DAYS 1-5 (MARCH 24-28)

Unsettled chilly early spring weather will be the general theme this week. Today, low pressure in the Great Lakes with a frontal boundary extending into our area has spread clouds into the region (though a few of you may have caught a briefly colorful sunrise in eastern areas). A secondary low will form and move across our area by this evening. This system throws a disorganized slug of precipitation into our region this morning, with mainly rain but enough cold air in place for some snow in portions of our region mainly I-95 west and I-90 north, with some brief minor accumulation in highest elevations before rain takes over. The rain will end this evening as the new low pushes off to the northeast. Upper level low pressure crossing the region Tuesday will keep it cool and there can be a passing light rain shower, even some mix in higher elevations north and west of Boston. Following closely behind is another low pressure impact for Wednesday. This will be a small, fast-moving system mainly to impact the region during the first half to two thirds of the day, but it will be just cold enough so that if its precipitation shield is expansive enough, additional mix/snow can occur especially interior higher elevations. We’d also have to watch for any moderate intensity precipitation which could initiate mix/snow closer to the coast for a brief time too. In either case, this system won’t hang around and it’s not to be accompanied by enough cold air to cause “wintry road issues” during its occurrence. Thursday will feature fair, dry, but cool weather as high pressure dominates. A cold front will move across the region on Friday with some clouds and perhaps a passing rain shower, but any wet weather would be of brief duration.

TODAY: Cloudy. Periods of rain and some inland / higher elevation snow this morning, then steadier rain for several hours during this afternoon. Highs 40-47. Wind variable up to 10 MPH early, then E 5-15 MPH.

TONIGHT: Cloudy early with rain ending. Patchy fog during the evening. Partial clearing overnight. Lows 32-39. Wind N 5-15 MPH.

TUESDAY: Intervals of clouds and sun. A brief passing rain/mix/snow shower possible. Highs 46-53. Wind W 10-20 MPH, higher gusts.

TUESDAY NIGHT: Partly cloudy evening. Mostly cloudy overnight. Lows 31-38. Wind W 5-15 MPH, diminishing.

WEDNESDAY: Cloudy through midday with a period of rain, some mix/snow possible interior higher elevations. Thinning clouds during the afternoon. Highs 40-47. Wind variable 5-15 MPH.

WEDNESDAY NIGHT: Clearing. Lows 25-32. Wind NW 5-15 MPH, higher gusts.

THURSDAY: Sunny to partly cloudy. Highs 48-55. Wind W 5-15 MPH.

THURSDAY NIGHT: Partly cloudy. Lows 28-35. Wind W to SW 5-15 MPH.

FRIDAY: Partly sunny. A passing shower of rain and higher elevation mix possible. Highs 45-52. Wind W to NW 10-20 MPH, higher gusts.

DAYS 6-10 (MARCH 29 – APRIL 2)

A sunrise partial eclipse occurs on Saturday March 29. There may be enough clear sky that morning to see it, but this is highly uncertain. Fine-tuning to come. An unsettled pattern is indicated for end March / start April. It starts out cool and may feature a brief warm shot before another chill-down. Details of disturbances and resultant precipitation threats TBD.

DAYS 11-15 (APRIL 3-7)

An unsettled pattern with below normal temperatures for early April.

Comments open on this post for 7 days.

DAYS 1-5 (MARCH 23-27)

A quick update for your Sunday. No big changes to the overall forecast. Today’s weather will be considerably cooler than yesterday, and also windy. But expect dry weather with sunshine and some passing fair weather clouds. Winds settle down by tonight but clouds advance ahead of our next low pressure visit. This one messes up our Monday with a rain event, except it starts as some mix/snow over interior areas mainly near and west of I-95 and near and north of I-90 with some minor accumulation possible at first. Tuesday still looks chilly and breezy with a possible passing sprinkle/flurry. Another round of unsettled weather Wednesday with quick-passing low pressure, favoring a period of rain/mix in the southern half of the region. Fair weather is expected Thursday with a cool northwesterly air flow.

TODAY: Sun and passing clouds. Highs 45-52. Wind NW 10-20 MPH, gusts 25-35 MPH.

TONIGHT: Increasing clouds. Lows 30-37. Wind NW 5-15 MPH, diminishing.

MONDAY: Overcast. Rain likely, may begin as snow in some areas, especially north and west of Boston with a small accumulation possible on unpaved surfaces. Highs 40-47. Wind NE 5-15 MPH.

MONDAY NIGHT: Cloudy with areas of fog evening, rain tapering off. Breaking clouds overnight. Lows 35-42. Wind variable up to 10 MPH, becoming W 5-15 MPH.

TUESDAY: Intervals of clouds and sun. A brief passing rain/mix/snow shower possible. Highs 42-49. Wind W 10-20 MPH, higher gusts.

TUESDAY NIGHT: Partly cloudy evening. Mostly cloudy overnight. Lows 32-39. Wind W 5-15 MPH, diminishing.

WEDNESDAY: Mostly cloudy. Chance of rain, some mix possible, favoring southern areas. Highs 40-47. Wind variable 5-15 MPH.

WEDNESDAY NIGHT: Clearing. Lows 30-37. Wind NW 5-15 MPH, higher gusts.

THURSDAY: Sunny to partly cloudy. Highs 45-52. Wind NW 10-20 MPH, higher gusts.

DAYS 6-10 (MARCH 28 – APRIL 1)

An unsettled pattern is indicated. It starts out cool and may feature a brief warm shot mid-period before another chill-down. Details of disturbances and resultant precipitation threats TBD.

DAYS 11-15 (APRIL 2-6)

An unsettled pattern with below normal temperatures for early April. Details also TBD as we’ll be closer to a boundary and under fast flowing jet stream which leads to a lot of uncertainty on tracks/timing of systems.

DAYS 1-5 (MARCH 22-26)

Spring is here and the late March portion of it is a time when we have many weather mood swings typically, and some of what will be on display during this 5 day period, including this weekend. Today will feel more like mid spring with a shot of mild air. The daylight hours will be mainly dry as a strong cold front approaches from the west. It will be a breezy day taking a little bit away from the mildness of the air, but not too much. This front has little moisture to work with so only a brief passing rain shower favors areas north of I-90 this evening. A secondary trough may initiate a brief snow flurry in northern MA and/or southern NH overnight, leading a shot of colder air into the region, so our mild Saturday as followed by a chilly Sunday. A gusty wind will make high temps in the 40s feel more like 30s. Sunday night’s a cold one as clouds move in ahead of a low pressure area. This system will cross the region during Monday, and with enough cold air around it can and probably will start as snow over a portion of the region, especially north of I-90 and from I-95 westward, where some minor accumulation may occur before rain takes over. The storm departs Monday night, but cold air aloft means a lot of clouds can be around on Tuesday, but with no more than a passing light shower of rain/mix/snow, with a chilly breeze expected. The next low pressure system, small and fast-moving, brings another chance of unsettled weather to our region on Wednesday, but this one may scoot a little further south and be more of a side-swipe. I’ll follow the trends on that as we get closer to it.

TODAY: Sun through high clouds, eventually more clouds than sunshine. Highs 55-62 except 48-55 South Coast. Wind SW 5-15 MPH, gusts 20-25 MPH.

TONIGHT: Variably cloudy. A passing rain shower possible evening. A passing snow shower possible overnight. Lows 33-40. Wind SW shifting to NW 5-15 MPH, higher gusts.

SUNDAY: Sun and passing clouds. Highs 45-52. Wind NW 10-20 MPH, gusts 25-35 MPH.

SUNDAY NIGHT: Increasing clouds. Lows 30-37. Wind NW 5-15 MPH, diminishing.

MONDAY: Overcast. Rain likely, may begin as snow in some areas, especially north and west of Boston with a small accumulation possible on unpaved surfaces. Highs 40-47. Wind NE 5-15 MPH.

MONDAY NIGHT: Cloudy with areas of fog evening, rain tapering off. Breaking clouds overnight. Lows 35-42. Wind variable up to 10 MPH, becoming W 5-15 MPH.

TUESDAY: Intervals of clouds and sun. A brief passing rain/mix/snow shower possible. Highs 42-49. Wind W 10-20 MPH, higher gusts.

TUESDAY NIGHT: Partly cloudy evening. Mostly cloudy overnight. Lows 32-39. Wind W 5-15 MPH, diminishing.

WEDNESDAY: Mostly cloudy. Chance of rain, some mix possible, favoring southern areas. Highs 40-47. Wind variable 5-15 MPH.

DAYS 6-10 (MARCH 27-31)

The home stretch of March features an unsettled pattern and generally below normal temperatures. A disturbance or two can bring a few showers of rain/mix/snow to the region early period. A more substantial low pressure area may bring a more significant precipitation event after that.

DAYS 11-15 (APRIL 1-5)

An unsettled pattern with below normal temperatures for early April. Details TBD.

DAYS 1-5 (MARCH 21-25)

Our early spring weather pattern is going to feature more chilly than mild weather, and an active pattern bringing frequent disturbances through, but no major storms. One such system is passing by now as low pressure forms along a passing front. While it does intensify as it moves away, the bands of rain with it will taper off, maybe as some mix / wet snow in interior higher elevations, during this morning. A drying / clearing trend commences this afternoon, leading to a fair and chilly night, with gusty winds at first this afternoon and evening, which will settle down overnight as the low moves further away. No big changes to the weekend outlook. Saturday is the milder of the 2 days ahead of a trough and cold front. A brief rain shower as the front passes by Saturday evening and even a follow up snow flurry potential as colder air arrives overnight. This leads to a fair, blustery, chilly Sunday with a healthy northwesterly air flow. But on things move fairly quickly and the next storm system brings more precipitation for Monday. Enough cold air may be present for this to start as wet snow especially northern and interior sections, before it evolves to a rain event. Behind it comes more chilly air with a few rain / snow showers possible Tuesday.

TODAY: Cloudy morning with rain possibly ending as mix and/or snow, especially interior higher elevations. Partly sunny with a passing light rain or snow shower possible afternoon. Temperatures steady 38-45, may fall slightly. Wind N to NW 10-20 MPH, higher gusts.

TONIGHT: Clearing. Lows 26-33. Wind NW 5-15 MPH.

SATURDAY: Sunny morning. Clouds arrive afternoon – late-day rain shower possible. Highs 55-62. Wind NW shifting to SW 5-15 MPH, a few higher gusts.

SATURDAY NIGHT: Variably cloudy. A passing rain shower possible evening. A passing snow shower possible overnight. Lows 33-40. Wind SW shifting to NW 5-15 MPH, higher gusts.

SUNDAY: Partly to mostly sunny. Highs 45-52. Wind NW 10-20 MPH, higher gusts.

SUNDAY NIGHT: Increasing clouds. Lows 30-37. Wind NW 5-15 MPH, diminishing.

MONDAY: Overcast. Rain likely, may begin as snow in some areas, especially north and west of Boston. Highs 38-45. Wind NE 5-15 MPH.

MONDAY NIGHT: Overcast. Rain tapers off. Areas of fog. Temperatures steady 38-45 or may rise slightly. Wind variable 5-15 MPH.

TUESDAY: Mostly cloudy. A passing rain/snow shower possible. Highs 40-47. Wind NW 15-25 MPH.

DAYS 6-10 (MARCH 26-30)

Continued unsettled pattern with near to below normal temperatures. Precipitation events may include some mix/snow, depending on track/locations. March 26 and 28 are the 2 more likely days for these systems.

DAYS 11-15 (MARCH 31 – APRIL 4)

Cool and unsettled pattern continues heading out of March and into the beginning of April.

DAYS 1-5 (MARCH 20-24)

Welcome to spring 2025! The vernal equinox occurred at 5:01 a.m., and the new season greets us with marine air, a stratus cloud deck, and areas of fog. This will hold in place all day, along with some areas of moderate to dense fog to start the day, especially in eastern coastal areas. While a few patches of light drizzle may occur in response to the marine air mass, it will be rain-free during the day today, but not tonight, as a cold front moves across the region with a band of rain. As a new area of low pressure forms on the front, moves over our area, then departs to the east, the rain will come to an end Friday morning, but can become mixed with or even change to wet snow for a brief time over interior higher elevations before doing so. This can produce a brief minor accumulation on some surfaces, but it won’t last. A few lingering very light showers of rain and/or snow can take place during the afternoon as colder air moves in on a gusty north to northwest wind. The weekend will be ok in general. Saturday will be the warmer of the 2 days with a quick wind shift to southwest ahead of an approaching cold front. This front may produce a quick rain shower in the evening Saturday and maybe a brief snow shower overnight as a secondary trough passes. This will set up a fair but breezy and much cooler Sunday. An active weather pattern takes the next weather system in quickly with clouds advancing Sunday night and precipitation likely on Monday, mainly rain but may start as a period of snow especially inland / northern locations. Will monitor that as we get closer.

TODAY: Cloudy. Areas of fog, especially near the coast during this morning. Patchy light drizzle possible. Highs 44-51 coast, 51-58 inland. Wind E to SE up to 10 MPH.

TONIGHT: Cloudy. Rain likely. Lows 38-45. Wind variable 5-15 MPH.

FRIDAY: Cloudy morning with rain possibly ending as mix and/or snow, especially interior higher elevations. Partly sunny with a passing light rain or snow shower possible afternoon. Temperatures steady 38-45, may fall slightly. Wind N to NW 10-20 MPH, higher gusts.

FRIDAY NIGHT: Clearing. Lows 26-33. Wind NW 5-15 MPH.

SATURDAY: Sunny morning. Increasing clouds afternoon with a late day or evening rain/mix shower possible. Highs 48-55. Wind NW 5-15 MPH shifting to SW, a few higher gusts.

SATURDAY NIGHT: Mostly cloudy. A passing rain/mix/snow shower possible. Lows 35-42. Wind SW 5-15 MPH shifting to NW.

SUNDAY: Partly to mostly sunny. Highs 45-52. Wind NW 10-20 MPH, higher gusts.

SUNDAY NIGHT: Increasing clouds. Lows 30-37. Wind NW 5-15 MPH, diminishing.

MONDAY: Overcast. Rain likely, may begin as snow in some areas, especially north and west of Boston. Highs 38-45. Wind NE 5-15 MPH.

DAYS 6-10 (MARCH 25-29)

Continued unsettled pattern with near to below normal temperatures. Precipitation events may include some mix/snow, depending on track/locations.

DAYS 11-15 (MARCH 30 – APRIL 3)

Cooler and unsettled pattern continues for the end of March / start of April.

DAYS 1-5 (MARCH 19-23)

We are now under 24 hours from the official start of spring, with the occurrence of the vernal equinox at 5:01 a.m. Thursday. High pressure governs today’s weather, which will be pleasant by March standards. After a chilly morning, abundant sun will feel nice by noon and onward, as wind will be fairly light. But light wind and fair weather at this time of year often means onshore winds near the coast, and cooler conditions there. This will be true today. Clouds advance in from the ocean late-day and tonight due to the easterly air flow as higher clouds show up from west to east this evening and tonight ahead of our next trough and frontal system. This leads to a rather grey day for us to welcome spring with on Thursday, with a few patches of drizzle and areas of fog with increased presences of moist marine air. As the system from the west approaches, and a new low pressure area develops and heads into the region, a slug of rain will occur Thursday night into Friday morning. As the new low moves to our east, the rain can end as some mixed precipitation and snow for interior higher elevations and a few lingering very light showers of rain and/or snow can take place during the afternoon as colder air moves in on a gusty north to northwest wind. The weekend will be ok in general. Saturday will be the warmer of the 2 days with a quick wind shift to southwest ahead of an approaching cold front. This front may produce a quick rain shower in the evening Saturday and maybe a brief snow shower overnight as a secondary trough passes. This will set up a fair but breezy and much cooler Sunday.

TODAY: Mostly sunny. Highs 48-55 coast, 55-62 inland. Wind N up to 10 MPH shifting to E.

TONIGHT: Increasing clouds. Lows 35-42. Wind E under 10 MPH.

THURSDAY: Mostly cloudy. Highs 46-53. Wind SE 5-15 MPH.

THURSDAY NIGHT: Cloudy. Rain likely. Lows 38-45. Wind variable 5-15 MPH.

FRIDAY: Cloudy morning with rain possibly ending as mix and/or snow, especially interior higher elevations. Partly sunny with a passing light rain or snow shower possible afternoon. Temperatures steady 38-45, may fall slightly. Wind N to NW 10-20 MPH, higher gusts.

FRIDAY NIGHT: Clearing. Lows 26-33. Wind NW 5-15 MPH.

SATURDAY: Sunny morning. Increasing clouds afternoon with a late day or evening rain/mix shower possible. Highs 48-55. Wind NW 5-15 MPH shifting to SW, a few higher gusts.

SATURDAY NIGHT: Mostly cloudy. A passing rain/mix/snow shower possible. Lows 35-42. Wind SW 5-15 MPH shifting to NW.

SUNDAY: Partly to mostly sunny. Highs 50-57. Wind NW 5-15 MPH, higher gusts.

DAYS 6-10 (MARCH 24-28)

Unsettled pattern brings two storm chances during this 5 day period, either or both can contain some spring mix/snow, depending on locations / storm tracks. Details to come. Temperatures variable, overall close to normal.

DAYS 11-15 (MARCH 29 – APRIL 2)

Cooler and unsettled pattern indicated for the end of March / start of April.

DAYS 1-5 (MARCH 18-22)

Slow clearing will take place today as drier air arrives behind yesterday’s cold frontal passage. High pressure builds in tonight into Wednesday with fair and more tranquil weather after a gusty breeze is with us during today. Clouds return Thursday as the next trough approaches from the west. A frontal system will approach in association with the trough, and low pressure will develop and move across or just southeast of our area by early Friday. While this system starts as rain for the region, enough cold air can work in on its back side to cause the precipitation to mix with or turn to snow before ending, especially over interior higher elevations, but some mixing is possible even into the coastal plain, especially from Boston north. After a chilly Friday night, it will recover somewhat on Saturday ahead of another trough and accompanying frontal system that can bring a shower of rain or mix late Saturday. Vernal equinox (start of spring) occurs on Thursday morning at 5:01 a.m. EDT.

TODAY: Mostly cloudy start, then becoming mostly sunny. Highs 51-58. Wind NW 5-15 MPH, gusts 20-25 MPH.

TONIGHT: Mostly clear. Lows 33-40. Wind NW to N diminishing to under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 48-55 coast, 55-62 inland. Wind N up to 10 MPH shifting to E.

WEDNESDAY NIGHT: Increasing clouds. Lows 35-42. Wind E under 10 MPH.

THURSDAY: Cloudy. Highs 46-53. Wind SE 5-15 MPH.

THURSDAY NIGHT: Cloudy. Rain likely. Lows 38-45. Wind variable 5-15 MPH.

FRIDAY: Cloudy morning with rain possibly ending as mix and/or snow, especially interior higher elevations. Partly sunny with a passing light rain or snow shower possible afternoon. Temperatures steady 38-45, may fall slightly. Wind N to NW 10-20 MPH, higher gusts.

FRIDAY NIGHT: Clearing. Lows 26-33. Wind NW 5-15 MPH.

SATURDAY: Sunny morning. Increasing clouds afternoon with a late day or evening rain/mix shower possible. Highs 48-55. Wind NW 5-15 MPH shifting to SW.

DAYS 6-10 (MARCH 23-27)

Fair March 23. Unsettled pattern with a couple systems bringing precipitation threats in the March 24-27 time frame. Temperatures variable, averaging near normal.

DAYS 11-15 (MARCH 28 – APRIL 1)

Cooler and unsettled pattern indicated for the end of March / start of April.

DAYS 1-5 (MARCH 17-21)

We’ll have a wet St. Patrick’s Day today as a strong but slow-moving cold front moves west to east across the region and a wave of low pressure moves up along it, slowing its progress even more. It won’t be until tonight that we get rid of the rain from it, and sometime early Tuesday morning when we start to see clearing take place. But tomorrow does turn out to be a dry day with sun eventually returning, albeit with a gusty breeze as well. High pressure brings fair and more tranquil weather for Wednesday, but an increase in high clouds will be an indicator of the next approaching low pressure area. Spring arrives at 5:01 a.m. EDT with the occurrence of the vernal equinox on Thursday, but expect a mainly cloudy day with nighttime rain as low pressure and its frontal systems move into the region. This will bring a period of rain into Friday, which may end as mix/snow for some areas, especially interior higher elevations, as cold air arrives. A new low forms offshore and intensifies while pulling away via the Gulf of Maine, so expect a few lingering sprinkles of rain or flurries of snow with a gusty chilly breeze and breaking clouds Friday afternoon. The first full day of spring will feel a bit more like winter again…

TODAY: Overcast. Rain likely. Highs 53-60. Wind S 5-15 MPH, higher gusts.

TONIGHT: Cloudy. Rain ends evening. Patchy fog. Lows 33-40. Wind shifting to NW 5-15 MPH, higher gusts.

TUESDAY: Mostly cloudy start, then partly to mostly sunny. Highs 51-58. Wind NW 5-15 MPH, higher gusts.

TUESDAY NIGHT: Mostly clear. Lows 33-40. Wind NW to N diminishing to under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 48-55 coast, 55-62 inland. Wind N up to 10 MPH shifting to E.

WEDNESDAY NIGHT: Increasing clouds. Lows 35-42. Wind E under 10 MPH.

THURSDAY: Cloudy. Highs 46-53. Wind SE 5-15 MPH.

THURSDAY NIGHT: Cloudy. Rain likely. Lows 38-45. Wind variable 5-15 MPH.

FRIDAY: Cloudy morning with rain possibly ending as mix and/or snow, especially interior higher elevations. Partly sunny with a passing light rain or snow shower possible afternoon. Temperatures steady 38-45, may fall slightly. Wind N to NW 10-20 MPH, higher gusts.

DAYS 6-10 (MARCH 22-26)

Upper trough and associated surface low / frontal system brings clouds and a brief precipitation chance later March 22 to early March 23. Cooler trend. More unsettled weather heading into next week – details TBD.

DAYS 11-15 (MARCH 27-31)

Cooler and unsettled pattern indicated for the end of March.

Comments will be open for 7 days…

DAYS 1-5 (MARCH 16-20)

This 5-day forecast portion takes us through the final 4 days of winter and to the day we change seasons from winter to spring, but the most “spring-like” feeling weather is going to come today as a strengthening southerly wind overtakes the region. It starts out rather foggy in a good portion of the region however, as low level moisture has increased with a marine air mass driven into southern New England by the south wind behind a warm front. While the fog dissipates, the clouds will dominate, although it will stay mainly rain-free through the day with the exception of a few patches of light drizzle with the fog this morning and a possible passing sprinkle of rain in a few locations midday and afternoon. The mild air will push high temps to 60+ for most areas, but a modifying influence of the chilly ocean water will keep coastal areas, especially Cape Cod / South Coast, cooler. A slow-moving cold front will push into the region tonight and take most of the day Monday (St. Patrick’s Day) to pass by, slowed by an additional wave of low pressure. This results in widespread rain showers much of this time. Monday night, we dry out / clear out from west to east behind the front. Tuesday’s weather will be dry and breezy as high pressure builds eastward through the Great Lakes. Continued dry weather Wednesday will result from high pressure overhead extending into southeastern Canada, but also allow for a bigger temperature contrast from cool eastern coastal areas with an onshore breeze to much milder conditions further inland. Thursday’s weather will feature an increase in clouds as the next trough starts to approach from the west, but the early thought is that we’ll stay dry during the day and see a chance of some rainfall arriving at night. The vernal equinox occurs at 5:01 a.m. EDT Thursday March 20.

TODAY: Cloudy. Areas of fog and patchy light drizzle this morning. A passing sprinkle of rain possible midday on. Highs 51-58 South Coast, 59-66 elsewhere. Wind S increasing to 10-20 MPH, gusts around 30 MPH.

TONIGHT: Cloudy. Widespread rain showers. Slight chance of a thunderstorm. Lows 48-55. Wind S 10-20 MPH, higher gusts.

MONDAY: Cloudy with rain showers likely through mid afternoon, diminishing west to east, then late-day breaking clouds, especially west of I-95. Highs 55-62. Wind S 5-15 MPH, higher gusts, shifting to NW.

MONDAY NIGHT: Clearing. Lows 35-42. Wind NW 5-15 MPH, higher gusts.

TUESDAY: Mostly sunny. Highs 52-59. Wind NW 5-15 MPH, higher gusts.

TUESDAY NIGHT: Mostly clear. Lows 33-40. Wind NW to N diminishing to under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 48-55 coast, 55-62 inland. Wind N up to 10 MPH shifting to E.

WEDNESDAY NIGHT: Mostly clear. Lows 35-42. Wind E under 10 MPH.

THURSDAY: Increasing clouds. Chance of rain at night. Highs 46-53. Wind SE 5-15 MPH.

DAYS 6-10 (MARCH 21-25)

The first full day of spring on March 21 might remind you more of winter with a chill northerly wind as a cold front moves offshore, rain that may end as mix/snow and some lingering rain/mix/snow showers behind that. The March 22-23 weekend will feature an upper level low crossing the region and while it will be precipitation-free most of the time, there can be some scattered rain/mix/snow showers with fairly cool weather dominant. Additional unsettled weather is a potential for later in the period as well.

DAYS 11-15 (MARCH 26-30)

Cooler and unsettled pattern indicated for late month.

Starting with the next update, the NOAA / NWS Staffing Discussion will be put up for the entire week, with comments allowed to be made for 7 days. Since the discussion is limited here, like what I did with the separate covid posts back in 2020 / 2021, one post per week will suffice. It’s easy to find on the side menu if you wish to add commentary at any time during the week!

DAYS 1-5 (MARCH 15-19)

Early this morning, a layer of marine stratus clouds and some patchy fog made for a grey start to the day across much of the region. Exception: Merrimack Valley / southern NH, where this layer didn’t reach, and once the sun rose above it in the sky to the east, it’s filtered by high clouds above. But some advancement of the stratus deck into that region can occur early on, before we see a thinning / breaking trend with some partial sun in other areas today. I don’t have faith in complete clearing, but we’ll see how much sun can manage to make its way through the clouds as we go through the day. An increasing southerly air flow as a warm front goes by starts to pull more low level moisture into our region with time, and this will start to initiate lower clouds again coming off the ocean to the south. This will become more pronounced tonight and Sunday with a stronger southerly wind. We should be dry (as in rain-free) over most areas through the daylight hours of Sunday, with the exception of a few sprinkles and drizzle as a result of that increasing low level moisture as we head through tonight and Sunday. The trade-off will be unseasonably warm air, with many areas exceeding 60 for high temps on Sunday. However, the air coming off the chilly water closer to the South Coast will have a modifying effect in those areas, which don’t make it to 60. The large storm system that has been impacting the middle of the US (Texas, Plains, Midwest) with everything from tornadoes and thunderstorms to dust storms to a snowstorm, depending on location, will track through the Great Lakes into Canada as we head through the weekend. While additional severe thunderstorms occur from the Midwest to Southeast today, we’ll not have to worry about that, only waiting for the cold front’s rain band to move into and through the region Sunday evening into Monday. This will be a slow process, and a wave of low pressure forming on the front as it starts to push off the East Coast may even prolong the rain a bit longer here into Monday, before some drying arrives from the west. The timing of this will determine whether or not we see any breaks / sun before sunset on St. Patrick’s Day. High pressure builds Tuesday and Wednesday with fair weather. Tuesday will feature a cool northwesterly breeze. Wednesday will have less wind overall, but a cooling coastal sea breeze. While Tuesday’s temperatures are more uniform for highs, Wednesday we can see a larger contrast from coastal to inland areas.

TODAY: Early to mid morning overcast with areas of fog except partial sun far northern MA and southern NH. Mostly cloudy to partly sunny thereafter. Highs 49-56, coolest coastal areas. Wind SE to S up to 10 MPH.

TONIGHT: Mostly cloudy. A patch of drizzle and areas of fog possible. Lows 44-51. Wind S up to 10 MPH.

SUNDAY: Mostly cloudy. A passing light rain shower possible. Highs 51-58 South Coast, 59-66 elsewhere. Wind S increasing to 10-20 MPH, gusts around 30 MPH.

SUNDAY NIGHT: Cloudy. Widespread rain showers. Slight chance of a thunderstorm. Lows 48-55. Wind S 10-20 MPH, higher gusts.

MONDAY: Cloudy with rain showers likely through mid afternoon, diminishing west to east, then late-day breaking clouds, especially west of I-95. Highs 55-62. Wind S 5-15 MPH, higher gusts, shifting to NW.

MONDAY NIGHT: Clearing. Lows 35-42. Wind NW 5-15 MPH, higher gusts.

TUESDAY: Mostly sunny. Highs 52-59. Wind NW 5-15 MPH, higher gusts.

TUESDAY NIGHT: Mostly clear. Lows 33-40. Wind NW to N diminishing to under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 48-55 coast, 55-62 inland. Wind N up to 10 MPH becoming variable inland with coastal sea breezes developing.

DAYS 6-10 (MARCH 20-24)

The vernal equinox (astronomical start of spring) occurs at 5:01 a.m. EDT March 20. Our weather pattern during this period turns more unsettled, starting mild with one frontal system bringing some wet weather between late March 20 and early March 21. Additional rain/mix/snow showers possible with cooler weather after that.

DAYS 11-15 (MARCH 25-29)

Yesterday turned out nicer in terms of sunshine than I’d expected even in the short term. Marine stratus clouds have made a comeback overnight, but not enough to prevent a lot of the region from having the chance to see the lunar eclipse. Nice view from here in fact – glad I stayed up for it! The low clouds will break up again today for at least partial sun while some higher clouds drift across the sky above, and it’ll be a little bit milder than yesterday, though we still sit on the cooler side of a frontal boundary, which will finally lift through the region by early Saturday. This sets us up for an increasing southerly air flow ahead of a slow-moving cold front, which won’t arrive until Sunday night / early Monday. While much of the weekend itself is rain-free, we do run the risk of a passing rain shower any time Sunday, before a more widespread band of showers arrives at night into Monday with the front. We may even see some embedded thunder with it. Stronger southerly winds will occur Sunday after a more modest breeze Saturday. This air flow at this time of year keeps the South Coast cooler than the remainder of the region, and we’ll see that as well. A drying trend is expected to get underway from west to east by midday Monday, and we may see some clearing before the day is over on St. Patrick’s Day. This will be follows by fair weather Tuesday as high pressure builds toward the region.

MONDAY NIGHT: Clearing. Lows 35-42. Wind W 5-15 MPH, higher gusts.

TUESDAY: Mostly sunny. Highs 52-59. Wind W 10-20 MPH.

DAYS 6-10 (MARCH 19-23)

The final hours of winter will be met with fair and milder weather as high pressure builds off the Mid Atlantic Coast. Vernal equinox – 5:01 a.m. EDT March 20. The mild air is good for both March 19 and 20 before a strong cold front arrives and flips it to a chilly pattern late next week with an initial band of rain showers and then a few scattered rain/snow showers thereafter.

DAYS 11-15 (MARCH 24-28)

Cooler and unsettled pattern indicated. Details to come.
