will edge closer by Tuesday, bringing the chance of rain showers to our region by then after dry weather Monday. The next forecast question to answer is the magnitude of warmth on Wednesday, dictated by the timing of a cold front moving our way trailing low pressure moving out of the Great Lakes into southeastern Canada, and the amount of cloudiness and the rain shower chance associated with it. Quicker timing and more clouds limit how warm we can get, while a slower front and less cloud cover would be conducive to a warmer outcome. I am leaning toward the former over the latter at this point, but keep in mind that just a subtle change can have me leaning in the other direction. Regardless, the front does pass through by Wednesday night, and we’ll find ourselves in a much cooler air mass by Thursday, with cloud cover dominant. Precipitation will be dependent on a few things: 1) A weak low pressure wave that may form on the front just to our south and pass by early in the day. 2) Low level moisture from the ocean as we have a northeasterly air flow driven by high pressure in eastern Canada. 3) The approach of another low pressure wave from the west later – if timing is quick enough. My leaning for this day is for 1 and 3 to be less influence and 2 to be more so, so just a cloudy day with some drizzle possible. This will be another day to monitor for detail and fine-tune as we get closer to it.

TODAY: Sun and patchy clouds. Highs 43-50. Wind SW 5-15 MPH.

TONIGHT: Mostly cloudy. Lows 35-42 evening, but may rise slightly overnight. Wind SW 5-15 MPH.

MONDAY: Partly sunny. Highs 48-55 South Coast, 56-63 elsewhere. Wind SW 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Lows 40-47. Wind SW 5-15 MPH.

TUESDAY: Variably cloudy. Chance of rain showers. Highs 60-67 except cooler South Coast, and may end up cooler in southern NH / northern MA. Wind SW 5-15 MPH, may shift to N or NE in southern NH / northern MA.

TUESDAY NIGHT: Variably cloudy. Lows 45-52 early, then rises overnight. Wind variable to SW 5-15 MPH.

WEDNESDAY: Variably cloudy. Midday and afternoon rain showers possible. Highs 52-59 South Coast, 59-66 just inland from South Coast through MA South Shore, 66-73 elsewhere. Wind SW 10-20 MPH.

WEDNESDAY NIGHT: Cloudy. Rain showers evening, ending overnight. Lows 35-42. Wind shifting to N 5-15 MPH.

THURSDAY: Cloudy. Chance of drizzle. Highs 42-49. Wind NE 5-15 MPH.

DAYS 6-10 (APRIL 3-7)

The weather in this stretch is again very much determined by the position of a frontal boundary and disturbances moving along it. I’m leaning toward chilly and somewhat unsettled through mid period, but there is a possibility of a brief spike of warmth around April 5 (Easter Sunday for those celebrating). There is a lot of detail to be worked out for this stretch of time.

DAYS 11-15 (APRIL 8-12)

Still expecting a continuation of the battle-zone pattern through this period as well with some unsettled episodes and temperature swings.

DAYS 1-5 (MARCH 28- APRIL 1)

As we head down the home stretch of March and arrive at April, we’ll start the 5-day period with a day a little reminiscent of mid winter, with varying amounts of clouds, perhaps a snow flurry, and well-below normal high temps in the 30s with a gusty breeze often making it feel more like the 20s. The difference between then and now is the sun angle, and that always takes the edge off the chill, if you’re fortunate enough to be in it while outside, also assuming it’s not hidden by the varying cloud cover that’s expected. Summary: If you have to be outside today, you may want a heavier jacket and a hat (and maybe gloves)! As we head to Sunday, we lose much of the wind, gain about a half dozen to a dozen degrees back on the temperature, and have more sunshine, but eventually mixed with high to mid level clouds – an indicator of warmer air returning aloft. This marks the transition to a few days of warmer weather ahead. The final two days of March and the first day of April all have the strong potential to produce above normal temperatures, but I do caution that a couple waves of low pressure passing to our north and high pressure in eastern Canada can send a frontal boundary southward far enough to thwart that warm-up for several hours at some point on Tuesday. This boundary can also bring heavier clouds and the chance of a few rain showers along with it. While it’s day 5 and lower confidence, I do see some signs that the boundary gets whisked back to the north as a more formidable low travels through the Great Lakes on Wednesday. That could push a warmer surge back through our region, and likely will, but even with that, the stronger southwesterly wind that would accompany it would end up being a cooling breeze for the South Coast and Cape Cod, which is typical for this time of year. Depending on the time of the low’s trailing and approaching cold front, we may end up seeing another shower threat by Wednesday’s end.

TODAY: Variably cloudy. A possible snow flurry. Highs 36-43. Wind NW 10-20 MPH, higher gusts.

TONIGHT: Clearing. Lows 22-29. Wind NW to W 5-15 MPH.

SUNDAY: Sunshine gives way to clouds. Highs 43-50. Wind W 5-15 MPH.

SUNDAY NIGHT: Mostly cloudy. Lows 35-42 evening, but may rise slightly overnight. Wind SW 5-15 MPH.

MONDAY: Partly sunny. Highs 48-55 South Coast, 56-63 elsewhere. Wind SW 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Lows 40-47. Wind SW 5-15 MPH.

TUESDAY: Variably cloudy. Chance of a rain shower southern NH / northern MA. Highs 60-67 except cooler South Coast, and may end up cooler in southern NH / northern MA. Wind SW 5-15 MPH, may shift to N or NE in southern NH / northern MA.

TUESDAY NIGHT: Variably cloudy. Lows 45-52 early, then rises overnight. Wind variable to SW 5-15 MPH.

WEDNESDAY: Variably cloudy. Late-day or nighttime rain showers possible. Highs 52-59 South Coast, 60-67 just inland from South Coast through MA South Shore, 67-74 elsewhere. Wind SW 10-20 MPH.

DAYS 6-10 (APRIL 2-6)

A couple of brief warmer spikes can occur during a time I expect our region to be on the colder side of a boundary. The greatest chance of unsettled weather is April 3 and later April 5 or 6, the first with a low pressure wave moving along the boundary, the second with a frontal system from the west.

DAYS 11-15 (APRIL 7-11)

Still expecting a continuation of the battle-zone pattern through this period as well with some unsettled episodes and temperature swings.

DAYS 1-5 (MARCH 27-31)

A cold front has passed through most of the region and is moving offshore early this morning, taking the nighttime’s rainfall with it. Today will be a day of declining temperature and lingering cloudiness, with an eventual clearing trend developing. Colder air will continue to filter into the region and tonight / Saturday will be quite chilly for late March. We may see a few snow showers around on Saturday, especially first thing in the morning to the south and late in the day from west to east, in response to upper level low pressure crossing the region. While Sunday is a cool day, it does recover a little and we lose most of the wind we have Saturday, but clouds will make a come-back as warmer air starts arriving from the south and west. A warm front will cross the region at some point Monday, followed by a cold front by early Tuesday, parented by low pressure passing to our north. This will continue the variable temperature pattern, which is currently dominated by the cooler side of normal, and that is how will we wrap up the month of March early next week.

TODAY: Any early rain ends South Coast, clouds linger and gradually give way to more sun west to east. Highs 48-55 early, then falling through the 40s. Wind NW 5-15 MPH, gusts around 20 MPH.

TONIGHT: Partly cloudy. Lows 26-33. Wind NW 5-15 MPH, gusts around 20 MPH.

SATURDAY: Lots of clouds / intervals of sun. A possible snow flurry. Highs 36-43. Wind NW 10-20 MPH, higher gusts.

SATURDAY NIGHT: Clearing. Lows 22-29. Wind NW to W 5-15 MPH.

SUNDAY: Sunshine gives way to clouds. Highs 43-50. Wind W 5-15 MPH.

SUNDAY NIGHT: Mostly cloudy. Lows 35-42 evening, but may rise slightly overnight. Wind SW 5-15 MPH.

MONDAY: Variably cloudy. A rain shower possible. Highs 52-59, cooler South Coast. Wind SW 5-15 MPH.

MONDAY NIGHT: Mostly cloudy. Rain showers possible. Lows 42-49. Wind SW 5-15 MPH shifting to N.

TUESDAY: Mostly cloudy. A rain shower possible. Temperatures steady in the 40s. Wind N to NE 5-15 MPH.

DAYS 6-10 (APRIL 1-5)

A couple of brief warmer spikes can occur during a time I expect our region to be on the colder side of a boundary. The greatest chance of unsettled weather is April 3 and later April 4 or 5, the first with a low pressure wave moving along the boundary, the second with a frontal system from the west. Timing and details remain uncertain.

DAYS 11-15 (APRIL 6-10)

Still expecting a continuation of the battle-zone pattern through this period as well with some unsettled episodes and temperature swings, typical of a New England spring.

DAYS 1-5 (MARCH 26-30)

A warm front goes by the region this morning and rain comes to an end. While lots of clouds linger today, we’ll see intervals of sun and a nice push of mild air making it feel more like late April or May. However, a southwesterly wind, as you know, is a cooling ocean breeze if you’re along the South Coast and into southeastern MA, so the air there will not be quite as warm as it is off to the north and west. Tonight, a strong cold front ambles its way southeastward across our region, bringing a band of rainfall. During Friday, this front moves offshore and we have a shifted wind, a drying trend, stubborn cloudiness at first then then gives way to some sun, and a high temperature early in the day followed by a decline. Our weekend will feature below normal temperatures with a colder Canadian air mass in place. Saturday’s weather will feature a lot of clouds, intervals of sun, a gusty wind, and maybe even a few snow flurries as a pool of very cold air aloft crosses the region. Sunday will be dry with less wind and more sun initially, but clouds increase again from the west as milder air begins to move back in this direction, at first aloft, triggering the increase in high and mid level cloudiness. Monday’s weather depends on the ability of a warm front to get through the region fully. I’m leaning milder with varying amounts of cloudiness at this time.

TODAY: Cloudy start with rain ending west to east. Partial sun midday on then mainly cloudy by evening. Highs 60-67 except 53-60 South Coast to MA South Shore except 46-53 Cape Cod / Islands. Wind SW increasing to 10-20 MPH, gusts to 30 MPH.

TONIGHT: Cloudy. Rain showers arrive. Lows 45-52. Wind SW 5-15 MPH, gusts 20-25 MPH.

FRIDAY: Cloudy with periodic rain showers in the morning, tapering off midday. Mostly cloudy to partly sunny afternoon with greatest chance for more sun northwest of Boston. Highs 48-55 early, then falling through the 40s. Wind NW 5-15 MPH, gusts around 20 MPH.

FRIDAY NIGHT: Variably cloudy. A brief snow shower possible. Lows 26-33. Wind NW 5-15 MPH, gusts around 20 MPH.

SATURDAY: Lots of clouds / intervals of sun. A possible snow flurry. Highs 36-43. Wind NW 10-20 MPH, higher gusts.

SATURDAY NIGHT: Clearing. Lows 22-29. Wind NW to W 5-15 MPH.

SUNDAY: Sunshine gives way to more clouds. Highs 43-50. Wind W 5-15 MPH.

SUNDAY NIGHT: Mostly cloudy. Lows 35-42 evening, but may rise slightly overnight. Wind SW 5-15 MPH.

MONDAY: Variably cloudy. A rain shower possible. Highs 52-59, cooler South Coast. Wind SW 5-15 MPH.

DAYS 6-10 (MARCH 31 – APRIL 4)

Front in vicinity with a rain shower chance for the final day of March and first day of April. Temperature may start mild then turn colder. Leaning chilly and unsettled April 2-4 with high pressure in eastern Canada and a boundary between cold air and mild air sitting just to our south with at least one low pressure wave moving along it. A lot of detail to work out for this time period but the initial idea is below normal temperatures, not much sun, and some precipitation probable.

DAYS 11-15 (APRIL 5-9)

The “battle-zone” pattern is likely to still be ongoing. Hard to say which side of it we end up on, but likely a combo of both resulting in some notable swings in temperature and some unsettled weather as well.

DAYS 1-5 (MARCH 25-29)

No coating of snow this morning! Just dry, chilly weather. But a warm-up commences today, albeit short-lived. High pressure over the region slides offshore and a warm front approaches from the west later on. This front will generate one area of high clouds that will filter the sun for a while this morning into midday, and then another area of clouds races in to dim or blot out the sun entirely before it sets tonight. Other than brief light rain possible in southern NH and northern MA from the passing warm front this evening / tonight, it will be dry. Warmer air surges into the region Thursday on a gusty southwesterly wind behind that warm front and ahead of a slow-moving but sharp cold front. This front will have more moisture to work with, bringing us periods of rain showers Thursday night into Friday, which will eventually taper off, but clouds will likely remain stubborn on Friday due to the slow movement of the front and a little wave of low pressure forming on it and passing to our south later in the day. There may be just enough moisture available for this passing wave to squeeze out a brief episode of light rain, mix, or wet snow Friday evening, before it starts to strengthen into a stronger low as it moves away. This drags colder air into the region for this coming weekend, which will be dry. Saturday will be the colder and windier of the two days with a sun / cloud mix, while Sunday features more sun and less wind.

TODAY: Sun, brightest early, filtered for a while mid morning to midday, briefly brighter, then fading later. Highs 50-57 except 45-52 South Coast. Wind W to SW up to 10 MPH.

TONIGHT: Mostly cloudy. Brief light rain possible southern NH / northern MA. Lows 36-43. Wind S up to 10 MPH.

THURSDAY: More clouds than sun. Highs 50-57 South Coast, 58-65 elsewhere. Wind SW 10-20 MPH, gusts 25-30 MPH.

THURSDAY NIGHT: Cloudy. Rain showers arrive. Lows 45-52. Wind SW 5-15 MPH, gusts 20-25 MPH.

FRIDAY: Cloudy with periodic rain showers in the morning, tapering off midday. Mostly cloudy afternoon. Highs 48-55 early, then falling through the 40s. Wind NW 5-15 MPH, gusts around 20 MPH.

FRIDAY NIGHT: Variably cloudy with brief light rain / mix / snow possible evening. Lows 26-33. Wind NW 5-15 MPH, gusts around 20 MPH.

SATURDAY: Sun & passing clouds. Highs 36-43. Wind NW 10-20 MPH, higher gusts.

SATURDAY NIGHT: Clearing. Lows 22-29. Wind NW to W 5-15 MPH.

SUNDAY: Sunshine and some high clouds. Highs 42-49. Wind W 5-15 MPH.

DAYS 6-10 (MARCH 30 – APRIL 3)

March 30-31 features a wave of low pressure traveling eastward and passing north of our region so that we get a warm front / cold front combo. Limited moisture for this system means only briefly unsettled weather is possible with otherwise just varying amounts of cloudiness. A quick warm-up March 30 is likely followed by a quick chill-down March 31. The first few days of April are a lower confidence forecast but heading toward a potential unsettled stretch with Canadian high pressure to our north, warmer air to our south, and a frontal boundary nearby, separating those air masses, with our region more likely on the colder side of it. Keep in touch for updates on the evolution of the more specific weather for these days.

DAYS 11-15 (APRIL 4-8)

The “battle-zone” pattern is likely to still be ongoing. Hard to say which side of it we end up on, but likely a combo of both resulting in some notable swings in temperature and some unsettled weather as well – not every day, but too early to pinpoint any specifics.

DAYS 1-5 (MARCH 24-28)

Again some folks wake up to a fresh coating of snow that fell from passing snow showers last night. This was in response to upper level low pressure moving through the region, which now lingers as a band of clouds over southeastern NH and eastern MA with just a few fleeting flakes from southern Plymouth County to Cape Cod as of sunrise. Any snow that fell will vanish as the clouds break and the sun rises higher into the sky, and high pressure building in gives us dry weather for the balance of the day today, a dry and chilly night, and fair weather with slightly milder air moving in for Wednesday. The high will slip offshore later Wednesday and a weak cold front approaches from the west. It never quite makes it all the way through, and is moisture-starved anyway, so all we’ll see it from it are some clouds anyway. The boundary actually heads back to the north Thursday in response to approaching low pressure from the west. This system will come through our region with some wet weather late Thursday to early Friday, behind which a gusty wind will develop and a transition back to colder air, especially Friday night and Saturday, but with dry weather also returning.

TODAY: Considerable cloudiness early in eastern coastal areas including lingering snow flurries in southeastern MA, otherwise sunshine and passing clouds. Highs 38-45. Wind NW to N 5-15 MPH.

TONIGHT: Partly cloudy to mostly clear. Lows 28-35. Wind variable under 10 MPH.

WEDNESDAY: Sun dominant in the morning before clouds increase from west to east in the afternoon. Highs 46-53, coolest Cape Cod. Wind W to SW 5-15 MPH.

WEDNESDAY NIGHT: Variably cloudy. Lows 35-42. Wind W 5-15 MPH.

THURSDAY: Partly to mostly cloudy. Highs 50-57. Wind S 5-15 MPH.

THURSDAY NIGHT: Cloudy. Rain arrives. Lows 35-42. Wind SW 5-15 MPH.

FRIDAY: Cloudy early with rain ending, then slow clearing. Highs 45-52. Wind N 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Lows 22-30. Wind NW 10-20 MPH, higher gusts. Wind chill below 20.

SATURDAY: Sun & passing clouds. Highs 36-43. Wind NW 10-20 MPH, higher gusts.

DAYS 6-10 (MARCH 29 – APRIL 2)

Up and down temps, averaging near to below normal, and a couple periods of unsettled weather possible, but likely from quick-passing systems.

DAYS 11-15 (APRIL 3-7)

Battle zone set-up (warm to south, colder to north). A couple of unsettled weather bouts end up likely, and leaning toward the colder air being more dominant, but brief warmer surges are certainly possible.

DAYS 1-5 (MARCH 23-27)

A wave of low pressure moving by just to our south this morning is responsible for the shield of precipitation over much of the region, mainly rain but mixed with (and turning to) wet snow on its northern edge, which progresses south and east as the morning goes along until it moves offshore. At worst, a slushy coating of snow can occur in unpaved surfaces from this portion of the two-part event today. The second part of it will be scattered to clustered snow showers later this afternoon into this evening from upper level low pressure moving across the region. These can be responsible for a coating of snow in some areas, again mainly on unpaved surfaces, and will only be around for a few hours. Overnight and Tuesday, high pressure builds in with a fair weather and a late March chill in the air. The next low pressure system is a weak one and will pass north of our region late Wednesday to early Thursday. Its weak trough and frontal system may bring a passing rain shower to the region late Wednesday. A follow up system, slightly stronger and with more moisture, will move across the region late Thursday to early Friday with a quick warm front / cold front combo bringing some rain to the region which can end as a mix with sleet and / or wet snow early Friday before that system exits to our east.

TODAY: Cloudy. Rain turns to wet snow (some sleet mixed in) with a slushy coating on some unpaved surfaces before tapering off northwest to southeast. Afternoon snow showers redevelop, may be mixed with rain initially South Coast. Highs 37-44. Wind N 5-15 MPH, higher gusts.

TONIGHT: Mostly cloudy early with snow showers tapering off – additional slushy coatings possible early. Clearing overnight. Lows 22-29. Wind N 5-15 MPH.

TUESDAY: Mostly sunny to partly cloudy. Highs 38-45. Wind NW 5-15 MPH.

TUESDAY NIGHT: Partly cloudy to mostly clear. Lows 28-35. Wind variable under 10 MPH.

WEDNESDAY: Increasing clouds. Highs 46-53, coolest Cape Cod. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy with rain showers evening. Partly cloudy overnight. Lows 35-42. Wind W 5-15 MPH.

THURSDAY: Partly to mostly cloudy. Highs 50-57. Wind S 5-15 MPH.

THURSDAY NIGHT: Cloudy. Rain arrives. Lows 35-42. Wind SW 5-15 MPH.

FRIDAY: Cloudy early with rain ending possibly mixed with wet snow, then slow clearing. Highs 45-52. Wind N 5-15 MPH.

DAYS 6-10 (MARCH 28 – APRIL 1)

Up and down temps, averaging near to below normal, and a couple periods of unsettled weather possible, but likely from quick-passing systems.

DAYS 11-15 (APRIL 2-6)

Trend is for up and down temps and a couple unsettled weather chances – typical of early spring. Many details TBD.

DAYS 1-5 (MARCH 22-26)

A low pressure wave will move across our region today through early Monday including an upper level low pressure area that will take until Monday night to pass through the region. This produces an extended period of unsettled weather. Some light snow / mix has already occurred, especially in northern MA and southern NH during the overnight / early morning, but this has had virtually no impact and is generally gone, leaving us just overcast early this morning. More moisture arrives during midday and afternoon and with a just-warm-enough atmospheric profile, the resultant precipitation will be mainly in the form of rain, though a little wet snow / sleet mixed in cannot be ruled out, especially north of Route 2. The trend will be for this area to move to the south as we get into tonight and Monday morning, but it will take its time, and another little low pressure wave moving the frontal boundary as it sinks southward, combined with incoming colder air, will produce some wet snow and sleet especially north of I-90 while it’s still mainly rain, maybe mixed with wet snowflakes or ice pellets before it all tapers off during the day. This area of frozen precipitation can produce a slushy coating mainly on unpaved surfaces Monday morning but should have no noticeable impact on driving. It’s scattered snow showers from the upper low in the afternoon and evening that can become heavy enough to produce a coating to 1 inch accumulation – not widespread, but in scattered locations. This can have brief impact on driving / walking on untreated surfaces, especially as darkness falls. Keep that in mind if you have late Monday travel plans. High pressure builds in with fair weather for Tuesday. The next system still looks destined to have its low pressure center travel to our north late Wednesday with a quick warm-front / cold-front combo producing a short period of unsettled weather. Brief clearing Thursday is overtaken by clouds as the next low pressure system approaches from the west later on.

TODAY: Cloudy. Any early spotty snow / sleet ends in southern NH then rain arrives west to east midday on, may be mixed with wet snow and sleet at times northern MA and southern NH. Highs 38-45 except 45-52 south of I-90. Wind variable to N 5-15 MPH.

TONIGHT: Cloudy. Periods of rain, some wet snow / sleet possible, favoring areas south of Route 2. Lows 32-39. Wind N to NE 5-15 MPH.

MONDAY: Mostly cloudy. Rain / sleet / snow possible especially Route 2 corridor southward first half of the day. Scattered snow showers favoring areas north of I-90 mid to late afternoon into evening with scattered accumulation of mainly under 1 inch. Highs 38-45. Wind N 10-20 MPH, higher gusts in the afternoon.

MONDAY NIGHT: Clearing. Lows 22-29. Wind N 5-15 MPH,.

TUESDAY: Sunny to partly cloudy. Highs 38-45. Wind NW 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Lows 28-35. Wind variable under 10 MPH.

WEDNESDAY: Increasing clouds. Highs 48-55, cooler Cape Cod. Wind SW 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy with rain showers evening. Partly cloudy overnight. Lows 35-42. Wind NW 5-15 MPH.

THURSDAY: Partly to mostly cloudy. Chance of mix / rain showers at night. Highs 47-54. Wind SW 5-15 MPH.

DAYS 6-10 (MARCH 27-31)

Unsettled weather chances early March 27 and again March 29. Some up and down temperatures but overall averaging somewhat below normal.

DAYS 11-15 (APRIL 1-5)

Trend is for up and down temps and a couple unsettled weather chances – typical of early spring. Many details TBD.

DAYS 1-5 (MARCH 21-25)

One system departs this morning with lingering clouds which eventually give way to a sun / cloud mix and a gusty breeze behind offshore low pressure. The next system quick on its heels will approach tonight, and this will be a low pressure wave that dives southeastward across the region during Sunday. Clouds advance tonight, and we can see some light snow / sleet mainly north of I-90, especially north of Route 2 where some light accumulation can occur. To the south, spotty mixed rain, sleet, and wet snow can occur. The frontal boundary associated with the wave slips to the south during Sunday where the focus will be for more widespread precipitation but mostly in the form of rain. It is during Sunday night and part of Monday when we need to watch for a low pressure wave that can spread a shield of snow / mix into the region again, but this may again favor areas to the south. Otherwise it will be generally cloudy, chilly, and raw through Monday. High pressure builds in with briefly nicer weather for Tuesday, though it will be on the cool side with a breeze. The next low pressure system looks like it will take a track to our north Wednesday with slightly milder weather and a chance of rain showers.

TODAY: Mostly cloudy to partly sunny. Highs 43-50. Wind NW 5-15 MPH, higher gusts.

TONIGHT: Partly cloudy, then becoming cloudy. Chance of some snow / sleet mainly north of Route 2 with spotty mix / rain to the south overnight. Lows 32-39. Wind variable 5-15 MPH.

SUNDAY: Cloudy. Early spotty snow / sleet possible southern NH and northern MA. Periodic rain and some possible mix mainly I-90 belt southward otherwise. Highs 38-45 except 45-52 south of I-90. Wind variable to N 5-15 MPH.

SUNDAY NIGHT: Cloudy. Periods of rain, some wet snow / sleet possible, favoring areas south of I-90. Lows 32-39. Wind N to NE 5-15 MPH.

MONDAY: Mostly cloudy. Rain / sleet / snow possible especially I-90 belt southward first half of the day. Highs 38-45. Wind N 10-20 MPH.

MONDAY NIGHT: Clearing. Lows 22-29. Wind N 5-15 MPH,.

TUESDAY: Sunny to partly cloudy. Highs 38-45. Wind NW 5-15 MPH.

TUESDAY NIGHT: Increasing clouds. Lows 28-35. Wind variable under 10 MPH.

WEDNESDAY: Variably cloudy. Chance of rain showers. Highs 50-57, cooler South Coast. Wind SW 5-15 MPH.

DAYS 6-10 (MARCH 26-30)

Unsettled weather chances March 27 and 29. Some up and down temperatures but overall averaging somewhat below normal.

DAYS 11-15 (MARCH 31 – APRIL 4)

Overall pattern looks mostly dry and on the cooler side of normal with one brief interruption from a passing disturbance or storm system, favoring early to mid period.

DAYS 1-5 (MARCH 20-24)

We will say goodbye to winter and hello to spring in the astronomical sense today at 10:46 a.m. EDT, but we are not necessarily done seeing winter-like weather in the days ahead, as our overall pattern is chilly and still active with several weather systems to pass through the region. The first one will not have any frozen precipitation with it for our region as it passes through later today and this evening, with mild enough air that we just see a period of rain along the front parented by low pressure passing to our north. High pressure builds in for a nice day Saturday. The next low pressure system tracks across our region on Sunday, and its a bit of a race between a frontal boundary and the onset of precipitation to determine of any snow / sleet can be involved. Eventually this should be mostly rain for the region Sunday afternoon into evening, but as colder air is reinforced as the system starts to pull away, enough moisture can linger for some sleet and snow to become involved again at least in portions of the region before it tapers off during Monday. There are still some details to work out regarding this complex set-up. Current timing suggest high pressure builds back in with fair weather as a result for Tuesday.

TODAY: Sun followed by clouds. Late day rain arrives west to east. Highs 45-52. Wind SW 5-15 MPH.

TONIGHT: Cloudy with evening rain. Breaking clouds and patchy fog overnight. Lows 38-45. Wind SW to W up to 10 MPH.

SATURDAY: Sun / cloud mix. Highs 48-55. Wind W 5-15 MPH.

SATURDAY NIGHT: Partly to mostly cloudy. Lows 40-47. Wind SW 5-15 MPH.

SUNDAY: Cloudy. Chance of rain, mainly midday and afternoon and favoring northern areas first, southern areas later, may start as snow / sleet in some areas mostly north of I-90. Highs 45-52 north of I-90 and on the South Coast with 52-59 in between these areas. Wind variable to N 5-15 MPH.

SUNDAY NIGHT: Cloudy. Periods of rain, some wet snow / sleet possible. Lows 32-39. Wind N to NE 5-15 MPH.

DAYS 6-10 (MARCH 25-29)

Unsettled weather chances March 25, 27, 29, any of which can include some frozen precipitation as temperatures run below normal.

DAYS 11-15 (MARCH 30 – APRIL 3)

Overall pattern looks mostly dry and on the cooler side of normal with one brief interruption from a passing disturbance or storm system, favoring mid period.

DAYS 1-5 (MARCH 19-23)

The weather pattern remains active, which is typical as we transition from winter to spring. In fact we mark the “official” transition with the occurrence of the vernal equinox Friday morning at 10:46 a.m. EDT. Before we get to that, we’ll see a sun / cloud mix today as high pressure slides offshore and we experience a slight temperature moderation off yesterday’s late winter refrigerator chill. A weak low pressure area will pass north of our region tonight and may produce a brief light snow shower mainly north of I-90, but any that do occur will have no impact as they occur with limited available moisture and last a very short time. Friday’s weather will feel a tiny bit more like the season that’s incoming as we warm up a little bit more, but sunshine will give way to clouds as the next in a series of disturbances approaches – this one another low heading for a path north of our region, sending a frontal system through late day and evening. Milder air and more available moisture means that much of the region will see a period of rain, but not too heavy. This exits our region overnight and sets up a fair weather day Saturday with a sun / cloud mix and temperatures fairly typical of late March. Sunday, the next frontal boundary comes our way as the next in a series of lows passing to our north does so. Timing is a little in question on this, but at some point we are likely to see wet weather move in. It may wait until midday or afternoon to do so. Details to be worked out. It looks like a milder day, at least initially. Once the front goes by, however, we see another temperature drop. This may not occur until sometime late Sunday or Sunday night, again depending on frontal timing. Monday looks like a breezy, chilly early spring day as some areas may see a few snow flurries with an upper low moving across the region behind the recently-passed frontal boundary.

TODAY: Partly sunny. Highs 42-49. Wind S 5-15 MPH.

TONIGHT: Variably cloudy. A brief snow flurry possible mainly southern NH / northern MA. Lows 32-39. Wind S up to 10 MPH.

DAYS 11-15 (MARCH 29 – APRIL 2)

Overall pattern looks mostly dry and on the cooler side of normal with one brief interruption from a passing disturbance or storm system, favoring mid to late period.

DAYS 1-5 (MARCH 18-22)

High pressure brings dry weather but below normal temperatures today, though wind will be much lighter than yesterday as the high center moves overhead. The high will slip off to the east Thursday with continued fair weather but a few more clouds and a temperature moderation. A weak low pressure system will pass to our north Thursday night and early Friday, its weak cold front coming through early Friday with maybe a brief shower of light rain or snow. Another system approaches later Friday and passes by that night into early Saturday. Milder air in place at that time means any precipitation will likely all as rain, but this will be a minor impact system. A cold front will cross the region Saturday night into Sunday with another rain shower chance, introducing more wind and a shot of colder air for on Sunday.

TODAY: Mostly sunny. Highs 35-42. Wind W up to 10 MPH becoming variable.

TONIGHT: Partly cloudy. Lows 22-29. Wind variable to S up to 10 MPH.

Overall pattern looks mostly dry and on the cooler side of normal with one brief interruption from a passing disturbance or storm system, favoring later in the period.

DAYS 1-5 (MARCH 17-21)

From the NWS, there are flood warnings for minor flooding through today on the following rivers in MA and RI:

Sudbury River at Saxonville affecting Middlesex County.

Pawtuxet River at Cranston affecting Kent and Providence Counties.

Taunton River Near Bridgewater affecting Plymouth and Bristol
Counties.

Wood River at Hope Valley affecting Washington County.

The rain and strong wind gusts from the storm are behind us as the low pressure area responsible for it moves through eastern Canada as a large, strong storm system. This keeps us in its circulation today and we may see a sprinkle of rain this morning and a few snow flurries this afternoon as colder air moves in behind the storm. High pressure builds in tonight and Wednesday with fair, chilly, but more tranquil conditions. The high slides to the east Thursday, a day which will feature some sun, more clouds, and slightly milder air. A weak disturbance passing by on Friday morning may produce a few snow flurries for the final hours of winter, before the vernal equinox at 10:46 a.m. EDT marks the start of spring. The rest of Friday will feature dry weather but may carry quite a bit of cloudiness. Another disturbance moves our way via the Great Lakes on Saturday, and its warm front may produce some early-day rainfall, based on current expecting timing. The passage of the warm front would allow a milder afternoon that day.

TODAY: Lots of clouds early including the chance of a brief sprinkle of rain from west to east into mid morning, then a sun / cloud mix with a slight chance of a passing light snow shower from midday on. Temperatures decline from the 40s to the 30s. Wind W 15-25 MPH, gusts 30-40 MPH.

TONIGHT: Mostly clear. Lows 18-25. Wind W 5-15 MPH, higher gusts, diminishing overnight.

WEDNESDAY: Mostly sunny. Highs 36-43. Wind W up to 10 MPH becoming variable.

WEDNESDAY NIGHT: Partly cloudy. Lows 22-29. Wind variable to S up to 10 MPH.

THURSDAY: Partly sunny. Highs 42-49. Wind S 5-15 MPH.

THURSDAY NIGHT: Variably cloudy. Lows 33-40. Wind S 5-15 MPH.

FRIDAY: Mostly cloudy. A brief snow shower possible early. Highs 45-52. Wind SW 5-15 MPH.

FRIDAY NIGHT: Mostly cloudy. Lows 38-45. Wind S 5-15 MPH.

SATURDAY: Cloudy with a chance of rain early, then a sun / cloud mix. Highs 50-57. Wind SW 5-15 MPH.

DAYS 6-10 (MARCH 22-26)

A cold front moves through Sunday with lots of clouds, maybe some rain showers, and a falling temps. Watching one disturbance for potential precipitation later March 24 or March 25, otherwise a generally dry and chilly late March / early spring regime is expected for the balance of the period.

DAYS 11-15 (MARCH 27-31)

Watching an early to mid period precipitation potential in an otherwise mostly dry, chilly weather pattern to wrap up the month of March.

DAYS 1-5 (MARCH 16-20)

Intensifying low pressure tracks through the Great Lakes and across eastern Canada today and tonight. We’ll have a stormy Monday to start the week as a result. The storm’s warm front will move through our region early this morning with a batch of rain, some of it heavy, that will then taper to scattered rain showers later in the morning into this afternoon in the warm sector of the storm system, when we’ll see stronger, gusty southerly winds. A couple areas of widespread rain showers and possible embedded thunderstorms will cross the region from late this afternoon well into tonight prior to the storm’s cold front crossing the region from west to east, which will put an end to the rainfall in the pre-dawn hours, possibly just after Tuesday’s dawn on Cape Cod. As the storm continues into Atlantic Canada, our weather for St. Patrick’s Day will feature a gusty westerly wind, colder air, and generally dry weather, although a secondary cold front and some low level moisture from the Great Lakes can trigger a few snow showers during the day. The cold air delivered by this front will make Tuesday night feel a bit like mid winter, especially with windy conditions in the evening. High pressure builds in from the west on Wednesday, with fair and chilly weather but less wind. As this high slips eastward off the coast later in the week, we’ll see a temperature moderation but also more cloudiness at times, especially by Friday as a disturbance passes by to our northwest. This can trigger a couple rain showers in the area to mark the start of spring. The vernal equinox occurs at 10:46 a.m. EDT on Friday.

TODAY: Cloudy. Widespread rain showers until mid morning and returning again mid to late afternoon with just scattered rain showers between those times. Highs 57-64 except 50-57 South Coast. Wind SE 5-15 MPH early, then S 15-25 MPH with higher gusts.

TONIGHT: Mostly cloudy with widespread rain showers and embedded thunderstorms, ending from west to east overnight. Breaking clouds toward dawn from west to east. Lows 35-42. Wind S 15-25 MPH, gusts 35-55 MPH, with isolated gusts 55-65 MPH possible east of I-95, favoring southeastern MA and RI, shifting to W from west to east late evening and overnight, diminishing slightly.

TUESDAY: Sun and passing clouds. Chance of a snow shower. Highs 38-45. Wind W 10-20 MPH, gusts 25-35 MPH.

TUESDAY NIGHT: Mostly clear. Lows 18-25. Wind W 5-15 MPH, higher gusts, diminishing overnight.

WEDNESDAY: Mostly sunny. Highs 36-43. Wind W up to 10 MPH becoming variable.

WEDNESDAY NIGHT: Partly cloudy. Lows 22-29. Wind variable to S up to 10 MPH.

THURSDAY: Partly sunny. Highs 42-49. Wind S 5-15 MPH.

THURSDAY NIGHT: Variably cloudy. Lows 33-40. Wind S 5-15 MPH.

FRIDAY: Mostly cloudy. Chance of a rain shower. Highs 48-55. Wind SW 5-15 MPH.

DAYS 6-10 (MARCH 21-25)

March 21-22 weekend looks unsettled with a colder trend and a chance of some rain / mix / snow, but no major storminess indicated. Details TBD. Trend is for a drier, chilly pattern next week.

DAYS 11-15 (MARCH 26-30)

Precipitation threat early period then another surge of cold air follows with the overall pattern still chilly and on the drier side late month.

DAYS 1-5 (MARCH 15-19)

Low pressure will impact our weather over the next 3 days as it travels northeastward from the Midwest through the Great Lakes and across eastern Canada. The preliminary impact comes today in the form of cloudiness as a warm front crosses the region, but with not enough moisture to produce any precipitation. The main impact comes from pre-dawn Monday through late Monday evening as we get into a stronger southerly air flow with abundant subtropical moisture ahead of the storm’s cold front, providing a stronger, gusty wind and waves of rain showers, some of which can be on the heavier side. Isolated damaging wind gusts (and some resultant power outages) are possible. Rainfall combined with melting snowfall from the mountains coming down the streams and rivers can cause some flooding on those (which can persist into mid week, especially larger rivers). Thunderstorms can occur as the cold front sweeps eastward through the region, putting an end of the rain portion of the event later Monday night. Behind this system we’ll still feel its impact on Tuesday in the form of a gusty wind and colder weather, though it will be a dry St. Patrick’s Day. Chilly and dry weather is expected Wednesday as high pressure moves in. Some clouds return Thursday as milder air makes an attempt to return on the back side of high pressure and ahead of low pressure and a warm front moving out way from the Great Lakes.

TODAY: Limited sun / lots of clouds. Highs 42-49. Wind variable to SE up to 10 MPH.

TONIGHT: Cloudy. Rain showers arrive overnight and become widespread. Temperatures steady in 40s South Coast but rise to 50s elsewhere. Wind SE to S increasing to 10-20 MPH with higher gusts overnight.

MONDAY: Cloudy. Widespread rain showers until mid morning and returning again mid to late afternoon with just scattered rain showers between those times. Highs 57-64 except 50-57 South Coast. Wind S 15-25 MPH, gusts 30-50 MPH (possibly higher in some higher elevation and coastal areas).

MONDAY NIGHT: Mostly cloudy with widespread rain showers and embedded thunderstorms, ending from west to east overnight. Breaking clouds toward dawn from west to east. Lows 32-39. Wind S 15-25 MPH, gusts 35-55 MPH, strongest in higher elevations, shifting to W from west to east late evening and overnight, diminishing slightly.

TUESDAY: Sun and passing clouds. Highs 40-47. Wind W 10-20 MPH, gusts 25-35 MPH.

TUESDAY NIGHT: Mostly clear. Lows 27-34. Wind W 5-15 MPH, higher gusts.

WEDNESDAY: Mostly sunny. Highs 40-47. Wind W 5-15 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 22-29. Wind variable up to 10 MPH.

THURSDAY: Partly sunny. Highs 47-54. Wind S 5-15 MPH.

DAYS 6-10 (MARCH 20-24)

The Vernal Equinox occurs at 10:46 a.m. on Friday March 20, marking the beginning of spring. Unsettled weather is possible that day and into the weekend with a couple of disturbances / low pressure areas passing by, though major storminess is not indicated. This may wind up with a shot of cold air to end next weekend. We watch for the next storm system that may impact the region toward the end of the period.

DAYS 11-15 (MARCH 25-29)

Some up and down temps indicated for late month with another storm system potentially about mid period with a precipitation threat. A lot of detail to work out in this medium range forecast with uncertainty and seasonal volatility as factors.
